Existing defect-detection equipment.

Name		Performance
Packaging defect-detection equipment	Function	color detection, window or insert detection, carton ejection, tilt, double-feed monitoring and glue line detection of mechanical product packaging.
	Trait	remote control, off-site monitoring, and tracking. ineffective for metal or special transparent packing.
LYNX Industrial vision system	Function	detect and analyze missing and damaged parts and assembly errors.
	Trait	System hardware can be controlled by the central terminal, which can adapt to various working environments and cover the detection amount of size and size. It is easy to operate, fully closed, a multi-detection system with data.
IRNDT infrared thermal imaging testing	Function	The defect image is displayed, and the feature is evaluated by heating the tested parts and analyzing the defect position with abnormal internal temperature.
	Trait	The equipment has the characteristics of the non-contact, large area, fast speed and visual display it has a poor effect on metal parts with a large amount of heat deformation.
Smart U32 Ultrasonic scanning detector	Function	This is used to perform ultrasonic phased array probe, sound beam control, and dynamic focusing technology to realize scanning and imaging detection of composite and metallic materials.
	Trait	Coupling stability, automatic measurement, and accurate verification. However, it is not good for the detection of large-size parts and non-metal parts.
Parts appearance optical detection equipment	Function	This is used to detect parts with diameters ranging from 65 mm to 110 mm, such as sprockets, stators, and rotors. It can also detect breakage, bumps, and cracks.
	Trait	TPros: non-destructive testing, multi-angle identification, fast detection speed, high precision, stable performance, and accurate data statistics function.
Turbine detection system	Function	The defect of the shallow surface of metal parts is detected through the analysis and treatment of the eddy current. It is suitable for defect detection of conductive materials.
	Trait	Eddy current testing is only applicable to conductive materials. It can only detect defects on the surface or near the surface layer. It is not conducive for use in components with complicated shapes.
Sealing detection equipment	Function	It collects and analyzes the images of the seal ring directly above, sides, and bottom and extracts the surface scratches and bubble defects of the seal ring.
	Trait	The equipment can set the number of test stations, adjust the test sequence and methods at will, and support the detection of all product models. The detection speed is slow, which reduces the production tempo along the pipeline.
3D Visual measuring equipment	Function	It has the functions of edge extraction, contour degree and other 2D and 3D form tolerance calculation, 3D digital model comparison, and heat map display.
	Trait	The device can only detect non-transparent products, and the measuring effect is insufficient when the running speed is over 400 mm/s.
Inkjet detector	Function	It can detect defects in mechanical parts without and incomplete codes, indented characters, and offset position of the code.
	Trait	The device consists of a code detection unit, man-machine interface, and stripper. However, it is ineffective in detecting parts with greasy surfaces.
