1 and 2, the fine metal collecting apparatus 100 according to the embodiment of the present invention is provided on a conveyor belt 600 for conveying a PCB glass substrate, a film or a panel, , And a block structure for collecting the fine metal dust remaining on the panel 500 such as a film on one surface through a magnetic force.

More specifically, the fine metal collecting apparatus 100 may include a block-type case 110, a cover member 120, a magnetic close circuit 130, and at least two magnet modules 100 and 200.

The block type case 110 is disposed on the conveyor belt 600 and may be made of a material other than a magnetic material, for example, a transparent or translucent acrylic plate. The block-type case 110 includes a body 112 and a suction plate 111.

The body 112 is formed with a receiving space for receiving the cover member 120. The suction plate 111 is formed at one end of the body 112 to be easily detachable through a fastening member A. [ Here, the attracting plate 111 may have a predetermined thickness, preferably a predetermined thickness, to minimize the loss of the magnetic force provided by the pair of magnet modules 230 formed by stacking the magnets 210 and 220 in the cover member 120 Is made to have a thickness within the range of 1 mm to 2 mm. Although the suction plate 111 is described as being detached by the fastening member A, the suction plate 111 may be fixed to the lower surface of the body 112 by an adhesive, or may be welded or welded. To the lower surface of the body 112.

In addition, the attracting plate 111 may be made of any one of aluminum (Al), copper (Cu), and tin (Sn). On the other hand, materials other than magnetic materials such as aluminum (Al), copper (Cu), and tin (Sn) which are less affected by the magnetic force of the magnet are defined as materials other than the magnetic material.

Here, in the embodiment of the present invention, only aluminum (Al), copper (Cu), and tin (Sn) have been exemplified, but any material other than the magnetic material or the paramagnetic material may be used. Preferably, the attracting plate 111 is made of a material other than the magnetic material, so that the attracting plate 111 can be easily removed, and the attracting plate 111 can be easily removed after the attracting plate 111 is removed.

3 (a), in the fine metal collecting apparatus 100, the cover member 120 is provided to prevent corrosion of a pair of symmetrical magnet modules 230 provided inside the cover member 120, And is accommodated in the case 110, and a receiving space for receiving at least one pair of the magnet modules 230 is formed therein.

The at least one pair of magnet modules 230 are inserted into the cover member 120 and spaced apart from each other in such a manner that electrodes of the same polarity are horizontally opposite to each other and are in contact with the magnetic close circuit 130 And is located at the lower part thereof. The magnet module 230 having at least one pair of the magnets is formed so that at least one or more magnets are stacked in the height direction, and the magnets having the same height and spaced apart from each other are arranged to face each other . Further, the polarities of the symmetrical magnets 210 and 220 are arranged with the same magnetic pole.

The magnet module 230 has a stacked structure in which the N pole and the S pole are repeated in the vertical direction and the magnet module 230 is configured such that the same polarity is disposed between the magnets 210 and 220 that are symmetrical in the horizontal direction.

In addition, a partition member 140 may be provided for separating the magnet modules 230 having a laminated structure symmetrical between the pair of magnet modules 230 formed in the receiving space of the cover member 120, The partition member 140 separating the magnet modules 230 when the two or more pairs of the magnet modules 230 are accommodated in the cover member 120 may be disposed.

Here, the thickness of the partition member 140 determines the magnitude of the magnetic flux density generated between the two magnet modules 230, and the magnitude of the magnetic flux density is determined by the thickness of the PCB glass substrate, Film and the like, and the distance between the panel 500 and the fine metal collecting apparatus 100, as shown in FIG.

Referring to FIG. 3 (b), a fine metal collecting apparatus 200 according to another embodiment is shown. 3 (a) is an embodiment composed of a pair of magnet modules, whereas FIG. 3 (b) is another embodiment of configuring two pairs of magnet modules 230 in the cover member 120 . Although three or more magnet modules 230 are shown in FIG. 3, three or more magnet modules 230 may be formed in the cover member 120.

Hereinafter, the magnetic flux densities of the fine metal collecting apparatuses 100 and 200 and the panel 500 according to the embodiment of the present invention will be described.

4 is a view showing a magnetic force distribution in a vertical direction generated in a fine metal collecting apparatus according to an embodiment of the present invention. 5 is a view showing a magnetic force distribution in a vertical direction generated in a fine metal collecting apparatus according to an embodiment of the present invention.

Referring to FIG. 4, since the existing fine metal collecting apparatus arranges different magnetic poles in the horizontal direction, a magnetic force line of a straight line shape and a magnetic line of force of a parabolic line shape are distributed together between adjacent adjacent magnetic poles. However, when the same polarity is arranged between the magnets 210 and 220 arranged to face each other as in FIG. 4, a repulsive force acts. The lines of magnetic force generated in the horizontal direction by the repulsive force between the magnets 210 and 220 are removed and the lines of magnetic force are formed as the upper and lower portions, so that the magnetic force to the panel 500 to be collected increases. Further, the magnet module 230 is formed in a stacked structure of magnets, so that the magnetic force distribution in the vertical direction is flat. This means that it is possible to collect evenly the fine metal that can contaminate the panel 500 to be captured.

5, the fine metal collecting apparatuses 100 and 200 according to the embodiment of the present invention form a parabolic magnetic force distribution in a predetermined vertical direction in the traveling direction of the panel 500 such as a PCB glass substrate and a film This parabolic shape magnetic force distribution is a magnetic force generated between the magnets 210 and 220 in the vertical direction, and therefore does not greatly affect the panel 500 to be collected.

On the other hand, since the magnets having the same polarity in the horizontal direction are opposed to each other in this way, the magnetic force with respect to the downward direction to be collected increases and the collection ability with respect to the fine metal is improved by the increase of the magnetic force. By constructing such a magnet having the same polarity to face each other, a performance improvement of about 20% can be expected.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. will be. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
