【Example】

 A printed circuit board divider according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the entire printed circuit board dividing machine according to an embodiment of the present invention. As shown in the figure, the dividing mechanism unit 1 is arranged on the pedestal 2, and the control unit for controlling the dividing mechanism unit 1 is arranged inside the pedestal 2.

2 and 3 show details of the dividing mechanism section. As shown in the figure, belts 4 and 4 are wound around guides 3 and 3 on both sides, and these belts are driven by a motor 5. That is, a belt conveyor that conveys the printed circuit board material to the right is formed.

Reference numerals 6 and 7 are stoppers driven by an air cylinder, which move in and out of the moving path of the printed board material. Reference numerals 8, 8 and 9, 9 denote two sets of positioning clampers having downwardly-arranged tapered positioning pins, which are vertically driven by an air cylinder.

Reference numerals 10, 11 and 12 are light reflection type sensors for detecting the presence or absence of the printed circuit board material at each position. Rollers 13, 13 are arranged above the right ends of the belts 4, 4.

The upper die mounting base 14 is supported so as to be vertically movable, and is vertically driven by an upper die air cylinder 15. An upper die 16 is replaceably attached to the upper die mounting base 14. The lower die mounting base 17 is supported so as to be vertically movable, and is vertically driven by the lower die air cylinder 18. A lower die 19 is replaceably attached to the lower die mounting base 17.

As shown in FIG. 4, air cylinders 22, 22 are attached to the upper die mounting base 14. Further, as shown in FIG. 5, when a part of the upper die blade comes into contact with the printed circuit board material, the other part of the blade is separated from the printed circuit board material by the distances A and B so that the height of the blade is different. Is provided. The maximum difference in blade height is the thickness of the printed circuit board material.

A chute 20 is provided below the upper mold 16 and the lower mold 19, and a cushioning material 21 is attached to the chute 20. The output signals of the sensors 10, 11 and 12 are input to the control unit, and the control unit controls the movement of each air cylinder and the motor 5.

Next, the operation of the printed board dividing machine will be described. First, the printed circuit board material is placed on the left side of the belts 4 and 4 shown in FIGS. Then, the sensor 10 detects the printed circuit board material, the motor 5 rotates, and the printed circuit board material is sent to the right.

Further, the stopper 6 rises to stop the printed circuit board material, and when the printed circuit board material is detected by the sensor 11, the motor 5 stops and the positioning clamps 8, 8 descend. The tapered positioning pins of the positioning clampers 8 and 8 enter the holes of the printed board material, and the positioning clampers 8 and 8 position the printed board material.

Next, the lower die 19 moves up to a position in contact with the printed circuit board material, and the upper die 16 moves down. Before the upper mold 16 contacts the printed board material, the air cylinders 22 and 22 press the printed board material.

The upper mold 16 is further lowered, and the printed circuit board is pushed out from the printed circuit board material. At this time, the shearing points of the upper die 16 are dispersed and the load applied to the upper die mounting base 14 and the lower die mounting base 17 is small. The printed circuit board that has been punched out falls, slides down the shoe 20, and is taken out forward. A shock absorbing material 21 is attached to the chute 20 so that the printed circuit board is not damaged by the impact.

After that, the upper mold 16 returns to the upper position, the lower mold 19 returns to the lower position, and the positioning clampers 8, 8 further return to the upper position. Further, the stopper 6 descends and the belt conveyor feeds the printed circuit board material to the right.

Next, the printed circuit board material is stopped by the stopper 7, and the printed circuit board is pushed out from another position of the printed circuit board material by the action of the sensor 12, the positioning clamps 9, 9 and the lower mold 19 and the upper mold 16. .

When the second printed circuit board is punched out, the upper die 16 returns to the upper position, the lower die 19 returns to the lower position, and the positioning clamps 9, 9 further return to the upper position. Further, the stopper 7 descends, and the printed board material is sent to the right by the belt conveyor and discharged. The printed circuit board material drops while being inclined from the belt conveyor, but is pressed by the rollers 13 and 13 and does not come into contact with the positioning clamper 9.

The time between the division of the first printed circuit board and the division of the second printed circuit board is variable by the timer of the control unit, and is set according to the work cycle.

Although the embodiment is configured as described above, the invention is not limited to this. For example, instead of manually placing the substrate material on the belt conveyor, the substrate material may be supplied to the belt conveyor by the substrate supply device.
