Description

Technical Field

[0001] This utility model relates to the field of metal welding technology, specifically to a reciprocating automatic spot welding device. Background Technology

[0002] In manufacturing sectors such as automotive parts processing and electronic connector production, spot welding is a core process for connecting metal components. Its welding efficiency and precision directly affect the quality of products and the overall production capacity.

[0003] Currently, most mainstream spot welding methods in the industry are still in the stage of manual operation or semi-automatic equipment. When manually spot welding, operators need to manually fix the product throughout the process. In the process of relying on manual positioning, the long-term repetitive operation can easily cause hand fatigue for operators. At the same time, visual deviation is also difficult to avoid. These factors can easily lead to the displacement of the spot welding position, resulting in a high product defect rate. While existing semi-automatic equipment has improved efficiency to some extent, it still requires manual assistance to complete operations such as changing product fixtures and adjusting welding points. It cannot achieve continuous operation of the entire process of "loading-welding-unloading". The efficiency shortcoming is particularly prominent in mass production. In addition, the fixtures of existing semi-automatic equipment are mostly fixed structures, lacking flexibility and only adaptable to single-specification products, making it difficult to meet diverse production needs.
