Description

Technical Field

[0001] The present invention relates to the technical field of magnetic tomography detection, and in particular to a magnetic tomography detection device and method. Background Art

[0002] A magnetic tomography detection device is a device that uses fluxgate technology to adjust the feedback of the excitation coil to detect structural defects and determine whether it meets the requirements of use.

[0003] A search revealed a magnetic tomography detection device and method with the authorization announcement number CN117589862B. This invention utilizes the characteristic of a sudden increase in peak voltage when an internal defect in the ferromagnetic material to be tested is magnetized. By analyzing the peak voltage increment, the inflection point of the peak voltage increment is used to indicate the magnetization of the defect. The defect burial depth is determined by the current value corresponding to the inflection point and a comparison table of preset current and magnetization depth, thus achieving accurate detection of the burial depth of internal defects.

[0011] As a further technical solution of the present invention, the fixed bracket is a plate-like structure with bent ends. The fixed bracket is located in the middle of the inner surface of the fixed bracket. There are two groups of fixed brackets and they are symmetrically distributed. One group of fixed brackets corresponds to two groups of adjusting electric cylinders.

[0012] As a further technical solution of the present invention, the length of the support rod is equal to the width of the conveyor belt, the number of support rods between the two groups of limit rings is several groups and distributed in a ring array, the number of universal balls corresponding to one group of limit rings is several groups and distributed in a ring array, the universal balls and the rollers are rolled in connection, and the slide rails are parallel to the rollers.

[0017] A method for using a magnetic tomography detection device, comprising the following steps:

[0018] Step 1: Adjust the conveyor belt: Adjust the distance between the two conveyor belts according to the size of the conveyed items. The distance between the two conveyor belts can be adjusted by extending or contracting the electric cylinder through electronic control.

[0019] Step 2: Conveying: After adjusting the conveyor belt, start the device. The motor starts immediately and drives the roller to rotate. The rotation of the roller drives the conveyor belt to convey the inspected items. The conveyed items are grabbed by the robot and sent to the surface conveying end of the conveyor belt.

[0020] Step 3: Detection: The inspection object is transported from the conveying end to the inner side of the detection component via the conveyor belt, and the conveyed object is detected by the excitation detection coil inside the detection component;

[0021] Step 4: Rejection: After the inspection is completed, the items continue to be transported by the conveyor belt. When qualified products are delivered to the output end, they are grabbed by the robot and transported to the next process. When unqualified products are delivered to the center of the lifting structure, the electric telescopic rod is extended to lift the items through the top plate and the sliding plate, so that the conveyed items are suspended in the air. At this time, the cylinder is pushed to extend and the movable plate is moved. The unqualified products are pushed to the surface of the guide plate and roll down through the movable plate. The unqualified products are placed in the container to complete the rejection.

[0022] Through the function of the adjustment structure, during use, the conveying distance between the two sets of conveyor belts can be adjusted according to the needs of the different sizes of the conveyed inspection items, so as to meet the conveying inspection of items of different sizes. A thinner conveyor belt will greatly reduce the impact on the conveying results, and can make the inspection results more accurate.

[0023] Through the coordinated action of the lifting structure, fixed plate, pushing cylinder, movable plate and guide plate, unqualified products can be lifted up during use. With the coordinated action of the movable plate and other structures, unqualified products can be pushed out and removed. At the same time, the size of the lifting surface area can be adjusted according to the different spacing between the two sets of conveyor belts, thereby achieving the effect of adaptive adjustment.

[0024] In summary, the principle process of the present invention is as follows:

[0025] When in use, the spacing between the two sets of conveyor belts is adjusted according to the size of the conveyed items, and the spacing between the two sets of conveyor belts is adjusted by extending or contracting the electrically controlled electric cylinder. During adjustment, when conveying larger items for inspection, the electric cylinder can be controlled to push and extend, and the limit ring is moved by the electric cylinder. The two sets of limit rings and the support rod follow the movement, and the two ends of the conveyor belts are driven away from each other on the surface of the roller by the limit ring. At this time, the spacing between the two sets of conveyor belts becomes larger, and when it needs to be reduced, the adjustment can be completed by simply controlling the electric cylinder to contract. The ball of the universal ball can be made to roll with the roller through the action of the universal ball. The adjustment process can be carried out when the device is stopped, and the adjustment can be carried out during the operation of the device, which is conducive to improving the working efficiency of the device and is extremely convenient.

[0026] After adjusting the conveyor belt, start the device. The motor starts immediately and drives the roller to rotate. The rotation of the roller drives the conveyor belt to transport the inspected items. The conveyed items are grabbed by the manipulator and sent to the surface conveying end of the conveyor belt.

