Lens processing equipment and processing method thereof

Abstract

The invention provides a lens processing equipment and a processing method thereof. The production equipment mainly includes a conical circular roller linkage assembly. The conical circular roller linkage assembly includes a discharge roller (1) whose small radius ends are connected to each other through bearings, a transmission roller (2), the mirror roller (3), the structure roller (5) and the receiving roller (7), each tapered roller in the tapered roller linkage assembly can perform circular motion around its connecting end; The surface of the structural roller (5) is stacked with an annular groove structure; the production equipment also includes a glue injection circulation mechanism, which injects glue into the gap between the mirror roller (3) and the structural roller (5); the production equipment also includes A curing mechanism (4), which is arranged under the structure roller (5). The finished product of the invention has good appearance and uniformity, is especially suitable for the production and application of large-size display screens, improves product yield, reduces costs, and ensures that the screen has better visual effects.

Description

technical field [0001] The invention relates to lens processing equipment and a processing method thereof, belonging to the technical field of optical component manufacturing. Background technique [0002] The large-size annular groove structure lens is a kind of lens with a smooth surface on one side and concentric circles or Archimedes spirals on the other side. It is currently used more and more widely in various industries, such as: used in solar concentrating The field is one of the important optical components in the concentrated solar system (CPV), and its performance directly affects the concentration rate of the CPV system; when applied in the display field, its main function is to project the The light with a large divergence angle is collected, so that the original divergent light can be concentrated in the viewing angle of the viewer, so as to achieve the purpose of increasing the brightness of the image. Under this background and the demand of the market, it is...

AI Technical Summary

Problems solved by technology

In the prior art, there is a lack of control measures for thickness uniformity, deformation of the glue before curing after molding, and measures to eliminate air bubbles at the bottom of the glue / base

In addition, in the existing tapered roller production technology, refer to the content disclosed in the previous patent with the patent number ZL201410170395. The stability of the structure (4V glue fluidity) cannot be guaranteed before the obtained structure is cured; the influence of air bubbles in the glue cannot be completely excluded; it cannot be applied to mass continuous production
