[0002] Flexible printed circuit boards (FPCs) are circuit boards with flexible substrates as their core, capable of bending, folding, and twisting, while also providing signal and current transmission functions. They are mainly suitable for smaller applications. Flexible structures, on the other hand, are made by combining flexible materials and designing specific structures to allow specific areas of the FPC to be repeatedly bent, folded, and twisted without compromising electrical performance. In the processing of some flexible printed circuit boards, reinforcement is required to improve the strength of designated areas. Laser drilling equipment is used to drill micro-holes on the surface of flexible printed circuit boards.
[0003] In the prior art, when processing flexible circuit boards, reinforcements need to be installed on the flexible structure of the flexible circuit board first, and then the flexible circuit board is laser-drilled.

[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0019] like Figure 1 , Figure 2 and Figure 3As shown, the present invention proposes an in-mold laser micro-drilling device for reinforcing the flexible structure of flexible circuit boards, comprising a processing table 1, a cover 2 fixedly connected to one side of the top of the processing table 1, which isolates the drilling process from the outside by setting the cover 2, a drive frame 3 installed on the inner wall of the cover 2, and a laser drilling machine 4 installed on the drive frame 3. By setting the drive frame 3, the position of the laser drilling machine 4 can be changed as needed. A mounting frame 5 is fixedly connected to the other side of the top of the processing table 1, a first hydraulic rod 6 is fixedly connected to the bottom of the mounting frame 5, and a hot pressure plate 7 is fixedly connected to the output end of the first hydraulic rod 6. The first hydraulic rod 6 is used to drive the hot pressure plate 7 to move up and down. A mold plate 8 is set at the top of the processing table 1, and the mold plate 8 is used to place the flexible circuit board.
[0020] like Figure 2 - Figure 6As shown, the transfer assembly of the laser micro-drilling device is used to move the position of the mold plate 8, facilitating the transfer of the reinforced flexible circuit board to the inside of the housing 2. The transfer assembly includes a vacuum generator 14 and a suction pipe 12. The suction pipe 12 is used to fix the position of the flexible circuit board. The transfer assembly also includes a servo motor 9, which is fixed to the bottom of the inner wall of the processing table 1. The output end of the servo motor 9 is fixed to a turntable 10. After the flexible circuit board is hot-pressed by the hot press, the servo motor 9 can be driven to run, and the servo motor 9 drives the turntable 10 to rotate. When the turntable 10 rotates, the positions of the two sets of mold plates 8 change until the set of mold plates 8 containing the hot-pressed flexible circuit board moves to below the laser drilling machine 4. The cover 2 can be briefly opened via the control component to allow the mold plates 8 to enter the cover 2. The mold plates 8 are fixed to the top of the turntable 10, and the laser drilling machine 4 is activated to drill holes in the surface of the flexible circuit board. Two sets of mold plates 8 are provided and symmetrically distributed at the top of the turntable 10. The vacuum generator 14 is installed at the bottom of the turntable 10, and one end of the vacuum generator 14 is fixedly connected to a transmission pipe 13. The top of 13 is fixed to the bottom of the suction pipe 12, which is installed on the bottom of the inner wall of the mold plate 8. A mesh plate 11 is fixed inside the mold plate 8. When the vacuum generator 14 is activated, the air inside the mold plate 8 is sucked downward through the suction pipe 12 and the transmission pipe 13. At the same time, the suction force can fix the position of the flexible circuit board on the mesh plate 11, and the dust generated during cutting is also sucked away by the suction force. A slot is opened on one side of the mold plate 8, and a sealing plate 15 is inserted into the inner wall of the slot. By setting the sealing plate 15, when it is necessary to install reinforcement on the flexible circuit board, the flexible circuit board and the reinforcement can be connected. The flexible circuit board is placed inside the mold plate 8. Since the mold plate 8 has a sealing plate 15 inserted inside, the bottom of the flexible circuit board will contact the sealing plate 15. At this time, the first hydraulic rod 6 pushes the hot pressing plate 7 downward and hot-presses and solidifies the flexible circuit board and reinforcement on the sealing plate 15 until the flexible circuit board and reinforcement are firmly connected. The sealing plate 15 is set at the top of the mesh plate 11. A handle is fixed to one side of the sealing plate 15. Then, by pulling the handle, the sealing plate 15 is pulled out from the slot, so that the bottom of the flexible circuit board is placed on the mesh plate 11 inside the mold plate 8, which facilitates the drilling of the flexible circuit board.
