Description

Technical Field

[0001] This utility model relates to the technical field of cash register barcode input equipment, and more specifically, to a cash register barcode rapid input device. Background Technology

[0002] The current product entry system primarily relies on supermarket cash registers scanning the 13-digit barcodes of each item. Customers move their purchased items one by one to the scanning area of ​​the cash register, aligning the barcodes with the camera for entry. However, this system presents several problems: First, while flat barcodes are easily recognized by the camera, bulk items with creases or folds, and items with curved packaging, also have curved barcodes, are difficult to scan. This necessitates repeated scanning, resulting in low entry efficiency and a poor user experience. Second, the existing cash register scanning ports lack protective structures. Their hard outer shells allow sharp-edged items to easily collide with the scanning port. Over time, the transparent protective glass of the scanning port can become damaged and scratched, affecting the clarity of images captured by the internal camera and further impacting entry efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a fast barcode input device for cash registers. This device, through the design of a semi-circular three-camera structure and an external support structure, can improve the success rate of barcode recognition for weighed bulk goods and curved packaged goods, achieving a fast input effect. At the same time, it reduces the impact and friction on the transparent protective glass of the barcode scanner, ensuring input efficiency for long-term use.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A rapid barcode input device for cash register products includes a cash register body. A receipt printer is installed at one end of the front side of the cash register body, and a barcode scanner is provided at the other end of the front side of the cash register body. A touch screen is fixed on the top surface of the cash register body, and a face recognition camera is provided above the touch screen. A base is provided on the front side of the cash register body at the four corners of the barcode scanner. The inner side of the base is welded and fixed to the front side of the cash register body, and a connecting rod is connected forward on the outer side of the base. Several mounting rods are connected in a rectangular pattern around the outer ends of the connecting rods, and a buffer anti-collision sleeve is fitted and fixed on the body of each mounting rod.

[0006] As a further optimization of this solution, each of the several mounting rods has an inwardly inclined winding rod at the junction of adjacent mounting rods. An elastic pull rope is fixedly connected to the body of the winding rod, and the elastic pull rope is connected inward to the four corners of the rectangular pressure frame. The rectangular pressure frame has a length and width of 40*30 mm and the width of the rectangular pressure frame edge is three to five mm.

[0007] As a further optimization of this solution, scanning bases are installed on the bottom surface inside the scanning port, as well as on the upper and lower inclined sides of the bottom surface. An infrared distance sensor and a scanning camera are installed on the surface of the scanning base, and a surrounding fill light is provided around the scanning camera.

[0008] As a further optimization of this solution, the infrared distance sensor, scanning camera, and fill light are all connected to the corresponding interfaces on the mainboard inside the cash register via wiring.

[0009] As a further optimization of this solution, the length of the connecting rod is one to two centimeters, and the rectangular pressure frame is initially located in the middle area of ​​several mounting rods.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0011] In this utility model, a connecting rod and mounting rod structure is designed around the existing barcode scanner to install a buffer anti-collision sleeve structure around the perimeter. When a customer enters the product barcode, the barcode scanner can perform a one to two centimeter limit scan, so that the relatively hard outer shell of the product cannot directly contact the transparent protective glass of the barcode scanner, reducing the collision and friction of the transparent protective glass of the barcode scanner and ensuring the input efficiency for long-term use.

[0012] This utility model features a three-dimensional scanning base structure (upper, middle, and lower), allowing the scanning camera to scan the barcode of a product from three directions. This results in a wider scanning coverage, improved recognition success rate for barcodes on curved packaging, and faster data entry.

[0013] In this invention, a rectangular pressure frame structure with an elastic pull rope is designed. Customers can press the folded barcode area of ​​the weighed bulk goods inward into the rectangular pressure frame, causing the folded barcode area to unfold and be captured by the internal scanning camera. This improves the recognition success rate of the weighed bulk goods barcode and achieves a fast data entry effect. Attached Figure Description

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] To address the issue that existing cash register barcode scanners lack a corresponding protective structure, have a hard outer shell, and are easily bumped by sharp-edged items, the transparent protective glass of the barcode scanner is prone to damage and scratches after long-term use, which affects the clarity of images captured by the internal camera and also affects data entry efficiency.

