Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of visual detection, and particularly relates to an automobile ball cage production detection platform. BACKGROUND

[0002] The automobile ball cage retainer is a core component of a constant velocity joint, is widely applied to an automobile transmission system, and mainly functions to uniformly distribute steel balls between inner and outer raceways, ensure stable power transmission at different angles, and bear radial and axial loads in a vehicle driving process. The structure of the ball cage retainer is generally annular, and a plurality of windows are circumferentially distributed, and the whole is divided into key regions such as an inner ring surface, an outer ring surface, a window edge and an inner wall.

[0003] Quality detection of the ball cage retainer is a key link in a production process, mainly including precision detection, mechanical property detection and appearance quality detection; among them, the appearance quality detection mainly detects whether cracks, burrs, scratches, depressions, oxide skins and the like defects exist on the inner and outer ring surfaces, and the appearance detection of the inner and outer ring surfaces is a core link, the inner ring surface is matched with a joint shaft, and the outer ring surface is contacted with a shell, and any small defect can cause poor assembly or accelerated wear.

[0004] At present, a plurality of high-resolution industrial cameras are matched with customized light sources to shoot the inner ring surface and the outer ring surface of the retainer from different angles. Among them, the inner ring surface detection needs to focus on whether the matched surface matched with the shaft is flat and whether there are scratches; the outer ring surface detection needs to pay attention to whether the surface contacted with the shell has protrusions or depressions.

[0005] In a production environment, metal scraps, dust and the like impurities are easily attached to the surface of the retainer. These impurities can be shown in the image as follows: the gray value of the metal scrap is similar to that of the burr, and is misjudged as a surface protrusion defect; the dust particles form a shadow under the light source irradiation, and are identified as scratches or depressions; when the misjudgment is caused by the dust, qualified products are misremoved, production cost is increased, meanwhile, unqualified products are easily missed and flow out, and if the impurities cover fatal defects such as cracks, the retainer can be broken in a vehicle driving process, and a safety accident can be caused.

[0062] The second visual detection assembly is arranged on the top of the fixed block 1 on the left side;

[0063] In the embodiment, the first visual detection assembly comprises a rectangular groove 5; the rectangular groove 5 is arranged above the through hole 3, and the sliding plate 51 is slidably arranged in the rectangular groove 5;

[0064] The first industrial camera 52 is arranged in the sliding plate 51, and the shooting direction of the first industrial camera 52 is upward; the first industrial camera 52 is provided with light sources on both sides, and the first industrial camera 52 and the light sources are located in the rectangular groove 5 in the initial state;

[0065] The first cylinder 53 is arranged on the back of the vertical plate 2 on both sides of the sliding plate 51, and the extension rod of the first cylinder 53 is fixedly connected with the sliding plate 51;

[0066] The second visual detection assembly comprises a U-shaped plate 54; the U-shaped plate 54 is slidably arranged on the top of the fixed block 1 on the left side, and the U-shaped plate 54 is driven by the fourth cylinder 55; the second industrial camera 56 is arranged on the inner three surfaces of the U-shaped plate 54, and the light sources are arranged on both sides of the three second industrial cameras 56;

[0067] The fixing assembly comprises an arc plate 21; the arc plate 21 is fixedly arranged on the top of the vertical plate 2; the hydraulic cylinder 22 is arranged on the arc plate 21; the extension plate 23 is fixedly arranged on the extension rod of the hydraulic cylinder 22;

[0068] The two opposite mounting plates 24 are arranged on the bottom of the extension plate 23, the second roller 25 is rotatably arranged between the two mounting plates 24, the second roller 25 corresponds to the first roller 12, and the second roller 25 is driven by the first motor 26.

[0069] In the implementation, when the retainer 13 is detected, the retainer 13 is placed above the two first rollers 12 by the mechanical hand, and the retainer 13 is erected on the two first rollers 12, then the hydraulic cylinder 22 is controlled to extend, the extended hydraulic cylinder 22 pushes the extension plate 23 to move downward, the downward moving extension plate 23 drives the mounting plate 24 and the second roller 25 to move downward, the downward moving second roller 25 gradually approaches the arc surface on the top of the retainer 13, and finally the second roller 25 is attached to the top of the retainer 13, so that the retainer 13 is fixed between the first roller 12 and the second roller 25;

