[0022] Refer to the following Figures 1 to 14 The embodiments of the present invention are described in detail. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0023] A micro-seal ring automatic assembly device, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6As shown, it includes an assembly device 1, a placement box 2 is fixedly installed on the top of the assembly device 1, the placement box 2 is a circular structure with an upper opening, and a taking hole is opened at the outer end of the placement box 2 to facilitate the removal of the piston rod 13, a supporting round rod 3 is coaxially fixedly installed on the inner bottom end of the placement box 2, and a center disc 4 is coaxially fixedly installed on the top of the supporting round rod 3. The center disc 4 is arranged in the upper port of the placement box 2, and a left bending rod 5 is fixedly installed on the left side of the top of the center disc 4. The left bending rod 5 is an "L"-shaped structure, and a positioning disc 6 is fixedly installed on the outer side of the top of the left bending rod 5. The top of the positioning disc 6 is opened There is a jack that passes through from top to bottom, the top of the sleeve shaft 8 is inserted into the jack, a screw is threadedly installed on the positioning disk 6, and the rotation of the screw can lock the sleeve shaft 8. The front and rear bottom ends of the positioning disk 6 are respectively fixed with downwardly extending solid rods 7, and the two solid rods 7 are symmetrically arranged front and back. The sleeve shaft 8 is arranged between the two solid rods 7. The sleeve shaft 8 is provided with a plurality of sealing rings 9, and the plurality of sealing rings 9 are evenly distributed along the axial direction of the sleeve shaft 8. A tapered rod is fixedly installed at the lower end of the sleeve shaft 8. The outer diameter of the tapered rod is the same as the outer diameter of the sleeve shaft 8, and the upper end diameter of the tapered rod is smaller than the lower end diameter (the tapered rod is a tapered structure, such as Figure 6 As shown), the lower ends of the two solid rods 7 are respectively fixedly mounted with first telescopic rods 10, the first telescopic rods 10 are electric telescopic rods, and are connected to a power supply and a controller, the lower ends of the two first telescopic rods 10 are respectively slidably mounted with semicircular pressing rings 11, the openings of the two pressing rings 11 are correspondingly arranged, a material discharge assembly is arranged on the right side of the center disc 4, the material discharge assembly can continuously release a piston rod 13, a self-rotating disc 12 is sleeved on the outer circumferential surface of the center disc 4, the self-rotating disc 12 is rotatably connected to the placement box 2, the center disc 4 is rotatably connected to the self-rotating disc 12, the self-rotating disc 12 is evenly provided with positioning assemblies, and each of the positioning assemblies is provided with a piston rod 13; The personnel place the assembly equipment 1 in a suitable area, and then easily sleeve the batch of sealing rings 9 on the sleeve shaft 8. At this time, there is a slight contact between every two sealing rings 9. After the sealing ring 9 is installed, the top of the sleeve shaft 8 is inserted into the jack from below the positioning plate 6, and the sleeve shaft 8 is locked with screws. Since the outer end of the sealing ring 9 is a circular structure, an inwardly recessed gap will be formed between the outer ends of every two sealing rings 9. Then the blanking assembly puts the piston rod 13 onto each positioning assembly, driving the lowest sealing ring 9 to slide down along the sleeve shaft 8 to the tapered rod, turning on the power, and the controller starts The two first telescopic rods 10 are moved, and the two first telescopic rods 10 push the corresponding pressing rings 11 to move downward. The two pressing rings 11 jointly press the falling sealing ring 9 to slide downward along the tapered rod. Since the diameter of the upper end of the tapered rod is smaller than the diameter of the lower end, the sealing ring 9 will gradually become larger during the sliding process, and finally the sealing ring 9 will slide along the tapered rod into the sealing ring groove of the piston rod 13, thereby completing the assembly of the sealing ring 9. Since the sealing ring 9 is automatically assembled, the assembly speed is greatly improved, the labor cost is reduced, the assembly accuracy can be controlled, the accurate assembly of the sealing ring 9 is ensured, and the physical strength of the personnel is also reduced.

