Embodiment Construction
[0110] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0111] see figure 1 , an embodiment of the present invention provides a method for measuring the flatness of tabs, including:
[0112] S1. Establish a standard 3D lug flatness model pool;
[0113] S2. Obtain the model information of the tab to be measured;
[0114] S3. Obtain the standard 3D tab flatness model corresponding to the model information in the standard 3D tab flatness model pool according to the model information;
[0115] S4. Scan the tab to be measured to generate a 3D flatness model of the tab to be measured;
[0116] S5. Overlap the standard 3D tab flatness model with the 3D tab flatness model to be measured, and obtain the tab height deviation in...

The invention provides a method and a device for measuring the flatness of a tab. The method comprises the following steps of S1, establishing a standard 3D tab flatness model pool, S2, acquiring model information of a to-be-measured tab, S3, acquiring a standard 3D tab flatness model corresponding to the model information in a standard 3D tab flatness model pool according to the model information, S4, scanning the to-be-measured tab, and generating a flatness model of the to-be-measured 3D tab, S5, overlapping the standard 3D tab flatness model with the to-be-measured 3D tab flatness model to obtain tab height deviation information of the to-be-measured 3D tab flatness model relative to the standard 3D tab flatness model, and S6, calculating the flatness of the to-be-measured tab according to the tab height deviation information. The method is used for eliminating the influence of a workbench, a clamp and other devices on the measurement precision of the flatness of the tab during manual operation, and can improve the measurement efficiency and meet the production requirements.
Description
technical field [0001] The invention relates to the field of tab flatness measurement, in particular to a tab flatness measurement method and a measurement device. Background technique [0002] After the polymer lithium-ion battery is manufactured, it needs to go through the packing process such as tab transfer welding to make a finished battery that can be directly applied. During the manufacturing process of the polymer lithium battery, there are many charging and discharging processes and voltage fluctuations. Resistance test items, all of which need to be realized by contacting the tabs with equipment tooling, and these processes will inevitably affect the flatness of the tabs. The flatness of the tabs is very important for pack transfer welding. When the flatness of the tabs is too large, problems such as solder joints and welding explosions will occur during welding, which will directly lead to defective batteries. Especially for manufacturers with high quality requir...