[0070] Specifically, since the cleaning layer 31 is concentrically arranged with the holder 13 in the initial state, when the holder 13 is fixed, the second cylinder 35 is controlled to retract, and the retracted second cylinder 35 drives the guide pipe 33, the guide rod 32, the cleaning layer 31 and the second motor 34 to move, the cleaning layer 31 gradually extends out of the through hole 3 and gradually extends into the holder 13, when the cleaning layer 31 is located in the inner ring of the holder 13, the electric push rod 14 is controlled to extend, and the hydraulic cylinder 22 is controlled to retract, the extended electric push rod 14 pushes the moving block 11 to move upwards along the two fixed blocks 1 and the vertical plate 2, and at the same time, the hydraulic cylinder 22 gradually retracts to adapt to the moving distance of the holder 13, when the electric push rod 14 extends to the limit position, the hydraulic cylinder 22 stops retracting, and in the process of moving the holder 13 upwards, the hydraulic cylinder 22 gradually approaches the cleaning layer 31, and finally the cleaning layer 31 is attached to the inner ring of the holder 13;

[0071] More specifically, when the moving block 11 moves upwards to the end, the third cylinder 43 is controlled to extend, the third cylinder 43 pushes the sliding chamber 41 to slide upwards in the chute 4, and at the same time drives the cleaning belt 42 and the third motor to move, when the third cylinder 43 extends to the limit, the cleaning belt 42 is attached to the outer ring of the holder 13 at this time, and at the same time, the cleaning belt 42 is attached to the side of the holder 13, then the first motor 26 is controlled to rotate, thereby driving the second roller 25 to rotate, the rotating second roller 25 pushes the holder 13 to rotate clockwise between the first roller 12 and the second roller 25, when the rotating holder 13 passes through the cleaning layer 31 and the cleaning belt 42, the cleaning layer 31 cleans the inner ring of the holder 13 at this time, and the cleaning belt 42 cleans the outer ring of the holder 13;

[0072] Then, the second motor 34 and the third motor are controlled to rotate, the rotating second motor 34 drives the cleaning layer 31 to rotate counterclockwise, and the rotating third motor drives the cleaning belt 42 to rotate clockwise, in the process of rotating the cleaning layer 31, the inner ring of the holder 13 is cleaned, and in the process of rotating the cleaning belt 42, the outer ring of the holder 13 is cleaned, since the cleaning belt 42 is attached to the side of the holder 13, the side of the holder 13 can be cleaned, and then the holder 13 can be visually detected;

[0073] Further, in the visual inspection of the retainer 13, the first cylinder 53 is controlled to contract, and the fourth cylinder 55 is controlled to extend. The contracting first cylinder 53 drives the sliding plate 51 to move, and the sliding plate 51 drives the first industrial camera 52 and the light sources on both sides to gradually slide out of the rectangular groove 5 and gradually move to the inner circle of the retainer 13 and above the cleaning layer 31. The extending fourth cylinder 55 drives the U-shaped plate 54 to move and gradually approach the retainer 13. When the fourth cylinder 55 extends to the limit position, the retainer 13 is partially located in the U-shaped plate 54, and the three second industrial cameras 56 in the U-shaped plate 54 correspond to the outer circle and the two sides of the retainer 13. At this time, the retainer 13 is continuously controlled to rotate slowly. In the process of rotation, the first industrial camera 52 and the three second industrial cameras 56 respectively shoot the inner circle, the outer circle and the side of the retainer 13. Since the retainer 13 is rotating, the first industrial camera 52 and the second industrial camera 56 can shoot the rotating retainer 13 multiple times, so as to comprehensively shoot different positions of the retainer 13. The shot image is transmitted to the computer for image processing and analysis, so as to identify whether there is a defect on the retainer 13. If the computer has identified that there is a defect on the retainer 13 after the retainer 13 rotates one round, the retainer 13 is continuously controlled to rotate one round or even two rounds, and then shot again and processed and analyzed again. After the retainer 13 is shot again, if the defect existing in the first shot no longer exists on the retainer 13, it can be considered that the defect existing in the first shot is caused by impurities and has been cleaned. After the retainer 13 is shot again, if the defect existing in the first shot still exists on the retainer 13, it can be considered that the defect existing in the first shot is real.

[0074] Subsequently, the first cylinder 53 is controlled to extend, and the extending first cylinder 53 drives the sliding plate 51 to return to the initial state. After the sliding plate 51 moves out of the retainer 13, the electric push rod 14, the hydraulic cylinder 22 and the third cylinder 43 are controlled to contract. The third cylinder 43 drives the sliding block 41 and the cleaning belt 42 to gradually enter the inclined groove 4 and return to the initial state. The hydraulic cylinder 22 drives the second roller 25 to move away from the retainer 13. The electric push rod 14 drives the moving block 11 to move downward and return to the initial state, and drives the retainer 13 to return to the initial state. After the retainer 13 returns, the cleaning layer 31 is concentric with the retainer 13 again. Subsequently, the second cylinder 35 is controlled to extend, and the extending second cylinder 35 drives the guide pipe 33, the guide pipe 33 and the cleaning layer 31 to return to the initial state. Subsequently, according to the detection result, the retainer 13 is taken down by the mechanical hand, the retainer 13 with defects is rejected, and the retainer 13 without defects is collected.

