Description

Technical Field

[0001] This invention relates to the field of sealing ring production technology, specifically to a cleaning device and method for cleaning sealing rings after trimming. Background Technology

[0002] In the production of precision sealing rings, the trimming process is an indispensable and crucial step. Its purpose is to remove burrs and flash generated after molding or injection molding, in order to obtain a finished product with precise dimensions and a smooth contour. However, during the trimming and cutting process, the sharp blade inevitably shreds some of the rubber material when cutting off excess rubber trim, forming particles of varying sizes. Due to the viscoelasticity of the rubber material itself and the instantaneous high temperature and pressure generated during cutting, these micron-sized rubber fragments easily adhere to and accumulate near the cutting edge of the trimming tool.

[0003] As the cutting tool continues its subsequent trimming operations, the rubber particles already attached to the cutting edge come into contact with the surface of the new sealing ring as the tool moves. Under the mechanical pressure applied during trimming, they are forcefully pressed onto the surface of the sealing ring, creating a strong adhesion between the rubber particles and the ring. Traditional cleaning techniques, such as water rinsing, ultrasonic vibration, or high-pressure airflow purging, often fail to achieve satisfactory cleaning results. This leads to interference signals in subsequent high-precision optical dimension and appearance inspections, causing misjudgments or measurement errors and affecting the reliability and efficiency of the inspection. More seriously, if sealing rings with such embedded particles are used in hydraulic, pneumatic, or other sealing systems, their surface smoothness and material uniformity are compromised. Under long-term dynamic pressure and friction conditions, this can become a potential source of early failure, thus affecting the sealing safety and long-term operational stability of the entire equipment system. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning device and method for cleaning sealing rings after trimming, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A cleaning device for cleaning sealing rings after trimming, comprising:

[0007] The cleaning tank body has an inner cylinder installed inside. The inner cylinder is equipped with a composite rotating component and multiple sets of follower disks. When the composite rotating component is activated, it can drive the multiple sets of follower disks to perform circular motion and rotate on their own axis.

[0008] It also includes: multiple sets of tensioning mechanisms disposed on the follower disk, the tensioning mechanism comprising:

[0009] Two sets of support arms are slidably mounted on the follower disk. The two sets of support arms can move relative to each other to support the sealing ring, and multiple sets of inclined surfaces are equidistantly arranged on the support arms.

[0010] Multiple sets of pushers are slidably mounted on the support arm. A support structure for supporting the sealing ring is slidably mounted inside the pusher. The support structure can move along the length direction of the inclined surface when the pusher moves along the length direction of the support arm.

[0011] When one of the pushers moves along the corresponding support arm, it can cause one end of the sealing ring to twist.

[0012] The cleaning equipment for the sealing ring after trimming, as described above, has a connecting rod fixedly installed on the follower plate, and a set of sliding parts are slidably installed at each end of the connecting rod, and the sliding parts are fixedly connected to the support arm.

[0013] A double-headed cylinder is fixedly installed on the connecting rod, and the actuating end of the double-headed cylinder is connected to the sliding member;

[0014] Each of the two sets of sliding members is fixedly equipped with a set of electric telescopic rods. The actuating end of the electric telescopic rods is fixedly connected to the jacking member, and the actuating end of one set of electric telescopic rods is connected to the connecting rod through a reverse traction structure.

[0015] The cleaning equipment for the sealing ring after trimming, as described above, includes a reverse pulling structure comprising a drive shaft fixedly connected to the moving end of the electric telescopic rod and a guide plate passing through the sliding member and detachably connected to the connecting rod. The guide plate is provided with a guide groove, and the drive shaft is capable of rolling within the guide groove.

[0016] When the electric telescopic rod drives the jacking member to move along the length of the support arm, the two sets of support arms can move closer to or further away from each other.

[0017] The cleaning device for the sealing ring after trimming, as described above, includes a horizontal groove and an inclined groove disposed on the guide plate. The horizontal groove and the inclined groove are symmetrical, and the angle between the inclined groove and the vertical plane is equal to the angle between the corresponding inclined plane and the vertical plane.

