Description

The present invention relates to a component data generation device and a component mounter that generate component data used during a component recognition process to recognize the state of components held by a holder.

A component mounter for mounting electronic components (hereinafter simply referred to as "components") on a substrate such as a printed wiring board is equipped with a head unit having a holder for holding the components. The head unit moves to a predetermined component mounting position while holding the component with the holder, and mounts the component on the substrate at the component mounting position.

The state in which the component is held by the holder is not necessarily constant. For this reason, before the component is mounted on the board, a component recognition process is performed to recognize the state in which the component is held based on a component image captured of the component held by the holder. Based on the recognition results from this component recognition process, the mounting operation of the component on the board by the head unit is controlled. This improves the accuracy of mounting the component on the board.

Patent Document 1 discloses a technique for creating part data used during part recognition processing. In the technique disclosed in Patent Document 1, a superimposed image in which a graphic image based on part data is superimposed on a part image is displayed on a monitor. At this time, an enlarged image in which a partial area of the superimposed image is enlarged is displayed on the monitor. By checking the enlarged image displayed on the monitor, an operator can accurately grasp the amount of deviation of the graphic image relative to the part image. Therefore, the operator can create accurate part data by inputting each piece of data that constitutes the part data while checking the enlarged image.

Patent No. 3678895

When performing data entry work while checking an enlarged image, the operator will need to change the image display magnification in order to check the entire superimposed image. In addition, when checking an enlarged image of another area in the superimposed image, the operator will need to change the position of the area to be enlarged in the superimposed image. If such operations are performed frequently, it may become difficult to efficiently create part data.

The object of the present invention is to provide a component data generation device and component mounter that can efficiently create accurate component data.

A part data generation device according to one aspect of the present invention is a device for generating part data used in a part recognition process for recognizing a holding state of a part held by a holder, the part data generation device including: an operation unit that accepts an input operation related to generation of the part data, a generation unit that, when a data input operation for inputting parameter data related to features of the part that constitutes the part data is performed via the operation unit, generates a graphic image of the part and generates the part data based on input data corresponding to the data input operation, a display unit that displays a superimposed image in which the graphic image is superimposed on a part image corresponding to the part that is the target of input of the parameter data, and a display control unit that, when an operation for inputting a command to enlarge a plurality of attention areas in the superimposed image is performed via the operation unit, controls the display unit to display a plurality of enlarged images in which the plurality of attention areas are individually enlarged on the same screen.

According to this part data generation device, when a data input operation for inputting data for each parameter constituting the part data is performed via an operation unit, the generation unit generates a graphic image of the part and part data based on the input data corresponding to the data input operation. Then, a superimposed image in which the graphic image is superimposed on the part image is displayed on the display unit. At this time, when an operation for inputting a command to enlarge multiple attention areas in the superimposed image is performed via the operation unit, the display control unit controls the display unit to display each enlarged image in which each of the multiple attention areas is enlarged on the same screen.

In this case, enlarged images of the multiple attention areas in the superimposed image are displayed on the same screen of the display unit. By checking the enlarged images of the multiple attention areas displayed on the display unit, the operator can accurately grasp the amount of deviation of the graphic image relative to the part image. This allows the operator to check whether the input data for parameters related to the features of the part that make up the part data is accurate. This makes it possible to create part data with high accuracy. Moreover, because enlarged images of the multiple attention areas in the superimposed image are displayed by a single operation of inputting an enlarged display command, the number of operations required to change the position of the target area for enlarged display in the superimposed image can be reduced. This allows the operator to efficiently create part data while checking the enlarged images displayed on the display unit.

In the above-mentioned part data generating device, the generating unit updates and generates the graphic image and the part data each time the data input operation is performed via the operating unit. Then, the display control unit controls the display unit to display the superimposed image in which the updated graphic image is superimposed on the part image.

In this embodiment, each time a data input operation is performed to input parameter data for a part, a graphic image based on the input data corresponding to that data input operation is updated. Then, a superimposed image in which the updated graphic image is superimposed on the part image is displayed on the display unit. In this case, the operator can accurately grasp the amount of deviation of the graphic image relative to the part image each time a data input operation is performed. This makes it possible to efficiently create accurate part data that corresponds to a graphic image that matches the part image.

In the above-mentioned part data generating device, the display control unit controls the display unit so that the overall image showing the entire superimposed image and each of the enlarged images are displayed to fit within a single image display area on the same screen, or are displayed individually in separate image display areas on the same screen.

In this embodiment, the overall image showing the entire superimposed image and each enlarged image are displayed on the same screen of the display unit. In this case, the operator can check whether each input data constituting the part data is accurate by checking both the enlarged image and the overall image. This allows for efficient creation of accurate part data.

In the above-mentioned part data generation device, when an operation to input a display switching command to switch the display format of the superimposed image is performed via the operation unit, the display control unit controls the display unit so that, in response to the display switching command, a full image showing the entire superimposed image and each of the enlarged images are switched and displayed.

In this aspect, the operator can switch the display mode of the superimposed images on the display unit between a mode in which each enlarged image is displayed and a mode in which the entire image is displayed, by performing an operation to input a display switching command. Therefore, the operator can check whether each input data constituting the part data is accurate by switching between the display of each enlarged image and the entire image. This allows for efficient creation of part data with high accuracy.

In the above-mentioned part data generation device, the display control unit controls the display unit so that an attention area marker frame, which marks the range of each of the plurality of attention areas on the overall image, is displayed superimposed on the overall image.

In this embodiment, a region of interest marker frame indicating the region of interest to be enlarged in the superimposed image is displayed superimposed on the entire image. In this case, the operator can easily confirm the region of interest to be enlarged in the entire superimposed image by using the region of interest marker frame as a marker.

In the above-mentioned part data generating device, the display control unit controls the display unit so that each of the enlarged images is displayed at a preset standard enlargement magnification. When an operation to input a magnification change command to change the standard enlargement magnification is performed via the operation unit, the display control unit controls the display unit so that each of the enlarged images is displayed at a magnification according to the magnification change command.

In this embodiment, each enlarged image is displayed at a preset standard magnification. In this case, the operator does not need to specify the magnification of each enlarged image. In addition, the operator can view each enlarged image at a magnification different from the standard magnification by inputting a magnification change command.

The part data generation device further includes a setting unit that, when an operation of inputting a part type designation command that designates the type of the part is performed via the operation unit, sets the parameters and sets the positions of the multiple attention areas according to the type of the part indicated by the part type designation command.