[0021] like Figure 1 As shown, this application includes a cash register body 1, a receipt machine 2 is installed at one end of the front side of the cash register body 1 and a barcode scanner 3 is provided at the other end of the front side of the cash register body 1, a touch screen 4 is fixed on the top surface of the cash register body 1 and a face recognition camera 5 is provided above the touch screen 4.

[0022] like Figure 2 As shown, a base 6 is provided on the front side of the cash register body 1 at the outer corner of the four perimeter of the scanning port 3. The inner side of the base 6 is welded and fixed to the front side of the cash register body 1, and the outer side of the base 6 is connected to the connecting rod 7. Several mounting rods 8 are connected in a rectangular distribution around the outer end of the connecting rod 7. Each mounting rod 8 is fitted with a buffer anti-collision sleeve 9. The length of the connecting rod 7 is one to two centimeters.

[0023] Specifically, the buffer anti-collision sleeve 9 can limit the scanning of the product by one to two centimeters when the customer enters the product barcode, so that the relatively hard outer shell of the product cannot directly contact the transparent protective glass of the barcode scanner 3, reducing the collision and friction of the transparent protective glass of the barcode scanner 3 and ensuring the input efficiency for long-term use.

[0024] To address the existing problem that barcodes are flat and easily recognized by cameras for flat products, but have wrinkles or folds on bulk products and curved packaging, making them difficult to recognize and requiring customers to scan repeatedly, resulting in low data entry efficiency and a poor user experience;

[0025] like Figure 2 and Figure 3 As shown, at the junction of several adjacent mounting rods 8, there are inclined winding rods 16 extending inward. Elastic pull ropes 10 are fixedly connected to the body of the winding rods 16, and the elastic pull ropes 10 are connected inward to the four corners of the rectangular pressure frame 11.

[0026] The rectangular frame 11 is 40*30 mm in length and width, which is larger than the basic size of the traditional 13-digit barcode (37.29*25.93 mm). This allows the folded barcode area to be pressed inward and protruded into the rectangular frame 11.

[0027] The rectangular frame has a border width of three to five millimeters, so it will not obstruct the image capture by the scanning camera 14 in the middle of the interior.

[0028] Scanner bases 12 are installed on the bottom surface of the scanning port 3, as well as on the upper and lower inclined sides of the bottom surface. Infrared distance sensor 13 and scanning camera 14 are installed on the surface of the scanning base 12. Surrounding fill lights 15 are provided around the scanning camera 14. The infrared distance sensor 13, scanning camera 14 and fill lights 15 are all connected to the corresponding interfaces on the main board inside the cash register body 1 through wires.

[0029] Specifically, for products with curved packaging, the scanning cameras 14 on the upper, middle, and lower scanning mounts 12, after focusing through the infrared distance sensor 13, can capture most of the curved barcode area image by the middle scanning camera 14. The images of the remaining areas above and below the curved barcode are supplemented by the upper and lower scanning cameras 14. Combined with the processor on the main board of the cash register 1, the three captured images are stitched together and integrated, resulting in a wider scanning coverage and improved recognition success rate of barcodes for products with curved packaging, achieving a fast data entry effect.

[0030] like Figure 2 As shown, the rectangular pressure frame 7 is initially located in the middle area of ​​several mounting rods 8. For bulk goods being weighed, such as... Figure 4As shown, customers can press the folded barcode area of ​​the weighed bulk goods inward into the rectangular pressure frame 7, causing the folded barcode area to extend inward along with the rectangular pressure frame 7. This allows the scanning cameras 14 in the upper, middle, and lower directions inside to capture a relatively complete barcode image, which can improve the recognition success rate of the barcode of the weighed bulk goods and achieve a fast data entry effect.

[0031] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
