was forced to return to

As described above, when the disk member 9 that has been cleaned returns to the work section A and the transfer handler 13 is displaced toward the rotary table 14, the disk member 9 is chucked by the transfer handler 13. .

The cleaned disk member 9 is transferred to the carry-in handler 11, and transferred to the drying section 8, where it is dried by high-speed spin drying or the like. The disk member 9 dried in this way is transferred to the transfer handler 13 by the operation of the transfer handler 13, transferred to the transfer handler 13 by the rotation of the transfer handler 13, and then transferred to the transfer handler 3, and then transferred to the transfer handler 13 by the rotation of the transfer handler 13. The handler 3 rotates to place it in the carry-out rack 4. By sequentially repeating this operation, the disk member 9 is cleaned, and by transporting the carry-out rack 4 to the outside from the carry-out section 5, the disk member 9 that has been completely cleaned is taken out.

In the above-described embodiments, the cleaning tool of the cleaning member was formed in an annular shape, but a cylindrical cleaning tool may be used instead. Further, the cleaning member may not only be brought into contact with both surfaces of the disk member, but may also be brought into contact with only one side. Furthermore, the chuck member was installed on a rotary table, but this was because the disc member was cleaned in multiple cleaning processes. It can also be installed on a member.

[Effects of the Invention] As described in detail above, the present invention allows the cleaning member to clean the disc member while the disc member is rotatably chucked by the chuck member, and the cleaning member does not need to be rotated during cleaning. Since the cleaning liquid is supplied to the interior of the disk member, foreign matter such as abrasion particles adhering to the surface of the disk member can be completely removed without getting stuck between the disk member and the cleaning member. The entire surface of the disc can be automatically cleaned smoothly and reliably, and it can be cleaned with an appropriate liquid film formed on the surface of the disc member, so there is no risk of the disc member being damaged by foreign objects or the cleaning member. .
