Description

Technical Field

[0001] This utility model relates to the field of oil seal production and testing technology, and in particular to an oil seal appearance inspection and sorting device. Background Technology

[0002] Currently, after production, oil seals undergo visual inspection and sorting to select qualified products. A camera quickly captures images of the oil seals on the production line, transmitting the image data to an image processing system. The image processing system preprocesses each image, performs dimensional measurements, and compares it with standard template images and set parameters to determine product qualification. If the oil seal is found to have visual defects such as edge notches, burrs, dirt, insufficient adhesive, damage, or breakage, or if its inner / outer diameter, side height, or other dimensions do not meet standards, it is deemed a defective product. A scrap alarm and rejection control signal are output, and the mechanical system removes the defective product. However, during the testing process, the lens of the camera component is prone to dust, oil and other impurities, which leads to a decrease in testing accuracy. Traditional cleaning methods require manual wiping or additional electric cleaning mechanisms. Manual cleaning is inefficient and easily interrupts the testing process, making it difficult to adapt to the scenario of continuous conveying and testing of oil seals. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an oil seal appearance inspection and sorting device.

[0004] This utility model is achieved using the following technical solution: an oil seal appearance inspection and sorting device, comprising a sorting machine body, an internal camera assembly for appearance inspection of the oil seals, a robotic arm assembly for sorting the oil seals on one side of the camera assembly, a conveying assembly for conveying the oil seals inside the sorting machine body, the conveying assembly comprising a mounting frame and a conveyor belt mounted on the mounting frame, symmetrically arranged on both sides of the camera assembly with air blowing assemblies capable of cleaning the lens of the camera assembly, a plurality of driving assemblies capable of driving the air blowing assemblies for air blowing cleaning on the conveyor belt, the air blowing assembly comprising an elastic airbag fixedly mounted on one side of the mounting frame, the top of the elastic airbag being fixedly connected to an air blowing pipe, and a fixing block fixedly mounted on the air blowing pipe and fixedly installed on the mounting frame.

[0005] Through the above technical solution, when the conveyor belt drives the drive component to move, it can trigger the blower component to blow air onto the lens of the camera component, realizing the linkage of "conveyor-cleaner"; the fixing block can fix the position of the blower tube, ensuring that the air outlet is accurately aligned with the lens and avoiding cleaning deviation.

[0006] As a further improvement to the above solution, the air outlet of the blower extends to the bottom side of the lens of the camera assembly.

[0007] With the above technical solution, the air outlet of the blower tube is close to the bottom of the lens, which can directly blow away impurities on the lens surface and avoid the accumulation of impurities affecting the clarity of the test image.

[0008] As a further improvement to the above solution, push plates are fixedly installed on both sides of the inner cavity of the elastic airbag, and a first spring is fixedly installed between the two push plates.

[0009] With the above technical solution, after the elastic airbag is squeezed, the first spring can push the elastic airbag to reset through the push plate, so that it can re-inhale air and prepare for the next blowing, thus realizing the cycle of cleaning action.

[0010] As a further improvement to the above solution, the drive assembly includes a positioning plate fixedly installed on the conveyor belt for positioning the oil seal. A first push rod is fixedly installed on both sides of the positioning plate. A sliding hole is opened at the far end of the two first push rods. A second push rod is slidably arranged inside the two sliding holes. A ball is rotatably installed at one end of the two second push rods. A limiting block fixedly installed on the first push rod is fixedly sleeved on it and fixedly installed on the conveyor belt.

[0011] Through the above technical solutions, the positioning plate can limit the position of the oil seal on the conveyor belt and prevent the oil seal from shifting during detection; the ball bearings can convert the sliding friction between the second push rod and the limiting plate into rolling friction, reducing component wear; and the limiting block can fix the connection between the first push rod and the conveyor belt.

[0012] As a further improvement to the above solution, a second spring is provided inside each of the two sliding holes, and the two ends of the two second springs are respectively fixedly installed to the second push rod and the inner wall of the sliding hole.

