Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to welding equipment for ceramic heating element pins. Background Art

[0002] A ceramic heater is a medium that can make a heating wire generate heat after being energized. Ceramic heaters are widely used in life, for example, in atomizers, especially as ceramic heating cores in electronic cigarette atomizers. In the production process of ceramic heaters, corresponding welding equipment is required to perform pin welding on the two ends of the ceramic heaters. After searching, a Chinese patent publication number CN216298217U discloses a welding device for ceramic heater pins, including a frame, and a pin feeding device and a pin folding test device on the frame. The pin feeding device includes a cutting feeding chuck and a welding feeding chuck. The welding feeding chuck is located on the pin feeding side of the cutting feeding chuck. The cutting feeding chuck is arranged on a cutting feeding slide. The cutting feeding slide is driven by a cutting feeding slide cylinder to slide back and forth toward the spot welding station. Although this technical solution can automatically perform pin welding and bending on ceramic heating elements, there is only one processing station when in use. Therefore, each time after processing one, unloading and loading operations are required, and continuous processing cannot be performed, thereby reducing work efficiency. In addition, when in use, each structure is fixed and cannot be adjusted, which makes it inconvenient to weld ceramic heating elements of different specifications, and the cutting length of the pin cannot be adjusted.

Although this technical solution can also realize automatic pin welding of ceramic heating elements, it also has only one processing station, which will also reduce work efficiency.
