Description

Technical Field

[0001] The invention relates to the technical field of separation membrane detection equipment, and in particular to a separation membrane product defect detection method based on artificial vision. Background Art

[0002] Separation membrane is a material commonly used in engineering and environmental fields. It is a thin film material used to separate or isolate different substances, phases or environments. These membranes are usually made of polymers, metals or other specific materials, and have specific separation, filtration or protection functions. Separation membranes need to be inspected for defects after production, because during the production process, the separation membrane may have different thicknesses or holes.

[0003] However, the existing separation membrane defect detection method has the following problems: although the existing separation membrane defect detection equipment can find the separation membrane defect location, the automation level is low and there may be omissions in the search process, and the found location often needs to be manually marked and then processed by specialized staff, resulting in low repair efficiency. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Summary of the invention

[0004] The purpose of the present invention is to provide a separation membrane product defect detection method based on artificial vision, which solves the technical problem that although the existing separation membrane defect detection equipment can find the separation membrane defect position, it has a low degree of automation and may miss something during the search process, and the found position often needs to be manually marked and then processed by specialized staff, resulting in low repair efficiency.

[0005] To achieve the above object, the present invention provides the following technical solution: a separation membrane product defect detection method based on artificial vision, comprising the following steps:

[0006] Step 1: Preparation for putting separation membrane products on shelves:

[0007] Step 2: Transverse guide detection and processing of the separation membrane;

[0008] Step 3: Automated light detection and processing of the separation membrane;

[0009] Step 4: Automated labeling of separation membrane detection;

[0010] Step 5: Subsequent repair of the separation membrane;

[0011] Through the above five steps, the separation membrane is sequentially put on the rack, laterally guided, light-detected, defect-marked, and subsequently repaired, so as to achieve rapid and efficient detection and treatment of separation membrane defects. The defect detection of the separation membrane product defect detection method uses a defect detection device as an operation carrier;

[0012] The defect detection equipment includes a detection platform, a mounting frame, a transverse guide component, a light detection component and a movable marking component. The mounting frame is divided into two groups and symmetrically installed at the two ends of the detection platform.

[0015] The mobile marking assembly includes a servo motor, a screw, a slider, an infrared receiver, a motor, a driving gear, a driven ring, a nozzle, an infusion tube, a pump body and a liquid storage container. A guide groove is provided on the mounting plate. The servo motor is installed at one end of the guide groove and the power output end is connected to the screw. The screw is rotatably arranged in the guide groove. The slider is embedded in the screw and the bottom is slidably arranged in the guide groove.
