Problems solved by technology
[0003] However, placing the laser welding head of the laser welding device in the glove box in the prior art has the following problems: in order to adapt to the space required by the laser welding head, it is necessary to increase the size of the glove box and increase the sealing elements to ensure the safety of the glove box. Sealing effect, which increases the manufacturing cost and makes the structure of the glove box complicated; in addition, the size of the glove box increases and the laser welding head of the laser welding device is placed in the glove box, so that the operator cannot quickly put the sodium nickel into the glove box. The welding part of the battery is aligned with the laser welding head, thereby reducing the welding work efficiency

A laser welding device for packaging the positive electrode chamber of a sodium-nickel battery, comprising a support base, a laser welder, a controller, an electric workbench and a glove box arranged on the electric workbench, the laser welder is fixedly arranged on the support base, The front end of the laser welder is fixed with a laser transition arm, and the laser transition arm is vertically set downwards so that the laser head is facing the top of the glove box, and the laser head is facing the positive electrode of the sodium-nickel battery to be welded in the glove box. The laser can pass through the upper panel of the glove box and enter the glove box, and the welding is completed under the vacuum environment of the sodium-nickel battery, which is convenient for operation and has a good welding effect.
Description
technical field [0001] The invention relates to the technical field of sodium-nickel battery processing, in particular to a laser welding device for the packaging of a positive electrode chamber of a sodium-nickel battery. Background technique [0002] The sodium-nickel battery is a battery composed of sodium for the negative electrode, nickel chloride for the positive electrode, and ceramic alumina for the electrolyte. Since the filling and laser welding of the positive electrode material of the sodium-nickel battery have very high requirements on the accuracy of the equipment and the environment, Therefore, in the preparation process of the positive electrode material of the sodium-nickel battery, not only the particle size of the powder needs to reach the micron level, but also the laser welding head of the laser welding device is set in the glove box during the welding process, so as to realize the loading and unloading of the positive electrode material of the sodium-nic...