[0018] As described above, the cleaning device for the sealing ring after trimming: the support arm is provided with multiple sets of first guide grooves at equal intervals along its length direction, and the convex shaft provided on the side of the pusher can roll in the first guide groove;

[0019] The multiple sets of pushing members are fixedly connected to each other, and the pushing member located at the end is connected to the electric telescopic rod.

[0020] As described above, the cleaning equipment for the sealing ring after trimming: the supporting structure includes a sliding connector slidably installed in the push member, two sets of support rollers are rotatably installed on the sliding connector, and a fitting shaft and a follower shaft are provided on the sliding connector. The fitting shaft is in rolling engagement with the guide groove provided on the push member, and the follower shaft can pass through the through groove provided on the push member and be in rolling engagement with the second guide groove provided on the support arm.

[0021] The cleaning device for sealing ring trimming as described above: the composite rotating assembly includes:

[0022] Two sets of linear drive modules are installed at the rear of the cleaning tank body, and a bearing plate is rotatably mounted on the linear drive module;

[0023] A rotating disk is rotatably connected to the carrier disk. A drive motor mounted on the carrier disk can drive the rotating disk to rotate. A rotating sealing ring is provided on the side of the rotating disk, and the rotating sealing ring is adapted to the inner cylinder.

[0024] The meshing structure provided on the follower disk and the carrier disk can drive the follower disk to rotate when the carrier disk rotates.

[0025] The cleaning device for the sealing ring after trimming, as described above, includes a second toothed ring fixedly connected to the bearing plate and a first toothed ring fixedly connected to the follower plate on the same axis, wherein the first toothed ring meshes with the second toothed ring.

[0026] The cleaning device for the sealing ring after trimming, as described above, has multiple sets of spray nozzles distributed in an arc shape at the top of the inner cylinder, and a return port is provided at the bottom of the inner cylinder.

[0027] A method for cleaning a sealing ring using the aforementioned cleaning equipment for trimming sealing rings includes the following steps:

[0028] Step 1: Control the linear drive module to pull the composite rotating component out of the inner cylinder. When the composite rotating component moves to the predetermined position, rotate the composite rotating component. At this time, the two sets of support arms are in a close-to-each-other state. Then place the sealing ring to be cleaned on the inclined surface corresponding to the support arm.

[0029] Step 2: The two sets of support arms move away from each other, supporting the sealing ring. At this time, the sealing ring moves along the inclined surface and comes into contact with the supporting structure.

[0030] Step 3: Reverse the rotation of the composite rotating component and reverse the movement of the linear drive module to make the composite rotating component enter the inner cylinder;

[0031] Step 4: The composite rotating component moves, causing the support arm to drive the sealing ring to make a circular motion and rotate on its own axis. At the same time, the external cleaning fluid pumping device pumps cleaning fluid toward the spray nozzle.

[0032] Step 5: One set of electric telescopic rods drives the jacking component to move, so that one end of the sealing ring can move and twist along the inclined surface;

[0033] Step Six: Another set of electric telescopic rods moves and drives the jacking component to move, causing the other end of the sealing ring to twist. At this time, the sealing ring rolls as a whole at a predetermined angle, and the two sets of support arms move closer to each other.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] By using the designed support arm, pusher, and support structure, when one set of pushers moves and drives one end of the sealing ring to move along the inclined surface, the sealing ring can be stretched and twisted, causing the surface of the sealing ring to deform. This allows impurities with strong adhesion on the surface of the sealing ring to create gaps or even peel off from the sealing ring. At this time, combined with the flushing of the cleaning fluid, the cleaning effect of the sealing ring can be greatly improved. When another set of pushers acts on the other end of the sealing ring, the sealing ring can be rolled as a whole. In this way, the side of the sealing ring that was originally in contact with the support arm will be transferred and exposed to the side away from the support arm, so that this part of the area can be thoroughly cleaned, ensuring the comprehensiveness of the cleaning.

[0036] By using a drive shaft and guide plate, the amount of further stretching of the sealing ring when the next set of pushers moves can be offset by the reverse movement of the support arm, ensuring that the sealing ring can be twisted normally and will not undergo irreversible deformation due to excessive stretching.

