Description

Technical Field

[0001] This utility model relates to the field of electromagnetic coil technology, specifically to a magnetic collecting coil for enhancing magnetic fields and its Hall effect detection device. Background Technology

[0002] A Hall element is a magnetic sensor based on the Hall effect, capable of detecting magnetic fields and their changes. It can be used in various magnetic field-related applications, converting measured quantities such as current, magnetic field, displacement, angle, rotational speed, and pressure into electrical signals. For example, an existing Hall plate includes a printed circuit board and multiple Hall elements arranged side-by-side on the printed circuit board. Each Hall element is a ring structure with a perforation in the center. The printed circuit board has corresponding through holes that communicate with the perforation. When current flows through the through holes in the Hall element, the Hall element can detect the corresponding magnetic field and output a corresponding electrical signal. Hall elements need to be tested during production.

[0003] An existing patent (publication number: CN110764039A) discloses an integrated Hall effect device four-station co-testing base. When in use, the device forms a complete Hall effect gaussmeter connection with the circuit detection board and the Hall effect gaussmeter instrument to detect the Gauss value of the magnetic field output by the electromagnet. This allows for convenient and quick screening of defective Hall effect devices. However, the electromagnet generates a magnetic field by energizing the coil. When there are too many coils, a lot of heat is generated after the coils are energized, resulting in excessive power loss. This not only affects the magnetic field strength and reduces the magnetic field Gauss value, but may also damage the coil in severe cases. Therefore, we provide a magnetic field enhancing coil and its Hall effect device testing equipment. Utility Model Content

[0035] ​The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features in the embodiments can be combined with each other.

[0036] Example 1:

[0037] Based on the concept of this application, combined with Figures 1 to 3 This invention describes an embodiment of a magnetic field-enhancing coil for strengthening a magnetic field. Specifically, the magnetic field-enhancing coil is constructed as an integral structure, comprising four components: a coil winding post 1, a central hole 4, a mounting hole 5, and a magnetic collecting rod 6. In this invention, a magnetic collecting rod 6 is installed inside the coil winding post 1. The magnetic collecting rod 6 provides a stronger magnetic field source, effectively supplementing the magnetic field generated by the coil. This reduces the number of coils required during use, not only preventing excessive heat generation in the coils but also providing a continuous and stable magnetic field strength. Furthermore, the magnetic rod is easier to replace and upgrade than the coil, allowing for easy replacement or upgrades when needed.

[0038] Combination Figures 1-3 As shown, the present invention provides a magnetic field enhancement coil, comprising:

[0039] The coil winding post 1 has a top plate 2 and a bottom plate 3 fixedly connected to its top and bottom ends, respectively. The diameters of the top plate 2 and the bottom plate 3 are equal.

[0040] The center hole 4 is located at the center of the coil winding post 1 and passes through the coil winding post 1.

[0041] Multiple mounting holes 5 are provided inside the coil winding post 1. The number of mounting holes 5 is even, and the multiple mounting holes 5 are distributed in a ring at equal intervals around the central hole 4.

[0042] The magnetic rod 6 is detachably installed in the mounting hole 5.

[0043] According to the technical scheme of the embodiment, the coil winding column 1, the top plate 2 and the bottom plate 3 are all made of aluminum alloy, and the surface of the aluminum alloy is subjected to oxidation treatment. Compared with other metals (such as stainless steel), the aluminum alloy is lighter, which reduces the weight of the entire magnetic collection coil, facilitates installation and use, and has good corrosion resistance and wear resistance, so that the coil winding column 1 is more durable. In addition, the aluminum alloy has good heat conduction performance, which means that the coil can quickly transfer heat to the coil winding column 1, preventing the coil from being affected by the magnetic field strength due to overheating or even being damaged.

[0044] According to the technical scheme of the embodiment, the center hole 4 is provided as a through hole, and the diameter of the center hole 4 is 8-12mm. In actual use, the upper and lower ends of the center hole 4 are connected and installed with the external structure through bolts.

