The present invention relates to a manufacturing method and a manufacturing apparatus for a heat dissipation sheet, and more specifically, to improve the heat transfer rate of the heat dissipation sheet by efficiently exhausting air contained in the working fluid of the heat dissipation sheet used in a portable terminal and closing the inlet. It relates to a manufacturing method and a manufacturing apparatus for a heat dissipation sheet, characterized in that it is configured to enable automation of the exhaust and finishing operations.

In general, in a portable terminal such as a smart phone or a tablet PC, heat is a fatal phenomenon that causes a malfunction, and smooth heat dissipation must be preceded. To this end, the portable terminal is configured to intersect the heat dissipation sheet 10 made of a metallic material between the circuit board and the display panel, so that heat generated therein can be efficiently discharged to the outside.

Is protruding. In this state, since the welding portions 15 welded linearly along the rims of the two side plates are formed, an accommodating space is formed inside. And the working space (F) such as distilled water is filled in the receiving space.

Therefore, the heat dissipation sheet 10 is mounted inside the portable terminal and a heating pipe is connected to the neck 13. When the portable terminal is used in this state, heat is generated inside, and the heat is transferred to the working fluid F through the plate 11, and the working fluid F is caused by convection. Since it moves to the neck 13, heat is radiated to the heating pipe. The heating pipe is also filled with a working fluid (F) therein to release heat to the outside.

The heat dissipation sheet 10 had the following problems.

In general, when processing a welding portion, the neck is made to open the E portion of FIG. 1 so that an inlet is formed. Then, after the working fluid 9F) is injected through the inlet, the E part is welded to be closed. However, air is introduced into the working fluid (F) due to this operation, and thus air bubbles are generated. Since this air has an insulating function, it is a major obstacle to heat transfer. In general, a portable terminal manufacturer is stipulating that the inside of the heat dissipation sheet 10 is a vacuum. So far, the technology to close the entrance so that the inside of the heat dissipation sheet 10 is in a vacuum state has not been suggested.

(Production method of heat-resistant sheet)

Figure 4 shows a method of manufacturing a heat dissipation sheet according to the present invention, (a) shows a heating step, (b) is a process diagram showing a finishing step, and FIG. 5 shows the manufacturing of the heat dissipation sheet according to the present invention. It will be described together as a perspective view showing that the entrance of the heat dissipation sheet by the method.

In general, a portable terminal such as a smart phone or a tablet PC is equipped with a heat dissipation sheet 10 inside, so that heat generated by the device can be quickly discharged. The heat dissipation sheet 10 is composed of a metal material such as copper or aluminum, and as shown in FIG. 4, two plates 11 are supported, and the plate 11 has a plate-shaped neck 13 protruding from the upper side. In this state, since the welding portions 15 welded linearly along the rim of the two side plates 11 are formed, the receiving space is formed inside while the two side plates 11 are attached. And the receiving space is filled with a working fluid such as distilled water. The welding portions 15 are formed in succession on both sides of the neck 13 so that the inlets must be formed so as to inject the working fluid to the outside, so that the welding portions 15 on both sides are not connected. That is, as shown in Fig. 4 (a), the welding portion 15 is not formed in the tip portion G of the neck 13.

In the present invention, it is characterized in that it is possible to improve the thermal conductivity by closing the tip portion (G) in a vacuum state by evacuating the air introduced into the heat dissipation sheet (10).

To this end, the method of manufacturing the heat dissipation sheet according to the present invention comprises the following steps.

1. Heating step;

Since the working fluid is vaporized by heating the heat dissipation sheet 10, air inside the heat dissipation sheet 10 is exhausted to the inlet. As an embodiment for this purpose, as shown in FIG. 4(a), blocks 430 are brought into close contact with both sides of the heat dissipation sheet 10. At this time, since the heat dissipation sheet 10 is in a standing state, the neck 13 is directed upwards so that the working fluid charged therein is not lost. At this time, the block 430 on both sides is a metal material with an electric heater (not shown) selectively mounted therein to heat the working fluid to become a gas. At this time, the heating time and temperature may be allowed to be detached from the heat dissipation sheet 10 after the block 430 is closely adhered to 160°C to 180°C for 2 to 4 seconds when the working fluid is distilled water and 0.2cc to 0.6cc. The block 430 may be kept in close contact until the finishing step is completed. Therefore, since the working fluid contained therein is vaporized and exhausted to the inlet, the air introduced therein is also pushed out. At this time, excessive pressure is applied to prevent exhaustion of the vaporized working fluid.

