Technical Field
[0001] The utility model relates to the technical field of alignment devices for circuit board exposure machines, and particularly relates to an alignment device for a circuit board exposure machine. Background Art
[0002] In the manufacturing process of printed circuit boards, one of the most critical processes for an exposure machine is to transfer a negative image onto a copper foil substrate. First, a photosensitive material is coated on the substrate. Then, the photosensitive material coated on the substrate is irradiated by light to change its solubility. The resin in the non-photosensitive part does not polymerize and dissolves under the action of a developer, and the resin in the photosensitive part remains on the substrate to form an image. This technological process is exposure, which is the process completed by the exposure machine in the production of printed circuit boards.
[0003] At present, most alignment devices for printed circuit board exposure machines on the market are inconvenient to use. Not only can the circuit board not be limited and fixed during use, but the circuit board may move during processing, affecting the exposure effect. Moreover, it cannot be adjusted and positioned, which may cause exposure errors, increase production costs, and increase the burden on workers.
