[0043] This utility model relates to a coating roller surface grooving detection device, which can complete five steps: coating roller fixing, surface cleaning, image acquisition, data processing, and automatic adjustment. It is applicable to coating roller specifications: length 800-1600mm, diameter 200-300mm; the measuring arm length is adjustable from 800-1215mm; the measurement accuracy for coating roller grooving depth is ≤±0.01mm; it has comprehensive reporting functions, capable of generating and exporting reports by shift, time period, and roller number; it saves inspection records and images for up to one year, which can be migrated to other storage media with one click; the design resolution is 1µm in both the width and length directions.

[0044] The specific steps of the coating roller surface groove detection device of this utility model are as follows:

[0045] First, fix the coating roller to be tested on the grinding machine, ensuring its axis is aligned with the center of the grinding machine chuck. Then, use a clamp or chuck to fix the coating roller, ensuring it will not shift or vibrate during the testing process. Start the testing device and check whether each module (such as sensor, camera, motor, etc.) is working properly. Set the testing parameters, including the standard value of the groove depth, the testing range, and the rotation speed. Move the testing device to one end of the coating roller, and the rotary drive motor 21 drives the rocker arm 32 to rotate, rotating the measuring arm above the coating roller. Start the first cylinder 312 and the second cylinder 313 to open the split left cover 314 and right cover 315 to both sides, and start the air nozzle 318 to clean the surface of the coating roller with air jets, removing dust and impurities to ensure the surface of the coating roller is clean and to avoid impurities interfering with the testing results. Rotate the coating roller at a constant speed, while the displacement slide moves the measuring arm along the coating roller axis to ensure that the testing module can fully scan the surface of the coating roller. The telecentric light source 35 of the testing module provides uniform light. Under suitable lighting conditions, ensuring clear visibility of the groove features on the coating roller surface, the telecentric lens 34 works in conjunction with the camera 33. The camera 33 scans and inspects the coating roller surface along a spiral trajectory, performing high-precision imaging to capture the microscopic features of the grooves. The camera 33 transmits the acquired image data to the data processing module. The data processing module receives the image data from the camera, analyzes the groove depth using a built-in algorithm, compares the measurement results with preset standard values, determines whether the groove depth is qualified, generates an inspection report, and records the groove depth data for each inspection point. The inspection results are displayed in real time on the control panel, which operators can view at any time. If the detected groove depth is unqualified, the system will issue an alarm signal to prompt the operator to take action. When all inspection points are qualified, the operator can further process or release the coating roller according to the inspection report. After the inspection is completed, the inspection module is turned off, the displacement slide and measuring arm are reset to their initial positions, the coating roller is removed, and the entire inspection process is completed.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
