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 checking and correcting method and device. According to the tab checking and correcting method, consistency analysis is carried out on the tab extending distances of the current group of battery cells, and when the consistency of the tab extending distances of the current group of battery cells exceedsa preset threshold range, unstable information is output to prompt an operator to check reasons; when the consistency of the extending distances of the tabs of the current group of battery cells conforms to a preset threshold range, the input deviation rectifying value of the current group of battery cell pole pieces is matched with the tab extending distance adjusting value of the current group of battery cells, and the input deviation rectifying value of the next group of battery cell pieces is obtained, so that a more reliable deviation correction value is provided for the next group of pole pieces, and the more accurate input position of the pole pieces is ensured, so that the consistency of the tab extending distance is improved, and the quality of the battery cell is ensured.

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...
