Background
At present, in the field of electronic equipment manufacturing, the surfaces of parts and components made of metal materials are bonded with other parts by glue, so that the requirements on flatness and cleanliness of a bonding surface are high. In a traditional process for bonding a decorative part, a groove is generally formed in the surface of a metal part, chemical treatment is performed in the groove to form an antirust protective layer, and then the decorative part is bonded by filling glue in the groove. Because the viscose effect of rust-resistant protective layer is not good, the decoration drops easily, can lead to a large amount of reworks because of the decoration problem that drops causes.

Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.
At present, in the field of electronic device manufacturing, parts and components made of some metal materials are usually adhered to each other by glue. For example, in the LOGO area of the outer surface of the shell of electronic equipment such as mobile phones and tablet computers, a LOGO mounting groove corresponding to the shape of the product LOGO is usually formed, glue is filled in the mounting groove, and then the decorating part in the shape of the LOGO is pressed into the mounting groove, so that the pasting of the decorating part of the product LOGO can be completed.
Because the glue is adopted for bonding, the requirements on the flatness and the cleanness of the bonding surface are higher. In a traditional process for bonding a decorative part, a groove is generally formed in the surface of a metal part, chemical treatment is performed in the groove to form an antirust protective layer, and then the decorative part is bonded by filling glue in the groove. However, since the adhesive effect of the rust-proof protective layer itself is not good, the decoration directly stuck to the rust-proof protective layer by the adhesive is easily peeled off, which also results in a large amount of reworking due to the problem of peeling off the decoration.
In order to make the decoration member stick to the mounting groove more firmly, in some methods, some physical or chemical methods are used to perform special treatment on the anti-rust protection layer in the mounting groove, for example, the anti-rust protection layer in the mounting groove is removed in a large area by planar laser, so that the decoration member can stick to the body of the metal shell by glue. However, after the mounting groove is processed by using the planar laser, because the width of the laser spot is usually smaller than that of the mounting groove, the rustproof protective layer with a certain width still remained near the edge of the mounting groove is not cleaned, and a break with uneven height is formed between the part of the rustproof protective layer which is not cleaned and the cleaned metal body, so that the distribution of glue in the mounting groove is uneven, and the bonding effect near the edge of the mounting groove is still poor; in addition, because the planar laser large-area antirust protective layer is removed, a lot of dust and dirt which are difficult to be cleaned are collected in the mounting groove, and the firmness of the adhesive can be influenced by the dust and the dirt.
In order to solve the above problems, the inventors have studied and proposed the housing and the method of mounting the garnish to the housing in the embodiment of the present application.
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In this embodiment, the depth of the caulking groove 300 with respect to the garnish mounting base 12 may be 10 to 30 um. It is understood that, in other possible ways, the depth of the glue filling groove 300 relative to the decoration mounting base surface 12 may be arbitrary, the depth of the glue filling groove 300 is related to the laser power used in laser engraving and the time of the laser spot staying on the decoration mounting base surface 12, and the glue filling grooves 300 with different depths can be engraved on the decoration mounting base surface 12 by adjusting the output power and the pulse width of the laser according to requirements.
In this embodiment, the center-to-center distance between two adjacent glue filling grooves 300 may be 60-100 um. It is understood that, in other possible embodiments, the center-to-center distance between adjacent glue-filling grooves 300 may be arbitrary, the center-to-center distance of the glue-filling grooves 300 is related to the stepping distance of the laser in the dot matrix laser engraving, and the adjacent glue-filling grooves 300 with different center-to-center distances can be laser-engraved on the decoration mounting bottom surface 12 by adjusting the distance of each movement of the stepping motor.
