Description

The present invention relates to a washing machine management device for managing an NC washing machine and a washing machine management method.

In a cleaning step of cleaning a work in a work processing process or the like, an NC cleaning machine is used in which a nozzle or the like for injecting a cleaning liquid is controlled by using NC control (numerical control). In order to perform proper cleaning, it is necessary to manage the NC washing machine. At present, the discharge pressure of the cleaning liquid and the aim inspection are carried out as the factor system management items of the NC cleaning machine.

As the discharge pressure of the cleaning liquid, the original pressure of the high-pressure pump that pumps the cleaning liquid to the cleaning nozzle is confirmed, and whether or not this original pressure is normal is routinely controlled.
As an aim inspection, after coloring the work with a color spray, the NC washer is operated to inject a cleaning liquid from the cleaning nozzle to clean the work, and the cleaning result (remaining condition of the colored paint) is used as a limit sample. By comparison, make sure that the capacity of the washer (positional accuracy, pressure, flow rate) has not decreased.

Further, Patent Document 1 describes the cleaning liquid discharged from the nozzle in a cleaning device that discharges the cleaning liquid from the nozzle to the substrate while holding the substrate such as a semiconductor wafer in a horizontal posture and rotating it around a vertical axis. A technique for controlling the discharge flow rate and discharge pressure of a cleaning liquid from a nozzle by measuring the flow rate and pressure is disclosed.

Japanese Patent No. 3095324

However, there are the following problems in the discharge pressure and aim inspection of the cleaning liquid currently performed as a factor system control item of the NC washer.
That is, the discharge pressure is generally controlled by the main pressure of the high-pressure pump, but the pressure applied to the actual cleaning parts is not known by the main pressure management. Further, depending on the washing machine used, even if the capacity of the high-pressure pump is the same, the specifications such as the hole diameter and the number of holes differ depending on the washing nozzle used, so that detailed management is difficult.

Further, in the nozzle aim inspection, the NC cleaning machine is actually operated according to the work to perform the cleaning inspection, so that the cleaning state can be inspected corresponding to various operations of the nozzle. However, if a color spray is used, cleaning is performed. It is necessary to compare all nozzle contact inspections using limit samples, making it difficult to detect abnormalities such as deterioration of the washing machine, and there are variations in the judgment workers. In addition, since the paint that colors the work is scattered and adheres to the inside of the machine, it is necessary to take measures against this.

In the technique of Patent Document 1, it is unknown whether the washing machine is an NC washing machine, but since the flow rate and pressure of the washing liquid discharged from the nozzle are measured, the pressure applied to the work can be grasped. However, it is merely stated that the pressure of the cleaning liquid discharged from the nozzle is measured using a strain gauge, which is not sufficient to properly evaluate the performance of the nozzle. Further, unlike the above-mentioned aim inspection, the inspection is not performed according to the NC control, so it is considered difficult to inspect the cleaning state corresponding to various operations of the nozzle.

Axis diagnostic position) P5, A-axis diagnostic point (A-axis rotation position) P6, C-axis diagnostic point (C-axis rotation position) P7, when it is evaluated that the injection characteristics of the cleaning nozzle 12 are not normal. Is.

In order to evaluate that the injection characteristics of the cleaning nozzle 12 are normal at the diagnostic point P1, the performance of the injection system is normal and the cleaning nozzle 12 is in any of the X-axis direction, the Y-axis direction, and the Z-axis direction. It is necessary to move appropriately to the movable limit (maximum movement distance) in the direction, and to rotate the fixing base 13 appropriately to the movable limit (maximum rotation angle) in either direction around the A axis or the B axis. Is. Therefore, when the injection characteristics of the cleaning nozzle 12 are normal at the comprehensive diagnosis position P1, the injection characteristics of the cleaning nozzle 12 are also normal at the other positions P2 to P7 as in pattern 1. Therefore, if it is evaluated that the injection characteristics of the cleaning nozzle 12 are normal at the diagnostic point P1, it can be determined that the performances of the injection system, the nozzle moving mechanism 20, and the rotation drive mechanism 30 are all normal.

On the other hand, when it is evaluated that the injection characteristics of the cleaning nozzle 12 are not normal at the diagnosis point P1, it is because the performance of any one or more of the injection system, the nozzle moving mechanism 20 and the rotation drive mechanism 30 is not normal. In this case, by evaluating the injection characteristics of the cleaning nozzle 12 at the origin P2, it is possible to narrow down whether the injection system is abnormal or the nozzle moving mechanism 20 or the rotation drive mechanism 30 is abnormal.

That is, if the injection characteristics of the cleaning nozzle 12 at the origin P2 are normal, it can be narrowed down that either the nozzle moving mechanism 20 or the rotation driving mechanism 30 is abnormal. Further, if the injection characteristics of the cleaning nozzle 12 at the origin P2 are not normal, it can be inferred that there is an abnormality in the injection system or there is an abnormality in the movement to the origin P2.

If there is an abnormality in the injection system, it will be evaluated that the injection characteristics of the cleaning nozzles 12 are not normal at positions P1 to P7 (Pattern 8), but conversely, the cleaning nozzles 12 at positions P1 to P7. It is not possible to identify that there is an abnormality in the injection system just because the injection characteristics of the above are evaluated as abnormal. That is, even if there is a complex abnormality in the system such as movement to each position P1 to P7, the pattern 8 is obtained. Therefore, in the case of pattern 8, it is necessary to carry out a separate inspection in order to identify which one has an abnormality.

If the injection characteristics of the cleaning nozzle 12 at the diagnosis point P1 are not normal, but the injection characteristics of the cleaning nozzle 12 at the origin P2 are normal, it is narrowed down that either the nozzle moving mechanism 20 or the rotation drive mechanism 30 is abnormal. Therefore, if the injection characteristics of the cleaning nozzle 12 are evaluated at the respective positions P3 to P7, it is possible to identify which of the corresponding mobile systems 21 to 23 and the rotating systems 31 and 32 has an abnormality.

That is, if there is an abnormality in the performance of the X-direction moving system 21, it is evaluated that the injection characteristics of the cleaning nozzle 12 are not normal at the X-axis diagnostic point P3 (Pattern 3). If there is an abnormality in the performance of the Y-direction moving system 22, it is evaluated that the injection characteristics of the cleaning nozzle 12 are not normal at the Y-axis diagnostic point P4 (Pattern 4). If there is an abnormality in the performance of the Z-direction moving system 23, it is evaluated that the injection characteristics of the cleaning nozzle 12 are not normal at the Z-axis diagnostic point P5 (Pattern 5). Further, if there is an abnormality in the performance of the rotation system 31 around the A-axis, it is evaluated that the injection characteristics of the cleaning nozzle 12 are not normal at the A-axis diagnostic point P6 (Pattern 6). If there is an abnormality in the performance of the rotation system 32 around the C-axis, it is evaluated that the injection characteristics of the cleaning nozzle 12 are not normal at the C-axis diagnostic point P7 (pattern 7).
