Problems solved by technology

Since the composition of the core pack is formed by stacking a certain length of diaphragm and multiple positive and negative plates according to a certain logical relationship, each stacking of the three (diaphragm, positive plate, and negative plate) is a lamination cycle, and Because a core package is composed of multiple pole pieces, each core package requires multiple lamination cycles, and each core package takes a lot of time to make, so that the core package making process becomes the entire process section. One of the bottlenecks in increasing production capacity
The existing stacking machine in stable production takes a long time to stack a single piece, and the stacking efficiency is not high
If the speed of lamination is increased, technical problems such as diaphragm loosening and tearing will be encountered, and the key point causing these problems is that the tension control of the diaphragm is not constant

Embodiment 1

[0024] A double swing arm type tension control device for folding the diaphragm 7, including a first swing arm mechanism 5 and a second swing arm mechanism 6, through which the first swing arm mechanism 5 and the second swing arm mechanism 6 swing to move the The diaphragm 7 is Z-guided and folded. When the first swing arm mechanism 5 guides the diaphragm 7 to one side, the second swing arm mechanism 6 tensions the diaphragm 7. When the second swing arm mechanism 6, when the diaphragm 7 is guided to the other side, the first swing arm mechanism 5 tensions the diaphragm 7.

[0025] The double-swing arm type tension control device of the present invention uses the first swing arm mechanism 5 and the second swing arm mechanism 6 to swing according to a certain logical relationship to carry out Z-shaped guiding and folding of the diaphragm 7. Specifically, when the first swing arm mechanism 5 When the diaphragm 7 is guided to one side, the second swing arm mechanism 6 tensions the...

Embodiment 2

[0036] A double-swing arm type lamination machine, comprising: a lamination table mechanism 1 for lamination, a diaphragm discharge mechanism 2 arranged above the lamination table mechanism 1, a diaphragm discharge mechanism arranged on the lamination table mechanism 1 and a diaphragm discharge mechanism 2, a double-swing arm tension control device, a first feeding device 3 provided on one side of the stacking table mechanism 1 for transporting the positive electrode sheet to the stacking table mechanism 1, and a part of the stacking table mechanism 1 The other side is used to convey the negative electrode sheet to the second feeding device 4 of the stacking platform mechanism 1; it includes a first swing arm mechanism 5 and a second swing arm mechanism 6, through which the first swing arm mechanism 5 and the second swing arm mechanism The second swing arm mechanism 6 swings to guide and fold the diaphragm 7 in a Z shape. When the first swing arm mechanism 5 guides the diaphrag...

Abstract

The invention relates to the technical field of tension control, in particular to a double-swing arm type tension control device and a double-swing arm type lamination machine, the double-swing arm type tension control device comprises a first swing arm mechanism and a second swing arm mechanism, the diaphragm is guided and folded in a Z form by swinging the first swing arm mechanism and the second swing arm mechanism, the second swing arm mechanism tensions the diaphragm when the first swing arm mechanism guides the diaphragm to one side, and the first swing arm mechanism tensions the diaphragm when the second swing arm mechanism guides the diaphragm to the other side. The diaphragm is carried out in the Z form by swinging the first swing arm mechanism and the second swing arm mechanism,specifically, when the first swing arm mechanism guides the diaphragm to one side, the second swing arm mechanism tensions the diaphragm, controls the tension of the diaphragm, and eliminates the problem of sudden change of the diaphragm length in the lamination process, thereby avoiding problems such as diaphragm loosening and tearing in the high-speed lamination process.

Description

technical field [0001] The invention relates to the technical field of tension control, in particular to a double swing arm tension control device and a double swing arm lamination machine. Background technique [0002] The manufacturing process of the pouch battery core pack is in the middle and front stage of the pouch battery manufacturing process, and it is an indispensable process in the pouch battery production. Since the composition of the core pack is formed by stacking a certain length of diaphragm and multiple positive and negative plates according to a certain logical relationship, each time the stacking of the three (diaphragm, positive plate, negative plate) is a lamination cycle, and Because a core package is composed of multiple pole pieces, each core package requires multiple lamination cycles, and each core package takes a lot of time to make, so that the core package making process becomes the entire process section. One of the bottlenecks in the increase ...
