The utility model aim is achieved in that
A kind of back light module unit structure for automated production, key are: including backboard, reflector plate, light guide plate, lamp
The incident side of item, diaphragm and panel, the backboard forms in 90 ° of bendings and in the middle part of backboard accommodating space, and the reflector plate is led
Tabula rasa, diaphragm and panel are sequentially arranged at from the bottom up in the accommodating space of the backboard, the incident side edge of the light guide plate
There are gap and as mounting groove between the backboard bending part, the lamp bar includes substrate and the one side for being mounted on the substrate
And equally distributed lamp bead, for the substrate-parallel in backboard bottom surface, the lamp bead is towards the backboard bottom surface and is located at the peace
In tankage, the base plan of the lamp bead two sides passes through the bending part and guide-lighting edges of boards of lamp bar fixation adhesive tape and the backboard respectively
Portion is adhesively fixed, and the panel incident side edge is fixed with the substrate bonding.
Using the above structure, the lamp bead of lamp bar is arranged downward, is supported by substrate, can substitute the U of former backboard completely
Folding effect, backboard only need 90 ° of bendings to form accommodating space, and there are also substrates can equally play interception, original backboard U
Folding inside is inconvenient to process, and shading rubber belt can only be arranged, and the substrate surface in this structure is easy to process, and there is no need in substrate
Shading rubber belt is arranged in side directed downwardly；Most of all, the structure during installation can vertical back-panel be directly fixedly mounted, do not have
Corner difficult to install is suitable for positioning and installation in automatic production line.
Preferably, above-mentioned panel incident side edge is fixed by shading rubber belt and the substrate bonding.
Using the above structure, panel and lamp bar itself need adhesive tape to fix, and use shading rubber belt, then can further opposite
Bonding portion between plate and lamp bar carries out shading, not will increase adhesive tape and adhesive tape installation procedure, reduces product thickness, can
Realize that product is thinner.
Preferably, above-mentioned shading rubber belt extends the substrate towards the side in the middle part of backboard and glues with the diaphragm edge
It connects.
Using the above structure, shading rubber belt can solve the leakage problem between diaphragm and substrate.
Preferably, the incident side edge of above-mentioned reflector plate extends to the corner of the backboard bending part.
Using the above structure, reflector plate is wider to the receiving plane of light source, can play the role of certain blast.
Preferably, the upper surface of above-mentioned light guide plate is coplanar with the top edge of the backboard bending part.
Using the above structure, it is ensured that the depth of parallelism of substrate installation further increases the precision of installation.
Preferably, the aforesaid substrate place face Nian Jie with light guide plate is equipped with white coating, and the jointing tape of the adhesive portion is
Adhesive tape.
Using the above structure, increase white coating on substrate, the reflection to light can be further enhanced, enhance the effect of shading
Fruit, it is not necessary that shading rubber belt is arranged in the face, to reduce installation difficulty and reduce product thickness.
The utility model has the advantages that
A kind of back light module unit structure for automated production of the utility model, guarantee structural strength and incident side function
In the case of, it still can be suitably used for automatic assembling production line, improve product installation accuracy, meet the market demand, product is able to achieve more
It is thin.
