Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring testing technology, specifically a rubber sealing ring finished product testing device. Background Technology

[0002] Rubber sealing ring end face inspection is a process of quantitatively analyzing key parameters such as dimensional accuracy and surface defects of the sealing ring end face through non-contact optics. It aims to ensure its tight fit with mating parts and avoid sealing failure due to uneven end face or the presence of cracks, impurities, etc., thereby improving the reliability and service life of the product in high pressure, high temperature or corrosive environments.

[0003] When inspecting rubber rings using existing image inspection equipment, the inspection camera can usually only acquire an image of one side of the rubber ring. If the other side needs to be inspected, the rubber ring needs to be flipped over, which reduces the inspection efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a finished rubber sealing ring testing device, which effectively solves the problems mentioned in the background art.

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

[0006] A finished rubber sealing ring inspection device includes an inspection platform, a first inspection camera, and a second inspection camera. A circular high-transparency glass plate is mounted on the inspection platform via a drive mechanism, which rotates the circular high-transparency glass plate. The first inspection camera is mounted on the inspection platform to photograph the sealing ring from below. An inverted L-shaped support frame is fixed on the top of the inspection platform, and the second inspection camera is mounted on the support frame to photograph the sealing ring from above. A feeding mechanism is provided on one side of the inspection platform to feed the sealing ring onto the circular high-transparency glass plate. A discharging mechanism is provided on one side of the inspection platform located on the circular high-transparency glass plate to unload the inspected rubber ring from the circular high-transparency glass plate.

[0007] Therefore, by feeding the sealing ring onto a rotatable circular high-transparency glass plate, and setting a second detection camera and a first detection camera on the upper and lower sides of the circular high-transparency glass plate respectively, the first detection camera takes a picture of the sealing ring from the bottom when the sealing ring rotates past the first detection camera, and the second detection camera takes a picture of the sealing ring from the top when the sealing ring rotates past the second detection camera, thus achieving double-sided detection of the sealing ring and effectively improving detection efficiency.

[0008] Furthermore, the feeding mechanism includes a guide plate A, a feeding trough A, a guide plate B, a feeding trough B, and a driving device. Feeding trough A and feeding trough B are sequentially installed on the side of the inspection table, and feeding trough B is installed above the inspection table. Guide plate A and guide plate B are respectively installed above the circular high-transparency glass plate through feeding trough B. The position of guide plate A corresponds to the position of feeding trough A, and the position of guide plate B corresponds to the position of feeding trough B. Guide plate B is located downstream of guide plate A. When feeding trough B drives guide plate A to feed and intercept and guide qualified rubber rings onto feeding trough A, feeding trough B drives guide plate B to retract and reset. When feeding trough B drives guide plate B to feed and intercept and guide unqualified rubber rings onto feeding trough B, feeding trough B drives guide plate A to retract and reset.

[0009] Furthermore, the drive device includes a motor, gears, and racks. A stand B is fixed on the testing platform, and a mounting plate is fixed on the stand B. The motor is fixed below the mounting plate, and the gear is fixed on the output shaft of the motor. U-shaped grooves are fixed on both sides of the motor below the mounting plate via connecting plates. Racks are slidably installed on both U-shaped grooves, and both racks mesh with the gears. Guide plate A is fixed on the end of one rack, and guide plate B is fixed on the end of the other rack.

[0010] Furthermore, the feeding mechanism includes a vertically fixed stand A on the testing table and an inclined feeding trough installed on top of the stand A.

[0011] Furthermore, a circular barrier is fixed to the circular high-transparency glass plate to prevent excessive impact from the sealing ring during feeding. A connecting rod is fixed below the feeding trough, and an arc-shaped outer barrier is fixed to the bottom end of the connecting rod. There is a gap between the outer barrier and the upper surface of the circular high-transparency glass plate.

[0012] Furthermore, the first and second detection cameras are arranged in a staggered manner.

[0013] Furthermore, the lower surfaces of both guide plate A and guide plate B are positioned higher than the upper surface of the circular high-transparency glass plate.