[0045] According to the technical scheme of the embodiment, the outer surface of the coil winding column is wound with a coil. When the coil is powered, a magnetic field is generated in the surrounding space.

[0046] According to the technical scheme of the embodiment, the mounting hole 5 is provided as a through hole, and the upper and lower ends of the through hole are respectively penetrated through the top plate 2 and the bottom plate 3. The mounting hole 5 is mainly used for installing the magnetic collection rod 6, which is convenient to operate. In actual use, the coil is powered to generate a certain strength of magnetic field. However, when the number of coils is too large, a large amount of heat will be generated after the coil is powered, which will cause excessive power loss. Not only will it affect the strength of the magnetic field, but also it will damage the coil. The magnetic field generated by the magnetic collection rod 6 can compensate for the magnetic field generated by the coil to a certain extent, so that the number of coils can be reduced during use. This can not only avoid excessive heat generated by the coil, but also provide a continuous and stable magnetic field strength.

[0047] According to the technical scheme of the embodiment, the magnetic collection rod 6 is provided as a single-layer annular arrangement or a multi-layer annular arrangement. In actual use, the magnetic collection rod 6 can be arranged according to the actual situation. This embodiment does not limit it, but on the basis of the technical scheme of the embodiment, only different arrangements of the magnetic collection rod 6 are used to generate a uniform magnetic field, which still falls within the protection scope of the embodiment.

[0048] Further, in actual use, the cross-sectional shape of the magnetic collection rod 6 can be circular, square or other polygonal shape. This embodiment does not limit it, and it can be selected according to the actual situation. It should be noted that in order to ensure the generation of a uniform magnetic field, the magnetic collection rod 6 is increased or reduced in a symmetrical manner, for example, two magnetic collection rods 6 at symmetrical positions are reduced or increased.

[0049] Further, the magnetic collecting rod 6 is made of neodymium iron boron material, which has higher strength and saturation magnetization compared with many other types of magnetic materials, which means that the magnet made of neodymium iron boron can withstand greater force and can generate a greater magnetic field in a shorter time under the same magnetic field.

[0050] Specifically, in actual use, the coil is mainly energized to generate a certain strength of magnetic field, but when the number of coils is too large, a large amount of heat will be generated after the coil is energized, which will cause excessive power loss, not only affecting the strength of the magnetic field, but also damaging the coil. The magnetic field generated by the magnetic collecting rod 6 can compensate for the magnetic field generated by the coil to some extent, so that the number of coils can be reduced during use, which can not only avoid excessive heat generated by the coil, but also provide a continuous and stable magnetic field strength.

[0051] The magnetic collecting coil for enhancing the magnetic field provided by the utility model will be further described below in combination with the drawings and embodiments.

[0054] The center hole 4 is arranged at the center position of the coil winding column 1, and the center hole 4 penetrates the coil winding column 1;

[0055] A plurality of mounting holes 5 are arranged inside the coil winding column 1, the mounting holes 5 are arranged as an even number, and the plurality of mounting holes 5 are arranged in a ring shape around the center hole 4 at equal intervals;

[0056] The magnetic collecting rod 6 is detachably installed in the mounting hole 5.

[0057] Embodiment two:

[0058] As shown in Figure 4 The fundamental difference between embodiment two and embodiment one is:

[0059] The mounting hole 5 is arranged as a blind hole, the top end of the blind hole is arranged as an opening penetrating the top plate 2, and the bottom end of the blind hole does not penetrate the bottom plate 3, so that when the magnetic collecting rod 6 is installed, it can be directly installed into the mounting hole 5, without worrying about the magnetic collecting rod 6 falling off, and the operation is more simple.

[0060] Embodiment three:

[0061] The fundamental difference between embodiment three and embodiment one is:

[0062] The central hole 4 is in the center of the magnetic collecting coil, so that the uniformity of the magnetic field can be ensured, and the magnetic collecting rod 6 does not need to be arranged symmetrically compared with the first embodiment, and cost can be saved to a certain extent.

[0063] Embodiment four:
