[0001] This invention relates to the technical field of eyeglass accessory processing equipment, and in particular to a welding method and welding equipment for eyeglass nose pads. Background Technology

[0002] Eyeglasses are a combination of lenses and frames, used to improve vision, protect the eyes, or for decorative purposes. Eyeglasses can correct various vision problems, including nearsightedness, farsightedness, astigmatism, presbyopia, strabismus, or amblyopia. The frames include nose pads, which are welded together using a stem and a mounting cap.

[0003] In traditional welding equipment, workers clamp the cigarette holder and the mounting cap onto a fixture, and then use a spot welding machine to weld the cigarette holder and the mounting cap together to form the overall structure of the nose pad. This manual joining method has the following drawbacks: it does not use inert gas for protection, the quality of the weld is not high, and it is inefficient and has a low output, making it difficult to meet the needs of large-scale production.

[0068] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0069] This invention provides a welding method for nose pads of eyeglasses, used to weld a cigarette holder to a mounting cap. The cigarette holder is clamped by a cigarette holder clamping device, and the mounting cap is locked by a mounting cap locking device. The mounting cap locking device with the mounting cap is brought close to the cigarette holder, and an inert gas is filled around the cigarette holder and the mounting cap. The cigarette holder is welded to the mounting cap using resistance welding. The inert gas is either argon or helium. The welding method of this invention improves welding quality by adding inert gas protection during welding.

[0070] Please see Figures 1 to 24 This is a welding device for nose pads of eyeglasses, as another embodiment of the present invention. Using the above-described welding method, it is used to weld a cigarette rod to a mounting cap. It includes a worktable 100, a cigarette rod feeding device 200 disposed on the worktable 100 for feeding the cigarette rod, a mounting cap feeding device 300 disposed on the worktable 100 for feeding the mounting cap, a cigarette rod clamping device 400 disposed on the worktable 100 for clamping the cigarette rod, a mounting cap locking device 500 disposed on the worktable 100 for locking the mounting cap, and a mounting cap moving device 600 for moving the mounting cap on the mounting cap locking device 500 and bringing it closer to the cigarette rod clamping device 400. The mounting cap feeding device 300 moves the mounting cap onto the mounting cap locking device 500, and the cigarette rod feeding device 200 moves the cigarette rod onto the cigarette rod clamping device 400. Please refer to [link to relevant documentation]. Figure 2 The smoke rod 001 includes end A and end B, with end B primarily welded to the side wall of the mounting cap 002. Specifically, a smoke rod is fed to the smoke rod clamping device 400 via the smoke rod feeding device 200, where it is clamped. The mounting cap feeding device 300 feeds the mounting cap to the mounting cap locking device 500, where it is locked. Then, the mounting cap moving device 600 moves the mounting cap from the locking device 500 closer to the smoke rod clamping device 400, ensuring a tight fit between the mounting cap and the smoke rod. Finally, the two are welded together, for example, using resistance welding. An inert gas is introduced at the weld between the smoke rod and the mounting cap for protection, isolating most of the air, preventing oxidation, and improving weld quality. Further configuration: The workbench 100 is equipped with two sets of the cigarette rod feeding device 200, the mounting cap feeding device 300, the cigarette rod clamping device 400, the mounting cap locking device 500, and the mounting cap moving device 600, so as to facilitate the simultaneous welding of the two nose pads of the same pair of glasses and improve welding efficiency.

[0071] Please see Figures 4 to 6The tobacco rod feeding device 200 includes a tobacco rod vibrating plate 210 disposed on the workbench 100 for feeding tobacco rods, a material blocking mechanism 220 disposed on the workbench 100 and located at the discharge port of the tobacco rod vibrating plate 210, and a tobacco rod gripping mechanism 230 disposed on the workbench 100 for removing tobacco rods from the tobacco rod vibrating plate 210. The tobacco rod gripping mechanism 230 includes a tobacco rod gripping cylinder 231 and two tobacco rod grippers 232 disposed on the tobacco rod gripping cylinder 231. The tobacco rod gripping cylinder 231 drives the two tobacco rod grippers 232 to move closer or further away from each other. The tobacco rod feeding device 200 of the present invention realizes automatic feeding of tobacco rods through the tobacco rod vibrating plate 210 and the tobacco rod gripping mechanism 230. Specifically, the tobacco rod vibrating plate 210 arranges the tobacco rods in sequence, and then the tobacco rod gripping mechanism 230 grips them. There is no need for manual placement, which realizes the replacement of manual operation and achieves the effect of automated feeding. At the same time, it also reduces labor intensity and improves production efficiency.

