There are iron blocks corresponding to the first electromagnet and the second electromagnet, and the present invention uses a small amount of LED light sources to achieve high exposure quality and low energy consumption.

Description

technical field [0001] The invention belongs to the technical field of exposure devices, and in particular relates to an LED light source exposure device. Background technique [0002] The exposure imaging process is to use pressure (including atmospheric pressure and mechanical pressure) to make the original plate (carrying the graphic medium that needs to be transferred) and the photosensitive plate tightly attached, so that the image on the original plate can be accurately exposed to the photosensitive plate through photochemical reaction. In terms of technology, this device is widely used in various fields such as printing plate making, circuit boards in the electronics industry, and flat panel display manufacturing. At present, traditional exposure devices mainly use mercury lamps, iodine gallium lamps, etc. as light sources. In general, the light source and the photosensitive plate are generally set at a certain distance, and the optical fiber is irradiated on the phot...

Problems solved by technology

[0002] The exposure imaging process is to use pressure (including atmospheric pressure and mechanical pressure) to make the original plate (carrying the graphic medium that needs to be transferred) and the photosensitive plate tightly attached, so that the image on the original plate can be accurately exposed to the photosensitive plate through photochemical reaction. In terms of technology, this device is widely used in various fields such as printing plate making, circuit boards in the electronics industry, and flat panel display manufacturing. At present, traditional exposure devices mainly use mercury lamps, iodine gallium lamps, etc. as light sources. In general, the light source and the photosensitive plate are generally set at a certain distance, and the optical fiber is irradiated on the photosensitive plate using a reflector. Such an exposure device has a large volume and high energy consumption of the light source. In recent years, exposure devices using LED light sources have also appeared. Using a large number of LED arrays as light sources, it is difficult for this exposure device to achieve high uniformity of light, and it is also too expensive to manufacture a large exposure device
