An example of such a dust collector is disclosed in Korean Patent Registration No. 10-0724105. According to the dust collector of the prior art, by installing a bottom plate in order to have a suction space in the lower part of the work table on which the circuit board to be processed is placed, the vacuum pressure generating unit (vacuum cleaner) connected to the suction space and suction tube is operated. It has a configuration that collects and recovers the cutting tips generated during machining on the table.

However, according to the prior art as described above, since the suction space is secured so as to have a width corresponding to the entire width of the work table (jig) on which the substrate is placed, the vacuum pressure generator has a large capacity. There is a problem.

In addition, since the suction space is large, there is a problem in that the cutting chips of the printed circuit board placed on the work table cannot be sucked and recovered effectively.

In particular, although the cutting process is made at a specific position of the printed circuit board placed on the work table, since the suction force is generated for the entire area, the suction force is lowered, and there is a limitation in that the cutting chip is not effectively sucked.

In this case, the cutting position of the printed circuit board 10 processed by the cutting bit 231 may be adjusted by driving each of the Y-axis driving unit 235 and the 2-axis driving unit 240.

The jig 210 is formed with a dust collecting hole 211 for transmitting a vacuum pressure so that the cutting chip is discharged to the lower portion is collected.

The dust collecting head member 110 includes a suction head 111 and a suction pipe 113 connected to a lower portion of the suction head 111. The suction head 111 has a venturi hole 111a whose inner diameter is narrowed from the top to the bottom. In addition, the suction head 111 is formed with a cyclone guide hole 111b penetrating from the outer surface to the inner circumferential surface of the venturi hole 111a.

The dust collecting hose 140 may be formed of a flexible material, and may have a freely deformable structure, for example, a bellows structure, in a predetermined section. In addition, one end of the dust collecting hose 140 is fixed in the hose coupling portion 123, and is connected to the lower end of the suction pipe 113 to transfer the suction force. At this time, even if the dust collecting head member 110 is moved up and down, a predetermined section of the lower end of the suction tube 113 is maintained in the dust collecting hose 140 so that the connection state between the dust collecting hose 140 and the suction pipe 113 can be maintained. It enters one end and fits into the distance beyond the lifting movement range. Of course, the dust collecting hose 140 and the suction pipe 113 may be connected by a flexible hose (including a bellows structure).

The second driving unit 160 is for reciprocating the moving block 120 on the X axis. As an example of such a second driving unit 160, the guide block 161 is installed in the lower portion of the processing apparatus main body 210, and the guide block 161 is rotatably installed to rotate the moving block 120 during rotation. A lead screw 163 for moving in the X-axis direction and a drive motor 165 for driving the lead screw 163 in the forward and reverse directions may be provided.

The drive motor 165 is operated in conjunction with the drive signal of the X-axis drive unit 245, thereby moving the position of the dust collecting head member 110 in accordance with the movement position of the cutting bit 231, The cutting chips generated during the cutting process can be effectively sucked and recovered.

That is, according to the dust collector 100 of the present invention, unlike the conventional, by minimizing the suction area of the dust collection head member 110, the suction force to the suction head 111 can be maximized, the vacuum pressure generating unit ( 130) can be reduced. Furthermore, the suction head 111 of the dust collecting head member 110 has a venturi structure, and the cyclone guide hole 111b is formed to maximize the suction force by the cyclone phenomenon. Therefore, by applying a small capacity suction generating unit to generate the maximum suction force can improve the dust collection efficiency.
