Background technology
The processing of backlight module is often there are film process in the related art, and the diaphragm used in film process is general
Include two layers, one layer is stayed in the functional layer on backlight module, and one layer is bottom, needs to tear bottom after pad pasting is completed
It goes.Backlight kludge of the prior art is equipped with a guide roller, is wound with adhesive tape on guide roller, passes through guide roller and backlight mould
The relative motion of group causes the adhesive tape adherency that the bottom of backlight module upper diaphragm is directed on roller, is finally completed going for diaphragm bottom
It removes.
But the guide roller of the prior art is using the film made of one whole rigid plastics on pole, with backlight module
Piece touch initial stage easily on diaphragm formed an impression.
The content of the invention
Technical problem to be solved in the utility model is：A kind of guide roller of backlight kludge is provided, is connect with diaphragm
It impacts small during touching, will not cause to leave impression on diaphragm.
Technical solution adopted in the utility model is：A kind of guide roller of backlight kludge is provided, it includes shaft, institute
It states and is sequentially equipped with multiple idler wheels in shaft vertically, it is characterised in that：A castor is equipped between two idler wheels of arbitrary neighborhood, it is living
Central through hole is equipped in driving wheel, the castor is fixedly connected by central through hole with shaft, and the outer diameter of the castor is less than
Or the outer diameter equal to idler wheel, the castor is interior to be equipped with an annular chamber, and an air bag, the outside of the castor are equipped in annular chamber
Several through holes are evenly distributed on wall, when pouring air in air bag to the lateral wall of air bag and the madial wall of annular chamber against when institute
State the position evagination that air bag is located at corresponding to through hole and form a bulge, the part via through holes of the bulge it is exposed with outside castor,
And the vertical range of the vertex of bulge to shaft axis is more than the 1/2 of idler wheel outer diameter.
The air bag is equipped with a gas nozzle close to the position of shaft, and gas channel, the side of the shaft are equipped in the shaft
Be located at the position corresponding to gas nozzle on wall and be equipped with connecting tube, the lower end of the connecting tube connects with gas channel, connecting tube it is upper
End is connected with the gas nozzle of air bag.
The air bag is loop configuration, and the air bag of loop configuration is placed in annular chamber.
The air bag is multiple, and multiple air bags are sequentially set along the circumferential direction of annular chamber, when each air bag pours compressed air
Two neighboring air bag mutually squeezes during to swelling state, and the shaft is equipped with the connecting tube connected with the gas nozzle on each air bag.
The idler wheel is two, and the outer diameter of two idler wheels is identical.
After more than structure, the guide roller of the backlight kludge of the utility model is compared with prior art with following excellent
Point：First, shaft when can reduce the diaphragm that shaft attaches on backlight module by the bulge on castor and castor
It is not easy to leave impression for the impact force of diaphragm, therefore on diaphragm, secondly, can be realized by the size for adjusting air pressure in air bag
Bulge size it is adjustable, finally, multiple bulges can realize the Multi-contact with diaphragm, therefore adhesive tape contact with diaphragm bottom
For Multi-contact, be conducive to tear.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
The utility model provides a kind of guide roller of backlight kludge, it includes shaft 1, in the shaft 1 vertically according to
Sequence is equipped with multiple idler wheels 2, it is characterised in that：A castor 3 is equipped between two idler wheels 2 of arbitrary neighborhood, in being equipped in castor 3
Heart through hole, the castor 3 are fixedly connected by central through hole with shaft 1, and the outer diameter of the castor 3 is less than or equal to idler wheel
2 outer diameter is equipped with an annular chamber in the castor 3, is equipped with an air bag 4 in annular chamber, on the lateral wall of the castor 3
It is even that several through holes are distributed with, when poured in air bag 4 air to air bag 4 lateral wall and annular chamber madial wall against when the gas
