Description

Technical Field

[0001] This utility model relates to the field of electronic scale technology, and in particular to an intelligent payment and collection electronic scale. Background Technology

[0002] With social progress and improved living standards, consumers and businesses have higher expectations for efficiency, accuracy, and service quality in commodity transactions. However, traditional electronic scales, due to their inherent limitations, are no longer able to meet the demands of the modern business environment.

[0003] In terms of functionality, traditional electronic scales are relatively simple, relying mainly on manual operation for product identification and settlement. This is not only time-consuming and labor-intensive but also prone to human error, affecting transaction efficiency. Furthermore, traditional electronic scales also have shortcomings in their display. Some scales lack a display screen or have only a single screen with a fixed viewing angle, unable to be adjusted according to user needs, thus reducing the user experience. Customers cannot see transaction information, resulting in insufficient transparency and increasing the risk of transaction disputes. Additionally, the smooth surface of the weighing pan on traditional electronic scales (such as those made of stainless steel) allows items to easily slide or roll, affecting the accuracy and stability of weighing. Some unscrupulous merchants may exploit these vulnerabilities to cheat, seriously harming consumer rights.

[0004] For suburban areas and many small retail shops, staff are scarce and often have to perform multiple tasks (purchasing, stocking, weighing, organizing, cashiering, and customer service, etc.). Traditional electronic scales lack intelligent design and cannot assist staff or reduce their workload.

[0005] To address these issues, smart electronic scales equipped with image acquisition devices and display structures have been introduced into the market to improve ease of operation and transaction transparency. For example, patent application CN114543962A discloses a weighing device for intelligently identifying non-standard goods; patent application CN107767590A introduces a commercial barcode electronic scale that automatically identifies items and retrieves price information through an image recognition module, the identification process of which includes steps such as image preprocessing, segmentation, feature extraction, and classifier matching; patent application CN107084780A further proposes to combine weight and image features to construct a commodity feature database to improve recognition accuracy. However, these smart electronic scales mainly focus on optimizing recognition algorithms or data processing logic, and their physical structures basically follow traditional designs, revealing several structural defects in practical applications: the weighing pan is made of smooth stainless steel, which not only has poor anti-slip performance, making it easy for goods to slip, but also easily interferes with image acquisition due to surface reflection, affecting recognition stability; the display screen is mostly fixed, with no adjustable viewing angle, making it difficult to adapt to the viewing needs of users of the same height or standing position, weakening the readability of transaction information and interactive experience.

[0006] It is evident that while existing smart electronic scales have achieved intelligence at the functional level, their structural design has failed to fully adapt to the newly added functions such as image acquisition and human-computer interaction, thus hindering the full realization of the intelligent effects. Therefore, it is urgent to improve the imaging conditions, increase the stability of product placement, and enhance information visibility through structural improvements without altering the existing image recognition and data processing procedures, in order to fully leverage the actual effectiveness of existing intelligent functions. Utility Model Content

[0007] To address the shortcomings of the existing technology, this utility model provides an intelligent, anti-interference, anti-slip, stable, and highly adaptable electronic payment scale.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An intelligent electronic payment scale includes a display system, a column, a weighing platform, and a controller. The weighing platform is connected to the lower end of the column. The column has a hollow structure, and a camera is installed in its upper part for automatic product identification and label recognition. The camera faces the weighing platform surface, and its field of view covers the products to be weighed, ensuring fast and accurate identification of items, reducing human error, and improving payment efficiency.

[0010] The weighing platform includes a weighing pan and a weighing base. The surface of the weighing pan is treated with a frosted finish, which prevents smooth or easily rolling items from rolling on a smooth surface, ensuring the stability of the goods during the weighing process and facilitating the user's weighing operation. It also avoids light reflection interfering with the camera's recognition of the goods, affecting the accuracy of item recognition, reducing weighing errors and recognition failures, and improving the accuracy and reliability of the weighing and recognition process.

