2 and 3 are a perspective view and a cross-sectional view illustrating a pressurizing jig for bonding a disparate material laminate according to an embodiment of the present invention, and FIG. 4 is a cross- Fig. 2 and 3, a pressurizing jig 30 according to an embodiment of the present invention includes a device for manufacturing the mobile phone case 10 shown in FIG. 1 by adhering the cradle 15 to the outer skin 11, And includes a lower mold 45, an upper mold 31 disposed above the lower mold 45, and a heater 35.

The lower mold 45 includes a lower mold base 46 and a cradle support layer 48 stacked on the lower mold base 46 and a cradle tightening portion 49 protruding from the upper side of the cradle support layer 48 .

The cradle support layer 48 and the cradle attachment portion 49 are preferably made of the same material.

The lower mold base 46 is supported on a flat surface or table and is made of a rigid metal material capable of withstanding pressure when it is in close contact with the upper mold 31. For example, the upper mold 31 may be formed of aluminum (Al) or an aluminum alloy which is light and has excellent heat conduction characteristics.

The cradle support layer 48 is formed of an elastic material. The elastic material may be, for example, a rubber elastic material such as a urethane elastomer. The cradle support layer 48 of the elastic material is cushioned so that the upper surface of the lower mold 45 contacting the cradle 15 or the cradle 15 is not damaged when the upper mold 31 and the lower mold 45 are closely contacted. And it is possible to adhere to the curved surface of the cradle. When the pressure is released, it can be restored to its original shape.

 The cradle contact portion 49 is formed on the upper surface of the lower mold 45 so that the inner surface of the cradle 15 and specifically the concave inner surface of the mobile phone support portion 16 are brought into close contact with the inner surface of the mobile phone support portion 16 And is gently protruded so as to correspond to the side surface. The central portion of the lower mold base 46 of the metal material protrudes more than the peripheral portion so that the deformation of the cradle tight fitting portion 49 made of an elastic material can be suppressed when the upper mold 31 and the lower mold 45 are in close contact with each other .

The upper mold 31 includes an upper mold base 32, a sheath pressing layer 36 laminated below the upper mold base 32, a sheath tightening portion 38 formed on the lower side of the sheath pressing layer 36, , And a fixed frame (40). The upper mold base 32 can be lowered to approach the lower mold 45 or conversely can be moved away from the lower mold 45. The lifting and lowering of the upper mold base 32 may be driven by, for example, a motor or a hydraulic cylinder, or may be driven by an operator's human power. The upper mold base 32 may also be formed of a metal material such as aluminum (Al) or an aluminum alloy in the same manner as the lower mold base 46.

The outer skin layer 36 is formed of an elastic material, such as a urethane elastomer, similar to the cradle support layer 48. The outer skin pressing layer 36 of the elastic material is used as a buffer layer so as not to damage the upper surface of the upper mold 31 contacting the outer skin 11 or the outer skin 11 when the upper mold 31 and the lower mold 45 are in close contact. Function, and when the pressure is released, it can be restored to its original shape.

The outer skin pressing layer 36 is a lower surface of the upper mold 31 and is gently punched out corresponding to the outer surface of the cradle 15, specifically, the shape of the outer surface, which is a three-dimensional curved surface of the mobile phone support 16 . However, unlike the embodiment shown in FIGS. 2 and 3, when the outer surface of the cradle is concave or flat, the outer skin pressure layer may be formed in a convex or flat shape corresponding to the shape of the outer surface of the cradle.

The outer skin pressing layer 36 and the outer skin tightening portion 38 may be integrally formed of the same material. That is, the outer skin tightening portion is formed by: The lower surface of the shell pressing layer 36 is formed in the same shape as the outer surface of the cradle through a forming operation or the like.

The fixed frame 40 is a rectangular window frame shaped member having an empty hole at the center. The pressurizing layer 36 of the upper mold 31 is pressed against the central through hole of the fixture 40 so that the fixture 40 is engaged with the pressurization layer 36.

