Automatic marking machine for micro-engraving invisible mark in inner progressive resin lens

Abstract

The invention relates to an automatic marking machine for micro-engraving an invisible mark in an internal progressive resin lens. The automatic marking machine for micro-engraving the invisible markin the internal progressive resin lens comprises a workbench, a manipulator (3) and a marking system (5), wherein mounting frames are located on two sides of the workbench; a conveying belt for conveying a material box to move is mounted on the mounting frames; an automatic discharging system (6) is arranged on the mounting frame on one side; an automatic material receiving system (2) is arrangedon the mounting frame on the other side; the manipulator (3) is arranged on the workbench (7), located on one side of the conveying belt (1), and used for taking out the lens in the material box (108)and placing the lens on a lifting clamping mechanism (4) located on the workbench (7); and the marking system (5) is arranged on the workbench (7), located right above the lifting clamping mechanism(4) and used for marking the lens on the lifting clamping mechanism (4). The invisible mark is engraved to the interior of the resin lens by adopting a laser-micro-engraving process and cannot be covered by a subsequent processing process, so that the mark is continuously and clearly visible.

Description

technical field [0001] The invention relates to the field of high-end customized resin lens processing, in particular to an automatic marking machine for inner engraving invisible marks of inner progressive resin lenses. Background technique [0002] With the development of the optical industry and the machine tool industry, lenses that are more suitable for human eyes and more comfortable can be processed and produced. Such as all-focal lenses, ring focus lenses, progressive multifocal lenses and other private high-end customized lenses. High-end customized lenses are comfortable to wear, effectively relieve eye fatigue, and have a significant effect on the prevention and control of young people's vision. High-end customized lenses are more and more recognized by consumers due to their great advantages, and the market share is increasing year by year. High-end customized lenses are different from traditional single-focus lenses due to their special processing. After the ...

Problems solved by technology

[0003] The existing marking machine in the market is manual CO 2 Infrared laser marking machine, the engraved logo is engraved on the surface of the resin lens, the marking power is not easy to control, the marking depth is deep, the line width is wide, the logo trace is obvious, and the comfort is reduced when wearing

[0004] Since the logo is engraved on the surface of the resin lens, the subsequent hardening and coating process will harden the lens surface, sometimes the logo will fade or disappear, which will bring difficulties to the subsequent lens assembly

CO 2 The infrared laser is a thermal light source, and the engraved marks are formed by ablation. Harmful gases will remain during engraving, which will pollute the working environment and cause damage to the health of operators.
