Description

Technical Field

[0001] The present invention relates to the field of glasses, and more particularly to a glasses leg bending mechanism. Background Art

[0002] Glasses are lenses embedded in a frame and worn in front of the eyes to improve vision, protect the eyes or for decorative purposes. Glasses can correct a variety of vision problems, including myopia, hyperopia, astigmatism, presbyopia or strabismus. Glasses are generally composed of lenses, frames and temples.

[0003] In order to prevent the glasses from falling off and to ensure comfortable wearing during use, the glasses leg blank needs to be bent, wherein one end of the glasses leg is bent downward at a certain angle so that the glasses leg can hook the ear, and at the same time, the two glasses legs are required to be bent inward relative to each other so that the glasses leg has appropriate fastening force. However, manual bending is not only time-consuming and labor-intensive, but also easily leads to inaccurate bending dimensions. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention aims to provide a spectacles temple bending mechanism.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0007] The connecting part track and the clamping part track are both arranged perpendicularly to the supporting seat track, the connecting part bending seat is provided with a connecting part bending wheel, and the clamping part bending seat is provided with a clamping part bending wheel;

[0008] When the support seat driver pushes the support seat along the support seat rail to press the glasses leg, the bending drive device will drive the connecting part bending seat or the clamping part bending seat to move, thereby driving the connecting part bending wheel or the clamping part bending wheel to press the glasses leg for bending.

[0009] The present invention further provides that: the bending drive device includes a bending motor, a large gear, a connecting portion rack arranged on the connecting portion bending seat, and a clamping portion rack arranged on the clamping portion bending seat, and the output shaft of the bending motor is provided with a small gear meshing with the large gear;

[0010] The large gear is placed between the connecting portion rack and the clamping portion rack and can mesh with the connecting portion rack and the clamping portion rack.

[0011] The present invention is further provided that: the bending drive device also includes a linkage drive and a linkage shaft, and linkage holes and mounting holes for installing the linkage shaft are respectively arranged at corresponding positions of the bending seat of the clamping part and the rack of the clamping part, and the linkage drive can drive the linkage shaft to pass through the mounting hole and be placed in the linkage hole, thereby fixing the bending seat of the clamping part and the rack of the clamping part.

[0012] The present invention further provides that: the bending drive device also includes a meshing track and a meshing driver, and the meshing driver drives the connecting portion rack to move along the meshing track so that the connecting portion rack is meshed with the large gear.

[0013] The present invention further provides that: a connection part driver for driving the connection part bending wheel to approach or move away from the eyeglass leg is also provided on the connection part bending seat, and the connection part driver can drive the connection part bending wheel to move toward the eyeglass leg and conflict with it.

[0014] The present invention is further provided that: the downward bending device includes a downward bending wheel and a downward bending bracket fixed on a support seat, the large gear is rotatably set on the downward bending bracket, the downward bending wheel is set on the large gear through an angle adjustment component, the angle adjustment component includes an adjustment seat, an adjustment block and an adjustment driver fixed on the adjustment seat; the downward bending wheel is installed on the adjustment block through a rotating shaft; the adjustment seat is fixed on the surface of the large gear, and the adjustment block is slidably set on the adjustment seat; the adjustment driver can drive the adjustment block to move radially along the surface of the large gear, thereby driving the bending wheel to move.

[0015] The present invention further provides that: the adjusting seat is provided with an adjusting track for the adjusting block to move, and the adjusting track is arranged along the radial direction of the surface of the large gear.

[0016] The beneficial effect of the present invention is as follows: after the temple of the glasses completes the downward bending action through the downward bending device, the support seat driver will push the support seat to move along the support seat track towards the temple of the glasses, so that the clamping part bending wheel presses the clamping part of the temple of the glasses. At the same time, the bending drive device will drive the clamping part bending seat to move along the clamping part track, which will drive the clamping part bending wheel set on the clamping part bending seat to press the clamping part of the temple of the glasses to bend. After the clamping part bending wheel hits the temple of the glasses, the clamping part bending wheel bends the clamping part of the temple of the glasses inwardly under the joint action of the support seat driver and the bending drive device, so that the bending angle can be greatly improved, meeting the bending angle requirement of the clamping part of the temple of the glasses, avoiding the insufficient inward bending angle of the clamping part of the temple of the glasses, and failing to clamp firmly for wearing.

[0017] After the bending action of the clamping part of the temple of the eyeglasses is completed, the clamping part bending seat and the supporting seat can be reset, and then the supporting seat driver will push the supporting seat to move along the supporting seat track towards the temple of the eyeglasses, so that the connecting part bending wheel presses the connecting part of the temple of the eyeglasses. At the same time, the bending driving device will drive the connecting part bending seat to move along the connecting part track, which will drive the connecting part bending wheel arranged on the connecting part bending seat to press the connecting part of the temple of the eyeglasses to bend. After the connecting part bending wheel hits the temple of the eyeglasses, the connecting part bending wheel bends the connecting part of the temple of the eyeglasses inwardly under the joint action of the first driver and the bending driving device, so that the connecting part of the temple of the eyeglasses is bent to form an arc that matches the cheek, avoiding the connecting part bending wheel vertically pressing the connecting part of the temple of the eyeglasses, effectively avoiding leaving creases on the temple of the eyeglasses, making the temple of the eyeglasses fit the cheek better when worn, improving the wearing comfort, thereby realizing automatic bending of the temple of the eyeglasses and improving production efficiency.
