Referring to fig. 1 and 2, the mobile terminal 100 includes a graphite sheet 1, an adhesive 2 and components, wherein the mobile terminal 100 according to the embodiment of the present invention may be any device with communication and storage functions, for example: the system comprises intelligent equipment with a network function, such as a tablet computer, a mobile phone, an electronic reader, a remote controller, a Personal Computer (PC), a notebook computer, vehicle-mounted equipment, a network television, wearable equipment and the like.
In this embodiment, referring to fig. 3, the graphite sheet 1 is adhered to the device through the adhesive 2, and the exhaust channel 12 is used for exhausting bubbles 4 generated by adhering the graphite sheet 1 to the device; graphite flake 1 includes body 11 and at least one exhaust passage 12, body 11 has the face of bonding 11a, at least one exhaust passage 12 arrange in on the face of bonding 11a of body 11, just at least one exhaust passage 12 runs through body 11, exhaust passage 12 includes two long limit L1 of relative setting and two short sides L2 of relative setting, two short sides L2 connect respectively in between two long limit L1, the length of short side L2 is less than the length of long limit L1.
By providing the exhaust passage 12 on the body 11 of the graphite sheet 1, the air bubbles 4 generated during the mounting process of the graphite sheet 1 can be better exhausted from the exhaust passage 12.
Specifically, referring to fig. 3, the graphite sheet 1 includes a body 11 and an exhaust passage 12. The body 11 has an adhesive surface 11a and a back surface 11b which are opposite to each other, and the body 11 is adhered to the device through the adhesive surface 11 a. Therefore, the exhaust channel 12 is arranged on the bonding surface 11a of the graphite sheet 1, so that the exhaust channel 12 can conveniently discharge the bubbles 4 on the bonding surface 11a through the exhaust channel 12, the phenomenon that the body 11 and a device are loosened due to the bubbles 4 on the bonding surface 11a is avoided, and the reliability of the graphite sheet 1 is improved.
Referring to fig. 3, the exhaust passage 12 includes two opposite long sides L1 and two opposite short sides L2, the two short sides L2 are respectively connected between the two long sides L1, and the length of the short side L2 is smaller than that of the long side L1. The inventor finds that when the mounting between the graphite sheet 1 and the device is not uniform, the air bubbles 4 are randomly generated between the graphite sheet 1 and the device, even if the back surface 11b of the body 11 is uniformly pressed, because the viscose 2 used for adhering the graphite sheet 1 and the device is relatively sticky and can influence the movement of the air bubbles 4, the air bubbles 4 far away from the edge of the graphite sheet 1 are difficult to move out of the graphite sheet 1, the inventor designs various exhaust channels 12, and after comparing the various exhaust channels 12, the inventor finds that the air bubbles 4 can be better pressed into the exhaust channels 12 by arranging the exhaust channels 12 in a long and narrow slit shape. The specific exhaust principle of the exhaust passage 12 is as follows: firstly, referring to fig. 3, as the weight of the air bubbles 4 is greater than the viscosity of the adhesive 2, once the air bubbles 4 move to the air discharge passage 12, the air bubbles 4 immediately drop into the air discharge passage 12, and the air bubbles 4 are discharged from the bonding surface 11a of the main body 11; secondly, referring to fig. 4, since the weight of the bubble 4 is less than the viscosity of the adhesive 2, even if the bubble 4 moves to the air discharge passage 12, the bubble 4 will not be immediately discharged from the air discharge passage 12 due to the adhesiveness between the surrounding adhesive 2 and itself, but as the bubble 4 moves slowly on the air discharge passage 12 with the gradual pressing, the movement of the bubble 4 will reduce the adhesiveness between the bubble 4 and the surrounding adhesive 2, and finally will fall into the air discharge passage 12, so as to discharge the bubble 4.
As can be understood, the slit width of the exhaust passage 12 is 0.01 to 0.1 mm. The smaller the slit width of exhaust passage 12, the less graphite is cut off, and the smaller the influence on the heat conduction and heat dissipation performance of graphite sheet 1.
