Description

Technical Field

[0001] This invention belongs to the field of sorting equipment technology, specifically an automatic detection and sorting device for magnetic materials. Background Technology

[0002] A magnetic ring is a ring-shaped magnetic conductor, mainly made of ferrite material. It is a commonly used anti-interference component in electronic circuits, which can effectively suppress high-frequency noise. However, during the production process, magnetic rings may have defects such as surface cracks and burrs. These defects can accelerate material aging or cause local magnetic field distortion, thereby shortening the service life. Therefore, it is necessary to inspect the magnetic rings.

[0003] In existing technologies, magnetic ring sorting often uses rotary sorting machines. The main process involves a conveyor belt feeding the magnetic rings to be inspected one by one into slots on the side surface of the rotary table. Since each slot can only hold one magnetic ring, only one magnetic ring is transferred away as the rotary table rotates, entering the next inspection mechanism. After passing the inspection, the qualified magnetic ring is removed from the slot by the unloading component, while the unqualified magnetic ring continues to rotate with the rotary table and is removed by the next unloading component, thus completing the sorting of magnetic rings.

[0004] In the aforementioned technologies, the rotary sorting machine can efficiently complete the task of sorting out multiple workpieces of different qualities. However, when only two types of workpieces need to be sorted out, namely qualified and unqualified workpieces, the multiple sorting stations of the rotary sorting machine will be wasted, and the sorting efficiency will not be improved.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 6As shown in the embodiment of the present invention, an automatic magnetic material detection and sorting device includes a base 1; a tray 2 is fixedly connected to the top surface of the base 1; a chain 3 is installed on the top surface of the tray 2, and the chain 3 is driven by a servo motor through gears; a pair of symmetrically arranged support plates 4 are fixedly connected to the top surface of the tray 2; both support plates 4 are arc-shaped and located inside the two chains 3 respectively; a plurality of evenly arranged transfer seats 5 are installed on the surface of the chain 3; a receiving groove 6 is opened on the surface of the transfer seat 5; a through groove 7 is opened at the bottom of the receiving groove 6; a baffle 8 is fixedly connected to the side surface of the tray 2, and the baffle 8 is arranged in a ring; a pair of notches 1 9, a pair of notches 2 10 and a pair of notches 3 11 are opened on the surface of the baffle 8, and the notches 1 9 and 2 10 are arranged in pairs. Both notch 10 and notch 3 11 are symmetrically arranged; magnetic sensors 12 are slidably connected to the surface of the tray 2 at the corresponding positions of notch 2 10, and the magnetic sensors 12 are driven by electric push rods; cylinders 13 are fixedly connected to the top surface of the baffle 8 at the corresponding positions of notch 2 10 and notch 3 11; the telescopic end of cylinder 13 is fixedly connected to a push plate 14; cylinder 2 141 is fixedly connected to the top surface of the tray 2 near the middle position; the telescopic end of cylinder 2 141 is fixedly connected to a push plate 142; the magnetic sensors 12 are connected to cylinder 13 through a PLC control circuit; a conveying assembly is provided at the position of notch 1 9; the conveying assembly includes a pair of conveyor belts 15, which are connected to an external centrifugal disc feeder for conveying the magnetic rings to be tested one by one to notch 1 9;In order to improve the detection efficiency of magnetic rings during operation, the present invention embodiment is used. First, the conveyor belt 15 sends the magnetic ring to be tested to the two notches 9 on both sides and enters the receiving groove 6 on the surface of the transfer seat 5 at notch 9. The top of the magnetic ring will be higher than the top surface of the transfer seat 5. During this process, the rotating chain 3 will move the transfer seat 5 and the magnetic ring to be tested together to notch 10. During the rotation, the baffle 8 will block the magnetic ring to be tested to prevent it from being thrown off the top surface of the tray 2. At this time, the electric push rod will push the magnetic sensor 12 to rise and pass through the through groove 7 to enter the inside of the magnetic ring to be tested, thereby completing the detection of the magnetic ring to be tested. If the detection result meets the requirements, the paddle 14 will be driven by the cylinder 13 to push the qualified magnetic ring out from notch 10. The unqualified magnetic ring will continue to move with the transfer seat 5 to notch 11 and be pushed out by the paddle 14 at notch 11. 4. The magnetic ring is pulled out from notch 3 11. When multi-quality grading and sorting of magnetic rings is required, the user can add new detection devices at each notch 2 10 and notch 3 11. Then, after the chain 3 on one side drives the magnetic ring past the notch 2 10 and notch 3 11 near that side, if the magnetic ring is still not picked up, the chain 3 will transfer the magnetic ring to the cylinder 2 141 through the transfer seat 5. At this time, the cylinder 2 141 will drive the push plate 142 to move, pushing the magnetic ring onto the transfer seat 5 on the surface of the chain 3 on the other side. The chain 3 that has obtained the magnetic ring can then drive the magnetic ring to traverse the notch 2 10 and notch 3 11 near its side, thereby realizing multi-quality grading and sorting of magnetic rings. When the user only needs to sort out qualified and unqualified, the two side chains 3 rotate in opposite directions. Thus, the user can not only complete multi-quality grading and sorting of magnetic rings, but also simultaneously perform quality detection on two groups of magnetic rings through the two chains 3, thereby improving the detection efficiency of magnetic rings.

