Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, and specifically to an automatic assembly device for miniature sealing rings. Background Technology

[0002] In existing assembly processes involving sealing rings and electrode rivets, the sealing rings are small in size, typically with an inner diameter of 1.8-1.9 mm and a wall thickness of 0.8 mm. These are referred to as micro-sealing rings. Due to their extremely small size and thin wall, the clamping jaws of the mating fixtures are also very thin. This often leads to fixture breakage during the sealing ring clamping process. Furthermore, in existing technologies, the clamping jaws of the sealing ring clamps are often unable to accurately enter the sealing ring for precise clamping, which affects the overall assembly efficiency. Additionally, in existing technologies, electrode rivets are usually placed upside down on the guide rail during assembly, requiring straightening after clamping, which increases the assembly steps and reduces efficiency. Summary of the Invention

[0003] In view of this, the present invention provides an automatic assembly device for miniature sealing rings.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0009] Preferably, a transition transfer mechanism is provided on one side of the sealing ring feeding mechanism. The transition transfer mechanism includes a transfer storage base, and a temporary storage groove is provided at the top of the transfer storage base. The temporary storage groove is arranged in a cross structure, and four temporary storage sliders are provided in the temporary storage groove. Each temporary storage slider has a sealing ring storage part, and the sealing ring storage parts are combined to form a sealing ring storage end. The sealing ring is sleeved on the sealing ring storage end by a feeding assembly mechanism. The feeding assembly mechanism is provided with a picking end corresponding to the sealing ring storage end, and the sealing ring is transferred to the picking end through the sealing ring storage end.

[0010] Preferably, the electrode rivet feeding device includes a rivet vibratory feeder, a rivet linear feeder, a rivet pushing mechanism, and a rivet clamping mechanism. The electrode rivet is disposed in the rivet vibratory feeder. The electrode rivet is sequentially conveyed to the rivet pushing mechanism via the rivet vibratory feeder and the rivet linear feeder. The rivet clamping mechanism clamps the electrode rivet on the rivet pushing mechanism and conveys it to the assembly turntable.

[0011] Preferably, the rivet linear feeder is provided with a rivet slide rail, the rivet slide rail has a rivet limiting groove, the electrode rivet has a limiting ring groove, the portion of the electrode rivet located at the lower part of the limiting ring groove extends into the rivet limiting groove and connects with the rivet slide rail, the top two sides of the rivet slide rail are bent towards the center of the rivet limiting groove to form a limiting part, the limiting part extends into the limiting ring groove and connects with the electrode rivet, and the rivet linear feeder drives the electrode rivet to move on the rivet slide rail.

[0012] Preferably, the rivet pushing mechanism includes a fixed base, an upper pushing unit, and a lower pushing unit. A lower slide rail is provided on the fixed base, and the lower pushing unit is movably mounted on the lower slide rail. The lower pushing unit includes a pushing mounting seat and a lower pushing cylinder. One end of the lower pushing cylinder is connected to the pushing mounting seat, driving the pushing mounting seat to move on the lower slide rail. A pushing groove is formed at the top of the pushing mounting seat. One end of the upper pushing unit extends into the pushing groove and connects to the pushing mounting seat, and the upper pushing unit moves within the pushing groove. The upper pushing unit includes an upper slider and an upper pushing cylinder disposed within the pushing groove. The upper slider is movably disposed within the pushing groove, and a material distribution plate is provided on the upper slider. One side of the material distribution plate extends into a limiting ring groove, driving the electrode rivet to move.

[0013] Preferably, the rivet gripper mechanism includes a rivet gripper, a gripper lifting unit, and a gripper rotating unit. The rivet gripper is fixed on the gripper rotating unit.

The limiting block is arranged on the lifting sliding plate. Corresponding limiting holes are opened on the limiting block and the lifting slide rail plate. Limiting pins are provided in the limiting holes. The limiting pins limit and fix the position of the lifting sliding plate on the lifting slide rail. The gripper rotating unit is rotatably arranged on the lifting sliding plate.

