Embodiment Construction
[0019] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0020] The present invention firstly provides a diaphragm tension control method of a stacking machine, which includes the steps of: during the process of making the distance between the diaphragm feeding mechanism and the stacking table move relatively from large to small, the floating roller is driven by a driving device to move, Drive the movement of the diaphragm wound on the floating roller, so that the diaphragm between the diaphragm feeding mechanism and the stacking table is kept in a tensioned state, wherein there is a clamp between the line between the starting point and the end point of the floating roller movement and the horizontal plane horn.
[0021] refer to Figure 1 to Figure 3 , the present invention provides a diaphragm discharge and tension ...

The invention provides a laminating machine and a membrane tension control method therefor and a membrane emptying and tension control structure. The membrane tension control method comprises the steps as follows: in the process that a membrane emptying mechanism and a laminating table oppositely move to reduce the distance there-between, a floating roll is driven by a drive device to move; and a membrane wrapping around the floating roll is driven by the drive device to move, so that the membrane between the membrane emptying mechanism and the laminating table is kept in a tension state; and an included angle is formed between a connecting line between a motion starting point and an end point of the floating roll and the horizontal plane. Constant tension control on the membrane is achieved; the membrane is kept in the tension state; the wrinkling phenomenon of the membrane is effectively avoided; and the quality of a cell is improved.
Description
technical field [0001] The invention relates to the field of battery manufacturing equipment, in particular to a lamination machine and a diaphragm tension control method thereof, a diaphragm discharging and tension control structure, and is suitable for lamination of lithium batteries, nickel-hydrogen batteries, and nickel-chromium batteries. Background technique [0002] When stacking in the laminating machine, the positive and negative plates are stacked alternately. The diaphragm adopts Z-shaped feeding to separate the positive and negative plates. The diaphragm feeding mechanism and the stacking table will have relative displacement. The distance between them will vary from large to small. In this process, if the tension of the diaphragm is not controlled, it will cause the diaphragm to wrinkle. In the traditional stacking machine, the tension of the diaphragm is mainly controlled by the weight of the floating roller. The tension of the diaphragm cannot be kept constant...
