An automatic spraying device

Abstract

The invention discloses an automatic spraying device, which comprises a six-axis robot, a connecting frame, a mounting frame, a fixed rod, a spray gun and a driving assembly; the connecting frame is fixedly connected to the mounting end of the six-axis robot; one end of the mounting frame is fixedly connected to the connecting frame; The number of fixed rods is multiple, and the end is hinged with the other end of the mounting frame, and the connection points of multiple fixed rods and the mounting frame are evenly spaced along the edge of the mounting frame; the spray gun is fixed at the end of the free end of the fixed rod; the drive assembly It is connected with the installation frame, and is used to simultaneously drive multiple fixed rods to expand outward or contract inward. The present invention improves the painting rate of the painted parts by arranging multiple spray guns on the same mounting frame. Since the spray surfaces of the spray guns are on the same horizontal plane, there will be no uneven spray thickness, and through the control of the drive assembly, It can realize the adjustment of multiple spray guns at different angles, and then adapt to spraying products with different needs, with high spraying efficiency and low cost.

Description

technical field [0001] The invention relates to the technical field of automatic spraying, in particular to an automatic spraying device. Background technique [0002] At present, the spraying process is a routine process that can be touched in mechanical manufacturing and daily life. Although spray-painted products can be found everywhere, spraying is an extremely complex operation technique. With the advancement of science and technology, manual spraying has gradually faded out, replaced by automated spraying equipment, which effectively ensures the consistency of spraying and reduces the harm of toxic gases from paint to the human body. [0003] The spray gun in the automatic spraying equipment plays a vital role in spraying. The existing spray gun is a conventional pneumatic spray gun or a rotary cup spray gun. The paint utilization rate of the pneumatic spray gun is low, which can only reach 30%-40%. It leads to a low paint rate, which affects the spraying efficiency,...

Problems solved by technology

[0003] The spray gun in the automatic spraying equipment plays a vital role in spraying. The existing spray gun is a conventional pneumatic spray gun or a rotary cup spray gun. The paint utilization rate of the pneumatic spray gun is low, which can only reach 30%-40%. It leads to a low paint rate, which affects the spraying efficiency, but its cost is low; the spraying efficiency of the rotary cup is high, the paint utilization rate can reach more than 70%, and the paint rate is high, but the spraying of the rotary cup is generated by high-speed rotation. Paint spraying by centrifugal force, the purchase and maintenance costs are also high, and the rotary cup spraying needs to rely on electrostatic adsorption to achieve painting, the requirements for spraying fixtures are also high, and the use is more cumbersome
