Technical Field

[0001] The present invention relates to the technical field of sapphire welding, and in particular to a sapphire and metal positioning welding device and method. Background Art

[0002] Sapphire (high-purity single-crystal aluminum oxide) is a precious material that is widely used in various fields, especially in the optoelectronics and semiconductor industries, due to its extremely high hardness, excellent optical properties and chemical stability. First of all, as a transparent material, high-purity single-crystal aluminum oxide sapphire can be used as a window or lens in optical instruments, lasers, infrared science and other fields. In lasers, it can be used as a laser medium to achieve laser enhancement and precision control. This is mainly because high-purity single-crystal aluminum oxide sapphire has very high optical transparency and refractive index, which can help the laser beam to propagate and adjust quickly, thereby obtaining a more accurate and clear laser output. High-purity single-crystal aluminum oxide sapphire has a wide range of applications, covering many fields, and the many functions and characteristics included in it make it an ideal choice in many high-performance and high-precision applications.

[0036] Working principle: When using the welding device, the screw 11 is rotated to drive the leveling seat 13 to rise and fall in the nut column 12, so as to perform a leveling operation on the welding device. When welding the pre-assembled sapphire lens and the lens barrel, first open the opening and closing panel 7, place the lens barrel inside the two clamping plates 643, and then start the servo motor 1 619, and drive the linkage round rod 626 through the servo motor 1 619 to make the worm 1 631 rotate, and drive the bevel gear 1 629 to rotate through the worm 1 631, and drive the rotating shaft 628 to rotate through the bevel gear 1 629, so that the rotating shaft 628 drives the bevel gear 2 630 to make The worm 2 632 moves outside the angle rotating rod 624, so that the worm 2 632 drives the bevel gear 3 639 to rotate, and the bevel gear 3 639 drives the bidirectional screw 638 to rotate so that the U-shaped clamping slide plate 637 moves relatively, so that the clamping plate 643 clamps and fixes the lens barrel, and then the screw motor 606 is started, and the belt 605 is driven by the screw motor 606 to rotate the screw 604, so that the screw 604 drives the tooling moving plate 602 to move in the slide groove on the welding workbench 3 to the bottom of the laser welder body 610. At the same time, before welding, the heating box 616 is started, and the pump body 615 is used to heat the workpiece 602. The heat is transferred to the hollow arc-shaped air-blowing frame 617, thereby preheating the lens barrel. During the preheating process, by starting the servo motor 2 620, the adjusting gear 1 621 on the servo motor 2 620 drives the linkage gear 1 623 so that the angle rotating rod 624 drives the lens barrel clamped on the positioning clamping frame 635 on one side of the rotating fixed plate 634 to rotate, so that the heating is uniform. During the welding operation, the laser welder body 610 ventilates the smoke through the air outlet on the sealing cover plate 15, and at the same time starts the smoking pump 909 to absorb the smoke through the hollow arc-shaped suction plate 920 at the bottom of the hollow sliding frame 912, and then passes through The filter head 910 filters and discharges the smoke, and at the same time starts the electric drive rod 907 to drive the linkage gear rod 906 to move back and forth horizontally in the limiting track 905, so that the linkage gear rod 906 drives the adjusting gear 904 to drive the rotating tube 903 to rotate in both directions, so that the linkage gear 919 at one end of the rotating support rod 911 rotates under the limitation of the arc-shaped limiting gear plate 913, so that the pushing circular plate 917 drives the push-pull rod 918 to make the hollow arc-shaped suction plate 920 at the bottom of the hollow sliding frame 912 slide in both directions in the limiting groove on the rotating support rod 911, so as to evenly absorb and discharge the smoke generated inside the protective frame 4.