[0014] Preferably, the transfer steps of the sealing ring in the lifting and transferring assembly are as follows:

[0015] Step 1: The sealing ring enters the sealing ring positioning seat under the drive of the sealing ring feeding mechanism. At this time, the top rod in the lifting and transmitting assembly rises and passes through the sealing ring, so that the sealing ring is sleeved on the top rod. The clamping and limiting assembly limits the upper and lower positions of the sealing ring. At this time, the transmitting component is in the initial position. The transmitting component in the initial position will not interfere with the sealing ring entering the sealing ring positioning seat.

[0016] Step 2: The pressing connection end of the feeding assembly mechanism moves down, applying pressure to the guide component towards the push rod, so that the guide component connects with the push rod. After the guide component connects with the push rod, the cylinder drives the push rod to move down, and the guide component continues to receive pressure and move towards the push rod. At this time, the sealing ring is limited in its vertical position, so it is fitted onto the bottom end of the guide component connected to the push rod during the downward movement of the push rod and the guide component. After the sealing ring is fitted onto the guide component, the feeding assembly mechanism returns to its original position.

[0017] Step 3: The clamping block in the clamping limit assembly is driven by the clamping cylinder to move away from the center of the sealing ring, and the push rod rises under the drive of the cylinder. During the rise of the push rod, the transmission component rises. At this time, the position of the sealing ring on the transmission component remains unchanged.

[0018] Step 4: After the transmission component has risen, the clamping block returns to its original position. At this time, the push rod descends, and the pressing connection end on the feeding assembly mechanism moves down again to apply pressure to the transmission component, causing the transmission component to move towards the push rod. During the descent of the push rod, the bottom of the sealing ring is limited by the clamping block, so that during the descent of the transmission component, it rises from the bottom end of the transmission component to the cylindrical part of the transmission component.

[0019] Step 5: The clamping connection end of the feeding mechanism moves down to the top of the transmission component. At this time, the sealing ring moves from the cylindrical part of the transmission component to the clamping connection end and is clamped as the transmission component moves down.

[0020] The beneficial effects of this invention are as follows: by setting up a sealing ring feeding and assembly device and an electrode rivet feeding device, this design can realize the automation of sealing ring feeding and assembly, reduce labor costs, and improve assembly efficiency.

[0039] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] The present invention will now be further described with reference to the accompanying drawings.

[0041] This invention provides the following technical solution:

[0042] As attached Figure 1-17As shown, this invention discloses an automatic assembly device for miniature sealing rings, including a base 1. A sealing ring feeding and assembly device 2 and an electrode rivet feeding device 3 are mounted on the base 1. An assembly turntable 4 is disposed between the sealing ring feeding and assembly device 2 and the electrode rivet feeding device 3. The sealing ring feeding and assembly device 2 includes a sealing ring feeding mechanism 5 and a feeding assembly mechanism 6. A sealing ring 7 and an electrode rivet 8 are respectively mounted on the sealing ring feeding mechanism 5 and the electrode rivet feeding device 3. The electrode rivet 8 is transported to the assembly turntable 4 by the electrode rivet feeding device 3. The sealing ring feeding mechanism 5 has a limiting transmission unit 9. The sealing ring 7 is transported to the limiting transmission unit 9 through the sealing ring feeding mechanism 5 and then transmitted to the feeding assembly mechanism 6 through the limiting transmission unit 9. The feeding assembly mechanism 6 transports the sealing ring 7 to the assembly turntable 4 for assembly with the electrode rivet 8. Specifically, in this design, by setting up a sealing ring feeding and assembly device 2 and an electrode rivet feeding device 3, the feeding and assembly of this miniature sealing ring can be automated, which solves the defect in the prior art that the miniature sealing ring cannot be automatically fed and assembled due to its small size and thin wall, reduces labor costs, and greatly improves assembly efficiency.

