Description

Technical Field

[0001] This invention relates to the field of parts inspection technology, specifically a visual inspection device for bathroom towel rack end caps based on AI image screening. Background Technology

[0002] As the end accessory of a towel rack, the end cap's dimensions (such as diameter) must precisely match the bracket tube diameter or installation interface. Dimensional deviations may result in installation failure or loosening, affecting overall stability. A perfectly fitting end cap can prevent dust and insects from entering the tube, extending the product's lifespan.

[0003] Common plugs consist of a cylindrical sleeve and a mounting base, with relatively small dimensions for each component. Mass production often employs turning processes to manufacture plugs, effectively improving production efficiency. However, turning is prone to dimensional errors in large-scale production. Furthermore, collisions between parts during machining can cause defects such as chips on the plug surface. Therefore, after manufacturing, plugs require quality inspection to prevent defective products from entering the market.

[0004] Common quality inspections include size inspection, height step size inspection, shape contour inspection, round hole eccentricity inspection, lower end face defect inspection, chamfer size inspection, presence or absence of R-corners inspection, and presence or absence of rotten teeth inspection. Traditional inspection methods involve sampling inspection using calipers and manual visual inspection, which can control product quality to a certain extent, but the inspection efficiency and accuracy are not high. Therefore, visual inspection devices are often used for inspection in mass production.

[0005] Common visual inspection devices include a glass turntable, a high-precision probe, and an inspection system. They are typically located at the end of the plug manufacturing process. Processed plugs are fed one by one onto the glass turntable. As the turntable rotates, it displaces the plugs, which then pass through the detection range of the high-precision probe. The high-precision probe monitors the condition of the moving plugs and compares it with design values ​​through the inspection system to determine the plug's quality. Furthermore, the end of the visual inspection device includes a screening module to separate good and defective products, resulting in high inspection efficiency and accuracy.

[0006] Because the glass turntable is rotating when the plug is delivered to it, sliding friction occurs between the turntable and the plug. After prolonged operation, minor scratches inevitably appear on the turntable. When the detection light source passes through the turntable, these scratches interfere with the illumination of the light source (causing diffraction or interference), leading to errors in the detection results of the high-precision probe, which is detrimental to effective product quality control. Replacing the glass turntable is costly and delays production. Summary of the Invention

By cooperating with the intermittent rotation structure, the feeding structure, and the releasing structure, plugs can be smoothly placed onto the glass turntable when it is stationary. During placement, the relative sliding between the glass turntable and the plug is minimal, effectively reducing wear on the glass turntable and extending its service life. It avoids large errors in detection results due to significant wear on the glass turntable during prolonged operation, effectively improving detection accuracy. The intermittent rotation structure drives the glass turntable, feeding structure, and releasing structure to alternately move, ensuring a more orderly delivery of plugs. It also avoids interference from high-precision probes when detecting plug dimensions due to excessively large or small gaps between adjacent plugs, i.e., intermittent rotation combined with feeding... Timing control ensures a constant spacing between plugs, avoiding interference from reflected signals from adjacent plugs and thus improving detection accuracy. The orderly delivery of plugs facilitates the rational layout of the detection module, blowing module, and other structures, thereby improving detection efficiency. Furthermore, when the glass turntable is stationary, the device not only delivers plugs but also uses a high-precision probe to detect the quality of the delivered plugs. The relative stillness between the high-precision probe and the plugs reduces detection errors and avoids the computational burden on the detection module caused by dynamic detection, reducing software development costs. A detection signal is triggered when the glass turntable stops, ensuring that the detection data and position of each plug strictly correspond, facilitating defect tracing. The simultaneous execution of delivery, detection, and blowing actions during the turntable's stop phase shortens cycle time and avoids the operational burden caused by high-frequency actions, effectively improving detection efficiency and extending the device's lifespan.

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.

When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0064] Please see Figures 1-12 In this embodiment of the invention, a visual inspection device for bathroom towel rack plugs based on AI image screening includes a housing 1; a vibratory feeder module 2, a discharge port 101, and a waste port 102 are fixedly installed on the housing 1.

