Description

Technical Field

[0001] The present invention belongs to the technical field of particulate matter detection, and specifically relates to a nylon modified particle detection device. Background Art

[0002] Nylon modified particles are a type of engineering plastics. By adding various modifiers and additives, such as reinforcing agents and toughening agents, to nylon raw materials, their original physical and chemical properties can be changed. During the production process of nylon modified particles, visual inspection is usually required. Through inspection, problems such as impurities, breakage, and uneven color in the particles can be detected in a timely manner, thereby avoiding adverse effects on the final product caused by these problems.

[0003] In the prior art, the particles are placed on a detection table, and then a visual detection device is used to capture and process the image information of the particles in real time. Through image analysis technology, the morphology, color, size, and other characteristics of the particles can be accurately identified, and then it can be judged whether there are defects or non-compliance with quality standards. However, when the particles are placed on the detection table, the particles may be in a stacked state, and occlusion and overlap may occur between the stacked particles, causing some particles to be covered by other particles. This will result in the visual detection device being unable to capture the complete images of these occluded particles, and thus unable to accurately analyze and judge them.

[0015] The beneficial effects of the present invention are as follows: 1. A nylon modified particle detection device according to the present invention utilizes an adjustable leveling mechanism and a box mouth adaptable polymerization mechanism. First, the particles are leveled by the first push plate and the second push plate, and then the camera captures the particle images. This avoids the situation where, due to the particles being in a piled-up state, there is occlusion and overlap between the piled-up particles, causing some particles to be covered by other particles, resulting in the camera being unable to capture the complete images of these occluded particles. This is beneficial for improving the accuracy of subsequent analysis and judgment. Moreover, when the particles are placed on the detection table, the particles are in the surrounded area formed by multiple polymerization cloths. The approximate number of particles can be determined by weighing or visual assessment. Adjust the size of the rectangular surrounded area formed by the multiple polymerization cloths and the distance between the ends of the two second push plates until the ends of the two second push plates can fit the surfaces of the front and rear polymerization cloths. When the first push plate and the second push plate move horizontally, they can evenly level the particles within the surrounded area, avoiding leveling dead corners. And when the first push plate and the second push plate enter the surrounded area, they enter from the edge of the surrounded area and rise when moving to the other side of the surrounded area, and then push and level in the reverse direction. Thus, the particles can be leveled on the detection table and restricted within the surrounded area formed by multiple polymerization cloths, greatly reducing the dispersion range of the particles. Since the particle distribution is relatively regular, it avoids the situation where the camera needs to move frequently and adjust the focal length to capture the particle images at different positions, improving the subsequent analysis efficiency. And when the particle image capture work is completed, place the rectangular collection box for collecting particles on the bearing plate, and use two first clamping plates and two second clamping plates to center the collection box on the bearing plate. At this time, according to the specifications of the collection box, adjust the positions of the four adjustment columns again so that the adjustment columns are aligned with the four corners of the collection box. Then drive the detection table to move away from the bottom of the adjustment columns, and the particles within the range of the polymerization cloth will fall into the collection box. And since the four adjustment columns are aligned with the four corners of the collection box, the rectangle formed by the multiple polymerization cloths also matches the specifications of the collection box, and the particles will only fall within a fixed range, ensuring both the collection speed of the collection box for the particles and preventing the particles from falling outside the collection box, improving the efficiency of subsequent particle detection.

[0016] 2. A nylon modified particle detection device according to the present invention can, when the particles fall into the collection box, drive the first connecting rod and the second connecting rod to rotate by the fifth motor according to the length by which the polymerization cloth is stretched at this time, so that the eccentric column moves along the surface of the polymerization cloth. At the same time, drive the eccentric column to rotate by the fourth motor. When the eccentric column rotates, it will continuously squeeze the polymerization cloth, and thus, by means of squeezing, an external force can be applied to the polymerization cloth to promote the detachment of the particles adhered to the surface of the polymerization cloth, thereby avoiding the situation where, due to the particles frequently contacting the surface of the polymerization cloth, the particles adhere to the surface of the polymerization cloth, which in turn affects the normal collection of the particles and the situation where the particles on the surface of the polymerization cloth are mixed with the subsequent particles during the subsequent detection process.

[0028] At both ends of the chute of the left chute column 34, a fourth threaded rod 33 is rotatably arranged. The fourth threaded rod 33 is threadedly connected to one side of the bearing plate 13.

