[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0022] Refer to Figures 1 - 8 , the banknote counter of this embodiment includes a housing 110 and a banknote feeding plate 120. The banknote feeding plate 120 is installed on the housing for temporarily placing the banknotes to be counted. Inside the housing 110, along the running direction of the banknotes, a banknote twisting wheel 410, a sterilization component 500, a banknote feeding wheel 420, a CIS module 330, and a banknote receiving wheel 430 are sequentially installed. The banknote twisting wheel 410, the banknote feeding wheel 420, and the banknote receiving wheel 430 are respectively sleeved on a banknote twisting wheel shaft 411, a banknote feeding wheel shaft 421, and a banknote receiving wheel shaft 431. The banknote twisting wheel shaft 411, the banknote feeding wheel shaft 421, and the banknote receiving wheel shaft 431 are respectively rotatably assembled with the housing 110 in a circumferential manner. There are two sterilization components 500 and CIS modules 330, which are respectively located at the upper and lower end faces of the banknotes. During use, the sterilization component 500 emits ultraviolet light to irradiate the banknotes for sterilization; and the CIS module 330 scans the banknotes to determine the authenticity of the banknotes. Of course, a photoelectric counter is also provided between the banknote twisting wheel and the banknote receiving wheel. The photoelectric counter is used to count the number of banknotes passing through to count the number of banknotes.

[0023] During use, banknotes 01 are stacked on the bill feeding plate 120, and the bill separating wheel 420 rotates to convey the banknotes one by one between the two sterilization components 500. The sterilization module 500 sterilizes the banknotes by irradiating them with ultraviolet light. The banknotes are sent into the CIS module by a set of bill feeding wheels 420 for scanning and identification, and then sent into the bill receiving wheel 430 by another set of bill feeding wheels 420. The bill receiving wheel 430 stacks the banknotes in a pile at the bill receiving plate 111.

[0024] Preferably, the bill separating wheel shaft 411 is connected to the motor shaft of the first motor 310 through the first belt 610 to form a belt drive mechanism. The bill separating wheel shaft 411 is also connected to the nearby bill feeding wheel shaft 421 through the second belt 620 to form a belt drive mechanism. The two bill feeding wheel shafts 421 are connected through the third belt 630 to form a belt drive mechanism. During use, the first motor is started to drive the bill separating wheel and the bill feeding wheel to rotate for bill separating and bill feeding.

[0025] Preferably, the bill receiving wheel shaft 431 is connected to the motor shaft of the second motor 320 through the fourth belt to form a belt drive mechanism. After the second motor 320 is started, it can drive the bill receiving wheel 430 to operate for bill receiving.

[0026] See Figures 7 - 8 , the sterilization component 500 includes a fixing frame 510, an LED lamp board 340, a copper base 520, and a lens 530. The fixing frame 510 is directly or indirectly assembled with the housing 110. The copper base 520 and the LED lamp board 340 are installed on the fixing frame 510. The inside of the copper base 520 is a lamp slot 521. One end of the lamp slot 521 is open and the open end is closed by the lens 530. The LED lamp holder is installed in the lamp slot 521. LED lamp beads 341 are installed on the LED lamp board 340. After the LED lamp beads 341 are powered on, they emit UVC deep ultraviolet light for sterilization. Preferably, the lens 530 is pressed on the copper base 520 through a pressing plate 540, and the pressing plate 540 is installed on the copper base 520. The lens 530 is in a transparent state so that ultraviolet light can penetrate.

[0027] See Figures 9 - 15 , since banknotes more or less carry dust, solid impurities, fibers, hairs, etc., when they pass through the lens, it is very likely that the adsorbed impurities will be shaken off, so that the impurities are adsorbed on the lenses of the upper and lower sterilization components. At present, the main method is to regularly open the housing for cleaning, but this method requires complex disassembly, which is time-consuming and laborious. And it is very difficult to clean in time because the situation of the deposits on the lens cannot be detected. In response, the applicant has made the following improvements:

[0028] A plurality of irradiation probes are installed in the lamp slot 521, and the irradiation probes are used to detect the irradiance of the ultraviolet light emitted by the opposing LED lamp board. During use, first, the first motor is turned off to ensure there is no obstruction between the two sterilization components. Then, the LED lamp board on one side and the irradiation probe on the other side are started to detect the irradiance at this time, and then it is compared with the irradiance during lens cleaning. Once it is found that the decrease value of the irradiance exceeds the preset threshold, it is determined that cleaning is required, and then the management personnel can be prompted to clean or automatic cleaning can be performed through the cleaning mechanism.

