Description

Technical Field

[0001] This invention relates to the field of sealing technology, and more specifically, to a sealing assembly method and system. Background Technology

[0002] In the field of automated assembly of sealing components, existing technologies typically employ conveyor belts or similar conveying units to continuously transport sealing components (including sealing rings and pre-placed retaining rings) to the vicinity of the assembly station. A pushing mechanism then pushes the components to a designated waiting area for subsequent transfer by a handling unit to the processing position for press-fit assembly. Peripheral technologies involve various handling mechanisms, such as robotic arms or linear guide-driven gripping devices, utilizing pneumatic grippers or vacuum suction cups to grasp components from above or the side, thereby enabling component movement between different workstations. Furthermore, assembly systems often include multiple processing stations to progressively complete the press-fitting and fixing of the sealing rings and retaining rings, improving assembly efficiency and consistency.

[0003] However, in existing technologies, when pushing the sealing assembly to the waiting area, the circular or annular structure and high center of gravity of the assembly make it prone to shifting or slipping off the edge of the assembly table due to the inertia of the pushing force, especially at the moment before the transport unit is in place and clamped. This problem leads to production interruptions, component damage, or unstable assembly quality, increasing maintenance costs and scrap rates. Therefore, an improved sealing assembly method is needed that can reliably intercept and fix the assembly in the waiting area without adding complex structures, preventing slippage, and optimizing the transport process to improve overall assembly efficiency. Summary of the Invention

[0004] To address the problem of sealing components falling off during assembly, this invention provides a sealing component assembly method and system, comprising:

[0005] In a first aspect, the present invention provides a method for assembling a sealing assembly, comprising:

[0006] The conveying unit transports the sealing assembly to the pushing position, and the pushing unit pushes the sealing assembly toward the waiting area.

[0007] The second conveying unit is driven to swing from the outer periphery of the waiting area to approach and clamp the outer peripheral wall of the sealing assembly in the waiting area;

[0008] The second transport unit is driven to translate, moving the sealing assembly in the waiting area to the first processing area;

[0009] When the second handling unit leaves the first processing area and the first processing of the sealing component in the first processing area is completed, the first handling unit is driven to translate, thereby driving the sealing component in the first processing area to the second processing area; wherein, the translation of the second handling unit is synchronized with the translation of the first handling unit.

[0010] In some embodiments, the driving the second handling unit to swing close to and clamp the outer peripheral wall of the sealing component from the outer peripheral side of the sealing component in the waiting area includes:

[0011] Based on the alignment of a part of the second handling unit with the waiting area, the second handling long rod is driven to swing in the direction of clamping the sealing component, and the second handling short rod is driven to swing in a direction perpendicular to the feeding direction of the feeding unit;

[0012] The sealing component enters the range of the second handling long rod and the second handling short rod and reaches the to-be-clamped state; wherein, the to-be-clamped state includes that more than one-half of the projected area of the sealing component is located on the side of the end of the second handling long rod where the assembling component is located;

[0013] The second handling long rod swings in the direction of approaching the outer peripheral wall of the sealing component, and the second handling short rod swings in the direction of approaching the outer peripheral wall of the sealing component until the second handling long rod and the second handling short rod swing to abut against the outer peripheral wall of the sealing component.

[0014] In some embodiments, in the step of driving the second handling long rod to swing in the direction of clamping the sealing component and driving the second handling short rod to swing in a direction perpendicular to the feeding direction of the feeding unit based on the alignment of a part of the second handling unit with the waiting area, the driving the second handling short rod to swing in a direction perpendicular to the feeding direction of the feeding unit includes: the second handling short rod first swings away from the sealing component to be clamped, and after the second handling short rod reaches the waiting area, the second handling short rod swings to a direction perpendicular to the feeding direction of the feeding unit.

[0017] In some embodiments, the second long transport rod swings toward the outer peripheral wall of the sealing assembly, and the second short transport rod swings toward the outer peripheral wall of the sealing assembly until the second long transport rod and the second short transport rod swing to abut against the outer peripheral wall of the sealing assembly. The swinging of the second short transport rod toward the outer peripheral wall of the sealing assembly to be clamped includes the second short transport rod swinging toward the outer peripheral wall of the sealing assembly at a set angle.