The characteristic parameters of a part differ depending on the type of part. Therefore, the position of the attention area to be enlarged and displayed in the superimposed image in order to create accurate part data also differs depending on the type of part. Therefore, in the part data generation device, the setting unit sets the parameters and the position of the attention area depending on the type of part indicated by the part type designation command input to the operation unit. In this case, the generation unit can generate an appropriate graphic image corresponding to the part image that differs for each type of part based on the input data related to the parameters set according to the type of part. In addition, the display control unit can display an enlarged image of the attention area set according to the type of part on the display unit. Therefore, the operator can check whether the input data of the parameters set according to the type of part is accurate by checking the enlarged image of the attention area according to the type of part. This makes it possible to create accurate part data according to the type of part.

In the above-mentioned component data generation device, when the component indicated by the component type designation command is a component having multiple terminal rows in which multiple terminals are arranged in a predetermined arrangement direction relative to the component body, the setting unit sets the number of terminals for each terminal row, the pitch between the terminals, the terminal width, and the position of the reference terminal as the parameters, and sets the multiple attention areas based on each area on the component image corresponding to each terminal located at one end and the other end of the arrangement direction for each terminal row.

In this aspect, if the part indicated by the part type designation command input to the operation unit is a part having multiple terminal rows on the part body, each area on the part image corresponding to each terminal located at one end and the other end of the arrangement direction of each terminal row is set as a focus area and each enlarged image is displayed. In this case, the operator can check whether the input data regarding the number of terminals for each terminal row, the pitch between terminals, the terminal width, and the position of the reference terminal, which are set as parameters, are accurate by checking each enlarged image of each focus area corresponding to each terminal located at one end and the other end of each terminal row. This makes it possible to create accurate part data according to the type of part.

In the above-mentioned component data generation device, when the component indicated in the component type designation command is a component having a terminal with a width equal to or greater than a predetermined value provided on the component body, the setting unit sets the multiple attention areas based on the areas on the component image that correspond to the corners of the terminal.

In this aspect, if the part indicated by the part type designation command input to the operation unit is a part with a terminal with a width equal to or greater than a predetermined value provided on the part body, the area on the part image corresponding to the corner of the terminal is set as the attention area and an enlarged image is displayed. In this case, the operator can check whether the input data constituting the part data is accurate by checking the enlarged image of the attention area corresponding to the corner of the terminal with a width equal to or greater than a predetermined value. This makes it possible to create part data with high accuracy according to the type of part.

In the above-mentioned component data generation device, when the component indicated in the component type designation command is a component that does not have a terminal on the component body, the setting unit sets the multiple attention areas based on areas on the component image that correspond to corners of the component body.

In this aspect, if the part indicated by the part type designation command input to the operation unit is a part that does not have a terminal on the part body, an area on the part image that corresponds to a corner of the part body is set as the attention area and an enlarged image is displayed. In this case, the operator can check whether the input data that constitutes the part data is accurate by checking the enlarged image of the attention area that corresponds to the corner of the part body. This makes it possible to create accurate part data according to the type of part.

In the above-mentioned part data generating device, when an operation to input a position change command to change the position of the enlarged display in the superimposed image is performed via the operation unit while each of the enlarged images obtained by enlarging the multiple attention areas set by the setting unit is displayed, the display control unit controls the display unit to change the position of the enlarged display in response to the position change command.

In this embodiment, the display control unit changes the position of the superimposed image to be enlarged in response to the operator's input operation of a position change command. In this case, the operator can cause the display unit to display an enlarged image that is an enlargement of the desired position indicated by the position change command, by performing an operation of inputting a position change command.

In the above-mentioned part data generating device, the display control unit controls the display unit so that the enlarged images of the standard enlarged display number are displayed on the same screen. When the number of attention areas set by the setting unit is greater than the standard enlarged display number, the display control unit controls the display unit so that the enlarged images of the attention areas in the number corresponding to a display number change command input via the operation unit for changing the standard enlarged display number are displayed on the same screen.

In this aspect, the display control unit controls the display unit so that the enlarged images of the standard enlarged display number are displayed on the same screen. In this case, it is possible to prevent the size of each enlarged image of the standard enlarged display number on the display screen of the display unit from becoming too small or too large. This allows the operator to accurately grasp the amount of deviation of the graphic image relative to the part image by checking each enlarged image displayed on the same screen of the display unit. Furthermore, if the number of attention areas set by the setting unit is greater than the standard enlarged display number, the operator can cause the enlarged images of the attention areas set by the setting unit to be displayed on the same screen of the display unit by performing an operation to input a display number change command.

In the above-mentioned part data generation device, when the part recognition process is performed using the part data, the display control unit controls the display unit to display a superimposed image for part recognition in which the graphic image is superimposed on a part image for part recognition captured in the part recognition process.

In this aspect, when part recognition processing is performed using part data generated based on input data corresponding to a data input operation, a superimposed image for part recognition in which a graphic image based on the part data is superimposed on a part image for part recognition captured in the part recognition processing is displayed on the display unit. In this case, by checking the superimposed image for part recognition, the operator can confirm whether or not the holding state of the part by the holder can be accurately recognized in the part recognition processing using the part data.

The above-mentioned part data generation device further includes a calculation unit that calculates the amount of deviation of the graphic image relative to the part image in the superimposed image for part recognition, and outputs position data of an excessive deviation area when the amount of deviation exceeds a predetermined allowable threshold. In this case, the display control unit controls the display unit so that an excessive deviation mark frame that marks the range of the excessive deviation area on the superimposed image for part recognition is superimposed and displayed.

In this embodiment, an excessive deviation mark frame that indicates the range of the excessive deviation area on the superimposed image for part recognition is superimposed and displayed. In this case, the operator can easily confirm the position of the excessive deviation area where the deviation amount of the graphic image relative to the part image exceeds the allowable threshold value by using the excessive deviation mark frame as a mark.

A component mounter according to another aspect of the present invention includes a head unit having a holder for holding components and mounting the components held by the holder onto a board, an imaging unit for imaging the components held by the holder and acquiring component images, a mounting memory unit for storing component data generated by the component data generating device, a component recognition unit for performing a component recognition process for recognizing the holding state of the components held by the holder based on the component images and the component data, and a mounting control unit for controlling the head unit based on the recognition results of the component recognition unit.

According to this component mounter, component recognition processing of the state of components being held by the holder is performed based on the component data generated by the component data generation device. In other words, the component mounter performs component recognition processing based on accurate component data. This type of component recognition processing makes it possible to accurately recognize the state of components being held by the holder. Therefore, the component mounting operation by the head unit, which is controlled based on the recognition results of the component recognition processing, improves the accuracy of component mounting on the board.