[0021] like Figure 3 , Figure 4 and Figure 6As shown, the blocking component of the laser micro-drilling device is used to prevent small particles generated during cutting from clogging the suction pipe 12. A side pipe is fixed to the bottom of the transmission pipe 13. The blocking component includes a collecting cylinder 16, which is inserted into the inner wall of the transmission pipe 13 via the side pipe. A collecting groove is formed at the top of the collecting cylinder 16. A filter plate 17 is fixed to the end of the collecting cylinder 16 near the vacuum generator 14. By setting the side pipe and the collecting cylinder 16, when the vacuum generator 14 sucks the dust generated during drilling into the transmission pipe 13, the dust is filtered by the filter plate 17 on one side of the collecting cylinder 16, preventing dust from entering the vacuum generator 14. A pull block 19 is fixed to the end of the collecting cylinder 16 away from the vacuum generator 14. A cylinder 18 is fixed to the outer wall of the side pipe, and a magnet 20 is fixed to the inner wall of the cylinder 18. An iron block 21 is fixed to one side of the collecting cylinder 16. The iron block 21 is inserted into the inner wall of the cylinder 18, and the magnet 20 is attracted to one side of the iron block 21. By setting the magnet 20 inside the cylinder 18, when the collecting cylinder 16 is inserted into the side tube, the iron block 21 on the collecting cylinder 16 is simultaneously inserted into the cylinder 18, and the iron block 21 is attracted and fixed by the magnet 20 inside the cylinder 18. When it is necessary to clean the dust in the collecting cylinder 16, the pulling block 19 can be pulled to pull the collecting cylinder 16 out from the transmission pipe 13 and the side tube, and the iron block 21 is moved away from one side of the magnet 20 by the pulling force. A take-out groove is provided on one side of the processing table 1. The take-out groove is set on one side of the pulling block 19. A sealing plate 45 is rotatably connected to one side of the take-out groove via a rotating shaft. By setting the take-out groove, when it is necessary to take out the cylinder 18, the sealing plate 45 can be flipped open, and then the pulling block 19 can be pulled to take out the cylinder 18 from the side tube and the transmission pipe 13.
[0022] like Figure 7 , Figure 8 and Figure 10As shown, the top of the processing table 1 has a mounting groove 22, and a second hydraulic rod 23 is fixedly connected to the mounting groove 22. A push plate 24 is fixedly connected to the output end of the second hydraulic rod 23, and a frame plate 25 is fixedly connected to the top of the push plate 24. A conveyor belt 26 is installed inside the frame plate 25. The conveyor belt 26 is located on one side of the hot press plate 7. When it is necessary to transport the flexible circuit board to a set of mold plates 8, a set of flexible circuit boards is first placed on the conveyor belt 26, and the push plate 24 and the frame plate 25 are pushed to one side by activating the second hydraulic rod 23. When the frame plate 25 moves, it will drive the conveyor belt 26 to move together until the conveyor belt 26 moves to one side of the mold plate 8. Then, the flexible circuit board can be transported to the mold plate 8 by activating the conveyor belt 26. The cleaning component of the laser micro-drilling device is used to clean the surface of the flexible circuit board before processing to prevent impurities from affecting the processing. The cleaning component includes a support frame. 27. The support frame 27 is fixed to the top of the processing table 1. A third hydraulic rod 28 is fixed to the bottom of one side of the support frame 27. A frame 30 is fixed to the output end of the third hydraulic rod 28. When it is necessary to clean the surface of the flexible circuit board, the third hydraulic rod 28 can be activated to push the frame 30 downward. A rotary motor 31 is fixed to one side of the frame 30. A cleaning cylinder 32 is fixed to the output end of the rotary motor 31. The cleaning cylinder 32 is rotatably connected to the inner wall of the frame 30. The cleaning cylinder 32 is set at the top of the conveyor belt 26. When the frame 30 moves, it can drive the rotary motor 31 and the cleaning cylinder 32 to move downward together. When the surface of the cleaning cylinder 32 contacts the top of the flexible circuit board, the rotary motor 31 can be activated to drive the cleaning cylinder 32 to rotate. When the cleaning cylinder 32 rotates, it can wipe away the impurities on the surface of the flexible circuit board, so that the surface of the flexible circuit board can be kept clean during hot pressing.
