[0022] The structure of the banknote verification magnetic head can refer to the banknote verification magnetic head disclosed in CN222167658U. The main sensing component of the magnetic head is a central magnetic plate sandwiched between two magnetic cores, and magnetic plates are set on both sides of the central magnetic plate to form a clamping structure to improve anti-interference performance. In the prior art, the magnetic plates on both sides of the central magnetic plate are fixed by welding and then inserted into the preset groove of the wire frame. This installation process has high requirements for the flatness of the clamping structure, and the embedding process is prone to deformation, resulting in low production efficiency and yield.

[0023] To address the aforementioned problems in the existing technology, this utility model provides a sensor assembly structure with a V-shaped central magnetic plate, such as... Figure 1 As shown, the sensor assembly structure with a V-shaped central magnetic plate includes: a wire frame 100, on which an assembly groove 111 is provided; a central magnetic plate 200, which includes an insertion part 210 adapted to the shape of the assembly groove 111; and a clamping plate 300, which is bent to a predetermined angle along the axis of symmetry, and the clamping insertion part 210 is inserted into the assembly groove 111.

[0024] This invention, by bending the clamping plate 300 along the axis of symmetry, clamps the insertion portion 210 of the central magnetic plate 200, forming a V-shaped guide structure. When combined with the assembly groove 111 on the wire frame 100, it can guide the assembly and ensure accurate alignment between the clamping plate 300 and the central magnetic plate 200. This simplifies the assembly process, reduces the requirements for installation technology, effectively prevents deformation of the clamping plate 300, improves production efficiency, and ensures product quality.

[0025] In the above embodiments, such as Figure 1As shown, the main body of the sensor assembly structure with a V-shaped central magnetic plate of this utility model consists of a wire frame 100, a central magnetic plate 200, and a clamping plate 300. The wire frame 100 is provided with an assembly slot 111 for mounting the central magnetic plate 200. The wire frame 100 is made of non-magnetic or non-magnetic materials, such as plastic or rubber, to avoid affecting the magnetic induction of the sensor during use. The central magnetic plate 200 is the main component for reading magnetic characteristic information. In this embodiment, to ensure a stable structure formed by combining the central magnetic plate 200 and the wire frame 100 and preventing shaking due to friction during use... The middle magnetic plate 200 includes an insertion part 210 that matches the shape of the assembly groove 111. During actual installation, the insertion part 210 is inserted into the assembly groove 111. To improve the anti-interference performance of the middle magnetic plate 200, existing technologies weld magnetic plates to both sides of the middle magnetic plate 200. However, existing technologies tend to reduce the flatness of the clamping structure, adversely affecting the assembly process. Therefore, in this application, the clamping plate 300 (made of the same material as the magnetic plates in the prior art) is set as a single piece, and the clamping plate 300 is bent at a predetermined angle along the axis of symmetry to form a clamping structure for the middle magnetic plate 200. Figure 2 As shown, the bending of the clamping plate 300 forms a slope angle, and the V-shaped structure formed by the bending can play a guiding role, thereby facilitating the insertion of the clamping plate 300 into the assembly groove 111.

[0026] The above structural design simplifies the assembly process by eliminating the need for welding and avoids the problem of the clamping structure being difficult to insert into the assembly slot 111 due to flatness issues. It also prevents damage to the clamping plate 300 caused by force during the assembly process.

[0027] In the above embodiments, such as Figure 3 As shown, the width of the clamping plate 300 is adapted to the width of the mating part 210 to ensure that the clamping plate 300 can be tightly clamped onto the mating part 210 of the middle magnetic plate 200 and form a corresponding structure. In addition to achieving anti-interference performance, it can also prevent the mating part 210 and the clamping plate 300 from becoming loose or shaking in the assembly groove 111. At the same time, the height of the folded clamping plate 300 is adapted to the depth of the assembly groove 111. In this way, when the clamping plate 300 clamps the mating part 210 and is inserted into the assembly groove 111, the clamping plate 300 is located in the assembly groove 111, which can avoid interference with the assembly of other functional structures (such as shielding shells) on both sides of the middle magnetic plate 200.

[0028] Furthermore, the corners of the mating portion 210 are set along a predetermined arc. Correspondingly, the clamping plate 300 is chamfered at two sides along the axis of symmetry, i.e., the corners of the folded clamping plate 300 are cut off at a certain angle. When the clamping plate 300 clamps the mating portion 210, as... Figure 3As shown, the arc-shaped corner of the insertion part 210 is exposed at the chamfered corner 310 of the clamping plate 300. When the clamping structure is inserted into the assembly groove 111, the exposed arc-shaped corner on the insertion part 210 can play a guiding role, so that the clamping structure can enter the assembly groove 111 more smoothly, further reducing the assembly difficulty. At the same time, this design also avoids direct collision between the corner of the clamping plate 300 and the edge of the assembly groove 111, reducing the damage that may occur during the assembly process and improving the product yield.

[0029] Furthermore, such as Figure 1 and Figure 2 As shown, the aforementioned middle magnetic plate 200 also includes a contact portion 220 integrally formed with the insertion portion 210. The contact portion 220 protrudes from both sides of the insertion portion 210 along its length. When the middle magnetic plate 200 is inserted into the assembly groove 111, the contact portion 220 engages with the edge of the assembly groove 111, thereby forming a locking limit. This method ensures that the middle magnetic plate 200 is installed in place and facilitates the installation personnel to verify the installation accuracy, improving the error prevention during the installation process of the middle magnetic plate 200. At the same time, in actual use, it also prevents the middle magnetic plate 200 from loosening or falling off due to vibration or impact during use.

