Description

Technical Field

[0001] The utility model relates to the technical field of chip-on-chip film reels, in particular to a detachable reel used for chip-on-chip films. Background Art

[0002] During the production process of chip-on-film, in order to facilitate later storage and transportation, the produced chip-on-film needs to be rolled up on a reel. When installing the existing chip-on-film reel, the reel is mainly fixed and disassembled manually with bolts, thereby realizing the disassembly and assembly of the reel and the rotating shaft. This disassembly and assembly method is relatively cumbersome and difficult to meet the needs of automated assembly and disassembly (that is, the reel is disassembled and assembled by a robot, thereby reducing the labor intensity of workers). Therefore, in view of the above problems, a detachable reel for chip-on-film is designed to better meet the actual use needs. Utility Model Content

[0003] The utility model aims to provide a detachable reel for chip-on-film to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a detachable reel for chip-on-chip film, comprising a reel, on which a convex cylinder is fixed symmetrically on the left and right, the convex cylinder and the reel are connected to a rotating shaft, a movable ring plate is connected to the outer side of the convex cylinder, and four positioning rods are connected to the convex cylinder at equal angles.

[0005] Preferably, baffles are fixed symmetrically on the reel, and the diameter of the baffles is larger than the outer diameter of the reel. The baffles can limit the chip-on-film when it is rolled up, thereby ensuring the neatness of the chip-on-film rolling.

[0006] Preferably, the rotating shaft is slidably connected to the reel and the convex cylinder, and a limiting ring is fixed on the rotating shaft, and the limiting ring contacts the convex cylinder to achieve a limiting effect. The sliding effect between the rotating shaft, the reel and the convex cylinder can facilitate the disassembly and assembly of the rotating shaft, the reel and the convex cylinder, and the limiting effect of the limiting ring can limit the free position of the rotating shaft, the reel and the convex cylinder.

[0007] Preferably, the movable ring plate and the convex cylinder are slidably connected, and one end of a spring is fixed to the side of the movable ring plate close to the baffle, and the other end of the spring is fixed to the baffle. At the same time, there are six springs distributed at equal angles about the center of the movable ring plate. Through the elastic action of the spring, a basic force can be provided for the automatic reset of the movable ring plate to ensure the normal use of the device.

[0008] Preferably, the positioning rod and the convex cylinder are slidably connected, and the positioning rod and the rotating shaft are snap-fitted. Through the snap-fit ​​action between the positioning rod and the rotating shaft, the rotating shaft, the reel and the convex cylinder can form an integrated structure, thereby ensuring the normal operation of the device.

[0009] Preferably, one end of the connecting rod is rotatably connected to the positioning rod, and the other end of the connecting rod is rotatably connected to the movable ring plate. When the movable ring plate moves, the transmission action of the connecting rod can provide a basic force for the movement of the positioning rod.

[0010] Compared with the prior art, the beneficial effects of the utility model are: the detachable reel applied to the chip-on-film adopts a movable elastic snap-fit ​​positioning installation structure instead of a transmission bolt fastening installation structure, which can facilitate the disassembly and assembly between the reel and the rotating shaft, improve the convenience of disassembly and assembly of the reel, and realize the disassembly and assembly by driving the movable ring plate to move by an external manipulator, thereby better meeting the automation requirements of reel disassembly and assembly, and effectively reducing the labor intensity of workers.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-Figure 3 The utility model provides a technical solution: a detachable reel for chip-on-film, comprising a reel 1, a convex cylinder 2 fixed symmetrically on the reel 1, the convex cylinder 2 and the reel 1 are connected to a rotating shaft 3, a movable ring plate 4 is connected to the outer side of the convex cylinder 2, and four positioning rods 5 are connected to the convex cylinder 2 at equal angles.

[0017] A baffle 101 is also fixed symmetrically on the reel 1, and the diameter of the baffle 101 is larger than the outer diameter of the reel 1; the positioning rod 5 is slidably connected to the convex cylinder 2, and the positioning rod 5 is snap-fitted to the rotating shaft 3; one end of the connecting rod 6 is rotatably connected to the positioning rod 5, and the other end of the connecting rod 6 is rotatably connected to the movable ring plate 4;

[0018] When using the detachable reel for chip-on-film, Figure 1 As shown, the entire reel is in the installed state at this time, and the rotating shaft 3 is driven to rotate by the external driving mechanism, and the locking action between the positioning rod 5 and the rotating shaft 3 can make the convex cylinder 2 and the reel 1 rotate synchronously with the rotating shaft 3. At this time, the reel 1 can realize the winding of the chip-on-film, and the baffle 101 can realize the left and right limit of the chip-on-film, so as to ensure the neatness of the winding of the chip-on-film;

[0019] The rotating shaft 3 is slidably connected to the reel 1 and the convex cylinder 2, and a limit ring 301 is fixed on the rotating shaft 3, and the limit ring 301 contacts the convex cylinder 2 to achieve a limiting effect; the movable ring plate 4 is slidably connected to the convex cylinder 2, and one end of a spring 401 is fixed on the side of the movable ring plate 4 close to the baffle 101, and the other end of the spring 401 is fixed on the baffle 101, and six springs 401 are distributed at equal angles about the center of the movable ring plate 4; one end of a connecting rod 6 is rotatably connected to the positioning rod 5, and the other end of the connecting rod 6 is rotatably connected to the movable ring plate 4;

[0020] After the chip-on-film is rolled up, when the reel is disassembled, Figure 1-Figure 3 As shown, at this time, it is only necessary to clamp the left and right movable ring plates 4 respectively by two manipulators, and apply a force by the manipulators to make the left and right movable ring plates 4 move toward each other. At this time, the distance between the movable ring plates 4 is reduced, and the spring 401 is forced to shrink, and the sliding effect between the movable ring plate 4 and the convex cylinder 2 can ensure the stability of the movement of the movable ring plate 4. When the movable ring plate 4 moves, the connecting rod 6 is forced to rotate. Through the transmission effect of the connecting rod 6, the positioning rod 5 can be forced to slide toward the outside of the convex cylinder 2 until the positioning rod 5 is separated from the rotating shaft 3 to release the locking effect. Finally, the entire reel is driven to move to the right by the manipulator to realize the separation of the rotating shaft 3 from the reel 1 and the convex cylinder 2, thereby realizing the disassembly of the reel. The installation of the entire reel can also be realized according to the above-mentioned separation. During the installation process, when the limit ring 301 contacts the convex cylinder 2, the limit of the entire reel can be realized, and then the movable ring plate 4 is loosened by the manipulator, and the elastic action of the spring 401 can make the movable ring plate 4 reset, so that the positioning rod 5 is engaged with the rotating shaft 3 to achieve positioning, thereby ensuring the stability of the reel after installation. This is the working principle of the detachable reel applied to chip-on-film.
