Oven temperature: room temperature--150℃ adjustable, temperature control accuracy <±5℃; Process flow The electrode sheet base material placed on the unwinding device enters the swing arm tension system after automatic deviation correction. After adjusting the unwinding tension, it enters the coating head, and the electrode slurry is coated according to the setting procedure of the coating system. The coated wet electrode sheet enters the oven for drying by hot air. The tension of the dried electrode sheet is adjusted by the tension system, and the winding speed is controlled at the same time, so that it is synchronized with the coating speed. The electrode sheet is automatically corrected by the correction system to keep it in the center position, and is wound by the winding device. Device 1. Unwinding mechanism (with automatic deviation correction device) The device is composed of servo unwinding, unwinding shaft with tension control, automatic deviation correction system, etc. The coil is pulled out and enters the swing arm tension device after automatic deviation correction. The device transmits the tension change during operation to the tension controller through the sensor, so as to achieve constant tension. 2. Swing arm tension mechanism The mechanism consists of rollers, position sensors, etc. The swing arm tension system absorbs the temporary changes in the storage space due to acceleration, deceleration, unwinding and starting the reel, and space fluctuations during the coating interval, so that the impact on the coating is minimized. The tension of the substrate is adjusted by the position of the swing arm, so that the substrate maintains a constant tension during the coating process, and the unwinding speed and the coating speed are controlled to keep synchronization. 3. Coating mechanism This machine is controlled by PLC and is equipped with high-tech automation equipment of precision machinery and opto-mechanical integration. It consists of extrusion die, coating roller, drive motor, optical fiber sensor, precision bearing and high-performance pneumatic components. Among them, the drive motor, reducer, pneumatic control, and the bearing of the coating roller are precision bearings. 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. For intermittent coating, the coating length and intermittent spacing of the first side and the back side can be set respectively, and two coating lengths can be set separately for each side. and intermittent distance to meet the special requirements of users. The set parameters can be continuously adjusted according to the specifications of the battery (single pulse) with a resolution accuracy of 0.01mm. After the back coating is automatically positioned by the optical fiber sensor tracking the first surface, the coating is carried out according to the parameters set on the back. Applicator roll and back roll speed indicators are set and displayed on the touch screen. 4. Drying system The drying system consists of heater, fan, exhaust duct and air hole, insulation box, inspection door, etc. The insulation box has a 1.0-meter section, a total of one section. The inner and outer parts of the box are made of stainless steel poles. The box body is a thermal insulation structure to prevent heat loss and safe operation. After the coated wet pole pieces enter the drying box, the box adopts the upper air drying method for efficient drying For drying, the dry air is sent by the fan to be heated by the hot air heater, and then sent to the inside of the oven, and is evenly blown to the wet coating by the air hole, and the dried air is discharged to the outdoors by the exhaust fan. 5. Take-up mechanism This device is composed of oven outlet, swing arm tension mechanism, belt drive device and winding tension sensor system. The tempo stays in sync. 6. Rewinding mechanism The device consists of a servo motor, a winding shaft, and an automatic deviation correction system. During the winding process, the device can make the winding shaft track the position of the pole piece, so that the edge of the winding pole piece can be kept neat. 7. Coating and drying automatic control system (1) Coating control system: This system consists of PLC, servo motor, touch screen and optical fiber sensor. As a human-machine interface, the touch screen has a friendly picture, intuitive display and convenient operation. During the coating process of this machine, the line speed of the coating roller, the coating speed and the number of coated sheets are automatically displayed on the touch screen, and the parameters set can be finely revised at any time according to the requirements of the production process.
