In particular, the present invention relates to a routing device having an integrated dust collecting device capable of efficiently collecting dust generated during a routing operation. It is about.

In general, a routing device is a device used to manufacture a printed circuit board, etc., and is a device that cuts the same pattern formed on the printed circuit board and separates each strip.

That is, the printed circuit board is composed of a plurality of unit panel combinations, and each unit panel is interconnected by a bridge, and a device for performing a job of cutting the bridge to produce a required unit panel is a routing device.

Such a routing device is provided with a jig table for fixing a printed circuit board, a routing bit for separating the same pattern of the printed circuit board from each other, a spindle motor for high-speed rotation of the routing bit, and the like. Routing is performed by cutting the printed circuit board properly by using the routing bit rotating at a high speed in the state.

In general, since a printed circuit board is cut by a routing bit that rotates at a high speed, a large amount of dust is generated. There is a problem in that the working environment is poor due to such dust.

In consideration of this, most of the routing devices are equipped with a dust collector that can handle the dust generated during the routing operation.

As an example, Korean Patent No. 10-0945391 discloses a "router" having a dust collecting module capable of collecting cutting chips generated at a work stage.

However, since the router is a method of inhaling and discharging dust only by a simple duct facility composed of a combination of a dust collecting duct, a collecting duct, a dust collecting motor, etc., the dust collecting efficiency is not only lowered but also the dust is discharged to the outside. There is a disadvantage that a treatment facility is required.

As another example, Korean Registered Room No. 20-0380212 discloses a dust collector provided in a router of a printed circuit board.

However, since the dust collector is a method of simply inhaling dust generated during routing work by driving a motor inside the dust collector, it is also disadvantageous in terms of efficiency of dust treatment, and the dust collected in the dust collector is collected again. The work is cumbersome and inconvenient, such as the need to collect.

Accordingly, the present invention has been made in view of this point, and the dust generated during the routing operation is sucked into the turbo blower to effectively separate and collect the fine dust in the cyclone, and then continue to collect in a plastic bag. It is an object of the present invention to provide a routing device having an integrated dust collecting device capable of increasing dust collecting power from a routing work area and improving dust removal efficiency by implementing a new dust collecting method.