As described above, the present invention provides a component data generation device and a component mounter that can efficiently create accurate component data.

The following describes a component data generation device and a component mounter equipped with the same according to an embodiment of the present invention with reference to the drawings.

A component mounter 1 to which a component data generating device 10 is applied will be described with reference to Figs. 1 and 2. In Fig. 2, directional relationships are shown using XYZ orthogonal coordinate axes. The X-axis direction is parallel to the horizontal plane, the Y-axis direction is perpendicular to the X-axis direction on the horizontal plane, and the Z-axis direction is an up-down direction perpendicular to both the X-axis and Y-axis directions. One side in the X-axis direction is called the "+X side", and the other side opposite to the one side in the X-axis direction is called the "-X side". One side in the Y-axis direction is called the "+Y side", and the other side opposite to the one side in the Y-axis direction is called the "-Y side". One side in the Z-axis direction (upper side) is called the "+Z side", and the other side opposite to the one side in the Z-axis direction (lower side) is called the "-Z side".

The component mounter 1 is a device that generates component data D2 by a component data generation device 10, and uses the component data D2 to mount (mount) electronic components (hereinafter referred to as "components") on a substrate P to produce a component-mounted board. The component mounter 1 includes a device main body 1a, a moving frame 2, a conveyor 3, a component supply unit 4 to which a feeder 5 is attached, a head unit 6, a first drive mechanism 7, a second drive mechanism 8, a mounting control unit 9, a mounting memory unit 9M, and the component data generation device 10.

The device main body 1a is a structure in which the various components that make up the component mounter 1 are arranged, and is formed in a roughly rectangular shape when viewed in a plan view from the Z-axis direction. The conveyor 3 extends in the X-axis direction and is arranged in the device main body 1a. The conveyor 3 transports the board P in the X-axis direction. The board P is transported on the conveyor 3 and positioned at a predetermined work position (a position where components are mounted on the board P).

The component supply units 4 are arranged in four locations, two in each direction along the X axis, on the +Y and -Y sides of the device body 1a in the Y axis direction. The component supply units 4 are located in the device body 1a in an area where multiple feeders 5 are installed side by side, and the set positions of each feeder 5 are defined for each component to be picked up by the suction nozzle 63 provided on the head unit 6, which will be described later.

The feeder 5 is detachably attached to the component supply unit 4 of the device main body 1a. As long as the feeder 5 is configured to be able to supply components, its component supply method is not particularly limited. As the feeder 5, for example, a tape feeder that supplies components using a tape as a carrier, a tray feeder that supplies components by moving a pallet including a tray on which the components are placed, or a stick feeder that supplies components stored in a cylindrical stick while pushing the components out of the stick can be used. In this embodiment, the feeder 5 is a tape feeder.

The moving frame 2 extends in the X-axis direction and is supported on the device main body 1a so that it can move in a predetermined moving direction (Y-axis direction). The head unit 6 is mounted on this moving frame 2.

The head unit 6 is mounted on the moving frame 2 so that it can move in the X-axis direction. That is, the head unit 6 can move in the Y-axis direction with the movement of the moving frame 2, and can move in the X-axis direction along the moving frame 2. The head unit 6 is movable between the component supply position of the feeder 5 attached to the component supply unit 4 and a predetermined work position of the board P transported by the conveyor 3. The head unit 6 takes out and holds a component from the feeder 5 at the component supply position, and mounts (mounts) the held component on the board P at the work position.

The head unit 6 includes a head body 61, a rotating body 62, and a suction nozzle 63. The head body 61 constitutes the main body of the head unit 6. The rotating body 62 is formed in a cylindrical shape and is provided on the head body 61 so as to be rotatable about a vertical axis (axis extending in the Z-axis direction) as the center of rotation. A plurality of suction nozzles 63 are arranged at a predetermined interval in the circumferential direction on the outer peripheral edge end of the rotating body 62. The suction nozzle 63 is a holder that can suck and hold a component supplied to a component supply position by the feeder 5. The head unit 6 mounts the component sucked and held by the suction nozzle 63 on the substrate P. The suction nozzle 63 can be connected to any of a negative pressure generating device, a positive pressure generating device, and the atmosphere via an electric switching valve. In other words, the suction nozzle 63 can suck and hold a component (remove a component) by the suction nozzle 63 by supplying negative pressure to the suction nozzle 63, and then the suction and holding of the component is released by supplying positive pressure.

The suction nozzle 63 is provided on the rotating body 62 so that it can move up and down in the Z-axis direction and rotate around a nozzle axis extending in the Z-axis direction. The suction nozzle 63 can move up and down along the Z-axis direction between a suction holding position where the component supplied to the component supply position by the feeder 5 can be suctioned and held, and a retreat position above the suction holding position. That is, when suctioning and holding a component supplied to the component supply position, the suction nozzle 63 descends from the retreat position to the suction holding position, and suctions and holds the component at the suction holding position. On the other hand, after suctioning and holding the component, the suction nozzle 63 rises from the suction holding position to the retreat position. Furthermore, the suction nozzle 63 can move up and down along the Z-axis direction between a component mounting position set on the substrate P to mount the suction-held component on the substrate P, and the retreat position. That is, when mounting the suction-held component on the substrate P, the suction nozzle 63 descends from the retreat position to the component mounting position, and mounts the component on the substrate P at the component mounting position. Meanwhile, after mounting the component, the suction nozzle 63 rises from the component mounting position to the retreat position.

The first drive mechanism 7 is disposed at the +X and -X ends of the device body 1a. The first drive mechanism 7 is a mechanism that moves the moving frame 2 in the Y-axis direction. The first drive mechanism 7 is configured to include, for example, a drive motor, a ball screw shaft that extends in the Y-axis direction and is connected to the drive motor, and a ball nut that is disposed on the moving frame 2 and screws into the ball screw shaft. The first drive mechanism 7 configured in this way moves the moving frame 2 in the Y-axis direction by the ball nut moving back and forth along the ball screw shaft as the ball screw shaft is rotated and driven by the drive motor.