[0043] In the initial state, the sealing ring 7 is conveyed to the sealing ring installation station 26 inside the sealing ring positioning seat 12 via a vibratory feeder. The push rod rises and passes through the sealing ring, so that the sealing ring is fitted onto the push rod. Then, the pressing connection end 14 presses down, causing the transmission component 18 to move downward. The sealing ring moves along the push rod onto the transmission component 18, and the sealing ring 7 is fitted onto the transmission component body 21. Then, the clamping block 23 is pulled open. The push rod on the cylinder 16 has a transmission part 90, which drives the transmission component 18 to rise. At this time, the sealing ring... The ring position remains unchanged. Then, the clamping block 23 returns to limit the sealing ring 7. The pressing connection end 14 applies pressure to the conductor 18 again, causing it to move down again. The sealing ring 7 moves onto the cylindrical part 19. Then, the pressing connection end 14 presses the top of the cylindrical part 19. As the conductor 18 continues to move down, the sealing ring 7 moves onto the pressing connection end 14. Driven by the pressing connection end 14, it moves to the transition transfer mechanism 27 and is then transported by the transition transfer mechanism 27 to the assembly turntable for assembly with the electrode rivets.

[0044] Specifically, in this embodiment, the conductor is clamped by the limiting clamp assembly 10 during the descent process, and the two are tightly fitted together.

[0045] Furthermore, the limiting and transferring unit 9 includes a limiting clamp assembly 10 and a lifting and transferring assembly 11. The lifting and transferring assembly 11 is movably mounted on the base 1. A sealing ring positioning seat 12 is provided between the limiting clamp assembly 10 and the lifting and transferring assembly 11. The sealing ring feeding mechanism 5 conveys the sealing ring 7 to the sealing ring positioning seat 12. The lifting and transferring assembly 11 has a lifting connecting end 13, which penetrates the sealing ring positioning seat 12 and the sealing ring 7 on the sealing ring positioning seat 12. The limiting clamp assembly 10 limits and fixes the sealing ring 7 on the sealing ring positioning seat 12. The feeding and assembly mechanism 6 has a pressing connecting end 14. During the descent of the lifting and transferring assembly 11, the sealing ring 7 moves along the lifting connecting end 13 to the pressing connecting end 14. Specifically, in this embodiment, the lifting and transferring component 11 in the limiting and transferring unit 9 can pass through the sealing ring positioning seat 12 and the sealing ring 7 sequentially from bottom to top after the sealing ring 7 is positioned on the sealing ring positioning seat 12, so that the sealing ring 7 is fitted on the lifting and transferring component 11. Then, the limiting clamping component 10 clamps and fixes the sealing ring 7 towards the center of the sealing ring 7. After the sealing ring 7 is clamped and fixed, the pressing connection end 14 on the feeding assembly mechanism 6 presses down onto the lifting and transferring component 11. After the pressing connection end 14 contacts the lifting and transferring component 11, the pressing connection end 14 and the lifting and transferring component 11 continue to move down, so that the sealing ring 7 that is limited and clamped moves along the lifting and transferring component 11 to the pressing connection end 14, thereby realizing the transfer of the sealing ring 7. This process does not require manual movement of the sealing ring 7, which improves the efficiency of the transfer of the sealing ring 7. In addition, the size of the pressing connection end 14 in this embodiment is set to correspond to the inner diameter of the sealing ring 7, so that the sealing ring 7 will not fall off during subsequent transportation after it is transferred to the pressing connection end 14.

