About Industry Robot，You Must know this four point....

Industrial robot management and maintenance is an emerging technology field for enterprises. It requires not only a mastery of the basic principles of industrial robot technology but also skills in robot installation, commissioning, system programming, and repair. Therefore, maintenance personnel must continuously improve their comprehensive competence and skills to meet the demands of industrial robot maintenance.

1. Daily Robot Inspection

1.1 Brake Inspection: Before normal operation, maintenance personnel must inspect the motor brakes on each axis. This inspection is performed as follows: First, operate each robot axis to its maximum load position. Second, turn the motor mode selector switch on the robot controller to "MOTORS OFF." Third, verify that each axis remains in its initial position. If the robot remains in position after turning off the motors, the brakes are functioning properly.

1.2 Risk of Loss of Deceleration (250 mm/s) Functionality: Do not change the gear ratio or other motion parameters from a computer or teach pendant, as this will affect the deceleration (250 mm/s) function.

1.3 Safe Use of the Teach Pendant: When the enable button on the teach pendant is halfway pressed, the system switches to motor-on mode. When the button is released or fully pressed, the system switches to motor-off mode. To safely use the teach pendant, the following guidelines must be followed: First, the enable button must be immediately released during programming or debugging, and whenever the robot does not need to move. Second, after entering the safe area, the programmer must carry the teach pendant with them to prevent others from moving the robot.

1.4 Working within the robot's operating range: If working within the robot's operating range is unavoidable, the following points must be observed: First, the mode selector switch on the controller must be in the manual position to disconnect the enable device from the computer or remote control. Second, when the mode selector switch is in the <250 mm/s position, the maximum speed is limited to 250 mm/s. The switch is typically rotated to this position when entering the work area. Only those who are very familiar with the robot should use full speed (100% full speed > 3000 rpm). Third, pay attention to the rotation axes of each industrial robot arm, being careful not to get hair or clothing entangled in them. Also pay attention to other selected components or other equipment on the robot. Fourth, check the motor brakes on each axis. 

2. The maintenance frequency for industrial robots is as follows:

1. General maintenance, once a day;

2. Clean/replace filter cloth, once every 500 hours;

3. Replace measurement system batteries, twice every 7,000 hours;

4. Replace computer fan unit and servo fan unit, once every 50,000 hours;

5. Check cooler, once a month.

Notes: This process requires the following:

1. The interval depends primarily on environmental conditions;

2. The maintenance frequency depends on the robot's operating time and temperature; and finally, verify that the robot is operating smoothly.

3. Robot Maintenance:

1. General maintenance, once a day;

2. Axis brake test, once a day;

3. Lubricate the pinion and gear three times, once every 1,000 hours;

4. Lubricate the hollow wrist, once every 500 hours;

5. The lubricating oil in each gearbox should be replaced annually for the first time and every five years thereafter. It should also be noted that the interval depends primarily on environmental conditions and the robot's operating time and temperature; and finally, verify that the robot is operating smoothly. 

4. General Maintenance of Industrial Robots

4.1 Cleaning the Robot Arm: Clean the robot base and arm regularly. Exercise caution when using solvents. Avoid strong solvents such as acetone. High-pressure cleaning equipment may be used, but avoid spraying directly onto the robot arm. If the robot arm is protected by a film of grease or other protective material, remove it as needed. To prevent static electricity, wipe non-conductive surfaces such as spray equipment and hoses with a damp or damp cloth. Do not use a dry cloth.

4.2 Hollow Wrist: Clean the hollow wrist regularly as necessary to prevent the accumulation of dust and particles. Use a lint-free cloth for cleaning. After cleaning the wrist, apply a small amount of petroleum jelly or a similar substance to the wrist surface to make subsequent cleaning easier.

4.3 Regular Inspection: Check the following points as needed: Check for oil leaks. If significant oil leaks are detected, seek maintenance assistance. Check for excessive gear backlash. If excessive backlash is detected, seek maintenance assistance. Check for damage to the cables between the control cabinet, purge unit, process cabinet, and robot arm.

4.4 Checking the Foundation and Securing
