Description

{Jig for case of hand phone}

The present invention relates to a jig device for processing a mobile phone case, and more particularly, to a jig device for processing a mobile phone case, which can firmly hold and fix a workpiece, can process a large amount of material in a narrow space, To a jig device for processing a cellular phone case in which the discharge of cutting oil is facilitated.

Further, the present invention relates to a jig device for processing a mobile phone case, which can simultaneously process a plurality of materials, thereby reducing the time required for replacing the tool and reducing the time required to re-insert the material, thereby improving productivity.

As electric and electronic technology has developed, various and convenient mobile phones have been developed and provided, and these mobile phones are becoming smaller in volume and lighter in weight in order to make them portable.

In order to achieve such a thin shape and light weight, it is necessary to make the structure thinner and downsize as well as downsize the electric and electronic parts. Recently, a cell phone case using lightweight and high strength reinforced aluminum has been used, and various techniques for manufacturing a cell phone case using such a reinforced aluminum have been developed.

There are a variety of techniques related to the technology for processing mobile phone cases, for example, Patent Documents 1 and 2.

Patent Document 1 discloses a sliding device which is provided on a main body of a lifting panel provided in a main body of a lifting panel and which is provided on a lifting means body for lifting up and down a lifting panel and sliding means for reciprocally sliding the lifting panel, A rotating means provided on the main body for receiving the rotational force of the motor and provided at both ends of the roll, and a rotating means for rotating the rotating means, And a sending means for sending a surface of the mobile phone case while turning the mobile phone case,

Patent Document 2 discloses a method of manufacturing a semiconductor device, which comprises a front surface cutting step in which a front surface margin is formed between cut lines at a boundary between a front surface of a case and a left and right surface of a case, A lower side cutting step on the back side of the case, the lower side being cut by a press to form the side left side surface and the lower side side margin portion; A right direction cutting step in which a left side face of the case is inclined and cut by a press, and a front face margin portion and a side margin portion located on the right side face of the case are cut; A left side cutting step in which a right side face of the case is inclined and cut by a press, the front side margin portion and the side margin portion being located on the left side of the case are cut; And a rear center cut-off step in which the center rear portion of the case is cut by a press.

Such a conventional cell phone case processing technique requires fixing the cell phone case to the jig to fix the surface of the thin plate while fixing the case of the thin plate, and such a fixing jig usually uses a vacuum jig as shown in Fig. 6 . That is, a plurality of vent holes 100h are formed in the jig body 100 having the case seating grooves 100p on which the cell phone case is seated, and air is sucked and discharged through the vent holes, And is fixed to the groove 100p.

However, such a conventional vacuum jig is disadvantageous in that when a clearance is formed between the case material and the case receiving groove 100p, the case material is separated from the case receiving groove 100p, causing the case material to bounce and fly during processing, .

Of course, it is possible to install a sealing ring 200 so as not to create a gap between the case seating groove 100p and the case material. However, since the sealing ring 200 is easily aged by frictional heat generated in the course of processing the case material, There was an inconvenience to be replaced.

Further, since the vacuum pressure is used and an air compressor or the like for vacuum is used, there is a disadvantage that not only the jig device is enlarged but also a lot of energy is consumed for driving.
