Description

Technical Field

[0001] This invention relates to the field of surface defect detection of ceramic diaphragms, and particularly to a multi-stage progressive online detection device and method for intermittent flipping of ceramic diaphragms. Background Technology

[0002] Ceramic membrane panels are made from inorganic ceramic materials through a special process and are now widely used in seawater desalination, wastewater treatment, and other fields. However, due to the brittleness of ceramic membrane panels, surface damage may occur during actual production. If surface defects of ceramic membrane panels can be detected in time during the production stage, it will avoid the need to continue processing unqualified products, reduce processing costs, and minimize economic losses.

[0003] In 2017, Zhang Hengwang et al. from Jiangsu Xinshi High Temperature Materials Co., Ltd. proposed a macroscopic defect detection device for flat ceramic membranes (authorization announcement number: CN206479516U). This device achieves automated defect detection of ceramic membrane plates by setting a detection module at the front end of the main conveyor belt. However, this device only realizes the single-sided detection of defects in ceramic templates and does not involve a method for double-sided detection of defects in ceramic templates.

[0004] Since defects can occur on both the top and bottom surfaces of ceramic membrane panels, a double-sided defect detection method must be considered to avoid quality problems caused by omissions or misjudgments due to single-sided inspection. Currently, commonly used detection devices for double-sided defect detection of ceramic membrane panels are mainly divided into three categories: The first type refers to a double-sided inspection device where the workpiece remains stationary, and a set of inspection modules is installed on each of its two sides. Since there is limited literature on the visual inspection of ceramic films, a broader search was conducted for similar flat panel patents. In 2021, Nie Zhihua et al. from the Jiangxi Provincial Institute of Intelligent Industry Technology Innovation proposed a device for detecting defects on the upper and lower surfaces of a flat panel (authorization announcement number: CN216411100U). This device achieves automated double-sided defect detection by setting inspection modules at both ends of the inspection space reserved in the conveyor device. However, dust and other debris on the lower surface of the workpiece continuously fall due to production line vibrations, inevitably reducing the lens clarity of the lower inspection camera and thus affecting the inspection quality. Therefore, this type of device suffers from the problem of easy contamination of the lower camera lens and is not suitable for automated production line inspection.

[0005] The second type refers to double-sided inspection devices where the workpiece is flipped, and only one inspection module is equipped on one side of the workpiece. In 2021, Song Heshu of Hansong Precision Parts (Kunshan) Co., Ltd. proposed a PCB board defect inspection platform based on vision recognition (authorization announcement number: CN217212329U). This device flips the workpiece using a flipping mechanism, while simultaneously using a lifting platform to raise and lower the flipping mechanism, thus achieving double-sided defect inspection of the workpiece through flipping. However, the flipping mechanism and the inspection device are located at the same workstation. When one workpiece is being inspected, other workpieces must wait, making it difficult to ensure the continuity of the production process. Although this type of method is suitable for automated inspection on production lines, it still suffers from the problem of long waiting times for workpieces to be inspected and discontinuous production processes.

[0006] The third type is based on the second method, involving flipping the workpiece and equipping one side of it with two sets of detection modules for a double-sided inspection device. In 2022, Dou Min of Jiangsu Xinyuan Electric Manufacturing Co., Ltd. proposed an automatic surface defect detection device for cold-rolled steel plates (Publication No.: CN115684187A). This device lifts and flips the steel plate using a flipping block and a clamping plate, and adopts a separate arrangement of the flipping device and the detection device to achieve simultaneous detection and flipping. However, because the flipping block and the clamping plate of this device are in series, it can only flip one workpiece at a time, and the waiting time for the workpiece to be flipped is relatively long.

[0007] Based on the aforementioned issues, in 2022, Fan Zehang et al. from Hangzhou Hanzhentu New Technology Co., Ltd. proposed a ceramic substrate inspection device (Publication No.: CN115338145A). This device achieves the function of simultaneously flipping multiple workpieces by using a servo motor to rotate a flexible turntable. However, because controlling the start-stop frequency and angle of the servo motor requires a complex control system and high control precision, it is difficult to flexibly adapt to different production cycles, and relying solely on the flexible turntable to hold the workpiece makes it difficult to guarantee the stability of workpiece flipping.

[0008] In summary, the third type of method achieves simultaneous detection and multi-workpiece flipping based on the second type of method. However, it still faces the problem of difficulty in flexibly adapting to different production cycles when facing the actual production needs of multi-variety small-batch production. Summary of the Invention
