Abstract

The embodiment of the invention provides a beating device for a surface light source and a beating method thereof, and relates to the technical field of a backlight source. The problem that the surface light source has high cost and low mass production efficiency due to excessive transfer time is solved. The beating device comprises a gripping mechanism, the gripping mechanism comprises at least one gripping group, each gripping group comprises a plurality of gripping arms, and a plurality of the gripping arms in the same gripping group are used for simultaneously grasping a plurality of LED wafers from a crystal expansion plate and transferring a plurality of the LED wafers to a flexible circuit board; a stroke amplifying mechanism is used for amplifying spacing between the plurality of gripping arms of the LED wafers to make spacing between the adjacent two gripping arms match the spacing between positions to place the adjacent LED wafers on the flexible circuit board; a stroke reduction mechanism is used for reducing the spacing between the plurality of gripping arms which release the LED wafers, so that the spacing between the adjacent two gripping arms matches the spacing between the adjacent LED wafers in the plurality of LED wafers to be captured on the crystal expansion plate. The device is used for making the surface light source.

Description

technical field [0001] The invention relates to the technical field of backlight sources, in particular to a surface light source mounting device and a mounting method thereof. Background technique [0002] In recent years, due to the wider color gamut of Mini LED (Light Emitting Diode, light-emitting diode), which can bring advantages such as higher brightness, longer service life and higher contrast ratio, it has been favored in the field of backlight for liquid crystal displays. a high degree of attention. However, because the existing Mini LED die-bonding methods are all single-shot crystals, and the die-bonding is carried out by positioning with a robot arm. This leads to too long transfer time of Mini LED, which in turn leads to higher cost of Mini LED and lower mass production efficiency. Contents of the invention [0003] Embodiments of the present invention provide a surface light source printing device and a printing method thereof, which can solve the problems...
