Description

Technical Field

[0001] The utility model relates to the technical field of exposure machines, and specifically relates to a lens switching device for an exposure machine. Background Technique

[0002] An exposure machine is an important piece of machinery. Its main function is to emit ultraviolet light with a UVA wavelength by turning on the light, and transfer the image information on the film or other transparent body to the surface coated with photosensitive substances.

[0003] As the usage time increases, the performance of the lens may be reduced due to the influence of attachments such as dust and stains. These attachments will hinder the transmission and focusing effect of ultraviolet light, resulting in a decline in the exposure effect. At this time, even if there are no obvious signs of damage to the lens, it needs to be replaced to ensure the normal operation of the equipment.

[0004] Therefore, based on the above search and combined with the existing ones, when replacing the lens of the existing exposure machine, due to the position of the lens deep inside the equipment, specific tools or skills are required to complete the disassembly and installation. However, since the lens is a precision component and is easily scratched and collided, during the disassembly and installation process, if not carefully operated, the lens may be damaged and cannot be used, resulting in waste of the lens. Content of the Utility Model

[0005] The purpose of the utility model is to provide a lens switching device for an exposure machine to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A lens switching device for an exposure machine includes a box body. Inside the box body, there is a rubber clamping block rotatably connected for clamping the lens. Inside the box body, there is a belt rotatably connected for driving the rubber clamping block to rotate. At the top of the box body, there is a driving component fixedly installed for driving the belt to rotate. On the outer wall of the box body, there is a clamping structure rotatably installed for clamping and fixing the lens. Inside the box body, there is an arc-shaped push plate rotatably connected for pushing the lens to flip, and the lens is pushed into the clamping structure by the arc-shaped push plate.

[0008] As a further scheme of the utility model, the driving component includes a gear. The bottom of the gear is rotatably connected to the inner cavity of the box body. The bottom of the gear is fixedly connected with a driving shaft for driving the belt to rotate. One end of the gear is meshed with a tooth rail for driving the gear to rotate. The tooth rail is rotatably connected through a bearing with a hydraulic rod for pushing the tooth rail to move.

[0009] As a further solution of the utility model, an annular groove for limiting the tooth rail is formed inside the box body. A plug rod that moves along with the tooth rail is slidably connected to the top of the annular groove, and the top of the plug rod is fixedly connected to the inner cavity of the tooth rail.
