Abstract

PURPOSE:To obtain a rubber stopper for masking adequate for an automatic masking operation by providing a head part of the diameter larger than the diameter of a tapered main body part integrally to the upper part of said main body part via a short cylindrical part and providing a recess to be engaged with the tip of a revolving bit atop this head part. CONSTITUTION:The short cylindrical part 3 is provided integrally to the upper part of the tapered main body part 1 consisting of, for example, neoprene rubber, etc. The recess 4 of, for example, a cruciform shape, to be engaged with the tip of the revolving bit is provided atop this head part 3 to form the rubber stopper for masking. Since the large-diameter head part 3 is provided to this rubber stopper, the rubber stopper is easy to be mechanically gripped and easily prevents misalignment and deformation. Further, the recess 4 engages with the tip of the revolving bit and, therefore, the rubber stopper can be pushed into the hole not only by merely pressing the same into the hole of the work but by rotating the stopper as well. Namely, this rubber stopper for masking is adequate for the automatic masking operation.

欠点があった。(Prior Art) Rubber stoppers for masking for the purpose as described above have been known from the past, as shown in, for example, Japanese Utility Model Application Laid-Open No. 62-55567. However, conventional rubber stoppers are simply conical or cone-shaped, and must be manually inserted into holes in the work piece one by one, which has the drawback of requiring a lot of time and effort for masking work. Furthermore, Japanese Patent Laid-Open No. 60-206189 discloses a device for automatically attaching this type of masking rubber plug to a workpiece.The mechanism for taking the rubber plug from the magazine and attaching it to the workpiece is complicated. Moreover, since the rubber stopper is simply inserted into the hole in the workpiece, the rubber stopper may come off or masking may be incomplete, and processing liquids such as plating solution may enter the hole in the workpiece and cause oxidation, resulting in defective products. There were disadvantages such as that it could occur.

This allows for more reliable masking compared to the conventional type that is simply pressed. In addition, since the head is formed to have a larger diameter than the main body, it is easy to grip with chuck claws, etc., and it is suitable for automatic masking work because it prevents misalignment fluctuations from being scratched by insects.
The attachment device of the present invention is capable of automatically attaching the masking rubber plug as described above to the workpiece, and in connection with the fact that a pressure feeding method using air pressure is adopted for supplying the masking rubber plug, Masking work can be performed extremely efficiently. Therefore, the present invention greatly contributes to the development of industry as a rubber plug for masking and its mounting device that eliminates the problems of the conventional technology.
