Description

Technical Field

[0001] This utility model belongs to the field of PCB board processing technology, specifically relating to a punching device that can improve the processing accuracy of PCB boards. Background Technology

[0002] PCB, also known as printed circuit board, is a carrier of various electronic components that are soldered onto its surface.

[0003] In the current technology center, when producing circuit boards, multiple fixing holes need to be drilled on the circuit board to fix the circuit board on the fixing platform. Then, a drill bit with the appropriate hole diameter is used to drill holes on the surface of the circuit board to facilitate the subsequent installation and fixing of the circuit board.

[0004] When drilling circuit boards, drilling equipment can only process circuit boards of a single size. When processing circuit boards of other sizes, different fixed molds need to be changed. Repeated disassembly and reassembly of the fixed molds can cause the molds to shift when fixed, which in turn causes the drilling position on the circuit board to shift, affecting the punching accuracy. Furthermore, when punching CB boards, the PCB is affected by the impact force and the four sides will warp, causing the punching position on the PCB board to deform, further affecting the punching accuracy. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a stamping device that can improve the processing accuracy of PCB boards.

[0006] The technical solution adopted to solve the above technical problems is: a punching device that can improve the processing accuracy of PCB board, including a fixed table, a through hole two is opened at the top of the fixed table, a support frame is fixedly connected to the upper inner side wall of the through hole two, a mold is placed on the upper surface of the support frame, and a clamping and fixing component for clamping and fixing the mold is provided in the through hole two.

[0007] The clamping and fixing assembly includes bidirectional threaded rods arranged in an alternating cross configuration. Both ends of the bidirectional threaded rods are rotatably connected to the inner sidewall of the second through hole. A knob is fixedly connected to one end of each bidirectional threaded rod. A limiting shell surrounds the upper part of each bidirectional threaded rod. Both ends of the limiting shell are fixedly connected to the inner sidewall of the second through hole. A symmetrically arranged displacement plate is threaded through the sidewall of each bidirectional threaded rod. The sidewall of the displacement plate has a sliding hole that slides with the limiting shell. A clamping plate is fixedly connected to the top of each displacement plate. A pressing and limiting assembly for pressing and limiting the PCB board is provided at the top of the clamping plate.

[0008] With the above technical solution, when assembling the mold, the mold is placed on the support frame. The rotation of the two bidirectional threaded rods is driven by the knobs on both sides. With the limiting shell, the displacement plates and clamping plates on both sides move in opposite directions. The four-way clamping plates clamp the mold in the center, ensuring that the mold is firmly fixed, improving the processing accuracy, and is suitable for assembling molds of different sizes. It is highly practical.

[0009] Furthermore, the clamping plate and the adjacent displacement plate are all fixedly connected to a heightening plate, and the lower surface of the clamping plate is on the same plane as the upper surface of the support frame.

[0010] The above technical solutions ensure that the mold is placed stably and clamped, avoiding shaking or tilting caused by height differences and improving the verticality of punching.

[0011] Furthermore, a protective pad is adhered to the clamping surface of the clamping plate.

[0012] The above technical solution is used to clamp and protect the mold, thus preventing damage to the mold.

[0013] Furthermore, the pressing and limiting assembly includes a housing fixed to the top of the clamping plate. Each housing has a screw rod rotatably connected through it. Each screw rod has a knob fixed to its top. Each screw rod has a lifting plate threaded through its side wall. Each lifting plate has an installation groove on its inwardly converging side wall. Each installation groove has a pressing plate installed in it via a quick-release mechanism. When the four pressing plates are assembled, their shape matches the mold.

[0014] With the above technical solution, when punching a PCB board, the PCB board is placed on a mold of the corresponding size. As the mold is clamped and fixed, the pressing plates in all directions are driven to gather inward. The pressing plates automatically assemble into a shape that matches the PCB board and the mold. When pressing and limiting the PCB board, the screw is driven to rotate by the second knob. In conjunction with the housing limit, the lifting plate and pressing plate are driven to descend until the edge of the PCB board is covered and pressed. The pressing is stable, ensuring that the PCB board does not shift during the punching process. This avoids the impact force during punching causing the PCB edge to warp and the punching position to deform, thus improving the punching accuracy.