[0018] In some embodiments, when the second transport unit leaves the first processing area and the first processing of the sealing assembly in the first processing area is completed, driving the first transport unit to translate and move the sealing assembly in the first processing area to the second processing area includes:

[0019] After the sealing component arrives at the first processing area, the assembly component performs the first processing on the sealing component;

[0020] After the sealing assembly completes the first processing in the first processing area, it drives the second transport unit to detach from the outer peripheral wall of the sealing assembly and move away from the first processing area to the next direction where the sealing assembly is to be clamped.

[0021] The first transport unit simultaneously moves toward the sealing assembly in the first processing area;

[0022] When the first transport unit arrives at the first processing area, it is driven to move closer to the sealing assembly until the first transport rod abuts against the outer peripheral wall of the sealing assembly.

[0023] The first transport unit is driven to move the sealing assembly of the first processing area to the second processing area.

[0024] In some embodiments, after the sealing assembly completes the first processing in the first processing area, in the step of driving the second transport unit to detach from the outer peripheral wall of the sealing assembly and move away from the first processing area to the next direction to clamp the sealing assembly, the movement of the second transport unit away from the first processing area to the next direction to clamp the sealing assembly includes the reduction of the distance between the end of the support plate near the conveying unit and the conveying unit and the conveying unit, which is greater than zero.

[0025] In a second aspect, the present invention provides a sealing component assembly system, wherein the sealing component assembly system is applied to any of the sealing component assembly methods in the first aspect, comprising:

[0026] Mounting rack;

[0027] A supply assembly; the supply assembly includes a conveying unit and a pushing unit; the pushing unit is connected to the conveying unit; the supply assembly is located on one side of the mounting frame; the supply assembly supplies materials for the assembly of the sealing assembly;

[0028] An assembly assembly includes an assembly unit, a testing unit, and a workbench; the workbench is connected to a mounting frame; the assembly unit is connected to the mounting frame; the assembly unit is located on a side close to the supply assembly; the testing unit is spaced apart from the assembly unit and connected to the mounting frame; the workbench is located at the bottom of the assembly unit and the testing unit.

[0032] To solve the problem of sealing components falling off during assembly, the present invention has the following advantages:

[0033] This invention achieves rapid and reliable circumferential clamping and transfer of sealing components in a slippery waiting area through the steps of a second transport unit swinging towards and clamping the component from the outer periphery, and the second transport unit translating synchronously with the first transport unit. This also ensures seamless connection with the transport actions at the next workstation. This effectively prevents the sealing component from slipping off the edge of the worktable in the waiting area due to inertia or unstable positioning, ensuring the continuity and stability of the assembly process. Ultimately, it solves the technical problems of production interruption, part damage, and decreased yield caused by component slippage in existing technologies, achieving significant results in improving assembly automation, ensuring production cycle time, and maintaining product quality.

[0044] In the field of mechanical seals, a sealing assembly 40, consisting of a sealing ring 41 and a pre-placed retaining ring 42, is typically transported to the workstation for assembly via a conveyor belt 111. However, due to the annular shape of the sealing assembly 40 and the presence of burrs causing instability in its center of gravity, the assembly is prone to shifting or even slipping off the edge of the workstation during the instant it is pushed from the feeding position to the waiting area. This problem directly leads to feeding failures, production interruptions, and potential component damage, severely restricting the efficiency and reliability of automated assembly lines. Therefore, there is an urgent need for an assembly method that can effectively prevent components from slipping during the initial transfer stage and ensure a smooth and stable process.

[0045] Example 1:

[0046] In this embodiment, the system applied to the sealing component assembly method, such as Figure 4As shown, it includes: mounting bracket 50, supply assembly 10, handling assembly 30, assembly assembly 20 and sealing assembly 40.

[0047] The supply assembly 10 is connected to the mounting frame 50 and is located on top of the mounting frame 50. Its conveying unit 11 includes a conveyor belt 111, rollers 112, a conveying drive unit 113, and a conveying bracket 114. The two ends of the conveyor belt 111 are respectively sleeved on two rollers 112. The conveying drive unit 113 is drivenly connected to the rollers 112. The conveying bracket 114 is arranged on both sides of the conveyor belt 111. The conveying drive unit 113 drives multiple rollers 112, which in turn drives the conveyor belt 111 to move on the conveying bracket 114, thereby conveying the sealing assembly 40 to the pushing position.

