[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-7 This invention provides a technical solution: a sealing ring processing and sorting device based on industrial vision, including a screening structure 1, a pair of guiding structures 2 at the right end of the screening structure 1, the pair of guiding structures 2 being staggered and opposite each other at the right end of the screening structure 1, and a feeding structure 3 at the left end of the screening structure 1; the feeding structure 3 is used to centrally stack different sealing rings and realize automatic feeding, the screening structure 1 is used to carry the feeding sealing rings, and to move and transport the sealing rings in the center and distinguish them according to their thickness, and the guiding structure 2 is used to collect sealing rings of different thicknesses respectively.

[0028] As a preferred embodiment, the screening structure 1 further includes a first conveyor frame 11, a first conveyor belt assembly 12, a pair of supports 13, a pair of visual recognition cameras 14, a pair of first motors 15, a pair of centering arms 16, and a separating unit 17; the first conveyor belt assembly 12 is fixedly disposed at the top center of the first conveyor frame 11, the left end of the first conveyor frame 11 is symmetrically provided with flip-up openings 4 corresponding to the upper wall of the first conveyor belt assembly 12, the right end of the first conveyor frame 11 is provided with staggered discharge openings 5, one end of each pair of supports 13 is fixedly disposed on the upper wall of the first conveyor frame 11 and located at the left end of the discharge opening 5, and the other end of the supports 13 is located at the discharge opening. Above the center of section 5, a pair of visual recognition cameras 14 are fixedly mounted on the other end of the bracket 13, a pair of first motors 15 are fixedly mounted on the lower inner wall of the flipping opening 4, and a pair of centering arms 16 are fixedly mounted on the drive end of the first motors 15 at one end, with the other ends of the centering arms 16 being relatively inclined. The distinguishing unit 17 is fixedly mounted on the right end of the first conveyor frame 11 and is located above the first conveyor belt assembly 12. The first conveyor frame 11 supports the first conveyor belt assembly 12, the visual recognition cameras 14 on the bracket 13 perform imaging to determine the quantity, and the centering arms 16 center the sealing ring on the first conveyor belt assembly 12.

[0029] More specifically, one end of a pair of brackets 13 is fixed to the upper wall of the first conveyor frame 11 and located at the left end of the discharge port 5, and the other end extends to the upper part of the middle of the discharge port 5. A pair of visual recognition cameras 14 are fixed to the extended end of the brackets 13 to capture images of the sealing rings conveyed to the discharge port 5, and to determine their thickness parameters and count them through imaging. A pair of first motors 15 are fixed to the middle of the lower inner wall of the flipping port 4, and the driving end is fixedly connected to the centering arm 16. The other end of the centering arm 16 is relatively inclined to form a "V" shaped centering structure. When the sealing ring is conveyed to the left end of the first conveyor belt assembly 12, the inclined arm surfaces of the two centering arms 16 push the sealing ring to the middle of the first conveyor belt assembly 12 to achieve centering positioning.

[0030] As a preferred embodiment, the distinguishing unit 17 further includes an electric push rod 171, a stop arm 172, and a stop seat 173; one end of the electric push rod 171 is fixedly inserted through the upper rear wall of the first conveyor frame 11 and located on the left side of the discharge port 5; one end of the stop arm 172 is fixedly mounted on the telescopic end of the electric push rod 171, and the other end of the stop arm 172 is arc-shaped, corresponding to the right side of one of the discharge ports 5; the stop arm 172 is located above the first conveyor belt assembly 12; and the stop seat 173 has a triangular structure. The stop 173 is detachably mounted on the right end of the first conveyor frame 11 and is located above the first conveyor belt assembly 12. The rear side wall of the stop 173 is an inclined wall. Two corners of the stop 173 correspond to another discharge port 5, and the other corner of the stop 173 is close to one of the discharge ports 5. The stop arm 172 is raised and lowered by the electric push rod 171. The stop arm 172 blocks the thicker sealing ring and causes it to move to a limited position. The stop 173 blocks the thinner sealing ring and guides it.