[0015] Furthermore, the quick-release mechanism includes a fixing ring fixedly connected to the side wall of the lifting plate. Each side wall of the fixing ring is fixedly connected to a spring, and the other end of each spring is fixedly connected to a bolt. The end of the bolt penetrates the inner wall of the mounting groove.

[0016] The above technical solution supports quick assembly and disassembly of the pressing plate, making it easy to replace the pressing plate with one that matches the mold, resulting in high assembly and disassembly efficiency.

[0017] Furthermore, a protective pad is adhered to the lower surface of the pressing plate, a protrusion is provided on the top of the pressing plate, and a locking hole corresponding to the position of the plug is opened on the side wall of the protrusion.

[0018] Through the above technical solution, the protective pad buffers the pressure and prevents the PCB board from being dented or deformed. When replacing the press plate, pull the plug outward to disengage it from the locking hole to release the lock on the press plate. Insert the protrusion on the replacement press plate into the mounting slot, release the plug spring, push the plug back to the locking hole, and the assembly is completed. The assembly and disassembly are convenient.

[0019] Furthermore, the side wall of the fixed platform is provided with a through hole, and a waste collection drawer is slidably connected to the inner side wall of the through hole.

[0020] With the above technical solution, the debris generated during punching falls into the waste collection drawer through the through hole, which removes the punching waste in time and avoids the accumulation of waste debris from affecting the processing accuracy or equipment operation.

[0021] The beneficial effects of this utility model are as follows: (1) By setting the clamping and fixing component and the pressing and limiting component, the clamping and fixing component clamps the mold in the center, ensuring that the mold is firmly fixed, improving the processing accuracy, and is suitable for assembly and use of molds of different sizes. The pressing and limiting component, together with the clamping and fixing component, presses the edge of the PCB board in a covering manner, and the pressing is stable, ensuring that the PCB board does not shift during the punching process, thus improving the punching accuracy; (2) By setting the pressing plate and the quick-release mechanism, the pressing plate can be quickly disassembled and assembled, making it easy to replace the pressing plate that is compatible with the mold, and the disassembly and assembly efficiency is high.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] like Figures 1-6 As shown, the punching device of this embodiment, which can improve the processing accuracy of PCB board, includes a fixed table 1. The top of the fixed table 1 has a through hole 2 102. The upper inner side wall of the through hole 2 102 is fixedly connected to a support frame 6. A mold 2 is placed on the upper surface of the support frame 6. A clamping and fixing component 3 for clamping and fixing the mold 2 is provided in the through hole 2 102. The side wall of the fixed table 1 has a through hole 101. A waste collection tray 7 is slidably connected to the inner side wall of the through hole 101. The debris generated during punching falls into the waste collection tray 7 through the through hole 101, so as to remove the punching waste in time and avoid the accumulation of waste debris from affecting the processing accuracy or equipment operation.

[0031] The clamping and fixing assembly 3 includes bidirectional threaded rods 302 arranged in an alternating upper and lower cross configuration. Both ends of the bidirectional threaded rods 302 are rotatably connected through the inner wall of the second through hole 102. A knob 303 is fixedly connected to one end of each bidirectional threaded rod 302. A limiting shell 301 surrounds the upper part of each bidirectional threaded rod 302. Both ends of the limiting shell 301 are fixedly connected to the inner wall of the second through hole 102. Symmetrically arranged displacement plates 304 are threadedly connected to the side walls of each bidirectional threaded rod 302. Sliding holes 3041 are opened on the side walls of the displacement plates 304, which slide in conjunction with the limiting shells 301. A clamping plate 305 is fixedly connected to the top of each displacement plate 304. An increasing plate 306 is fixedly connected between the lower clamping plate 305 and the adjacent displacement plate 304. The lower surface of the clamping plate 305 is flush with the support frame 6. The upper surfaces are on the same plane to ensure that the mold 2 is placed stably and clamped, avoiding shaking or tilting due to height difference, and improving the verticality of punching. The clamping surfaces of the clamping plate 305 are all bonded with protective pads 307 to clamp and protect the mold 2 and prevent damage to the mold 2. The top of the clamping plate 305 is provided with a pressing and limiting component 4 for pressing and limiting the PCB board. When assembling the mold 2, the mold 2 is placed on the support frame 6, and the two bidirectional threaded rods 302 are driven to rotate by the knobs 303 on both sides. With the limiting shell 301, the displacement plates 304 and clamping plates 305 on both sides move towards each other in sync. The four-way clamping plate 305 clamps the mold 2 in the center to ensure that the mold 2 is fixed firmly, improves processing accuracy, and is suitable for assembling and using molds 2 of different sizes. It is highly practical.

