The electrode substrate placed on the unwinding device is automatically rectified and then enters the swing arm tension system. After adjusting the unwinding tension, it enters the coating head, and the electrode slurry is coated according to the setting program of the coating system. The coated wet electrode enters the oven to be dried by hot air. After drying, the tension of the electrode is adjusted by the tension system, while the winding speed is controlled to synchronize it with the coating speed. The electrode is automatically corrected by the correction system to keep it in the center position, and the winding device is used for winding.
1.Unwinding structure (With automatic deviation correction structure)
This device is composed of servo unwinding, unwinding shaft with tension control, automatic correction system, etc. The coil is pulled out and enters the swing arm tension device after automatic correction. The device transfers the tension change during operation to the tension controller through the sensor, so as to achieve constant tension.
2. Coated floating roller tension structure
This mechanism is composed of rollers, position sensors, etc. The swing arm tension system absorbs the instantaneous changes in the storage space due to acceleration, deceleration, unwinding and start-up of the reel, and space fluctuations during the intermittent coating period, so as to minimize the impact on coating. The tension of the substrate is adjusted by the swing arm position, so that the substrate maintains a constant tension during the coating process, and the unwinding speed and the coating speed are controlled to be synchronized.
3.Coating structure
This machine is controlled by PLC and equipped with high-tech automation equipment of precision machinery and optical-mechanical-electrical integration. Slot die head, coating roller, drive motor, optical fiber sensor, precision bearing and high-performance pneumatic components. Among them, the drive motor, reducer, pneumatic control, the bearing of the coating roller adopts precision bearing, the man-machine interface, PLC, etc. constitute an intermittent coating system, and the coating program is designed according to the user's process size.
The coating method has two working modes: continuous coating and intermittent coating. Intermittent coating can separately set the coating length of the first side and the back side, and the intermittent interval. Each side can be set to two separate coating lengths. And intermittent distance in order to meet the special requirements of users. The set parameters can be continuously adjusted according to the battery specifications (single pulse) and the resolution accuracy is 0.01mm. After the back coating is automatically positioned by the optical fiber sensor to track the first side, the coating is carried out according to the parameters set on the back. The indexes of coating roller and back roller speed are set and displayed on the touch screen.
4.Dry System
The drying system is composed of heaters, fans, exhaust ducts and vents, insulation boxes, inspection doors, etc. The insulation box has a section of 1.2 meters in total. The inner and outer parts of the box are made of stainless steel. The box is a thermal insulation structure to prevent heat loss and safe operation. After the coated wet electrode enter the drying box, the box adopts the upper air drying method for high efficiency After drying, the dry air is heated by a fan and heated by a hot air heater, and then sent into the box, and blown evenly to the wet coating through the air holes, and the dried air is discharged to the outdoors by the exhaust fan.
5.Take-up structure
This device is composed of oven outlet, float roller tension mechanism, take-up drive device and take-up tension sensor system, etc., so that the pole piece maintains constant tension during coating (intermittent coating) and drying process, and controls the winding speed and coating The speed stays in sync.
6.Winding structure
This device is composed of servo motor, winding shaft, automatic correction system, etc. During the winding process, the device can make the winding shaft track the position of the electrode and keep the edges of the winding electrode neat.
