Float disc feeding method for planar wafer optical parts

Abstract

The invention relates to the field of processing of planar wafer optical parts, in particular to a float disc feeding method for planar wafer optical parts. The float disc feeding method includes the steps: firstly, covering lens paper on adhesion surfaces of planar wafer optical parts to be processed, further smearing diluted shellac on the adhesion surfaces and drying the adhesion surfaces for standby application; secondly, uniformly smearing a layer of castor oil on an adhesion film, leading the surfaces, which are covered with the lens paper and dried for standby application, of the planar wafer optical parts to face the adhesion film, placing the surfaces on the adhesion film smeared with the castor oil, and reserving a gap between each two adjacent planar wafer optical parts; and finally, filling hot melt adhesive in the gaps among the planar wafer optical parts. The float disc feeding method has the advantages that deformation of surfaces of the planar wafer optical parts caused by cure shrinkage of the hot melt adhesive is prevented, consumption of the adhesive is reduced, the optical parts are firmly adhered, pressure on the parts is uniformly distributed effectively during processing, and breakage of the parts is avoided during processing.

Description

technical field [0001] The invention relates to the technical field of flat sheet optical parts processing, in particular to a float loading method for flat sheet optical parts. Background technique [0002] The entire manufacturing process of optical parts is a grinding process, which uses a special mechanical spindle to drive the corresponding grinding mold and the bonding mold that fixes the parts to be processed, and adds special abrasives to rotate the parts to be processed and drive the iron arm between the mold and the processed parts. The surface of the part is oscillated to complete the grinding and manufacturing of the entire flat sheet. [0003] If small and medium-sized planar thin optical parts are processed in a single piece, often because the size is too small, it is difficult to control the surface accuracy of the processed surface, and the processing efficiency is also very low. Therefore, for this kind of parts, the form of single-piece processing is often...

Problems solved by technology

At the same time, due to the rigid contact between the parts and the bonding mold, the pressure received during the processing is not uniform, and the parts are easily damaged and scrapped, resulting in material and labor losses.
