In order to enable the welding robot to work efficiently and ensure its normal operation, users need to regularly maintain and inspect the robot body and system after using the robot for a predetermined period of time, while also ensuring the safety of equipment and personnel during operation. The robot should undergo a spot check every 4000 hours (or more than two years) of operation. It is recommended that users hire welding robot professionals for inspection.

1、 Inspection of the main body of the welding robot

1. The robot body and control box are equipped with lithium batteries for servo motor encoder data backup. The service life of the battery varies with the working environment. When it exceeds two years, the battery needs to be replaced, otherwise the motor encoder data will be lost and the origin adjustment needs to be carried out again. Before replacement, it is necessary to backup the teaching data to prevent the loss of teaching programs and set parameters.

2. Are the axis marks at the origin aligned.

3. Check whether the operation of each axis is smooth and stable during automatic and manual operation.

4. Whether the robot safety switch and emergency stop switch are normal.

5. Whether the wire feeding mechanism is stable.

6. Whether the deceleration mechanism is worn.

7. Adjust the elasticity of the toothed belt.

8. Add lubricating oil to the TW, BW, and RW axles (ordinary butter is not allowed to be added to the oil holes).

2、 Control box inspection

1. Lithium battery replacement.

2. Check the cooling fan.

3. Cable inspection (grounding cable, power cable, control cable).

4. Are the switches on the control panel of the teaching pendant functioning properly.

5. Dust removal inside the control box.

3、 External axis and positioning fixture inspection

1. Lithium battery replacement.

2. Add lubricating oil.

3. Whether the connecting bolts are tightened.

4. Are there any abnormalities during runtime.

5. Check if the locating pin is worn.

4、 Welding machine section

1. Welding power supply (internal dust removal, whether the connection parts are loose).

2. Welding gun (nozzle cleaning, whether the wire feeding tube is blocked, whether the insulation is normal, whether the gas pipe is leaking, whether the cable is loose or damaged).

3. Wire feeding device (whether the wire feeding wheel is worn, whether the SUS tube is damaged or worn, and whether the wire feeding motor is abnormal).

4. Grounding cable (whether there is burn damage, cracking, and whether the connection is tight).
