[0011] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0012] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0013] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-10 An automatic calibration valve housing assembly device includes a base 1, a dual-station switching mechanism 2, an automatic valve seat assembly mechanism 3, and a valve plate self-calibration assembly mechanism 4; the dual-station switching mechanism 2 for driving the valve to rotate is installed on the upper right side of the base 1. The front side of the dual-station rotation mechanism 2 is set as the loading station; the rear side of the dual-station rotation mechanism 2 is set as the unloading station. like Figure 1 As shown, the dual-station switching mechanism 2 includes a rotating assembly and a placement plate 23; the rotating assembly is installed on the upper end of the base 1; the placement plate 23 is symmetrically installed on the front and rear sides of the rotating assembly; the placement plate 23 is provided with a contoured groove 24 for fixing the valve housing; An automatic valve seat assembly mechanism 3 for folding the valve seat and placing it into the valve is installed on the upper left front of the base 1; like Figure 1 As shown, the automatic valve seat assembly mechanism 3 includes a linear module 31, a vertical moving component, a synchronous moving folding mechanism, a feeding platform 314, and a limiting plate 315. The linear module 31 is fixedly installed on the upper left side of the base 1 via a bracket. The vertical moving component is installed on the movable end of the linear module 31. The synchronous moving folding mechanism is installed on the vertical moving component. The feeding platform 314 is fixedly installed on the upper left front of the base 1. The limiting plate 315 is fixedly installed on the upper right side of the feeding platform 314. A valve plate self-calibration assembly mechanism 4 for assembling the valve plate and the valve housing is installed on the upper rear side of the base 1; The valve plate self-calibration assembly mechanism 4 includes a clamping and flipping assembly 49, a calibration and positioning assembly, and an installation assembly; the calibration and positioning assembly is installed on the upper rear side of the base 1; the installation assembly is connected to the calibration and positioning assembly; the clamping and flipping assembly 49 is also installed on the calibration and positioning assembly. In this invention, the valve housing that needs to be assembled is placed into the contour groove 24 on the loading station placement plate 23 by a loading robot, and then the valve seat is placed on the upper end of the unloading platform 314, and the right end of the valve seat is limited and blocked by the limiting plate 315. Then the vertical moving component works to drive the synchronous moving folding mechanism to move downward until the synchronous moving folding mechanism contacts the valve seat. Then the synchronous moving folding mechanism works to fold and retract the valve seat and fix the valve seat. Then the vertical moving component works again to drive the synchronous moving folding mechanism to move upward. The linear module 31 moves the folded valve seat to the top of the valve housing at the loading station. Then, the vertical moving component moves the valve seat downward. When the valve seat moves into the valve seat mounting slot inside the valve housing, the synchronous moving folding mechanism works again to release the folding clamp on the valve seat. Since the valve seat is made of rubber, it will automatically return to its original position and fit tightly against the inner wall of the valve housing. Then, the vertical moving component and the linear module 31 reset. Subsequently, the rotating component works to drive the placement plate 23 to rotate, so that the valve shell with the valve seat assembly completed moves to the unloading station; Subsequently, the calibration and positioning component moves to the top of the valve housing at the unloading station; and the loading robot moves the valve plate vertically to the rear side, the clamping and flipping component 49 works to adsorb and fix the valve plate, and drives the valve plate to rotate to the left to the unloading station. During the movement, the mounting holes on the valve plate will align with the calibration and positioning component. If there is a deviation between the mounting hole of the valve plate and the calibration positioning component, the clamping and flipping component 49 will also work to drive the valve plate to rotate until the mounting hole of the valve plate is aligned with the calibration positioning component; and the mounting component will work to fix the upper end of the valve plate; then the clamping and flipping component 49 will release the suction of the valve plate and rotate to the right to reset. The installation assembly then continues to work, pushing the valve plate along the calibration positioning assembly and valve seat, moving it into the valve housing until the valve plate is aligned with the mounting hole of the valve seat; Subsequently, the valve stem loading robot inserts the valve stem into the valve body through the mounting hole on the left side of the valve housing, and passes through the valve seat and valve plate to fix the valve seat and valve plate to the valve housing, thereby realizing the assembly operation of the valve housing; Subsequently, the unloading robot removes the assembled valve shell from the contour groove 24 at the unloading station; then the rotating component drives the placement plate 23 back to the loading station; and by repeating the above operation, continuous assembly of the valve shell can be achieved. By combining the vertical moving component and the synchronous moving folding mechanism, the device can automatically fold and retract the valve seat, and control the folded valve seat to complete the alignment and assembly with the valve, reducing the extra workload of manually folding the valve seat. By cooperating with the clamping and flipping assembly 49, the calibration and positioning assembly, and the installation assembly, the device can achieve continuous automatic feeding of the valve plate and can also automatically calibrate the position of the valve plate, so that the valve plate and the valve seat are precisely aligned, further improving the practicality of the device.