Detailed Implementation

[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0051] Please see Figures 1-12 As one embodiment of the present invention, the cleaning device for the sealing ring after trimming includes:

[0052] The cleaning tank body 1 is equipped with an observation window 101 and an inner cylinder 2. The inner cylinder 2 is equipped with a composite rotating component and multiple sets of follower disks 7. When the composite rotating component is activated, it can drive the multiple sets of follower disks 7 to perform circular motion and rotate. The top of the inner cylinder 2 is distributed with multiple sets of spray nozzles 3 in an arc shape, and the bottom of the inner cylinder 2 is equipped with a return port 4. By placing the spray nozzles 3 at the top of the inner cylinder 2, the cleaning fluid can flush the sealing ring under the action of the initial spray force and gravity during the spraying process, thereby producing a better flushing effect to ensure that the impurities on the sealing ring are flushed as cleanly as possible. Furthermore, the cleaning tank body 1 is equipped with a water pump device (not shown in the figure), which can pump the cleaning fluid into the spray nozzles 3, and the cleaning fluid can flow out from the return port 4 after acting on the sealing ring.

[0053] The composite rotating component includes:

[0054] Two sets of linear drive modules 10 are installed at the rear of the cleaning tank body 1, and a bearing plate 9 is rotatably mounted on the linear drive module 10;

[0055] A rotating disk 5 is rotatably connected to the support disk 9. A drive motor 11 mounted on the support disk 9 can drive the rotating disk 5 to rotate. A rotating sealing ring 6 is provided on the side of the rotating disk 5. The rotating sealing ring 6 is adapted to the inner cylinder 2 to ensure sealing.

[0056] The meshing structure provided on the follower disk 7 and the carrier disk 9 can drive the follower disk 7 to rotate when the carrier disk 9 rotates. The meshing structure includes a second toothed ring 12 fixedly connected to the carrier disk 9 and a first toothed ring 8 fixedly connected to the follower disk 7 on the same axis. The first toothed ring 8 meshes with the second toothed ring 12.

[0057] In this embodiment, the linear drive module 10 can drive the carrier plate 9 to move along the central axis of the inner cylinder 2, thereby pulling the carrier plate 9 out of the inner cylinder 2. After the carrier plate 9 moves to a predetermined position, its axial direction can be changed by rotating the carrier plate 9. At this time, the sealing ring to be cleaned can be put on the support arm 18 by the corresponding robotic arm or manual labor.

[0058] During the cleaning process, the drive motor 11 drives the rotating disk 5 to rotate. At this time, multiple sets of support arms 18 drive the sealing ring to make a circular motion, so that the sealing ring can make uniform contact with the sprayed cleaning liquid, thereby improving the cleaning effect. When the rotating disk 5 rotates, the first toothed ring 8 and the second toothed ring 12 on the follower disk 7 mesh, so that the follower disk 7 will also rotate along its own central axis. At this time, the sealing ring not only makes a circular motion but also rotates, which further improves the contact effect between the sealing ring and the cleaning liquid, and to a certain extent further improves the cleaning effect.

[0059] Please see Figures 6-12 The follower plate 7 is provided with multiple tensioning mechanisms, which include two sets of support arms 18 and multiple sets of pushers 19.

[0060] The two sets of support arms 18 are slidably mounted on the follower disk 7. Specifically, the follower disk 7 is provided with a sliding groove 701, and a sliding baffle 13 fixedly connected to the support arm 18 is slidably mounted in the sliding groove 701. An extension plate is provided on the rear side of the sliding baffle 13. The length of the extension plate is greater than the length of the sliding groove 701. This ensures that the extension plate can always block the sliding groove 701 as the two sets of support arms 18 move closer or further apart, thereby preventing the cleaning fluid from flowing into the side of the follower disk 7 away from the support arm 18. This improves the sealing effect of the device and ensures that the electrical drive components installed on the side of the follower disk 7 away from the support arm 18 have a good working environment.

