Description
Technical Field
The application relates to the technical field of spraying, in particular to an automatic hopper spraying method.
Background
The spraying mode can be one of gas spraying, high-pressure airless spraying or electrostatic spraying, and can be automatic reciprocating spraying, passing-through type automatic spraying or robot spraying, etc.
Wherein, the electrostatic spraying can be combined with air-mixed spraying, and the advantages of the electrostatic spraying and the air-mixed spraying are combined into a novel spraying method. When a DC high voltage is applied between the grounded workpiece and the spray gun, an electrostatic field is generated, and when negatively charged paint particles are sprayed to the workpiece, the paint particles are uniformly deposited on the surface of the workpiece through mutual collision, and the paint particles scattered near the workpiece are still in the action range of the electrostatic field and can encircle the periphery of the workpiece, so that all surfaces of the workpiece are sprayed. Therefore, the coating is particularly suitable for spraying workpieces with complex geometric shapes, such as fences, pipelines, small-sized steel structural members, steel pipe products, hardware, spectacle frames, ornaments and the like and small surface areas, can conveniently and rapidly spray the coating on each place of the workpieces, and can reduce the overspray of the coating and save the coating. The coating transfer efficiency is as high as 60-85%, the atomization condition is good, the thickness of the coating is uniform, and the improvement of the product quality is facilitated.
The surface of the workpiece is sprayed with a coating, which can effectively improve the corrosion resistance of the workpiece material, prolong the service life of the workpiece and the like, is widely applied to the protection of a vehicle carriage, the carriage is generally required to have uniform thickness and stable quality and consists of a bottom plate, a front plate, a turnover rear plate, a left side plate and a right side plate, 10 surfaces to be sprayed are arranged inside and outside, the inner wall and the outer wall of the carriage are respectively and independently sprayed in the conventional spraying process,
in addition, in the actual spraying process, a manual spraying mode is adopted, and the spraying habit and the operation proficiency of operators are different, so that the uniform thickness and the stable quality of the coating are difficult to ensure, and the spraying of all the surfaces is sequentially carried out in sequence, so that the spraying of one part is required to be completed, and then the spraying of the other part is required to be carried out; the arrangement of the spraying stations, the spraying nodes of the spray gun and the spraying track of the spray gun is unreasonable, so that the spraying efficiency is low. The coating quality is unstable and may lead to premature failure of part of the coating.
In terms of improving the quality stability of the coating, although the mechanical arm spraying has irreplaceable advantages compared with manual spraying, the robot spraying has difficult track teaching of the connecting ring, the automatic powdering effect is poor, and the manual supplementary spraying amount is larger; moreover, in terms of spraying efficiency, the number of spray guns loaded by a single robot is generally less than 3, and the number of spray guns is difficult to finish spraying with a large area in a production beat; the robot has complex mechanism and high maintenance difficulty.
Therefore, the automatic reciprocating spraying and the passing-through automatic spraying are used, and the automatic spraying combining the two modes is the development direction for solving the quality stability of the carriage surface coating and improving the spraying efficiency.
