DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. The examples described below are
Since it is a preferred specific example of the present invention, various technically preferable limitations are attached, but the scope of the present invention is, unless otherwise stated to limit the present invention, in the following description.
It is not limited to these modes.

FIG. 1 shows an automatic cleaning device for a slicer, which is a preferred embodiment of the work cleaning device of the present invention. This cleaning device is also called an automatic cleaning system. In FIG. 1, the work cleaning device 2 is arranged near the slicer 1 for slicing the work W. In this work cleaning device 2, there is an increasing demand for high-precision machining even in machining with a slicer, and the number of cases in which a work shape is measured on a slicer using a measurement unit such as image processing is increasing. Therefore, if dirt such as dust adheres to the work after being put into the slicer and finished processing,
It causes problems in measurement. In addition, there is an increasing demand for unmanned processing in slicer processing. Therefore, the work cleaning device 2 is developed based on these requirements, and the work can be reliably cleaned on the slicer.

The work cleaning device 2 has the following structure. The table 3, which is a holding unit for holding the work, can be moved in the directions of the arrow X and the arrow Y by a driving unit (not shown). The arrow X is the horizontal direction in FIG. 1, and the arrow Y is the direction perpendicular to the paper surface of FIG. A work W is detachably fixed on the table 3. This work W is, for example, a block and a substrate for making chips of a magnetic head. The block and substrate are sliced by the diamond wheel 20 of the slicer to make a magnetic head chip. A two-fluid spraying means 4 is arranged above the table 3. The two-fluid spraying means 4 has a two-fluid spray nozzle 5, a grinding water supply source 6, and an air supply source 7.

The grinding water supply source 6 is for supplying grinding water to the two-fluid spray nozzle 5 side. The air supply source 7 is for supplying air to the two-fluid spray nozzle 5 side. The driving of the grinding water supply source 6 and the air supply source 7 is controlled by the control unit 10. Further, the control unit 10 can control the movement of the table 3 in the X direction and the Y direction. The two-fluid spray nozzle 5 is, for example, a two-fluid fine spray nozzle, and various tip shapes of the nozzle can be used. Two
There are two types of fluid blown out from the holes of the fluid spray nozzle 5, two fluids, grinding water and air, and only air.

Next, the slicer 1 will be described. The grindstone 20 is detachably attached to the spindle 21. The spindle 21 can be rotated in the direction of arrow R by a drive unit 22 such as a motor. Whetstone 20
Is a diamond wheel, for example, for slicing the work W. The slicer 1 can move up and down in the arrow Z direction. The arrow Z is a direction perpendicular to the X and Y directions. The slicer 1 is preferably movable in the X and Y directions. The arrow X direction is the horizontal direction in FIG. 1, and the arrow Y direction is the vertical direction on the paper surface.

Next, the operation of the above-mentioned slicer 1 and the work cleaning device 2 of the slicer 1 will be described. The work W is mounted on the table 3. The slicer 1 is moved in the direction of arrow X to position the work W under the two-fluid spray nozzle 5. The control unit 10 supplies the grinding water supply source 6
Then, the air supply source 7 is operated, and first, the two fluids S of grinding water and air are simultaneously blown out from the two-fluid spray nozzle 5 onto the work W. The grinding water is vigorously sprayed onto the work W by the air pressure, and dirt such as dust on the work W can be blown off.

Usually, since the water pressure of the grinding water is low, even if the grinding water is directly attracted to the work W, the cleaning effect cannot be expected. Therefore, the grinding water is strongly sprayed onto the work W by utilizing the air pressure. This enhances the effect of cleaning the dirt on the work W.

Next, the grinding water attached to the work W is transferred to the work W.
The controller 10 controls the grinding water supply source 6
Then, the control unit 10 drives only the air supply source 7 to blow only air from the two-fluid spray nozzle 5 onto the surface of the work W. Thereby, the grinding water on the surface of the work W can be completely blown off. With the above work, the work can be automatically washed, but since the grinding water is sprayed on the work with air pressure to remove dirt,
It is possible to reliably remove dirt such as dust attached to the work that cannot be removed only by air. Further, when the cleaning range of the work W is wide, for example, the work W can be cleaned in a wide range by moving the table 3 in the X-axis and Y-axis directions.

In the embodiment of the present invention, the work is put into the slicer 1, the work is sliced, and the automatic cleaning of the work W can be surely performed after the processing is completed. In such a work cleaning device, impurities are not mixed in the grinding water because the grinding water and air are used for automatic cleaning.

The present invention is not limited to the above embodiment. The grinding liquid for cleaning the work W is not limited to the grinding water, and other kinds of grinding liquid can be adopted. For example, tap water can be used. Move the slicer 1 in XY and Z directions, or move the table 3 side to X
The work W can be moved relative to the slicer 1 by moving the work W in at least one of the Y direction and the Z direction. The processing means for the processed work is not limited to the slicer, and the work cleaning apparatus of the present invention can be applied to other means.

[0016]

As described above, according to the present invention, the work can be automatically and surely cleaned.
