DETAILED DESCRIPTION

[0030] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0031] This embodiment provides a surface magnetic detection device, such as Figures 1 to 12 As shown, it includes a workbench 1, a material transport channel 2, a moving component 3, a detection component 4, a material throwing component 5 and a control component; the material transport channel 2 is arranged on the workbench 1, and is used to convey the fixture 6 equipped with the magnetic component to be detected; the moving component 3 is arranged on the workbench 1, and the detection component 4 is arranged on the moving component 3 and is located above the material transport channel 2, and is used to perform surface magnetic detection on the magnetic component on the fixture 6; the material throwing component 5 is arranged on the workbench 1, and is used to carry unqualified magnetic components detected by the detection component 4; the control component is electrically connected to and controls the material transport channel 2, the moving component 3, the detection component 4 and the material throwing component 5.

[0032] In this embodiment, a detection component 4 and a material throwing component 5 are set at different positions of the material transport channel 2, and a control component is used to control the transmission magnetic component of the material transport channel 2, the surface magnetic detection of the detection component 4 and the handling of unqualified magnetic components of the material throwing component 5, so as to realize an automated process, and can perform continuous and rapid surface magnetic detection, thereby significantly improving the detection efficiency. Compared with manual detection, it can more accurately measure the magnetic field strength, reduce the situation of misjudgment and missed detection, and improve product quality. Automated detection reduces dependence on manual labor, reduces labor costs, and also reduces the labor intensity of workers and improves production safety. The entire detection process is uniformly controlled by the control component, which can ensure the consistency of the detection standards. By adjusting the parameters and procedures of the control component, it can flexibly adapt to the detection requirements of magnetic components of different types and specifications, thereby improving the versatility and flexibility of the equipment. The detection component 4 of this embodiment adopts the TM901PRO_V100 probe, which can collect the Gaussian value of the magnetic component and feed it back to the control component. Other devices can also be used in other embodiments.

[0033] like Figures 3 and 4 As shown, the material transport channel 2 includes a guide rail 20, a bracket 21, a transmission wheel 22, and a belt 23. The bracket 21 is set on the workbench 1, and two guide rails 20 are mounted in parallel on the bracket 21. The two guide rails 20 are respectively provided with a transmission wheel 22, and two belts 23 are respectively mounted on the transmission wheels 22. The fixture 6 is placed on the belt 23 between the two guide rails 20. In this embodiment, the two parallel guide rails 20 and the corresponding transmission wheels 22 can accurately control the movement trajectory of the belt 23, so that the fixture 6 can move along the predetermined path and speed, ensuring the accuracy of the detection position.

[0034] like Figure 4 and Figure 6 As shown, the apparatus further includes a first stopper 24 and a first limiting cylinder 25. The first limiting cylinder 25 is disposed on the guide rail 20 in front of the material transport channel 2 along the conveying direction of the material transport channel 2. The output end of the first limiting cylinder 25 is vertically upward, and the first stopper 24 is disposed at the output end of the first limiting cylinder 25 and is located between the two guide rails 20. In this embodiment, under the control of the control component, the first limiting cylinder 25 drives the first stopper 24 to rise and abut against one side of the jig 6, thereby preventing the jig 6 from continuing to move and interfering with the jig 6 undergoing surface magnetic testing. After the detection component 4 completes the surface magnetic testing of the jig 6 in the middle of the material transport channel 2, the first limiting cylinder 25 drives the first stopper 24 to descend, allowing the jig 6 to continue moving along the material transport channel 2 to the bottom of the detection component 4 for surface magnetic testing. This simple structure ensures smooth detection.

[0035] like Figure 5 and Figure 7As shown, it also includes a second limiting cylinder 27, a second stopper 26, a positioning cylinder 28 and a positioning block 29. The second limiting cylinder 27 is arranged in the middle of the material transport channel 2 along the conveying direction of the material transport channel 2, and the output end of the second limiting cylinder 27 is vertically upward. The second stopper 26 is arranged at the output end of the second limiting cylinder 27 and is located between the two guide rails 20. The positioning cylinder 28 is arranged on the workbench 1 below the second limiting cylinder 27, and the output end of the positioning cylinder 28 is vertically upward. The positioning block 29 is arranged at the output end of the positioning cylinder 28 and is located in front of the second stopper 26. The positioning cylinder 28 drives the positioning block 29 to push up and drive the jig 6 to leave the belt 23, so that the detection component 4 above the positioning block 29 can perform surface magnetic detection.

