Problems solved by technology
[0003] The outline of the septum cannot be photographed as it is penetrated by X-rays
The existing battery cell measurement method can only measure the distance between the negative electrode and the positive electrode
And due to the influence of magnification, the detector can only take images of the electrodes at both ends of the cell, and cannot capture the outline of the entire cell, so it is impossible to obtain the respective widths of the diaphragm, positive electrode and negative electrode, and the width of the diaphragm and the positive electrode. and the distance between the separator and the negative electrode

Embodiment Construction
[0044] Please refer to Figure 1 to Figure 5 As shown, the present invention discloses a cell detection device and a cell measurement method. Please refer to figure 2 and Figure 4 As shown, the cell 100 includes a separator 101, a positive electrode sheet 102 and a negative electrode sheet 103 wound together, wherein the width W1 of the separator 101 is greater than the width W2 of the positive electrode sheet 102, and the width W2 of the positive electrode sheet 102 is greater than the width of the negative electrode sheet 103 W3. In one embodiment of the present invention, the cell 100 is a cylindrical cell.
[0045] The battery detection equipment includes a blanking conveying mechanism 1, a battery grasping mechanism 2 for grasping and placing the wound battery 100 on the blanking conveying mechanism 1, and a battery grasping mechanism 2 for moving along the width direction of the battery (i.e. Axially) the first cell edge adjustment assembly 3 and the second cell ed...

A method for measuring a battery cell, which includes the following steps: S1: moving the battery cell to be tested to a feeding conveying mechanism; S2: when the battery cell to be tested reaches a first detection position, the edge of the first battery cell is adjusted The components move and respectively lean against the two ends of the diaphragm of the cell to be tested; S3: The image acquisition device takes a picture of one end of the cell to be tested, and calculates the distance between the diaphragm and the positive and negative plates to judge the battery to be tested. Whether the quality of one end of the cell is qualified; S4: When the cell to be detected reaches the second detection position, the edge adjustment component of the second cell moves to respectively abut against the two ends of the diaphragm of the cell to be detected; S5: Image acquisition The device takes a picture of the other end of the cell to be tested, and calculates the distance between the diaphragm and the positive and negative plates to judge whether the quality of the other end of the cell to be tested is qualified. Compared with the prior art, the present application solves the difficult problem of measuring the diaphragm in the industry.
Description
technical field [0001] The invention relates to a method for measuring an electric core, in particular to a method for measuring a diaphragm. Background technique [0002] The separator, the positive electrode sheet, the separator, and the negative electrode sheet are wound together to form a cell. In the production process of cell winding, the distance between the positive electrode sheet and the negative electrode sheet of each layer and the distance between the separator and the positive and negative electrode sheets determine the quality of the battery. [0003] Because the septum is penetrated by X-rays, the outline of the septum cannot be photographed. The existing battery cell measurement method can only measure the distance between the negative electrode sheet and the positive electrode sheet. And due to the influence of magnification, the detector can only take images of the electrodes at both ends of the cell, and cannot capture the outline of the entire cell, so...