[0065] It also includes a glass turntable 4 rotatably mounted on the housing 1; a conveying track 201 is fixedly installed on the discharge end of the vibratory feeder module 2;

[0066] Inside the chassis 1, detection modules 3 are fixedly installed at equal intervals along the circumference of the glass turntable 4. The detection module 3 includes a high-precision probe 301.

[0067] A jetting module 5 is fixedly installed inside the casing 1; the jetting module 5 includes a jet pipe 501 that cooperates with the discharge port 101;

[0068] The chassis 1 is provided with an intermittent rotation structure that is fixedly connected to the glass turntable 4;

[0069] The end of the conveying track 201 is provided with a feeding structure and a releasing structure that cooperate with the intermittent rotation structure;

[0070] The feeding structure includes multiple sets of symmetrically arranged cross baffles 17 that are rotatably installed on the conveying track 201;

[0071] The release structure includes multiple sets of symmetrically arranged opening and closing plates 20 that are slidably mounted on the conveying track 201;

[0072] The intermittent rotation structure can drive the glass turntable 4 to rotate in order to perform the feeding action;

[0073] When the glass turntable 4 stops rotating, the intermittent rotation structure can drive the feeding structure and the release structure to move; the release structure will drive multiple sets of opening and closing plates 20 to move closer or further apart to perform the receiving and releasing actions; the feeding structure will drive multiple sets of cross baffles 17 to rotate to perform the feeding action; at the same time, the high-precision probe 301 will perform the detection action.

[0074] Taking the embodiment combining all the features described in this application as an example, when in use, the vibratory feeder module 2 can continuously convey the plug (bathroom towel rack plug) with the front of the plug facing upwards, and convey it into the machine box 1 through the conveying track 201.

[0075] With the cooperation of the feeding structure and the release structure, the conveyed plugs can be orderly placed on the glass turntable 4.

[0076] The intermittent rotation structure drives the glass turntable 4 to rotate intermittently, which in turn moves the plug along a circular trajectory toward the discharge port 101. Each rotation of the glass turntable 4 moves the plug a certain distance. When the glass turntable 4 stops rotating, the plug is positioned directly below the high-precision probe 301. At this point, the high-precision probe 301 can detect the size of the plug and compare the detected value with the design value through the detection module 3 to determine whether the plug is of acceptable quality.

[0077] As the plug moves along a circular trajectory toward the discharge port 101, it will move and stop several times under the influence of the intermittent rotating structure. During each stop, a high-precision probe 301 will detect the plug at different angles, thereby conducting comprehensive quality inspection to ensure product quality.

[0078] When all the test values ​​are within a reasonable range and the error between them and the design values ​​is not large, when the plug moves to the discharge port 101, the blowing module 5 will blow high-pressure air and release it through the jet pipe 501 to blow the plug so that it moves quickly to the discharge port 101 and is discharged through the discharge port 101.

[0079] When the error is large, when the plug is displaced to the discharge port 101, the blowing module 5 will not operate. The defective product will continue to move towards the waste port 102 under the drive of the intermittent rotating structure, and will eventually fall into the waste port 102 and be discharged through the waste port 102.

[0080] The intermittent rotation structure drives the glass turntable 4 to rotate, which in turn moves the plug. During the displacement, the plug passes through each detection module 3, and thus the high-precision probe 301 detects the plug from multiple angles in an orderly manner. Moreover, the detection is carried out while the glass turntable 4 is stationary, which reduces the error of the detection results and improves the effective control of product quality.

[0081] When the glass turntable 4 is stationary, the intermittent rotation structure will drive the feeding structure and the release structure to move. The release structure will drive the opening and closing plates 20 to move closer together to reduce the distance between them, thus facilitating the receiving of the plug. At this time, the feeding structure does not move. When the opening and closing plates 20 move closer together to the end of their stroke, the cross baffle 17 will rotate synchronously, thereby pushing the plug onto the opening and closing plates 20 and isolating the next plug. After that, the cross baffle 17 remains stationary, and the opening and closing plates 20 will move away from each other to gradually increase the distance, thereby smoothly placing the plug onto the glass turntable 4.

