  In the cleaning apparatus configured as described above, the operation panel 6 determines the start and end of work and various setting values during the work, and the control panel 4 passes the actuator 16 based on the operation of the operation panel 6. Opening / closing control of the opening 2a by the closing lid 14, temperature management of the cleaning water when supplied to the cleaning chamber 1, control of the rotation direction and rotation speed of the rotary table 17, and supply of the air by the air supply device 8A -Stop control and supply / stop control of washing water by the pre-purified water supply device 8B are performed.

  A specific work procedure will be described. The cleaning work is performed in a state where the opening 2 a is closed by the opening / closing lid 14. During the cleaning operation, the rotary table 17 is rotated in a state where the workpiece W is positioned and mounted on the mounting portion 19, and cleaning water is sprayed onto the rotating workpiece W by the cleaning water supply device 8 </ b> B. The first operation to be performed and the second operation to inject the air with the air supply device 8A are performed in this order.

  First, in the first work, forward rotation for rotating the workpiece W at a predetermined time (5 seconds in this example) and a predetermined speed (30 rpm in this example) on one side (forward rotation side), and the other side (reverse rotation side). And a reverse drive for rotating the workpiece W at a predetermined speed (30 rpm in this example) for a predetermined time (5 seconds in this example). The temperature of the washing water at this time is set to 40 ° C. or less, and this washing water does not include a detergent, and simply uses water as it is.

  At this time, the cleaning water is injected so that the cleaning water is jetted into the hole, the concave portion or the like of the workpiece W in addition to the optimum adjustment of the distance between the cleaning water injection nozzle 34 and the workpiece W by exchanging the tip side pipe 39A. The jet direction of the cleaning water is adjusted by swinging the jet nozzle 34A. By these adjustments and switching of the rotation direction of the rotary table 17, the pre-purified water is efficiently injected over the entire workpiece W.

  Subsequently, in the second operation, forward rotation driving for rotating the workpiece W at a predetermined time (5 seconds in this example) and a predetermined speed (800 rpm in this example) on one side (forward rotation side), and the other side (reverse rotation side). ) And a reverse drive for rotating the workpiece W at a predetermined speed (800 rpm in this example) for a predetermined time (5 seconds in this example). The wind speed of the sprayed air is set to about 30 m / sec.

  At this time, the distance between the air injection nozzle 31 and the workpiece W is adjusted to an optimum value (specifically, about 30 mm) by exchanging the distal end side pipe 39A. The spraying direction of the cleaning water is adjusted by swinging the air spray nozzle 31 </ b> A so as to be sprayed. By these adjustments and switching of the rotating direction of the rotary table 17, air is efficiently injected over the entire work W, and water and foreign matter on the surface are blown off.

  By these adjustments and switching of the rotation direction of the rotary table 17, air is efficiently injected over the entire workpiece W. In addition, a centrifugal force acts on the work W rotated at a higher speed than the first work, and the washing water and foreign matter adhering to the surface of the work W are efficiently removed by the action of the centrifugal force and the jet of air. Removed.

  If the workpiece W is positioned and placed on each of the pair of placement portions 19 and 19 arranged at symmetrical positions, the weight balance of the rotary table 17 becomes good, and the workpiece W is efficiently attached to the rotary shaft 21. It becomes possible to rotate around the axis.

  By improving the efficiency of the work in the first work and the second work as described above, tap water or the like is used as it is without using detergent or the like, and the temperature of the wash water is set to a low value of 40 degrees or less. Therefore, the cooling work after the work is almost unnecessary, and the working time is further shortened. In addition, the risk that the pre-purified water remains on the workpiece W during drying after the cleaning operation and cracks occur during assembly can be greatly reduced.

  Next, based on FIG. 11 thru | or FIG. 13, another part mentioned above is demonstrated about other embodiment of this invention.

By controlling the supply / discharge of the air to the air cylinder 44 through the air flow path 21a when supplying the air to the air cylinder 44 and discharging the air from the air cylinder 44, And a control unit (not shown) that controls expansion and contraction of the air cylinder 44. The operation of this control unit is controlled by the control panel 4.

  The air cylinder 44 is provided for each placement portion 19 and advances to the placement portion 19 by an extension operation and retreats from the placement portion 19 by a reduction operation.

When the air cylinder 44 advances to the mounting portion 19, the synthetic resin contact 44 a formed on the advance end side of the air cylinder 44 is positioned on the upper surface of the convex portion W <b> 1 protruding toward the center of the rotary table 17 of the workpiece W. Then, the vertical movement of the workpiece W is restricted. Since the movement to the four sides of the workpiece W by the positioning pins 22, Ru is restricted, the workpiece W is a mounting portion 19, is positioned and fixed.

  On the other hand, when the air cylinder 44 is retracted from the mounting portion 19, the contact 44 a of the air cylinder 44 is retracted from the upper surface of the convex portion W <b> 1 protruding toward the center of the rotary table 17 of the work W, and the work W is moved up and down. This allows the workpiece W to be removed from the placement unit 19. Further, a detection sensor 47 is provided for each mounting portion 19 so as to be parallel to the air cylinder 44, and the detection sensor 47 controls whether or not the workpiece W is mounted on the mounting portion 19. The board 4 can be determined.

The flow path 21a is formed at the axial center of the rotary shaft 22, and air is supplied to and discharged from each air cylinder 44 through the flow path 21a. Incidentally, an air hose for supplying and discharging air is connected to the lower end portion of the rotating shaft 21 via a rotary joint 48.

  According to the cleaning apparatus configured as described above, the workpiece W can be reliably positioned and fixed to the mounting portion 19 on the rotary table 17 by the positioning device 43. It is possible to reliably prevent W from being displaced unexpectedly.

  In addition, since a stepping motor is used as the drive motor 23, the rotational position of the rotary table 17 can be easily controlled. For example, the mounting unit 19 that desires to set the work W or the mounting unit 19 that wants to take out the work W works. It is also possible to perform control such that the rotary table 17 is rotationally driven so as to be closest to the user, and the operation is also performed by a single button operation of an operation button (not shown) installed on the operation panel 6. Etc. can be realized. Further, in order to clean the incompletely cleaned portion, it is easy to rotate the rotary table 17 to an arbitrary position.
