[0022] In a preferred embodiment, the automated inspection device includes an inspection camera module, which is used to inspect the product surface and scan QR codes. The inspection camera module includes two side inspection camera modules 3, an end face inspection camera module 4, and an upper surface inspection camera module 5. At least one of the two side inspection camera modules 3, the end face inspection camera module 4, and the upper surface inspection camera module 5 is integrated with a QR code scanning device.

[0023] The main camera module 21 is arranged on the air duct clamping device 2 and is associated with other camera modules so that the detection camera module can find the position of the product and perform detection.

[0024] In a preferred embodiment, the main camera module 21 is arranged on the air duct clamping device 2 and moves with the air duct clamping device 2. The air duct clamping device 2 clamps the product. Therefore, the positions of the main camera module 21 relative to the air duct clamping device 2 and the product relative to the air duct clamping device 2 are relatively fixed. The main camera module 21 only needs to know its own position. Preferably, its own position can be determined by connecting with a fixed position sensor signal.

[0025] In another preferred embodiment, the main camera module 21 includes a camera lens or a lens module, such as one or more of a single-lens camera module, a multi-lens camera module, a wide-angle camera module, a telephoto camera module, a stereoscopic vision camera module, a high-resolution camera module or a multi-spectral camera module, which can capture the position of the product and other camera modules to determine the product position.

[0026] In another preferred embodiment, the main camera module 21 may also detect the position of the product by infrared positioning, laser triangulation, ultrasonic imaging, etc.

[0027] The main camera module 21 can be associated with other camera modules by means of a network connection, such as Ethernet or a local area network, a Bluetooth connection, or a wired connection that can transmit position data and electrical signals.

[0028] The conveying device 1 conveys the product, reduces the pressure of manual transportation, alleviates the labor intensity of manual labor, and can also reduce labor costs. In addition, the conveying device 1 can accurately stop at a set point for easy detection.

[0029] The conveying device 1 is used to move the product from one position to another during the product positioning and detection process. The conveying device 1 can be selected from one or more of a conveyor belt, a roller conveyor, a slider conveyor, a chain conveyor, a screw conveyor, a vibrating conveyor and a pneumatic conveyor.

[0030] Furthermore, multiple camera modules adopt a distributed layout, and different sides of the product can be inspected at the same time. Accuracy is enhanced. By using multiple camera modules, including the main camera module 21, the side detection camera module 3, the end detection camera module 4 and the upper surface detection camera module 5, the device can capture and analyze all aspects and features of the product in an all-round way. This helps to improve the accuracy and reliability of detection.

[0031] The cooperation of multiple camera modules is multifunctional. The side detection camera module 3 can be used to detect the side features of the product, the end detection camera module 4 is used to detect the front and rear end features of the product, and the upper surface detection camera module 5 is used to detect the upper surface features of the product. This versatility makes the device suitable for different types of products and applications.

[0032] The cooperation of the conveying device 1, the air duct clamping device 2, the main camera module 21, the two side detection camera modules 3, the end surface detection camera module 4 and the upper surface detection camera module 5 improves efficiency. The automated detection device can detect products in different directions and positions at the same time by using the conveying device 1 and the air duct clamping device 2, as well as a combination of multiple camera modules. This parallel detection method greatly improves the detection efficiency.

[0034] like Figure 2 As shown, the performance detection host 6 can detect the performance fault of the product. The performance detection host 6 is connected to the product to simulate the working state of the product. In a preferred embodiment, the performance detection host 6 is used to simulate the internal environment of the refrigerator; further, the performance detection host 6 is located below the conveying device 1 and is equipped with multiple controllers and sensors, such as a CPU controller, a damper motor driver, a temperature sensor, a fan circuit, a thermal resistance detection circuit, and an ice turning circuit. These components can monitor and detect the performance and working state of the device, detect faults in time, and take corresponding measures.

[0035] Specifically, the performance detection host 6 retains some open sensor interfaces for detecting various data during the operation of the product, such as: surface light source, damper motor power, odor, negative ion content, and stepper motor power. Other data detections can be performed after later development. The performance detection host 6 is also provided with an LED indicator light. When the data deviates from the set range, the LED indicator light prompts. Preferably, the LED indicator light is integrated into the display panel 8 to facilitate user observation.

[0036] The introduction of the performance detection host 6 brings convenience to the control and management of the automated detection device. The CPU controller is connected to the damper motor driver, temperature sensor, fan circuit, thermistor detection circuit, ice-turning circuit, LED indicator light and power supply circuit to realize the control and management of each functional module to detect whether the product is working normally, thereby improving the functionality and reliability of the device.

