With increasing awareness of vision protection and the influence of fashion trends, glasses have evolved from simply a tool for vision correction to a product that combines practicality and decorative features. Consequently, market demand for eyewear continues to grow, and so too do the demands for frame quality and design. Welding is a critical process in the production of metal frames. Traditionally, welding frames is largely manual, relying primarily on handheld welding tools to weld the various frame components. This method is not only inefficient but also requires high worker skill. Welding quality can easily vary due to human factors, making it difficult to ensure product consistency and stability.

[0023] It should be noted that the top plate 93 and the bottom plate 90 are arranged in parallel and are both fixed to the two ends of the two limiting columns 92 to ensure the stability of the limiting columns 92.

[0024] In the present invention, preferably, the spacing adjustment mechanism 8 includes a motor 80 fixed to the bottom of the top plate 93; Connecting rod 1 81 is fixedly connected to the output end of motor 1 80 and one end of which is fixedly connected to motor 2 82; The second screw rod 84 is fixed to the output end of the second motor 82 and has a sliding block 83 threadedly connected to its surface; One end of the connecting rod 2 85 is hinged to the surface of the sliding plate 1 94 and the other end is hinged to one side of the sliding block 83.

[0031] It should be noted that both ends of the limiting block 1 31 and the limiting block 2 34 are fixedly connected with clamping columns, and the clamping material is rubber material to avoid damage to the metal eyeglass frame when limiting.

[0032] In the present invention, preferably, a support block 4 is fixedly connected to the middle part of one side of the welding table 1, a threaded column 11 is rotatably connected to the middle part of the support block 4, and a connecting rod 12 that slides in the slide groove of the support block 4 is threadedly connected to the surface, and one end of the connecting rod 12 is connected to an angle adjustment mechanism 5 to achieve angle adjustment of the welding gun body 7, and a compensation mechanism 6 is connected to one side of the angle adjustment mechanism 5 to achieve telescopic compensation of the welding gun body 7.

[0033] In the present invention, preferably, the angle adjustment mechanism 5 includes a docking block 50 fixed to one end of the connecting rod 12; Steel ball 51, movably mounted in docking block 50; A bidirectional screw rod 53 rotates on one side of the docking block 50 and has two symmetrically arranged sliding plates 54 threadedly connected to its surface; The clamping plate 52 is fixed to one end of the sliding plate 54 .

[0034] It should be noted that there is a space inside the docking block 50 for the steel ball 51 to move, and the steel ball 51 cannot be separated; The surface of the bidirectional screw rod 53 is provided with two sets of symmetrically arranged thread groups, and the two sets of thread groups are threadedly connected to the sliding plates 54, so that the two sets of sliding plates 54 can move relative to the clamping plate 52; The clamping plate 52 is made of rubber material, which makes the friction of the clamping plate 52 larger and can effectively prevent the steel ball 51 from rotating; The interior of the docking block 50 is provided with a moving space for the sliding plate 54 and the clamping plate 52 to avoid interference, and the moving space is communicated with the activity space of the steel ball 51.

[0035] In the present invention, preferably, the compensation mechanism 6 includes a connecting ring 60 , which is fixed to one side of the steel ball 51 and slides on the surface of the welding gun body 7 ; The positioning block 66 is fixed in the connecting ring 60 and is slidably connected to the moving plate 65; Spring 1 64, provided with four and fixed between the positioning block 66 and the movable plate 65; Spring 1 64 is fixed to the middle of the movable plate 65 and the other end is fixed to the surface of the welding gun body 7. The fixing rod 63 slides on one side of the positioning block 66. The air pump 61 is fixed to the surface of the connecting ring 60; The transmission tube 62 compensation mechanism 6 and the limiting mechanism 3 are provided with two ends, which are respectively fixed to the two output ends of the air pump 61 and the other end is set in the positioning block 66.

[0036] It should be noted that the interior of the positioning block 66 is sealed to ensure that gas cannot leak; The positioning block 66, the moving plate 65, the spring 1 64, and the spring 1 64 are each provided with two groups to ensure the stability of the welding gun body 7 during movement compensation; The air pump 61 is electrically connected and controlled by wireless signal transmission through a controller (not shown) in the prior art.

[0037] During the implementation process, the metal eyeglass frame to be welded is first placed between the second limit block 34 and the first limit block 31, and the screw rod 1 36 is rotated to move the slider 33 along the screw rod 1 36 and the slide groove, and the second limit block 34 is moved toward the first limit block 31, so that the metal eyeglass frame is clamped between the clamping columns of the second limit block 34 and the first limit block 31. The turntable 30 is rotated and adjusted along the middle of the connecting plate 25 with the metal eyeglass frame clamped between the clamping columns of the second limit block 34 and the first limit block 31. Pull the connecting plate 25 longitudinally, and the connecting plate 25 brings the movable block 23 and the fixed block 22 to move and adjust along the guide column 1 21 and the sliding groove on the surface of the welding table 1 through the movable block 1 20. Pull the connecting plate 25 horizontally, and the connecting plate 25 brings the movable block 23 to move and adjust along the sliding groove on the guide column 2 24 and the fixed block 22, making it easier to adjust the position of the metal eyeglass frame. The steel ball 51 is rotated to adjust the angle along the inside of the docking block 50 with the compensation mechanism 6, the welding gun body 7, and the welding head 10. When the angle adjustment is completed, the sliding plate 54 is rotated. The sliding plate 54 rotates along the docking block 50, so that the two sets of sliding plates 54 and the clamping plates 52 move relative to each other along the inside of the docking block 50 to clamp the steel ball 51, thereby limiting the movement of the steel ball 51 and enabling the angle to be locked after adjustment to avoid position deviation during the welding process. The threaded column 11 is rotated, and the threaded column 11 rotates along the middle of the support block 4, so that the connecting rod 12 moves downward along the slide groove on one side of the support block 4 and the threaded column 11. The connecting rod 12 moves downward with the angle adjustment mechanism 5, the compensation mechanism 6, the welding gun body 7, and the welding head 10, so that the welding head 10 contacts the solder on the surface of the metal eyeglass frame limited in the middle of the clamping column; When the welding head 10 contacts and welds the metal eyeglass frame, the actual welding contact may be false due to the thermal expansion of the eyeglass frame material. At this time, an air pump 61 is set. The air pump 61 delivers air pressure to the inside of the positioning block 66 through the transmission tube 62 and the fixed rod 63, so that the movable plate 65 squeezes the spring 1 64 and pushes the fixed rod 63. The fixed rod 63 moves downward along the middle of the connecting ring 60 with the welding gun body 7 and the welding head 10, thereby automatically compensating the distance and improving the welding efficiency.
