Description

Technical Field

[0001] The utility model relates to the technical field of rectifier production, in particular to a welding device for processing transformer rectifiers. Background Art

[0002] A rectifier is an electronic device used to convert alternating current into direct current. Its main function is to convert the sinusoidal wave shape of alternating current into the flat-top wave shape of direct current. In alternating current, the direction and magnitude of the current will change periodically over time, and the rectifier uses the unidirectional conductivity of semiconductor devices to allow current to flow in only one direction, thereby achieving conversion from alternating current to direct current.

[0003] According to the publication number CN220739896U, a welding device for processing transformer rectifiers is disclosed, which relates to the technical field of rectifier welding. In view of the existing transformer rectifier welding device, the rectifier needs to be frequently clamped and welded on a fixed station, which seriously affects the welding efficiency and cannot timely cool down the welded parts, which is easy to cause burns when removing the rectifier, and has certain safety hazards. The following scheme is now proposed, including a welding table, a bearing plate is rotatably installed on the upper end of the welding table, a fixed component is arranged on the bearing plate, and a cooling component is installed on one side of the bearing plate at the upper end of the welding table. In the utility model, by setting the fixed component, the rotating drive component and the cooling component on the bearing plate, not only can four rectifiers be fixed at the same time for welding in sequence, but also the welded rectifier can be cooled, which effectively improves the welding efficiency and avoids the situation of burns when removing the rectifier, thereby improving safety.

[0004] However, the above still has some shortcomings. The rectifier is placed in the fixture manually, and then a robot arm is used to drive the welder for welding. After welding, it needs to be taken out manually, which is very inconvenient and affects the welding processing efficiency. Therefore, equipment that can perform positioning, clamping and welding in a flow process is needed to improve the welding efficiency of the rectifier. Utility Model Content
