Description

Technical Field

[0001] This invention relates to the field of sealing ring testing technology, specifically an automatic feeding and testing device and method for large-size sealing rings. Background Technology

[0002] With the continuous improvement of automation in modern industry, sealing rings, as key sealing components, have been widely used in automobiles, aerospace, petrochemicals, medical equipment, and other fields. The quality of sealing rings directly affects the sealing performance and operational safety of the entire system; therefore, high-precision and high-efficiency automated testing of sealing rings is particularly important.

[0003] In existing large-size sealing ring automatic feeding technology, a pull rod is generally used to pull the sealing ring in a straight line from the initial support surface to the middle "C" shaped constraint, so that the sealing ring is flattened into a flat round shape, so that the two sets of calipers can be inserted into the ring and move away from each other to complete the tensioning and transfer.

[0004] However, since the sealing ring is always in contact with the supporting surface during the sliding process, the uneven distribution of friction can easily cause unpredictable torsion. Once this torsion enters the constraint, it is maintained. As a result, when the sealing ring is tightened by the caliper and the inspection is carried out, the local deformation and stress concentration caused by the torsion will cause the vision inspection system to have image misalignment or size calculation drift during scanning, which will ultimately directly manifest as inspection error or even misjudgment.

[0005] Meanwhile, when the sealing ring is pulled into the middle constraint, the upper surface of the middle constraint is in a state of complete contact with the sealing ring. Although the chuck can be pressed down to contact the upper surface of the constraint, during the subsequent tensioning process of "the two chucks moving away from each other", the two ends of the sealing ring cannot reliably slide into the recessed annular groove in the middle of the chuck due to the adsorption force and friction resistance generated by the contact surface, resulting in tensioning failure and causing the test to be interrupted. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic feeding and testing device and method for large-size sealing rings to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An automatic feeding and testing device for large-size sealing rings includes:

[0009] A frame, on which a loading tray and a transfer device are provided;

[0010] A sliding assembly, mounted on the frame, is capable of pulling a sealing ring placed on the loading tray to the transfer component;

[0011] A rotary tensioning assembly is mounted on the frame. The rotary tensioning assembly is equipped with two sets of rollers. The two sets of rollers work together to open and move the sealing ring that is pulled to the transfer component.

[0012] Also includes:

[0013] The elastic tension structure is provided in two sets and installed on the transfer component, and a support kit that penetrates the transfer component is slidably installed on the elastic tension structure;

[0014] Coaxial wheel sets are rotatably mounted on both sides of the support kit;

[0015] A side plate is fixedly installed on the transfer component. A drive plate is slidably installed on the side plate. A guide groove and a drive groove are respectively provided on the side plate and the drive plate. The coaxial wheel assembly can roll in the guide groove and the drive groove.

[0016] When the drive plate moves upward relative to the side plate, the support assembly can be conveyed to the middle of the chuck, and when the chuck separates from the transfer component, the chuck can push the support assembly to move in the opposite direction and cause the sealing ring to be fitted onto the chuck.

[0017] As described above, the large-size sealing ring automatic feeding and detection device has a through groove on the transfer component;

[0018] The elastic tension structure includes a sliding member slidably installed in the through groove, a columnar spring fixedly installed on the sliding member, and the end of the columnar spring away from the sliding member connected to the transfer member.

[0019] As described above, the large-size sealing ring automatic feeding and detection device includes a support kit that is perpendicular to the transfer member and slidably connected to the sliding member. The lower end of the link is rotatably connected to the coaxial wheel assembly, and the upper end is fixed with a support member parallel to the upper surface of the transfer member.

[0020] Two sets of rollers are rotatably mounted on the support member, and a tension belt is sleeved between the two sets of rollers. The upper surface of the tension belt is coplanar with the upper surface of the support member.

[0021] As described above, the large-size sealing ring automatic feeding and detection device includes a guide groove, which comprises a vertical groove and a first horizontal groove formed on the side plate. The vertical groove is connected to the first horizontal groove, and the vertical groove and the first horizontal groove are in a "T" shape.

