Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a novel pole piece connection platform. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Lithium batteries are generally used in conjunction with electrode sheets, and the electrode sheets must go through the process of pole winding replacement and tape splicing during production and processing. Currently, most of the mechanisms that perform this process on the market are ordinary tape splicing platforms, which are very likely to cause defects such as pole sheet wrinkling, tape breakage, serious deviation, and high amount of scrapped tail materials when the pole sheets are rewound and spliced. The above-mentioned defects are also the problems that technicians in this field need to solve urgently.

[0003] In order to solve the above technical problems, the currently used tape splicing device uses two pressure rods installed on a platform. The lower part of the pressure rod is controlled by a cylinder to lift and lower. One pressure rod presses one pole piece, and then the pole piece is held by hand to splice. In this tape splicing method, during the tape splicing process, the operator is very likely to put his hand under the pressure rod, and accidentally hurt his fingers during operation. At the same time, when the hand presses the pole piece, it will cause secondary pollution to the pole piece, and the dust generated during shearing will also pollute the space environment and increase the dust content in the space.
