Description

Technical Field

[0001] The utility model relates to the technical field of lens coating, in particular to a coating device for processing projection lamp lenses. Background Technique

[0002] The main function of a projection lamp is to convert electrical energy into light energy to generate images. They project light rays to present vivid images and videos, featuring high brightness output, color reproduction, high definition, adjustable focal length and projection size, multimedia connection interfaces, and long durability.

[0003] The lens in front of the projector bulb is usually called a "lens" and is made of a special optical glass. Its function is to concentrate the light rays emitted by the bulb onto a point to produce a high-brightness light beam, thus ensuring the clarity and brightness of the projected image. Before being installed in a projector for use, it must be subjected to coating processing. Coated lenses utilize new technologies of optical thin films and vacuum to deposit a certain thickness of single or multiple optical thin films, enabling the lenses to obtain some new excellent properties that they originally did not possess, improving the ability of the lenses to reflect light, playing a role in enhancing or reducing light transmission, and significantly increasing the light transmittance of the lenses.

[0004] Chinese patent document CN212834010U discloses a coating device for processing optical lenses, including a substrate. On both sides of the upper surface of the substrate, side plates are fixedly installed. On the top of the side plates, a top plate is fixedly installed. The output end of the electric push rod is fixedly connected to a first support plate. On both sides of the bottom surface of the first support plate, support rods are fixedly installed. On one side of each support rod, a guide block is fixedly installed. The bottom surface of the support rod is fixedly connected to a second support plate. On the upper surface of the second support plate, a motor is fixedly installed. The output end of the motor is fixedly connected to a rotating shaft. The bottom end of the rotating shaft penetrates through the second support plate and is fixedly connected to a pressing block. The bottom end of the spring is fixedly connected to an annular cutter. By setting the electric push rod to drive the pressing block fixedly connected to the second support plate to press down on the coated optical lens, and setting the motor to drive the pressing block to rotate, the coating effect is improved. The second support plate drives the annular cutter to press down to perform circumferential cutting on the coating to remove the excess coating film, improving the working efficiency of coating the optical lens.

[0005] In the implementation process of the above patent document, the lens can be clamped and the excess coating film can be removed by circumferential cutting. However, it cannot dry the coated lens, resulting in a long waiting time until the coating liquid is completely dry after spraying the coating liquid, greatly reducing the coating processing efficiency of the projector lens.
