Description

Technical Field

[0001] The utility model relates to the technical field of resistance welding, in particular to an automatic resistance welding machine. Background Art

[0002] Resistors are often simply called resistors in daily life. They are current-limiting components. When connected to a circuit, the resistor's resistance is fixed. It typically has two pins and limits the current flowing through the connected circuit. Soldering a resistor to a circuit requires a welding machine.

[0003] Existing welding machines require manual operation, have a low degree of automation, and are labor-intensive during welding. Moreover, existing welding machines only perform single-channel welding, which reduces the work efficiency during resistance welding. At the same time, since the entire welding process requires manual operation, the welding position is not accurate enough, and welding misalignment is likely to occur, thereby reducing the yield rate during welding.

[0010] Preferably, the wiring board loading mechanism is composed of a loading rack, a linear module, a wire moving plate lifting assembly and a rotating conveying assembly. The loading rack is fixedly connected to the surface of the frame, and a linear module is installed on the surface of the frame and on one side of the loading rack.

The resistors and wiring board are welded by the welding head assembly. After welding is completed, automatic stacking and material collection are realized; the present invention improves the degree of automation of the welding machine, and does not require manual auxiliary operation during the welding process, thereby reducing labor intensity; and the welding machine adopts dual-channel welding, which improves work efficiency; at the same time, since the entire welding process is automatically completed by the machine, there is no manual operation in the middle, so the position during welding is more accurate, thereby increasing the yield rate during gluing.