[0011] The display system includes a main control screen, a customer display screen, and an adjustable bracket. The main control screen and the customer display screen are installed back-to-back and are each connected to one end of the adjustable bracket via a hinge. The base of the adjustable bracket is fixed to the upper end of the column, allowing users to adjust the angle and position of the screen as needed. This facilitates user operation of the touchscreen, ensures clear viewing of content, and adapts to users of different heights or the placement of the weighing pan, thereby improving user convenience and overall visual experience.

[0012] The main control screen uses a touchscreen, replacing the traditional keyboard input method. This not only provides an intuitive and convenient operating experience and clear data display, but also displays image information, enhancing the overall user experience. The customer display screen faces the customer and clearly displays information, prices, and the checkout process, making it easy for customers to understand their shopping experience. It also functions as an advertising display, providing rich visual content to further optimize service quality and enhance the customer's shopping experience.

[0013] The rotating shaft is equipped with a damping self-locking mechanism, which enables the display screen to remain stably in the position without rotating on its own after the angle is adjusted by external force, ensuring the stability and reliability of the display screen system and meeting the needs of different scenarios.

[0014] A scanner is installed in the middle of the column, on the same side as the customer display screen, for customers to scan codes to pay. Whether it is a QR code or a barcode, it can be quickly recognized, greatly improving payment efficiency and convenience. Customers can easily complete the payment process with a simple scan and enjoy a fast and secure shopping checkout experience.

[0015] A printer is located in the center of the column, on the same side as the main control screen, for printing checkout receipts, ensuring customers can clearly obtain detailed information about their purchased goods and proof of transaction. It can also easily print various labels, including price tags, inventory management labels, and promotional information labels. This not only improves store operational efficiency but also provides customers with more detailed product information and convenient shopping services, further increasing customer satisfaction and loyalty.

[0016] The camera is an AI camera, equipped with intelligent recognition and analysis functions, improving the accuracy of product identification. The printer is a thermal printer, utilizing thermal technology to achieve fast printing and low maintenance costs.

[0017] A scanner is installed in the middle of the column on the same side as the customer display screen, with the scanner port located on the customer side of the column. The scanner is connected to the controller via a data cable and is used to scan the customer's payment code, facilitating faster payment and simplifying the payment process.

[0018] The weighing platform is equipped with anti-slip and wear-resistant adjustable support feet to ensure the platform is balanced, stable, and does not shift, preventing items from slipping during the weighing process and improving efficiency and safety.

[0019] The weighing platform is equipped with a bubble level. By adjusting the height of the support feet to center the bubble in the level, the user can correct the level of the weighing pan, thereby ensuring the accuracy and stability of the weighed items and avoiding weighing errors caused by improper leveling, which could harm the interests of both the buyer and seller.

[0020] The bottom of the weighing platform is made of special anti-cheating sheet metal material to increase anti-cheating performance, effectively prevent illegal disassembly or tampering, and ensure measurement accuracy.

[0021] The controller is electrically connected to the display system, main control screen, customer display screen, AI camera, printer, and scanner weighing pan. As the central processing unit of the electronic scale, the controller coordinates the operation of various components through centralized control and data processing, realizing the automation and intelligence of the electronic scale (intelligent identification, weighing, rapid settlement, and printing functions).

[0022] The weighing platform's weighing pan is electrically connected to the controller via sensors to achieve accurate weighing.

[0023] The column has an L-shaped structure, with its vertical part fixedly connected to the display screen system and its horizontal part detachably connected to the weighing platform. This not only facilitates the upgrading and transformation of screenless weighing platforms but also greatly improves the mobility and ease of handling of electronic scales.

[0024] The scale base has a connection hole on its rear side (relative to the control panel) that is adapted to the horizontal part of the column. The horizontal part is inserted into the connection hole, and the two form a tight fit to ensure that the column can be stably connected to the scale base, while maintaining the integrity and stability of the entire electronic scale and structure.

[0025] The bottom surface of the horizontal part is fixedly connected to the weighing base by bolts.

