Description

Four-axis rotation winding mechanism

Technical Field

The utility model relates to the technical field of lithium battery production processes, in particular to a four-shaft rotary winding mechanism.

Background

With the increasing explosion of new energy industry, the market has more and more strict requirements on new energy, high efficiency and stability are the most basic requirements of new energy equipment, and the quality becomes a new hard requirement for the competition of the battery industry. How to improve the quality: on one hand, starting from the source of the battery powder, the formula of the product is changed; on the other hand, starting from the production or manufacturing process of the battery, the process quality monitoring of the product is improved. For battery equipment, quality control and process monitoring are increased, corresponding monitoring sensors are required to be installed on the equipment, and therefore the length of the whole equipment production line is increased.

The length of the production line is increased, which means that the number of the produced products is reduced in a unit area factory building, so that the area of the factory building is increased, and the waste of land is caused. At present, in order to shorten the length of a production line, battery manufacturers often adopt a structure that two independent processes are combined into one process for production, so that products output from a first process to products input from a second process can be shared.

At present, the battery industry is advancing from GWh to TWh times, how to more effectively utilize the existing resources, and how to compress the length of a production line to a greater extent under the condition of unchanged functions becomes a technical problem to be solved which is forced to be at the top of the eyebrow.

SUMMERY OF THE UTILITY MODEL

In view of this, the present invention provides a four-axis rotary winding mechanism. The length of producing the line is shortened greatly in the use of this mechanism, has improved the factory building utilization ratio.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:

a four-shaft rotary winding mechanism comprises a frame, a rotary table and a driving motor for driving the rotary table to rotate; the device is characterized by also comprising n pairs of winding shafts, wherein n is more than or equal to 2; an upper roller and a lower roller are arranged on the frame; the rotary table is positioned between the upper roller and the lower roller; each pair of winding shafts are erected on the turntable and are symmetrical about the center of the turntable, and the upper roller and the lower roller are parallel to the winding shafts; each winding shaft is driven to rotate by a corresponding servo motor.

Further, n is 2.

Further, still include the automatic tape splicing system that changes of battery sheet, the automatic tape splicing system that changes of battery sheet is used for changing the area to the rolling axle and splicing.

The utility model adopts the technical scheme to produce the beneficial effects that:

the utility model respectively fixes the winding shafts 1, 2, 3 and 4 on the turntables. Two rolls of battery material are rolled up and are arranged on a big centre of gyration jointly, and rolling axle 1 and axle 3 are a set of rolling, and rolling axle 2 and axle 4 are a set of rolling, and every group rolling is each other not influence, when needs realize automatic splicing, can rotate turret mechanism, makes the material roll enter into automatic splicing fixed position, realizes the automatic splicing and trades the non-stop operation of rolling up, improves production efficiency and space utilization.

Drawings

Fig. 1 is a schematic diagram of the working state of the embodiment of the present invention.

FIG. 2 is a schematic diagram of a roll change in an embodiment of the utility model.

In the figure: 1. the device comprises an upper roller, a lower roller, a rotating central shaft, a rotating disc, a winding shaft, an upper belt receiving mechanism, a lower belt receiving mechanism, a winding shaft and a dividing cutter assembly.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Further, n is 2.

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without creative efforts.

Referring to fig. 1, a turntable 4 rotates about a rotation center shaft 3; after the battery pole pieces pass through the slitting knife assembly 11, one battery pole piece is cut into two or more strips, so that the quality of the battery is influenced by mutual abrasion after the contact of the notches, and the slit pole pieces need to walk in a staggered mode. I.e. a total of four cuts are made, a first and a third upper (or lower) run and a second and a fourth lower (or upper) run. The upper tape-feeding pole piece is wound by a winding shaft 5 after passing through an upper roller 1; the lower tape-feeding pole piece passes through the lower roller 2 and then is wound by the winding shaft 7. The winding shaft 6 and the winding shaft 8 are material waiting areas, and when the winding shaft 5 and the winding shaft 7 are fully wound, the next action is executed.

Referring to fig. 2, at this time, the takeup reel 5 and the takeup reel 7 are fully wound, and a reel change operation needs to be performed. After the turret rotates 90 degrees anticlockwise, the uppermost end is a winding shaft 8, the lowermost end is a winding shaft 6, the two shafts are provided with empty charging barrels, and the pole pieces are respectively fixed on the upper winding shaft and the lower winding shaft through an upper tape connecting mechanism 9 and a lower tape connecting mechanism 10. Thereby completing the automatic roll changing function of the battery pole piece.

The upper tape splicing mechanism 9 and the lower tape splicing mechanism 10 belong to a part of an automatic battery pole piece reel changing and splicing system, and the automatic battery pole piece reel changing and splicing system is the prior art and is not described herein again.
