Description

Technical Field

[0001] The invention relates to the field of network transformer manufacturing, and in particular to a welding device for a network transformer coil. Background Art

[0002] A network transformer is an electronic component that is often used in network equipment. It can achieve filtering and voltage transformation functions through the internal coil. In the production process of network transformers, manual winding is often required to fix the coil on the pins, and then manual welding is used to connect the coil and the pins to form a circuit and fix them. However, manual welding is inefficient, and due to the small size of the network transformer, it is easy to cause inaccurate positioning during manual welding, resulting in loose welding.

[0003] A network transformer welding fixture tooling proposed in CN201911170888.2 includes a base, the outer walls at both ends of the top of the base are fixedly connected with nuts, a screw is arranged inside the nut, the screw and the nut are rotatably connected, the end of the screw away from the nut is fixedly connected with a rotating block, the outer wall of the rotating block is fixedly connected with a plurality of rotating rods, a workbench is arranged between the two sides of the nut, the outer wall of the bottom of the workbench and the outer wall of the top of the base are fixedly connected, a mobile platform is arranged on both sides of the top of the workbench, a plurality of slots are provided on the top of the mobile platform, a groove is provided at the bottom of the mobile platform, and a magnetic strip is arranged inside the groove. The invention is mainly provided with three main fixing mechanisms: a bolt fixing mechanism, a slot and a magnetic strip. By providing a fixing mechanism with a triple combination of a bolt fixing mechanism, a slot and a magnetic strip, the fixing quality can be effectively improved, thereby improving the welding quality.

[0004] For another example, CN202110976948.0 proposes a batch automatic welding system for network transformers, including multiple welding positions and a transformer absorber, wherein the transformer absorber includes an adsorption area and a pair of handles located at both ends of the adsorption area, and the adsorption area has magnetic force; each welding position includes a welding device and a conveyor belt arranged under the welding device, one end of the conveyor belt is a grabbing and positioning area, and the other end is a loading and unloading area, and the conveyor belt is provided with an adsorption area carrier; the welding system also includes a robotic arm that can grab the transformer absorber and a robotic arm control module. This invention uses a magnetic transformer absorber to perform batch adsorption welding on network transformers. The robotic arm, conveying device, welding device, etc. only need to operate the transformer absorber, which simplifies the structure and operation process. Batch welding can be performed automatically during welding, which greatly improves production efficiency.