[0024] like Figure 6 , Fig.10 , Fig.11 As shown, a fixing block 14 is fixedly installed on the mutually close ends below the two solid rods 7, and the fixing block 14 is arranged close to the sleeve shaft 8. A toggle wheel 15 is rotatably installed on the two fixing blocks 14, and the toggle wheel 15 is arranged corresponding to the center of the sleeve shaft 8. A plurality of toggle teeth are evenly fixedly installed on the circumferential outer wall of each toggle wheel 15, and the number of toggle teeth is set according to needs. A self-rotating gear 16 coaxially fixedly connected with the toggle wheel 15 is rotatably installed on the fixing block 14 located at the rear side, and a linkage gear 17 meshing with the self-rotating gear 16 is rotatably installed on the fixing block 14. The self-rotating gear 16 and the linkage gear 17 are arranged on the right side of the fixing block 14, and an extension rod is coaxially fixedly installed on the right end of the toggle wheel 15 on the front side and on the right end of the linkage gear 17, respectively. The pulley group 18 includes two pulleys and a belt, and the two extension rods are coaxially fixedly installed with pulleys, and a belt is connected between the two pulleys, and the belt is arranged away from the sleeve shaft 8. The personnel insert the top end of the sleeve shaft 8 into the socket from under the positioning plate 6, and use screws to lock the sleeve shaft 8. At this time, the two toggle teeth on the rear side and the two toggle teeth on the front side clamp the penultimate sealing ring 9 respectively, and the tip of the toggle tooth will enter the gap between the outer ends of each two sealing rings 9, and the sealing ring 9 will not slide downward. Then the pulley group 18 rotates with the two extension rods, and the linkage gear 17 engages with the rotation gear 16 to rotate, and the two toggle wheels 15 rotate synchronously. The two toggle teeth on the rear side and the two toggle teeth on the front side simultaneously toggle the penultimate sealing ring 9 to slide downward. A batch of sealing rings 9 will slide downward along the sleeve shaft 8 due to gravity. When the penultimate sealing ring 9 completely falls to the upper end of the tapered rod, the two toggle teeth on the rear side and the two toggle teeth on the front side The penultimate sealing ring 9 will be clamped again, and the tip of the toggle tooth will enter the gap between the outer ends of every two sealing rings 9 again, so that the penultimate sealing ring 9 remains stationary, and the controller opens the two first telescopic rods 10, and the two first telescopic rods 10 push the corresponding pressing rings 11 to move downward, and the two pressing rings 11 jointly press the sealing ring 9 to slide downward along the tapered rod. Since the diameter of the upper end of the tapered rod is smaller than the diameter of the lower end, the sealing ring 9 will gradually become larger during the sliding process until the sealing ring 9 is slid into the sealing ring groove of the piston rod 13, thereby completing the automatic assembly of the sealing ring 9. In this way, the sealing ring 9 can be assembled continuously, which greatly improves the production efficiency and product quality, thereby standing out in the fierce market competition and winning more market share.

[0025] like Figure 4 , Fig. 9 , Figure 7 , Fig.14As shown, the blanking assembly includes a right bending rod 19, which is an "L"-shaped structure. The right bending rod 19 and the left bending rod 5 are symmetrically arranged on the left and right. A positioning ring 20 is fixedly installed on the top of the right bending rod 19, and the positioning ring 20 is arranged to pass through from top to bottom. A downwardly extending blanking barrel 21 is fixedly installed inside the positioning ring 20, and the blanking barrel 21 is arranged to pass through from top to bottom. The right end of the right bending rod 19 is fixedly installed with a built-in rod 22, and the built-in rod 22 is arranged on the left side of the blanking barrel 21. The right end of the built-in rod 22 is provided with a built-in hole that passes through from top to bottom, and a swing rod 23 is rotatably installed with the built-in hole. The top and bottom ends of the swing rod 23 are respectively provided with built-in grooves, a top rod 24 is fixedly installed in the upper built-in groove, and a bottom rod 25 is fixedly installed in the lower