Description

Technical Field

[0001] This invention relates to the field of coin-operated equipment technology, specifically to a coin acceptor that is easy to disassemble and maintain. Background Technology

[0002] In numerous scenarios requiring coin-operated transactions, such as vending machines, public transport coin boxes, and amusement park coin acceptors, the coin acceptor, as a core component, is crucial for its performance and maintainability. Existing coin acceptors typically consist of a frame, coin channel, recognition device, and storage unit. The frame is generally manufactured using welding or one-piece molding to provide sufficient structural strength to support all components of the coin acceptor. The coin channel guides the movement of coins, while the recognition device verifies the authenticity of the coins; common recognition methods include magnetic detection, size detection, and image recognition. The storage unit holds verified coins. Currently, there are many types of coin acceptors on the market, but they generally have some shortcomings, including:

[0003] (1) Difficult disassembly and maintenance, and poor maintenance convenience: Existing coin acceptor frames mostly adopt welding or complex one-piece molding structures. Once internal components malfunction, such as damage to the recognition device or blockage of the coin channel, maintenance personnel need to spend a lot of time and effort to disassemble the entire coin acceptor shell, and may even need to damage part of the structure to carry out repairs. This not only increases maintenance costs, but also prolongs the downtime of the equipment and affects normal use. In the daily maintenance of coin acceptors, such as cleaning the coin channel and replacing the recognition device, the inconvenience of disassembling and assembling the shell makes the maintenance work cumbersome and results in low maintenance efficiency. Moreover, the complex structure also increases the risk of damaging other components during maintenance.

[0004] (2) Insufficient flexibility in coin handling: Some coin acceptors are not flexible enough in handling coins. For example, the method of handling counterfeit coins is limited, and users cannot easily take out counterfeit coins. The operation of taking out and putting in the collection box is not convenient enough, which affects the efficiency of coin collection and management.

[0005] Therefore, there is an urgent need to design a coin acceptor that is easy to disassemble and maintain in order to solve the problems of difficult disassembly and maintenance, poor maintenance convenience, and insufficient flexibility in coin handling of existing coin acceptors. Summary of the Invention

[0011] Preferably, a guide plate is installed at the top of the coin channel, and an electrically driven channel baffle is installed at the bottom of the coin channel. A gear steering device is connected to one side of the channel baffle via a drive shaft. The gear steering device is connected to a reducer via a drive shaft. The reducer is connected to a micro motor via a coupling. The micro motor, reducer, and gear steering device are all fixed on a bracket plate, and the end of the bracket plate is fixed to the inner wall of the side plate.

[0012] Preferably, the guide plate is fixed to the side of the vertical support by screws, and multiple curved guide grooves are machined on the inner side of the guide plate, with the bottom of the guide grooves converging on a coin passage.

[0013] Preferably, the coin channel has openings at the top and bottom.

[0031] Example 1

[0032] In specific implementations of this invention, such as Figures 1 to 12As shown, a coin acceptor that is easy to disassemble and maintain is provided. The base 1 has a trapezoidal structure and a rubber anti-slip pad at the bottom. This provides stable support for the entire coin acceptor and prevents it from sliding during use. The frame body 3 is welded to the base 1 at the bottom. The frame body 3 includes four vertical supports 301, with a crossbeam 302 welded between adjacent vertical supports 301. The vertical supports 301 have multiple slots 303 and insertion holes 304 at the top. As the main support structure of the coin acceptor, it supports other components and provides installation space for internal parts. The vertical supports 301 are welded together by the crossbeams 302, welded to the base 1, connected to the outer shell 2 and outer shell 4 through slots 303 and buckles 305, and connected to the top cover 5 through insertion holes 304 and insertion rods 306.

[0033] The outer shell plate 2 has a matching buckle 305 at the corresponding slot 303 position of the vertical support 301. Serving as the outer shell on one side of the coin acceptor frame body 3, it protects the internal components and enhances the aesthetics. The buckle 305 is fitted into the slot 304 for assembly on both the front and back sides of the upper part of the vertical support 301. The outer shell plate 4 has a matching buckle 305 at the corresponding slot 303 position of the vertical support 301. Serving as the outer shell on the other side of the coin acceptor frame body 3, it protects the internal components and enhances the aesthetics. The buckle 305 is fitted into the slot 304 for assembly on both the front and back sides of the lower part of the vertical support 301. The top cover plate 5 has a concave plate structure. A coin slot 501 is located at the lowest point of the concave surface of the top cover plate 5, and a matching insertion rod 306 is located at the corresponding insertion hole 304 position of the vertical support 301 at the bottom. Serving as the outer shell at the top of the coin acceptor, the coin slot 501 is used for inserting coins. Assembly with the frame body 3 is achieved by inserting the insert rod 306 into the insert hole 304.

