Description
Technical Field
The invention relates to the technical field of battery manufacturing, in particular to an on-line detection device and method for baking a battery cell.
Background
The vacuum baking is a procedure for manufacturing batteries in the new energy lithium battery industry, and the requirements are very strict. The purpose of vacuum baking is to evaporate water of the pole pieces in the battery cell, so that the process effect of the subsequent battery cell processing procedure is prevented from being influenced by the excessive water content. Therefore, how to accurately detect the water content of the battery while baking the battery cells is becoming an important concern to those skilled in the art.
In the prior art, the method for testing the water content of the battery cell is to manually put a false battery cell (the battery cell to be tested for the water content), manually take out the false battery cell after the vacuum baking process time is finished, insert a formation nail and send the formation nail to a water content testing room for disassembly, and the whole disassembly process is about 20 minutes. This process of baking and testing for water content dyssynchrony has the following drawbacks.
1. The precision is low: the process increases too many uncontrollable factors from the putting of the battery cell to the subsequent disassembly, such as workshop environment change, manual disassembly speed and the like, and the water content of the battery cell is easily influenced;
2. poor pertinence: the false cell is selected by randomly selecting one cell, disassembling the single cell, and taking the disassembled result of the cell as the water content result of the whole oven cell, wherein the internal details of each cell are different, the states of the cells at different distances from a vacuum exhaust port of the equipment are also different, and the real result of each cell with the measured water content is difficult to ensure;
3. the efficiency is low: the battery is disassembled each time, the battery core is repeatedly inserted and taken by a mechanical arm, the detection time is long, and if the water content is unqualified, the battery core is required to be baked again, so that the productivity of the battery core is affected;
4. waste is high: each water content test requires disassembly of one or more cells, and the disassembled cells cannot be used, so that the cost of the cells is wasted.
Therefore, the conventional method for baking the battery cells and detecting the water content has a great disadvantage, and it is needed to provide an on-line detection device and method for baking the battery cells, so as to solve the above technical problems.
