Abstract
Description
Technical Field
[0001] This utility model relates to the field of FPC circuit board processing technology, and in particular to an FPC circuit board drilling device. Background Technology
[0002] Circuit boards are an indispensable basic component in electronic devices. They provide the carrier for electrical connections between components and play a vital role in electronic devices because they offer higher electrical performance and smaller size.
[0003] During the production and processing of circuit boards, drilling machines are used to drill holes in them, and clamps are used to hold the circuit boards from both sides. Currently, after the circuit boards are clamped, the drilled areas are left suspended in the air, and the pressure applied by the drilling machine head makes the drilled areas of the circuit boards very prone to cracking. The processing of circuit boards generates debris and dust, and since there is no protective gear for operators on the processing table, operators next to the processing table may inhale the dust, compromising their safety. Utility Model Content
[0004] The purpose of this invention is to solve the problem of circuit board breakage during processing in the prior art, and to propose an FPC circuit board drilling device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An FPC circuit board drilling device includes a base and a drilling head for drilling holes in the FPC circuit board. A bracket and a guide rod are fixedly installed on the base. A telescopic rod II and a fixed platform for supporting the lower end of the circuit board are fixedly installed on the bracket. A rack is slidably sleeved on the guide rod. A movable platform for applying pressure to the upper end of the circuit board is fixedly installed on the rack. A frame is fixedly connected to the output end of the telescopic rod II. A column corresponding to the circuit board is placed inside the frame. A sealing plate that fits against the circuit board and a cutout frame are fixedly installed on the column. A sealing structure for intercepting the circuit board is installed on the base.
[0007] Preferably, the bracket and guide rod are both vertically arranged, the fixed platform and the movable platform are concave structures, a motor is fixedly installed on the bracket, and the output end of the motor is fixedly connected to a rotating shaft connected to a rack and pinion drive. A telescopic rod is fixedly installed on the fixed platform and the movable platform, and a pressure plate that moves against the end of the circuit board is fixedly connected to the output end of the telescopic rod. The fixed platform, the movable platform, and the pressure plate are provided with soft pads that move against the circuit board.
[0008] Preferably, the rotating shaft is horizontally positioned, and a gear that meshes with the rack is fixedly mounted on the rotating shaft, and the pressure plate is horizontally positioned on one side of the circuit board.
[0009] Preferably, the frame is vertically arranged on one side of the support, and a groove is provided on the frame for storing the column.

[0010] Preferably, the sealing structure includes two rotating rods fixedly installed on the base, and a support plate is rotatably installed on the rotating rods.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figures 1-3 An FPC circuit board punching device includes a base 1 and a punching head 2 for punching holes in the FPC circuit board.
[0021] A bracket 3 and a guide rod 4 are fixedly installed on the base 1. A telescopic rod 14 and a fixed platform 5 for supporting the lower end of the circuit board are fixedly installed on the bracket 3. A rack 6 is slidably sleeved on the guide rod 4. A movable platform 10 for applying pressure to the upper end of the circuit board is fixedly installed on the rack 6. The guide rod 4 guides the rack 6 so that the rack 6 can smoothly pull the movable platform 10 when it moves.
[0022] Both the bracket 3 and the guide rod 4 are vertically arranged. The fixed platform 5 and the moving platform 10 are concave structures. By setting the fixed platform 5 and the moving platform 10 as concave structures, the fixed platform 5 and the moving platform 10 can clamp the circuit board at both ends. The bracket 3 is fixedly installed with a motor 7, and the output end of the motor 7 is fixedly connected to a rotating shaft 8 that is connected to the rack 6 for transmission. The fixed platform 5 and the moving platform 10 are fixedly installed with a telescopic rod 11, and the output end of the telescopic rod 11 is fixedly connected to a pressure plate 12 that moves against the end of the circuit board. The fixed platform 5 can support the lower end of the circuit board, the moving platform 10 can apply pressure to the circuit board from the top position, and the pressure plate 12 can press the circuit board from the front position, so that the stability of the circuit board after being limited is guaranteed.