[0072] The tobacco rod vibrating plate 210 has a tobacco rod discharge pipe 211, which is used for arranging tobacco rods. The discharge port is located at the end of the tobacco rod discharge pipe 211. The vibration of the tobacco rod vibrating plate 210 causes the tobacco rods to enter the tobacco rod discharge pipe 211 side by side. The material blocking mechanism 220 includes a material blocking base 221 set on the worktable 100, a material blocking cylinder 222 set on the material blocking base 221 with the output end facing upward, and a material blocking block 223 set at the output end of the material blocking cylinder 222. The material-blocking cylinder 222 drives the material-blocking block 223 to move vertically and upward, blocking the outlet of the tobacco rod vibrating plate 210 to prevent the tobacco rod from falling from the tobacco rod discharge pipe 211. When the tobacco rod grabbing mechanism 230 clamps a tobacco rod, the material-blocking cylinder 222 drives the material-blocking block 223 to move downward, and the tobacco rod grabbing mechanism 230 removes a tobacco rod from the tobacco rod discharge pipe 211. After completion, the material-blocking cylinder 222 drives the material-blocking block 223 to move upward again. A first sensing device 224 is also provided on the material-blocking block 223. The first sensing device 224 can cooperate with the tobacco rod grabbing mechanism 230 to grab the tobacco rod. When the first sensing device 224 senses that the material-blocking block 223 has moved downward, the tobacco rod grabbing mechanism 230 removes the tobacco rod from the tobacco rod discharge pipe 211.

Specifically, the first linear module 242 is set in the horizontal direction (i.e., the X-axis), and the first moving seat 244 is driven by the first moving motor 243 to move in the horizontal direction, thereby driving the cigarette rod gripping mechanism 230 to move in the horizontal direction. The second linear module 245 is set in the vertical direction (i.e., the Z-axis), and the second moving seat 247 is driven by the second moving motor 246 to move in the vertical direction, thereby driving the cigarette rod gripping mechanism 230 to move in the vertical direction.

[0075] The tobacco rod rotating mechanism 25 includes a tobacco rod rotating cylinder 251 mounted on the second movable seat 247, a rotating seat 252 mounted on the output end of the tobacco rod rotating cylinder 251 and driven by the tobacco rod rotating cylinder 251, and a tobacco rod gripping mechanism 230 mounted on the rotating seat 252.

The second mounting groove 3392 allows for quick installation using only one bolt. Further details can be found in the following section. Figure 24 The second connecting part 3391 is also embedded with a second adsorption element 3396. Before the bolt is tightened, the mounting cap claw 339 can be pre-placed on the mounting step using the second adsorption element 3396. That is, the second adsorption element 3396 is a magnetic element, and the mounting step can be made of an adsorbable metal material.

The clamping cylinder 460 drives the second clamping seat 450 closer to the first clamping seat 440, so that the second pressing block 452 is close to the first pressing block 442, clamping the cigarette rod. The first mounting plate 441 and the second mounting plate 451 are made of copper bases, and the first pressing block 442 and the second pressing block 452 are made of tungsten steel blocks. An external circuit is connected to the first mounting plate 441 and the second mounting plate 451 to energize and heat the first pressing block 442 and the second pressing block 452. While the first pressing block 442 and the second pressing block 452 are heated, the pipe is welded to the mounting cap. This heated pipe clamping device of the present invention, through the mutually cooperating first pressing block 442 and the second pressing block 452, and by energizing the external circuit of the first mounting plate 441 and the second mounting plate 451 to heat the first pressing block 442 and the second pressing block 452, welds the pipe to the mounting cap while the first pressing block 442 and the second pressing block 452 are heated. This achieves the effect of replacing manual operation, thereby achieving automated feeding, while also reducing labor intensity and improving production efficiency.

