[0021] Embodiment 2, based on embodiment 1, Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7The damping downward pressure adjustment assembly includes a control box 2 fixedly mounted on the top of the support box 1, and the control box 2 is a cavity structure with an opening at the bottom. A first screw rod 5 is rotatably connected in the control box 2, and a first damping disk 6 is arranged below the first screw rod 5. The top of the first rotating shaft 7 is fixedly connected to a second damping disk 8 located in the control box 2, and the top of the second damping disk 8 is in contact with the bottom of the first damping disk 6. The first screw rod 5 is equipped with a pressure adjustment member for applying pressure to the first damping disk 6, and the outer sleeve of the first screw rod 5 is provided with a threaded The sleeve 62 is fixedly connected to a plurality of movable plates 3, and a plurality of avoidance holes 4 are provided on the side wall of the control box 2, and the number of the pressing plate 17, the movable plate 3 and the avoidance holes 4 is the same, the movable plate 3 passes through the corresponding avoidance holes 4, and the inner walls of the avoidance holes 4 on both sides are in contact with the two sides of the movable plate 3 respectively, and the end of the movable plate 3 away from the threaded sleeve 62 is connected to the pressing plate 17 through an elastic unit, the pressure adjustment member includes a first prism 9 fixedly mounted on the top of the first damping plate 6, and the bottom of the first screw rod 5 is provided with a first sliding The top of the first prism 9 is located in the first slide groove 10, and a movable block 11 located above the first prism 9 is arranged in the first slide groove 10. The movable block 11 and the first prism 9 are connected by a first compression spring 12. The top of the movable block 11 is fixedly connected with a second rotating shaft 13. The top of the second rotating shaft 13 passes through the control box 2. The outer rotating sleeve of the second rotating shaft 13 is provided with a movable frame 14 located above the control box 2. Two second screw rods 15 are passed through the movable frame 14. The bottom end of the second screw rod 15 is fixedly connected with the control box 2. The second screw rod 15 is sleeved with two nuts 16 on its outer side, and two adjacent nuts 16 are in contact with the top and bottom of the movable frame 14 respectively. The elastic unit includes a second prism 18 fixedly mounted on the top of the pressing plate 17. The end of the movable plate 3 away from the threaded sleeve 62 is fixedly connected with a first fixed column 19. A second slide groove 20 is provided at the bottom of the first fixed column 19. The top of the second prism 18 is located in the second slide groove 20, and the top of the second prism 18 and the top inner wall of the second slide groove 20 are connected by a second compression spring 21. The staff drives the movable frame 14 to slide vertically relative to the second screw rod 15. The movable frame 14 drives the movable block 11 to slide in the first slide groove 10 through the second rotating shaft 13, thereby changing the spacing between the movable block 11 and the first prism 9, and then adjusting the length of the first compression spring 12. The pressure applied by the first compression spring 12 to the first prism 9 and the first damping disk 6 changes, thereby adjusting the friction between the first damping disk 6 and the second damping disk 8. When the friction between the first damping disk 6 and the second damping disk 8 is adjusted, the staff drives the two adjacent nuts 16 to rotate so that the two adjacent nuts 16 clamp the movable frame 14, so that the movable frame 14 is fixed relative to the second screw rod 15 and the control box 2. The staff drives the turntable 58 to rotate so that the first rotating shaft 7 drives the second damping disk 8 to rotate. The second damping disk 8 drives the first damping disk 6, the first prism 9 and the first screw rod 5 to rotate through the friction force. After the threaded sleeve 62 and the movable plate 3 move downward and the pressing plate 17 slides into the accommodating groove 24, as the threaded sleeve 62 and the movable plate 3 continue to move downward, the first fixed column 19 moves downward relative to the second prism 18, the length of the second compression spring 21 becomes shorter, and the second compression spring 21 applies pressure to the second prism 18 and the pressing plate 17. When the resistance of the movable plate 3 and the first fixed column 19 to move downward is equal to the friction between the first damping plate 6 and the second damping plate 8, as the first rotating shaft 7 and the second damping plate 8 continue to rotate, the second damping plate 8 cannot drive the first damping plate 6 to rotate synchronously by friction, and the movable plate 3 and the first fixed column 19 stop moving downward, so that the pressing plate 17 controls the force between the metal cavity, the sapphire light window and the solder to reach a preset value and then stops increasing the pressure. By controlling the friction between the first damping plate 6 and the second damping plate 8, the force between the metal cavity, the sapphire light window and the solder can be controlled, thereby improving the scope of application.

