Background technology
Comprehensively universal along with intelligent mobile phone, and the continuous innovation of technology, mobile phone products presents the feature such as renewal, cheapization, quality severization fast, and the competition of each large handset manufacturers is also growing more intense.In this context, price becomes the strong weapon defeated one's opponents undoubtedly.Thus, low cost becomes the problem that everybody more and more pays close attention to.Based on more than, cost pressure is also just distributed on the body of each mobile phone components supplying business.
Existing lamp bar and sticking double faced adhesive tape technique, first by sticking double faced adhesive tape on the glue frame and light guide plate of backlight, then by lamp bar taking off one by one from the arrangement of justifying, finally again lamp bar is pasted onto on double faced adhesive tape, with the glue frame of backlight, assembling light guiding plate to together with, but the process of this rubberizing, labor intensive is numerous, inefficiency.
Summary of the invention
Based on the technical problem that background technology exists, the present invention proposes a kind of lamp bar and double faced adhesive tape justifying method of attaching.
A kind of lamp bar that the present invention proposes and double faced adhesive tape justifying method of attaching, carried out the stickup of justifying lamp bar and justifying double faced adhesive tape, specifically comprise the following steps by justifying arrangement and contraposition punching press:
LED justifying is welded on FPC;
According to FPC profile cutting double faced adhesive tape assembly, obtain double faced adhesive tape plate, double faced adhesive tape assembly is by double faced adhesive tape and be pasted on first mould release membrance on the relative two sides of double faced adhesive tape respectively and the second mould release membrance forms;
On corresponding justifying FPC, hollow out process is carried out to the first mould release membrance on double faced adhesive tape plate in LED position;
By localization tool, double faced adhesive tape plate is pasted on justifying FPC with the first mould release membrance near the direction of justifying FPC;
The justifying FPC having attached double faced adhesive tape plate is carried out outline die by diel, obtains the LED being pasted with double faced adhesive tape and the second mould release membrance of justifying arrangement.
Preferably, positioning mark is one to one provided with on double faced adhesive tape plate with on justifying FPC.
Preferably, positioning mark is locating hole.
Preferably, the thickness of the first mould release membrance is not less than 0.1mm.
Preferably, the first mould release membrance and the second mould release membrance all adopt PET material to make.
Preferably, localization tool by the N number of boss be arranged on FPC and be arranged on double faced adhesive tape plate and with N number of boss one to one through hole form, N >=3.
In the present invention, by justifying arrangement and the die-cut stickup carrying out justifying lamp bar and justifying double faced adhesive tape of contraposition, achieve lamp bar and double faced adhesive tape Batch assemblage, substantially increase labeling rates, improve efficiency, reduce cost of labor.
In the present invention, LED justifying is arranged on FPC, and the first mould release membrance in double faced adhesive tape assembly carries out hollow out process with the arrangement mode of corresponding LED, when ensure that FPC and double faced adhesive tape plate are fitted, each LED all can paste on double faced adhesive tape through the first mould release membrance, ensures that each LED is with glue.
Accompanying drawing explanation
Fig. 1 is a kind of lamp bar of proposing of the present invention and double faced adhesive tape justifying method of attaching flow chart.
Detailed description of the invention
With reference to Fig. 1, a kind of lamp bar that the present invention proposes and double faced adhesive tape justifying method of attaching, by justifying arrangement and the die-cut stickup carrying out justifying lamp bar and justifying double faced adhesive tape of contraposition, achieve lamp bar and double faced adhesive tape Batch assemblage, substantially increase labeling rates.
The lamp bar that the present invention proposes and double faced adhesive tape justifying method of attaching specifically comprise the following steps:
Step one, LED justifying to be welded on FPC (Flexible Printed Circuit board, flexible print wiring board).
In this step, LED is justifying arrangement on FPC, for the justifying assembling of LED lays the foundation.
Step 2, according to FPC profile cutting double faced adhesive tape assembly, obtain double faced adhesive tape plate, double faced adhesive tape assembly is by double faced adhesive tape and be pasted on first mould release membrance on the relative two sides of double faced adhesive tape respectively and the second mould release membrance forms.
The existence of the first mould release membrance and the second mould release membrance avoids double faced adhesive tape and surprisingly pastes other materials and cause viscous force to decline.In present embodiment, the first mould release membrance and the second mould release membrance all adopt PET (polyethyleneterephthalate, PETG) material to make.
On step 3, corresponding justifying FPC, hollow out process is carried out to the first mould release membrance on double faced adhesive tape plate in LED position.
In this step, the first mould release membrance hollow out process can expose the two-sided gluing surface be entirely covered, thus lays the foundation for double faced adhesive tape adheres to LED.
In this step, the first mould release membrance carries out hollow out in the mode that trepanning is die-cut, and for avoiding first releasely lepthymenialy to cause die-cut transition, in present embodiment, the thickness of the first mould release membrance is not less than 0.1mm.
Step 4, by localization tool, double faced adhesive tape plate to be pasted on justifying FPC with the direction of the first mould release membrance near justifying FPC.
In this step, because the first mould release membrance of corresponding LED position is by hollow out, so when double faced adhesive tape plate and justifying FPC fit, each LED all and sticking double faced adhesive tape.
In present embodiment, positioning mark is one to one provided with on double faced adhesive tape plate with on justifying FPC, in this step, the accuracy that double faced adhesive tape plate and justifying FPC fit can be ensured by positioning mark, thus ensure the hollow out position of correct corresponding first mould release membrance of each LED, thus adhere to double faced adhesive tape.In present embodiment, positioning mark is locating hole.
In present embodiment, localization tool by the N number of boss be arranged on FPC and be arranged on double faced adhesive tape plate and with N number of boss one to one through hole form, determine the principle in face according to 3, N >=3.So, boss coordinates with through hole, can be fixed the laminating of justifying FPC and double faced adhesive tape plate, prevents skew.
Step 5, the justifying FPC having attached double faced adhesive tape plate is carried out outline die by diel, obtain the LED being pasted with double faced adhesive tape and the second mould release membrance of justifying arrangement.
In this step, by die-cut mode, cut off the part that double faced adhesive tape plate meta is pasted in LED, make each LED on FPC all be pasted with double faced adhesive tape and the second mould release membrance, and mutual adhesion between the double faced adhesive tape of different LED attaching.
This method is utilized to complete after LED and double faced adhesive tape justifying pastes, the LED be welded on one by one on FPC has all attached double faced adhesive tape and the second mould release membrance, after LED being taken off removing second mould release membrance, just the LED of band glue and light guide plate can be combined in advance, to guarantee that LED is close to light guide plate, make that light is as much as possible to be penetrated as conduit tabula rasa, and then load glue frame, promote the light utilization efficiency of LED.
The above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