[0013] With the above technical solution, when the ball is released from the pressure of the limiting plate, the second spring can push the second push rod to extend out of the sliding hole, so that the ball hits the elastic air bag, thereby achieving air blowing cleaning. The elastic force of the second spring is greater than the elastic force of the first spring combined with the elastic air bag.

[0014] As a further improvement to the above solution, a limiting plate is fixedly installed on one side of each of the two elastic airbags, and one side of the two limiting plates is inclined to squeeze and push the ball bearings.

[0015] Through the above technical solution, the inclined limiting plate can guide the ball to gradually squeeze the second spring. At the moment the second spring releases its elastic force, the ball hits the elastic airbag, thereby achieving air blowing cleaning of the lens.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a conveyor belt to drive the drive assembly to move, triggering the blower assembly to automatically clean the camera lens without manual intervention or additional power source, thus reducing equipment cost and operation difficulty; the elastic airbag, in conjunction with the first spring, can achieve automatic reset, and the limiting plate and drive assembly, in conjunction with the second spring, automatically squeeze the elastic airbag to achieve compression of the elastic airbag.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Please combine Figures 1-6 This embodiment of an oil seal appearance inspection and sorting device includes a sorting machine body 1. Inside the sorting machine body 1 is a camera assembly 2 for appearance inspection of the oil seals. On one side of the camera assembly 2 is a robotic arm assembly 3 for sorting the oil seals. Inside the sorting machine body 1 is a conveying assembly for conveying the oil seals. The conveying assembly includes a mounting frame 401 and a conveyor belt 402 mounted on the mounting frame 401. On both sides of the camera assembly 2 are symmetrically arranged air blowing assemblies capable of cleaning the lens of the camera assembly 2. The conveyor belt 402 is provided with multiple drive assemblies capable of driving the air blowing assemblies for cleaning.

[0021] The blower assembly includes an elastic airbag 501 fixedly installed on one side of the mounting bracket 401. The top of the elastic airbag 501 is fixedly connected to a blower pipe 502. A fixing block 503 fixedly installed on the blower pipe 502 and fixedly mounted on the mounting bracket 401 is fixedly sleeved on the blower pipe 502. The air outlet end of the blower pipe 502 extends to the bottom side of the lens of the camera assembly 2.

[0022] When the conveyor belt 402 drives the drive component to move, it can trigger the blower component to blow air onto the lens of the camera component 2, realizing the "conveying-cleaning" linkage; the fixing block 503 can fix the position of the blower pipe 502 to ensure that the air outlet is accurately aligned with the lens and avoid cleaning deviation.

[0023] Both sides of the inner cavity of the elastic airbag 501 are fixedly installed with push plates 7, and a first spring 8 is fixedly installed between the two push plates 7.

[0024] After the elastic airbag 501 is squeezed, the first spring 8 can push the elastic airbag 501 to reset through the push plate 7, so that it can re-inhale air and prepare for the next blowing, thus realizing the cycle of cleaning action.

[0025] The drive assembly includes a positioning plate 601 fixedly mounted on the conveyor belt 402 for positioning the oil seal. First push rods 602 are fixedly mounted on both sides of the positioning plate 601. Sliding holes are opened at the ends of the two first push rods 602 that are far apart. Second push rods 603 are slidably arranged inside the two sliding holes. Ball bearings 604 are rotatably mounted on one end of the two second push rods 603. A limiting block fixedly mounted on the first push rod 602 and fixedly installed on the conveyor belt 402 is fixedly sleeved on it.

[0026] The positioning plate 601 can limit the position of the oil seal on the conveyor belt 402 to prevent the oil seal from shifting during testing; the ball 604 can convert the sliding friction between the second push rod 603 and the limiting plate 10 into rolling friction, reducing component wear; the limiting block can fix the connection between the first push rod 602 and the conveyor belt 402.

[0027] The interior of each of the two sliding holes is provided with a second spring 9, and the two ends of the two second springs 9 are fixedly installed to the second push rod 603 and the inner wall of the sliding hole, respectively.