[0026] The column is assembled from a front column shell and a rear column shell via a snap-fit ​​mechanism. This outer shell forms the column's outer casing, providing protection and support for each component, facilitating assembly and disassembly, and improving assembly efficiency and maintenance convenience. The absence of bolts and fasteners simplifies the structural design, reduces manufacturing costs, and results in an aesthetically pleasing appearance.

[0027] The electronic scale has a built-in speaker and a voice broadcast system to announce the item name, weight, price, payment amount, and transaction completion, providing users with clear and timely voice prompts. This enhances the user experience and makes operation more intuitive and convenient, especially for users with poor eyesight or difficulty operating the scale.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] 1. Intelligent and efficient. By introducing intelligent devices such as AI cameras to recognize items, multi-functional scanners, and printers, the system enables rapid identification and weighing of goods, automatic settlement, and quick invoice printing. This reduces manual operations, lightens the burden on merchants, improves work efficiency, and lowers labor costs.

[0030] 2. Enhanced User Experience. The dual-screen touch design with adjustable viewing angles enhances interactivity; the customer display screen shows product information, improving shopping transparency. This allows both customers and cashiers to see sales data, effectively preventing accounting errors. The main control screen and customer display screen are connected to the controller via data cables, enabling user interaction and data display.

[0031] 3. Accuracy and Safety. The weighing platform's pan surface features a frosted finish, preventing glare and slippage when items roll, ensuring accurate item identification and stable weighing. The sheet metal base of the weighing platform prevents unauthorized disassembly, enhancing anti-cheating capabilities and guaranteeing accurate measurement and fair transactions. Furthermore, the sheet metal base and frosted pan design effectively prevent unauthorized disassembly and item rolling, improving the electronic scale's safety and stability.

[0032] 4. Integrated design, compact structure.

[0042] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings and examples.

[0043] Example 1 (see Figures 1-3 , Figure 6 )

[0044] A smart payment and collection electronic scale includes a display system 1, a column 2, a weighing platform 3, and a controller.

[0045] in:

[0046] The display system 1 includes a main control screen 1-1, a guest display screen 1-2, and an adjustable bracket 1-3. The main control screen 1-1 and the guest display screen 1-2 are back-to-back with each other and are connected to one end of the adjustable bracket 1-3 via a hinge, so that the angle of the display screen can be adjusted as needed.

[0047] The main control screen 1-1 is used to operate and control the electronic scale, integrating operation and information display functions. Main control screen 1-1 adopts touch screen technology, providing users with an intuitive and user-friendly operation and settings experience. The touch screen can display data and images, and can also directly receive user data input, eliminating the need for a physical keyboard, offering two functions in one screen. The large screen width facilitates operation, promotes a friendly human-machine interaction, and improves work efficiency.

[0048] Customer display screens 1-2 are positioned facing the customer to display information such as product weight and price, increasing the transparency of transaction information and enhancing the user experience. Customers can clearly see key data such as the name, weight, unit price, and total price of the selected products, creating a transparent and fair shopping environment. This helps enhance customer confidence and avoids misunderstandings or disputes that may arise from a lack of transparency, thereby improving the overall shopping experience and the smoothness of the payment process. The main control screen and customer display screens are connected to the controller via data cables to ensure accurate, fast data transmission and real-time display.

[0049] The base of the adjustable bracket 1-3 is fixedly connected to the upper end of the column 2. The adjustable bracket 1-3 is used to mount two displays, providing stable support, and allows the display angle to be adjusted via a hinge to meet the viewing needs of different users. The hinge has a damped self-locking mechanism to ensure that the display can be locked in that angle position after the viewing angle is adjusted.

[0050] Column 2, serving as the supporting framework of the display screen system, is connected at its upper end to the adjustable brackets 1-3 and at its lower end to the weighing platform 3, ensuring the stability and load-bearing capacity of the overall structure. Column 2 adopts a hollow structure, which not only reduces its own weight but also accommodates devices such as the camera 4, printer 5, and barcode scanner 6, greatly improving space utilization efficiency.

