Detailed implementation manners

[0026] The following will describe the technical solutions in some embodiments of the present application with reference to the accompanying drawings in some embodiments of the present application.

[0027] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0028] Such as Figure 1As shown in the figure, an embodiment of the present application provides a magnetic field adjusting device, which includes a container 1 capable of accommodating a magnetic material to be detected and two sets of adjusting mechanisms. The two sets of adjusting mechanisms are respectively arranged on both sides of the container 1 in the horizontal direction. A plurality of magnetic circuit boards 11 are respectively arranged on both sides of the container 1, and each magnetic circuit board 11 is detachably connected to the container 1, so as to realize the adjustment of the magnetic environment around the container 1, and further provide different magnetic environments for the magnetic material to be detected. During the process of adjusting the number of magnetic circuit boards 11, the embodiment of the present application is controlled by the adjusting mechanism, reducing the need for operators to manually move the magnetic circuit boards 11 and reducing the problem of pinching hands. The first driving mechanism 2 in the adjusting mechanism can drive the connecting plate 21 to move, and the magnetic circuit board 11 can be detachably connected to the connecting plate 21. When it is necessary to strengthen the magnetic field, the magnetic circuit board 11 can be installed on the connecting plate 21, and then the first driving mechanism 2 is driven to make the magnetic circuit board 11 move towards the container 1. The magnetic circuit board 11 can fit on the container 1 to strengthen the magnetic field. When there is a magnetic circuit board 11 outside the container 1, the magnetic circuit board 11 on the connecting plate 21 can be made to fit with the magnetic circuit board 11 outside the container 1 to strengthen the magnetic field. When it is necessary to weaken the magnetic field, the magnetic circuit board 11 on the container 1 can be connected to the connecting plate 21, and then the magnetic circuit board 11 is made to move away from the container 1 through the first driving mechanism 2 to achieve the purpose of weakening the magnetic field, ultimately achieving the purpose of adjusting the magnetic environment around the container 1. In addition, the connecting plate 21 and the magnetic circuit board 11 can be detachably connected, and the connecting plate 21 is driven to move by the first driving mechanism 2, avoiding the problem of pinching hands during the operation process.

[0029] As Figure 1 shown, as an implementation manner, a plurality of first through holes 211 are provided on the connecting plate 21, and second through holes 111 corresponding to the first through holes 211 are provided on the magnetic circuit board 11. The adjusting mechanism further includes an adjusting member (not shown in the figure), and the adjusting member can pass through the first through holes 211 and the second through holes 111 and be threadedly connected to the second through holes 111. In this way, when it is necessary to strengthen the magnetic field environment, first take a magnetic block and fit it on the connecting plate 21, and then the adjusting member passes through the first through holes 211 and is threadedly connected to the second through holes 111 to realize the connection between the magnetic circuit board 11 and the connecting plate 21. Then, the first driving mechanism 2 is driven to make the connecting plate 21 move towards the container 1, so that the magnetic circuit board 11 is magnetically connected to the container 1 or connected to the magnetic circuit board 11 outside the container 1, and then the adjusting member is disassembled, thereby achieving the purpose of increasing the magnetic field. When disassembling the magnetic circuit board 11, the adjusting member passes through the first through holes 211 and the second through holes 111, and drives the connecting plate 21 to move away from the container 1, so that the magnetic circuit board 11 is separated from the container 1 or the magnetic circuit board 11 outside the container 1.

[0030] Optionally, the connecting plate 21 is not magnetically connected to the magnetic circuit board 11, which facilitates the separation of the connecting plate 21 from the magnetic circuit board 11 and also avoids the problem of pinching hands between the magnetic circuit board 11 and the connecting plate 21.

[0031] Optionally, the adjusting member can be a bolt, and the end head of the bolt has a threaded section that can be threadedly connected to the magnetic circuit board 11.

[0032] Optionally, four first through holes 211 can be provided to improve the stability between the connecting plate 21 and the magnetic circuit board 11.

[0033] As Figure 2 shown, optionally, the magnetic field adjusting device further includes a plurality of guide rods 4. The guide rods 4 penetrate through a plurality of magnetic circuit boards 11 and are connected to the second pressing block 18. In this way, the magnetic circuit boards 11 can move along the guide rods 4.

