Light guide plate laser precision micromachining, cleaning and suction device

Abstract

The invention discloses a laser precision micromachining, cleaning and suction device for a light guide plate, which includes a pick-up unit, a cleaning unit, a transmission unit and a processing unit; the pick-up unit picks up the light guide plate and moves it to the cleaning unit, or the light guide plate The cleaning unit is transferred to the transmission unit; the cleaning unit cleans the light guide plate; the transmission unit transports the light guide plate to the processing area of ​​the processing unit; the processing unit uses laser to process the light guide plate. The light guide plate is automatically cleaned before processing to remove various residues and oil stains on the light guide plate to improve the quality and precision of processing. Utilize the automatic pick-up device to increase the degree of automation, improve the efficiency of processing and reduce the cost. Through the coordinated work of multiple units, the automatic production of light guide plate scattering dot processing is realized.

Description

technical field [0001] The invention belongs to the field of high-end laser manufacturing equipment and advanced processing technology, and specifically relates to a laser precision micromachining, cleaning and absorbing device for a light guide plate. Background technique [0002] With the advent of the information age, displays have become the standard interface for man-machine communication. In the field of flat panel display in the new century, the technology is mature and the price is low, and the liquid crystal display (LCD) is in the dominant position. Moreover, within a period of time in the future, LCD will still be the mainstream in flat panel display (FPD), among which TFT-LCD has the largest proportion. [0003] Liquid crystal display (Liquid Crystal Display, LCD) has replaced the cathode ray tube display and has become the mainstream of the market due to its characteristics of low radiation, light, thin and short size, and low power consumption. LCD TVs, compu...

Problems solved by technology

In the process of developing the light guide plate, the performance of the light guide plate is still determined by the distribution of the light guide scattering dots, and in the current design method, there are problems of low dot design efficiency and unguaranteed effect

[0004] At present, the manufacturing methods of light guide plate scattering dots include mold forming method, ink printing method and laser processing method, etc., but in all processing processes, some impurities and oil stains on the surface of the light guide plate are not removed, which affects the light guide plate scattering. The processing quality of dots can easily lead to the problems of high defect rate and low processing efficiency of light guide plate scattering dots
