Definitions of these terms should be based on the content of this specification.

1 is a schematic view showing a jig device of the present invention.

1 may include a jig unit for supporting a plurality of terminal cases 10 stacked along a first direction for processing the shape of the terminal case or polishing the surface of the terminal case. can do.

The stacking of the terminal case 10 may be for processing a plurality of terminal cases 10 through a single step of a specific processing means.

For example, a case polishing apparatus may be provided to smoothly polish the surface of the terminal case 10 or to peel off mistaken paint on the terminal case 10.

The case polishing apparatus can polish the terminal case 10 by a method of rubbing the terminal case 10 with a sandpaper or a sandblasting method of spraying an abrasive.

In order to improve the working speed, a plurality of terminal cases 10 may be put into one step of the case polishing apparatus. However, if the plurality of terminal cases 10 are put in a laminated state without separate supporting means, the alignment state of each terminal tends to be disturbed by the pressure applied from the sandpaper or the jetting pressure of the abrasive.

When the alignment state is disturbed, the polishing state is different for each terminal case 10, so that a uniform processing result is hardly obtained. This problem can be solved by the jig unit.

The terminal case 10 may be provided with a surface extending in various directions. It is preferable that the first direction in which the terminal case 10 is stacked is the same as the extending direction of the machining surface so that the machining surface to be machined is exposed to the outside even when the plurality of terminal cases 10 are stacked.

For example, if the machining surface of the terminal case 10 is the outer side surface a, b, c, and d, then the z axis which is a common extending direction of the outer side surfaces a, b, c, and d may be the first direction.

For example, in an xyz space having mutually orthogonal x, y, and z axes, a first direction may be a z axis, a second direction may be an x axis, and a third direction may be a y axis.

1, the outer surface d may extend in a first direction and a third direction. And the other outer side surfaces extend in common in the first direction. Therefore, the terminal case 10 is preferably stacked in the first direction.

The terminal cases 10 need to be aligned with each other so that the plurality of terminal cases 10 laminated in the first direction are not disturbed.

The first and second jigs may be provided in the jig unit for aligning the respective terminal cases 10.

The first jig can align each terminal case 10 in the same position on the vertical direction in the first direction. For example, when the positions of the terminal cases 10 are different in the second direction and the third direction perpendicular to the first direction, the terminal cases 10 can not be aligned with each other. According to the first jig, the second direction position and the third direction position of each terminal case 10 may be identical to each other.

The second jig can limit the degree of freedom of rotation of each terminal case 10 about the rotation axis parallel to the first direction. When the first direction position and the third direction position are combined to define a plane position, the plane position of each terminal case 10 can be aligned by the first jig. However, if each terminal case 10 is rotated at the position aligned by the first jig, it is difficult to satisfy the alignment state required in the processing step. According to the second jig, the rotation of each terminal case 10, which has been aligned on the plane position, is restricted, so that a complete alignment state can be provided.

On the other hand, even when the terminal journals 10 are stacked with the first jig and the second jig being stacked in an aligned state, it is preferable to prevent the abrasive or particles used in the processing step from penetrating to the other surface . For this, the jig unit may include the third jig 310.

The surface other than the machined surface may be defined as the intermediate surface of the terminal case 10 spaced from the machined surface of the terminal case 10. [ At this time, the third jig 310 may cover the intermediate surface. Thus, the third jig 310 covering the intermediate surface can protect the intermediate surface from the processing means for processing the outer surface corresponding to the processed surface.

The first jig, the second jig, and the third jig 310 may be separately formed, or may be integrally formed.

First, the case where the jigs are separately formed will be described.

The jig unit shown in Fig. 1 may include a through-hole jig 320 extending in a first direction and passing through a plurality of terminal cases 10.

The through jig 320 corresponds to the first jig, and the plane positions of the respective terminals can be aligned in the same manner.

When the plurality of terminal cases 10 are stacked from the first position to the second position spaced from each other in the first direction, the through jig 320 includes a rod formed at a distance greater than the first position and the second position .

A stopper 321 for preventing the terminal case 10 from being detached from the through jig 320 may be attached to or detached from the end of the through jig 320. A through hole may be formed in the terminal case 10 so as to pass through the through jig 320. The diameter of the stopper 321 may be larger than the diameter of the through hole.

