Abstract: The present disclosure provides a conveying roller cleaning method, a conveying roller cleaning device, and a material tape conveying equipment. In the conveying roller cleaning method, the conveying roller is configured to convey a material tape, and the cleaning method includes: connecting a head end of an adhesive tape with a tail end of the material tape; and the material tape pulling the adhesive tape to move so as to make the adhesive tape pass through the conveying roller and remove impurities from a surface of the conveying roller. The conveying roller cleaning method can clean the conveying roller.

Abstract: A separation device is described. The separation device includes a rack, a turntable rotatably disposed on the rack; and at least one magnetic element disposed on the turntable. The turntable includes a top surface, and the magnetic element is recessed in or flush with the top surface. The separation device includes a separation membrane detachably disposed on the top surface. In some cases, the at least one magnetic element comprises a plurality of magnetic elements, and the plurality of magnetic elements are spaced apart along a circumferential direction of the turntable. The separation device and a material separation method disclosed are capable of reducing impurities in a slurry.

Abstract: A welding dust removal apparatus may include a dust removal pipe, one end of the dust removal pipe communicating with a suction apparatus; and dust suction assemblies, each including a first dust suction member and a second dust suction member, where the first dust suction member may have a first dust suction opening and a first outlet communicating with each other, the second dust suction member may have a second dust suction opening and a second outlet communicating with each other, an electrode assembly may be placed between the first dust suction opening and the second dust suction opening, and both the first outlet and the second outlet may communicate with the other end of the dust removal pipe.

Abstract: A tab cleaning apparatus is provided. The tab cleaning apparatus includes: cleaning assemblies, where the cleaning assembly is provided with an air channel inside, and the air channel is provided with an air inlet and an air outlet; and a suction assembly, where the suction assembly is connected to the cleaning assembly, the suction assembly is connected to the air outlet, the suction assembly operates to make air enter the cleaning assembly from the air inlet so as to form a negative pressure zone on the side of the air inlet, and a tab is placed in the negative pressure zone so as to clean the tab. The tab cleaning apparatus of this application can remove metal filings and other impurity particles at tabs, thereby improving the cleanliness of cells, reducing the self-discharge failure rate of cells, and improving the safety of cells.
