Technical Field

[0001] The utility model relates to the technical field of battery diaphragms, and specifically relates to a detection device for battery diaphragms. Background Technique

[0002] In the structure of a battery, the diaphragm is one of the key inner components. The performance of the diaphragm determines the interface structure, internal resistance, etc. of the battery, and directly affects the characteristics such as the capacity, cycle, and safety performance of the battery. A diaphragm with excellent performance plays an important role in improving the comprehensive performance of the battery. During production, the thickness of the battery diaphragm will be detected to ensure that the produced battery diaphragm meets the requirements;

[0003] After retrieval, in the application document with the patent application number 202222437879.9, a thickness detection device for a battery diaphragm is disclosed, which includes a frame and a cabinet door. A cabinet door is arranged on the front surface of the frame. Side plates are arranged on the upper surfaces of the left and right ends of the frame. A turning handle is arranged on the outer surface of the side plate. The inner side of the turning handle is connected to the top right end of a threaded rod. The threaded rod is located inside the side plates. A slider is sleeved on the outer side of the middle of the threaded rod. The two sides inside the slider are connected to a limiting rod. A support frame is arranged on the upper end of the rear side of the frame. A linear motor is arranged on the left side of the upper surface of the support frame. A hydraulic cylinder is connected to the right surface of the linear motor. A hydraulic rod is arranged at the lower end of the hydraulic cylinder. A chute is opened at the connection between the hydraulic rod and the upper surface of the support frame. An indicating meter is arranged at the lower part of the hydraulic rod. The hydraulic rod and the indicating meter are connected to each other through a connecting plate. A laser probe is arranged at the bottom of the lower end of the indicating meter. This thickness detection device for a battery diaphragm can reduce the detection error with a mechanized detection method;

[0004] The above application document realizes the detection of the diaphragm thickness through the setting of the laser probe. However, how the laser probe detects is not disclosed, and since the diaphragm thickness is relatively thin, how the laser probe detects and how to ensure the detection accuracy have become problems to be solved urgently.

[0005] Therefore, we propose a detection device for battery diaphragms. Content of the Utility Model