[0022] As described above, the large-size sealing ring automatic feeding and detection device has a fourth cylinder fixedly mounted on the drive plate, and the actuating end of the fourth cylinder is connected to the transfer component.

[0023] The drive groove includes a second horizontal groove and an inclined groove disposed on the drive plate. The inclined groove is connected to one end of the second horizontal groove, and the length of the second horizontal groove is equal to the length of the first horizontal groove.

[0024] As described above, the automatic feeding and detection device for large-size sealing rings includes a linear drive module fixedly installed on the frame. A first drive motor is provided on the actuating end of the linear drive module, and a traction arm is connected to the output shaft of the first drive motor.

[0025] The gliding assembly also includes a first cylinder that connects to the linear drive module and is connected to the first drive motor.

[0026] As described above, the large-size sealing ring automatic feeding and detection device: the transfer component is connected to the second cylinder set on the frame, and the second cylinder can drive the transfer component to move up and down in the vertical direction of space.

[0027] The large-size sealing ring automatic feeding and detection device described above: the rotary tensioning assembly includes a rotary seat mounted on the frame and multiple tensioning structures mounted on the rotary seat, wherein the tensioning structures are connected to the cams;

[0028] The tensioning structure includes a guide rail fixedly installed on the rotating base, and a first arm and a second arm are provided on the guide rail. The first arm is connected to a third cylinder provided on the rotating base.

[0029] As described above, the large-size sealing ring automatic feeding and detection device has a second drive motor at the end of the first support arm away from the third cylinder, and the second drive motor is connected to the chuck wheel mounted on the first support arm via a toothed belt.

[0030] A method for inspecting large-size sealing rings using the aforementioned automatic feeding and inspection device includes the following steps:

[0031] Step 1: After the large-size sealing ring is produced, it will be placed on the carrier tray. At this time, the sliding component will move the large-size sealing ring on the carrier tray to the transfer component. The transfer component can squeeze the large-size sealing ring, so that the large-size sealing ring changes from a round shape to a flat round shape.

[0032] Step 2: The transfer component moves upward until the lower end of the chuck abuts against the upper end of the transfer component;

[0033] Step 3: The drive plate moves upward, so that the coaxial wheel assembly can drive the support kit to perform an upward movement first, and then move closer to the chuck wheel under the action of the guide groove and drive groove, so as to lift the two ends of the large-size sealing ring upward.

[0034] Step 4: Rotate the tensioning component to drive the two sets of rollers away from each other, push the support kit to move in the opposite direction, and at the same time switch the large-size sealing ring onto the rollers;

[0035] Step 5: The transfer component moves down, and at the same time the tensioning assembly rotates, causing the large-sized sealing ring tensioned between the two sets of rollers to switch to the testing station.

[0036] Compared with the prior art, the beneficial effects of the present invention are:

[0037] The lifting support assembly allows the sealing ring to be transferred to the chuck firstly by lifting both ends of the sealing ring upwards, separating the ends of the sealing ring from the upper surface of the transfer component. At this point, the friction between the ends of the sealing ring and the transfer component disappears, allowing the sealing ring to release the elastic potential energy stored in its torsion, thus weakening and eliminating its own degree of torsion. This prevents the torsion of the sealing ring from affecting the subsequent detection accuracy. Secondly, when the ends of the sealing ring are lifted, the height of the sealing ring ends increases, allowing the two sets of chucks to move away from each other and act on the support component, causing the support component to move. This allows the sealing ring to be directly switched from the support component to the recess in the chuck, achieving precise transfer of the sealing ring and preventing the chuck from failing to tension the sealing ring, which would lead to detection interruption.

[0038] By using a drive plate, side plates, and coaxial wheel assembly, the support member moves towards the chuck when the end of the sealing ring is lifted, ensuring stable support for the sealing ring and preventing separation between the sealing ring and the support member due to the movement of the sealing ring end, thus preventing it from being tensioned when the chuck moves. On the other hand, when the two sets of chucks move away from each other and separate from the transfer member, the support member can be driven by the chuck, allowing the sealing ring to be stably transferred from the support member to the recessed part in the middle of the chuck. This ensures that the chuck can effectively tension and transfer the sealing ring, improving detection efficiency. Attached Figure Description

[0053] 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.

