The relative position to is optimized. Furthermore, when the regulating member 17 is removed from the elongated hole 16, the base plate 9 can freely rotate around the shaft 11, allowing smooth transportation, repair, and maintenance work. . Furthermore, the benefits of compactness during transportation are greater.

Further, two rails 18 are provided on the base plate 9 in the front and back direction, 19 is a moving plate having a guide 18a guided on the rail 18, and 20 is a moving plate mounted on the plate 19. A support block 21 is a slider holding plate supported along the support block 20, and 22 is a slider holding plate 22 supported by the slider holding plate 21, which is rotated by the rotation operation of the knob 23 and which is screwed into a screw shaft 24 and can be raised and lowered. 25 is a slider holding plate fixed in a direction perpendicular (horizontal) to the slider 22;
6 is supported by the slider holding plate 25, and the knob 27
A movable slider screwed onto a screw shaft 28 which is rotated by rotation of the slider 26; 29 is a parallel plate spring with one end symmetrically disposed above, below, left and right of the slider 26; 30 is the other end of the parallel plate spring 29; 31 is a guide pin plate that constitutes a support member that engages and supports a printed circuit board, etc. This guide pin plate 31 has a stepped shape of the support rod 30. One end is placed on the part and fixed with a bolt 32, a protruding piece 33 is connected to the distal end, and a guide pin 34 is protruded upward from the protruding end. is engaged with the guide pin 34 and is supported so as to be placed on the protrusion 33. Further, 35, 36 and 37 are respectively a board holding plate, a holding plate holder and a cylinder holder attached on the guide pin plate 31,
A well-known pen cylinder device is constructed.

Furthermore, a guide block 38 having a through hole is installed in front of the left side of the movable plate 19, and the handle 39 is inserted into the cylindrical portion 40 of the guide block 38 via a spring 41 so as to cover the guide block 38. At this time, the cylindrical part 40
A stopper shaft 42 protruding inwardly is inserted into the through hole. In addition, this handle 39
The pressed position is held by rotating the handle 39 following the pressing operation.

Further, 43 is a stopper plate fixed to the left side of the base plate 9, 44 is a bracket on which the stopper shaft 45 is mounted parallel to the length direction of the stopper plate, and 46 is inserted through the stopper shaft 45 at equal intervals. The stopper 47 is a through hole bored in the protruding piece 48 of the stopper, and the through hole 47 is large enough to allow the tip of the stopper shaft 42 to be inserted therethrough. Nuts 49 and 50 are screwed onto the stopper shaft 45 so as to sandwich the stopper 46 from both sides.

In the structure as described above, first, a printed circuit board P having a large number of identical printed patterns is prepared, and a through hole H is formed at the end of the printed circuit board P (usually, this through hole is formed when printing the printed pattern. ) is inserted into the guide pin 34 and placed on the protrusion 33. This results in
The printed circuit board is supported by a holding plate holder 36 and a guide pin 34, the edges of which are brought into contact with each other. Next, in order to adjust the positional relationship (especially in the radial direction) between the printed circuit board P supported in this way and the press machine, the regulating member 17 is loosened and the base plate 9 is moved around the shaft 11. After the rotation is made and a proper position is determined, the regulating member 17 is tightened to securely hold this position. Next, the left and right nuts 5 are loosened to move the front plate 6 to the left or right to adjust the amount of deviation in the left and right direction with respect to the press machine.

Further, the knob 27 is rotated to move the slider 26 in the left and right direction, so that the printed circuit board sent into the press machine is properly positioned with respect to the press machine, and the slider 26 is horizontally adjusted. Then, the knob 23 is rotated to move the slider 22 in the vertical direction, and the height position of the printed circuit board P is set correctly via the spring plate 29 and the like associated with the slider 22. That is, by rotating the knob 27 and rotating the knob 23, the position of the printed circuit board P with respect to the press machine is accurately set. Next, the stopper 46
are maintained at equal intervals for each of the printed patterns, corresponding to the amount of feed of the printed circuit board P, and the nuts 49 and 50 reliably maintain this interval.

Here, when feeding the printed circuit board P supported as described above to the press machine, first grasp the handle 39 with your hand and press the stopper 46.
Push the handle 39 upward in the front-back direction. In addition,
At this time, the printed circuit board P placed as described above is pushed forward at each interval between the stoppers 46. Then, when the stopper shaft 42 in the handle 39 faces the through hole 47, the handle is pushed downward, and when it is completely pushed in, the handle 39 is rotated. Then, as described above, the tip of the stopper shaft 42 is inserted into the through hole 47 provided in the protrusion 48 of the stopper 46, and this insertion state is maintained by the rotation operation (not shown). ). Here, the printed circuit board P placed in the press machine is cut into a predetermined size at the extruded intervals. That is, the printed circuit board P is fed out at every interval between the stoppers 46 (more specifically, every interval between the through holes 47),
The intended cutting and edging of the printed circuit board P can be carried out accurately and without danger. Note that in order to correctly set the feed amount in this case, the position of the stopper on the screw rod 45 must be selected precisely. Further, since the relative position of the through hole H on the printed circuit board P with respect to the printed pattern has already been determined at the time of printing, using this, the guide pin 34 is placed at a position corresponding to the through hole 47. If the printed circuit board has a slight difference in shape or size, the stopper 46
A large number of printed circuit boards can be cut out correctly without having to adjust the position of the board.

In addition, above, we have talked about cutting out a printed circuit board into multiple printed circuit boards at equal intervals, but this is not limited to cutting out printed circuit boards, and can also be used for all kinds of processing on printed circuit boards, such as drilling holes and attaching parts. Of course, it can be applied to Further, facing the protruding piece 33,
By providing a notch or the like on the press machine side that can sufficiently accommodate this, the unnecessary portion of the printed circuit board can be made smaller, and waste of the printed circuit board during cutting can be prevented.

As described above, the present invention provides a rail on a base having a press machine, arranges a movable plate that slides along the rail, and guides printed circuit boards, etc. to the press machine according to the movement of the movable plate. At the same time, in the device for cutting the printed circuit board, etc. using this press machine, a front plate is attached to the front side of the base so as to be movable in the left-right direction of the base, and the movement position of the front plate in the left-right direction is restricted. A pair of stopper members are attached to the left and right sides of the base, and bolts are screwed into these stopper members with their tips touching the left and right sides of the front plate, and the front plate is adjusted by adjusting the protrusion and retraction of these bolts. The base plate, on which the rail and the movable plate that slides along the rail are arranged, can be freely rotated through a support shaft attached to one side of the front plate, while adjusting the left and right position relative to the base. A regulating member is screwed into a long hole provided on the side opposite to the supporting shaft side of the base plate, the long diameter of which corresponds to the rotating direction of the base plate, and the screwing position of the regulating member with respect to the long hole is adjusted. Since the mounting position of the base plate with respect to the base is regulated, the device for delivering printed circuit boards etc. can be made more compact, and maintenance and inspection can be easily performed. Furthermore, according to the present invention, the front plate is movable with respect to the base and fixed at a predetermined position, so that printed circuit boards and the like can be correctly set in a press machine and the like.
