Problems solved by technology

[0004] 1. Due to the constant change of the tension of the diaphragm, the produced cells are constantly pulled by the changing force, and the accuracy is difficult to guarantee
[0005] 2. The production efficiency is very low. Due to the influence of the changing force on the properties of the diaphragm, the speed of the lamination cannot be increased.

Abstract

The invention provides a constant tension diaphragm discharging device for a lamination stacking machine. The discharging device comprises an unreeling mechanism which is installed with a reeled diaphragm, a diaphragm laminating mechanism for folding and putting a diaphragm, a collecting and discharging connecting rod mechanism which is linked with the diaphragm laminating mechanism and keeps the diaphragm buffer length and a tension control mechanism which provides the diaphragm discharging tension. The tension control mechanism comprises a diaphragm fixing roll for guiding the diaphragm, a diaphragm floating roll for regulating the diaphragm buffer length, a sliding guide rail for installing the floating roll, a tension controller which pushes the floating roll to slide so as to change the buffer length and a position sensor for detecting the position information of the floating roll. The diaphragm laminating mechanism comprises a sliding roller group which drives the diaphragm to be discharged and a horizontal sliding rail for installing the sliding roller group. The collecting and discharging connecting rod mechanism comprises a collecting and discharging roller which is controlled by the diaphragm laminating mechanism, a vertical sliding rail for installing the collecting and discharging roller and a collecting and discharging connecting rod which connects the collecting and discharging roller with the sliding roller group. The discharging device has the advantages that the collecting and discharging connecting rod is matched with the tension control mechanism, so that the constant tension control of the diaphragm is realized.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing equipment, in particular to the technical field of battery cell manufacturing, and in particular to a device for discharging diaphragms of a cell stacking station of a lamination machine. Background technique [0002] In the stacking machine of the prior art, the tension of the diaphragm is in an uncontrolled state when the cell diaphragm is discharged. [0003] The disadvantages of the prior art stacking machine for producing electric cores are as follows. [0004] 1. Due to the constant change of the tension of the diaphragm, the produced cells are constantly pulled by the changing force, and the accuracy is difficult to guarantee. [0005] 2. The production efficiency is very low. Due to the influence of the changing force on the properties of the diaphragm, the speed of the lamination cannot be increased. Contents of the invention [0006] The technical problem to be solved b...
