The pump 127 may include a first connection line 1271 connected to the water tank 120e and a second connection line 1272 connected to the entrance and exit.

The second connection line 1272 may be detachably connected to the entrance so as not to be interfered with when the pivoting bars 122a and 122b are rotated.

When the weight of the workpiece 2 is light, the rotation speed of the rotation bars 122a and 122b may be increased by increasing the weight of the filling box 126 by filling the filling space with water through the pump 127.

When the foreign matter removal operation of the workpiece 2 is completed, the water stored in the filling space may be recovered.

The vibration generating unit 128 generates vibration in the workpiece 2 accommodated in the receiving space of the box units 123a and 123b, and is installed on both side surfaces of the box units 123a and 123b, respectively.

The fluctuation generating unit 128 is made of an elastic material of metal and is formed in a semicircular or hemispherical shape.

The bounce parts 129 are composed of two pairs and are arranged to be spaced apart from each of the box parts 123a and 123b by a predetermined distance.

The bounce part 129 is made of a metal elastic material to bounce off the fluctuation generating part 128, and is formed in a semicircular or hemispherical shape.

It is disposed on the upper side of the pedestal 5 having a certain height of the bounce part 129.

A fixing plate 6 to which the bounce part 129 is fixed is installed on the upper surface of the pedestal 5.

7, one bouncer 129 faces the shaking generating part 128 installed on the left side of the box part 123a located on the left side, and can bounce off the facing shaking generating part 128. there is.

The other bounce part 129 may face the shaking generating part 128 installed on the right side of the box part 123b located on the right side, and bounce off the shaking generating part 128 facing it.

The coil spring 120a is installed on the upper side of one inner wall and the other side wall of the box parts 123a and 123b, respectively.

The push plates 120b are respectively installed on the coil springs 120a.

The intake fan 120c is installed on the upper surfaces of the box portions 123a and 123b, respectively.

The intake fan 120c includes a suction pipe (not shown) passing through the upper surfaces of the box parts 123a and 123b and positioned in the receiving space of the box parts 123a and 123b.

Therefore, in the intake fan 120c, the vibration generating parts 128 collide with each other due to the rotation of the rotation bars 122a and 122b in the left and right directions, and vibration occurs in the workpiece 2 in the box parts 123a and 123b. Due to this, foreign substances separated from the workpiece 2 are sucked.

Although not shown in the drawings, the intake fan 120c may further include a discharge pipe (not shown) connected to a separate foreign matter storage tank (not shown).

Therefore, the intake fan 120c can suck in the foreign substances separated from the workpiece 2 and transfer them to the foreign substance storage tank.

Next, the operation and effect of the removal unit described above will be described.

First, the workpiece 2 is accommodated in the receiving space of each of the box portions 123a and 123b.

At this time, the accommodation space of the box portions 123a and 123b may be formed to have an area capable of accommodating one to five workpieces 2 .

Thereafter, when the weight of the workpiece 2 is light, the box parts 123a and 123b are greatly affected by gravity to increase the rotation speed of the rotation bars 122a and 122b. Filling box through the pump 127 Water is filled in the filling space of (126).

After filling the filling space with water, the second connection line 1272 is separated from the entrance.

After that, one of the box portions 123a and 123b is pushed away from the other box portion 123a and 123b.

For example, based on FIG. 7 , the box portion 123a located on the left side may be pushed in the left direction to separate it from the box portion 123b located on the right side.

Accordingly, the rotation bar 122a in which the corresponding box portion 123a is installed is rotated in a direction away from the other rotation bar 122b facing each other.

Then, when the hand is released from the box portion 123a, the box portion 123a located on the left moves in the direction of the box portion 123b located on the right. That is, the rotation bar 122a moves like a pendulum so that the box portion 123a on the left moves in the direction of the box portion 123b on the right.

At this time, the rotation bar 122a is rotated at high speed in the direction of the opposite rotation bar 122b by its own weight and the weight of the weight part 125 and the filling box 126, and as a result, the box part 123a moves at a high speed. It moves in the direction of the stopped box portion 123b.

Accordingly, the fluctuation generating portion 128 located on the right side of the box portion 123a strongly collides with the fluctuation generating portion 128 located on the left side of the box portion 123b.

Due to this, the rotation bar 122b located on the right is rotated to the right, and the box portion 123b located on the right is moved to the right. In addition, the rotation bar 122a located on the left is rotated to the left again by the collision of the shaking motion generators 128, and the box portion 123a located on the left is also moved to the left.

In addition, the fluctuation generating unit 128 installed on the left side of the box unit 123a located on the left side collides with and bounces off the bounce unit 129 located on the left side, and installed on the right side of the box unit 123b located on the right side The fluctuation generating unit 128 collides with the bouncing unit 129 located on the right side and bounces off.

Accordingly, the pivoting bars 122a and 122b are rotated in a direction closer to each other, so that the box portions 123a and 123b move in a direction closer to each other. As a result, the shaking generating part 128 installed on the right side of the box part 123a located on the left collides with the shaking generating part 128 installed on the left side of the box part 123b located on the right side.

That is, due to the action of the shaking generating unit 128 and the bouncing unit 129 described above, the rotation bars 122a and 122b repeatedly make pendulum movements for a certain period of time.

On the other hand, inside the box parts 123a and 123b, the workpiece 2 oscillates in left and right directions corresponding to the moving directions of the box parts 123a and 123b.

That is, when the workpiece 2 pushes the push plate 120b due to vibration, the corresponding coil spring 120a is compressed and then expanded so that the push plate 120b bounces off the workpiece 2.

Since the coil spring 120a and the push plate 120b are respectively located on one side and the other side of the workpiece 2, the workpiece 2 is repeatedly collided with both push plates 120b and bounced off.

Therefore, an impact is generated on the workpiece 2, and the foreign matter adhering to the workpiece 2 is separated and sucked in by the intake fan 120c. Due to this, it is possible to provide a clean and clean workpiece 2 .

In addition, if necessary, the workpiece 2 is withdrawn from the box portions 123a and 123b, and then reversed 180 degrees up and down to enter the box portions 123a and 123b, thereby removing the workpiece 2 in the above-described manner. Any foreign substances on the bottom of the E can also be removed.

In the laser processing system 1 according to an embodiment of the present invention, when the two rotation bars 122a and 122b are moved as a pendulum in the above-described manner, the workpiece 2 is repeatedly pushed to the push plate 120b for a predetermined time. As a result, the foreign matter buried in the workpiece 2 can be easily and conveniently removed by the action of repeatedly generating an impact force on the workpiece 2 for a certain period of time.
