[0001] The present invention relates to the technical field of semiconductor manufacturing, and particularly relates to a tape winding and unwinding device. Background Art

[0002] With the rapid development of electronic product technology, Chip on Film (COF) products are increasingly widely used due to their many advantages such as being thin, light, and highly reliable.

[0003] At present, COF products usually adopt the tape automatic bonding technology for production. The tape reel with COF chips is installed on the unwinding shaft, and one end of the tape is fixed to the winding shaft. The tape is transmitted by the rotation of the unwinding shaft and the winding shaft. However, during the production process, the reel often deforms, resulting in a smaller distance between the two side plates. When the tape touches the side plate of the reel, the tape jamming phenomenon occurs, causing the situation that the tape cannot be smoothly wound into the reel, affecting the normal winding and unwinding of the tape. Summary of the Invention

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "front", "rear", "upper", "lower", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] Refer to Figure 1 and Figure 2As shown in the figure, in an embodiment of the present invention, a tape winding and unwinding device 100 is provided, which includes a reel 10 and a support assembly 20. The tape can be wound and accommodated on the reel 10. The reel 10 includes a central shaft 11 and two side plates 12 oppositely arranged in the axial direction of the central shaft 11. A gap for accommodating the tape is formed between the two side plates 12. The support assembly 20 includes an adjusting rod 21 connected to the central shaft 11, a movable member 22 movably engaged with the adjusting rod 21 along the axial direction, and at least two connecting arms 23.

[0028] Wherein, the connecting arm 23 has a connecting portion 231 connected to the movable member 22 and an engaging portion 232 connected to the edge of the side plate 12. The movable member 22 can move along the adjusting rod 21 in the axial direction and act on the side plate 12 through the connecting arm 23 to adjust the minimum distance between the two side plates 12.

[0029] Specifically, the reel 10 has a first side plate 121 and a second side plate 122 arranged oppositely, and the connecting arm 23 can be connected to the first side plate 121. Of course, in some embodiments, the connecting arm 23 can also be connected to the second side plate 122. In this application, the case where the connecting arm 23 is connected to the first side plate 121 is described. During the axial movement of the movable member 22 along the adjusting rod 21, the connecting arm 23 can define the position of the edge of the first side plate 121 in the axial direction of the central shaft 11. For example, during the movement of the movable member 22 along the adjusting rod 21 away from the reel 10, through the action of the connecting arm 23 on the first side plate 121, the position of the edge of the first side plate 121 in the axial direction of the central shaft 11 moves outward to change the distance between the first side plate 121 and the second side plate 122.

[0030] During the working process of the tape winding and unwinding device 100, the movable member 22 can move along the adjusting rod 21 in the axial direction away from the reel 10, and increase the minimum distance between the first side plate 121 and the second side plate 122 through the connecting arm 23 to solve the problem of tape jamming during winding due to the deformation of the side plate 12 of the reel 10, which helps to reduce the occurrence of tape breakage and damage, can ensure smooth tape winding, and helps to improve production capacity.

[0031] In this embodiment, the connecting arms 23 can be set to four, and the four connecting arms 23 are evenly arranged around the axis of the adjusting rod 21. That is, the included angle formed between two adjacent connecting arms 23 is 90 degrees, so that the side plate 12 can be deformed evenly, and the distance between the edges of the two side plates 12 can be kept consistent.

[0032] Such as Figure 3As shown, the connecting arm 23 can be connected to the first side plate 121 through a hook structure. The engaging portion 232 includes a hook body 2321, a hook tongue 2322, and a transition section 2323 connecting the hook tongue 2322 and the hook body 2321. A fitting gap 2324 for engaging the edge of the side plate 12 is formed between the hook body 2321 and the hook tongue 2322. The engaging portion 232 can be engaged with the edge of the first side plate 121 through the fitting gap 2324 to realize the connection between the engaging portion 232 and the edge of the first side plate 121. Of course, in some embodiments, the connecting arm 23 can also be connected to the first side plate 121 through a structure such as a suction cup.

[0033] As Figure 4 and Figure 5 shown, a threaded transmission connection can be provided between the adjusting rod 21 and the movable member 22. The adjusting rod 21 has a threaded section 211, and the movable member 22 is provided with a threaded hole 226 that cooperates with the threaded section 211. The adjusting rod 21 passes through the threaded hole 226 and axially moves while rotating relative to the movable member 22, capable of adjusting the axial position of the movable member 22, and further capable of acting on the first side plate 121 through the connecting arm 23 to increase the minimum distance between the first side plate 121 and the second side plate 122.

