Defect detection device for evaporator pipe fitting and production system of pipe winding type evaporator

Abstract

The invention provides a defect detection device for an evaporator pipe fitting and a production system of a pipe winding type evaporator. The defect detection device for the evaporator pipe fitting comprises a straightening machine, a defect detector and a reminding device, wherein the straightening machine is used for carrying out straightening treatment on the evaporator pipe fitting; the defect detector is used for carrying out defect detection on the evaporator pipe fitting which is subjected to the straightening treatment by the straightening machine; and the reminding device is connected to the defect detector and is used for reminding a user of a detection result of the evaporator pipe fitting, which is detected by the defect detector. According to the technical scheme, when an evaporator is produced in a pipe winding manner, the defects of the evaporator pipe fitting are detected before the evaporator pipe fitting is wound on a liner of a refrigerator, and an aluminum pipe with the defects can be effectively prevented from being used on the evaporator of a refrigerator or a freezer, so that the quality of a pipe winding type evaporator product is extremely improved; and the problem that the pipe fitting with the leakage defects is used on the evaporator or refrigerator product with the pipe winding type evaporator so that the refrigeration is not realized can be effectively prevented.

Description

Technical field [0001] The present invention relates to the technical field of evaporators, in particular to a defect detection device for evaporator pipes and a production system of a wound-tube evaporator. Background technique [0002] At present, aluminum tubes have been widely used in the manufacture of refrigerator evaporators due to the advantages of low cost, high thermal conductivity, and good processing and formability. However, due to the impurities in the material of the aluminum tube itself and the processing technology problems of hot extrusion, the finished aluminum tube may have defects such as cracks, unperforated needle holes, slag inclusions, bubbles, delamination, and trauma. [0003] When the evaporator of a refrigerator or a freezer is made by the pipe winding method, the aluminum tube coil is directly wound on the refrigerator box after being straightened by a straightening machine. This method causes cracks, needle holes, trauma, slag inclusion, and Defectiv...

AI Technical Summary

Problems solved by technology

However, due to the impurities in the material of the aluminum tube itself and the processing technology of hot extrusion, the finished aluminum tube will have defects such as cracks, unperforated pinholes, slag inclusions, air bubbles, delamination, and trauma.

[0003] When the evaporator of the refrigerator or freezer is made by winding the tube, the aluminum tube coil is straightened by a straightening machine and then directly wound on the tank of the refrigerator. This method causes cracks, pinholes, trauma, slag inclusions, Aluminum tubes with defects such as air bubbles or traumatic defects in the production process cannot be effectively detected and used directly on the product, which will lead to internal leakage of the evaporator and cause the refrigerator to not cool
