A pneumatic surface density detection device disclosed by the present invention comprises a detection mechanism, an indexing transmission mechanism and a pneumatic driving mechanism, the detection mechanism comprises a detection part and a turntable, the turntable is rotatably installed on the detection part, the turntable is provided with a plurality of installation positions, and the installation positions are used for placing standard sheets; the pneumatic driving mechanism is connected with the turntable through the indexing transmission mechanism and drives the turntable to rotate intermittently through the indexing transmission mechanism. As the pneumatic driving mechanism is adopted as a driving source, the pneumatic structure is not interfered by the electromagnetic interference of a high-voltage power supply, and the output precision is higher; moreover, the pneumatic driving mechanism drives the turntable to rotate through the indexing transmission mechanism, and the transmission input end in the indexing transmission mechanism drives the transmission output end to rotate by the same preset angle every time the transmission input end rotates by one circle, so that the pneumatic driving mechanism can drive the turntable to rotate by the same angle every time; therefore, each measurement point of the standard sheet can be ensured to be on the same point, and the detection accuracy is ensured.
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...
