Description

Technical Field

[0001] The utility model relates to the field of screening devices, in particular to a sealing ring screening device. Background Art

[0002] In the air-conditioning system, the compressor, condenser, evaporator and other key interface components need to be installed with sealing sheets to prevent air, water or other liquid media from leaking out of the system and to prevent impurities from entering the system. The sealing performance of the sealing ring is very important for preventing the leakage of Freon. The leakage of refrigerant will lead to a decrease in system efficiency. Since the sealing ring has a significant impact on the air-conditioning system, the quality of the sealing ring needs to be tested after the production is completed. Traditionally, the quality control personnel perform manual screening. Due to the small size of the sealing ring, its shape and surface defects are easy to affect the manual judgment. The subjective judgment standards of the screening personnel are different. The same product may get different judgment results when screened at different times or by different operators, thus affecting the overall product quality. It is easy to cause defective products to be misjudged, affecting product quality. At the same time, since manual screening requires a lot of manpower and time, the production efficiency is relatively low. Therefore, in order to solve the above problems, a sealing ring screening device is needed. Utility Model Content