[0029] The cleaning mechanism includes a cleaning frame 140, a cleaning brush 640, a driving fork 710, and a guiding frame 720. The guiding frame 720 is installed on the cleaning frame 140, and guiding grooves 721 and limiting plates 722 are respectively arranged on the guiding frame 720. The cleaning brush 640 is hollow inside and has several through suction slots 642 and bristles 641 on its outer wall, and the bristles are elastic; both ends of the cleaning brush 640 are non-rotatably assembled with one end of a first cleaning shaft 471 and one end of a second cleaning shaft 472 respectively. A hollow shaft hole is arranged inside the second cleaning shaft 472. The other end of the first cleaning shaft 471 and the other end of the second cleaning shaft 472 are respectively inserted into the fork slots 711 of the driving fork 710 and the guiding grooves 721 and are engaged and slidably assembled therewith. One end of the driving fork 710 is non-rotatably assembled with a fork shaft 450, the fork shaft 450 is rotatably assembled with the cleaning frame 140, and one end of the fork shaft 450 is connected to the motor shaft of a third motor 350. After the third motor 350 is started, it can drive the fork shaft 450 to rotate, thereby driving the driving fork 710 to rotate around the fork shaft. When the driving fork 710 rotates, it will drive the first cleaning shaft 471 and the second cleaning shaft 472 to slide along the guiding grooves 721, so that the cleaning brush 640 enters between the two lenses. In the initial state, the cleaning brush is located above the sterilization component 500 to avoid interfering with the passage of banknotes.

[0030] Preferably, the second cleaning shaft 472 is rotatably and sealingly assembled with a spring tube 480 through a sealing seat 730. The other end of the spring tube 480 is assembled with a rack seat 150, and the spring tube 480 has telescopic elasticity; the spring tube 480 is communicated with the air suction port of an air pump. The rack seat 150 is installed on the cleaning frame 140. During use, the spring tube flexibly adapts to the position of the cleaning brush 640 through telescoping, and when the air pump is started, it generates a suction negative pressure on the spring tube and the suction slots 642, so as to suck the impurities between the two lenses, thereby achieving cleaning. And the bristles can brush the lenses as the cleaning brush 640 moves between the two lenses, so as to achieve a better cleaning effect.

[0031] Preferably, in order to save energy and ensure the normal passage and sterilization effect of banknotes, the lenses of the two sterilization components 500 have a very small interval during use, which makes it impossible for the cleaning brush to enter between the two lenses in the initial state. Therefore, the applicant makes the following improvements:

[0032] An inner frame 130 is installed on the cleaning frame 140. The inner frame 130 is respectively assembled with the two screw sleeves 461 in a circumferentially rotatable and axially non-movable manner. The two screw sleeves are connected by a fifth belt 670 to form a belt drive mechanism. A worm gear 682 is sleeved on one of the screw sleeves 461. The worm gear 682 is in meshing transmission with a worm part 681. The worm part 681 is arranged on the lifting motor shaft 361. One end of the lifting motor shaft 361 is inserted into the lifting motor 360. The inside of the screw sleeve 461 is assembled with a screw rod 462 by screwing. And the bottom of the screw rod 462 is assembled with the fixing frame 510 of the sterilization component 500. When cleaning is needed, the lifting motor 360 rotates forward, thereby driving the two screw sleeves to rotate, and then driving the two screw rods to move upward through the thread, so as to increase the distance between the two lenses so that the cleaning brush can enter. After cleaning is completed, reverse the lifting motor to reset the corresponding sterilization component.

[0033] Preferably, cleaning gears 660 are respectively sleeved on the first cleaning shaft 471 and the second cleaning shaft 472. A rack 650 is installed on the rack seat 150. When the cleaning brush enters between the two lenses for cleaning, the cleaning gears 660 are in meshing with the rack 650, and then drive the fork to drive the cleaning brush to move back and forth between the two lenses, so as to drive the cleaning brush to continuously rotate forward and backward under the cooperation of the cleaning gears 660 and the rack 650 to increase the cleaning effect on the lenses. After cleaning is completed, the cleaning brush is reset and the sterilization component is reset.

[0034] Preferably, in order to save width space, the third motor 350 and the lifting motor 360 can be respectively installed in the inner cavity 112 of the housing, and then connected to the corresponding transmission shafts through belts. This is the prior art and will not be elaborated in this case.

[0035] The parts not detailed in the present invention are all well-known technologies in the art.

[0036] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations according to the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