[0031] More specifically, when the sealing ring is conveyed to the discharge port 5 by the first conveyor belt assembly 12, as the first conveyor belt assembly 12 moves, the side wall of the thicker sealing ring will contact the baffle arm 172, move along the baffle arm 172 with the help of the baffle arm 172, and can be removed from the discharge port 5; while the thinner sealing ring passes under the baffle arm 172 and contacts the side wall of the baffle seat 173 for limitation, so that it can be removed from the discharge port 5 on the other side, realizing screening of different thicknesses. The height of the baffle arm 172 can be adjusted by the electric push rod 171 according to the screening thickness.

[0032] As a preferred embodiment, the guiding structure 2 further includes a second conveyor frame 21, a second conveyor belt assembly 22, a guide plate 23, and a pair of brackets 24. The second conveyor frame 21 is located on the front right side of the first conveyor frame 11 and is opposite to one of the discharge ports 5. The second conveyor belt assembly 22 is fixedly mounted on the second conveyor frame 21. One end of the guide plate 23 is obliquely fixedly mounted on the upper right side of the second conveyor frame 21 and located behind the second conveyor belt assembly 22. The other end of the guide plate 23 is movably embedded in the discharge port 5, and the upper inner wall of the guide plate 23 corresponds to the first conveyor belt assembly 12. A pair of brackets 24 are symmetrically arranged on the left and right side walls of the other end of the guide plate 23, and the brackets 24 are detachably inserted into the left and right side walls of the discharge port 5 of the first conveyor frame 11. The guide plate 23 receives the sealing rings that are limited by the stop 173 or the stop arm 172, and slides the sealing rings onto the second conveyor belt assembly 22 for separate conveying or collection by the collection box 6.

[0033] More specifically, the sealing rings sorted by the sorting unit 17 fall from the discharge port 5 and slide along the inclined surface of the guide plate 23. Since the inner upper wall of the guide plate 23 is flush with the first conveyor belt assembly 12, the sealing rings have no drop transition, avoiding collision deformation. After the sealing rings slide to the end of the guide plate 23, they fall onto the second conveyor belt assembly 22 for transfer and movement. Alternatively, a collection box 6 can be placed on the second conveyor belt assembly 22 for storage.

[0034] As a preferred embodiment, the feeding structure 3 further includes a material box 31, a support arm 32, a third conveyor frame 33, and a feeding assembly 34. The material box 31 is fixedly installed on the left side of the first conveyor frame 11, and the material box 31 corresponds to the first conveyor belt assembly 12. The inner right side wall of the material box 31 is inclined to the left. One end of the support arm 32 is fixedly installed in the middle of the front side wall of the material box 31. The third conveyor frame 33 is L-shaped and is fixedly installed on the other end of the support arm 32. One end of the third conveyor frame 33 is inserted into the material box 31, and the other end of the third conveyor frame 33 is located above the right end of the first conveyor belt assembly 12. The feeding assembly 34 is movably installed on the third conveyor frame 33. The third conveyor frame 33 is fixed above the material box 31 by the support arm 32, and the feeding assembly 34 is carried by the third conveyor frame 33.

[0035] More specifically, the sealing rings are stacked in the material box 31. Due to the inclination of the right side wall, the sealing rings automatically slide to the left side of the bottom of the box. The feeding component 34 moves to the left along the third conveyor frame 33 into the material box 31. It inserts the sealing ring into the inner hole through the hanging rod 348 at its lower part. Then, as the second conveyor belt 347 rotates, the displacement changes to parallel and vertical inclination, suspending the sealing rings for material collection. Subsequently, the feeding component 34 moves to the right, conveying the sealing rings to the upper right end of the first conveyor belt component 12, where they fall and are placed by their own gravity.

