Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Refer to Figures 1-5, an embodiment provided by the present utility model: a laser welding device for bead stone accessories, including an adjustment frame 1. At the four corners of the bottom end of the adjustment frame 1, sliding rods 12 are fixedly connected. On the left and right sides of the top end of the bottom plate 11, support blocks 17 are fixedly connected. Inside the inner walls of the support blocks 17, connecting shafts 6 are rotatably connected. At one end of the top end of the bottom plate 11 near the left support block 17, a rotating motor 5 is fixedly connected. The left end of the left connecting shaft 6 penetrates through the outer wall of the support block 17 and is fixedly connected to the driving end of the rotating motor 5. At the opposite ends of the connecting shafts 6, a rotating frame 7 is fixedly connected. On the inner walls of the four sides of the bottom end of the positioning frame 8, threaded rods 18 are rotatably connected. Rubber clamping plates 19 are threadedly connected to the outer walls of the threaded rods 18. The outer ends of the threaded rods 18 on the four sides penetrate through the outer wall of the positioning frame 8. The bottom ends of the rubber clamping plates 19 are slidably connected to the inner wall of the positioning frame 8. At the bottom ends of the sliding rods 12, limit discs 9 are fixedly connected.
[0026] Specifically, the bottom plate 11 can slide up and down on the outer wall of the sliding rod 12 to change the distance from the adjustment frame 1. The support blocks 17 are used to support the rotation of the connecting shafts 6. The rotating motor 5 is used to drive the rotating frame 7 to rotate through the connecting shafts 6. The positioning frame 8 drives the rubber clamping plates 19 to slide on the inner wall of the positioning frame 8 through the rotation of the threaded rods 18 on the four sides to clamp and fix the outer wall of the jewelry accessories. The limit discs 9 are used to limit the position of the bottom plate 11 at the bottom end of the outer wall of the sliding rod 12.
[0027] A screw rod 3 is threadedly connected through the inner wall of the top end of the sliding frame 2. In the middle of the inner wall of the sliding frame 2, a linear motor 14 is fixedly connected. The inner wall of the laser welder 13 is slidably connected to the outer wall of the linear motor 14. The left and right ends of the outer wall of the screw rod 3 are rotatably connected to the inner wall of the adjustment frame 1. The right end of the screw rod 3 penetrates through the outer wall of the adjustment frame 1. The left and right ends of the outer wall of the laser welder 13 are slidably connected to the inner wall of the sliding frame 2
[0028] Specifically, then by rotating the screw rod 3, the sliding frame 2 slides left and right on the inner wall of the adjustment frame 1, and by controlling the linear motor 14, the laser welder 13 slides back and forth on the inner wall of the sliding frame 2, so as to adjust the precise position of the laser welder 13 to weld the jewelry accessories below.
[0029] At the opposite ends of the left and right telescopic plates 10, first tension springs 15 are fixedly connected. At the opposite ends of the left and right first tension springs 15, they are fixedly connected to the inner wall of the bottom plate 11. The opposite ends of the left and right telescopic plates 10 penetrate through the outer wall of the bottom plate 11. On the side near the outer wall of the sliding rod 12 at the opposite ends of the left and right telescopic plates 10, limit insertion posts 16 are fixedly connected. On the inner walls of the sliding rods 12, limit insertion holes 4 penetrating through the left and right sides are opened. The shapes of the outer walls of the limit insertion posts 16 are all in fit with the shapes of the inner walls of the limit insertion holes 4.
[0030] Specifically, pull the four-side telescopic plate 10 to stretch the first tension spring 15 and slide outward, so that the limit insertion post 16 is pulled out from the inner wall of the limit insertion hole 4, so that the bottom plate 11 can be slid upward on the outer wall of the slide rod 12 to a height convenient for laser welding. Then release the four-side telescopic plate 10 so that the limit insertion post 16 is inserted into the inner wall of the limit insertion hole 4 again under the action of the first tension spring 15 to limit the position of the bottom plate 11 on the outer wall of the slide rod 12, so as to freely adjust the welding distance and the welding position.
[0031] Both the outer walls of the front and rear connecting rods 21 are rotatably connected to the inner wall of the rotating frame 7. The front end of the front connecting rod 21 penetrates the outer wall of the rotating frame 7. A telescopic column 23 is slidably connected to the inner wall of the front end of the front connecting rod 21. A toothed cylinder 20 is fixedly connected to the front end of the telescopic column 23. A toothed groove is provided on the outer wall of the rotating frame 7 corresponding to the outer wall of the connecting rod 21. The shape of the outer wall of the toothed cylinder 20 is fitted with the shape of the toothed groove. A second tension spring 22 is fixedly connected to the rear end of the telescopic column 23. The front end of the second tension spring 22 is fixedly connected to the inner wall of the connecting rod 21. The inner wall of the toothed cylinder 20 is slidably connected to the outer wall of the connecting rod 21.
[0032] Specifically, pull the toothed cylinder 20 outward on the outer wall of the connecting rod 21, so that the telescopic column 23 stretches the second tension spring 22 and slides outward, so that the toothed cylinder 20 is disengaged from the outer wall of the rotating frame 7. Then rotate the toothed cylinder 20 so that the connecting rod 21 rotates to a suitable angle, so that the positioning frame 8 flips left and right in the inner wall of the rotating frame 7 and stops at a suitable angle. Release the toothed cylinder 20 and it will be re-fitted with the outer wall of the rotating frame 7 under the reset action of the second tension spring 22, so that laser welding can be performed on the welding part of the jewelry accessory at a better angular position.
[0033] Working principle: First, place the jewelry accessories to be laser welded in the middle of the inner wall of the positioning frame 8. Then, rotate the four-side threaded rod 18 to move the rubber clamping plate 19 towards the middle to clamp and fix the outer wall of the jewelry accessories. Then, rotate the screw rod 3 to make the sliding frame 2 slide left and right on the inner wall of the adjusting frame 1, and control the linear motor 14 to drive the laser welder 13 to slide back and forth on the inner wall of the sliding frame 2, so as to adjust the precise position of the laser welder 13 to weld the jewelry accessories below. At the same time, pull the four-side telescopic plate 10 to stretch the first tension spring 15 and slide outward, so that the limit insertion post 16 is pulled out from the inner wall of the limit insertion hole 4, so that the bottom plate 11 can slide upward on the outer wall of the sliding rod 12 to a height convenient for laser welding. Then, release the four-side telescopic plate 10 so that the limit insertion post 16 is inserted into the inner wall of the limit insertion hole 4 again under the action of the first tension spring 15 to limit the position of the bottom plate 11 on the outer wall of the sliding rod 12, so as to freely adjust the welding distance and welding position and improve the accuracy of the welding position. Rotate the motor 5 to drive the connecting shaft 6 to rotate, so that the rotating frame 7 and the positioning frame 8 are flipped in the front and back directions as a whole, and stop at a suitable angle. Then, pull the tooth cylinder 20 outward on the outer wall of the connecting rod 21, so that the telescopic column 23 stretches the second tension spring 22 and slides outward, so that the tooth cylinder 20 is disengaged from the outer wall of the rotating frame 7. Then, rotate the tooth cylinder 20 to make the connecting rod 21 rotate to a suitable angle, so that the positioning frame 8 is flipped left and right on the inner wall of the rotating frame 7 and stops at a suitable angle. Release the tooth cylinder 20, and it will be re-fitted with the outer wall of the rotating frame 7 under the reset action of the second tension spring 22, so that the laser welding can be performed on the welding part of the jewelry accessories at a better angular position.
