Technical Field

[0001] The utility model relates to the technical field of lithium battery processing, in particular to a lithium battery spot bottom welding device. Background Art

[0002] Lithium batteries are batteries with metallic lithium as the negative electrode. During the processing of lithium batteries, in order to connect multiple cylindrical lithium batteries during processing, a bottom welding device is used to weld and fix several lithium batteries together.

[0003] When processing lithium batteries, traditional bottom welding devices first take out several cylindrical lithium batteries according to actual processing needs, arrange the cylindrical lithium batteries in a row and place them on the processing table, then place the welding rod on top of the row of lithium batteries, and then place the lithium batteries under the welding gun head. As the welding gun head and the welding rod come into contact, the lithium batteries are slid and displaced to complete the bottom welding operation. However, in the actual operation process, it was found that when a row of lithium batteries was moving, due to the lack of corresponding limiting components, the arrangement of the lithium batteries was deviated and misaligned, which affected the bottom welding effect and caused abnormalities in the normal use of the subsequent lithium batteries, reducing the practicality of the bottom welding device. Utility Model Content

[0016] The effect achieved by the above components is that when the bottom welding device is in use, the staff is unlikely to accidentally touch the control panel, causing abnormal operation of the welding gun head, thereby ensuring the normal electric welding processing of the device on the lithium battery.

[0017] Preferably, a shift block is fixedly connected to one side surface of the protective plate, and the surface of the shift block is provided with anti-slip stripes.