[0048] The pushing unit 12 includes a pushing drive unit 121 and a pushing head 122. The pushing head 122 is drivenly connected to the pushing drive unit 121. The pushing head 122 is located above the conveyor belt 111. The pushing drive unit 121 is connected to the conveyor bracket 114. Subsequently, the pushing drive unit 121 of the pushing unit 12 drives the pushing head 122 to push the sealing assembly 40 from the pushing position to the waiting area on the workbench 24.

[0049] The transport assembly 30 is connected by a drive unit 31, a support unit 32, a first transport unit 33, and a second transport unit 34. The drive unit 31 includes a first translation part 311 and a second translation part 312. The first translation part 311 and the second translation part 312 have the same structure and are symmetrically arranged on both sides of the worktable 24. The first translation part 311 and the second translation part 312 achieve overall synchronous translation. The support unit 32 includes a support plate 321, a first fixing groove 322, a second fixing groove 323, a first movable groove 324, and a second movable groove 325. Two support plates 321 are provided, which are respectively installed on the first translation part 311 and the second translation part 312. The support plate 321 of the support unit 32 serves as the installation base. Each support plate 321 is provided with a first fixing groove 322, a second fixing groove 323, a first movable groove 324, and a second movable groove 325. The first fixing groove 322 and the second fixing groove 323 are used to install the first transport unit 33. The first movable groove 324 and the second movable groove 325 are used to install the second transport unit 34.

[0050] The first transport unit 33 includes a first transport rod 331 and a first abutting ring 332; one end of each of the two first transport rods 331 is respectively disposed on a first fixing groove 322 and a second fixing groove 323, and the other end of each of the two first transport rods 331 is respectively disposed on a first abutting ring 332; the support plate 321 is provided with multiple sets of first fixing grooves 322 and second fixing grooves 323, and therefore multiple sets of first transport units 33 are provided accordingly.

[0051] The second transport unit 34 includes a second transport long rod 341 and a second transport short rod 344. One end of the second transport long rod 341 is movably mounted on a second movable groove 325, and one end of the second transport short rod 344 is movably mounted on a first movable groove 324. The second transport long rod 341 is controlled to swing by a long rod drive part 342 located at the bottom of the support plate 321. The other end of the second transport long rod 341 is provided with a second long rod abutment ring 343. The second transport short rod 344 is controlled to swing by a short rod drive part 345 located at the bottom of the support plate 321. The other end of the second transport short rod 344 is provided with a second short rod abutment ring 346. The second transport long rod 341 and the second transport short rod 344, by cooperating with the first movable groove 324 and the second movable groove 325 on the support plate 321, can swing together from the outer periphery of the sealing assembly 40 and finally use their respective abutment rings to stably clamp its outer peripheral wall.

[0052] To prevent the sealing assembly 40 from falling during its entry into the waiting area, the length of the second long transport rod 341 must be greater than the length of the second short transport rod 344 to intercept any falling sealing assembly 40. To prevent the sealing assembly 40 from sliding out of the waiting area due to inertia, the length of the second short transport rod 344 must be greater than the length of the first transport rod 331 to provide a barrier for the sealing assembly 40.

[0053] Assembly component 20 includes assembly bracket 21, assembly unit 22 and detection unit 23; assembly bracket 21 is mounted on top of mounting frame 50, and assembly unit 22 is driven by assembly drive unit 221 to press head 222 to perform pressing operation on sealing component 40 located on worktable 24. After pressing, sealing component 40 is moved from first processing area to second processing area by first transport unit 33, and detection unit 23 performs qualification test on the pressed sealing component 40.

[0054] like Figure 1 As shown, a method for assembling a sealing component 40 includes steps S10-S40.

