That is, in FIG. 1, 10 is a clean air generator for removing foreign matters such as dust floating in the air, and the generated clean air is a substantially rectangular box booth (box apparatus) 1.
I am trying to fill within 1. Inside the box-shaped booth 11, a foreign matter removing jig 12 is arranged in the central portion, and rollers 13a and 13b are provided in the upper and lower portions. And box booth 1
The hoop-shaped electronic component 15 entered from the hoop inlet 14 on the lower side of 1 is suspended by the rollers 13a and 13b so as to pass through the foreign substance removing jig 12, and is sent out from the hoop outlet 16 on the upper side of the box-shaped booth. There is. Between the roller 13b and the foreign matter removing jig 12, there is a blow-out nozzle 18 for blowing the ionized air 17 toward the hoop-shaped electronic component 15. The dotted arrow 19 indicates the flow of air in the box-shaped booth 11, and the arrow 20 indicates the hoop-shaped electronic component 1.

プ状電子部品１５に異物の再付着を発生させない。In the above structure, the hoop-shaped electronic component 15 entering from the hoop inlet 14 changes its traveling direction by the roller 13b, receives the ionized air 17 from the blowing nozzle 18, and removes the static electricity on the surface of the hoop-shaped electronic component 15. After the softening, these foreign matters are removed in the foreign matter removing jig 12, the traveling direction is changed again by the roller 13a, and the foreign matter is sent out from the hoop outlet 16. At this time, the box-shaped booth 11 is filled with clean air from which foreign substances such as dust have been removed by the clean air generator 10, and clean air is blown out from the hoop inlet 14 and the hoop outlet 16 as shown by arrows 19. It has occurred. Therefore, inflow of external air mixed with dust or the like does not occur, and reattachment of foreign matter does not occur on the hoop-shaped electronic component 15 after passing through the foreign matter removing jig 12.

せない。By doing so, the hoop-shaped electronic component 15 that has received the ionized air 17 and neutralized the static electricity before the foreign matter removing jig 12 moves in the foreign matter removing jig 12 in the direction of the arrow 20. At this time, air is sequentially received from the air blowout nozzles 12c, 12d, 12e installed at different angles, whereby the air pressure is sufficiently applied to every corner of the cavity 15a, and the cavity 15a
It is possible to remove foreign matter at any position within a. At this time, the air blowing nozzles 12c, 12d,
Since the foreign matter removed by the suction nozzle 12b is discharged to the outside of the foreign matter removing device 12 at a flow rate three times or more as large as the air flow rate from 12e, an air flow as indicated by arrow 19 is generated, and the removed foreign matter is removed. Almost no redeposition occurs.
