Description

Technical Field

[0001] This utility model relates to the field of banknote verification sensor technology, and in particular to a matrix magnetic sensor assembly with an integrated riveted iron core. Background Technology

[0002] The magnetic head for banknote verification is a crucial component in banknote detectors and other equipment used to detect the magnetic characteristics of banknotes. Its working principle involves detecting magnetic ink and converting and analyzing electrical signals. For example, during the printing process, banknotes are printed with magnetic ink to create specific patterns. The magnetic characteristics of these patterns, such as magnetic field strength and magnetic distribution, follow certain patterns. The magnetic head can sense the magnetic signals on the banknote. When a banknote passes near the magnetic head, it can determine its authenticity based on pre-set magnetic characteristic parameters. With continuous technological advancements, banknote verification technology is constantly evolving. In addition to acquiring magnetic signals through the magnetic head, strong magnets are also installed on both sides of the magnetic head to assist in identification.

In the existing technology, when assembling the magnetic head, several magnetic heads are first arranged and laser welded, and then the assembled magnetic head group is installed into the housing. In the existing assembly method, errors are easily generated during the arrangement and welding of magnetic heads, resulting in misalignment between magnetic heads, which requires repeated adjustments, resulting in low production efficiency and low pass rate.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0033] In the existing technology, the structure of the banknote verification magnetic head can refer to the magnetic head structure disclosed in CN103886669A. In the existing technology, when assembling the magnetic head, several magnetic heads are first arranged and laser welded, and then the assembled magnetic head group is installed into the housing. In the existing assembly method, errors are easily generated during the arrangement and welding of magnetic heads, resulting in misalignment between magnetic heads, which requires repeated adjustments, resulting in low production efficiency and low pass rate.

[0034] To address the aforementioned problems in the existing technology, this utility model provides a matrix magnetic sensor assembly with an integrated riveted iron core, such as... Figure 1 As shown, the matrix magnetic sensor assembly with an integrated riveted iron core includes: a housing 100; a magnetic core assembly 200, which is fitted into the inner cavity of the housing 100. The magnetic core assembly 200 includes a plurality of magnetic heads 211 arranged in a row, and a connecting plate 212 symmetrically arranged on both sides of the plurality of magnetic heads 211. The connecting plate 212 is provided with a plurality of mounting grooves 215 on one side corresponding to the plurality of magnetic heads 211. The magnetic heads 211 are fitted and fixedly connected to the connecting plate 212.

[0035] This invention provides connecting plates 212 on both sides of the magnetic head 211. Each connecting plate 212 has a plurality of mounting grooves 215 on one side corresponding to a plurality of magnetic heads 211. The magnetic heads 211 are clamped and limited by the two connecting plates 212 to form a row, thereby facilitating assembly with the housing 100. This invention restricts the assembly position of different magnetic heads 211 by the connecting plates 212, strengthens the combined strength of the magnetic heads 211, and avoids misalignment between the magnetic heads 211. The assembly process does not require welding, which can effectively improve production efficiency and pass rate.

[0036] In this embodiment, as Figure 1 As shown, the main body of the matrix magnetic sensor assembly with an integrated riveted iron core consists of a housing 100 and a magnetic core assembly 200. The housing 100 is made of metal and serves to shield the magnetic field. The magnetic core assembly 200 specifically consists of several magnetic heads 211 and two connecting plates 212 disposed on both sides of the magnetic heads 211. To correspond to the magnetic signal distribution of items such as banknotes in the prior art, the magnetic heads 211 are connected in a row to acquire magnetic signals from different parts of the banknotes or other items. Two connecting plates 212 are provided, symmetrically disposed on both sides of the magnetic heads 211, and both connecting plates 212 are connected to the magnetic heads. 211 Fixed connection. In actual setup, several mounting slots 215 are provided on one side of the connecting plate 212 corresponding to several magnetic heads 211. The shape of the mounting slots 215 is adapted to the shape of the side of the magnetic head 211. In actual assembly, the magnetic head 211 is fitted and fixedly connected to the connecting plate 212. By providing several mounting slots 215 with corresponding positions on the connecting plate 212, on the one hand, several magnetic heads 211 are connected in a corresponding and flush manner to prevent the magnetic heads 211 from forming a misalignment during subsequent assembly. On the other hand, the magnetic head 211 group formed in this way forms a whole, which can be easily installed in the inner cavity of the housing 100, simplifying the assembly process and reducing the assembly difficulty.

