AI Technical Summary
Existing workpiece transfer and handling systems have failed to effectively adapt to the highly corrosive environment of hydrofluoric acid in large-diameter mega-acoustic wet etching processes, resulting in insufficient equipment stability and positioning accuracy, and failing to meet the complex motion requirements under multi-slot cascaded layouts.
The system employs a fluorine-coated guide rail and rolling guide rail structure, combined with a stainless steel cantilever robotic arm, to achieve corrosion resistance and high-precision transmission of hydrofluoric acid. The servo motor-driven gear rack and ball screw assembly ensures the system's stability and positioning accuracy under high load conditions.
This improved the system's corrosion resistance and service life in a hydrofluoric acid environment, ensured high-precision workpiece transfer and positioning, met the stringent requirements of mega-acoustic wet etching processes, reduced maintenance costs and frictional heat generation, and avoided the risk of workpiece shaking and falling.