[0029] Specifically, in the prior art, the particles are placed on the detection table 10, and then the vision detection device 16 is used to capture and process the image information of the particles in real time. Through image analysis technology, the morphology, color, size and other characteristics of the particles can be accurately identified, and then it can be judged whether there are defects or non - compliance with quality standards. However, when the particles are placed on the detection table 10, the particles may be in a stacked state, and there will be occlusion and overlap between the stacked particles, so that some particles are covered by other particles, which will cause the vision detection device to be unable to capture the complete images of these occluded particles, thus unable to accurately analyze and judge them; Therefore, to solve the above problems, when this embodiment is in use, the particles to be visually inspected are placed on the inspection table 10. According to the height of the particle accumulation, the electric push rod 3 is used to drive the connecting plate 18 to lift and lower, so that appropriate gaps are generated between the bottoms of the first push plate 31 and the second push plate 32 and the upper surface of the inspection table 10. Then, the second motor 14 is used to drive the first threaded rod 5 to rotate, so that the slider 15 moves horizontally. Thus, the first push plate 31 and the second push plate 32 can be used to push the accumulated particles, so that the originally accumulated particles are leveled. Then, the light source on the visual inspection device 16 is used to illuminate the particles, and the camera is used to capture the images of the particles. This is an existing visual inspection technology and will not be elaborated too much here. The particle images captured by the camera will be transmitted to the display 19, and through image analysis technology, the characteristics of the particles such as their shape, color, and size are identified, so as to judge whether there are defects. Moreover, the particles are first leveled by the first push plate 31 and the second push plate 32, and then the camera captures the particle images, thus avoiding the situation where due to the particles being in a stacked state, there is occlusion and overlap between the stacked particles, causing some particles to be covered by other particles, resulting in the camera being unable to capture the complete images of these occluded particles, which is beneficial to improving the accuracy of subsequent analysis and judgment; Although the above methods can be used to flatten the particles to improve the accuracy of subsequent analysis and judgment, when the particles are pushed by the first pusher 31 and the second pusher 32, the particles will roll on the detection table 10 due to the external force, and the rolling orientation is difficult to control. This will cause the particles to be dispersed in various areas of the detection table 10 irregularly, so the camera needs to move and adjust the focal length frequently to capture the particle images at different positions, which affects the subsequent analysis efficiency. And usually, the detected particles need to be packed into boxes for subsequent processing. When the particles are too dispersed, it is not conducive to the unified collection of the particles. When using the method of pouring the particles into the collection box for collection, some particles may fall outside the collection box because the opening width of the collection box is smaller than the width of the detection table 10. When the particle feeding range is too small, the speed of the particles entering the collection box will be slow. When multiple batches of particles need to be detected in sequence, the slow feeding speed will affect the subsequent detection efficiency. Therefore, to avoid the above problems, when the particles are placed on the detection table 10, the particles are in the surrounded area formed by multiple polymerization cloths 12. According to the number of particles, the ninth motor 4 drives the second bidirectional threaded rod 35 to rotate, so that the two chute plates 6 slide in different directions at the same time, adjusting the distance between the left and right adjusting columns 11. Then, the third motor 20 drives the first bidirectional threaded rod 21 to rotate, adjusting the distance between the front and rear adjusting columns 11. During the movement of the adjusting column 11, the polymerization cloth 12 can be stretched, adjusting the size of the rectangular surrounded area formed by multiple polymerization cloths 12. And the tenth motor 29 drives the third threaded rods 30 on both sides to rotate, so that the second pushers 32 on both sides slide on the first pusher 31, adjusting the distance between the ends of the two second pushers 32 until the ends of the two second pushers 32 can fit the surfaces of the front and rear polymerization cloths 12. When the first pusher 31 and the second pusher 32 move horizontally, they can evenly flatten the particles within the surrounded area, avoiding flattening dead corners. And when the first pusher 31 and the second pusher 32 enter the surrounded area, they enter from the edge of the surrounded area and rise when moving to the other side of the surrounded area, and then push flat in the reverse direction. Thus, the particles can be flattened on the detection table 10 and restricted within the surrounded area composed of multiple polymerization cloths 12, greatly reducing the dispersion range of the particles. Since the particle distribution is relatively regular, the situation where the camera needs to move and adjust the focal length frequently to capture the particle images at different positions is avoided, improving the subsequent analysis efficiency; After the particle image capture work is completed, place the rectangular collection box used for collecting particles on the bearing plate 13. Then, drive the bidirectional threaded rod three 42 to rotate by the motor eight 41, so that the two clamping plates one 37 slide simultaneously and approach each other until they fit against the left and right sides of the collection box. Then, drive the threaded rods five 40 on both sides to rotate by the motor seven 39, so that the two clamping plates two 38 slide simultaneously until they fit against the front and back sides of the collection box, and the collection box can be centered and positioned on the bearing plate 13. At this time, according to the specifications of the collection box, adjust the positions of the four adjusting columns 11 again to align the adjusting columns 11 with the four corners of the collection box. Then, drive the threaded rod two 8 to rotate by the motor one 7, so that the detection table 10 moves on the threaded rod two 8 and the slide rod two 9, and the detection table 10 moves away from the bottom of the adjusting column 11. The particles within the range of the polymerization cloth 12 will fall into the collection box. Moreover, since the four adjusting columns 11 are all aligned with the four corners of the collection box, the rectangle formed by the multiple polymerization cloths 12 also matches the specifications of the collection box, and the particles will only fall within a fixed range, which not only ensures the collection speed of the collection box for the particles but also prevents the particles from falling outside the collection box, improving the efficiency of detecting the subsequent particles.

