The embodiment of the invention discloses a battery welding device and a welding method thereof. The battery welding device includes: a fixed table, including a base and a fixed bracket; a first linear motion device, which can drive the battery relative to the base Perform linear reciprocating motion; second linear motion device; rotating device, connected with the second linear motion device, the rotating device can be driven by the second linear motion device to perform linear reciprocating motion relative to the fixed bracket, the direction of motion of the rotating device is the same as that of the battery to be welded The movement direction of the laser welding device is vertical; with the cooperation of the first linear movement device, the second linear device and the rotation device, the laser welding device can move relative to the side wall of the battery to be welded, and the laser direction of the laser welding device is always in line with the side wall The walls are vertical. The embodiments of the present invention improve the welding efficiency, and at the same time can ensure that the welding speed is stable and consistent, and improve the welding quality of the fillet part of the battery.
Description
technical field [0001] The invention relates to the technical field of welding equipment, in particular to battery welding equipment and a welding method thereof. Background technique [0002] With the vigorous development of the new energy market, the energy density of lithium-ion batteries continues to increase, while the volume of batteries is also increasing. Commonly used rectangular batteries usually include a connected casing and a top cover, as well as a plurality of single cells housed inside the casing, wherein the casing and the top cover are generally made of metal materials, so that the battery has a strong resistance Transformation ability, thereby enhancing its safety. The shell and the top cover can be connected by welding, often using laser welding. This welding method has a good welding effect and is suitable for precision welding of seams. [0003] One of the commonly used welding methods for rectangular batteries is side seam welding. In the process of...
