Description
Technical Field
[0001] The utility model belongs to the technical field of magnetic detection, and in particular relates to a magnetic detection device. Background Art
[0002] Magnetism refers to the phenomenon that a substance is affected by magnetic force in an uneven magnetic field. In the same uneven magnetic field environment, we can evaluate the strength of its magnetism by measuring the direction and intensity of the magnetic force per unit mass of the substance. For the produced magnetic coils, we need to conduct magnetic testing to determine whether they meet the quality standards.
[0003] For different detection requirements, the detection position on the coil will also be different. For example, if the overall magnetic capacity of the coil needs to be detected, the detection probe needs to be placed in the center area of the coil; and if the magnetic field strength or distribution at the edge of the coil needs to be evaluated, the edge of the coil should be selected for detection. As for the existing detection devices on the market, simply setting a magnetometer and constantly adjusting it to the center area of the coil to be detected can complete the detection of the overall magnetic capacity of the coil, but the above detection device cannot meet the detection of the edge of the coil.

[0021] The utility model accurately captures the edge range of the coil to be detected by arranging three magnetometers 14 on the circumference, thereby realizing accurate detection; the magnetometer 14 is also installed on the adjusting inclined plate 13, and the linkage between the hinged rod 17, the push plate 16 and the supporting tube 7 drives the straight plate 15 on the adjusting inclined plate 13 to rotate, thereby driving the adjusting inclined plate 13 to rotate on the rotating rod 12, and the adjusting inclined plate 13 rotates outward, which drives the magnetometer 14 to move outward synchronously, thereby realizing the expansion of the detection range, and being suitable for the detection of coils of various specifications and sizes.
[0022] Example 2
[0023] like Figures 1 to 5 The magnetic detection device for the edge of a coil shown in the figure includes a main unit 1, and a control box 2 is connected to the front side of the main unit 1. The control box 2 is used to control all electrically connected components in the device, and is used to drive the entire device to operate to achieve magnetic detection of the edge of the coil. The bottom of the control box 2 is connected to a suction cup 3 through a suction pipe, and then the suction cup 3 operates to drive the suction pipe to fill in air to complete the adsorption of the coil to be detected below, that is, the operator can move the coil to be detected below the suction cup 3. After the suction cup 3 detects the coil to be detected below, it automatically operates to complete the adsorption of the coil to be detected, so that the bottom of the coil to be detected is completely open to cooperate with the detection.
[0024] The front side of the host 1 is provided with a chassis 4, which is hollow, and a push rod 5 is provided at the bottom of the chassis 4. The upper part of the push rod 5 is symmetrically connected with a connecting rod 6, and a support tube 7 is connected between the outer sides of the connecting rod 6, that is, the push rod 5 can be stretched or shortened and the supporting tube 7 can be driven by the connecting rod 6 to move up and down to cooperate with subsequent operations. A plurality of guide rails 8 are provided on the top of the supporting tube 7, and a guide rod 9 is slidably provided inside the guide rail 8. A guide tube 10 is connected between the inner sides of the guide rod 9, that is, the guide tube 10 will be located at the top of the supporting tube 7 at the lower limit of the action of the guide rod 9, and will also move up and down between the guide rails 8 under the driving action of the guide rod 9. A mounting rod 11 is provided on the outer side of the upper part of the guide tube 10 at the horizontal position of each guide rod 9, and the length of the mounting rod 11 is consistent with that of the guide rod 9, and a rotating rod 12 is rotatably connected between the two, and a magnetometer 14 is installed on the rotating rod 12 by setting an adjustment inclined plate 13. The magnetometer 14 is a machine used to detect objects. It mainly determines the magnetic strength of the object through changes in the magnetic field and converts the measurement results into corresponding physical quantities. After the magnetometer 14 is applied to the utility model, the magnetism of the coil can be detected by placing the magnetometer 14 at the edge of the coil.
[0025] It should be noted that, different from the single detection position in the prior art, in this embodiment, the number of guide rails 8, mounting rods 11, and adjusting inclined plates 13 are all set to 3, and the number of magnetometers 14 installed on the adjusting inclined plates 13 is also 3. At the same time, through the positioning of the inner guide cylinder 10, the detection range of the three magnetometers 14 forms a complete circle, which is adapted to the appearance of the coil to be detected to achieve accurate detection; and the increase in the number of magnetometers 14 will also relatively improve the detection efficiency, and the number can be customized according to actual needs.
