Description

Technical Field

[0001] The invention relates to the technical field of production welding, and in particular to an automatic slag removal shell welding device for power adapter production. Background Art

[0002] With the widespread popularity of electronic devices such as smartphones, tablets, laptops, security cameras, routers, etc., the demand for power adapters continues to grow. In order to meet the needs of large-scale production, more efficient and stable production equipment is needed to improve the production efficiency and quality of power adapters, including devices for welding power adapter shells. Consumers have higher and higher requirements for the quality and appearance of power adapters. The shell of the power adapter not only plays a role in protecting the internal electronic components, but also needs to have good sealing and aesthetics.

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

[0004] Most existing devices use a single welding head moving along the gap to weld. Most existing technologies are similar to a power adapter production welding device. The structure with publication number CN113618322A includes a main box, a support assembly is installed on the main box, and the power adapter is arranged on the support assembly; an operating box is installed inside the main box, and a fastening assembly is installed on the operating box; a welding assembly is installed on the fastening assembly; and a position change assembly is installed inside the operating box. The power adapter production welding device can press the power adapter through the fastening assembly to facilitate the welding assembly to perform welding operations on the power adapter. However, there are still areas that can be optimized in the device.

[0005] The existing device mainly manually controls the feeding of the plastic welding tape, which makes it difficult for some devices to stably convey the plastic welding tape to the left, resulting in inconvenience in evenly filling the hot-melt plastic into the adapter shell joint. Secondly, some devices mainly use fixed welding heads to hot-melt the plastic welding tape, which makes it easy for the outer wall of some welding heads to accumulate welding slag and affect heat conduction, resulting in inconvenience in stably heating the plastic welding tape to a suitable temperature. Finally, some welding heads will continuously accumulate layers 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 device. Therefore, in order to solve the above problems, an automatic slag discharge shell welding device for power adapter production is proposed. Summary of the invention
