Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a method of manufacturing a smartphone cover, and more particularly, to a method of manufacturing a smartphone cover for manufacturing a smartphone cover by side-
According to a protective case for a portable device and a method for manufacturing the same, a protective case for a portable device includes a first step of placing the outer case on a jig, a button of a mobile device, A step of arranging a core material having holes corresponding to the lens on an upper surface of the outer surface, a step of arranging a lining material on the upper surface of the core material and assembling the outer core material so as to form a joint with the outer material, The method comprising the steps of: (1) a step of integrally adhering the joints; (3) a step of placing the bonded joints of the four steps in a cutter and cutting the joints into a predetermined shape to complete the cover; And bonding the connection part of the cover obtained in the step 5 to one side of the main body, the main body being made of soft synthetic resin and being accommodated in the portable terminal, And a cover which is attached to one side of the main body and bonded to one side of the main body by an adhesive means so that the cover can be opened and closed. The cover is formed so as to cover the front surface, and the cover is adhered to one side of the body by high-frequency bonding, thereby reducing the number of manufacturing steps and materials, and improving the productivity and cost competitiveness.
However, since the leather of the conventional smartphone cover is provided only in the visible portion of the backside, when the smartphone cover is held in the hand, the side of the smartphone cover, which is the main part determining the feeling of being wrapped around the hand, Has been found to be a major factor in dropping the smartphone or reducing the sense of grip held in one hand because it is a metal or a synthetic resin.
Particularly, this problem is a problem that must be solved because it has a function of maintaining the durability of the product as well as the performance of the product and increasing the service period so as not to replace the expensive smart phone.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a method of manufacturing a smartphone cover for manufacturing leather such that the leather is wrapped around the periphery of the smartphone so as to increase the gripping sensitivity of the product .
According to an aspect of the present invention, there is provided a method of manufacturing a smartphone cover including a leather having an area larger than a back surface area of the smartphone cover, and attaching leather to the back and periphery of the smartphone cover.
In this manufacturing method, a contact pressing step (S112) aligning and pressing the case and the leather constituting the smartphone cover; A first thermal compression step (S113) of thermocompressing a visible portion of the case using hot melt; A side cutting step (S114) of cutting the leather padded on the back surface of the case to a size that is wound inward at the rim portion; And a peripheral squeezing step (S115) for adhering the leather so as to blur on the back side of the case.
In an embodiment, the peripheral squeezing step (S115) comprises: A first cylinder loading step (S1161) of placing a first cylinder using hydraulic pressure on the case and the upper portion of the leather; A first upper pressing step (S1162) of pressing on the case and the upper portion of the leather to fix the case and the leather using the first cylinder; A corner pressing step (S1163) of thermally pressing four corner portions of the case and the leather; A side pressing step (S1164) of thermally compressing the four side portions of the case and the leather; A second cylinder loading step (S1165) of placing a second cylinder using hydraulic pressure on the case and the upper portion of the leather; And a second upper pressing step (S1166) for thermally pressing the leather portion folded to the side of the case at the upper portion of the case and the leather.
In the embodiment, a mirror printing step (S111) in which mirror printing is performed so as to increase the wireless communication sensitivity by adding a silver component to a portion where the antenna is installed in the case, ).
In an embodiment, after the peripheral squeezing step (S115); (S116) a second heat pressing step of thermally pressing the leather-wrapped area of the case using hot melt; A center sticking step (S117) in which a center portion of the leather is stamped with heat and pressure with a fake stitch feeling; A backside spray coating step (S118) of coating a cut section of the leather with a urethane spray to prevent moisture from entering the cut surface of the leather; (S119) of coating a cross section of the hole with water-soluble urethane so as to prevent moisture from flowing into the cross section of the hole of the leather.
In an embodiment, a hot melt adhesive which is in the form of a sheet and is thermally bonded is used between the case and the leather.
According to the preferred effect of the present invention, since the leather is wrapped around the periphery of the smartphone to increase the gripping sensitivity of the product, the grip sensitivity is remarkably increased so as not to drop the smartphone, It provides the advantage of not letting the hand holding the smartphone cool in the weather, and it has the effect of upgrading the level of the product with the performance of the product.
