Abstract: In a manufacturing process of a battery or a circuit board, or a printing process, there is a case where a long sheet material is conveyed from an unwinding unit to a winding unit. One object of the present disclosure is to provide a technique capable of preventing the long sheet material from being rubbed by a roller when the material is conveyed. The present disclosure relates to a conveyor adapted for a battery manufacturing process. The conveyor comprises a roller configured to convey a long sheet material, a shaft through the roller; a bearing installed between the roller and the shaft, and a driver configured to rotate the shaft in the same direction as a rotating direction of the roller conveying the long sheet material.

Abstract: A coating device includes a backup roll configured to transport a workpiece; a coating die configured to discharge a coating liquid onto the workpiece; a drive section capable configured to drive the backup roll; and a heat dissipation section configured to dissipate heat generated in the drive section.

Abstract: An apparatus for manufacturing an electrode body includes a coater and an attraction magnet. The coater applies a mixture paste including an electrode active material to a substrate that is configured to be a current collector. The attraction magnet is opposed to an applied layer of the mixture paste formed on the substrate so that when the mixture paste contains a metal object, the attraction magnet attracts the metal object so as to change a shape of a surface of the applied layer.

Abstract: A method for manufacturing a rechargeable battery includes a simultaneous coating process for simultaneously coating an electrode substrate with one strip of a mixture paste and two strips of an insulation paste dispensed from a dispenser so that each widthwise end of the strip of the mixture paste is adjacent to a different strip of the insulation paste. The simultaneous coating process includes a gap adjustment process for changing a distance between the dispenser and the electrode substrate based on a coating width of the mixture paste, detected in the simultaneous coating process by an image inspection unit, so that the coating width of the mixture paste approaches a target value.