[0046] Furthermore, the lifting and transmitting assembly 11 includes a support frame 15, a cylinder 16, and a push rod 17. The sealing ring positioning seat 12 is located at the top of the support frame 15, the cylinder 16 is located at the bottom of the support frame 15, and the lifting connecting end 13 is located on the push rod 17. The end of the push rod 17 away from the sealing ring 7 is connected to the cylinder 16. A conductor 18 is provided between the push rod 17 and the pressing connecting end 14. The bottom end of the conductor 18 is connected to the lifting connecting end 13 of the push rod 17. A cylindrical part 19 and a frustum-shaped part 20 are arranged sequentially from top to bottom on the side of the conductor 18 away from the lifting connecting end 13. The sealing ring 7 moves to the conductor 18 through the lifting connecting end 13. As the sealing ring 7 moves along the conductor 18 toward the pressing connecting end 14, the inner diameter of the sealing ring 7 expands. Specifically, in this embodiment, the cylinder 16 fixed to the lower part of the support frame 15 can drive the push rod 17 to pass through the sealing ring positioning seat 12 to achieve lifting and lowering movement. The top end of the push rod 17 is provided with a conical groove 82 for connecting the transmission member 18. The transmission member 18 is provided with a conical end 81 corresponding to the conical groove 82. The conical end 81 extends into the conical groove 82 to achieve connection with the push rod 17. This structural arrangement can facilitate the concentric positioning of the transmission member 18 and the push rod 17. After the push rod 17 is connected to the transmission member 18, it drives the transmission member 18 to move vertically. During the lifting and lowering motion, the top of the conductor 18 contacts the pressing connection end 14. As the push rod 17 descends, the sealing ring 7 passes sequentially through the push rod 17, the conductor body 21, the frustum portion 20 of the conductor 18, and the cylindrical portion 19 of the conductor 18. During this passage through the frustum portion 20, the inner diameter of the sealing ring 7 gradually expands to match the outer diameter of the cylindrical portion 19. Subsequently, the sealing ring 7 is fitted onto the pressing connection end 14, whose outer diameter is smaller than that of the cylindrical portion 19 but larger than its initial inner diameter, thus achieving the transfer of the sealing ring 7. During this transfer process, the sealing ring 7 deforms. During this deformation, the outer diameter of the sealing ring 7 gradually and uniformly expands, preventing permanent deformation caused by a particularly prominent bulge in any direction, which could damage the sealing ring 7.

[0047] Furthermore, the limiting clamp assembly 10 includes a mounting block 22, a clamping block 23, and a clamping cylinder 24. The mounting block 22 covers the sealing ring positioning seat 12, and a clamping groove 25 corresponding to the clamping block 23 is formed on the mounting block 22. One end of the clamping block 23 extends into the clamping groove 25 to clamp the sealing ring 7 on the sealing ring positioning seat 12. One end of the clamping cylinder 24 is connected to the clamping block 23, which drives the clamping block 23 to move within the clamping groove 25. Specifically, in this embodiment, a sealing ring installation station 26 is formed by an inward recess on the sealing ring positioning seat 12. The sealing ring 7 is set in the sealing ring installation station 26. The push rod 17 is set through the sealing ring installation station 26. The clamping block 23 in the limiting clamp assembly 10 has one end away from the clamping cylinder 24 pressing against the push rod 17 and the transmission member 18 connected to the push rod 17. The bottom of the clamping block 23 presses against the sealing ring 7, so that the sealing ring 7 is close to the push rod 17 during the downward movement of the push rod 17. At the same time, the clamping block 23 can also limit the transmission member 18 to prevent the transmission member 18 from tilting and causing the sealing ring 7 to be unable to move.