[0014] Furthermore, the drive mechanism includes a drive motor and a shaft. The drive motor is fixed on the testing table, and the shaft is fixed on a circular high-transparency glass plate. The bottom end of the shaft is fixedly connected to the output shaft of the drive motor.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] This invention achieves double-sided inspection of the sealing ring by feeding it onto a rotatable circular high-transparency glass plate, and by setting a second inspection camera and a first inspection camera on the upper and lower sides of the circular high-transparency glass plate, respectively. When the sealing ring rotates past the first inspection camera, the first inspection camera takes a picture of the sealing ring from the bottom, and when the sealing ring rotates past the second inspection camera, the second inspection camera takes a picture of the sealing ring from the top, thus achieving double-sided inspection of the sealing ring and effectively improving inspection efficiency.

[0017] This invention arranges a feeding mechanism, a first detection camera, a second detection camera, and a discharging mechanism sequentially around a rotatable circular high-transparency glass plate. This allows for the sequential feeding, lower detection, upper detection, and discharging of rubber rings along the rotation path of the circular high-transparency glass plate, ensuring the continuity of the detection process. No machine stoppage is required during detection intervals. Furthermore, after detection, the rubber rings are automatically sorted and unloaded based on the detection results, further improving detection efficiency.

[0018] This invention utilizes a circular barrier to prevent the rubber ring from being excessively impacted and moving away when it slides from the feeding groove onto the circular high-transparency glass plate. Since the sealing ring is elastic, it may rebound when it hits the circular barrier. By setting an outer barrier below the feeding groove, the rebounding sealing ring can be blocked and limited, thus effectively limiting the sealing ring within the imaging and detection area and improving detection accuracy.

Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0026] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] Please see Figures 1-4 This utility model provides a finished rubber sealing ring testing device, including a testing platform 1, a first testing camera 3, and a second testing camera 4. A circular high-transparency glass plate 2 is mounted on the top of the testing platform 1 via a drive mechanism. The drive mechanism is used to rotate the circular high-transparency glass plate 2. The first testing camera 3 is mounted on the testing platform 1 and is used to photograph the sealing ring from below. An inverted L-shaped support frame 11 is fixed on the top of the testing platform 1. The second testing camera 4 is mounted on the support frame 11 and is used to photograph the sealing ring from above. A feeding mechanism 5 is provided on one side of the testing platform 1. The feeding mechanism 5 is used to feed the sealing ring onto the circular high-transparency glass plate 2. A discharging mechanism 6 is provided on one side of the testing platform 1 located on the circular high-transparency glass plate 2 and is used to unload the tested rubber ring from the circular high-transparency glass plate 2.

[0028] When using this testing device to further inspect the finished sealing rubber rings, the drive mechanism drives the circular high-transparency glass plate 2 to rotate, and the feeding mechanism 5 feeds the sealing ring onto the circular high-transparency glass plate 2, so that the sealing ring rotates with the circular high-transparency glass plate 2. When the sealing ring rotates past the first inspection camera 3, the first inspection camera 3 takes a picture of the sealing ring from the bottom. When the sealing ring rotates past the second inspection camera 4, the second inspection camera 4 takes a picture of the sealing ring from the top, thus realizing double-sided inspection of the sealing ring. After the inspection is completed, the unloading mechanism 6 unloads the sealing ring from the circular high-transparency glass plate 2.

[0029] This device loads the sealing ring onto a rotatable circular high-transparency glass plate 2, and sets a second detection camera 4 and a first detection camera 3 on the upper and lower sides of the circular high-transparency glass plate 2, respectively. When the sealing ring rotates past the first detection camera 3, the first detection camera 3 takes a picture of the sealing ring from the bottom, and when the sealing ring rotates past the second detection camera 4, the second detection camera 4 takes a picture of the sealing ring from the top, thus realizing double-sided detection of the sealing ring and effectively improving detection efficiency.

[0030] Specifically, the feeding mechanism 6 includes a guide plate A61, a feeding trough A62, a guide plate B63, a feeding trough B64, and a drive device 65. Feeding troughs A62 and B64 are sequentially installed on the side of the inspection table 1, and feeding trough B64 is installed above the inspection table 1. Guide plates A61 and B63 are respectively installed above the circular high-transparency glass plate 2 via feeding trough B64. The guide plate A61 corresponds to the feeding trough A62, and the guide plate B63... The position corresponds to the feeding chute B64, and the guide plate B63 is located downstream of the guide plate A61. When the feeding chute B64 drives the guide plate A61 to feed in order to intercept and guide the qualified rubber rings to the feeding chute A62, the feeding chute B64 drives the guide plate B63 to retract and reset. When the feeding chute B64 drives the guide plate B63 to feed in order to intercept and guide the unqualified rubber rings to the feeding chute B64, the feeding chute B64 drives the guide plate A61 to retract and reset.