[0030] In the above embodiment, the length of the contact portion 220 is adapted to the length of the wire frame 100. The reason for this arrangement is that the banknote verification magnetic head includes multiple wire frames 100 arranged in a row, as well as a central magnetic plate 200 and a clamping plate 300 mounted on the wire frame 100. In actual use, the central magnetic plates 200 on the multiple wire frames 100 are used to sense different parts of the banknote. Therefore, while ensuring that the multiple wire frames 100 are closely arranged, the adjacent central magnetic plates 200 should also correspond closely. Therefore, by setting the length of the contact portion 220 to be the same as the length of the wire frame 100, it is convenient for the assembly personnel to arrange the multiple wire frames 100 in the future and ensure that the multiple central magnetic plates 200 are closely connected.

[0031] In another possible embodiment of this utility model, such as Figure 1 and Figure 4As shown, to facilitate the installation of other functional structures in the sensor, in this embodiment, the wire frame 100 consists of a base frame 110, a bracket 120, and a handle 130. The base frame 110 is located in the middle, and the aforementioned mounting groove 111 is provided on the base frame 110 for installing the middle magnetic plate 200. The two brackets 120 are spaced apart by a predetermined distance and are mirror images of the base frame 110, forming a frame structure with stable support. The two handles 130 are mirror images of the base frame 110 and are fixedly connected to the base frame 110 and the brackets 120. Based on this structural arrangement, the outer side wall of the handle 130 and the opposite side wall of the base frame 110 and the brackets 120 form a groove 131 for installing the coil. This facilitates the installation and fixation of the coil and improves the compactness and aesthetics of the entire structure.

[0032] Specifically, such as Figure 2 As shown, the aforementioned support 130 is hollow inside and extends through the base frame 110 and the bracket 120. The hollow part inside the support 130 is used to install the magnetic core. This structure reduces the weight of the entire structure and improves the installation stability of the magnetic core.

[0033] In actual setup, the mounting slot 111 is aligned with the hollow part inside the support 130, so that the two magnetic cores directly correspond to the insertion part 210 and clamping plate 300 of the inserted middle magnetic plate 200. This ensures the sensitivity and accuracy of the sensor while forming an ingenious corresponding installation structure, enabling the magnetic cores and middle magnetic plates to achieve functional correspondence while also strengthening the structure of the wire frame 100.

[0034] In the above embodiments, the base frame 110, bracket 120 and handle 130 are preferably integrally molded, which simplifies the manufacturing and assembly process, improves production efficiency, and enhances the strength and stability of the entire structure.

[0035] Based on the above embodiments, the actual assembly and fitting process of the sensor assembly structure with the V-shaped magnetic plate in this utility model is as follows: First, such as Figure 2 As shown, the insertion part 210 of the middle magnetic plate 200 is aligned with the clamping plate 300. Since the clamping plate 300 has been bent to a predetermined angle along the axis of symmetry, it forms a V-shaped structure in side view. Then, the insertion part 210 of the middle magnetic plate 200 is placed in the groove formed by bending the clamping plate 300 to form a clamp.

[0036] Next, the clamped middle magnetic plate 200 and clamping plate 300 are aligned with the assembly slot 111 on the wire frame 100. Due to the V-shaped guide structure design, the middle magnetic plate 200 and clamping plate 300 can be accurately guided into the assembly slot 111 without complex adjustments or calibrations. During insertion, the exposed arc-shaped corners on the mating part 210 and the chamfered corners 310 of the clamping plate 300 also serve as guides, allowing the entire clamping structure to enter the assembly slot 111 more smoothly, further reducing the assembly difficulty.

[0037] Once the middle magnetic plate 200 is fully inserted into the assembly slot 111, its contact portion 220 will engage with the edge of the assembly slot 111, forming an engagement limit to ensure that the middle magnetic plate 200 is installed in place and securely. This structural correspondence can be used to check whether the middle magnetic plate 200 and the clamping plate 300 are tightly installed in the assembly slot 111 before finally installing other functional structures.

[0038] Based on the above embodiments, this utility model also provides a banknote verification magnetic head, which includes the sensor assembly structure with a V-shaped central magnetic plate as described in the above embodiments. The sensor assembly structure with a V-shaped central magnetic plate includes: a wire frame with an assembly groove; a central magnetic plate including an insertion portion adapted to the shape of the assembly groove; and a clamping plate bent along an axis of symmetry to a predetermined angle, with the clamping insertion portion inserted into the assembly groove. This utility model, by bending the clamping plate along an axis of symmetry to clamp the insertion portion of the central magnetic plate, forms a V-shaped guiding structure. When combined with the assembly groove on the wire frame, it can guide assembly and ensure accurate alignment between the clamping plate and the central magnetic plate, simplifying the assembly process, reducing installation requirements, effectively preventing clamping plate deformation, improving production efficiency, and ensuring product quality.

[0039] In summary, this utility model provides a sensor assembly structure with a V-shaped central magnetic plate and a banknote verification magnetic head. The sensor assembly structure with a V-shaped central magnetic plate includes: a wire frame with an assembly groove; a central magnetic plate including an insertion portion adapted to the shape of the assembly groove; and a clamping plate bent along an axis of symmetry to a predetermined angle, with the clamping insertion portion inserted into the assembly groove.
