DC motor motor automatic carbon brush cover assembly machine how to carry out maintenance?
First, mechanical parts maintenance
1, transmission components
Belt and chain: Check the tension of the belt regularly, generally once every [X] weeks. If the belt is too loose, it will lead to lower power transmission efficiency or even slip; too tight will increase the motor load and belt wear. For the chain, pay attention to lubrication, add special chain lubricant every [X] months, and check the chain links for looseness, wear or breakage.
Gears: Check the wear of the gears every [X] months, mainly observing whether there are wear marks on the teeth, missing teeth and other problems. If the gears are found to be badly worn, they should be replaced in time so as not to affect the transmission accuracy and stability. At the same time, to ensure that there is enough lubricant in the gear box, generally every [X] years to replace the gear box lubricant.
2, bearing
Bearings are the key to ensure the normal operation of the rotating parts of the machine. Regularly (every [X] months) check the lubrication of the bearings, add the appropriate amount of grease. At the same time, check the bearings for abnormal noise and vibration; if so, it may be a sign that the bearings are worn or damaged and need to be replaced in time.
3、Fixture and robot arm
Fixture: Check whether the clamping force of the fixture is appropriate and the positioning accuracy of the fixture before each use. Periodically (every [X] weeks) clean the oil and impurities on the fixture surface to avoid affecting the clamping effect. For fixtures with severe wear, replace or repair them in time to ensure that the carbon brushes and cover plates can be accurately fixed.
Mechanical arm: Check the movement of the mechanical arm every day to see if it is flexible and there is no jamming phenomenon. Regularly clean the joints and guide rails of the robotic arm to remove dust and debris, and add appropriate amount of lubricant. Calibrate the precision of the robotic arm once every [X] years to ensure that it can accurately grasp and place parts.
4. Machine Structure
Regularly (every [X] months) check the connecting bolts of the body structure for looseness, especially after the machine has been running for a while, as vibration may cause the bolts to loosen. Check whether there is any deformation of the fuselage. If the fuselage is found to be deformed, analyze the cause and repair it in time, so as not to affect the overall stability and precision of the assembling machine.
Second, the electrical system maintenance
1、Motor
Regularly (every [X] months) clean the dust and debris on the motor surface to ensure good heat dissipation. Check whether the wiring of the motor is firm and there are no signs of looseness or burning. Also, measure the insulation resistance of the motor, usually once every [X] years, to ensure good insulation. For DC motors, also pay attention to check the wear and tear of the brushes, when the brushes are worn to a certain extent, they should be replaced in time.
2、Sensors
Photoelectric sensor: Clean the lens and optical path of the sensor regularly to avoid dust, oil, etc. blocking the optical path and affecting the detection effect. Every [X] month to check whether the installation position of the sensor is offset, if necessary, timely adjustment. At the same time, check whether the output signal of the sensor is normal or not, you can use an oscilloscope or multimeter to test.
Proximity sensors, pressure sensors, etc.: Check the sensing surfaces of the sensors for damage or dirt and clean them regularly (every [X] months). For pressure sensors, also check for leaks in the connecting piping. Regular calibration of the sensor to ensure that its detection accuracy meets the requirements, calibration cycle according to the frequency of use and importance of the sensor, generally every [X] quarter.
3、Controller and line
Programmable Logic Controller (PLC): Keep the working environment of PLC dry and clean, avoid dust and moisture entry. Backup the program and parameter settings of the PLC regularly (every [X] years) to prevent data loss. Check whether the input/output (I/O) interface of the PLC is normal, and replace the I/O module if it is faulty.
Wiring: Check the electrical wiring for damage, deterioration, short circuits, or broken circuits, especially in the vicinity of mechanical moving parts that are susceptible to wear and tear. Regularly (every [X] months) organize the lines to avoid hidden dangers and signal interference caused by messy lines.
Third, software system maintenance
Regularly (every [X] months) back up the data and programs of the software system, including the control program, parameter settings and so on. At the same time, pay attention to the update information released by the software developer and update the software in time to repair software vulnerabilities, improve system performance and compatibility. Before updating the software, back up the existing data and test the update in the test environment to ensure that the software update will not adversely affect production.
Fourth, the working environment maintenance
Keep the working environment of the assembly machine clean and dry, temperature and humidity should be controlled within the appropriate range (temperature is generally [X]℃ - [X]℃, humidity in [X]% - [X]%). Avoid exposing the machine to direct sunlight, rain or near heat sources. If the working environment is dusty, install air filtration equipment to reduce the effect of dust on the machine. At the same time, to avoid electromagnetic interference, keep the assembling machine away from strong electromagnetic interference sources such as large motors and transformers, or take effective electromagnetic shielding measures.