[0036] As a preferred embodiment, the feeding assembly 34 further includes three conveyor rollers 341, a second motor 342, a pair of pulleys 343, a belt 344, a pair of first conveyor belts 345, several pad rollers 346, a second conveyor belt 347, several hanging rods 348, and a support unit 349. The three conveyor rollers 341 are respectively movably mounted at both ends and the middle of the third conveyor frame 33, and the three conveyor rollers 341 are arranged in a right-angled triangle. The second motor 342 is fixedly mounted in the middle of the third conveyor frame 33. The pair of pulleys 343 are respectively fixedly mounted on the drive end of the second motor 342 and on one of the conveyor rollers 341. The belts 344 are movably mounted on the pulleys 343. The pair of first conveyor belts 345 are respectively mounted on the three conveyor rollers 341 and are symmetrically located at both ends of the conveyor rollers 341. Several pad rollers 346 are equidistantly arranged on the first conveyor belts 345. 5. On the upper wall, the second conveyor belt 347 is fixedly fitted to the outside of the first conveyor belt 345, and the second conveyor belt 347 and the first conveyor belt 345 are fixed together by pad rollers 346. Several hanging rods 348 are equidistantly inclinedly arranged in the middle of the second conveyor belt 347. The supporting unit 349 is fixedly arranged on the third conveyor frame 33 and connected to the first conveyor belt 345. The second motor 342 drives the pulley 343, and the belt 344 realizes the transmission between the pulleys 343 and drives one of the conveyor rollers 341, thereby driving the first conveyor belt 345 to rotate. The pad rollers 346 drive the second conveyor belt 347 to rotate, realizing the reciprocating rotation of the hanging rods 348. The rotating hanging rods 348 enter the material box 31 and move out of the material box 31 to realize the automatic suspension of the sealing ring for picking up materials. Then, as they rotate, they fall onto the first conveyor belt assembly 12 to realize the loading.

[0037] More specifically, the right-angled triangle position setting of the three conveyor rollers 341 ensures that the first conveyor belt 345 forms a stable triangular transmission path to avoid slippage. The pad roller 346 ensures that the second conveyor belt 347 is fixed in a sandwich configuration. The inclined design of the hanging rod 348 makes the center of gravity stable when the sealing ring is suspended, provides a certain force when inserting the material, and allows it to automatically fall off when being placed.

[0038] As a preferred embodiment, the support unit 349 further includes a boom 3491, a shaft frame 3492, and several guide shafts 3493. One end of the boom 3491 is fixedly mounted on the third conveyor frame 33, and the boom 3491 is located in the middle of the first conveyor belt 345. The shaft frame 3492 is fixedly mounted on the other end of the boom 3491, and the shaft frame 3492 is arc-shaped. Several bearings are arranged at equal intervals inside the shaft frame 3492. Several guide shafts 3493 are respectively fixed to the bearings that pass through the middle of the shaft frame 3492, and both ends of the guide shafts 3493 are located below the first conveyor belt 345, and both ends of the guide shafts 3493 are close to the pad rollers 346. The boom 3491 supports the shaft frame 3492, and the guide shafts 3493 arranged along the arc on the shaft frame 3492 carry the first conveyor belt 345, limiting and guiding the first conveyor belt 345.

[0039] More specifically, when the first conveyor belt 345 rotates with the conveyor roller 341, its inner surface contacts the cylindrical surface of the guide shaft 3493. The guide shaft 3493 rotates freely within the shaft frame 3492 through the bearing, forming rolling support, reducing the running resistance of the conveyor belt. Furthermore, the guide shaft 3493 limits the first conveyor belt 345, enabling the first conveyor belt 345 to be guided, ensuring that the first conveyor belt 345 can be conveyed without contact above the first conveyor belt assembly 12.

[0040] As a preferred embodiment, the second conveyor belt 347 and the first conveyor belt 345 between the guide shaft 3493 and one end of the third conveyor frame 33 are inclined to the lower left, and the inclination angle of the second conveyor belt 347 between the guide shaft 3493 and one end of the third conveyor frame 33 is the same as the inclination angle of the right side wall inside the material box 31.