[0037] Due to the connection between each functional module and the CPU controller, the functions of the performance detection host 6 can be easily expanded and upgraded to adapt to the ever-changing detection needs. The CPU controller in the performance detection host 6 acts as a central control unit, enabling the entire system to be centrally controlled and coordinated. In addition, the power consumption of each key component can be monitored and measured in real time. This helps to detect abnormalities and faults in a timely manner and take corresponding measures to ensure the normal operation and performance of the device.

[0038] Preferably, the performance detection host 6 also includes: a network module, the network module is connected to the CPU controller, and the network module is connected to the external server via the TCP protocol.

[0039] The performance detection host 6 is equipped with a network module to realize remote connection. By connecting to the external server via the TCP protocol, remote communication with external devices and systems is realized, which facilitates remote monitoring and management of the automated detection device.

[0040] The performance detection host 6 is equipped with a network module to realize data transmission. The network module can realize fast and stable data transmission, upload the detection data and results to an external server for analysis, storage and sharing, and provide more data processing and utilization methods.

[0041] The performance detection host 6 is equipped with a network module to realize remote maintenance. The existence of the network module makes remote maintenance and troubleshooting more convenient. The equipment can be monitored, repaired and upgraded through remote access and control, which improves the maintainability and reliability of the device.

[0042] The performance detection host 6 is provided with a network module, which is connected to the CPU controller and connected to an external server via the TCP protocol. This enables the device to exchange, share and remotely control data with other systems or devices, thereby improving the remote manageability and integration of the device.

[0043] The automated detection device further includes a two-dimensional code laser printing device, which is located at a previous station of the conveying device 1 , and the air duct clamping device 2 moves between the two-dimensional code laser printing device and the conveying device 1 .

[0044] The two-dimensional code laser printing device in the automated detection device can quickly identify the product. Through the two-dimensional code laser printing device, the two-dimensional code logo can be printed on the product quickly and accurately, which is convenient for subsequent tracking and identification.

[0045] The QR code laser printing device in the automated detection device can perform data association. The QR code can carry relevant data information, such as batch number, production date, etc., to achieve association and traceability between the detected objects and the detection results, thereby improving the accuracy and efficiency of data management.

[0046] The two-dimensional code laser printing device in the automated detection device can optimize the workflow. By setting the two-dimensional code laser printing device at the previous station of the conveying device 1 and moving it in coordination with the air duct clamping device 2, a continuous automated workflow can be achieved, thereby improving production efficiency and consistency.

[0047] like Figure 1 As shown, the air duct clamping device 2 includes: a three-dimensional moving component 22 and a clamping member 225. The main camera module 21 and the clamping member 225 are respectively arranged on the upper and lower sides of the three-dimensional moving component 22. The three-dimensional moving component 22 can drive the clamping member 225 and the main camera module 21 to move in three directions that are orthogonal to each other.

[0048] The three-dimensional moving assembly 22 includes: a first moving device 221 for a main camera, a main camera frame 222, a second moving device 223 for a main camera, a third moving device 224 for a main camera and a clamping member 225, wherein the first moving device 221 for the main camera lifts and lowers the main camera frame 222 in a vertical first direction, the second moving device 223 for the main camera is arranged on the main camera frame 222, the second moving device 223 for the main camera moves the third moving device 224 for the main camera in a horizontal first direction, the third moving device 224 for the main camera moves the clamping member 225 in a horizontal third direction, and the clamping member 225 clamps the product, and the first direction, the second direction and the third direction are orthogonal to each other.

[0049] The three-dimensional moving component 22 is flexible in clamping. The air duct clamping device 2 drives the clamping member 225 and the main camera module 21 to move along three mutually orthogonal directions through the three-dimensional moving component 22, so as to flexibly clamp and position the detected object and adapt to objects of different sizes and shapes.

[0050] The three-dimensional moving component 22 is precisely positioned, and the clamping member 225 and the main camera module 21 are respectively arranged on the upper and lower sides of the three-dimensional moving component 22. Through the fixing and movement of the clamping member 225, the precise positioning of the detected object can be achieved to ensure accurate detection position and angle.

[0051] The three-dimensional moving component 22 can move in three directions. The three-dimensional moving component 22 can move in three mutually orthogonal directions, such as front and back, left and right, and up and down. This mobility allows the clamping member 225 and the main camera module 21 to move freely in space to achieve all-round detection and positioning.

[0052] The side detection camera module 3 includes a guide rail 32 and a side camera 31 . The guide rail 32 extends along the setting direction of the conveying device 1 , and the side camera 31 is slidably disposed on the guide rail 32 .

