Technical Field

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It is mainly composed of a primary coil, a secondary coil, and an iron core. During operation, the transformer generates heat, causing the temperature to rise. To cope with this phenomenon of thermal expansion and contraction, the transformer is usually equipped with an oil pillow. The corrugated sheet is an important component of the oil pillow. Its main function is to provide space for thermal expansion and contraction and help dissipate heat. After extrusion, the corrugated sheet needs to be welded to seal its edges.

[0003] At present, the welding device in the existing technology mainly includes a support frame and a welder body. The corrugated sheet molded part is placed above the support frame. After the molded part body contacts the welding gun of the welder body, it moves up and down to perform edge welding on the molded part. In the process of the welder welding the edges of the molded part one by one, it is necessary to accurately control its movement process to prevent the deviation between the welding gun of the welder and the weld seam of the molded part. Precise movement control of the molded part requires the addition of more displacement sensors, which increases the cost of the device. When the specifications of the molded part change, the various data of the displacement sensors need to be adjusted. The operation process is relatively cumbersome, which affects the efficiency of the device in welding the corrugated sheet.

[0004] Therefore, in order to solve the above problems, a corrugated sheet welding device for a transformer is proposed. Utility Model Content