At this time, the first rotating shaft 7 drives the second damping ring 35 to rotate synchronously, and the second damping ring 35 cannot drive the first damping ring 34 to rotate synchronously through the friction force. When the sapphire optical window and the metal package are brazed, the first rotating shaft 7 rotates in the opposite direction so that the first rotating shaft 7 drives the pressing plate 17 to move upward through the damping downward pressure adjustment component. When the pressing plate 17 is separated from the accommodating groove 24, the first rotating shaft 7 drives the second damping ring 35 to rotate synchronously, and the second damping ring 35 drives the first damping ring 34 and the rotating frame 61 to rotate through the friction force. The rotating frame 61 drives the toothed plate 32 through the gear ring 33. When the first rotating shaft 7 rotates, the second damping ring 35 cannot drive the first damping ring 34 to rotate synchronously by friction, so that the ejection disk 27 moves up to the preset position and then stops automatically. Similarly, when the first rotating shaft 7 rotates to make the ejection disk 27 move down to the ejection hole 26, the second damping ring 35 cannot drive the first damping ring 34 to rotate synchronously by friction again, so that the ejection disk 27 moves down to the preset position and then stops automatically.

The inner wall of the guide hole 52 away from the adjusting ring 39 is provided with a second through hole 53, and a plug plate 54 is provided in the second through hole 53. The guide plate 49 is provided with three plug holes 57 adapted to the plug plate 54, one end of the plug plate 54 is located in the corresponding plug hole 57, and the other end of the plug plate 54 is fixedly connected with at least one supporting portion 55, and the supporting portion 55 and the fixing block 47 are connected by a tension spring 56. A plurality of supporting legs 60 are fixedly connected to the bottom of the support box 1, and a hexagonal groove 59 is provided at the bottom of the turntable 58; When the pressing plate 17 slides into the receiving groove 24 and gets stuck, the second damping plate 8 cannot drive the first damping plate 6 to rotate by friction, so that the pressing plate 17 cannot slide out of the receiving groove 24, the staff drives the plug plate 54 and the support portion 55 to move, so that the plug plate 54 is disengaged from the corresponding socket 57, and the tension spring 56 is in a stretched state, the staff drives the fixing block 47 to move upward relative to the guide plate 49, so that the plug plate 54 moves to one side of the socket 57 located at the top, the staff drives the end of the plug plate 54 to be inserted into the corresponding socket 57 again, and the tension spring 56 recovers its deformation. During the upward movement of the fixing block 47 and the adjusting ring 39, The adjusting ring 39 pushes the movable ring 36, the second fixed column 43 and the positioning column 45 upward through the slider 41, and the guide block 37 slides in the guide groove 38. The design of the guide block 37 and the guide groove 38 allows the movable ring 36 to move smoothly relative to the first rotating shaft 7. At this time, the top of the positioning column 45 located above the movable ring 36 abuts against the bottom of the first damping disk 6, and the third compression spring 46 is in a compressed state. When the first rotating shaft 7 rotates again, the first rotating shaft 7 drives the positioning column 45 to rotate synchronously through the second damping disk 8. When the positioning column 45 moves to just below the positioning hole 42 on the first damping disk 6, the third compression spring 46 pushes the positioning column 45 moves so that the top end of the positioning post 45 located above the movable ring 36 is inserted into the corresponding positioning hole 42 on the first damping plate 6. When the first rotating shaft 7 rotates again, the first rotating shaft 7 and the second damping plate 8 drive the first damping plate 6 and the first prism 9 to rotate synchronously through the positioning post 45, so that the pressing plate 17 can slide out of the receiving groove 24. When the upward movement resistance of the ejection plate 27 is greater than the preset value, the ejection plate 27 cannot eject the workpiece from the receiving groove 24. Similarly, the staff inserts the end of the insert plate 54 into a plug hole 57 located at the bottom. When the first rotating shaft 7 drives the positioning post 45 to rotate synchronously through the second damping ring 35, the workpiece located at the movable ring 36 is pushed out of the movable ring 36. The bottom end of the positioning column 45 below the ring 36 is inserted into the corresponding positioning hole 42 on the first damping ring 34. As the first rotating shaft 7 continues to rotate, the first rotating shaft 7 and the second damping ring 35 drive the first damping ring 34 to rotate synchronously through the positioning column 45, so that the ejection disk 27 can be moved up to ensure that the ejection disk 27 ejects the workpiece from the accommodating groove 24. The support box 1 can be supported by the design of the support leg 60. The staff inserts the end of the hexagonal wrench into the hexagonal groove 59, and the turntable 58 can be driven to rotate by the hexagonal wrench. When the first rotating shaft 7 and the movable ring 36 rotate, the movable ring 36 drives the slider 41 to slide in the annular groove 40.