[0034] Furthermore, one end of the adjusting rod 21 passes through the threaded hole 226 and abuts against the central shaft 11. The threaded hole 226 can be arranged coaxially with the central shaft 11, that is, the adjusting rod 21 and the central shaft 11 are coaxially arranged. The adjusting rod 21 includes an abutting portion 212 and a cross portion 213, and the abutting portion 212 and the cross portion 213 are respectively located at both ends of the adjusting rod 21. The abutting portion 212 can abut against the central shaft 11, and the cross portion 213 can be held by a user to rotate the adjusting rod 21.

[0035] Even further, the side plate 12 of the material tray 10 is integrally arranged in a disc shape, and the maximum radial distance from any two of the engaging portions 232 to the threaded hole 226 is the same. During the rotation of the adjusting rod 21, each part of the first side plate 121 can deform uniformly, so that the distance between the first side plate 121 and the second side plate 122 can increase relatively uniformly.

[0036] During the operation of the tape winding and unwinding device 100, the abutting portion 212 abuts against the central shaft 11. The user can rotate the adjusting rod 21 through the cross portion 213 to adjust the position of the movable member 22, and then stretch the first side plate 121 through the connecting arm 23, so that the minimum distance between the first side plate 121 and the second side plate 122 is increased, facilitating the smooth accommodation of the tape into the tray 10.

[0037] In this embodiment, the connecting portion 231 is rotatably connected to the movable member 22 about a direction perpendicular to the axial direction, that is, the connecting arm 23 is rotatably connected to the movable member 22. During the movement of the movable member 22 along the adjusting rod 21, the connecting arm 23 can rotate relative to the movable member 22 to ensure that the connecting arm 23 is always connected to the side plate 12 to stretch the side plate 12 and increase the distance between the edges of the two side plates 12.

[0038] As Figure 1 、 Figure 5 and Figure 6 shown, the movable member 22 includes a body 221 and a connecting shaft 222 provided on the body 221. The connecting arm 23 is provided with a mounting hole 2311 for the connecting shaft 222 to pass through, thereby enabling the connecting arm 23 to rotate relative to the movable member 22.

[0039] Further, the body 221 is provided with an assembly hole 223 and a positioning hole 224 communicating with the assembly hole 223. The connecting shaft 222 is installed in the assembly hole 223. The movable member 22 further includes a positioning body 225. The positioning body 225 can be installed in the positioning hole 224 to abut against the connecting shaft 222, thereby enabling the fixing of the connecting shaft 222 and preventing the connecting shaft 222 from detaching from the assembly hole 223.

[0040] Optionally, the positioning body 225 can be provided with components such as a stop screw or a positioning pin. Therefore, any solution that can achieve the fixation of the connecting shaft 222 relative to the body 221 can be adopted by the present invention.

[0041] In this embodiment, the tape winding and unwinding device 100 further includes a mounting bracket 30 for mounting the tray 10. The central shaft 11 includes a reel 112 for winding the tape and a mounting shaft 31 connecting the reel 112 and the mounting bracket 30. The tray 10 can be rotatably connected to the mounting bracket 30 through the mounting shaft 31, and the support assembly 20 rotates synchronously with the tray 10.

[0042] Among them, the abutting portion 212 of the adjusting rod 21 can abut against the mounting shaft 31. During the rotation of the material tray 10 relative to the mounting frame 30, the support assembly 20 rotates synchronously with the material tray 10 to ensure the smoothness of the tape winding and receiving process.

[0043] Further, the material tray 10 further includes a stopper 32 mounted on the mounting shaft 31. An assembly gap 33 for mounting the reel 112 is formed between the stopper 32 and the mounting frame 30, so that the reel 112 can be fixed to the mounting shaft 31. The installation of the stopper 32 and the connection manner between the mounting shaft 31 and the mounting frame 30 are prior arts and will not be elaborated herein.

[0044] In summary, the beneficial effects of the present invention are as follows: The tape winding and unwinding device 100 can solve the problem of tape jamming during material receiving or discharging caused by the deformation of the material tray 10 by expanding the distance between the two side plates 12 of the material tray 10, improve the quality of the tape product, reduce the occurrence of tape folding defects, ensure the smoothness of tape receiving or discharging, and help improve production capacity.

This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
