Description

561069 V. Description of the invention (1) [Description of the invention] Wei Zuo ?: It is about a rotary painting method, especially-a method that can paint on the object with an arc-shaped trajectory. [Background of the invention] Button eyepieces are widely used, such as for mobile phone cases, gukou and other products, to improve the aesthetics of the product. For coating = mode, it is roughly divided into manual coating and Robot outfitters: The painters are directly spraying and grabbing by hand. V ,,: ==: loading, generally when painting the objects, when the first time to the left and right to rotate the work 90 degrees , And the same way for the third or fourth time; === the same painting square knife daggers 衮 衮 衮 Cai Fancheng into the painting operation, because it is carried out by people, such as this painting operation will have the following Disadvantages 1. Operation is slow and extremely inefficient. 2. The paint applied on the surface of the work cannot be uniform. 3. Quality cannot be accurately controlled. 4 · When the negligence of manual operation is performed on the plane with high and low drop, such as the uneven surface, the dead corner of the painting is generated, which makes the painting inaccurate: 'easy because of this, most of the above problems are generally solved by machine coating methods = problems, As shown in the first figure, when a human is traveling on a trajectory based on a machine, the painting work is performed on a work object (w with, ^ parallel to each other's painting trajectory (this time, the first time is shown as U "), When the first painting job is completed, the work (trace) 561069 V. Description of the invention (2) Rotate 90 degrees to perform the second painting, as shown in the second picture (this second time The painting trajectory is marked as (a2)). The painting trajectory this time will be perpendicular to the first painting trajectory. After the completion, the work will be rotated 90 degrees each time and the same The painting method is performed for the third time (as shown in the third picture, the third painting track is marked as (a3)) and the fourth time (as shown in the fourth picture, the fourth painting track is marked as (A4)), the third painting track (a3) will be the same as the first painting track ai) overlap, and the fourth painting trajectory (a4) will be the same as the second painting trajectory (a2). If the working object (ff) is partially enlarged and observed (as shown in the fifth figure)广 ， 'The coating surface of the work (W) has orthogonal or parallel overlapping of the paint coating trajectory. When spraying in the direction of I, the air current of Kadoto A passes through the uneven interface, the shading of the raised surface will be caused by the X 疋 '^ of the raised surface. The effect of complete coating makes the coating uneven; while the shortcomings of the dead-end mounting method are obvious... The visual intent is mechanical automatic coating. In view of this, the inventor of this case has studied the innovative rotary coating method and its device. Can't Exhaust [Purpose of this creation] The purpose of this creation is to provide a paint spraying device of a rotary coating device in a cantilever and two methods. When painting, the paint spraying device can follow the cantilever. … Y, the device installed on the start-up object passes the coating in a straight direction and wants to paint. Manner as to trace an arc to the work of painting i The paint spray gun for coating work object into the Ding, the case

IM1 $ 5 pages 561069 V. Description of the invention (3) When the work object is rotated 90 degrees each time and is applied for many times, there will be two or more differences on the surface of the work object. The trajectory of the coating can effectively eliminate the dead corner of the coating and make the coating more uniform. The desirable entities of the present invention are made clear by the following description and the accompanying drawings. [Technical content of this creation] Please refer to the sixth to eleventh diagrams. The present invention relates to a rotary coating method. The paint spraying (1) of the coating device (100) is mounted on a cantilever. (2), when the coating device is started, the paint spraying (1) can rotate with a cantilever (2) around a rotary spindle (3), and the work object (4) to be painted is in a straight line The direction passes below the paint spray gun (〗), so that the paint spray grab (1) has an arc trajectory to paint the work object (4). '' The above coating device (100), wherein the paint spraying (丨) is connected with an atomizing air supply pipe (11), a paint supply pipe (12) and a spray control air supplying pipe 03) 'wherein the atomization The gas supply pipe (11) and the middle part of the spray control supply pipe (13) are connected to a gas supply rotary relay (10a), and the paint supply pipe (12) is connected to a paint supply rotary relay (10b) ), And the rotating main shaft is a driving motor (14) in conjunction with the spinner. In the present invention, the disclosed coating device (100), wherein a single paint spraying (1) or a plurality of paint spraying (1) can be installed on the cantilever (2), the present invention is not self-limiting . The rotary coating method disclosed by the present invention, when the coating device

561069 V. Description of the invention (4) (100) After starting, each of the paint spray grabs (1) rotates along the cantilever (2) around the rotary main shaft (3), and the work object (4) can be obtained by Conveyor belts (not shown) and other conveying devices drive the work object (4) to pass under the area covered by the paint spray grab (1). If so, the surface of the work object (4) can be produced as As shown in the figure 7, the painting trajectory of a continuous succession elliptic curve. This first painting trajectory (L1) is a parallel solitary curve on the work object (4). When the work object (4) After finishing the first painting, you can rotate the work object (4) by an angle (such as 90 degrees), as shown in Figure 8, and then perform another painting operation 'this second painting The trajectory (L2) is in a staggered pattern with the previous first painting trajectory (L1). When the work object (4) is rotated ninety degrees each time, after multiple coating operations, such as the ninth, As shown in Figure 10, a variety of coating rails of different directions can be generated on the coating surface of the work object (4) (L3: the third coating trajectory) ; [4: the fourth painting track), as shown in the eleventh figure, since the painting track (1) [, l2 formed on the work object (4) after multiple paintings , L3 and L4) 'The elements are all ridged arc-shaped staggered in different directions, that is, when painting, the paint can be sprayed to the work object at different angles and directions, so that the paint can be smoothly sprayed onto the work object. The position of each point on the concave and convex surface can greatly reduce the dead angle of painting. In addition, it can generate a denser paint trajectory on the painting surface of the work object, making the painting effect more uniform *. The coating method disclosed in the present invention is applied to a work object, and the coating method disclosed in the habit of applying paint to a work object is different from that of the coating method. The coating trajectory of the formula will know the mechanical coating method. Therefore, the present invention applies multi-angle coating to work objects.
