In the present invention, because the bearing body of the abrasive carrier body corresponds to the key opening of the keyboard cover body, and is stacked on the keyboard cover body to be ground through the master mold cover, therefore, when the grinding device is in the process of grinding, the It can effectively avoid the problems of falling ridges and crooked ridges, and the ridges of the keyboard openings. It can effectively maintain the integrity of the opening ridges of the key openings of the keyboard and the ridges of the depressed bevels of the keyboard during grinding, and maintain the fineness of the product surface painting. It is mass-produced by the type of jig.

In order to make the above-mentioned features and advantages of the present invention more obvious and easy to understand, the following specific embodiments are given together with the accompanying drawings, and are described in detail as follows.

Please refer to FIGS. 1 , 2 , 3 and 4 at the same time, wherein, FIG. 1 is a schematic diagram of the arrangement relationship of the components of the present invention, and FIG. 2 is a schematic diagram of the abrasive carrier carrier of the present invention supporting the keyboard cover. FIG. 3 is a schematic diagram of FIG. 2 plus a master mask and a grinding apparatus. FIG. 4 is a partial enlarged schematic view of FIG. 3 .

In FIG. 1 , the abrasive carrier 110 , the keyboard cover 120 and the master mold cover 130 are superimposed in such a way that the bottom is the abrasive carrier 110 , and the abrasive carrier 110 is provided with a plurality of bearing The supporting body 111 and the positioning member 112, wherein the number of the supporting body 111 is not limited. It is worth mentioning that the supporting body 111 is mainly designed in the manner of imitating the key cap, protruding from the grinding member supporting body 110, when the keyboard cover body 120 When stacked on the abrasive carrier 110 , the bearing body 111 of the abrasive carrier 110 is protruded from the key opening 121 on the keyboard cover 120 , in order to prevent the abrasive instrument 400 from being affected by the downward pressure channel. Because of the ridgeline of the key opening 121 , the height of the bearing body 111 is slightly lower than the upper surface of the keyboard cover 120 by about 0.2 mm, and the abrasive carrier 110 supports the keyboard cover 120 in the form shown in FIG. 2 . Show.

Next, the master cover 130 is positioned and pressed on the keyboard cover 120 through the positioning member 112 of the abrasive carrier 110 . A slanted surface is formed extending from the inner bottom, and the recess of the keyboard cover 120 surrounds a slanted edge. Therefore, the inclination angle of the slanted surface of the tool of the master mold cover 130 is the same as the slope of the recessed portion of the keyboard cover 120 . It is said that when the master cover 130 is positioned and pressed on the keyboard cover 120, an inclined plane is formed from the depression of the keyboard cover 120 to the bevel of the mold cover 130, so that when the grinding apparatus 400 grinds When the concave portion of the keyboard cover 120 is beveled, the ridgeline of the concave inclined surface of the keyboard of the keyboard cover 120 can be prevented from being slanted (as shown in FIG. 3 and FIG. 4 ).

For this, we solved this problem by making the inclination angle of the bevel of the mold of the master mold cover 130 consistent with the bevel of the depression of the keyboard cover 120. The problem is that when the master cover 130 is positioned and pressed on the keyboard cover 120, the slanted surface of the mold extending from the depression of the keyboard cover 120 to the master cover 130 forms an inclined plane, so that when the grinding apparatus 400 is used, an inclined plane is formed. When grinding the beveled edge of the concave portion of the keyboard cover 120, the ridgeline of the concave inclined surface of the keyboard of the keyboard cover 120 can be prevented from being distorted;

Second, the key openings 121 are prone to collapse due to grinding during grinding. For this point, we design the bearing body 111 of the abrasive carrier 110 by imitating the key caps, so that the abrasives can carry The bearing body 111 of the body 110 is protruded from the key opening 121 on the keyboard cover body 120. When the grinding apparatus 400 is grinding, the grinding element carrier 110 designed in the manner of imitating the key cap will not The downward pressure channel affects the opening ridgeline of the key opening 121 .

To sum up, when the grinding apparatus of the present invention grinds the surface of the keyboard cover after painting, it can effectively avoid the problems of falling ridgelines and crooked ridgelines, and the ridgelines of the keyboard openings are collapsed, and can effectively maintain the openings of the key openings of the keyboard during grinding. The integrity of the ridgeline and the ridgeline of the keyboard concave bevel and the fineness of the paint on the product surface are maintained.
