Description

Technical Field

[0001] This utility model relates to the field of protective film winding technology, specifically to a device for winding protective film for electronic components. Background Technology

[0002] Electronic component protective film is a thin film material used to protect the surface of electronic components from static electricity, dust contamination, and physical damage. After the electronic component protective film is processed, it needs to be wound up with the help of winding equipment. The electronic component protective film winding device is a device used for efficient winding and coating of protective film. It ensures the flatness of the protective film and reduces static electricity accumulation through a specific structural design.

[0003] In response, Chinese patent application number CN202420222572.3 discloses a protective film winding device for electronic components, including a machine body and a smoothing device. Support rollers are rotatably connected to the surface of the machine body, and four support wheels are rotatably connected to the bottom of the machine body. The smoothing device is located on the side wall of the machine body and includes two support frames inserted into the inner wall of the machine body. A main roller is rotatably connected to the surface of each support frame, and a main threaded rod is rotatably connected to the surface of each support frame. A placement block is threadedly connected to the surface of the main threaded rod. The moving device includes a connecting plate, with its two sides fixedly connected to the side walls of the two support frames respectively. Two auxiliary threaded rods are threadedly connected to the inner wall of the connecting plate. By setting up the support frames, main rollers, and auxiliary rollers, the protective film can be supported and guided. Simultaneously, the clamping plate and placement plate can smooth the protective film, reducing wrinkles during winding that could affect subsequent use.

[0004] The device smooths the protective film by setting up clamping plates and placement plates. However, the clamping plates and placement plates are relatively fixed and do not have a traction effect on the protective film. As a result, the wrinkles cannot be unfolded to both sides, and the wrinkles are pressed more obviously after entering between the clamping plates and placement plates, which greatly limits the use of the device.

[0005] Therefore, in order to solve the above problems, a device for winding up protective film for electronic components is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a device for winding up protective film for electronic components, in order to solve the problem mentioned in the background art that the existing device smooths the protective film by setting up a clamping plate and a placement plate. However, the clamping plate and the placement plate are relatively fixed and have no traction effect on the protective film. As a result, the wrinkles cannot be unfolded to both sides, and the wrinkles are pressed more obviously after entering between the clamping plate and the placement plate, which makes the use of the device very limited.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an electronic component protective film winding device, comprising: a machine body, wherein a winding roller is mounted on the front side of the machine body;

[0008] A groove is provided on the left end of the bottom surface of the body, and a guide block is installed on the inner side of the groove;

[0009] A movable structure is installed on the left side of the machine body. The movable structure includes a movable frame, which is movably installed on the left side of the machine body. A fixed block is fixedly installed on the right end of the bottom surface of the movable frame. A guide groove is opened on the right side wall of the fixed block. A bracket is installed on the top surface of the movable frame. A sliding groove is opened on the surface of the bracket. A threaded rod is movably installed on the inner side of the sliding groove through a bearing. A transmission wheel is fixedly connected to the upper end of the threaded rod. A hand-rotating transmission rod is movably installed on the top surface of the bracket through a bearing. A pad is slidably installed on the inner side of the sliding groove. Rotating shafts are movably installed on both sides of the top surface of the pad through bearings. A spiral friction strip is adhered to the outer wall of the rotating shaft. A motor is fixedly installed on the top surface of the pad.

[0010] Preferably, the right end of the movable frame is inserted into the inner side of the groove, the guide block is inserted into the guide slot, and the guide block is adapted to the guide slot.

[0011] Preferably, the threaded rod passes through the pad and is threadedly connected to the pad.

[0012] Preferably, the hand-rotating transmission rod meshes with the transmission wheel, and the hand-rotating transmission rod is adapted to the transmission wheel.

[0013] Preferably, the rotating shaft is installed at an angle, and the bottom surface of the spiral friction strip is in contact with the top surface of the pad.

[0014] Preferably, the output end of the motor is fixedly connected to the rotating shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by setting an inclined rotating shaft, the rotating shaft can drive the spiral friction strip to rotate when it rotates. When the spiral friction strip rotates, it can pull the two sides of the protective film, so that the wrinkles on the protective film can be unfolded to both sides to eliminate the wrinkles and make the protective film roll up smoothly.

[0016] This invention features a movable structure. Pushing the movable frame moves it to the left side of the machine body, then pushing it to the right causes the guide block's end to extend beyond the left side wall of the machine body. As the movable frame approaches the machine body, the guide block is inserted into the guide groove, providing guidance for the movement of the movable frame within the groove. This allows the right end of the movable frame to move into the machine body, preventing back-and-forth displacement between the movable structure and the machine body during winding, which would affect the smooth winding of the protective film. Rotating the hand-operated transmission rod engages with two sets of transmission wheels. The rotation of the hand-operated transmission rod drives the screw through the transmission wheels. The threaded rod rotates, connecting to the pad plate. The rotation of the threaded rod causes the pad plate to move up and down inside the groove, adjusting its position and height to ensure smooth transmission of the protective film between the pad plate and the take-up roller, reducing the transmission angle. Starting the motor drives the rotating shaft, which in turn rotates the spiral friction strip. The protective film is positioned between the pad plate and the rotating shaft, with the bottom of the spiral friction strip adhering to it. As the spiral friction strip rotates, it pulls the protective film forward and backward, unfolding the wrinkles and eliminating them, preventing wrinkles from accumulating and spreading, thus allowing the protective film to be wound up smoothly.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 An embodiment of the electronic component protective film winding device provided by this utility model:

