Description

Technical Field

[0001] This utility model belongs to the field of financial service equipment, and specifically relates to a banknote counting and verification module. Background Technology

[0002] ATM, or Automated Teller Machine, is a small machine set up by banks in various locations. It uses a magnetic stripe on a plastic card the size of a credit card to record the customer's basic account information (usually a bank card), allowing customers to use the machine to perform bank counter services such as withdrawals, deposits, and transfers. Most customers refer to this self-service machine as an automatic teller machine.

[0003] ATMs can only withdraw cash. When a cardholder withdraws cash, the machine removes banknotes one by one from the cash box and conveys them through a channel to a banknote detection module for verification of authenticity and circulation, while recording the serial number. Banknotes that pass the verification are stacked together, and when the required number of banknotes is reached, the entire stack is delivered to the cardholder. Banknotes that are not suitable for circulation are sent back to a dedicated collection box for bank administrators to count and inspect.

[0004] Currently, in ATM cash withdrawal modules, when a cardholder withdraws cash, a cash-collecting mechanism removes the required denomination of banknotes one by one from the cash box and conveys them to the banknote inspection module via a conveyor channel. The banknote inspection module needs to check the physical dimensions of the banknotes, including length, width, and thickness, as well as their image spectrum and weak magnetic security lines. It also needs to simultaneously scan, identify, and record the serial numbers of the banknotes for future reference in case of disputes, and calculate the number of banknotes that have passed through. Therefore, a sophisticated banknote counting and verification module capable of recording a complete image of the banknotes is needed to achieve these functions. Utility Model Content

[0020] Please see Figure 1 This utility model provides a technical solution: A banknote counting and verification module includes a side plate 1 and a side plate 2. A base plate 3 is positioned between the side plates 1 and 2. Shafts 11 and 23 are positioned behind the base plate 3 between the side plates 1 and 2. Drive wheels 12 with equal spacing are mounted on shaft 11. A perforated hole is provided on the upper part of the base plate 3, through which the drive wheels 12 protrude. An image sensor 5 is positioned in the middle of the base plate 3, and a spectral sensor 10 and a thickness sensor 14 are positioned at the lower part of the base plate 3. A pressure plate 4 is positioned opposite the base plate 3. A micro-magnetic sensor 6 is positioned in the middle of the pressure plate 4. A pressure wheel 9 and a locking mechanism 8 are positioned at the upper middle part of the pressure plate 4. An image sensor is also positioned on the pressure plate 4 corresponding to the position of the image sensor 5 on the base plate 3. The lower part of the pressure plate 4 is hinged to the side plates 1 and 2. A limit hole 7 is provided on the side plate 1.

[0021] If the circumference of the drive wheel 12 or the pressure wheel 9 is even, then the other is odd. The pressure between the drive wheel 12 and the pressure wheel 9 is 20N to 35N. The micro-magnetic sensor 6 adopts a full-width coverage design. The image sensor 5 has a resolution greater than or equal to 300dpi. The thickness sensor 14 is symmetrically distributed from left to right. The image sensor 5 is symmetrically distributed from front to back.

[0022] Working principle: During operation, the pressure plate 4 is closed, and the locking mechanism 8 is fixed to the side plate 1 and the side plate 2 via a connecting rod, forming a channel with an internal gap of 5mm between the pressure plate 4 and the base plate 3. At this time, the drive wheel 12 is in close contact with the pressure wheel 9. When the banknote enters from below the channel formed by the base plate 3 and the pressure plate 4, the thickness sensor 14 continuously measures the thickness of the banknote. At the same time, the two thickness sensors 14 on the left and right judge the time interval of the numerical change to determine the degree of banknote tilt. As the banknote continues to move upward, the spectral sensor 10 detects the fluorescent anti-counterfeiting mark on the banknote and detects the spectrum of the banknote printing ink to determine the fluorescent anti-counterfeiting and the degree of banknote fading. The image sensor 5 performs double-sided image scanning of the banknote, identifies the serial number on the banknote, and checks the integrity and continuity of the image on the banknote. The micro-magnetic sensor 6 checks the micro-magnetic anti-counterfeiting of the banknote to determine whether the banknote is counterfeit or altered. The banknote continues to move upwards, contacting the drive wheel 12. Shaft 11 obtains power from the outside, and through the drive wheel 12 and pressure wheel 9, it clamps the banknote and continues to move upwards, conveying it to the rear channel and completing the technical verification.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
