The sizes and shapes of the components shown in the drawings may be exaggerated for clarity and convenience. In addition, terms defined in consideration of the configuration and operation of the present invention may be changed according to the intention or custom of the user, the operator. 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. The jig device of the present invention may be referred to as a case polishing device for polishing a terminal case while changing directions.

The jig device shown in FIG. 1 may include a sanding unit 100 and a support unit 200.

The terminal case 10 may be supported on one of the sanding unit 100 and the support unit 200 and the other may be supported with a polishing unit 90 for polishing the terminal case 10.

The abrasive portion 90 may include a cloth or paper or a synthetic resin sandpaper impregnated with a powder such as a mortar, a glass powder, a silica, or a metal.

The abrasive portion 90 may be brought into contact with the terminal case 10 to smoothly polish the surface of the terminal case 10 or to peel off the paint layer applied to the terminal case 10. [ The polishing of the terminal case 10 can be performed by rubbing the polishing part 90 against the terminal case 10 or by rubbing the terminal case 10 against the polishing part 90 in this contact state.

In order to automate the polishing process of smoothing the surface of the terminal case 10 or peeling the paint, the contact means for contacting the polishing section 90 and the terminal case 10 with each other, the polishing section 90 and the terminal case 10 Is required to be relatively rubbed.

In the jig apparatus of the present invention, the sanding unit 100 can move the moving member 190 along the first direction and the second direction orthogonal to each other. If the polishing unit 90 is mounted on the moving member 190 or the terminal case 10 is mounted on the moving member 190 in a state where the polishing unit 90 is fixed while the terminal case 10 is fixed, The shifting member 190 may function as a sanding means.

The support unit 200 may be disposed at a position facing the moving member 190. [ Further, it can move relative to the sanding unit 100 along a third direction orthogonal to the first direction and the second direction.

For example, the first direction? May be the z axis, the second direction? May be the x axis, and the third direction? May be the y axis in a hypothetical space where the x axis, the y axis, and the z axis are orthogonal to each other.

The movable member 190 can be moved along the z axis and the x axis by the sanding unit 100. When the polishing unit 90 is detached from the moving member 190, the terminal case 10 can be attached to and detached from the supporting unit 200 moving along the y axis.

The z-axis coordinate and the x-axis coordinate of the terminal case 10 moving in the y-axis by the support unit 200 can be fixed. Therefore, the terminal case 10 moved by the support unit 200 to contact the polishing portion 90 can be rubbed and polished by the polishing portion 90 moving along the z-axis and the x-axis.

The sanding unit 100 can move the moving member 190 in the first direction 1 and the second direction 2 by various methods.

For example, the sanding unit 100 is provided with a first module 110 for moving the moving member 190 in the first direction 1 and a second module 120 for moving the first module 110 in the second direction 2 .

Here, the second module 120 may move the first module 110 provided with the moving member 190 in the second direction 2, instead of moving the moving member 190 directly in the second direction 2. According to this, the moving member 190 can be indirectly moved in the second direction 2 by the second module 120. Hereinafter, the first module 110 and the second module 120 will be described in detail.

2 is a schematic view showing a sanding unit 100 constituting the jig device of the present invention.

The moving member 190 provided in the sanding unit 100 may have a flat plate shape parallel to the imaginary zx plane formed by the z axis corresponding to the first direction 1 and the x axis corresponding to the second direction 2. According to this, the polishing unit 90 provided on the moving member 190 can also maintain a state parallel to the zx plane.

The first module 110 includes a first guide portion 111 extending along the first direction 1 and guiding the moving member 190, a first cam portion 113 for moving the moving member 190, a first guide portion 111 and a first support portion 117 to which the first cam portion 113 is supported. The first module 110 may further include a first connection part 115 having one end connected to the first cam part 113 and the other end connected to the moving member 190.

As shown in Fig. 3, the first cam 113 can rotate with the rotation axis 119 in a direction orthogonal to the first direction?. At this time, when one end of the first connection part 115 is connected to a position separated from the upper rotation shaft 119, the moving member 190 connected to the other end of the first connection part 115 can move in various directions. However, since the movement of the moving member 190 is guided by the first guide portion 111 extending along the first direction 1, the moving member 190 can move along the first direction 1.