2. Closing stage;

After the heating step, that is, a finishing step of closing the entrance 2 to 4 seconds after the heating is started is performed. As an example, as shown in FIG. 4(b), the front end G of the neck 13 is linear. As the pressure is applied to conduct electricity, the welding portions 15 on both sides lead to another linear welding portion E, so that the inlet is closed. 15 shows an example in which the inlet is closed by the welding portion E. To this end, since the short axis 520 is pressed to both sides of the neck 13 and any one of the short axes 520 is formed with a linear blade 530, the welding portion E can be formed. That is, when the shortening 520 on both sides is made of copper and the DC power is conducted to both sides, current passes through the neck 13 through the blade 530 and then conducts to the shortening 520 on the other side. Therefore, since the electrical resistance heat is generated in the neck 13, the necks 13 on both sides are welded to close the inlet. As an example, when the thickness of the neck 13 is 0.3 mm to 0.7 mm and is copper, it is pressurized with a force of 3 kg to 5 kg at a temperature of 450° C. to 500° C. for 1 second to 2 seconds, and then the minor axis 520 on both sides is removed. Welding is completed.

And it is mounted on the upper surface of the table 100 to be interposed between the frame 200, the neck 13 is holding the heat dissipation sheet 10 so that the upward facing the frame in front of the frame 200 Loading unit 300 for transferring between the 200 is configured. And the heating unit 400 is mounted to correspond to the frame 200 on both sides, and is in close contact with both sides of the heat dissipation sheet 10 transferred by the loading unit 300 to perform a heating function. In addition, it is mounted to correspond to the frame 200 on both sides so as to be disposed on the upper portion of the heating unit 400, and presses the neck 13 on both sides to conduct electricity, so that the entrance is closed by electric resistance heat. A welding unit (500) is configured.

The embodiment of the heating unit 400 will be described with reference to FIGS. 6 and 7 as follows.

As being mounted to the frames 200 on both sides, the actuators 410 having the rods 411 facing each other and reciprocating are configured. As an example, the cylinders may be configured as air cylinders. In addition, blocks 430 facing the heat dissipation sheet 10 are mounted on the rods 411 on both sides, and are preferably formed of a metal material having excellent thermal conductivity. As an example, it is preferably formed of copper or aluminum. In addition, an electric heater (not shown) that is selectively mounted among the blocks 430 is configured. That is, the electric heaters may be built in both blocks 430 on both sides or may be mounted on only one side. As an example to be mounted, a hole may be perforated in the block 430 and a heater may be built in the hole, or may be attached to the outer surface of the block 430.

The embodiment of the welding unit 500 will be described with reference to FIGS. 6 and 7 as follows.

As each mounted on the frame 200 on both sides, an actuator 510 in which the rods 513 are opposed to each other to reciprocate is configured. As an example, it may be configured as an air cylinder, or may be composed of a linear motor capable of linear reciprocation. have. In addition, it is mounted on the rods 513 on both sides, and a short axis 520 facing the neck 13 is constructed, and is formed of copper to allow electric conduction. And the blade 530 is formed on either side of the short axis 520 on both sides to linearly press the neck (13). Therefore, since direct current power is connected to the short axis 520 on one side and the short side 520 on the other side, electrical resistance heat is generated when the neck 13 is pressed, so that the necks 13 on both sides are welded and attached to each other. It is configured to be closed.

Hereinafter, a detailed embodiment of the loading unit 300 together with the accompanying drawings will be described.

FIG. 8 is a side view showing only the loading unit separately from FIG. 7, and FIG. 9 is a perspective view showing that the arm is opened in a holder mounted to the loading unit shown in FIG. 8, and FIG. 10 is a frame in FIG. 9 A perspective view showing a state in which the heat dissipation sheet is in close contact, and FIG. 11 is a perspective view showing that the arm is closed in FIG. 10, and FIG. 12 is another embodiment of a holder constituting the present invention. It will be described together as a perspective view showing what has been made.

