JP 2011-082500 A

The objective is to properly manage the feeder that supplies parts by sending out tape-shaped parts through the operation of a feeding device.

In order to solve the above-mentioned problems, this specification discloses a method for managing a feeder that supplies components by feeding out taped components through the operation of a feeding device, the method including: a first acquisition step of acquiring the drive position of the drive source of the feeding device when a taped component is attached to the feeder; a second acquisition step of acquiring the drive position of the drive source of the feeding device when the feeder with the taped component attached is attached to a substrate-related operation machine; and a determination step of determining whether or not a taped component needs to be replaced at the feeder based on the drive position acquired in the first acquisition step and the drive position acquired in the second acquisition step.

This specification also discloses a work system that includes a feeder that supplies components by feeding out taped components through the operation of a feeding device, an attachment device for attaching the taped components to the feeder, a substrate-related work machine that mounts the components supplied from the feeder onto a substrate, and a control device that determines whether or not taped components need to be replaced at the feeder based on the drive position of the drive source of the feeding device when the taped components are attached to the feeder in the attachment device, and the drive position of the drive source of the feeding device when the feeder with the taped components attached is attached to the substrate-related work machine.

In this disclosure, whether or not a tape component needs to be replaced at a feeder is determined based on the drive position of the drive source of the feeding device when a tape component is attached to the feeder and the drive position of the drive source of the feeding device when the feeder with the tape component attached is attached to a substrate-related operation machine. This makes it possible to appropriately manage feeders that supply components by operating the feeding device to feed out the tape component.

Below, an embodiment of the present invention will be described in detail with reference to the drawings as a form for implementing the present invention.

Figure 1 shows an electronic component mounting device 10. The electronic component mounting device 10 comprises a mounting machine main body 20, a conveying device 22, a mounting head moving device (hereinafter abbreviated as "moving device") 24, a mounting head 26, a supply device 28, and a control device (see Figure 3) 30. The mounting machine main body 20 is composed of a frame 32 and a beam 34 suspended from the frame 32.

The transport device 22 includes two conveyor devices 40, 42. These two conveyor devices 40, 42 are arranged on the frame 32 so that they are parallel to each other and extend in a predetermined direction. The direction in which the conveyor devices 40, 42 extend is referred to as the X-axis direction, and the horizontal direction perpendicular to that direction is referred to as the Y-axis direction. Each of the two conveyor devices 40, 42 transports a circuit board supported by each conveyor device 40, 42 in the X-axis direction by an electromagnetic motor (see Figure 3) 46. The circuit board is held in a predetermined position by a board holding device (see Figure 3) 48.

The moving device 24 is an XY robot type moving device. The moving device 24 is equipped with an electromagnetic motor (see Figure 3) 52 that slides the slider 50 in the X-axis direction, and an electromagnetic motor (see Figure 3) 54 that slides it in the Y-axis direction. A mounting head 26 is attached to the slider 50, and the mounting head 26 is moved to any position on the frame 32 by the operation of the two electromagnetic motors 52, 54.

The mounting head 26 mounts electronic components on circuit boards. The mounting head 26 has a suction nozzle 60 attached to its bottom surface. The suction nozzle 60 is connected to a positive/negative pressure supply device (see Figure 3) 62 via negative pressure air and positive pressure air passages. The suction nozzle 60 uses negative pressure to suction and hold electronic components, and releases the held electronic components using positive pressure. The mounting head 26 also has a nozzle lifting device (see Figure 3) 64 that raises and lowers the suction nozzle 60. The nozzle lifting device 64 allows the mounting head 26 to change the vertical position of the electronic component it is holding.