The fixing frame 40 surrounds the outer surface of the outer skin pressing layer 36 so that the shape of the outer skin tightening portion 38 is maintained. The fixed frame 40 is made of a rigid metal material capable of withstanding pressure that the envelope pressing layer 36 is pushed outward when the upper mold 31 and the lower mold 45 are brought into close contact with each other. For example, the fixed frame 40 may be formed of aluminum (Al) or an aluminum alloy which is light and has excellent heat conduction characteristics.

Accordingly, even when the jig is pressurized, the elastic contact material 38 is prevented from being pushed outwardly, so that the cradle and the sheath can be pressed in an exact form together with the cradle close- do.

In this case, the upper and lower widths of the pressing layer, which is a resilient material, can be reduced when the outer covering and the cradle are adhered to each other. Accordingly, as shown in FIG. 4, Can be fitted to the side of the cradle support layer 48 together with the side surface of the cradle 36 so that the outer shell can be accurately bonded to the cradle outer surface without wrinkles.

A chamfer 41 may be formed on the outer lower edge of the fixed frame 40. The chamfered surface 41 may be in the shape of an inclined surface bent obliquely at the boundary with the peripheral side surface as shown in Figs. 2 and 3, or may be curved. If the chamfered surface 41 is not provided, the upper mold 31 is lowered and brought into close contact with the lower mold 45, so that the fixed mold 40 may collide with the lower mold 45, May occur and the sheath 11 or the cradle 15 may be damaged, so that the chamfer surface 41 prevents such accident and damage.

The heater 35 heats the adhesive 25 interposed between the cradle 15 and the outer shell 11 when the cradle 15 and the outer shell 11 are brought into close contact with each other between the upper mold 31 and the lower mold 45 For example, a hot wire that generates heat by power supply. The heater 35 is provided inside the upper mold base 32. 4, the heat is transferred to the adhesive 25 through the upper mold base 32, the outer skin pressure layer 36, and the outer skin 11. The positions of the heaters are not limited to the inside of the upper mold base 32 but may be provided inside the lower mold base 46 or inside the upper mold base 32 and the lower mold base 46, have.

3 and 5 together, step S10 specifically shows that the inner surface of the cradle 15, in other words the concave inner surface of the mobile phone support 16, is attached to the cradle attachment 49 of the lower mold 45 And placing the cradle 15 on the lower mold 45 so as to face each other. Step S20 is a step of applying an adhesive 25 to the outer surface of the cradle 15, and the adhesive 25 may be, for example, hot melt. The hot melt may be provided in the form of a film by using the properties of a thermoplastic resin which is repeatedly melted when heat is applied and hardened when it is cooled. A film-shaped hot melt can be placed on the outer surface of the cradle 15. Step S30 is a step of placing the outer shell 11 on the outer surface of the cradle 15 so that the cradle attachment portion 12 of the outer shell 11 is positioned above the outer surface of the cradle 15 in step S30.

4 and 5, in step S40, the outer covering 38 of the upper mold 31 presses the cradle attaching portion 12 (see Fig. 3) of the outer shell 11 to press the cradle attaching portion 12 Is lowered toward the lower mold 45 so that the upper mold 31 is brought into close contact with the outer surface of the cradle 15. In step S50, the heat generated in the heater 35 is transferred to the hot melt adhesive 25 through the upper mold 31 and the enclosure 11 closely attached thereto, whereby the hot melt adhesive 25 is melted, And the outer shell 11 is joined. The hot melt adhesive 25 in the form of a film is heated and melted since it is pressed by the upper mold 31 and the lower mold 45 to connect the cradle 15 and the outer shell 11 to each other. The hot melt adhesive 25 must be pressurized and heated at a suitable pressure and temperature for a sufficient time to melt. In addition, when the upper mold 31 and the lower mold 45 are separated from each other and the cradle 15 and the sheath 11 are separated from the pressing jig 30 (see FIG. 2) The melted hot melt adhesive 25 is hardened and the cradle 15 and the shell 11 are firmly coupled. On the other hand, if the adhesive 25 is a kind of adhesive other than hot melt, a specialized step may be carried out to improve the adhesive performance of the adhesive.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention.
