Description

Technical Field

[0001] The utility model relates to the technical field of highlight exposure, and more specifically, to a highlight exposure mechanism of an automatic exposure machine. Background Art

[0002] An exposure machine is a device that uses a light to emit UVA wavelength ultraviolet light to transfer image information from film or other transparent objects to a surface coated with a photosensitive material. It is widely used in the fields of semiconductors, microelectronics, biodevices, and nanotechnology. For example, Patent Publication No. CN211786590U discloses a high-brightness exposure mechanism for an automatic exposure machine. The device is mounted in its operating position using a mounting plate at the bottom of the base plate and connected to a power source. The circuit board then drives the LED bulb to emit light, which is then guided by a light guide to prevent light dispersion. The light is then emitted through a transparent cover plate to illuminate the object being exposed. When the transparent cover plate needs to be cleaned, the user simply unscrews the screw and pulls the cover plate upward to disengage the positioning plate from the positioning slot, allowing the cover plate to be pulled out of the top plate. The new cover plate is then inserted into the top plate through the positioning plate and the positioning slot. The screw is then screwed in again to lock the positioning plate, thereby locking the cover plate in place and enabling quick replacement of the cover plate.

[0003] When the above device is working, the shell can be quickly disassembled and assembled through the arrangement of the connecting block, connecting groove, clamping block, clamping groove and spring, so as to facilitate the maintenance or replacement of the LED bulb, effectively improving the maintenance or replacement efficiency of the device components, ensuring the normal use of the device, and being easy to operate, saving time and effort, greatly improving the practicality of the device. However, its structure is relatively complex, and the installation and disassembly of the LED bulb is relatively cumbersome, which causes inconvenience to the installation and maintenance operations of the LED bulb.
