The best mode for achieving the object of the present invention is a method for manufacturing a metal deco frame used in portable electronic devices is a raw material preparation step (S10) and a metal prepared in the step (S10) to prepare a metal bar type material Cross-section processing step (S20) of bending and cutting the cross section of the bar-type material Frame bending step (S60) of bending the metal bar-type material processed in the step (S20) in the shape of a frame according to the use of the electronic device used; In the step (S60) is composed of a joint portion joining step (S70) for joining both ends of the frame of the metal bar-type material processed in the step (S60).

Hereinafter, a method for manufacturing a metal deco frame used in a portable electronic device of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily perform the method.

1 is a flow chart illustrating the process of the present invention.

Referring to Figure 1 in detail, the manufacturing method of the metal deco frame used in the portable electronic device of the present invention is a raw material preparation step (S10), cross-section processing step (S20), frame bending step (S60) and joints Step (S70), may optionally further include any one or more of the shape punching step (S30), NC processing step (S40), nut coupling step (S50) before the frame bending step (S60).

The raw material preparation step (S10) is a process for preparing a material (see Fig. 2) from the raw material to the metal bar type to prepare a metal bar type material by punching out a conventional metal plate, or a suitable length of the raw material of the metal plate shape It is prepared by cutting with or by cutting a metal bar to an appropriate length.

Here, the method of punching the metal plate is to punch the metal plate of the same height as the width of the finished metal deco frame by laser cutting or the like to prepare a metal bar type material.

In addition, a method of preparing a metal plate-shaped raw material by cutting it to an appropriate length is to prepare a metal bar-type material by using a method such as machine cutting or laser cutting on a metal plate having the same thickness as that of the finished metal deco frame. will be.

In addition, the method of preparing by cutting the metal bar to an appropriate length is to prepare a metal bar type material by cutting the metal bar having the same thickness and width as the finished metal teco frame to an appropriate length.

One of these methods is to prepare raw materials.

The metal bar type material prepared in the raw material preparation step (S10) as described above is subjected to the cross-sectional processing step (S20). (See FIG. 3).

In this case, one or more metal bars may be prepared and subjected to a cross-sectional processing process (S20), where one metal bar or a plurality of metal bars may be combined to complete a metal deco frame. 10)

This can be selectively applied according to the electronic device in which the finished metal deco frame is used. For example, a small electronic device such as a mobile phone adopts a method using one metal bar, and a medium to large size such as a palmtop or a notebook. The electronic device is to apply a method using a plurality of metal bars.

The cross-sectional processing step (S20) is completed by bending after cutting a portion of the cross section of the metal bar type material.

In more detail, after bending a portion of the side of the metal bar in an "L" shape, the bent edge portion is cut to perform a chamfering process, and both edges of the bent end are cut.

The reason why the side portion is bent into an "L" shape is to reinforce the strength in order to prevent distortion, etc. in the manufacture of the frame, so that the various components combined when producing portable electronic devices can be better seated. It is for.

Here, various shapes may be applied when cutting corners and ends as described above, and the matters described in the drawings and the detailed description of the present invention are not limited thereto.

After completion of the cross-sectional processing step (S20) as described above, the frame bending step (S60) and the joint portion joining step (S70) is made to complete the metal deco frame, but optionally another process is further added.

Here, the description will be given as an example of adding another process.

Therefore, the cross-section processing step (S20) after the shape punching step (S30), NC processing step (S40) and the nut coupling step (S50) in order to proceed to explain as an example.

In the cross-sectional processing step (S20), the shape punching process (S30) for punching a portion of the metal bar type of the cross-section processed to form a place where various subsidiary materials provided in the portable electronic device is located. Reference)

For example, when applied to the side frame of the mobile phone is to allow the subsidiary materials to be located by drilling a part of the location where the charging jack, volume key, earphone jack, ON / OFF power button is located.

The metal bar type material, which is partially punched out in the shape punching process (S30), is subjected to an etching operation through the NC machining process (S40).

In more detail, the surface treatment of the perforated part in the previous step (S30) and the operation for forming a coupling portion for coupling the nut to be worked in the later step.

For example, in the case of a mobile phone, when a circuit board or upper and lower covers, etc., which are provided inside, are coupled, or when a subsidiary material is coupled, a corresponding nut is located when bolting is required.

To this end, after grooving a part of the surface is to combine the nut in a coupling method such as welding in the post-process (S40).

In the NC processing process (S40), after performing the grooving operation on a portion of the metal bar type material, the nut coupling process (S50) for joining the members such as the coupling nut is subjected to (see FIG. 6).

At this time, the nut coupling step (S50) is to place the coupling nut in the grooved portion of the metal bar and then coupled by welding or the like.

The metal bar type material that passed through the nut coupling process (S50) is subjected to a frame bending process (S60) of bending in a frame shape suitable for the use of the electronic device used.

At this time, the "L" shaped protrusion formed on one side of the metal bar is bent to face inward.

As described above, bending of the protrusion to face inward is not limited thereto.

After the frame bending process (S60), the coupling portion (S70) to complete the frame by combining the both ends of the frame is performed (see Figs. 7 to 10).

The joint joining process (S70) as described above uses a conventional method such as electric welding, mechanical welding, gas welding.

At this time, both ends of the frame before coupling in the joint portion joining process (S70) is formed in a variety of shapes after the welding operation is made.

For example, the both ends are maintained to maintain a flat surface, or the two ends are processed into various shapes such as irregularities and grooves, a plurality of teeth, a plurality of protrusions, wedges, etc. .

After the temporary coupling to both ends of the spaced apart by the above process for easy welding, the welding operation is carried out, or to form a variety of shapes to increase the bonding force to perform the work.

The frame after the work is completed through the above process may further include a post-processing work process (S80).

Various methods are also used for surface treatment by the post treatment operation.

For example, there may be a process such as grinding flatness after welding to the joint, anodizing for minimizing the visual identification of the joint, hairline post-processing, and buffing post-processing.

Hereinafter, various embodiments according to the present invention will be described further.
