Description

Technical Field

[0001] The utility model relates to the technical field of lens grinding equipment, in particular to a batch grinding jig for multiple concave optical lenses. Background Art

[0002] The multi-lens grinding jig is an auxiliary equipment for grinding the outer surface of the lens in the heat treatment process of the single crystal silicon polishing wafer. Through the use of the multi-lens grinding jig, the grinding work of the lens is facilitated, the synchronous grinding of multiple lenses is achieved, the efficiency of the lens grinding work is improved, and the heat treatment step of the single crystal silicon polishing wafer is accelerated.

[0003] After searching, it was found that the publication number is CN210189468U, and the name is multi-lens grinding jig. The application proposes that the current multi-lens grinding jig is inconvenient to position the lens. After the lens is installed, it is easy to cause displacement due to vibration during the lens grinding process, which increases the number of lens grinding steps and reduces the speed and work efficiency of lens grinding. Through the installation of the positioning rubber and its own specific structure, the lens is more stable when installed between the positioning rubbers, and will not loosen due to vibration during the lens grinding process, making the lens grinding work more stable and fast. However, when using this application, the staff needs to press the lens into the positioning rubbers and pick out the lens when taking it out, which makes installation and taking more trouble. At the same time, the fit between the positioning rubber and the lens is not high, and there is uncertainty when the reed is deformed, resulting in the grinding head squeezing the lens during the grinding process, and the lens squeezing the reed, causing the reed to deform, and ultimately causing the lens to shift. The problem is not stable and reliable enough, and further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
