Problems solved by technology

[0003] In some bi-convex lenses with high refractive index, the mirror surface needs to be finely ground and polished in the final stage. Generally, the lens is clamped on the fixture, and then polished with a grinding tool, but because of the need to focus, manual focus is not It is very troublesome and cannot be quickly clamped and processed, and the general equipment is processed separately, which cannot guarantee work efficiency

Embodiment 1

[0049] like Figure 1-Figure 8 As shown, the power mechanism 5 includes a main shaft 51, a sheave 52, a rotating wheel 53, and a linkage pin 54. One end of the main shaft 51 is connected to the limit plate 21 of the rotating mechanism 2, and the other end of the main shaft 51 is connected to the sheave 52. One end of the sheave 52 is provided with a The rotating wheel 53 is provided with a linkage pin 54, and the lower end of the rotating wheel 53 is connected to the first motor 55. When the first motor 55 is started, it drives the rotating wheel 53 to rotate, and when the rotating wheel 53 rotates, the linkage pin 54 is driven to make the rotating wheel 53 rotate. The linkage pin 54 drives the sheave 52 and the main shaft 51 to rotate intermittently, so that the limit disk 21 rotates intermittently; the rotating mechanism 2 includes the limit disk 21, the limit hole 22, and the rotating disk 23. The limit disk 21 is formed with eight There are limit holes 22, the lower end of...

Embodiment 2

[0051] The difference between this embodiment and Embodiment 1 is:

[0052] like Figure 9 , the power mechanism 5 includes a main shaft 51, a passive gear 511, an intermittent gear 512, and a second motor 513. One end of the main shaft 51 is connected to the limit plate 21 of the rotating mechanism 2, and the other end of the main shaft 51 is connected to the passive gear 511. The passive gear 511 and the intermittent gear 512 The lower end of the intermittent gear 512 is connected to the second motor 513. When the second motor 513 starts, it drives the intermittent gear 512 to rotate, and the intermittent gear 512 and the driven gear 511 are intermittently meshed, so that the driven gear 511 drives the main shaft 51 to rotate intermittently, so that the The limit plate 21 rotates intermittently.

[0053] The use method of the grinding surface device for high refractive index lens processing comprises the following steps:

[0054] a. When the lens needs to be processed, pla...

Abstract

The invention discloses a surface polishing device for high-refractive-index lens processing. The surface polishing device comprises a rotating mechanism for driving a to-be-processed lens to rotate,an adsorption mechanism for fixing the to-be-processed lens and a limiting mechanism for limiting the adsorption mechanism, and the adsorption mechanism is arranged on the inner side of the rotating mechanism; and a base is arranged at the lower end of the rotating mechanism, a power mechanism is connected to the power end of the rotating mechanism, the limiting mechanism is arranged on the innerside of the adsorption mechanism, four polishing mechanisms are arranged on the upper side of the rotating mechanism, and the power mechanism is arranged in the base. The adsorption mechanism is driven by the limiting mechanism, so that the adsorption mechanism forms the negative pressure for adsorbing the lens, the stability of the lens is guaranteed, the machining precision is improved, taking and placing are convenient, the precision during lens placing can be guaranteed through cooperation of the rotating mechanism and the adsorption mechanism, and thus the processing efficiency is improved while the processing precision is improved.

Description

technical field [0001] The present invention relates to the field of lens processing, in particular to a surface grinding device for processing a high refractive index lens and a method for using the same. Background technique [0002] A lenticular lens is a lenticular lens sheet, which includes an incident surface and an exit surface, and is characterized in that the focal length of the middle part of the lens surface is longer, and the focal length of the end parts of each lens surface is shorter. Lenticular lenses are primarily used to focus light from point sources or to transmit images to other optical systems. [0003] In some high-refractive-index biconvex lenses, the mirror surface needs to be finely ground and polished in the final stage. Generally, the lens is clamped on a fixture, and then polished with an abrasive tool. However, due to the need to focus, manual focus is required. It is very troublesome, and cannot be clamped and processed quickly, and the genera...