The second module 120 includes a second guide portion 121 extending along the second direction 2 and guiding the first support portion 117, a second cam portion 123 for moving the first support portion 117, And a second support portion 127 to which the first cam portion 121 and the second cam portion 123 are supported. The second module 120 may include a second connection part 125 having one end connected to the second cam part 123 and the other end connected to the second support part 127.

The second cam 123 can rotate with the rotation axis 129 as a direction orthogonal to the second direction 2 as shown in Fig. When one end of the second connection portion 125 is connected to the second cam portion 123 at a position spaced apart from the upper rotation shaft 129 similarly to the first cam portion 113, The support portion 117 can flow in various directions. However, the flow of the first support part 117 can be made along the second direction 2 by the second guide part 121. [

3 is a schematic view showing the first cam portion 113. Fig.

The first cam part 113 may be provided with a connecting shaft 118 to which one end of the first connecting part 115 is connected to the rotating shaft 119. At this time, the connection shaft 118 is spaced from the rotation shaft 119, so that the first connection part 115 can flow when the first cam part 113 rotates.

4 is a schematic view showing the second cam portion 123. Fig.

The second cam part 123 may be provided with a connecting shaft 128 to which one end of the second connecting part 125 is connected to the rotating shaft 129. The connection shaft 128 may be spaced apart from the rotation shaft 129 so that the second connection portion 125 may flow when the second cam 123 rotates.

3 and 4, the distance between the connection shaft 118 to which one end of the first connection part 115 is connected and the rotation axis 119 of the first cam part 113 is defined as a first distance W1, and the second connection part 125 Is defined as a second distance W2 between the connection shaft 128 to which one end of the second cam part 123 is connected and the rotation axis 129 of the second cam part 123. [

The rotational speeds of the first cam portion 113 and the second cam portion 123 may be varied depending on the difference between the first distance W1 and the second distance W2.

For example, if the first distance W1 is smaller than the second distance W2, the rotational speed V1 of the first cam portion 113 may be equal to or greater than the rotational speed V2 of the second cam portion 123. [

The magnitude relationship between the first distance W1 and the second distance W2 can be determined by the terminal case 10.

The length of the terminal case 10 is defined as the first direction length L1 in the first direction 1 and the length of the terminal case 10 is defined as the second direction length L2 in the second direction 2.

If the first direction length L1 is shorter than the second direction length L2, the first reciprocating distance T1, in which the moving member 190 reciprocates along the first direction 1 by the sanding unit 100, May be shorter than the second reciprocating distance T2 by which the moving member 190 reciprocates along the second direction (2).

For example, when the terminal case 10 is placed parallel to the floor as shown in FIG. 1, the first direction length L1 may be shorter than the second direction length L2.

In this state, the polishing unit 90 polishes the outer surface of the terminal case 10, but it is preferable that the outer surface of the terminal case 10 does not have a pattern due to polishing. As a result of the experiment, it was confirmed that when the first direction length L1 is shorter than the second direction length L2, the polishing pattern is reduced when the first reciprocation distance T1 is shorter than the second reciprocation distance T2. In addition, if the first reciprocating time corresponding to the reciprocating time of the moving member 190 in the first direction is equal to or shorter than the second reciprocating time, which is the reciprocating time along the second direction, the occurrence of the pattern due to polishing can be minimized .

T1 may be twice the first distance W1 described above, and T2 may be twice the second distance W2. Accordingly, the magnitude relationship between the first distance W1 and the second distance W2 can be determined according to the first direction length L1 and the second direction length L2 of the terminal case 10.

The first round trip time may be determined by the rotational speed V1 of the first cam portion 113 and the second round trip time may be determined by the rotational speed V2 of the second cam portion 123. [

Therefore, V1 may be V2 or more so that the first round trip time is equal to or less than the second round trip time.

Fig. 5 is a schematic view showing a terminal case 10 to be polished in the jig device of the present invention, and Fig. 6 is a schematic view showing a terminal case 10 to be polished in another jig device of the present invention.

In Figs. 5 and 6, the movement of the polishing unit 90, which is operated in accordance with the first round trip time and the second round trip time, is started.

When an arbitrary point P is defined on the polishing section 90, if the first round trip time is shorter than the second round trip time, P can move in a sinusoidal shape as shown in Fig.

