Don't panic when the robot has a problem in the working process, if the fault is not caused by the controller, then the cause of the problem must be the damage to the machine parts. In order to deal with the problem in the easiest way possible, the problem should be analyzed. And the need to find out which part is causing the problem. What are the methods for diagnosing and protecting industrial robots?
Ask before you act
When it comes to faulty electrical equipment, don't rush to get started, but first ask about the process and the phenomenon before and after the fault. For equipment that you don't understand, it is first necessary to understand the circuit principle and structural characteristics, and comply with the corresponding rules. Before dismantling, you should fully understand the function, location, connection method and connection method of each electrical component and its connection with other surrounding equipment. If there are no assembly drawings, sketches are drawn and symbolized during the disassembly process.
Outside first, then inside
Look at the exterior first, see if the device has significant cracks and defects, understand its protection history and service life, and then look inside the machine. Before dismantling, it is necessary to eliminate the surrounding faulty elements, and only after determining the internal faults can it be disassembled. Otherwise, blindly taking it apart will make the device worse and worse.
Mechanical before electrical
An electrical inspection should only be carried out after acknowledging that there is no fault with the mechanical parts. When looking for faults in a circuit, use the detector to find the faulty area. After admitting that there is no contact defect, check the connection between the line and the operation of the machine to avoid judgment errors.
Clean before you repair
For highly contaminated electrical equipment, the first thing to do is to clean buttons, junctions and contacts, and to see if external control keys are not working. Many of the problems are caused by conductive dirt and dust. After cleaning, the problem is usually eliminated.
DC first, then communication
When overhauling, it is necessary to check the static working point of the DC loop first, and then check the dynamic working point of the communication loop.

Robot maintenance content - KUKA robots
The maintenance content of the robot is mainly to replace the lubricating oil of the six shaft reducers and the lubricating oil of the J4 shaft gear shaft, the replacement of wearing parts, the inspection of the operation status of each module in the control cabinet, and the inspection of the wear status of each cable in the control cabinet.
If the grease is not replaced for a long time, the six axes of the robot will be formed.