The detachable stopper 321 may be installed at both ends or one end of the through jig 320.

A third jig 310 may be installed in the terminal case 10 stacked along the first direction. At this time, the third jig 310 may be installed for each terminal case 10. If the specific terminal case 10 is in close contact with the other terminal case 10 so as to seal the intermediate surface of the other terminal case 10, only the terminal case 10 disposed at the first or second position is contacted with the third jig 310) may be applied.

The terminal case 10 may be inserted into the through-hole jig 320 or may be inserted into the through-hole jig 320 in a state where the third jig 310 is installed. In the latter case, a third jig 310 inserted into the through-hole jig 320 next to the terminal case 10 may be installed in the terminal case 10.

When the third jig 310 is applied, it is preferable that the terminal case 10 is fitted in the through jig 320 in a direction in which the intermediate surface covering the third jig 310 faces the stopper 321 . Even if the stopper 321 is mounted in a state where the third jig 310 is not installed in the specific terminal case 10, the stopper 321 can be pulled out, (10).

For example, it is assumed that the third jig 310 is applied only to the terminal case 10 disposed at one of the first position and the second position. It is assumed that the stopper 321 is attached to and detached from the first position side end of the through jig 320 and the stopper 321 is not removable at the second position side end of the through jig 320. [

If the terminal case 10 is inserted into the through-hole jig 320 in the direction in which the intermediate surface covering the third jig 310 faces the stopper 321, only the terminal case 10 of the first position 3 jig 310 may be applied. In this case, even if the stopper 321 is installed without the third jig 310, when the stopper 321 is released, the terminal case 10 on which the third jig 310 is to be installed is positioned easily The third jig 310 can be installed.

If the terminal case 10 is inserted into the through-hole jig 320 in the direction opposite to the stopper 321, the terminal case 10 of the second position is inserted into the through- Only the third jig 310 can be applied. In this case, if it is determined that the third jig 310 is not installed after inserting the terminal case 10 into the through-hole jig 320, all the terminal cases 10 inserted into the stopper 321 and the through- It is difficult to install the third jig 310 after removing the jig 310 from the through jig 320.

The third jig 310 covers an intermediate surface of the terminal case 10, and the shape of the third jig 310 can be determined according to the terminal case 10.

2 is a schematic view showing the terminal case 10; 2 is a planar perspective view of the terminal case 10.

As shown in FIG. 2, the terminal case 10 may include a metal region 20 including a metal and a resin region 30 including a synthetic resin.

The case of a mobile terminal such as a mobile phone and a notebook may require grip feeling, corrosion resistance, and aesthetic appearance considering durability and ease of use that can withstand various impacts. In order to satisfy such a requirement, the terminal case 10 can be painted with paint.

In the case where the painted surface on which the paint is painted in the terminal case 10 includes one material, the painting process may be completed by applying a putty suitable for the material and painting the paint on the putty. In addition, the painted state of the terminal case 10 painted in this manner can easily satisfy the initial design value in the thickness of paint, flatness, and the like.

However, if the terminal case 10 includes a metal material, a problem may occur in the painting process.

Even if the terminal case 10 includes a metal material, there may be no problem if the terminal case 10 is made of only one metal material as described above. However, there may be a case where it is difficult to constitute the terminal case 10 only of metal.

In the case of a mobile communication terminal such as a smart phone, it is preferable that the case is configured to pass radio waves for wireless communication. However, if the case is made of metal, the wireless communication function of the terminal can be paralyzed similarly to the principle that wireless communication is impossible in the elevator. In order to solve such a communication trouble, the terminal case 10 may be provided with so-called radio wave holes through which radio waves pass.

If the radio wave hole is left as it is, external foreign matter can flow into the inside of the terminal, so that the radio wave hole can be covered with a synthetic resin material that does not interfere with radio waves. According to this, a metal region 20 including a metal and a resin region 30 including a synthetic resin may be provided on one side of the terminal case 10. A camera hole 31 in which a camera module provided in the terminal is installed, an illumination hole 33 in which a lighting lamp is installed, a speaker hole 35 in which a speaker is installed, and the like may be provided in the resin region 30 or the metal region 20 have.