[0061] The two sets of support arms 18 can move relative to each other to support the sealing ring, and multiple sets of inclined surfaces 1801 are equidistantly arranged on the support arms 18. Small protrusions are provided on the surface of the inclined surfaces 1801. These protrusions can increase the friction when the sealing ring moves, so as to ensure that the sealing ring can be twisted when it is pushed to move along the inclined surfaces 1801.

[0062] A connecting rod 15 is fixedly installed on the follower disk 7. A set of sliding parts 14 are slidably installed at each end of the connecting rod 15. The sliding parts 14 are fixedly connected to the support arm 18.

[0063] A double-headed cylinder 16 is fixedly installed on the connecting rod 15, and the actuating end of the double-headed cylinder 16 is connected to the sliding member 14.

[0064] Each of the two sets of sliding members 14 is fixedly installed with a set of electric telescopic rods 17. The actuating end of the electric telescopic rod 17 is fixedly connected to the pushing member 19, and the actuating end of one set of electric telescopic rods 17 is connected to the connecting rod 15 through a reverse traction structure.

[0065] In the initial state, the dual-head cylinder 16 controls the two sets of support arms 18 to be close to each other. At this time, it is easier to put the sealing ring to be cleaned onto the two sets of support arms 18. In order to further improve the stability of the sealing ring after placement, the support arms 18 can be adjusted to the upward state before placing the sealing ring, that is, the inclined surface 1801 is in the upward state. At this time, the sealing ring can be at the end of the inclined surface 1801 under its own weight, so that the sealing ring has sufficient stability when the two sets of support arms 18 move away from each other and tighten the sealing ring.

[0066] Please see Figures 11-12 The reverse traction structure includes a drive shaft 1701 fixedly connected to the moving end of the electric telescopic rod 17 and a guide plate 22 passing through the sliding member 14 and detachably connected to the connecting rod 15. The guide plate 22 is provided with a guide groove, and the drive shaft 1701 can roll in the guide groove.

[0067] When the electric telescopic rod 17 drives the jacking member 19 to move along the length of the support arm 18, the two sets of support arms 18 can move closer to or further away from each other.

[0068] The guide groove includes a horizontal groove 2201 and an inclined groove 2202 disposed on the guide plate 22. The horizontal groove 2201 and the inclined groove 2202 are symmetrical, and the angle between the inclined groove 2202 and the vertical plane is equal to the angle between the corresponding inclined plane 1801 and the vertical plane.

[0069] In this embodiment, in the initial state, the drive shaft 1701 is at the end of the horizontal groove 2201 away from the inclined groove 2202. At this time, the distance between the two sets of support arms 18 is the smallest. When the double-headed cylinder 16 is activated, the two sets of sliding parts 14 will move away from each other. At this time, the drive shaft 1701 will move along the length direction of the horizontal groove 2201. When the drive shaft 1701 moves to the end of the horizontal groove 2201, the two sets of support arms 18 complete a certain degree of tension on the sealing ring, so that the surface of the sealing ring reaches a certain degree of elastic deformation. At this time, the surface of the sealing ring has a stretched effect, which reduces the contact area between the impurities with strong adhesion to the sealing ring and the sealing ring, thus reducing the adhesion between these impurities and the sealing ring. At this time, combined with the impact of the cleaning fluid, the cleaning effect on these impurities can be improved.

[0070] Furthermore, in this application, when the sealing ring is fitted onto the two sets of support arms 18, the electric telescopic rod 17 without a drive shaft 1701 will act first to push one end of the sealing ring along the length direction of the inclined surface 1801. At this time, one end of the sealing ring can be further stretched and twisted. Subsequently, the other set of electric telescopic rods 17 will act, pushing the other end of the sealing ring to move along the inclined surface 1801. In this process, theoretically, the sealing ring will be further stretched, and as the degree of stretching of the sealing ring increases, the difficulty of twisting the sealing ring increases, and the... This can easily lead to irreversible deformation of the sealing ring due to excessive stretching. However, when the set of electric telescopic rods 17 is activated, the drive shaft 1701 will move along the inclined groove 2202, causing the support arm 18 corresponding to the set of electric telescopic rods 17 to move towards another set of support arms 18. Since the angle between the inclined groove 2202 and the vertical plane is equal to the angle between the corresponding inclined plane 1801 and the vertical plane, the amount of further stretching of the sealing ring is offset by the reverse movement of the support arm 18, ensuring that the sealing ring can be twisted normally and will not undergo irreversible deformation due to excessive stretching.

