Abstract

The invention belongs to the field of exposure machines and relates to an exposure machine based on a CCD alignment system. The exposure machine comprises an adjusting device and an executing device; the adjusting device is positioned in the executing device; the adjusting device comprises a substrate and an adjusting assembly positioned at the upper part of the substrate; the adjusting assembly comprises a first frame; the upper surfaces of the two sides of the first frame are each provided with two sets of electromagnet devices; the two ends of the bottom of the first frame are each fixedly provided with two sets of electric telescopic rods; and the output ends of the two sets of electric telescopic rods located on the same side are fixedly provided with the same arc-shaped guide block. According to the exposure machine based on the CCD alignment system of the invention, two groups of matrix type laser radiation devices are used for synchronously scanning the two surfaces of the same PCB, and the CCD alignment system is used for uniformly positioning and adjusting the PCB, so that the problems of poor exposure product, low exposure efficiency and need of repeated exposure are solved.

Description

technical field [0001] The invention relates to the field of exposure machines, in particular to an exposure machine based on a CCD alignment system. Background technique [0002] Exposure machines are widely used in electrical technology products, such as the application of right semiconductor wafers, PCB circuit boards, thin-film chip resistors, etc. Exposure machines are mainly used to display electronic circuit graphics on product parts In order to obtain electronic parts products with small volume and multi-layer circuits. [0003] Exposing machines in the prior art usually use ultraviolet light of UVA wavelength by turning on the light to transfer the image information on the film or other transparent body to the surface coated with photosensitive material. This type of exposing machine has the following defects: [0004] 1. It is necessary to use negative film and apply film on the negative film. Due to the existence of film, dirty spots are easy to appear during the...