[0027] The inspection object is transported from the conveying end to the inner side of the inspection component by the conveyor belt. The conveyed object is inspected by the excitation detection coil inside the inspection component to determine whether the current inspection object meets the requirements;

[0028] After the inspection is completed, the items continue to be transported by the conveyor belt. When qualified products are delivered to the output end, they are grabbed by the robot and transported to the next process. When unqualified products are delivered to the center upper end of the jacking structure, the electric telescopic rod is extended to lift the items through the top plate and the sliding plate, so that the conveyed items are suspended in the air. At this time, the push cylinder is extended to push the movable plate to move, and the unqualified products are pushed to the surface of the guide plate by the movable plate to roll down, and the unqualified products are placed in the container to complete the removal.

[0029] It should be noted that after the spacing between the two sets of conveyor belts is adjusted, the fixed-size top plate or sliding plate may not be able to pass through the space between the two sets of conveyor belts, or the shorter supported items may not be able to maintain their stability. At this time, the movable block can be controlled to move upward by the pushing of the supporting cylinder, and the connecting rod can be driven by the movable block to push the sliding plate away from the center position of the top plate. At this time, the supporting surface of the sliding plate together with the top plate is increased, so that the space with a large distance between the two sets of conveyor belts can be supported. When the two sets of conveyor belts are small, the supporting cylinder can be controlled to contract, thereby driving the two sets of sliding plates to move closer to the center position of the top plate. At this time, the items with a small distance between the two sets of conveyor belts can be supported.

[0030] It should be noted that the height to which the electric telescopic rod drives the extension frame and the top plate to push the items upward is greater than the height of the items conveyed by the conveyor belt, and the force used to push the cylinder to drive the movable plate to push the items requires the items to be moved to the upper end of the guide plate, forming a parabolic drop.

[0031] The working principle and beneficial effects of the present invention are:

[0032] 1. In the present invention, through the function of the adjustment structure, during use, the conveying distance between the two sets of conveyor belts can be adjusted according to the needs of the different sizes of the conveyed inspection objects, thereby meeting the conveying inspection of objects of different sizes. A thinner conveyor belt will greatly reduce the impact on the conveying results, and can make the inspection results more accurate.

[0033] 2. In the present invention, through the coordinated action of the lifting structure, fixed plate, pushing cylinder, movable plate and guide plate, unqualified products can be lifted up during use, and the unqualified products can be pushed out by the coordinated action of the movable plate and other structures. At the same time, the size of the lifting surface area can be adjusted according to the different spacing between the two groups of conveyor belts, thereby achieving the effect of adaptive adjustment.

[0050] Example 2

[0051] like Figures 4 to 6 As shown, on the basis of Example 1, a lifting structure 6 is further proposed, which includes a bottom bracket 61 fixedly connected to the outer surface of the main bracket 1, the surface of the bottom bracket 61 is fixedly connected to an electric telescopic rod 62, the output end of the electric telescopic rod 62 is fixedly connected to an extension frame 63, the inner side of the extension frame 63 is connected to a supporting cylinder 64, the output end of the supporting cylinder 64 is fixedly connected to a movable block 65, the top of the extension frame 63 is fixedly connected to a top plate 66, a sliding groove 67 is provided on the surface of the top plate 66, and a sliding plate 68 is slidably connected to the inner side of the sliding groove 67 on the outer surface of the top plate 66, the upper end of the sliding plate 68 is fixedly connected to an anti-slip block 69, and a connecting rod 60 is hinged between the movable block 65 and the sliding plate 68.

[0052] The bottom bracket 61 is fixedly connected to the main bracket 1 by bolts, and the end of the electric telescopic rod 62 away from the output is fixedly connected to the bottom bracket 61 by bolts. The surface of the extension frame 63 is provided with two groups of openings for the connecting rod 60 to pass through. Both ends of the connecting rod 60 are respectively connected to the movable block 65 and the sliding plate 68 by hinges.

[0053] The sliding plate 68 slides back and forth along the length direction of the slide groove 67, and the sliding plate 68 is extended or contracted by the support cylinder 64 to adjust it away from the top plate 66 or close to the center of the top plate 66. There are two groups of connecting rods 60 corresponding to a set of movable blocks 65 and they are symmetrically distributed. There are two groups of lifting structures 6 and they are symmetrically distributed. The connecting line between the two groups of lifting structures 6 is parallel to the conveying direction of the conveyor belt 4.

[0054] There are two groups of pushing cylinders 9. The output end of the pushing cylinder 9 passes through the fixed plate 8. The movable plate 10 is used to detect the surface of the corresponding detection object entering the guide plate 11. The guide plate 11 is set as an oblique structure on the surface of the main bracket 1.

[0055] In this embodiment, during use, unqualified products can be lifted up, and with the help of structures such as the movable plate 10, unqualified products can be pushed up and removed. At the same time, the size of the lifting surface area can be adjusted according to the different spacing between the two groups of conveyor belts 4, thereby achieving an adaptive adjustment effect.

[0056] After the inspection is completed, the items continue to be transported through the conveyor belt 4.

