Description

technical field [0001] The invention relates to a linear reciprocating device, in particular to a mechanical linear reciprocating synchronization device. Background technique [0002] On the production line, the manipulator often needs to do reciprocating linear motion to operate the products on the conveyor belt. At the same time, the feeding device must keep synchronous feeding with the manipulator and the conveyor belt. Currently, the motion controller is commonly used to control the conveyor belt, manipulator and feeding device. Synchronous action, this kind of synchronous control method uses the electronic gear and electronic cam function of the motion controller to realize the control of motion parameters such as displacement, speed, acceleration and so on between the motion axes, and then realizes synchronous action; [0003] This control method has the following disadvantages: [0004] 1. The load capacity is small and the rigidity is low. In the case of heavy load,...

AI Technical Summary

Problems solved by technology

[0004] 1. The load capacity is small and the rigidity is low. In the case of heavy load, the actuator such as servo motor or stepper motor is prone to hysteresis or step loss, that is, the heavy load accuracy is low;

[0005] 2. During high-speed motion, the lag of synchronous motion becomes more obvious

[0006] 3. The motion characteristics are poor, and it is easy to generate shock and vibration. Most of the motion controllers now control the displacement, speed and acceleration of a motion axis, while the jerk characteristic (jerk) that characterizes the motion characteristics of shock and vibration is rarely controlled. , which makes the shock and vibration obvious during high-speed motion. On the other hand, due to the lag of motion, the motion controller needs to perform an interpolation operation after executing one or more control cycles to correct the motion deviation. The correction needs to be realized by changing the magnitude and direction of the force or torque, and the change of this force or torque also makes the dynamics of synchronous motion worse
