Light guide plate full-automatic numerical control polishing apparatus

Abstract

The invention discloses a light guide plate full-automatic numerical control polishing apparatus. The light guide plate full-automatic numerical control polishing apparatus comprises a workbench, a positioning device, a polishing device, a material taking device and a dust collection cover. The positioning device, the polishing device, the material taking device and the dust collection cover are arranged on the workbench. The workbench is provided with at least one rotary platform for fixing a light guide plate. The rotary platform is connected with a rotation driving mechanism for driving therotary platform to rotate horizontally. The workbench is further provided with an X-axis-direction driving mechanism and a Y-axis-direction driving mechanism, wherein the X-axis-direction driving mechanism can drive the rotary platform to horizontally move in the X-axis direction back and forth, and the Y-axis-direction driving mechanism can drive the rotary platform to horizontally move in the Y-axis direction back and forth. The light guide plate full-automatic numerical control polishing apparatus is further provided with a control system. A full-automatic operation mode is adopted by thelight guide plate full-automatic numerical control polishing apparatus, all the mechanisms can automatically return, and therefore, the efficiency is improved; and additionally, by using a first positioning mechanism and a second positioning mechanism in cooperation, datum positioning is formed by the side face, positioned by adopting the first positioning mechanism or a positioning plate, of thetwo opposite side faces of the light guide plate, buffer compensation type positioning is formed by the other side face positioned by adopting the second positioning mechanism, and then, accurate positioning is achieved; and the dust collection efficiency is as high as 99.5%.

Description

technical field [0001] The invention belongs to the technical field of automation equipment, and in particular relates to an automation equipment suitable for the polishing process of a light guide plate. Background technique [0002] The working principle of the mobile phone screen light guide plate is derived from the liquid crystal display screen of the notebook computer. It is a high-tech product that transforms the line light source into a surface light source. Optical-grade acrylic (PMMA) / PC is used as the base material, and the backlight module technology of LCD display and notebook computer is used to pass through the high light transmission rate of the light guide point, and the light guide point is calculated by the computer, so that the light of the light guide plate is refracted into Manufacture and molding of surface light source in uniform light state. It has distinctive features such as ultra-thin, ultra-bright, uniform light guide, energy saving, environment...

AI Technical Summary

Problems solved by technology

In the polishing process of the mobile phone light guide plate, since the polishing motor is a high-speed motor with a speed of 20,000 revolutions per second, the position accuracy of the light guide plate product is required to be high. However, the positioning accuracy of the positioning device in the prior art is not ideal. Easy to shift, unable to achieve precise positioning, affecting product quality

[0004] For example, the positioning mechanism disclosed in the Chinese patent "Positioning Mechanism and Its Conveying Device and Positioning Method" (CN 101279679 B) is not accurate enough and needs to be improved.

[0005] In addition, during the polishing process of the light guide plate of the mobile phone, a large amount of dust will be generated. The design of the suction hood in the prior art is not reasonable enough. For example, the air inlet of the suction hood is narrow, the dust collection area is small, and part of the dust will still diffuse into the air. , and the inside of the vacuum hood is easy to block, etc., making the vacuum effect unsatisfactory and affecting product quality
