Abstract

The invention relates to a shearing blade for a plastic lens pouring gate. The shearing blade comprises a positioning portion and a shearing portion connected with the positioning portion; in the thickness direction of a shearing blade body, a first surface and a second surface are arranged oppositely on the shearing portion; in the direction away from the positioning portion, the thickness of theshearing portion gradually decreases, and the first surface and the second surface intersect at the farthest end to form a knife-edge structure; and the first surface is a rough surface. The first surface of the shearing portion is arranged as the rough surface, so that when a plastic lens is sheared by the shearing blade, the first surface can be used for directly processing the shearing surfaceon the plastic lens into the rough surface; and the reflection effect of a traditional smooth shearing surface on light is eliminated, so that the shearing surface formed by using the shearing bladehas a good suppression effect on the formation of stray light, and the shearing blade is beneficial to improving the imaging quality of the lens.

Description

technical field [0001] The invention relates to a shearing blade, in particular to a shearing blade used for a gate of a plastic lens. Background technique [0002] In recent years, with the increasing development of portable electronic devices such as mobile phones and tablet computers, miniaturized or even ultra-miniature lenses mounted on such devices have also begun to flourish. As a result, users not only put forward higher requirements for the imaging resolution capability of the lens, but also require the lens to have better stray light suppression capability. [0003] Since there are more and more imaging lenses in the existing miniaturized lens modules, most of the imaging lenses are made by injection molding. Considering the processing of the plastic lens in the subsequent process, before it is boxed, it is necessary to use a lens gate cutting blade to cut the glue inlet of the plastic lens. According to the current technology, the edge of the lens gate shearing ...