[0054] Please see Figures 1-13As an embodiment of the present invention, the large-size sealing ring automatic feeding and detection device includes: a frame, a slitting assembly and a rotating tensioning assembly.

[0055] The frame is equipped with a carrying tray 1 and a transfer component 6. The transfer component 6 is connected to a second cylinder 7 mounted on the frame. The second cylinder 7 can drive the transfer component 6 to move up and down in the vertical direction. In this embodiment, the second cylinder 7 drives the transfer component 6 to move up and down, allowing the transfer component 6 to have two position states. The first state is that the transfer component 6 is at the lower end of its stroke. At this time, the upper surface of the transfer component 6 is coplanar with the upper surface of the carrying tray 1. In this state, when the sliding assembly drives the sealing ring to move, the sealing ring... The transfer device 6 can be directly pulled from the carrier plate 1 onto the transfer device 6. The transfer device 6 is a "C" shape with the opening facing upwards. This allows the transfer device 6 to constrain the sealing ring into a flat oval shape during the process of switching the sealing ring to the transfer device 6. When the sealing ring is flat and oval, the orientation of the sealing ring is constant due to the constraint of the transfer device 6, and the lateral span of the sealing ring increases. This allows the two sets of rollers to enter the sealing ring more accurately with a certain distance between them, thus ensuring stable gripping of the sealing ring in the future.

[0056] In the second state, the transfer member 6 is at the upper end of the stroke. At this time, the lower surface of the chuck 12 is in contact with the upper surface of the transfer member 6, and the two sets of chucks 12 are inside the sealing ring. This allows the sealing ring placed on the transfer member 6 to be tensioned when the two sets of chucks 12 move away from each other, so that the sealing ring can be switched from the transfer member 6 to the chuck 12.

[0057] Please see Figures 1-2 The sliding assembly is mounted on the frame and can pull the sealing ring placed on the loading tray 1 to the transfer component 6. The sliding assembly includes a linear drive module 3 fixedly mounted on the frame. A first drive motor 5 is provided on the actuating end of the linear drive module 3. A traction arm 2 is connected to the output shaft of the first drive motor 5. The traction arm 2 has an "L" shaped structure.

[0058] The gliding assembly also includes a first cylinder 4 that is connected to the linear drive module 3 and connected to the first drive motor 5.

[0059] In use, the sealing ring to be tested is placed on the loading plate 1. At this time, the first cylinder 4 drives the traction arm 2 to move downward, so that the traction arm 2 can move towards the loading plate 1 until the traction arm 2 abuts against the loading plate 1 and is inside the sealing ring. At this time, the linear drive module 3 drives the traction arm 2 to move, which can produce a pulling effect on the sealing ring. Since the upper surface of the loading plate 1 and the transfer component 6 are coplanar in this state, the traction arm 2 can directly pull the sealing ring from the loading plate 1 to the transfer component 6.

[0060] When the traction arm 2 pulls the sealing ring to the predetermined position, the first cylinder 4 will drive the traction arm 2 to move in the opposite direction, so that the end of the traction arm 2 and the sealing ring can be misaligned in the vertical space. Then the first drive motor 5 drives the traction arm 2 to rotate 90°, so as to avoid the traction arm 2 interfering with the rise of the transfer piece 6.

[0061] Please see Figure 1 , Figures 3-5 The rotary tensioning assembly is mounted on the frame and has two sets of rollers 12. The two sets of rollers 12 work together to open and move the sealing ring that is pulled to the transfer member 6.

[0062] The rotary tensioning assembly includes a rotary seat 8 mounted on the frame and multiple tensioning structures mounted on the rotary seat 8, wherein the tensioning structures are connected to the jack 12;

[0063] The tensioning structure includes a guide rail 15 fixedly installed on the rotating seat 8. A first support arm 10 and a second support arm 11 are provided on the guide rail 15. The first support arm 10 is connected to a third cylinder 9 provided on the rotating seat 8.