[0048] Furthermore, a transition transfer mechanism 27 is provided on one side of the sealing ring feeding mechanism 5. The transition transfer mechanism 27 includes a transfer temporary storage base 28. A temporary storage groove 29 is opened at the top of the transfer temporary storage base 28. The temporary storage groove 29 is arranged in a cross structure. Four temporary storage sliders 30 are provided in the temporary storage groove 29. Each temporary storage slider 30 has a sealing ring temporary storage part 53. The sealing ring temporary storage parts 53 are combined to form a sealing ring temporary storage end 31. The sealing ring 7 is sleeved on the sealing ring temporary storage end 31 through the feeding assembly mechanism 6. The feeding assembly mechanism is provided with a picking end 32 corresponding to the sealing ring temporary storage end 31. The sealing ring 7 is transferred to the picking end 32 through the sealing ring temporary storage end 31. Specifically, in this embodiment, a transition transfer mechanism 27 is provided between the sealing ring feeding mechanism 5 and the assembly turntable 4 to temporarily store the sealing ring 7. When the sealing ring feeding mechanism 5 starts operating, the first sealing ring 7 that arrives at the sealing ring positioning seat 12 is driven by the pressing connection end 14 of the feeding assembly unit to move towards the transfer temporary storage base 28. At this time, the four temporary storage sliders 30 on the transfer temporary storage base 28 gradually close towards the center, so that the sealing ring temporary storage parts 53 on the temporary storage sliders 30 merge to form the sealing ring temporary storage end 31. Then the first sealing ring 7 is transferred to the sealing ring temporary storage end 31, while the second sealing ring 7 is transported to the sealing ring positioning seat 12 by the sealing ring feeding mechanism 5. Then the feeding assembly mechanism 6 starts again, and the sealing ring 7 is transported to the sealing ring positioning seat 12. The pressing connection end 14 and the picking end 32 on the material assembly mechanism 6 operate synchronously. The picking end 32 transfers the first sealing ring 7 on the sealing ring storage end 31 to the assembly turntable 4 and connects and fixes it with the electrode rivet 8. During this process, the pressing connection end 14 transfers the second sealing ring 7 on the sealing positioning seat to the sealing ring storage end 31. Repeating this process can improve the efficiency of the sealing ring 7 transfer and assembly, and avoid the risk of the sealing ring 7 falling off during the long distance of the sealing ring 7 being directly transferred from the sealing ring positioning seat 12 to the assembly turntable 4. It can also achieve synchronous operation of the sealing ring 7 and the electrode rivet 8. That is, when the sealing ring 7 is transferred to the assembly turntable, the electrode rivet 8 on the assembly turntable 4 rotates to the position of the corresponding sealing ring 7 to achieve precise assembly.

[0049] Specifically, in this embodiment, the feeding assembly mechanism 6 consists of a support shaft 33, a fixed plate 34, a horizontal moving assembly 35, and a longitudinal moving assembly 36. The support shaft 33 is vertically mounted on the base 1, and the fixed plate 34 is mounted on one side of the upper part of the support shaft 33. The horizontal moving assembly 35 includes a horizontal moving plate 37, a horizontal moving slider 38, and a horizontal guide rail 39. The horizontal guide rail 39 is mounted on the fixed plate 34. The two ends of the horizontal moving slider 38 are respectively connected to the horizontal guide rail 39 and the horizontal moving plate 37. A horizontal moving cylinder 40 is mounted on one side of the horizontal moving plate 37, and the horizontal moving cylinder 40 drives the horizontal movement. Plate 37 moves on horizontal guide rail 39 via slider. Longitudinal moving assembly 36 is mounted on horizontal moving plate 37. Longitudinal moving assembly 36 includes longitudinal moving cylinder 41, longitudinal moving plate 42, and feeding mounting plate 43. Longitudinal moving cylinder 41 is mounted on horizontal moving plate 37 and has a longitudinal cylinder 16 push rod. One end of the longitudinal cylinder 16 push rod is connected to the L-shaped longitudinal moving plate 42, driving the longitudinal moving plate 42 to move up and down. Feeding mounting plate 43 is fixed on longitudinal moving plate 42 and has a clamping connection part 44 for mounting clamping connection end 14 and a mounting bracket. The material handling assembly 45 at the material end 32 consists of a material handling cylinder 46, a material handling positioning block 47, and a material handling sleeve 48. The bottom end of the material handling cylinder push rod 49 of the material handling cylinder 46 is connected to the cylinder 46, and a connecting block 50 is installed on its top end. A positioning block connecting guide rod 51 is installed on one side of the connecting block 50. Both ends of the connecting block 50 are connected to the top end of the material handling cylinder push rod 49 and the positioning block connecting guide rod 51, respectively. The other end of the positioning block connecting guide rod 51 is connected to the material handling positioning block 47. The material handling sleeve 48 is mounted on the material handling positioning block 47. The material handling cylinder 46 drives the material handling sleeve 48 through the material handling positioning block 47 to achieve… The lifting action is performed, and the material picking end 32 is located at the bottom end of the material picking sleeve 48. The material picking end 32 is provided with a temporary storage outlet 52 corresponding to the temporary storage part 53 of the sealing ring. When the material picking end 32 needs to transfer the sealing ring 7 on the temporary storage end 31, the four temporary storage parts 53 move simultaneously away from the center of the temporary storage end, so that the inner diameter of the sealing ring 7 expands. At this time, the material picking end 32 extends into the sealing ring 7 so that the sealing ring 7 is fitted on the material picking end 32. Then the four temporary storage parts move closer to the center of the temporary storage end again, so that the temporary storage parts are completely separated from the sealing ring 7. Finally, the material picking end 32 rises and leaves the transition transfer mechanism 27.