[0030] In this embodiment, as Figure 3 and Figure 6 shown, a cloth length adaptation type anti-adhesion mechanism for promoting the particles to fall into the collection box is further provided on the adjusting column 11; The cloth length adaptation type anti-adhesion mechanism includes a mounting block 22 fixedly connected to one side of the adjusting column 11. At both ends of one side of the mounting block 22, a connecting rod one 23 is rotatably provided. One end of the connecting rod one 23 is rotatably provided with a connecting rod two 24. One end of the connecting rod two 24 is rotatably provided with a displacement rod 25. One side of the upper end of the displacement rod 25 is rotatably provided with an eccentric column 26.

[0031] A motor five 28 is fixedly connected to one side of the mounting block 22. The output end of the motor five 28 is fixedly connected to one end of the connecting rod one 23. A motor four 27 is fixedly connected to one side of the upper end of the displacement rod 25. The output end of the motor four 27 is fixedly connected to one end of the eccentric column 26.

[0032] Specifically, in the above embodiments, although the range of the particles can be restricted by using the polymerization cloth 12, however, since some particles may have a certain adhesiveness, when the particles frequently come into contact with the surface of the polymerization cloth 12, it is easy for the particles to adhere to the surface of the polymerization cloth 12, thereby affecting the normal collection of the particles. Even in the subsequent detection process, the particles on the surface of the polymerization cloth 12 may be mixed with the subsequent particles to be detected. Therefore, to avoid this situation, when the particles fall into the collection box, according to the length by which the polymerization cloth 12 is stretched at this time, the fifth motor 28 drives the first connecting rod 23 and the second connecting rod 24 to rotate, so that the eccentric column 26 moves along the surface of the polymerization cloth 12. At the same time, the fourth motor 27 drives the eccentric column 26 to rotate. When the eccentric column 26 rotates, it will continuously squeeze the polymerization cloth 12. That is, an external force can be applied to the polymerization cloth 12 by squeezing to promote the detachment of the adhered particles on the surface of the polymerization cloth 12, thereby avoiding the situation where the particles adhere to the surface of the polymerization cloth 12 due to the frequent contact between the particles and the surface of the polymerization cloth 12, which in turn affects the normal collection of the particles, and the situation where the particles on the surface of the polymerization cloth 12 are mixed with the subsequent particles in the subsequent detection process.

