A mobile electro-hydraulic composite drive spraying robot with large working space

Abstract

The invention discloses a movable electro-hydraulic composite driving spraying robot with a large working space, which comprises a mobile base, wherein there are multiple mobile bases, which are cooperatively arranged to carry a driving rope adjustment module, The profile pillars in the driving rope adjustment module are respectively fixed on the mobile bases, and a plurality of mobile bases are enclosed to form an operation space, and a movable adjustable auxiliary motion platform is erected inside the operation space, and the adjustable auxiliary motion platform There is a rotary motion platform below, the adjustable auxiliary motion platform is connected with the rotary motion platform through a hydraulic push rod, the bottom end face of the rotary motion platform is installed with a spray gun, and the mobile base is also installed with a rope for balancing the traction force and maintaining the balance of the mechanism. Balance mechanism and fixed support mechanism. The invention has a reasonable structure design, realizes multi-degree-of-freedom motion in a larger working space, avoids the interference between the traction rope and the processing workpiece, and improves the applicability of the equipment.

Description

Technical field: [0001] The invention relates to the field of robots, and mainly relates to a movable electro-hydraulic compound driving spraying robot with a large working space. Background technique: [0002] Spraying can bring the advantages of anti-rust and anti-corrosion to the workpiece to be processed, and can improve its appearance at the same time. It has become an indispensable process in all walks of life. In traditional industrial production, manual spraying is mainly used. However, manual spraying will bring certain harm to workers, and at the same time, the work efficiency is low, and the spraying quality is difficult to guarantee. Therefore, spraying robots are constantly replacing traditional manual spraying to achieve the purpose of improving production efficiency and ensuring stable product quality. [0003] The existing spraying robots are mainly tandem rigid robots, and most of them use the solution of adding spray guns to the serial manipulators. The po...

However, when the existing flexible cable drive mechanism faces complex surfaces, the drive cable easily interferes with the workpiece to be processed, which interferes with the spraying process

For example, the Chinese invention patent with the application number 202010243575.1: a cable-driven hybrid spraying robot mechanism and its operation method. The main body of the mechanism is driven by a rope and has the advantages of a large working space. The end spray gun is not flexible enough, and there may be interference between the driving rope and the workpiece at the same time; the Chinese invention patent with the application number 201910641158. The orbit is limited, and the actual movement form of its end is close to the series mechanical arm, and its working space is limited to a certain extent; the Chinese invention patent with the application number CN201811064098.1: a rope traction parallel spraying robot on the outer surface of the hull, the mechanism is mainly for The curved surfaces on both sides of the ship have relatively low flexibility at the end, and the mechanism is not universal