[0014] Example 2: In some embodiments, such as Figures 2-6 In a preferred embodiment of the present invention, the rotating assembly includes a rotating disk 21 and a first rotating cylinder 22; the rotating disk 21 is rotatably mounted on the upper right side of the base 1; the first rotating cylinder 22 is fixedly mounted in the middle of the base 1; and the output end of the first rotating cylinder 22 is fixedly connected to the rotating disk 21; placement plates 23 are symmetrically fixedly mounted on the front and rear sides of the upper end of the rotating disk 21. like Figure 4 As shown, the vertical moving assembly includes a fixed plate 32, a vertical push cylinder 33, a first guide rod 34, and a U-shaped fixed plate 35; the fixed plate 32 is fixedly installed on the movable end of the linear module 31; the vertical push cylinder 33 is fixedly installed on the upper end of the fixed plate 32; the first guide rod 34 is slidably connected to the fixed plate 32; the lower end of the first guide rod 34 is fixedly connected to the U-shaped fixed plate 35; the output end of the vertical push cylinder 33 is fixedly connected to the U-shaped fixed plate 35; the U-shaped fixed plate 35 is connected to the synchronous moving folding mechanism. like Figure 5As shown, the synchronous moving folding mechanism includes a driving bevel gear 36, a first driven bevel gear 37, a second driven bevel gear 38, a first rotating rod 39, a second rotating rod 310, a first rotating plate 311, a second rotating plate 312, a fixed folding rod 313, a driving motor 316, and a movable folding rod 317. The driving motor 316 is fixedly installed at the left end of the U-shaped fixed plate 35. The driving bevel gear 36 is rotatably installed on the left inner wall of the U-shaped fixed plate 35. The output end of the driving motor 316 is fixedly connected to the driving bevel gear 36. The first driven bevel gear 37 is rotatably installed on the upper inner wall of the U-shaped fixed plate 35. The second driven bevel gear 38 is rotatably installed on the lower inner wall of the U-shaped fixed plate 35. The lower end of the first driven bevel gear 37 is fixedly connected to the first rotating rod 39. The lower end of the second driven bevel gear 38 is fixedly connected to the second rotating rod 310. The first rotating rod 39 is located inside the second rotating rod 310, and the first rotating rod 39 and the second rotating rod 310 are in a limited sliding connection. The second rotating plate 312 is rotatably mounted on the lower end of the U-shaped fixed plate 35; the upper left side of the first rotating plate 311 is rotatably connected to the lower left side of the second rotating plate 312; the first rotating rod 39 is fixedly connected to the first rotating plate 311; and the second rotating rod 310 is fixedly connected to the second rotating plate 312. The fixed folding rod 313 is fixedly installed on the lower left side of the first rotating plate 311; the movable folding rod 317 is fixedly installed on the lower right side of both the first rotating plate 311 and the second rotating plate 312. In this invention, the valve housing that needs to be assembled is placed into the contour groove 24 on the loading station placement plate 23 by a loading robot, and then the valve seat is placed on the upper end of the unloading platform 314, and the right end of the valve seat is limited and blocked by the limiting plate 315. Subsequently, the vertical push cylinder 33 works to push the U-shaped fixed plate 35 to move downwards following the first guide rod 34 until the fixed folding rod 313 abuts against the left side of the outer ring of the valve seat; and the two movable folding rods 317 abut against the front and rear sides of the inner ring of the valve seat; then the drive motor 316 works to drive the drive bevel gear 36 to rotate, and the drive bevel gear 36 rotates to drive the first driven bevel gear 37 and the second driven bevel gear 38 to rotate synchronously in opposite directions; The rotation of the first driven bevel gear 37 drives the first rotating rod 39 to rotate, causing the first rotating plate 311 to rotate clockwise to the left along with the first rotating rod 39. The rotation of the second driven bevel gear 38 drives the second rotating rod 310 to rotate, causing the second rotating plate 312 to rotate counterclockwise to the left along with the second rotating rod 310. like Figure 6As shown, at this time, the first rotating plate 311 and the second rotating plate 312 will drive the movable folding rod 317 to rotate together. At this time, the movable folding rod 317 will push the valve seat to move together. Since the fixed folding rod 313 remains in a fixed position and always keeps in contact with the left side of the outer ring of the valve seat, the left side of the valve seat is limited. At this time, the parts of the valve seat pushed by the movable folding rod 317 on the front and rear sides will flip and fold towards the fixed folding rod 313 until the two movable folding rods 317 are to the left of the fixed folding rod 313. At this time, the left side of the valve seat will be folded into a "V" shape and