Description

Technical Field

[0001] This utility model belongs to the technical field of self-service checkout devices, specifically, it relates to a self-service checkout device with a modular screen structure that is easy to assemble and maintain. Background Technology

[0002] Self-checkout machines, as automated payment devices, are widely used in modern business environments. They are typically installed in supermarkets, convenience stores, and shopping malls to provide consumers with a convenient and efficient self-checkout method. By operating the machine's screen interface, consumers can complete a series of checkout processes independently, including scanning items, verifying prices, and making payments. This significantly reduces the time spent waiting in line for cashiers, while also lessening the reliance of businesses on a large workforce of cashiers, thus improving overall operational efficiency.

[0003] However, traditional self-service checkout machines have revealed numerous drawbacks in actual use. In terms of structural design, their screen components are often not modular. This means that when a component within the screen assembly, such as the touchscreen, display screen, or related support frame, malfunctions, maintenance personnel need to disassemble the entire assembly. This involves numerous complex connection structures and parts, making the process extremely cumbersome, consuming significant time and effort, and potentially damaging other healthy components during disassembly, further increasing maintenance costs. For example, traditional screen assemblies may fix the touchscreen and display screen together using complex adhesive bonding or non-removable welding. Once the touchscreen is scratched or malfunctions and needs replacement, the entire assembly is practically rendered unusable, making individual component replacement and repair difficult. The assembly process of traditional self-service checkout machines is also complex. Due to the suboptimal connection methods between components and the lack of standardized, modular design, workers need to spend a significant amount of time aligning and installing each component and ensuring the robustness of numerous connection points during production and assembly. This greatly reduces production efficiency and hinders large-scale production and rapid market launch. Traditional self-service checkout machines suffer from a lack of easily maintainable structural design, making daily cleaning, inspection, and troubleshooting extremely difficult. For example, electronic components such as the PCB board located behind the screen assembly lack proper protection and convenient disassembly / removal mechanisms. When cleaning dust or testing whether components are functioning properly, maintenance personnel need to remove numerous unrelated parts to access the target components. This not only increases the difficulty of maintenance but also, during frequent disassembly and reassembly, can easily lead to loose connections between components, thereby affecting the stability and lifespan of the equipment. Utility Model Content

[0004] In view of this, the present invention provides a modular self-service checkout device with a screen structure that is easy to assemble and maintain, which solves the problem of low assembly efficiency of traditional self-service checkout machines and facilitates rapid assembly.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a modular self-service checkout device with a screen structure that is easy to assemble and maintain, comprising:

[0007] Front frame housing, which has front housing mounting holes;

[0008] The screen assembly is connected to the mounting holes of the front frame housing via machine screws, forming a detachable modular structure;

[0009] The screen assembly consists of a touch screen, a display screen, a display screen bracket, a screen mounting bracket, a screen assembly back cover, and multiple fasteners. The fixing holes of the screen assembly correspond to those of the front frame housing.

[0010] The technical advantages of this utility model's modular self-service checkout device, which facilitates assembly and maintenance, are as follows: The quick assembly and disassembly of the independent screen components and front frame significantly improves assembly efficiency and reduces the complexity of disassembling the entire machine during maintenance.

[0014] Adhesive-backed dustproof foam is bonded to the periphery of the touchscreen to seal gaps and prevent dust.

[0015] The display screen and the touch screen are stacked together, with sealing foam between them to achieve a seal.

[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the double-layer sealing structure of the adhesive-backed dustproof foam and the sealing foam effectively prevents dust from entering the gap between the touch screen and the display screen, extending the screen's lifespan. The elastic material of the foam automatically fills the assembly tolerances, avoiding light leakage or loosening caused by component size deviations.

[0017] Furthermore, the display screen is fixed by a display screen bracket, which is connected to the display screen by machine screws and fixed to the screen mounting bracket by anti-loosening nuts.

[0018] Furthermore, the screen mounting bracket fixes the touchscreen by adhesive bonding and is connected to the back cover of the screen assembly by anti-loosening nuts.

[0019] The screen mount serves as an intermediate connector, separating and fixing the touchscreen to the back cover to prevent damage to other components during maintenance.

[0020] Furthermore, the rear shell of the screen assembly covers the back of the display screen, and multiple PCB boards are provided thereon. The PCB boards are fixed inside the rear shell of the screen assembly by screws.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are: the back cover centrally encapsulates the PCB board, preventing external collisions or liquid corrosion of the circuit, and improving the reliability of the equipment.

[0022] Furthermore, a PCB board cover is provided on the outside of the PCB board, and the PCB board cover is fixed to the rear shell of the screen assembly by machine screws.

[0023] The beneficial effects of adopting the above-mentioned improvement scheme are: the groove of the PCB board cover and the back shell cooperate to form a sealed cavity, further isolating dust and moisture and protecting sensitive electronic components.

[0024] Furthermore, there are two display screen brackets, which are located on the left and right sides of the display screen respectively. The display screen brackets are L-shaped, with one end connected to the display screen and the other end fixed to the screen mounting bracket by an anti-loosening nut.

