Embodiment 1

[0030] Embodiment 1, the concrete structure of the present invention is as follows:

[0031] Please refer to the attached Figure 1-2 According to the present invention, the mechanism for improving the brightness performance consistency of the liquid crystal screen and the backlight module after assembly includes an assembly device for matching and assembling the liquid crystal screen and the backlight module, and also includes:

[0032] The liquid crystal screen conveying mechanism that is located on a first platform 101, this liquid crystal screen conveying mechanism includes an incoming material scanning code device 9 for identifying the penetration rate of the liquid crystal screen, a linear stroke 111 with side rails, a A sorting manipulator mechanism 11 arranged on the side rail and capable of moving in the X-axis along the side rail, and a sorting manipulator mechanism 11 set on the opposite side of the sorting manipulator mechanism 11 and storing the penetration rate o...

Embodiment 2

[0043] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of the liquid crystal screen conveying mechanism of the present invention.

[0044] First of all, the liquid crystal screen in the present invention is provided with a two-dimensional code, and the two-dimensional code stores three types of transmittance information: high, medium and low. In the present invention, the multi-layer liquid crystal screen storage board 100 is arranged in three layers, from top to bottom:

[0045] The first layer of liquid crystal screen storage board is a high-transmittance liquid crystal screen storage board, which is used to store high-transmission liquid crystal screens;

[0046] The second layer of liquid crystal screen storage board is a liquid crystal screen storage board with medium transmittance, which is used to store liquid crystal screens with medium transmittance;

[0047] The third layer of liquid crystal screen storage board is a low-transmittance liqui...

Embodiment 3

[0050] Such as figure 2 as shown, figure 2 It is a structural schematic diagram of the conveying mechanism of the backlight module of the present invention.

[0051] The backlight module loading manipulator transports the backlight module to the backlight module scanning position, provides position marks for the classification and storage of backlight modules by scanning the QR code on the backlight module, and then transports the backlight module through visual positioning and conveyance To the lighting station capable of lighting the backlight module, this station is also a brightness detection station. Through the detection of the brightness detector 21, it is distinguished whether the brightness of the backlight module is one of high, medium and low brightness. Brightness classification storage mechanism 19. The backlight module grabbing mechanism 22 transports the backlight module according to the specific matching relationship to the assembly position and assembles ...

Abstract

The invention discloses a mechanism for improving module brightness performance consistency after assembly of a liquid crystal screen and a backlight module. The mechanism comprises assembly equipment, wherein the assembly equipment is used for assembling the liquid crystal screen and the backlight module in a matching way, the mechanism comprises three constituent parts, a first part is a liquidcrystal screen penetration rate partition mechanism and is used for acquiring corresponding liquid crystal screen penetration rates by code scanning and classifying and storing the corresponding liquid crystal screen penetration rates, a second part is a backlight module brightness detection and partition mechanism and is used for measuring brightness class after the backlight module is conductedand lighten and classifying and storing the brightness class, and a third part is a matching assembly part, is used for obtaining high, medium and low penetration rates by a CIM system and is assembled with the backlight module according to a certain relation of the high, medium and low penetration rates. By the mechanism, the brightness consistency of the produced LCD liquid crystal module can beensured, the stability of the produced LCD liquid crystal module is improved, the production yield of the liquid crystal module is improved, and the one-time passing rate of a product is improved. Bythe mechanism, full-automatic production is achieved, and automatic identification, classification and storage is achieved.

Description

technical field [0001] The invention relates to the technical field of automation equipment, in particular to a mechanism for improving the brightness performance consistency of a liquid crystal screen and a backlight module after assembly. Background technique [0002] The following PANEL is the LCD screen, and BLU is the backlight module. [0003] In traditional module production, PANEL and BLU are randomly assembled, and there is no matching system. That is, the different penetration rates of PANEL are randomly combined with the different brightness of BLU. The brightness of the product assembled in this way is not uniform, which is not conducive to the stability and consistency of the product. [0004] The PANEL and BLU assembly and matching mechanism is suitable for improving the brightness consistency of the modules after PANEL and BLU assembly, and ensuring the brightness uniformity of the produced liquid crystal module products. PANEL is a transparent glass materi...
