Light guide plate screen dot processing equipment and method

Abstract

The invention relates to the technical field of light guide plate screen dot processing, in particular to light guide plate screen dot processing equipment and method. The light guide plate screen dot processing equipment comprises a conveying table used for conveying a light guide plate, fixing assemblies used for fixing the light guide plate are arranged on the two sides of the conveying table correspondingly, and a fixing frame is erected above the conveying table; and a cross beam is movably arranged at the bottom of the fixing frame, a steel die roller is rotatably arranged at the bottom of the cross beam, protrusions are evenly arranged on the outer side wall of the steel die roller, and the cross beam is provided with a heating piece used for heating the steel die roller and a hot pressing assembly used for driving the steel die roller to ascend and descend. The light guide plate screen dot processing equipment and method have the effects of improving the light guide plate screen dot processing efficiency, precision and environmental friendliness.

Description

technical field [0001] The present application relates to the technical field of dot processing of a light guide plate, in particular to a dot processing equipment and method of a light guide plate. Background technique [0002] In the backlight module, there is usually a light source on the side of the light guide plate, and the transmission direction of the light source propagates along the side of the light guide plate; in order to enable light to be emitted from the side of the light guide plate, the light guide plate needs to have a dot structure to scatter the light. [0003] In order to shape the dots of the light guide plate, an existing technology is to perform silk screen printing on the light guide plate, print light guide ink on the light guide plate, and then cure it in an oven. Due to the high temperature and long working hours of the oven, the energy consumption is large, which is not conducive to energy saving and environmental protection. And the finished p...

AI Technical Summary

Problems solved by technology

Due to the high temperature and long working hours of the oven, the energy consumption is high, which is not conducive to energy saving and environmental protection

And the finished product is easy to oxidize and fall off

[0004] Another more conventional method is laser dotting. The stability of laser dotting is better, but the processing speed is relatively slow and the printing efficiency is low.

In particular, the power of the design and the laser machine must match well, otherwise the effect of the original design will not be achieved.