[0055] In step S10, the sealing assembly 40 is conveyed to the pushing position by the conveying unit 11, and the pushing unit 12 pushes the sealing assembly 40 toward the waiting area. The conveying unit 11 delivers the sealing assembly 40 to the pushing position, and then the pushing unit 12 pushes it to the waiting area, achieving automated connection of continuous conveying of the sealing assembly 40 to a precisely positioned location. This not only lays the foundation for subsequent handling and processing, but more importantly, this step pre-places the sealing assembly 40 in a defined waiting area, creating the prerequisite for the subsequent second handling unit 34 to perform specific and targeted clamping actions, thus providing initial assurance for the accuracy and reliability of the entire process.

[0056] Step S20 involves driving the second transport unit 34 to swing from the outer periphery of the waiting area towards and clamp the outer peripheral wall of the sealing assembly 40 within the waiting area. Driving the second transport unit 34 to swing from the outer periphery of the sealing assembly 40 in the waiting area towards and clamp the outer peripheral wall constitutes the key to solving the core problem in this solution. By utilizing the swinging approach, the second transport unit 34 (especially its second transport rod 341) can quickly form an effective barrier the instant the sealing assembly 40 is pushed into the waiting area, achieving timely interception and circumferential clamping of the sealing assembly 40's edge. This directly solves the risk of the assembly slipping in the waiting area due to inertia or unstable position, ensuring the stability and safety of the assembly's posture before transfer.

[0057] In step S30, the second transport unit 34 is driven to translate, moving the sealing component 40 from the waiting area to the first processing area. By driving the second transport unit 34 to translate the sealing component 40 from the waiting area to the first processing area, the sealed component 40, which has been stably clamped, is safely and reliably transferred to the first assembly process. Based on the stable clamping state established in step S20, this translation process effectively avoids the component from shaking, shifting, or falling off during the movement, ensuring that the component can reach the first processing area with a precise orientation, providing a solid foundation for subsequent high-quality pressing assembly.

[0058] In step S40, the second transport unit 34 leaves the first processing area and the first processing of the sealing component 40 in the first processing area is completed. The first transport unit 33 is then driven to translate, moving the sealing component 40 from the first processing area to the second processing area. The translation of the second transport unit 34 is synchronized with the translation of the first transport unit 33. By setting the "second transport unit 34 leaving" and the "driving the first transport unit 33 to translate, moving the sealing component 40 to the second processing area" simultaneously, seamless connection and efficient flow of transport tasks between different workstations are achieved. This synchronous operation strategy allows the second transport unit 34 to immediately return to perform the next clamping task after unloading, while the first transport unit 33 simultaneously takes over the transport task at the next workstation. This significantly shortens the waiting time between processes, eliminates idle gaps in the transport process, and thus significantly improves the production cycle time and overall efficiency of the entire assembly system.

[0059] Specifically, such as Figure 2 As shown, step S20 includes steps S21 to S23.

[0060] Step S20, the driving of the second conveying unit 34 to swing from the outer peripheral side of the sealing assembly 40 in the waiting area to approach and clamp the outer peripheral wall of the sealing assembly 40 includes:

[0061] In step S21, based on the partial alignment of the second transport unit 34 with the waiting area, the second transport long rod 341 is driven to swing in the direction to clamp the sealing component 40, and the second transport short rod 344 is driven to swing in a direction perpendicular to the pushing direction of the pushing unit 12. Since the second transport unit 34 is partially aligned with the waiting area, the early swing of the second transport long rod 341 allows it to enter the possible movement path of the sealing component 40 as early as possible, forming a preliminary barrier and greatly enhancing the interception capability to prevent the sealing component 40 from accidentally slipping off. The swing of the second transport short rod 344 to a vertical state is equivalent to pre-blocking the sealing component 40 to prevent it from sliding out of the waiting area due to inertia. The second transport long rod 341 and the second transport short rod 344 together form a preliminary, open enclosure area, equivalent to pre-arranging grippers on both sides of the sealing component 40, laying the optimal spatial posture foundation for the next step of precise and efficient clamping.