built-in groove, the top rod 24 and the bottom rod 25 are arranged parallel to each other, and an upper socket and a lower socket are provided at the left end of the blanking barrel 21. A top slide bar 26 is installed for right sliding movement, and a top plugging bar 27 is fixedly installed at the right end of the top slide bar 26. The right end of the top plugging bar 27 is slidably installed left and right in the upper socket, and the top slide bar 26 can provide a guiding and limiting effect for the top plugging bar 27. The left end of the top plugging bar 27 is provided with a first vertical slot 28, and the top rod 24 is slidably installed up and down in the first vertical slot 28. The lower end of the built-in rod 22 is slidably installed left and right with a bottom slide bar 29, and the bottom slide bar 29 is arranged on the right side of the top plugging bar 27, and a certain distance is reserved between the two. The right end of the bottom slide bar 29 is fixedly installed with a bottom plugging bar 30, and the right end of the bottom plugging bar 30 is slidably installed left and right in the lower socket, and the bottom slide bar 29 can provide a guiding and limiting effect for the bottom plugging bar 30. The left end of the bottom plugging bar 30 is provided with a second vertical slot 31, and the bottom rod 25 is slidably installed up and down in the second vertical slot 31, and the bottom slide bar 29 and the top slide bar 26 are curved structures respectively; The personnel rotates the swing rod 23, and the bottom plug rod 30 slides to the right into the lower barrel 21, while the top plug rod 27 slides to the left. The personnel place multiple piston rods 13 in the lower barrel 21, and the two bottom plug rods 30 block the penultimate piston rod 13 in the lower barrel 21, and the top plug rod 27 does not contact the penultimate piston rod 13; When the piston rod 13 is released, the swing rod 23 is rotated in the opposite direction, and the bottom plug rod 30 slides to the left until it is completely separated from the last piston rod 13. At the same time, the top plug rod 27 slides to the right to block the piston rod 13, and the piston rod 13 falls onto the positioning assembly, thereby completing the automatic falling of the piston rod 13. Then, the swing rod 23 is rotated in the opposite direction, the bottom plug rod 30 slides to the right into the discharge barrel 21, and the top plug rod 27 slides to the left and completely contacts the piston rod 13. Multiple piston rods 13 gradually slide downward, and the bottom plug rod 30 blocks the last piston rod 13. By repeating the above steps, the piston rod 13 can be released continuously and intermittently, which improves the automation rate and safety and reduces the physical strength of personnel to a certain extent.

[0026] like Figure 3 , Figure 8 As shown, a fixed cylinder 32 located in the placement box 2 is coaxially fixedly installed on the bottom end of the rotating disc 12, and the bottom end of the fixed cylinder 32 is rotatably installed on the placement box 2. A plurality of slot plates 33 are evenly fixedly installed on the circumferential wall of the lower end of the fixed cylinder 32, and a slot 34 is opened on the outer end of each of the slot plates 33. A first motor 35 is fixedly installed on the inner end of the placement box 2, and the first motor 35 is connected to a controller and a power supply. A circumferential rod 36 is coaxially fixedly installed on the rotating shaft of the first motor 35, and a toggle shaft 37 is fixedly installed on the other end of the circumferential rod 36. When the rotating disc 12 is rotated, the power is turned on, and the controller starts the first motor 35 to rotate. The shaft of the first motor 35 rotates with the circumferential rod 36 and the toggle shaft 37. The toggle shaft 37 enters the corresponding notch 34 and pushes the slot plate 33 to move. The fixed cylinder 32 rotates with the rotating disc 12 until the toggle shaft 37 is disengaged from the corresponding notch 34. The fixed cylinder 32 no longer rotates. During the rotation of the rotating disc 12, the positioning assembly is driven to rotate, and the position of each positioning assembly and the piston rod 13 is precisely controlled. Since the piston rod 13 rotates intermittently, the speed changes relatively smoothly, and no impact or vibration occurs, thereby ensuring the falling accuracy of the piston rod 13 and the sealing ring 9.

