Description

[Detailed Description of the Invention] The present invention relates to a masking device for a housing. Conventionally, the masking of the housing has been done by fitting a jig or pasting tape onto the area to be coated with paint. However, this method requires a lot of time because of the large number of cases. Furthermore, there is a problem in that the work becomes complicated because it is necessary to replace the jig for each case. Furthermore, since masking cannot be completed completely, defective products occur. The present invention has been devised in view of these points, and aims to provide a masking device for a case that always performs complete masking, easily performs high-quality coating of the case, and achieves improved workability. be. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the external appearance of an apparatus according to an embodiment, and FIG. 2 is a longitudinal cross-sectional view of the same embodiment. In the figure, 1 is a hollow device body with an open top. A predetermined part of the main body of the device is equipped with an air injection pipe 2.
We are contacting Compressa via . A cock 3 is attached to the air injection pipe 2, allowing operations such as adjusting the amount of air to be injected, exhausting air, and stopping the air injection. An insertion opening 5 for inserting a film 4 is opened in the upper peripheral wall surface of the main body 1 of the apparatus. A film 4 is inserted into the insertion opening 5 so as to pass through the main body 1 of the apparatus. The film 4 is made of a material with high elasticity so that it can be closely attached to housings of various shapes, and is also made of a material with excellent solvent resistance so as not to be deteriorated by the solvent in the paint. There is. Both ends of the film 4 are wound onto a film roll 7 via a roll 6. Rubber gaskets 8, 8 for fixing the film 4 are attached near the insertion opening 5. A stopper 9 is attached to the peripheral wall above the insertion port 5 for fixing the casing, which is the object to be painted. Masking device 2 for the housing configured in this way
According to No. 0, the casing 21, which is an object to be painted, is inserted into the apparatus main body 1 so that the non-painted surface contacts the film 4. The housing 21 is installed by pressing the film 4 at a predetermined position so that it stretches appropriately, and then fixing it with a stopper 9. After installing the housing 21, the film 4 is fixed with rubber gaskets 8, 8. Next, the pot 3 is opened and a predetermined amount of air is supplied from the air injection pipe 2 to bring the film 4 and the casing 21 into close contact. At this time, the film 4 is brought into close contact with the pores of the casing 21 due to the air pressure. In this way, masking with the film 4 can be performed reliably by adjusting the amount of air supplied from the air injection pipe 2. After that, a predetermined paint is sprayed from the opening of the device main body 1, and the coating on the housing 21 is completed. In this way, according to the housing masking device 20 , the film 4 is moved to the housing 2 by the pressing force of the air.
1, it is possible to completely mask the casings 21 of various shapes and easily apply high-quality paint. Further, since the only consumable item is the small amount of film 4, manufacturing costs can be reduced. Moreover, since the adjustment operation only requires setting the film 4 and inserting the housing 21, work efficiency can be improved. Furthermore, the simple structure of the device allows continuous movement through automation. As explained above, according to the masking device for the housing according to the present invention, it is possible to always perform complete masking and apply high quality paint to the housing easily and with high workability. .