[0071] It should be noted that the above-mentioned increase in the difficulty of twisting the sealing ring as the degree of stretching of the sealing ring increases specifically means that, taking the sealing ring with a circular cross-section as an example, when the sealing ring is stretched to a great extent, the position where it is connected to the support arm 18 will be deformed due to the tension, that is, it will change from the original circle to a flat circle or even a strip shape. At this time, when pushing the sealing ring to move, it will be very difficult to twist the sealing ring, and frictional breakage may occur during friction.

[0072] Please see Figures 6-10 Multiple sets of pushers 19 are slidably mounted on the support arm 18. A support structure for supporting the sealing ring is slidably mounted inside the pusher 19. The support structure can move along the length direction of the inclined surface 1801 when the pusher 19 moves along the length direction of the support arm 18.

[0073] The support arm 18 is provided with multiple sets of first guide grooves 1802 at equal intervals along its length direction, and the convex shaft 1903 provided on the side of the pusher 19 can roll in the first guide grooves 1802.

[0074] Multiple sets of the pushing members 19 are fixedly connected to each other, and the pushing member 19 located at the end is connected to the electric telescopic rod 17;

[0075] The supporting structure includes a sliding connector 20 slidably installed in the pusher 19. Two sets of support rollers 21 are rotatably mounted on the sliding connector 20. The sliding connector 20 is provided with a fitting shaft 2001 and a follower shaft 2002. The fitting shaft 2001 is in rolling engagement with a guide groove 1901 provided on the pusher 19. The follower shaft 2002 can pass through the through groove 1902 provided on the pusher 19 and be in rolling engagement with the second guide groove 1803.

[0076] When one of the pushers 19 moves along the corresponding support arm 18, it can drive one end of the sealing ring to twist.

[0077] In this embodiment, in the initial state, the convex shaft 1903 is at the top of the first guide groove 1802. At this time, when the two sets of support arms 18 move away from each other, the sealing ring will be subjected to a pulling force. Under the action of the pulling force, when the sealing ring abuts against the inclined surface 1801, the sealing ring will move along the inclined surface 1801 toward the sliding member 14 until it abuts against the two sets of support rollers 21 on the push member 19. At this time, the sealing ring can be in a stable state between the two sets of support arms 18, where the two sets of support rollers 21 can rotate freely. This makes it so that when the push member 19 pushes the sealing ring to move along the inclined surface 1801, the sealing ring will only have friction with the inclined surface 1801, and only rolling friction with the push member 19. This ensures that when the sealing ring is pushed to move, it can be twisted, avoiding the friction between the sealing ring and the push member 19, which would inhibit the twisting of the sealing ring.

[0078] After cleaning for a certain period of time under the above conditions, the electric telescopic rod 17 without a drive shaft 1701 will be activated first, pushing the pusher 19 connected to it to move along the length direction of the first guide groove 1802. At this time, the sealing ring will move along the inclined surface 1801, and the follower shaft 2002 will move along the second guide groove 1803, so that the pusher 19 can move along the second guide groove 1803 and the guide groove 1901 respectively. This ensures that even during the movement process, the two sets of support rollers 21 can still support the sealing ring and ensure the torsion of the sealing ring.

[0079] Furthermore, when the pusher 19 within one set of support arms 18 moves, it can cause one end of the sealing ring that rests on the support arm 18 to twist. During this process, the other end of the sealing ring is stationary, causing the sealing ring to twist and be further stretched. At this time, the sealing ring can deform along its length and along its axial direction, thereby allowing impurities with strong adhesion to the sealing ring to peel off from the sealing ring and create gaps. Simultaneously, with the flushing of the cleaning fluid, the cleaning degree of the sealing ring is ensured to the greatest extent.