[0034] Side plates 6 are welded to both sides of the main frame 3. One side plate 6 has a coin dispensing slot 602, and the other side plate 6 has a counterfeit coin dispensing slot 603. Both the coin dispensing slot 602 and the counterfeit coin dispensing slot 603 are fitted with rotatable doors 601 via hinges. A control panel 18 is located above the counterfeit coin dispensing slot 603. These side plates serve as the outer shell of the coin acceptor, protecting the internal components. The coin dispensing slot 602 is used to retrieve coins from the storage box 17, and the counterfeit coin dispensing slot 603 is used to retrieve counterfeit coins. The control panel 18 is used for electrical control of the coin acceptor. The side plates 601 are welded to the main frame 3, and the control panel 18 is fixed to the inner wall of the side plate 6 via hinges.

[0035] The guide plate 7 is fixed to the side of the vertical support 301 with screws. Multiple curved guide grooves 702 are machined on its inner side, converging at the bottom of a coin passage 701. This guide plate 7 guides the inserted coin along a predetermined path, allowing it to smoothly enter the coin channel 8. It is connected to the vertical support 301 with screws. The coin channel 8 has the guide plate 7 at the top and an electrically driven channel baffle 11 at the bottom. Openings are located at the top and bottom, respectively. A photoelectric sensor 9 is installed at the upper opening to monitor coin passage, and a camera 10 with built-in supplementary lighting is installed at the lower opening. The guide plate 7 provides a path for the coin, the photoelectric sensor 9 monitors whether a coin has passed, and the camera 10 verifies the authenticity of the coin. The guide plate 7 is fixed to the side of the vertical support 301 with screws, and the channel baffle 11 is connected to a gear steering mechanism 12 via a drive shaft. The photoelectric sensor 9 and the camera 10 are respectively installed at corresponding positions in the coin channel 8.

[0036] A photoelectric sensor 9 is mounted at the upper opening of the coin channel 8 to monitor whether a coin passes through the coin channel 8. A camera 10, equipped with supplemental lighting, is suspended within the frame body 3 via a matching camera bracket and is used to verify the authenticity of coins.

[0037] A gear steer 12 is connected to one side of the channel baffle 11 via a drive shaft. This controls the opening and closing of the coin channel 8, preventing counterfeit coins from entering the storage box 17, and can also be opened to allow users to remove counterfeit coins when needed. The other side is connected to the gear steer 12 via a drive shaft. The gear steer 12 is connected to a reducer 13 via a drive shaft. This reduces the transmission direction, transmitting the power output from the reducer 13 to the channel baffle 11. The reducer 13 is connected to a micro motor 14 via a coupling. This reduces the speed of the micro motor 14, increasing the torque and providing appropriate power for the opening and closing of the channel baffle 11. The micro motor 14 provides power for the opening and closing of the channel baffle 11. The end of the bracket plate 15 is fixed to the inner wall of the side plate 6. It is used to fix components such as the micro motor 14, reducer 13, and gear steer 12. Its end is connected to the inner wall of the side plate 6 via screws or other fixing methods. The micro motor 14, reducer 13, and gear steer 12 are all fixed to the bracket plate 15.

[0038] The splash-proof funnel 16 is fixed to the matching funnel bracket 1601. This prevents coins from splashing out when they enter the storage box 17 from the coin channel 8.

[0039] The bottom of the storage box 17 is machined with a slider 1703. It is used to store verified coins. The slider 1703 is slidably mounted on the slide rail 1701, which is fixed to the base 1. A limit block 1702 is mounted at the end of the slide rail 1701.

[0040] The control panel 18 includes a PCB board with a CPU main control chip, auxiliary control circuitry, and a power supply. The control panel 18 has a power button 1801 and a manual control button 1802 for the baffle. These are connected to a micro motor 14, a speaker, and a camera 10 via power cords to achieve overall electrical control. The power button 1801 is used to turn the coin acceptor on and off, and the manual control button 1802 is used to manually control the opening and closing of the channel baffle 11.

[0041] Based on the above structural features, this embodiment also provides a working process and working principle of a coin acceptor that is easy to disassemble and maintain: When the user inserts a coin into the coin slot 501, since the top cover plate 5 is a concave plate structure and the coin slot 501 is located at the lowest point of the concave surface of the top cover plate 5, this design allows the coin to slide smoothly into the coin slot 501 and enter the coin channel 8.

