During the processing, the PCB boards usually need to be taken out of the trays, placed in carriers, and bonded to the carriers. The bonding of the PCB boards to the carriers is to ensure that the PCB boards can be stably fixed on the carriers during the assembly process to prevent the PCB boards from moving or falling off. This can improve production efficiency and reduce the error rate. In order to achieve a close fit between the PCB board and the carrier, ensure that the electronic components on the PCB board will not be misplaced or damaged during the assembly process, thereby improving the quality and reliability of the entire product, a cover steel sheet is usually placed on the magnetic carrier to fix the PCB board.

[0003] Currently, the demand for PCB boards is huge, the requirements are high, and the flow speed is fast. Usually, multiple devices are needed to complete functions such as placing the PCB boards on the carrier, placing steel sheets on the PCB boards, reading codes for re-inspection, etc., which not only increases the process but also increases the equipment cost.