The camera holes 31, the illumination holes 33, the speaker holes 35, and the like may be through holes through which the through jigs 320 penetrate. According to this, it is not necessary to add a separate hole for the through jig 320 to pass through, so that the terminal case 10 can be prevented from being damaged.

The following problems may occur when a surface on which the metal region 20 and the resin region 30 are present is painted.

First, the terminal case 10 including the metal and the synthetic resin may be formed through insert injection. However, in this process, flatness is easily damaged due to difference in thermal expansion.

Particularly, since burrs are formed at the boundary between the metal region 20 and the resin region 30, the damage to the flatness can be more serious. Therefore, the surface where the metal region 20 and the resin region 30 coexist in the terminal case 10 needs to be polished by the machining means.

On the other hand, the outer surface of the terminal case 10 may also be smoothly polished or peeled off of the paint may be required. When the outer surface of the terminal case 10 is to be processed, the terminal case 10 may include only one material such as metal or resin.

A plurality of outer surfaces of the terminal case 10 may be provided. For example, in the case of a rectangular terminal case 10, there are four outer sides as shown in FIG.

3 is another schematic view showing the terminal case 10. 3, a bottom perspective view of the terminal case 10 is disclosed.

When the surface of the terminal case 10 excluding the outer surface extending in the first direction is referred to as an intermediate surface, the terminal case 10 may be provided with a receiving space 50 formed by an intermediate surface and an outer surface.

Hereinafter, for convenience of explanation, the surface facing the outside is referred to as an intermediate working surface as shown in Fig. 2 on the intermediate surface, and the surface facing the receiving space as shown in Fig. 3 on the intermediate surface, Quot;

In the accommodation space 50, various circuit components constituting the terminal, a battery, and the like can be accommodated. An insulating layer 40 may be formed on the protective surface to prevent electrical interference problems and short circuit problems between these circuit components or batteries. The protective surface may be provided with a screw hole to be screwed into a module provided with a circuit component or the like. These insulating layers (40) or screw holes need to be protected during processing of the intermediate working surface or the outer surface.

The third jig 310 covers the intermediate surface of the terminal case 10, specifically, the protective surface, and can protect the insulating layer 40 or the screw hole. Of course, the third jig 310 covering the protective surface of the specific terminal case 10 may also be configured to cover the intermediate processed surface of another terminal case 10 stacked on the specific terminal case 10.

4 is a schematic view showing a third jig 310 constituting the jig device of the present invention.

The third jig 310 may have a size that can be accommodated in the accommodation space 50 of the terminal case 10. The third jig 310 may be provided with an insertion protrusion 311 protruding in the first direction.

The insertion protrusion 311 may be inserted into a through hole such as a camera hole provided in the terminal case 10. So that the third jig 310 can be firmly fitted to the terminal case 10.

According to the insertion protrusion 311, the through-hole through which the through-jig 320 can pass through the terminal case 10 can be clogged. In order to prevent this, the insertion protrusion 311 may be provided with a jig hole 313 through which the through jig 320 passes.

If the third jig 310 is not provided, the through-hole jig 320 can directly contact the through-hole of the terminal case 10. Therefore, the through hole may be damaged by the external impact applied to the through jig 320. [ However, according to the insertion protrusion 311 and the jig hole 313, since the through-hole jig 320 contacts the jig hole 313 instead of contacting the through-hole, the through- The damage of the holes can be prevented.

According to the above-described through jig 320, the plane position of the terminal case 10 can be aligned, but the degree of freedom of rotation is difficult to be limited.

In order to limit the degree of freedom of rotation, the jig unit may include a receiving jig corresponding to the second jig.

The receiving jig may be provided with receiving grooves into which a plurality of terminal cases 10 supported by the through jig 320 are inserted.

The inner wall forming the receiving groove may be formed to contact the terminal case 10. At least two inner walls may be formed in the receiving groove so that the inner wall contacting the terminal case 10 limits the rotational degree of rotation of the terminal case 10. [ At this time, the terminal case 10 may be inserted between two inner walls. The two inner walls are parallel to each other and extend in a first direction and a direction perpendicular to the first direction.