[0037] Furthermore, such as Figure 1As shown, to achieve a fixed connection between the connecting plate 212 and the plurality of magnetic heads 211, in this embodiment, screw holes 213 are provided on the connecting plate 212 at positions corresponding to the magnetic heads 211. Furthermore, the connecting plate 212 also includes a plurality of screws, which pass through the screw holes 213 and are fixedly connected to the magnetic heads 211, thus forming a fixed connection between the connecting plate 212 and the plurality of magnetic heads 211. Simultaneously, during this assembly process, the screws, screw holes 213, and corresponding structures on the magnetic heads 211 correspond, further limiting the plurality of magnetic heads 211 beyond the limitation imposed by the mounting groove 215, thereby maintaining them on the same mounting surface. This ensures the consistency of the assembly dimensions of the magnetic heads 211 and avoids misalignment of the magnetic heads 211, which could affect the accuracy of acquiring magnetic signals from banknotes and other items. In addition, the screw-connected installation method between the connecting plate 212 and the magnetic heads 211 further improves the assembly stability of the magnetic heads 211 and the connecting plate 212, preventing the magnetic heads 211 from loosening or falling off during use.

[0038] In another possible embodiment of this utility model, such as Figure 1 As shown, a plurality of support portions 214 protrude from the side of the connecting plate 212 opposite to the magnetic head 211. These support portions 214 are evenly arranged at predetermined intervals. When the support portions 214 are actually installed, they are positioned to avoid interfering with the installation and use of the screw holes 213 and screws. When the magnetic core assembly 200 is fitted into the inner cavity of the housing 100, these support portions 214 abut against the corresponding sidewalls inside the housing 100, facilitating assembly and further enhancing the stability and robustness of the first magnetic core module 210 within the housing 100. Furthermore, the support portions 214 help to distribute and bear the forces that the magnetic core assembly 200 may experience during use, reducing the risk of damage to the magnetic core assembly 200 due to uneven stress.

[0039] Based on the above embodiments, in one specific implementation of this utility model, such as Figure 1As shown, in order to ensure accurate assembly of the housing 100 and the magnetic core assembly 200, in this embodiment, the housing 100 also includes a plurality of assembly grooves 120 stamped on opposite side walls. The plurality of assembly grooves 120 protrude toward the inner cavity of the housing 100. Stamping is a processing method that uses a die (mold) to separate or deform metal sheet. During the stamping process, the material is usually in an elastic or elastoplastic state. With the help of the external force applied by the press, the sheet metal undergoes a corresponding shape change, thereby obtaining a part with a certain shape, size and performance. In this embodiment, the assembly groove 120 formed by stamping does not affect the integrity of the housing 100, that is, there is no opening structure on the opposite side walls of the housing 100, thereby avoiding phenomena such as magnetic leakage and noise on both sides of the housing 100. On the other hand, the assembly groove 120 formed by stamping protrudes from the inner cavity of the housing 100, which can achieve engagement with the magnetic core assembly 200. This not only achieves the effect of positioning and installing the magnetic core assembly 200, but also fixes the magnetic core assembly 200 inside the housing 100, which can effectively prevent the magnetic head 211 in the magnetic core assembly 200 from displacing and retracting during use.

[0040] Specifically, in one embodiment, the shape of the support 214 can be pre-processed so that the support 214 can fit with the protruding parts of the mounting grooves 120 on both sides of the housing 100. That is, the support 214 and the assembly grooves 120 formed by stamping are installed to a predetermined position by the elastic deformation of the material, so that the protruding parts of the assembly grooves 120 are engaged with the fitting structure of the support 214, forming a fixed connection. The advantage of this embodiment is that it facilitates the disassembly and maintenance of the magnetic core assembly 200 in the later stage.

