Description

The thin plate frame a section hair-line grinding machine equipment inside of phone case frame}

The present invention relates to a polishing apparatus for hair line (Hair Line) processing on a portion of the surface of the metal thin plate frame embedded in the mobile phone case.

In general, a metal thin frame frame is formed by pressing, bending, or the like to support or firmly fix various elements inside the slide mobile phone, which is raised and lowered up and down.

Part of the surface of the back of the thin metal frame is exposed to the outside during the up and down slide operation of the mobile phone, and has excellent aesthetic hairline treatment (one for the surface finish that rubs sandpaper of ultrafine particles to form a beautiful grain) Polishing method) in many cases.

However, to treat the hairline on part of the backside (exposed and exposed) of the metal frame,

Initially, a method of forming (pressing and bending) a metal thin frame using a material having a hairline surface treatment on the entire surface of the metal thin plate (using a hairline-treated raw material) was used.

This is not only a large economic burden due to the purchase of raw materials, but also a loss rate of the material, and a hairline that has been processed in the process of making a frame through a process such as pressing and bending has a problem of impairing the merchandise.

Therefore, in recent years, it is usual to proceed to the post-processing method of first processing the frame with a general metal sheet without hairline treatment, and then processing the hairline through an additional separate hairline polishing process on one side of the frame. have.

However, the hairline treatment through post-processing does not have any problem when the shape of the entire surface of the frame requiring hairline processing is a smooth condition for polishing, but it is not,

Convex portions (various embossing or burring, etc., which may be protruded as necessary for fixing or seating the various parts to be mounted) protrude in some sections except the smooth surface of the entire area of one side of the frame (i.e., In some cases, a part of the total area of one side that requires hairline processing has a smooth flat section, while the other part is a frame having a convex section formed with a plurality of convex portions). There was a problem.

In other words, the conventional polishing operation for the hairline treatment is simply a form of processing through the horizontal movement of the polishing belt appearing in the lower swing section during the swinging movement of the polishing belt wound between a plurality of winding rollers and its friction,

If the overall condition of the surface to be processed that requires hairline treatment is not horizontal or at least a smooth condition without protrusions is created,

The hairline machining process itself is virtually impossible, and there is a considerable problem that it is inevitable to give up the hairline and select or omit other surface treatment methods.

Therefore, in the present invention, a part of the total area of one side using the polishing belt to rotate continuously, but some sections have a flat surface portion, while other parts of the polishing belt for the hairline post-processing the frame having a convex portion formed with a plurality of convex portions Some of the horizontal motion completely escapes the convex portion, while the other part frictionally counteracts the flat portion, thereby allowing partial hair of the thin frame frame embedded in the new slide mobile phone to allow selective hairline work on only the horizontal portions exposed to the outside. The main object of the present invention is to provide a line polishing device, and thus, the technical problem is completed.

The present invention for achieving the above technical problem is that the polishing belt 105 is wound around the left and right after each fixed installation of the polishing belt guide rollers 102, 103 to maintain a constant distance from each other; The upper surface portion of the polishing belt 105, which is held tightly between the polishing belt guide rollers 102 and 103, supports the horizontal support of the polishing belt 105 during polishing to apply a horizontal friction and a constant frictional force. The unit 20 is installed; The frame support corresponding device 30 is provided on the lower side of the polishing belt 105 corresponding to the polishing support unit 20.

As described above, the mobile phone case frame polishing machine is configured to selectively fix only the hairline (polishing work) work area of a specific part of the mobile phone frame by using the polishing support unit 20 to be fixed at an arbitrary position. The position is lowered downward by a fixed distance A at which the processing part evacuation angle C can be formed and fixed to be stepped while moving to the guide plate 201 of the polishing support unit 20 while polishing the frame M. There is an effect that can selectively exclude the parts that do not need, it is possible to continuously work at high speed, the expectation is indeed a great invention.