If the first round trip time is the same as the second round trip time, P can move in an elliptical shape as shown in FIG. The height of the sinusoidal wave or the elliptical wave is equal to T1, and the width of the wave can be equal to T2.

As a result of the experiment, it was confirmed that when the first reciprocating distance T1 is larger than the first direction length L1 and the second reciprocating distance T2 is smaller than the second direction length L2, the incidence of the pattern due to polishing is lowered.

According to the above-described jig device of the present invention, the means for effectively polishing one surface of the terminal case 10 can be achieved with a simple configuration.

On the other hand, the terminal case 10 may be provided with a plurality of surfaces, and polishing of the plurality of surfaces may be required. Hereinafter, a method of automatically polishing a plurality of surfaces constituting one terminal case 10 will be described.

7 is a schematic view showing a terminal case 10 to be polished in the jig device of the present invention.

As shown in FIG. 7, 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 following problems may occur when the 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.

The jig device of the present invention can smoothly polish the surface of the terminal case 10 having such flatness as described above by using the polishing part 90. Alternatively, the paint can be polished while keeping the surface smoothly in the terminal case 10 when the paint is erroneously painted.

On the other hand, the side surface of the terminal case 10 may also be smoothly polished or peeled off of the paint may be required. The jig device of the present invention can polish the side surface of the terminal case 10 as well as the intermediate surface where the metal region 20 and the resin region 30 coexist. According to this, the paint applied to the side surface of the terminal case 10 can also be polished.

The terminal case 10 may have a plurality of side surfaces different from the intermediate surface. For example, if the terminal case 10 is rectangular, there are four side faces a, b, c, and d.

In order to automatically polish a plurality of surfaces, the moving member 190 or the supporting unit 200 may be provided with a rotation unit 210 in which the terminal case 10 is supported. For example, FIGS. 1 and 8 disclose an embodiment in which the rotation unit 210 is provided in the support unit 200.

8 is a schematic view showing a first operation of the jig device of the present invention.

The first operation may be an operation of polishing the side surface a of the terminal case 10 by the sanding unit 100 and the support unit 200.

In order to polish the side surface a, the support unit 200 may move along the third direction 3 so that the side surface a of the terminal case 10 contacts the polishing surface 90 and then stop.

When the sanding unit 100 is operated in a state where the side surface a is in contact with the polishing surface 90 by the support unit 200, the side surface a is curled by the polishing surface 90 moving along the first direction 1 and the second direction 2 Can be polished.

Alternatively, the side surface a may contact the polishing unit 90 while the sanding unit 100 moves the polishing unit 90 in the first direction 1 and the second direction 2.

When the polishing of the side surface a is completed, the other side, for example, the side bake, can be polished.

The rotating portion 210 can rotate about the rotational axis O orthogonal to the third direction until the side b is faced to the polishing portion 90 in order to polish the side b. It is sufficient that the rotation axis O of the rotation part 210 is orthogonal to the third direction. Preferably, the rotation axis O of the rotation part 210 extends along the first direction?. This is because it is preferable that the polishing surface of the terminal case 10 extends along the second direction 2 in order to reduce the occurrence of the polishing pattern. The polishing surface of the terminal case 10 may extend along the second direction 2 regardless of the rotation of the rotation part 210 when the rotation axis O of the rotation part 210 extends along the first direction 1. This situation is useful when the first reciprocating distance T1 in which the moving member 190 reciprocates along the first direction 1 by the sanding unit 100 is shorter than the second reciprocating distance T2 reciprocating along the second direction 2.

However, the length L2 of the side surface a and the length L3 of the side surface b may differ from each other in the terminal case 10. The rotation part 210 can not rotate the terminal case 10 at the position where the side surface a is polished by the difference in length or the edge formed by the side surface a and the side surface b.

Therefore, the support unit 200 can move the terminal case 10 in a direction away from the polishing unit 90 as shown in Fig.

9 is a schematic view showing a second operation of the jig device of the present invention.

The second operation may be performed by the support unit 200 and the rotation unit 210.

First, the support unit 200 can move the terminal case 10 in a direction away from the polishing unit 90 so that the rotation unit 210 can rotate.

When the terminal case 10 is separated from the polishing unit 90 to such an extent that the rotation is not restricted, the rotation unit 210 may rotate the terminal case 10 such that the side bays face the polishing unit 90.

