Description

Technical Field

[0001] This invention relates to the field of terminal welding technology, and more specifically, to a cableless integrated POS device with an embedded printing module. Background Technology

[0002] The embedded, cable-free integrated POS system is a compact commercial device that highly integrates functions such as checkout, receipt printing, QR code payment, and data uploading. It achieves instant receipt output through a built-in embedded printing module and adopts a wireless communication and cable-free structural design, eliminating the cumbersome external cables and independent module splicing methods of traditional POS counters. This results in a cleaner layout, simpler installation, and more flexible mobility. This type of device leverages embedded control technology to improve operational stability and response speed, supports multiple mainstream payment methods such as QR code payment, bank card swiping, and NFC sensing, and can synchronously upload transaction data to the back-end management system in real time. It meets the POS needs of various scenarios such as retail supermarkets, convenience stores, restaurants, and fresh food markets, possessing excellent compatibility, scalability, and ease of maintenance. It is an efficient and standardized intelligent POS solution for modern commercial retail scenarios.

[0003] However, existing integrated POS systems still have significant shortcomings in practical applications: Current equipment generally relies on manual handheld barcode scanners to scan and price each item individually, failing to achieve automatic product transport, positioning, and recognition. Cashiers must continuously repeat the actions of picking up, scanning, and placing items, resulting in high labor intensity, fatigue, and the speed of manual scanning being greatly affected by skill level, easily causing queues and congestion during peak hours, significantly reducing checkout efficiency. Furthermore, traditional equipment lacks automatic product centering; misaligned product placement directly leads to scanning failures, missed scans, or duplicate scans, further impacting checkout speed. In addition, conveyor-type checkout counters easily accumulate dust, water stains, debris, and other contaminants over long-term use, requiring frequent manual cleaning and cumbersome maintenance. Accumulated dirt also reduces transport smoothness and barcode recognition accuracy. Existing equipment also lacks integrated control for scanning and obstruction / cleaning functions, requiring separate drive and control components, resulting in complex structures and high costs, making it difficult to meet the demands of efficient, automated, and low-maintenance integrated POS systems.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figures 1-8 This invention provides a technical solution: an embedded cableless integrated POS device with a printing module, including a POS counter 1, an equipment platform 2 behind the POS counter 1, the POS counter 1 and the equipment platform 2 being an integrated structure design, an integrated POS machine 3 placed on top of the POS counter 1, a stand 4 fixedly installed on top of the POS counter 1, a barcode scanning camera 5 installed inside the stand 4, a conveyor frame 6 installed above the equipment platform 2, the barcode scanning camera 5 located in the middle above the conveyor frame 6, and a centering mechanism 7 set between the top surface of the equipment platform 2 and the bottom surface of the conveyor frame 6. In actual use, the goods are first placed above the conveyor frame 6 with the barcode facing upwards. The goods are conveyed by the conveyor frame 6 and pass under the barcode scanning camera 5 one after another, thus realizing automatic barcode scanning and settlement. The cashier only needs to monitor the data displayed by the integrated POS machine 3 to complete the checkout. In this process, the setting of the centering mechanism 7 can make the goods be conveyed in the center above the conveyor frame 6, which means that the barcode scanning camera 5 can more clearly illuminate the barcode on the goods. The centering mechanism 7 includes a fixed frame 71. Two symmetrically mounted transverse frames 73 are fixedly installed on the top of the fixed frame 71. Guide rails 74 are fixedly installed on the top of each transverse frame 73. A slider 75 is movably engaged with the top of each guide rail 74. A fixed plate 76 is fixedly installed on the top of each slider 75. Two connecting frames 72 are fixedly installed on the top of the fixed frame 71. Both connecting frames 72 are located outside the transverse frames 73. An electric telescopic rod 79 is installed on the top of each connecting frame 72. The output end of the electric telescopic rod 79 is movably connected to one side of the fixed plate 76. A centering plate 77 is fixedly installed on the top of the fixed plate 76. A [missing information - likely a component or component] is fixedly installed on one side of the centering plate 77. The centering frame 78 has an external plate 715 fixedly installed on one side of the fixed frame 71. Multiple sets of support frames 716 are fixedly installed between the bottom surface of the external plate 715 and the top surface of the equipment platform 2. The multiple sets of support frames 716 are equidistant. The external plate 715 and the support frames 716 are used to fix the centering mechanism 7. A rectangular plate 710 is fixedly installed in the middle of the transverse frame 73. A rotating shaft 711 is rotatably installed in the middle of the rectangular plate 710. A sleeve plate 712 is fixedly sleeved on the outer surface of the rotating shaft 711. A connecting rod 713 is movably connected between the sleeve plate 712 and the fixed plate 76. A gear plate 714 is fixedly installed at the bottom end of the rotating shaft 711.

