[0002] In printed circuit board manufacturing process, one of the most critical processes is to transfer the negative image to the substrate. First, a layer of photosensitive material is coated on the substrate, and then the photosensitive material coated on the substrate is subjected to light radiation, so that its solubility changes. The resin of the non-photosensitive part is not polymerized and is dissolved under the action of the developing solution. The photosensitive material of the photosensitive part undergoes polymerization reaction and solidifies on the substrate to form an image. This process is exposure, which is the process completed by the exposure machine in printed circuit board production.

To achieve precise alignment, multiple recognition modules are often installed in the corners of the equipment for multi-angle comparison and alignment. The recognition module is expensive, and most adjustments are achieved by mechanical modules, which requires avoiding the recognition module to prevent mechanical parts from colliding with the recognition module. If the collision causes damage to the recognition module, it will result in loss.
