Electrically-controlled tail-end-steerable mechanical arm

Abstract

The invention provides an electrically-controlled tail-end-steerable mechanical arm. The electrically-controlled tail-end-steerable mechanical arm comprises a mechanical arm module and a painting module, wherein a driving element of the mechanical arm module is arranged on a platform at the bottom part; a first arm and a second arm do not have additional weight, excepting dead weight and the weight of supporting connecting rods, so that the characteristics such as quick moving of a tail end are realized; a working tail end which can be gyrated and rotated on own axis is mounted on the tail endof the second arm, thus the freedom of motion is increased, and various working demands are met; a gyrating driving assembly and a rotating driving assembly at the working tail end are mounted on theplatform, and moving parts of the driving assemblies are lighter than an existing mechanical arm; a painting head of the painting module is provided with pressure maintaining measures, the painting can be continuously performed for a while in case of material cutting off by accident, and thus unqualified products caused by material cutting off can be avoided; the painting head has the heating function and is capable of heating paint, so that the air temperature is increased while the atomizing effect of the paint is increased, and the paint can be quickly dried by air.

Description

technical field [0001] The invention relates to the field of robots, in particular to an electronically controlled terminal steerable machine arm. Background technique [0002] Robots can be divided into parallel robots and serial robots. Among them, the common type of serial robots is articulated robots. In common articulated robots, the driving components of each arm are installed on the joints connected to the forearm. As the number of arms increases, the load on each arm will increase accordingly, resulting in an increase in the volume of the driving power components of the arm and an increase in the movement speed of the arm. Problems such as slowing down and reducing the accuracy of the arm are not conducive to the high-speed and miniaturization of joint robots. [0003] The use of robots for painting operations is more common in robot applications. During the painting process, if an accident such as a material outage occurs and the paint supply is cut off, even if th...

Problems solved by technology

In common articulated robots, the driving components of each arm are installed on the joints connected to the forearm. As the number of arms increases, the load on each arm will increase accordingly, resulting in an increase in the volume of the driving power components of the arm and an increase in the movement speed of the arm. Problems such as slowing down and reducing the accuracy of the arm are not conducive to the high-speed and miniaturization of joint robots

[0003] The use of robots for painting operations is more common in robot applications. During the painting process, if an accident such as a material outage occurs and the paint supply is cut off, even if the parts in the job are repainted, due to the different drying time of the paint, the new paint There will be uneven transition marks at the junction with the old paint, and the parts can only be scrapped or reprocessed, which is a waste of cost