The supply device 28 is disposed at the front end of the frame 32 and has multiple tape feeders 70. As shown in FIG. 2, each tape feeder 70 has a reel 72, a delivery device 74, and a peeling device 76, and supplies electronic components at the end of the top surface. Specifically, a tape component 78 is wound around the reel 72, and the reel 72 around which the tape component 78 is wound is stored in a reel storage section 79. The tape component 78 is then pulled out from the reel 72 stored in the reel storage section 79 onto a tape guide 80. The tape component 78 is formed by taping electronic components and has feed holes (not shown) formed at a predetermined pitch. A sprocket 82 of the delivery device 74 engages with the feed holes. The sprocket 82 is rotated by an electromagnetic motor 84. This structure allows the tape component 78 to be delivered toward the supply position. An encoder 85 (see FIG. 3) is provided on the electromagnetic motor 84. The encoder 85 detects the drive position, i.e., the rotation angle, of the electromagnetic motor 84, which is the drive source of the delivery device 74, and the operation of the electromagnetic motor 84 is controlled based on the value detected by the encoder 85. The encoder 85 is an absolute encoder and detects the absolute rotation angle of the electromagnetic motor. In other words, an origin is set in the encoder 85, and the rotation angle from the origin is detected. Therefore, as long as the electromagnetic motor 84 does not rotate, the rotation angle detected by the encoder 85 does not change even after the power supply to the electromagnetic motor is cut off.

The peeling device 76 also includes a film peeling mechanism 86 and a gear mechanism 88. The film peeling mechanism 86 is a mechanism for peeling the top film 90 from the tape-formed component 78 and is disposed in front of an opening 92 formed at the top end of the tape feeder 70. The gear mechanism 88 is a mechanism for pulling the top film 90 peeled from the tape-formed component 78 into a film recovery section 94. With this structure, when the top film 90 is peeled from the tape-formed component 78, the electronic components housed in the tape-formed component 78 are exposed at the opening 92, and the exposed electronic components are suction-held by the suction nozzle 60 of the mounting head 26. In other words, the opening 92 serves as the electronic component supply position for the tape feeder 70. A tape guide passage 96 is formed on the side of the opening 92 facing the feed direction of the tape-formed component 78, extending downward. Through this tape guide passage 96, the waste tape 98 from which the electronic components have been removed from the tape-formed component 78 is discharged.

A connector 100 is disposed on the side of the tape feeder 70 in the feed direction of the tape component 78. Meanwhile, as shown in FIG. 1, a tape feeder mounting base 110 is disposed at the front end of the frame 32. The tape feeder mounting base 110 is composed of an erected surface 112 that stands perpendicular to the frame 32 and a protruding surface 114 that protrudes from the lower end of the erected surface 112. A plurality of slide grooves 116 are formed in the protruding surface 114 so as to extend in the Y direction, and the erected surface 112 is provided with connector connection portions 118 corresponding to each of the plurality of slide grooves 116. The lower end of the tape feeder 70 is fitted into the slide grooves 116, and the connector 100 of the tape feeder 70 is connected to the connector connection portion 118. As a result, the tape feeder 70 is positioned and mounted on the tape feeder mounting base 110, and is electrically connected.

As shown in FIG. 3, the control device 30 includes a controller 130, multiple drive circuits 132, a control circuit 133, and a memory 134. The multiple drive circuits 132 are connected to the electromagnetic motors 46, 52, 54, and 84, the substrate holding device 48, and the positive and negative pressure supply device 62. The controller 130 is primarily a computer, including a CPU, ROM, RAM, etc., and is connected to the multiple drive circuits 132. This allows the controller 130 to control the operation of the conveying device 22, moving device 24, etc. The controller 130 is also connected to the encoder 85 of the tape feeder 70, and controls the operation of the electromagnetic motor 84 of the tape feeder 70, i.e., the feeding device 74, based on the detection value of the encoder 85. The controller 130 is also connected to a display device 136 via the control circuit 133. This allows the controller 130 to display any image on the display device 136. The controller 130 is also connected to the memory 134. This allows the controller 130 to store various pieces of information in the memory 134 and acquire various pieces of information from the memory 134 .

In the electronic component mounting device 10, with the above-described configuration, the mounting head 26 performs mounting work on the circuit board held by the transport device 22. Specifically, the circuit board is transported to the work position in response to a command from the controller 130, where it is fixedly held by the board holding device 48. The tape feeder 70 also feeds taped components in response to a command from the controller 130, and supplies electronic components at the supply position. The mounting head 26 then moves to a position above the electronic component supply position in response to a command from the controller 130, and sucks and holds the electronic component with the suction nozzle 60. The mounting head 26 then moves above the circuit board and mounts the electronic component on the circuit board.

