Abstract

Embodiments of the present invention provide a surface light source printing device and a printing method thereof, which relate to the technical field of backlights and can solve the problems of high cost and low mass production efficiency of surface light sources due to long transfer time. The punching device includes: a grabbing mechanism, the grabbing mechanism includes at least one grabbing group, each grabbing group includes a plurality of grabbing arms, and the plurality of grabbing arms in the same grabbing group are used to extract from the expansion plate simultaneously Grab multiple LED wafers and transfer multiple LED wafers to the flexible circuit board; the stroke amplification mechanism is used to enlarge the distance between the multiple grabbing arms that grab the LED wafers, so that two adjacent The spacing between the grabbing arms matches the spacing between adjacent LED wafers on the flexible circuit board; The distance between two adjacent grasping arms matches the distance between adjacent LED crystal elements to be grasped on the expansion board. The invention is used for making a 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...
