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.

[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 comprises: a mounting frame 50, a feeding assembly 10, a carrying assembly 30, an assembling assembly 20 and a sealing assembly 40.

[0047] The feeding assembly 10 is connected with the mounting frame 50, and the feeding assembly 10 is located on the top of the mounting frame 50. The conveying unit 11 of the feeding assembly 10 comprises a conveying belt 111, rollers 112, a conveying driving part 113 and a conveying support 114. The two ends of the conveying belt 111 are sleeved on the two rollers 112 respectively. The conveying driving part 113 is drivingly connected with the rollers 112. The conveying support 114 is arranged on the two sides of the conveying belt 111. The plurality of rollers 112 is driven by the conveying driving part 113 to drive the conveying belt 111 to move on the conveying support 114, so as to convey the sealing assembly 40 to the pushing position.

[0048] The pushing unit 12 comprises a pushing driving part 121 and a pushing head 122. The pushing head 122 is drivingly connected with the pushing driving part 121. The pushing head 122 is located above the conveying belt 111. The pushing driving part 121 is connected with the conveying support 114. Then, the pushing driving part 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 carrying assembly 30 comprises a driving unit 31, a supporting unit 32, a first carrying unit 33 and a second carrying unit 34. The driving unit 31 comprises a first translation part 311 and a second translation part 312. The first translation part 311 and the second translation part 312 are the same in structure and are symmetrically arranged on the two sides of the workbench 24. The first translation part 311 and the second translation part 312 realize overall synchronous translation. The supporting unit 32 comprises a supporting plate 321, a first fixed groove 322, a second fixed groove 323, a first movable groove 324 and a second movable groove 325. Two supporting plates 321 are arranged on the first translation part 311 and the second translation part 312 respectively. The supporting plate 321 of the supporting unit 32 serves as a mounting base. The first fixed groove 322, the second fixed groove 323, the first movable groove 324 and the second movable groove 325 are arranged on each supporting plate 321. The first fixed groove 322 and the second fixed groove 323 are used for mounting the first carrying unit 33. The first movable groove 324 and the second movable groove 325 are used for mounting the second carrying unit 34.

[0050] The first carrying unit 33 comprises a first carrying rod 331 and a first abutting ring 332. One end of each of the two first carrying rods 331 is arranged on the first fixed groove 322 and the second fixed groove 323 respectively. The other end of each of the two first carrying rods 331 is arranged with the first abutting ring 332. A plurality of groups of the first fixed groove 322 and the second fixed groove 323 are arranged on the supporting plate 321, so that a plurality of groups of the first carrying unit 33 are correspondingly arranged.

[0051] The second carrying unit 34 comprises a second carrying long rod 341 and a second carrying short rod 344, one end of the second carrying long rod 341 is movably arranged on the second movable slot 325, and one end of the second carrying short rod 344 is movably arranged on the first movable slot 324; the second carrying long rod 341 is controlled to swing through the long rod driving part 342 arranged at the bottom of the support plate 321; the other end of the second carrying long rod 341 is provided with a second long rod abutting ring 343; the second carrying short rod 344 is controlled to swing through the short rod driving part 345 arranged at the bottom of the support plate 321; and the other end of the second carrying short rod 344 is provided with a second short rod abutting ring 346. The second carrying long rod 341 and the second carrying short rod 344 can swing from the outer periphery of the sealing assembly 40 to approach the outer periphery of the sealing assembly 40 through cooperation with the first movable slot 324 and the second movable slot 325 on the support plate 321, and finally stably clamp the outer periphery wall of the sealing assembly 40 through the respective abutting rings.

[0052] In order to prevent the sealing assembly 40 from falling during the process of entering the waiting area, the length of the second carrying long rod 341 needs to be greater than the length of the second carrying short rod 344, so as to timely intercept the falling sealing assembly 40; in order to prevent the sealing assembly 40 entering the waiting area from sliding out of the waiting area under the action of inertia, the length of the second carrying short rod 344 needs to be greater than the length of the first carrying rod 331, so as to block the sealing assembly 40.