[0075] In general, by cleaning the inner ring of the retainer 13 with the cleaning layer 31, the impurities inside the retainer 13 can be cleaned, by cleaning the outer ring and the side of the retainer 13 with the cleaning belt 42, the impurities on the outer ring and the side of the retainer 13 can be cleaned, and then the cleaned retainer 13 is detected by the first industrial camera 52 and the second industrial camera 56, so that the presence of impurities on the retainer 13 during detection of the retainer 13 can be avoided, the presence of impurities can interfere with detection, and misjudgment is easy to occur, and part of the impurities blocks the defect position, so that the missed detection is easy to occur;

[0076] Meanwhile, by controlling the rotation of the retainer 13 multiple times, the retainer 13 is detected during multiple rotations, so that the retainer 13 is cleaned again after being detected once, and the cleaned retainer 13 is detected twice or even three times, so that it can be verified twice or three times. Through multiple verifications, the comprehensiveness of the retainer 13 detection can be ensured, the problem of qualified products being rejected or defects being missed due to impurities misjudgment in detection is further solved, and the reliability of the detection result is greatly improved.

[0077] As an embodiment of the present application, the bottom of the sliding chamber 41 is closed;

[0078] The first air pipe 44 is installed at the bottom of the sliding chamber 41, and the first air pipe 44 is in communication with an external dust collector; the side of the moving block 11 facing the sliding chamber 41 is provided with a missing groove 111, and the groove bottom of the missing groove 111 is a slope;

[0079] In this embodiment, the through hole 3 is provided with an oval chamber 36, and the cleaning layer 31 is located in the oval chamber 36, and the conduit 33 is fixed on the oval chamber 36;

[0080] The bottom of the oval chamber 36 is provided with a leakage groove 37; the length of the leakage groove 37 is slightly greater than the width of the retainer 13; the two sides of the leakage groove 37 are fixed with arc blocks 38;

[0081] The side of the oval chamber 36 facing the conduit 33 is provided with an air duct 39, and the air duct 39 is in communication with the conduit 33; the second air pipe 331 is installed at the end of the conduit 33, and the second air pipe 331 is located below the conduit 33; the second air pipe 331 is in communication with an external dust collector;

[0082] In this embodiment, the cleaning layer 31 is spiral-shaped, and the spiral-shaped cleaning layer 31 adapts to the internal space of the oval chamber 36, and the diameter in the middle is greater than the diameters on both sides;

[0083] The outer ring surface of the cleaning layer 31 is fixedly connected with bristles, and the bristles extend into the leakage groove 37;

[0084] In the embodiment, the air groove 112 is arranged on the moving block 11 between the two first rollers 12;

[0085] The top of the air groove 112 is rounded, and the third air pipe 113 is arranged at the bottom of the air groove 112 and communicates with the external dust collector.

[0086] In the implementation, when the cleaning belt 42 is used to clean the outer ring surface of the retainer 13, the first air pipe 44 is communicated with the external dust collector, so that the gas in the sliding chamber 41 is sucked through the first air pipe 44, and the removed impurities are sucked into the sliding chamber 41 during the rotation of the cleaning belt 42, and then are guided out through the first air pipe 44. In this process, the impurities can be avoided from falling randomly and remaining on the detection workbench during the cleaning of the outer ring surface of the retainer 13 by the cleaning belt 42, so as to act on the new retainer 13 again. At the same time, since the slot 111 is arranged on the side of the moving block 11 facing the sliding chamber 41, when the sliding chamber 41 gradually extends, the sliding chamber 41 gradually extends into the slot 111, so as to limit the moving block 11, and avoid the shaking of the moving block 11 during the rotation of the retainer 13.

[0087] Specifically, since the cleaning layer 31 is arranged in the elliptical chamber 36, and the elliptical chamber 36 is fixedly connected with the guide pipe 33, when the cleaning layer 31 extends into the retainer 13, the elliptical chamber 36 is also arranged in the retainer 13. When the retainer 13 moves upward with the moving block 11, the leakage groove 37 at the bottom of the elliptical chamber 36 is aligned with the retainer 13, and part of the retainer 13 enters the leakage groove 37. When the retainer 13 moves to the limit position, part of the retainer 13 is arranged in the leakage groove 37. Since the arc-shaped blocks 38 are fixedly connected on both sides of the leakage groove 37, the retainer 13 can be guided during the upward movement of the retainer 13, so as to ensure that the retainer 13 is aligned with the leakage groove 37.

