Through adopting groined type guiding groove formula design, the glue dissolving liquid such as guide alcohol is in first guiding groove 210, second guiding groove 220, third guiding groove 230, fourth guiding groove 240 with in the time of the inside flow of fifth guiding groove 270, reduce battery gum layer 100's viscosity reaches the purpose that the battery was dismantled, and 0.03mm can be accomplished to this kind of gum thickness minimum, and process above-mentioned process dismantlement battery gum layer 100 can not damaged, can reuse, and cost of maintenance is lower when leading to the mobile terminal body to damage, and because battery gum structure simple structure also can reduce mobile terminal's manufacturing cost simultaneously.

As shown in fig. 2, in the specific embodiment of the present invention, an open slot 310 is formed on the middle frame 300, and the open slot 310 is communicated with the second inlet slot 280. The open slot 310 is a square slot, the open slot 310 not only can make the mobile terminal body do the water that IPX2 is experimental follow the open slot 310 flows out, further flows into the gum structure the second inlet slot 280, and then follows the export groove 260 flows out the gum structure has guaranteed that the inside device of mobile terminal does not receive the infringement of liquid, can also make the circuit of battery passes the open slot 310 inserts mobile terminal's screen end, does mobile terminal's screen power supply.

Example four

On the basis of the first embodiment, the second embodiment and the third embodiment of the present invention, as shown in fig. 3, the present invention further provides a battery disassembling method applied to the mobile terminal according to the third embodiment, which includes the specific steps of:

and S100, dripping a degumming solution into the opening of the flow guide part.

When the glue dissolving device is specifically implemented, the glue dissolving liquid is dripped into the opening of the first inlet groove, so that the glue dissolving liquid enters the battery back glue layer through the opening of the first inlet groove, the glue dissolving liquid can be specifically an alcohol solution, and the glue dissolving liquid has the function of reducing the viscosity of the battery back glue layer.

And S200, waiting for preset time to enable the peptizing solution to flow along the guide grooves in the flow guide part and penetrate through the battery back glue layer.

When the device is specifically implemented, after the degumming solution enters the battery back glue layer through the opening of the first inlet groove, the degumming solution flows along a plurality of guide grooves in the flow guide part, namely the first guide groove, the second guide groove, the third guide groove and the fourth guide groove are in the middle of the battery back glue layer to form a groined structure and flow, so that the battery back glue layer is continuously permeated.

And step S300, waiting for the redundant degumming liquid to flow out along the diversion part.

When the mobile terminal is specifically implemented, work as the solution glue is in a plurality of in the water conservancy diversion portion after the guiding groove flows and accomplishes, it is unnecessary the solution glue along the export groove flows out, has not only reached and has reduced the viscidity purpose of battery gum layer, has still protected battery gum structure is not destroyed, has reduced unnecessary the solution glue is in the inside residue of mobile terminal body, has protected the inside components and parts of mobile terminal not receive the destruction of liquid.

And step S400, disassembling the battery.

When the method is used for disassembling the battery in specific implementation, the battery gum structure and the battery can be guaranteed not to be damaged, the battery can be repeatedly used, and the cost is reduced.

In summary, the battery back adhesive layer 100 for fixing the battery on the mobile terminal body and the diversion parts 200 which are arranged on the battery back adhesive layer 100 in a staggered manner to form the flow channels are arranged, so that the debonding liquid flows through the flow channels and permeates into the battery back adhesive layer 100 more uniformly, the viscosity of the battery back adhesive layer 100 is reduced, the purpose of detaching the battery is achieved, and the problems that the back adhesive structure is easy to damage and cannot be reused in the process of detaching the battery of the mobile terminal body are solved.

It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
