Description
Technical Field
The utility model relates to the technical field of lithium batteries, in particular to a film coiled material tension swing roller mechanism.
Background
In the production process of lithium batteries, a metal foil is generally selected as a current collector, wherein an aluminum foil is selected as a positive current collector, and a copper foil is selected as a negative current collector. In order to improve the energy density and safety of a battery, a composite current collector obtained by compositing a polymer film and a metal plating layer is attracting attention. However, since the composite current collector includes an insulating layer formed of a polymer material, the tab of the composite current collector cannot transmit the current in the cell to the electrode terminal, and thus it is necessary to transfer the tab of the composite current collector with a foil (aluminum foil or copper foil) so as to transmit the current in the cell.
The Chinese patent with publication number CN218732334U discloses a composite current collector transfer welding integrated device, which comprises a composite current collector unreeling frame for unreeling the composite current collector; the first foil unreeling frame is used for unreeling the first foil; the second foil unreeling frame is used for unreeling the second foil; the welding mechanism is used for welding the first foil and the second foil on two sides of the composite current collector to form a product; the rolling frame is used for rolling the product; the first foil tension swing roller is positioned between the first foil unreeling frame and the traction counter roller; the second foil tension swing roller is positioned between the second foil unreeling frame and the traction counter roller; and the current collector tension swing roller is positioned between the composite current collector unreeling frame and the composite current collector deviation correcting. The transfer welding integrated device for the composite current collector realizes continuous welding production of the composite current collector, and prevents wrinkling by adjusting the tension of a travelling belt through the tension swing roller.
However, the tension swing roller of the composite current collector transfer welding integrated device uses the cylinder drive to control the tension, and in the process of driving the swing roller by the cylinder, the response speed of the cylinder drive is relatively slow, so that the change of the tension cannot be tracked in time, the tension fluctuation is large, and the product quality and the production efficiency are affected. In addition, the feedback regulation response speed of the cylinder drive is not equal to that of the motor drive, so that the tension control precision is poor. Because the response speed is slower and the feedback adjustment precision is poorer, the response speed of tension control is also relatively slower, so that in the production process, when tension changes, the tension swing roller needs longer time to adapt to a new tension value, and the production efficiency and the product quality are further influenced.
The above drawbacks are to be ameliorated.