The second drive mechanism 8 is disposed on the moving frame 2. The second drive mechanism 8 is a mechanism that moves the head unit 6 in the X-axis direction along the moving frame 2. Like the first drive mechanism 7, the second drive mechanism 8 is configured to include, for example, a drive motor, a ball screw shaft that extends in the X-axis direction and is connected to the drive motor, and a ball nut that is disposed on the head unit 6 and screws into the ball screw shaft. The second drive mechanism 8 configured in this way moves the head unit 6 in the X-axis direction by the ball nut moving back and forth along the ball screw shaft as the ball screw shaft is rotated and driven by the drive motor.

In this example, the first drive mechanism 7 and the second drive mechanism 8 are configured to move the moving frame 2 and the head unit 6 via a ball screw shaft using a drive motor. However, they may also be configured to directly drive the moving frame 2 and the head unit 6 using, for example, a linear motor as a drive source.

As shown in Figures 1 and 2, the component mounter 1 further includes a first imaging unit C1, a second imaging unit C2, and a third imaging unit C3.

The first imaging unit C1 is an imaging camera installed between the conveyor 3 and the component supply unit 4 on the device main body 1a, and equipped with an imaging element such as a complementary metal-oxide-semiconductor (CMOS) or a charged-coupled device (CCD). While the head unit 6 is moving from the component supply unit 4 toward the board P on the conveyor 3, the first imaging unit C1 captures an image of the component held by the suction nozzle 63 from below to obtain a component image. The component image is input to the mounting control unit 9 described below, and is referenced when the component recognition unit 95 performs a recognition process of the state in which the component is held by the suction nozzle 63. The component image is also stored in the memory unit 11 of the component data generation device 10 described below.

The second imaging unit C2 is disposed in the head body 61 of the head unit 6, and is an imaging camera equipped with an imaging element such as a CMOS or CCD. The second imaging unit C2 images the component supply position of the feeder 5 from diagonally above, with the head unit 6 positioned so that the suction nozzle 63 is located directly above the component supply position set in the feeder 5. The image acquired by imaging with the second imaging unit C2 is referenced when recognizing the posture of the component supplied to the component supply position of the feeder 5.

The third imaging unit C3 is disposed in the head body 61 of the head unit 6, and is an imaging camera equipped with an imaging element such as a CMOS or CCD. The third imaging unit C3 captures images of the marks from above in order to recognize the various marks affixed to the top surface of the substrate P on the conveyor 3. The amount of positional deviation of the substrate P from the origin coordinates is detected by the recognition of the marks on the substrate P by the third imaging unit C3.

The mounting memory unit 9M stores board data D1 and component data D2 referenced by the mounting control unit 9. The board data D1 is data composed of various information necessary for the mounting control unit 9 to control the component mounting process and the like. The information constituting the board data D1 includes component information for identifying the component, feeder information for identifying the feeder 5, nozzle information for identifying the suction nozzle 63, head information for identifying the head unit 6, target suction position information indicating the target suction position when the component is picked up by the suction nozzle 63, and target mounting position information indicating the target mounting position of the component set on the board P. The component data D2 is data generated by the component data generation device 10. Details of this component data D2 will be described later together with the component data generation device 10.

The mounting control unit 9 is composed of a CPU (Central Processing Unit), a ROM (Read Only Memory) that stores a control program, and a RAM (Random Access Memory) that is used as a working area for the CPU. The mounting control unit 9 controls the operation of each component of the component mounter 1 and executes various arithmetic processing by the CPU executing the control program stored in the ROM. The mounting control unit 9 controls the operation of each component according to the board data D1 stored in the mounting memory unit 9M. As shown in FIG. 1, the mounting control unit 9 mainly includes a board transport control unit 91, a component supply control unit 92, a head control unit 93, an imaging control unit 94, and a component recognition unit 95 as its functional components.

The board transport control unit 91 controls the conveying operation of the board P by the conveyor 3. The component supply control unit 92 controls the component supply process of each of the multiple feeders 5 arranged in the component supply unit 4 according to the component information and feeder information of the board data D1. The head control unit 93 controls the suction nozzle 63 by controlling the head unit 6 according to the component information, nozzle information, head information, target suction position information, and target mounting position information of the board data D1. As a result, the head control unit 93 causes the suction nozzle 63 to perform a component suction process and the head unit 6 to perform a component mounting process corresponding to each of the multiple target mounting positions set on the board P. The imaging control unit 94 controls the imaging operations of the first imaging unit C1, the second imaging unit C2, and the third imaging unit C3.

The component recognition unit 95 performs a component recognition process to recognize the holding state of the component adsorbed and held by the suction nozzle 63 based on the component image acquired by the first imaging unit C1 and the component data D2 generated by the component data generating device 10. The component recognition unit 95 recognizes the position of the component relative to the suction nozzle 63 based on the component image and the component data D2, and recognizes the posture of the component adsorbed and held by the suction nozzle 63.

The component recognition results by the component recognition unit 95 are referenced by the head control unit 93. In other words, the head control unit 93 controls the component mounting process by the head unit 6 based on the component recognition results by the component recognition unit 95. The component mounting process by the head unit 6, which is controlled based on the recognition results of the component recognition process by the component recognition unit 95, improves the accuracy of mounting components on the substrate P.

Next, the part data generating device 10 will be described with reference to Figs. 3 to 19 in addition to Fig. 1. The part data generating device 10 is a device that generates part data D2 used during part recognition processing by the part recognition unit 95. The part data generating device 10 is configured, for example, by a microcomputer. As shown in Fig. 3, the part data generating device 10 includes a storage unit 11, an operation unit 12, a display unit 13, and a control unit 14.

The storage unit 11 stores a component image G1 (see FIG. 5, etc.). The component image G1 is a two-dimensional image of a surface of the component that extends in the X-axis direction and the Y-axis direction opposite to the holding surface that is held by the suction nozzle 63. The types of components that are the subject of the image of the component image G1 include chip components with terminals provided on one end and the other end of the component body, transistors with emitter, base, and collector terminals, SOPs (Small Outline Packages), QFPs (Quad Flat Packages), PLCCs (Plastic Leaded Chip Carriers), and BGAs (Ball Grid Arrays). There are also components that do not have terminals on the component body.

Figure 5 shows a component image G1 corresponding to a component having multiple rows (two rows) of lead terminals in which multiple lead terminals are arranged in a specific arrangement direction relative to the component body. In this case, the component image G1 is an image that includes a component body region G11 corresponding to the component body, and each lead terminal region G12, G13 arranged in each of the multiple lead terminal rows.

The operation unit 12 is composed of a keyboard, mouse, etc., and accepts input operations by an operator regarding the generation of part data D2.

The display unit 13 is configured, for example, with a liquid crystal display, and displays various images, information, data, etc.

