Fig. 2 is a plan view for explaining a thin plate material which is processed by being placed on a vacuum chuck for cutting a unit workpiece.

As shown in these drawings, a vacuum chuck for cutting a unit work according to an embodiment of the present invention (hereinafter referred to as a vacuum chuck) includes a lower base 100, an upper base 200 and a hole pad 300, .

This will be explained in more detail for each configuration.

First, the lower base 100 is a portion fixed to the upper surface of a work table (not shown) while forming a lower body of a vacuum chuck according to an embodiment of the present invention.

The lower base 100 includes a frame 110 fixedly mounted on the upper surface of the work table. In addition, the upper surface of the inner portion includes a space for air flow (hereinafter referred to as "air flow space"), (Not shown).

Further, a vacuum groove 130 is additionally recessed in the front side portion of the inner upper surface of the lower base 100. The vacuum groove 130 provides a space for providing a vacuum suction force separate from the air flow space. The vacuum groove 130 is connected to a vacuum suction pipe 140 through a front surface of the lower base 100, .

A plurality of air flow holes 120 are formed in the inner upper surface of the lower base 100 so as to uniformly transfer the vacuum suction force inside the vacuum groove 130 to the entire air flow space 120. [ And guides 150 are formed to protrude.

Particularly, in the embodiment of the present invention, the vacuum suction pipe 140 is connected to one side of the vacuum groove 130 and the other side of the vacuum groove 130 is connected to one end So that they are spaced apart from each other. That is, since the communication part between the respective flow guides 150 is positioned as far as possible from the connection part of the vacuum suction pipe 140, the vacuum suction force provided through the vacuum suction pipe 140 is transmitted to the respective flow guides 150, So as to be provided as uniformly as possible.

In addition, in the embodiment of the present invention, each of the channel guides 150 is arranged in a fan-like structure that gradually flares from one end to the other end of the channel guide 150. In addition, And is arranged to be spaced apart from the inner circumferential wall surface. Through this structure, it is possible to provide a uniform vacuum suction force to the entire air flow space of the lower base 100.

Next, the upper base 200 closes the open top of the lower base 100 while forming the upper body of the vacuum chuck according to the embodiment of the present invention.

The upper base 200 is formed as a block body and fixed on the upper side of the lower base 100. A plurality of vacuum holes 210 are vertically formed in the upper side of the upper base 200 .

At this time, a sealing member (for example, an O-ring or the like) 160 is provided on the upper surface of the outer periphery of the lower base 100 so that a contact portion with the upper base 200 can be hermetically sealed.

Particularly, in the upper surface of the upper base 200, a plurality of concave grooves 220 are formed in a lattice structure around the respective vacuum holes 210, and the upper surface of the upper base 200, A plurality of extension grooves 230 communicating with the concave grooves 220 adjacent to the vacuum holes 210 are formed in the periphery of the vacuum hole 210. [ The recessed groove 220 and the extended groove 230 are regions for expanding the area of the vacuum suction force transmitted through each of the vacuum holes 210.

That is, even if the number of the vacuum holes 210 is minimized through the shape of the concave grooves 220 and the plurality of the extension grooves 203, a uniform vacuum suction force in a wide range can be provided, The number of the holes 210 can be reduced, and the vacuum chuck can be manufactured more easily.

Next, the hole pad 300 is a region where the unit workpieces 11 cut from the thin plate material 10 can stably be vacuum-adsorbed at the corresponding positions even after the unit workpieces 11 are cut.

The hole pads 300 are mounted on the upper surface of the upper base 200 to cover the respective vacuum holes 210 and have a pad structure on the upper surface of which a single thin plate material 10 is placed. .

Particularly, in the embodiment of the present invention, the hole pads 300 are formed of a mesh body having a minute gap formed of a material such as paper or non-woven fabric, It is possible to smoothly perform vacuum suction even for a thin plate material placed on a part of a workpiece, and furthermore, air can be introduced, but the inflow of the foreign matter is blocked so that a foreign substance such as a chip, Thereby preventing the vacuum hole 210 from being blocked.