In one embodiment, referring to fig. 5, the number of the exhaust passages 12 is two, one exhaust passage 12 extends along the length direction Y of the bonding surface 11a, the other exhaust passage 12 extends along the width direction X of the bonding surface 11a, and the two exhaust passages 12 have an intersection.
It will be appreciated that another one of said exhaust passages 12 spans one of said exhaust passages 12. The intersection of the two discharge channels 12 is at the center of each other and has a cross shape, and the cross-shaped discharge channels 12 divide the air bubbles 4 into four regions D1, ensuring the air bubbles 4 in these four regions D1. Ensure that the air bubbles 4 in each area can be close to the two-directional parts of the exhaust passage 12, and can exhaust partial air bubbles 4 and even all air bubbles 4 as much as possible. Of course, in other embodiments, the two exhaust passages 12 may also be L-shaped, T-shaped, etc.
Specifically, two exhaust passage 12 arrange along the length direction Y and the width direction X of bonding face 11a respectively, and this exhaust passage 12's arrangement structure guarantees that when pressing graphite flake 1 along graphite flake 1's each direction, guarantees that bubble 4 on the graphite flake 1 is stronger from exhaust passage 12, and the bubble 4 of being convenient for falls into exhaust passage 12, more does benefit to the exhaust.
When there are air bubbles 4 in the width direction X of the bonding surface 11a (at this time, the worker does not know that there are air bubbles 4 in the width direction X), the worker may first press the graphite sheet 1 along the length direction Y of the bonding surface 11a, and the air bubbles 4 farther from the length direction Y on the bonding surface 11a move in the length direction Y along with the pressing, and at this time, the air bubbles 4 may fall into the exhaust passage 12 by moving to the exhaust passage 12 located in the width direction X at this time, and the other one is farther from the exhaust passage 12 located in the width direction X and cannot fall into the exhaust passage 12. In the latter case, after the worker presses the graphite sheet 1 along the longitudinal direction Y of the adhesion surface 11a, the air bubbles 4 move in the width direction X along with the pressing, and gradually move to the air bubbles 4 located in the longitudinal direction Y, thereby discharging the air bubbles 4.
In another embodiment, referring to fig. 6, the number of the exhaust channels 12 is several, the extending directions of the several exhaust channels 12 on the bonding surface 11a are the same, and the several exhaust channels 12 are uniformly arranged at intervals.
Specifically, the graphite sheet 1 is similar to a T-shaped structure, six exhaust channels 12 are provided, the six exhaust channels 12 are all arranged along the length direction Y of the bonding surface 11a, the four exhaust channels 12 are located in the wider region Z1 of the graphite sheet 1, the two exhaust channels 12 are located in the narrower region Z2 of the graphite sheet 1, and the arrangement of the exhaust channels 12 ensures that most or all of the bubbles 4 can be discharged. Of course, in other embodiments, the exhaust passages 12 may be four, eight, etc.
Further, referring to fig. 2, the edge of the air discharge channel 12 on the bonding surface 11a is provided with a round 11a, and the opening of the air discharge channel 12 is provided with the round 11a, so that the air bubbles 4 can slide off from the opening of the air discharge channel 12 more easily, and the air bubbles 4 can be discharged conveniently.
Specifically, the cutter edge of the die-cutting rule is provided with a round 11a structure, so that the opening of the processed exhaust passage 12 is the round 11a, the air bubble 4 can slide from the opening of the exhaust passage 12 more easily, and the air bubble 4 can be discharged conveniently.
When the mobile terminal 100 provided by the embodiment of the present invention is installed, firstly, the adhesive 2 is disposed on the adhesive surface 11a of the body 11; then the body 11 is glued on the component; next, graphite sheet 1 is pressed so that air bubbles 4 generated by sticking of graphite sheet 1 to the device are discharged from said exhaust passage 12. According to the mobile terminal 100 provided by the embodiment of the invention, the exhaust channel 12 is arranged on the body 11 of the graphite sheet 1, so that the air bubbles 4 generated in the mounting process of the graphite sheet 1 can be better exhausted from the exhaust channel 12.
