DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The processing method of the eyeglasses frame of the present invention mainly lies in that, the technical process can be adjusted based on existing technologies, namely, the embossed decorative pattern on the eyeglasses frame can be processed mechanically by means of stretching and compressing of the metal wire unit. Give the fact that wire processing can be easily performed by existing mechanical equipments, such as: compressing machine, various embossed patterns can be easily shaped, and the wire gauges at different positions can be adjusted, thereby forming various intended decorative patterns when the eyeglasses frame is shaped.

The processing method of the present invention, as shown in FIG. 1 , comprises the following steps:

S101 : acquire the metal wire unit: said metal wire is a commonly-used raw material for processing the eyeglasses frame by existing technology, which is available with different types for meeting actual demands; the metal wire unit can be acquired by either cutting the wires into predefined length, or processed firstly into preset form and then cut as a processing unit of the processing machine.

S102: process the metal wire unit: a groove 210 can be formed at one side of the wire by means of compressing, etc, as shown in FIGS. 3a-3c; the embossed decorative pattern 220 can be designed to be formed at other side and positions, as shown in FIG. 2. The embossed decorative pattern 220 (i.e. an integrated pattern after eyeglasses frame is formed) can be processed on the wire as per the design; the simple processing technique allows for easy processing of the vertical plane of the metal wire unit, but existing processing technique cannot realize the processing of embossed dents on the eyeglasses frame.

The processing equipment adopted for the present invention refers to a common compressing machine.

S103: fold the processed metal wire unit into an eyeglasses frame. When the metal wire unit is folded, one side with a groove 210 faces inwards for retaining the lens.

S104: finally weld the coupling ends 231 , 232 of the metal wire unit, as shown in FIGS. 4a-4b and FIG. 5; the folded and welded eyeglasses frame is illustrated in FIG. 2, wherein the inner side can be used for assembly of lens. The subsequent processing technique comprises: connection of eyeglasses legs as well as two eyeglasses frames.

According to another preferred embodiment of the processing method of the present invention, the metal wire unit is punched to form different wire gauges and several circular embossed dents with varying gas during the production process described in S102. Various flexible designs are made possible in line with the actual effect and design patterns of the eyeglasses frame. As the processing on wire is easier than that on circular frame, the processing process of the present invention has overcome the shortcoming of existing technology for the metal eyeglasses frame, making it convenient to design and process flexibly the eyeglasses frame with excellent visual effect.

In the processing method of this invention, said S103 also includes: the metal wire unit can be folded according to the size and curvature of the lens, allowing for minor adjustment of the eyeglasses frame after production. Additionally, S104 also includes: cut the welded coupling ends 231 , 232 of the eyeglasses frame, as shown in FIG. 2, and install a screwing mechanism to connect both ends for easy assembly of lens.

The eyeglasses frame of the present invention has no inherent difference with prior art, but the production technology of the present invention could help to process not only various eyeglasses frames of prior art, but also a novel eyeglasses frame of strong 3D sense.

Referring to FIG. 2-an eyeglasses frame of the present invention for retaining the lens, wherein a metal wire unit is folded around the lens, and a groove 210 is arranged at inner side as shown in FIGS. 3a-3c, wherein the metal wire unit is punched and folded to form the eyeglasses frame 200 for adapting the lens; at least an embossed decorative pattern 220 is also set on the eyeglasses frame 200. Preferably, several decorative patterns 220 can be arranged along the molded eyeglasses frame with an unequal spacing, providing the frame with a better 3D impression and textural quality. The embossed decorative pattern can also be processed onto the metal wire by common compressing machine.

As the eyeglasses frame of the present invention is firstly processed on the metal wire, the arrangement around the lens of the eyeglasses frame is very flexible depending on the changing wire gauges, and the embossed decorative pattern can be placed at any sides other than the side with the groove.

For the eyeglasses frame of the present invention, the embossed decorative patterns are implemented on the metal wire or the cut metal wire unit, as shown in FIGS. 4a and 4b as well as FIG. 5. With the introduction of processing technology on the metal wire, the eyeglasses frame of the present invention has variable wire gauge, and circular embossed dents or embossed decorative patterns can be randomly punched, so the eyeglasses frame of the present invention presents excellent 3D sense and decorative attribute, and allows changing flexibly the design as a novel structure.

Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