[0064] A second drive motor 13 is provided at the end of the first support arm 10 away from the third cylinder 9. The second drive motor 13 is connected to the chuck 12 mounted on the first support arm 10 via a toothed belt 14.

[0065] In this embodiment, the second support arm 11 is fixed on the guide rail 15, while the first support arm 10 slides on the guide rail 15. The third cylinder 9 can drive the first support arm 10 away from the second support arm 11, so that the two sets of rollers 12 on the first support arm 10 and the second support arm 11 can move away from each other, thereby achieving the tensioning of the sealing ring.

[0066] It is worth noting that in this application, the first arm 10 and the second arm 11 can also be configured to slide on the guide rail 15, and the third cylinder 9 mentioned above can be replaced with a double-headed cylinder. The double-headed cylinder can be used to drive the first arm 10 and the second arm 11 to move closer or further away from each other. In actual use, the preferred option can be chosen from these two configurations.

[0067] Furthermore, after the sealing ring is tensioned on the two sets of rollers 12, the rotating seat 8 will rotate 90° to move the sealing ring to the inspection station. A vision sensor (not shown in the figure) is installed on the upper part of the inspection station. When the sealing ring is moved above the inspection station, the second drive motor 13 will work and drive one set of rollers 12 to rotate through the toothed belt 14. At this time, the sealing ring is fitted between the two sets of rollers 12, so that when one set of rollers 12 rotates, both sets of rollers 12 will rotate, causing the sealing ring to move. This allows the sealing ring to move below the vision sensor, thereby achieving comprehensive inspection of the sealing ring and preventing local areas from being undetectable due to the obstruction of the rollers 12.

[0068] Please see Figures 6-13 The large-size sealing ring automatic feeding and detection device also includes: an elastic traction structure, a coaxial wheel group 20, and a side plate 23.

[0069] The elastic tension structure is provided in two sets and installed on the transfer member 6. A support kit that passes through the transfer member 6 is slidably installed on the elastic tension structure. The support kit includes a connecting rod 19 that is perpendicular to the transfer member 6 and slidably connected to the sliding member 21. The lower end of the connecting rod 19 is rotatably connected to the coaxial wheel set 20, and the upper end is fixed with a support member 16 that is parallel to the upper surface of the transfer member 6.

[0070] Two sets of rollers 18 are rotatably mounted on the support member 16, and a tension belt 17 is sleeved between the two sets of rollers 18. The upper surface of the tension belt 17 is coplanar with the upper surface of the support member 16.

[0071] After the sealing ring is pulled to the predetermined position, both ends of the sealing ring will be placed on the two sets of tension belts 17 respectively. In this embodiment, the connecting rod 19 can perform lifting and lateral movement. Specifically, when the connecting rod 19 moves, it will perform an upward movement and then move towards the chuck 12 (detailed below). When the connecting rod 19 moves upward, it can drive the support member 16 to move upward and use the tension belt 17 to lift both ends of the sealing ring upward. As it is lifted upward, the sealing ring can gradually be suspended from the end towards the middle. At this time, the end of the sealing ring can be separated from the transfer member 6, so that the friction between the two disappears. When the sealing ring is pulled by the traction arm 2 and twists, the sealing ring will simultaneously store a certain amount of elastic potential energy. When the end of the sealing ring is lifted, the sealing ring can release the above-mentioned elastic potential energy and the twisted area will automatically recover, thereby preventing the sealing ring from affecting the subsequent detection accuracy due to its own twist when it is fitted on the chuck 12.

[0072] Furthermore, when the sealing ring releases its elastic potential energy and the torn area automatically recovers, the tensioning band 17 will move under the action of friction, thereby reducing the friction when the sealing ring eliminates torsion, and further ensuring that the above-mentioned torsion can be weakened or even eliminated.

