Lithium battery pole piece slitting corner burr detection device

Abstract

The invention discloses a lithium battery pole piece slitting corner burr detection device, and relates to the field of lithium battery detection. The lithium battery pole piece slitting corner burr detection device comprises a protection shell and a winding mechanism, the top end of the protection shell is provided with a control mechanism, and the control mechanism extends into the protection shell and is connected with a plurality of sets of single-chip microcomputers; a pushing air cylinder is installed on the inner wall of the control mechanism and located in the middle of the single-chip microcomputer, and the output end of the pushing air cylinder is connected with two sets of rotating air cylinders. Through arrangement of a rotating ring, blowing holes, an air suction fan, a second motor and second belts, when a pole piece is detected, the rotating ring and the air suction fan are driven to rotate through two groups of second belts, the rotating ring drives the multiple groups of blowing holes to rotate around a lens of a wide-angle camera, and the air suction fan sucks external air into a collection mechanism; the air flow passes through the guide ring and is discharged through the blowing holes, and the discharged air flow is blown to the inclined plane outside the lens and forms upward air flow along the inclined plane.

Description

technical field [0001] The invention relates to the field of lithium battery detection, in particular to a device for detecting burrs on cutting corners of pole pieces of lithium batteries. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and uses a non-aqueous electrolyte solution. Lithium batteries are usually composed of positive and negative pole pieces. When producing pole pieces, the battery slurry is usually uniformly Coated on the positive and negative current collectors, after evaporative drying of the pole piece, the pole piece needs to be cut to a suitable size by a cutting knife. After cutting, due to the unevenness of the blade and the shaking during the cutting process, the pole piece will Burrs are generated on the edge of the burrs. Generally, when the burrs are too long or too many, when the lithium battery pole piece with burrs is applied to the battery, i...
