Abstract

Welding equipment for cell modules comprises a rack, a conveying mechanism for conveying to-be-machined pieces, a welding mechanism, a visual positioning and detecting mechanism and a control system; the conveying mechanism comprises a feeding mechanism for conveying the to-be-machined pieces for feeding as well as a cell module positioning mechanism for positioning the to-be-machined pieces for positioning welding by the aid of the welding mechanism; the visual positioning and detecting mechanism positions and finds out first welding points on the to-be-machined pieces and determines relative coordinates of other welding points with the first welding points used as datum points; and the control system controls the welding mechanism to perform welding according to the relative coordinates. With the equipment, the first welding points of the workpieces are positioned and found out through the visual positioning and detecting mechanism and are used as the datum points for determining of the relative coordinates of other welding points, the welding mechanism is controlled to perform welding according to the relative coordinates, the coordinates of other welding points are convenient to determine for positioning welding, the feeding mechanism performs feeding automatically, and the cell module positioning mechanism positions the cell modules automatically, so that the positioning precision and the machining efficiency are improved.

Description

technical field [0001] The invention relates to the field of new energy battery manufacturing, in particular to a battery module welding equipment. Background technique [0002] In the production process of new energy battery packs, the most important process is the welding of the nickel sheet and the positive and negative electrodes of the circular battery. The most common welding method for this process is resistance welding. [0003] During the resistance welding process of battery pole pieces and nickel sheets, manual feeding is generally used. The product is manually placed on the equipment, the product is clamped and fixed, and then welded. After the welding is completed, the product is manually taken out. And in the process of resistance welding, there are several factors that are crucial to welding quality: welding discharge voltage, welding pressure and welding pin of welding head, which are basically not detected and controlled in the existing welding process.
