Problems solved by technology

[0008] The unevenness caused by the difference in the thickness of the coating film will cause the difference in the coating quality such as the gloss and color of the coating surface, and it will also cause the processing defect in the secondary processing of the coating surface, which is the cause of many problems.
[0009] This problem can be improved if the objects to be coated that are arranged in a circumferential shape are painted at the same angle with respect to the spray gun, but this requires an enlarged rotary table, which is actually difficult to adopt due to equipment limitations. Not practical

Embodiment Construction

[0023] Hereinafter, the present invention will be described with reference to the accompanying drawings. As an example of rotary coating figure 1 The objects 3 and 4 to be painted which are painted by the spray gun 2 are each mounted on a jig 6 which is circumferentially arranged on the rotating table 5 . The jig 6 is in the shape of a flat plate, and is mounted on the concentric circle of the above-mentioned table 5 in parallel to the tangent thereof, and can be freely attached and detached as required. This example is an example in which eight jigs 6 are installed.

[0024] The installation position of the spray gun and the direction of the spray axis are provided in a position parallel to and eccentric from the center of rotation, and have a positional relationship in which the object to be painted is painted from an oblique direction. Furthermore, when the upper and lower surfaces of the object to be coated need to be painted, the spray gun is sprayed with the upper and...

Abstract

The invention relates to a rotary automatic coating method, which is characterized in that: a rotary coating can be implemented by reducing the interval configuration of the object to be coated in relation to the side of the coated object with more coating, so the coated object in the front can be covered. The workpiece pitch at an adjacent flat is less than the workpiece pitch at the flat in relation to the coating object arranged on the flat. As an alternative method, a rotating device for straight line movement area is arranged at the spraying and coating area, and the rotating device is rotated without the influence of spraying angle. The rotary automatic coating method has the advantages of maintaining the effect of rotary coating, and improving the uniformity of the paint film and the coating quality .

Description

technical field [0001] The present invention relates to rotary painting in which the objects to be painted are circumferentially arranged on a rotating table for painting in batches of small objects to be painted such as mobile phones and cameras. In particular, it relates to an improved coating method and apparatus when the spray guns arranged to coat the coating surface at different angles and film thicknesses are different depending on the object to be coated. Background technique [0002] Rotary painting is to rotate the objects to be painted arranged on the circumference, and use the spray gun to spray the objects to be painted one by one into the painting spray area during this period. This method is very productive. is used in many ways. The coating method and conditions are selected according to the shape of the object to be coated and the required quality of the coating film, paint, etc., but generally the following process is used to uniformly coat the left and ri...