[0051] Camera 4, mounted on the upper part of column 2, has its view directed at the work surface of weighing platform 3. Connected to the controller via a data cable, it is used to identify the identification information of items or goods on the weighing platform (such as physical characteristics of the goods, barcodes, QR codes, specific graphic or text markings, etc.). After capturing this information, the camera converts it into digital signals and transmits them to the controller for processing via the data cable.

[0052] The weighing platform 3, used for placing and weighing items, is connected to the column 2, together forming the main support of the electronic scale to ensure the stability and reliability of the overall structure. The weighing platform 3 includes a weighing pan 3-1 and a weighing base 3-2. The sensor on the weighing pan 3-1 is electrically connected to the controller. When goods are placed on the weighing pan, the sensor can quickly respond and capture the minute deformation caused by gravity, and convert this deformation into an electrical signal (proportional to the weight of the goods) which is then transmitted to the controller for processing.

[0053] The controller, acting as the intelligent command center of the entire system, processes the product image signals captured by the cameras using built-in decoding and deep learning algorithms. It parses the specific identification information of the products and compares this information with a pre-set database containing detailed product data to determine the product's type, price, inventory status, and other relevant information. Simultaneously, the controller calculates and analyzes the product's weight data based on the electrical signals transmitted by the weighing pan sensors (intensity, combined with the sensor's sensitivity coefficient, calibration data, and possible temperature compensation factors). All these product images, names, weights, and prices are then synchronously sent to the display system, presenting this information intuitively to the operator or customer in a digital or graphical format.

[0054] This electronic scale, integrating cameras and intelligent algorithms, significantly improves the speed and accuracy of product recognition, as well as the precision of weighing results. It enables the smart scale to quickly and accurately identify various products without manual input or tedious verification steps, significantly improving the efficiency of weighing and pricing. This frees up store clerks from the tedious work of weighing and pricing, allowing them to focus on providing other high-quality customer services. This not only avoids the time-consuming and labor-intensive problems of traditional manual operation, reducing the workload of staff and significantly improving overall work efficiency, but also reduces errors caused by human error or negligence, further enhancing weighing efficiency and accuracy, bringing unprecedented convenience and efficiency improvements to both merchants and customers.

[0055] Example 2

[0056] In this embodiment, the surface of the weighing pan 3-1 is treated with a frosted finish. On the one hand, the frosted surface increases friction, preventing round or easily rolling items from sliding or rolling on a smooth surface, ensuring the stability of the goods during weighing, facilitating user weighing operations, and ensuring accuracy and efficiency in every weighing. On the other hand, the frosted finish also effectively reduces direct light reflection on the weighing pan surface, avoiding interference from reflected light on the camera's identification of the goods, which could affect the accuracy and precision of item recognition, reduce inconvenience caused by recognition failures, and ensure the smooth operation of the entire weighing and settlement process.

[0057] Example 3 (see Figure 1 , Figure 3 )

[0058] In this embodiment, the column 3 has a built-in printer 5 for printing shopping lists, settlement information, etc. (printing weighing results, receipts, etc.), and prints quickly according to the controller's instructions. After printing, the output is automatically displayed through the outlet on the main control screen side of the column 3, providing customers with clear shopping vouchers or product identification codes to meet their information needs. In this example, the printer is a high-efficiency and energy-saving thermal printer, which prints quickly, requires no ribbon or ink cartridges, has low maintenance costs, and high printing efficiency. The thermal printer has a low noise level, creating a more comfortable and quiet shopping environment for customers, further enhancing the overall shopping experience.

[0059] Example 4 (see Figure 4 )

[0060] In this embodiment, a scanner 6 (e.g., model XB-76M6) is installed inside the column 3. The scanning port is located on the side of the customer display screen and is used to scan the customer's payment code, enabling fast and accurate product identification and customer checkout, thus improving transaction efficiency and accuracy. The scanner 6 also supports scanning product barcodes or QR codes, automatically identifying and reading product information, reducing the need for manual input of product information, avoiding the time and physical burden caused by manual operation, as well as the risk of errors.