[0041] As a preferred embodiment, one end of the second conveyor belt 347 is inserted into the hopper 31, and the other end of the second conveyor belt 347 is located above the left end of the first conveyor belt assembly 12.

[0042] As a preferred option, the collection box 6 is detachably mounted on the second conveyor belt assembly 22.

[0043] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0044] S1. Place the sealing rings into the material box 31. Through the inclined wall of the right side of the material box 31, the sealing rings will accumulate at the bottom left side of the material box 31. Then, by starting the second motor 342 in the feeding assembly 34, one of the pulleys 343 will be driven to rotate. With the help of the belt 344, the transmission between the two pulleys 343 will be realized, thereby driving one of the conveyor rollers 341 to rotate on the third conveyor frame 33, thereby driving the symmetrically arranged first conveyor belt 345 to rotate.

[0045] S2. Since the first conveyor belt 345 is supported by three conveyor rollers 341 forming a right-angled triangle, and the support unit 349 provided along the middle of the long side limits the first conveyor belt 345 to prevent the hanging rod 348 located above the first conveyor belt assembly 12 from contacting the first conveyor belt assembly 12, and the support unit 349 and the second conveyor belt 347 in the material box 31 are in an inclined state, and the inclination of the second conveyor belt 347 is the same as the inclination of the right side wall inside the material box 31, the second conveyor belt 347 can be inserted into the material box 31 for rotational conveying.

[0046] S3. The first conveyor belt 345 is connected to the second conveyor belt 347 by the pad roller 346, so that when the second conveyor belt 347 rotates, it can be effectively limited by the support unit 349 and drive the hanging rod 348 to rotate.

[0047] S4. As the first conveyor belt 345 rotates, the guide shaft 3493 is forced to rotate on the shaft frame 3492 supported by the boom 3491 for fitting and conveying.

[0048] S5. When the hanging rod 348 enters the material box 31 from the support unit 349, the end of the hanging rod 348 is inserted into the material box 31 at a downward angle. When the hanging rod 348 passes the conveyor roller 341, the hanging rod 348 is flipped with the conveyor and tilts upward after passing the conveyor roller 341, so that the sealing ring can be automatically fitted on the hanging rod 348 for feeding.

[0049] S6. As the second conveyor belt 347 rotates, the sealing ring moves to the upper left end of the first conveyor belt assembly 12 in the screening structure 1. After another conveyor roller 341 rotates, the sealing ring falls onto the first conveyor belt assembly 12 supported by the first conveyor frame 11 due to its own weight.

[0050] S7. By starting the first conveyor belt assembly 12 to convey to the right, the sealing ring is centered by the blocking of the centering arm 16, and the different diameters of the sealing ring can also drive the first motor 15 in the flipping port 4 to adjust the flipping of the centering arm 16, thereby adjusting the spacing at the other end of the centering arm 16.

[0051] S8. After the sealing ring is conveyed in the center, if the sealing ring is thicker, the side wall of the sealing ring will contact the stop arm 172 in the separating unit 17, and move out from the front discharge port 5 by being limited by the stop arm 172 and moving along the stop arm 172 under force; if the sealing ring is thinner, the sealing ring will pass under the stop arm 172 and contact the stop seat 173, and move out from the rear discharge port 5 by being limited by the stop seat 173.

[0052] S9. After the sealing ring is removed from the discharge port 5, it will fall directly onto the guide plate 23 corresponding to the card holder 24, and slide into the second conveyor belt assembly 22 on the second conveyor frame 21 by the tilt of the guide plate 23. It will be transferred by the movement of the second conveyor belt assembly 22. Alternatively, the collection box 6 can be placed on the second conveyor belt assembly 22 to allow the sliding sealing ring to enter the collection box 6 for storage.

[0053] S10. When the sealing ring falls from the discharge port 5, it will be counted by the visual recognition camera 14 on the support arm 32, which helps to quantitatively transport the collection box 6, etc.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
