Description

Technical Field

[0001] The utility model relates to the technical field of spot welding equipment, in particular to an automatic spot welding equipment based on cabinet rear door welding. Background Art

[0002] The cabinet rear door is a sheet metal-like protective object, which is often installed at the rear of the cabinet. Parts on which other parts are installed often need to be welded, and welding needs to be performed on a spot welding machine. Spot welding machines are mostly used to weld at a certain point. For some parts, there are many places that need to be welded. The parts that need to be welded are moved in a single direction.
