Precision fully-automatic coating equipment

Abstract

The invention discloses precision fully-automatic coating equipment, which comprises a powder cabinet electric control box, a powder cabinet, a worktable, a powder spray gun and a clamping device, wherein the powder spray gun is arranged at the center of the inside of the powder cabinet; the clamping device comprises two ejector devices, two masks and a movable device; the ejector devices have ejector pins and driving mechanisms for driving the ejector pins to rotate; the two ejector devices are symmetrically fixed on the movable device under the two sides of the powder spray gun; the ejectorpins of the ejector devices are in the same line; the two masks are sleeved outside the ejector pins of the two ejector devices respectively and can slide along the axial direction of the ejector pins; the movable device is arranged on the worktable in a sliding mode; and the powder cabinet electric control box is electrically connected with the powder spray gun, the ejector devices and the movable device respectively. The precision fully-automatic coating equipment has the advantages of uniform spray coating, high raw material utilization rate, full automation and extremely high precision interms of coating shaft-like workpieces.

Description

technical field [0001] The invention relates to a coating device, in particular to a precision automatic device for spraying powder on a shaft-shaped workpiece. Background technique [0002] At present, the coating methods on the surface of metal workpieces include spraying, brushing and dip coating. The method of spraying the workpiece by manual operation not only makes the labor intensity of the workers too high, but also the production efficiency is very low, and there are human subjective factors in the manual spraying process, so the places that do not need to be sprayed are easy to stick to the powder. Therefore, manual The spraying accuracy of the spraying on the workpiece is not good, and it is easy to cause uneven spraying. [0003] In addition, although the mechanical spraying method can reduce the amount of manual work and improve production efficiency, it still has the disadvantages of uneven spraying and uneven coating thickness, and the spraying effect is not ...

Problems solved by technology

[0002] At present, the coating methods on the surface of metal workpieces include spraying, brushing and dip coating. The method of spraying the workpiece by manual operation not only makes the labor intensity of the workers too high, but also the production efficiency is very low, and there are human subjective factors in the manual spraying process, so the places that do not need to be sprayed are easy to stick to the powder. Therefore, manual The spraying accuracy of the spraying on the workpiece is not good, and it is easy to cause uneven spraying

[0003] In addition, although the mechanical spraying method can reduce the amount of manual work and improve production efficiency, it still has the disadvantages of uneven spraying and uneven coating thickness, and the spraying effect is not ideal. For example, some spraying equipment adopts the method of hanging multiple workpieces. The method of batch spraying requires a large number of workpieces to be processed at one time, but the suspended workpiece is easy to sway and shake; especially when the shaft-shaped workpiece is sprayed in a suspended manner, due to the slenderness of the shaft-shaped workpiece itself, the shaft The shaft-shaped workpiece swings and shakes more severely, and the shaft-shaped workpiece is placed vertically so that the drop between the shaft-shaped workpiece and the powder spray gun is large, and it cannot directly face the powder spray gun, resulting in the coating thickness of the shaft-shaped workpiece being different during the spraying process. 1. The phenomenon of uneven spraying or missing spraying will affect the spraying quality of the workpiece
