Abstract

<P>PROBLEM TO BE SOLVED: To make adjustable suction openings and a suction section area of a suction nozzle in a simple method. <P>SOLUTION: Since the respective suction openings formed by layering slit plates 30 having slits 31 and punched holes 32 and packing plates 20 having punched holes 21 comprises plate thickness t and slit widths 33 of the slit plates 30, the adjustment is not required, and the suction section is calculated by totaling up the respective suction openings. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to cleaning and drying of a flat object such as a metal mask used for board mounting or a screen mask used for silk printing, etc., and is generated by connecting to an electric suction machine or ejector via a pipe. The present invention relates to a suction nozzle that performs suction cleaning or suction drying using negative pressure.

  Until now, suction nozzles incorporated in mask cleaners have been suctioned by using blowing slit nozzles. In particular, a variable slit nozzle that can vary the slit width in a wide and narrow manner is convenient, but it takes time to adjust the slit width. Or, there is a defect such as loosening for screwing, and adjustment after incorporation into a mask cleaning machine is difficult.

  There are other methods of making a slit hole in a tube or a thick plate and using it as a suction hole, or sucking it by combining parts so that it becomes a slit, but these have a fixed slit width Therefore, when adjusting the suction cross-sectional area, it was necessary to replace the nozzle itself.

  It is difficult to adjust the size of the suction hole and the suction cross-sectional area.

  Each suction hole 34 formed by overlapping the slit plate 30 having the slit shape 31 and the punched hole 32 and the packing 20 having the punched hole 21 is constituted by the thickness t and the slit width 33 of the slit plate 30. Therefore, it becomes a reliable dimension, and the adjustment of the slit width, which is conventionally required for the variable slit nozzle, is not necessary.

  Therefore, the dimension or suction cross-sectional area of the suction hole can be easily adjusted by adding, removing, or replacing the slit plate 30 having a different slit width 33 or thickness t.

  The gas or liquid sucked from each suction hole 34 passes through the slit shape 31 from X, and passes through the punched hole 21 of the packing 20, the punched hole 32 of the slit plate 30, or both, and the base 41. It is sucked from the connection port 42 attached to the bottom surface of.
