Methods for Operation Efficiency Optimization of Industrial Robots
A.1 Optimization of Process Scheme
Process scheme affects the nominal energy consumption in operation, which in turn, affects the
operation efficiency of the industrial robots. When the nominal energy consumption in
operation is relatively large, in accordance with the actual situation, the following optimization
methods should be adopted, or a combination and integration of the following methods should
be adopted:
a) Optimization of operation trajectory: optimize the operation trajectory of the
industrial robot; reasonably plan its motion path and operation speed. Select an
appropriate space motion curve; avoid excessively frequent acceleration and
deceleration; enhance the smoothness of the trajectory; reduce the nominal energy
consumption in operation of the industrial robot; improve the operation efficiency.
b) Optimization of matching attribute: when the industrial robot is at the rated load, it
can not only thoroughly satisfy the performance requirements, but also, the utilization
rate of the motor capacity is extremely high. Under this circumstance, the energy
utilization rate of the industrial robot is relatively high, and the application of large-
load robots in light-weight occasions shall be avoided.
c) Optimization of process parameters: process parameters affect the load of the
industrial robot, and further affect the energy consumption in operation of the
industrial robot. Through the optimization of process parameters, improve the
operation efficiency of the industrial robot.
A.2 Optimization of Working Conditions and Quality
The operating conditions and processing quality of industrial robots will affect the energy
efficiency ratio in operation, which in turn, affects the operation efficiency of the industrial
robots. When the energy efficiency ratio in operation is relatively small, in accordance with the
actual situation, the following optimization methods should be adopted, or a combination and
integration of the following methods should be adopted:
a) Optimization of assistant time: when the assistant energy consumption ratio in
operation is relatively large, shorten the assistant time of links like clamping and
detection during the operation of the industrial robot; reduce the assistant energy
consumption and realize the improvement of the energy efficiency in operation;
b) Optimization of reliability: when the fault status energy consumption ratio in
operation is relatively large, it is advisable to reduce the failure rate of the industrial
