Edge and chamfer accurate grinding device of cylindrical glass optical lenses and method thereof

Abstract

The invention belongs to an optical processing technology, and relates to an edge and chamfer accurate grinding device of cylindrical glass optical lenses and a method thereof. The method enables the cylindrical glass optical lenses and an accurate grinding disc to form a needed angle through a chamfer positioning tool. Under the effect of frictional force, the self rotation of the cylindrical glass optical lenses and the relative motion of the cylindrical glass optical lenses with respect to the accurate grinding disc are realized through the rotation of the accurate grinding disc and the oscillation of a swinging arm, so that the edge and chamfer accurate grinding effect of the cylindrical glass optical lenses is achieved. In order to improve the efficiency and the edge and chamfer consistency of the cylindrical glass optical lenses, a poking wheel structure is designed to accelerate the self rotation motion of the cylindrical glass optical lenses and to increase the contact force between the cylindrical glass optical lenses and a lens disc. The increment of the contact force can prominently improve the chamfer accurate grinding efficiency of the cylindrical glass optical lenses; and the smooth and uniform self rotation motion of the cylindrical glass optical lenses can guarantee the uniformity of edges and chamfers. The edge and chamfer accurate grinding device of the cylindrical glass optical lenses and the method thereof can realize the accurate grinding of the edges and the chamfers of the cylindrical glass optical lenses in large batches with automation.

Description

technical field [0001] The invention belongs to the optical processing technology, and relates to a device and method for chamfering and finely grinding the edge of a cylindrical glass lens. Background technique [0002] Cylindrical glass lenses are widely used in the modern optical industry and are in great demand. Due to the design requirements of the lens or the technical requirements in the processing process, the two circular edges of the cylindrical glass lens usually need to be finely ground and chamfered. The current fine-grinding and chamfering is to use a spherical bowl whose diameter matches the diameter of the lens section, and use manual or human-like robotic arms to perform fine-grinding and chamfering, such as figure 1 shown. Their common feature is that only one cylindrical lens can be processed at a time. During the processing, manual intervention may be required throughout the process, or the cylindrical glass lens needs to be loaded and unloaded frequent...

AI Technical Summary

Problems solved by technology

Their common feature is that only one cylindrical lens can be processed at a time. During the processing, manual intervention may be required throughout the process, or the cylindrical glass lens needs to be loaded and unloaded frequently, and because the chamfer usually has strict size requirements, it must be measured interspersed in the middle. This makes the processing efficiency low and the operation complicated