[0053] The assembly assembly 20 comprises an assembly support 21, an assembly unit 22 and a detection unit 23; the assembly support 21 is installed on the top of the mounting rack 50 through the assembly support 21, the assembly unit 22 is driven by the assembly driving part 221 to press the pressing head 222, performs pressing operation on the sealing assembly 40 located on the workbench 24, the sealing assembly 40 after pressing is completed is moved from the first machining area to the second machining area by the first carrying unit 33, and the sealing assembly 40 after pressing is detected by the detection unit 23.

[0054] As shown in Figure 1 A sealing assembly 40 assembly method comprises steps S10-S40.

[0055] Step S10: based on the conveying unit 11, the sealing assembly 40 is conveyed to the pushing position, and the pushing unit 12 pushes the sealing assembly 40 to the waiting area; the sealing assembly 40 is conveyed to the pushing position by the conveying unit 11, and then the sealing assembly 40 is pushed to the waiting area by the pushing unit 12, realizing the automatic connection of continuous conveying of the sealing assembly 40 to accurate positioning. This not only lays the foundation for subsequent carrying and processing, but more importantly, this step prepositions the sealing assembly 40 in a certain waiting area, creates a prerequisite for the subsequent specific and targeted clamping action of the second carrying unit 34, and thus provides an initial guarantee for the accuracy and reliability of the whole process.

[0056] Step S20, drive the second carrying unit 34 to swing from the outer peripheral side of the waiting area to approach and clamp the outer peripheral wall of the sealing assembly 40 in the waiting area; by driving the second carrying 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, the key to solving the core problem of the present scheme is constituted. By means of swinging approach, the second carrying unit 34 (especially the second carrying long rod 341 thereof) can quickly form an effective barrier at the moment when the sealing assembly 40 is pushed to the waiting area, so as to realize timely interception and circumferential clamping of the edge of the sealing assembly 40. This directly solves the risk of sliding of the assembly in the waiting area due to inertia or unstable position, and ensures the stable and safe posture of the assembly before transfer.

[0057] Step S30, drive the second carrying unit 34 to translate the sealing assembly 40 in the waiting area to the first processing area; by driving the second carrying unit 34 to translate the sealing assembly 40 in the waiting area to the first processing area, the sealing assembly 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, the translation process effectively avoids shaking, deviation or falling of the assembly during movement, ensuring that the assembly can arrive at the first processing area with accurate pose, providing a solid foundation for subsequent high-quality compression assembly.

[0058] Step S40, the second carrying unit 34 leaves the first processing area and the first processing of the sealing assembly 40 in the first processing area is completed, and the first carrying unit 33 is driven to translate the sealing assembly 40 in the first processing area to the second processing area; wherein the translation of the second carrying unit 34 is synchronized with the translation of the first carrying unit 33; by setting the "second carrying unit 34 leaving" and "driving the first carrying unit 33 to translate the sealing assembly 40 to the second processing area" and synchronizing them, the seamless connection and efficient circulation of carrying tasks between different stations are realized. This synchronous operation strategy enables the second carrying unit 34 to return immediately after unloading to perform the next clamping task, while the first carrying unit 33 simultaneously takes over the conveying task of the next station. This greatly shortens the waiting time between processes and eliminates the idle gap in the carrying process, thereby significantly improving the production rhythm and overall efficiency of the entire assembly system.

[0059] Specifically, as shown in Figure 2 Step S20 includes steps S21-S23.

[0060] Step S20, the driving of the second carrying 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] Step S21, based on part of the second carrying unit 34 aligning with the waiting area, driving the second carrying long rod 341 to swing in the direction of the sealed assembly 40 to be clamped, and driving the second carrying short rod 344 to swing in the direction perpendicular to the pushing direction of the pushing unit 12; part of the second carrying unit 34 aligning with the waiting area needs to make the second carrying long rod 341 swing in advance so that it can enter the possible moving path of the sealed assembly 40 as early as possible, forming a front barrier, which greatly enhances the interception ability to prevent the sealed assembly 40 from accidentally falling off; the second carrying short rod 344 swings to the vertical state, which is equivalent to pre-blocking the sealed assembly 40 to prevent it from sliding out of the waiting area by inertia; the second carrying long rod 341 and the second carrying short rod 344 cooperatively constitute a preliminary and open surrounding area, which is equivalent to pre-arranging clamping jaws on both sides of the sealed assembly 40, laying the optimal spatial posture foundation for the next step of accurate and efficient collection and clamping.

