They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] 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.

[0022] Reference Figure 1-3A precision winding machine for cleaning lint brush rollers for circuit boards includes a base 1, a control box 2 at the upper left end of the base 1, and a fixing plate 3 fixedly connected to the upper right end of the base 1. The control box 2 has a cavity 4 inside, and a drive assembly is provided inside the cavity 4. The drive assembly includes a servo motor 8 fixedly installed on the bottom left side of the cavity 4. A rotating shaft 9 is fixedly connected to the drive shaft of the servo motor 8, and a first gear 10 is coaxially fixedly connected to the rotating shaft 9. The servo motor 8 is used to drive the first gear 10 on the rotating shaft 9 to rotate. The first gear 10 is connected to a positioning assembly for transmission.

[0023] A positioning assembly is rotatably installed on the right inner wall of cavity 4. The positioning assembly includes a rotating rod 11 that is horizontally rotatably installed on the right inner wall of cavity 4. The rotating rod 11 is rotatably connected to the left inner wall of cavity 4. A first positioning head 12 is fixedly connected to one end of the rotating rod 11 outside cavity 4. A second gear 13 and a drive wheel 14 are coaxially fixedly connected to the rotating rod 11. The first gear 10 meshes with the second gear 13, and the first gear 10 drives the meshing second gear 13 to rotate, so that the second gear 13 drives the coaxially connected rotating rod 11 to rotate, and the rotating rod 11 drives the first positioning head 12 to rotate. The drive wheel 14 is connected to the sliding screw 5 to transmit power. A sliding screw 5 is horizontally rotatably mounted on the right inner wall of the control box 2 near the top surface. Both the drive assembly and the sliding screw 5 are connected to the positioning assembly. The left end of the sliding screw 5 is rotatably connected to the left inner wall of the control box 2. The end of the sliding screw 5 located inside the control box 2 is coaxially fixedly connected to a driven wheel 15. The drive wheel 14 and the driven wheel 15 are connected by a belt drive. The rotation of the rotating rod 11 drives the coaxially connected drive wheel 14 to rotate, which in turn drives the belt-driven driven wheel 15 to rotate, and the driven wheel 15 drives the coaxially connected sliding screw 5 to rotate. A movable guide block 6 is threaded onto the sliding screw 5.

[0024] The upper end of the movable guide block 6 is fixedly connected to an unwinding mechanism. The unwinding mechanism includes a bracket 16 fixedly connected to the upper end of the movable guide block 6. A drive motor 17 is fixedly installed on the left side wall of the bracket 16 near the upper end. A first limiting wheel 18 is horizontally rotatably mounted on the bracket 16. The drive motor 17 is used to drive the first limiting wheel 18 to rotate, so that the first limiting wheel 18 can drive the pile strip to advance smoothly. The drive shaft of the drive motor 17 rotates horizontally through the bracket 16 and is fixedly connected to the wheel axle of the first limiting wheel 18. A limiting block 19 is fixedly connected to the lower end of the movable guide block 6. A limiting rod 20 is fixedly connected between the control box 2 and the fixed plate 3. The limiting rod 20 is horizontally mounted through the limiting block 19. The sliding screw 5 rotates to drive the movable guide block 6 to move horizontally under the limiting action of the limiting block 19 and the limiting rod 20.

[0025] A winding limiting mechanism is provided on the front side wall of the movable guide block 6. The winding limiting mechanism includes a connecting plate 21 fixedly connected to the front side wall of the movable guide block 6. An L-shaped block 22 is fixedly connected to the right side wall of the connecting plate 21 near the lower end. Two second limiting wheels 23 are horizontally rotatably connected between the vertical section side wall of the L-shaped block 22 and the connecting plate 21. The two second limiting wheels 23 are respectively located near the upper and lower ends of the L-shaped block 22. A positioning block 24 is fixedly connected to the side wall of the L-shaped block 22 between the two second limiting wheels 23. The positioning block 24 has an upper and lower communication device. The rectangular through groove 25 has ball bearings 26 embedded in the inner walls of both sides. The drive motor 17 on the starting bracket 16 drives the first limiting wheel 18 to rotate, so that the first limiting wheel 18 guides the pile strip to be wound to the two second limiting wheels 23 between the connecting plate 21 and the L-shaped block 22, and passes the pile strip through the rectangular through groove 25 on the positioning block 24 between the two second limiting wheels 23. This allows the pile strip to be smoothly wound and fixed on the brush roller with the help of the two second limiting wheels 23 and the ball bearings 26, thereby improving the winding effect of the pile strip.

[0026] A support base 7 is fixedly connected to the upper end of the base 1 near the fixed plate 3. An adjustment component is horizontally rotatable between the fixed plate 3 and the support base 7. The adjustment component includes a threaded rod 27 with a horizontal thread passing through the fixed plate 3 and the support base 7. A second positioning head 28 is fixedly connected to the left end of the threaded rod 27. The second positioning head 28 is directly opposite the first positioning head 12. A turntable 29 is fixedly connected to the right end of the threaded rod 27. One end of the brush roller is placed on the first positioning head 12. The turntable 29 is rotated in conjunction with the threaded rod 27 to adjust the relative position of the second positioning head 28 and the first positioning head 12 until the brush roller can be clamped and positioned between the first positioning head 12 and the second positioning head 28. This facilitates quick positioning of the brush roller. The structure is simple and practical.

[0027] In use, one end of the brush roller is placed on the first positioning head 12. The turntable 29 is rotated in conjunction with the threaded rod 27 to adjust the relative position of the second positioning head 28 and the first positioning head 12 until the brush roller can be clamped and positioned between the first positioning head 12 and the second positioning head 28. This facilitates quick and easy positioning of the brush roller. The structure is simple and practical. According to actual needs, the winding parameters are adjusted by the control box 2. The servo motor 8 is started to drive the first gear 10 on the rotating shaft 9 to rotate, which in turn drives the meshing second gear 13 to rotate. The second gear 13 drives the coaxially connected rotating rod 11 to rotate, which in turn drives the first positioning head 12 to rotate, thus causing the clamped and positioned brush roller to rotate. On the other hand, the rotation of the rotating rod 11 drives the coaxially connected drive wheel 14 to rotate, which in turn drives the belt-driven drive wheel 14 to rotate. The driven wheel 15 rotates, causing it to drive the coaxially connected sliding screw 5 to rotate. At this time, the rotation of the sliding screw 5 drives the movable guide block 6 to move horizontally under the limiting action of the limiting block 19 and the limiting rod 20. During the movement of the movable guide block 6, the drive motor 17 on the start bracket 16 drives the first limiting wheel 18 to rotate, so that the first limiting wheel 18 guides the long strip of fluff to be wound to the two second limiting wheels 23 between the connecting plate 21 and the L-shaped block 22, and passes the long strip of fluff through the rectangular through slot 25 on the positioning block 24 between the two second limiting wheels 23. This allows the long strip of fluff to be smoothly wound and fixed on the brush roller in conjunction with the two second limiting wheels 23 and the ball bearing 26, improving the winding effect of the long strip of fluff. When the winding reaches the predetermined length, the winding machine is stopped, and necessary checks and adjustments are made to ensure that the long strip of brush bristles can be precisely wound on the brush roller.

[0028] 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.