[0033] Working principle: Place the particles to be visually inspected on the inspection table 10. According to the height of the particle accumulation, use the electric push rod 3 to drive the connecting plate 18 to lift and lower, so that appropriate gaps are generated between the bottoms of the first pushing plate 31 and the second pushing plate 32 and the upper surface of the inspection table 10. Then use the second motor 14 to drive the first threaded rod 5 to rotate, so that the slider 15 moves horizontally, and then the first pushing plate 31 and the second pushing plate 32 can be used to push the accumulated particles, so that the originally accumulated particles are flattened. Then use the light source on the visual inspection device 16 to illuminate the particles, and capture the images of the particles through the camera. This is an existing visual inspection technology and will not be elaborated too much; the particle images captured by the camera will be transmitted to the display 19, and through image analysis technology, the features such as the shape, color, and size of the particles are identified, so as to judge whether there are defects. Moreover, the particles are first flattened by the first pushing plate 31 and the second pushing plate 32, and then the camera captures the particle images, thus avoiding the situation that due to the particles being in a stacked state, occlusion and overlap occur between the stacked particles, so that some particles are covered by other particles, resulting in the camera being unable to capture the complete images of these occluded particles, which is beneficial to improving the accuracy of subsequent analysis and judgment;Although the above methods can be used to flatten the particles to improve the accuracy of subsequent analysis and judgment, when the particles are pushed by the first pusher 31 and the second pusher 32, the particles will roll on the detection table 10 due to external forces, and the rolling orientation is difficult to control, which will cause the particles to be dispersed in various regions of the detection table 10 in a relatively irregular manner. Then, the camera needs to move and adjust the focal length frequently to capture the particle images at different positions, affecting the subsequent analysis efficiency. Moreover, usually, the detected particles need to be packed into boxes for subsequent processing. When the particles are too dispersed, it is not conducive to the unified collection of the particles. When the method of pouring the particles into the collection box for collection is adopted, some particles may fall outside the collection box because the opening width of the collection box is smaller than the width of the detection table 10. When the particle feeding range is too reduced, the speed of the particles entering the collection box will be slower. When multiple batches of particles need to be detected in sequence, the slow feeding speed will affect the subsequent detection efficiency. Therefore, to avoid the above problems, when the particles are placed on the detection table 10, the particles are in the surrounded area formed by multiple aggregation cloths 12. According to the number of particles, the motor nine 4 drives the bidirectional threaded rod two 35 to rotate, so that the two chute plates 6 slide in different directions at the same time, adjusting the distance between the left and right adjusting columns 11. Then, the motor three 20 drives the bidirectional threaded rod one 21 to rotate, adjusting the distance between the front and rear adjusting columns 11. During the movement of the adjusting column 11, the aggregation cloth 12 can be stretched, adjusting the size of the rectangular surrounded area formed by multiple aggregation cloths 12. And the motor ten 29 drives the threaded rods three 30 on both sides to rotate, so that the second pushers 32 on both sides slide on the first pusher 31, adjusting the distance between the ends of the two second pushers 32 until the ends of the two second pushers 32 can fit the surfaces of the front and rear aggregation cloths 12. When the first pusher 31 and the second pusher 32 move horizontally, they can evenly flatten the particles within the surrounded area, avoiding flattening dead corners. Thus, the particles can be flattened on the detection table 10 and restricted within the surrounded area composed of multiple aggregation cloths 12, greatly reducing the dispersion range of the particles. Since the particle distribution is relatively regular, the situation where the camera needs to move and adjust the focal length frequently to capture the particle images at different positions is avoided, improving the subsequent analysis efficiency;After the particle image capture work is completed, place the rectangular collection box used for collecting particles on the bearing plate 13, and then use the motor eight 41 to drive the bidirectional threaded rod three 42 to rotate, so that the two clamping plates one 37 slide simultaneously and approach each other until they fit against the left and right sides of the collection box. Then use the motor seven 39 to drive the threaded rods five 40 on both sides to rotate, so that the two clamping plates two 38 slide simultaneously until they fit against the front and back sides of the collection box, and the collection box can be centered and positioned on the bearing plate 13. At this time, according to the specifications of the collection box, the positions of the four adjusting columns 11 can be adjusted again to align the adjusting columns 11 with the four corners of the collection box. Then use the motor one 7 to drive the threaded rod two 8 to rotate, so that the detection table 10 moves on the threaded rod two 8 and the slide rod two 9, and the detection table 10 moves away from the bottom of the adjusting column 11. The particles within the range of the polymerization cloth 12 will fall into the collection box. Moreover, since the four adjusting columns 11 are all aligned with the four corners of the collection box, the rectangle formed by the multiple polymerization cloths 12 also matches the specifications of the collection box, and the particles will only fall within a fixed range, which not only ensures the collection speed of the collection box for the particles but also prevents the particles from falling outside the collection box, improving the efficiency of subsequent particle detection. When the particles fall into the collection box, according to the length by which the polymerization cloth 12 is stretched at this time, use the motor five 28 to drive the connecting rod one 23 and the connecting rod two 24 to rotate, so that the eccentric column 26 moves along the surface of the polymerization cloth 12. At the same time, use the motor four 27 to drive the eccentric column 26 to rotate. When the eccentric column 26 rotates, it will continuously squeeze the polymerization cloth 12, and external force can be applied to the polymerization cloth 12 by squeezing to promote the shedding of the particles adhered to the surface of the polymerization cloth 12, thus avoiding the situation where the particles adhere to the surface of the polymerization cloth 12 due to frequent contact with the surface of the polymerization cloth 12, which in turn affects the normal collection of the particles and the mixing of the particles on the surface of the polymerization cloth 12 with the subsequent particles during the subsequent detection process.;
