Abstract

The invention relates to an unwinding device and unwinding equipment. The unwinding device comprises an unwinding shaft, a docking assembly and a belt head traction assembly, wherein the unwinding shaft is used for mounting a material coil with a belt head and a belt tail; the docking assembly is arranged downstream of the unwinding shaft; the unwinding device is used for fixing the belt head through the docking assembly, and keeping the belt head in a to-be-docked state; the belt head traction assembly comprises a driving component and a traction component; the driving component is connectedwith the traction component, and can be used for driving the traction component to move between an unwinding position and a to-be-docked position along a predetermined track; the traction component isconnected with the belt head at the unwinding position; and the traction component is used for releasing the belt head at the to-be-docked position, and the docking assembly is used for fixing the released belt head. The unwinding device in the embodiment of the invention can replace manual work to finish belt receiving work at a large degree, so that the time consumed in the belt receiving procedure is shortened effectively, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of pole piece processing of secondary batteries, in particular to an unwinding device and unwinding equipment. Background technique [0002] With the rapid development of the lithium battery industry, the requirements for the production efficiency of batteries are getting higher and higher. The battery core is formed by winding pole pieces. In the power battery cell preparation process, it is necessary to unwind the pole piece material roll through the unwinding equipment to facilitate the corresponding processing of the pole piece by the downstream processing equipment. At present, after the unwinding of the previous roll is completed, the roll is changed manually, and at the same time, it is necessary to manually connect and fix the tape head of the next roll with the tail of the previous roll. However, due to the differences in the individual skills of employees, the traditional manual splicing takes a ...
