Description

Technical Field

[0001] This utility model relates to the field of industrial manufacturing and automation equipment, and in particular to a flexible circuit board winding machine. Background Technology

[0002] Flexible printed circuit boards (FPCBs), also known as flexible circuit boards or flexible circuit boards, are printed circuit boards made using flexible insulating substrates. FPCBs offer excellent electrical performance, meeting the design needs for smaller and higher-density installations. They can be freely bent, rolled, and folded, and can be arranged arbitrarily according to spatial layout requirements, greatly reducing the size and weight of electronic products. They are suitable for the development of electronic products towards high density, miniaturization, and high reliability. They also have good heat dissipation performance, contributing to the stable operation of electronic products. However, existing FPCB winding machines suffer from circuit board misalignment during the winding process, leading to uneven winding. Uneven winding results in an unattractive finished product roll with jagged edges, affecting the overall visual effect. Furthermore, it may be more susceptible to damage during storage and transportation, such as edge wear, curling, and deformation. Uneven rolls can also cause packaging difficulties, increasing packaging material and transportation costs. Utility Model Content

[0003] To overcome the shortcomings of existing flexible circuit board rewinding machines in terms of uneven winding, the technical problem to be solved is to provide a flexible circuit board rewinding machine with high winding uniformity.

[0004] The technical solution of this utility model is as follows: a flexible circuit board winding machine, including a feeding rack, one end of which is fixedly connected to a mounting base, a sliding groove is provided on the mounting base, a feeding roller is rotatably connected to the mounting base, and a positioning mechanism for positioning the flexible circuit board is provided on the mounting base.

[0005] In one embodiment, the positioning mechanism includes a motor, which is fixedly connected to the mounting base. A double-ended screw is rotatably connected to the mounting base, and the output shaft of the motor is fixedly connected to the double-ended screw. A sliding plate is slidably connected to the mounting base, and the sliding plate is threadedly connected to the double-ended screw. Elastic elements are symmetrically fixedly connected to the sliding plate, one end of each elastic element is fixedly connected to the sliding plate, and the other end of each elastic element is fixedly connected to a positioning block. A positioning groove is formed in the middle of the positioning block, and a roller is rotatably connected to the positioning block. The positioning block is used to guide and position the flexible circuit board.

[0006] In one embodiment, the mounting base is provided with a swing mechanism to prevent the flexible circuit board from being too tight during winding. The swing mechanism includes a cylinder, which is fixedly connected to the mounting base. A rack is slidably connected to the mounting base and slides inside a groove. The telescopic rod of the cylinder is fixedly connected to the rack. A swing arm is rotatably connected to the mounting base. A U-shaped groove is formed at the top of the swing arm. A gear is fixedly connected to the swing arm and meshes with the rack. A collecting roller is mounted on the swing arm and slidably connected to the U-shaped groove. A buckle for fixing the collecting roller is rotatably connected to the top of the swing arm. The collecting roller can slide within the U-shaped groove. When the swing arm swings, the collecting roller can adjust its position within the U-shaped groove according to the swing amplitude.

[0007] In one embodiment, a brush is also included, with the brush fixedly connected to the mounting base.

[0008] In one embodiment, a guide wheel is also included, which is fixedly connected to the mounting base.

[0009] In one embodiment, a lighting lamp is also included, and the mounting base is fixedly connected to the lighting lamp.

[0010] Beneficial effects: 1. The rollers between the positioning blocks can reduce friction on the flexible circuit board and limit its movement. When the flexible circuit board is rolled off course, the positioning blocks on both sides can align the rolled circuit board. The elastic element can buffer the pressure of the positioning blocks on the circuit board, thereby preventing the flexible circuit board from being rolled unevenly.

[0011] 2. The cylinder drives the rack to move forward, the rack meshes with the gear, which drives the gear to rotate, and the gear drives the swing arm to swing, which plays the role of adjusting the position of the collecting roller, ensuring that it remains parallel to the surface of the flexible circuit board, and achieving the effect of adjusting uneven tension during winding.

