[0033] In actual application, the movable end of the film 4 is connected with the chain 202 through the connecting piece 5, when the first driving member 201 is started, the second sprocket 205 rotates, because the chain 202 is arranged around the first sprocket 204 and the second sprocket 205 at the same time, the rotation of the second sprocket 205 drives the chain 202 to move, with the movement of the chain 202, the connecting piece 5 pulls the film 4 to move along the predetermined path, and the film 4 is arranged on the guide rollers 101 in turn, so as to complete automatic film threading, compared with manual film threading, the device improves the film threading efficiency, and avoids the problem of scratching and pollution of the guide rollers 101 during manual film threading.
[0034] Specifically, the support plate 1 is provided with a pay-off shaft 102 for fixing the film 4, one end of the pay-off shaft 102 is connected with the support plate 1, and the other end extends outward in parallel. In this embodiment, the support plate 1 is an inner wall of one side of a vacuum coating chamber, in use, the film 4 is sleeved on the outer periphery of the pay-off shaft 102, and it is ensured that the film 4 can rotate around the pay-off shaft 102. Then the movable end 401 of the film 4 is fixed on the chain 202 through the connecting piece 5, and then the first driving member 201 is started. At this time, the first sprocket 204 starts to rotate, because the chain 202 is connected with the first sprocket 204 and the second sprocket 205 in transmission, the chain 202 also starts to move. Because the film 4 can rotate freely around the pay-off shaft 102, therefore, with the movement of the chain 202, the movable end 401 of the film 4 will be gradually stretched, when the film 4 passes through the guide roller 101, the film 4 will be automatically arranged on the guide roller 101 under the action of its own tension and the guide of the guide roller 101, thereby, automatic film threading is realized.
[0035] With the above structure, the overall structure of the utility model is closely combined together, the first driving part 201 can drive the second sprocket 205 to rotate, and then the second sprocket 205 drives the chain 202 to move, so as to realize that the film 4 is put on the guide roller 101. The whole structure is simpler and safer, and can completely replace manual operation to put the film 4 on the guide roller 101 of the coating equipment.
[0036] In some embodiments of the utility model, the outer circumferential surface of the first sprocket 204 and the second sprocket 205 is provided with a groove 2041 extending in the circumferential direction, and the chain 202 is arranged in the groove 2041. The groove 2041 not only provides accurate guidance for the chain 202, but also enhances the contact area between the sprocket and the chain 202, thereby improving the stability and durability of the transmission. The chain 202 is embedded in these grooves 2041, forming a continuous and stable transmission path. When the first driving part 201 starts, it will drive the second sprocket 205 to rotate, and then drive the chain 202 to move smoothly along the groove 2041.
[0037] Please refer to Figure 3 It should be noted that the chain 202 of the embodiment includes a plurality of chain links 2021, and the plurality of chain links 2021 are connected end to end. The chain 202 is formed by connecting a plurality of chain links 2021 end to end, which ensures the continuity of the chain 202 during transmission and avoids transmission failure caused by chain 202 breakage or falling.
[0038] In some embodiments of the utility model, one end of the chain link 2021 is formed into a pointed end 2021a, and the pointed end 2021a points to the moving direction of the chain 202. The pointed end 2021a of the chain link 2021 points to the moving direction of the chain 202, so that the operator can quickly identify and understand the moving direction of the chain 202 and the film 4, thereby reducing the possibility of misoperation and failure. That is, setting one end of the chain link 2021 as the pointed end 2021a can make the chain link 2021 more prominent visually, so that the movement of the chain 202 is more conspicuous, which helps the operator to pay more attention to the running condition of the chain 202 when monitoring the equipment.
[0039] Further, please refer to Figure 4 In actual application, the device further includes at least one tensioning component 3, and the tensioning component 3 is arranged on the moving path of the chain 202. The tensioning component 3 can adjust the tightness of the chain 202, thereby ensuring that the chain 202 will not cause transmission failure or damage due to looseness or tightness during operation.
[0040] Specifically, the tensioning component 3 includes a tensioning wheel 301, a swing arm 302 and a second driving member 303. The tensioning wheel 301 is pressed on the chain 202.

The second driving member 303 provides power for the swing arm 302, thereby controlling the position and pressure of the tensioning wheel 301. When the chain 202 runs on the moving path, the tensioning wheel 301 maintains appropriate pressure on the chain 202 through the support of the swing arm 302 and the power of the second driving member 303. If the chain 202 is loose due to some reasons (such as load change, chain elongation, etc.), the second driving member 303 will drive the swing arm 302 to swing, so that the tensioning wheel 301 is pressed more tightly on the chain 202, thereby restoring the tension of the chain. Conversely, if the chain 202 is too tight, the second driving member 303 will adjust the position of the swing arm 302 accordingly to reduce the pressure of the tensioning wheel 301 on the chain 202.
[0041] It should be noted that in the present embodiment, the tensioning wheel 301, like the first sprocket 204 and the second sprocket 205, has a groove around the outer periphery of the tensioning wheel 301. In use, the chain 202 is embedded in the groove and can move along the groove,
[0042] In some embodiments of the present application, the connecting member 5 is a tape, one end of which is connected with the movable end 401, and the other end is connected with the chain 202. The tape is selected as the connecting member 5, which can simplify the structure of the automatic film threading device, reduce the number and complexity of parts, thereby reducing the manufacturing cost and maintenance difficulty. In use, only one end of the tape is adhered to the movable end 401 of the film 4, and the other end is adhered to the chain 202. When the chain 202 moves, the movable end 401 will be elongated, so that the film 4 is wound on the guide roller 101 in turn. In other embodiments, the connecting member 5 can also be selected as a buckle or other components, as long as it can fix the movable end 401 of the film 4 on the chain 202, which will not be described herein.
[0043] In some embodiments of the present application, the support rod 203 is arranged in parallel with the guide roller 101. The parallel arrangement of the support rod 203 and the guide roller 101 ensures the stability and accuracy of the film 4 during movement, reduces the deviation or jamming phenomenon of the film 4 due to unstable path, and improves the winding quality. Specifically, the support rod 203 is made of stainless steel, and one end of the support rod 203 is provided with at least one mounting hole. In use, the support rod 203 can be mounted on the support plate 1 by screws or other fasteners.