[0033] like Figures 1 to 3 As shown, a connecting plate 16 is fixedly connected to the side of the lever 14 near the cylinder 13; a straight plate 17 is fixedly connected to the end of the connecting plate 16 away from the lever 14, and the straight plate 17 is perpendicular to the connecting plate 16; a guide plate 18 is fixedly connected to the surface of the baffle 8 at the positions of notch 2 10 and notch 3 11, and the guide plate 18 is inclined; during operation, when the transfer seat 5 moves the magnetic ring to the position of notch 2 10 or notch 3 11, the lever 14 and the straight plate 17 at the extension end of the cylinder 13 will cause the magnetic ring to... The ring is positioned between the two, thus preventing the magnetic ring from coming out of the receiving groove 6 due to inertia. When it is necessary to remove the magnetic ring from the second notch 10 or the third notch 11, the cylinder 13 drives the connecting plate 16 and the straight plate 17 to move together via the lever 14 until the magnetic ring is carried by the two to the guide plate 18. Thus, the magnetic ring can slide away from the base 1 and the tray 2 along the guide plate 18. Thus, the user only needs to place the receiving frame on the side of the guide plate 18 away from the baffle 8 to collect it, which makes the collection convenient for the user.

[0034] like Figure 1 and Figure 6 As shown, a limiting plate 19 is fixedly connected to the top surface of the support plate 4; the limiting plate 19 is L-shaped and includes a vertical part and a horizontal part; a plurality of evenly arranged rollers 20 are rotatably connected to the vertical part of the limiting plate 19 and the surface of the support plate 4; a support ring 21 is fixedly connected to the top surface of the tray 2, and the bottom surface of the transfer seat 5 is flush with the top surface of the support ring 21; the magnetic sensor 12 is slidably connected to the support ring 21; during operation, when the chain 3 moves under the drive of the gear, the support... Plate 4 and limiting plate 19 restrict the chain 3 from approaching the baffle 8, allowing the transfer seat 5 on the surface of the chain 3 to fit against the baffle 8. This ensures that the magnetic ring in the receiving groove 6 can be smoothly dislodged from notch 10 or notch 11. At the same time, the support wheels on the surface of limiting plate 19 and support plate 4 reduce the friction between the chain 3 and limiting plate 19 and support plate 4 when the chain 3 moves. The support ring 21 at the bottom of the tray 2 also provides support for the transfer seat, preventing the chain 3 from tilting due to force on one side.