[0062] In step S22, the sealing component 40 enters the range of the second transport long rod 341 and the second transport short rod 344, reaching the clamping state; wherein, the clamping state includes more than half of the projected area of ​​the sealing component 40 located on the side of the end of the second transport long rod 341 located in the assembly component 20; the quantitative requirement of the projected area of ​​the sealing component 40 ensures that the center of gravity has stably crossed the protective boundary of the second transport long rod 341, creating the optimal mechanical conditions for the subsequent closing and clamping of the second transport long rod 341, so that the sealing component 40 will not go out of bounds during the clamping process, greatly improving the stability and reliability of the transport process.

[0063] In step S23, the second long transport rod 341 swings towards the outer peripheral wall of the sealing assembly 40, and the second short transport rod 344 swings towards the outer peripheral wall of the sealing assembly 40, until the second long transport rod 341 and the second short transport rod 344 swing to abut against the outer peripheral wall of the sealing assembly 40. The combined motion of the active swinging and retraction of the second long transport rod 341 and the second short transport rod 344 allows the second transport unit 34 to approach and envelop the sealing assembly 40 from multiple directions in a gentle and precise manner. This avoids the overturning of the sealing assembly 40 that may be caused by a single rigid impact, ensuring the smoothness and controllability of the clamping process, and providing dynamic protection for the final stable and reliable clamping state. This multi-point circumferential contact abutment method can uniformly apply clamping force to the outer peripheral wall of the sealing assembly 40, forming a stable multi-point positioning. It not only effectively prevents the assembly from slipping during subsequent transport, but also avoids deformation or damage to the sealing ring 41 that may be caused by stress concentration at a single point, ultimately achieving safe, undamaged, and secure clamping of the sealing assembly 40.

[0064] Further, in the step of aligning the second handling unit 34 with the waiting area and driving the second handling long rod 341 to swing in the direction of clamping the sealing component 40 and driving the second handling short rod 344 to swing in a direction perpendicular to the feeding direction of the feeding unit 12, driving the second handling short rod 344 to swing in a direction perpendicular to the feeding direction of the feeding unit 12 includes: the second handling short rod 344 first swings away from the sealing component 40 to be clamped, and after the second handling short rod 344 reaches the waiting area, the second handling short rod 344 swings to a direction perpendicular to the feeding direction of the feeding unit 12.

[0065] The second handling short rod 344 swings outwards first to create space, avoiding collision with the outer peripheral wall of the sealing component 40 that has completed the first processing during subsequent repeated movements, and also clearing a safe path for subsequent actions, ensuring the reliability of the equipment operation; the second handling short rod 344 swings to a vertical state to effectively block the sealing component 40 in advance, preventing the sealing component 40 from sliding out of the waiting area due to inertia. Thus, while eliminating the risk of interference, it provides guarantee for accurately and stably clamping the component subsequently, improving the smoothness and success rate of the entire handling process.

[0066] Further, D1 < D; where D is the outer circumferential diameter of the sealing component 40; in the step of swinging the second handling long rod 341 in the direction of clamping the sealing component 40 to a set angle, D1 is the distance between the end of the second handling long rod 341 close to the sealing component 40 to be clamped and the side of the conveying unit 11 close to the workbench 24.

[0067] Ensure that after the second handling long rod 341 moves towards the sealing component 40, the end of the second handling long rod 341 can extend in front of the path where the sealing component 40 may slip, thus forming an effective interception in the physical space. When the sealing component 40 is pushed towards the waiting area, even if there is a tendency to slip due to factors such as inertia, it will be timely blocked by the end of the second handling long rod 341 that has been in place. This design upgrades the second handling long rod 341 from a simple clamping component to an机构 with a pre-protection function, preventing the risk of component dropping at the waiting station from the source through precise spatial layout, greatly improving the reliability and success rate of the feeding process.

[0068] Further, D2 < D; where D is the outer circumferential diameter of the sealing component 40; in the step of driving the second handling short rod 344 to swing in a direction perpendicular to the feeding direction of the feeding unit 12, D2 is the distance between the two second handling short rods 344 located on both sides of the sealing component 40.

[0069] When the second short transport rod 344 swings to a vertical position, the width of the channel formed between the two opposing second short transport rods 344 is naturally smaller than the diameter of the sealing assembly 40. This design allows the two short transport rods to form a physical limiting structure on both sides of the sealing assembly 40 before the final clamping action is performed. This effectively prevents the sealing assembly 40 from sliding out of the waiting area. This feature, combined with the end interception function of the second long transport rod 341, forms a three-dimensional protection mechanism that simultaneously constrains the sealing assembly 40 from the front and rear, significantly enhancing the positioning reliability of the sealing assembly 40 before the clamping action is performed, and fundamentally eliminating the risk of the sealing assembly 40 leaving the waiting area.

