Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for correctly bonding a nose pad to a spectacle frame manufactured by carving a large plate material, and a spectacle frame to which the nose pad is bonded.

[0002]

2. Description of the Related Art A spectacle frame that is injection-molded can be partially formed not only in its outer shape but also in thickness, so that a nose pad can be simultaneously molded with the frame. However, the eyeglass frame made of resin is not limited to the frame formed by injection molding, and may be manufactured by cutting out a plate material having a certain thickness. That is, it is called a cut-out frame. Injection molded frames are extremely low in production cost, but are limited to plain and monotonous colors.However, frames that are carved out are a variety of frames with patterns. Preferred.

[0003] However, in the frame to be cut out,
Since the material is a plate having a certain thickness, it is extremely costly to cut out a nose pad formed to protrude to the back side of the frame from the same plate. Therefore, conventionally, a nose pad made by separately punching a plate material is adhered to a predetermined position, and an excess portion is cut off later.

FIG. 4 shows a conventional nose pad manufacturing process, in which a plate material is heated and punched into a roughly heart shape, heated and bent into a predetermined shape, and further separated into two pieces.
The separated nose pad will be adhered to the predetermined position of the frame, but it will be misaligned because it is a manual operation,
Therefore, a large nose pad is manufactured in advance, and this is scraped off after bonding. For this reason, the number of man-hours required for mounting the nose pad is extremely high.

[0005]

As described above, the mounting of the conventional nose pad has the above-mentioned problems. The problem to be solved by the present invention is this problem. It is an object of the present invention to provide a method of bonding a nose pad and a spectacle frame that can easily manufacture a nose pad and properly bond the nose pad. .

[0006]

The eyeglass frame of the present invention is intended to be manufactured by cutting a plate material, and a nose pad which is separately manufactured is bonded to the cut frame. The nose pad is formed in a predetermined shape in advance so that it is not necessary to scrape off the nose pad as in the related art. In the present invention, the specific shape of the nose pad is not limited, and a nose pad suitable for an eyeglass frame is formed and adhered to a predetermined position.

In the prior art, an extra portion was scraped off and then processed into a predetermined shape after bonding. However, in the present invention, processing after bonding is basically eliminated. It is necessary to adhere and not displace. Therefore, in the present invention, a bonding device or a bonding jig is used instead of a worker manually bonding. The front frame is fixed at a fixed position. In this state, the nose pad is picked up, an adhesive is applied, and the front frame is adhered to the fixed position. Here, the specific structures of the frame fixing device and the nose pad pad picking and bonding jig are not limited.
Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0008]

FIG. 1 shows an embodiment in which a nose pad is adhered to a front frame of glasses. In the figure, reference numeral 1 denotes a rim formed on a front frame, and 2 denotes a nose pad. The front frame is manufactured by cutting a plate material having a constant thickness. As a method of shaving, the outer shape and lens hole of the front frame are cut with an end mill or a drill, and then the surface is polished. Of course,
The specific process is optional, and another work process may be added.

[0009] The front frame manufactured by cutting out a plate material as described above has a pattern, is colorful, and is superior in appearance in comparison with an injection molded frame. FIG. 2 shows the formed nose pad. The nose pad has a shape capable of supporting the front frame on the nose, and its surface 3 is smoothly curved to fit the nose.

The specific shape of the nose pad is not limited, and a nose pad suitable for the front frame is used.
The nose pad is bonded to a predetermined position on the front frame by using an adhesive jig that can be sucked by air. FIG. 3 is a specific example showing a jig for bonding the nose pads, and the bonding jigs 4a and 4b form a pair so that the two nose pads 2 and 2 can be simultaneously bonded.

The bonding jig 4 comprises a suction tool 5 and a shaft 6,
A suction tool 5 is provided at the lower end of the shaft, and a nose pad is fitted into a concave groove formed below the suction tool 5 and sucked by air. The air is sucked through the shaft 6 and rotates and moves up and down. Then, the nose pad put in the concave groove of the suction tool 5 is bonded to the front frame fixed at a predetermined position by moving the bonding jigs 4a and 4b. The adhesive may be applied to the front frame side, or may be applied to the nose pad.

On the other hand, in the operation of shaving the front frame, a recess may be formed at a predetermined position, and a nose pad formed in the recess may be fitted. Here, the nose pad is formed with a convex portion that fits into the concave portion. In this case, the nose pad can be correctly adhered to a predetermined position without using the above-mentioned bonding jig. As described above, the eyeglass frame of the present invention is obtained by bonding the formed nose pad to a predetermined position, and can obtain the following effects.

[0013]

The eyeglass frame according to the present invention is obtained by molding a nose pad into a predetermined shape and bonding the nose pad to a predetermined position on the front frame. No need to scrape. Therefore, the number of man-hours is greatly reduced as compared with the conventional nose pad bonding, and the cost is reduced without lowering the quality. Then, the nose pad can be properly adhered to a predetermined position of the front frame by using a special jig, so that it is not necessary to rework the nose pad later. When no bonding jig is used, an uneven portion for positioning can be formed.