[0036] The second limiting cylinder 27 of this embodiment drives the second stopper 26 to rise and abut against one side of the jig 6, so that the jig 6 equipped with the magnetic component to be detected can initially stay at the detection station in the middle of the material transport channel 2. At this time, the positioning cylinder 28 drives the positioning block 29 to rise, and the positioning block 29 abuts against the bottom of the jig 6 and takes the jig 6 away from the belt 23. The moving component 3 drives the detection component 4 to move above the jig 6 to perform surface magnetic detection on the magnetic component on the jig 6. Since the jig 6 at the detection station does not contact the belt 23 when the detection component 4 is performing surface magnetic detection, the jig 6 on the material transport channel 2 that has completed surface magnetic detection can continue to move along the material transport channel 2 through the belt 23. The design is ingenious. Figure 6 As shown, the first stopper 24 and the second stopper 26 of this embodiment have the same structure, and the first limiting cylinder 25 and the second limiting cylinder 27 have the same structure, which is convenient for installation.

[0037] like Figures 8 to 10 As shown, the moving assembly 3 includes an X-axis module 31 and a Z-axis module 32. The X-axis module 31 is disposed on the workbench 1, the Z-axis module 32 is disposed on the X-axis module 31, and the detection assembly 4 is disposed on the Z-axis module 32. The control assembly drives the X-axis module 31 and the Z-axis module 32 to move the detection assembly 4 to above the fixture 6 on the positioning block 29. The Z-axis module 32 drives the detection assembly 4 to abut against the magnetic component to be detected on the fixture 6. In this embodiment, the X-axis module 31 and the Z-axis module 32 enable the detection assembly 4 to be accurately moved above the fixture 6 on the positioning block 29 and precisely abut against the magnetic component to be detected. Furthermore, by precisely controlling the movement of the X-axis module 31 and the Z-axis module 32, the detection assembly 4 can be ensured to maintain a stable position and posture during the detection process. This helps reduce detection errors caused by position offset or posture changes, thereby improving the accuracy and reliability of detection.

[0038] like Figure 9As shown, the X-axis module 31 includes a first gantry 310, a first servo motor 311, a first slide rail 312, a first screw rod 313 and a first slider 314. The first gantry 310 is arranged on the workbench 1, the first servo motor 311 and the first slide rail 312 are arranged on the first gantry 310, the first screw rod 313 is arranged in the first slide rail 312, the first screw rod 313 is rotatably connected to the output end of the first servo motor 311, the first slider 314 is arranged on the first screw rod 313, and the Z-axis module 32 is arranged on the first slider 314. The first servo motor 311 drives the first screw rod 313 to drive the Z-axis module 32 on the first slider 314 to slide along the first slide rail 312, and the sliding direction of the Z-axis module 32 is parallel to the material transport channel 2.

[0039] In this embodiment, the first gantry 310 is mounted on the workbench 1 and can be adjusted to accommodate the size and shape of the workbench 1. By controlling the servo motor, precise position control of the first slider 314 and the Z-axis module 32 thereon can be achieved. The first slide rail 312 provides a stable sliding track for the first slider 314, ensuring that the Z-axis module 32 remains stable as it slides along the material transport channel 2. This also ensures that the detection assembly 4 maintains its correct position during the detection process, thereby improving detection efficiency and reliability.