[0023] The fixed platform 5, the movable platform 10, and the pressure plate 12 are provided with soft pads 13 that move against the circuit board. The rotating shaft 8 is horizontally set, and a gear 9 that meshes with the rack 6 is fixedly installed on the rotating shaft 8. The pressure plate 12 is horizontally set on one side of the circuit board. By providing soft pads 13 on the fixed platform 5, the movable platform 10, and the pressure plate 12, the circuit board will not be excessively squeezed when it is clamped.
[0024] The output end of the telescopic rod 14 is fixedly connected to a frame 15, and a column 16 corresponding to the circuit board is placed inside the frame 15. A sealing plate 17 and a hollow frame 18 that fit with the circuit board are fixedly installed on the column 16. The frame 15 is vertically set on one side of the bracket 3. By moving the frame 15, it can gradually approach the bracket 3, so that the column 16 drives the sealing plate 17 and the hollow frame 18 to fit with the circuit board.
[0025] The frame 15 has a groove for storing the column 16. The hollow frame 18 has a U-shaped structure and corresponds to the hole in the circuit board. A lower plate is installed on the frame 15, and positioning posts extending into the frame 15 and the column 16 are fixedly installed on the lower plate. By installing the lower plate on the frame 15, the lower plate can drive the positioning posts to extend into the frame 15 and the column 16 respectively, thereby clamping the two ends of the column 16.
[0026] In addition, by installing the column 16, the column 16 drives the sealing plate 17 to correspond to the un-drilled part of the circuit board, and the column 16 drives the hollow frame 18 to correspond to the drilled part of the circuit board. This ensures that when the circuit board is drilled, both sides of the drilled part are in a supported state, thus preventing the circuit board from breaking at the drilled part.
[0027] A sealing structure for intercepting the circuit board is installed on the base 1.
[0028] The sealing structure includes two rotating rods 19 fixedly mounted on the base 1, and a support plate 20 is rotatably mounted on the rotating rods 19. A partition plate 21 for intercepting the circuit board is fixedly mounted on the support plate 20.
[0029] A telescopic rod 22 is fixedly installed on the base 1, and a connecting rod 23 is connected between the output end of the telescopic rod 22 and the support plate 20. The partition plate 21 is vertically set on both sides of the circuit board. The two ends of the connecting rod 23 are respectively connected to the output end of the telescopic rod 22 and the middle pin of the support plate 20. The position of the partition plate 21 can be adjusted by telescopically extending the output end of the telescopic rod 22. By setting symmetrical partition plates 21 on the base 1, the partition plates 21 can intercept the circuit board from both sides, thereby intercepting debris.
[0030] It should be noted that the specific models and specifications of the punch head 2, motor 7, telescopic rod one 11, telescopic rod two 14, and telescopic rod three 22 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation methods adopt existing technology in this field, so they will not be elaborated here.
[0031] The functional principle of this utility model can be explained through the following operation methods:
[0032] The lower end of the circuit board is placed in the fixed platform 5. The output end of the motor 7 drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the gear 9 to pull the meshing rack 6. When the rack 6 slides on the guide rod 4, it drives the moving platform 10 to move down, so that the moving platform 10 can clamp the upper end of the circuit board from the top position.
[0033] The extension and retraction of the output end of the telescopic rod 11 drives the pressure plate 12 to move horizontally, so that the pressure plate 12 presses the circuit board when it moves.
[0034] Press the column 16 into the groove according to the position of the hole in the circuit board, so that the column 16 drives the hollow frame 18 to correspond to the rear of the hole in the circuit board. Install the column 16 with the sealing plate 17 so that the sealing plate 17 can correspond to the rear of the circuit board. Press the lower plate so that the lower plate drives the positioning column to extend into the frame 15 and the column 16 respectively.
[0035] The retraction of the output end of the telescopic rod 14 drives the frame 15 to be pulled, so that the frame 15 gradually moves closer to the bracket 3. The frame 15 drives the sealing plate 17 and the hollow frame 18 to fit against the back of the circuit board.
[0036] The telescopic rod 22 retracts to pull the connecting rod 23. The position difference generated by the deflection of the connecting rod 23 can pull the support plate 20. The support plate 20 drives the partition plate 21 to intercept the circuit board from both sides. After the drilling head 2 is powered on, it can drill holes in the circuit board. The partition plate 21 can protect the operator next to the base 1.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
