To this end, we provide a flexible circuit board punching tool to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a flexible circuit board whole board punching tool, including a connecting plate 1, the inner side of the connecting plate 1 is provided with a knife groove 2, when the cutter 12 moves downward to punch the flexible circuit board, the knife groove 2 can reserve space for the cutter 12 in advance, which can prevent the cutter 12 from contacting the connecting plate 1 and causing damage, the upper surface of the connecting plate 1 is fixedly connected with a guide column 3, the top of the guide column 3 is fixedly connected with a support plate 4, the outer surface of the guide column 3 is slidably connected with a slide plate 5, the support plate 4 can make the guide column 3 and the guide column 3 form a whole, increase the stability of the guide column 3, the upper surface of the slide plate 5 is fixedly connected with a support seat 6, the inner wall of the support seat 6 is slidably connected with a guide rod 7, the bottom end of the guide rod 7 is fixedly connected with a support frame 8, the lower surface of the support frame 8 is fixedly connected with a rubber pressing plate 9, and the rubber pressing plate 9 has an inclined angle, the support seat 6 can support the guide rod 7 to slide up and down, the rubber pressing plate 9 is made of rubber, and the rubber is relatively soft. The flexible circuit board will not be damaged when pressure is applied. When the rubber pressure plate 9 with an inclined angle applies pressure downward to the flexible circuit board, the inclined angle can support the flexible circuit board outward, thereby increasing the flatness of the flexible circuit board during punching and cutting, and the outward support can better limit the sliding of the flexible circuit board. The outer sleeve of the guide rod 7 is provided with a spring 10, one end of the spring 10 is fixedly connected to the lower surface of the support seat 6, and the other end of the spring 10 is fixedly connected to the upper surface of the support frame 8. After the slide plate 5 applies downward pressure, the rubber pressure plate 9 contacts the flexible circuit board, and the support frame 8 compresses the spring 10. After the flexible circuit board is punched and cut, the slide plate 5 slides upward, and the spring 10 pushes the support frame 8 to slide downward and reset to prepare for the next punching and cutting. The lower surface of the slide plate 5 is fixedly connected to a tool holder 11, and a cutter 12 is detachably connected to the interior of the tool holder 11. The cutter 12 is installed through the tool holder 11, and can be replaced in a detachable manner after the cutter 12 is damaged or worn.

[0025] The upper surface of the slide plate 5 is fixedly connected with a connecting seat 13, and the inner wall of the connecting seat 13 is slidably connected with two clamping blocks 14, wherein a positioning groove 18 is provided on the inner side of one clamping block 14, and a positioning pin 19 is fixedly connected to the outer surface of the other clamping block 14, and the outer surface of the positioning pin 19 is in sliding contact with the inner wall of the positioning groove 18, and the positioning groove 18 and the positioning pin 19 are connected to each other, so that the two clamping blocks 14 become a whole after tightening, so that the pressure rod on the punch press can be fixed more stably, so that the pressure rod can drive the slide plate 5 to slide up and down more stably, and the inner side of the clamping block 14 is threadedly connected with the screw rod 15, and the outer surface of the screw rod 15 is in contact with the connecting rod 18. The inner wall of the seat 13 is rotatably connected, and the outer surface of the screw rod 15 is fixedly connected with a positioning block 20. The outer surface of the positioning block 20 is rotatably connected to the inner side wall of the connecting seat 13. When the screw rod 15 supports the clamping block 14, the clamping block 14 will generate a reaction force on the screw rod 15. In order to increase the supporting force of the screw rod 15 on the clamping block 14, the supporting force of the screw rod 15 is increased by the positioning block 20, and the stability of the clamping block 14 is maintained. It is connected to the punch pressure rod through the connecting seat 13. After the screw rod 15 rotates, it pushes the clamping block 14 to move, shrinks the distance between the clamping block 14 and the punch pressure rod, and fixes the punch pressure rod to limit the punch pressure rod from detaching from the connecting seat 13.

