[0002] Circuit board printing is a process of connecting electronic components to each other by etching or photosensitively printing conductor patterns on an insulating substrate. During the printing process, the insulating substrate needs to be fixed. Existing circuit board printing devices, such as a supercomputer circuit board printing device disclosed in application number CN202322681049.5, will be squeezed into a circular groove by a suction cup, and the lower surface of the circuit board will be fitted and connected to the top of the workbench. The clamping effect of the limit block and the suction effect of the suction cup will jointly improve the stability of the circuit board when working on the workbench, making it convenient for the circuit board to be printed stably.

[0003] However, in the actual printing process, which includes multiple steps such as drilling, etching, and cleaning, the existing printing device uses a structure that fixes the substrate and can only clamp a single set of circuit boards, resulting in frequent clamping during the production process, complex operation, low efficiency, and waste of manpower. In addition, one side of the circuit board will contact the workbench, making it inconvenient to process that side, and thus it is not suitable for use in printing multi-layer circuit boards. To this end, we propose a circuit board printing device to solve the above problems. Utility Model Content