[0061] Example 5 (see Example 5) Figure 3 )

[0062] In this embodiment, the camera is an AI camera, comprising: a lens assembly responsible for clearly capturing images of goods on the weighing pan; an image sensor that converts the image into electrical signals; a processor that uses a deep learning algorithm (such as a convolutional neural network CNN) to detect real-time images, the algorithm being trained on a large number of product images to obtain the types of goods; and a communication module that ensures smooth data transmission between the camera and other system components (weighing platform, display system). Compared to the controller's database-based product matching method for identification, the AI ​​camera's training and learning algorithm has stronger scalability and faster recognition speed, making it more convenient for upgrading traditional electronic scales and effectively reducing upgrade costs.

[0063] Example 6 (see Example 6) Figure 5 )

[0064] In this embodiment, the bottom of the weighing platform is made of a special anti-cheating sheet metal material to increase anti-cheating performance, effectively prevent illegal disassembly or tampering, and ensure measurement accuracy.

[0065] Traditional electronic scales are inadequate in preventing cheating, as the bottom of the weighing pan is easily disassembled illegally. This example uses a special sheet metal material as the bottom and support structure of the weighing pan. The special sheet metal material has the characteristics of high strength, corrosion resistance, and non-deformation, which can effectively resist illegal disassembly and damage. Its advantages are: (1) Enhanced structural strength. The special sheet metal material has high strength and hardness, making the bottom of the weighing pan and the support structure more robust and durable. This increases the difficulty of illegal disassembly, thereby reducing the occurrence of cheating. (2) Improved anti-vandalism capability. The special sheet metal material has good corrosion resistance and wear resistance, and can resist damage under various harsh environments and usage conditions. This further enhances the stability and reliability of the weighing pan and reduces the possibility of cheating. (3) Increased difficulty of cheating. Due to the high strength and hardness of the special sheet metal material, it is difficult for cheaters to illegally modify or damage the weighing pan through conventional means. Even if cheaters try to modify it, they will find it difficult to succeed due to the characteristics of the material. (4) Improved detection accuracy. The special sheet metal material undergoes strict process treatment during manufacturing, ensuring the accuracy of its size and shape. This helps ensure the stability and accuracy of the weighing pan during the weighing process, and improves the reliability of the test results.

[0066] By employing special sheet metal materials for anti-cheating design, a comprehensive improvement and enhancement has been achieved in the anti-cheating capabilities of traditional electronic scales. This strengthens the structural strength and anti-vandalism capabilities of the weighing pan, increases the difficulty of cheating, and improves detection accuracy, making electronic scale weighing safer, more reliable, and fairer.

[0067] Example 7 (see Example 7) Figure 3 )

[0068] In this embodiment, the bottom of the weighing platform 3 is provided with anti-slip and wear-resistant adjustable support feet to adjust the balance of the electronic scale, ensure that the weighing platform is stable and does not shift, prevent items from slipping during the weighing process, and improve the stability, portability and safety of use.

[0069] The weighing platform 3 is also equipped with a bubble level. Users can simply adjust the height of the support legs until the bubble in the level is centered to quickly and accurately correct the weighing pan to a horizontal position, ensuring the accuracy and stability of the weighing results. Its advantage lies in its ability to promptly detect any non-level state of the weighing platform, preventing weighing errors caused by platform displacement or external factors, and effectively protecting the fair trading rights of both buyers and sellers. Furthermore, it eliminates the shortcomings of traditional methods that require periodic checks with external levels and struggle to detect non-level states promptly. This not only improves work efficiency but also simplifies the operation process, providing users with a convenient and worry-free experience.

[0070] The bubble level can be embedded in the weighing pan or placed inside the side of the weighing platform (using a prism to refract the bubble to the side for observation).