[0035] like Figures 4 to 5 As shown, the top and bottom surfaces of the transfer seat 5 are provided with clamping plates 22, and the clamping plates 22 are made of elastic material; the clamping plates 22 are fixedly connected to the surface of the chain 3; the two clamping plates 22 are fixedly connected to the side of each other; the top and bottom surfaces of the transfer seat 5 are provided with grooves 24 at the corresponding positions of the compression blocks 23, and the grooves 24 are adapted to the compression blocks 23; the pair of clamping plates 22 and compression blocks 23 are connected to the transfer seat 5 between them by bolts; during operation, when the user needs to test magnetic rings of different diameters, the user can tighten the bolts to disengage the clamping plates 22 from the transfer seat 5. At this time, the user can replace the transfer seat 5 so that the receiving groove 6 on its surface is adapted to the magnetic ring to be tested, and then insert the compression block 23 on the surface of the clamping plate 22 into the groove 24 on the surface of the transfer seat 5, thereby locking the transfer seat 5, and clamping the transfer seat 5 by the elasticity of the clamping plates 22, thus making it convenient for the user to tighten the bolts and replace the transfer seat 5.

[0036] like Figure 1 , Figure 7 , Figure 8 and Figure 9As shown, the conveying assembly also includes a pair of roller conveyors 25; the two roller conveyors 25 are arranged in an arc shape and are respectively connected to two notches 9; the conveyor belt 15 is located between the two roller conveyors 25; a transfer platform 26 is provided between the conveyor belt 15 and the two roller conveyors 25, and the transfer platform 26 is fixedly connected to the base 1; a distribution plate 27 is rotatably connected to the top surface of the transfer platform 26, and the distribution plate 27 is driven by a drive assembly; the baffle 8 is positioned at the corresponding position of the distribution plate 27. A clearance groove 28 is provided at the distribution plate 27; a pair of transfer grooves 29 are provided on the surface of the distribution plate 27, and the lines connecting the two transfer grooves 29 to the center of the distribution plate 27 are perpendicular to each other; cylinders 30 are fixedly connected to the ends of the two roller conveyors 25 near the notch 9; during operation, when it is necessary to transport the magnetic ring to be tested to the two notches 9, the conveyor belt 15 will first send the magnetic ring to be tested to the distribution plate 27 at the transfer table 26, and it will be inserted into the transfer groove 29 on the surface of the distribution plate 27, and then the distribution plate 27 will rotate. The magnetic ring to be tested in one transfer trough 29 is moved to one side onto the roller conveyor 25, while the other transfer trough 29 rotates to the conveyor belt 15 to receive the next magnetic ring to be tested. Then, the distribution disc 27 resets, and the transfer trough 29 that just received the magnetic ring to be tested will transfer the magnetic ring to be tested to the other roller conveyor 25 as the distribution disc 27 rotates. This completes the process of transferring the magnetic rings to be tested from the conveyor belt 15 to the roller conveyors 25 on both sides. Meanwhile, when the roller conveyor is full of magnetic rings to be tested, the distribution plate 27 can still rotate normally, avoiding jamming due to too many magnetic rings to be tested. When the magnetic rings to be tested are transported to the gap 9, the cylinder 30 starts and pushes the magnetic rings to be tested into the receiving groove 6 on the surface of the transfer seat 5. At the same time, the telescopic end of the cylinder 30 will also block the end of the roller conveyor 25 near the gap 9, thereby preventing multiple magnetic rings to be tested from entering the gap 9 and causing the gap 9 to be blocked.

[0037] like Figures 7 to 8 As shown, a pair of symmetrically arranged support platforms 31 are fixedly connected to the top surface of the transfer platform 26; the support platforms 31 are arranged in a fan shape and are located between the conveyor belt 15 and the roller conveyor 25; a side plate 32 is fixedly connected to the side surface of the support platform 31; the side plate 32 is arranged in an arc shape and is adapted to the distribution plate 27; during operation, when the distribution plate 27 rotates, the side plate 32 on the top surface of the support platform 31 will restrict the magnetic ring in the transfer groove 29, preventing it from being thrown away from the transfer groove 29 due to centrifugal force.

