Metal materials such as copper and aluminum are inevitably used in the production and manufacturing process of a battery (such as a lithium battery), the metal materials are required to be rolled into foil with very thin thickness, then materials such as graphite, ternary lithium, lithium cobaltate, lithium iron phosphate and the like are respectively paved on the surface of the foil, and finally a positive electrode or a negative electrode sheet of the battery is formed; and finally, compounding and winding different types of positive and negative pole pieces, diaphragms and the like with certain lengths to form the core component of the battery. Because the specifications of the batteries are different, the initial specification (width) of the manufactured pole piece is not in accordance with the use requirement of the pole piece of the corresponding battery, and the pole piece can be subjected to corresponding die cutting during specific use; for example, 18650 cells, which represent cells 18MM in diameter and 65MM in length, typically result in die-cut pole pieces of between 56-58MM in width. In order to solve the technical problem, the adopted method is that a layer of alumina slurry is coated on a foil material where die cutting is needed, after the alumina slurry is solidified, the copper foil or the aluminum foil of the pole piece can be embrittled or hardened, and finally die cutting treatment is carried out, so that the length of burrs after the die cutting of the pole piece is reduced.
The coating device in the prior art mainly uses a coating roller to coat the alumina slurry in the corresponding area of the pole piece, however, the coating device in the prior art has the problem of relatively poor coating quality in the use process; specifically, the applicator roll is used by hollowing out the applicator roll, i.e., leaving only a roll surface or coating zone (which is convex with respect to the roll body) that is as wide as the area to be coated. Further, when the coating roller is used, the roller surface in the coating roller is immersed into a material pool positioned below the coating roller, the roller surface is adhered with slurry along with the rotation of the coating roller, then the scraper is used for scraping the excessive slurry, and finally the slurry on the roller surface is transferred or coated on the passing foil material under the cooperation of the gluing press roller. However, in the application device, since the application area of the application roller is immersed in the material pool during the use process, slurry can be attached to both sides of the application area, and further, as shown in fig. 5-7, under the centrifugal force generated by the rotation of the application roller, the slurry on both sides of the application area can move to the application area and accumulate, that is, the slurry can accumulate at both ends in the width direction of the application area; further, after the coating is completed, the two ends of the slurry layer on the foil in the width direction become thicker, which results in inconsistent dryness of the coated pole piece (the thick region of the slurry layer is not easy to dry), and the coating device has the problem of poor coating quality in the using process.