[0082] After the feeding and releasing structures complete the feeding, receiving, and releasing actions, the intermittent rotating structure will drive the glass turntable 4 to rotate again, thereby displacing the inserted plug.

[0083] By coordinating the intermittent rotation structure with the feeding and releasing structures, the plug can be smoothly placed onto the glass turntable 4 when it is stationary. During the placement process, the relative sliding between the glass turntable 4 and the plug is small, which can effectively reduce the wear of the glass turntable 4 and avoid large errors in the detection results due to excessive wear of the glass turntable 4 under long-term operation; thus, it can effectively improve the detection accuracy.

[0084] In another embodiment of the present invention, the intermittent rotation structure includes a large turntable 9 and a small turntable 10 rotatably mounted on the housing 1; the large turntable 9 is fixedly connected to the glass turntable 4; the small turntable 10 cooperates with the feeding structure and the release structure; a plurality of first toothed blocks 901 are fixedly mounted on the large turntable 9; a plurality of second toothed blocks 1001 are fixedly mounted on the small turntable 10; a sliding plate 8 is slidably fitted on the housing 1; and a plurality of sets of sliding plates 901 and second toothed blocks 1001 are slidably fitted on both sides of the sliding plate 8. The drive gear block 803 is matched; multiple sets of small springs 802 are provided inside the slide plate 8; the two ends of the small springs 802 respectively abut against the slide plate 8 and the drive gear block 803; multiple sets of fixing sleeves 11 are fixedly installed on the housing 1; a limiting gear block 12 that matches both the first gear block 901 and the second gear block 1001 is slidably fitted inside the fixing sleeve 11; a large spring 1101 is provided inside the fixing sleeve 11; the two ends of the large spring 1101 abut against the limiting gear block 12 and the fixing sleeve 11 respectively.

[0085] In another embodiment of the present invention, the intermittent rotation structure further includes a motor 6 fixedly installed inside the housing 1; a connecting rod 7 is fixedly installed on the output end of the motor 6; a sliding column 701 is fixedly installed on one end of the connecting rod 7; and a sliding groove 801 is provided on the sliding plate 8 to slide and engage with the sliding column 701.

[0086] Taking the embodiment combining all the features described in this application as an example, when the motor 6 is activated, it will drive the connecting rod 7 to rotate, thereby driving the slide column 701 to rotate; during the rotation of the slide column 701, it will slide in the slide groove 801 and squeeze the slide plate 8, thereby driving the slide plate 8 to move horizontally back and forth.

[0087] One side of the drive tooth block 803 is a flat surface, and the other side is a slope surface; the first tooth block 901, the second tooth block 1001, and the limiting tooth block 12 all have flat surface and slope surface features.

[0088] The slopes of the drive blocks 803 on both sides of the slide plate 8 face opposite directions. The slopes of the first block 901 and the second block 1001 face the same direction.

[0089] When the slide plate 8 slides away from the connecting rod 7, the flat surface of the drive tooth block 803 near the small turntable 10 will abut against the flat surface of the second tooth block 1001, thereby driving the small turntable 10 to rotate. During the rotation, the slope of the second tooth block 1001 will cooperate with the slope of the limiting tooth block 12, thereby squeezing the limiting tooth block 12 and driving the limiting tooth block 12 to slide inward in the fixed sleeve 11 to compress the large spring 1101. When the second tooth block 1001 passes the limiting tooth block 12, the elastic force of the large spring 1101 will drive the limiting tooth block 12 to slide outward in the fixed sleeve 11 to reset.

[0090] The slope of the drive tooth block 803 near the large turntable 9 will cooperate with the slope of the first tooth block 901, and the flat surface of the first tooth block 901 will cooperate with the flat surface of another limiting tooth block 12 to restrict the rotation of the large turntable 9. During the cooperation between the first tooth block 901 and the drive tooth block 803, their slopes will cooperate with each other. During the cooperation, the drive tooth block 803 will slide inward in the slide plate 8 to compress the small spring 802. When the drive tooth block 803 passes the first tooth block 901, the elastic force of the small spring 802 will drive the drive tooth block 803 to return to its original position.

