Then, the lifting seat 2 is finely adjusted based on the thickness of the PCB circuit board so that its height meets the needs of the PCB circuit board in various processes during production, such as circuit board printing, surface mount, insertion, coating and other processing steps.

[0030] In addition, the mobile power frame 4 can move horizontally on the lifting seat 2, which can meet the processing and production needs of PCB circuit boards of different widths and sizes during the PCB circuit board production process.