[0050] Specifically, in this embodiment, the structure of the pressing connection end 14 is similar to that of the material taking end 32. The pressing connection end 14 has four openings for the movement of the sealing ring temporary storage part 53. When the pressing connection end 14 moves to the top of the sealing ring temporary storage end 31, the sealing ring temporary storage end 31 extends into the center of the pressing connection end 14. Then the sealing ring temporary storage part 53 moves outward to open the sealing ring 7. After opening the sealing ring 7, the pressing connection end 14 moves upward away from the sealing ring 7.

[0051] Furthermore, the electrode rivet feeding device 3 includes a rivet vibratory feeder 54, a rivet linear feeder 55, a rivet pushing mechanism 56, and a rivet gripper mechanism 57. The electrode rivet 8 is disposed in the rivet vibratory feeder 54. The electrode rivet 8 is sequentially conveyed to the rivet pushing mechanism 56 via the rivet vibratory feeder 54 and the rivet linear feeder 55. The rivet gripper mechanism 57 clamps the electrode rivet 8 on the rivet pushing mechanism 56 and conveys it to the assembly turntable 4. The rivet linear feeder 55 is equipped with a rivet slide. The rivet slide rail 58 has a rivet limiting groove 59, and the electrode rivet 8 has a limiting ring groove 60. The portion of the electrode rivet 8 located at the lower part of the limiting ring groove 60 extends into the rivet limiting groove 59 and connects with the rivet slide rail 58. The top two sides of the rivet slide rail 58 are bent towards the center of the rivet limiting groove 59 to form a limiting part 61. The limiting part 61 extends into the limiting ring groove 60 and connects with the electrode rivet 8. The rivet linear feeder 55 drives the electrode rivet 8 to move on the rivet slide rail 58. Specifically, in this embodiment, the electrode rivets 8 are all arranged vertically on the rivet slide rail 58, and the limiting part 61 on the rivet slide rail 58 cooperates with the limiting ring groove 60 of the electrode rivet 8 to prevent the electrode rivets 8 from tipping over during transportation. The vertical state of the electrode rivets 8 can reduce the process of straightening the electrode rivets 8 when they are subsequently clamped and fixed on the assembly turntable 4, thereby improving the assembly efficiency.

[0052] Furthermore, the rivet pushing mechanism 56 includes a fixed base 62, an upper pushing unit 63, and a lower pushing unit 64. A lower sliding rail 65 is provided on the fixed base 62, and the lower pushing unit 64 is movably mounted on the lower sliding rail 65. The lower pushing unit 64 includes a pushing mounting base 66 and a lower pushing cylinder 67. One end of the lower pushing cylinder 67 is connected to the pushing mounting base 66, driving the pushing mounting base 66 to move on the lower sliding rail 65. A pushing mechanism is provided at the top of the pushing mounting base 66. The upper pushing unit 63 extends into the pushing chute 68 and connects to the pushing mounting base 66. The upper pushing unit 63 moves within the pushing chute 68. The upper pushing unit 63 includes an upper sliding block 69 and an upper pushing cylinder 70 disposed within the pushing chute 68. The upper sliding block 69 is movably disposed within the pushing chute 68, and a material distribution plate 71 is disposed on the upper sliding block 69. One side of the material distribution plate 71 extends into the limiting ring groove 60, driving the electrode rivet 8 to move. Specifically, in this embodiment, both the upper pushing unit 63 and the lower pushing unit 64 can push the electrode rivet 8, thereby preventing the electrode rivet 8 from being unable to be pushed if one part is damaged.

[0053] Furthermore, the rivet gripper mechanism 57 includes a rivet gripper 72, a gripper lifting unit 73, and a gripper rotating unit 74.