At this time, the movable block 65 can be controlled to move upward by the pushing of the support cylinder 64, and the connecting rod 60 is driven by the movable block 65 to push the sliding plate 68 away from the center position of the top plate 66. At this time, the supporting surface of the sliding plate 68 together with the top plate 66 is increased, so that the space with a larger distance between the two groups of conveyor belts 4 can be supported. When the two groups of conveyor belts 4 are smaller, the support cylinder 64 can be controlled to contract, thereby driving the two groups of sliding plates 68 to move closer to the center position of the top plate 66.

[0060] Step 2: Conveying: After adjusting the conveyor belt 4, start the device. At this time, the motor 7 starts immediately, driving the roller 2 to rotate. The conveyor belt 4 is driven by the roller 2 to convey the inspection object. The conveyed object is grabbed by the manipulator and sent to the surface conveying end of the conveyor belt 4.

[0061] Step 3: Detection: The detection object is transported from the conveying end to the inner side of the detection component 3 via the conveyor belt 4, and the conveyed object is detected by the excitation detection coil 12 inside the detection component 3;

[0062] Step 4: Rejection: After the inspection is completed, the items continue to be transported through the conveyor belt 4. When qualified products are transported to the output end, they are grabbed by the robot and transported to the next process. When unqualified products are transported to the center upper end of the jacking structure 6, the electric telescopic rod 62 is extended to lift the items through the top plate 66 and the sliding plate 68, so that the conveyed items are suspended in the air. At this time, the push cylinder 9 is extended to push the movable plate 10 to move, and the unqualified products are pushed to the surface of the guide plate 11 by the movable plate 10 to roll down, and the unqualified products are placed in the container to complete the rejection.

[0063] In summary, the principle process of the present invention is as follows:

[0064] When in use, the distance between the two groups of conveyor belts 4 is adjusted according to the size of the conveyed items, and the distance between the two groups of conveyor belts 4 is adjusted by extending or contracting the electrically controlled adjusting cylinder 53. During adjustment, when conveying larger items for inspection, the adjusting cylinder 53 can be controlled to push and extend, and the limiting ring 54 can be moved by the adjusting cylinder 53. The two groups of limiting rings 54 and the support rod 55 follow the movement, and the two ends of the conveyor belt 4 are driven to move away from each other on the surface of the roller 2 through the limiting ring 54. At this time, the distance between the two groups of conveyor belts 4 becomes larger, and when it needs to be reduced, it is only necessary to control the adjusting cylinder 53 to contract to complete the adjustment. The ball 56 can be used to make the ball 56 roll with the roller 2. This adjustment process can be carried out when the device is stopped, and can be adjusted during the operation of the device, which is conducive to improving the working efficiency of the device and is extremely convenient.

[0065] After the conveyor belt 4 is adjusted, the device is started. At this time, the motor 7 is immediately started to drive the roller 2 to rotate. The conveyor belt 4 is driven by the roller 2 to transport the inspection object. The conveyed object is grabbed by the manipulator and sent to the surface conveying end of the conveyor belt 4.

[0066] The inspection object is transported from the conveying end to the inner side of the inspection component 3 by the conveyor belt 4. The conveyed object is inspected by the excitation detection coil 12 inside the inspection component 3 to determine whether the current inspection object meets the requirements;

[0067] After the inspection is completed, the items continue to be transported through the conveyor belt 4. When qualified products are transported to the output end, they are grabbed by the robot and transported to the next process. When unqualified products are transported to the center upper end of the lifting structure 6, the electric telescopic rod 62 is extended to lift the items through the top plate 66 and the sliding plate 68, so that the conveyed items are suspended in the air. At this time, the push cylinder 9 is extended to push the movable plate 10 to move, and the unqualified products are pushed to the surface of the guide plate 11 by the movable plate 10 to roll down, and the unqualified products are placed in the container to complete the removal.

[0068] It should be noted that after the spacing between the two sets of conveyor belts 4 is adjusted, the fixed-size top plate 66 or sliding plate 68 may not be able to pass through between the two sets of conveyor belts 4, or the shorter supported articles may not be able to maintain their stability. At this time, the movable block 65 can be controlled to move upward by the pushing of the supporting cylinder 64, and the connecting rod 60 is driven by the movable block 65 to push the sliding plate 68 away from the center position of the top plate 66. At this time, the supporting surface of the sliding plate 68 together with the top plate 66 is increased, so that the space between the two sets of conveyor belts 4 with a larger spacing is supported. When the two sets of conveyor belts 4 are smaller, the supporting cylinder 64 can be controlled to contract, thereby driving the two sets of sliding plates 68 to move closer to the center position of the top plate 66. At this time, the articles with a smaller spacing between the two sets of conveyor belts 4 can be supported.

[0069] It should be noted that the height to which the electric telescopic rod 62 drives the extension frame 63 together with the top plate 66 to push the items upward is greater than the height to which the conveyor belt 4 conveys the items, and the force used to push the cylinder 9 to drive the movable plate 10 to push the items is large enough to move the items to the upper end of the guide plate 11, forming a parabolic drop.

[0070] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
