Embodiment Construction

[0019] Such as figure 1 The shown method for assembling the tabs of a lithium ion battery includes the following steps:

[0020] Step one, insert the battery into the fixture.

[0021] After the positive and negative plates of the lithium-ion power battery are laminated by the automatic laminator, a rectangular bare cell with a certain thickness is formed. The cell with the outer diaphragm is pasted with a piece of adhesive tape on the overlap of the outermost layer. In order to ensure that the diaphragm does not loosen, at this time, the alignment of the positive and negative electrodes or the alignment with the diaphragm is up to the standard. To ensure that the alignment of the battery will not be affected in the subsequent process steps, The cell is fixed in the fixture, and the actions of each station are completed step by step. The fixture is not opened until the entire cell has been glued. Such as figure 2 As shown, the clamp includes a clamp cover 05, a download tool 06, ...

Abstract

The invention discloses a method for assembling lugs of a lithium ion battery, which comprises the following steps of: (1) positioning and fixing a battery cell by a clamp; (2) welding metal bands of the lugs on the end parts of the battery cell; (3) detecting and testing the battery cell; and (4) releasing the battery cell from the clamp. In the method, the battery cell is fixed by the clamp at one time in the overall process, namely prewelding the lugs, resisting adhesion, trimming the lugs, welding the metal bands of the lugs, rubberizing and testing, so that the displacement phenomenon of the lugs of the battery cell caused by joining and conversion of a process is avoided, and the assembly quality and the efficiency are improved.

Description

Technical field [0001] The invention relates to a method for assembling a tab of a lithium ion battery. Background technique [0002] At present, based on the many advantages of lithium-ion batteries, the development, promotion and application of lithium-ion batteries have developed rapidly. Lithium-ion batteries are widely used as power sources for many electronic devices and digital products such as mobile phones, notebook computers, electric bicycles, electric vehicles, aerospace, etc. [0003] In the production process of lithium-ion batteries, the welding of the positive and negative plates and the positive and negative lugs is basically manually positioned, and a series of procedures such as pre-welding of the lugs, welding of the metal strips of the lugs, glue and testing are completed. At present, in these processes, manual positioning is used. Before each process starts, fixing measures need to be taken to ensure that the alignment of the positive and negative plates and ...
