[0030] In this embodiment:

[0031] Reference Figure 1-5 The diagram shows a preferred embodiment of the present invention.

[0032] The FPC laminating equipment of this embodiment includes an FPC laminating and coating machine 1. A circular shaft 4 is symmetrically connected to the inner wall of the FPC laminating and coating machine 1. A conveyor belt 5 is sleeved and connected to the outer surface of the circular shaft 4. A first motor 6 is fixedly connected to one side of one of the conveyor belts 5. One side of the first motor 6 is fixedly connected to one side of the FPC laminating and coating machine 1. A limit roller 7 is rotatably connected to the inner wall of the FPC laminating and coating machine 1. A hot press roller 9 is provided on the inner wall of the FPC laminating and coating machine 1. A cutter 10 is provided on the inner wall of the FPC laminating and coating machine 1. A circular rod 8 is connected to one side of the FPC laminating and coating machine 1. A second motor 12 is fixedly connected to one end of the circular rod 8. One side of the second motor 12 is fixedly connected to one side of the FPC laminating and coating machine 1. A limit plate 11 is provided on one side of the FPC laminating and coating machine 1. A cleaning device 2 is provided on the top of the FPC laminating and coating machine 1. When using the FPC laminating machine 1 to laminate the surface of an FPC printed circuit board, the laminating roll is first fixed on the round rod 8. Then, one end of the laminating roll is passed through the limiting roller 7 and fixed. The FPC printed circuit board is then placed on the conveyor belt 5, with one side tightly against the side of the limiting plate 11. The first motor 6 is then started to drive the round shaft 4 to rotate, thereby driving the conveyor belt 5 to convey the FPC printed circuit board. When it is conveyed to a certain position, the cleaning device 2 cleans the surface of the FPC printed circuit board, removing the dust and impurities attached to its surface to prevent the dust from affecting the subsequent laminating process. Then, it continues to be conveyed. When it reaches the bottom of the limiting roller 7, the drive mechanism inside the FPC laminating machine 1 is started to drive the limiting roller 7 and the hot press roller 9 to rotate, pressing the laminating film onto the surface of the FPC printed circuit board. Finally, the cutting machine 10 cuts off the excess laminating film to complete the processing.

[0033] This embodiment discloses a cleaning device 2 including a grooved frame 21. An electric telescopic rod 22 is fixedly connected to one side of the inner wall of the grooved frame 21. A bracket 23 is fixedly connected to the output rod of the electric telescopic rod 22. One end of the bracket 23 is slidably connected to the inner wall of the grooved frame 21. An air pump 24 is fixedly connected to one side of the grooved frame 21. A corrugated pipe 25 is fixedly connected to the outlet of the air pump 24. The corrugated pipe 25 is passed through and connected to one side of the grooved frame 21 and the bracket 23. An air guide frame 26 is fixedly connected to one end of the corrugated pipe 25. The outer surface of one end of the air guide frame 26 is fixedly connected to one side of the bracket 23. First, the electric telescopic rod 22 inside the groove frame 21 is activated, causing the bracket 23 to slide downwards to a certain position within the inner wall of the groove frame 21. This then moves the air guide frame 26 downwards to a certain position, stretching its corrugated pipe 25. The air guide frame 26 then drives the air pump 24 to draw external air into the corrugated pipe 25, which is then discharged through the air guide frame 26. When the conveyor belt 5 transports the FPC printed circuit board to a certain position, the air discharged from the air guide frame 26 blows away the dust adhering to its surface, cleaning the surface and preventing the dust from affecting subsequent lamination processing, thus improving the processing efficiency and product quality of the FPC printed circuit board. A limiting rod 28 is fixedly connected to one side of the bracket 23, with one end of the limiting rod 28 threaded through and connected to one side of the groove frame 21. By setting the limiting rod 28, one end of the bracket 23 can be limited and supported, preventing the end of the bracket 23 away from the electric telescopic rod 22 from wobbling during vertical movement. An auxiliary mechanism 27 is fixedly connected to one side of the bracket 23. The auxiliary mechanism 27 includes a sponge 272. Several connecting rods 271 are fixedly connected to one side of the bracket 23, and one end of each connecting rod 271 is fixedly connected to one side of the sponge 272. Before using the air pump 24 and the air guide frame 26 to clean the surface of the FPC printed circuit board with air, the sponge 272 can be used to remove the more firmly attached impurities and dust that are not easily blown away, making it easier to clean again later and improving the processing efficiency and product quality of the FPC printed circuit board.

