Problems solved by technology

If the debris adhering to the surface of the shearing tool is not removed, it will greatly affect the shearing of the lens by the tool, thereby affecting the yield of the lens
If you clean the cutting tool and lens after cutting, it will take a lot of time, which is not conducive to improving production efficiency

Abstract

The invention discloses a lens shearing device, which comprises a shearing tool, a lens clamping device, a scrap shaving device and a scrap absorbing device, wherein the lens clamping device is opposite to the shearing tool, and the scrap shaving device and the scrap absorbing device are arranged between the shearing tool and the lens clamping device. The scrap shaving device is provided with a shaving blade opposite to the shearing tool, and the shaving blade is used for shaving off material scraps adhered to the surface of the shearing tool. The scrap absorbing device is arranged below the scrap shaving device, is opposite to the shaving blade, and is used for absorbing the material scraps shaved off by the shaving blade. The lens shearing device can prevent the material scraps from being adhered to the surfaces of the shearing tool and a lens, thereby improving the yield rate of the lens.

Description

technical field [0001] The invention relates to the technical field of shearing, in particular to a lens shearing device capable of removing debris. Background technique [0002] Chips are often generated when cutting workpieces with tools. Taking lens production as an example, lenses are mostly made of glass or plastic and are made by injection molding. Specifically, the injection molding process includes injection, pressure holding, cooling, demoulding, shearing, subsequent processing and other steps. [0003] See figure 1 , which is a schematic diagram of an injection component 1 with a plastic lens to be cut out from an injection molding machine. The ejection element 1 consists of a semi-finished plastic lens 2 molded from a four-cavity mold. The four mirrors 2 are located on the same circumference, and are connected to each other through the sprue block 4 and the flow path block 6 . After the lens 2 is formed, it is transported to the shearing zone together with th...