8, a rail 301 is disposed between the frames 200 on both sides and mounted in the front and rear directions, and a guider 303 is mounted on the rail 301 to be transportable, and the guider 303 The bracket 320 is mounted on. In addition, an actuator 310 connected to the bracket 320 and fixed to the upper surface of the table 100 to reciprocate the bracket 320 is configured, for example, a rodless air cylinder or a linear motor. And a holder 330 is mounted on the bracket 320 to hold the heat dissipation sheet 10.

The configuration of the holder 330 is a frame 331 formed in a square frame so that the block 430 is inserted through the left and right sides as shown in FIGS. 9 to 11. The frame 331 is configured such that the pierced portions on both sides correspond to the blocks 430 on both sides while moving between the frames 200 on both sides.

In addition, the arm 333 is configured to rotate on the upper 332 side of the frame 331 to press the upper 332. As an example, the hinge 335 is interposed between the arm 333 and the upper 332, so that the arm 333 is free to rotate. And a detachable means is mounted on the frame 331 to allow the arm 333 to be detachably attached to the upper part 332.

The desorption means is possible because, as an example, a magnet 337 mounted to correspond to the arm 333 is configured inside the upper 332. As an example, after drilling a hole, the magnet 337 may be inserted. At this time, of course, the arm 333 must be a magnetic body attached to the magnet 337. In addition, since the pin P protrudes from the upper portion 332 on the side of the magnet 337 and the through hole S corresponding to the pin P is formed on the arm 333, the arm 333 is a magnet. Attached to (337) so that the pin (P) is inserted into the through-hole (S) in a closed state so that the arm 333 is configured to be accurately combined with the upper 332.

In addition, the groove (V) is formed on the surface facing the arm (333) in the upper 332, the neck (13) of the heat dissipation sheet (10) is formed to be inserted in a state facing upward, heat is configured Since both sides 12 of the neck 13 in the sheet 10 conform to the groove V, the upper and lower sides are opened, and the upper part is narrow and the lower part is gradually wider. Therefore, the mounting height is set naturally in the state in which the heat dissipation sheet 10 is inserted into the groove V. At this time, both sides of the shortening 520 of the welding unit 500 correspond to both sides of the neck 13 facing upward. In addition, the blades 530 formed on one side of the single axis 520 in the state where the short sides 520 on both sides press the neck 13 are connected to the welds 15 formed on both sides of the neck 13 to the neck 13 It is configured to seal the formed inlet.

In addition, since the depth of the groove V is formed smaller than the thickness of the heat dissipation sheet 10, it is configured to press the heat dissipation sheet 10 while the arm 333 is attached to the magnet 337. . Therefore, the heat dissipation sheet 10 is configured to prevent the phenomenon of being separated downward.

In addition, as shown in FIG. 12, an elastic pad (A) formed to compress the heat dissipation sheet (10) is attached to the surface facing the groove (V) in the arm (333) may be further configured. The elastic pad (A) may be made of an elastic material such as rubber or urethane as an example. Therefore, since the heat dissipation sheet 10 is excessively compressed during compression, it is configured to prevent a phenomenon in which a passage through which air is exhausted is blocked during the heating step. That is, the elastic pad (A) serves to buffer against the pressure generated when the arm 333 is closed.

As another embodiment of the elastic pad (A) may be composed of a pad-shaped tube filled with air therein. The tube is provided with a valve free of air injection and exhaust, so that the degree of compression of the heat dissipation sheet 10 can be optimally matched through air injection and exhaust. Therefore, it is configured to hold the elastic pad (A) so that it does not escape downward while compressing so that the inside is not blocked.

Hereinafter, with reference to the accompanying drawings, an operation process of the apparatus for manufacturing the heat dissipation sheet will be described with reference to the method for manufacturing the heat dissipation sheet.

13 is in the manufacturing apparatus of the heat dissipation sheet according to the present invention (a) is a front view and (b) is a right side view, a working state diagram showing a state in which the heat dissipation sheet is held, Figure 14 is a heat dissipation sheet is held in Figure 13 It is a working state diagram showing that the holder is transferred between the heating unit and the welding unit, Figure 15 is a working state diagram showing a state in which the heat dissipation sheet is heated by the heating unit in Figure 14, Figure 16 is a welding unit in Figure 15 It is a working state diagram showing a state in which the neck of the heat dissipation sheet is supported, and FIG. 17 is a work state diagram showing a state in which the inlet formed in the net of the heat dissipation sheet is closed by the welding unit in FIG. 16.