[0053] The side camera 31 is slidably installed on the guide rail 32. This design allows the side camera 31 to be slidably installed and adjusted at different positions of the conveying device 1 as needed to scan the side of the product. The side camera 31 can be slidably installed on the guide rail 32 and can be used to shoot according to the position of the product.

[0054] The upper surface detection camera module 5 includes a plane moving component and an upper surface camera. The plane moving component drives the upper surface camera to move in two directions parallel to the horizontal plane and perpendicular to each other.

[0055] The plane moving assembly includes: a first moving device 52 for the upper surface camera and a second moving device 53 for the upper surface camera, wherein the first moving device 52 for the upper surface camera drives the second moving device 53 for the upper surface camera to move along a fourth horizontal direction, and the second moving device 53 for the upper surface camera drives the upper surface camera to move along a fifth horizontal direction, and the fourth direction and the fifth direction are perpendicular to each other, so that the upper surface of the product can be scanned at multiple angles. This plane moving capability enables the upper surface camera to perform a comprehensive scan and inspection of the upper surface of the product in a horizontal direction, thereby improving the comprehensiveness and accuracy of the inspection.

[0056] The automated inspection device also includes an outer frame 7, and the conveying device 1, the air duct clamping device 2, the main camera module 21, the side inspection camera module 3, the end face inspection camera module 4, the upper surface inspection camera module 5 and the performance inspection host 6 are all arranged in the outer frame 7, and a sunshade 71 is provided on the outer frame 7.

[0057] The outer frame 7 serves as the supporting structure of the device, accommodating the conveying device 1, the air duct clamping device 2, the main camera module 21, the side detection camera module 3, the end surface detection camera module 4, the upper surface detection camera module 5 and the performance detection host 6. The design of the outer frame 7 enables the various components to be firmly installed together, providing the structural support and stability required for the operation of the device.

[0058] A shading plate 71 is provided on the outer frame 7 to prevent external light from interfering with the detection process. The shading plate 71 can effectively reduce the interference and reflection of light, provide a relatively stable detection environment, and help improve the accuracy and reliability of the detection results.

[0059] The automated inspection device further includes a display panel 8, which is disposed outside the outer frame 7 and is connected to the side inspection camera module 3, the end face inspection camera module 4, the upper surface inspection camera module 5 and the performance inspection host 6 respectively.

[0060] The display panel 8 can display various data in the damper motor driver, temperature sensor, fan circuit, thermal resistor detection circuit, ice turning circuit, LED indicator light and power supply circuit as well as the data detected by the power sensor.

[0061] The display panel 8 can perform data analysis and report generation functions, and is connected to the side detection camera module 3, the end surface detection camera module 4, the upper surface detection camera module 5, and the performance detection host 6. Through the display panel 8, the operator can monitor and view the images, data, and results of the detection process in real time, providing intuitive feedback and display functions.

[0063] In a preferred embodiment, the device realizes the safety of human-machine separation and upgrades the control of product quality. By printing laser QR codes on products, one code and one object are bound together. The information content includes the whole process information interconnection of material suppliers, process production, and factory inspection.

[0064] Before the product is assembled, the camera module is used to visually inspect the product. The performance testing host 6 automatically performs performance testing on the subjective parts inside the air duct, such as the fan, damper, sensor light, etc. No human intervention is required throughout the process. The separation of man and machine eliminates the risk of electric shock injury during the inspection process.

[0065] Specifically, for visual inspection, after the product is assembled, the appearance, LOGO (logo) and side seams of the product are inspected through a digital high-definition camera. For performance inspection, after the product is assembled, the voltage, current and power of the damper, fan, sensor and other subjective parts in the air duct are inspected through performance inspection equipment.

[0066] In addition, the detection data is interconnected, connecting the factory MES system (manufacturing execution system) with the online detection system to achieve the integration and binding of production information and detection information. The whole process data is visible, the system database performs data backup, and the whole process production data of the product can be queried in the system by scanning the QR code.

[0067] Furthermore, to realize information storage and interconnection, a database is required to store test data. At the same time, production information and test information must be integrated and bound to complete information interconnection and eliminate paper records.

[0068] This device is based on digital information interconnection, combining software systems with detection hardware, integrating and binding production information with detection information to complete information interconnection, realizing automatic detection and separation of man and machine to reduce the labor intensity of employees. It can realize data visualization of the entire production process, effectively reduce the generation and outflow of defective products, and greatly reduce the cost losses caused by defective products.
