An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic perspective view of a clean room in which a dust collecting device according to the present embodiment is installed, FIG. 2 is a perspective view showing a front surface of the dust collecting device according to one embodiment of the present invention, and FIG. It is a perspective view showing the back of the dust collector concerning this example.

1 includes a thick film printing process, a bare chip mounting process, and the like, and a clean room (work) in which a dust collecting device 3 is installed so that dust does not adhere to electronic components such as a thick film integrated circuit 2 to be processed. Table). In the clean room 1, predetermined air conditioning is performed, and dust collecting devices 3 are installed at several places near a thick film integrated circuit 2 on which thick film printing and bare chip mounting are performed. As shown in FIG. 2, the dust collecting device 3 includes a charging plate 4, a support bar 5 for the charging plate, a sliding portion 6, a sliding portion driving device 7, and the like.

The charging plate 4 is formed of a plastic plate material that easily generates static electricity, and has a large number of through holes 41 (for example, in a matrix). The support bar 42 of the charging plate 4 is formed of an insulating material so that static electricity charged on the charging plate 4 does not leak, and supports the charging plate 4 from both sides. The sliding portion 5 has a rod-like shape, and the bristle 51 of the brush and the handle 5 of the brush that slide on the back surface of the charging plate 4.
2 is comprised. The bristles 51 of the brush are formed of a plastic material, and the handle 52 of the brush is formed of an insulating material so that static electricity does not leak. The driving device 6 for driving the brush bristles 51 and the brush handle 52 of the sliding portion 5 is composed of a motor or the like as shown in FIG. 3, and is attached to one end (the lower end in the figure) of the brush handle 52. I have.

Next, the operation of the dust collecting apparatus having the above configuration will be described. In the dust collector 3, the motor 6 is attached to the lower end of the sliding part 5, and the brush bristles 51 of the sliding part 5 are attached so as to slide on the back surface of the charging plate 4. Then, when a printing process or the like is performed, if a switch (not shown) is operated, the sliding portion 5 slides left and right while rubbing on the charging plate 4 by the rotating driving force of the motor 6 (arrow A). This is such that the sliding part 5 rotates right and left so as to draw an arc around the lower end of the sliding part 5 so that the wiper of the automobile slides on the windshield. This driving is performed continuously or intermittently in accordance with the charging ability of the charging plate 4.

Around a work table such as a work table or a belt conveyor in a thick film printing process, the charging plate 4 is installed so as to face the thick film integrated circuit 2 to be processed in the vicinity. When the plastic charging plate 4 and the bristle 51 of the brush of the sliding portion 5 are rubbed, static electricity is generated on the charging plate 4, so that dust adhering to the thick film integrated circuit 2 is attracted to the charging plate 4. And adhere to the surface. Therefore, adhesion of dust to the thick film integrated circuit 2 is prevented.

Since the charging plate 4 is provided with a large number of through holes 41, the friction area is enlarged, and the surface of the charging plate 4 is more strongly charged. Thereby, the adsorption capacity is improved. Further, dust adhering to the charging plate 4 is periodically removed by a vacuum cleaner or the like. According to the present embodiment as described above, static electricity can be generated by rubbing an easily charged plastic material, and floating dust can be adsorbed.

In this embodiment, the motor 6 is directly attached to the sliding portion 5 for sliding the charging plate 4, and the sliding portion 5 is slid so as to draw an arc. The driving device 31 is shown in FIG. As described above, the slide guide 7 may be provided on the sliding portion using the rodless air cylinder 61 or the like, and the sliding portion 8 may be slid left and right (arrow B) to charge. Also, the back surface of the charging plate 4 may be roughened to increase the friction coefficient between the bristles 51 of the brush and the back surface, thereby improving the charging ability.

[0016]

As described above, according to the dust collecting apparatus and the system according to the present invention, it is possible to air-condition a room without considering the intake / exhaust balance in a work room, especially in a clean room, and it is not necessary to perform labor. At least, dust in the room can be easily removed by friction of plastic, which easily generates static electricity.
