[0002] The Chinese name of PCB board is printed circuit board, also known as printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. During the production and processing of PCB board, the PCB board and the protective plate need to be encapsulated to protect the PCB board. There are welding blocks on the PCB board and welding holes on the protective plate. When encapsulating the PCB board and the protective plate, the welding blocks need to be accurately placed inside the welding holes. When there is a placement deviation, the welding blocks will be tilted and cannot be inserted into the welding holes.

[0003] Currently, when inserting the welding block into the welding hole, the PCB board is directly placed on the operating table. There is a lack of clamping and stabilizing measures, so the PCB board cannot be kept stable. It is easy to shake during welding and packaging, which causes the welding block to be unable to be accurately inserted into the welding hole, affecting the packaging. For this reason, we propose a PCB packaging machine with high packaging stability. Utility Model Content