[0038] like Figures 7 to 9As shown, the driving assembly includes a driving rod 36; the driving rod 36 has a rectangular cross-section and is rotatably connected to the top surface of the rotating platform, and is driven by a servo motor; a slot 37 is provided at the center of the surface of the distribution disk 27, and the slot 37 is adapted to the driving rod 36; a support plate 38 is fixedly connected to the bottom surface of the distribution disk 27 on the surface of the driving rod 36; a threaded post 39 is fixedly connected to the top surface of the driving rod 36; a pressure plate 40 is sleeved on the threaded post 39; a nut 41 is threadedly connected to the top of the pressure plate 40 on the surface of the threaded post 39; during operation, when it is necessary to drive the distribution disk 27 to rotate, the servo motor will drive the driving rod 36 to rotate, and the rotating driving rod 36 will drive the distribution disk 27 to rotate through the slot 37 on the surface of the distribution disk 27, and the distribution disk 27 rotates during the process. The pressure plate 40 and the support plate 38 will clamp the distribution plate 27 under the pressure of the nut 41, thus preventing the distribution plate 27 from coming off the drive rod 36. When the user replaces the transfer seat 5 due to the change in the diameter of the magnetic ring to be tested, the user also needs to replace the distribution plate 27. At this time, the user needs to unscrew the nut 41 on the surface of the stud to remove it from the stud surface. Then the user removes the pressure plate 40 and the distribution plate 27 and replaces them. Since the cross-section of the drive rod 36 is rectangular, when the user inserts the slot 37 on the surface of the newly replaced distribution plate 27 into the drive rod 36, the position of the distribution plate 27 can be easily adjusted, so that one of the two transfer grooves 29 on the surface of the distribution plate 27 is aligned with the conveyor belt 15 and the other is aligned with the roller conveyor 25, which facilitates the user's installation.

[0039] like Figures 7 to 8 As shown, the top of the side plate 32 is provided with a rotating groove 33; a rotating plate 34 is rotatably connected in the rotating groove 33; the rotating plate 34 is made of magnet, and the side plate 32 is made of magnetized metal; the top surface of the distribution disk 27 is provided with a slot 35 between the two transfer grooves 29, and the slot 35 is aligned with the rotating plate 34; during operation, when the user needs to tighten the nut 41, the user can rotate the rotating plate 34 in the rotating groove 33 aligned with the slot 35, so that the rotating plate 34 is locked in the slot 35, thereby restricting the rotation of the distribution disk 27 and the drive rod 36, thus making it convenient for the user to unscrew the nut 41. After replacement, the user needs to rotate the rotating plate 34 back into the rotating groove 33. At this time, since the rotating plate 34 is made of magnet, the rotating plate 34 will be attracted in the rotating groove 33, thereby avoiding interference with the rotation of the distribution disk 27.

[0040] like Figure 1 and Figure 7As shown, an arc-shaped plate 42 is provided on the side of the roller conveyor 25 away from the baffle 8, and the baffle 8 is located at the top of the roller conveyor 25; a connecting seat 43 is fixedly connected to the side of the roller conveyor 25 away from the baffle 8; a threaded rod 44 is rotatably connected to the side of the arc-shaped plate 42 away from the baffle 8, and the threaded rod 44 is threadedly connected to the connecting seat 43; during operation, when the user needs to test magnetic rings of different diameters, the user needs to screw the threaded rod 44 at the connecting seat 43 according to the diameter of the magnetic ring, thereby driving the arc-shaped plate 42 closer to the baffle 8, so that the gap between the arc-shaped plate 42 and the baffle 8 only allows one magnetic ring to pass through, thereby preventing multiple magnetic rings from entering the gap 9 and causing the transfer seat 5 at the gap 9 to be stuck.

[0041] like Figures 8 to 9 As shown, air outlets 45 are provided at the bottom of the two transfer troughs 29; a pair of guide tubes 46 are fixedly connected to the top surface of the distribution plate 27, and the guide tubes 46 are connected to the air outlets 45; the guide tubes 46 are connected to an external air pump assembly; during operation, when the transfer trough 29 rotates with the magnetic ring to the roller conveyor 25, the guide tubes 46 will introduce gas into the air outlets 45 and blow it towards the magnetic ring in the transfer trough 29, making it easier for the magnetic ring to detach from the transfer trough 29 and preventing the magnetic ring from getting stuck in the transfer trough 29.