The control unit 14 is composed of a CPU, a ROM that stores a control program, a RAM used as a working area for the CPU, etc. The control unit 14 performs various calculation processes by the CPU executing the control program stored in the ROM, and controls the display operation of the display unit 13, etc. The control unit 14 includes, as its main functional components, a setting unit 141, a generating unit 142, a calculating unit 143, and a display control unit 144.

The display control unit 144 controls the display unit 13. The display control unit 144 controls the display unit 13 to switch between displaying the part type designation screen S1 shown in FIG. 4 and the data input screen S2 shown in FIGS. 5 to 19 based on an input operation by an operator via the operation unit 12.

When an operation to input a part type designation command for designating a type of part is performed via the operation unit 12, the display control unit 144 controls the display unit 13 to display the part type designation screen S1 shown in FIG. 4. The part type designation screen S1 has a part information input area AR10, a part type information input area AR20, and a screen switching input area AR25 that can be input via the operation unit 12.

The part information input area AR10 is divided into an area for inputting part information J1 such as a part name for identifying a part, an area for inputting set position information J2 indicating the set position in the part supply unit 4 of the feeder 5 that supplies the part, and an area for inputting feeder information J3 for identifying the feeder 5 that supplies the part. The part type information input area AR20 displays a plurality of part type information J4 indicating the type of part. The operator can input a part type designation command for designating the type of part by selecting one piece of part type information J4 from the plurality of part type information J4 displayed in the part type information input area AR20. The screen switching input area AR25 is operated when switching the screen of the display unit 13 from the part type designation screen S1 to the data input screen S2.

When a data input operation for inputting parameter data related to the features of the parts that make up the part data D2 is performed via the operation unit 12, the display control unit 144 controls the display unit 13 to display the data input screen S2 shown in Figures 5 to 19. The data input screen S2 has an image read command area AR30, a first image display area AR40, a data input area AR50, a display switch command area AR60, magnification change command areas AR61 and AR62, a position change command area AR70, a display target change command area AR80, an input end command area AR90, and a cancel command area AR91 set therein.

The image read command area AR30 on the data input screen S2 is an area where input operations can be performed via the operation unit 12, and is operated when inputting an instruction to display the part image G1 stored in the memory unit 11 in the first image display area AR40. The first image display area AR40 is an area where various images including the part image G1 are displayed.

Data input area AR50 on data input screen S2 is an area where input operations can be performed via operation unit 12. Data input operations for inputting each piece of data constituting part data D2 are performed via operation unit 12, targeting data input area AR50 on data input screen S2. Data input area AR50 is partitioned into an area portion that displays multiple parameters J5 related to the characteristics of the part, and a data input field J6 for inputting data corresponding to each parameter J5. Each piece of data constituting part data D2 is input into data input field J6 so as to correspond to each parameter J5.

As shown in FIG. 5, the parameters J5 related to the part characteristics include basic parameters J51 and focus parameters J52.

The basic parameters J51 are parameters that indicate the basic characteristics of a part. The basic parameters J51 include, for example, an outer dimension X1 that indicates the outer dimension of the part in the X-axis direction, an outer dimension Y1 that indicates the outer dimension of the part in the Y-axis direction, and a part thickness that indicates the thickness of the part.

The focus parameter J52 is a parameter indicating the feature of the part to be noted when creating the part data D2. For example, a parameter indicating the feature related to the terminal of the part is adopted as the focus parameter J52. As in the example of FIG. 5, when the part corresponding to the part image G1 displayed in the first image display area AR40 is a part having lead terminal rows at one end and the other end in the X-axis direction of the part body, the focus parameter J52 has the number of leads E, lead pitch E1, lead width E2, lead length E3, and reference terminal position E4 for the lead terminal row on one end side, and the number of leads W, lead pitch W1, lead width W2, lead length W3, and reference terminal position W4 for the lead terminal row on the other end side. The number of leads E and W indicate the number of lead terminals arranged in each lead terminal row. The lead pitches E1 and W1 indicate the pitch dimension between the lead terminals arranged in each lead terminal row. The lead widths E2 and W2 indicate the width dimension of the lead terminals arranged in each lead terminal row. Lead lengths E3 and W3 indicate the length dimensions of the lead terminals arranged in each lead terminal row. Reference terminal positions E4 and W4 indicate the distance along the Y-axis from the center of the component to the position of the reference lead terminal (reference lead terminal) in each lead terminal row.

In the data input screen S2 of the display unit 13, the part image G1 is displayed so that the center of the part image G1 is located at the center position of the first image display area AR40. In this state, as shown in FIG. 6, when a data input operation for inputting data of the basic parameter J51 into the data input field J6 of the data input area AR50 is performed via the operation unit 12, the generation unit 142 generates a rectangular outline graphic G21 corresponding to the outermost peripheral edge of the part image G1 as the graphic image G2 of the part based on the input data corresponding to the basic parameter J51, and generates data corresponding to the basic parameter J51 from each data constituting the part data D2. In this case, the display control unit 144 controls the display unit 13 to display a superimposed image G3 in which the outline graphic G21 is superimposed on the part image G1 in the first image display area AR40. In this case, the superimposed image G3 is an image in which the rectangular outline graphic G21 is superimposed on the outermost peripheral edge of the part image G1.

7, when a data input operation for inputting data of the target parameter J52 into the data input field J6 of the data input area AR50 is performed via the operation unit 12, the generation unit 142 generates each terminal graphic G22 corresponding to each lead terminal area G12, G13 of the component image G1 as a graphic image G2 of the component based on the input data corresponding to the target parameter J52, and generates data corresponding to the target parameter J52 from each data constituting the component data D2. In this case, the display control unit 144 controls the display unit 13 to display a superimposed image G3 in which each terminal graphic G22 is superimposed on the component image G1 in the first image display area AR40. In this case, the superimposed image G3 is an image in which a rectangular outline graphic G21 is superimposed on the outermost periphery of the component image G1, and each terminal graphic G22 is superimposed on each lead terminal area G12, G13 of the component image G1. That is, in the first image display area AR40 on the data input screen S2 of the display unit 13, a superimposed image G3 is displayed in which a graphic image G2 including an outline graphic G21 and each terminal graphic G22 is superimposed on a component image G1.

