System for automatically detecting flaws of dialysis tube

Abstract

The invention relates to a system for automatically detecting flaws of a dialysis tube. The system comprises a transmission rail, a lighting device, a PLC, an image acquisition device, an image processing device and a removing device, wherein the transmission rail is used for placing a to-be-detected dialysis tube; the lighting device is used for providing lighting for the image acquisition device; the image acquisition device is used for acquiring the original image of the dialysis tube and arranged in a position corresponding to the lighting device; the image processing image is used for processing the original image acquired by the imaging acquisition device; the PLC is connected with the image processing device and used for receiving the image processing result; the PLC is connected with the removing device and used for controlling the dialysis tube with the flaws prompted by the processing result of the image processing device; the PLC is connected with the image acquisition device and used for controlling the image acquisition device to acquire the original image on the surface of the dialysis tube. The system has the following beneficial effects: the detection time can be shortened, continuous operation can be conducted and the working efficiency is improved; automatic detection is adopted, the detection standard is uniform and the accuracy is high.

Description

technical field [0001] The invention relates to the field of detection systems, in particular to an automatic detection system for dialysis tube defects. Background technique [0002] At present, the known method of detecting defective products with stains on dialysis tubes is generally a semi-automatic CCD combined with manual inspection. The operation process of this method is to pack the product as a whole and transport it to the manual inspection line. Judging whether it meets the standards specified by the product, if it meets the product, it will be approved, if it does not meet it, it will be taken out and placed in the temporary storage area for defective products, and finally processed in a centralized manner. This approach has three major disadvantages: [0003] 1. The detection efficiency is relatively low, and the detection time for a single product is about 5 seconds. [0004] 2. It is difficult to unify the judgment standards of the inspection. Different insp...

Problems solved by technology

[0003] 1. The detection efficiency is relatively low, and the detection time of a single product is about 5 seconds

[0004] 2. It is difficult to unify the judgment standards of the inspection. Different inspectors may have inconsistent judgments on the same critical product according to their subjective consciousness, and the inspection standards are often affected by the mood of the inspectors.

[0005] 3. Inspectors work for a long time, prone to eye fatigue and reduced judgment, prone to misjudgment and reduced accuracy

Due to the long-term continuous operation, sometimes even the judgment is correct but the placement is wrong. Putting the good product into the defective product area will increase the scrap rate; There will be serious quality problems, and the accuracy of the inspection is often affected by the mood of the inspector
