Description

Technical Field

[0001] The invention relates to the technical field of glasses manufacturing, and in particular to an automatic bending machine and a bending method for glasses legs. Background Art

[0002] Glasses manufacturing companies are labor-intensive enterprises. With the continuous increase in labor costs and the development of industrial automation, glasses manufacturing has gradually been replaced by automated intelligent mechanical equipment instead of traditional manual production. However, given the particularity of glasses production, it is technically difficult to achieve automation. The current glasses leg bending process: pneumatic initial bending, repeated manual correction of drawings. This process is inefficient, has unstable quality, and high labor intensity. Therefore, equipment that can realize the automation of this process is an urgent need in the market.

[0003] In view of this, the applicant applied for a Chinese invention patent 201811173749.0 on October 9, 2018, which discloses a glasses temple bending machine and a bending method, and applied for another Chinese invention patent 201910694265.9 on July 30, 2019, which discloses an automatic glasses temple bending machine and a bending method. The patent 201910694265.9 includes a machine and a glasses frame positioning mechanism, a glasses lifting device, a glasses temple head clamping device, a glasses temple middle clamping device, a leg tail vertical bending mechanism, a leg tail inner bending mechanism, a leg middle inner bending mechanism, a leg tail vertical bending arc stopper, a leg tail inner bending arc stopper and a leg middle inner bending arc stopper. It also includes a left rotating plate, a left rotating spindle, a left vertical bending motor, a left inner bending motor, a right rotating plate, a right rotating spindle, a right vertical bending motor and a right inner bending motor; the left leg tail vertical bending mechanism, the left leg tail inner bending mechanism and the left leg middle inner bending mechanism are all connected to one end of the left rotating plate, and the other end of the left rotating plate is connected to the left rotating spindle; a left pulley transmission mechanism is provided between the left vertical bending motor and the left rotating spindle, and the left vertical bending motor drives the left rotating spindle to rotate through the left pulley transmission mechanism, so as to drive the left rotating plate to rotate, and then drive the left leg tail vertical bending mechanism to work; a left gear transmission mechanism is provided between the left inner bending motor and the left rotating spindle, and the left inner bending motor The left rotating spindle is driven axially to move through the left gear transmission mechanism, so as to drive the left rotating plate to translate, and then drive the left leg tail inward bending mechanism or the left leg middle inward bending mechanism to work; a right pulley transmission mechanism is provided between the right vertical bending motor and the right rotating spindle, and the right vertical bending motor drives the right rotating spindle to rotate through the right pulley transmission mechanism, so as to drive the right rotating plate to rotate, and then drive the right leg tail vertical bending mechanism to work; a right gear transmission mechanism is provided between the right inward bending motor and the right rotating spindle, and the right inward bending motor drives the right rotating spindle to move axially through the right gear transmission mechanism, so as to drive the right rotating plate to translate, and then drive the right leg tail inward bending mechanism or the right leg middle inward bending mechanism to work.

[0004] Patent 201910694265.9 can perform vertical bending of the tail, inward bending of the tail and inward bending of the middle of the glasses leg through different bending mechanisms, and arc-shaped stopper components are provided for the vertical bending process of the tail, the inward bending process of the tail and the inward bending process of the middle. The curvature of the glasses leg after ordinary bending meets the predetermined requirements. However, since the left leg tail vertical bending mechanism, the left leg tail inward bending mechanism and the left leg middle inward bending mechanism are all connected to one end of the left rotating plate, and the translation and rotation of the left rotating plate are driven by the left rotating spindle, therefore, in the process of bending the glasses leg, the movement range of the left leg tail vertical bending mechanism, the left leg tail inward bending mechanism and the left leg middle inward bending mechanism are all greatly restricted. The specific restriction is that the left rotating plate can only rotate a small angle, and the rotation process will be blocked and restricted by the left leg tail inward bending mechanism and the left leg middle inward bending mechanism, and the left leg tail inward bending mechanism and the left leg middle inward bending mechanism can only push the left leg horizontally. The left eyeglass leg cannot be pushed in a rotating manner. When encountering an eyeglass leg made of highly elastic material, the left leg tail vertical bending mechanism, the left leg tail inner bending mechanism, and the left leg middle inner bending mechanism are all unable to fully bend the eyeglass leg made of such highly elastic material. The reason is that the eyeglass leg made of highly elastic material will rebound partially after bending, and the bending range of the left leg tail vertical bending mechanism, the left leg tail inner bending mechanism, and the left leg middle inner bending mechanism disclosed in Patent 201910694265.9 are all greatly limited, and the eyeglass leg made of highly elastic material cannot be bent to a predetermined curvature. Similarly, the bending range of the right leg tail vertical bending mechanism, the right leg tail inner bending mechanism, and the right leg middle inner bending mechanism disclosed in Patent 201910694265.9 are all greatly limited, and the eyeglass leg made of highly elastic material cannot be bent to a predetermined curvature.

