Description

Technical Field

[0001] This utility model relates to the field of eyeglass manufacturing equipment technology, and more specifically, it relates to a downward bending mechanism for eyeglass temples. Background Technology

[0002] Eyeglasses are lenses encased in a frame and worn in front of the eyes to improve vision, protect the eyes, or for decorative purposes. Eyeglasses generally consist of lenses, a frame, and temples. To prevent glasses from falling off and to make them more comfortable to wear, the temple blanks need to be bent. This involves bending one end of the temple downwards at a certain angle to hook onto the ear and ensure a secure fit. Currently, the bending of temples is generally done manually, which is not only time-consuming and labor-intensive with low production efficiency, but also results in inaccurate bending dimensions. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a downward bending mechanism for the temples of eyeglasses.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A downward bending mechanism for the temple of an eyeglass includes a clamp for holding one end of the temple and a downward bending device for bending the other end of the temple downward; the downward bending device includes a mounting frame, a downward bending assembly, a support arm rotatably mounted on the mounting frame at one end, and a torsion drive assembly for driving the support arm to rotate. The downward bending assembly includes a swing arm rotatably mounted on a support arm at its lower end, an upper bending wheel, a lower bending wheel rotatably mounted on the support arm, and a downward bending drive assembly that drives the swing arm to swing. The upper bending wheel is rotatably mounted on the swing arm and positioned above the lower bending wheel, and can cooperate with the lower bending wheel to clamp the end of the temple to be bent downwards; when the downward bending drive assembly drives the swing arm to swing downwards, the upper bending wheel will cooperate with the lower bending wheel to bend the temple downwards; the twisting drive assembly drives the support arm to rotate the lower bending assembly outwards, twisting the end of the temple to be bent inwards.

[0005] The present invention further comprises: the upper bending wheel is slidably mounted on the swing arm via a slider, and the slider is provided with a driving cylinder for driving the slider to slide. The driving cylinder causes the upper bending wheel to move toward or away from the lower bending wheel by driving the slider to slide.

[0006] The present invention further includes: the downward bending drive assembly includes a downward bending drive motor fixed on the mounting bracket, a first transmission assembly and a second transmission assembly, wherein the downward bending drive motor drives the second transmission assembly to swing the swing arm through the first transmission assembly.

[0007] The present invention further comprises: the first transmission assembly including a downward bending drive sprocket, a downward bending driven sprocket and a first transmission chain connected to the output shaft of the downward bending drive motor, wherein the downward bending drive sprocket is linked with the downward bending driven sprocket through the first transmission chain.

[0008] The present invention further comprises: the second transmission component including a driving shaft, a driven shaft, and a second transmission chain, wherein one end of the driven shaft is connected to the swing arm, and the other end is linked to the driving shaft through the second transmission chain.

[0009] The present invention further comprises: a driven bevel gear connected to the end of the driving shaft, and a driving bevel gear that cooperates with the driven bevel gear connected to the downward-curved driven sprocket; the first transmission component drives the second transmission component to rotate through the cooperation of the driving bevel gear and the driven bevel gear.

[0010] The present invention further comprises: the torsion drive assembly including a torsion drive motor, a torsion drive sprocket, and a torsion driven sprocket fixedly mounted on the mounting frame; the torsion driven sprocket is rotatably mounted on the mounting frame and connected to the support arm. The torsion drive sprocket is connected to the output shaft of the torsion drive motor, and is linked with the torsion driven sprocket through the torsion drive chain, driving the support arm to swing the downward bending assembly outward.

[0011] The beneficial effects of this utility model are as follows: One end of the temple of the glasses is clamped onto a clamp, and the other end is placed between an upper bending wheel and a lower bending wheel. After the upper and lower bending wheels cooperate to clamp the end of the temple to be bent, the lower bending drive assembly drives the swing arm to swing downward. During this process, the swing arm drives the upper bending wheel to roll downward around the edge of the lower bending wheel, bending the end of the temple downward to form a bent part for hooking the ear. In order for this bent part to hook the ear more firmly, after the bending is completed, the twisting... The drive assembly drives the support arm to swing the downward bending assembly outward, causing the downward bending assembly to twist the bent part of the temple inward. This allows the bent part of the temple to clamp the wearer's head inward, making the glasses more secure and preventing them from falling off. By bending the temple downward to form the bent part and twisting the bent part inward through this downward bending mechanism, automated production is achieved. This replaces manual operation, improves production efficiency, and ensures the degree of bending of the temple, thereby increasing the product qualification rate. Attached Figure Description

[0013] See attached document Figures 1 to 4 The present invention provides a more detailed description of an embodiment of a downward bending mechanism for the temples of eyeglasses.