[0034] As Figure 1 and 5 shown, as an implementation manner, a magnetic isolation plate 12 is provided between two adjacent magnetic circuit boards 11. The magnetic isolation plate 12 can be threadedly connected to the adjusting member. By providing the magnetic isolation plate 12, the magnetic environment can also be adjusted, weakening the magnetism between two adjacent magnetic circuit boards 11, further reducing the problem of magnetic materials to be detected. In addition, it is also convenient for the installation and disassembly of the magnetic circuit boards 11, avoiding the problem of taking away other magnetic circuit boards 11 during the disassembly process.

[0035] Optionally, when there are multiple magnetic circuit boards 11 outside the accommodating body 1, if only the outermost magnetic circuit board 11 is to be disassembled, the adjusting member can be threadedly connected only to the outermost magnetic circuit board 11. In this way, when the connecting plate 21 moves away from the accommodating body 1, the problem of taking away other magnetic circuit boards 11 can be avoided; of course, if multiple magnetic circuit boards 11 are to be disassembled, the adjusting member can pass through the second through holes 111 on multiple magnetic circuit boards 11 until it is threadedly connected to the magnetic circuit board 11 to be disassembled, so that multiple magnetic circuit boards 11 can be disassembled simultaneously.

[0036] Optionally, the magnetic isolation plate 12 can be an aluminum plate.

[0037] As Figure 1 and 2 shown, as an implementation manner, the adjusting mechanism further includes a support base 22 and a support arm 23 provided on the support base 22. The adjusting mechanism includes a first lead screw 24 and a guide rod 25 fixed on the support arm 23. Both the first lead screw 24 and the guide rod 25 are connected to the connecting plate 21. By driving the first lead screw 24, the connecting plate 21 and the guide rod 25 can move relative to the support arm 23, thereby realizing the installation and disassembly of the magnetic circuit board 11.

[0038] Optionally, two guide rods 25 may be provided, respectively on both sides of the first lead screw 24. On the one hand, they play a supporting role, and on the other hand, they play a guiding role. At the same time, several balls may be provided in the through holes of the support arm 23 through which the guide rods 25 pass to facilitate the sliding of the guide rods 25, so as to further facilitate the movement of the connecting plate 21 when driving the first lead screw 24 to move.

[0039] Optionally, a rocker arm is installed at the end of the first lead screw 24, and by manually rocking the rocker arm, the first lead screw 24 can be moved.

[0040] As Figures 3 to 5 shown, as an implementation manner, a receiving groove 16 for receiving the magnetic material to be detected is provided at the middle position of the receiving body 1, and two blocking strips 15 are provided on each side of the receiving groove 16; the receiving body 1 further includes two first pressing blocks 17 arranged in the vertical direction, and the two first pressing blocks 17 are used to fix the blocking strips 15. Through the two blocking strips 15 and the two first pressing blocks 17, a receiving groove 16 with a closed perimeter is formed; the receiving body 1 further includes two second pressing blocks 18 arranged in the horizontal direction, and the two second pressing blocks 18 are both connected to the two first pressing blocks 17. By providing the two second pressing blocks 18, the two first pressing blocks 17 are fixed, improving the overall stability.

[0041] Optionally, the first pressing block 17 and the second pressing block 18 may be connected by bolts.

[0042] Optionally, the blocking strips 15, the first pressing blocks 17, and the second pressing blocks 18 may all be made of stainless steel.

[0043] As Figure 1 and 3 shown, optionally, the magnetic field adjusting device further includes a push rod 8. When the magnetic material to be detected is placed at the entrance position of the receiving groove 16, it can be pushed into the center position of the receiving groove 16 by the push rod 8.

[0044] As Figure 1 , 3 , 4 and 5 shown, as an implementation manner, one magnet 14 is respectively provided outside the two second pressing blocks 18, so as to provide a magnetic environment for the magnetic material to be detected in the receiving groove 16, and outside the magnet 14 is a magnetic circuit board 11, and the magnetic circuit board 11 is used to adjust the magnetic field strength. Two blocking blocks 19 arranged in the up and down direction are provided at the opening position of the receiving groove 16. The blocking block 19 includes a convex portion 191 protruding in the direction of the magnet 14. By providing the convex portion 191, the opening of the receiving groove 16 can be at a certain distance away from the magnet 14. In this way, when the magnetic material to be detected is put into the receiving groove 16, it can be avoided that the magnet 14 sucks away the magnetic material, making it difficult to put it into the receiving groove 16.

[0045] AsFigure 5 As shown, optionally, two additional magnetic circuit blocks 13 can be respectively and additionally provided at the upper and lower ends of the magnet 14 on the same side, so that the magnet 14, the magnetic circuit blocks 13, and the magnetic circuit board 11 on the same side form a complete magnetic path.

