Positioning device for laser welding of lithium thionyl chloride battery

Abstract

The utility model relates to the technical field of lithium thionyl chloride battery production, in particular to a positioning device for lithium thionyl chloride battery laser welding, which comprises a bottom frame and a battery shell, a positioning mechanism is arranged on the bottom frame and is used for positioning the battery shell, and the positioning mechanism comprises a conveying component, a positioning component and a positioning component, the loading assembly is arranged on the conveying assembly and is used for loading the battery shell; the fixing assembly comprises a bottom plate arranged on the conveying assembly, sliding frames are slidably installed at the two ends of the bottom of the bottom plate, first supporting rods are pivoted to the two ends of the bottom of each sliding frame, second supporting rods are pivoted to the outer ends of the first supporting rods, and positioning pieces are installed at the four corners of the bottom plate; when the sliding frame moves, the second supporting rod is driven to rotate through the first supporting rod, the second supporting rod drives the positioning plate through the shaft rod to accurately position the loading assembly, and the position consistency in the laser welding process is ensured; and moreover, through synchronous movement of the four positioning pieces, symmetrical clamping is achieved, and the positioning precision and stability are improved.
