[0002] Exposure machine is an indispensable equipment for modern manufacturing of printed circuit boards (PCB). One of the most critical processes in the manufacturing process of printed circuit boards is to transfer the negative image to the copper foil substrate. First, a layer of photosensitive material is coated on the substrate, and then the photosensitive material coated on the substrate is irradiated with light to change its solubility. The resin in the unexposed part is not polymerized and is dissolved under the action of the developer. The resin in the photosensitive part remains on the substrate to form an image. This process is exposure, which is the process completed by the exposure machine in the production of printed circuit boards.

[0003] When the exposure machine in the prior art is in use, a PCB board is first placed on the tooling mechanism, and then the tooling mechanism drives the PCB board to move into the exposure machine, and waits for the exposure to be completed. The tooling mechanism drives the PCB board out of the exposure machine, and then the PCB board after the exposure is removed. However, working in this way will waste some time for loading and unloading materials, and also waste some time for waiting for exposure. The overall time wasted is relatively large, and the processing efficiency is low. Summary of the invention