In this way, in the electronic component mounting device 10, electronic components supplied by the tape feeder 70 are mounted on the circuit board. For this reason, it is necessary to properly manage the type of electronic components supplied by the tape feeder 70 and the identification information for identifying that tape feeder 70. In other words, it is necessary to properly manage the type of electronic component tape wound on the reel 72 contained in the tape feeder 70 and the identification information for the tape feeder. For this reason, when the reel 72 is contained in the tape feeder 70, the registration information for the electronic component is registered.

Specifically, when taped components are attached to the tape feeder 70 using the loading device 150 shown in FIG. 4, the registration information for the electronic components is registered. The loading device 150 is composed of a kitting stand 152 and a control device 154. The kitting stand 152 has a mounting base 160, a stand 162, and an upper rail 164. The mounting base 160 supports the bottom of the tape feeder, and the bottom of the tape feeder is placed on the upper surface of the mounting base 160. The stand 162 is erected on the upper surface of the mounting base 160 and supports the side of the tape feeder placed on the mounting base 160. An upper rail 164 is disposed at the upper end of the stand 162, and the upper end surface of the tape feeder placed on the mounting base 160 fits into the upper rail 164. The tape feeder is set in the kitting stand 152 in this position. Additionally, a bracket 166 is fixed to the front side edge of stand 162 so as to cover the front side wall of the tape feeder set in kitting stand 152, and a connector connection part 168 is disposed on bracket 166. Therefore, when the tape feeder is set in kitting stand 152, connector 100 of the tape feeder is connected to connector connection part 168. As a result, tape feeder 70 is set in a positioned state on kitting stand 152 and is electrically connected.

The control device 154 is connected to the connector connection portion 168 of the kitting stand 152 and controls the operation of the tape feeder set on the kitting stand 152. The control device 154 is equipped with a controller 170 and a drive circuit 172. The controller 170 is primarily a computer equipped with a CPU, ROM, RAM, etc., and is connected to the drive circuit 172. When a tape feeder is set on the kitting stand 152, the drive circuit 172 is connected to the electromagnetic motor 84 of that tape feeder. When a tape feeder is set on the kitting stand 152, the controller 170 is also connected to the encoder 85 of that tape feeder. As a result, the controller 170 controls the operation of the electromagnetic motor 84 of the tape feeder 70, i.e., the feeding device 74, based on the detection value of the encoder 85. A code reader 176 is also connected to the controller 170. The control device 154 is connected to the control device 30 of the electronic component mounting device 10, and various information is transmitted and received between the control device 154 and the control device 30.

In a loading device 150 with this structure, when a taped component is attached to the tape feeder 70, the registration information for the electronic component is registered. More specifically, a barcode is affixed to the reel 72 on which the taped component is wound. This barcode encodes component information indicating the type of electronic component stored in the taped component wound on the reel 72. An operator then reads the barcode of the reel 72 to be stored in the tape feeder using the code reader 176. This allows the controller 170 to obtain component information for the taped component wound on the reel 72.

The worker also reads the barcode on the reel 72 using the code reader 176, stores the reel 72 in the reel storage section 79 of the tape feeder, and sets the tape feeder on the kitting stand 152. This electrically connects the tape feeder to the control device 154. At this time, the controller 170 acquires the tape feeder's identification information from the tape feeder. The controller 170 then transmits the component information read by the code reader 176 and the tape feeder's identification information acquired from the tape feeder to the control device 30 of the electronic component mounting device 10. As a result, when the control device 30 receives the component information and the tape feeder's identification information, it associates the received component information with the tape feeder's identification information and stores them in memory 134 as registration information for the electronic component.

After setting the tape feeder in the kitting stand 152, the worker pulls out the leading end of the tape component from the reel 72 stored in the tape feeder and feeds it along the top surface of the tape guide 80. The worker feeds the tape component until the feed hole at the leading end engages with the sprocket 82 of the feed device 74. Once the worker has fed the tape component until the feed hole engages with the sprocket 82 of the feed device 74, the worker operates an operation button (not shown) disposed on the stand 162. The operation button activates the electromagnetic motor 84 of the tape feeder while being operated. Operating the operation button activates the electromagnetic motor 84, which feeds the tape component engaged with the sprocket 82 toward the feed position. Therefore, the worker operates the operation button while checking which tape component is engaged with the sprocket 82. When the leading end of the tape component is fed to a predetermined position, for example, the feed position, the worker stops operating the operation button. As a result, the taped components are attached to the tape feeder 70 by the loading device 150. When the taped components are attached to the tape feeder 70 using the loading device 150, the component information and the tape feeder identification information are associated with each other and stored in the memory 134 in the control device 30 of the electronic component mounting apparatus 10, thereby registering the registration information of the electronic components. When the taped components are attached to the tape feeder, not only is the taped components fed out by the electromagnetic motor 84, but the top film peeled from the taped components is also set in the film peeling mechanism 86, and so forth; however, a description of the top film setting operation will be omitted.

