## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a connection structure with a workpiece and an object, and more particularly, to a connection structure with an object adhered inside a groove of the workpiece.
2. Description of the Prior Art
Please refer to FIG. 1. FIG. 1 is a diagram illustrating a small object 10 adhered to a workpiece 12 in the prior art. Adhesive 14 is applied to a top surface of the workpiece 12 or a bottom surface of the small object 10, such as a pebble or a jewel, so as to attach the small object 10 to the workpiece 12. However the adhesive 14 applied between the small object 10 and the workpiece 12 always escapes from the interface between the small object 10 and the workpiece 12 so that refinement of feeling is reduced. The small object 10 often departs from the workpiece 12 because the small object 10 can not be attached to the workpiece 12 tightly. In addition, the small object 10 needs to be positioned on the top surface of the workpiece 12 manually and can not be positioned precisely. It causes various and refined arrangement of the small object 10 can not be applied on the workpiece 12. Furthermore, the small object 10 only can be attached on a cloth cover or a leather cover in a hot melt manner so that the application is limited. There is a need to solve the problem of adhering the small object 10 to the workpiece 12 in the prior art.

DETAILED DESCRIPTION
Please refer to FIG. 2 to FIG. 5. FIG. 2 to FIG. 5 are manufacturing diagrams of a connection structure 30 according to a first embodiment of the present invention. The connection structure 30 includes a workpiece 32, and a coating layer 34 disposed above the workpiece 32. The workpiece 32 can be made of metal material, such as a casing of a notebook computer made of magnalium, a casing of a mobile phone, a casing of a watch, a cigarette case, and so on. The coating layer 34 can be spray paint on a surface of the workpiece 32. As shown in FIG. 2, a laser engraving machine 35 engraves the coating layer 34 by laser engraving technique so as to form a groove 36 shown in FIG. 3. A depth of the groove 36 can be adjusted by adjusting output power of the laser engraving machine 35. For example, the depth of the groove 36 can be adjusted to a thickness of the coating layer 34. The laser engraving technique can be controlled by a computer digitally, so after process of the laser engraving technique has a character of precise position. For example, a coordinate location corresponding to the workpiece 32 can be input in the laser engraving machine 35 so as to position the laser engraving location precisely. It can increase variety of a laser engraving pattern or words.
As shown in FIG. 4, after the groove 36 is engraved on the coating layer 34, adhesive 38 can be applied inside the groove 36. Then an object 40 can be installed inside the groove 36 and adhered above the adhesive 38. The object 40 can be a small ornament, such as a pebble or a jewel, or a large object. The object 40 can be installed inside the groove 36 by surface mounting technique for precise position so as to form various patterns on the workpiece 32. Furthermore, the object 40 is wedged and adhered inside the groove 36. The combination of the object 40 and the workpiece 32 is firm, and the groove 36 can contain the run-off adhesive so as to prevent the adhesive 38 from contacting the coating layer 34. In conclusion, the manner of disposing the object 40 to the groove 36 with the adhesive 38 of the present invention includes advantages of precise position, reducing manual cost and error, preventing the run-off adhesive, good adhesion, refinement of feeling, easy process, capability of arranging complicated patterns formed by the objects 40, capability of adhering the object 40 in an irregular shape to the workpiece 32, and so on.
Please refer to FIG. 6. FIG. 6 is a diagram of a connection structure 50 according to a second embodiment of the present invention. The difference between the first embodiment and the second embodiment is that the connection structure 50 includes the workpiece 32 and a groove 52 is formed on a surface of the workpiece 32 directly. The workpiece 32 also can be made of metal material, such as a casing of a notebook computer made of magnalium, a casing of a mobile phone, a casing of a watch, a cigarette case, and so on. The surface of the workpiece 32 can be engraved by laser engraving technique so as to form the groove 52 shown in FIG. 6. A depth of the groove 52 of the workpiece 32 can be adjusted by adjusting output power of the laser. After the groove 52 is engraved on the workpiece 32, the adhesive 38 can be applied inside the groove 52. Then the object 40 can be installed inside the groove 52 and adhered above the adhesive 38. The object 40 can be a small ornament, such as a pebble or a jewel, or a large object. The other principles and advantages of the second embodiment are the same as ones of the first embodiment, and the detailed description is omitted.
In contrast to the prior art, the present invention utilizes after process of laser engraving on mass-produced workpieces without modifying manufacture mold of the workpiece so as to reduce manufacture cost and increase production elasticity. In addition, the manner of disposing the object to the groove with the adhesive of the present invention includes advantages of precise position, reducing manual cost and error, preventing the run-off adhesive, good adhesion, refinement of feeling, easy process, capability of arranging complicated patterns formed by the objects, capability of adhering the object in an irregular shape to the workpiece, and so on. The present invention can combine the crystal pebble or the jewel with the product, such as a notebook computer, a mobile phone, a watch, a cigarette case, and so on. The appearance of the product is refined so as to increase the quality and additional value of the product.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
