This non-provisional application claims priority under 35 U.S.C. ยง119(a) on Patent Application No(s). 094222075 filed in Taiwan, R.O.C. on Dec. 16, 2005, the entire contents of which are hereby incorporated by reference.
1. Field of Invention
The invention relates to a coating device, and more particularly, to an automatic coating device driven with a conveyer.
2. Related Art
In view of the foregoing, an objective of the invention is to provide an automatic coating device for an object to be coated automatically, thereby promoting the coating efficiency.
To achieve the above objective, an automatic coating device disclosed herein uses a driving motor and a conveyer to form a cyclically rotating module. An injector filled with a coating material is disposed on one side of the conveyer. When an object to be coated is disposed on the other side of the moving conveyer, the coating material is then applied by the injector onto the object.
An injection opening is form in the conveyer according to the coating shape. When the injector is aimed at the injection opening, the coating material is coated onto the object via the injection opening of the conveyer.
The injector includes a body and an extension board. The body holds the coating material and has an outlet for the coating material to escape from the body. The extension board is connected to the outlet and touches the surface of the conveyer. When the injection opening aligns with the outlet so that the coating material is applied onto the object via the outlet, the extension board pushes the coating material to fill the injection opening. The coating material is thus coated onto the object in accord with the shape of the injection opening.
The disclosed automatic coating device achieves the above goal in an automatic way. Therefore, it has a high coating efficiency, stability, and quality. The extension board provided to pass through the surface of the injection opening enables the coating material to fill the injection opening. Thus, no coating material would be wasted. One can change the thickness and shape of the coating by merely changing the thickness of the conveyer and the shape of the injection opening. Consequently, the disclosed automatic coating device has the advantages of fast coating and highly adaptive for different products.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
The present invention will become more fully understood from the detailed description given hereinbelow illustration only, and thus are not limitative of the present invention, and wherein:
Referring to
The injector 550 includes a body 551 and an extension board 553. The body 551 accommodates the coating material 570. The body 551 is formed with an outlet 552, through which the coating material 570 leaves the body 551. The extension board 553 is protruded from the body 551 and beside the outlet 552 so that the surface of the extension board 553 touches the surface of the conveyer 530. When the injection opening 531 aligns with the outlet 552 for applying the coating material 570 onto the object 300 via the outlet 552, the extension board 553 pushes the coating material 570 to fill the injection opening 531 until the coating is completed.

Therefore, the automatic coating device 500 of the present invention can replace the time-consuming manual coating. It can increase the coating efficiency and quality. On the other hand, using the extension board to pass through the surface of the injection opening enables the coating material to fill the entire injection opening without wasting. Changing the thickness of the conveyer changes the thickness of coating. Changing the shape of the injection opening also changes the shape of the coating material. Therefore, in addition to rapid coating, the disclosed automatic coating device has the advantage of being adaptive for different products.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
