Upper limb industrial exoskeleton actively reducing vibration impact

Abstract

The invention discloses an upper limb industrial exoskeleton actively reducing vibration impact. The upper limb industrial exoskeleton actively reducing the vibration impact includes a clamp for fixing a vibration tool and a wearable part coupled with upper limbs of a human body in a wear mode, and a vibration damping mechanism with a vibration damper as a core part is connected between the clampand the wearable part. The upper limb industrial exoskeleton actively reducing the vibration impact is characterized in that an acceleration sensor is fixed to the inner arc-shaped surface of an arc-shaped clamp of the clamp, and the vibration damper is an active vibration damper; a control device of the active vibration damper is arranged on binding straps capable of being worn on the upper limbsof the human body; and the current output end of the acceleration sensor, the variable stiffness current input end and the variable damping current input end of the active vibration damper are correspondingly connected with the acceleration signal input end, the variable stiffness current output end and the variable damping current output end of the control device. The upper limb industrial exoskeleton has a wide range of applications, has a good damping effect on vibration tools with various vibration frequency and intensity, and can better reduce the vibration impact on the human body.

Description

technical field [0001] The invention relates to an industrial exoskeleton for upper limbs which actively reduces vibration shock. Background technique [0002] There are a large number of manual operation of strong vibration tools (vibration tools) on the industrial production line; for example, workers use impact drills for drilling operations and riveting guns for riveting operations. During operation, these vibrating tools will generate continuous or intermittent vibration, and the resulting vibration impact will act on the human arm; being in such a working environment for a long time will cause rapid fatigue of human muscles and increase the risk of musculoskeletal diseases for workers risk, which typically manifests as a vibrating white finger. [0003] It is possible to work by wearing an industrial exoskeleton that reduces vibration and shock, so as to effectively reduce the impact of vibrating tools on the human body and reduce the risk of illness for workers.

Problems solved by technology

The problem is that it can only passively reduce vibration impact with fixed stiffness and damping, and it can only have a good vibration reduction effect on vibration tools of specific frequency and intensity; to operate different vibration tools, it is necessary to wear corresponding upper limbs. Exoskeletons; limits the application of upper extremity industrial exoskeletons
