[0038] The roller 3 is installed on the roller shaft 2, and the roller 3 can reciprocate and move horizontally along the axis of the roller shaft 2 and rotate around the shaft;

[0039] The roller moving assembly 5 is fixedly installed on the mounting base plate 1, the tab roller assembly is arranged on the roller moving assembly 5, and the roller moving assembly 5 is used to drive the tab roller assembly to move along the axis and the radial direction of the roller 3, and the tab roller assembly and the roller 3 jointly roll the tab on the tab.

[0040] When using the device, the tab is passed through the gap slot 11, the roller 3 is moved along the axis of the roller shaft 2, the position of the roller 3 is adjusted, so that the roller 3 is adjacent to the tab; the position of the tab roller assembly is adjusted along the axis of the roller 3 by the roller moving assembly 5, so that the tab roller assembly is also adjacent to the tab, and at this time the tab is located between the roller 3 and the roller moving assembly 5; the position of the tab roller assembly is adjusted along the radial direction of the roller 3 by the roller moving assembly 5, so that the tab is clamped between the roller 3 and the tab roller assembly, the roller 3 and the tab roller assembly rotate relatively while the tab is running, and jointly roll the tab, thereby improving the structural strength of the tab.

[0041] For different lengths of the pole piece, the roller 3 and the tab pressing roller assembly in the device can be moved, so the position of the two on the device can be adjusted according to the length of the pole piece; for different thicknesses of the pole piece, the distance between the roller 3 and the tab pressing roller assembly is adjustable; therefore, the tab reinforcing device in the application can be applied to reinforcing the strength of different tabs without repeatedly disassembling the device, which is beneficial to improving the processing efficiency and production speed.
