[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the present invention.

[0023] Reference Figure 1 、 Figure 2 and Figure 3 As shown, a cleaning device for vacuum coating machine cavity processing includes a U-shaped frame 1, which includes a top arm 11, a vertical shell 12, and a bottom arm 13. A connecting shaft 111 is fixedly mounted on each of the top arm 11 and the bottom arm 13. The top arm 11 and the bottom arm 13 are fixedly mounted on both ends of the vertical shell 12. A scraper assembly 2 is mounted in the vertical shell 12, and an elastic bracket 3 for locking the scraper assembly 2 is mounted on each of the top arm 11 and the bottom arm 13. The head of the elastic bracket 3 passes through the vertical shell 12 and is inserted into the scraper assembly 2. The U-shaped frame 1 is structurally configured to ensure that the top arm 11, vertical housing 12, and bottom arm 13 form a U-shaped structure. Connecting shafts 111 are fixedly mounted on the top and bottom arms 11, 13. This allows the U-shaped frame 1 to be rotatably mounted inside the vacuum coating machine via the connecting shafts 111 at both ends during use, ensuring that it can be driven by a motor to achieve rotational operation. A scraper assembly 2 is installed in the vertical housing 12 to ensure that the U-shaped frame 1 rotates and drives the scraper assembly 2 to rotate synchronously for cleaning. The elastic bracket 3 is positioned to ensure that the scraper assembly 2 is stably pressed against the inner wall of the vacuum coating machine chamber, ensuring a better cleaning effect. A longitudinal slot 121 is provided in the middle of the vertical housing 12 for mounting the scraper assembly 2, and a positioning slot 122 is provided on one side of the vertical housing 12 to cooperate with the elastic bracket 3. The longitudinal slot 121 ensures that the scraper assembly 2 is stably mounted, while the positioning slot 122 ensures that the elastic bracket 3 is better able to pass through and lock the scraper assembly 2.

[0024] Reference Figure 3As shown, the scraper assembly 2 includes an I-shaped vertical frame 21 and an angled scraper 22. The angled scraper 22 is evenly arranged on the outer surface of the I-shaped vertical frame 21 and is fixedly connected to the I-shaped vertical frame 21. The structural configuration of the scraper assembly 2 ensures that the angled scraper 22 is fixedly mounted on the I-shaped vertical frame 21. When used, the angled scraper 22 can be attached to the internal cavity of the vacuum coating machine. The I-shaped vertical frame 21 is provided with a locking socket 211 corresponding to the elastic bracket 3. The provision of the locking socket 211 ensures that the elastic bracket 3 is stably inserted and locked.

[0025] Reference Figure 4 and Figure 5 As shown, the elastic bracket 3 includes a slide rod 31 and a housing 32. The housing 32 is mounted on the slide rod 31, and a support spring 321 connected to the slide rod 31 is fixedly installed in the housing 32. The structural design of the elastic bracket 3 ensures that the slide rod 31 and the housing 32 are slidingly engaged. The support spring 321 also ensures that the housing 32 is pushed into the locking hole 211 for locking. A positioning seat 311 is fixedly mounted on the outer end of the slide rod 31, and a paddle 322 is fixedly mounted on the lower end of the housing 32. The positioning seat 311 also ensures stable installation on the U-shaped frame 1.

[0026] Working principle: When cleaning is required, the scraper assembly is driven to rotate synchronously by rotating the U-shaped frame, so that the scraper assembly can stably clean the inside of the vacuum coating machine cavity under the support of the elastic bracket.
