Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board manufacturing technology, specifically to a punching equipment for flexible circuit board manufacturing. Background Technology

[0002] Flexible printed circuit boards (FPCs) are widely used in consumer electronics such as mobile phones, TWS earphones, automotive electronics, and medical devices due to their flexibility, thinness, and high integration. In the production of FPCs, punching equipment is one of the key processing tools, mainly used for precision punching of the FPC substrate, cover film, and reinforcing plate to create shapes, holes, and openings. After punching, the flexible printed circuit board also needs to be trimmed and shaped.

[0003] Currently, most flexible circuit board (Flexible Printed Circuit) processing involves drilling holes in the Flexible Circuit Board (FPCB), followed by transferring it to a cutting machine for trimming. This process is cumbersome and time-consuming, requiring multiple machines and increasing processing costs. Furthermore, it cannot simultaneously drill and trim the FlexPCB, and the punching structures are mostly fixed, only suitable for one type of FlexPCB. This lack of flexibility prevents quick template changes for different sizes and specifications. Utility Model Content

The following will refer to the accompanying drawings. Figures 1-7 The present invention will be described in detail with reference to the embodiments.

[0025] A punching device for producing flexible circuit boards includes an operating table 1. A through slot 2 and several grooves 3 are fixedly provided on the operating table 1. The through slot 2 is located at the center of the operating table 1, and a waste bin 18 is movably placed below the through slot 2. The flexible circuit board waste generated during punching can fall from the through slot 2 into the waste bin 18 below. There are four grooves 3, which are symmetrically arranged on the four sides of the through slot 2 and are adapted to the clamping parts 6. A support frame 4 is fixedly provided on the through slot 2, and the support frame 4 can be used to support and fix the support table 5.

[0026] The top wall of the support frame 4 is detachably equipped with a support platform 5. The top wall of the support frame 4 is fixedly equipped with four positioning grooves 19. The bottom wall of the support platform 5 is fixedly equipped with four positioning columns 20 at corresponding positions. The bottom walls of the four positioning grooves 19 and the bottom walls of the four positioning columns 20 are respectively fixedly equipped with magnet blocks 21 that attract and match each other. The outer walls of the four corners of the support platform 5 are respectively fixedly equipped with handle rings 22.

[0027] Lifting the handle 22 allows the support platform 5 to be easily lifted upwards, separating the magnets 21 on the bottom walls of the four positioning posts 20 from the magnets 21 on the bottom walls of the four positioning slots 19. A support platform 5 of a different specification can then be replaced. The new support platform 5 is installed on the top wall of the support frame 4, so that the bottom walls of the four positioning slots 19 and the four positioning posts 20 correspond one-to-one and are attracted to each other. At the same time, the clamping parts 6 are used to further reinforce and stabilize the support platform 5.

[0028] A clamping member 6 is movably arranged through the through slot 2 and several grooves 3. The clamping member 6 can fix the support platform 5. Threaded holes 23 are fixedly arranged through the through slot 2 and four grooves 3. The clamping member 6 includes a clamping circular plate 24 arranged in the through slot 2. A T-shaped rod 25 is fixedly arranged on the outer wall of the clamping circular plate 24. The outer wall of the T-shaped rod 25 is threadedly connected to the inner wall of the threaded hole 23.

[0029] Twist the end of the T-shaped rod 25 located at one end of the groove 3, so that it rotates along the threaded hole 23 and approaches the outer wall of the support platform 5, until the side wall of the clamping round plate 24 contacts and abuts against the side wall of the support platform 5, thereby clamping and fixing the support platform 5.

[0030] A mounting frame 7 is fixedly installed on the top wall of the operating table 1. A telescopic rod 8 is fixedly installed at the top of the mounting frame 7. The mounting frame 7 has an inverted U-shaped structure. The telescopic rod 8 is a hydraulic telescopic rod. A hydraulic cylinder is installed on the top wall of the mounting frame 7. The telescopic rod 8 is fixedly installed on the output end of the hydraulic cylinder. The telescopic rod 8 can extend and retract up and down, thereby driving the punching plate 12 to move downward and close to the flexible circuit board for punching and cutting.