[0082] The clamping base 410 includes a first base 411, a displacement platform 412 disposed on the first base 411, and a second base 413 disposed on the displacement platform 412. A lifting cylinder 420 is disposed on the second base 413. The displacement base allows the second base 413 to be adjusted along the X-axis or Y-axis on the horizontal plane, which is used to adapt to the feeding device to deliver the tobacco rod to the designated position.

[0083] A guide device is provided between the second clamp seat 450 and the lifting base 430, that is, a guide rail and a guide block are used to enable the second clamp seat 450 to move in the vertical direction.

[0084] The first pressing block 442 is provided with a limiting groove 4421 for inserting the cigarette rod, and the second pressing block 452 is provided with a limiting step 4521 corresponding to the limiting groove 4421. When the cigarette rod is inserted into the limiting groove 4421, the first pressing block 442 and the second pressing block 452 are close together, and the limiting step 4521 is located on the inner side of the cigarette rod. The first pressing block 442 and the second pressing block 452 can better limit the cigarette rod. The first pressing block 442 is detachably mounted on the first mounting plate 441, and the second pressing block 452 is detachably mounted on the second mounting plate 451. With the detachable first pressing block 442 and second pressing block 452, different sizes of nose pads can be produced by simply replacing the first pressing block 442 and the second pressing block 452, thus accommodating the clamping of different sizes of pipes. For different sizes, the limiting groove 4421 of the first pressing block 442 is different, and the limiting step 4521 of the second pressing block 452 is different. A first positioning groove is provided on the first mounting plate 441. After the first pressing block 442 is embedded in the first positioning groove, it is locked by at least one bolt. Specifically, after the bolt passes through the first pressing block 442, it is threadedly connected to the internal threaded hole in the first positioning groove. The locking method of the second pressing block 452 is the same as that of the first pressing block 442.

[0085] Please see Figure 14 , 20 Up to 22, the cap locking device 500 includes a locking base plate 510, a locking support seat 520 disposed on the locking base plate 510, a clamping rod 530 disposed on the locking support seat 520, a welding seat 540 disposed on and detachably connected to the clamping rod 530, and a locking mechanism 550 for restricting the cap to the welding seat 540; the clamping rod 530 is provided with a first through hole 531 for mounting the welding seat 540, and the clamping rod 530 is also provided with an elastic groove 532 that penetrates the upper and lower end faces and penetrates the first through hole 531, the inner sides of the elastic grooves 532 are close to each other to clamp the welding seat 540 in the first through hole 531. A U-shaped groove is provided above the locking support seat 520, the clamping rod 530 is embedded in the U-shaped groove and locked and fixed by bolts. The mounting cap locking device 500 uses a welding seat 540 to place the mounting cap, and then a locking mechanism 550 to fix the mounting cap. Together with the mounting cap feeding device 300, it realizes the automatic feeding of the mounting cap. Specifically, the mounting cap vibrating plate 310 arranges the mounting caps in sequence, and then the mounting cap moving mechanism 330 grabs them. There is no need for manual placement, which realizes the replacement of manual operation and achieves the effect of automated feeding of mounting caps. At the same time, it also reduces labor intensity and improves production efficiency.

