Specific implementation mode：
The utility model is further illustrated with reference to specific embodiments and the drawings.
As Figure 1-Figure 4, described in the utility model is a kind of both sides plece-cliped type backlight assembly, which includes
Glue frame 1 and light guide plate 2, wherein：Chamfered section 21 is formed at the top two corners of the light guide plate 2, interval forms two in the middle part of top
Triangle inner fovea part 22 forms three sections of flat parts 23 between two chamfered sections 21 and two triangle inner fovea parts 22；The glue frame 1
Inside be formed with the identical glue frame window 100 of 2 shape of the light guide plate, i.e., the upper side frame of glue frame window 100 have on light guide plate 2
The 22 corresponding triangular protrusions 11 of triangle inner fovea part on side, and the upper side frame inner wall and lower frame inner wall of glue frame window 100
The upper supporting surface of support light guide plate 2 back side top edge and lower edge respectively is also extended to form towards 100 middle part of glue frame window respectively
12 and lower support lugn 13；In the two sides of the light guide plate 2, is each extended over from 2 back side of light guide plate to both sides and form several cards
Ear 24, and the thickness of card ear 24 is less than 2 thickness of light guide plate (the about half of 2 thickness of light guide plate)；Accordingly, in glue frame window
At 100 both sides inner wall, bayonet corresponding with card ear 24 14 is formed towards 1 back side direction of glue frame；In this way, the back side of light guide plate 2
Upper and lower both sides are supported by upper supporting surface 12, lower support lugn 13 respectively, and the card ear 24 of the both sides of light guide plate 2 and 1 inner wall of glue frame
Bayonet 14 form screens, prevent light guide plate 2 from removing glue frame 1 to front, imitated to make the positioning of light guide plate 2 and glue frame 1 assemble
Fruit is more preferably；In terms of 2 front of light guide plate, the height and position of the card ear 24 of both sides is different, 14 high and low position of bayonet of corresponding glue frame 1
Difference can avoid assembling from malfunctioning with fool proof.
In above-mentioned backlight assembly semi-finished product, at the upper side frame inner wall of the glue frame 1, the top of upper supporting surface 12, with lead

LED light source, is convenient for the installation of LED light source, and can reduce the thickness of entire backlight assembly, keeps entire backlight assembly thinner.
In above-mentioned backlight assembly semi-finished product, the thickness of the card ear 24 of 2 both sides of the light guide plate is 0.01mm~0.5mm, long
Degree is 1mm~3mm.
In above-mentioned backlight assembly semi-finished product, 13 width outstanding of lower support lugn of the lower frame inner wall of the glue frame 1 is
0.1mm~1mm.
In above-mentioned backlight assembly semi-finished product, reflector plate 4 is also equipped in the front in the front of the glue frame 1, light guide plate 2.
The step of the utility model both sides plece-cliped type backlight assembly semi-finished product, is as follows：
1) glue frame is fitted into glue frame localization tool by, and glue frame is face-up, and both sides bayonet is directed downward；Jig is with turntable
Move to next station；
2) light guide plate is face-up adsorbed to using vacuum slot face glue frame glue frame window top position then it is true
Suction mouth moves down, and makes the card ear of light guide plate both sides first with glue frame both sides bezel contact, and further control vacuum slot pushes at this time,
The both sides up and down of light guide plate are made to be supported respectively by the upper supporting surface of glue frame upper and lower side frame and lower support lugn, while in light guide plate
The card ear of portion's sinking and bending and both sides squeezes glue frame both sides outward makes glue frame both sides extend out, and then makes the Ka Erka of light guide plate both sides
It in the bayonet for entering glue frame both sides, then controls vacuum slot release light guide plate and moves up, complete light guide plate positioning and be packed into glue frame；Turn
Move to next station；
3) recycles the manipulator of next station and vacuum slot reflector plate to fit to the top of light guide plate, completes backlight
The assembling of component semi-finished product.
Backlight assembly semi-finished product are finally transferred to the fitting that other stations carry out other membrane materials, routinely sequentially stack it
His membrane material finally unifies pressing, forms the assembling of backlight assembly semifinished or finished goods.
The utility model using the above structure, by change jig structure and changes assembling sequence, after first assembling light guide plate
