Problems solved by technology

[0002] In film production, because the film itself has plastic deformation characteristics, the film surface changes rapidly with time, ambient temperature, winding tension, film thickness and other factors, which leads to a certain deviation between the actual flatness of the diaphragm and the required value , if it cannot be detected in time, the utilization rate of the diaphragm will be reduced
However, the detection of the flatness of the membrane surface is the biggest problem for enterprises. Generally, it is judged by human experience, and the situation of the membrane surface cannot be quantified and described.

Embodiment 1

[0016] In film production, the flatness of the membrane surface is generally judged by human experience, and the situation of the membrane surface cannot be quantified and described, resulting in a certain deviation between the actual flatness of the diaphragm and the required value, which reduces the utilization rate of the diaphragm. See figure 1 , for this reason, the present invention provides a kind of diaphragm flatness detection device, comprises: measuring frame 1, the multi-dimensional measuring assembly 2 that is installed on the measuring frame 1, the unwinding mechanism 3 that is installed on the measuring frame 1; The mechanism 3 is suitable for spreading the membrane 4 on the measuring frame 1 so as to detect the flatness of the spreading surface 41 of the membrane 4 through the multi-dimensional measuring assembly 2 .

[0017] The diaphragm flatness detection device of the present invention spreads the diaphragm on a measuring frame through an unwinding mechanis...

Embodiment 2

[0039] On the basis of embodiment 1, this embodiment 2 provides a working method of the diaphragm flatness detection device, that is, the diaphragm is spread by the unwinding mechanism, and then the flatness of the diaphragm spreading surface is detected by the multi-dimensional measuring component.

[0040] For the specific structure and implementation process of the detection device, refer to the relevant discussion of Embodiment 1, and details are not repeated here.

[0041] In summary, the diaphragm flatness detection device and its working method of the present invention measure the condition of the diaphragm at the set counterweight through the air-inflated unwinding reel, two parallel rollers, and a scale movable in the X / Y / Z three axes. The deformation difference value of the membrane surface (spreading surface) in the three axial directions can be used to judge the deformation of the membrane surface in the length direction, width direction and height direction. It has t...

Description

technical field [0001] The invention belongs to the technical field of lithium battery diaphragms, and in particular relates to a diaphragm flatness detection device and a working method thereof. Background technique [0002] In film production, because the film itself has plastic deformation characteristics, the film surface changes rapidly with time, ambient temperature, winding tension, film thickness and other factors, which leads to a certain deviation between the actual flatness of the diaphragm and the required value , if it cannot be detected in time, the utilization rate of the diaphragm will be reduced. However, the detection of the flatness of the membrane surface is the biggest problem for enterprises. Generally, it is judged by human experience, and the situation of the membrane surface cannot be quantified and described. Therefore, it is necessary to develop a diaphragm flatness detection device with simple structure, low cost and convenient use. Contents of...