contact the front and rear sides of the fixed folding rod 313. Because the valve seat is made of rubber, it always maintains its restoring force after being compressed and folded by the movable folding rod 317; and the positions of the movable folding rod 317 and the fixed folding rod 313 are fixed, so the valve seat will be limited and clamped by the fixed folding rod 313 and the movable folding rod 317. like Figure 6 As shown, the vertical push cylinder 33 then pulls the limiting plate 315 upward, causing the lower end of the valve seat to separate from the feeding platform 314. Then, the linear module 31 moves the limiting plate 315 to the right until the right end of the folded valve seat aligns with the inner wall of the right side of the valve. Next, the vertical push cylinder 33 moves the limiting plate 315 downward, causing the right end of the valve seat to fit against the inner wall of the right side of the valve. The drive motor 316 drives the drive bevel gear 36 to rotate, causing the first rotating plate 311 and the second rotating plate 312 to rotate to the right and reset. At this time, the movable folding rods 317 on both the front and rear sides... This will push the front and rear sides of the valve seat outward until the front and rear sides of the valve seat are in contact with the front and rear inner walls of the valve housing, and will also cause the left side of the valve seat to separate from the front and rear sides of the fixed bending rod 313; then the vertical push cylinder 33 works to drive the limiting plate 315 to move upward, so that the movable bending rod 317 and the fixed bending rod 313 are separated from the valve seat. At this time, the valve seat will automatically return to a circular shape and fit with the inner wall of the valve housing; at this time, the mounting holes on the valve seat are aligned with the mounting holes on the left and right sides of the valve housing; then the linear module 31 works to drive the limiting plate 315 to move to the left and reset. Subsequently, the first rotary cylinder 22 operates, driving the rotating disk 21 to rotate, which moves the valve shell with the valve seat assembled to the unloading station for the next step of valve plate installation.

[0015] Example 3: In some embodiments, such as Figures 7-10As shown, in a preferred embodiment of the present invention, the calibration and positioning assembly includes a vertical plate 41, a first horizontal push cylinder 42, a U-shaped movable plate 43, a positioning post 44, and a return spring 45; the vertical plate 41 is fixedly installed on the upper rear side of the base 1; the first horizontal push cylinder 42 is fixedly installed on the rear end of the vertical plate 41; the output end of the first horizontal push cylinder 42 is fixedly connected to the U-shaped movable plate 43; the left and right sides of the U-shaped movable plate 43 are limited and slidably connected to the vertical plate 41; and positioning posts 44 are slidably installed on the inner sides of the left and right ends of the front of the U-shaped movable plate 43. The two positioning posts 44 on the left and right sides have spherical surfaces at their closest ends; the diameter of the spherical surfaces is the same as the diameter of the mounting holes on the valve plate. Furthermore, one end of the return spring 45 is fixedly connected to the positioning post 44; the other end of the return spring 45 is fixedly connected to the U-shaped movable plate 43. like Figure 7 and Figure 8 As shown, the clamping and flipping assembly 49 includes a second rotary cylinder 491, a flipping plate 492, a rotating plate 493, a servo motor 494, a suction cup 495, a mounting plate 496, a pneumatic slip ring 497, a second horizontal push cylinder 498, and a square movable frame 499; the mounting plate 496 is fixedly installed on the front right side of the upright plate 41; the second horizontal push cylinder 498 is fixedly installed on the front inner wall of the mounting plate 496; the left and right sides of the middle part of the square movable frame 499 are slidably connected to the front end of the mounting plate 496; the output end of the second horizontal push cylinder 498 is fixedly connected to the rear inner wall of the square movable frame 499. The second rotary cylinder 491 is fixedly installed on the inner front wall of the square movable frame 499; the flip plate 492 is rotatably installed at the front end of the square movable frame 499; the output end of the second rotary cylinder 491 is fixedly connected to the flip plate 492; a pneumatic slip ring 497 is installed on the left rear end of the flip plate 492; and a servo motor 494 is fixedly installed on the left front end of the flip plate 492. The stator of the pneumatic slip ring 497 is fixedly connected to the left rear end of the flip plate 492; the rotor of the pneumatic slip ring 497 is fixedly connected to the output end of the servo motor 494; a rotating plate 493 is also fixedly installed on the rotor of the pneumatic slip ring 497; suction cups 495 are symmetrically fixedly installed on the upper and lower rear ends of the rotating plate 493; the suction