[0024] The beneficial effects of the present invention are as follows: first, the leg-tail vertical bending device of the present invention comprises a left leg-tail vertical bending device and a right leg-tail vertical bending device which are relatively positioned, and the left leg-tail vertical bending device comprises a left vertical bending main shaft, a left main shaft transverse movement mechanism, a left main shaft rotation mechanism and a left vertical bending roller mechanism, and the left vertical bending main shaft is driven to transversely move or rotate through the coordinated driving action of the left main shaft transverse movement mechanism and the left main shaft rotation mechanism, so that the left vertical bending roller mechanism can rotate and swing downward based on the left vertical bending main shaft, and the tail of the left temple of the glasses is vertically pressed and bent onto the left leg-tail vertical bending arc stopper. The bending roller mechanism is driven solely by the left vertical bending spindle, and the amplitude of the left vertical bending spindle's downward rotation and swing can be easily controlled from small to large. Therefore, the ends of the glasses legs made of high, medium and low elastic materials can be vertically bent, and all of them can be vertically bent to a predetermined curvature. Similarly, since the right vertical bending roller mechanism is driven solely by the right vertical bending spindle, the amplitude of the left vertical bending spindle's downward rotation and swing can be easily controlled from small to large. Therefore, the ends of the glasses legs made of high, medium and low elastic materials can be vertically bent, and all of them can be vertically bent to a predetermined curvature. Secondly, the leg-tail inward bending device of the present invention comprises a left leg-tail inward bending device and a right leg-tail inward bending device which are relatively positioned, and the left leg-tail inward bending device comprises a left leg-tail inward bending main shaft, a left inward bending main shaft lifting mechanism, a left inward bending main shaft rotating mechanism and a left leg-tail inward bending rotating column, and the left leg-tail inward bending main shaft is driven to lift or rotate by the coordinated driving action of the left inward bending main shaft lifting mechanism and the left inward bending main shaft rotating mechanism, so that the left leg-tail inward bending rotating column is caused to rotate and swing based on the left leg-tail inward bending main shaft, and the tail of the left leg of the glasses is pressed inward to bend onto the left leg-tail inward bending arc-shaped stopper. The left leg tail inward bending rotating column is driven solely by the left leg tail inward bending spindle, and the amplitude of the rotation and swing of the left leg tail inward bending spindle can be easily controlled from small to large. Therefore, the legs of glasses made of high, medium and low elastic materials can be bent inward at the tail, and all of them can be bent to a predetermined curvature; similarly, since the right leg tail inward bending rotating column is driven solely by the right leg tail inward bending spindle, the amplitude of the rotation and swing of the right leg tail inward bending spindle can be easily controlled from small to large. Therefore, the legs of glasses made of high, medium and low elastic materials can be bent inward at the tail, and all of them can be bent to a predetermined curvature. Third, the leg-middle-inward bending device of the present invention comprises a left-leg-middle-inward bending device and a right-leg-middle-inward bending device which are relatively positioned. The left-leg-middle-inward bending device comprises a left-leg-middle-inward bending rotating column mechanism and a left-leg-middle-inward bending motor. The left-leg-middle-inward bending motor is used to drive the left-leg-middle-inward bending rotating column mechanism to rotate inward, so as to press the middle part of the left temple of the glasses inward onto the left-leg-middle-inward bending arc-shaped stopper. Since the left-leg-middle-inward bending rotating column mechanism is driven solely by the left-leg-middle-inward bending motor, the amplitude of its inward rotation can be easily controlled from small to large, so that the temples of the glasses made of high, medium and low elastic materials can all be bent inward, and all can be bent to a predetermined curvature; similarly, since the right-leg-middle-inward bending rotating column mechanism is driven solely by the right-leg-middle-inward bending motor, the amplitude of its inward rotation can be easily controlled from small to large, so that the temples of the glasses made of high, medium and low elastic materials can all be bent inward, and all can be bent to a predetermined curvature.