In the first direction, an end of the receiving groove may be provided with an insertion groove into which the through jig 320 is inserted. Since the flow of the through jig 320 is restricted by the insertion groove, the terminal case 10 can be prevented from being shaken during processing.

Since the inlet of the receiving groove is open, one of the outer surfaces of the terminal case 10 accommodated in the receiving groove can be exposed to the outside through the inlet of the receiving groove. The outer surface exposed to the outside can be polished by a polishing apparatus or the like, and the outer surface and the intermediate surface other than the outer surface can be protected by the receiving jig.

The terminal case 10 may be provided with a plurality of outer surfaces which need to be exposed to the outside through the inlet of the receiving groove. However, the lengths of the outer side surfaces may be different from each other, and accordingly, it is necessary to provide a plurality of accommodating jigs having different accommodating grooves.

For example, if the terminal case 10 has a rectangular shape having four outer sides a, b, c, and d, the first receiving jig 330 for exposing the outer sides b and d having the same length, A second receiving jig 340 may be provided for exposing.

5 is a schematic view showing a first receiving jig 330 constituting the jig device of the present invention.

The first receiving jig 330 may be provided with a first receiving groove 331. The first receiving groove 331 may have a first insertion groove 333 through which the through-hole 320 is inserted.

The terminal case 10 may be inserted into the first receiving groove 331 such that the fourth outer surface d of the terminal case 10 is exposed. Alternatively, the terminal case 10 may be inserted into the first receiving groove 331 such that the second outer side b 'having the same length as the fourth outer side d is exposed.

For example, if the fourth outer surface d is exposed when the terminal case 10 is inserted into the first receiving jig 330 in the state of Fig. 1, it is rotated 180 degrees about the through jig 320 in the state of Fig. The second outer side surface b is exposed when the first receiving jig 330 is inserted into the first receiving jig 330.

The distance L1 from the entrance of the first receiving groove 331 to the end of the first insertion groove 333 is equal to or greater than the length from the through jig 320 to the fourth outside surface d, It may be more than the length up to side b. When the length from the through jig 320 to the fourth outer surface d and the length from the through jig 320 to the second outer surface b are L2, L1 may be L2 or more.

The reason why the length from the through jig 320 to the fourth outer surface d is different from the length from the through jig 320 to the second outer surface b is because the through hole of the terminal case 10 is biased to one side .

The through jig 320 may penetrate the through hole formed in the terminal case 10 to prevent the terminal case 10 from being damaged. 1, the position of the through jig 320 (x-axis position in the drawing) and the position of the through jig 320 when the terminal case 10 rotates 180 degrees as shown in Fig. 6 The positions can be different from each other. 6 is a schematic view showing a state in which the jig unit of FIG. 1 is rotated by 180 degrees. In order that the through jig 320 can be inserted into the first insertion groove 333 regardless of the attitude of the terminal case 10, L2 or more.

On the other hand, the terminal case 10 can not be inserted into the first receiving jig 330 in a posture rotated 90 degrees in the forward or reverse direction in the state of FIG. The 90 degree rotated position is for exposing the first outer side surface a or the third outer side surface c. The terminal case 10 at this time can be inserted into the second accommodating jig 340 provided separately.

7 is a schematic view showing a second receiving jig 340 constituting the jig device of the present invention.

The second receiving jig 340 may be provided with a second receiving groove 341. A second insertion groove 343 and a third insertion groove 345 in which the through jig 320 is inserted may be provided at one end of the second receiving groove 341.

The terminal case 10 may be inserted into the second receiving groove 341 such that the third outer side face c of the terminal case 10 is exposed. The terminal case 10 may be inserted into the second receiving groove 341 such that the first outer side surface a having the same length as the third outer side surface is exposed.

At this time, the through jig 320 when the terminal case 10 is inserted into the second receiving groove 341 may be inserted into the second insertion groove 343 so that the third outer side face c is exposed.

For example, the terminal case 10 having the posture as shown in FIG. 8 may be inserted into the second insertion groove 343.

8 is a schematic view showing a state in which the jig unit of Fig. 1 is rotated 90 degrees in a normal direction. At this time, the forward direction may be counterclockwise.