[0086] The locking mechanism 550 includes a locking base 551 disposed on the locking base plate 510, a locking cylinder 552 disposed on the locking base 551, a sliding rod 553 disposed on and slidably connected to the locking support 520, and a locking member 554 disposed on and rotatably connected to the clamp rod 530. One end of the sliding rod 553 is driven by the locking cylinder 552 to slide it in connection with the locking support 520, and the other end of the sliding rod 553 is connected to the lower part of the locking member 554. The locking cylinder 552 drives the sliding rod 553 to move forward, causing the locking member 554 and the clamp rod 530 to rotate, so that the upper part of the locking member 554 approaches the welding seat 540 and presses the mounting cap on the welding seat 540. A further configuration is provided: the locking component 554 includes rotating rods 5541 disposed on both sides of the clamping rod 530, and a locking block 5542 disposed at one end of the two rotating rods 5541 and used to press down the mounting cap. The locking block 5542 is located between the two rotating rods 5541. The two rotating rods 5541 are located on both sides of the clamping rod 530 and are installed by pins. After installation, the middle position of the two rotating rods 5541 is rotatably connected to the clamping rod 530. The lower part of the two rotating rods 5541 is connected to the sliding rod 553, and the rotating rods 5541 are provided with elongated holes. A bolt passes through the elongated holes and connects to the sliding rod 553 to limit the lower part of the rotating rods 5541. The upper locking block 5542 can also be fixedly connected by bolts.

[0087] The welding seat 540 in this embodiment includes a main body 541 and protrusions 542 disposed on the upper and lower end faces of the main body 541 for placing mounting caps. The main body 541 is cuboid in shape, which allows for the positioning of the welding seat 540. Simultaneously, the first through hole 531 is adapted to the main body 541, and both ends are provided with protrusions 542. The two protrusions 542 have the same structure and size. When one end is damaged, the welding seat 540 can be adjusted to a different orientation for direct use. Alternatively, the two protrusions 542 may have different sizes to accommodate two different sizes of mounting caps. This means that one welding seat 540 can accommodate two different sizes of mounting caps, improving the adaptability of the welding seat 540.

[0088] The elastic groove 532 extends through the upper and lower end faces and one side wall, and a cylindrical hole 533 or a square hole is provided away from the side wall. An internal threaded hole is provided on one side of the elastic groove 532, and a countersunk hole is provided on the other side. The bolt passes through the countersunk hole and the elastic groove 532 and is screwed into the internal threaded hole. When it is necessary to fix the welding seat 540, the bolt can be tightened. The bolt can be a quick-release type or a wing bolt. When it is necessary to replace the welding seat 540, the bolt can be loosened.

[0089] Please see Figure 13The cap-mounting device 600 includes a fifth linear module 610 mounted on the worktable 100, a fifth moving motor 620 mounted on the fifth linear module 610, a fifth moving seat 630 mounted on the linear module, and a proximity cylinder 640 mounted on the fifth moving seat 630. The locking base plate 510 is moved by the proximity cylinder 640, and the fifth moving motor 620 drives the fifth moving seat 630 to move along a linear direction via the fifth linear module 610. The cap-mounting device 600 drives the cap-mounting device 500 to move along a linear direction, which is the Y-axis direction. Simultaneously, the proximity cylinder 640 also drives the cap-mounting device 500 to move along the Y-axis direction, primarily to bring the cap on the cap-mounting device 500 as close as possible to the clamping device, ensuring a tight fit between the cigarette rod and the cap. The fifth linear module 610 is mounted on the worktable 100 via several pads.

[0090] Please see Figure 1 A frame 110 is provided below the workbench 100, and casters 120 are provided near the four corners of the lower end of the frame 110. The casters 120 facilitate the quick transfer of the welding equipment.

[0091] The working principle of the welding equipment of this invention is as follows:

[0092] The vibrating disc 210 vibrates the tobacco rods, allowing them to be arranged sequentially in the desired direction on the tobacco rod discharge pipe 211. The baffle cylinder 222 drives the baffle block 223 downwards. Then, the first moving motor 243, in conjunction with the first linear module 242, and the second moving motor 246, in conjunction with the second linear module 245, drive the tobacco rod grippers 232 to approach the tobacco rod discharge pipe 211. The tobacco rod gripping cylinder 231 drives the two tobacco rod grippers 232 to grasp the tobacco rods (before grasping, the tobacco rod rotating cylinder 251 needs to drive the two tobacco rod grippers 232). After the tobacco rod is gripped by the tobacco rod gripper 232, the first moving motor 243, in conjunction with the first linear module 242 and the second moving motor 246, in conjunction with the second linear module 245, drives the tobacco rod gripper 232 to approach the clamping device and place the tobacco rod into the limiting groove 4421 (before placing it into the limiting groove 4421, the tobacco rod is rotated by the tobacco rod rotating cylinder 251 until the tobacco rod can be placed into the limiting groove 4421). The second pressing block 452 approaches the first pressing block 442 under the action of the clamping cylinder 460 to maintain the clamping of the tobacco rod.

[0093] The vibrating plate 310 vibrates the caps, allowing them to be arranged sequentially in the desired direction on the cap discharge pipe 311. The lifting mechanism 320 lifts one cap upwards, detaching it from the discharge pipe 311. Then, the third moving motor 333, in conjunction with the third linear module 332, drives the cap-grabbing cylinder 338 and cap-gripper 339 to approach the lifting mechanism 320 and position them above it. The fourth moving motor 336 drives the cap-grabbing cylinder 338 and cap-gripper 339 downwards towards the caps. The cap-grabbing cylinder 338 drives the two cap-gripper 339 to approach and clamp the caps. The fourth moving motor 336 drives the cap-grabbing cylinder 338 and cap-gripper 339 upwards. The third moving motor 333, in conjunction with the third linear module 332, drives the cap-grabbing cylinder 338 and cap-gripper 339 to approach and clamp the caps. The fourth moving motor 336 drives the cap-grabbing cylinder 338 and cap-gripper 339 upwards. The third moving motor 333, in conjunction with the third linear module 332, drives the cap-grabbing cylinder 338 and cap-gripper 339 to move downwards towards the caps. Line module 332 drives the cap gripping cylinder 338 and cap clamping claw 339 to approach the cap locking device 500 and position them above the cap locking device 500. The fourth moving motor 336 works again, driving the cap gripping cylinder 338 and cap clamping claw 339 to move downwards towards the welding seat 540. The cap gripping cylinder 338 drives the two cap clamping claws 339 away. The first drive motor drives the cap gripping cylinder 338 and cap clamping claw 339 to move upwards. The locking mechanism 550 works, and the locking cylinder 552 pushes the sliding rod 553. Under the action of the lever principle, the clamping rod 530 presses the top of the cap. Finally, the moving mechanism works, and the fifth moving motor 620, in conjunction with the fifth linear module 610, drives the entire cap locking device 500 to approach the cigarette rod clamping device 400.

[0094] While the first mounting plate 441 and the second mounting plate 451 are working, argon (or other inert gas) is filled around the smoke rod and the mounting cap to improve the welding quality;

[0095] After welding is completed, the second pressure block 452 is released directly, and the welded nose pad can fall off by itself or be brought back by the mounting cap locking device 500. A feeding cylinder is set on the second moving plate. The feeding cylinder and the mounting cap gripping cylinder 338 are set side by side. The output end of the feeding cylinder is also equipped with two mounting cap grippers 339 for gripping the mounting cap. While the next mounting cap is being fed, the feeding cylinder can be used to move the nose pad to the designated position.

[0096] The welding method of this invention incorporates inert gas protection during welding, which improves welding quality. Simultaneously, the welding equipment of this invention uses a smoke rod feeding device to deliver a smoke rod to a smoke rod clamping device, which clamps the smoke rod. A cap feeding device delivers a cap to a cap locking device, which locks the cap. A cap moving device then moves the cap from the cap locking device closer to the smoke rod clamping device, ensuring a tight fit between the cap and the smoke rod. Finally, the two are welded together. This achieves automated feeding, replacing manual operation, while also reducing labor intensity and increasing production efficiency. Furthermore, this invention includes replaceable first and second pressure blocks, smoke rod grippers, cap grippers, and welding seats, enabling welding of nose pads of different sizes and specifications, significantly improving the utilization and adaptability of the welding equipment.
