Large-area paint spraying robot for vehicle surface spraying

Abstract

The invention relates to the technical field of industrial robots, in particular to a large-area paint spraying robot for vehicle surface spraying. A mechanical arm fixing support is fixed to the upper end of a rotary chassis, a servo motor is connected to the left side of the mechanical arm fixing support, and a primary mechanical arm, a secondary mechanical arm and a ternary mechanical arm are sequentially connected to the upper end of the mechanical arm fixing support; a plurality of hydraulic lifting pillars are connected to the lower end of the rotary chassis, a hydraulic driving motor is connected to one side of the hydraulic lifting pillars, and the lower ends of the hydraulic lifting pillars are fixed to a fixed base. The robot is characterized in that the middle of the ternary mechanical arm is sleeved with an oil paint conveying box, the front end of the ternary mechanical arm is connected with a plate type paint spraying device through a rotary connecting part, a plurality of paint spraying holes are formed in the surface of the plate type paint spraying device, and the plate type paint spraying device is connected with the oil paint conveying box through a conveying pipe. The robot is simple in structure and novel in design. Through the cooperation of the plate type paint spraying device and the multiple paint spraying holes, large-area paint spraying of the surface of a vehicle body can be achieved quickly, paint spraying efficiency is improved, the number of devices is reduced, and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of industrial robots, in particular to a large-area painting robot for automobile surface spraying. Background technique [0002] With the development of society, people's living standards continue to improve, and various new products come one after another and enter people's lives. With the development of the economy, my country has gradually transitioned from the era of low labor costs to the era of high costs. Due to the increase in labor costs, the cost of use by enterprises has also increased greatly. Facing fierce competition, enterprises have to consider reducing labor costs. Therefore, it has become an inevitable trend to use industrial robots instead of labor. [0003] Industrial robot is a kind of automation equipment with high degree of automation and work efficiency. Its work is controlled by pre-set programs and fixedly completes the same action. These industrial robots are widely used in automo...
