[0031] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0032] This embodiment provides an anti-falling device for preventing the suspension component 4 from falling onto the vacuum coating component 5 .

[0033] like Figures 1 to 3As shown, the anti-fall device includes a support assembly and a stop assembly. The support assemblies are distributed in the horizontal direction, and the stop assembly is arranged on the support assembly so that the stop assembly has a certain height. The stop assembly is located between the suspension assembly 4 and the vacuum coating assembly 5. The stop assembly is arranged on the falling path of the suspension assembly 4. Therefore, if the suspension assembly 4 accidentally falls, the stop assembly with a certain height can pre-empt the suspension assembly 4 to prevent the suspension assembly 4 from falling on the vacuum coating assembly 5 and causing damage to the vacuum coating assembly 5 or even the staff. At the same time, the stop assembly can effectively block the impact force from being transmitted to the outside, preventing the suspension assembly 4 and the workpiece on the suspension assembly 4 from bursting and splashing due to strong impact, which may cause secondary damage to the vacuum coating assembly 5 and the staff.

[0034] Specifically, the support assembly includes a support column 1, and a plurality of support columns 1 are provided. The plurality of support columns 1 are arranged in a circumferential manner, so that the plurality of support columns 1 can support different positions of the stop assembly, thereby improving the supporting capacity and allowing the stop assembly to have a certain height while maintaining stability. Among them, the stop assembly includes an annular support member 2, and the annular support member 2 is provided on the plurality of support columns 1, so that the annular support member 2 has an inner ring channel, so that the gaseous film material molecules emitted by the evaporation source 51 of the vacuum coating assembly 5 can rise and pass through the inner ring channel. Optionally, the anti-fall device also includes an anti-fouling guard plate, which is provided outside the support column 1 and the annular support member 2 to protect the support column 1 and the annular support member 2 from pollution, thereby reducing the maintenance difficulty and maintenance cost of the support column 1 and the annular support member 2.

[0035] The annular support member 2 is located between the suspension assembly 4 and the vacuum coating assembly 5, and the annular support member 2 is arranged on the path of the suspension assembly 4 falling. The buffer member 3 is arranged on the annular support member 2. Therefore, if the suspension assembly 4 accidentally falls, the annular support member 2 having a certain height can pre-accept the suspension assembly 4 to prevent the suspension assembly 4 from falling on the vacuum coating assembly 5 and causing damage to the vacuum coating assembly 5 or even the staff. At the same time, the anti-fall device includes a buffer member 3. The buffer member 3 is arranged on the annular support member 2. The buffer member 3 on the annular support member 2 can cushion the suspension assembly 4, effectively blocking the impact force from being transmitted to the outside, preventing the suspension assembly 4 and the workpiece on the suspension assembly 4 from bursting and splashing due to strong impact, causing secondary damage to the vacuum coating assembly 5 and the staff. The buffer member 3 can also protect the suspension assembly 4 itself, preventing large deformation of the mechanical parts, thereby reducing the recovery cost of the suspension assembly 4. Optionally, the suspension assembly 4 is a suspension rotary mechanism. Further optionally, the buffer member 3 is made of Teflon material. Of course, the buffer member 3 may also be made of other materials, which is not specifically limited in this embodiment.

[0036] like Figure 1 and Figure 2As shown, the annular support member 2 includes a plurality of arc-shaped members 21, which are connected end to end to form the annular support member 2. The arc-shaped members 21 are arranged on the support column 1, and the buffer member 3 is arranged on the arc-shaped member 21. By dividing the annular support member 2 into multiple arc-shaped members 21, it is convenient for workers to remove part of the support column 1 and part of the arc-shaped member 21 according to actual needs, thereby avoiding the vacuum coating assembly 5 and preventing part of the support column 1 and part of the arc-shaped member 21 from interfering with the position setting of the vacuum coating assembly 5. Optionally, multiple buffer members 3 are provided, and multiple buffer members 3 are arranged on the arc-shaped member 21 along an arc trajectory, so that workers can adjust the number of buffer members 3 to meet actual needs. Specifically, when the position of the evaporation source 51 in the vacuum coating assembly 5 is adjusted, the evaporation path of the gaseous film material molecules emitted by the evaporation source 51 will be blocked by part of the supporting column 1 and part of the arc-shaped member 21. At this time, the part of the supporting column 1 and part of the arc-shaped member 21 can be removed. While ensuring the film-forming effect, the anti-fall device can still play a protective role.

[0037] Among them, the arc-shaped part 21 has a positioning groove 211 extending along the arc-shaped trajectory, and the buffer part 3 is embedded in the positioning groove 211, so that the buffer part 3 can be positioned by the positioning groove 211 to facilitate the installation of the buffer part 3, and the positioning groove 211 can stop the buffer part 3 to prevent the suspension component 4 from falling onto the buffer part 3, and the buffer part 3 will move along the radial direction of the annular support part 2 to cause the suspension component 4 to fall off. At the same time, by setting the positioning groove 211, the weight of the arc-shaped part 21 can also be reduced, thereby facilitating the installation and disassembly and maintenance of the arc-shaped part 21.

[0038] Furthermore, the buffer 3 includes a mounting portion 31 and a stop portion 32 that are vertically connected to each other. The mounting portion 31 is provided on the annular support 2, and the stop portion 32 is provided on a side close to the outer end of the annular support 2. Thus, after the suspension assembly 4 falls onto the buffer 3, the stop portion 32 can stop the suspension assembly 4, thereby preventing the suspension assembly 4 from sliding off the buffer 3 and falling, thereby further improving the anti-fall effect of the anti-fall device on the suspension assembly 4. Specifically, the mounting portion 31 is provided with a mounting hole 311, through which the connector can pass to connect to the annular support 2, thereby achieving fixed installation of the buffer 3 on the annular support 2, improving the stability of the buffer 3 on the annular support 2, and preventing the buffer 3 from falling together with the suspension assembly 4 after being subjected to a large impact force.

[0039] Furthermore, the support column 1 includes a support portion 11 and a connecting portion 12 that are interconnected. The connecting portion 12 has a U-shaped groove, and the annular support member 2 is embedded in the U-shaped groove. This improves the stability of the connection between the support column 1 and the annular support member 2, further improving the overall impact resistance of the fall protection device. Optionally, the support portion 11 also has a weight reduction hole 111. By providing the weight reduction hole 111, the weight of the support column 1 can be reduced, thereby facilitating the installation, removal and maintenance of the support column 1.

[0040] This embodiment also provides a coating chamber, including the anti-falling device as described above, such as Figure 3 As shown, the coating chamber has a coating cavity 6, and the coating chamber also includes a suspension component 4 and a vacuum coating component 5. The suspension component 4 and the vacuum coating component 5 are respectively located at the upper and lower ends of the coating cavity 6, and the annular support 2 of the anti-falling device is located between the suspension component 4 and the vacuum coating component 5, so that the anti-falling device can cushion the falling suspension component 4, effectively blocking the impact force from being transmitted to the outside, and preventing the suspension component 4 and the workpiece on the suspension component 4 from causing damage to the vacuum coating component 5 and the staff.

[0041] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
