Description

Surface treatment device

The present invention relates to a surface treatment apparatus, and more particularly to a surface treatment apparatus for smoothing the surface of a three-dimensionally shaped article.

In recent years, rapid prototyping (RP technology) has been developed based on the concept of building pyramid layer stacking, which can automatically and quickly design any complex shape without any tools, molds and fixtures. The graphics are quickly converted from flat 2D to 3D solid solid shaped objects.

Three-dimensionally shaped articles made by rapid prototyping techniques typically exhibit a "stepped" non-flat appearance due to the process of layer-by-layer stacking, particularly on curved or slanted exterior surfaces. The effect of causing the three-dimensionally shaped object to have a step shape is that the cross-sectional edges of the three-dimensionally shaped articles are layered at right angles, and in addition to the uneven appearance, the thickness of the three-dimensionally shaped article is increased.

The above-mentioned stepped non-flat appearance will constitute a disadvantage in the appearance of the three-dimensionally shaped article, and various polishing techniques have been applied to improve the smoothness of the surface of the three-dimensionally shaped article manufactured by the rapid prototyping technique. There is a technique for smoothing the surface of a three-dimensionally shaped article by vapor erosion, such as the vapor surface smoothing system disclosed in U.S. Patent Publication No. US 2009/321972 (A1). However, in the prior art, the three-dimensionally shaped articles are placed in a processing chamber that the user cannot directly see with the naked eye, and the surface treatment is performed in the opaque processing chamber. The user cannot directly observe the condition of the surface treatment, and after the entire surface treatment process is completed, the three-dimensionally shaped object is taken out from the processing chamber to know the condition of the surface treatment of the three-dimensionally shaped object, and thus the three-dimensionally shaped object may be excessively subjected to excessive treatment. The surface is flattened and the distortion or the surface treatment is insufficient to meet the requirement of smoothing the surface of the three-dimensionally shaped object; secondly, the vapor generated by the processing chamber of the existing vapor surface smoothing system is easily concentrated in a certain area, resulting in a situation The entire outer surface of the three-dimensionally shaped article is not uniformly subjected to the flattening treatment of the vapor. Furthermore, the existing vapor surface smoothing system cannot provide the user with individual adjustment of the amount of vapor and/or vapor release duration depending on the requirements of the three-dimensionally shaped article, nor the control conditions such as the amount of vapor or the release time of the vapor. Or the surface treatment precision of the three-dimensional shaped object, providing segmental regulation or fine-tuning, in the case of being unable to monitor the surface treatment process, the shortcoming of the surface smoothing treatment of the three-dimensionally shaped object is often insufficient or the surface smoothing treatment is disadvantageous. Excessive surface treatment will cause the entire three-dimensional shaped object to face the problem of need to be reworked, resulting in cost and time. In addition, the operating panel of the existing vapor surface smoothing system provides very limited mechanical push switches and status displays, such as mechanical push switches only for system opening, shutdown or emergency stop, and only one for each function. The light/dark of the corresponding indicator light indicates the opening or closing of the function. Therefore, the operator is not able to monitor the current situation in time, and cannot perform the above-mentioned segmentation adjustment or fine-tuning operation in time, so that the operation is performed in human-machine operation. The convenience is poor.

The above shortcomings show the shortcomings of the current surface smoothing treatment technology for three-dimensionally shaped articles, and therefore an improved solution for the existing vapor surface smoothing treatment system is required.

In order to solve the above problems of the prior art, one of the aims of the present invention is to provide a The surface treatment device is used for surface treatment of a three-dimensionally shaped object, which not only can timely monitor the current state of the treatment, but also can timely timely deal with various processing conditions such as the amount of steam or the release time of the vapor or the surface treatment precision of the three-dimensionally shaped object. The segmentation regulation or the fine adjustment operation has high convenience in man-machine operation; in addition, the surface treatment device of the present invention can uniformly smooth the entire outer surface of the three-dimensionally shaped article.

The gas surface smoothing system cannot instantly observe the condition of the surface treatment of the three-dimensionally shaped object through visual observation, that is, it is impossible to immediately monitor the surface treatment of the three-dimensionally shaped object, which may lead to the disadvantage of excessive surface treatment or insufficient surface treatment, and The existing vapor surface smoothing system cannot customize the required surface treatment time and the required amount of vapor for the surface area of each three-dimensionally shaped article, the type of construction material, and the size of the article. Compared with the prior art, the surface treatment device provided by the present invention allows the user to instantly monitor and observe the hot steaming condition of the three-dimensional shaped object through the observation side wall, and the control unit sets at least one hot steaming mode to provide different stereoscopic shaped objects. The vapor release amount and the hot steaming time, and the hot steaming condition of the three-dimensionally shaped article can be observed immediately to determine whether the steam release amount and the steaming time are separately adjusted to solve the deficiencies of the above-mentioned prior art.

Those skilled in the art can understand various changes that can be made according to the present embodiment without departing from the spirit of the present invention. Therefore, it is obvious that the implementations listed are not intended to limit the present invention, but are intended to cover modifications made in the spirit and scope of the present invention, as defined by the scope of the appended claims.
