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

Provided are a cutting device, a cutting method, and a cutting apparatus. The cutting device includes a base; a pair of cutting blades, mounted to the base; a drive mechanism, configured to drive the pair of cutting blades to close or open to each other in a first direction; and an adjusting mechanism, configured to drive at least a portion of the base to undergo elastic deformation in a second direction before or during an opening process of the pair of cutting blades driven by the drive mechanism, so as to form a clearance between the pair of cutting blades in the second direction, wherein the second direction is a movement direction of a cutting material and intersects with the first direction.

Cutting device, cutting method, and cutting apparatus

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.

Roller assembly, battery cell manufacturing device, and adjustment method of roller

This application relates to a fixed blade monitoring structure and a cutting device used for lithium battery manufacturing. The fixed blade monitoring structure includes: an anvil, fixed blade die set, and a fixed blade monitoring assembly. A sliding sleeve is disposed on the anvil. The fixed blade die set includes a fixed blade holder and a fixed blade mounted on the fixed blade holder. An end of the fixed blade holder is slidably mounted in the sliding sleeve. The fixed blade monitoring assembly is mounted in the sliding sleeve and connected to the fixed blade holder, and configured to render status of the fixed blade by monitoring a relative force received by the fixed blade holder. Through the above structure, manpower and time consumption in the tuning process is reduced. The status monitoring of a first cutter and a second cutter can be implemented during the cutting.
