Coating burr removal method after coating

The invention relates to a method for removing burrs, in particular to a method for removing burrs after coating.

In the general coating process, in order to prevent the object to be displaced during the process of the coating, the glue is usually used to fix the object to be plated and the bearing fixture, and the portion of the non-coated area, and then the subsequent coating step, however, Since the plated material and the rubber material are a continuous film layer after the coating, the separation of the object to be coated and the rubber material is likely to result in an uneven section due to the viscosity of the rubber material itself. That is, the burr of the plating layer or a part of the film layer is directly peeled off from the surface of the object to be plated, resulting in underplating.

In order to improve the phenomenon of burrs of the coating, a conventional improvement method is to use a less viscous glue to fix the object to be plated. However, due to insufficient adhesion of the glue, a portion such as a plated object or a non-coated portion may be generated. Produce overflow plating. Another improvement method is to remove the burrs by brushing, roller, plastic sheet, etc. at a position where the object to be plated is separated from the glue after the object to be plated is separated from the glue. However, this method may scratch the surface of the object to be plated or the surface of the coating, or the burr after removal may be due to static electricity or For other reasons, it is repeatedly applied to other parts of the object to be plated, which may result in the need to remove the burrs again or require additional processing. The above-mentioned conventional improvement methods may cause defective products, which not only causes a decrease in the yield of the process, but also takes more time and manufacturing costs.

Accordingly, it is an object of the present invention to provide a method for removing burrs after coating which can save manpower, time and equipment costs, and improve yield.

Therefore, the method for removing the burr of the coating after the coating of the present invention comprises the following steps: (A) preparing a pedestal, a soft rubber material disposed on the top surface of the pedestal, a pressing device, a coating device, and a transporting device. The conveying device of the base, the soft rubber material has a thickness, and the pressing device comprises at least one pressing rod for fixing at least one component to the top surface of the soft rubber material. (B) transporting the susceptor into the coating device by the conveying device, and forming a continuous coating layer on the soft rubber material and the at least one component. (C) transporting the susceptor away from the coating device by the conveying device, and conveying the pedestal to the lower portion of the pressing device, the at least one pressing rod of the pressing device is directed to a certain amount of downward pressure Moving downward, and after pressing the at least one component, pressing down the pressing depth, and then moving upward to a position not contacting the at least one component, thus repeating several times, the pressing depth is less than that of the soft rubber material thickness. (D) removing at least one component from the soft gel.

The effect of the present invention is that the element is pressed by the at least one pressure bar of the pressing device, and the at least one component fixed to the soft rubber material is pressed downward due to the elasticity of the soft rubber material. After being pressed several times, the portion of the continuous coating layer adjacent to the outer peripheral side of the at least one component in contact with the soft rubber material is subjected to a shearing force to form a flat cross section, and the at least one component is taken from the soft rubber material. After that, the coating layer on the surface of the at least one component does not have burrs, so that no additional deburring operation is required, which can greatly improve the yield and reduce labor, time and equipment costs.

As shown in FIG. 1, an embodiment of a method for removing a burr of a coated film after coating according to the present invention comprises the following steps:

Step S100: Referring to FIGS. 2 to 4, a susceptor 1, a soft rubber material 2 disposed on the top surface of the susceptor 1, a pressure reducing device 3, a coating device 4, a reclaiming device 5, and the like are prepared. The flexible adhesive material 2 has a thickness of 0.7-0.8 mm, and the soft rubber material 2 has an adhesive layer on the top surface thereof, and includes a plurality of through holes 21 extending through the top and bottom surfaces. The pressing device 3 includes a plurality of pressing rods 31. The reclaiming device 5 includes a plurality of ejector pins 51. The conveying device 6 includes a first conveying unit 61 disposed on the pressing device 3, and a first setting unit disposed on the coating device 4. The second transport unit 62 fixes the plurality of components 8 to the top surface of the soft rubber material 2 in a manner corresponding to the positions of the through holes 21, and the components 8 are placed by using a feeder (not shown). The components 8 are arranged in a plurality of rows.

Step S200: the pressure bars 31 of the pressing device 3 press the components 8 downwards once, so that the components 8 are more firmly adhered and fixed to the soft rubber 2, in the embodiment, the same The pressing rod 31 presses the elements 8 in a downward pressing manner in which one of the horizontal rows is pressed once.

Step S300: Referring to FIGS. 2 and 5, the susceptor 1 is transported into the coating device 4 by the second conveying unit 62 of the conveying device 6, and a soft rubber material 2 and the components 8 are formed. In the present embodiment, the continuous plating layer 9 has a thickness of 3 to 10 μm.

Step S400: Referring to FIG. 2, the susceptor 1 is transported away from the coating device 4 by the second conveying unit 62 of the conveying device 6, and the pedestal 1 is taken by the first conveying unit 61 of the conveying device 6.
