AI Technical Summary
Existing lens polishing fixtures suffer from insufficient positioning accuracy and difficulty in storing polishing fluid during shear-thickening polishing. Furthermore, the adjustment of the relative position between the polishing tool and the lens relies on manual experience, resulting in significant positioning errors.
The system employs components such as a three-jaw chuck, vacuum suction cup, photoelectric sensor, and thin-film pressure sensor. It achieves high-precision positioning of the lens through three-point positioning, vacuum adsorption, and photoelectric sensor detection. It also combines a liquid collection tank to store polishing liquid and uses a thin-film pressure sensor to adjust the position of the polishing tool.
This technology enables high-precision lens positioning and effective storage of polishing fluid, reducing positioning errors and improving the accuracy and efficiency of shear-thickening polishing.