That is, since the hole pads 300 are formed in the structure of the fine mesh body, the vacuum suction force provided through the respective vacuum holes 210 is concentrated not only at the positions where the vacuum holes 210 coincide with the corresponding vacuum holes 210, The entire area of the thin plate material 10 placed on the hole pads 300 can be uniformly delivered to the vacuum hole by uniformly dispersing the holes to reach a part of the periphery of the holes 210.

Hereinafter, the cutting process of the unit work 11 using the vacuum chuck according to the above-described embodiment of the present invention will be described in more detail.

6, a vacuum chuck according to an embodiment of the present invention includes an upper base 200 mounted on an upper surface of a lower base 100 and fixed with a bolt (not shown) The hole pads 300 are placed on the upper surface of the upper base 200 so that the vacuum holes 210 are closed from the external environment as shown in FIG. A single thin sheet material 10 to be processed is placed on the upper surface of the hole pads 300.

In this state, when the vacuum suction pipe 140 is provided with a vacuum suction force, the inside of the vacuum chamber 130 of the lower base 100 is evacuated by the vacuum suction force, and the inside of the vacuum chamber 130 is positioned so as to communicate with the inside of the vacuum chamber 130 The air flow space 120 between the respective flow guides 150 is also evacuated.

At this time, since the portion where the vacuum suction pipe 140 is connected to the vacuum groove 130 and the portion communicating with the flow guide 150 are far apart from each other, the vacuum suction force between the specific flow guides 150 The vacuum suction force is uniformly applied to the entire area between the respective flow guides 150 while being prevented from being concentrated. Further, considering that each of the channel guides 150 is formed so that the distance therebetween gradually increases toward the other end, and the end surface of the other end is spaced apart from the inner wall surface of the lower base 100, 150 can be made to be uniformly evacuated.

When the air flow space 120 is evacuated as described above, a vacuum suction force is generated on the upper surface of the upper base 200 through the vacuum holes 210 formed to communicate with the air flow space 120.

At this time, the vacuum suction force generated on the upper surface of the upper base 200 is provided as a plurality of extension grooves 230 formed along the vacuum hole 210 on the upper surface of the upper base 200, The hole pad 300 is vacuum-absorbed by the hole pad 300. In particular, considering that the hole pad 300 has a structure of a mesh body having minute gaps, So that the entire thin plate material 10 placed on the upper surface of the hole pad 300 is supplied with vacuum suction force which is provided through the hole pad 300.

Therefore, during the cutting operation for the plurality of unit workpieces 11 through the processing of the thin plate material 10, the thin plate material 10 is pressed by the vacuum suction force provided through the hole pads 300, A stable vacuum adsorption state can be maintained on the upper surface of the pad 300.

Further, during the cutting of a unit work 11, a vacuum force is leaked through a gap in the cut portion. However, even if leakage of the vacuum force occurs, the unit work 11 The unit workpiece 11 is kept in a state of being vacuum-absorbed without being detached from the hole pad 300. As a result, the separation of the unit workpiece 11 It is possible to prevent the vacuum breakdown phenomenon caused by the vacuum evaporation.

As a result, the vacuum chuck according to the embodiment of the present invention can provide the vacuum chuck 130 and the channel guide 150 with the same structure as the vacuum chuck 130, the surrounding structure of the vacuum hole 210, The stable vacuum absorption of each unit workpiece 11 can be maintained while cutting a plurality of unit workpieces 11 from the substrate 10 so that the flow of the thin plate material 10 due to unwanted vacuum release and the flow of each unit workpiece 11 11 can be prevented from flowing, thereby enabling precision machining of each unit work 11.

In addition, the hole pads 300 of the vacuum chuck according to the embodiment of the present invention also function as a filter for preventing fine foreign substances generated during cutting work on the unit work pieces from entering the vacuum holes 210, The hole pads 300 can be prevented from being damaged when the cutting process of each unit work piece 11 to one sheet material 10 is completed. Since only the hole pads 300 are replaced without cleaning the lower base 100 or the upper base 20 after the cutting process, the preparation time can be shortened as much as possible .