The support unit 200 can move the terminal case 10 in a direction in which the polishing unit 90 approaches the side b.

If the first operation and the second operation are repeated, all the side surfaces a, b, c, and d of the terminal case 10 can be sequentially polished.

By the way, according to the second operation described above, the edge e of the terminal case 10 is hard to be polished. In particular, this phenomenon can be further exacerbated if the edge e is rounded on a plane.

The supporting unit 200 may be provided with a rotating part 210 and a moving part 230 to polish the edge e of the terminal case 10.

The rotation unit 210 can rotate about the rotation axis O which is supported on the terminal case 10 and orthogonal to the third direction as described above. The moving unit 230 can move the rotating unit 210 along the third direction?.

The moving unit 230 can move the rotating unit 210 along the third direction so that the terminal case 10 contacts the polishing unit 90 regardless of the rotation of the rotating unit 210 .

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

The third operation of Fig. 10 may replace the second operation of Fig.

In the third operation, the terminal case 10 is rotated by the rotation unit 210, and the terminal case 10 is rotated along the third direction so as to be continuously contacted with the polishing unit 90 during the rotation of the terminal case 10 The unit 200 and the sanding unit 100 may move relative to each other. 10 shows an embodiment in which the sanding unit 100 is fixed in the third direction and the support unit 200 is moved.

The terminal case 10 may have a polygonal shape on a plane having two axes as the second direction 2 and the third direction 3.

The rotary part 210 can be stopped when one side of the polygon, that is, one side of the terminal case 10 is polished by the polishing part 90 in a planar manner. When the polishing of one side is completed, the rotation unit 210 may rotate so that the other side of the polygon is polished.

For example, the rotation unit 210 stops when the side surface a of the terminal case 10 is polished, and is rotated so that the side surface b is polished when the polishing of the side surface a is completed.

At this time, the rotary part 210 is supported by the support unit 200 along the third direction 3 along the third direction 3 so that the edges formed by the side surface (side surface) and the side surface (side surface) It is possible to move in the direction away from the portion 90. At this time, if the moving distance of the rotation part 210 is large, a second operation as shown in FIG. 9 can be realized. However, according to the third operation, the distance that the rotary part 210 moves away from the polishing part 90 can be determined within a range in which the edge is in contact with the polishing part 90.

For example, the moving member 190 and the supporting unit 200 can move relative to each other such that J1 and J2 are equal to each other when the rotating unit 210 rotates. J1 is the distance from the rotation axis O to the end of the terminal case 10 in the third direction ③ and J2 is the distance from the rotation axis to the polishing unit 90. [

The terminal case 10 can be always brought into contact with the polishing unit 90 provided on the sanding unit 100 and can be polished to the edge e by means of the polishing unit 90 regardless of the rotation of the rotation unit 210. [

On the other hand, if J2 is smaller than J1 due to the abnormality of the moving member 190 or the supporting unit 200, the rotation of the rotation unit 210 may damage the terminal case 10. [ In order to prevent this, the damping unit 140 may be provided on the sanding unit 100 or the support unit 200.

The damping unit 140 may include an elastic body such as a spring, rubber, or the like that absorbs the pressure applied to the moving member 190 at a predetermined pressure or higher along the third direction. The damping unit 140 may be provided at various positions capable of absorbing the pressure of the moving member 190 applied in the third direction. For example, the damping unit 140 may be installed in the first module 110. Specifically, the damping portion 140 may be interposed between the moving member 190 and the first support portion 117.

Meanwhile, the terminal case 10 may be polished one by one as shown in FIG. However, in order to improve the polishing rate, it is preferable that the plurality of terminal cases 10 are polished together.

For example, when the first direction length of the terminal case 10 is shorter than the second direction length and the third direction length, the plurality of terminal cases 10 can be easily stacked along the first direction. If the object to be polished is the side surface a, b, c, or d rather than the intermediate surface of each terminal case 10, the side surface is exposed to the outside in spite of the laminated state, so there is no difficulty in polishing.

In order to allow the side surfaces of each of the terminal cases 10 exposed in this way to be polished together by the polishing portion 90, means for supporting each terminal case 10 stacked on each other is required.

For example, the jig device of the present invention may include a jig unit 300 in which a plurality of terminal cases 10 are stacked.

