When pole piece, which is in, to be unreeled, pole piece sequentially passes through the first fixed idler whell 27 and the first tension oscillating arm mechanisms 29
Two the first action rollers 291.Wherein, the working principle of the first tension oscillating arm mechanisms 29 is: since the pulling tension of pole piece makes
First swing arm 292 is up put, and the first cylinder 293 is connect with the first swing arm 292 and certain permanent pulling force is generated to it, is at this moment made
First swing arm 292 is in a stress relative balance state.When the tension that pole piece is subject to changes, the first swing arm 292
Equilibrium state is broken, and the first swing arm 292 just can rotate, and the first angle measuring instrument 294 connecting with the first swing arm 292 can basis
The case where variation of its rotational angle, to control the direction of speed or rotation that pole piece unreels to make the first swing arm 292
Stress keeps opposite balance, to guarantee that the pole piece tension of transmission is constant.For example, when overtension, 292 meeting of the first swing arm
Pendulum upwards, pole piece accelerate the speed that unreels to reduce tension, on the contrary then reduce the speed that unreels to increase tension.Even, if
Part occurs for pole piece, and in tension-free situation, after the pole piece of part is connected again, pole piece unreeling structure 23 can be anti-
Receipts pole piece is gone back to, the tension situation of pole piece is adjusted, until first angle measuring instrument 294 detects that the first swing arm 292 restores again
Until stress balance, so that film-making can work on.
When pole piece is in winding, pole piece sequentially passes through the second fixed idler whell 28 and the second tension oscillating arm mechanisms 30
Two the second action rollers 301.Wherein, the work of the working principle of the second tension oscillating arm mechanisms 30 and the first tension oscillating arm mechanisms 29
It is identical to make principle, those skilled in the art can according to embodiments of the present invention and attached drawing, obtain corresponding technical solution, herein not
It repeats one by one.
If battery film-making winding device 100 is not provided with tension oscillating arm mechanisms, or only in the position setting unreeled
Power oscillating arm mechanisms, or tension oscillating arm mechanisms only are set in the position of winding, the stability that can all transmit to pole piece is inadequate, directly
Influence the slice-making quality of pole piece.Technical solution of the present invention, by unreeling and winding in battery film-making winding device 100
Position the first tension oscillating arm mechanisms 29 and the second tension oscillating arm mechanisms 30 are all set.First tension oscillating arm mechanisms 29 and second
Power oscillating arm mechanisms 30 can simultaneously to pole piece generation act on, so in time adjustment pole piece unreel with tension in wrapup procedure,
To control the speed and rotation direction that pole piece is unreeled and wound, effectively guarantees stability in pole piece transmission process, make tab
Welding mechanism 24 can be welded to positive and negative tab on the exact position of pole piece, to improve battery slice-making quality, Jin Erti
The service performance of high equipment.
As shown in Figure 1 to Figure 3, in an embodiment, battery film-making winding device 100 further includes deviation correction mechanism 37.Rectification machine