The method for mounting a graphite sheet according to an embodiment of the present invention will be described in detail with reference to fig. 7.
It should be noted that the graphite sheet 1 in the mobile terminal 100 shown in fig. 2 is manufactured by the method of the embodiment shown in fig. 7 of the present invention. For the specific structure of the present embodiment, please refer to the embodiments shown in fig. 1 to 6, which are not described herein again.
Fig. 7 is a schematic flow chart illustrating a method for mounting a graphite sheet according to an embodiment of the present invention. As shown in fig. 7, the method of the embodiment of the present invention may include the following steps S101 to S103.
S101: at least one exhaust channel is machined on the bonding surface of the graphite sheet.
S103: and adhering the graphite sheet with the adhesive on the adhering surface on a device, and uniformly pressing the graphite sheet to discharge bubbles generated by adhering the graphite sheet and the device from the exhaust channel.
Specifically, the graphite sheet includes a body and an exhaust channel. The body has the face of bonding and the back of the body setting of carrying on the back mutually, and the body bonds on the device through the face of bonding. The event is seted up exhaust passage on the face of bonding of graphite flake to the bubble that exhaust passage will bond on the face discharges through exhaust passage, avoids taking place to loosen between body and the device because of the bubble on the face of bonding, improves the reliability of graphite flake.
Wherein, exhaust passage includes two relative long limits that set up and two relative minor faces that set up, two minor faces connect respectively in between two long limits, the length of minor face is less than the length on long limit. The inventor finds that when the pasting between the graphite sheet and the device is uneven, the air bubbles are randomly generated between the graphite sheet and the device, even if the back of the body is uniformly pressed, because the viscose used for adhering the graphite sheet and the device is relatively sticky and can influence the movement of the air bubbles, the air bubbles far away from the edge of the graphite sheet are difficult to move out of the graphite sheet, the inventor designs various exhaust channels, and after comparing the various exhaust channels, the inventor finds that the exhaust channels are arranged into long and narrow slit shapes, and the air bubbles can be better pressed into the exhaust channels. The specific exhaust principle of the exhaust passage is as follows: firstly, as the weight of the air bubbles is greater than the viscosity of the viscose, the air bubbles immediately fall into the exhaust channel as soon as the air bubbles move to the exhaust channel, so that the air bubbles are discharged from the bonding surface of the body; secondly, because the weight of bubble is less than the viscidity of viscose, even then the bubble removes on the exhaust passage, the bubble is because the viscose and the cohesiveness of self around, and it can not discharge from the exhaust passage immediately, nevertheless along with gradually pressing, the bubble can be slow removal on the exhaust passage, and the removal of bubble can reduce its and the cohesiveness of viscose around, still can fall into the exhaust passage finally, realizes the discharge of bubble.
It will be appreciated that at least one vent passage is machined through the die cutter. Specifically, the graphite flake is placed below the die-cutting rule, and the die-cutting rule penetrates through the graphite flake, so that an exhaust channel with a slit width of 0.01-0.1 mm, namely a very small slit width, can be processed. The smaller the slit width of the exhaust passage, the less the graphite is cut off, and the smaller the influence on the heat conduction and heat dissipation performance of the graphite sheet is.
It can be understood that the number of the cutting knives and the cutting sequence of the cutting knives are determined according to the arrangement of the exhaust channels on the graphite sheet.
In one embodiment, the number of the exhaust passages is two, one of the exhaust passages extends along the length direction of the bonding surface, the other exhaust passage extends along the width direction of the bonding surface, and the two exhaust passages have an intersection.
In another embodiment, the number of the exhaust channels is several, the extending directions of the several exhaust channels on the bonding surface are the same, and the several exhaust channels are arranged at equal intervals.
According to the mounting method of the graphite sheet, provided by the invention, the exhaust channel is arranged on the body of the graphite sheet, so that air bubbles generated in the mounting process of the graphite sheet can be better exhausted from the exhaust channel.
The modules or units of the embodiments of the present invention can be combined or separated according to actual requirements.