[0073] Furthermore, when the end of the sealing ring is lifted, its height will be higher than the lower surface of the locating wheel 12. At this time, when the two sets of locating wheels 12 move away from each other, they can directly act on the support member 16 and push the support member 16 to move in the opposite direction. This allows the sealing ring to switch from the support member 16 to the recessed part in the middle of the locating wheel 12, so that the locating wheel 12 can better tension the sealing ring and avoid the sealing ring not entering the recessed part in the middle of the locating wheel 12 during the tensioning process, which would lead to tensioning failure.

[0074] Based on the above configuration, when transferring the sealing ring to the chuck 12, firstly, the support member 16 can lift both ends of the sealing ring upwards, allowing the ends of the sealing ring to separate from the upper surface of the transfer member 6. At this time, the friction between the ends of the sealing ring and the transfer member 6 disappears, allowing the sealing ring to release the elastic potential energy stored by its own torsion, thereby weakening and eliminating its own degree of torsion, so as to avoid affecting the subsequent detection accuracy due to the torsion of the sealing ring. Secondly, when the ends of the sealing ring are lifted, the height of the ends of the sealing ring will increase, so that when the two sets of chucks 12 move away from each other, they can act on the support member 16 and cause the support member 16 to move, allowing the sealing ring to be directly switched from the support member 16 to the recess in the chuck 12, realizing the accurate transfer of the sealing ring and preventing the chuck 12 from failing to tension the sealing ring, which would lead to the interruption of the detection.

[0075] Please see Figure 7 , Figure 8 , Figures 10-13 The transfer component 6 has through slots. It should be noted that two sets of through slots are symmetrically arranged on the transfer component 6, and a groove is also provided on the transfer component 6. The groove and the through slot have the same length and orientation, and they overlap in the length direction. The support component 16 can be completely embedded in the groove. In the embedded state, the upper surface of the support component 16 and the upper surface of the tension band 17 are coplanar with the upper surface of the transfer component 6. This prevents interference or separation of the sealing ring from the end of the traction arm 2 when the traction arm 2 pulls the sealing ring due to the height difference between the transfer component 6, the support component 16, and the tension band 17. This ensures that the sealing ring can be smoothly pulled into place.

[0076] The elastic tension structure includes a sliding member 21 slidably installed in the through groove, a columnar spring 22 fixedly installed on the sliding member 21, and the end of the columnar spring 22 away from the sliding member 21 is connected to the transfer member 6;

[0077] The coaxial wheel assembly 20 is rotatably mounted on both sides of the support kit;

[0078] The side plate 23 is fixedly installed on the transfer member 6. A drive plate 24 is slidably installed on the side plate 23. A guide groove and a drive groove are respectively opened on the side plate 23 and the drive plate 24. The coaxial wheel set 20 can roll in the guide groove and the drive groove. A fourth cylinder 25 is fixedly installed on the drive plate 24. The actuating end of the fourth cylinder 25 is connected to the transfer member 6.

[0079] When the drive plate 24 moves upward relative to the side plate 23, the support assembly can be conveyed to the middle of the chuck 12, and when the chuck 12 separates from the transfer piece 6, the chuck 12 can push the support assembly to move in the opposite direction and cause the sealing ring to be fitted onto the chuck 12; wherein, the guide groove includes a vertical groove 2301 and a first horizontal groove 2302 formed on the side plate 23, the vertical groove 2301 and the first horizontal groove 2302 are connected, and the vertical groove 2301 and the first horizontal groove 2302 are in a "T" shape;

[0080] The drive groove includes a second horizontal groove 2401 and an inclined groove 2402 disposed on the drive plate 24. The inclined groove 2402 is connected to one end of the second horizontal groove 2401, and the length of the second horizontal groove 2401 is equal to the length of the first horizontal groove 2302.

[0081] In this embodiment, the aforementioned cylindrical spring 22 is in a stretched state, so that the cylindrical spring 22 provides tension and causes the sliding member 21 to tend to move toward the chuck 12. In the initial state, the coaxial wheel assembly 20 is at one end of the vertical groove 2301 away from the first horizontal groove 2302, and the coaxial wheel assembly 20 is at one end of the inclined groove 2402 away from the second horizontal groove 2401. At this time, the coaxial wheel assembly 20 is in a locked state, which locks the height of the connecting rod 19, ensuring that the upper surfaces of the support member 16 and the tension belt 17 are coplanar with the upper surface of the transfer member 6.

