Machining device of lens and machining method thereof

Abstract

The invention provides a machining device of a lens and a machining method thereof. The machining device mainly comprises a conical round roller linkage assembly, the conical roller linkage assembly comprises a discharging roller (1), a transmission roller (2), a lens face roller (3), a structure roller (5) and a receiving roller (7) with small radius ends connected through bearings, each conicalround roller in the conical round roller linkage assembly can do circumferential motion with the connecting end as the center, and an annular groove structure is formed on the surface of the structureroller (5) in a stacked manner; the machining device further comprises a glue injection circular mechanism, the glue is injected into the gap between the lens face roller (3) and the structure roller(5), and the production device further comprises a curing mechanism (4) arranged below the structure roller (5). The machining device is good in finished product appearance and uniformity, and is particularly suitable for large-size display screen production and application, the product yield is improved, cost is reduced, and it is ensured that the screen has the good visual effect.

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