[0040] like Figure 10 As shown, the Z-axis module 32 includes a connecting plate 320, a detection cylinder 321 and a mounting plate 322. The connecting plate 320 is arranged on the first slider 314, the detection cylinder 321 is arranged on the connecting plate 320, the output end of the detection cylinder 321 is vertically downward, the mounting plate 322 is arranged at the output end of the detection cylinder 321, the detection component 4 is arranged on the mounting plate 322, and the detection cylinder 321 drives the detection component 4 on the mounting plate 322 to press down against the magnetic component to be detected on the fixture 6. In this embodiment, the Z-axis module 32 is fixed to the first slider 314 of the X-axis module 31 through the connecting plate 320, so that the Z-axis module 32 can move flexibly according to the position change of the X-axis module 31. The adjustability of the detection cylinder 321 enables the detection component 4 on the mounting plate 322 to adapt to the detection requirements of different heights and positions, thereby enhancing flexibility.

[0041] like Figure 11 and Figure 12As shown, the throwing assembly 5 includes a second gantry 50, a transport cylinder 51, a suction block 510 and a swing plate 52. The second gantry 50 is arranged on the workbench 1 behind the transport channel 2 along the conveying direction of the transport channel 2. The transport cylinder 51 is slidably arranged on the second gantry 50. The sliding direction of the transport cylinder 51 is perpendicular to the guide rail 20. The output end of the transport cylinder 51 is vertically downward. The suction block 510 is arranged at the output end of the transport cylinder 51. The swing plate 52 is arranged on the workbench 1. The transport cylinder 51 drives the suction block 510 to press down and absorb the unqualified magnetic components detected by the detection assembly 4 and transport them to the swing plate 52. The throwing assembly 5 of this embodiment realizes the automatic transportation of unqualified magnetic components. When the detection assembly 4 detects unqualified products, the transport cylinder 51 can respond quickly, drive the suction block 510 to press down and absorb the unqualified products, and then transport them to the swing plate 52, reducing the time and error rate of manual sorting. In this embodiment, a material transfer module 8 is further provided on the workbench 1, and a swing plate 52 is provided on the material transfer module 8. The material transfer module 8 can drive the swing plate 52 to move, so that unqualified magnetic components can be placed at different positions of the swing plate 52. This can be easily achieved by those skilled in the art and will not be explained in detail.

[0042] like Figure 11 and Figure 12 As shown, it also includes a second servo motor 53, a second slide rail 54, a second screw rod 55 and a second slider 56. The second servo motor 53 and the second slide rail 54 are arranged on the second gantry 50, the second screw rod 55 is arranged in the second slide rail 54, the second screw rod 55 is rotatably connected to the output end of the second servo motor 53, the second slider 56 is arranged on the second screw rod 55, and the transport cylinder 51 is arranged on the second slider 56. The second servo motor 53 drives the second screw rod 55 to drive the transport cylinder 51 on the second slider 56 to slide along the second slide rail 54, and the sliding direction of the transport cylinder 51 is perpendicular to the guide rail 20. In this embodiment, the second servo motor 53 can accurately control the rotation of the second screw rod 55, thereby driving the second slider 56 and the transport cylinder 51 thereon to slide along the second slide rail 54 to a specified position, ensuring that the transport cylinder 51 can be accurately positioned above the unqualified magnetic component, thereby improving the accuracy and reliability of the transport.

[0043] like Figure 11 and Figure 12 As shown, it also includes a first pushing cylinder 57, a second pushing cylinder 58 and a placement table 59. The placement table 59 is arranged on the workbench 1, and the first pushing cylinder 57 and the second pushing cylinder 58 are arranged on both sides of the guide rail 20. The movement direction of the output end of the first pushing cylinder 57 and the second pushing cylinder 58 is perpendicular to the guide rail 20. The first pushing cylinder 57 and the second pushing cylinder 58 are used to drive the jig 6 equipped with unqualified magnetic components to move to the placement table 59, and the transport cylinder 51 is used to transport the unqualified magnetic components to the swing plate 52.

