[Conventional technology]

FIG. 3 shows the configuration of a conventional printed circuit board regulating device. In Figure 3, 1a ・1b is a first regulation pin and a second regulation pin, which are connected to cylinders 2a and 2b, respectively. is attached to. The first regulating pin 1a and the second regulating pin 1b have tips It is a stepped pin with a conical shape and a flange in the middle. 3 is a moving block that holds the cylinder 2a, and can be moved horizontally to the plate 4. Supported. The plate 4 has a long hole 6 through which a fixing bolt 5 passes. and is fixed to the device housing 7. 8 is a fixed block that holds cylinder 2b. It is fixed to the device housing 7. 9 is a holding plate, which is fixed to the device housing 7. It is. A belt 10 conveys the printed circuit board 11. Printed circuit board 1 1 has a positioning hole 2 through which the first regulation pin 1a and the second regulation pin 1b pass. It is set up in several places.

0003 Next, the operating method of the above conventional example will be explained. In Figure 3, the second regulating pin 1b as a reference, the position corresponding to the pitch dimension of the positioning holes of the printed circuit board 11. The first regulating pin 1a is set at the position. To do this, first manually move the Move the moving block 3 in the direction. Next, attach the bolt 5 to the nut located on the back of the plate 4. The movable block 3 is fixed by screwing it into a socket (not shown).

0004 In this way, with the conventional printed circuit board regulating device described above, it is difficult to move the printed circuit board manually by the operator. By moving and fixing block 3, presets with different positioning hole pitch dimensions can be created. It is possible to change the model of the main board.

[0005]

[Problem that the idea aims to solve]

However, with the conventional printed circuit board regulating device described above, the Because the moving block 3 is moved and fixed, the pitch dimension of the positioning holes is There was a problem in that it was not possible to automatically switch between different printed circuit board models.

[0006] This invention solves these conventional problems, and it is possible to We aim to provide an excellent printed circuit board regulating device that can be automatically replaced by a motor. This is the purpose.

[0007]

[Means to solve the problem]

In order to achieve the above object, the present invention has developed a printed base having positioning holes in two places. a means for conveying the plate; a first regulating pin and a second regulating pin passing through the positioning hole; driving the control pin, the first control pin, and the second control pin up and down, respectively; The cylinder and the cylinder that drives the first regulation pin can be held and moved horizontally. The movable block is supported by the movable block, and the movable block is fitted with the threaded part, and one end is driven. A drive signal is sent to the ball screw attached to the drive motor output shaft and the drive motor. and a second standard corresponding to the pitch dimension of the positioning holes of the printed circuit board. The first regulating pin can be automatically moved and fixed in place using the regulating pin as a reference. This is how it was done.

[0008]

[Effect]

Therefore, according to the present invention, by driving the motor with a drive signal, the board can be The screw turns a predetermined number of times, which causes the moving block to move horizontally by a predetermined distance. movement, the first regulating pin can be easily moved to the specified position, and the first regulating pin can be easily moved to the specified position. The distance between the second regulating pin and the second regulating pin can be easily and accurately set to a predetermined dimension. I can do that. Therefore, the belt transports the printed circuit board to the regulation position and stops it. Then, since the cylinder operates, the first pin and second regulating pin rise, and the cylinder is activated. Penetrate each of the two positioning holes provided on the printed circuit board, and attach the printed circuit board to the bell. It can be regulated at a predetermined position by raising it slightly above the original position.

【Example】

Figure 1. FIG. 2 shows the configuration of an embodiment of the present invention. In FIG. 1, 21a ・21b is a first regulating pin and a second regulating pin, which are respectively connected to the cylinder 22a. It is attached to the output shaft of 22b. First regulation pin 21a and second regulation The pin 21b is a stepped pin with a conical tip as shown in FIG. There is. A moving block 23 holds the cylinder 22a. 24 is Guy The movable block 23 is horizontally movably supported and attached to the device casing 25. It is attached. 26 is a ball screw, and a moving block 23 is fitted into the screw portion. One end is supported by the device housing 25, and the other end is connected to the output shaft of the drive motor 27. It is attached. The motor 27 is attached to the device housing 25. 28 is a transmitting device that sends a signal to the motor, and the pitch of the positioning holes 33a and 33b, which will be described later, is The number of emitted pulses is registered in advance for each printed circuit board model according to the chip dimensions. . 29 is a fixing block, and 30 is a holding plate, both of which are attached to the device housing 25. It is being 31 is a belt, which is driven by a pulley supported by the device housing. The printed circuit board 32 is transported by The printed circuit board 32 is positioned as shown in FIG. Holes 33a and 33b for fitting are provided.

0010 Next, the operation of the above embodiment will be explained. In the above embodiment, the transmitting device 28 The number of output pulses corresponding to the pitch dimension of the positioning holes provided on the printed circuit board is predetermined.

It rotates a predetermined number of times depending on the location. As a result, the moving block 23 moves in the direction of arrow A. The first regulating pin 21a is guided by the guide rail 24 and moved a predetermined distance. It is set at a predetermined position corresponding to the hole 33a. At this time, the motor 27 is in the hold state. Since the movable block 23 is in a state of It is held in place without any problems. In this state, the printed circuit board 32 is held by the belt 31. When it is transported in the direction of arrow B, it is stopped at the regulation position by a stopper (not shown). Ru. Then, a sensor (not shown) detects the printed circuit board 32 and uses the signal to detect the printed circuit board 32. Since the cylinders 22a and 22b operate, the first regulating pin 21a and the second regulating pin 21a The control pin 22b rises and penetrates into the holes 33a and 33b, respectively. This will cause the printer to The top board 32 is fixed by the stepped portions of the first regulating pin 21a and the second regulating pin 21b. It rises, moves away from the belt 31, is energized by the presser plate 30, and is regulated in a predetermined position. Ru.

[0011] In this way, according to the above embodiment, the motor 27 is driven by the transmitting device 28. , it is possible to automatically set the first regulating pin 21a to a predetermined position corresponding to the hole 33a. It has the advantage of Although not shown in the above embodiment, the printed circuit board 32 A means for determining the model of the printed circuit board 32 is provided before the printed circuit board 32 is transported to the regulation position, By this means, the transmitter 28 is controlled and the positioning hole pitch of the printed circuit board 32 is determined. If configured to output a number of pulses according to the dimensions, the first regulating pin 21a The positioning hole pitch can be changed automatically to match the above pitch dimension. It has the effect of easily realizing mixed production of multiple types of printed circuit boards with different dimensions. do.
