And the four-stage bonding machine is a high frequency bonding machine.
The sixth step is characterized in that the main body is turned upside down so that the opening is directed downward and is coupled to the seating groove of the bonding jig and is adhered to one side of the rear surface of the main body of the connection portion of the cover.
In the step 6, an adhesive is applied to the connection portion of the cover and is adhered to one side of the main body.
In the step 6, a rivet screw may be attached to the connection portion of the cover to enhance the binding force or to improve the decoration effect.
According to another aspect of the present invention, there is provided a portable terminal comprising: a main body accommodating a portable terminal; and a cover formed to cover a front surface of the main body, And a protective case for a portable device, which can be opened and closed.
The main body is a soft synthetic resin, and the cover is a leather material.
The cover is formed in a plate shape so as to cover a front surface of the main body, and a connecting portion is formed on one side of the main body so as to be attached to one side surface and a lower surface of the main body. .
The adhesive means is characterized by high frequency sealing or heat sealing.
And a polyurethane or polyethylene sheet melted by heat is formed on one surface of the connection portion of the cover.
According to the present invention, a cover is formed to cover a front surface of a main body, which is made of a soft synthetic resin material and accommodates the portable terminal, and the cover is bonded to one side of the main body by high frequency bonding, And price competitiveness can be improved.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
2 is a perspective view illustrating a protective case for a portable device according to the present invention, and Fig. 3 is a perspective view showing a portable case according to the present invention. Fig. FIG. 4 is a rear perspective view of a protective case for a portable device according to the present invention. FIG.
As shown in FIG. 1, a method of manufacturing a protective case for a portable device according to the present invention includes: a first step S1 of seating a lining material and a sheath material on a jig, the holes being punched for reference; (S2) of arranging the core material on the upper surface of the outer cloth; (S3) of arranging the lining material on the upper surface of the core material and assembling the lining material together with the outer surface of the core material; (S4) of putting the laminate of the third step (S3) into the bonding machine and allowing the laminate to adhere integrally by bonding; Step S5 (S5) of completing the
In the first step S1, the lining and the outer surface are put on the punching machine and punched to form a hole. The hole seats the fabric on the jig and serves as a reference point for arranging the jig for assembly.
In step 2 (S2), the core is placed at the correct position using the jig on the top surface with the outer surface unfolded, each corner fixed, and tightly tensioned.
The core is a hard plate.
The core material can be any material such as paper, polymer, epoxy, etc. Preferably, paper or polypropylene materials are used for cost, versatility and processing comfort.
A core is punched into a punching machine to form a hole. The hole is a hole corresponding to a button, a sound receiving port, and a camera lens provided in the portable terminal.
In step S3 (S3), the lining is assembled by arranging the lining on the top surface of the core material so that the outer surface, the core material, and the lining are all overlapped.
Further, a pocket may be further formed by further attaching a fabric having a pocket groove formed on the upper surface of the lining.
Pockets are used to store cards and business cards.
Step 4 (S4) inserts the resultant of the step (S3) into a bonding machine. The bonding machine is preferably a high frequency bonding machine.
High-frequency bonding is a type of thermal bonding of a film, in which a polymer having a dielectric loss of 10-2 or higher is subjected to dielectric loss due to polar molecules in the film using a high frequency electric field of about 50 to 80 MHz, So that the high-frequency bonding is a well-known technical idea, so that a detailed description thereof will be omitted.
Alternatively, the above-mentioned adhesive may be a hot melt adhesive.
In step S5 (S5), the plate-shaped cover is completed by inserting the bonded piece into the cutter and cutting it.
Here, the punching obtained in the third step (S3) is punched to form a through hole corresponding to the hole of the core material in the above-described step (S2).
In step S6, the main body 1 is seated on the adhesive jig, and the adhesive jig is formed with a receiving groove so that the main body 1 can be inverted and stored.
That is, the main body 1 is made of a soft material and has an upper portion opened and formed of a side wall and a lower plate. When turned upside down, the side wall can be inserted and fixed in the seating groove of the bonding jig.