[0023] During operation, when settling accounts for goods, the two electric telescopic rods 79 are controlled to extend and retract, thereby driving the two fixed plates 76 to move in opposite directions. The connecting rod 713, the rotating shaft 711, and the sleeve plate 712 ensure that the two fixed plates 76 move synchronously. When the goods pass the centering mechanism 7, the two moving fixed plates 76 drive the centering plate 77 and the centering frame 78 to move outside the conveyor frame 6. Through the contact of the centering frame 78, the goods are centered above the conveyor frame 6, thus achieving the purpose of centered conveying during the goods conveying process. In other words, the conveyed goods are always located below the barcode scanning camera 5, which facilitates the barcode scanning and settlement by the barcode scanning camera 5.

[0024] A blocking mechanism 8 is provided on the top of the conveyor frame 6. The blocking mechanism 8 includes a positioning plate 87, which is fixedly installed on the bottom of the conveyor frame 6. A rotating shaft 88 is rotatably installed inside the positioning plate 87. An installation sleeve 89 is fixedly installed on the outer surface of the rotating shaft 88. A blocking frame 810 is fixedly installed on one side of the installation sleeve 89. A snap-fit ​​frame 81 is fixedly installed on the top of the equipment platform 2. A movable block 82 is movably snapped inside the snap-fit ​​frame 81. A toothed plate 83 is fixedly installed on the top of the movable block 82. The toothed plate 83 meshes with the toothed disc 714. A movable frame 84 is fixedly installed on one side of the toothed plate 83. A rotating rod 85 is fixedly installed on the top of the equipment platform 2. A connecting frame 86 is rotatably installed on the outer surface of the rotating rod 85. One end of the connecting frame 86 is rotatably connected to one side of the movable frame 84, and the other end of the connecting frame 86 is rotatably connected to the outer surface of the rotating shaft 88.

[0025] During operation, when centering the product, that is, when the two fixed plates 76 move in opposite directions, they can drive the rotating shaft 711 to rotate. When the rotating shaft 711 rotates, it can synchronously drive the toothed disc 714 to rotate. Since the toothed disc 714 and the toothed plate 83 mesh with each other, the toothed plate 83 can synchronously move back and forth during the product centering process. In turn, under the action of the moving frame 84, the rotating rod 85 and the connecting frame 86, the rotating shaft 88 can be driven to rotate inside the positioning plate 87, controlling the opening and closing of the blocking frame 810. That is, during the product centering process, the blocking frame 810 can be driven to block the product, and the conveyor 6 can stop conveying. The blocked product stops behind the integrated cash register 3, which is convenient for the cashier to check and observe. After the barcode scanning camera 5 completes scanning, when centering the next product, the blocking frame 810 opens under the linkage action, allowing the product to pass smoothly, thus achieving the purpose of blocking the product and making it convenient for the cashier to check and observe.

[0026] The bottom of the conveyor frame 6 is provided with a cleaning structure 9, which includes an installation sleeve 91. The installation sleeve 91 is fixedly installed on the top of the equipment platform 2. The inside of the installation sleeve 91 is sealed with a sealing plug 92. A round rod 93 is fixedly connected to one side of the sealing plug 92. A linkage plate 94 is fixedly installed on the bottom surface of the movable frame 84. One end of the round rod 93 is fixedly connected to one side of the linkage plate 94. A conveying pipe 95 is fixedly connected to one side of the installation sleeve 91. A rectangular tube 97 is fixedly connected to one end of the conveying pipe 95. An air outlet frame 910 is fixedly connected to the bottom surface of the conveyor frame 6. Multiple air outlet nozzles 911 are equidistantly installed on the top of the air outlet frame 910. A drying element 912 is provided between the air outlet nozzles 911 and the rectangular tube 97. A one-way valve 96 is fixedly installed on the outer surface of the conveying pipe 95. An air inlet pipe 98 is fixedly connected to the outer surface of the installation sleeve 91. A two-way valve 99 is fixedly connected to the outer surface of the air inlet pipe 98.

[0027] During operation, as the moving frame 84 moves back and forth, it can also synchronously drive the round rod 93 to move synchronously, which in turn drives the sealing plug 92 to move back and forth inside the mounting sleeve 91. When the sealing plug 92 moves back and forth, it can draw outside air into the mounting sleeve 91 through the air inlet pipe 98, and then transport it to the inside of the rectangular tube 97 through the conveying pipe 95. Finally, it is transported to the inside of the air outlet frame 910 through the drying component 912, and then blown out towards the bottom of the conveying frame 6 through the air outlet nozzle 911, thereby cleaning the conveying frame 6.

[0028] The drying component 912 includes a heating box 9121, which is equipped with multiple heating wires. Connecting pipe 2 9123 and connecting pipe 1 9122 are fixedly connected to the upper and lower sides of the heating box 9121, respectively. The other end of connecting pipe 1 9122 is fixedly connected to rectangular pipe 97 and they are interconnected. The other end of connecting pipe 2 9123 is fixedly connected to the bottom surface of air outlet frame 910 and they are interconnected. When air enters the interior of heating box 9121 through rectangular pipe 97, it can be heated by the heating wires inside heating box 9121, so that the air blown towards conveyor frame 6 is hot air. If there is moisture on the surface of conveyor frame 6, the drying operation of conveyor frame 6 can be achieved, further improving the cleanliness of conveyor frame 6.