[0027] like Figure 3 , Figure 5 As shown, the positioning assembly includes a flip disk 38, and a plurality of flip openings 39 are evenly provided on the rotating disk 12, the number of the flip openings 39 is the same as the number of the slot plates 33, a positioning shaft is fixedly installed in each of the flip openings 39, a flip disk 38 is rotatably installed on each positioning shaft, and the flip disk 38 can rotate in the flip opening 39, a card slot is provided at the upper end of each flip opening 39, the card slot is arranged close to the center disk 4, a card plate is fixedly installed on each flip disk 38, under normal conditions, the card plate is arranged in the card slot, and the flip disk 38 can be limited, and each positioning shaft is sleeved with a torsion spring, one end of each torsion spring is fixedly connected to the flip disk 38, and the other end is fixedly connected to the self-rotating disk 12. On the rotating disc 12, a clamping ring 40 is fixedly installed on the top of each flip disc 38, a rear frame 47 is fixedly installed on the rear end of the left bending rod 5, and the rear frame 47 is fixedly connected to the right bending rod 19. A driving rod 48 is fixedly installed on the rear frame 47, and a third telescopic rod 49 is fixedly installed on the other end of the driving rod 48. The third telescopic rod 49 is an electric telescopic rod and is connected to a power supply and a controller. The telescopic rod of the third telescopic rod 49 is fixedly installed with a driving rack. A plurality of gear openings are evenly opened on the rotating disc 12, and a flip gear 50 located in the gear opening is coaxially fixedly installed on each positioning shaft, and the flip gear 50 is rotatably installed in the corresponding gear opening; The personnel take the piston rod 13 and place it in each clamping ring 40 between the right bending rod 19 and the left bending rod 5. The clamping ring 40 below the unloading barrel 21 does not have the piston rod 13, and the piston rod 13 below the sleeve shaft 8 has the piston rod 13 (the operation steps can also be adjusted as needed). Turn on the power, and the controller starts the two first telescopic rods 10. The two first telescopic rods 10 push the corresponding pressing rings 11 to move downward. The two pressing rings 11 jointly press the falling sealing ring 9 to slide downward along the tapered rod. Finally, the sealing ring 9 slides along the tapered rod into the sealing ring groove of the piston rod 13, thereby completing the assembly of the sealing ring 9. Then the controller starts the first motor 35 to rotate, the rotating shaft of the first motor 35 rotates with the circumferential rod 36 and the toggle shaft 37, the toggle shaft 37 enters the corresponding notch 34 and pushes the slot plate 33 to move, the fixed cylinder 32 rotates with the self-rotating disc 12 until the toggle shaft 37 is disengaged from the corresponding notch 34, the fixed cylinder 32 stops rotating, the self-rotating disc 12 rotates and drives the clamping ring 40 to rotate, the clamping ring 40 without the piston rod 13 is moved to the bottom of the discharge barrel 21, and the piston rod 13 without the sealing ring 9 is moved to the bottom of the sleeve shaft 8; When the installed piston rod 13 moves to the corresponding position of the third telescopic rod 49, the controller starts the third telescopic rod 49 to extend outward, and the driving rack meshes with the flip gear 50 to rotate in the flip opening 39, flipping the piston rod 13 into the placement box 2. At the same time, the torsion spring twists and accumulates force. Due to the gravity of the piston rod 13, it quickly slides from the retaining ring 40 to the placement box 2, thereby realizing the automatic falling of the piston rod 13. When the piston rod 13 falls, the controller starts the third telescopic rod 49 to contract, and the driving rack meshes with the flip gear 50 to rotate in the reverse direction in the flip opening 39. The torsion spring gradually recovers until the card plate moves into the card slot. At the same time, the driving rack disengages from the flip gear 50, thereby realizing automatic unloading and further improving work efficiency.

[0028] like Figure 4 , Figure 6 As shown, an external rod 41 is fixedly installed on the outer end of each pressing ring 11, and a rectangular groove 42 is opened on each external rod 41. A clamping block 43 is fixedly installed on the lower end of each first telescopic rod 10, and each clamping block 43 is slidably installed in the corresponding rectangular groove 42. A pressure spring 44 is provided in each rectangular groove 42, and one end of each pressure spring 44 is fixedly connected to the corresponding clamping block 43, and the other end is fixedly connected to the pressing ring 11; Turn on the power, and the controller starts the two first telescopic rods 10. The two first telescopic rods 10 push the corresponding pressing rings 11 to move downward. Since the diameter of the upper end of the tapered rod is smaller than the diameter of the lower end, the two pressing rings 11 will press the sealing ring 9 to slide downward along the corresponding blocking blocks 43 as they move away from each other.