[0023] like Figure 8 - Figure 12As shown, the cleaning assembly also includes a first gear 33, which is fixedly connected to the end of the cleaning cylinder 32. A second gear 34 meshes with one side of the first gear 33. A reciprocating screw 35 is fixedly connected to the center of the second gear 34. The reciprocating screw 35 is rotatably connected to the inner wall of the frame 30, and a nut 36 is threadedly connected to the outer wall of the reciprocating screw 35. When the cleaning cylinder 32 rotates, it drives the first gear 33 at one end to rotate together. The first gear 33 then drives the second gear 34 and the reciprocating screw 35, which are meshed on one side, to rotate together. When the reciprocating screw 35 rotates, it causes the nut 36 on its outer wall to move. A connecting rod 37 is fixedly connected to the top of the nut 36, and a mounting cylinder 38 is fixedly connected to one side of the connecting rod 37. When the nut 36 moves, it will drive the connecting rod 37 and the mounting cylinder 38 to move together. The top of the frame 30 has an elongated groove, and the mounting cylinder 38 is slidably connected to the inner wall of the elongated groove. Sliding grooves are formed on both sides of the elongated groove, and sliders 41 are fixedly connected to both sides of the mounting cylinder 38. The sliders 41 are slidably connected to the inner wall of the sliding groove. Since the mounting cylinder 38 is slidably disposed in the elongated groove of the frame 30, and the sliders 41 on both sides of the mounting cylinder 38 are also slidably disposed in the sliding groove, the mounting cylinder 38, the connecting rod 37, and the nut 36 can be connected together. The movement trajectory is limited to keep the mounting cylinder 38 and nut 36 moving in a straight line. A filter layer 39 is fixed to the top of the mounting cylinder 38, and a fan 40 is fixed to the bottom of the filter layer 39. When the mounting cylinder 38 moves, the fan 40 inside it can be activated, generating an upward suction force. Since the bottom of the fan 40 is located at the top of the cleaning cylinder 32, it can suck up impurities adsorbed on the surface of the cleaning cylinder 32 and pass them through the filter layer 39. Due to the characteristics of the reciprocating screw 35, the mounting cylinder 38 reciprocates at the top of the cleaning cylinder 32, thereby increasing the cleaning area. The connecting rod... A side rod 42 is fixedly connected to one side of the connecting rod 37, and an arc-shaped block 43 is fixedly connected to the bottom of the side rod 42. By setting the side rod 42 and the arc-shaped block 43 on one side of the connecting rod 37, the side rod 42 and the arc-shaped block 43 can be driven to move together when the connecting rod 37 moves back and forth. A scraper 44 is fixedly connected to the bottom of the arc-shaped block 43. The arc-shaped block 43 is set at the top and bottom of the cleaning cylinder 32. Since the scraper 44 is set at the bottom of the arc-shaped block 43, the arc-shaped block 43 will scrape off the impurities attached to the top of the cleaning cylinder 32 when it moves, so that the blower 40 can suck the scraped impurities into the filter layer 39.
[0024] like Figure 5As shown, the control component of the laser micro-drilling device is used to control the opening and closing of the housing 2. The control component includes an arc plate 46, which is fixed to the top of the turntable 10. The arc plate 46 is located on one side of the mold plate 8. The bottom of the housing 2 has two sets of openings. The inner wall of the opening is rotatably connected to a closing door 47 via a rotating shaft. When the turntable 10 rotates, it will drive the arc plate 46 to move together. Since the arc plate 46 is on one side of the mold plate 8, it can first contact the closing door 47 and lift the closing door 47, so that the mold plate 8 can enter the housing 2 as the turntable 10 rotates. Then, the other side of the arc plate 46 can lift the closing door 47, so that the closing door 47 gradually moves downward and hangs on one side of the opening by gravity, closing the opening. When removing the arc plate 46, the arc plate 46 can also lift the other set of closing doors 47, so that the drilled flexible circuit board can be removed from the housing 2.
