Description

Technical Field

[0001] The utility model relates to the technical field of vacuum coating machines, in particular to a locking mechanism of a vacuum coating device. Background Art

[0002] Vacuum coating machine mainly refers to a type of coating that needs to be carried out under a higher vacuum degree. There are many types, including vacuum resistance heating evaporation, electron gun heating evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition, ion beam sputtering, etc. The main idea is to divide it into two types: evaporation and sputtering.

[0003] For example, the patent announcement number is CN219032350U, a locking structure of a vacuum coating machine, including a fixing frame and a mounting plate respectively fixed to the equipment body of the external vacuum coating machine and the side of the sealing door, one end of the mounting plate extends to the outside of the sealing door and fixes the limit rod. In the utility model, the locking force during locking can be adjusted by the different upward movement distances of the output end of the electric push rod, that is, when the locking structure proposed in this scheme is used for a long time and the parts are worn, the output end of the electric push rod can be moved upward to ensure that the locking effect of the structure on the vacuum coating machine will not decrease, thereby solving the defect that the traditional locking structure decreases the locking effect due to the wear of the parts after long-term use, affecting the vacuum degree in the working chamber of the vacuum coating machine. However, when the above-mentioned locking structure is used, the traction rope will move on the roller surface for a long time. Since the traction rope and the roller will be exposed to the outside for a long time, when they are oxidized or worn, the service life of the traction rope and the roller will be reduced. For this reason, we propose a locking mechanism for a vacuum coating device to solve the above problem. Utility Model Content

[0023] Further, see Figure 2 and Figure 3It can be known that a driving push rod 8 is inserted into the top surface of the liquid storage tank 6, and a sealing block 9 is fixedly connected to the bottom end of the driving push rod 8, and a fixing ring 10 is fixedly connected to the inner wall of the bottom end of the liquid storage tank 6. A groove matching the surface size of the sealing block 9 is opened inside the fixing ring 10. Through the groove opened inside the fixing ring 10, the driving push rod 8 can drive the sealing block 9 to be inserted into the groove, which facilitates the sealing between the guide oil pipe 5 and the liquid storage tank 6.

[0024] Further, see Figure 3 and Figure 4 It can be known that the driving push rod 8 is set to be cylindrical, and a circular hole compatible with the driving push rod 8 is opened on the top surface of the liquid storage tank 6. The driving push rod 8 can move in the circular hole through the circular hole opened on the top surface of the liquid storage tank 6. The top end of the driving push rod 8 is fixedly connected to a limiting plate 11, and the surface diameter of the limiting plate 11 is larger than the surface diameter of the driving push rod 8. The limiting plate 11 can facilitate the limiting of the driving push rod 8.

[0025] Further, see Figure 3 and Figure 4 It can be known that a return spring 12 is welded between the top surface of the liquid storage tank 6 and the bottom surface of the limit plate 11, and the top end of the driving push rod 8 is inserted into the inside of the return spring 12. Through the elastic force of the return spring 12 itself, the limit plate 11 can facilitate the driving push rod 8 to reset.

[0026] Further, see Figure 3 and Figure 4 It can be known that the inner wall of the liquid storage tank 6 is fixedly connected with multiple groups of supporting cylinders 13, and the outer ends of the multiple groups of supporting cylinders 13 are fixedly connected with guide seats 14. The multiple groups of supporting cylinders 13 can facilitate the function of limiting the support guide seats 14.

[0027] Further, see Figure 3 and Figure 4 It can be known that the guide seat 14 is set to be disc-shaped, and a circular hole compatible with the driving push rod 8 is opened inside the guide seat 14.

[0029] Working principle: When the utility model is in use, when the locking mechanism body 1 is in use, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 , lubricating oil can be injected into the liquid storage tank 6 through the oil filling port 7. At this time, pressing the limit plate 11 can make the limit plate 11 drive the driving push rod 8 to slide along the inside of the liquid storage tank 6 and the guide seat 14. When the driving push rod 8 drives the sealing block 9 away from the fixing ring 10, the lubricating oil inside the liquid storage tank 6 enters the guide oil pipe 5 through the fixing ring 10 and drips into the inside of the protective outer frame 4, lubricating the connecting traction rope 2 and the guide roller 3, reducing the wear of the connecting traction rope 2 and the guide roller 3 when in use. At the same time, after the connecting traction rope 2 and the guide roller 3 are lubricated, the limit plate 11 is loosened, and the elastic force of the reset spring 12 itself can make the driving push rod 8 drive the sealing block 9 to reset, so that the sealing block 9 is engaged in the fixing ring 10, which is convenient for separating the liquid storage tank 6 from the guide oil pipe 5, and plays a role in controlling the amount of lubricating oil dripping inside the liquid storage tank 6. At the same time, the amount of lubricating oil inside the liquid storage tank 6 can be conveniently observed through the observation window 15;

[0030] The above is the entire working principle of the utility model.
