    Machine Vision Technology

    We use CMOS or CCD real-time image sensing and image acquisition technology to detect defects, alignment, width, etc. in the coating, slitting, winding and other sections of the lithium battery electrode production process, analyze the color, texture, shape and other features in the image to determine whether the product is qualified, and issue alarms in time or automatically adjust parameters of production equipment to achieve overall quality control and optimization.

    Automatic Correction Control Technology

    With sensor technology and servo control technology, deviations in the coating process can be monitored and adjusted in real time to ensure good coating quality and high production efficiency. The principle is to collect data from sensors, calculate the deviation, and adjust the operating parameters of the coating machine on the control device to achieve automatic correction. It performs closed-loop control by using CCD technology together for pre-correction to ensure the two sides alignment of ±0.2mm.

Innovative Drying Technology

    Infrared Heating

    The infrared hot air drying system uses hot air convection circulation to dry. While blowing away the air film on the surface of the electrode, it evenly transfers heat to various positions of the electrode, discharges high-concentration exhaust gas in time and replenishes fresh drying hot air. Hot air can greatly increase the evaporation and discharge rate of the solvent, reduce the mass transfer resistance, and improve the drying quality of the electrode. Infrared technology can be easily matched with existing production lines or partial transformation can be made on existing coating machines to achieve production goals.

    Laser Heating

    Infrared laser heating technology can slow down the temperature gradient in the depth direction, shorten the action time of capillary effect, fully alleviate the floating of binder, and delay the film formation time,and effectively avoid overheating of the dried area, weaken the capillary effect, and effectively increase void content. During the production process, gentle temperature gradient control is achieved, thereby reducing internal stress and effectively reducing the risk of electrode cracking.

    Electromagnetic Heating

    The high-frequency induced eddy current thermal effect is used to heat the foil. The foil transfers heat to the slurry through thermal conduction. The heating thermal resistance is small, the thermal gradient and the water vapor concentration gradient are in the same direction, and the drying efficiency is high.
