Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum coating equipment technology, and in particular to a multi-chamber vacuum magnetron coating machine. Background Technology
[0002] Existing vacuum magnetron coating equipment has a limited number of vacuum chambers, typically single or double chambers; and can only be used for vacuuming individually, not for coating workpieces simultaneously.
[0003] In addition, most existing vacuum magnetron sputtering coating equipment uses diffusion pumps to evacuate the vacuum chamber, which causes large fluctuations in vacuum level during the evacuation process, resulting in unstable coating and inconsistent quality of finished coating products with a high scrap rate.
[0004] Furthermore, existing vacuum magnetron coating equipment typically uses hinged or sliding doors for partitions, which not only results in poor structural sealing performance but also places high demands on the footprint and space required for the assembly of the entire equipment. Utility Model Content
[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a multi-chamber vacuum magnetron coating machine, which is a multi-vacuum chamber combination structure. When there are two or more magnetron coating chambers, the workpiece can be coated individually or simultaneously, effectively improving production efficiency. Moreover, the vacuum chambers are evacuated by using multiple molecular pumps, resulting in small vacuum fluctuations, which can effectively improve the stability of vacuum coating.

[0037] The following is for reference. Figures 1-4 A multi-chamber vacuum magnetron coating machine is described in detail with reference to a specific embodiment. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.
[0038] like Figure 1As shown, a multi-chamber vacuum magnetron coating machine includes several vacuum chambers 100 connected in sequence, and at least one vacuum chamber 100 is used for magnetron coating of workpieces. Isolation devices 110 are connected to the inlet end, outlet end and adjacent vacuum chambers 100 of the vacuum chamber 100. Isolation devices 110 are used to open or close the inlet and outlet channels of workpieces. Several vacuum pumping components 120 are provided on each vacuum chamber 100. The vacuum pumping components 120 are composed of several molecular pumps 130. The molecular pumps 130 are used to evacuate the vacuum chamber 100.
[0039] This utility model includes several vacuum chambers 100 connected in sequence, and at least one of the vacuum chambers 100 is configured as a coating chamber for magnetron coating of workpieces. The structure of multiple vacuum chambers 100 combined allows for individual or simultaneous coating of workpieces, effectively improving production efficiency. Isolation devices 110 are connected to the inlet and outlet ends of the vacuum chambers 100 and between adjacent vacuum chambers 100. Isolation devices 110 can open or close the entry and exit channels of workpieces, thereby resulting in good structural sealing performance and small overall space occupation. Several vacuum pumping components 120 are provided on each vacuum chamber 100, and the vacuum pumping components 120 are composed of several molecular pumps 130, thereby allowing vacuum pumping of the vacuum chambers 100, resulting in small vacuum fluctuations and effectively improving the stability of vacuum coating.
[0040] In the first specific embodiment of this utility model, specific reference is made. Figure 1 and Figure 2 The vacuum chamber 100 is provided with three chambers, namely the front low vacuum chamber 140, the magnetron coating chamber 150, and the rear low vacuum chamber 160100.
[0041] The vacuum chamber 100 is configured with three chambers, namely the front low vacuum chamber 140, the magnetron coating chamber 150, and the rear low vacuum chamber 160. The workpiece is magnetron coated in the magnetron coating chamber 150. The whole machine consists of three vacuum chambers 100, which makes the overall structure occupy less space and facilitates the installation and placement of the whole machine.
[0042] In the second specific embodiment of this utility model, referring to Figure 3 The vacuum chamber 100 is provided with four chambers, which are, in order, the first vacuum chamber 170, the first coating chamber 180, the second coating chamber 190, and the second vacuum chamber 200.
[0043] When four vacuum chambers 100 are set, they are, in sequence, the first vacuum chamber 170, the first coating chamber 180, the second coating chamber 190, and the second vacuum chamber 200. Both the first coating chamber 180 and the second coating chamber 190 can perform magnetron coating on the workpiece. Thus, during the production process, the workpiece can be coated simultaneously, effectively improving the efficiency of coating the workpiece.
[0044] Specifically, vacuum pumping components 120 are provided on both sides of the vacuum chamber 100.
[0045] Vacuum pumping components 120 are provided on both sides of the vacuum chamber 100, thereby making the vacuum pumping components 120 reasonably positioned, improving the vacuum pumping efficiency while ensuring the vacuum pumping effect.
[0046] In some specific embodiments of this utility model, a plurality of molecular pumps 130 are provided on the top of the magnetron coating cavity 150.

[0048] Furthermore, the molecular pumps 130 are respectively located at the corners of the top of the magnetron coating cavity 150.
[0049] By placing the molecular pump 130 at the corner of the top of the magnetron coating cavity 150, the molecular pump 130 is reasonably positioned and fully distributed, which can meet the vacuuming requirements of the magnetron coating cavity 150 and ensure the vacuuming effect of the magnetron coating cavity 150.
[0050] Preferably, the molecular pump 130 is a high-speed molecular pump 130.
[0051] The high-speed molecular pump 130 is characterized by its small size and low energy consumption. Compared with the diffusion pump, the high-speed molecular pump 130 causes less contamination to the vacuum chamber 100, thereby making the vacuuming process energy-saving and environmentally friendly.

[0053] It should be noted that the vacuum slide valve 210 includes a valve body 220, a valve 230, and a drive mechanism. The valve body 220 has a workpiece passage 240. The valve 230 is located at the passage 240 and can isolate and seal adjacent vacuum chambers 100. The drive mechanism includes drive cylinders 250 respectively located on both sides of the passage 240.

[0054] The isolation device 110 is a vacuum slide valve 210, which opens or closes the workpiece entry and exit channel by means of pneumatic means, thereby making the vacuum chamber 100 have good sealing performance, occupy little space, and be easy to install and use.
[0055] Preferably, it also includes a frame 260 for supporting the vacuum chamber 100.
[0056] By setting up the frame 260, the vacuum chamber 100 can be installed and supported, which can make the vacuum chamber 100 installed stably and ensure the stability and smoothness of the vacuum magnetron coating process.