13, after the loading unit 300 is moved to the front of the frame 200, the arm 333 of the holder 330 is opened as in FIG. 10, and then the upper portion 332 of the frame 331 ) After the heat dissipation sheet 10 is closely adhered to the side, the arm 333 is closed to be attached to the magnet 337 which is a detachable means. At this time, since the heat dissipation sheet 10 is inserted into the groove V, the mounting height is naturally set. In addition, since the pin P is inserted into the through-hole S formed in the arm 333, the arm 333 can be accurately combined with the upper 332 without being displaced.

In this state, as shown in FIG. 14, the actuator 310 of the loading unit 300 is driven to move the holder 330 between the frames 200 on both sides. At this time, the heating unit 400 and the welding unit 500 on both sides correspond to the held heat dissipation sheet 10. That is, the block 430 of the heating unit 400 corresponds to the heat dissipation sheet 10 through the opening of the frame 331, and the shortening 520 of the welding unit 500 is the heat dissipation sheet 10. Corresponds to the neck (13).

In this state, as shown in FIG. 15, the heating step suggested in the method of manufacturing the heat dissipation sheet already described is performed. That is, the blocks 430 on both sides are in close contact with both sides of the heat dissipation sheet 10 by driving the actuator 413 of the heating unit 400. At this time, of course, the compression force is adjusted so that the space inside the heat dissipation sheet 10 is not blocked. In this state, as suggested in the heating step, the working fluid charged therein is heated to vaporize. Then, as the vaporized working fluid is exhausted through the inlet of the neck 13, the air is first pushed out, so the inside of the heat dissipation sheet is in a vacuum.

Next, a welding step suggested in the method of manufacturing the heat dissipation sheet already described is performed. As shown in FIG. 16, one side of the shortening 520 of the one side actuator 520 of the welding unit 500, that is, the blade ( A short axis 520 in which 530 is not formed is in close contact with one side of the neck 13. Next, by the operation of the counterpart actuator 500, the counterpart short axis 520, that is, the short axis 520 on which the blade 530 is formed advances to compress the neck 13. At this time, since electric current is conducted to the short axis 520 on both sides, electric resistance heat is generated in the neck 13, so that resistance welding is performed and the opening of the neck 13 is realized as the suggested process is realized in the welding step. It is closed. In this case, the blade 530 is linearly pressurized in a state connected to the welds 15 formed on both sides of the neck 13, so as shown in FIG. 5, the front end G of the neck 13 is welded on both sides 15 ) Is connected to another linear welding part (E), so that the entrance of the neck (13) is easily closed. At this time, the block 430 of the heating unit 400 may be separated from the heat dissipation sheet 10 or may maintain a close contact state.

When the finishing work is completed in this way, the block 430 and the short axis 520 are separated from the heat dissipation sheet 10, and the actuator 310 of the loading unit 300 is operated to retract the holder 330 to frame it. It should be located in front of (200). In addition, since the arm 333 of the holder 330 is opened to release the heat dissipation sheet 10, the operation is completed.

As described above, according to the manufacturing method and manufacturing apparatus 90 of the heat dissipation sheet according to the present invention, the working fluid inside the heat dissipation sheet 10 is vaporized and exhausted to the inlet formed in the neck 13, so that the introduced air is also at the same time. Can be discharged. The air is exhausted at the same time, and the opening of the neck 13 is closed by welding by electric resistance heat, that is, electric resistance welding, so that the heat dissipation sheet 10 filled only with the working fluid in a vacuum can be easily manufactured. Therefore, since heat dissipation due to smooth heat transfer is possible, there is an advantage of efficiently cooling the portable terminal. In general, since the highest thermal insulation coefficient is air, it is a matter that anyone skilled in the art knows that it is possible to obtain the smoothest electrical conductivity in a vacuum, so a detailed description thereof will be omitted. Particularly, according to the apparatus for manufacturing a heat dissipation sheet according to the present invention, since the heat dissipation sheet capable of the above-mentioned effects can be easily and quickly manufactured, there is an effect of improving productivity.
