Problems solved by technology

This detection method is not only inefficient, but also impossible to detect defective products in time.
Second, since the dot screen printing of the light guide plate cannot be reworked, there is usually no automatic remedial device when processing the dots, and the product yield is low

Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] Such as Figure 1-3 As shown, the embodiment of the present invention includes a light guide plate side processing center, a light guide plate screen printing dot processing main device, and a light guide plate dot replenishment device. The light guide plate side processing center mills and polishes the side of the light guide plate to be processed, and the light guide plate screen printing dot processing main device performs dot processing on the milled and polished light guide plate. The dot replenishing device for dots on the light guide plate performs dot replenishment processing for missing ink dots on the light guide plate. The light guide plate side processing center includes a first input device 1 , a first numerical control device 2 , an auxiliary control device 3 , a first servo system 4 , a detection feedback device 5 and a first processing center ...

Abstract

The invention discloses a light guide plate silkscreen dot processing device comprising a light guide plate silkscreen dot processing main body device and a light guide plate screen dot supplementing device. Screen dot processing is performed on a light guide plate by the light guide plate silkscreen dot processing main body device. Dot supplementing processing is performed on the positions of the light guide plate without ink dot by the light guide plate screen dot supplementing device. The light guide plate silkscreen dot processing main body device comprises a CCD image sensor, a treadmill type silkscreen machine, an A / D device, a processor and a sound-light alarm device. The light guide plate screen dot supplementing device comprises an input device, a numerical control device, a servo system and a processing center main body. The input device, the numerical control device, the servo system and the processing center main body are connected in turn from the front to the back. The light guide plate silkscreen dot processing device has advantages of being high in processing product yield rate, high in processing degree of automation, online in feedback and timely in dot supplementing.

Description

technical field [0001] The invention relates to a processing device, in particular to a screen printing dot processing device for a light guide plate. Background technique [0002] The design principle of the light guide plate is derived from the liquid crystal display screen of the notebook computer. It is a high-tech product that transforms the linear 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. The product adopts the principle of spectral analysis combined with digital UV printing technology and is produced under constant temperature, constant humidity and dust-free environ...
