Description

Technical Field

[0001] This utility model relates to the field of FPC circuit board technology, and in particular to an auxiliary material cleaning device for drilling FPC circuit boards. Background Technology

[0002] Flexible circuit boards (FPCs) are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate. They are characterized by high wiring density, light weight, thinness, and good bending properties. However, the CVL (continuous ductile) lining material used for FPC drilling is composed of polyimide and adhesive, which causes severe tangling after drilling.

[0003] Existing technologies, such as the FPC circuit board drilling auxiliary material cleaning device disclosed in CN116489891A, include an operating table, a fixed platform fixedly connected to the upper end of the operating table, a mounting frame fixedly connected to the upper end of the fixed platform, an L-shaped frame slidably arranged on one side of the mounting frame, a second cylinder fixedly connected to the upper end of the L-shaped frame, and two air pipes with their lower ends movably penetrating through the inner top wall of the mounting frame. A high-pressure air pump, mounting pipe, connecting bucket, air inlet, and air pipes work together to blow high-pressure gas through the air inlet into the airflow channel. The high-pressure gas passing through the airflow channel can blow away the CVL auxiliary material wrapped around the drilling head, quickly cleaning the wrapped wire and avoiding the risk of tool breakage during manual cleaning. However, the following problems still exist in its use:

[0004] The above technology uses high-pressure gas to blow away the CVL auxiliary material filaments. However, the CVL auxiliary material filaments blown out by high-pressure gas are not easy to collect and are easily blown to all sides. Cleaning requires cleaning the device and its surroundings, resulting in a waste of labor. Utility Model Content

[0022] 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.

[0023] Reference Figures 1-6 A device for cleaning auxiliary materials for drilling FPC circuit boards includes a base plate 1 and an FPC board 9. Two pairs of symmetrically arranged fixing rods 2 are fixedly installed on the upper part of the base plate 1, and a drilling platform 3 is fixedly installed on the two pairs of fixing rods 2. The FPC board 9 is placed on the upper part of the drilling platform 3, and a cleaning roller 8 for cleaning the auxiliary materials on the upper part of the FPC board 9 is arranged directly above the FPC board 9. A collection groove 12 for collecting the auxiliary materials cleaned by the cleaning roller 8 is arranged at the bottom of the drilling platform 3. A mounting frame 13 is fixedly installed on the upper part of the base plate 1 relative to the right side of the drilling platform 3. A first cylinder 14 is fixedly installed on the upper end of the mounting frame 13, and a second cylinder 15 is fixedly installed on the bottom of the first cylinder 14. A drilling device is fixedly installed on the bottom end of the second cylinder 15.

[0024] The drilling device includes a mounting cylinder 16 fixedly installed at the bottom of the second cylinder 15. The mounting cylinder 16 has a hollow structure, and a rotating motor 17 is fixedly installed inside the cavity of the mounting cylinder 16. A take-up roller 18 is fixedly installed at the output end of the rotating motor 17. Four equidistantly distributed fixed frames 20 are fixedly installed on the outer wall of the mounting cylinder 16. A sliding plate 21 is slidably arranged inside the fixed frame 20. A spring 22 is fixedly installed on one side of the sliding plate 21, and a tension rope 19 is fixedly installed on the other side of the sliding plate 21. A drilling motor 27 is fixedly installed at the bottom of the mounting cylinder 16. A drilling head 26 is fixedly installed at the output end of the drilling motor 27. A cleaning ring 25 is sleeved on the outer wall of the drilling head 26. A connecting rod 24 is arranged between the cleaning ring 25 and the fixed frame 20, and both ends of the connecting rod 24 are rotatably connected to sliding seats 23 through pins.

[0025] One end of the tension rope 19 is wrapped around the outer wall of the take-up roller 18, one end of the spring 22 is fixedly installed on the fixed frame 20, the upper end of the connecting rod 24 is rotatably connected to the sliding seat 23 through the pin and is fixedly installed on the outer wall of the sliding plate 21 relative to the lower part of the tension rope 19, and the lower end of the connecting rod 24 is rotatably connected to the sliding seat 23 through the pin and is fixedly installed on the outer wall of the cleaning ring 25.

[0026] The drilling platform 3 is fixedly installed with fixed columns 4 on both sides, and the fixed column 4 is fixedly installed with baffles 5 at the ends. The baffles 5 block the auxiliary material splashed during the rotation of the cleaning roller 8 and make it fall into the collection tank 12.

[0027] Two symmetrically arranged slide rails 6 are fixedly installed on the upper part of the drilling table 3. Sliding blocks 7 are slidably arranged on the slide rails 6, and the cleaning roller 8 is rotatably arranged between the two sliding blocks 7.

[0028] Two electric telescopic rods 10 are fixedly installed on the inner walls of both sides of the drilling platform 3. The ends of the electric telescopic rods 10 are fixedly installed with clamping plates 11 for holding the FPC board 9.

[0029] The functional principle of this utility model can be explained through the following operation methods:

[0030] By placing the FPC board 9 on the drilling table 3, and then extending and retracting the electric telescopic rod 10, the electric telescopic rod 10 pushes the clamping plate 11 towards the FPC board 9 to fix the FPC board 9 and prevent the FPC board 9 from moving during drilling, thus affecting the drilling accuracy. Then, the first cylinder 14 pushes the second cylinder 15, causing the second cylinder 15 to drive the drilling head 26 to the position on the upper part of the FPC board 9 where a hole needs to be drilled. Then, the second cylinder 15 pushes the mounting cylinder 16 downward, so that the bottom of the drilling head 26 contacts the upper part of the FPC board 9. Then, the drilling motor 27 is turned on, causing the drilling head 26 to drill a hole in the FPC board 9. When CVL auxiliary material is wound on the drilling head 26, the rotating motor 17 is driven to drive the take-up roller 18 to rotate, causing the take-up roller 18 to wind up the tension rope 19, so that the tension rope... 19. Pull the sliding plate 21 to slide within the fixed frame 20, causing the fixed frame 20 to push the sliding seat 23, causing the connecting rod 24 to deflect around the sliding seat 23, which is rotatably connected to the bottom of the connecting rod 24. This causes the angle between the upper surface of the connecting rod 24 and the outer wall of the punch head 26 to gradually decrease, thereby causing the connecting rod 24 to push the cleaning ring 25 downward. The cleaning ring 25 then presses down the CVL auxiliary material wrapped around the outer wall of the punch head 26, eventually causing it to fall off from the bottom of the punch head 26 onto the upper part of the FPC board 9. Then, through the extension and retraction of the spring 22, the cleaning ring 25 returns to its original position, facilitating subsequent cleaning of the punch head 26. When the CVL auxiliary material falls off onto the upper part of the FPC board 9, the slider 7 slides on the slide rail 6, causing the cleaning roller 8 to clean the CVL auxiliary material on the upper part of the FPC board 9, causing the CVL auxiliary material to fall into the collection trough 12 for easy collection.

[0031] 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.
