[0065] Reference Figure 8 and Fig. 9The second sliding drive device 10 is precisely designed to control the precise and flexible displacement of the transport device 9 in the horizontal direction, ensuring that the transport device 9 can slide to the desired position according to the predetermined distance. At the same time, the rotation drive device 6 is responsible for driving the rotating seat 5 to rotate to a precise angle. This action is closely coordinated with the sliding action to form an efficient coordination mechanism.

[0066] Reference Figure 5 and Fig. 9 During the operation, first, the rotary drive device 6 accurately controls the rotary seat 5 to rotate to an optimized angle, which is accurately calculated based on the specific requirements of the handling task and the layout of the intelligent storage 14. Then, the second sliding drive device 10 is immediately started to drive the horizontal moving frame 91 of the handling device 9 and the fork 92 thereon to slide smoothly and accurately to the target position along the horizontal direction. The two actions of rotation and sliding are performed alternately, forming a continuous and smooth handling process, which greatly enhances the position adjustment capability of the handling device 9.

[0067] Reference Figure 1 and Fig. 9 Through this alternating execution, the handling device 9 can easily and accurately deliver the fork 92 to the designated placement area 141 of the intelligent storage bin 14, and can also efficiently and safely move the fork 92 out of the placement area 141. This process not only significantly reduces the demand for space between the automatic loading and unloading device 1 and the intelligent buffer for feeding operations, effectively reduces the width of the flexible intelligent production line, thereby reducing the overall floor space, but also greatly improves the accuracy and efficiency of workpiece handling, providing a strong guarantee for the flexibility and efficiency of the production line.

[0068] Reference Figure 1, the feeding equipment also includes a visual inspection device, which includes a high-precision camera, a light source system, image processing and analysis software, and an output and feedback device, wherein the high-precision camera: as the core component of visual inspection, the high-precision camera can capture and generate a clear image of the inspected workpiece. These cameras usually have characteristics such as high resolution, high sensitivity and low distortion to ensure the accuracy and reliability of the image; the light source system can adjust the brightness, color and direction according to the inspection requirements, reduce external light interference, highlight the workpiece features, and improve the inspection accuracy; the image processing and analysis software is the "brain" of the visual inspection device, which is responsible for receiving the image data collected by the camera, processing and analyzing the image through a series of complex algorithms, extracting the key feature information of the workpiece, such as size, shape, position, etc., and comparing it with the preset standard parameters to determine whether the workpiece is qualified; when the image processing and analysis software completes the inspection task, the visual inspection device will present the inspection results through the output device (such as display screen, indicator light, etc.), and feedback the relevant information to the control system. If the workpiece is unqualified, the control system will take corresponding processing measures according to the feedback information, such as stopping feeding and issuing an alarm.

[0069] During the feeding process, the visual inspection device first takes a photo or video of the workpiece to obtain its image information. Then, the image is preprocessed (such as denoising, contrast enhancement, etc.) using image processing and analysis software to improve image quality. Next, the software will extract and identify features from the processed image and compare it with the preset standard parameters. Finally, the workpiece is judged to be qualified based on the comparison results, and the test results are fed back to the control system.

[0070] Reference Figure 4 The feeding equipment also includes a control system, which can automatically adjust and control the motion trajectory, speed and positioning accuracy of the sliding seat 3, rotating seat 5, lifting seat 7 and handling device 9 according to the preset production plan or real-time production demand. The control system includes a central processing unit, multiple sensors and actuators. The central processing unit is preset with the position parameters and processing parameters of each machine. The status and position of each device are monitored in real time through sensors, and instructions are output to the actuator to achieve automatic control. The control system also has self-detection and fault alarm functions to ensure the normal operation of the production line.

[0071] The implementation principle of this embodiment is as follows: the flexible intelligent production line of this application has efficient material loading capability, significantly improves production efficiency and automation level, reduces operation difficulty and labor cost. The control system can adjust the position of each component in real time, realizes accurate workpiece transmission, and improves the automation level of the overall production line.

[0072] Example 2 The main difference between this embodiment and the above embodiment is that a feeding method based on a flexible intelligent production line is specifically described, including the following steps: Step 1: Using an AGV automatic guided vehicle, according to a preset path or real-time instructions, the workpiece to be processed is automatically transferred from the outside to the automatic loading and unloading device 1; Step 2: The automatic loading and unloading device 1 accurately delivers the workpiece to be processed to the feeding device or directly to the processing device 15 for preliminary processing; Step 3: After receiving the workpiece from the automatic loading and unloading device 1, the feeding device first safely transfers the workpiece to the intelligent storage 14 for temporary storage through the precise cooperation of its integrated sliding seat 3, rotating seat 5, lifting seat 7 and handling device 9. Then, the feeding device intelligently identifies and takes out the next workpiece to be processed from the intelligent storage 14, and through optimized path planning, efficiently and accurately transfers the workpiece to the processing equipment 15 for further processing; Step 4: When the processing device 15 completes the processing task of the workpiece, the feeding device starts again, takes out the processed workpiece from the processing device 15, and safely transfers it back to the intelligent storage library 14 for storage; at the same time, the feeding device continues to take out the next workpiece to be processed from the intelligent storage library 14, and transfers it to the processing device 15 again for cyclic processing; Step 5: Repeat steps 3 to 4 to form a closed-loop automated production process. In this process, the feeding equipment, processing equipment 15 and intelligent storage 14 work closely together to achieve automatic storage, retrieval, processing and re-storage of workpieces, ensuring the continuous and stable operation of the production line; Step 6: After completing the processing and storage tasks of all workpieces, the feeding device sequentially transfers the processed workpieces in the intelligent storage 14 to the automatic loading and unloading device 1. After receiving the workpieces, the automatic loading and unloading device 1 again transfers the finished workpieces to the AGV automatic guided vehicle through its internal device. Finally, using the automatic navigation and transportation capabilities of the AGV, the processed workpieces are accurately transferred to the designated target area or the next production link, completing the finished product output and subsequent processing of the entire production process.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