In this way, when a tape-mounted component is attached to a tape feeder, the tape feeder is mounted on the tape feeder mounting table 110 of the electronic component mounting apparatus 10, and electronic components are supplied from the tape-mounted component attached to the tape feeder, thereby performing the component mounting operation. Therefore, when the tape feeder is mounted on the tape feeder mounting table 110 of the electronic component mounting apparatus 10, a verification operation for the electronic components is performed. More specifically, when the tape feeder is mounted on the tape feeder mounting table 110, the tape feeder is electrically connected to the control device 30 of the electronic component mounting apparatus 10. At this time, the controller 130 of the control device 30 acquires tape feeder identification information from the tape feeder. The controller 130 then extracts the identification information of the tape feeder mounted on the tape feeder mounting table 110 from the tape feeder identification information stored in memory 134. The controller 130 then identifies the component information stored in memory 134 in association with the extracted tape feeder identification information. The controller 130 then checks whether the type of electronic component indicated by the identified component information matches the type of electronic component to be mounted in the mounting operation by the electronic component mounting apparatus 10, i.e., performs an electronic component verification operation. If the type of electronic component indicated by the component information matches the type of electronic component to be mounted in the mounting operation by the electronic component mounting apparatus 10, the mounting operation by the electronic component mounting apparatus 10 is performed. This ensures that the components are mounted appropriately. In this way, the electronic component mounting apparatus 10 performs a verification operation of the electronic components on the tape feeders mounted on the tape feeder mounting table 110.

However, if a tape feeder is attached to the tape feeder mounting base 110 immediately after a tape component is attached to the tape feeder using the kitting stand 152, it is unlikely that the reel has been replaced. On the other hand, if a certain amount of time has passed since a tape component was attached to the tape feeder using the kitting stand 152 and the tape feeder is then attached to the tape feeder mounting base 110, it is highly likely that the reel has been replaced. In other words, it is highly likely that the reel has been replaced after the registration information for the electronic component was registered. In this way, if a reel is replaced after the registration information for the electronic component has been registered and the tape feeder with the replaced reel is attached to the tape feeder mounting base 110, the verification process cannot be performed properly.

For this reason, in conventional methods, if a predetermined time has passed since the registration information for an electronic component was registered, the registration information is erased. Therefore, if a predetermined time has passed since the registration information for an electronic component was registered, the registration information for the electronic component is re-registered, and then the electronic component verification process is performed. In this way, performing the electronic component verification process after the registration information for the electronic component is re-registered ensures proper verification. However, re-registering the registration information for electronic components places a burden on workers. In particular, in cases where tape feeders are stored after tape components are attached to them in the kitting stand 152, it is necessary to re-register the registration information for electronic components for many tape feeders, which places a significant burden on workers. Furthermore, there is a risk that some workers will avoid re-registering the registration information for electronic components and not perform the verification process at all.

In light of this, the electronic component mounting device 10 performs a verification operation without erasing the registration information for the electronic component, even if a predetermined time has passed since the registration information was registered. However, to ensure proper verification, the presence or absence of a reel replacement is determined based on the detection value from the tape feeder's encoder.

More specifically, as described above, when a tape component is attached to a tape feeder in the kitting stand 152, the control device 154 transmits component information and tape feeder identification information to the control device 30, which then stores the component information and tape feeder identification information in memory 134 as registration information. At this time, the control device 154 transmits not only the component information and tape feeder identification information to the control device 30, but also the detection value of the encoder 85 when the tape component is attached to the tape feeder. Specifically, the control device 154 acquires the detection value of the encoder 85 when attachment of the tape component to the tape feeder is complete (hereinafter referred to as the "detection value at component attachment"). In other words, once attachment of the tape component to the tape feeder is complete, the electromagnetic motor 84 is not operated, and therefore the control device 154 acquires the detection value of the encoder 85 after attachment of the tape component to the tape feeder is complete. Then, the control device 154 transmits the acquired detection values of the encoder 85, that is, the component installation detection values, the component information, and the tape feeder identification information, to the control device 30. Then, the control device 30 associates the component installation detection values, the component information, and the tape feeder identification information and stores them in the memory 134. As a result, the component installation detection values, the component information, and the tape feeder identification information are registered as registered information. This registered information is not erased even after a predetermined time has passed.

