[0002] During the operation of magnetron sputtering equipment, a large amount of sputtering residue accumulates inside the chamber, affecting equipment performance and coating quality. Currently, cleaning the coating chamber mainly involves manual wiping or disassembly, but these methods have several problems. Firstly, during cleaning, it's difficult to avoid accidental collisions and damage to delicate components inside the chamber, affecting normal equipment operation. Secondly, disassembling and reassembling the equipment is time-consuming and labor-intensive, increasing the risk of damage during restoration. Overall, these factors negatively impact equipment operation and coating quality. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0016] This utility model provides, for example Figure 1-3The coating chamber shown includes a coating chamber 1 and two side walls 2 and 3 of the coating chamber 1. A movable baffle 8 is provided in the inner cavity of the coating chamber 1. A first driving device for driving the baffle 8 to move is provided at the upper end of the baffle 8. A first guiding device for driving the baffle 8 to move is provided at the lower end of the baffle 8. A movable substrate 11 is provided in the inner cavity of the coating chamber 1. The cross-sectional dimension of the substrate 11 is smaller than that of the baffle 8. A second driving device is provided at the upper end of the substrate 11. A second guiding device is provided at the lower end of the substrate 11. A coating device is provided on one side of the side wall 2.
[0017] Before the substrate 11 enters the coating chamber to begin coating, the coating apparatus has already started sputtering material into the coating chamber 1 environment. After a period of pre-sputtering, the sputtering environment inside the chamber meets the coating requirements. The substrate 11 then enters the chamber at a set speed under the action of the second transport device to begin coating. At the end of coating, the substrate 11 leaves the chamber at a set speed under the action of the second transport device. Before the substrate 11 completely leaves the chamber, the target 13 continues to work until the substrate 11 completely leaves the coating chamber. Before the substrate 11 fully enters and before it completely leaves, the material sputtered by the target 13 is caught by the baffle plate 8 to prevent sputtering onto the sidewall 3. After a period of time, depending on the production intensity and cycle, the baffle plate 8 is transported out of the chamber by the first transport device for cleaning or replacement. After cleaning, it is then transported back into the chamber by the first transport device. This maximizes the protection of the sidewall 3, keeping it clean and ensuring the quality of the coating. This also makes equipment maintenance easier and avoids equipment damage caused by directly cleaning the side wall 23.
[0018] like Figure 1 As shown, both the first drive and the second drive devices include a magnetic guide rail 9 fixedly connected to the upper wall of the coating chamber 1. The magnetic guide rail 9 has magnetic poles inside, and the top of the shielding plate 8 and the substrate 11 are both provided with electromagnets that match the magnetic poles of the magnetic guide rail 9.
[0019] like Figure 1 As shown, the coating apparatus includes a mounting port 12 on one side of the sidewall 2, and a coating machine is fixedly connected to the mounting port 12. The target material 13 is located inside the sidewall 2.
[0020] like Figure 1 The first guiding device includes a rotating rod 4 rotatably connected to the side wall 2 3, and a roller 5 is rotatably connected to one end of the rotating rod 4.
[0021] like Figure 1 As shown, the second guiding device includes a rotating rod 10 rotatably connected to the side wall 2. One end of the rotating rod 10 is rotatably connected to a roller 7. The length of the rotating rod 10 is adapted to the spray range of the coating machine.
[0022] like Figure 2 As shown, the top of the shielding plate 8 is provided with a hoisting device 6 for guiding the shielding plate 8, and the bottom of the shielding plate 8 is provided with a magnetic guide rail 2 14 for driving the shielding plate 8. The magnetic guide rail 2 14 is provided with magnetic poles inside, and the bottom of the shielding plate 8 is provided with an electromagnet that matches the magnetic poles. The hoisting device 6 can be a steel wire rope fixedly connected to the inner wall of the coating chamber 1. A hook is slidably connected to the steel wire rope, and the hook is hooked to the shielding plate 8. Through the cooperation of the magnetic guide rail 2 14 and the hoisting device 6, the distance between the shielding plate 8 and the upper and lower inner walls of the coating chamber 1 can be reduced, and the sputtering residue can be shielded to a greater extent.
[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