[0031] The drive unit 65 includes a motor 653, a gear 654, and a rack 657. A stand B651 is fixed on the testing table 1, and a mounting plate 652 is fixed on the stand B651. The motor 653 is fixed below the mounting plate 652, and the gear 654 is fixed on the output shaft of the motor 653. U-shaped grooves 656 are fixed on both sides of the motor 653 below the mounting plate 652 via connecting plates 655. A rack 657 is slidably mounted on both U-shaped grooves 656, and both racks 657 mesh with the gear 654. A guide plate A61 is fixed on the end of one rack 657, and a guide plate B63 is fixed on the end of the other rack 657.

[0032] After the inspection is completed, when the rubber ring passes the inspection, the motor 653 drives the gear 654 to rotate forward. The rotating gear 654 meshes with the rack 657 on one side and drives the guide plate A61 to move forward. At the same time, it meshes with the rack 657 on the other side and drives the guide plate B63 to move backward. The guide plate A61 moves to above the circular high-transparency glass plate 2, which can block and guide the qualified rubber ring into the discharge groove A62. When the rubber ring passes the inspection, the motor 653 drives the gear 654 to rotate in the opposite direction. The rotating gear 654 meshes with the rack 657 on one side and drives the guide plate B63 to move forward. At the same time, it meshes with the rack 657 on the other side and drives the guide plate A61 to move backward. The discharge groove A62 moves to above the circular high-transparency glass plate 2, which can block and guide the qualified rubber ring into the discharge groove B64. This achieves the effect of classifying and discharging the rubber rings according to the inspection results.

[0033] By sequentially arranging a feeding mechanism 5, a first detection camera 3, a second detection camera 4, and a discharging mechanism 6 around a rotatable circular high-transparency glass plate 2, the rubber rings are sequentially fed, inspected from below, inspected from above, and discharged along the rotation path of the circular high-transparency glass plate 2. This ensures the continuity of the inspection process, eliminates the need to stop and wait between inspections, and automatically sorts and discharges the rubber rings based on the inspection results after inspection, further improving inspection efficiency.

[0034] Specifically, the feeding mechanism 5 includes a vertically fixed stand A51 on the inspection table 1 and an inclined feeding trough 52 installed on the top of the stand A51.

[0035] A circular barrier 21 is fixed on the circular high-transparency glass plate 2 to prevent the sealing ring from being over-impacted during feeding. A connecting rod 53 is fixed below the feeding trough 52. An arc-shaped outer perimeter 54 is fixed at the bottom of the connecting rod 53. There is a gap between the outer perimeter 54 and the upper surface of the circular high-transparency glass plate 2 to prevent the outer perimeter 54 from contacting the circular high-transparency glass plate 2.

[0036] The feeding trough 52 is inclined. The rubber ring slides on the feeding trough 52 to feed the rubber ring onto the circular high-transparency glass plate 2. By providing a circular barrier 21 on the circular high-transparency glass plate 2, when the rubber ring slides from the feeding trough 52 onto the circular high-transparency glass plate 2, the circular barrier 21 can block it and prevent the rubber ring from being excessively impacted and moving away.

[0037] Because the sealing ring is elastic, it may rebound when it hits the circular enclosure 21. By setting an outer perimeter 54 below the feeding trough 52, the rebounding sealing ring can be blocked and limited, thereby effectively limiting the sealing ring within the shooting detection area and improving the detection accuracy.

[0038] Specifically, the first detection camera 3 and the second detection camera 4 are arranged in a staggered manner to avoid mutual interference between the supplementary lighting on the two detection cameras.

[0039] Specifically, the lower surfaces of guide plates A61 and B63 are both set higher than the upper surface of the circular high-transparency glass plate 2 to prevent guide plates A61 or B63 from contacting the upper surface of the circular high-transparency glass plate 2 during feeding.

[0040] Specifically, the drive mechanism includes a drive motor 101 and a shaft 103. The drive motor 101 is fixed on the testing table 1, and the shaft 103 is fixed on the circular high-transparency glass plate 2. The bottom end of the shaft 103 is fixedly connected to the output shaft of the drive motor 101. When the drive motor 101 works, its output shaft can drive the shaft 103 and the circular high-transparency glass plate 2 to rotate, providing drive for the rotation of the circular high-transparency glass plate 2.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
