Inspection and repair of image measuring instrument manufacturer

Instruments and meters are applicable to various production enterprises and widely used in electronic production enterprises. Many electronic products are tested by instruments before leaving the factory. Instruments such as image measuring instruments detect electronic components. Instrument testing can reduce the opportunities for waste and defective products and improve the quality of enterprise products. However, the detection of instruments and meters is also very important. Taking the electronic company as an example, the semi-automatic image Measuring Instrument introduces several commonly used instrument maintenance methods:

1.Observation method

The first common method is to observe the instrument and use vision, smell, touch, hearing, etc. to observe whether the instrument has burnt smell, spots and noise. Usually, burnt utensils will have an unpleasant smell, which is easy to smell. If the chip is short circuited, it will feel hot. You can see the broken place with your eyes. Sometimes you can hear abnormal noise from the machine. These may be problems with the instrument.
2. Restart method
If the instrument has poor contact or temporary failure, you can turn off the instrument, plug in the power switch again, or tap the faulty part of the instrument and restart it. After restart, check whether the instrument can operate normally. If possible, it means the instrument has poor contact or the power supply has poor contact.
3. Temperature regulation method
Due to seasonal reasons, the temperature is sometimes too high or too low, which may affect the instrument. If the instrument is shut down after a failure, it will restart after a period of time and fail after a period of normal operation. Repeatedly, this phenomenon may be caused by a part of the instrument that cannot be used normally due to temperature rise during operation. It can be cooled with absolute ethanol. For low temperature, indoor working environment temperature can be adjusted.
4. Troubleshooting Inspection and repair of image measuring instrument manufacturer
The elimination method is that when the instrument fails, some internal boards or equipment of the automatic image measuring instrument can be unplugged. If the instrument returns to normal after unplugging the device, it indicates that the unplugged part has a problem and needs to be replaced.
5. Replacement method
If you know the equipment that has failed, or you are not sure whether there is a problem with the parts, you can check whether the fault has been eliminated by replacing the same new equipment.
6. Comparison method
If you have the necessary equipment, such as multimeter, oscilloscope and two instruments of the same type, you can perform some comparative tests. Such as waveform comparison, voltage comparison, current comparison, output comparison, etc. Run the normal instrument and the instrument under test under the same conditions, and then measure and compare the data. If there are differences in some places, the problem is likely to occur here.
7. Fault flow diagram method
According to the fault flow chart, narrow fault scope shall be eliminated one by one. It is not necessary to use the same type of instrument to compare the same condition detection for gantry type image measuring instrument. The signal can be checked through signal comparison and component exchange, which is more convenient and faster than the comparison method.