[0088] More specifically, when part of the retainer 13 is arranged in the leakage groove 37, since the second air pipe 331 communicates with the external dust collector, the gas in the guide pipe 33 and the elliptical chamber 36 can be sucked through the second air pipe 331. Since the cleaning layer 31 is in the shape of a spiral with a large diameter in the middle and small diameters on both sides, the retainer 13 can be cleaned on the inner ring and the removed impurities can be transported during the rotation of the cleaning layer 31. The transported impurities enter the air duct 39 and are then sucked out. In this process, the removed impurities can be avoided from remaining on the inner ring of the retainer 13 during the cleaning of the retainer 13, so as to reduce the risk of the retainer 13 adhering to the impurities, thereby reducing the reliability of the retainer 13 during the detection.

[0089] Further, since the outer ring surface of the spiral cleaning layer 31 is fixedly connected with the brush, when the retainer 13 drives the window existing in the retainer 13 to pass through the cleaning layer 31, the brush will extend into the window at this time, so that the interior of the window can be cleaned, and the existence of impurities in the window is avoided, and misjudgment may occur due to the existence of impurities during detection; since the air groove 112 is arranged in the moving block 11, and the third air pipe 113 installed at the bottom of the air groove 112 is in communication with the external dust collector, during the cleaning process of the inner ring of the retainer 13 and the window, if part of the impurities falls downward through the window, the suction force generated by the air groove 112 can suck the falling impurities into the air groove 112, and then the impurities are sucked out through the third air pipe 113, so that the impurities falling on the moving block 11 are avoided, and the risk that the part of the impurities still adheres to the retainer 13 is avoided.

[0090] As an embodiment of the present application, two first rollers 12 are arranged on both sides of the sliding groove 6;

[0091] Two baffles 61 are slidably arranged in the sliding groove 6; the baffle 61 extends to the detection workbench through the sliding groove 6 and is fixedly connected with the detection workbench; in the initial state, the baffle 61 extends above the arc-shaped groove and is located below the cleaning layer 31;

[0092] In the embodiment, the top and bottom of the sliding plate 51 are fixed with positioning plates 511;

[0093] The outer ring of the conduit 33 is fixed with a positioning ring 332;

[0094] In the embodiment, the top of the extension plate 23 is fixed with an isolation cover 27;

[0095] The mounting plate 24 is fixed in the isolation cover 27; the isolation cover 27 is transparent.

[0096] In the implementation, since the sliding groove 6 on both sides of the first roller 12 is provided with the baffle 61, in the initial state, the baffle 61 extends to the workbench, when the retainer 13 is placed above the moving block 11, the retainer 13 can be placed between the two baffles 61, so that the retainer 13 can be positioned and blocked, and the sliding of the retainer 13 on the first roller 12 is avoided; since the baffle 61 is fixed on the detection workbench, during the upward movement of the moving block 11, the baffle 61 will not move upward with the moving block 11, and the sliding groove 6 will slide along the baffle 61, when the moving block 11 moves to the limit position, the top of the baffle 61 is located in the sliding groove 6 at this time, so that the baffle 61 will not move upward with the moving block 11 and collide with the cleaning layer 31;

[0097] Specifically, since a positioning plate 511 is fixed on the slide plate 51 and a positioning ring 332 is fixedly connected to the outer ring of the guide tube 33, when the slide plate 51 and the guide tube 33 move, the positioning plate 511 and the positioning ring 332 move with the slide plate 51 and the guide tube 33 respectively. Then the positioning plate 511 and the positioning ring 332 will fit against the upright plate 2, thereby limiting the distance that the slide plate 51 and the guide tube 33 move, and preventing the cleaning layer 31 and the first industrial camera 52 from being unable to align with the retainer 13.

[0098] Furthermore, when the extension plate 23 moves down, it will cause the isolation cover 27 to move down. When the second roller 25 contacts the retainer 13, the side of the isolation cover 27 near the upright plate 2 is in contact with the top of the upright plate 2, the side of the isolation cover 27 near the right fixing block 1 is in contact with the top of the right fixing block 1, the side of the isolation cover 27 near the moving block 11 is in contact with the side of the moving block 11, and the side of the isolation cover 27 near the U-shaped plate 54 is in contact with the top of the U-shaped plate 54, without affecting the movement of the U-shaped plate 54. During this process, by sealing the retainer 13 during the test, external dust can be prevented from falling onto the retainer 13, which would affect the test process of the retainer 13.
