AI Technical Summary

Technical Problem

Traditional polyimide film production equipment has problems such as film rupture during high-temperature cycle, dust caused by friction, affecting film performance, chain jitter and tremor reducing quality, and lateral temperature difference leading to chromatic aberration.

Method used

The dual-track dust-free and oil-free imine furnace is designed. The inner and outer rails are connected by circulating conveying chains. The membrane contacts the rails through rolling bearings. The main transmission auxiliary transmission device is driven by the sprocket and reducer, which increases the infrared ceramic heating plate to adjust the temperature.

Benefits of technology

Through dual-track design and rolling bearings, the main transmission auxiliary transmission reduces chain shaking, and the infrared ceramic heating plate adjusts the temperature, solving the problems of film rupture, dust influence, jitter and chromatic aberration, and improving the yield and performance of the film.