[0070] Further, the second long transport rod 341 swings toward the outer peripheral wall of the sealing assembly 40, and the second short transport rod 344 swings toward the outer peripheral wall of the sealing assembly 40, until the second long transport rod 341 and the second short transport rod 344 swing to abut against the outer peripheral wall of the sealing assembly 40. The swinging of the second short transport rod 344 toward the outer peripheral wall of the sealing assembly 40 to be clamped includes the second short transport rod 344 swinging toward the outer peripheral wall of the sealing assembly 40 at a set angle.

[0071] This ensures that the second transport rod 344 retracts and abuts against the sealing component 40 with the exact same trajectory and path each time, thereby precisely pushing and positioning the sealing component 40 at the preset center of the first processing area. This highly repeatable positioning action effectively eliminates the final positional deviation of the component caused by the randomness of the clamping posture, solves the alignment accuracy problem caused by the fixed and non-adjustable first and second processing areas, provides a stable positioning reference for subsequent assembly processes, and directly ensures the uniformity of processing quality and product yield in pressing and other processes.

[0072] Specifically, such as Figure 3 As shown, step S40 includes steps S41 to S45.

[0073] Step S40, where the second transport unit 34 leaves the first processing area and the first processing of the sealing assembly 40 in the first processing area is completed, driving the first transport unit 33 to translate and move the sealing assembly 40 in the first processing area to the second processing area includes:

[0074] In step S41, after the sealing component 40 arrives at the first processing area, the assembly component 20 performs the first processing on the sealing component 40; this establishes the logical premise between the two core processes of handling and processing. This ensures the accuracy and timeliness of the processing actions; the next process (assembly) will only start after the previous process (handling) is confirmed to be complete. This avoids the risk of misprocessing before the sealing component 40 is in place or interference with processing during handling, ensuring the independence of each workstation's operation and the rigor of the process.

[0075] In step S42, after the sealing assembly 40 completes the first processing in the first processing area, the driving unit 31 drives the second transport unit 34 to detach from the outer peripheral wall of the sealing assembly 40 and move away from the first processing area towards the next sealing assembly 40 to be clamped; this achieves a rapid functional switch for the second transport unit 34. Its beneficial effects are: on the one hand, the "detachment" action ensures that the second transport unit 34 can safely and without interference leave the processed assembly; on the other hand, it allows it to immediately move towards the next sealing assembly 40 to be clamped, aiming to fully utilize the idle time in the production cycle and pre-position for starting the next work cycle, which is a key step in improving the overall efficiency of the system.

[0076] In step S43, the first transport unit 33 simultaneously moves towards the sealing assembly 40 in the first processing area; "simultaneously" is the core of this step, and its beneficial effect is that it realizes the parallel operation of the two actions of "the second transport unit 34 leaving" and "the first transport unit 33 taking over" in time. This design eliminates the waiting intervals that exist in traditional sequential operations, greatly compresses the transfer time between processes, and provides a core guarantee for realizing continuous and efficient assembly line operations.

[0077] In step S44, when the first transport unit 33 arrives at the first processing area, the drive unit 31 drives the first transport unit 33 to approach the sealing assembly 40 until the first transport rod 331 abuts against the outer peripheral wall of the sealing assembly 40; this allows the first transport unit 33 to actively approach and establish a connection with the processed sealing assembly 40, forming a stable clamping action through "abutment." This flexible and targeted contact method effectively avoids impact or damage to the processed assembly, ensuring that the assembly is smoothly and safely taken over from a static state, preparing it for subsequent transfer.

[0078] Step S45: Drive the first transport unit 33 to move the sealing component 40 of the first processing area to the second processing area; the semi-finished products that have passed through the first processing area can be transported away from the current workstation in a timely and accurate manner and transported to the second processing area for detection by the detection unit 23, which also creates conditions for material discharge, thereby ensuring the continuity and integrity of the entire assembly process, which is the core link to realize multi-station, multi-process automated assembly.