[0062] Step S22, the sealed assembly 40 enters the range of the second carrying long rod 341 and the second carrying short rod 344, and reaches the state to be clamped; wherein the state to be clamped includes that more than half of the projection area of the sealed assembly 40 is located on one side of the end of the second carrying long rod 341 located on the assembly assembly 20; the quantitative requirement of the projection area of the sealed assembly 40 ensures that the center of gravity has stabilized across the protective boundary of the second carrying long rod 341, creating optimal mechanical conditions for subsequent collection and clamping of the second carrying long rod 341, so that the sealed assembly 40 will not be out of the range during clamping, greatly improving the stability and reliability of the carrying process.

[0063] Step S23, the second carrying long rod 341 swings towards the direction close to the outer peripheral wall of the sealed assembly 40, and the second carrying short rod 344 swings towards the direction close to the outer peripheral wall of the sealed assembly 40, until the second carrying long rod 341 and the second carrying short rod 344 swing to abut against the outer peripheral wall of the sealed assembly 40; the combined motion of the active swing of the second carrying long rod 341 and the second carrying short rod 344 enables the second carrying unit 34 to approach and envelope the sealed assembly 40 from multiple directions in a soft and precise manner. It avoids the possible overturning of the sealed assembly 40 caused by single rigid impact, ensures the stability and controllability of the clamping process, and provides dynamic protection for forming a stable and reliable clamping state. This multi-point circumferential contact abutting mode can uniformly apply clamping force to the outer peripheral wall of the sealed assembly 40, forming stable multi-point positioning. Not only can it effectively prevent the assembly from slipping off during subsequent carrying, but also can avoid the deformation or damage of the sealing ring 41 caused by single-point stress concentration, finally realizing safe, damage-free and firm clamping of the sealed assembly 40.

[0064] Further, based on the alignment of the second carrying unit 34 and the waiting area, the second carrying long rod 341 is driven to swing in the direction of the sealed assembly 40 to be clamped, and the second carrying short rod 344 is driven to swing in the direction perpendicular to the pushing direction of the pushing unit 12. The driving of the second carrying short rod 344 to swing in the direction perpendicular to the pushing direction of the pushing unit 12 includes that the second carrying short rod 344 is first swung away from the sealed assembly 40 to be clamped, and then the second carrying short rod 344 is swung to the direction perpendicular to the pushing direction of the pushing unit 12 after reaching the waiting area.

[0065] The second carrying short rod 344 swings outward to avoid collision with the outer circumferential wall of the sealed assembly 40 after the first machining in the subsequent repeated movement process, and clears a safe path for the subsequent action, thereby ensuring the reliability of the equipment operation. The second carrying short rod 344 is swung to the perpendicular state to effectively block the sealed assembly 40 in advance, prevent the sealed assembly 40 from sliding out of the waiting area by inertia, thereby eliminating the interference risk and providing a guarantee for the subsequent accurate and stable clamping of the assembly, and improving the smoothness and success rate of the entire carrying process.

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

[0067] The end of the second carrying long rod 341 can be pre-stretched into the front of the path where the sealed assembly 40 may fall after the second carrying long rod 341 moves to the sealed assembly 40, thereby forming an effective interception in the physical space. When the sealed assembly 40 is pushed to the waiting area, even if it slides due to inertia and other factors, it will be blocked by the end of the second carrying long rod 341 in time. This design upgrades the second carrying long rod 341 from a simple clamping component to a mechanism with a pre-protection function, which prevents the assembly from falling in the waiting station from the source by precise spatial layout, greatly improving the reliability and success rate of the feeding process.

[0068] Further, D2 < D; wherein D is the outer circumferential diameter of the sealed assembly 40; and in the step of driving the second carrying short rod 344 to swing in the direction perpendicular to the pushing direction of the pushing unit 12, D2 is the distance between the two second carrying short rods 344 on both sides of the sealed assembly 40.

[0069] When the second carrying short rod 344 swings to the vertical state, the channel formed between the two oppositely arranged second carrying short rods 344 is naturally smaller than the diameter of the sealing assembly 40. This design allows the two second carrying short 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 carrying long rod 341, forms a three-dimensional protection mechanism that simultaneously restricts 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 escaping from the waiting area.

