Description

Technical Field

[0001] The utility model relates to the technical field of protective film winding, in particular to a winding device for an electronic component protective film. Background Art

[0002] Protective films can be classified into electronic component protective films, automotive protective films, household protective films, food preservation protective films, etc. according to their uses. Among them, electronic component protective films are widely used in the surface material protection and prevention of static electricity generation during the production processes of FPC, PCB and electronic components. During the production and processing of existing protective films, it is necessary to wind the protective films.

[0003] The current winding devices lack positioning and effective tensioning. Therefore, during winding, winding skew and wrinkles are likely to occur, resulting in the non-flatness of the wound protective film, and the edges of the wound protective film are relatively messy, affecting the subsequent processing quality. Content of the Utility Model

[0005] For this reason, an object of the utility model is to provide a winding device for an electronic component protective film to solve the problems mentioned in the background art and overcome the deficiencies existing in the prior art.

[0006] To achieve the above object, an embodiment of one aspect of the utility model provides a winding device for an electronic component protective film, including a bottom plate. On both sides of one side edge of the top surface of the bottom plate, support ears are fixedly connected. The centers of the tops of the two support ears are jointly rotatably connected with an inlet roller. On one side edge of the middle part of the top surface of the bottom plate, a support plate is fixedly connected. The center of the top of the support plate is rotatably connected with a rotating shaft. One end of the rotating shaft is fixedly connected with a connecting plate. On both sides of the connecting plate, tensioning rollers are rotatably connected. The two tensioning rollers are symmetrically arranged with the axis of the rotating shaft as the symmetry center. One end of the rotating shaft penetrates outside the support plate and is fixedly connected with a spring fixing plate. A coil spring is sleeved on one side of the rotating shaft close to the spring fixing plate. The two ends of the coil spring are respectively fixedly connected with the spring fixing plate and the connecting plate. At the position corresponding to the connecting plate on the middle part of the top surface of the bottom plate, a guiding channel is fixedly connected. The center of the inner wall of the guiding channel is rotatably connected with a bidirectional transmission lead screw. On both sides of the surface of the bidirectional transmission lead screw, support columns are threadedly connected through positive and negative threads. The support columns are slidably connected with the inner wall of the guiding channel. The top of the support column is fixedly connected with a connecting frame. In the inner walls of the two connecting frames, rotating disks are rotatably connected. On both sides of the two rotating disks, connecting holes are opened. The two tensioning rollers are respectively rotatably connected with two connecting holes of the two rotating disks. On the edge of the side of the top surface of the bottom plate away from the support ears, a winding assembly is fixedly connected.

[0007] Preferably, according to any of the above solutions, the winding assembly includes two support arms. On one side of the top of each of the two support arms, an auxiliary roller is rotatably connected. On the other side of the top surface of each of the two support arms, a driving roller is rotatably connected. The auxiliary rollers and the driving rollers are symmetrically arranged and have the same size. A winding roller is mounted between the auxiliary roller and the driving roller.

[0008] The technical effect achieved by adopting the above solution is that the winding roller can be supported by the auxiliary roller and the driving roller, and the driving roller can drive the winding roller to rotate and wind, while facilitating the taking and placing of the winding roller.

At the center of the axis of the driving roller, a connecting shaft is fixedly connected. On one side of the connecting shaft, a driven sprocket is fixedly connected. A transmission chain is commonly connected to the outer walls of the driving sprocket and the driven sprocket.

[0010] The technical effect achieved by adopting the above solution is that when the transmission shaft rotates, the two driving rollers can be driven to rotate synchronously through the driving sprocket, the driven sprocket and the transmission chain.

[0011] Preferably, according to any of the above solutions, on one side of the transmission shaft, a driven worm gear is fixedly connected. On one side of the top surface of the bottom plate close to the driven worm gear, a fixed ear is fixedly connected. At the center of the fixed ear, a driving worm is rotatably connected.

[0018] For this electronic component protective film winding device, by rotating the two tension rollers around the rotating shaft, the two tension rollers can rotate and wind the protective film tightly. Driven by the winding force of the coil spring, the two tension rollers rotate to wind the protective film tightly, so that the protective film is tensioned and remains flat during winding. At the same time, by rotating the bidirectional transmission lead screw, the two support columns can be driven to slide closer or farther away from each other, thereby adjusting the distance between the two rotating disks to adapt to protective films of different widths. By blocking both sides of the protective film with the two rotating disks, the two sides of the protective film can be limited, thus preventing skew during winding, improving the flatness of winding, and enhancing the winding effect.

[0030] An electronic component protective film winding device has the following working principle:

[0031] 1) The protective film is introduced through between the two tensioning rollers 6 by the guiding roller 3, and then wound and fixed on the surface of the winding roller 24;

[0032] 2) Then, the two tensioning rollers 6 rotate around the rotating shaft 25, so that the two tensioning rollers 6 can rotate and wind the protective film tightly. The two tensioning rollers 6 are driven to rotate and wind the protective film tightly by the winding force of the coil spring 8, so that the protective film is tensioned and kept flat during winding;

[0033] 3) By rotating the bidirectional transmission lead screw 11, the two support columns 12 can be driven to slide closer to or away from each other, so as to adjust the distance between the two rotating disks 15 to adapt to protective films of different widths. The two sides of the protective film are limited by the two rotating disks 15 shielding the two sides of the protective film, so as to prevent skewing during winding.

[0034] 4) Then, the driving worm 27 is driven to rotate by the reduction motor 28, and then the transmission shaft 17 is driven to rotate synchronously. The driven sprocket 21 and the driving roller 19 are driven to rotate through the driving sprocket 18 and the transmission chain 22, so as to drive the winding roller 24 to rotate and wind the protective film.

[0035] In summary, for the winding device of the electronic component protective film, by rotating the two tension rollers 6 around the rotating shaft 25, the two tension rollers 6 can rotate and wind the protective film tightly. The winding force of the torsion spring 8 drives the two tension rollers 6 to rotate and wind the protective film tightly, so that the protective film is tensioned and remains flat during winding. At the same time, by rotating the bidirectional transmission lead screw 11, the two support columns 12 can be driven to slide closer to or away from each other, so as to adjust the distance between the two rotating discs 15 to adapt to protective films of different widths. The two rotating discs 15 block both sides of the protective film, so as to limit both sides of the protective film, thereby preventing skew during winding, improving the flatness of winding, and enhancing the winding effect.