[0041] In another possible implementation, such as Figure 3 and Figure 4As shown, to more firmly fix the magnetic core assembly 200 inside the housing 100, in this embodiment, the support portion 214 can be positioned to avoid the assembly groove 120. Simultaneously, an encapsulation layer 400 is provided on the outer side of the magnetic core assembly 200. The encapsulation layer 400 can specifically be made of resin. After the magnetic core assembly 200 is pushed to a predetermined position inside the housing 100, the encapsulation layer 400 can be injected into the area between adjacent support portions 214, so that the encapsulation layer 400 wraps around the magnetic core assembly 200. After the encapsulation layer 400 cures, it forms a wrapping around the magnetic core assembly 200 and the protruding portion of the assembly groove 120, and the encapsulation layer 400 engages with the protruding structure of the assembly groove 120, thereby further enhancing the fixing effect of the magnetic core assembly 200 inside the housing 100. This design not only improves the stability of the magnetic core assembly 200 but also helps prevent magnetic leakage and noise generation, thereby extending the service life of the magnetic head 211. In practical applications, this matrix magnetic sensor assembly, which prevents magnetic leakage, can more accurately acquire the magnetic signals of banknotes and other items, improving the accuracy and efficiency of banknote verification.

[0042] In another possible embodiment of this utility model, such as Figure 1 As shown, to avoid magnetic interference between adjacent magnetic heads 211, a baffle 216 can be provided between adjacent magnetic heads 211 in this embodiment. Simultaneously, to improve the torsional resistance of the magnetic core assembly 200, a slot 217 is provided on the connecting plate 212 corresponding to the position of the baffle 216. The side of the baffle 216 is fitted into the slot 217, thereby limiting the magnetic head 211 through the cooperation of the connecting plate 212 and the baffle 216, improving the stability of the magnetic head 211 installation, reducing interference between adjacent magnetic heads 211, and ensuring the performance of the magnetic sensor assembly. Furthermore, the design of the slot 217 simplifies the installation of the baffle 216 and improves assembly efficiency.

[0043] In another possible embodiment of this utility model, such as Figure 1 and Figure 2As shown, in actual setup, the large number of magnetic heads 211 in the core assembly 200 results in a relatively long core assembly 200. To improve assembly comfort and efficiency, in this embodiment, the core assembly 200 can be configured as a symmetrically arranged first core module 210 and second core module 220. Both the first core module 210 and the second core module 220 include the same number of magnetic heads 211 and connecting plates 212 disposed on both sides of the magnetic heads 211, forming two sets of magnetic heads 211. In actual assembly, the first core module 210 and the second core module 220 are separately fitted into the housing 100 to facilitate the assembly and disassembly of the core assembly 200. Furthermore, the separate arrangement of the first core module 210 and the second core module 220 also facilitates quality inspection and maintenance of the core assembly 200 during manufacturing, improving production efficiency.

[0044] In a preferred embodiment of this utility model, after repeated experiments by the designers, when the number of magnetic heads 211 in the first magnetic core module 210 and the second magnetic core module 220 is set to 8 respectively, the front-to-back and high-to-low misalignment consistency is optimal, the adjustment time is short, the production efficiency is high, and the quality is also very stable, which greatly improves the production efficiency and reduces the production cost.

[0045] When the magnetic core assembly 200 is configured as a first magnetic core module 210 and a second magnetic core module 220, in order to limit the assembly position of the first magnetic core module 210 and the second magnetic core module 220 inside the housing 100, such as Figure 2 As shown, a partition 300 is also provided in the inner cavity of the housing 100. The partition 300 is located in the middle of the length direction of the housing 100 and is perpendicular to the length direction of the housing 100. The partition 300 is made of the same metal material as the baffle 216 and the housing 100. It is fixedly connected to the housing 100 by laser welding, dividing the inner cavity of the housing 100 into two symmetrical chambers. In specific installation, the first magnetic core module 210 is fitted into the inner cavity of the housing 100 on one side of the partition 300, and the second magnetic core module 220 is fitted into the inner cavity of the housing 100 on the other side of the partition 300. Through this arrangement, the inner cavity of the housing 100 is partitioned, and the space distribution in the inner cavity of the housing 100 is refined. This ensures that the assembly of the magnetic core assembly 200 in the housing 100 is more accurate and stable. At the same time, it avoids the shaking or displacement that may occur during the use of the magnetic core assembly 200, so as to prevent magnetic leakage and magnetic core sinking. In addition, the design of the partition 300 facilitates the modular installation and disassembly of the magnetic core assembly 200, improving the convenience of maintenance and replacement.