[0024] A method for brazing a sapphire optical window and a metal package in this embodiment uses the above-mentioned sapphire optical window and metal package brazing device, and includes the following steps: Step 1: The staff sequentially puts the metal cavity, the sapphire window and the solder into each receiving groove 24, and then drives the pressing plate 17 downward through the damping downward pressure adjustment component to make the pressing plate 17 slide into the receiving groove 24; Step 2: Adjust the downward pressure of the pressing plate 17 through the damping pressing adjustment component, and control the force between the metal cavity, the sapphire window and the solder through the pressing plate 17; Step 3: Place the entire device into a sintering tunnel furnace and braze at high temperature; Step 4: After brazing is completed, the entire device is taken out from the sintering tunnel furnace, the pressing plate 17 is driven out of the receiving groove 24 by the damping downward pressure adjustment component, and the packaged workpiece is ejected from the receiving groove 24 by the lifting and picking structure.

[0025] Working principle: During operation, the staff puts the metal cavity, sapphire window and solder into each receiving slot 24 in turn, and then drives the pressing plate 17 downward through the damping downward pressure adjustment component to make the pressing plate 17 slide into the receiving slot 24, and adjusts the downward pressure of the pressing plate 17 through the damping downward pressure adjustment component. The force between the metal cavity, sapphire window and solder is controlled by the pressing plate 17, and then the whole device is placed in the sintering tunnel furnace for brazing at high temperature. The tunnel furnace sintering can accurately control the furnace temperature, atmosphere and time. , to ensure the quality of brazing. When brazing is completed, the entire device is taken out of the sintering tunnel furnace, and the pressing plate 17 is driven to separate from the receiving groove 24 by the damping downward pressure adjustment component, and the packaged workpiece is ejected from the receiving groove 24 by the lifting and picking structure. The downward pressure of the pressing plate 17 can be adjusted according to actual needs by the damping downward pressure adjustment component, and then the force between the metal cavity, the sapphire light window and the solder can be controlled by the pressing plate 17. Multiple groups of sapphire light windows and metals can be packaged and brazed, which improves the scope of application and brazing efficiency. The staff drives the movable frame 14 to slide vertically relative to the second screw rod 15. The movable frame 14 drives the movable block 11 to slide in the first slide groove 10 through the second rotating shaft 13, thereby changing the spacing between the movable block 11 and the first prism 9, and then adjusting the length of the first compression spring 12. The pressure applied by the first compression spring 12 to the first prism 9 and the first damping disk 6 changes, thereby adjusting the friction between the first damping disk 6 and the second damping disk 8. When the friction between the first damping disk 6 and the second damping disk 8 is adjusted, the staff drives the two adjacent nuts 16 to rotate so that the two adjacent nuts 16 clamp the movable frame 14, so that the movable frame 14 is fixed relative to the second screw rod 15 and the control box 2. The staff drives the turntable 58 to rotate so that the first rotating shaft 7 drives the second damping disk 8 to rotate. The second damping disk 8 drives the first damping disk 6, the first prism 9 and the first screw rod 5 to rotate through the friction force. After the threaded sleeve 62 and the movable plate 3 move downward and the pressing plate 17 slides into the accommodating groove 24, as the threaded sleeve 62 and the movable plate 3 continue to move downward, the first fixed column 19 moves downward relative to the second prism 18, the length of the second compression spring 21 becomes shorter, and the second compression spring 21 applies pressure to the second prism 18 and the pressing plate 17. When the resistance of the movable plate 3 and the first fixed column 19 moving downward is equal to the friction between the first damping plate 6 and the second damping plate 8, as the first rotating shaft 7 and the second damping plate 8 continue to rotate, the second damping plate 8 cannot drive the first damping plate 6 to rotate synchronously by friction, and the movable plate 3 and the first fixed column 19 stop moving downward, so that the pressing plate 17 controls the force between the metal cavity, the sapphire light window and the solder to reach a preset value and stops increasing the pressure. By controlling the friction between the first damping plate 6 and the second damping plate 8, the force between the metal cavity, the sapphire light window and the solder can be controlled, thereby improving the scope of application. When the first rotating shaft 7 rotates so that the first