[0091] When the skateboard 8 slides away from the link 7, the large turntable 9 does not rotate, while the small turntable 10 rotates.

[0092] When the skateboard 8 slides towards the link 7, the large turntable 9 rotates while the small turntable 10 does not rotate.

[0093] When the large turntable 9 rotates, it will cause the glass turntable 4 to rotate at a certain angle, thereby causing the plug to move a certain distance. When the small turntable 10 rotates, it will cause the feeding structure and the releasing structure to move, thereby placing the plug onto the glass turntable 4.

[0094] When the intermittent rotating structure operates, it first drives the feeding and releasing structures to place the first plug onto the glass turntable 4. Then, it drives the glass turntable 4 to rotate, transferring the first plug to the first detection module 3. When the first plug reaches the first detection module 3, the intermittent rotating structure will restart the feeding and releasing structures to place the second plug onto the glass turntable 4. Then, it will restart the rotation of the glass turntable 4 to transfer the first plug to the next detection module 3, and the second plug to the first detection module 3.

[0095] The intermittent rotation structure drives the glass turntable 4 to alternately move with the feeding and releasing structures, which can transport the plugs in a more orderly manner. This avoids interference when the high-precision probe 301 detects the plug size due to excessively large or small gaps between adjacent plugs, thereby improving detection accuracy. The orderly transport of plugs also facilitates the reasonable layout of the detection module 3, the blowing module 5, and other structures, thereby improving detection efficiency.

[0096] In another embodiment of the present invention, a rotating shaft 13 is fixedly installed on the small turntable 10; the rotating shaft 13 has multiple sets of first inclined grooves 1301 and second inclined grooves 1302 that are interconnected end to end; a lifting sleeve 14 that is slidably fitted with the chassis 1 is sleeved on the rotating shaft 13; a protruding post 1409 that is slidably fitted with the first inclined groove 1301 and the second inclined groove 1302 is fixedly installed inside the lifting sleeve 14; a first rotating sleeve 15 that is rotatably connected to the chassis 1 is sleeved on the lifting sleeve 14. The first rotating sleeve 15 is connected to the feeding structure via a belt; the second rotating sleeve 16 is connected to the release structure via a belt; a first protruding post 1501 is fixed on the first rotating sleeve 15; a second protruding post 1601 is fixedly installed on the second rotating sleeve 16; the lifting sleeve 14 is provided with multiple sets of first rotating grooves that slide and engage with the first protruding post 1501 and a second rotating groove that slides and engages with the second protruding post 1601.

[0097] In another embodiment of the present invention, the first rotating groove group includes a first vertical groove 1401, a third inclined groove 1402, a second vertical groove 1403, and a fourth inclined groove 1404; wherein, one end of the first vertical groove 1401 is connected to one end of the third inclined groove 1402; the other end of the third inclined groove 1402 is connected to one end of the second vertical groove 1403; the other end of the second vertical groove 1403 is connected to one end of the fourth inclined groove 1404; and the other end of the fourth inclined groove 1404 is connected to the first vertical groove 1401 in another set of the first rotating groove group.

[0098] The second rotating groove group includes a third vertical groove 1405, a fifth inclined groove 1406, a fourth vertical groove 1407, and a sixth inclined groove 1408; wherein, one end of the third vertical groove 1405 is connected to one end of the fifth inclined groove 1406; the other end of the fifth inclined groove 1406 is connected to the fourth vertical groove 1407; one end of the fourth vertical groove 1407 is connected to one end of the sixth inclined groove 1408; and the other end of the sixth inclined groove 1408 is connected to the other end of the third vertical groove 1405.

[0099] Taking the embodiment combining all the features described in this application as an example, when the small turntable 10 rotates, it will drive the rotating shaft 13 to rotate, thereby driving the first inclined groove 1301 and the second inclined groove 1302 to rotate, thereby driving the protruding column 1409 to slide in the first inclined groove 1301 and the second inclined groove 1302.

[0100] When the protruding column 1409 slides from the second inclined groove 1302 to the first inclined groove 1301, it can drive the lifting sleeve 14 to gradually approach the small turntable 10.