cups 495 are connected to the rotor of the pneumatic slip ring 497 through air pipes; the stator of the pneumatic slip ring 497 is connected to an external air pump through air pipes. like Figure 7 and Figure 8As shown, the mounting assembly includes a vertical push cylinder 46, a movable plate 47, a second guide rod 48, a horizontal plate 410, and a clamping plate 411; the horizontal plate 410 is fixedly mounted on the upper end of the vertical plate 41; the vertical push cylinder 46 is fixedly mounted on the upper end of the horizontal plate 410; the output end of the vertical push cylinder 46 is fixedly connected to the upper end of the movable plate 47; the second guide rod 48 is fixedly connected to the movable plate 47; and the second guide rod 48 is slidably connected to the horizontal plate 410; the clamping plate 411 is fixedly mounted on the lower middle part of the movable plate 47; a slot is provided on the clamping plate 411; the opening size of the slot is the same as the width of the valve plate; In this invention, after the valve housing with the valve seat assembly completed is moved to the unloading station, the first horizontal push cylinder 42 works to pull the U-shaped movable plate 43 forward along the vertical plate 41 until the positioning pins 44 installed on the inner sides of the left and right ends of the front of the U-shaped movable plate 43 are aligned with the mounting holes on the left and right sides of the valve housing. At this point, the loading robot moves the valve plate vertically to the rear of the suction cup 495. Then, the suction cup 495 works to adsorb and fix the valve plate. Subsequently, the second rotary cylinder 491 works to drive the flipping plate 492 to rotate 180 degrees to the left. The flipping plate 492 drives the valve plate to rotate together. During the rotation, the left and right sides of the valve plate will contact the spherical surfaces of the positioning pins 44 installed on the inner sides of the left and right ends of the front of the U-shaped movable plate 43, and push the two positioning pins 44 to move in opposite directions at the same time and compress the return spring 45. Until the mounting hole on the valve plate is aligned with the spherical surface of the positioning pin 44, the return spring 45 returns to its original position and drives the positioning pin 44 to return to its original position. At this time, the spherical surface of the positioning pin 44 is in the mounting hole of the valve plate, realizing the limitation of the valve plate. At this time, the lower left and right ends of the valve plate are in contact with the valve seat inside the valve shell. If the valve plate is flipped and the mounting hole of the valve plate is misaligned with the spherical surface of the positioning post 44, the servo motor 494 will work to drive the rotor of the pneumatic slip ring 497 to rotate. At this time, the rotating plate 493 will follow the rotor of the pneumatic slip ring 497 to rotate, so that the suction cup 495 drives the valve plate to rotate until the mounting hole of the valve plate and the spherical surface of the positioning post 44 are aligned and engaged. Subsequently, the vertical push cylinder 46 works to push the movable plate 47 to move downwards following the second guide rod 48. During the movement, the slot on the clamping plate 411 engages with the upper end of the valve plate. Then, the suction cup 495 releases its adsorption on the valve plate, and the second horizontal push cylinder 498 works to pull the square movable frame 499 forward along the mounting plate 496, causing the suction cup 495 to separate from the valve plate. Then, the second rotary cylinder 491 works to drive the flipping plate 492 to rotate to the right and reset. Subsequently, the vertical push cylinder 46 continues to work, pushing the movable plate 47 downward, so that the slot on the clamping plate 411 pushes the valve plate to move downward along the valve seat. During the movement, the mounting holes of the valve plate will push the left and right positioning pins 44 to move in opposite directions until the left and right sides of the valve plate are separated from the positioning pins 44. Since the valve seat is made of rubber, the valve plate will continuously squeeze the inner wall of the valve seat during the downward movement, so that the inner wall of the valve seat applies pressure to the valve plate. Under the pushing action of the clamping plate 411, the valve plate is kept vertical and moves downward until the valve plate is aligned with the mounting holes on the left and right sides of the valve seat. Subsequently, the valve stem feeding robot inserts the valve stem into the valve through the mounting hole on the left side of the valve housing, and passes through the valve seat and valve plate to fix the valve seat and valve plate to the valve housing, thereby realizing the assembly operation of the valve housing; after the assembly is completed, the vertical push cylinder 46 works to drive the movable plate 47 to reset upward; the first horizontal push cylinder 42 works to drive the U-shaped movable plate 43 to reset backward.
