Benefits of technology
Problems solved by technology
The installation and replacement of the existing point inspection devices are relatively complicated, and the entire point inspection device needs to be replaced after the surface density measuring instrument is shut down. This calibration method causes production interruptions, which not only wastes manpower and material resources, but also affects normal production.

Abstract
The invention discloses a spot check device for an areal density gauge. The spot check device comprises a shell, a traversing mechanism, a locating component and a sample sheet mounting component, wherein the shell comprises a protecting cover and a fixing plate; the traversing mechanism comprises a linear guide rail component and a slide platform; the traversing mechanism is fixedly arranged in the protecting cover; the locating component comprises two limit switches and a sensing plate; one end of the sensing plate is fixedly arranged on the lower surface of the slide platform while the other end is corresponding to the limit switches; the sample sheet mounting component comprises a connecting plate and a sample sheet mounting plate. The invention also discloses a calibrating method of the spot check device for an areal density gauge. The calibrating method comprises the following steps: preparing coating sample sheets; weighting the coating sample sheets, thereby acquiring weight values; acquiring first LN values of each set of coating sample sheets; acquiring an average LN value of the first LN values of each set of coating sample sheets; linearly analyzing the average LN valueand the weight values, thereby acquiring an equation of linear regression curve and linear regression. The spot check device for the areal density gauge can be easily mounted and used and is high incalibrating precision.
Description
technical field [0001] The invention relates to the technical field of calibration of surface density measuring instruments, in particular to a point inspection device for surface density measuring instruments and a calibration method thereof. Background technique [0002] At present, during the coating process of lithiumion pole pieces, the thickness of the coating is detected online using a raymeasuring instrument, and its calibration is performed on-site. The known inspection device is an independent device, and its structure is composed of a whole set of systems. When calibrating, install the point inspection device on the surface density measuring instrument, and conduct repeated tests to determine the accurate result. When the surface density measuring instrument needs to be re-calibrated to measure different coatings, the point inspection device must be replaced. The installation and replacement of the existing point inspection devices are relatively complicated, a...