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

[0071] The second carrying short rod 344 ensures that it converges to abut against the sealing assembly 40 with exactly the same trajectory and path each time, thereby accurately pushing and positioning the sealing assembly 40 at the preset center of the first processing area. This highly repetitive positioning action effectively eliminates the deviation of the final position of the assembly caused by the randomness of the clamping posture, solves the centering 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 guarantees the uniformity of the processing quality such as pressing and the product yield.

[0072] Specifically, as shown in FIG. 8, step S40 includes steps S41-S45. Figure 3

[0073] Step S40, the second carrying unit 34 is away from the first processing area and the first processing of the sealing assembly 40 in the first processing area is completed, and the first carrying unit 33 is driven to translate the sealing assembly 40 in the first processing area to the second processing area, including:

[0074] ​Step S41, after the sealing assembly 40 reaches the first processing area, the assembly assembly 20 performs first processing on the sealing assembly 40; establish the logical premise between the two core processes of conveying and processing. Ensure the accuracy and timeliness of the processing action. Only after the previous process (conveying) is confirmed to be completed, the next process (assembly) will start, which avoids the risk of misprocessing when the sealing assembly 40 is not in place or interfering with processing during the conveying process, and ensures the independence of each station operation and the rigor of the process.

[0075] Step S42, after the sealing assembly 40 completes the first processing in the first processing area, the driving unit 31 drives the second conveying unit 34 to separate from the outer peripheral wall of the sealing assembly 40 and moves away from the first processing area to the direction of the next sealing assembly 40 to be clamped; realize the rapid conversion of the function of the second conveying unit 34. Its beneficial effects are: on the one hand, the "separation" action ensures that the second conveying unit 34 can safely and without interference from the processed assembly; on the other hand, it immediately moves to the next sealing assembly 40 to be clamped, aiming to make full use of the spare time in the production cycle to pre-position for starting the next working cycle, which is a key step to improve the overall efficiency of the system.

[0076] Step S43, the first conveying unit 33 moves to the sealing assembly 40 in the first processing area at the same time; "at the same time" is the core of this step, which realizes the parallel operation of the two actions of "second conveying unit 34 leaving" and "first conveying unit 33 replacing" in time. This design eliminates the waiting interval in traditional sequential operation, greatly compresses the transfer time between processes, and provides a core guarantee for realizing continuous and efficient assembly line operation.

[0077] Step S44, when the first conveying unit 33 reaches the first processing area, the driving unit 31 drives the first conveying unit 33 to approach the sealing assembly 40 until the first conveying rod 331 abuts against the outer peripheral wall of the sealing assembly 40; make the first conveying unit 33 establish connection with the sealing assembly 40 that has completed processing in an active approach, and form stable clamping through "abutment". This flexible and targeted contact method can effectively avoid impacting or damaging the processed assembly, ensuring that the assembly is smoothly and safely taken over from a stationary state, and preparing for subsequent transfer.

[0078] Step S45, drive the first carrying unit 33 to drive the sealing assembly 40 of the first processing area to the second processing area; the semi-finished product passing through the first processing area can be timely and accurately transported away from the current station and transported to the second processing area for detection by the detection unit 23, which also creates conditions for discharging, thereby ensuring the continuity and integrity of the entire assembly process, which is the core link of realizing multi-station and multi-process automatic assembly.

[0079] Further, after the sealing assembly 40 completes the first processing in the first processing area, the second carrying unit 34 is driven to separate from the outer peripheral wall of the sealing assembly 40 and move away from the first processing area to the direction of the next station to be clamped to the sealing assembly 40. In the step of moving the second carrying unit 34 away from the first processing area to the direction of the next station to be clamped to the sealing assembly 40, the support plate 321 is close to the end of the one end of the conveying unit 11, and the distance between the support plate 321 and the conveying unit 11 is reduced and greater than zero.

[0080] The support plate 321 does not need to be in contact with the conveying unit 11 under the drive of the driving unit 31, because the swing of the second carrying long rod 341 prevents the sealing assembly 40 from falling. The present scheme not only saves kinetic energy, but also effectively prevents mechanical interference or collision between the carrying assembly 30 and the conveying unit 11, which guarantees the safety and reliability of the equipment operation and avoids downtime or component damage caused by collision.