[0024] The machine body 1, winding roller 11 and motor 212 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0025] An electronic component protective film winding device includes: a body 1, and a winding roller 11 is mounted on the front side of the body 1;

[0026] A groove 12 is provided on the left end of the bottom surface of the body 1, and a guide block 13 is installed on the inner side of the groove 12;

[0027] A movable structure 2 is installed on the left side of the body 1. The movable structure 2 includes a movable frame 21, which is movably installed on the left side of the body 1. A fixing block 22 is fixedly installed on the right end of the bottom surface of the movable frame 21. A guide groove 23 is provided on the right side wall of the fixing block 22. A bracket 24 is installed on the top surface of the movable frame 21. A sliding groove 25 is provided on the surface of the bracket 24. A threaded rod 26 is movably installed on the inner side of the sliding groove 25 through a bearing. A transmission wheel 27 is fixedly connected to the upper end of the threaded rod 26. A drive wheel 27 is movably installed on the top surface of the bracket 24 through a bearing. A pad 29 is slidably installed on the inner side of the hand-rotating transmission rod 28 and the slide groove 25. A rotating shaft 210 is movably installed on both sides of the top surface of the pad 29 through bearings. A spiral friction strip 211 is adhered to the outer wall of the rotating shaft 210. A motor 212 is fixedly installed on the top surface of the pad 29. When the rotating shaft 210 rotates, it can drive the spiral friction strip 211 to rotate. When the spiral friction strip 211 rotates, it can pull the two sides of the protective film, so that the wrinkles on the protective film are unfolded to both sides to eliminate the wrinkles and allow the protective film to be rolled up flat.

[0028] Furthermore, the right end of the movable frame 21 is inserted into the inner side of the groove 12, and the guide block 13 is inserted into the guide groove 23. The guide block 13 is adapted to the guide groove 23. The groove 12 provides a position for the connection between the movable frame 21 and the body 1. The guide block 13 cooperates with the guide groove 23 to provide guidance for the connection between the movable frame 21 and the body 1.

[0029] Furthermore, the threaded rod 26 passes through the pad 29 and is threadedly connected to the pad 29. The rotation of the threaded rod 26 can drive the pad 29 to move up and down.

[0030] Furthermore, the hand-rotating transmission rod 28 meshes with the transmission wheel 27, and the hand-rotating transmission rod 28 is adapted to the transmission wheel 27. The rotation of the hand-rotating transmission rod 28 can drive the threaded rod 26 to rotate through the pad 29.

[0031] Furthermore, the rotating shaft 210 is installed at an angle, and the bottom surface of the spiral friction strip 211 is in contact with the top surface of the pad 29. The rotating shaft 210 can drive the spiral friction strip 211 to rotate, and the rotation of the spiral friction strip 211 can pull the two sides of the protective film, causing the wrinkles on the protective film to unfold.

[0032] Furthermore, the output end of the motor 212 is fixedly connected to the rotating shaft 210, and the motor 212 provides power for the rotation of the rotating shaft 210.

[0033] Working principle: When in use, push the movable frame 21 to move it to the left side of the machine body 1, and then push the movable frame 21 to the right. The end of the guide block 13 extends out of the left side wall of the machine body 1. When the movable frame 21 approaches the machine body 1, the guide block 13 will be inserted into the guide groove 23 first. The guide block 13 cooperates with the guide groove 23 to provide guidance for the movement of the movable frame 21 inside the groove 12. This allows the right end of the movable frame 21 to move into the machine body 1, which can prevent the movable structure 2 from shifting in the front and back direction between the machine body 1 during winding, thus affecting the flat winding of the protective film.

[0034] Rotate the hand-operated transmission rod 28, which meshes with two sets of transmission wheels 27. The rotation of the hand-operated transmission rod 28 drives the threaded rod 26 to rotate through the transmission wheels 27. The threaded rod 26 is threadedly connected to the pad plate 29. The rotation of the threaded rod 26 drives the pad plate 29 to move up and down inside the slide groove 25. The position and height of the pad plate 29 can be adjusted to make the protective film transfer between the pad plate 29 and the take-up roller 11 smooth and reduce the transfer angle.

[0035] When the motor 212 is started, the motor 212 can drive the rotating shaft 210 to rotate, which in turn drives the spiral friction strip 211 to rotate. The protective film is located between the pad 29 and the rotating shaft 210, and the bottom of the spiral friction strip 211 is attached to the protective film. When the spiral friction strip 211 rotates, it can pull the protective film forward and backward, so that the wrinkles on the protective film are unfolded, so as to eliminate the wrinkles and prevent the wrinkles from accumulating and expanding, so that the protective film can be rolled up flat.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
