In the repair of circuit boards of industrial KUKA welding robots, it is necessary to be familiar with the damage characteristics of commonly used components and component detection methods
1. The resistor with small resistance value and the resistor with high power in the circuit board are easy to be damaged
The resistor with a small resistance value in the circuit board is often used to limit the current on the power supply line, that is, to act as a fuse, and if the current is too large, it will first blow it off. In addition, many ground capacitors are used on the power supply line to filter, and the size and capacity are generally large, and if the voltage or current is unstable, the capacitor will break down and cause leakage.
2. Fault characteristics and repair of capacitor damage in KUKA robot circuit board
Faults caused by capacitor damage in circuit boards are common in electronic industrial robots, especially electrolytic capacitor damage***. Capacitor damage is manifested as: 1. Capacity decreases, 2. Capacity is completely lost, 3. Current leakage, 4. Short circuit.
3. Determine the quality of the operational amplifier in the circuit board
Understand the above points, so that you can judge the quality of the op amp without using the substitution method or removing the chip on the circuit board.

Manual operation of industrial robots – KUKA robots
The linear motion of an industrial robot refers to the linear motion of the tool TCP mounted on the flange of the sixth axis of the robot in space. The coordinate linear motion should specify the coordinate system, tool coordinates, and workpiece coordinates. Coordinate systems include earth coordinates, datum coordinates, tool coordinates, and workpiece coordinates. Specified ...

Precautions for disassembling the A6-axis motor of KUKA robots
1. When replacing the motor, pay attention to handling with care to avoid damaging the motor.
2. When the motor is withdrawn from the reducer or installed into the reducer, attention should be paid to the horizontal movement to avoid the splash wear of the motor and the reducer.
3. The direction of the power cord plug of the motor of the new device may be the same as the original plug ...

Obstacle avoidance control of the manipulator – KUKA robots
The kinematic redundancy of freedom of the manipulator means that the manipulator has more degrees of freedom than is required at the end of the manipulator. Kinematic manipulators with redundant degrees of freedom have better functions than manipulators with non-redundant degrees of freedom. For example, a manipulator with non-redundant degrees of freedom has obstacles in the external environment.
