Lithium battery automatic assembly equipment and assembly method

Abstract

The invention relates to the technical field of lithium battery assembly, in particular to an automatic lithium battery assembly equipment and assembly method, including a support frame, a conveying mechanism and a discharging mechanism. The capping mechanism is used to continuously cover the end cover of the battery core on the corresponding battery cell after the assembly is completed. The cover can be accurately clamped on the battery core, which avoids the problem that the end cover is difficult to be stuck on the battery core due to inaccurate alignment between the end cover and the battery core. Each fixed group plate is fixed to ensure that the fixed group board will not move due to transportation during the entire transportation process, ensuring the accuracy of subsequent battery cell insertion, and avoiding the difficulty of ensuring the precise alignment of the battery cell and the battery cell fixing plate Problem with inserting into the jack.

Description

technical field [0001] The invention relates to the technical field of lithium battery assembly, in particular to an automatic lithium battery assembly equipment and an assembly method. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and uses a non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metal state Lithium, and it is rechargeable. Lithium-ion batteries are mostly rectangular structures. Lithium-ion batteries can be directly made into a whole rectangular structure, or can be made by assembling multiple individual lithium battery cells and then fixedly connecting the positive and negative electrodes. .

Problems solved by technology

[0003] The Chinese invention patent with the application number CN113381053A discloses a lithium battery module manufacturing, production and assembly equipment and assembly method. Aiming at the problems of troublesome operation, low assembly efficiency and failure to realize streamlined automatic assembly in the process of relying on manual assembly in the assembly process of power cells

[0004] But use above-mentioned method to exist following problem in the process of lithium battery assembly: 1, when the assembled battery core is pressed on end cover, can't realize continuous capping work, when the assembled battery core is pressed on end cover simultaneously, The inaccurate alignment between the end cap and the battery cell makes it difficult for the end cap to be stuck on the battery cell, making it difficult for the assembled battery cell to achieve the effect of capping and pressing

[0005] 2. When multiple battery cells arranged in a matrix are integrally clamped from the outside, since the internal battery cells are not directly in contact with the clamping parts, it is prone to the problem that the battery cells in the middle part are less stressed and cause the problem of sliding, thus Unable to achieve the effect of integral assembly

[0006] 3. There is no limit in the process of transporting the battery cell fixing plate from one side to the bottom of the assembly area, and it is difficult to ensure the precise alignment of the battery cell and the battery cell fixing plate, so it is easy to cause the battery core to not be inserted into the socket accurately
