Some embodiments of the invention are described in detail below with reference to the accompanying drawings. Features in the embodiments described below may be combined with each other without conflict.
At present, the winding of the battery core or the lamination of the battery core is an important process link in the production process of the lithium battery. The example of winding the battery cell is used for explaining, and the winding machine is a key device which influences various performance indexes of the lithium battery and is a decisive device which influences the production efficiency of the lithium battery. Since the production efficiency (winding speed) of the current winding machine is difficult to improve, the winding of the battery cell also becomes a limitation to the production efficiency of the lithium battery. The winding machine is used for winding four strips 200 (a positive plate, a negative plate and two diaphragms) together to form the battery cell, and tension control of the four strips 200 in the winding process determines the quality of the battery cell and influences the winding speed of the battery cell.
In particular, because the strip material 200 has a small thickness, a low elastic modulus, and is easy to deform, which makes it extremely difficult to control the tension, the strip material 200 is generally supported and guided by rollers, and the sliding friction between the rollers and the strip material 200 and the rotational inertia of the rollers have a great influence on the tension control of the winding machine.
Since the tension control of the soft strip 200 is a motion control system with a large time delay, the system is not constant but time-varying; the roll diameter is continuously changed due to the continuous consumption of the rolled strip material 200 along with the material; since the shape of the strip 200 is not fixed, the thickness distribution and the elastic modulus thereof are not equal everywhere; the tension system of the strip material 200 is made non-linear and not easy to observe, and therefore, the tension control of the strip material 200 is now based on traditional experience and no theoretical model has been established.
Thus, in a short working period (producing one cell), the strip 200 passes through a process of changing from static, accelerating to constant speed, and then from constant speed, decelerating to static speed in a large range, so that the precision of tension control cannot meet the requirements of product performance and quality. In order to ensure the product quality, only the winding speed can be reduced, which is a main reason that the production efficiency of the winding machine is difficult to improve. The scheme that the airflow suspension device 100 is used for suspending the strip 200 is provided, the strip 200 is prevented from contacting with the roller, the friction resistance of the strip 200 in the moving process is eliminated, the influence of the rotational inertia of the roller on the system tension is avoided, the problem that the production efficiency of a winding machine cannot be effectively improved on the premise of ensuring the product quality is solved, and the production efficiency of the lithium battery is improved.
First embodiment
Referring to fig. 1, fig. 2 and fig. 3 (arrows in fig. 3 indicate air flowing directions), the embodiment of the present invention provides a lithium battery production apparatus (not shown) for producing a lithium battery. The tension control device can avoid the influence on the tension of the strip material 200, simplify the tension control process, improve the tension control precision, shorten the tension control delay, accelerate the system response and improve the product quality.
In this embodiment, the lithium battery production equipment is a winding machine, the winding machine is used for winding four strips 200 (positive plate, negative plate and two diaphragms) to form a battery cell, the airflow suspension device 100 is applied in the winding machine, the airflow suspension device 100 is used for conveying the strips 200, but the invention is not limited thereto, and in other embodiments, the lithium battery production equipment may also be a lamination machine, the lamination machine is used for laminating four strips 200 (positive plate, negative plate and two diaphragms) to form a battery cell, and the type of the lithium battery production equipment is not particularly limited.
The airflow suspension device 100 includes a housing 110, a fan 120, and a controller (not shown). The fan 120 is fixedly installed in the housing 110, the housing 110 is provided with a through hole 111, and the fan 120 is used for blowing air out through the through hole 111 so as to suspend the strip 200 on the surface of the housing 110. Specifically, the fan 120 can blow out a stable air outlet flow outwards, and wind generated by the air outlet flow acts on the strip 200, so that the strip 200 is suspended, and the strip 200 can be supported and guided, compared with a scheme that the strip 200 is supported and guided by a roller in the prior art, the air flow suspension device 100 provided by the application can avoid the contact between the shell 110 and the strip 200, so that the influence of rotational inertia on the tension of the strip 200 is prevented, the friction coefficient between the strip 200 and the air outlet flow is extremely low, and the friction resistance generated between the strip 200 and the air outlet flow can be ignored, so that the influence of the friction resistance on the tension of the strip 200 is avoided, the tension control process is simplified, the tension control precision is improved, the tension control delay is shortened, the system response is accelerated, the product quality is improved, and the production efficiency of the battery cell is improved.
It should be noted that the controller is connected to the fan 120, and the controller is configured to adjust an air outlet amount of the fan 120 to adjust the tape running tension of the tape 200. Specifically, the controller can adjust the rotation speed of the fan 120, and the larger the rotation speed of the fan 120 is, the larger the air outlet volume is, the larger the acting force generated on the strip 200 is, so that the strip 200 is tensioned, and the tension of the strip 200 is increased; the smaller the rotation speed of the fan 120, the smaller the air outlet volume, the smaller the acting force generated on the strip 200, so that the strip 200 is loosened and the tension of the strip 200 is reduced. Therefore, the tension control process is simple, the tension control precision is high, the tension control delay is short, the system response is fast, and the production efficiency of the battery cell is high.
