Description

Technical Field

[0001] The present invention relates to the technical field of production welding, and particularly to an automatic slag-discharging housing welding device for power adapter production. Background Art

[0002] With the wide popularity of electronic devices such as smart phones, tablet computers, laptop computers, security cameras, routers, etc., the demand for power adapters continues to grow. To meet the needs of mass production, more efficient and stable production equipment is required to improve the production efficiency and quality of power adapters, including devices for welding power adapter housings. Consumers have higher and higher requirements for the quality and appearance of power adapters. The outer shell of the power adapter not only needs to protect the internal electronic components, but also needs to have good sealing performance, aesthetics, etc.

[0003] During the production welding process of power adapters, slag discharge is usually required. If the high-temperature welding slag generated during the welding process accumulates on the welding equipment, the slag may block the wire feeding channel, resulting in poor wire feeding; or adhere to the electrode, affecting the electrical conductivity and heat dissipation performance of the electrode, shortening the service life of the electrode, increasing the maintenance cost and downtime of the equipment. Timely slag discharge can keep the welding equipment clean and in good working condition, facilitate the heat dissipation and ventilation of the equipment, avoid overheating of the equipment caused by slag accumulation, thus ensuring the stability and reliability of the equipment performance, and improving the efficiency and quality of the welding work.

[0004] Existing devices mostly adopt the method of moving a single welding head along the gap for welding. Most of the prior art is similar to a power adapter production welding device. The structure with the publication number of CN113618322A includes a main chassis, a support assembly is installed on the main chassis, and the power adapter is arranged on the support assembly; an operation box is installed inside the main chassis, and a fastening assembly is installed on the operation box; a welding assembly is installed on the fastening assembly; a position transformation assembly is installed inside the operation box. This power adapter production welding device can press the power adapter through the fastening assembly, facilitating the welding operation of the welding assembly on the power adapter. However, there are still areas for optimization in this device.

[0005] The existing devices mainly manually regulate the feeding of plastic welding tapes, making it difficult for some devices to stably convey the plastic welding tapes to the left, resulting in inconvenience in evenly filling the molten plastic into the seams of the adapter housing. Secondly, some devices mainly use fixed welding heads to heat-melt the plastic welding tapes, making it easy for the outer walls of some welding heads to accumulate welding slag and affect heat conduction, thus making it inconvenient to stably heat the plastic welding tapes to an appropriate temperature. Finally, some welding heads will continuously accumulate layer upon layer of welding slag, making it difficult for some devices to automatically clean the welding slag on the outer wall of the welding wheel, resulting in inconvenience in crushing and collecting the welding slag, reducing the working efficiency and practicality of the devices. Therefore, to solve the above problems, an automatic slag-discharging type housing welding device for power adapter production is proposed. Summary of the Invention