[0042] After the coin enters the coin channel 8, it first comes into contact with the guide plate 7. The guide plate 7 is fixed to the side of the vertical support 301 by screws, and its inner side is machined with multiple curved guide grooves 702. The bottoms of these guide grooves 702 converge on a coin passage 701. Guided by the guide grooves 702, the coin moves along a predetermined path and finally enters the subsequent part of the coin channel 8 through the coin passage 701.

[0043] When a coin passes through the upper opening of the coin channel 8, the photoelectric sensor 9 activates. Mounted at the upper opening of the coin channel 8, the photoelectric sensor 9 detects the passage of a coin and transmits a signal to the control panel 18. Upon receiving the signal, the CPU main control chip in the control panel 18 begins recording the coin's passage information, preparing for subsequent coin processing.

[0044] The coin continues to move downwards, and when it reaches the lower opening of the coin channel 8, the camera 10 with built-in lighting begins to operate. The camera 10 is suspended within the frame body 3 via a matching camera bracket. It can clearly capture images of the coin and transmit the image information to the control panel 18. The CPU main control chip in the control panel 18 analyzes the image and determines the authenticity of the coin using a preset algorithm. If the coin is genuine, the process proceeds to the next step; if the coin is counterfeit, the corresponding processing mechanism is triggered.

[0045] When the coin is determined to be genuine, the control panel 18 activates the micro motor 14. The micro motor 14 is connected to the reducer 13 via a coupling. The reducer 13 reduces the speed of the micro motor 14, increases the torque, and then transmits the power to the gear steering mechanism 12. The gear steering mechanism 12 changes the transmission direction, transmitting power to the drive shaft on one side of the channel baffle 11, causing the channel baffle 11 to open. The coin smoothly passes through the channel baffle 11 and enters the splash-proof funnel 16. The splash-proof funnel 16 is fixed to a matching funnel bracket 1601, preventing coins from splashing out when entering the storage box 17 from the coin channel 8. After passing through the splash-proof funnel 16, the coin falls into the storage box 17. When the camera 10 determines the coin is counterfeit, the control panel 18 will not open the channel baffle 11, and the counterfeit coin will be blocked above the channel baffle 11. At this time, the user can send a signal to the control panel 18 by pressing the manual control button 1802 above the counterfeit coin dispensing slot 603. After receiving the signal, the control panel 18 controls the micro motor 14 to rotate slowly. Through the transmission of components such as the reducer 13 and gear steering 12, the channel baffle 11 is slowly opened. The user can open the door 601 on the counterfeit coin dispensing slot 603 and take out the counterfeit coin.

[0046] Throughout the coin insertion process, the speaker will emit corresponding sound prompts based on different operations and states. For example, when a coin is inserted, the speaker will emit a "beep" sound to indicate that a coin has been inserted; when a counterfeit coin is detected, the speaker will emit a "beep beep" alarm sound to remind the user to deal with the counterfeit coin; when the device malfunctions, the speaker will also emit specific sound prompts to facilitate maintenance personnel in timely detection and handling of problems.

[0047] The storage box 17 has a sliding strip 1703 machined at its bottom, which slides onto the slide rail 1701. The slide rail 1701 is fixed to the base 1, and a limit block 1702 is fitted at the end of the slide rail 1701. The limit block 1702 prevents the storage box 17 from sliding off the slide rail 1701 during sliding. When it is necessary to remove coins from the storage box 17, the user only needs to open the door 601 on the coin outlet 602 and pull the storage box 17 outward. The storage box 17 slides along the slide rail 1701, and the coins can be easily removed.

[0048] When internal components of the coin acceptor malfunction, such as a damaged camera 10 or a blocked coin channel 8, requiring repair or replacement, maintenance personnel can easily disassemble and reassemble them. The outer shell plate 2 is connected to the upper slot 303 of the vertical support 301 via a snap-fit ​​305, enabling assembly on both sides; the outer shell plate 4 is connected to the lower slot 303 of the vertical support 301 via a snap-fit ​​305, also enabling assembly on both sides; the top cover plate 5 is assembled with the frame body 3 by inserting a rod 306 into the insertion hole 304 at the top of the vertical support 301. Maintenance personnel only need to disassemble the corresponding outer shell plate or top cover plate to repair or replace the faulty component without damaging the structure, greatly shortening maintenance time and reducing maintenance costs.

[0049] In summary, through the detailed explanation of the workflow and working principle above, it can be seen that this easy-to-disassemble and maintain coin acceptor has the advantages of simple operation, flexible coin handling, and easy disassembly and maintenance, and can meet the needs of various coin accepting scenarios.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