[0025] Working Principle: To address the cumbersome processing of flexible printed circuit boards (FPCBs), when reinforcement is required, a set of FPCBs can be placed on conveyor belt 26. The second hydraulic rod 23 is then activated to push the push plate 24 and frame plate 25 to one side. As the frame plate 25 moves, it drives the conveyor belt 26 to move as well, until the conveyor belt 26 reaches one side of the mold plate 8. The FPCBs can then be transported to the mold plate 8 by activating the conveyor belt 26. When cleaning the surface of the FPCBs is required, the third hydraulic rod 28 is activated, which lowers the frame 30. As the frame 30 moves, it drives the rotary motor 31 and the cleaning cylinder 32 downwards together. When the surface of the cleaning cylinder 32 contacts the top of the flexible circuit board, the rotary motor 31 is activated to rotate the cleaning cylinder 32. The rotation of the cleaning cylinder 32 removes impurities from the surface of the flexible circuit board, keeping it clean during hot pressing. The rotation of the cleaning cylinder 32 also drives the first gear 33 at one end to rotate, which in turn drives the second gear 34 and the reciprocating screw 35 meshing on one side to rotate. The rotation of the reciprocating screw 35 then drives its outer wall... When the nut 36 moves, it will drive the connecting rod 37 and the mounting cylinder 38 to move together. Since the mounting cylinder 38 is slidably disposed in the long groove of the frame 30, and the sliders 41 on both sides of the mounting cylinder 38 are also slidably disposed in the groove, the movement trajectory of the mounting cylinder 38, the connecting rod 37 and the nut 36 can be limited, so that the mounting cylinder 38 and the nut 36 keep moving in a straight line. When the mounting cylinder 38 moves, the fan 40 installed inside it can be activated, and the fan 40 generates an upward suction force. Since the bottom of the fan 40 is located at the top of the cleaning cylinder 32, it can lift the cleaning cylinder 32. 2. Impurities adsorbed on the surface are drawn upwards and adsorbed through the filter layer 39. Due to the characteristics of the reciprocating screw 35, the mounting cylinder 38 moves back and forth at the top of the cleaning cylinder 32, thereby increasing the cleaning area. By setting a side rod 42 and an arc block 43 on one side of the connecting rod 37, the side rod 42 and the arc block 43 can move together when the connecting rod 37 moves back and forth. Since the bottom of the arc block 43 is provided with a scraper 44, the arc block 43 will scrape off the impurities attached to the top of the cleaning cylinder 32 when it moves, so that the fan 40 can suck the scraped impurities into the filter layer 39. The flexible circuit board is then placed inside the mold plate 8. By setting the sealing plate 15, when reinforcement needs to be installed on the flexible circuit board, the flexible circuit board and the reinforcement can be placed inside the mold plate 8. Since the sealing plate 15 is inserted inside the mold plate 8, the bottom of the flexible circuit board will contact the sealing plate 15. At this time, the hot press plate 7 is pushed downward by the first hydraulic rod 6. When the hot press plate 7 contacts the flexible circuit board, the reinforcement structure is installed on the flexible circuit board under the action of high temperature and pressure until the connection between the flexible circuit board and the reinforcement is stable. After the flexible circuit board is hot-pressed in the hot press, the closing plate 15 is pulled out of the slot by pulling the handle, so that the bottom of the flexible circuit board is placed on the mesh plate 11 in the mold plate 8, which facilitates drilling of the flexible circuit board. Then, the servo motor 9 is driven to run, and the servo motor 9 drives the turntable 10 to rotate. When the turntable 10 rotates, it changes the position of the two sets of mold plates 8. When the turntable 10 rotates, it drives the arc plate 46 to move together. Since the arc plate 46 is on one side of the mold plate 8, it can be moved through the arc plate. 46 first contacts the closed door 47 and lifts it up, allowing the mold plate 8 to enter the housing 2 as the turntable 10 rotates. Then, the other side of the arc plate 46 lifts the closed door 47, causing it to gradually move downwards and close the opening by gravity, until the set of mold plates 8 containing the hot-pressed flexible circuit board moves to below the laser drilling machine 4. The laser drilling machine 4 is then activated to drill holes in the surface of the flexible circuit board, while the vacuum generator 14 is activated to lift the mold plate 8. Air inside the cutting board 8 is drawn downwards through the suction pipe 12 and the transmission pipe 13. Simultaneously, the suction force fixes the flexible circuit board to the mesh board 11. Dust generated during cutting is also sucked away by the suction. By installing a magnet 20 inside the cylinder 18, when the collecting cylinder 16 is inserted into the side pipe, the iron block 21 on the collecting cylinder 16 is simultaneously inserted into the cylinder 18, and the magnet 20 inside the cylinder 18 attracts and fixes the iron block 21. By setting up the side pipe and the collecting cylinder 16, the dust generated during drilling can be removed by the vacuum generator 14. When the dust is sucked into the transmission pipe 13, it is filtered by the filter plate 17 on one side of the collection cylinder 16 to prevent it from entering the vacuum generator 14. When it is necessary to clean the dust in the collection cylinder 16, the sealing plate 45 can be opened and the pull block 19 can be pulled to pull the collection cylinder 16 out of the transmission pipe 13 and the side pipe. The iron block 21 is moved away from the side of the magnet 20 by the pulling force. When the arc plate 46 is taken out, another set of closed doors 47 can be lifted by the arc plate 46 to remove the drilled flexible circuit board from the cover 2.