[0028] When the ball 604 is released from the pressure of the limiting plate 10, the second spring 9 can push the second push rod 603 to extend out of the sliding hole, so that the ball 604 hits the elastic air bag 501, thereby achieving air blowing cleaning. The elastic force of the second spring 9 is greater than the elastic force of the first spring 8 combined with the elastic air bag 501.

[0029] A limiting plate 10 is fixedly installed on one side of each pair of elastic airbags 501. One side of each limiting plate 10 is inclined to compress and push the ball bearings 604.

[0030] The inclined limiting plate 10 can guide the ball 604 to gradually squeeze the second spring 9. At the moment the second spring 9 releases its elasticity, the ball 604 hits the elastic airbag 501, thereby achieving air blowing cleaning of the lens.

[0031] The implementation principle of the appearance inspection and sorting device for oil seals in this embodiment is as follows: the oil seal to be inspected is placed on the conveyor belt 402, so that one side of the oil seal is in contact with the positioning plate 601. The positioning plate 601 positions the oil seal to prevent the oil seal from shifting during the conveying process. At this time, the drive component is in the initial position with the conveyor belt 402. Under the restriction of the second spring 9, the second push rod 603 is mostly located in the sliding hole of the first push rod 602, and the ball 604 does not contact the limiting plate 10. The elastic airbag 501 is in a naturally inflated state, storing air inside, and the first spring 8 is in a naturally extended state.

[0032] The conveyor belt 402 is started, and it moves the positioning plate 601 and oil seal towards the camera assembly 2 along the track of the mounting frame 401. As the positioning plate 601 moves, it simultaneously moves the first push rods 602 on both sides. The first push rods 602 drive the ball bearings 604 to move synchronously through the second push rod 603 in the sliding hole. When the ball bearings 604 move to the inclined surface of the limiting plate 10, the inclined structure of the limiting plate 10 exerts a squeezing force on the ball bearings 604 towards the inside of the sliding hole. Under the squeezing force, the ball bearings 604 push the second push rod 603 to slide inward along the sliding hole of the first push rod 602. During this process, the second spring 9 is compressed. After the ball bearings 604 separate from the limiting plate 10, the second... When spring 9 loses the pressure from the ball bearing 604 pushing the second push rod 603, it will regain its elasticity. When it regains its elasticity, it will push the second push rod 603 and the ball bearing 604, causing the pushed ball bearing 604 to directly compress the elastic airbag 501. The elastic airbag 501 is compressed. The elastic force of the second spring 9 is greater than the elastic force of the first spring 8 combined with the elastic force of the elastic airbag 501. After the elastic airbag 501 is compressed, the internal air is quickly discharged through the top blower pipe 502. The air outlet of the blower pipe 502 is aimed at the bottom of the lens of the camera assembly 2. The discharged air blows away dust and other impurities on the lens surface, thus cleaning the lens. During this process, the fixing block 503 fixes the position of the blower pipe 502 to ensure that the air outlet direction is stable and does not deviate.

[0033] As the conveyor belt 402 continues to move, the positioning plate 601 drives the first push rod 602, the second push rod 603, and the ball bearing 604 to gradually move away from the elastic airbag 501. When the ball bearing 604 completely disengages from the elastic airbag 501, the restoring force of the second spring 9 pushes the second push rod 603 back to its initial position within the sliding hole of the first push rod 602. At the same time, after the elastic airbag 501 loses its compression, the push plates 7 on both sides of its inner cavity move to both sides under the elastic force of the first spring 8, causing the elastic airbag 501 to re-inflate and draw in air from the outside to store air for the next cleaning operation. The conveyor belt 402 continues to drive the oil seal to move.

[0034] Each inspection involves camera component 2 taking a picture of the oil seal's appearance after cleaning the lens to determine if the oil seal is qualified. If qualified, robotic arm component 3 picks up the oil seal and moves it to the qualified area; if unqualified, it is picked up and moved to the unqualified area, completing one inspection and sorting process.

[0035] As the oil seal is conveyed along with the conveyor belt 402, each drive component will repeat the above "movement-squeezing-blowing-resetting" process to achieve continuous automatic cleaning of the camera lens and ensure the accuracy of each inspection.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