The display switching command area AR60 on the data entry screen S2 is an area where input operations can be performed via the operation unit 12. An operation to input an instruction to enlarge the multiple attention areas G3S (FIG. 7) in the superimposed image G3 displayed in the first image display area AR40 is performed via the operation unit 12, targeting the display switching command area AR60 on the data entry screen S2. When an instruction to enlarge the multiple attention areas G3S is input by operating the display switching command area AR60, as shown in FIG. 8, the display control unit 144 controls the display unit 13 to display each enlarged image G31 obtained by enlarging each of the multiple attention areas G3S in the superimposed image G3 on the same data entry screen S2. The display control unit 144 controls the display unit 13 to display each enlarged image G31 within the first image display area AR40 on the data entry screen S2.

As described above, in the part data generating device 10, when a data input operation for inputting data for each parameter J5 constituting the part data D2 is performed via the operation unit 12, the generation unit 142 generates a graphic image G2 of the part and the part data D2 based on the input data corresponding to the data input operation. Then, a superimposed image G3 in which the graphic image G2 is superimposed on the part image G1 is displayed on the display unit 13. At this time, when an operation for inputting a command to enlarge a plurality of attention areas G3S in the superimposed image G3 is performed via the operation unit 12, the display control unit 144 controls the display unit 13 to display each enlarged image G31 in which each of the plurality of attention areas G3S is enlarged on the same data input screen S2.

In this case, each enlarged image G31 of the multiple attention areas G3S in the superimposed image G3 is displayed on the same data input screen S2 of the display unit 13. The operator can accurately grasp the amount of deviation of the graphic image G2 relative to the part image G1 by checking each enlarged image G31 of the multiple attention areas G3S displayed on the display unit 13. Therefore, the operator can check whether the input data of the parameter J5 related to the characteristics of the part constituting the part data D2 is accurate. This makes it possible to create part data D2 with high accuracy. Moreover, since each enlarged image G31 of the multiple attention areas G3S in the superimposed image G3 is displayed by a single operation of inputting an enlargement display command, the number of operations to change the position of the target area of the enlargement display in the superimposed image G3 can be reduced. Therefore, the operator can efficiently create part data D2 while checking each enlarged image G31 displayed on the display unit 13.

Also, as shown in FIG. 9, each time a data input operation for each parameter J5 in the data input area AR50 on the data input screen S2 is performed via the operation unit 12, the generation unit 142 updates and generates the graphic image G2 and the part data D2. Then, the display control unit 144 controls the display unit 13 to display a superimposed image G3 in which the updated graphic image G2 is superimposed on the part image G1. At this time, the display control unit 144 controls the display unit 13 to display each enlarged image G31 obtained by enlarging each of the multiple attention areas G3S in the superimposed image G3 within the first image display area AR40 on the data input screen S2.

In this embodiment, each time a data input operation is performed to input data for the part parameters J5, the graphic image G2 is updated based on the input data corresponding to that data input operation. Then, a superimposed image G3 in which the updated graphic image G2 is superimposed on the part image G1 is displayed on the display unit 13. In this case, the operator can accurately grasp the amount of deviation of the graphic image G2 relative to the part image G1 each time a data input operation is performed. This makes it possible to efficiently create accurate part data that corresponds to a graphic image that matches the part image.

Here, the characteristic parameter J5 of a part differs depending on the type of part. Therefore, the position of the attention area G3S to be enlarged and displayed in the superimposed image G3 in order to create accurate part data D2 also differs depending on the type of part. Therefore, as shown in FIG. 3, the part data generation device 10 is equipped with a setting unit 141. When an operation to input a part type designation command into the part type information input area AR20 on the part type designation screen S1 in FIG. 4 is performed via the operation unit 12, the setting unit 141 sets the parameter J5 and the position of the attention area G3S depending on the type of part indicated by the part type designation command.

In this case, the generation unit 142 can generate an appropriate graphic image G2 corresponding to a different part image G1 for each type of part, based on the input data for the parameters J5 set according to the type of part. Furthermore, the display control unit 144 can display an enlarged image G31, which is an enlarged image of the attention area G3S set according to the type of part, in the first image display area AR40 on the data input screen S2 of the display unit 13. Therefore, by checking the enlarged image G31 of the attention area G3S according to the type of part, the operator can check whether the input data of the parameters J5 set according to the type of part is accurate. This makes it possible to create accurate part data D2 according to the type of part.

For a component with one terminal provided on the component body, the setting unit 141 sets one attention area G3S in the superimposed image G3 based on an area on the component image G1 that corresponds to the one terminal. For a chip component with terminals provided on one end and the other end of the component body, the setting unit 141 sets two attention areas G3S in the superimposed image G3 based on two areas on the component image G1 that correspond to each terminal.

In addition, in the case of a component having multiple terminal rows in which multiple terminals are arranged in a predetermined arrangement direction relative to the component body, the setting unit 141 sets each attention area G3S in the superimposed image G3 based on each area on the component image G1 corresponding to each terminal located at one end and the other end of the arrangement direction for each terminal row. Specifically, in the case of a component having terminal rows at one end and the other end of the X-axis direction of the component body, such as an SOP or a transistor, the setting unit 141 sets each attention area G3S in the superimposed image G3 based on each area on the component image G1 corresponding to each terminal located at one end and the other end of the arrangement direction (Y-axis direction) for each terminal row. In the case of a component such as a QFP or PLCC that has terminal rows at one end and the other end of the component body in the X-axis direction and terminal rows at one end and the other end of the component body in the Y-axis direction, the setting unit 141 sets each attention area G3S in the superimposed image G3 based on each terminal located at one end and the other end of the arrangement direction (Y-axis direction) of each terminal row at one end and the other end of the X-axis direction, and each terminal located at one end and the other end of the arrangement direction (X-axis direction) of each terminal row at one end and the other end of the Y-axis direction.

In addition, in the case of a component such as a BGA that has multiple ball terminals on the underside of the component body, the setting unit 141 sets each attention area G3S in the superimposed image G3 based on each area on the component image G1 that corresponds to each ball terminal located at the four corners of the component body.

In addition, in the case of a component that does not have terminals on the component body, the setting unit 141 sets each attention area G3S in the superimposed image G3 based on each area on the component image G1 that corresponds to the four corners of the component body.

As in the example of FIG. 5, when the component corresponding to the component image G1 displayed in the first image display area AR40 is a component having lead terminal rows at one and the other ends of the component body in the X-axis direction, the setting unit 141 sets the external dimension X1, external dimension Y1, and component thickness as basic parameters J51, and sets the number of leads E, W, lead pitch E1, W1, lead width E2, W2, lead length E3, W3, and reference terminal position E4, W4 for each lead terminal row as attention parameters J52. The setting unit 141 also sets multiple (four) attention areas G3S based on the areas on the component image G1 corresponding to each lead terminal located at one and the other ends of the arrangement direction (Y-axis direction) for each lead terminal row (see FIG. 7).

