By using the method provided by the invention, the shell and the protective panel can be extremely easily disassembled, the protective panel is difficult to damage, the perfectness is increased from original 25 percent to 100 percent, the reutilization rate of the shell is increased, and the use cost, the maintenance cost and the production cost are reduced.
Description
Technical field
The present invention relates to a kind of disassembling method that has the contact panel of package shell, belong to electronic product display screen technology field.
Background technology
The many electronic product imperative equipment of contact panel can be play multiple information such as picture that literal, video ads, FLASH and computer play and vision signal.When the finger touches screen; Have analog signal output; Convert analog signal into computing machine acceptable digital signal by controller; Integrate each assembly compiling via the touch-control driver in the computing machine again, on screen, demonstrate the position of being touched by display card output screen signal at last, flexible and convenient to use.But contact panel is an induction type precise electronic assembly simultaneously; Can not use sharp-pointed article on contact panel, to write; Also can not weight use or percussion, do not cause damage by meeting, its aging speed wants fast a lot of with respect to other parts of electronic product in addition; So, also be very high for the repair rate of contact panel.
Generally contact panel comprises the protection panel that is attached at outer surface of outer cover and is attached at the sensor layer of protecting panel, and protection panel and sensor layer also join through glue.The protection panel generally adopts the tempered glass material, and shell is magnalium or rigid plastic.
Usually the contact panel damage is because its inner sensor layer is malfunctioning; Can not normal running, or the protection panel suffers damage, when waste and old machine is recycled when it being changed maintenance; Need to protect panel and sensor layer and shell folding to separate and come, shell can utilize again.Existing disassembling method is directly to utilize instrument will protect panel and sensor layer to pull down from shell; This quadrat method is not only required great effort, and rolls over and separate the breakage easily of back protection panel, and serviceability rate has only about 25%; Most shell can not continue to have used again, causes in a large number and scraps.
Summary of the invention
Technical matters to be solved by this invention is protection panel and the process of sensor layer under shell is disassembled with contact panel; How to improve the utilization factor again of shell; Especially for the shell of magnalium, reduce use, maintenance and production cost.
The technical matters that the present invention further solves be the case surface that guarantees to pull down protection panel and sensor layer be smooth, clean.
For solving the problems of the technologies described above; The present invention provides a kind of disassembling method that has the contact panel of package shell; Contact panel comprises shell, protection panel, sensor layer first glue layer and second glue layer, first glue layer be used to fit shell and protection panel, and protection panel and sensor layer join by the stickup of second glue layer; It is characterized in that, may further comprise the steps:
1) iron plate is heated to 110 ℃-150 ℃;
The protection panel that 2) will have a contact panel of package shell is placed towards the iron plate hot face and is begun heating, and be 30-60 second heat time heating time;
3) contact panel is taken off from iron plate, stop heating, will protect panel and sensor layer to take off from shell gently and get final product.
The aforesaid disassembling method that has the contact panel of package shell is characterized in that: in said step 1), the iron plate heating-up temperature is 130 ℃.
The aforesaid disassembling method that has the contact panel of package shell is characterized in that: in said step 1), be 40 seconds heat time heating time.
The aforesaid disassembling method that has the contact panel of package shell is characterized in that, and is further comprising the steps of: utilize detersive that protection panel and shell bonding place are cleaned, said detersive is the potpourri of positive methylheptane and positive methylpentane.
The beneficial effect that reaches of the present invention:
The disassembling method that has the contact panel of package shell of the present invention utilizes the characteristic of the glue layer between shell and the protection panel in heating process, can soften, and glue layer viscosity reduces ineffective; Protection panel and shell are disassembled easily come, utilize method of the present invention, shell is easy to disassemble with the protection panel and comes; And the protection panel is difficult for damaged; Serviceability rate rises to 100% by original 25%, improves the utilization factor again of shell, reduces use, maintenance and production cost.

Embodiment
Be example with the mobile phone below, method of the present invention be further described in conjunction with accompanying drawing.
Fig. 1 is the front elevation that has the contact panel of package shell of the present invention, and Fig. 2 is the rear view that has the contact panel of package shell, and Fig. 3 is that A-A among Fig. 1 is to cut-open view.See also Fig. 3, contact panel 10 comprises shell (frame) 1, protection panel (cover lens) 2, sensor layer (sensor layer) 3 first glue layer 4 and second glue layer 5.First glue layer 4 be used to fit shell 1 and protection panel 2, protection panel 2 is pasted by second glue layer 5 with sensor layer 3 and is joined.Shell 1 can be magnalium or rigid plastic.The protection panel 2 general tempered glass material that adopt have active region (active area) 6 and ink area (black matrix) 7, and stretch out the inside casing line X of shell 1, as shown in Figure 3.Sensor layer 3 can be indium tin oxide transparent conductive materials such as (indium tin oxide), in Fig. 1 and Fig. 2, is represented by dotted lines, and does not stretch out the inside casing line X of shell 1.A first adhesive layer 4 is generally used optically transparent adhesive (optical? Clear? Adhesive,? OCA)?, And the protective panel 2 overlap region 7 of the ink.Second glue layer 5 can be glue, with the active region 6 and/or ink area 7 overlappings of protection panel 2.
The disassembling method that has the contact panel 10 of package shell 1 of the present invention may further comprise the steps:
1) iron plate 8 is heated to 110 ℃-150 ℃; Heating-up temperature need be controlled in the scope that shell 1, protection panel 2, sensor layer 3 and second glue layer 5 can bear; But it is outside the scope that first glue layer 4 can be born, proper when generally being controlled at 130 ℃ of left and right sides;
The protection panel 2 that 2) will have a contact panel of package shell 1 is placed towards the iron plate hot face and is begun heating, and be 30-60 second heat time heating time, and be controlled at about 40 seconds general heat time heating time, as shown in Figure 4;
3) contact panel is taken off from iron plate, stop heating, will protect panel 2 and sensor layer 3 to take off from shell 1 gently and get final product, Fig. 5 is the synoptic diagram of the contact panel after disassembling.
Level totally with the adhesive residue of first glue layer 4 of protection panel 2 bonding places in order to make the shell 1 after disassembling; Further comprising the steps of: utilize detersive will protect panel 2 and shell 1 bonding place to clean, said detersive is the potpourri of positive methylheptane and positive methylpentane.Positive methylheptane and positive methylpentane are the key component of common detergents, can both play the effect of cleaning, and two weight percentages of components all can realize the object of the invention between 0-100%.Tool or the instrument that in addition, can also use other are (for example: setline), cut second glue layer 5, and separated with sensor layer 3 will protect panel 2.
Utilize method of the present invention to carry out tear down operations, operating result shows that disassemble serviceability rate rises to 100% by original 25%.
Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replacement or the technical scheme that obtained of equivalent transformation mode, all drop within protection scope of the present invention.
