Description

Technical Field

[0001] The utility model relates to the technical field of glasses production equipment, and more specifically, to an inner bending mechanism for glasses legs. 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 are generally composed of lenses, frames and temples.

[0003] In order to prevent the glasses from falling off and make them more comfortable to wear during use, the glasses foot blank is bent to make them more firmly worn, that is, one end of the glasses foot is bent downward at a certain angle so that the glasses foot can hook the ear and make it firmly worn on the ear; people's faces are not flat, but have a certain amplitude. In order to wear them comfortably, the middle part of the glasses foot needs to be bent to have a certain amplitude to avoid the glasses foot being close to the wearer's face when worn; the existing bending process of the glasses foot is generally performed manually, which is not only time-consuming and labor-intensive, but also has low production efficiency; and there is also the problem of inconsistent bending size.

[0027] See attached Figures 1 to 6 The utility model is further described in detail with respect to an embodiment of the inner bending mechanism of the temple of glasses.

[0028] A mechanism for bending the temple of spectacles inwards, comprising a base 1, one end of which is fixedly provided with a clamp 2 for clamping one end of the temple of spectacles, and the other end of which is provided with an inward bending device 3 for bending the temple of spectacles outwards; the inward bending device 3 comprises a support frame 31 provided with a mounting plate 32, a bending roller 35 and a clamping assembly 34 for clamping the other end of the temple of spectacles;

[0029] The clamping assembly 34 includes a clamping seat 36, a swinging member 3421 rotatably arranged on the clamping seat 36, a first clamping roller 341 and a second clamping roller 342 that cooperate with each other; the first clamping roller 341 is installed on the mounting plate 32, the second clamping roller 342 is connected to the rotating shaft position of the swinging member 3421, the bending roller 35 is arranged on the swinging member 3421 and is placed on one side of the second clamping roller 342; the clamping seat 36 is slidably arranged on the mounting plate 32, and a return spring 361 is arranged at the rear end of the clamping seat 36; one end of the swinging member 3421 is connected to a tension spring 6, and the other end is connected to a clamping and bending drive assembly 5;

[0030] The clamping and bending driving assembly 5 first causes the swinging member 3421 to move toward the rear end along with the clamping seat 36 (after the driving assembly 5 starts to pull the steel wire 51, the resistance of the tension spring 6 is greater than the return spring 361, so that the clamping seat 36 slides backward, thereby driving the second clamping roller 342 to approach the first clamping roller 341, thereby clamping the eyeglass leg. After clamping, the second clamping roller 342 abuts against the eyeglass leg, so that the clamping seat 36 cannot move in the sliding direction, causing the clamping seat 36 to be in a stationary state. At this time, the pulling steel wire 51 The wire 51 continues to pull to overcome the resistance of the tension spring 6, driving the swinging member 3421 to swing around the rotating shaft). During this process, the clamping seat 36 compresses the reset spring 361, so that the second clamping roller 342 moves toward the first clamping roller 341 and clamps the eyeglass leg. As the clamping seat moves backward, the tension of the clamping and bending driving assembly 5 is sufficient to overcome the tension spring 6, and the clamping and bending driving assembly 5 drives the swinging member 3421 to rotate around the rotating shaft, so that the bending roller 35 presses the outer wall of the eyeglass leg inward.

[0031] One end of the temple of the glasses to be bent is clamped on the clamp 2, and the other end is placed on the clamping assembly 34; the clamping and bending driving assembly 5 first moves the swinging piece 3421 backward with the clamping seat, so that the second clamping roller 342 moves toward the side of the first clamping roller 341, and cooperates with the first clamping roller 341 to clamp the temple of the glasses to be bent; the clamping and bending driving assembly 5 continues to drive, driving the swing arm to rotate around the rotating shaft, so that the bending roller 35 rotates with the swinging piece 3421, squeezing the outer wall of the temple of the glasses inward, so that the temple of the glasses is bent and deformed inwardly with a certain arc; the temple of the glasses is more suitable for the wearer's face shape, avoiding the temple of the glasses from sticking to the wearer's face, and improving the comfort of wearing glasses; the inward bending mechanism replaces the traditional manual bending operation, improves production efficiency, and at the same time improves the accuracy of the bending range to ensure the qualified rate of products.

[0032] The clamping and bending drive assembly 5 includes a clamping and bending drive motor 52 and a traction wire 51, one end of the traction wire 51 is connected to the swing member 3421, and the other end is connected to the clamping and bending drive motor 52; the clamping and bending drive motor 52 drives the swing member 3421 by pulling the traction wire 51 outward.

[0033] The mounting plate 32 is slidably arranged on the support frame 31; a rack 311 is arranged on the support frame 31, and a first driving motor 33 is fixedly installed below the mounting plate 32, and a gear 331 matching with the rack 311 is arranged on the output shaft of the first driving motor 33, and the rack 311 is in an arc shape protruding outward; the first driving motor 33 drives the mounting plate 32 to slide through the gear 331 matching with the rack 311; when the mounting plate 32 slides along the arc track of the rack 311, the bending roller 35 squeezes the legs of the glasses at multiple points, so that the legs of the glasses have a better bending effect.

[0034] The support frame 31 is slidably arranged on the base 1, and a close driving assembly 4 for driving the support frame 31 to slide is provided on the base 1; the close driving assembly 4 includes a sliding second driving motor 41 and a driving screw 42, one end of the driving screw 42 is connected to the output shaft of the second driving motor 41, and the other end is threadedly connected to a screw sleeve 43 connected to one side of the support frame 31; the second driving motor 41 drives the support frame 31 to slide on the base 1, so that the first clamping roller 341 is close to the outer wall of the eyeglass leg, eliminating the gap between the first clamping roller 341 and the outer wall of the eyeglass leg, so as to better cooperate with the second clamping roller 342 to tightly clamp the eyeglass leg to be bent;

[0035] The base 1 is provided with a track 11 , and the bottom of the support frame 31 is slidably disposed on the track 11 via a slider 312 , so that the support frame 31 can slide on the base 1 more stably.
