Description

Fly products collection device {APPARATUS FOR COLLECTING NON-PRODUCT}

The present invention relates to a non-product collecting device, and more particularly, to a non-product collecting device for effectively collecting fly products generated by cutting the edge of the substrate by a laser.

In general, the laser is irradiated through a laser irradiation device to cut, engrave or partially remove the object.

For example, the display panel may be cut using such a laser, in which case, the polarizing film attached to the surface of the display panel is burned due to the heat of the laser, thereby generating dust and gas.

However, dust and gas generated in this way accumulate in other parts of the equipment to cause malfunction of parts, or floating dust is attached to the display panel again, thereby causing a problem in that the quality of the display panel is deteriorated.

In addition, the dust and gas generated in this way has a problem in that it is difficult to accurately process by interfering with the field of view of the camera to check the cutting position of the display panel.

In order to solve this, by closing the processing chamber in which the display panel is accommodated, and applying a negative pressure from the outside by combining a suction duct on one side of the processing chamber, a dust removal device that absorbs dust and gas generated in the processing chamber and discharges it to the outside I am using it.

However, since the conventional dust removal apparatus adopts a method of stopping the laser cutting process and then performing the cutting process again after performing the laser cutting process in order to perform the dust removal operation, the efficiency of processing is reduced and the processing time is largely consumed. There is this.

As shown in FIG. 4, the first injection unit 200 may have a housing 210 and a nozzle block 220.

The housing 210 may be formed to extend in the longitudinal direction of the substrate DP, and may have an accommodation space 211 inside and an open bottom.

A connection hole 216 may be formed on the upper surface of the housing 210. The first port 230 may be coupled to the upper surface of the housing 210. The first port 230 may supply external air to the accommodation space 211, and the air supplied in this way may be accommodated in the accommodation space 211.

A fastening member (not shown) may be coupled to the connection hole 216, and the fastening member may be coupled to the nozzle block 220 through the connection hole 216, through which the housing 210 and the nozzle block 220 may be combined.

5 is an exploded perspective view showing the second injection unit of the non-product collection device according to an embodiment of the present invention, Figure 6 is an exemplary view showing an operation example of the non-product collection device according to an embodiment of the present invention .

5 and 6, the second injection unit 300 may have a side frame 120 and a cover nozzle 310.

The cover nozzle 310 may be coupled to be in close contact with the outer peripheral surface of the side frame 120. In the state where the cover nozzle 310 is coupled to the side frame 120, the upper portion of the receiving groove 121 based on the receiving groove 121 may be in close contact with the cover nozzle 310.

Meanwhile, the cover nozzle 310 may have a stepped groove 311 formed to be spaced apart from a lower portion of the outer circumferential surface of the side frame 120. The stepped groove 311 may be opposed to the lower portion of the receiving groove 121 based on the receiving groove 121 in a state where the cover nozzle 310 is coupled to the side frame 120, and the outer peripheral surface of the side frame 120 And can be spaced apart. In addition, the spaced apart portion may form a second injection slit 333 between the cover nozzle 310 and the side frame 120.

In addition, a supply hole 312 may be formed through the cover nozzle 310, and a second port (not shown) may be coupled to the supply hole 312. The second port may have the same or the same function as the first port 230 (see FIG. 4 ).

In the state where the cover nozzle 310 is coupled to the side frame 120, air supplied from the outside through the second port can be accommodated in the receiving groove 121 through the supply hole 312, and the second injection slit It can be injected through 333. Since the second injection slit 333 is formed along the side frame 120, air injected from the second injection slit 333 may be injected vertically downward from the outside of the substrate DP.

However, the side frame 120 according to the present invention may have a guide surface 127 at the lower end. The guide surface 127 may be rounded at the lower end of the side frame 120, and the air injected downward from the second injection slit 333 is attached to the guide surface 127 by a Coanda Effect. Can flow. The Coanda effect refers to a tendency for airflow ejected by approaching a certain surface to be sucked and adhered to the surface.

Therefore, the air A2 injected downward from the second injection slit 333 is connected to the second injection slit 333 and is directly connected to the second injection slit 333 to be attached to the guide surface 127 formed to flow. Therefore, it can be induced to move in the rim direction of the substrate DP.

In addition, the side frame 120 may further have an edge surface 128 at the lower end. The edge surface 128 may be formed to form a discontinuous surface with the guide surface 127 at the lower end of the side frame 120. In this embodiment, the edge surface 128 may be formed in a horizontal direction. Accordingly, the air A2 attached and flowing to the guide surface 127 is better separated from the boundary between the guide surface 127 and the edge surface 128, that is, the rear end of the guide surface 127, and the substrate DP You can move in the direction.

Through this, it can be prevented that the air induced by the flow by the guide surface 127 is directly sucked into the first suction passage 411 of the suction part 400. In addition, since the air induced by the flow by the induction surface 127 and the edge surface 128 flows in the rim direction of the substrate DP, it is pushed outward by the air injected from the first injection unit 200. It is possible to prevent the outgoing scattering products from being pushed outward from the first suction passage 411 of the suction part 400. If, if the air injected from the second injection slit 333 moves only vertically downward, the scattered product pushed outward by the air injected from the first injection unit 200 is further outward than the first suction passage 411 Since it can move to, it may be difficult to be effectively sucked into the first suction passage 411. However, in the present invention, since the air injected from the second injection slit 333 can have an air flow symmetrical to the air flow injected from the first injection unit 200, the first injection unit 200 The scattered products pushed by the injected air may be trapped in the vicinity of the first suction passage 411, and through this, it may be effectively sucked into the first suction passage 411. Fly products sucked into the first suction passage 411 may be discharged through the second suction passage 412.