11 is a schematic view showing a jig unit 300 constituting the jig device of the present invention.

When the jig unit 300 is provided, the rotation unit 210 supports the jig unit 300 in place of the terminal case 10, and can rotate the jig unit 300. According to this, the side surface of each terminal case 10 stacked by the jig unit 300 can be faced to the polishing unit 90.

The support unit 200 may include a first jig 310 interposed between the terminal cases 10 to prevent the terminal case 10 stacked in a plurality from being disturbed.

When the terminal case 10 is stacked along the first direction, the first jig 310 may be provided with a through protrusion 350 extending in the first direction and penetrating the terminal case 10. [

The through protrusions 350 are formed so that the degree of freedom of rotation of the terminal case 10 with the first direction (z axis) as the rotation axis, the x-axis degree of freedom moving along the second direction, and the y- And may be provided in plural at different positions.

In order to prevent the terminal case 10 from being damaged at this time, the through protrusions 350 are preferably formed at positions facing the through holes provided in the terminal case 10. For example, as illustrated in FIG. 7, the terminal case 10 may have through holes such as a camera hole 31, an illumination hole 33, and a speaker hole 35 formed therein. At this time, the through protrusions 350 may be formed to be inserted into at least two of the camera hole 31, the illumination hole 33, and the speaker hole 35.

The protruding length of the penetrating protrusion 350 may be larger than the thickness of the terminal case 10. [ According to this, the through protrusions 350 passing through the terminal case 10 can protrude from the terminal case 10. The through protrusion 350 protruding from the terminal case 10 may be inserted into the first jig 310 which is additionally provided below or above the terminal case 10.

To this end, the first jig 310 may be provided with a groove-like connection groove 330 to be inserted into the through-hole 350 of the first jig 310.

Fig. 12 is a schematic view showing the first jig 310, and Fig. 13 is a schematic view showing another first jig 310. Fig.

The first surface 311 of the first jig 310 may have a through protrusion 350 protruding in the first direction (z-axis). A groove-shaped connecting groove 330 may be formed on the second surface 312, which is opposite to the first surface 311.

The connection groove 330 may be disposed at the same position as the through protrusion 350 on the second direction (x axis) and the third direction (y axis). In other words, the penetrating protrusion 350 and the connection groove 330 can be formed at the same position in a plan view.

The terminal case 10 may be interposed between the first jig portions 310 when a plurality of the first jig portions 310 are provided. At this time, each of the terminal cases 10 can be aligned with each other by the through protrusions 350 formed in the first jig 310 and the connection groove 330.

The first surface 311 may be the upper surface of the first jig 310 and the second surface 312 may be the lower surface of the first jig 310 as shown in FIG.

The pressing portion 213 can be moved along the first direction by an actuator 215 such as an air cylinder. When the jig unit 300 is mounted on the rotary part 210, the pressing part 213 can be lowered down to press the jig unit 300. When the jig unit 300 is fixed to the support unit 200 by the pressing unit 213, the rotation unit 210 and the movement unit 230 are operated and the side surface of the terminal case 10 provided in the jig unit 300 Can be polished by the polishing portion 90. [

When the polishing of the terminal case 10 is completed, the moving part 230 can move to a distance that the terminal case 10 is separated from the polishing part 90. Thereafter, the pressurizing portion 213 rises upward to release the pressure applied to the jig unit 300.

The operator can remove the jig unit 300 from the rotation unit 210 and mount the other jig unit 300 accommodating the terminal case 10 requiring polishing in the rotation unit 210. [ After the replacement of the jig unit 300 is completed, the pressing unit 213, the rotating unit 210, and the moving unit 230 operate again, so that the polishing operation for the new terminal case 10 can be performed again.

When the polishing is performed by the polishing part 90, particles peeled from the polishing part 90 or the terminal case 10 are generated, and it is difficult to attach the particles to the terminal case 10 at this time. In order to prevent this, the jig device may be provided with a polishing unit (90) or a cleaning unit (500) for sprinkling the cleaning liquid toward the processing surface of the terminal case (10).

The sanding unit 100 and the cleaning unit 500 can be continuously driven not only in the polishing process of the terminal case 10 but also in the replacement process of the jig unit 300 in order to effectively reduce the particles.
