DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0041] An optical lens vacuum coating machine, such as Figure 1-3 As shown, it includes a base 1, a storage table 2, an outer shell 4, a coating component, a cooling component and a filtering component. The top of the base 1 is connected to the storage table 2, the top of the storage table 2 is rotatably connected to the outer shell 4, a coating component is provided between the base 1 and the outer shell 4, a cooling component is provided on the upper part of the oil tank 17, and a filtering component is provided on the lower part of the oil tank 17.

[0042] like Figure 1-3 As shown, the coating assembly also includes a stepper motor 6, a rotating shaft 7, an engine 9, a heating tube 10, a vacuum coating chamber 12 and an oil tank 17. A stepper motor 6 is installed in the middle of the base 1, and the output shaft of the stepper motor 6 is connected to the rotating shaft 7. The top of the rotating shaft 7 is connected to the oil tank 17, and the bottom of the oil tank 17 is connected to the engine 9. A plurality of heating tubes 10 are connected to the outer side of the upper part of the engine 9, and the heating tubes 10 pass through the lower part of the outer shell 4 and are all connected to the vacuum coating chamber 12.

[0043] When people use this device to coat the optical lens, start the stepper motor 6. The stepper motor 6 can perform angle feeding according to the time and angle settings. When the storage table 2 is rotated to be separated from the vacuum coating chamber 12, turn off the stepper motor 6, put the optical lens into the storage table 2, and start the stepper motor 6 again. The stepper motor 6 rotates, driving the rotating shaft 7 to rotate, and at the same time drives the oil tank 17 and the outer shell 4 to rotate, thereby driving the heating tube 10 and the vacuum coating chamber 12 to rotate. Each rotation is used to coat the optical lens once, thereby achieving multiple coatings of the optical lens. Example

[0044] On the basis of Example 1, Figure 1 and Figure 4 As shown, the cooling component also includes a cooling bin 5, a water bin 13, a water pump 14, a water pipe 15 and a nozzle 16. The cooling bin 5 is rotatably connected to the top of the oil tank 17. The upper part of the cooling bin 5 is connected to the water bin 13. The left and right sides of the water bin 13 are connected to the water pump 14. The upper part of the water bin 13 is connected to multiple water pipes 15. The water pumps 14 are all connected to the water pipes 15. The water pipes 15 are located inside the upper side of the cooling bin 5. The lower part of the water pipes 15 is connected to the nozzles 16. The nozzles 16 are located above the vacuum coating bin 12.

[0045] It also includes a water storage platform 3, and the outer side of the bottom of the base 1 is connected to the water storage platform 3.

[0046] During coating, since heat is generated, the vacuum coating chamber 12 needs to be cooled, and the water pump 14 is started. The water pump 14 draws water from the water chamber 13 to the water pipe 15, and then sprays it out through the nozzle 16. The nozzle 16 sprays water onto the outer shell 4 below to cool the vacuum coating chamber 12. The water storage table 3 on the outside of the bottom of the base 1 will collect the used water after cooling.

[0047] like Figure 3 As shown, the filter assembly also includes a scraper ring 8 and a filter screen 11 . The filter screen 11 is connected to the lower part of the oil tank 17 . The scraper ring 8 is slidably connected to the lower part of the oil tank 17 . The scraper ring 8 is located above the filter screen 11 .

[0048] After the fuel tank 17 has been used for a period of time, some oil residue may be generated inside. The scraper ring 8 is manually pulled to clean the oil residue on the surface of the filter screen 11, so that the inside of the fuel tank 17 remains clean and the service life of the engine 9 is extended.

[0049] The observation window on the housing 4 is made of transparent material, so the coating condition inside can be observed.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
