Description

Technical Field

[0001] The utility model relates to the field related to welding spot monitoring, in particular to an automatic welding spot detection device. Background Art

[0002] Electric welding can generally be divided into two types: resistance welding and arc welding. Resistance welding refers to a welding method that uses a cylindrical electrode to form a weld between the contact surfaces of two overlapping workpieces. It is also called spot welding. During spot welding, pressure is first applied to make the workpieces in close contact, and then the current is turned on. Under the action of resistance heat, the contact between the workpieces melts and forms a weld after cooling. The quality inspection of the weld is necessary to ensure the integrity and reliability of the welding structure.

[0003] The improvements to the welding spot detection device in the prior art are mostly reflected in the detection device. For example, the Chinese patent document with publication number CN211086119U discloses a welding spot image detection device, which includes: a base; a bracket, the base carries the bracket; a lighting unit, connected to the bracket; a moving unit, the bracket passes through the moving unit and can move along the axial direction of the bracket; a fixed base plate, connected to the moving unit and provided with a slide groove; a first fixed jaw, fixed to the first end of the fixed base plate; a second fixed jaw, fixed to the second end of the fixed base plate; a sliding jaw, sliding along the slide groove; a positioning bolt, passing through the second fixed jaw and abutting against the sliding jaw; a camera, located between the first fixed jaw and the sliding jaw, and the camera is clamped by the distance between the first fixed jaw and the sliding jaw. The welding spot image detection device can make the camera fixed or active by adjusting the sliding jaw. When the sliding jaw does not fix the camera, the camera can be adjusted to a suitable shooting angle, and then the camera is fixed, so that the workpiece can be detected from multiple angles.