In this embodiment, when the part indicated by the part type designation command input to the operation unit 12 is a part having multiple lead terminal rows for the part body, when an enlarged display command is input in response to the operation of the display switching command area AR60 on the data input screen S2, four areas on the part image G1 corresponding to each lead terminal located at one end and the other end of the arrangement direction of each lead terminal row are set as attention areas G3S, and four enlarged images G31 are displayed in the first image display area AR40 on the data input screen S2 (see FIG. 8). In this case, the operator can check whether the input data for the number of leads E, W, lead pitch E1, W1, lead width E2, W2, lead length E3, W3, and reference terminal position E4, W4 for each lead terminal row set as the attention parameter J52 of the parameter J5 is accurate by checking each enlarged image G31 of the four attention areas G3S corresponding to each lead terminal located at one end and the other end of each lead terminal row. This allows the creation of accurate part data D2 according to the type of part.

Also, assume that, as shown in FIG. 8, in a state in which each enlarged image G31 is displayed in the first image display area AR40 on the data input screen S2, an operation to input a display switching command to switch the display form of the superimposed image G3 is performed in the display switching command area AR60. In this case, the display control unit 144 controls the display unit 13 so that the entire image (FIG. 7) showing the entire superimposed image G3 and each enlarged image G31 (FIG. 8) are switched and displayed in the first image display area AR40 in response to the display switching command. In this case, the operator can switch the display form of the superimposed image G3 in the first image display area AR40 on the data input screen S2 between a form that displays each enlarged image G31 and a form that displays the entire image by performing an operation to input a display switching command in the display switching command area AR60. Therefore, the operator can check whether each input data constituting the part data D2 is accurate by switching and checking the display of each enlarged image G31 and the entire image. This allows efficient creation of part data D2 with high accuracy.

10, the display control unit 144 may control the display unit 13 so that the entire image G32 showing the entire superimposed image G3 and each enlarged image G31 are displayed in one first image display area AR40 on the same data input screen S2. Also, as shown in FIG. 11, the display control unit 144 may control the display unit 13 so that the entire image G32 and each enlarged image G31 are displayed individually in the first image display area AR40 and the second image display area AR41, which are independent of each other, on the same data input screen S2. The display control unit 144 controls the display unit 13 so that each enlarged image G31 is displayed in the first image display area AR40, and the entire image G32 is displayed in the second image display area AR41. In either case, the entire image G32 showing the entire superimposed image G3 and each enlarged image G31 are displayed on the same data input screen S2 of the display unit 13. In this case, the operator can check whether each input data constituting the part data D2 is accurate by checking both the enlarged image G31 and the entire image G32. This allows for efficient creation of accurate part data D2.

When the entire image G32 and each enlarged image G31 are displayed on the display unit 13, as shown in Figs. 10 and 11, the display control unit 144 controls the display unit 13 so that an attention area marker frame G40, which marks the range of the multiple attention areas G3S on the entire image G32, is displayed superimposed on the entire image G32. In this case, the operator can easily confirm the target area of the enlarged display in the entire superimposed image G3 by using the attention area marker frame G40 as a mark.

In this embodiment, the display control unit 144 controls the display unit 13 so that each enlarged image G31 is displayed at a preset standard enlargement magnification within the first image display area AR40 on the data input screen S2. In this case, the operation by the operator to specify the enlargement magnification of each enlarged image G31 can be omitted.

However, as shown in FIG. 12, it is possible to change the magnification of each enlarged image G31 in the first image display area AR40. Specifically, magnification change command areas AR61 and AR62 are arranged on the data input screen S2 of the display unit 13. The magnification change command areas AR61 and AR62 are areas where input operations can be performed via the operation unit 12. An operation to input a magnification change command to change the magnification of each enlarged image G31 displayed in the first image display area AR40 from the standard magnification is performed via the operation unit 12 for the magnification change command areas AR61 and AR62. When a magnification change command is input by operating the magnification change command areas AR61 and AR62, the display control unit 144 controls the display unit 13 so that each enlarged image G31 is displayed in the first image display area AR40 at a magnification according to the magnification change command. In this case, the operator can check each enlarged image G31 at a magnification different from the standard magnification by performing an operation to input a magnification change command.

Also, as shown in FIG. 13, in a state where each enlarged image G31 obtained by enlarging a plurality of attention areas G3S set by the setting unit 141 is displayed in the first image display area AR40, it is possible to change the position of the enlarged display in the superimposed image G3. Specifically, a position change command area AR70 is arranged on the data input screen S2 of the display unit 13. The position change command area AR70 is an area where an input operation can be performed via the operation unit 12. An operation to input a position change command to change the position of the enlarged display in the superimposed image G3 is performed via the operation unit 12, targeting this position change command area AR70. When a position change command is input by operating the position change command area AR70, the display control unit 144 controls the display unit 13 to change the position of the enlarged display in accordance with the position change command. In this case, the operator can perform an operation to input a position change command to display the enlarged image G31 obtained by enlarging the desired position indicated by the position change command in the first image display area AR40 on the data input screen S2.

In this embodiment, the display control unit 144 controls the display unit 13 so that a maximum of four enlarged images G31 are displayed as the standard number of enlarged images in the first image display area AR40 on the same data entry screen S2. In this case, the size of each of the four enlarged images G31 in the first image display area AR40 on the data entry screen S2 can be prevented from becoming excessively small or excessively large. This allows the operator to accurately grasp the amount of deviation of the graphic image G2 relative to the part image G1 by checking each of the four enlarged images G31 displayed in the first image display area AR40 on the same data entry screen S2.

As described above, in the case of a component such as a QFP or a PLCC, the setting unit 141 sets each attention area G3S in the superimposed image G3 corresponding to each terminal located at one end and the other end of the arrangement direction (Y-axis direction) of each terminal row at one end and the other end of the X-axis direction of the component body, and each terminal located at one end and the other end of the arrangement direction (X-axis direction) of each terminal row at one end and the other end of the Y-axis direction of the component body. In this case, the number of attention areas G3S set by the setting unit 141 is eight.

