How To Choose A Positioner

Usually, when designing an electric-driven positioner solution, it is necessary to select the mechanical transmission method and corresponding transmission mechanism from the motor to the workbench. Before selecting, the following requirements must be clarified according to the characteristics of the assembly and welding process:
(1) Functional requirements for the positioner: refers to what actions the positioner should be able to achieve, such as translation, lifting or rotation. If it is translation, is it linear translation or curved translation; if it is rotation, is it continuous rotation or intermittent flipping, etc.;
(2) Requirements for movement speed: It must be clear whether it is fast or slow, constant speed or variable speed, and whether it is stepped or stepless;
(3) Requirements for transmission stability and accuracy: For positioners used for automatic welding, the transmission requires high accuracy, so worm gear transmission and gear transmission can be selected;
(4) Requirements for self-locking, overload protection, vibration absorption and other capabilities: For general lifting or flipping and transmission with the risk of overturning, the transmission mechanism must have self-locking capabilities for safety. There may be multiple transmission modes and their corresponding transmission mechanisms. At this time, it is necessary to comprehensively consider their transmission power, compactness, transmission efficiency and manufacturing cost and then select the best one.
