Cell encasing cover-closing method

Abstract

The invention relates to a cell encasing cover-closing method. The method includes the following steps that after cells are placed on a bottom cover or an upper cover, the other half of a case is placed on the cells through a robot, and the part, on at least one of the upper side and the lower side of the cells, of the case reciprocates in the horizontal plane so as to simulate the shaking motion. The cells are finely adjusted automatically in the cover closing process to find positioning holes in the bottom cover or the upper cover by simulating the shaking motion in the cover closing process, so that the accuracy of cell alignment for cover closing in automatic production is improved, the cover closing difficulty is lowered, and thus the machining quality is improved.

Description

technical field [0001] The invention relates to a method for assembling an electric core into a casing and closing a cover, in particular to an assembly method when the electric core is put into a casing and the cover is closed. Background technique [0002] With the rapid development of clean energy and the electric vehicle industry, the application of batteries is becoming more and more extensive, especially the application of cylindrical dry batteries in electric vehicles is becoming more and more popular. For example, Tesla's special lithium battery uses thousands of 18650 batteries and assembles them into special battery panels as the power source of the vehicle, and this method has also been recognized and widely used for reference by the industry. Therefore, there is an increasing demand for battery assembly and processing in the market, and the market potential is large. At this stage, the corresponding automatic production technology and equipment are still in the i...

Problems solved by technology

Therefore, there is an increasing demand for battery assembly and processing in the market, and the market potential is large. At this stage, the corresponding automatic production technology and equipment are still in the initial stage of research and development, resulting in a vacuum period in the domestic market. Therefore, there is an urgent need A breakthrough in the automation technology of the battery finishing production link, forming the ability of continuous automatic production

[0003] Among them, the shelling link is a very important link in the battery assembly production process, that is, multiple batteries are assembled in the shell as a whole. The traditional shelling method in the industry usually adopts manual methods, which have low efficiency and poor production quality. Mostly produced in small batches

With the gradual increase of market demand, the traditional manual shelling method and production method have been difficult to meet the processing requirements, and there is an urgent need to improve the solution

[0004] Therefore, it is sought to replace the manual method with an automated solution. However, there are certain problems in automatic shell insertion. When the cover is closed, the battery cell is placed on one of the half shell covers (on the bottom cover or the upper cover), because there are many batteries. When closing the cover and placing the other half of the shell, it is often impossible to keep the battery cells neat, resulting in low accuracy when closing the cover, which is more difficult to close, and it is easy to happen that it is difficult to close the cover, thereby reducing the processing quality
