Lens kneading device

Abstract

The invention discloses a lens kneading device, which has an active rod, a linkage rod, a lens suction cup, and a lens placement mold. Wherein: the active rod can be driven to rotate around an axis; the upper end of the linkage rod is connected to the bottom end of the active rod with a universal joint structure; the lens suction cup is connected to the lower end of the linkage rod, and the lens suction cup has a first lens fixing part, The first lens fixing part has a first opening, the first opening extends into the lens suction cup and has a first air suction hole, and the first air suction hole is connected with a first air suction unit; the lens placing mold has a second lens fixing part, And the center of the lens placement mold is located on the axis, and at least one of the active rod or the lens placement mold can move up and down along the axis. The composition structure of the present invention allows the glue to be evenly applied to the interface between the two lenses, and the air bubbles in the glue can be completely discharged, while maintaining the advantages of high production efficiency.

Description

technical field [0001] The invention relates to a lens kneading device, in particular to a lens kneading device which can automatically apply glue evenly. Background technique [0002] In the process of making eyeglass lenses or photographic lens lenses, sometimes it is necessary to glue two lenses together to form a composite optical component, and in the bonding process, the glue needs to be evenly spread on the interface between the two lenses On, and there must be no air bubbles in the glue, otherwise the path of light will be deflected and its optical effect will be impaired. In order to achieve the above purpose, in the past, the two lenses were kneaded manually. Using this method, each part of the interface between the two lenses can be squeezed, so that the glue can be evenly applied to the interface of the two lenses and the adhesive can be discharged. Air bubbles in the glue, but the manual method is not only time-consuming and inefficient, but also easy to cause ...

Problems solved by technology

In order to achieve the above purpose, in the past, the two lenses were kneaded manually. Using this method, each part of the interface between the two lenses can be squeezed, so that the glue can be evenly applied to the interface of the two lenses and the adhesive can be discharged. Air bubbles in the glue, but the manual method is not only time-consuming and inefficient, but also easy to cause occupational injuries to the hands of workers

[0003] In order to solve the above-mentioned inconveniences, some operators have developed an automatic device for lens kneading, such as Patent No. WO95 / 13904. This device first compresses the upper and lower lenses, and then drives the upper lens to rotate coaxially. However, in the concentric rotation method, the glue can only diffuse from the coating at most, and it cannot spread the glue evenly on the interface between the two lenses, nor can it make the bubbles in the glue completely discharge

[0004] Also, as disclosed in the CN 208737111 patent case, the automatic rubber kneading device, after the device compresses the upper and lower lenses, then drives the upper lens to move in a linear reciprocating direction relative to the lower lens, but due to the upper The junction of the lower lens and the lower lens is a circular surface, so this kind of reciprocating glue kneading method in a single direction will cause the upper and lower lens to be unable to be squeezed on both sides of the hanging direction, and there will also be no way to make the glue stick. Spread evenly, and the problem of not being able to completely discharge the air bubbles in the glue exists
