Problems solved by technology
refer to figure 1 , the solid line 1 is the scanning trajectory before the pole piece is coated, the dotted line 2 is the scanning trajectory obtained after the first coating of the pole piece, and the dotted line 3 is the scanning trajectory obtained by scanning the pole piece after the second coating, and now In the existing technology, the problem of synchronous scanning of each scanning frame is not considered, resulting in that the trajectory obtained by each scanning cannot be guaranteed to be consistent, and the positions of thickness detection are inconsistent, which leads to inaccurate coating amounts obtained by subsequent calculations

The invention discloses a lithium battery pole piece coating thickness detection device, system and method. The device includes a primary scanning frame and at least one coating detection scanning frame. The primary scanning frame is equipped with a first control device, a first scanning device and a second scanning frame. A speed detection device; a second control device, a second scanning device and a second speed detection device are installed on the coating detection scanning frame; the control device and the speed detection device are arranged on multiple scanning frames, and the signal interaction between the control devices As well as the speed measurement of the speed detection device, the initial scanning synchronization of multiple scanning devices is realized, and the scanning speed of the scanning device is controlled by the speed measurement of the speed detection device, so that the slope of the scanning trajectory is the same, so as to ensure the thickness information collected by each scanning to the greatest extent. The track of the same, to ensure the accuracy of the thickness information, thereby improving the accuracy of subsequent coating amount calculation.
Description
technical field [0001] The invention relates to the technical field of metering, in particular to a device, system and method for detecting coating thickness of lithium battery pole pieces. Background technique [0002] In the coating process of lithium battery pole pieces, it is often necessary to install a scanning device on the scanning frame to detect the coating thickness after each coating process. Patent document CN110108239B discloses a pole piece quality information acquisition method, system and equipment. The scanning device scans the target pole piece through the set scanning parameters to obtain scanning data. The scan data includes pole piece thickness data or pole piece weight data. The scanning device scans each pole piece in the form of flowing water. It scans from one side of the pole piece, and then returns to the other side. It scans repeatedly in this way, and extracts the corresponding scanning time by calculating the scanning time period. The data in ...