[0042] In order to improve the detection efficiency of magnetic rings during operation, this embodiment of the invention is used. First, the conveyor belt 15 sends the magnetic ring to be tested to the two notches 9 on both sides and enters the receiving groove 6 on the surface of the transfer seat 5 at notch 9. During this process, the rotating chain 3 will move the transfer seat 5 and the magnetic ring to be tested together to notch 10. During the rotation, the baffle 8 will block the magnetic ring to be tested to prevent it from being thrown off the top surface of the tray 2. At this time, the electric push rod will push the magnetic sensor 12 to rise and pass through the through groove 7 to enter the inside of the magnetic ring to be tested, thereby completing the detection of the magnetic ring to be tested. If the detection result meets the requirements, the paddle 14 will be driven by the cylinder 13 to push the qualified magnetic ring out from notch 10, while the unqualified magnetic ring will continue to move with the transfer seat 5 to notch 11 and be pushed out from notch 11 by the paddle 14 at notch 11. When multiple quality grades of magnetic rings need to be sorted, the user can add new detection devices at each of the two notches 10 and three notches 11. Then, after the chain 3 on one side drives the magnetic ring past the notches 10 and three notches 11 on that side, if the magnetic ring is still not picked up, the chain 3 will transfer the magnetic ring to the cylinder 141 through the transfer seat 5. At this time, the cylinder 141 will drive the push plate 142 to move, pushing the magnetic ring to the transfer seat 5 on the surface of the chain 3 on the other side. The chain 3 that has obtained the magnetic ring can then drive the magnetic ring to traverse the notches 10 and three notches 11 on its side, thereby realizing multiple quality grades of magnetic rings. When the user only needs to sort out qualified and unqualified, the two side chains 3 rotate in opposite directions. Thus, the user can not only complete the multiple quality grades of magnetic rings, but also perform quality detection on two groups of magnetic rings at the same time through the two chains 3, thereby improving the detection efficiency of magnetic rings.

[0043] When the transfer seat 5 moves the magnetic ring to the position of notch 2 10 or notch 3 11, the lever 14 and straight plate 17 at the telescopic end of cylinder 13 will position the magnetic ring between them, thereby preventing the magnetic ring from coming out of the receiving groove 6 due to inertia. When it is necessary to remove the magnetic ring from notch 2 10 or notch 3 11, cylinder 13 drives the connecting plate 16 and straight plate 17 to move together through lever 14 until the magnetic ring is carried by the two to the guide plate 18. Thus, the magnetic ring can slide away from the base 1 and tray 2 along the guide plate 18. Thus, the user only needs to place the receiving frame on the side of the guide plate 18 away from the baffle 8 to collect it, which makes the collection convenient for the user.

[0044] When the chain 3 moves under the drive of the gear, the support plate 4 and the limiting plate 19 restrict the chain 3 from approaching the baffle 8, so that the transfer seat 5 on the surface of the chain 3 can fit against the baffle 8, thereby ensuring that the magnetic ring in the receiving groove 6 can be smoothly dislodged from the second notch 10 or the third notch 11. At the same time, the support wheels on the surface of the limiting plate 19 and the support plate 4 also reduce the friction between the chain 3 and the limiting plate 19 and the support plate 4 when the chain 3 moves. The support ring 21 at the bottom of the tray 2 can also provide support for the transfer seat, preventing the chain 3 from tilting due to force on one side.

[0045] When a user needs to test magnetic rings of different diameters, the user can loosen the bolts to disengage the clamping plate 22 from the transfer seat 5. At this time, the user can replace the transfer seat 5 so that the receiving groove 6 on its surface matches the magnetic ring to be tested. Then, the pressing block 23 on the surface of the clamping plate 22 is inserted into the groove 24 on the surface of the transfer seat 5, thereby locking the transfer seat 5. The elasticity of the clamping plate 22 clamps the transfer seat 5, making it convenient for the user to loosen the bolts and replace the transfer seat 5.

