[0002] With the rapid development of modern electronic technology, the assembly density and complexity of electronic products are increasing. Traditional electronic component assembly methods, such as plug-in assembly, can no longer meet the high-density and high-reliability requirements of modern electronic products. Therefore, surface mount technology (SMT) came into being and quickly became the mainstream technology in the field of electronic assembly. SMT technology achieves high-density assembly of electronic products by directly mounting miniaturized electronic components on printed circuit boards (PCBs) or other substrates, greatly improving assembly efficiency and reliability.

[0003] There are still some challenges in the SMT welding and assembly process. When welding components on a circuit board, the circuit board is usually placed on an operating table and then welded. In this way, the position of the circuit board may be shifted due to other factors during the welding process, thereby affecting the welding accuracy. In addition, the efficiency of welding and assembly in a single operation is relatively low. Utility Model Content
