Description

Technical Field

[0001] The invention relates to the field of lens processing, and in particular to a spherical surface grinding device and a grinding method thereof for self-focusing lens processing. Background Art

[0002] Self-focusing lens, also known as gradient refractive index lens, refers to a cylindrical optical lens whose refractive index distribution changes gradually along the radial direction. It has focusing and imaging functions.

[0003] For high-precision optical lenses, the properties of optical lenses are extremely high. Therefore, it is necessary to ensure that the lens surface has low defects, high finish, good surface shape, and low surface roughness during the processing. The classical processing method can perform fine polishing and trimming on the surface to achieve high-precision quality requirements. However, the general cycle is long, the machine tool speed is low, the pressure is low, the efficiency is low, it is time-consuming and labor-intensive, and it is suitable for single-piece, sample and small-batch research and production.

[0004] my country's patent publication number: CN105834859A; publication date: 2016.08.10 discloses an optical lens processing process, including the following steps:

[0005] S1. Cutting and rough grinding: Cut the raw materials into basic blocks, modify the thickness, and rough grind the blocks to form the outer circular contour of the lens.

[0006] S2, fine rolling of the outer circle: the lens material processed in S1 is further ground on the outer circle, and the outer diameter and tolerance of the lens are controlled within the range required by the lens drawing. Preferably, the fine rolling of the outer circle is performed by clamping the lens material on the workpiece shaft and rotating it at a constant speed, cutting with a diamond grinding wheel, and grinding the outer circle, so that the lens material completes the grinding and forming of the outer circle contour during the rotation process and reaches a certain roughness. Then, the milling machine mills the spherical radius of the lens, while controlling the surface shape and center thickness.

[0007] S3, precision grinding, referred to as fine grinding: grind the lens material processed in S2 to the designed thickness. For large-diameter optical lenses, it is generally necessary to control the thickness difference of the spherical radius. The thickness difference is controlled by an equal thickness seat equipped with a micrometer. The thickness difference is ground according to the drawing. The thickness can be measured with the equal thickness seat. The lens surface is modified by grinding. The thickness difference is generally controlled to be less than 0.005mm to ensure the optical eccentricity C value. The equal thickness seat is generally used to correct the curvature surface error of large-diameter lenses during the processing of large-diameter lenses, thereby ensuring their optical eccentricity, etc. This method is relatively complicated, and there is no corresponding equipment for processing.