The gripper lifting unit 73 includes a lifting slide rail plate 76, a lifting slide rail 75, a lifting sliding plate 77, and a limiting block 78. The lifting slide rail 75 is vertically arranged on one side of the lifting slide rail plate 76. The lifting sliding plate 77 is movably arranged on the lifting slide rail 75.

The gripper rotating unit 74 is rotatably arranged on the lifting sliding plate 77.

[0054] Furthermore, the gripper rotation unit 74 is a rotary cylinder mounted on the lifting sliding plate 77, and the rivet gripper 72 is a thumb cylinder fixed on the rotary cylinder. Therefore, the principles of the rotary cylinder and the thumb cylinder will not be described in detail here.

[0055] Specifically, in this design, an electrode rivet positioning structure is provided on the assembly turntable 4. The electrode rivet positioning structure includes a rivet positioning hole 83 and a rivet positioning assembly on the assembly turntable 4. The bottom end of the electrode rivet extends into the rivet positioning hole 83 and connects to the assembly turntable 4. A through hole 84 is provided on the side of the rivet positioning hole 83 away from the center of the assembly turntable, communicating with the rivet positioning hole. One end of the rivet positioning assembly is disposed in the through hole 84. The rivet positioning assembly includes a rivet push rod 85 and a push rod guide block 86.

The two ends of the spring 88 are respectively connected to the rivet top rod 85 and the rivet guide block 86. A pusher 89 is provided on the side of the rivet top rod 85 away from the assembly turntable 4. The pusher 89 drives the rivet top rod 85 to move and abut against the electrode rivet, thereby positioning the electrode rivet on the assembly turntable 4. The spring 88 is provided to facilitate the return of the rivet top rod after the pusher 89 is released.

[0056] Specifically, the transfer steps of the sealing ring in the lifting and transferring assembly are as follows:

[0057] Step 1: The sealing ring 7 enters the sealing ring positioning seat 12 under the drive of the sealing ring feeding mechanism. At this time, the top rod 17 in the lifting and transmitting assembly 11 rises and passes through the sealing ring 7, so that the sealing ring 7 is sleeved on the top rod 17. The clamp limiting assembly 10 limits the upper and lower positions of the sealing ring 7. At this time, the transmission member 18 is in the initial position. The transmission member 18 in the initial position will not interfere with the sealing ring 7 entering the sealing ring positioning seat 12.

[0058] Step 2: The pressing connection end 14 of the feeding assembly mechanism moves down, applying pressure to the guide member 18 towards the push rod 17, so that the guide member 18 connects with the push rod 17. After the guide member 18 connects with the push rod 17, the cylinder 16 drives the push rod 17 to move down, and the guide member 18 continues to receive pressure and move towards the push rod. At this time, the sealing ring 7 is limited in its vertical position, so it is sleeved on the bottom end of the guide member 18 connected with the push rod 17 during the downward movement of the push rod 17 and the guide member 18. After the sealing ring 7 is sleeved on the guide member 18, the feeding assembly mechanism returns to its original position.

[0059] Step 3: The clamping block 23 in the clamping limit assembly is driven by the clamping cylinder 24 to move away from the center of the sealing ring, and the push rod 17 rises under the drive of the cylinder 16. During the rise of the push rod 17, the transmission component 18 rises. At this time, the position of the sealing ring 8 on the transmission component 18 remains unchanged.

[0060] Step 4: After the transmission component 18 has risen, the clamping block 23 returns to its original position. At this time, the push rod 17 descends, and the pressing connection end 14 on the feeding assembly mechanism moves down again to apply pressure to the transmission component 18, causing the transmission component 18 to move towards the push rod 17. During the descent of the push rod 17, the bottom of the sealing ring 7 is limited by the clamping block 23, so that during the descent of the transmission component 18, it rises from the bottom end of the transmission component 18 to the cylindrical part 19 of the transmission component 18.

[0061] Step 5: The pressing connection end 14 of the feeding mechanism moves down to the top of the transmission member 18. At this time, the sealing ring 7 moves from the cylindrical part 19 of the transmission member 18 to the pressing connection end 14 and is clamped as the transmission member 18 moves down.
