Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a multi-tank cleaning device used for cleaning disk-shaped objects to be cleaned.

[Prior Art] For example, when cleaning an aluminum disk used as a memory board for a computer, a multi-tank method is generally used to sequentially perform ultrasonic cleaning, cold liquid cleaning, steam cleaning, etc. using organic solvents and water. Cleaning equipment is used. However, when cleaning a disk that has been wrapped or polished, it is first cleaned with a brush to remove adhering dirt, abrasives, etc., and then finished using the multi-tank cleaning device described above. It is advisable to wash it.

However, in the conventional cleaning equipment described above, it is impossible to perform such brush cleaning and final cleaning using an organic solvent or water at the same time.
For this reason, the disks were first treated with a scrubber cleaning device equipped with a separate brush and then finished cleaned with the multi-tank cleaning device mentioned above, but now the disks are processed continuously in one cleaning line. It is very difficult and time-consuming to clean the disks, and furthermore, the conventional scrubber cleaning equipment can only process one disk at a time, making cleaning very inefficient and difficult for mass production.

[Problems to be solved by the invention] In view of the above-mentioned conventional drawbacks, the present invention configures a multi-tank cleaning device with a scrubber cleaning function, and simultaneously processes a large number of disk-shaped objects to be cleaned. The technical challenge is to configure it so that it can be done.

[Means for Solving the Problems] In order to solve the above problems, the multi-tank cleaning device of the present invention includes a plurality of cleaning tanks for cleaning disk-shaped objects to be cleaned, and a plurality of cleaning tanks for accommodating the objects to be cleaned. In a multi-tank cleaning device, the carrier is provided with an engaging groove in which the outer circumference of the object to be cleaned is fitted, and a conveying means for conveying the carrier sequentially to each cleaning tank. By arranging a plurality of support rollers with intervals in a concave step shape, these support rollers can support a large number of objects to be cleaned in a vertically lined state, and the plurality of cleaning tanks A part of the scrubber cleaning tank is used as a scrubber cleaning tank, and in the scrubber cleaning tank, a plurality of brushes each having a large number of protruding rubbing pieces attached to both sides of a disc-shaped substrate are placed at a predetermined distance from each other. , is disposed so as to be able to swing and rotate freely between a cleaning position that fits between the objects to be cleaned supported by a carrier and a standby position that is separated from the objects to be cleaned, and is in contact with the outer surface of the object to be cleaned. A drive roller is provided to drive and rotate the object to be cleaned.
It is characterized by this.

[Operation] A large number of objects to be cleaned housed in the carrier are sequentially conveyed together with the carrier through each cleaning tank by the conveying means, and are subjected to predetermined cleaning in each cleaning tank.

Particularly in the scrubber cleaning tank, each brush rotates to the cleaning position where it fits between the objects to be cleaned, and the rubbing pieces on both sides of the brush slide against the objects to be cleaned on both sides to perform cleaning. Since the scrubbing piece slides not only on the side surface of the object to be cleaned, but also on the outer circumferential surface and the inner circumferential surface of the center hole, dirt on the outer circumferential surface and the inner circumferential surface is reliably cleaned.

[Effects of the invention] According to the invention, some of the cleaning tanks in a multi-tank cleaning device are made into scrubber cleaning tanks using brushes, and a common carrier is used for other cleaning tanks that use organic solvents or water. Since it is configured so that a large number of items to be cleaned stored in the carrier can be cleaned simultaneously in the scrubber cleaning tank, it is now possible to realize a line that combines scrubber cleaning and final cleaning using organic solvents or water, which was difficult in the past. can.

In addition, the carrier is configured to support the object to be cleaned on the outer periphery with a plurality of support rollers provided with engagement grooves, and a large number of protrusions are installed on both sides of the disk-shaped substrate in the scrubber cleaning tank. A plurality of brushes each having a rubbing piece attached thereto are provided, and these brushes are inserted between the objects to be cleaned for cleaning. It also slides securely onto the outer circumferential surface and the inner circumferential surface of the center hole, making it possible to cleanly remove dirt from these outer circumferential surfaces and inner circumferential surfaces.
