Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for inputting an electronic component insertion position in an electronic component automatic insertion machine that automatically inserts various electronic components into a printed circuit board.

[Prior art]

Fixed resistor, capacitor, I supplied from the component supply device
Various electronic components such as C are gripped by the insertion head, and the printed circuit board (hereinafter also simply referred to as "the circuit board") is rotated according to the insertion direction, and automatically at the specified insertion position on the circuit board. There is an automatic electronic component insertion machine for inserting.

A component insertion program for each board by such an electronic component automatic insertion machine is usually created by a programmer based on the drawing of the board or a dedicated program using the board itself by a creation machine, and a direct keyboard is used. Or using punch tape, magnetic tape, or the like.

Also, since it is uneconomical to have a dedicated program maker separately, by providing the electronic component automatic insertion machine itself with a program maker function and teaching the insertion position and the insertion direction of each component with respect to the board, Creating an insertion program is also under way.

[Problems to be solved by the invention]

However, in the input method of the conventional component insertion device in such an electronic component automatic insertion machine, the insertion head or the table on which the board is mounted may have to be rotated depending on the insertion direction of the component, and the operation is troublesome. It was

Further, even when the board is fixed, for example, when the insertion position of the IC component S with respect to the board P is input as shown in FIG. 1, conventionally, the IC component S is always at a diagonal position as shown in FIG. Two pin insertion holes (shown by black dots) are detected, or one insertion hole at a different position from the board depending on the insertion direction of the IC component as shown in FIG. In the example, the insertion holes at the lower left end are detected when the IC component insertion directions are 0 ° and 180 °, and at the lower right end when they are 90 ° and 270 °.

As described above, it takes time to input the positions of the two lead wire insertion holes for each part, and the down time of the machine becomes long, resulting in poor productivity.

In addition, inputting the insertion holes at different positions depending on the insertion direction of the component is confusing, and thus a mistake easily occurs.

The present invention solves such a conventional problem, and for each component to be inserted into the substrate, for example, as shown in FIG. 1 (A), with respect to the substrate P regardless of the insertion direction of the component S. By inputting only one specific lead wire insertion hole that is uniquely determined (insertion hole positions a to d at the lower left end closest to the black dot O of the board in the illustrated example), it is easy to make mistakes and in a short time. The purpose is to enable input of a component insertion position.

[Means for solving problems]

In order to achieve this object, a method of inputting a component insertion position of an electronic component insertion machine according to the present invention is such that an electronic component supplied from a component supply device is gripped by an insertion head and a printed circuit board is rotated according to an insertion direction. In the automatic electronic component insertion machine that automatically inserts into the printed circuit board, the coordinates of the specific lead wire insertion hole that is uniquely determined only for the printed circuit board, regardless of the insertion direction, for each component to be inserted into the printed circuit board. Enter only one position, separately enter the component data and insertion direction data of each component to be inserted into the printed circuit board, and the coordinate data of the specific lead wire insertion hole and the coordinate position separately input to the above board. The coordinates of the center of the insertion head on the printed circuit board are calculated from the part data of the part to be inserted into the board and the data of the insertion direction. Is a method of inputting the component insertion device by calculating the rotation angle of the printed circuit board at the time of component insertion and the positioning coordinates of the printed circuit board after the rotation from the data and sequentially storing them.

Therefore, when the rotary actuator 80 rotates, the toothed belt 82, the pinion gear 77,
The slide member 73 and the optical sensor 75 held by the slide member 73 are moved to the solid line position or the phantom line position via the rack 76 and the like.

A light shielding plate 83 is attached to the slide member 73, and when the light shielding plate 83 is detected by the forward end detection sensor 84 or the backward end detection sensor 85, the rotation of the rotary reactor 80 is stopped.

By these, the optical sensor support moving device 70 is configured.

When the optical sensor 75 is moved to the position shown by the solid line by the optical sensor supporting and moving device 70, the turret board 54 of the lower turret 16 and the turret board 54 of the lower turret 16 are rotated at the same time as the 1/2 pitch rotation of the turret base 50 of the above-mentioned upper turret 15.

In this way, when the insertion hole of the substrate P is detected, the light source 65 and the optical sensor 75 can be positioned and detected at the same positions as the insertion head 51 and the clinch head 53 at the time of component insertion.

Here, an example of the optical sensor circuit for accurately detecting the configuration of the optical sensor 75 and the position of the insertion hole is shown in FIG.

The optical sensor 75 is configured by arranging photoelectric elements 75a to 75d, such as phototransistors or photodiodes, having uniform characteristics in respective parts obtained by dividing the light receiving surface into four parts symmetrically with respect to the center of the light receiving surface.

