Description

TECHNICAL FIELD

[0001] The utility model relates to light guide plate production equipment technical field, more specifically, it relates to a conveying device for light guide plate production line. BACKGROUND

[0002] The light guide plate is made of optical grade acrylic / PC plate material, and then high-tech material with extremely high refractive index and no light absorption is used to engrave light guide points on the bottom surface of the optical grade acrylic plate by laser engraving, V-shaped cross grid engraving and UV screen printing technology. The optical grade acrylic plate absorbs the light emitted from the lamp and stays on the surface of the optical grade acrylic plate. When the light hits each light guide point, the reflected light will spread to each angle, then break the reflection condition and shoot out from the front surface of the light guide plate. Through various light guide points with different densities and sizes, the light guide plate can emit light uniformly. The reflective sheet is used to reflect the light exposed on the bottom surface back to the light guide plate to improve the use efficiency of light. In the case of the same area luminance, the light emitting efficiency is high, and the power consumption is low. The single-sided microstructure array light guide plate is generally made by extrusion molding process.

The motor is installed at the lower part of the bracket by bolts. A drive sprocket is fixed on the output shaft of the motor. The drive shaft is installed at the front end of the bracket through a bearing. A transmission sprocket is fixed on one end of the drive shaft and connected to the drive sprocket through a chain. The driven shaft is installed at the rear end of the bracket through a bearing. The conveying belt is sleeved on the drive shaft and the driven shaft. The invention has the advantages of saving labor, time and effort.

[0005] However, when the light guide plate enters the next process, it cannot avoid the problem that the light guide plate may be damaged due to impact, friction and other reasons caused by the height difference between the conveying planes of the two processes, which affects the subsequent processing of the light guide plate and the quality of the finished product.