[0026] A stabilizing mechanism 16 is provided on the outside of the connecting seat 13, which can improve the stability of the screw rod 15 when supporting the clamping block 14, prevent the screw rod 15 from rotating due to equipment vibration, and increase the stability of the punching tool during operation. The stabilizing mechanism 16 includes a sleeve 1601, the outer surface of the sleeve 1601 is fixedly connected to the outer surface of the connecting seat 13, and the inner wall of the sleeve 1601 is slidably connected with a sleeve 1602. The sleeve 1601 can support the sliding of the sleeve 1602 and maintain the stability of the sleeve 1602 when sliding. The outer surface of the sleeve 1602 is fixedly connected with a guide rail 1603, and the outer surface of the guide rail 1603 is slidably connected to the inner side wall of the sleeve 1601. A spring 2 1604 is sleeved on the outside of the screw rod 15, one end of the spring 2 1604 is fixedly connected to the outer surface of the connecting seat 13, and the other end of the spring 2 1604 is fixedly connected to the inner bottom wall of the sleeve 1602 Then, when the sleeve 1602 slides, the guide rail 1603 is blocked by the sleeve 1601 to prevent the sleeve 1602 from rotating, so that the sleeve 1602 only has the function of sliding back and forth. After the sleeve 1602 is pushed, it slides toward the inside of the sleeve 1601, and at the same time, the sleeve 1602 compresses the spring 2 1604 to shrink. After the sleeve 1602 loses the external thrust, the spring 2 1604 pushes the sleeve 1602 to slide outside the sleeve 1601. One end of the sleeve 1602 is fixedly connected with the chuck 1 1605, and the outer surface of the screw rod 15 is fixedly connected with the chuck 2 1606. The outer surface of the chuck 2 1606 contacts the outer surface of the chuck 1 1605. The teeth on the chuck 1 1605 and the chuck 2 1606 have an inclined angle, which is convenient for the chuck 1 1605 to slide backward after the chuck 2 1606 rotates, and the chuck 2 1606 can be driven to rotate while the screw rod 15 rotates.

[0027] A slide rail 17 is fixedly connected to the upper surface of the connecting plate 1, and the top of the slide rail 17 is fixedly connected to the lower surface of the support plate 4. The inner wall of the slide rail 17 is slidably connected to the outer surface of the support frame 8. When the slide plate 5 slides downward to drive the rubber pressure plate 9 to apply pressure to the flexible circuit board, the guide rod 7 will bear a lot of pressure. In order to prevent the guide rod 7 from being damaged by excessive force, the slide rail 17 is used to maintain the stability of the support frame 8 when sliding, reduce the force on the guide rod 7, and increase the stability of the support frame 8 when sliding up and down.

[0028] Working principle: first, put the punch press rod into the connecting seat 13, and then rotate the screw rod 15 to contract the clamping block 14 to fix the punch press rod. While rotating the screw rod 15, chuck 2 1606 also rotates, and chuck 1 1606 pushes chuck 1 1605 to move backward. Chuck 1 1605 pushes the sleeve 1602 to move backward and compresses spring 2 1604. After the screw rod 15 completes the contraction of the clamping block 14, stop rotating the screw rod 15, and spring 2 1604 pushes the sleeve 1602 to move outside the sleeve 1601, and at the same time drives chuck 1 1605 to move outward. Chuck 1 1605 is in tight contact with chuck 2 1606, so that the screw rod 15 will not rotate without external force.

[0029] After the punch press rod is connected, the punch press rod pushes the slide plate 5 to slide downward and drives the cutter 12 to punch and cut the flexible circuit board. The rubber pressure plate 9 is installed slightly lower than the cutter 12. First, the rubber pressure plate 9 contacts the flexible circuit board to press and fix the flexible circuit board, and supports and presses the flexible circuit board outward at an inclined angle. While the rubber pressure plate 9 contacts the flexible circuit board, the rubber pressure plate 9 pushes the support frame 8 to move upward, and the support frame 8 pushes the guide rod 7 to slide upward and compresses the spring 10. Then the cutter 12 punches and cuts the flexible circuit board, and the punch press rod drives the slide plate 5 to slide upward. The spring 10 pushes the support frame 8 and the guide rod 7 to slide downward to prepare for the next punching.