[0101] At this time, the first protruding post 1501 first slides in the first vertical groove 1401 towards the third inclined groove 1402, and the first rotating sleeve 15 does not rotate; then it slides in the third inclined groove 1402 towards the second vertical groove 1403, thereby driving the first rotating sleeve 15 to rotate. The second protruding post 1601 first slides in the third vertical groove 1405 towards the fifth inclined groove 1406, and the second rotating sleeve 16 does not rotate. Then it slides in the fifth inclined groove 1406 towards the fourth vertical groove 1407, thereby driving the second rotating sleeve 16 to rotate in the forward direction; then it slides in the fourth vertical groove 1407 away from the sixth inclined groove 1408, and the second rotating sleeve 16 does not rotate.

[0102] During this process, when the second protruding column 1601 slides in the third vertical groove 1405 and the fifth inclined groove 1406, the first protruding column 1501 slides in the first vertical groove 1401; thereby driving the release structure to move the opening and closing plates 20 closer to each other, so as to facilitate the receiving action; the feeding structure does not move.

[0103] When the second protruding post 1601 slides in the fourth vertical groove 1407, the first protruding post 1501 slides in the third inclined groove 1402; thereby driving the feeding structure to move, but not the releasing structure to move. During this process, the cross baffle 17 rotates at a certain angle, but the feeding action is not completed.

[0104] Then, when the protruding column 1409 slides from the first inclined groove 1301 to the second inclined groove 1302, it can drive the lifting sleeve 14 to gradually move away from the small turntable 10.

[0105] During this process, the first protruding post 1501 will first slide in the second vertical groove 1403 towards the fourth inclined groove 1404, at which time the first rotating sleeve 15 will not rotate; then the first protruding post 1501 will slide in the fourth inclined groove 1404 towards the first vertical groove 1401, and the third inclined groove 1402 is inclined in the opposite direction to the fourth inclined groove 1404, thereby driving the first rotating sleeve 15 to continue rotating; then, the first protruding post 1501 will slide in the first vertical groove 1401 away from the third inclined groove 1402, at which time the first rotating sleeve 15 will not rotate.

[0106] The second protruding post 1601 will first slide in the fourth vertical groove 1407 towards the sixth inclined groove 1408, at which time the second rotating sleeve 16 will not rotate; then the second protruding post 1601 will slide in the sixth inclined groove 1408 towards the third vertical groove 1405; the fifth inclined groove 1406 and the sixth inclined groove 1408 have the same inclination direction, thereby driving the second rotating sleeve 16 to rotate in the opposite direction.

[0107] During this process, when the first protruding post 1501 slides in the second vertical groove 1403 and the fourth inclined groove 1404, the second protruding post 1601 slides in the fourth vertical groove 1407. Therefore, the first rotating sleeve 15 rotates, while the second rotating sleeve 16 does not rotate, allowing the feeding structure to continue performing the feeding action. When the first protruding post 1501 slides in the first vertical groove 1401, the second protruding post 1601 slides in the sixth inclined groove 1408. Therefore, the first rotating sleeve 15 does not rotate, while the second rotating sleeve 16 rotates in the opposite direction, thereby causing the opening and closing plates 20 to move away from each other to perform the release action.

[0108] By coordinating the intermittent rotation structure with the feeding and releasing structures, the plug can be smoothly placed onto the glass turntable 4 when it is stationary. During the placement process, the relative sliding between the glass turntable 4 and the plug is small, which can effectively reduce the wear of the glass turntable 4 and avoid large errors in the detection results due to excessive wear of the glass turntable 4 under long-term operation; thus, it can effectively improve the detection accuracy.

[0109] In another embodiment of the present invention, the feeding structure further includes a first synchronous gear 1701 fixedly installed on the cross baffle 17; and two first synchronous gears 1701 mesh with each other; and one of the cross baffles 17 is connected to the first rotating sleeve 15 by a belt.

[0110] Taking the embodiment combining all the features described in this application as an example, when the first rotating sleeve 15 rotates, a cross baffle 17 will rotate, thereby driving the first synchronous gear 1701 to rotate, and through meshing, driving another first synchronous gear 1701 to rotate, thereby driving another cross baffle 17 to rotate, and the two cross baffles 17 rotate in opposite directions.