rotating shaft 7 drives the pressing plate 17 to move downward through the damping downward pressure adjustment component, the ejection plate 27 is located in the ejection hole 26, and the ejection plate 27, the first connecting column 29 and the movable seat 28 cannot move downward. At this time, the first rotating shaft 7 drives the second damping ring 35 to rotate synchronously, and the second damping ring 35 cannot drive the first damping ring 34 to rotate synchronously through the friction force. When the sapphire optical window and the metal package are brazed, the first rotating shaft 7 rotates in the opposite direction so that the first rotating shaft 7 drives the pressing plate 17 to move upward through the damping downward pressure adjustment component. When the pressing plate 17 is separated from the accommodating groove 24, the first rotating shaft 7 drives the second damping ring 35 to rotate synchronously, and the second damping ring 35 drives the first damping ring 34 and the rotating frame 61 to rotate through the friction force. The rotating frame 61 drives the toothed plate 32 through the gear ring 33. When the first rotating shaft 7 rotates, the second damping ring 35 cannot drive the first damping ring 34 to rotate synchronously by friction, so that the ejection disk 27 automatically stops after moving up to the preset position. Similarly, when the first rotating shaft 7 rotates to make the ejection disk 27 move down to the ejection hole 26, the second damping ring 35 cannot drive the first damping ring 34 to rotate synchronously by friction again, so that the ejection disk 27 automatically stops after moving down to the preset position. When the pressing plate 17 slides into the receiving groove 24 and gets stuck, the second damping plate 8 cannot drive the first damping plate 6 to rotate by friction, so that the pressing plate 17 cannot slide out of the receiving groove 24, the staff drives the plug plate 54 and the support portion 55 to move, so that the plug plate 54 is disengaged from the corresponding socket 57, and the tension spring 56 is in a stretched state, the staff drives the fixing block 47 to move upward relative to the guide plate 49, so that the plug plate 54 moves to one side of the socket 57 located at the top, the staff drives the end of the plug plate 54 to be inserted into the corresponding socket 57 again, and the tension spring 56 recovers its deformation. During the upward movement of the fixing block 47 and the adjusting ring 39, The adjusting ring 39 pushes the movable ring 36, the second fixed column 43 and the positioning column 45 upward through the slider 41, and the guide block 37 slides in the guide groove 38. The design of the guide block 37 and the guide groove 38 allows the movable ring 36 to move smoothly relative to the first rotating shaft 7. At this time, the top of the positioning column 45 located above the movable ring 36 abuts against the bottom of the first damping disk 6, and the third compression spring 46 is in a compressed state. When the first rotating shaft 7 rotates again, the first rotating shaft 7 drives the positioning column 45 to rotate synchronously through the second damping disk 8. When the positioning column 45 moves to just below the positioning hole 42 on the first damping disk 6, the third compression spring 46 pushes the positioning column 45 moves so that the top end of the positioning post 45 located above the movable ring 36 is inserted into the corresponding positioning hole 42 on the first damping plate 6. When the first rotating shaft 7 rotates again, the first rotating shaft 7 and the second damping plate 8 drive the first damping plate 6 and the first prism 9 to rotate synchronously through the positioning post 45, so that the pressing plate 17 can slide out of the receiving groove 24. When the upward movement resistance of the ejection plate 27 is greater than the preset value, the ejection plate 27 cannot eject the workpiece from the receiving groove 24. Similarly, the staff inserts the end of the insert plate 54 into a plug hole 57 located at the bottom. When the first rotating shaft 7 drives the positioning post 45 to rotate synchronously through the second damping ring 35, the workpiece located at the movable ring 36 is pushed out of the movable ring 36. The bottom end of the positioning column 45 below the ring 36 is inserted into the corresponding positioning hole 42 on the first damping ring 34. As the first rotating shaft 7 continues to rotate, the first rotating shaft 7 and the second damping ring 35 drive the first damping ring 34 to rotate synchronously through the positioning column 45, so that the ejection disk 27 can be moved up to ensure that the ejection disk 27 ejects the workpiece from the accommodating groove 24. The support box 1 can be supported by the design of the support leg 60. The staff inserts the end of the hexagonal wrench into the hexagonal groove 59, and the turntable 58 can be driven to rotate by the hexagonal wrench. When the first rotating shaft 7 and the movable ring 36 rotate, the movable ring 36 drives the slider 41 to slide in the annular groove 40.
