Lens grinding device for myopia correction glasses

Abstract

The invention discloses a lens grinding device for myopia correction glasses in the technical field of grinding devices.The lens grinding device comprises a base, a grinding unit, a fixing base, a communicating pipe, a suction head, a communicating cavity, an air hole, a sliding plug, an air groove, a driving unit, a fixing rod and pressing arms, wherein the suction head is connected with the pressing arm through a hinge unit, and when the suction head moves downwards, the two pressing arms swing towards the inner side of the suction head. The lens is placed on the top face of the suction head, the sliding plug is driven by the driving unit to move downwards, then air in the communication cavity enters the fixing base, negative pressure suction of the suction head on the lens is achieved, in addition, when the suction head moves downwards, the two pressing arms are driven by the hinge unit to swing relatively, the lens is clamped, in the way, negative pressure suction can be conducted on the lens, mechanical clamping can also be conducted on the lens, the lens can be in a stable state in the polishing process, manual operation is not needed, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of grinding devices, in particular to a lens grinding device for myopia correction glasses. Background technique [0002] The lens of myopia correction glasses is a relatively precise optical device. During processing, it is necessary to use grinding equipment to polish the outer arc surface of the lens. [0003] After retrieval, Chinese Patent No. CN213498247U discloses a constant temperature lens grinding system, including a grinder body, which includes a lens holding device for holding the lens to be ground and can move relative to the lens holding device to grind the lens The grinding device is characterized in that the grinding device includes a grinding sheet and a driving device connected to the grinding sheet to drive the movement of the grinding sheet, the driving device is provided with a spray cooling device, and the spray cooling device includes a The cooling nozzle on the back of the grinding s...

AI Technical Summary

Problems solved by technology

[0004] The grinding equipment in the prior art uses the lens holding device to hold and fix the lens so that the lens can be polished, but the grinding force in the grinding process is relatively large, and the lens is only absorbed and fixed by the holding device, which cannot Ensure the stability of the lens during the grinding process. Although there are currently clamps that can clamp the lens, these clamps need to be manually operated, and workers are required to perform manual operations before and after processing, which makes the operation more inconvenient and cumbersome