Then, the xx line and the yy line in the figure are attached so as to coincide with the X direction and the Y direction in FIG. Note that well-known circuits such as a bias applying circuit and a detection signal amplifying circuit for each photoelectric element are not shown.

The optical sensor circuit 90 includes photoelectric devices 75a and 75b of the optical sensor 75.
The detection signal from the photoelectric elements 75c and 75d is added by the addition circuit 86, the detection signal by the photoelectric elements 75a and 75b is added by the addition circuit 88, and the detection signals by the photoelectric elements 75b and 75c are added by the addition circuit 89. Add each.

Further, the difference detector 91 obtains the difference between the output signals of the adder circuits 86 and 87, so that the signal (0, +) indicating the direction and magnitude of coincidence (pass range) or deviation in the X direction with respect to the insertion hole H is obtained. , −) Is obtained. Similarly, the difference detector 92 obtains the difference between the signals output from the adder circuits 88 and 89 to obtain a signal (0) indicating the direction and magnitude of coincidence (passing range) or deviation in the Y direction with respect to the insertion hole H. , +,-) Is obtained.

When it is considered that the brightness of the light source 65 varies, the difference between the output signals from the difference detectors 91 and 92 is divided by the total amount of light received by the photoelectric elements 75a and 75d, and a signal indicating the magnitude of the deviation is further obtained. Be accurate.

Therefore, the board P of FIG. 6 is moved so that the specified insertion hole to be taught, that is, the lead wire insertion hole closest to the coordinate origin of the printed board is illuminated by the light source 65, If the output signals of the difference detectors 91 and 92 in FIG. 7 are both set to 0, the center of the insertion hole H and the center of the light-receiving surface of the optical sensor 75 coincide with each other. The position (XY coordinate) can be accurately detected by reading the distance in the X and Y directions from the origin.

Next, with reference to FIG. 8, the structure of the control section related to the present invention in this electronic component automatic insertion machine and the operation during teaching will be described.

This control unit consists of four operation keys on the operation panel shown in FIG.
A signal from the manual control means 18 including 8b and an X-direction control circuit 100 for inputting signals in the X-direction from the optical sensor circuit 90 of the insertion hole detection means shown in FIG. The Y direction control circuit 200, a storage unit 300 including a ROM and a RAM, an arithmetic unit 400 including a CPU, and the like.

The X-direction control circuit 100 includes a switching circuit 101, a sensor signal detection circuit 102, and a servo motor control circuit 103.
101 normally outputs a signal in the X direction from the manual control means 18 to the servo motor control circuit 103 to control the servo motor 34 for moving the X frame shown in FIG.

After the reading start signal is input from the operation panel 8 to the sensor signal detection circuit 102, when the detection signal in the X direction is input from the optical sensor circuit 90, the sensor signal detection circuit 102 outputs the switching signal S ₁ , The switching circuit 101 is switched to output the detection signal in the X direction from the optical sensor circuit 90 to the servo motor control circuit 103.

Then, when the detection signal in the X direction from the optical sensor circuit 90 becomes 0, the sensor signal detection circuit 102 outputs the read command signal S ₂ to the calculation unit 400.

Similarly, the Y-direction control circuit 200 also includes a switching circuit 201, a sensor signal detection circuit 202, and a servo motor control circuit 203. The switching circuit 201 normally outputs a signal in the Y direction from the manual control means 18 to the servo motor control circuit 203. To control the servo motor 37 for moving the Y frame shown in FIG.

After the reading start signal is input to the sensor signal detection circuit 202 from the operation panel 8 and the detection signal in the Y direction is input from the optical sensor circuit 90, the sensor signal detection circuit 202 outputs the switching signal S ₃ , The switching circuit 201 is switched to output the detection signal in the Y direction from the optical sensor circuit 90 to the servo motor control circuit 203.

Then, when the detection signal in the Y direction from the optical sensor circuit 90 becomes 0, the sensor signal detection circuit 202 outputs the read command signal S ₄ to the calculation unit 400.

Therefore, when teaching one of the many lead wire insertion holes formed in the substrate, the manual control means 18 is used.
The four operating keys 8b are used to specify the moving direction of the substrate P in the X and Y directions, and the substrate is placed at or near the position where the spot light from the light source 65 in FIG. After moving, the reading start key (not shown) is pressed to finely adjust the spot light so as to make the insertion hole H clear. Thereafter, the minute movement of the substrate is automatically controlled by the detection signal from the optical sensor circuit 90. . That is, the servo motors 34 and 37 are driven so that the detection signals from the four photoelectric elements 75a to 75d of the optical sensor 75 shown in FIG.