Furthermore, when a tape feeder is mounted on the tape feeder mounting stand 110 of the electronic component mounting device 10 and electrically connected to the control device 30 of the electronic component mounting device 10, the controller 130 of the control device 30 acquires the tape feeder's identification information from the tape feeder. Furthermore, the controller 130 acquires the detection value of the encoder 85 (hereinafter referred to as the "mounting detection value") from the tape feeder. The controller 130 then extracts the identification information of the tape feeder mounted on the tape feeder mounting stand 110 from the tape feeder identification information stored in memory 134. The controller 130 then identifies the component mounting detection value stored in memory 134 in association with the extracted tape feeder identification information. The controller 130 then compares the component mounting detection value stored in memory 134 with the mounting detection value acquired from the tape feeder mounted on the tape feeder mounting stand 110. As described above, the encoder 85 is an absolute encoder, so unless the electromagnetic motor 84 rotates, the rotation angle detected by the encoder 85 does not change, even after the power supply to the electromagnetic motor is cut off. Therefore, if the component installation detection value and the mounting detection value are the same, it is presumed that the electromagnetic motor 84 is not operating. Furthermore, if the reel 72 in the tape feeder is replaced, the tape-formed components on the replaced reel 72 must be mounted in the tape feeder, and the electromagnetic motor 84 operates when the tape-formed components are fed out. In other words, if the component installation detection value and the mounting detection value are the same, it is presumed that the reel 72 in the tape feeder has not been replaced. On the other hand, if the component installation detection value and the mounting detection value are different, it is presumed that the reel 72 in the tape feeder has been replaced.

Therefore, if the component installation detection value and the mounting detection value are the same, the controller 130 performs a verification operation. That is, the controller 130 identifies the component information stored in memory 134 by correlating it with the tape feeder identification information extracted from the tape feeder identification information stored in memory 134. The controller 130 then confirms whether the type of electronic component indicated by the identified component information matches the type of electronic component to be mounted in the mounting operation on the electronic component mounting device 10, i.e., performs an electronic component verification operation. In this way, by performing the verification operation when the component installation detection value and the mounting detection value are the same, i.e., when it is estimated that the reel 72 has not been replaced in the tape feeder, it is possible to ensure that the verification operation is performed appropriately.

On the other hand, if the detected value at component installation differs from the detected value at mounting, it is assumed that the reel 72 has been replaced in the tape feeder, and the controller 130 displays a warning screen on the display device 136. This warning screen displays a comment urging the user to re-register component information because the reel has been replaced in the tape feeder mounted on the tape feeder mounting base 110. This makes it possible to prevent the supply of electronic components from a reel 72 that has been replaced after the component information was registered, ensuring proper component mounting work.

As shown in FIG. 3, the controller 130 of the control device 30 has a first acquisition unit 180, a second acquisition unit 182, and a judgment unit 184. The first acquisition unit 180 is a functional unit for acquiring, via the kitting stand 152, the detection value of the encoder 85 when a tape component is attached to the tape feeder. The second acquisition unit 182 is a functional unit for acquiring, via the electronic component mounting device 10, the detection value of the encoder 85 when the tape feeder with the tape component attached is attached to the tape feeder mounting table 110. The judgment unit 184 is a functional unit for determining whether or not the reel 72 in the tape feeder needs to be replaced based on the detection value at component attachment and the detection value at mounting.

In addition, while in the first embodiment described above, whether or not the reel needs to be replaced is determined based on the detection value of the encoder 85 of the feeding device 74 in the tape feeder, in the second embodiment, whether or not the reel needs to be replaced is determined based on the opening and closing of the reel cover in the tape feeder. Specifically, in the second embodiment, the tape feeder 200 shown in Figure 5 is used. Since the tape feeder 200 has almost the same structure as the tape feeder 70 in the first embodiment, except for the reel cover 202, a description of the configuration other than the reel cover 202 will be omitted, and the same reference numerals as the configuration of the tape feeder 70 will be used.

