Detailed Description
As shown in fig. 1 to 4, the polishing device applied to the ultra-small lens comprises a polishing die 3, wherein a polyurethane polishing layer 2 for improving polishing efficiency is arranged on an arc-shaped surface of the polishing die 3, a cross through groove 22 for guiding flow is formed in the polyurethane polishing layer 2, and the end part of the polishing die 3 is connected with a polishing machine; the polyurethane polishing layer 2 is matched with the clamp 5 to clamp the lens 4 to polish the processing surface of the lens 4.
The polyurethane polishing layer 2 is specifically manufactured by the following steps: cutting a polyurethane sheet with a circular area larger than the arc area of the groove of the polishing die 3 by using scissors, forming 4 fan-shaped symmetrical grooves 21, pressing the polyurethane sheet into the groove of the polishing die 3 by using a pressing die 1, extruding the pressing die 1 and the polishing die 3 with moderate force until the polyurethane sheet is extruded into a shape which is matched with the curvature surface of the groove of the polishing die 3, taking out the polishing die 3, and keeping the polyurethane polishing layer 2 on the curvature surface of the convex pressing die 1 for standby; heating the polishing mould 3 to 400 ℃ by using an electromagnetic oven, quickly and uniformly coating a layer of polyurethane as an adhesive, pressing the polishing mould 3 coated with polyurethane and the polishing layer 2 on the surface of the pressing mould 1 to positive pressure, quickly cooling to normal temperature by using water, loosening the pressing mould 1 and the polishing mould 3 at the moment, and taking out the polishing mould 3 to carry out edge correction on the redundant polyurethane polishing layer 2; a cross-shaped through groove 22 is formed on the arc-shaped surface of the polishing layer 2 of the polishing mold 3 by a hot blade, the groove depth is 0.1mm when the groove contacts with the substrate of the polishing mold 3, and the thickness of the polyurethane polishing layer 2 is 0.3mm. The cross grooves 22 serve for drainage and diversion during polishing.
The working flow is as follows: the fixture 5 is heated, a layer of asphalt is coated on the groove surface of the fixture 5, and then the machining surface of the lens 4 is polished by matching with the polyurethane polishing layer 2 of the polishing mold 3 under normal pressure with the non-machining surface of the lens 4.
