Automatic coil material changing and connecting device and method

Abstract

The invention discloses an automatic coil material changing and connecting device and an automatic coil material changing and connecting method. The device comprises a primary loading mechanism, a standby loading mechanism, an aligning mechanism, a first adhesive sticking mechanism, a second adhesive sticking mechanism and a control mechanism, wherein the aligning mechanism comprises a first connecting part and a second connecting part, the first connecting part comprises a tail sucker, and the second connecting part comprises a head sucker; the head sucker sucks the head of a standby coil material in advance, and the tail sucker is used for sucking the tail part of a primary coil material under the control of the control mechanism when the primary coil material is used up; after the tail part of the primary coil material is sucked, the aligning mechanism aligns the tail part of the primary coil material and the head of the standby coil material; and under the control of the control mechanism, the first adhesive sticking mechanism and the second adhesive sticking mechanism stick adhesive tapes on two faces at the connecting part between the tail part of the primary coil material and the standby coil material. The device and the method can improve the connection rate greatly and avoid influencing the production state of normal products.

Description

technical field [0001] The invention relates to a coil material device, in particular to an automatic coil changing material receiving device and an automatic coil changing material receiving method. Background technique [0002] When coil materials are used to process products in battery, packaging and other industrial fields, after a group of coil materials are discharged, it is necessary to change the coils in time, and connect the tail of the previous group of coils with the head of the next group of coils to continue The production and receiving process not only need to save materials, be accurate and efficient, but also ensure the normal product production status as much as possible to avoid affecting product quality and accuracy due to refueling. [0003] For example, in the field of batteries, at present, during the winding process of the battery core, the following method is adopted to realize the material connection of the pole pieces: when one roll of pole pieces ...

AI Technical Summary

Problems solved by technology

[0004] This traditional method of manually changing rolls and splicing materials is not only inefficient, but also cannot maintain the tension state and position of the pole piece before refilling because the pole piece is in a free stretch state after shutdown, resulting in unstable cell size and winding tension. Therefore, it will have a certain impact on the normal production status of the product.