A reel storage section 79 that opens to the side is formed in the housing 206 of the tape feeder 200. The reel cover 202 is generally flat and is arranged to cover the opening of the reel storage section 79 to the side of the housing 206. The reel cover 202 is supported at its upper end by a pair of hinges 208 so that it can swing. As a result, swinging the reel cover 202 downward closes the reel cover 202 and covers the reel storage section 79. On the other hand, as shown in FIG. 6 , swinging the reel cover 202 upward opens the reel cover 202, exposing the reel storage section 79. Therefore, when a reel 72 is stored in the reel storage section 79, opening the reel cover 202 allows the reel 72 to be removed from the reel storage section 79. Furthermore, when the reel 72 is not stored in the reel storage section 79, the reel cover 202 can be opened to store the reel 72 in the reel storage section 79. When the tape feeder 200 in which the reel 72 is stored is used, the reel cover 202 is closed. Therefore, when replacing the reel 72, the reel cover 202 is always opened and closed.

The tape feeder 200 also incorporates a detection sensor 210 that detects whether the reel cover 202 is open or closed, and a memory 212 that stores the detection results from the detection sensor 210. The tape feeder 200 also incorporates a battery 214 that supplies power to the detection sensor 210 and the memory 212. As a result, even if the reel cover 202 is opened or closed in an unpowered tape feeder 200, the opening or closing of the reel cover 202 is detected by the detection sensor 210, and the detection results from the detection sensor 210 are stored in the memory 212. In the memory 212, an opening or closing flag is set to ON when the opening or closing of the reel cover 202 is detected by the detection sensor 210 and the detection results from the detection sensor 210 are stored in the memory 212, and the opening or closing flag is set to OFF when the opening or closing of the reel cover 202 is not detected by the detection sensor 210.

When tape components are attached to a tape feeder 200 configured as described above using the kitting stand 152, the reel cover 202 may be opened or closed. In such cases, the detection sensor 210 detects whether the reel cover 202 is open or closed, and the detection result is stored in memory 212. That is, an open/close flag is set ON in memory 212. When the tape feeder 200 is set in the kitting stand 152 and the barcode affixed to the reel is read by the code reader 176, the control device 154 transmits component information and identification information for the tape feeder 200 to the control device 30. This causes the electronic component registration information to be registered in the control device 30. After transmitting the component information and identification information for the tape feeder 200 to the control device 30, the control device 154 then outputs a command to erase the memory 212 to the tape feeder 200. This erases the detection results from the detection sensor 210 stored in memory 212. In other words, after the registration information of the electronic component is registered, the open/close flag in memory 212 is turned OFF. Therefore, the open/close flag in memory 212 is maintained OFF unless the reel cover 202 of the tape feeder 200 is opened or closed after the registration information of the electronic component is registered. On the other hand, if the reel cover 202 of the tape feeder 200 is opened or closed even once after the registration information of the electronic component is registered, the open/close flag in memory 212 is turned ON.

When the tape feeder 200 is attached to the tape feeder attachment table 110 to be used in a mounting operation on the electronic component mounting device 10, the controller 130 of the control device 30 acquires identification information from the tape feeder 200. At this time, the controller 130 acquires not only the identification information from the tape feeder 200 but also information stored in the memory 212, i.e., information indicating whether the open/close flag is ON or OFF. If the open/close flag is OFF, it is assumed that the reel cover 202 of the tape feeder 200 has never been opened or closed since the registration information of the electronic component was registered, and therefore the reel 72 has not been replaced in the tape feeder. Therefore, if the open/close flag is OFF, the verification operation is performed according to the procedure described above. On the other hand, if the open/close flag is ON, it is assumed that the reel cover 202 of the tape feeder 200 has been opened and closed since the registration information of the electronic component was registered, and therefore the reel 72 has been replaced in the tape feeder. Therefore, when the open/close flag is ON, the warning screen described above is displayed on the display device 136. As a result, the second embodiment can also achieve the same effects as the first embodiment.