[0032] The pressing and limiting assembly 4 includes a housing 401 fixed to the top of the clamping plate 305. Each housing 401 has a screw 402 rotatably connected to its top. Each screw 402 has a knob 403 fixed to its top. Each screw 402 has a lifting plate 404 threadedly connected to its sidewall. Each lifting plate 404 has an inwardly converging sidewall with a mounting groove 4041. Each mounting groove 4041 contains a pressing plate 405 installed via a quick-release mechanism 5. When the four pressing plates 405 are assembled, their shape matches the mold 2. When punching holes in the PCB board, the PCB board is placed on the mold 2 with the corresponding dimensions. While clamping and fixing the mold 2, the pressing plates 405 in all directions are driven to gather inward. Each pressing plate 405 automatically assembles into a shape that matches the PCB board and the mold 2. When pressing and limiting the PCB board, the screw 402 is driven to rotate by the knob 403. In conjunction with the housing 401, the lifting plate 404 and the pressing plate 405 are lowered until the edge of the PCB board is covered and pressed. The pressing is stable, ensuring that the PCB board does not shift during the punching process. This avoids the impact force during punching causing the PCB edge to warp and the punching position of the PCB board to deform, thus improving the punching accuracy.

[0033] The quick-release mechanism 5 includes a fixing ring 501 fixedly connected to the side wall of the lifting plate 404. The side wall of the fixing ring 501 is fixedly connected to a spring 502. The other end of the spring 502 is fixedly connected to a plug 503. The end of the plug 503 penetrates the inner wall of the mounting groove 4041, supporting the quick disassembly and assembly of the pressing plate 405. This facilitates the replacement of the pressing plate 405 that is compatible with the mold 2, resulting in high disassembly and assembly efficiency.

[0034] The lower surface of the pressing plate 405 is covered with a second protective pad 4051. The top of the pressing plate 405 is provided with a protrusion 4052. The side wall of the protrusion 4052 is provided with a locking hole 4053 corresponding to the position of the plug 503. The second protective pad 4051 buffers the pressure and prevents the PCB board from being dented or deformed. When replacing the pressing plate 405, pull the plug 503 outward to disengage it from the locking hole 4053 to release the lock on the pressing plate 405. Insert the protrusion 4052 on the replacement pressing plate 405 into the mounting groove 4041, release the spring 502 of the plug 503 to push the plug 503 back into the locking hole 4053 to complete the assembly. The assembly and disassembly are convenient.

[0035] The working principle of this embodiment is as follows: During use, when assembling the mold 2, the mold 2 is placed on the support frame 6. The two bidirectional threaded rods 302 are driven to rotate by the knobs 303 on both sides. With the limiting shell 301, the displacement plates 304 and clamping plates 305 on both sides move towards each other. The four-way clamping plates 305 clamp the mold 2 in the center, ensuring that the mold 2 is firmly fixed. When punching the PCB board, the PCB board is placed on the mold 2 of the corresponding size. Because the mold 2 is clamped and fixed at the same time, the pressing plates 405 in all directions are driven to gather inward. Each pressing plate 405 automatically assembles into a shape that matches the PCB board and mold 2. When pressing and limiting the PCB board, the screw 402 is driven to rotate by the knob 403. In conjunction with the housing 401 limiting, the lifting plate 404 and pressing plate 405 are lowered until the edge of the PCB board is covered and pressed. The pressing is stable, ensuring that the PCB board does not shift during the punching process. After that, the punching process can be carried out. The debris generated during punching falls into the waste collection tray 7 through the through hole 101, which removes the punching waste in time and avoids the accumulation of waste debris from affecting the processing accuracy or the operation of the equipment.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
