High-precision automatic paint sprayer and paint spraying method

Abstract

The invention discloses a high-precision automatic paint sprayer, which comprises a rotary feeding device, a rotary mold changing device, a front mold closing device, a rear mold closing device, a positioning device, a paint spraying device, a cleaning device, a control system and a framework. Two workpiece carrying plates are respectively loaded at two ends of the surface of the rotary feeding device, two mold base fixing seats are respectively fixed at two ends of the surface of the rotary mold changing device, when the mold base fixing seats are aligned to the workpiece carrying plates, the front mold closing device pushes the workpiece carrying plates to ascend and be in mold closing with one mold base fixing seat, a mold closing plate is fixed at the top end of the rear mold closing device, the rear mold closing device pushes the mold closing plate to ascend and be in mold closing with the other mold base fixing seat, the positioning device positions the rotary feeding device and the rotary mold changing device in a locking manner, the paint spraying device sprays paint on workpieces placed on the mold base fixing seats, and the cleaning device cleans and dries the mold base fixing seats. The invention further discloses a paint spraying method realized by the aid of the high-precision automatic paint sprayer.

Description

technical field [0001] The invention relates to a high-precision automatic paint spraying machine, in particular to a high-precision automatic paint spraying machine with simple structure, high degree of automation, precise positioning, high production efficiency and good spraying quality, and a paint spraying machine for spraying paint by using the high-precision automatic paint spraying machine method. Background technique [0002] With the improvement of living standards, the demand for toys is growing at an alarming rate. At the same time, consumers have higher and higher requirements for the appearance of toys, which provides opportunities and challenges for toy processing enterprises. The current toy painting process is becoming more and more complicated, which is reflected in: (1) the increase of local coloring points of toys; (2) the increase of coloring types, and the higher and higher requirements for the position accuracy of local spraying. Therefore, in order to...

Problems solved by technology

[0006] The structure design of the above-mentioned first type of robot is complex, assembly and debugging are difficult, and the gap between the gear and the rack leads to a relatively large error in the position of the feeding and turntable rotation, resulting in low repeatability during feeding, and inaccurate mold clamping with flying oil.

The initial position of the second type of robot is not easy to adjust, the motor control is complicated, and the precision of mold clamping depends entirely on the precision of the cam splitter

In addition, the above two solutions rely on the positioning of the drive itself, without external mechanical auxiliary positioning, and the accuracy of the rotation position is difficult to guarantee