[0079] Furthermore, in the step of driving the second transport unit 34 to detach from the outer peripheral wall of the sealing component 40 and move away from the first processing area to the next direction to clamp the sealing component 40 after the sealing component 40 completes the first processing area, the movement of the second transport unit 34 away from the first processing area to the next direction to clamp the sealing component 40 includes the reduction of the distance between the end of the support plate 321 near the conveying unit 11 and the conveying unit 11 and the conveying unit 11, which is greater than zero.

[0080] The support plate 321 does not need to contact the conveying unit 11 under the drive of the drive unit 31, because the swing of the second transport rod 341 prevents the sealing component 40 from falling. This solution not only saves kinetic energy, but also effectively prevents the transport component 30 from mechanically interfering with or colliding with the conveying unit 11, thus ensuring the safety and reliability of the equipment operation and avoiding downtime or component damage caused by collision.

[0082] In this embodiment, as Figure 4 As shown, the present invention provides a sealing component assembly system, comprising:

[0085] Assembly component 20; the assembly component 20 includes an assembly unit 22, a detection unit 23, and a workbench 24; the workbench 24 is connected to the mounting frame 50; the assembly unit 22 is connected to the mounting frame 50; the assembly unit 22 is located on the side close to the supply component 10; the detection unit 23 is spaced apart from the assembly unit 22 and connected to the mounting frame 50; the workbench 24 is located at the bottom of the assembly unit 22 and the detection unit 23.

[0086] A conveying assembly 30 includes a support unit 32, a first conveying unit 33, and a second conveying unit 34. The second conveying unit 34 is movably connected to the support unit 32. The first conveying unit 33 is connected to the support unit 32. The second conveying unit 34 is spaced apart from the first conveying unit 33 and is located on the side closer to the supply assembly 10. The second conveying unit 34 includes a second long conveying rod 341 and a second short conveying rod 344. The second long conveying rod 341 is movably connected to the support unit 32. The second short conveying rod 344 is movably connected to the support unit 32. The second long conveying rod 341 is located on the side closer to the supply assembly 10.

[0087] Sealing assembly 40; the sealing assembly 40 includes a sealing ring 41 and a retaining ring 42, the retaining ring 42 being embedded in the sealing ring 41.

[0088] The conveying unit 11 conveys the sealing assembly 40 to the pushing position; the pushing unit 12 pushes the sealing assembly 40 toward the waiting area; the second transporting long rod 341 and the second transporting short rod 344 of the second transporting unit 34 swing to approach and clamp the outer peripheral wall of the sealing assembly 40 in the waiting area; the sealing assembly 40 in the waiting area is transported to the first processing area; the assembly unit 22 presses the sealing assembly 40 to complete the first processing; after the first processing is completed, the sealing assembly 40 is translated and driven by the first transporting unit 33 to the second processing area; the detection unit 23 detects the sealing assembly 40 to complete the second processing.

[0089] This system organically integrates conveying, pushing, handling, and assembly functional modules into a unified, compact, and spatially defined automated workstation. Through strict positioning and connection relationships between components, it ensures precise connection and efficient coordination between the sealing assembly 40 (from conveying and pushing to handling) and the processing flow (assembly at the first and second workstations). This modular and integrated system design not only simplifies equipment installation and maintenance but, more importantly, enables continuous, stable, and automated assembly of the sealing assembly 40 (such as...). Figure 6 As shown, the sealing assembly 40 (including the sealing ring 41 and the retaining ring 42) provides a solid hardware foundation for the pressing, assembly, and testing process, thereby significantly improving the automation level, production efficiency, and process stability of the entire assembly operation.

The second movable slot 325 and the first movable slot 324 provide controllable degrees of freedom of movement for the second conveying long rod 341 and the short rod, respectively, enabling them to perform complex swinging clamping actions according to instructions. The second movable slot 325 is located on the outermost side closest to the supply assembly 10. This arrangement allows the second conveying long rod 341 to obtain the maximum range of motion and the optimal swing angle, thereby enabling effective interception from the side of the assembly's travel path at the first moment.
