UV-LED exposure light source bracket

Abstract

The invention discloses a UV-LED exposure light source bracket. The UV-LED exposure light source bracket comprises a supporting rod and a rotary rod, wherein the top of the supporting rod is fixedly connected with a fixed table board; the lower surface of the fixed table board is fixedly connected with a screw; the outer surface of the screw is separately in threaded connection with an upper nut and a lower nut; a gasket is fixedly connected between the upper nut and the lower nut; the two sides of the gasket are fixedly connected with slide blocks; one side of the supporting rod is fixedly equipped with a slide slot; the slide blocks are in sliding connection with the inner wall of the slide slot; a long branch which is fixedly connected to one side of the supporting rod is arranged on the bottom of the gasket; a light reflecting mirror sleeves the outer surface of the rotary rod; one end of the rotary rod is welded with a handle; and the back surface of the supporting rod is fixedlyconnected with a short branch. According to the UV-LED exposure light source bracket disclosed by the invention, the rotary rod, a handle, a pointer, a protractor, a screw, the upper nut, the lower nut, the gasket, the slide slot and the slide blocks are arranged, so that the problems that the angle of the light reflecting mirror is un-adjustable, collimation degree and uniformity of parallel light and height of an exposure light source are un-adjustable, and light source regulating efficiency is low are solved.

Description

technical field [0001] The invention relates to the technical field of exposure machines, in particular to a UV-LED exposure light source bracket. Background technique [0002] In the printed circuit board industry, the transfer of negative film graphics to the circuit board is completed by using an exposure machine. The exposure machine bracket is the workbench for the circuit board exposure light source. Specifically, a mask is placed on the substrate coated with photoresist. Then use the exposure machine to expose the substrate. Specifically, the exposure machine emits UV ultraviolet light by turning on the exposure light source, and transfers the image information on the mask plate to the surface of the substrate coated with photoresist. Based on the pattern of the mask plate, photolithography The glue will have exposed parts and unexposed parts. Then use the developer to develop the photoresist to remove the exposed part of the photoresist and keep the unexposed part o...

Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the present invention provides a UV-LED exposure light source bracket, which matches the new UV-LED exposure light source, and solves the problem that the angle of the reflector cannot be adjusted, which affects the uniformity of parallel light and the exposure light source. The height cannot be adjusted, and the light source detection efficiency is reduced
