1. Power supply in front of the device
The high rate of defects in the power supply during the programming of the KUKA robot is the entire faulty device, so it is easy to overhaul the power supply first
Multiplier.
2. First the general and then the special
Faults caused by the quality of assemblies or other equipment faults generally account for about 50% of common faults
Right. Most of the special faults of electrical equipment are soft faults, which need to be measured and repaired through experience and instruments. For example, there is
Since the 0.5 kW motor cannot move the load, some people think that it is a load problem. Based on our experience, we should prioritize
Wearing thick gloves and grabbing along the direction of rotation of the motor, the result was caught, which is the problem of the motor itself.
3. First outside and then inside
Do not rush to replace damaged electrical components, consider replacing them after acknowledging that the peripheral equipment circuit is normal
The electrical components of the KUKA robotic arm are damaged.
4. DC first and then communication
When overhauling, it is necessary to check the static working point of the DC circuit first, and then check the dynamic working point of the communication loop.
5. Debugging after defeat.
For the electrical equipment that coexists with debugging and faults, the faults should be removed first, and then the debugging should be carried out under the premise that the circuit is normal.
KUKA robots
6. Move your mouth before you start
Regarding faulty electrical equipment, we should not rush to start, but should first inquire about the cause and cause of the fault
There are no obstacles. For unfamiliar equipment, you should be familiar with the circuit principle and structural characteristics, and abide by the corresponding rules. take apart
Before unloading, you should be fully familiar with the function, location, connection method and relationship with other surrounding equipment KUKA robotic arms
If there are no assembly drawings, sketches and symbols should be made when disassembled.
7. First outside and then inside
See if the device has significant cracks and defects, learn about its repair history and lifespan, and then look at the device
Look inside the machine. Before dismantling, sweep away the surrounding faulty elements, and then disassemble after admitting that it is an internal fault, no
If you blindly disassemble the device, the situation will get worse and worse.
8. Mechanical first and then electrical
As long as it is admitted that there is no fault with the mechanical parts, the electrical inspection is carried out. When looking at circuit faults,
It is necessary to use a detector to find out the faulty part, and then check the circuit after admitting that there is no contact defect
Relationship with mechanical operation to avoid misjudgment of KUKA robot programming.
9. Static first and then dynamic
When the equipment is not powered on, judge whether the buttons, contactors, thermal relays and fuses of the electrical equipment are in good condition
Then confirm the problem. Power on test, listen to the sound, measure the parameters, identify the fault, and carry out repairs.
For example, when the motor is out of phase, if the measured three-phase voltage cannot be distinguished, the sound of the KUKA robotic arm should be listened to, and each phase should be measured separately
As long as a voltage is applied to the ground, it is possible to determine which phase is defective.
10. Clean before repair
For the electrical equipment with severe pollution, the buttons, wiring points, and contact points should be cleaned first, and the external environment control keys should be checked to see if they are out of order. Many of the problems are caused by dust and conductive dust. Once cleaned, the problem is often wiped out.

Cartesian coordinates are different from articulated robots
1. Working space and carrying capacity:
1. The standard length of a single root of Cartesian coordinate type is 6m, and it can reach 100m after assembly; Combined into a gantry robot, its working space can be a very three-dimensional space. A single root can carry 10-200 kg, and the special structure can reach 2400 kg.