[0071] Example 8 (see Example 8) Figures 1-6 )

[0072] In this embodiment, the column 2 has an L-shaped structure. The vertical part is fixedly connected to the display screen system 1, and the horizontal part is detachably connected to the weighing platform 3. This provides stable support, ensuring the stability of the electronic scale. It also facilitates upgrades and modifications to scales without a display screen. Furthermore, the weighing platform and the column display screen system can be separated as needed, and a base can be installed at the bottom of the column (see...). Figure 5 Expanding application scenarios and forming a series of products. The horizontal part has a wedge-shaped structure, and the rear side of the scale base has a connection hole that matches the wedge-shaped part of the column. The wedge-shaped part is inserted into the connection hole and fixed to the bottom surface of the scale base with bolts. It provides a stable support structure while facilitating disassembly and maintenance.

[0073] Example 9

[0074] In this embodiment, the column is connected by a snap-fit ​​mechanism between the front and rear column shells. The snap-fit ​​assembly of the column shells is no different in manufacturing process from fastener (bolts, etc.) assembly structures, but it has many advantages: (1) Easy assembly and disassembly. The snap-fit ​​structure makes the connection between the front and rear column shells simpler, eliminating the need for bolts and nuts. (2) High efficiency. The snap-fit ​​assembly process is fast and accurate, helping to improve the automation level of the production line and reduce labor and time costs. (3) Stable structure. The positioning grooves and protrusions of the snap-fit ​​structure ensure that the front and rear column shells can be accurately and firmly joined together, effectively dispersing pressure and improving the column's load-bearing capacity and stability. (4) Aesthetics. The absence of exposed screw holes and bolts makes the column's appearance simple and smooth, improving the overall aesthetics of the product. (5) Reduced manufacturing costs. The snap-fit ​​method eliminates the need for fasteners (bolts and nuts), reducing manufacturing costs. The assembly process is simple and reliable, reducing the risk of missing or dropped parts, affecting overall quality and rework costs.

[0075] I. Product identification, weighing, payment, and collection process

[0076] Item recognition:

[0077] The AI ​​camera captures images of items on the weighing pan using its built-in sensors.

[0078] The camera captures image data and transmits it to the controller of the electronic scale via a USB interface.

[0079] The controller uses built-in image processing algorithms to analyze and identify images to determine the type, quantity, or other relevant information of items.

[0080] Weighing:

[0081] When an item is placed on the weighing pan, a sensor underneath the pan detects the weight of the item.

[0082] The sensor converts the weight signal into an electrical signal and transmits it to the controller.

[0083] The controller processes the electrical signals and calculates the weight of the item.

[0084] show:

[0085] The controller sends the identified item information and calculated weight data to the main control screen and customer display screen of the electronic scale.

[0086] The screen displays the item's name, weight, and other relevant information, such as price and total price.

[0087] Scan to pay:

[0088] Customers can use the barcode scanner on the electronic scale to scan the product barcode or QR code to confirm their purchase information.

[0089] The barcode scanner transmits the scanned information to the controller.

[0090] The controller processes the scanned information and the preset payment system to generate a payment QR code or display the payment amount.

[0091] The scanner scans the customer's presented payment code to complete the payment.

[0092] Print the document:

[0093] After payment is completed, the controller sends the transaction information to the connected printer.

[0094] After receiving the information, the printer will print the transaction details on thermal paper or other media.

[0095] The printed receipt contains key information such as transaction time, item information, weight, price, and total price.

[0096] II. Principle

[0097] Image recognition principle: AI cameras use deep learning algorithms to analyze and recognize captured images. These algorithms learn the features of objects by training on a large amount of image data and are able to accurately identify these features in new images.

[0098] Weighing principle: Electronic scales use strain gauges or piezoelectric elements to sense weight. When an item is placed on the weighing pan, the sensor deforms and generates an electrical signal, which is proportional to the weight of the item. The controller calculates the weight by measuring this electrical signal.

[0099] Communication principle: AI cameras, barcode scanners, printers, and other devices transmit data to the electronic scale's controller via USB interfaces or other communication protocols. The controller, acting as the central processing unit, is responsible for receiving, processing, and sending data from each device.

[0100] Thus, through the connection and collaboration between the AI ​​camera and the electronic scale controller, the electronic scale can achieve automated and intelligent functions such as item recognition, weighing, display, scanning for payment, and printing of documents.
