AI Technical Summary
Existing technologies struggle to achieve coating uniformity when the surface to be treated on a workpiece is a complex curved surface or has a changing shape. This is especially true in vacuum coating equipment, where the coating uniformity varies significantly between workpieces, and fixtures need to be redesigned to accommodate the shape changes.
The modular design of the coaxial multi-bevel gear set allows the large bevel gear to drive the rotation of multiple small bevel gears, and the rotation angle of the coating fixture is adjustable to meet the needs of coating complex curved surfaces.
It achieves uniformity in coating on complex curved workpieces, improves coating effect, operational stability and load uniformity, and reduces coating non-uniformity.