[0046] When a magnetic ring to be tested needs to be conveyed to the two notches 9, the conveyor belt 15 first sends the magnetic ring to be tested to the distribution plate 27 at the transfer table 26, and it is engaged in the transfer groove 29 on the surface of the distribution plate 27. Then the distribution plate 27 rotates, moving the magnetic ring to be tested in one transfer groove 29 to one side so that it is on the roller conveyor 25, while the transfer groove 29 on the other side rotates to the conveyor belt 15 and receives the next magnetic ring to be tested. Then the distribution plate 27 resets, and the transfer groove 29 that just received the magnetic ring to be tested will transfer the magnetic ring to be tested to the other roller conveyor 25 as the distribution plate 27 rotates. This completes the process of conveying the magnetic rings to be tested at the conveyor belt 15 to the roller conveyors 25 on both sides. At the same time, when the roller conveyors are full of magnetic rings to be tested, the distribution plate 27 can still rotate normally, avoiding jamming due to too many magnetic rings to be tested. When the magnetic rings to be tested are conveyed to the gap 9, the cylinder 30 is activated, pushing the magnetic rings to be tested into the receiving groove 6 on the surface of the transfer seat 5. At the same time, the telescopic end of the cylinder 30 will also block the end of the roller conveyor 25 near the gap 9, thereby preventing multiple magnetic rings to be tested from entering the gap 9 and causing the gap 9 to be blocked.

[0047] When the distribution plate 27 rotates, the side plate 32 on the top surface of the support platform 31 will restrict the magnetic ring in the transfer groove 29, preventing it from being thrown away from the transfer groove 29 due to centrifugal force.

[0048] When the distribution plate 27 needs to be driven to rotate, the servo motor will drive the drive rod 36 to rotate. The rotating drive rod 36 will then drive the distribution plate 27 to rotate through the slot 37 on the surface of the distribution plate 27. During the rotation of the distribution plate 27, the pressure plate 40 and the support plate 38 will clamp the distribution plate under the pressure of the nut 41, thus preventing the distribution plate 27 from coming off the drive rod 36. When the user replaces the transfer seat 5 due to a change in the diameter of the magnetic ring to be tested, the user also needs to replace the distribution plate 27. At this time, the user needs to unscrew the nut 41 on the surface of the stud to remove it from the stud surface. Then the user removes the pressure plate 40 and the distribution plate 27 and replaces them. Since the cross-section of the drive rod 36 is rectangular, when the user inserts the slot 37 on the surface of the newly replaced distribution plate 27 into the drive rod 36, the position of the distribution plate 27 can be easily adjusted, so that one of the two transfer grooves 29 on the surface of the distribution plate 27 is aligned with the conveyor belt 15 and the other with the roller conveyor 25, thus facilitating the user's installation.

[0049] When the user needs to tighten the nut 41, the user can rotate the rotating plate 34 in the rotating groove 33 aligned with the slot 35, so that the rotating plate 34 is locked into the slot 35, thereby restricting the rotation of the distribution plate 27 and the drive rod 36, thus making it easier for the user to unscrew the nut 41. After replacement, the user needs to rotate the rotating plate 34 back into the rotating groove 33. At this time, since the rotating plate 34 is made of magnet, the rotating plate 34 will be attracted into the rotating groove 33, thereby avoiding interference with the rotation of the distribution plate 27.

[0050] When a user needs to test magnetic rings of different diameters, the user needs to screw the threaded rod 44 at the connecting seat 43 according to the diameter of the magnetic ring, thereby moving the arc plate 42 closer to the baffle 8, so that the gap between the arc plate 42 and the baffle 8 allows only one magnetic ring to pass through, thereby preventing multiple magnetic rings from entering the notch 9 and causing the transfer seat 5 at the notch 9 to be stuck.

[0051] When the transfer trough 29 rotates with the magnetic ring to the roller conveyor 25, the guide tube 46 will introduce gas into the air outlet 45 and blow it onto the magnetic ring in the transfer trough 29, making it easier for the magnetic ring to detach from the transfer trough 29 and preventing the magnetic ring from getting stuck in the transfer trough 29.
