Medical rubber plug is a component used for medical devices, which is usually used to close or block pipes or passages. They are usually made of soft materials such as rubber or silicone, which have good sealing properties and can prevent liquid or gas leakage. Medical rubber plugs are widely used in medical equipment, surgical instruments or laboratory equipment to control the flow of liquid or protect substances in containers. These rubber plugs are usually easy to install and remove, and can be designed in various shapes and sizes to meet different application needs. 

 There may be some defects in medical rubber plugs that may affect their function or safety. Sometimes the sealing performance of medical rubber plugs is not ideal; low-quality or non-durable materials lead to wear, deformation or cracking; inappropriate size or improper design; incompatible with specific chemicals, resulting in corrosion or degeneration of the material, thus affecting its performance. 

   In order to solve the problem of defect detection in different regions, a positive appearance defect detection algorithm of cloud disk visual detection equipment is provided. The positive light defect detection algorithm is mainly used to detect the surface defects of medical rubber plugs. It mainly checks the appearance defects such as dirt, deformation, flying edge, material shortage, leakage, aluminum chip residue, etc. of the lid.
