Description

Technical Field

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

[0002] The pressure welding of lithium battery caps refers to the process of connecting the positive and negative caps of the battery to the battery shell when assembling the lithium battery. Pressure welding is a commonly used connection technology that can ensure good electrical contact and mechanical connection between the positive and negative electrodes of the battery and the battery shell. Pressure welding machines are generally used for pressure welding of lithium batteries.

[0003] At present, during the pressure welding process of lithium batteries, traditional clamps have poor clamping effect on the sides of slender lithium batteries, which will result in less than ideal pressure welding effect due to the unstable placement of the lithium batteries. The unstable clamping of the lithium batteries makes it impossible to ensure the accuracy of the placement of the lithium battery caps, and there are also errors in manually placing the caps on the end faces of the lithium batteries. After the pressure welding is completed, the staff needs to manually remove the pressure-welded lithium batteries and transfer them to the collection box, which makes the unloading process more cumbersome.

[0024] According to the above working process, it can be known that the pressure welding positioning port 15 formed between the first pressure welding guard plate 5 and the second pressure welding guard plate 6, which is smaller than the diameter of the end face of the lithium battery, can be used to place a matching cap for accurate pressure welding processing by the pressure welding mechanism 4.
