Damping system used for mechanical arm tail end detection sensor

Abstract

The invention discloses a damping system used for a mechanical arm tail end detection sensor, and relates to the technical field of mechanical arm intelligent detection. The damping system comprises an amplitude detection sensing module, a fuzzy control system and a control motor module which are connected in sequence, the amplitude detection sensing module is carried on the tail end of a mechanical arm, and used for detecting the amplitude value of the tail end of the mechanical arm, the detected amplitude value is transmitted to the fuzzy control system, the fuzzy control system carries out fuzzification on the received amplitude value, according to the pre-formulated fuzzy rule, the change condition of the control motor module is judged, and a speed control instruction is output to the control motor module; the control motor module adjusts the self running condition according to the received speed control instruction; and the amplitude is fed back through the amplitude detection sensing module, through a fuzzy controller, the speeds of the mechanical arm in the horizontal direction and the vertical direction are controlled for ensuring that the amplitude of the tail end of the mechanical arm is within the allowable range, it is ensured that the mechanical arm can rapidly reach the designated position to be detected, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent detection of a mechanical arm, and more particularly relates to a shock absorption system for a detection sensor at the end of a mechanical arm. Background technique [0002] Nowadays, robotic arms are widely used in industry. In some dangerous workplaces and some unmanned areas, it has become a routine detection method to use sensors equipped with robotic arms to detect various equipment. However, when the robot arm is equipped with sensors to detect various equipment, the movement of the robot arm causes vibration at the end of the robot arm. When the vibration exceeds the allowable range of the detection sensor, it will affect the detection accuracy. Large impact, while excessive amplitude will shorten the service life of the sensor. [0003] The existing vibration suppression method at the end of the mechanical arm uses a sensor to detect the vibration at the end of the mechanical arm. Wh...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that when the end of the mechanical arm is equipped with a sensor for detection, because the vibration is greater than the critical value, it is necessary to stop the movement of the mechanical arm to suppress the vibration, and it takes a long time to wait for the vibration to be eliminated, resulting in a decrease in detection efficiency.
