Cutter driving apparatus and cutting device

A coating device for applying a coating to a member to be coated includes: a roller assembly including a first spool and second spool that are spaced apart, wherein the first spool is configured to release the member to be coated that is to be coated, and the second spool is configured to roll up the member to be coated after being coated with a coating; a coating assembly including an electrostatic roller set and an electrostatic rod, wherein the electrostatic roller set is at least partially rotatable and is configured to electrostatically adsorb the powder, the electrostatic rod is configured to provide electrostatic adsorption force to the powder on the electrostatic roller set; a composite assembly provided at downstream position of the coating assembly, and configured to connect the powder laid on the member to be coated with the member to be coated.

Coating device

A welding device may include a frame, a welding assembly, a fastening bracket, a protective pressure plate, a first drive mechanism, and a second drive mechanism; the welding assembly may include a first welding head and a second welding head that are arranged opposite each other, and the first welding head may be fastened on the frame; the fastening bracket may be movably provided on the frame, and the second welding head may be fastened on the fastening bracket; the protective pressure plate may be fastened on the fastening bracket or the second welding head; and the first drive mechanism may be drivingly connected to the fastening bracket and configured to drive the fastening bracket so that the second welding head may reach a position of a welding point and the protective pressure plate may press against a to-be-welded member.

Welding device and battery welding device

This application relates to a protective apparatus. The protective apparatus is configured to protect a to-be-welded part, the to-be-welded part includes a welding region, and the protective apparatus includes a base and a protective mechanism. The base is configured for embedding the to-be-welded part. The protective mechanism is connected to the base. The protective mechanism includes a welding hole, where the welding hole is provided corresponding to the welding region; and a surface of the protective mechanism facing the welding hole is provided with a thermally conductive coating, where the thermally conductive coating is configured to guide substances formed in welding the to-be-welded part to slide down along the surface of the thermally conductive coating. The protective apparatus in this application can improve welding quality of the welding region, thereby enhancing performance of the to-be-welded part.

Protective apparatus

Provided are a roller assembly, a battery cell manufacturing device, and an adjustment method of a roller, which relates to the field of battery manufacturing technology. The roller assembly includes a holder, a roller, and a first adjusting member. The roller is rotatably mounted on the holder. The first adjusting member is rotatably mounted on the holder, and one end of the roller is rotatably connected to the first adjusting member. A rotation axis of the roller does not coincide with a rotation axis of the first adjusting member. One end of the roller is rotatably mounted on the holder through the first adjusting member. The rotation axis of the first adjusting member does not coincide with the rotation axis of the roller, and therefore, rotation of the first adjusting member is capable of driving a corresponding end of the roller to rotate, thereby adjusting an extension direction of the roller.
