Description

technical field [0001] The invention relates to the technical field of PCB board processing equipment, in particular to a clamping and limiting device for PCB boards. Background technique [0002] In the process of PCB board processing, the PCB board needs to be placed on the working platform of the CNC machine tool, and the PCB board is fixed on the working platform by negative pressure adsorption. However, the PCB board will shake slightly during the processing process. This will lead to processing errors. Therefore, in the prior art, two sets of opposite pneumatic splint structures are set, and the splints are used to clamp and limit the opposite sides of the PCB board to prevent shaking. However, in this case, the splints only limit the PCB. The side of the board, during the processing process, the PCB board will still have a slight vertical square displacement, which will affect the processing accuracy. [0003] In view of the above-mentioned defects, the designer acti...