[0034] Reference Figure 1-5As shown, this embodiment discloses a detachable device 3 provided between one side of the groove frame 21 and the top side of the FPC laminating machine 1. The detachable device 3 includes two U-shaped blocks 35. A first slot 31 is provided on the top side of the FPC laminating machine 1. A second slot 32 is provided on both sides of the inner wall of the first slot 31. One end of the groove frame 21 is inserted into the inner wall of the first slot 31. A sliding groove 33 is provided on both sides of one end of the groove frame 21. The inner wall of the sliding groove 33 is slidably connected to one end of the U-shaped block 35. A spring 34 is fixedly connected to one side of the inner wall of the sliding groove 33. One end of the spring 34 is fixedly connected to one side of the U-shaped block 35. One end of the U-shaped block 35 is inserted into the inner wall of the second slot 32. When maintenance or replacement of the air pump 24 and the air guide frame 26 is required, the U-shaped block 35 can be manually pressed inward into the inner wall of the slide groove 33 to a certain position, so that the spring 34 is compressed and the other end will be pulled out from the second slot 32. Then, one end of the groove frame 21 can be pulled out from the first slot 31, so that it can be removed from the FPC laminating machine 1 for easy replacement and maintenance.

[0035] This embodiment discloses that one end of the groove bracket 21 has a trapezoidal longitudinal section, and this trapezoidal end of the groove bracket 21 is located near the end of the U-shaped block 35. By setting one end of the groove bracket 21 to a trapezoidal shape, the area of ​​one end can be reduced, making it easier to quickly align with and insert into the inner wall of the first slot 31 during installation. A limiting telescopic rod 36 is fixedly connected to one side of the inner wall of the slide groove 33. One end of the limiting telescopic rod 36 is fixedly connected to one side of the U-shaped block 35, and the limiting telescopic rod 36 is sleeved and connected to the spring 34. By setting the limiting telescopic rod 36, the inner wall of the spring 34 can be supported and reinforced, making it less prone to damage during use and improving its service life.

[0036] This embodiment also discloses an FPC bonding structure, which is applied to the aforementioned FPC bonding equipment.

[0037] Working principle: When using the FPC laminating machine 1 to laminate the surface of an FPC printed circuit board, firstly, the electric telescopic rod 22 inside the groove frame 21 is activated, causing the bracket 23 to slide downwards to a certain position within the inner wall of the groove frame 21. This causes the air guide frame 26 to move downwards to a certain position, stretching its corrugated tube 25. This, in turn, drives the air pump 24 to draw external air into the corrugated tube 25, which is then discharged through the air guide frame 26. The laminating roll is then mounted and fixed on the round rod 8, with one end of the laminating roll passing through the limiting roller 7 and secured. The FPC printed circuit board is then placed on the conveyor belt 5, with one side pressed tightly against the side of the limiting plate 11. The first motor 6 is then activated, causing the round shaft 4 to rotate, which in turn drives the conveyor belt 5 to laminate the FPC printed circuit board. The circuit board is conveyed. When the conveyor belt 5 transports the FPC printed circuit board to a certain position, the sponge wipe 272 can be used to first clean away the relatively firmly attached impurities and dust that are not easily blown away. Then, the air discharged by the air guide frame 26 will blow away the dust attached to the surface, thus cleaning the surface and preventing the attached dust from affecting the subsequent lamination process. This improves the processing efficiency and product quality of the FPC printed circuit board. The board continues to be conveyed. When it reaches the bottom of the limiting roller 7, the drive mechanism inside the FPC laminating machine 1 is activated to drive the limiting roller 7 and the hot pressure roller 9 to rotate, and the lamination is applied and pressed onto the surface of the FPC printed circuit board. Finally, the cutting machine 10 cuts off the excess lamination to complete the processing.

[0038] When maintenance or replacement of the air pump 24 and the air guide frame 26 is required, the U-shaped block 35 can be manually pressed inward into the inner wall of the slide groove 33 to a certain position, so that the spring 34 and the limiting telescopic rod 36 are compressed, and the other end will be pulled out from the second slot 32. Then, one end of the groove frame 21 can be pulled out from the first slot 31, so that it can be removed from the FPC laminating machine 1 for easy replacement and maintenance.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