[0080] Furthermore, when the pusher 19 on one side of the support arm 18 moves, the pusher 19 on the other side of the support arm 18 will also move, causing the other side of the sealing ring to twist. After this side twists, the sealing ring can roll on the inclined surface 1801. During this process, the side of the sealing ring that was originally in contact with the support arm 18 will be transferred and exposed to the side away from the support arm 18, so that this part of the area can be thoroughly cleaned, ensuring the comprehensiveness of the cleaning.

[0081] As an embodiment of the present invention, a method for cleaning a sealing ring using the aforementioned cleaning equipment for trimming sealing rings is also provided, comprising the following steps:

[0082] Step 1: Control the linear drive module 10 to pull the composite rotating component out of the inner cylinder 2. When the composite rotating component moves to the predetermined position, rotate the composite rotating component. At this time, the two sets of support arms 18 are in a close-to-each-other state. At this time, place the sealing ring to be cleaned on the inclined surface 1801 corresponding to the support arm 18.

[0083] Step 2: The two sets of support arms 18 move away from each other, supporting the sealing ring. At this time, the sealing ring moves along the inclined surface 1801 and comes into contact with the supporting structure.

[0084] Step 3: Reverse the rotation of the composite rotating component and reverse the linear drive module 10 to make the composite rotating component enter the inner cylinder 2;

[0085] Step 4: The composite rotating component moves, causing the support arm 18 to drive the sealing ring to make a circular motion and rotate on its own axis. At the same time, the external cleaning fluid pumping device pumps cleaning fluid toward the spray port 3.

[0086] Step 5: One set of electric telescopic rods 17 drives the pusher 19 to move, so that one end of the sealing ring can move and twist along the inclined surface 1801;

[0087] Step 6: Another set of electric telescopic rods 17 is activated and drives the pusher 19 to move, causing the other end of the sealing ring to twist. At this time, the sealing ring rolls as a whole at a predetermined angle, and the two sets of support arms 18 move closer to each other.

[0088] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.

When the sealing ring is fitted onto the two sets of support arms, the electric telescopic rod without a drive shaft will move first to push one end of the sealing ring along the length of the inclined surface. At this time, one end of the sealing ring can be further stretched and twisted. Then, the other set of electric telescopic rods will move, causing the support arm corresponding to the set of electric telescopic rods to move toward the other set of support arms. This makes the amount of further stretching of the sealing ring canceled out by the reverse movement of the support arm, ensuring that the sealing ring can be twisted normally. The composite rotating component includes: Two sets of linear drive modules are installed at the rear of the cleaning tank body, and a bearing plate is rotatably mounted on the linear drive module; A rotating disk is rotatably connected to the carrier disk. A drive motor mounted on the carrier disk can drive the rotating disk to rotate. A rotating sealing ring is provided on the side of the rotating disk, and the rotating sealing ring is adapted to the inner cylinder. The meshing structure provided on the follower disk and the carrier disk can drive the follower disk to rotate when the carrier disk rotates.

7. A method for cleaning a sealing ring using the cleaning equipment for cleaning sealing rings after trimming as described in any one of claims 1 to 6, characterized in that, Includes the following steps: Step 1: Control the linear drive module to pull the composite rotating component out of the inner cylinder. When the composite rotating component moves to the predetermined position, rotate the composite rotating component. At this time, the two sets of support arms are in a close-to-each-other state. Then place the sealing ring to be cleaned on the inclined surface corresponding to the support arm. Step 2: The two sets of support arms move away from each other, supporting the sealing ring. At this time, the sealing ring moves along the inclined surface and comes into contact with the supporting structure. Step 3: Reverse the rotation of the composite rotating component and reverse the movement of the linear drive module to make the composite rotating component enter the inner cylinder; Step 4: The composite rotating component moves, causing the support arm to drive the sealing ring to make a circular motion and rotate on its own axis. At the same time, the external cleaning fluid pumping device pumps cleaning fluid toward the spray nozzle. Step 5: One set of electric telescopic rods drives the jacking component to move, so that one end of the sealing ring can move and twist along the inclined surface; Step Six: Another set of electric telescopic rods moves and drives the jacking component to move, causing the other end of the sealing ring to twist. At this time, the sealing ring rolls as a whole at a predetermined angle, and the two sets of support arms move closer to each other.