[0012] 3. Cleaning the surface of the flexible circuit board with a brush can reduce dust on the surface of the flexible circuit board, thus preventing dust from damaging the flexible circuit board. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0018] Example: A flexible printed circuit board rewinding machine, such as Figure 1-3As shown, it includes a feeding rack 1, a mounting base 2, a feeding roller 3, and a positioning mechanism 4. One end of the feeding rack 1 is fixedly connected to the mounting base 2. The mounting base 2 has a sliding groove 201. The feeding roller 3 is rotatably connected to the mounting base 2. The mounting base 2 is provided with the positioning mechanism 4 for positioning the flexible circuit board. The positioning mechanism 4 includes a motor 401, a double-ended screw 402, a sliding plate 403, an elastic element 404, a positioning block 405, and a roller 406. The motor 401 is fixedly connected to the mounting base 2, and the double-ended screw 402 is rotatably connected to the mounting base 2. The output shaft of the motor 401 is fixedly connected to the double-ended screw 402. The sliding plate 403 is slidably connected to the mounting base 2 and threadedly connected to the double-ended screw 402. The elastic element 404 is symmetrically fixedly connected to the sliding plate 403. One end of the elastic element 404 is fixedly connected to the sliding plate 403, and the other end of the elastic element 404 is fixedly connected to the positioning block 405. The positioning block 405 has a groove 201 in the middle, and the roller 406 is rotatably connected to the positioning block 405. The positioning block 405 is used to guide and position the flexible circuit board. The mounting base 2 is equipped with a swing mechanism 5 to prevent the flexible circuit board from becoming too tight during winding. The swing mechanism 5 includes a cylinder 501, a rack 502, a swing arm 503, a gear 504, a collecting roller 505, and a buckle 8. The cylinder 501 is fixedly connected to the mounting base 2, and the rack 502 is slidably connected to the mounting base 2. The rack 502 slides inside the slide groove 201. The telescopic rod of the cylinder 501 is fixedly connected to the rack 502, and the swing arm 503 is rotatably connected to the mounting base 2. The top of the swing arm 503 has a U-shaped groove. A gear 504 is fixedly connected to the swing arm 503, and the gear 504 meshes with the rack 502. A collecting roller 505 is mounted on the swing arm 503 and slidably connected to the U-shaped groove. A buckle 8 for fixing the collecting roller 505 is rotatably connected to the top of the swing arm 503. The collecting roller 505 can slide within the U-shaped groove. When the swing arm 503 swings, the collecting roller 505 can adjust its position within the U-shaped groove according to the swing amplitude. A brush 6 is also included, fixedly connected to the mounting base 2. The brush 6 is used to clean the surface of the flexible circuit board and prevent dust from damaging it. The lighting lamp 9 provides sufficient light to improve operational safety. A guide wheel 7 is also included, fixedly connected to the mounting base 2. The guide wheel 7 is used to reduce the friction generated when the flexible circuit board is wound up.

[0019] First, the flexible circuit board to be wound is placed in the feeding roller 3, and then the starting end of the circuit board is pulled onto the collecting roller 505. Next, according to the actual winding requirements of the flexible circuit board, the winding speed, tension, and other parameters are set through the equipment's control system. At the same time, the positioning mechanism 4 is adjusted according to the width of the flexible circuit board. At this time, the motor 401 starts, driving the double-headed screw 402 connected to it to rotate. Because the sliding plate 403 is threadedly connected to the double-headed screw 402, when the double-headed screw 402 rotates, the sliding plate 403 will move synchronously along the sliding groove 201 on the mounting base 2, thereby driving the elastic element 404 and the positioning block 405 fixed below the sliding plate 403 to move together. When the positioning block 405 moves to the preset position, the motor 401 stops rotating, completing the adjustment of the positioning mechanism 4. Next, the starting end of the flexible circuit board passes under the brush 6, which cleans the surface of the circuit board, effectively removing dust and preventing scratches, short circuits, or other damage during subsequent winding. Then, the flexible circuit board passes the guide wheel 7. The guide wheel 7 reduces friction during circuit board movement, allowing for easier and smoother traction and preventing damage due to excessive friction. When the starting end of the flexible circuit board passes the roller 406 between the positioning blocks 405, the roller 406 not only reduces friction with the circuit board, allowing it to move forward more easily and complete winding, but also limits its movement during winding, ensuring it stays on the predetermined path. If the flexible circuit board deviates during winding, its sides will contact the positioning blocks 405, which will guide the circuit board back to the correct position. Furthermore, the elastic element 404 can buffer the pressure of the positioning block 405 on the circuit board, avoiding damage to the circuit board due to excessive pressure, thereby effectively preventing the flexible circuit board from being rolled up unevenly.During the winding process, if the collecting roller 505 deviates, it will affect the tension distribution of the material during winding, resulting in uneven tension and causing the flexible circuit board to deviate. At this time, the cylinder 501 is activated, and the telescopic rod of the cylinder 501 extends forward, driving the rack 502 connected to it to move forward within the slide groove 201 of the mounting base 2. Since the rack 502 meshes with the gear 504 on the swing arm 503, the movement of the rack 502 will drive the gear 504 to rotate, causing the swing arm 503 to swing. When the swing arm 503 swings, the collecting roller 505 can move within the swinging area. The U-shaped groove at the top of arm 503 automatically adjusts its position according to the swing amplitude, ensuring that the collecting roller 505 remains parallel to the surface of the flexible circuit board, thereby ensuring uniform tension distribution during winding. After the flexible circuit board is wound up, the collected flexible circuit board is removed from the collecting roller 505. When installing the collecting roller 505, it is first placed into the U-shaped groove on the swing arm 503, and then the buckle 8 is rotated to fix the collecting roller 505. The buckle 8 can prevent the collecting roller 505 from falling off during the winding process, avoiding the scrapping of the flexible circuit board due to the collecting roller 505 falling off, thereby reducing the wear and tear of the flexible circuit board.

[0020] like Figure 1 As shown, it also includes a lighting lamp 9, which is fixedly connected to the mounting base 2. The lighting lamp 9 is used for site lighting.

[0021] The lighting lamp 9 on the mounting base 2 can provide sufficient light for the winding operation site, improve visibility during operation, and thus enhance the safety of the operation.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