[0046] Furthermore, such as Figure 1As shown, in order to further improve the installation efficiency and installation stability of the first magnetic core module 210 and the second magnetic core module 220, guide plates 230 are respectively provided on the first magnetic core module 210 and the second magnetic core module 220 at positions corresponding to both ends of the housing 100. The guide plates 230 are set along a predetermined arc and are made of elastic material, specifically, they can be elastic metal materials, such as iron. The guide plate 230 is fixedly connected to the connecting plate 212. Since the guide plate 230 has a certain curvature, the ends of the first magnetic core module 210 and the second magnetic core module 220 form smooth arc surfaces. When the first magnetic core module 210 and the second magnetic core module 220 are assembled into the housing 100, they can play a guiding role in the installation. At the same time, the arc surface of the guide plate 230 also plays an elastic role. When the first magnetic core module 210 and the second magnetic core module 220 are installed into the housing 100, the inner wall of the housing 100 compresses the guide plate 230, causing the guide plate 230 to undergo slight elastic deformation and exert pressure on the inner wall of the housing 100. This elastic pressure limits the first magnetic core module 210 and the second magnetic core module 220, and plays a certain role in buffering and dispersing stress when the housing 100 is subjected to impacts, which can effectively prevent the magnetic core assembly 200200 from being damaged due to excessive force.

[0047] The aforementioned guide plate 230 further simplifies the installation process of the magnetic core assembly 200 and improves installation efficiency. During actual assembly, the magnetic core assembly 200 is simply pushed into the housing 100 along the curvature of the guide plate 230, and the guide plate 230 guides the magnetic core assembly 200 to accurately and quickly reach the predetermined position, eliminating the need for cumbersome adjustments and positioning operations. Furthermore, the fixed connection between the guide plate 230 and the connecting plate 212 enhances the overall structural strength of the magnetic core assembly 200, making it more stable and reliable during use.

[0048] In the above embodiments, such as Figure 1 As shown, one side of the housing 100 is open for mounting the magnetic core assembly 200. The other side opposite the open side of the housing 100 is defined as the top plate in this embodiment. A clearance groove 110 is provided on the top plate to expose the magnetic head 211 in the magnetic core assembly 200. After assembly, when the magnetic core assembly 200 is fitted into the inner cavity of the housing 100, several magnetic heads 211 are fitted into the clearance groove 110 to be able to correspond with items that need to be verified, such as banknotes, in actual use, so as to obtain magnetic signals.

[0049] Based on the above embodiments, the actual assembly process of the matrix magnetic sensor assembly with an integrated riveted iron core of this utility model is as follows:

[0050] First, such as Figure 1As shown, several magnetic heads 211 and connecting plates 212 are assembled to form a first magnetic core module 210 and a second magnetic core module 220.

[0051] like Figure 2 As shown, the first magnetic core module 210 and the second magnetic core module 220 are respectively fitted into the inner cavities of the housing 100 on both sides of the partition 300, ensuring that the magnetic head 211 corresponds to the clearance groove 110 on the top plate of the housing 100. During installation, the first magnetic core module 210 and the second magnetic core module 220 can also be pushed along the arc direction of the guide plate 230 into the two inner cavities of the partition 300 within the housing 100.

[0052] Subsequently, as Figure 4 As shown, an encapsulation layer 400 is injected into the space between adjacent support portions 214. After the encapsulation layer 400 cures, it wraps around the magnetic core module and forms a firm engagement with the protruding structure of the assembly groove 120 towards the inside of the housing 100, thereby further securing the magnetic core assembly 200. Finally, the assembly 200 is checked to ensure it is securely installed and that the encapsulation layer 400 is completely wrapped, ensuring the assembly quality and performance of the leakage-proof matrix magnetic sensor assembly.

[0053] In summary, this utility model provides a matrix magnetic sensor assembly with an integrated riveted iron core. The assembly includes a housing and a magnetic core assembly, which is fitted into the inner cavity of the housing. The magnetic core assembly includes a plurality of magnetic heads arranged in a row and connecting plates symmetrically arranged on both sides of the magnetic heads. Each connecting plate has a plurality of mounting grooves on one side corresponding to the magnetic heads, and the magnetic heads are fitted and fixedly connected to the connecting plates. This utility model provides connecting plates on both sides of the magnetic heads, with mounting grooves on one side corresponding to the magnetic heads. The two connecting plates clamp and limit the magnetic heads to form a row, facilitating assembly with the housing. This utility model restricts the assembly positions of different magnetic heads through the connecting plates, strengthening the combined strength of the magnetic heads and preventing misalignment between them. The assembly process requires no welding, effectively improving production efficiency and yield.