Assuming such a case, as shown in FIG. 14 and FIG. 15, a display object change command area AR80 is arranged on the data input screen S2 of the display unit 13. The display object change command area AR80 is an area where an input operation can be performed via the operation unit 12. An operation to input a display object change command to change the target attention area G3S to be enlarged and displayed in the first image display area AR40 on the data input screen S2 is performed via the operation unit 12, with the display object change command area AR80 as the target. In the example of FIG. 14, enlarged images G31 of four attention areas G3S corresponding to each terminal located at one end and the other end of the arrangement direction (Y-axis direction) of each terminal row at one end and the other end of the X-axis direction of the component body are displayed in the first image display area AR40. In this state, when the display object change command area AR80 is operated, the target of the enlarged display is changed as in the example of FIG. 15. In the example of FIG. 15, enlarged images G31 of four focus areas G3S corresponding to the terminals located at one end and the other end of the arrangement direction (X-axis direction) of each terminal row in the Y-axis direction of the component body are displayed in the first image display area AR40.

When the number of attention areas G3S set by the setting unit 141 is greater than the maximum standard enlarged display number of "4", the display control unit 144 controls the display unit 13 so that each enlarged image G31 is displayed while changing the attention area G3S to be enlarged and displayed in the first image display area AR40 in response to a display target change command based on an operation of the display target change command area AR80. This allows the operator to check each enlarged image G31 of all attention areas G3S set by the setting unit 141 while changing the target of the enlarged display.

Also, as shown in FIG. 16, when the number of attention areas G3S set by the setting unit 141 is greater than the maximum value of the standard enlarged display number "4", the display control unit 144 may control the display unit 13 so that the number of enlarged images G31 of the attention areas G3S corresponding to a display number change command input via the operation unit 12 for changing the standard enlarged display number are displayed in the first image display area AR40 on the same data input screen S2. In this case, the operator can display each enlarged image G31 of all attention areas G3S set by the setting unit 141 in the first image display area AR40 on the same data input screen S2 by performing an operation to input a display number change command.

Next, assume that the part indicated by the part type designation command input to the part type information input area AR20 on the part type designation screen S1 in FIG. 4 is a part in which a terminal having a width of a predetermined value or more is provided on the part body. In this case, the setting unit 141 sets multiple attention areas G3S based on the area on the part image G1 corresponding to the corners of the terminal having a width of a predetermined value or more. In this case, as shown in FIG. 17, the display control unit 144 controls the display unit 13 so that each enlarged image G31 of the multiple attention areas G3S corresponding to the corners of the terminal set by the setting unit 141 is displayed in the first image display area AR40 on the data input screen S2. In this case, the operator can check whether the input data constituting the part data D2 is accurate by checking each enlarged image G31 of the attention area G3S corresponding to the corners of the terminal having a width of a predetermined value or more. This allows for the creation of accurate part data D2 according to the type of part.

Also, assume that the part indicated by the part type designation command input to the part type information input area AR20 on the part type designation screen S1 in FIG. 4 is a part that does not have a terminal on the part body. In this case, the setting unit 141 sets multiple attention areas G3S based on the areas on the part image G1 corresponding to the corners of the part body. In this case, as shown in FIG. 18, the display control unit 144 controls the display unit 13 so that each enlarged image G31 of the attention area G3S relating to the four corners of the rectangular outline graphic G21 corresponding to the corners of the part body set by the setting unit 141 is displayed in the first image display area AR40 on the data input screen S2. In this case, the operator can check whether the input data constituting the part data D2 is accurate by checking each enlarged image G31 of the attention area G3S corresponding to the corners of the part body. This allows for the creation of accurate part data D2 according to the type of part.

As shown in FIG. 19, an input end command area AR90 and a cancel command area AR91 are arranged on the data input screen S2 of the display unit 13. The input end command area AR90 and the cancel command area AR91 are areas where input operations can be performed via the operation unit 12. The input end command area AR90 is an area that is operated when terminating a data input operation for inputting each data of the parameter J5 into the data input field J6 of the data input area AR50 on the data input screen S2. On the other hand, the cancel command area AR91 is an area that is operated when canceling an operation to terminate the data input operation.

Assume that an input end command to end a data input operation based on an operation of the input end command area AR90 is input via the operation unit 12. In this case, the generation unit 142 determines the graphic image G2 and part data D2 based on the input data input in response to a data input operation in the data input area AR50 immediately before the input end command as the graphic image G2 and part data D2 for part recognition to be used during the part recognition process.

In the component mounter 1, a component recognition test is performed before the actual production of a component mounting board, using the component recognition graphic image G2 determined by the generation unit 142 to check whether the holding state of the component by the suction nozzle 63 can be accurately recognized using the component data D2 determined by the generation unit 142. In this component recognition test, the first imaging unit C1 acquires a component recognition component image G1 showing an image of the component held by the suction nozzle 63, just as in the production of an actual component mounting board. Then, the component recognition unit 95 of the component mounter 1 performs a component recognition process to recognize the holding state of the component held by the suction nozzle 63, based on the component recognition component image G1 and the component data D2 determined by the generation unit 142.

When part recognition processing is performed using part data D2 in such a part recognition test, the display control unit 144 of the part data generation device 10 controls the display unit 13 so that a superimposed image G3 for part recognition, in which the graphic image G2 for part recognition determined by the generation unit 142 is superimposed on the part image G1 for part recognition, is displayed in the first image display area AR40 on the data input screen S2 (see FIG. 19). In this case, by checking the superimposed image G3 for part recognition, the operator can check whether the holding state of the part by the suction nozzle 63 can be accurately recognized in the part recognition processing using part data D2.

At this time, as shown in FIG. 3, the part data generating device 10 includes a calculation unit 143. The calculation unit 143 calculates the amount of deviation of the graphic image G2 for part recognition relative to the part image G1 for part recognition in the superimposed image G3 for part recognition. Then, when an excess deviation area in which the amount of deviation between the part image G1 and the graphic image G2 exceeds a predetermined allowable threshold exists in the superimposed image G3 for part recognition, the calculation unit 143 outputs position data of the excess deviation area. In this case, as shown in FIG. 19, the display control unit 144 controls the display unit 13 so that an excess deviation mark frame G50, which marks the range of the excess deviation area on the superimposed image G3 for part recognition, is superimposed on the superimposed image G3 for part recognition and displayed. In this case, the operator can easily confirm the position of the excess deviation area in which the amount of deviation of the graphic image G2 for part recognition relative to the part image G1 for part recognition exceeds the allowable threshold using the excess deviation mark frame G50 as a mark. This allows the operator to correct the data of each parameter J5 that constitutes the part data D2 while checking the excessive deviation area in the superimposed image G3 for part recognition. This makes it possible to create more accurate part data D2.