[0029] Specifically, the working process or principle of this embedded cableless integrated POS device with a printing module is as follows: In use, the goods to be settled are first placed stably on the conveyor surface of the conveyor rack 6, with the barcode side facing upwards. After starting the device, the conveyor rack 6 continuously conveys the goods forward at a set speed. When the goods are conveyed to the area of ​​the central mechanism 7, the device control system simultaneously activates the electric telescopic rods 79 on both sides. The electric telescopic rods 79 extend and retract, driving the fixed plate 76 connected to them. The slider 75 at the bottom of the fixed plate 76 moves linearly along the guide rail 74. To ensure smooth and seamless movement, the two side fixing plates 76 move synchronously towards each other under the drive of the electric telescopic rod 79, thereby driving the top centering plate 77 and centering frame 78 to move closer to the center of the conveyor frame 6. Utilizing the lateral contact of the centering frame 78, goods of different specifications and placement positions are forcibly pushed to the central axis of the conveyor frame 6, ensuring that the goods are always accurately positioned within the scanning area directly below the barcode scanner 5. This guarantees that the barcode scanner 5 can clearly, stably, and instantly identify the product barcode, completing automatic barcode scanning and pricing without requiring manual handheld barcode scanning.

[0030] During the centering mechanism 7's movement to center and position the product, the translation of the fixed plate 76 synchronously pulls the connecting rod 713. The connecting rod 713 drives the sleeve plate 712 to rotate around the rotating shaft 711. The rotating shaft 711 rotates accordingly and drives the toothed disc 714 fixedly mounted at the bottom to rotate synchronously. Since the toothed disc 714 and the toothed plate 83 mesh with each other, the rotational motion of the toothed disc 714 is converted into the horizontal linear movement of the toothed plate 83. The movable block 82 at the bottom of the toothed plate 83 slides along the snap-fit ​​frame 81 in a directional manner to ensure that the toothed plate 83 moves stably without deviation. When the toothed plate 83 moves, it drives the movable frame 84 on one side to translate synchronously. The movable frame 84 then drives the connecting frame 86 to rotate around the rotating rod 85. The other end of the connecting frame 86 carries... The rotating shaft 88 rotates inside the positioning plate 87. When the rotating shaft 88 rotates, it drives the mounting sleeve 89 and the blocking frame 810 to rotate synchronously. When the product is under the barcode scanning camera 5 for scanning, the blocking frame 810 rotates downwards to the top of the conveyor frame 6 to limit and block the current product. At the same time, the conveyor frame 6 briefly pauses its conveying, so that the product stays stably in the scanning area, making it easy for the cashier to observe and verify the product information and price. After the product is scanned, the centering mechanism 7 resets and prepares to center the next product. The blocking frame 810 opens under the linkage, releasing the obstruction of the product. The conveyor frame 6 resumes operation, allowing the scanned product to be smoothly conveyed forward. This cycle of scanning, verification, and release of products is achieved in an orderly manner.

[0031] During the reciprocating horizontal movement of the movable frame 84 along with the blocking mechanism 8, the linkage plate 94 at the bottom of the movable frame 84 moves synchronously and pulls the round rod 93 fixed thereto to perform reciprocating linear motion. The round rod 93 drives the sealing plug 92 at its end to perform reciprocating sealing sliding inside the mounting sleeve 91. When the sealing plug 92 is pulled backward, the second check valve 99 opens and the first check valve 96 closes, and outside air is drawn into the mounting sleeve 91 through the air inlet pipe 98 to complete the air intake. When the sealing plug 92 is pushed forward, the second check valve 99 closes and the first check valve 96 opens, and the air inside the mounting sleeve 91 is squeezed into the conveying pipe 95, and then conveyed to the rectangular tube through the conveying pipe 95. The air is evenly distributed within 97; the air then enters the heating chamber 9121 of the drying component 912. The heating wire in the heating chamber 9121 is energized to generate heat, which heats and dries the air flowing through it. The hot air enters the air outlet frame 910 through the connecting pipe 1 9122, the heating chamber 9121, and the connecting pipe 2 9123 in sequence. Finally, it is evenly sprayed upwards by multiple air outlet nozzles 911 evenly distributed on the air outlet frame 910, continuously blowing and cleaning the conveying surface of the conveyor frame 6 to remove dust, debris, water stains and other impurities. At the same time, the hot air completes the drying process, keeping the surface of the conveyor frame 6 clean and dry, and avoiding stains from affecting the stability of product conveying and the barcode recognition effect.

[0032] After all items have been automatically scanned, the information is transmitted to the integrated cash register 3 in real time. The integrated cash register 3 automatically completes price accumulation, settlement, and payment verification, and quickly prints the cash receipt through the built-in embedded printing module. The entire device adopts a cable-free integrated design with no exposed connecting wires. The overall structure is compact and the operation is stable, realizing an integrated intelligent cash register operation with automatic feeding, automatic centering, automatic scanning, automatic verification, and automatic cleaning.

[0033] It should be noted that the integrated cash register (3) and the conveyor (6) are existing devices or equipment, or devices or equipment that can be implemented by existing technology.