[0031] A connecting plate 9 is fixedly installed at the telescopic end of the telescopic rod 8. Limiting grooves 26 are fixedly installed on the two inner side walls of the mounting bracket 7. Both ends of the connecting plate 9 can move up and down within the limiting grooves 26. The limiting grooves 26 can enhance the stability and guidance of the connecting plate 9 moving up and down. When the connecting plate 9 moves to the bottom of the limiting groove 26, the elastic element 30 is compressed to its shortest length, and the upper cutting blade 14 and the lower cutting blade 15 can just contact and abut against each other, so as to smoothly cut the flexible circuit board.

[0032] The bottom wall of the connecting plate 9 is fixedly provided with an adjustment groove 10, and an adjustment plate 11 is movably provided inside the adjustment groove 10. The adjustment groove 10 is horizontally arranged and there are four grooves. Each adjustment groove 10 is movably provided with an adjustment plate 11. The position of the adjustment plate 11 in the adjustment groove 10 can be flexibly moved according to the size and specifications of the punching plate 12 to enhance flexibility.

[0033] The adjusting plate 11 has an L-shaped structure. The blanking plate 12 includes four sets of vertical plates fixedly installed on the outer walls of both sides. The adjusting plate 11 and the blanking plate 12 are detachably connected. The bottom end of the adjusting plate 11 and both ends of the blanking plate 12 are provided with mounting holes 27. Bolt locking parts 28 are detachably installed through the mounting holes 27. The bolt locking parts 28 include threaded rods and nuts. The threaded rods pass through the corresponding mounting holes 27 and are fixed at the other end by nuts, so that the blanking plate 12 can be fixedly installed on the adjusting plate 11.

[0034] A compaction member 13 is fixedly provided on the outer ring of the bottom wall of the punching plate 12, which can compact and fix the flexible circuit board. There are four sets of compaction members 13, which are fixedly provided on the four corners of the bottom wall of the punching plate 12. Each set of compaction members 13 includes a sliding column 29 fixedly provided on the bottom wall of the punching plate 12. An elastic member 30 is fixedly provided on the bottom wall of the sliding column 29. The bottom end of the elastic member 30 is fixedly provided on the bottom wall of the inner groove of the pressure block 31. The bottom end of the sliding column 29 is slidably connected to the side wall of the inner groove of the pressure block 31.

[0035] The compacting component 13 can compact and fix the four corners of the flexible circuit board below. When the telescopic rod 8 moves downward, it drives the compacting component 13 to first contact and compact the flexible circuit board. When the compacting component 13 is not in contact with the flexible circuit board, the elastic component 30 is in the normal state. The inner groove sidewall of the pressure block 31 is fixedly provided with a vertical sliding groove. The bottom end of the sliding column 29 is slidably disposed in the sliding groove. When the compacting component 13 is not in contact with the flexible circuit board, the bottom end of the sliding column 29 is located at the top of the sliding groove.

[0036] When the pressure block 31 moves downward and contacts the flexible circuit board, the bottom end of the sliding column 29 moves downward along the groove. At this time, the elastic element 30 begins to slowly compress, exerting downward pressure on the flexible circuit board, which can fix and press the flexible circuit board to prevent it from moving.

[0037] The bottom wall of the punching plate 12 and the top wall of the support platform 5 are respectively provided with an upper cutting blade 14 and a lower cutting blade 15, a punching blade 16 and a hole 17. The positions of the upper cutting blade 14 and the lower cutting blade 15 are one-to-one, and the positions of the punching blade 16 and the hole 17 are also one-to-one. The hole 17 is set through the support platform 5.

[0038] During the compression of the elastic element 30, since the lowest end of the punching knife 16 is higher than the lowest end of the pressure block 31, and the lowest end of the upper cutting knife 14 is higher than the lowest end of the punching knife 16, the punching knife 16 first contacts the flexible circuit board, and the punching knife 16 passes through the flexible circuit board and extends into the hole 17. The debris generated by punching falls into the waste bin 18 below along the hole 17. The elastic element 30 continues to be compressed, and then the upper cutting knife 14 moves down to contact the flexible circuit board and trims its edges. When the elastic element 30 is compressed to its limit, the bottom end of the sliding column 29 slides to the bottom end of the groove, and the upper cutting knife 14 and the lower cutting knife 15 just come into contact and abut against each other, successfully completing the cutting of the flexible circuit board.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