[0111] When the intermittent rotating structure drives the feeding structure to move once, the cross baffle 17 rotates 90°, thereby pushing the plug onto the opening and closing plate 20 and isolating the next plug. This controls the spacing between the plugs and prevents the high-precision probe 301 from being interfered with when detecting the plug size due to excessively large or small spacing between adjacent plugs.

[0112] In another embodiment of the present invention, the release structure further includes a plurality of second synchronous gears 18 rotatably mounted on the conveying track 201; and the plurality of second synchronous gears 18 mesh with each other; one of the second synchronous gears 18 is connected to the second rotating sleeve 16 by a belt; a rotating rod 1801 is fixedly mounted on the second synchronous gear 18; a hinge rod 19 that is hinged to the opening and closing plate 20 is slidably fitted on the rotating rod 1801; and a limiting groove 202 that is slidably fitted on the conveying track 201 is provided to the opening and closing plate 20.

[0113] Taking the embodiment combining all the features described in this application as an example, when the second rotating sleeve 16 rotates in the forward direction, it will drive the second synchronous gear 18 to rotate synchronously, and drive another second synchronous gear 18 to rotate through meshing.

[0114] At this time, the rotating second synchronous gear 18 will drive the rotating rod 1801 to rotate, thereby driving the opening and closing plates 20 to move closer to each other through the hinge rod 19, so as to reduce the gap and facilitate the receiving of the plug pushed by the feeding structure; during this process, the hinge rod 19 slides outward in the rotating rod 1801.

[0115] When the second rotating sleeve 16 rotates in the opposite direction, it will drive the second synchronous gear 18 to rotate synchronously, and through meshing, it will drive another second synchronous gear 18 to rotate.

[0116] At this time, the rotating second synchronous gear 18 will drive the rotating rod 1801 to rotate, thereby driving the opening and closing plates 20 to move away from each other through the hinge rod 19, so as to increase the distance and release the plug on the glass turntable 4; during this process, the hinge rod 19 slides inward in the rotating rod 1801.

[0117] By coordinating the intermittent rotation structure with the feeding and releasing structures, the plug can be smoothly placed onto the glass turntable 4 when it is stationary. During the placement process, the relative sliding between the glass turntable 4 and the plug is small, which can effectively reduce the wear of the glass turntable 4 and avoid large errors in the detection results due to excessive wear of the glass turntable 4 under long-term operation; thus, it can effectively improve the detection accuracy.

[0118] In another embodiment of the present invention, the opening and closing plate 20 is provided with a slope.

[0119] Taking the embodiment combining all the features described in this application as an example, when in use, when the opening and closing plates 20 are close to each other, the plug pushed by the feeding structure will contact the plane at the top of the opening and closing plate 20 to receive the plug.

[0120] When the opening and closing plates 20 move away from each other, the plug will disengage from the plane and come into contact with the slope. Through the buffering effect of the slope, the kinetic energy released by the plug on the glass turntable 4 can be reduced, thereby reducing the wear of the glass turntable 4.

[0121] In another embodiment of the present invention, an inclined discharge baffle 103 is fixedly installed on the chassis 1; and the discharge baffle 103 cooperates with the waste outlet 102.

[0122] Taking the embodiment combining all the features described in this application as an example, when the unqualified plug stops at the jet pipe 501, the blowing module 5 does not operate, so when the glass turntable 4 rotates subsequently, it will continue to drive the plug to move.

[0123] When the plug moves to contact the discharge baffle 103, driven by the rotating glass turntable 4, the plug will move along the discharge baffle 103 to the waste outlet 102 until it falls into the waste outlet 102.

[0124] Through the screening action of the blowing module 5 and the discharge baffle 103, good products and defective products can be effectively separated.

[0125] In another embodiment of the present invention, the glass turntable 4 has high transparency.

[0126] Taking the embodiment combining all the features described in this application as an example, when in use, the detection light source can easily penetrate the glass turntable 4 with high transparency, so that the high-precision probe 301 can accurately detect the product size.
