Description

Technical Field

[0002] A magnetic lens can converge magnetic flux lines, thereby increasing the magnetic field strength at a specific location, similar to the effect of an optical lens on light. The convergence effect of a magnetic lens on a magnetic field requires measuring the magnetic field strength. In the prior art, the induced electromotive force generated by a Hall element in the magnetic field is often used to determine the strength of the magnetic field to achieve measurement purposes. Because the magnetic field is distributed everywhere on one side of the lens when the magnetic lens converges the magnetic field, it is necessary to measure multiple locations and identify the location with the strongest magnetic field distribution to detect the point of convergence of the magnetic field by the magnetic lens. The prior art generally lacks such equipment to cooperate with this process and enable Hall element detection at various locations, making the detection process difficult and complex.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0023] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing embodiments of the present invention, cross-sectional views of device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0024] Reference Figure 1 The present invention provides a magnetic lens magnetic field measuring device, which comprises a reference position and a detection head 1. The detection head 1 is used to detect the magnetic field strength. Specifically, the detection head 1 can be a Hall element. Regarding the overall layout of the present invention, specifically:

[0025] The reference position is used for directional placement of the magnetic lens;

[0026] The reference position has a measuring side and a magnetic emitting side, and the detection head 1 is configured to maintain a relative linear movement arrangement between the measuring side and the reference position, and the magnetic emitting side is used to provide a magnetic field source;

[0027] Based on the above, the measurement side can be assumed to have a magnetic axis. When the magnetic lens is placed, the magnetic axis points to the center point of the magnetic lens. When the magnetic emitting side provides a magnetic field, the direction of the magnetic field is consistent with the extension direction of the magnetic axis. After the magnetic field passes through the magnetic lens, it converges on the measurement side. The detection head 1 moves on the magnetic axis to measure the magnetic field strength at various locations to find the magnetic convergence point. When the utility model measures the magnetic field convergence point of the magnetic lens, the process is simple and can effectively improve the measurement efficiency compared to the existing technology. The above is a basic introduction to the utility model. The specific structure of the utility model will be described below through examples, as follows:

[0028] Reference Figure 2 and Figure 3 In an embodiment of the present invention, the reference position includes a support portion 2, which is used to carry the magnetic lens. The magnetic emission side and the measuring side are respectively located on the upper and lower sides of the support portion 2. For the movement of the detection head 1, specifically, a guide portion 4 is fixedly connected to the support portion 2, and a sliding portion 5 is slidably provided on the guide portion 4. The detection head 1 is connected to the sliding portion 5, and the movement process of the detection head 1 is realized by sliding the sliding portion 5.

[0029] Further, refer to Figure 2 The support portion 2 is provided with a placement area 3 for accommodating the magnetic lens. The placement area 3 makes the placement process of the magnetic lens more stable and facilitates the position determination during the placement process of the magnetic lens.

[0030] Furthermore, the utility model also includes a driving element 6, and the sliding part 5 can be moved by the driving element 6. A signal connection relationship is established between the driving element 6 and the detection head 1. Specifically, after the driving element 6 drives the sliding part 5 to move the entire path, the detection head 1 has obtained the maximum value of the magnetic field strength on the entire path, that is, the peak value. When the driving element 6 drives the sliding part to move again, the detection head 1 again detects that the current magnetic field strength is equal to the peak value, then this is the convergence point. At this time, the driving element 6 stops driving and keeps the detection head 1 at the current position, thereby determining the magnetic convergence point. The entire signal linkage process can be coordinated with a controller, such as using a computer or a separately configured single-chip microcomputer unit for control.

[0031] Further, refer to Figure 3 The driving element 6 includes a rotating rod 601 rotatably arranged on the guide part 4, which is threadedly engaged with the sliding part 5. The driving element 6 also includes a driving motor 602, which is in transmission cooperation with the rotating rod 601. A signal connection is established between the driving motor 602 and the detection head 1. When the driving motor 602 drives the rotating rod 601 to rotate, the sliding process of the sliding part 5 can be realized through thread cooperation. The thread cooperation can also play a role in position locking. When the driving motor 602 stops working, the position of the sliding part 5 is automatically locked.

[0032] Further, refer to Figure 2 and Figure 3 For providing a magnetic field, the present invention further includes an electromagnetic element 7, which can be an electromagnet. The electromagnetic element 7 is fixedly arranged on one side of the support portion 2, so as to facilitate the magnetic field required for measurement.

[0033] It will be appreciated that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will, for those of ordinary skill having the benefit of this disclosure, be a routine undertaking of design, fabrication, and production without undue experimentation.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
