Embodiment 1

[0065] see Figure 3 to Figure 4 As shown, this embodiment provides a method for checking and correcting tabs, which is applied to electronic equipment, such as controllers. The method includes the following steps:

[0066] Step S1: Obtain the protruding distances of the tabs of the current group of cells respectively, wherein the current group of cells includes at least two cells.

[0067] Wherein, the battery cell generally includes the positive pole tab 73 and the negative pole tab 74, so the tab protruding distance of the battery cell should include the protruding distance h2 of the positive pole tab and the protruding distance h1 of the negative pole tab. The current group of batteries includes at least two cells, and the correspondingly obtained positive tab protruding distance h2 and negative tab protruding distance h1 are at least two respectively. The protruding distance of the tabs of the current group of batteries can be obtained sequentially according to the order...

Abstract

The invention relates to the technical field of winding machine automation, and discloses a tab inspection and correction method and device. The tab inspection and correction method analyzes the consistency of the tab detection distance of the current group of batteries, and when the consistency of the tab detection distance of the current group exceeds a predetermined threshold range, an unstable message is output to prompt the operator to check the reason; When the consistency of the protruding distance of the tabs of the current group of cells meets the predetermined threshold range, the next group of cells is obtained by combining the input deviation correction value of the pole piece of the current group of cells with the adjustment value of the protruding distance of the tabs of the current group of cells The input deviation correction value of the pole piece, in this way, provides a more reliable deviation correction value for the next set of pole pieces to ensure that the pole piece input position is more accurate, thereby improving the consistency of the protruding distance of the pole piece and ensuring the quality of the battery cell.

Description

technical field [0001] The invention relates to the technical field of winding machine automation, in particular to a tab inspection and correction method and device. Background technique [0002] The tab is a part of the lithium-ion polymer battery. The battery is divided into positive and negative electrodes. The tab is the metal body that leads the positive and negative electrodes out of the battery cell. [0003] Existing lithium batteries are usually processed by winding machines, such as figure 1 As shown, the distance from the top side edge of the protruding protective film (Sealant) of the positive and negative tabs of the battery core after winding to the edge of the diaphragm is called the protruding distance of the tab, also known as the tab height or Tab exposed size, tab protruding distance includes positive tab protruding distance and negative tab protruding distance. In actual processing and production, the size of the protruding distance of the positive tab...