[0014] A downward bending mechanism for eyeglass temples includes a clamp 1 for clamping one end of the temple and a downward bending device 2 for bending the other end of the temple downward; the downward bending device 2 includes a mounting frame 21, a downward bending assembly 24, a support arm 22 rotatably mounted on the mounting frame 21 at one end, and a torsion drive assembly 23 for driving the support arm 22 to rotate; the downward bending assembly 24 includes a swing arm 241 rotatably mounted on the support arm 22 at its lower end, an upper bending wheel 243, a lower bending wheel 242 rotatably mounted on the support arm 22, and a downward bending drive assembly 244 for driving the swing arm 241 to swing. The upper bending wheel 243 is rotatably mounted on the swing arm 241 and positioned above the lower bending wheel 242, and can cooperate with the lower bending wheel 242 to clamp the end of the temple to be bent downwards; when the downward bending drive assembly 244 drives the swing arm 241 to swing downwards, the upper bending wheel 243 will cooperate with the lower bending wheel 242 to bend the temple downwards; the twisting drive assembly 23 drives the support arm 22 to rotate the downward bending assembly 24 outwards, and twists the end of the temple that is bent downwards inwards.

[0015] In practical applications, the device has two downward bending mechanisms that simultaneously bend both temples of the glasses downwards. First, one end of the temple is clamped onto clamp 1, and the other end is placed between the upper bending wheel 243 and the lower bending wheel 242. After the upper bending wheel 243 and the lower bending wheel 242 clamp the end of the temple to be bent, the downward bending drive assembly 244 drives the swing arm 241 to swing downwards. During this process, the swing arm 241 drives the upper bending wheel 243 to roll downwards around the edge of the lower bending wheel 242, bending the end of the temple downwards to form a bent portion for hooking the ear. This is so that... The bending section can more firmly hook onto the ear. After the bending is completed, the twisting drive component 23 drives the support arm 22 to swing the downward bending component 24 outward, so that the downward bending component 24 twists the bending section of the temple inward. This allows the bending section of the temple to clamp the wearer's head inward, thus making the glasses more secure and preventing them from falling off. By bending the temple downward to form the bending section through this downward bending mechanism and twisting the bending section inward, automated production is achieved. This replaces manual operation, improves production efficiency, and ensures the degree of bending of the temple, thereby improving the product qualification rate.

[0016] The upper bending wheel 243 is slidably mounted on the swing arm 241 via a slider 2411. A drive cylinder 2412 is mounted on the slider 2411 to drive it to slide. The drive cylinder 2412 drives the slider 2411 to slide, causing the upper bending wheel 243 to move towards or away from the lower bending wheel 242. The end of the temple of the eyeglasses to be bent is placed between the lower bending wheel 242 and the upper bending wheel 243. The drive cylinder 2412 drives the slider 2411 to move the upper bending wheel 243 towards the lower bending wheel 242, causing the upper bending wheel 243 to engage with the lower bending wheel 242 and clamp the temple of the eyeglasses. After bending is completed, the drive cylinder 2412 drives the upper bending wheel 243 to move upwards, separating the upper bending wheel 243 from the temple of the eyeglasses, thus removing the temple of the eyeglasses from the lower bending assembly 24.

[0017] The downward bend drive assembly 244 for driving the swing arm 241 includes a downward bend drive motor 2441 fixed on the mounting bracket 21, a first transmission assembly 2442, and a second transmission assembly 2443. The downward bend drive motor 2441 drives the second transmission assembly 2443 to swing the swing arm 241 via the first transmission assembly 2442. The first transmission assembly 2442 includes a downward bend drive sprocket 24421, a downward bend driven sprocket 24422, and a first transmission chain 24423 connected to the output shaft of the downward bend drive motor 2441. The downward bend drive sprocket 24421 is linked to the downward bend driven sprocket 24422 via the first transmission chain 24423. The second transmission assembly 2443 includes a drive shaft 24431 and a driven shaft 24432. The second transmission chain 24433 connects the driven shaft 24432 to the swing arm at one end and to the driving shaft 24431 at the other end via the second transmission chain 24433. A driven bevel gear 244311 is connected to the end of the driving shaft 24431. A driving bevel gear 244221 that engages with the driven bevel gear 244311 is connected to the downward-bent driven sprocket 24422. The first transmission component 2442 drives the second transmission component 2443 to rotate through the engagement of the driving bevel gear 244221 and the driven bevel gear 244311. This causes the swing arm 241 to swing downward to bend the temple of the eyeglasses. After bending, the swing arm 241 swings upward to reset, ready to bend the next temple of the eyeglasses downward.

[0018] The twisting drive assembly 23 includes a twisting drive motor 231, a twisting drive sprocket 232, and a twisting driven sprocket 233, all fixedly mounted on the mounting frame 21. The twisting driven sprocket 233 is rotatably mounted on the mounting frame 21 and connected to the support arm 22. The twisting drive sprocket 232 is connected to the output shaft of the twisting drive motor 231 and is linked to the twisting driven sprocket 233 via a twisting drive chain. This causes the twisting drive motor 231 to drive the support arm 22 to swing the downward bending assembly 24 outward, thereby causing the downward bending assembly 24 to twist the bent portion of the temples inward. This automatically completes the twisting process of the bent portion of the temples.
