Product Description

The Serve valve CCD Automatic visual inspection machine is mainly used for visual inspection of external defects in various types of gate valves. It adopts a PLC + touch screen control and display mode, uses imported vision sensors for detection, and features rotary cyclic testing. It is quick and easy to operate, with a high degree of automation. It is suitable for external inspection of multiple types of gate valves and has automatic prompts and alarm functions during operation. Since its use, it has significantly improved the automation level and inspection efficiency of gate valve external testing in China.

Inspection Process and Results

Compared to traditional manual inspection, the Serve valve CCD Automatic visual inspection machine offers higher inspection efficiency and accuracy, reduces human error, and can replace manual vision in hazardous environments unsuitable for manual operation, thus achieving automated and intelligent production processes. Frist, the Serve valve is placed on the inspection platform. Then,The system automatically rotates and captures images from multiple angles, Final , analyzing dimensional deviations using algorithms. If the shell wall thickness or valve stem diameter exceeds the standard range, the system immediately determines it as a defective product and triggers an alarm. Compared to traditional manual inspection, this system increases inspection efficiency several times over while reducing the false judgment rate.

Performance Testing Standards

The Serve valve CCD Automatic visual inspection machine can effectively improve the quality control level in the production process of gate valves, promptly identify and eliminate unqualified products, and ensure market supply security.

Inspection items	Inspection content	Technical Requirements Standards
Power supply detection	Main power supply	Check if the wiring to each terminal is secure and if the wiring number tube markings are correct.
Power supply detection	Start-up circuit	Can the machine start normally?
Machine installation and testing	Machine foot pad installation stability test	Are the foot pads raised and supported on the ground?
Machine installation and testing	Machine foot pad installation stability test	Are the casters suspended in the air?
	Running speed	60-80 per minute.
performance	pass rate	The pass rate for qualified products is 99.0%. Note: False rejection is allowed (OK products are judged as NG products), with a false rejection rate of less than 5%, which varies depending on the specific defect.
	Camera lifespan	The lifespan of a camera under normal use is more than one year.
	Data statistics	Real-time statistical detection data
	Equipment control performance	(1) When the product size or appearance is found to be NG, it is directly discharged without alarming or stopping the machine; (2) When a product is continuously NG (the number of consecutive NGs can be set by the program), the equipment needs to alarm and stop (red light and alarm sound). (3) If there is a material shortage for 1 consecutive minute (time limit adjustable) (no material passes under the CCD), the equipment should alarm and stop (red light and alarm sound).
