Abstract

The invention discloses a direct spot welding device and method of a button lithium battery. The spot welding device comprises a spot welding disk which is provided with a center gear, an annular slide track and four triangular bosses as well as a plurality of elliptical gears engaged with the center gear, and the spot welding disk is externally provided with a feeding manipulator, a first leg feeding and welding mechanism, a second leg feeding and welding mechanism and a discharge manipulator; the method comprises the steps that the elliptical gears are driven by the center gear to rotate around the center gear circumferentially, and the position of accommodation plates on the elliptical gears changes when the elliptical gears pass through each triangular boss; a battery body is placed in a holding tank through the feeding manipulator, and one side, relative to the battery body, of the first leg feeding and welding mechanism is welded with a first leg; and the other side, relative to the battery body, of the second leg feeding and welding mechanism is welded with a second leg, and the battery body is discharged by the discharge manipulator upon completion of welding of the legs at both sides.

Description

technical field [0001] The invention relates to a spot welding machine and a spot welding method thereof, in particular to a button-shaped lithium battery double-sided spot welding device and a spot welding method thereof. Background technique [0002] During the production of lithium batteries, it is necessary to weld the tabs and cover plates above the metal mandrel of the lithium battery, which is generally performed on a laser welding machine. The laser welding machine includes a laser generator, a laser head, and a movable mount for fixedly installing a lithium battery, tabs and cover. The staff first fixes the lithium battery, tabs and cover on the movable mount, and then pushes the movable mount To the right below the laser head, so that the laser head and the cover are arranged accordingly. For example, the existing Chinese invention patent publication No. CN104259660A "A Lithium Battery Welding Equipment" includes a lithium battery clamping device, a conveying devi...