[0025] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: The L-shaped display screen bracket, combined with the machine screws, enhances the support strength of the display screen and prevents displacement caused by vibration during transportation or use. The display screen can be separated by removing the anti-loosening nut, eliminating the need to disassemble the entire unit and reducing maintenance costs. The L-shaped bracket makes full use of the internal space of the screen assembly, reduces structural redundancy, and provides multi-directional support.

[0026] Furthermore, the inner side of the rear shell of the screen assembly is provided with a slot for fixing the installation position of the PCB board.

[0027] The beneficial effects of adopting the above-mentioned improvement scheme are: the card slot design ensures the uniqueness of the PCB board installation position and avoids poor circuit contact caused by manual assembly deviation.

[0028] Furthermore, the edge of the PCB board cover is provided with a flange, which cooperates with the corresponding groove of the back shell of the screen assembly to form a sealed protective structure.

[0029] The beneficial effects of adopting the above-mentioned improvement scheme are: the mechanical interlock between the flange and the groove prevents the cover plate from falling off accidentally, while also enhancing the sealing performance.

[0030] Furthermore, the display screen bracket, screen mounting bracket, screen assembly back cover, PCB board, and PCB board cover are all fixed with machine screws and anti-loosening nuts.

[0031] The beneficial effects of adopting the above-mentioned improved solution are as follows: all components requiring fastening (display bracket, screen mounting bracket, screen assembly back cover, PCB board, PCB board cover) are fixed with machine screws and lock nuts, forming an independently detachable and assembleable module. Furthermore, the fixing holes of the screen assembly and the front frame housing correspond, enabling rapid assembly and maintenance. Specifically, the fasteners include adhesive-backed dustproof foam, sealing foam, machine screws, and lock nuts.

[0032] Compared with existing technologies, the advantages of this utility model, which provides a modular self-service checkout device that is easy to assemble and maintain, are:

[0033] Improved Assembly Efficiency: Traditional self-service checkout machines involve complex assembly processes with inconsistent connections between components, requiring workers to spend significant time on alignment, installation, and debugging. This new invention, however, designs the screen assembly as a modular structure. Each component is pre-assembled into a single module within the screen assembly. When assembling with the front frame housing, only machine screws are needed to connect the screen assembly to the mounting holes on the front frame housing. Actual testing shows that this structural design reduces assembly time per self-service checkout machine by approximately 30%-40% compared to traditional methods during large-scale production, significantly improving production efficiency and facilitating rapid market launch.

[0034] Reduced Assembly Difficulty: Traditional self-service checkout machines, due to their lack of modularity and standardization in structural design, require workers to possess high technical skills and extensive experience to skillfully complete the assembly work. However, the modular design of this invention simplifies the assembly process, allowing even newly hired workers to quickly learn and assemble the machines after simple training. This not only lowers the skill requirements for workers but also reduces the problem of inconsistent assembly quality caused by differences in worker skill levels, improving the consistency and stability of product assembly.

[0035] Reduced Repair Time: In traditional self-service checkout machines, when the screen assembly malfunctions, repair personnel need to spend a significant amount of time disassembling the entire assembly to locate the faulty component. However, the modular design of the screen assembly in this invention allows repair personnel to quickly locate the faulty component and replace it by removing the corresponding screws and lock nuts. For example, when the touchscreen malfunctions, repair personnel only need to disconnect a few connection points to remove the touchscreen from the assembly for replacement. The entire repair process can be shortened by approximately 50%-60% compared to traditional methods. This means that the equipment can be restored to normal operation more quickly, reducing downtime caused by equipment failure and improving the operational efficiency of businesses.

[0036] Reduced maintenance costs: Traditional self-service checkout machines are prone to damage to other working components during maintenance due to complex disassembly, thus increasing maintenance costs. The modular structure of this invention simplifies and simplifies the maintenance process, reducing the risk of damage to other components. Furthermore, the ability to quickly replace faulty parts reduces labor costs for maintenance personnel. Statistics show that using this structural design, maintenance costs can be reduced by approximately 30%-40% over the entire lifespan of the equipment compared to traditional self-service checkout machines.

[0062] The display screen is secured using a specially structured display screen bracket. The bracket employs an L-shaped design, with one end connected to the display screen using machine screws and the other end fixed to the screen mounting bracket using a lock nut. This L-shaped design not only provides stable support for the display screen but also cleverly utilizes space, resulting in a more compact and rational structure for the entire screen assembly. The screen mounting bracket secures the touchscreen via adhesive, ensuring a firm installation, and connects to the back cover of the screen assembly using the lock nut, thus organically combining all parts of the screen assembly together.

[0063] The back cover of the screen assembly covers the back of the display screen, protecting the screen and its internal electronic components. Multiple PCBs are housed within the back cover, secured with screws. The back cover also features slots on its inner side for precise PCB placement. This slot design not only facilitates PCB installation but also ensures that the PCBs do not shift due to vibration during operation, thus guaranteeing the stability of connections between electronic components and the accuracy of signal transmission. A PCB cover plate is located on the outer side of the PCBs, fixed to the back cover with machine screws. Its edge has flanges that engage with corresponding grooves in the back cover, forming a sealed protective structure to further prevent damage to the PCBs from dust and moisture.
