In today's era of convenient consumption, vending machines have spread throughout the streets and alleys, becoming one of the common shopping channels in people's lives. However, in order for these vending machines to provide us with continuous and stable service, and to maximize their commercial value, regular and scientific maintenance and upkeep are essential, which can be regarded as the key to extending their service life. Doing this step well can not only reduce the frequency of malfunctions and ensure operational efficiency, but also save the cost of replacing equipment, allowing vending machines to maintain good performance over the long term.
1、 External cleaning and maintenance
（1） Body cleaning
Vending machines placed in different environments are easily contaminated with dust, stains, etc. Over time, not only does it affect their appearance, but it may also have adverse effects on the machine's heat dissipation and other functions. Therefore, regular cleaning of the aircraft body is a fundamental and important maintenance step.
You can use a soft, clean damp cloth to gently wipe the exterior of the vending machine to remove dust and stains from the surface. For stubborn stains, you can dip in a mild cleaning agent to wipe them off, but be careful not to let the cleaning agent flow into the gaps or interfaces inside the machine to avoid damaging the internal electronic components. For example, vending machines placed on the street may get dirty from dust raised by passing vehicles, or vending machines near restaurants may get some oil stains. Regular cleaning can keep them clean and leave a good impression on consumers.
（2） Display screen maintenance
Nowadays, many vending machines are equipped with display screens to showcase product information, operation tips, and advertisements. The clarity and sensitivity of the display screen directly affect the shopping experience of users.
In daily maintenance, it is necessary to gently wipe the screen with a dedicated screen cleaning cloth to remove fingerprints, dust, etc., to keep the screen clean and transparent, and to improve its display effect. At the same time, sharp objects should be avoided from touching the screen to prevent scratches or even breakage, ensuring that it can display various information normally and facilitate consumers' operation and purchase of goods.
2、 Internal cleaning and organization
（1） Cargo clearance
The cargo aisle of a vending machine is a critical part for storing and shipping goods. During the continuous process of goods entering and leaving, it is easy to leave some debris, packaging paper, and other foreign objects. If these miscellaneous items are not cleaned up in a timely manner, they may cause blockages in the cargo passage, affect the normal shipment of goods, and even damage the packaging of goods, leading to malfunctions such as cargo jams.
Regularly open the cargo aisle of the vending machine, use tools such as a small brush or vacuum cleaner, carefully clean the debris and dust in the aisle, and ensure that the aisle is clean and smooth. For cargo lanes with spring devices, it is also necessary to check whether the elasticity of the spring is normal, whether there is any deformation or damage. If any problems are found, they should be replaced in a timely manner to ensure that the goods can be pushed out of the cargo lane normally, so that every shopping can be completed smoothly.
（2） Internal overall cleaning
In addition to the cargo aisle, other areas inside the vending machine, such as the bottom and corners, are also prone to dust and debris accumulation and require regular and comprehensive cleaning. Small cleaning tools can be used to thoroughly clean various parts inside the machine, keeping the internal environment clean and tidy.
In addition, it is necessary to check whether the internal wires, plugs, and other connection parts are loose, whether there are signs of damage or aging. If these problems exist, they should be repaired or replaced in a timely manner to prevent safety accidents caused by circuit problems, ensure the normal operation of the vending machine's electrical system, and lay the foundation for the stable operation of the machine.
3、 Inspection and maintenance of mechanical components
（1） Shipping system maintenance
The delivery system of a vending machine is like its "hands and feet", and its normal operation is crucial. Regularly inspect the operation of components such as the shipping motor, transmission belt, and rollers to see if there are any signs of wear, looseness, or jamming.
For example, if there is insufficient power in the shipment motor, it may cause the product to be unable to be launched smoothly; If the transmission belt is too loose, it will affect the transmission of power and make the shipment difficult. For these issues, it is necessary to adjust, tighten or replace the corresponding components in a timely manner to ensure that the shipping system can accurately and quickly deliver the goods to customers, avoiding embarrassing situations such as stuck goods and non shipment, and improving customers' shopping experience.
（2） Currency recognition and payment system maintenance
The currency recognition system (if the vending machine supports cash payments) needs to maintain high-precision recognition capabilities. It is necessary to regularly clean the dust and dirt inside the currency recognizer, check the sensitivity of the sensor, and update and upgrade the recognition program to ensure that it can accurately recognize currencies of different denominations, preventing problems such as coin ingestion and misjudgment of currency value.
For payment systems, whether it is QR code payment or facial recognition payment, it is necessary to ensure stable network connections, secure and reliable payment interfaces, and regularly update and maintain relevant software to ensure that customers can complete payments smoothly, avoid losing customers due to payment failures, and maintain a good operating order for vending machines.
4、 Maintenance of refrigeration and heating systems (for vending machines with related functions)
（1） Refrigeration system
In vending machines that sell beverages, fresh fruits and vegetables, and other products that require low-temperature storage, the refrigeration system is one of the core components. Regularly check the operation status of the refrigeration compressor, check for signs of leakage in the refrigeration pipeline, and ensure that the pressure and content of the refrigerant are normal.
At the same time, clean the condenser and evaporator of the refrigeration system to remove dust and debris attached to them, as these accumulations can affect heat exchange efficiency and reduce refrigeration efficiency. Through these maintenance measures, it is ensured that the refrigeration system can continuously and stably provide a suitable low-temperature environment for goods, prevent goods from deteriorating due to high temperatures, ensure product quality, and extend the service life of the refrigeration system itself.
（2） Heating system
For vending machines that sell hot drinks, hot food, and other items with heating functions, the heating system also needs to be carefully cared for. Check whether the heating element is working properly, whether the temperature controller can accurately control the temperature, and whether the heating pipeline is unobstructed.
During winter or when hot food is needed, ensure that the heating system can quickly and effectively heat the goods to the appropriate temperature, meet consumers' needs for hot drinks and food, and avoid safety hazards caused by heating system failures, so that the heating function of the vending machine can always be reliable and stable.
5、 Regular comprehensive testing and professional maintenance
（1） Regular comprehensive testing
Operators should develop detailed maintenance plans and conduct comprehensive inspections of vending machines at fixed intervals (such as monthly, quarterly, etc.). This inspection covers various aspects from external to internal, from mechanical components to electronic systems, just like conducting a comprehensive "physical examination" of a vending machine. Through detailed inspection records, potential problems are discovered in a timely manner, and corresponding repair and maintenance measures are arranged according to the severity of the problem.
For example, in the monthly inspection, the focus can be on the cleanliness of the appearance, the smoothness of the cargo passage, and the operation status of the payment system; And quarterly inspections can provide a more in-depth evaluation of the wear and tear of mechanical components, as well as the performance of refrigeration or heating systems. Through this periodic comprehensive inspection, the vending machine is always in good operating condition.
（2） Professional maintenance team intervention
Although some simple daily maintenance work can be completed by operators themselves, professional maintenance teams are still needed for some more complex fault diagnosis and repair work. Professional technicians possess specialized knowledge and tools, enabling them to more accurately identify problems and take effective solutions.
Establish long-term cooperative relationships with professional vending machine maintenance companies to ensure timely professional support when encountering difficult problems, quickly repair faults, minimize downtime, ensure the normal operation of vending machines, extend their service life, and lay a solid foundation for the long-term stable profitability of vending machines.
In short, the maintenance and upkeep of vending machines is a systematic and long-term task that requires operators to take every aspect seriously and not overlook any details. Only through careful care can vending machines continue to provide convenient shopping services to consumers in the test of time, achieve their maximum commercial value, and contribute to the development of the retail industry.
