Description

Technical Field

[0001] The present invention relates to the technical field of battery manufacturing, and in particular to an automatic feeding device for cylindrical soft-pack lithium batteries and a production line thereof. Background Art

[0002] Soft-pack lithium batteries usually refer to lithium batteries whose outer shells are encapsulated by aluminum-plastic composite films. Soft-pack lithium batteries are light in weight and highly safe. When safety hazards occur in soft-pack lithium batteries, since the outer shells are encapsulated by aluminum-plastic composite films, only bulging and rupture will occur, and no violent explosion will occur.

[0003] Soft-pack lithium batteries are battery cells wrapped with an aluminum-plastic composite packaging film, and then the electrolyte is injected into the mold cavity for packaging inspection. Existing soft-pack lithium batteries mainly use cylindrical cells and square cells. In the production process of existing soft-pack lithium batteries, multiple soft-pack batteries are linearly placed in parallel in the placement slot of the battery tray, and the battery tray is transported to the next inspection station and the edge sealing station. After the battery tray loaded with soft-pack batteries is close to the next station, the soft-pack batteries in the placement slot of the battery tray are taken out, and the batteries are placed flat on the inspection station and the edge sealing station. Most of the existing soft-pack lithium batteries are manually transported, which can easily cause the batteries in the tray to shake, and the soft-pack batteries need to be buckled out of the battery tray during the manual material removal process. Since the aluminum-plastic composite packaging film of the soft-pack battery is thin, manual material removal will cause the battery packaging film to rupture and be damaged during the battery removal process, and manual material removal leads to slow efficiency, and the accurate placement of each battery cannot be ensured during the manual placement process.

[0004] Although the existing soft-pack battery handling and loading device can realize automatic battery handling and loading, multiple cylindrical soft-pack lithium batteries are placed side by side inside the pallet, and the battery cells of the soft-pack lithium batteries are cylindrical, and the outer part of the battery is an arc surface. The battery cells of adjacent batteries are relatively close, which will cause jamming and collision deformation of two adjacent cylindrical soft-pack lithium batteries during the battery retrieval process, and the batteries cannot be used after retrieval. If multiple cylindrical soft-pack lithium batteries are retrieved one by one, the work efficiency will be affected.

[0005] With reference to the Chinese invention patent with patent application number "201410604420.0" and patent name "Soft-pack lithium battery formation loading and unloading device", the technical scheme discloses "a soft-pack lithium battery formation loading and unloading device, which includes a double manipulator, a positioning fixture, a shaping fixture, a flipping device, a first transfer manipulator, a lithium battery collection water truck, a transfer fixture, a double battery unloading mechanism and a second transfer manipulator; the double manipulator, the lithium battery collection water truck and the transfer fixture are arranged in an X direction and in front and back in sequence; the positioning fixture and the shaping fixture are located in front of the double manipulator; the first transfer manipulator is located in the The first transfer manipulator is located at the same end of the double manipulator and the lithium battery collection water truck and is arranged in the Y direction; the second transfer manipulator is located at the other end of the lithium battery collection water truck and is arranged in the Y direction; the flip device is located between the shaping fixture and one end of the first transfer manipulator; the double battery unloading mechanism is located between the transfer fixture and one end of the second transfer manipulator. "Although this technical solution can effectively realize automatic loading and unloading actions to improve work efficiency, this technical solution cannot solve the problem of adjacent batteries jamming and colliding due to the small gap between cylindrical soft-pack lithium batteries during batch loading and unloading of cylindrical soft-pack lithium batteries.
