Single-axis robots, also called single-axis linear modules, electric sliding tables, etc., which is one kind of mechanical structure that can provide linear motion, and can complete more complex tasks through combination. The completion of the specified work also shows that the single-axis robot has developed very mature.
The biggest feature of a single-axis robot is high precision, and high precision is achieved by the linear guides and ball screws in the physical internal structure of the single-axis robot. High-precision motion is usually determined by the motion reference data of the mechanical motion. In a single-axis robot with stable performance, its motion reference can be composed of guide rail elements. When sensors are used to measure and compensate and correct the motion error, the mechanical system of the single-axis robot, such as a steel ruler, will become the data log of the measurement object. Therefore, manufacturers will use the high degree of shape accuracy as the benchmark for single-axis robots in order to improve their motion accuracy.
The single-axis robot has a simple structure. The profile is the main body, the built-in guide screw and other transmission accessories are combined together. The linear structure determines that it can only complete simple point-to-point motion; no complex components, no long-term maintenance, usually only need lubricate on time; usually we can see that the speed of multi-axis robots is not too fast, but there are no such problems in single-axis robots. Single-axis robots are generally driven by motors, and the speed can be several meters per second; The shape of the single-axis sliding table is linear, and the required stroke and installation method can be selected according to the actual situation. Compared with the multi-axis robot, the use of space is more flexible.
