The invention discloses a pneumatic surface density detection device, which includes a detection mechanism, an indexing transmission mechanism and a pneumatic drive mechanism. The detection mechanism includes a detection component and a turntable. The turntable is rotatably installed on the detection component. , the installation position is used to place the standard sheet; the pneumatic drive mechanism is connected with the turntable through the index transmission mechanism, and the pneumatic drive mechanism drives the turntable to rotate intermittently through the index transmission mechanism. Since the pneumatic drive mechanism is used as the driving source, the pneumatic structure will not be subject to electromagnetic interference from the high-voltage power supply, and has higher output accuracy; moreover, the pneumatic drive mechanism drives the turntable to rotate through the indexing transmission mechanism, and the transmission input end of the indexing transmission mechanism Each rotation drives the transmission output end to rotate the same preset angle, so that the pneumatic drive mechanism can drive the turntable to rotate the same angle each time, thereby ensuring that each measurement point of the standard piece is at the same point, ensuring the accuracy of the detection accuracy.
Description
technical field [0001] The invention relates to the technical field of lithium battery detection, in particular to a pneumatic surface density detection device. Background technique [0002] The areal density of lithium battery pole pieces is closely related to the performance of lithium batteries. In the production process of lithium batteries, it is necessary to detect the areal density of pole pieces to judge the state of pole pieces. Therefore, the reliability of pole piece surface density detection equipment depends on appears extremely important. The measurement principle is that a certain amount of rays penetrate the pole piece, and the surface density of the pole piece is judged from the amount of loss after the rays penetrate the pole piece. Exciting rays require a high-voltage power supply, which may cause electromagnetic interference to surrounding electrical components. During the calibration and verification or verification process of the pole piece surface de...
