[0031] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0032] like Figures 1 to 6 As shown, a magnetic induction coin recognition device provided by an embodiment of the utility model comprises: a coin recognition component 3 and a bottom plate 1, the upper surface of the bottom plate 1 is detachably connected with a mounting shell 2, and the coin recognition component 3 is arranged on the upper surface of the bottom plate 1; a pusher component 6, one end of one side of the upper surface of the mounting shell 2 is provided with a detection hole, and the pusher component 6 is arranged inside the detection hole; an auxiliary recognition component, the auxiliary recognition component is arranged on the upper surface of the mounting shell 2, and the auxiliary recognition component and the pusher component 6 are arranged correspondingly;

[0033] By designing that the pushing component 6 is arranged inside the detection hole, the pushing component 6 can quickly push out the blind box 5 identified inside the detection hole, thereby facilitating the subsequent placement of the blind box 5 and performing coin identification work.

[0034] Further, the coin identification component 3 includes a display screen 302, a power supply 301, a microprocessor 303, an inductance converter 304 and an electromagnetic sensor 305. The inductance converter 304 is arranged at the lower end inside the detection hole, and the inductance converter 304 is fixedly connected to the bottom plate 1. The inductance converter 304 is electrically connected to the microprocessor 303 and the power supply 301. The microprocessor 303 is electrically connected to the power supply 301 and the display screen 302. A data display hole is opened at one end on the other side of the upper surface of the mounting shell 2, and the display screen 302 is arranged inside the data display hole. A blind box 5 is correspondingly arranged on the upper surface of the inductance converter 304;

[0035] The microprocessor 303 mentioned above can use an STM32 microcontroller as a control module, with a processing frequency of about 72MHz, a maximum memory of 256KB flash memory and a maximum memory of 64KB embedded SRAM, and three packages of LQFP64, LQFP100 and LFBGA100, and different packages maintain pin arrangement consistency;

[0036] The electromagnetic sensor 305 and the inductor converter 304 can be combined into the LDC1614 module with a high-resolution channel to support a larger sensing range, and can still maintain good performance outside the range of twice the coil diameter. The LDC1614 module is used. It is a 4-channel 28-bit inductance digital converter (LDC) for inductive sensing solutions. It can achieve high-performance and reliable inductive sensing at extremely low cost and power consumption;

[0037] Therefore, through the cooperation of the electromagnetic sensor 305, the inductance converter 304 and the microprocessor 303, the denomination of the coins placed in the blind box 5 can be identified through electromagnetic detection without disassembling the blind box 5. At the same time, through the electromagnetic characteristics, the denominations of multiple coins stored in the blind box 5 and the placement order of the multiple denominations of coins can be identified.

[0038] Furthermore, the pushing assembly 6 includes two groups of pushing rods 603, both of which are rotatably installed on the upper surface of the mounting shell 2, and both of which are close to the two sides of the detection hole; the upper surfaces of the two groups of pushing rods 603 are rotatably connected to the supporting shell 601, and both of which are fixedly connected to the upper surface of the mounting shell 2, the upper surfaces of the two groups of supporting shells 601 are rotatably connected to the synchronous wheels 605, and a synchronous belt 606 is sleeved between the two groups of synchronous wheels 605, and a transmission rod 607 is fixedly installed at the bottom center of one group of synchronous wheels 605, and the transmission rod 607 passes through the upper surface of one group of supporting shells 601, and a through hole is opened on the upper surface of one group of supporting shells 601, and the transmission rod 607 is connected to one of the pushing rods The rod 603 is fixedly connected; an installation groove is opened inside the other group of support shells 601, and rotating holes are opened at both ends of the installation groove, a double-axis motor 602 is arranged inside the installation groove, one group of output shafts of the double-axis motor 602 is fixedly connected to the other group of push rods 603, and one end of the other group of output shafts of the double-axis motor 602 is fixedly installed with a gear 604, the gear 604 is rotatably installed on the upper surface of the other group of installation shells 2, and one group of synchronous wheels 605 has multiple groups of tooth grooves opened around the outer side, and the multiple groups of tooth grooves are meshed with the gear 604, the upper surfaces of the two groups of support shells 601 are jointly provided with a protective shell 11, the bottom of the protective shell 11 is provided with a protective groove, and the two groups of synchronous wheels 605 and the gear 604 are correspondingly arranged inside the protective groove;

[0039] Through the design in which multiple sets of teeth are meshed and connected with the gear 604, when the dual-axis motor 602 drives the gear 604 and the other push rod 603 to rotate, one of the push rods 603 can rotate relative to the other push rod 603 through the cooperation of two sets of synchronous wheels 605 and the synchronous belt 606. Therefore, the two sets of push rods 603 cooperate with each other to push the blind box 5 that has been identified inside the detection hole, thereby facilitating the subsequent placement and identification of the blind box 5.

[0040] Furthermore, the auxiliary identification component includes an electric push rod 7, a guide shell 4 is provided on one end of the upper surface of the mounting shell 2 near the detection hole, one end of the electric push rod 7 is fixedly mounted on the lower end of one side of the guide shell 4, a discharge hole is provided at the lower end of the other side of the guide shell 4, and a piston rod of the electric push rod 7 passes through the lower end of one side of the guide shell 4, a through hole is provided at the lower end of one side of the guide shell 4, and a push plate 8 is fixedly mounted on one end of the piston rod of the electric push rod 7, and the push plate 8 is arranged at the same level as the blind box 5;

[0041] Through the design that a push plate 8 is fixedly installed on one end of the piston rod of the electric push rod 7, multiple blind boxes 5 can be placed inside the guide shell 4 at one time. When the blind box 5 inside the detection hole is pushed through by the pushing component 6, the blind box 5 falls and is then pushed into the detection hole by the electric push rod 7. The denomination of the coins placed inside is identified by the coin recognition component 3, so that the pushing component 6 can be cooperated to quickly count the coins in multiple blind boxes 5.

[0042] Further, both ends of the upper surface of the inductor converter 304 are provided with enclosures 12, and a detection cavity is formed between the two sets of enclosures 12, the detection cavity is arranged vertically corresponding to the inductor converter 304, and one end of the two sets of enclosures 12 on the opposite side is provided with a mounting hole, and a spring push rod 9 is arranged inside the mounting hole, the piston rods of the two sets of spring push rods 9 are arranged oppositely, and the piston rods of the two sets of spring push rods 9 are fixedly installed with a limit block 10, and one side of the limit block 10 is arranged obliquely;

[0043] By designing that one side of the limit block 10 is inclined, when the blind box 5 is pushed to one side of the limit block 10, the blind box 5 will be blocked by the limit block 10, so as to be automatically positioned to the best position for electromagnetic induction. Therefore, the coin identification component 3 can accurately identify the denomination of the coin. As the two sets of push rods 603 rotate, the blind box 5 is pushed and can follow the inclination of one side of the limit block 10, so that the blind box 5 squeezes the limit block 10, so that the blind box 5 can move out of the detection hole.

[0044] When the subsequent blind box 5 enters the detection hole through the electric push rod 7, the limit block 10 can be automatically reset under the action of the spring push rod 9 to block the subsequent blind box 5 entering, thereby facilitating the accurate identification of the coins inside the subsequent blind box 5.
