Description

Technical Field

[0001] The utility model belongs to the field of terminal welding, in particular to a novel automatic welding machine for automobile terminals. Background Art

[0002] Automotive terminals are widely used in ABS (Antilock Brake System) and ESC (Electronic Stability Controller) systems. They typically include docking terminals and mounting terminals. The mounting terminals are inserted into the circuit board to connect to the circuit board, while the docking terminals are located within the system housing and are used to connect to mating plug terminals. The docking and mounting terminals of automotive terminals are typically secured together using a welding torch. The welding torch utilizes the high current and high voltage of the welding machine to generate heat that gathers at the torch terminal, melting the welding wire. The molten wire penetrates the area to be welded, and after cooling, the objects to be welded are firmly connected. Manual welding with a welding torch is prone to poor welds due to the small size of the terminals, resulting in a high welding scrap rate, high labor intensity, and low production efficiency.
