Description

Technical Field

[0001] The utility model relates to the technical field of bolt welding detection, in particular to a welding bolt detection mechanism. Background Art

[0002] In existing stud welding production lines, stud welding error prevention often relies on manual identification during production or adding a process for manual marking and full inspection. There is no way to detect whether the incoming semi-finished product, consisting of four bolts, has any leaks in this process, and there is no way to detect whether the three studs welded in this process have any leaks either. It relies entirely on manual marking and inspection. This method has low production efficiency and is prone to errors, resulting in defective outflows. It is also easy for human factors to affect product quality. In addition, as customers' quality requirements continue to increase, higher requirements are placed on the stability of the manufacturing process. Although the existing technical error prevention solutions can achieve error prevention functions to a certain extent, the equipment still seems unable to cope with complex scenarios with multiple abnormal state requirements, resulting in problems such as leaks.
