Abstract

The invention relates to the technical field of sampling equipment, in particular to a coating surface density sampler which comprises a workbench, a flattening mechanism and a sampling cutter, wherein the flattening mechanism comprises a bearing base and a pressing plate, the pressing plate has a sampling opening, the pressing plate presses downwards to flatten materials, and the flattened materials are exposed out of the sampling opening; the sampling cutter comprises a rack, a cutter handle and a cutter, the rack is provided with a supporting frame and a cutter handle driving part, and the output end of the cutter handle driving part is connected with the cutter handle; and the cutter handle has a cutter groove, and the cutter is arranged in the cutter groove in a sliding mode. Under the action of pressure, the materials are flattened, wrinkles are smoothed, samples are punched out from a sampling opening during sampling, the punched samples are high in size precision, small in burr, little in powder falling, good in quality and high in follow-up detection precision, the device can be further suitable for flattening the materials of different sizes, full-automatic punching is achieved, and the sizes and shapes of a plurality of samples are kept consistent, and the sample quality is good.

Description

technical field [0001] The invention relates to the technical field of sampling equipment, in particular to a coating surface density sampling machine. Background technique [0002] In the production of lithium-ion batteries, the consistency of the electrode sheets coated with battery slurry directly affects the electrochemical performance of the battery, especially the performance of battery cycle, internal resistance, and consistency. Therefore, in the production process of battery coated pole pieces, it is necessary to monitor the areal density of coated pole pieces at all times. However, the sampling equipment in the prior art cannot flatten the material, and the direct stamping of the wrinkled material will lead to uneven size of the punched sample, many burrs, serious powder drop, and low sample quality, which will affect the subsequent detection accuracy , unable to meet the needs of modern production. In addition, most of the sample cutting in the prior art require...