[0082] When the transfer component 6 drives the sealing ring to rise until the locating wheel 12 is in contact with the upper surface of the transfer component 6, the fourth cylinder 25 will actuate, causing the drive plate 24 to move upward along the length of the side plate 23. At this time, the coaxial wheel assembly 20 will lock at the end of the inclined groove 2402 away from the second horizontal groove 2401, allowing the connecting rod 19 to drive the support component 16 to rise stably. When the coaxial wheel assembly 20 rises to the end of the vertical groove 2301, the drive plate 24 will continue to move upward, allowing the coaxial wheel assembly 20 to move along the length of the inclined groove 2402 and the first horizontal groove 2302. During this process, the cylindrical spring 22 gradually releases its elastic potential energy, and the coaxial wheel assembly 20 moves laterally, allowing the support component 16 to move toward the locating wheel 12. When the axle wheel assembly 20 moves to one end of the inclined groove 2402 facing the second horizontal groove 2401, the support member 16 reaches its maximum displacement. At the same time, the first horizontal groove 2302 will completely overlap with the second horizontal groove 2401. Based on the above configuration, the support member 16 can move toward the chuck 12 when it is lifted to a certain height. The significance is that when the end of the sealing ring is lifted, due to the traction of the sealing ring's own weight, the end of the sealing ring tends to move toward the chuck 12. By making the support member 16 move toward the chuck 12, the support member 16 can provide stable support for the sealing ring, preventing the sealing ring from separating from the support member 16 due to the movement of the end of the sealing ring, thus making it impossible to tension it when the chuck 12 moves.

[0083] When the two sets of rollers 12 move away from each other, they act on the corresponding support members 16, causing the support members 16 to move in the opposite direction until the sealing ring is transferred from the support member 16 to the recessed part in the middle of the roller 12. Then the transfer member 6 moves downward and separates from the roller 12. During this process, the support member 16 will act on the side wall of the recessed part in the middle of the roller 12, causing the support members 16 to continue to move away from each other. At this time, the coaxial wheel set 20 can move along the first horizontal groove 2302 and the second horizontal groove 2302. The groove 2401 moves in the opposite direction until the support member 16 separates from the chuck 12. Then, the fourth cylinder 25 drives the drive plate 24 to move in the opposite direction, thereby resetting the support member 16. Based on the above configuration, when the two sets of chucks 12 move away from each other and separate from the transfer member 6, the support member 16 can be driven by the chuck 12, so that the sealing ring can be stably transferred from the support member 16 to the recess in the middle of the chuck 12. This ensures that the chuck 12 can effectively tension and transfer the sealing ring, thereby improving the detection efficiency.

[0084] As an embodiment of the present invention, a method for detecting large-size sealing rings using the aforementioned automatic feeding and detection device is also proposed, comprising the following steps:

[0085] Step 1: After the large-size sealing ring is produced, it will be placed on the carrier tray 1. At this time, the sliding component will move to transfer the large-size sealing ring on the carrier tray 1 to the transfer component 6. The transfer component 6 can squeeze the large-size sealing ring, so that the large-size sealing ring changes from a round shape to a flat round shape.

[0086] Step 2: The transfer component 6 moves upward until the lower end of the chuck 12 abuts against the upper end of the transfer component 6;

[0087] Step 3: The drive plate 24 moves upward, so that the coaxial wheel assembly 20 can drive the support kit to perform an upward movement first under the action of the guide groove and the drive groove, and then perform an action to move closer to the jack 12, so as to lift the two ends of the large-size sealing ring upward.

[0088] Step 4: Rotate the tensioning component to drive the two sets of jacks 12 to move away from each other, push the support kit to move in the opposite direction, and at the same time switch the large-size sealing ring onto the jacks 12;

[0089] Step 5: The transfer component 6 moves down, and at the same time the tensioning component rotates, causing the large-sized sealing ring tensioned between the two sets of calipers 12 to switch to the testing station.

[0090] 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.