[0026] Example 3
[0027] like Figures 1 to 5 A magnetic detection device for the edge of a coil is shown, in which three magnetometers 14 are arranged on the outside of the guide tube 10, so that its detection range forms a complete circle, which is adapted to the appearance of the coil to be detected. Then, when the suction cup 3 drives the lower coil to be detected to be adsorbed, the magnetometer 14 can perform magnetic detection on the bottom outer edge of the coil to be detected, and convert the measurement results into corresponding physical quantities and display them on the display screen of the control box 2, which is used to screen defective products. However, for coils of different sizes and specifications, the edge distance of the coil will be inconsistent, and at this time, the position of the magnetometer 14 will no longer be accurately at the edge of the coil, and the coil cannot be accurately magnetically detected. Then, this embodiment is provided with a circumferential adjustment of the magnetometer 14, so that it can move outward at the same time, and adjust to a position parallel to its edge according to the size and diameter of different coils, so as to achieve accurate detection.
[0028] The specific settings are:
[0029] The inclined part of the adjustment bevel plate 13 is located on the outside, and the magnetometer 14 is installed on the outside of the adjustment bevel plate 13. Therefore, when the adjustment bevel plate 13 is rotated, the magnetometer 14 can be swung outward to expand the detection range of the magnetometer 14 and adapt to the edge detection of coils of different specifications and sizes; therefore, a straight plate 15 is extended on the inner side of the adjustment bevel plate 13, and a push plate 16 is provided at the bottom of the straight plate 15. Then, the adjustment of the adjustment bevel plate 13 can be indirectly achieved by pushing the push plate 16, for example: pushing the push plate 16 to move inward, and then the straight plate 15 can be pushed inward, the adjustment bevel plate 13 rotates on the rotating rod 12 and swings outward, thereby driving the magnetometer 14 also placed on it to swing outward, and the three magnetometers 14 swing outward at the same time to complete the synchronous expansion of the detection range; conversely, the push plate 16 moving outward can drive the magnetometer 14 to narrow the detection range.
[0030] Example 4
[0031] On the basis of Example 3, the guide cylinder 10 needs to be fixedly installed below the coil to be detected, and the detection result obtained will be more accurate. Then, mounting seats 18 are arranged at the four corners of the top of the chassis 4, and support plates 19 are connected between the tops of the mounting seats 18. The support plates 19 are used to fix the guide cylinder 10. The three mounting rods 11 arranged on the outer side of the top of the guide cylinder 10 extend outwardly with limit rods 20. The limit rods 20 are connected to the support plates 19 to complete the limit fixation of the guide cylinder 10. The guide cylinder 10 is fixed on the support plates 19. At this time, the horizontal positions of the mounting rods 11, rotating rods 12, adjusting inclined plates 13, magnetometers 14 and guide rods 9 on the guide cylinder 10 are all fixed, and the relative sliding arrangement between the guide rods 9 and the guide rails 8 can increase the stability of the push rod 5 when pushing the support cylinder 7.
[0032] Next, the adjustment of the adjustment inclined plate 13 can be linked with the push rod 5. It is known that the operation of the push rod 5 will drive the support tube 7 to move up and down. When a hinged rod 17 is hingedly connected between the support tube 7 and the push rod 5, when the support tube 7 moves downward, the push plate 16 and the straight plate 15 can be driven inward by the hinged rod 17, thereby driving the side of the adjustment inclined plate 13 where the magnetometer 14 is installed to rotate outward, thereby achieving the effect of expanding the detection range and adapting to the edge detection of coils of different specifications.
[0033] Example 5
[0034] like Figures 1 to 5A magnetic detection device for the edge of a coil is shown. Since magnetic detection is also closely related to its detection distance, if the magnetometer 14 and the coil can be placed in the optimal detection range, the detection result will be more accurate. Therefore, a cylinder 21 is also connected between the control box 2 and the suction cup 3. The cylinder 21 is installed at the bottom of the control box 2, and the suction cup 3 is connected to the telescopic rod end of the cylinder 21. The suction cup 3 can be driven to move vertically up and down under the driving action of the cylinder 21, and then the coil to be detected adsorbed under the suction cup 3 can be driven to move up and down, thereby completing the adjustment of the vertical distance between the coil and the magnetometer 14, and cooperating with more accurate magnetism.
