An industrial robot that overcomes electrostatic gravity and automatically sprays micron-sized solid particles

Abstract

The invention discloses an industrial robot capable of overcoming electrostatic attraction and automatically spraying micron-size solid particles, and belongs to the field of ultrafine solid particlespraying robots. The industrial robot comprises a ball screw and a guide rod which are installed between a machine frame base and an upper machine frame, a container base installed on rolling nuts, nflexible material proportioning devices of the same structure, a motor A and n material proportioning containers, wherein the motor A is installed on a motor A frame, and an output shaft of the motorA is connected with one end of the ball screw. The flexible material proportioning device comprises a flexible vibrating frame, an eccentric motor, a motor B frame, a material proportioning barrel, arotary valve and a motor B, wherein the rotary valve and the motor B are arranged inside the material proportioning barrel. A large number of micron-size solid particles are arranged in the material proportioning barrel. When the eccentric motor works, the amplitude of the flexible vibrating frame in the vertical direction is five or more times that of the flexible vibrating frame in the horizontal direction. The industrial robot can overcome electrostatic attraction and achieve automatic spraying of ultrafine solid particle powder, especially micro-size solid particle powder through eccentricvibration.

Description

technical field [0001] The invention belongs to the field of superfine solid particle spraying robots, in particular to an industrial robot which overcomes electrostatic gravity and automatically sprays micron-sized solid particles. Background technique [0002] The use of robots to realize the automatic spraying of solid particle powder has become one of the trends in the development of automation. In the existing technology, the automatic spraying of larger solid particles is usually achieved by using a rotary valve, because the gravity of such particles is much greater than the electrostatic attraction. However, for ultra-fine solid particles, especially micron-sized solid particles, although the circular hole of the rotary valve is larger than the diameter of the solid particles, the gravitational force and electrostatic attraction of the solid particles are too small, so that it cannot be implemented.