[0044] The output ends of the first pushing cylinder 57 and the second pushing cylinder 58 of this embodiment are respectively provided with a first pushing plate 570 and a second pushing plate 580. After being inspected by the inspection component 4, the jig 6 will continue to move to the rear of the material transport channel 2. When passing between the first pushing cylinder 57 and the second pushing cylinder 58, if there is an unqualified magnetic component on the jig 6, the first pushing cylinder 57 and the second pushing cylinder 58 will respectively drive the first pushing plate 570 and the second pushing plate 580 to clamp the jig 6 equipped with the unqualified magnetic component and push the jig 6 onto the placement table 59. At this time, the second servo motor 53 drives the second screw rod 55 to drive the transport cylinder 51 on the second slide 56 to slide along the second slide rail 54 to the top of the jig 6 on the placement table 59, driving the suction block 510 to press down and suck up the unqualified products and transport them to the wobble plate 52. Then, the first push cylinder 57 and the second push cylinder 58 respectively drive the first push plate 570 and the second push plate 580 to clamp the jig 6 containing the remaining qualified magnetic components and push it back to the material transport channel 2. By providing the first push cylinder 57 and the second push cylinder 58, it is possible to avoid directly transporting the unqualified magnetic components on the material transport channel 2, effectively protecting the material transport channel 2 and making it easier for inspectors to inspect the unqualified magnetic components.

[0045] The control component of this embodiment can use the host computer to cooperate with the programmable logic controller to achieve precise control of the material transport channel 2, the moving component 3, the detection component 4 and the throwing component 5. This is easy to implement for those skilled in the art and will not be described in detail. In addition, a recycling channel 7 can also be added in this embodiment, such as Figure 3 As shown, the recycling channel 7 is connected to the material transport channel 2, and the jig 6 equipped with the magnetic components to be tested in other processes is transferred to the material transport channel 2 through the recycling channel 7, so that the material transport channel 2 can automatically replenish materials and realize automation.

[0046] The use process of this utility model is as follows:

[0047] The operator starts the switch of the control component, and the jig 6 equipped with the magnetic component to be tested enters the material transport channel 2 in turn. When the previous jig 6 is conveyed to the detection station along the belt 23, the second limiting cylinder 27 drives the second stopper 26 to rise to perform preliminary limiting on the jig 6 at the detection station in the middle of the material transport channel 2. The positioning cylinder 28 drives the positioning block 29 to rise and rest against the bottom of the jig 6 and push the jig 6 away from the belt 23 of the material transport channel 2. At the same time, the first limiting cylinder 25 drives the first stopper 24 to rise to limit the next jig 6 in the material transport channel 2 to avoid interference with the previous jig 6 at the detection station.

[0048] The X-axis module 31 and the Z-axis module 32 of the moving component 3 drive the detection component 4 on the Z-axis module 32 to move above the positioning block 29 of the detection station. The detection cylinder 321 of the Z-axis module 32 drives the detection component 4 on the mounting plate 322 to press down against the magnetic component to be detected on the fixture 6 for surface magnetic detection.

[0049] After the inspection is complete, the second limit cylinder 27 and the positioning cylinder 28 respectively drive the second stopper 26 and the positioning block 29 to descend. If all magnetic components pass, the previous jig 6 is transported along the belt 23 of the material transport channel 2 to the next process. If any unqualified magnetic components are found, the first push cylinder 57 and the second push cylinder 58 respectively drive the first push plate 570 and the second push plate 580 to clamp the jig 6 containing the unqualified magnetic components as it passes through the ejection mechanism behind the material transport channel 2, and push the jig 6 onto the placement table 59. At this time, the second servo motor 53 drives the second screw rod 55 to drive the transport cylinder 51 on the second slider 56 to slide along the second slide rail 54 to above the jig 6 on the placement table 59, and drives the suction block 510 to press down and suck up the unqualified products and transport them to the swing plate 52. Then the first pushing cylinder 57 and the second pushing cylinder 58 respectively drive the first push plate 570 and the second push plate 580 to clamp the jig 6 with the remaining qualified magnetic components and push it back to the transport channel 2 and transmit it to the next process along the belt 23 of the transport channel 2.

[0050] After completing the surface magnetic detection of the previous fixture 6, the first limit cylinder 25 drives the first stopper 24 to descend, so that the next fixture 6 equipped with the magnetic component to be detected is transferred to the detection station for surface magnetic detection, and this process is repeated until all surface magnetic detections are completed.

[0051] The directional terms mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive terms.
