A lithium battery diaphragm casting thickness detection device

Abstract

The invention discloses a lithium battery diaphragm cast thickness detection device, which relates to the field of lithium battery diaphragm detection, including a mounting frame and a diaphragm, the mounting frame is arranged in a C shape, the mounting frame is located at the diaphragm, a mounting shell is welded to one side of the inner top of the mounting frame, a through groove is provided on the bottom wall of the mounting shell, three friction rollers are provided in the mounting shell, the three friction rollers are arranged in a triangle, the outer wall of one friction roller contacts the upper surface of the diaphragm through the through groove, the three friction rollers are covered with absorbent cloth, a cleaning shell is welded at the center line of the inner top of the mounting shell, strip-shaped through holes are provided on both side walls of the cleaning shell, the absorbent cloth passes through the cleaning shell through two through holes, a guide pipe is connected to the center of the bottom of the cleaning shell, the guide pipe passes through the mounting shell and the mounting frame in sequence and extends to the outside, the application can clean the moisture on the surface of the diaphragm during thickness detection, avoid moisture affecting the propagation speed and light intensity of the laser, and ensure the accuracy of detection.
