Description

Technical Field

[0001] This utility model relates to the field of multi-layer lens technology, and specifically to a multi-layer lens coating device. Background Technology

[0002] The term "multi-coating" in multi-layer lenses refers to a lens surface covered with two or more coating layers. This coating technology optimizes various optical properties by superimposing multiple functional layers at different levels. The coating is achieved by depositing one or more thin films on the lens surface through physical or chemical methods to improve the lens's light transmission, reduce reflection, and enhance scratch resistance, among other properties.

[0003] In the prior art, a Chinese patent document with publication number CN220520615U and publication date of February 23, 2024, was proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a lens coating device, including a coating device body and a drying component disposed on the surface of the coating device body; by installing the drying component on the coating device body, the heating rod inside the fixed tube is heated by opening the heating module on one side of the fixed tube during use, and connected to the ventilation pipe by a fan.

[0004] To address the issue of drying lens coatings, existing technologies employ a fan to heat air through a ventilation duct, facilitating rapid drying of the coating solution on the lens surface and improving drying efficiency. However, this drying component is located on the right side of the coating unit, and its hot air outlet also blows air inward from the right side of the unit. This results in uneven heating of the lens on the left side of the coating unit, reducing drying efficiency. Furthermore, the filter at the air inlet can only be cleaned when the unit is not in operation, causing inconvenience. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layer lens coating device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

The exhaust hood facilitates the discharge of heated gas into the conveying pipe.

[0011] A further improvement of this utility model is that a conical filter screen is fixedly installed around the top of the air duct, and a fine particle filter screen is fixedly installed at the top of the inner wall of the air duct. The conical filter screen filters the gas drawn into the air duct, and the fine particle filter screen further filters it.

[0012] A further improvement of this utility model is that a bidirectional motor is fixedly installed at the top and bottom of the air duct, and the top output end of the bidirectional motor extends to the top of the conical filter screen and is fixedly sleeved with a cleaning brush. The cleaning brush rotates and fits against the outer surface of the conical filter screen, and the cleaning brush can clean the impurities adhering to the outer surface of the conical filter screen.

[0013] A further improvement of this utility model is that a drive rod is fixedly installed on the bottom output end of the bidirectional motor, and a fan blade is fixedly sleeved on the other end of the drive rod.

[0025] Example 1

[0026] like Figure 1-5As shown, this utility model provides a multi-layer lens coating device, including a coating device 1. The coating device 1 includes a coating box 2, a drying cylinder 3 fixedly installed on the top of the coating box 2, and a spray hood 4 provided at the top of the interior of the coating box 22. Connecting vertical rods 41 are fixedly installed on all four sides of the top of the spray hood 4, and the other end of the connecting vertical rods 41 is fixedly installed at the top and bottom of the coating box 2.

[0027] A support bracket 31 is fixedly installed at the bottom of the inside of the drying cylinder 3. An air guide pipe 34 is fixedly installed at the output end of the drying cylinder 3. The other end of the air guide pipe 34 passes through the top of the coating box 2 and extends into the top of the spray hood 4. A heater 32 is fixedly installed at the top of the drying cylinder 3. A heating pipe 33 is fixedly installed at the connection end of the heater 32. The other end of the heating pipe 33 is fixedly installed at the top of the support bracket 31.

[0028] Furthermore, the bottom output end of the bidirectional motor 310 drives the drive rod 312 to cause the fan blades 313 to rotate and generate suction, drawing outside air into the interior of the air duct 37. The air is then filtered by the conical filter screen 38 and further filtered by the fine particle filter screen 39. The air enters the interior of the air duct 37 and is introduced into the interior of the delivery pipe 316 through the exhaust port 315. The delivery pipe 316 is wrapped with a heating pipe 33, which heats the air inside the delivery pipe 316. This hot air then flows into the interior of the coating box 2, facilitating the comprehensive drying of the lens.

[0029] Example 2

[0030] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, an exhaust hood 35 is fixedly sleeved on the outer surface of the bottom end of the heating pipe 33; a support plate 36 is fixedly installed on the top of the drying cylinder 3 above the heater 32; a wind duct 37 is threadedly sleeved on the top of the support plate 36; a conical filter screen 38 is fixedly installed around the top of the wind duct 37; a fine particle filter screen 39 is fixedly installed at the top of the inner wall of the wind duct 37; and a bidirectional motor 310 is fixedly installed at the top and bottom of the wind duct 37. The top output end of 10 extends to the top of the conical filter screen 38 and is fixedly fitted with a cleaning brush 311. The cleaning brush 311 rotates and fits against the outer surface of the conical filter screen 38. A drive rod 312 is fixedly installed on the bottom output end of the bidirectional motor 310. A fan blade 313 is fixedly fitted on the other end of the drive rod 312. Exhaust ports 315 are opened on both sides of the bottom end of the support plate 36. A conveying pipe 316 is fixedly installed on the output end of the exhaust port 315. The other end of the conveying pipe 316 is fixedly installed inside the top of the exhaust hood 35.

[0031] Furthermore, it is filtered by a conical filter screen 38 and further filtered by a fine particle filter screen 39. When the bidirectional motor 310 starts, its top output end drives the cleaning brush 311 to rotate. When the cleaning brush 311 rotates, it rotates on the outer surface of the conical filter screen 38 to clean the impurities adhering to its outer surface.

[0032] The working principle of this multi-layer lens coating device will be explained in detail below.

[0033] like Figure 1-5 As shown, during use, the heater 32 and heating pipe 33 are activated, and the bottom output end of the bidirectional motor 310 drives the drive rod 312 to rotate the fan blades 313, generating suction to draw outside air into the interior of the air duct 37. The air is then filtered by the conical filter screen 38 and further filtered by the fine particle filter screen 39. The air enters the interior of the air duct 37 and is introduced into the interior of the delivery pipe 316 through the exhaust port 315. The delivery pipe 316 is wrapped around the heating pipe 33, which heats the air inside the delivery pipe 316. The hot air gradually flows into the interior of the exhaust hood 35 and into the guide pipe 34. It then enters the interior of the spray hood 4 through the guide pipe 34 and is blown downwards by the spray hood 4 to thoroughly dry the coated lens. When the bidirectional motor 310 is started, its top output end drives the cleaning brush 311 to rotate. As the cleaning brush 311 rotates, it rotates on the outer surface of the conical filter screen 38 to clean the impurities adhering to its outer surface.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
