Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0032] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0033] In one embodiment of the present invention, a coin thickness detection device is provided. Figure 1 , including a support 1, a sliding rod 2, a sliding ball 3, a ranging target end 4, a ranging detection end 5, a plate 6 and a spring 7.

[0034] The plate 6 is disposed below the support 1 and is configured to place the coins 8 to be detected. An extension plate 11 is disposed on the top of the support 1 and is configured to be mounted on a fixing bracket, thereby fixing the support 1.

[0035] The sliding rod 2 is arranged on the support 1 and can slide up and down in the vertical direction along the support 1. The ranging target end 4 is arranged at the upper end of the sliding rod 2 and the ranging target end 4 is at least partially arranged outside the support 1. The sliding ball 3 is arranged at the lower end of the sliding rod 2 and above the plate 6. The ranging detection end 5 is arranged above the ranging target end 4 and a first distance is provided between the lower surface of the ranging detection end 5 and the upper surface of the ranging target end 4. The spring 7 is arranged between the sliding ball 3 and the support 1 and is sleeved on the sliding rod 2.

[0036] Specifically, the support 1 has a first opening at the upper end, a second opening at the lower end and a cylindrical structure in the middle. The sliding rod 2 is arranged inside the cylindrical structure and its cross-sectional size is smaller than the size of the first opening. At least part of the ranging target end 4 at the upper end of the sliding rod 2 extends to the outside of the first opening. The size of the second opening is smaller than the diameter of the sliding ball 3, and the sliding ball 3 at least partially extends to the outside of the second opening. The height of the part of the sliding ball 3 extending to the outside of the second opening is not less than the thickness of the coin to be detected. The bottom of the sliding ball 3 is set at a second distance from the upper surface of the plate 6, and the second distance is less than the thickness of the coin to be detected. The material of the sliding ball 3 is preferably polyethylene, polypropylene or polystyrene to avoid losing coins during the coin detection process.

[0037] Since the diameter of the sliding ball 3 is larger than the size of the second opening, the sliding ball 3 can only partially leak out of the support 1, and the sliding rod 2 is confined inside the support 1. When the sliding ball 3 is pushed upward by the coin to be detected, the sliding rod 2 drives the ranging target end 4 to rise and approach the ranging detection end 5.

[0038] More preferably, a platform 31 is provided on the upper part of the sliding ball 3. The upper end of the spring 7 is disposed against the inner wall of the top of the support 1, and the lower end of the spring 7 is disposed against the platform 31.

[0039] In one embodiment of the present invention, the top of the distance measuring target end 4 is a planar structure, and the distance measuring detection end 5 is an ultrasonic distance measuring sensor. In this embodiment, the working principle of the coin thickness detection device is: according to the time difference between the ultrasonic distance measuring sensor transmitting the signal and the time difference between the ultrasonic distance measuring sensor receiving the signal and the ultrasonic propagation speed, the distance between the distance measuring target end and the ultrasonic distance measuring sensor is determined, and then the thickness of the coin can be determined.

[0040] In one embodiment of the present invention, the top of the ranging target end 4 is a planar structure, and the ranging detection end 5 is a radar ranging sensor. In this embodiment, the principle of coin thickness detection is: the radar ranging sensor transmits microwaves to the ranging target end 4, and the intensity of the microwaves reflected by the ranging target end 4 received by the radar ranging sensor is inversely proportional to the distance between the two, so the distance between the ranging target end and the radar ranging sensor can be determined, and then the thickness of the coin can be determined.

[0041] In one embodiment of the present invention, the top of the distance measuring target end 4 is a planar structure, and the distance measuring detection end 4 is a laser distance measuring sensor. In this embodiment, the principle of coin thickness detection is: the laser distance measuring sensor emits a laser beam to the distance measuring target end 4, and receives the laser beam reflected by the distance measuring target end 4, and the calculation module calculates the distance between the two according to the time from the emission to the reception of the laser beam, and then the thickness of the coin can be determined.

[0042] In one embodiment of the present invention, the distance measuring target end 4 is a magnet, and the distance measuring detection end 5 is a magnetic induction chip. In this embodiment, the principle of coin thickness detection is: the change in the distance between the magnet and the magnetic induction chip will cause the magnetic flux between the two to change, and the magnetic induction chip will output different electrical signals accordingly, that is, the output signal of the magnetic induction chip has a corresponding relationship with the distance between the magnet and the magnetic induction chip, thereby detecting the thickness of different coins.

[0043] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0044] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
