Some industrial robots have great power, if not properly operated, will cause serious impact on personnel or equipment, and may even cause death, so in the maintenance must be very careful, must strictly follow the maintenance manual, after all, the safety of personnel and equipment is the first yi.

Industrial robot brand is numerous, model group, application environment is different, here just cite a few general considerations.

1, pay attention to check whether there is water, oil into the electrical control box, if the electrical damp, do not start.

2. Check whether the supply voltage is normal, whether the front and rear safety door switches are normal, verify whether the motor turns in the same direction, and then turn on the power.

3. Turn off the injection mechanical source when the industrial robot needs to be dismantled; Turn off the power of the manipulator; Turn off the pressure source of the manipulator; Remove the air pressure and loosen the screw on the cylinder fixing plate.

4. Move the buffer seat close to the arm, tighten and pull the cylinder fixing plate, so that the arm cannot move. Lock the rotating safety screw so that the manipulator cannot rotate.

Maintenance process

In order to extend the life of the equipment and reduce the failure rate, regular maintenance is essential, which is also a link for the safe use of industrial robots.

1) maintenance cycle

1. Daily robot maintenance

A. check the appearance of the equipment for dust attachment.

B. Wear and pressure loss of external cables, whether the joints are fixed and loose, and whether the cooling fan works normally.

C. Whether the operation buttons work normally and whether the robot works normally.

2. Three months maintenance (including daily maintenance)

A. Whether the terminals are fixed well.

B. Whether the base of the robot body is fixed well and there is no dust inside.

3. Annual maintenance (including daily \ 3 months maintenance)

A. Check whether the joints of each base plate inside the control box are loose.

B. Whether there are any abnormal conditions in the internal lines (such as whether there are broken lines, whether there is no dust, and whether there are contact points).

C. Check whether the wiring in the body is broken.

D. Whether the battery voltage of the robot is normal (normally 3.6v).

E. Whether the brakes of robot motors of each shaft are normal or not.

F. Is the belt light tightness of axis 5 normal?

G. Whether the voltage of the special oil for the refueling robot of 4\5\6 shaft reducer is normal or not.

4. Three years maintenance (including daily \ three months and one year maintenance).

A. Replace oil for 1\2\3 shaft reducer (special oil for robot).

B. Replacement of robot battery (special battery for robot).

Routine maintenance, three-month maintenance and spot inspection shall be conducted by users.

Annual maintenance and spot inspection shall be inspected, adjusted, maintained or replaced by agents or professionals.

2) maintenance spare parts

1. Roller grease.

2. Maintenance spare parts package: SMB battery, cooling fan, dustproof filter, contactor contact, motor upper lamp, fuse.

3) ontology standard maintenance details

1. Routine examination:

A. clean the robot body. Dust and clean the robot body according to the field work.

B. Check whether the ontology and 6-axis tool end are fixed properly.

C. Check the limit block of each shaft.

D. Check the cable status and wear condition of robot signal cable, power cable, user cable and body cable.

E. Check the sealing state, check whether there is oil leakage or oil leakage in the gear box and wrist, etc.

2. Functional measurement:

A. Temperature check. Professional infrared temperature qiang confirms whether the temperature of the motor is normal during operation.

B. Noise inspection: check whether there is any abnormality in the motor or reducer under the manual operation state through the noise detector, so as to take it as a standard to check the state of components.

C. Check the repeat accuracy, and confirm whether the repeat accuracy of the robot is normal by using a percentage meter.

D. Measure the mechanical zero position to check whether the robot's current zero position is consistent with the standard calibration wei.

E. Check the state of motor brake, test the voltage value of motor brake on, and test the motor brake function of each shaft.

3. Replacement of maintenance parts:

A. replacement of body oil, replacement of robot gear box, balance cylinder or connecting rod oil.

B. robot SMB board inspection and battery replacement. Check whether the fixed connection of SMB board is normal and replace the battery.

4) standard maintenance details of control cabinet

1. Routine examination:

A. clean the control cabinet, clean the appearance of the robot control cabinet, and dust the inside of the control cabinet.

B. Check the fastness of all parts of the control cabinet, and check the fastening state of all parts in the control cabinet.

C. Clean the teaching instrument, the teaching instrument and the cable.

D. Circuit board indicator status, check the status lights of each circuit board in the control cabinet, and confirm the status of the circuit board.

E. Check the cables inside the control cabinet. All cable plugs in the control cabinet are connected firmly and the cables are clean and tidy.

2. Control cabinet measurement:

A. Power supply voltage measurement, measuring the robot's incoming voltage, driving voltage and power module voltage, and sampling the waveform of each voltage through the oscilloscope, so as to conduct the overall analysis of the voltage.

B. Test the safety circuit to check whether the operation state of the safety circuit (AS, GS, ES) is normal.

C. Function test of the instructor, check the validity of all keys, check whether the emergency stop circuit is normal, and test the functions of the touch screen and the display screen.

D. Check the calibration compensation value of the system to check whether the calibration compensation value parameters of the robot are consistent with the factory configuration value.

E. System backup and import detection to check whether the robot can normally complete program backup and reimport functions.

F. Check the hard disk space, optimize the hard disk space of the robot control cabinet, and ensure the normal operation space.

G. Check the humidity. Ensure the normal operation of the robot within the permitted use by checking the humidity of the control cabinet and the environment.

3. Replacement of maintenance parts:

A. replace the drive fan unit and the drive unit cooling fan.

B. Replace the dustproof filter and control cabinet dustproof filter.

C. Auxiliary contactor contact replacement, control cabinet auxiliary contactor normally open and normally closed contact replacement.

D. Fuse replacement, fuse replacement of control cabinet.

E. Change the motor power indicator light, and change the indicator light inside the motor power button on the control cabinet operation panel.
