Description

[Technical field]

[0001] The present invention relates to a production process and method for a watch bezel, and in particular to a watch ceramic bezel that will not affect the function of a smart watch communication antenna, and a production process and method thereof. [Background technology]

[0002] At present, smart watches are becoming more and more popular due to their strong functionality and convenient and quick use. Among them, smart watches with metal bezels are beautiful overall and highly ornamental when worn, which are sought after by many users of smart watches. However, the metal bezel is made of metal, which will interfere with the signal transmission and reception of the smart watch communication antenna, making the signal of the smart watch unstable and the signal strength low, which is easy to affect the normal use of the smart watch and thus affect the user experience; moreover, the current metal bezel is directly processed on the bezel blank, which cannot effectively prevent the metal bezel from being deformed or the processing effect is not ideal during the processing, thus affecting the yield and quality of the metal bezel. [Summary of the invention]

[0003] The purpose of the present invention is to solve the above-mentioned problems existing in the current smart watches with metal bezels, and to provide a watch ceramic bezel and a production process and method thereof.

[0004] The present invention is achieved through the following technical solutions: a ceramic watch bezel, comprising a bezel, the bezel is in a circular ring shape, and four decorative grooves are arranged on the outer side wall of the bezel.

[0005] Furthermore, the bezel is a ceramic bezel.

[0006] Furthermore, the inner and outer inclined surfaces of the circumference of the bezel are vertically brushed, and the inner and outer inclined surfaces of the circumference of the bezel are high-gloss C-angle surfaces.

[0007] Furthermore, the surfaces of the decorative grooves are all sandblasted.

[0008] A production process and method for a ceramic watch bezel, the specific steps are as follows:

[0009] S1. Prepare a bezel mold, inject bezel material into the bezel mold, degrease the bezel material, sinter the bezel material twice after degreasing, form a ceramic bezel blank with four decorative grooves, and inspect the ceramic bezel blank;

[0010] S2. The ceramic bezel blank is inspected and qualified, and a sub-blade mold is prepared. The ceramic bezel blank is placed in the sub-blade mold, and the sub-blade material is injected into the sub-blade mold. The sub-blade material is degreased. After degreasing, the sub-blade material is sintered twice. The sub-blade material forms a ceramic sub-blade in the inner ring and four decorative grooves of the ceramic bezel blank. The ceramic sub-blade is joined to the ceramic bezel blank to form a ceramic bezel blank with the sub-blade, and the ceramic bezel blank with the sub-blade is inspected;

[0011] S3. The ceramic bezel blank with the sub-blade is inspected and qualified. The ceramic bezel blank with the sub-blade is ground using an electroplated diamond grinding wheel or abrasive rod. During the grinding process, the ceramic sub-blade structure joined to the inner ring of the ceramic bezel blank supports the inner wall of the ceramic bezel blank to prevent the ceramic bezel blank from deformation. The ceramic sub-blade structure joined to the four decorative grooves plays a supporting role, allowing the sub-blade and the bezel to be ground at the same time. During the grinding process, the grinding wheel or abrasive rod will not sink when passing through the four decorative grooves because there is no support underneath, thereby ensuring the roundness of the bezel.

[0012] S4. After the ceramic bezel blank with the sub-blade is ground, the sub-blade structure thereon is knocked off and removed. After the sub-blade structure is removed, the four decorative grooves are sandblasted to obtain a finished ceramic bezel.

[0013] Furthermore, the ceramic sub-embroidery in S2 includes a bezel support body and a decorative groove filling block, wherein the bezel support body is in the shape of a round cake and is located in the inner circle of the bezel, wherein the outer wall of the bezel support body is engaged with the inner wall of the bezel, wherein the bezel support body supports the inner wall of the bezel, wherein the bezel support body prevents the bezel from deforming during processing, and decorative groove filling blocks are provided in each of the four decorative grooves, wherein the top height of the decorative groove filling blocks is not lower than the height of the outer surface of the bezel, and wherein the decorative groove filling blocks prevent the bezel from deforming during grinding processing.

[0014] Furthermore, the bezel support body is provided with a plurality of hollow structures for facilitating the removal of the bezel support body after the bezel is processed.

[0015] The beneficial effects of the present invention are as follows: ceramic is used as the material of the bezel, and there will be no negative effect of the bezel on the communication antenna, and will not affect the normal use and user experience of the smart watch; the inner and outer bevels of the circumference of the bezel are vertically brushed, and the inner and outer bevels of the circumference of the bezel are high-gloss C-angle surfaces, so that the bezel presents a metallic texture and meets the needs of users; four decorative grooves are arranged on the bezel, which can effectively highlight the metallic texture of the bezel, increase the aesthetic coordination of the bezel, and give the user a better sense; the production process and method are mature and stable, and through the addition of the sub-embryo, the bezel will not be deformed during the production process, thereby improving the yield and quality of the ceramic bezel.