[0046] Optionally, the magnet 14 can be connected to the second pressing block 18 by bolts, and the guide rod 4 passes through the magnetic circuit board 11, the magnetic circuit blocks 13, and the first pressing block 17 on the same side.

[0047] As Figure 4 and 5 shown, as an implementation manner, baffles 20 are provided on both the front and rear sides of the magnet 14. By providing the baffles 20, the problem of magnetic leakage of the magnet 14 can be reduced.

[0048] Optionally, two baffles 20 are provided on both the front and rear sides of the magnet 14 on the same side.

[0049] As Figures 1 to 3 shown, as an implementation manner, the magnetic field adjustment device further includes a conveying mechanism. The conveying mechanism is fixed on the support base 22. The conveying mechanism includes two guide columns 3 and a slider 31. The slider 31 can slide along the guide column 3. Two sliders 31 located on different guide columns 3 are connected to a drag plate 32. Two connecting pipes 7 are fixed to the lower end surface of the drag plate 32. The two connecting pipes 7 are connected to the accommodating body 1. In this way, when the drag plate 32 is driven to slide and the slider 31 slides relative to the guide column 3, the smoothness of the movement of the drag plate 32 is improved. And the two connecting pipes 7 fixed to the lower end surface of the drag plate 32 move synchronously with the drag plate 32, further realizing the synchronous movement of the driven drag plate 32 and the accommodating body 1. Thus, the conveying mechanism can convey the accommodating body 1 into the constant temperature furnace 5, and provide a temperature change environment for the magnetic material to be detected through the existing constant temperature furnace 5, reducing the cost of manual handling.

[0050] Optionally, the conveying mechanism is fixed at one end of the support base 22 away from the constant temperature furnace 5. In this way, the accommodating body 1 can be conveyed into the constant temperature furnace 5.

[0051] Optionally, the connection between the connecting pipe 7 and the accommodating body 1 is achieved through a tray 33.

[0052] As Figure 2 shown, as an implementation manner, the conveying mechanism further includes a second lead screw 34. The second lead screw 34 is connected to the drag plate 32. By rotating the second lead screw 34, the second lead screw 34 can drive the drag plate 32 to move. And the slider 31 slides along the guide column 3, which can improve the smoothness and operation efficiency.

[0053] Optionally, a handwheel is installed at the end of the second lead screw 34. By driving the handwheel, the guide block in the second lead screw 34 can slide along the guide rail, and the guide block is connected to the carriage 32 through bolts to achieve the movement of the carriage 32.

[0054] As Figure 2 shown, as an implementation manner, the magnetic field adjusting device further includes a tray 33. The tray 33 is used to support the accommodating body 1. The tray 33 is connected to the connecting pipe 7. When the carriage 32 is driven to move, the tray 33 also moves synchronously with the accommodating body 1 to achieve the conveying of the accommodating body 1.

[0055] Optionally, the tray 33 is provided with holes, and the connecting pipe 7 is also provided with holes. When the tray 33 is placed on the connecting pipe 7, a pin can be inserted to prevent the accommodating body 1 from shaking. In addition, by inserting the pin, it is also convenient for the tray 33 in the constant temperature furnace 5 to be separated from the connecting pipe 7.

[0056] As Figure 2 shown, optionally, a vertical section 331 and a folded edge 332 are provided below the tray 33. Correspondingly, a fixing frame is installed in the constant temperature furnace 5. The fixing frame includes two stop portions 6. The height of the stop portion 6 is slightly higher than the height of the folded edge 332. In this way, when the tray 33 is conveyed into the constant temperature furnace 5, it is located below the stop portion 6, and the stop portion 6 can play a limiting role on the tray 33 in the horizontal direction.

[0057] Optionally, the height of the guide post 3 is higher than the height of the vertical section 331, so as to avoid interference between the folded edge 332 and the support seat 22.

[0058] Optionally, the magnetic field adjusting device may further include a lifting vehicle. The support seat 22 is arranged on the lifting vehicle and adjusted to the corresponding height through the lifting vehicle. Then, the accommodating body 1 is conveyed into the constant temperature furnace 5 through the conveying mechanism. When the tray 33 is placed at the set position, the pin is pulled out from the tray 33. At this time, the lifting vehicle descends slightly to separate the connecting pipe 7 from the tray 33, and then the connecting pipe 7 is retracted, and the switch door of the constant temperature furnace 5 is closed, and different temperature environments are provided for the magnetic material to be detected in the accommodating body 1 to detect the use environment of the magnetic material to be detected.