Referring to FIG. 8, the through-hole jig 320 supporting the terminal case 10 is biased to the left in the y-axis direction. The second insertion groove 343 may be provided at a position where the through jig 320 of FIG. 8 is disposed in the y-axis direction.

Fig. 9 is a schematic view showing a state in which the jig unit of Fig. 1 is rotated in the reverse direction by 90 degrees. Fig. At this time, the reverse direction may be clockwise.

The through jig 320 may be inserted into the third insertion groove 345 when the terminal case 10 is inserted into the second receiving groove 341 so that the first outer side surface a is exposed.

For example, the terminal case 10 having the posture as shown in FIG. 9 may be inserted into the third insertion groove 345.

9 shows a state in which the through jig 320 supporting the terminal case 10 is positioned on the right side on the y axis. The third insertion groove 345 may be provided on the y axis at a position where the through jig 320 of FIG. 9 is disposed.

According to the through jig 320 and the receiving jig, the terminal case 10 can be stacked in a plurality of aligned states. Only one outer surface of the terminal case 10 can be exposed to the outside. Therefore, the other surface excluding the outer surface exposed to the outside can be protected by the receiving jig. For example, the terminal case 10 housed in the receiving jig may be introduced into a polishing apparatus in which an abrasive is sprayed. The polishing apparatus can spray the abrasive at a high speed to polish the outer surface exposed to the outside. It is difficult for the abrasive sprayed in this way to strike other than the outer surface. However, according to the receiving jig, there is no problem because the other surface except the outer surface to be polished is protected.

However, a plurality of receiving jigs is required for machining a plurality of outer surfaces, and it is necessary to change the posture of the terminal case 10 manually.

The posture of the terminal case 10 can be automatically changed by the rotating means when the necessity to protect the portion except the machined surface is low.

For example, in the case of a polishing apparatus for polishing a work surface with a sandpaper, a surface not contacting the sandpaper is not damaged by the sandpaper even when exposed to the outside.

In this case, it is preferable that the terminal case 10 be rotated such that a plurality of outer surfaces provided in the terminal case 10 face the respective sandpaper. It is preferable that all the outer surfaces of the terminal case 10 are exposed to the outside.

According to this, a jig for aligning the plane positions of the plurality of terminal cases 10 and restricting the degree of freedom of rotation is required while all the outer surfaces are exposed to the outside.

10 is a schematic view showing another jig device of the present invention.

The jig unit may include an intermediate jig 350 that supports the intermediate surface. At this time, the intermediate jig 350 may include a through-boss 351 and a connection groove 352 in order to combine the functions of the first jig and the second jig described above.

Specifically, a plurality of through protrusions 351 protruding in the first direction and passing through the terminal case 10 may be provided on the first surface of the intermediate jig 350.

If the through protrusions 351 are provided in a single number, it is difficult to limit the degree of freedom of rotation of the terminal case 10 as in the through jig 320 described above. However, if a plurality of through protrusions 351 penetrating the terminal case 10 are provided at different positions on the first surface of the intermediate jig 350, the rotational degree of rotation of the terminal case 10 may be restricted.

Therefore, the intermediate jig 350 can perform both the functions of the first jig and the second jig by only being installed on the intermediate working surface or the protective surface of the terminal case 10.

Fig. 11 is a plan perspective view showing an intermediate jig 350 constituting the jig device of the present invention, and Fig. 12 is a bottom perspective view showing an intermediate jig 350 constituting the jig device of the present invention.

In other words, a plurality of through protrusions 351 are provided on the first surface. At this time, the through protrusions 351 may correspond to the plurality of through holes formed in the terminal case 10, respectively.

The projecting length of the penetrating protrusion 351 may be longer than the thickness of the terminal case 10 in order to align the plane position of the terminal case 10. [ According to this, the through protrusion 351 passing through the terminal case 10 can protrude from the terminal case 10.

The end of the penetrating projection 351 protruding from the terminal case 10 in this way can be fitted in the other intermediate jig 350. The through protrusions 351 provided in the other intermediate jigs 350 are fitted in another intermediate jig 350 and the terminal case 10 interposed between the intermediate jigs 350 is repeatedly inserted The position is aligned, and the degree of freedom of rotation can be limited.
