A method of manufacturing a back cover for a portable terminal according to the present invention comprises the steps of: attaching a leather sheet (G) having a spare edge (G1) and a cover plate (C) having a cover edge (C1) A spare edge G1 of the leather sheet G adhered to the back surface of the cover plate C is pressed toward the center of the cover plate C as shown in Fig. (S10) of sticking the cover frame (C1) by pushing in the horizontal direction, and a step (S20) of pressing the spare frame (G1) adhered to the cover frame (C1).
The spare frame G1 of the leather sheet G is pushed horizontally toward the center of the cover plate C to adhere to the cover frame C1 according to the manufacturing method of the back cover for a portable terminal according to the present invention, The spacer rim G1 bonded to the spacer rim C1 can be compressed again to ensure a simple and firm adhesion between the spare rim G1 and the cover rim C1.
The step S10 is a step S11 of pushing the corner of the spare frame G1 toward the corner of the cover frame C1 and sticking the side portion of the spare frame G1 to the side of the cover frame C1 (Step S12).
When the spacer frame G1 is adhered to the cover frame C1, the corner portion of the spacer frame G1 is firstly pushed and adhered, and then the spacer frame G1 side portion is pushed and adhered to the corner portion of the spacer frame G1. A phenomenon in which the spare frame G1 is folded and overlapped, which is caused when the side portion is pushed all at once, is prevented in advance to prevent defects.
At this time, the S10 and S20 steps are performed in such a manner that the spare edge G1 is thermally adhered to the cover edge C1 (for example, in order to prevent the burning phenomenon of the leather sheet G, 10 ° C), and the spare frame G1 is more firmly thermally adhered to the cover frame C1, thereby completing the back cover B.
