Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic coil manufacturing technology, and more specifically, it relates to an electromagnetic coil pin welding device. Background Technology

[0002] Currently, in modern electronic equipment manufacturing systems, electromagnetic coils are key fundamental components, and their performance directly affects the overall operational efficiency of the equipment. The welding quality between the electromagnetic coil pins and the coil windings determines core indicators such as the electromagnetic coil's conductivity, mechanical strength, and service life. In the field of electromagnetic coil pin welding technology, there are many technical bottlenecks that urgently need to be overcome:

[0003] Multiple sets of synchronous feeding are difficult to achieve: With the continuous expansion of the scale of electronic product production and the increasing demand for production efficiency, the existing welding equipment has significant defects in the synchronous feeding of multiple sets of coils and pins for the multi-station welding needs in mass production scenarios. It cannot perform multi-set feeding welding, resulting in low output.

[0004] Lack of effective protection measures after welding: During pin welding, the high temperature will cause the metal surface of the weld to oxidize rapidly and form an oxide layer. In the subsequent actual use of the electromagnetic coil, due to the complex environment, the welded part is easily corroded by water vapor and corrosive gases in the air, which will gradually deteriorate the conductivity of the welded part and even cause open circuit failure, greatly shortening the service life of the electromagnetic coil and affecting the reliability and stability of electronic equipment.

[0005] Poor heat dissipation and inability to handle surrounding dust: The welding process generates a lot of heat. If it cannot be dissipated in time and effectively, it will quickly accumulate in key components such as the guide seat, causing local overheating and thermal deformation. This leads to a decrease in the positioning accuracy of the electromagnetic coil and pins on the guide seat, further affecting the welding quality and creating a vicious cycle. In addition, dust is easily generated in the surrounding environment during the welding process and cannot be dealt with in time, affecting the welding quality. Utility Model Content
