Cylindrical lithium batteries need to be encapsulated during production and processing.

[0003] In the prior art, the invention patent with publication number CN112366330B discloses a cylindrical lithium battery capping packaging system, including a base, a first electric oil cylinder, a capping frame and a pressing roller, the bottom of the base is symmetrically rotatably connected with two groups of conveying rollers, the two groups of conveying rollers are connected with a conveyor belt, the outside of the conveyor belt is equidistantly installed with multiple groups of inserts, and the rear end of the base is fixedly connected with a top frame. In this cylindrical lithium battery capping packaging system, firstly, a fully automatic processing structure is adopted, which can realize the automatic conveying, capping and rolling packaging operations of cylindrical lithium batteries, improve the efficiency and convenience of cylindrical lithium battery capping packaging processing, so as to meet the actual processing and use of cylindrical lithium batteries, and secondly, a magnetic inner buckle clamping structure is adopted, which can clamp the cylindrical lithium battery delivered to the processing station before processing, reduce the force offset and shaking phenomenon during the processing of cylindrical lithium batteries, thereby improving the stability of cylindrical lithium battery processing.

[0004] The cylindrical lithium battery cap packaging system provided by the above patent can conveniently transport, cap and roll the lithium battery.

[0048] Working principle: When in use, the battery cover plate and the positive pole ear will be welded by welding equipment first. The welded battery and cap will be transported to the conveyor 4 on one side of the body 1 by the conveying mechanism. The conveyor 4 will drive the battery to move near the turntable 3. The clamping port 31 on the turntable 3 will drive the battery to move. When the battery moves to the bottom of the pressing drive assembly 7, the turntable 3 stops rotating. The lifting cylinder 9 will drive the lifting rod 6 and the pressing drive assembly 7 to press on the battery cap, so that the battery cap is smoothly connected to the battery cylindrical shell. At this time, the battery is between the adapter plate 161 and the pressing plate 72. At the same time, the pressing cylinder 8 drives the roller head 82 to press on the intersection of the battery cylindrical shell and the cap, and the third motor 71 will drive the pressing plate 72 and the battery to rotate. The roller head 82 will roll the intersection of the battery cylindrical shell and the cap, so that there will be no gap between the battery cylindrical shell and the cap, ensuring good sealing between the battery cylindrical shell and the cap. After that, the turntable 3 will continue to rotate, so that the turntable 3 drives the battery to move to the installation opening 15 on the other side of the body 1, and the battery is transported away from the conveyor 4 on the other side of the body 1.

[0049] To sum up, compared with the prior art, the present application uses a capping device to compress and fix the cap, and the capping device can drive the battery to rotate. At the same time, a clamping cylinder 8 is provided near the battery capping position, and the clamping cylinder 8 is against the side of the battery, and then the clamping drive assembly 7 drives the battery to rotate, so that the clamping cylinder 8 can roll the battery to ensure that there is no gap between the cylindrical shell of the battery and the cap, and ensure that there is a good sealing effect between the shell and the cap, so that the subsequent sealing process of the battery using the sealing equipment can be simpler and more convenient.