When the signals from the four light receiving elements 75a to 75d are all equal, the signals in the X and Y directions from the optical sensor circuit 90 are both 0, and at the same time the servo motors 34 and 37 stop, a read command is issued. Signals S ₂ and S ₄ are output.

Encoders 104 and 204 are connected to the servo motors 34 and 37, respectively, for generating a pulse each time a predetermined angle is rotated and detecting the rotation direction thereof. The generated pulses are respectively counted by the counting circuits 105 and 205 according to the rotation direction. The amount of movement of the table 13 (FIG. 4) on which the substrate P is mounted from the coordinate origin in the X and Y directions is measured by counting up or down.

The storage unit 300 includes a mechanical system coordinate storage unit 310 and an insertion data storage unit.

The mechanical system coordinate storage unit 310 stores in advance correction data such as table turning center coordinates, insertion head center coordinates, optical sensor center coordinates, offset amounts between the insertion chuck center and the insertion part center, which are peculiar to the machine.

In the insertion data storage unit 320, a part code indicating a part name or a part symbol of each part to be inserted which is input from the keyboard 8a (used by pulling out) of FIG. An insertion head code for designating an insertion head to be used at the time of inserting a part, data of the insertion direction of the part, and the like are stored, and XY coordinate data of each part insertion position calculated by the calculation unit 400 is stored.

In the parts table storage unit 330, the parts data such as the size and the interval and number of lead wires for each part code of each part to be inserted which is input from the keyboard 8a or from an external data source by means such as punch tape. Etc. are memorized.

The table positioning data storage unit 340 positions the board mounting table so that the rotation angle θ of the board mounting table 13 calculated by the calculation unit 400 and the component insertion position of the board are aligned with the center of the insertion head after the rotation. The XY coordinate data for doing is stored.

The calculation unit 400 includes a coordinate reading calculation unit 410, an insertion head center coordinate calculation unit 420, and a table positioning data calculation unit 430.

The coordinate reading calculation unit 410 counts the count value of the count circuit 105 when the read command signal S ₂ is input from the X direction control circuit 100 and the count value of the count circuit 205 when the read command signal S ₄ is input from the Y direction control circuit 200. The value is read, the difference between the center coordinate of the optical sensor stored in the mechanical system coordinate storage unit 310 and the center coordinate of the insertion head is corrected, and the XY coordinates of the detected insertion hole with respect to the coordinate origin of the printed circuit board are calculated.

The XY coordinates of the substrate read and calculated by the coordinate reading calculation unit 410 are input to the insertion head center coordinate calculation unit 420 and are also stored in the insertion data storage unit 320.

The XY coordinate of this board is the XY coordinate of the lead wire insertion hole closest to the printed board coordinate origin of the insertion part, and this XY coordinate is directly input from the keyboard 8a without using this reading function.
Input coordinates as insert data and insert data storage unit 320
Can be stored in.

The insertion head center coordinate calculation unit 420 inserts the XY coordinates of this board and the part code of the part to be inserted at the coordinate position, the part data corresponding to this part code and the insertion head to be used, the insertion direction data of the part, and the like. The coordinates of the insertion head center are calculated by reading from the storage unit 320 and the parts table storage unit 330.

In particular, in the case of an IC component, the XY coordinate of the board is corrected by calculating the offset amount of the center position of the component and the center coordinate of the insertion head from the insertion direction and the number of pins.

From the insertion head center coordinates calculated in this manner and the insertion direction data of the part stored in the insertion data storage unit 320, the table positioning data calculation unit 430 rotates the printed circuit board rotation angle θ and the The XY coordinates for positioning the insertion head center with respect to the component insertion position of the rotated board are calculated.

At that time, a necessary correction is made based on the table turning center coordinates and the insertion head center coordinates stored in the mechanical system coordinate storage unit 310, and the component data, the insertion head number and the like data stored in the component table storage unit 330. To do.

Then, the data calculated by the table positioning data calculation unit 430 is sequentially stored in the table positioning data storage unit 340 of the storage unit 300.

At the time of actual component insertion, a component is selected according to the component code stored in the insertion data storage unit 320, is supplied to the insertion head selected by the insertion head code, and is stored in the table positioning data storage unit 340. The printed board rotates and moves according to the XY coordinates and the insertion angle θ to insert the component into the printed board.

In this way, for example, as shown in FIG.
The position of the insertion hole of the pin closest to the origin of the board of each component S to be inserted into the board P is sequentially detected by the optical sensor 75, and the component code and insertion direction data are sequentially input from the keyboard 8a. Then, a component insertion program can be created in this electronic component automatic insertion machine.

〔The invention's effect〕
