Abstract

The invention belongs to the technical field of welding of batteries, and particularly relates to a laser welding clamp for a soft package battery. The laser welding clamp comprises a base, a battery cell limiting assembly, a battery protection plate, a battery protection plate limiting assembly and a start switch, wherein the battery cell limiting assembly is slidably connected to the base; the battery protection plate limiting assembly is installed on the battery cell limiting assembly and used for positioning the battery protection plate; the battery cell limiting assembly comprises a bottom plate; a positioning groove capable of accommodating a plurality of battery cells is formed in the bottom plate; one end of each battery cell is provided with a lug; the lugs make contact with the battery protection plate; the battery cell limiting assembly slides on the base so that the battery cells and the battery protection plate can be moved to a welding position, and thus the bottom plate can abut against the start switch; and the start switch is electrically connected with the laser welding equipment. Before welding, the laser welding clamp provided by the invention realizes accurate positioning of the battery cells and the battery protection plate, meets the consistency requirement, improves the welding consistency, achieves laser welding by triggering the start switch, and realizes automatic welding triggering.

Description

technical field [0001] The invention belongs to the technical field of battery welding, and in particular relates to a laser welding jig for a pouch battery. Background technique [0002] As soft-pack lithium-ion batteries enter the fields of mobile phones, tablet computers, mobile power supplies, wearable devices, and electronic cigarettes, the application fields of soft-pack lithium-ion batteries in the market are becoming more and more extensive, and the demand for battery capacity is also increasing. At the same time, the demand for products with a battery output voltage higher than 4.2V is also increasing. Ordinary single-cell batteries have insufficient capacity and low output voltage, which can no longer meet market demand. [0003] In the production process of PACK batteries, the laser welding effect has a great influence on the performance of the battery; for example, when the battery tab and the battery protection board (PCB board) are welded weakly, the internal r...
