[0028] This utility model discloses a testing device for processing air conditioner fan blades. Its working principle is as follows: First, the device is supported by six sets of support legs. Then, the blade to be tested is carefully placed in a rubber mold box to ensure stable and accurate positioning, preventing displacement or damage during transportation. Next, the belt conveyor is activated, and the blade automatically enters the testing area. Then, the infrared sensor in the sensor assembly detects the blade's position, and the system automatically calculates the blade's relative coordinates. Based on the sensor feedback, the control system drives the first and second servo motors to adjust the camera and ultrasonic testing device to the optimal testing angle, ensuring testing accuracy. Then, the camera begins... The system captures high-definition images of the blades. The built-in image processing algorithm analyzes the blade's geometric dimensions, including key parameters such as length, width, and thickness. Then, the ultrasonic testing device emits ultrasonic pulses that penetrate the blade material and receive signals reflected from the blade's internal structure. This allows for the analysis of internal defects such as cracks, delamination, porosity, or inclusions. The built-in software automatically analyzes the images and ultrasonic testing data according to preset standards and parameters, quickly determining whether the blades meet quality requirements. Defective blades are then marked by the system for subsequent processing. Because the mold is made of rubber, the belt will eject the blades during operation, causing them to fall into the receiving box. Defective blades can then be removed.
