Description

Technical Field

[0001] The invention relates to the technical field of electronic component welding processing, in particular to an automatic welding device for electronic components. Background Art

[0002] Electronic components are components of electronic elements and small machines and instruments. They are often composed of several parts and can be used in similar products. They often refer to certain parts of industries such as electrical appliances, radios, and instruments. They are the general term for electronic components such as capacitors, transistors, hairsprings, and springs. Electronic components are generally welded on circuit boards for use. The existing Chinese patent document with announcement number CN216264288U discloses an electronic component welding device with a positioning structure. It is proposed that a fixed plate, a measuring ruler, a fixed frame, a rotating shaft, a sliding sleeve and a pointer are set. The sliding sleeve slides on one end of the fixed column. The two sliding sleeves can be slid to adjust the distance between the two fixed frames. The pointer is fixedly set at the bottom end of the support plate and moves with the movement of the fixed frame. One side of the two pointers is in contact with the surface of the measuring ruler. The two fixed plates are respectively clamped inside the welding device body, thereby fixing the measuring ruler. Through this structure, the electronic components can be effectively positioned to a suitable position according to the pointer values ​​of the two pointers, thereby solving the problem of welding errors caused by inaccurate positioning of electronic components.

[0003] In the above scheme and the prior art, when it comes to welding electronic components and circuit boards, on the one hand, the clamping and fixing of circuit boards on welding equipment is usually only suitable for circuit boards of one specification, and the clamping work for circuit boards of different models is relatively inconvenient, and the working flexibility is poor. After welding is completed, the next circuit board needs to be installed before continuing the work, which affects the welding efficiency. Moreover, during welding, electronic components are generally first inserted into the mounting holes on the circuit board through pins, and then fixed by welding with a welding head. During this process, the welding head can easily touch the components, causing the problem of component position displacement, which in turn affects the welding quality and cannot meet actual processing needs. Improvement and optimization are needed.
