Abstract
The split type square shape plastic structure of backlight module, comprise pair of parallel and spaced connecing draws limit and pair of parallel and spaced enclosed edge, the described side of drawing limit that connects protrudes out two teats, and two teat intervals are arranged, described in connect and draw limit and be oppositely arranged with teat; Described enclosed edge is arranged on two with the corresponding described teat in both ends and connects and draw between limit; Described pair of parallel and spaced connecing is drawn limit and pair of parallel and spaced enclosed edge and is enclosed and form square shape structure.The utility model is by point body position on adjustment mouth word glue four limit, and to reach the object of the material saved in mouth word, and processing technology is simple, and dimensional accuracy is high and stable.
Description
Technical field
The utility model relates to the split type square shape plastic structure of a kind of backlight module, the black glue of split type square shape, black white glue structure particularly on the display device backlight module such as a kind of mobile phone, panel computer, Vehicular display device.
Background technology
The backlight module of the display device such as existing mobile phone, panel computer, Vehicular display device all can use black glue or black and white glue usually, in order to optical material, structural member, liquid crystal panel etc. to be fixed together, and play effects such as covering marginal ray simultaneously.Because viewing area needs sky to open, so black glue or black and white glue are all approximate square shape shape usually, be also commonly called as a mouthful word glue.Existing black glue or black and white glue have two kinds usually, 1, see shown in accompanying drawing 1, mouth word glue four limit is one-body molded, add man-hour the material in mouth word glue to be emptied and abandon, the shortcoming of this structure is: a large amount of expensive black glue or black and white glue material cause waste owing to giving it up, and the increase of the size along with display device, waste of material is further serious.2, see shown in accompanying drawing 2 and accompanying drawing 3, the four edges of mouth word glue is split type, and the both sides of an opposite side have breach, and the end of another opposite side is goed deep into being formed square shape structure to enclose in breach.The method of square shape shaping structures is: by a pair edge forming jaggy for tool, namely parallel and be spaced, distance between this opposite side is also correspondingly accurately determined, and then another two limits being fixed at twice the end on tool two limits jaggy, the advantage of this structure saves black glue in mouth word glue or black and white glue material.Shortcoming is complex process, can accurately determine in the spacing adding front two limits in man-hour (tool two limits jaggy), the fixing means on rear two limits is: to be shifted on rear two limits by asynchronous laminating (realizing laminating spacing by front and back drum speed difference) function and to be fixed to and the relative position determined, front two limits, be difficult to the stable high precision ensureing rear two limit spacing by such manner, thus cause product height fraction defective.
Summary of the invention
The utility model provides a kind of backlight module split type square shape plastic structure.
For achieving the above object, the technical solution adopted in the utility model is: the split type black glue of a kind of backlight module, black white glue structure, comprise pair of parallel and spaced connecing draws limit and pair of parallel and spaced enclosed edge, the described side of drawing limit that connects protrudes out two teats, and two teat intervals are arranged, described in connect and draw limit and be oppositely arranged with teat; Described enclosed edge is arranged on two with the corresponding described teat in both ends and connects and draw between limit; Described pair of parallel and spaced connecing is drawn limit and pair of parallel and spaced enclosed edge and is enclosed and form square shape structure.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model is by point body position on adjustment mouth word glue four limit, and to reach the object of the material saved in mouth word, and processing technology is simple, and dimensional accuracy is high and stable.
Accompanying drawing explanation
Accompanying drawing 1 is four limit one-body molded mouth word plastic structures.
Accompanying drawing 2 is prior art four limit split type mouth word plastic structure.
Accompanying drawing 3 is the A portion enlarged drawing of accompanying drawing 2.
Accompanying drawing 4 is embodiment one schematic diagram.
Accompanying drawing 5 is the B portion enlarged drawing of accompanying drawing 4.
Accompanying drawing 6 is embodiment two schematic diagram.
Accompanying drawing 7 is the c portion enlarged drawing of accompanying drawing 6.
Accompanying drawing 8 is die cutting method schematic diagram.
In above accompanying drawing: 1, connect and draw limit; 2, teat; 3, enclosed edge; 4, cross cutting limit.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one: the split type square shape plastic structure of backlight module
Shown in accompanying drawing 4, accompanying drawing 5 and accompanying drawing 8, the split type black glue of backlight module, black white glue structure, the present embodiment is for black glue, it comprises pair of parallel and spaced connecing draws limit 1 and pair of parallel and spaced enclosed edge 3, the described side of drawing limit 1 that connects protrudes out two teats 2, and two teat 2 intervals are arranged, described in connect and draw limit 1 and be oppositely arranged with teat 2; Described enclosed edge 3 is arranged on two with the corresponding described teat 2 in both ends and connects and draw between limit 1; Described pair of parallel and spaced connecing is drawn limit 1 and pair of parallel and spaced enclosed edge 3 and is enclosed and form square shape structure.
Method for making: first correspondence connects the black glue that the length cross cutting drawing limit 1 and enclosed edge 3 obtains four strips, then the black glue of four strips is enclosed and form square shape (asynchronous cross cutting laminating is formed), now generally there is deviation between the distance of the black glue of strip facing each other and the distance of design, next cross cutting one cross cutting limit 4 on the black glue of four strips enclosing square shape, now remove a part of black glue material at the middle part cross cutting of the black glue of a pair strip and form teat 2, this is to connect to the black glue of strip and draws limit 1, another is enclosed edge 3 to the black glue that a whole lateral edges is cut a pair strip of flash trimming.Amount due to cross cutting is controlled, even if therefore there is deviation when enclosing the black glue of four strips, also can make to connect the spacing of drawing between spacing between limit 1, enclosed edge 3 accurately determine when cross cutting.
Embodiment two: the split type square shape plastic structure of backlight module
Shown in accompanying drawing 6 and accompanying drawing 7, the difference of this structure and embodiment one is that long limit and minor face exchange.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
