Problems solved by technology

In this way, it not only makes the lens manufacturing process complicated, but also tends to increase the production cost
[0004] An important reason why the prior art adopts the method of first cutting the mother sheet into square lenses and then grinding the square lenses into circles with a rounding machine is due to the limitation of the lens cutting device.
For example, the lens cutting device in the prior art usually can only cut linearly, so for the cutting of circular products, it is necessary to cut the product into polygons to approximate the circle. The process is complicated and difficult to control, so it is difficult to directly cut circular lenses , followed by a rounding process

Embodiment Construction

[0014] The device and method for cutting a circular lens will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] Please refer to FIG. 1 , which is a cross-sectional view of a cutting device 100 for cutting circular lenses according to a first embodiment of the present invention. The cutting device 100 includes a rotary connection device 1 with a through hole 11 , a cutter 2 and a punching device. Wherein, the cutter 2 is arranged at the end 12 of the rotary connection device 1; the rotary connection device 1 is used to drive the cutter 2 to rotate and cut. The punching device includes a connecting rod 4 and a punching head 5, the connecting rod 4 is passed through the through hole 11; the punching head 5 is at the end of the connecting rod 4 on the side of the tool 2, and its center in the punching direction passes through the tool The center of the circle formed by the rotation of the blade 21 of the tool 2, the stampin...

The cutter is set to one end of the rotating and connecting unit, and one punching unit includes one link rod set inside the through hole in the rotating and connecting unit and one punching head set beside the cutter. The present invention provides process of cutting circular lens. The present invention can facilitate production of circular lens.

Description

technical field [0001] The invention relates to the field of lens processing, in particular to a device and method for cutting lenses into circles. Background technique [0002] With the development of science and technology, the application of various optical lenses has been continuously expanded; correspondingly, in order to meet the market demand, the production technology of optical lenses has also been continuously improved. [0003] In the prior art, for the preparation of circular lenses, the mother sheet is generally first cut into square lenses, and then the square lenses are ground into circular shapes with a rounding machine. However, in the grinding process of the lens, the lens needs to be fixed to balance the shearing force generated by the grinding wheel, and different jigs need to be used for grinding according to different parts of the grinding lens. In this way, it not only makes the lens manufacturing process complicated, but also tends to increase the pr...
