The invention discloses a light guide plate lattice point processing device based on a double-rotating motor. The light guide plate lattice point processing device comprises a machine frame and a processing platform, wherein the processing platform is used for fixing a light guide plate, and the processing platform is arranged on the machine frame and movably connected with the machine frame; themachine frame is further provided with a laser device, a reflection mechanism used for reflecting laser emitted by the laser device to the light guide plate and a driving mechanism used for driving the reflection mechanism to rotate; the reflection mechanism comprises a rotating disc, a first reflecting mirror group used for reflecting the laser emitted by the laser device and a second reflectingmirror group used for reflecting laser reflected by the first reflecting mirror group, wherein the output end of the driving mechanism is connected with the rotating disc, and the second reflecting mirror group is fixed on the rotating disc; and the driving mechanism comprises a first rotating motor for driving the rotating disc to rotate and a second rotating motor for driving the first reflecting mirror group to rotate, wherein the second rotating motor is fixed on the rotating disc. According to the light guide plate lattice point processing device based on the double-rotating motor, corresponding optical paths are basically consistent when lattice points on the light guide plate are processed, so that the processing quality of the lattice points on the light guide plate is improved.

Description

technical field [0001] The invention relates to the technical field of light guide plate processing, in particular to a dot processing device for light guide plates based on double rotating motors. Background technique [0002] Liquid crystal display devices have the advantages of lightness, thinness, and low power consumption, and are widely used in modern information equipment. Since the liquid crystal in the liquid crystal display panel itself does not have luminous characteristics, in order to achieve the display effect, a backlight module must be provided for the liquid crystal display panel. The function of the backlight module is to provide the liquid crystal display panel with a surface light source with sufficient brightness and uniformity. The role of the light guide plate in the backlight module is to guide the scattering direction of light to improve the brightness and control the uniformity of the brightness. Therefore, the design and manufacture of the light gu...

Problems solved by technology

[0003] In the prior art, when using laser to process dots on the light guide plate, linear processing components are often used to reflect the laser light, so that the optical paths of different lasers reaching the surface to be processed on the light guide plate are inconsistent, resulting in different depths of dots on the light guide plate and poor quality
