Description

Technical Field

[0001] The utility model relates to the technical field of magnetic induction intensity detection, in particular to a planar bipolar magnetic ring magnetic flux density detection device. Background Art

[0002] Magnetic induction intensity detection devices are widely used in industry, scientific research, medicine, and daily life. Magnetic induction intensity detection can be used to evaluate the performance of magnetic separation equipment, analyze the magnetic properties of materials, and monitor environmental magnetic fields, thereby facilitating magnetic field control and ensuring the normal operation of equipment.

[0003] Planar bipolar magnetic rings are a special type of magnetic ring structure, consisting of two or more concentric circular magnetic rings. Planar bipolar magnetic rings are widely used in magnetic levitation technology, electronic countermeasures and radar systems, medical equipment, automated production lines, and electronic products.

[0004] The existing method for detecting the magnetic flux density of a planar bipolar magnetic ring is to use a Gaussmeter to measure a local point on the magnetic ring. However, different operators cannot place the probe in exactly the same way, and the contact method and pressure between the probe and the magnetic ring surface are also different. Therefore, the measured data are also different, with poor reproducibility and non-objective results. Especially when the magnetic ring is composed of splicing, the magnetic flux density in the local area is different from that of the overall situation. There may also be a paradoxical situation where the measurement result is qualified but the overall magnet's adsorption force is low. The measurement result has no strict correlation with the adsorption force index required for the application. Utility Model Content

They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Unless otherwise specified, "plurality" means two or more.

[0023] Unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components.

[0024] like Figure 1 As shown, a planar bipolar magnetic ring magnetic flux density detection device includes a detector body 1, electrically connected to a first magnetic flux density sensor 2 and a second magnetic flux density sensor 3. The magnetic ring is rotatably placed within the detector body 1. In this embodiment, the first magnetic flux density sensor 2 and the second magnetic flux density sensor 3 are both Hall effect sensors, corresponding to the inner and outer sides of the magnetic ring, respectively. The detector body 1 is provided with a data processor 11 and a display assembly 13.

[0025] The magnetic flux density detection device of this embodiment connects the signal generated by the Hall sensor to the data processor 11 through the PCB circuit. After the signal undergoes A / D conversion and other calculation processing, the display component 13 displays information such as the polarity, surface magnetic flux density, and temperature of the corresponding positions of the inner and outer rings of the magnetic ring.

[0026] The test platform of this embodiment is provided with a mounting slot for accommodating the magnetic ring. The mounting slot is rotatably mounted on the test platform and connected to a motor drive system. The motor drive system can drive the mounting slot to rotate at a specified speed to achieve synchronous measurement of the magnetic flux density inside and outside the magnetic ring.

[0027] Through this solution, users can control the rotation speed of the mounting slot. At the same time, the motor drive system can also provide a stable rotation speed and torque for the magnetic ring, reducing the magnetic flux density measurement error caused by rotation speed fluctuations or uneven torque, thereby improving the accuracy and reliability of the overall magnetic ring measurement.

[0028] The mounting slot of this embodiment can be enlarged to accommodate most magnetic rings. Several fixing holes, each spaced at varying distances from its center, are also provided on the surface of the slot, along with fixtures that fit within the holes. To secure the magnetic ring, the fixtures are secured to the inner and outer sides of the ring and then tightened between the fixtures. This solution facilitates testing the magnetic flux density of planar bipolar magnetic rings of varying sizes.

[0029] In this embodiment, the data processor 11 is provided with a USB interface 12. The first magnetic flux density sensor 2 and the second magnetic flux density sensor are electrically connected to the data processor 11, and the data processor 11 transmits data via the USB interface 12. Through the above solution, the magnetic flux density detection device can be connected to a variety of devices and systems via the USB interface 12, with high versatility and compatibility, and is more flexible, efficient, and reliable in practical applications.

[0030] The embodiments described above are only preferred implementation methods of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the scope of protection of the present invention.
