Abstract
Description
The present invention relates to a jig device for polishing a terminal case.
The terminal is provided with a case for the protection of the internal device and the safety of the user.
The inner surface of the terminal case faces the various electronic devices constituting the terminal, and the outer surface of the terminal case faces the external environment.
The process of manufacturing such a terminal case may include a step of smoothly grinding the surface of the case or peeling off the paint which is mistakenly painted on the case.
Korean Patent Registration No. 1342793 discloses a process for manufacturing a metallic casing for mobile phones, but does not mention a method for polishing the casing of the casing.
The present invention is to provide a jig device for smoothly polishing the surface of a terminal case or polishing colored paint on a terminal case.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not intended to limit the invention to the precise forms disclosed. Other objects, which will be apparent to those skilled in the art, It will be possible.
A jig device of the present invention includes: a sanding unit for moving a moving member along a first direction and a second direction orthogonal to each other; And a support unit disposed at a position facing the moving member and moving relative to the sanding unit along a third direction orthogonal to the first direction and the second direction, The terminal case is supported on one of them and the polishing part for polishing the terminal case can be supported on the other.
A jig device of the present invention includes: a sanding unit for moving a moving member along a first direction and a second direction orthogonal to each other; And a supporting unit disposed at a position facing the moving member and moving along a third direction orthogonal to the first direction and the second direction, wherein the terminal case is detachably attached to the supporting unit, The unit may be equipped with a polishing part for polishing the paint applied to the side surface of the terminal case.
The jig device of the present invention can move one of the polishing unit and the terminal case in the first direction and the second direction and move the other in the third direction of the terminal through the sanding unit and the supporting unit. According to this, the surface to be processed in the terminal case can be polished by the polishing portion. Whereby the surface of the terminal case can be obtained in which the surface is smoothly polished or the paint is effectively peeled off.
Particularly, when the rotary unit in which the terminal case rotates is provided, a plurality of processing surfaces can be successively polished in the terminal case. According to this, the side surface of the terminal case, which needs to be continuously polished, can be automatically polished.
The terminal case having a surface smoothly processed by the jig device of the present invention can enter the paint painting process. Alternatively, the terminal case in which the paint has been peeled off by the jig device of the present invention can enter the process of redrawing the paint.
