Description

technical field [0001] The invention belongs to the technical field of lens injection molding, and in particular relates to an automatic equipment for lens injection molding and a control method thereof. Background technique [0002] At present: In the optical field, we usually use injection molded lenses, which are molded by plastic particles through an injection molding machine through a mold. Usually a lens mold contains multiple mold cavities, and one injection can mold multiple lenses. Branches and nozzles are connected between the lenses. After the injection molding is completed, the connected lenses need to be individually cut from the nozzle for subsequent process production. And every lens needs to be inspected to ensure that the lens is complete and flawless. The inspected lenses need to be uniformly hung on the corresponding jigs for subsequent batch processing. The existing lens injection molding equipment has a low degree of automation and mainly relies on m...

AI Technical Summary

Problems solved by technology

In order to realize automatic nozzle cutting, it is impossible to use the same set of molds for nozzle punching

Moreover, the space of the connection part of the nozzle is very small, and it cannot be realized with air shears.

[0007] It is necessary to carry out quality inspection for each lens. The transparency of the lens is high, and the accuracy of the defect detection is also high. However, the lens has a curvature, and the commonly used visual inspection methods are difficult to meet the requirements.

[0008] At present, these aspects of lens production still rely heavily on manual labor, and there is no set of related equipment in the market that can automate the above-mentioned lens process.
