AI Technical Summary

Technical Problem

Existing coating head adjustment devices struggle to achieve high degrees of freedom and stable adjustment on large-size substrates, resulting in insufficient coating accuracy and efficiency.

Method used

A coating head adjustment device was designed, including a crossbeam, a drive assembly, a rotating component, and an adjustment section. A servo motor drives a sliding frame and a linear motor to achieve two-axis, three-degree-of-freedom adjustment. Combined with an air-bearing slider and a guide rail structure, the reliability and accuracy of the adjustment are improved.

Benefits of technology

It achieves high-precision adjustment of the coating head for large-size substrates, improving coating efficiency and effect, especially the stability and control precision of the long-lip coating head.
