How Can You Extend the Lifespan of a Welding Robot?
2019-07-26
I. Inspection and Maintenance of Welding Robots
1. Wire feeding mechanism. Check whether the wire feeding force is normal, whether the wire feed tube is damaged, and whether there are any abnormal alarms.
2. Is the gas flow normal?
3. Is the torch safety protection system functioning properly? (Do not disable the torch safety protection system.)
4. Is the water circulation system operating normally?
5. Test the TCP (it is recommended to prepare a test program and run it after each shift).
II. Weekly Inspection and Maintenance of Welding Robots
1. Wipe down the robot’s axes.
2. Check the accuracy of the TCP.
3. Check the oil level in the residue tank.
4. Check whether the zero positions of each robot axis are accurate.
5. Clean the filter behind the welding machine’s oil tank.
6. Clean the filter at the compressed air inlet.
7. Remove debris from the cutting torch nozzle to prevent clogging of the water circulation system.
8. Clean the wire feeding mechanism, including the feed rollers, pressure rollers, and wire guide tube.
9. Inspect the hose bundle and wire feed hose for damage or tears. (It is recommended to remove the entire hose bundle and clean it with compressed air.)
10. Check that the cutting torch safety system is functioning properly and that the external emergency stop button is operational.
III. Monthly Inspection and Maintenance of Welding Robots
1. Lubricate the robot’s axes. Axes 1 through 6 are white and require lubricating oil. Oil part number: 86E006.
2. Lubricate the RP positioner on the RTS guide rail and the red grease fittings with grease. Grease part number: 86K007
3. Apply blue grease and gray conductive grease to the RP positioner. Grease code: 86K004
4. Lubricate the wire feed needle roller bearings with lubricating oil. (A small amount of grease may be used)
5. Clean the spray gun assembly and refill it with air motor lubricant. (Regular oil is acceptable)
6. Clean the control cabinet and welding machine with compressed air.
7. Check the cooling water level in the welding machine’s tank and top up the coolant as needed (distilled water with a small amount of industrial alcohol).
8. In addition to tasks 1–7, complete all items on the weekly inspection che
