The WiFi module 24 model is set to TLN13UA06. The WiFi module is also called a serial port Wi-Fi module, which belongs to the Internet of Things transmission layer. Its function is to convert the serial port or TTL level into an embedded module that meets the Wi-Fi wireless network communication standard. It has a built-in wireless network protocol IEEE802.11b.gn protocol stack and a TCP / IP protocol stack. The figure The model of the image recognition module 23 is set to AR0230. The image recognition module is a core component of computer vision technology and is used to understand and interpret image content and convert image data into meaningful information. The ultrasonic sensor model is set to JSN-SR04T. The ultrasonic sensor is a sensor that converts ultrasonic signals into other energy signals (usually electrical signals). Ultrasonic waves are mechanical waves with a vibration frequency higher than 20kHz. They have the characteristics of high frequency, short wavelength, and small diffraction phenomenon, especially good directionality and the ability to become rays and propagate in a directional manner. Ultrasonic waves have a great ability to penetrate liquids and solids, especially in solids that are opaque to sunlight. When ultrasonic waves encounter impurities or interfaces, they will produce significant reflections to form reflected echoes, and when they encounter moving objects, they can produce a Doppler effect.

[0035] The specific implementation method is as follows: when the present invention is used, the feeding conveyor belt 1 transports the casting to the bottom of the bearing base 7, and the ultrasonic sensor detects the position of the casting. At this time, the detection master controller 20 receives a signal and controls the clamping hydraulic cylinder 9 to operate. The clamping hydraulic cylinder 9 pushes out the clamping plate 17, so that the contact rod 18 first moves the casting to one end below the bearing base 7 and clamps it. The anti-slip head 19 can prevent the clamped casting from sliding, thereby ensuring the clamping stability. After clamping, the detection master controller 20 controls the lifting hydraulic cylinder 8 to operate. The operation of the lifting hydraulic cylinder 8 will pull up the two clamping hydraulic cylinders 9, thereby lifting the casting. In this process, the detection master controller 20 synchronously controls the feeding conveyor belt 1 to operate, so that the feeding conveyor belt 1 lifts the casting that is not clamped. One end is pushed forward. During this process, the clamping plate 17 rotates through the steering bearing 15. When the casting stands up, the detection master controller 20 will control the output shaft of the lifting hydraulic cylinder 8 to extend, so as to turn the casting over. When the lifting hydraulic cylinder 8 extends to the limit, the casting is completely placed on the feeding conveyor 1. At this time, the detection master controller 20 detects that the output shaft of the lifting hydraulic cylinder 8 extends to the limit, thereby determining that the casting is turned over. At this time, the clamping hydraulic cylinder 9 is automatically controlled to retract the output shaft, thereby releasing the casting. Then the detection master controller 20 controls the feeding conveyor 1 to run again and transport the next casting for inspection. The whole process is fully automated and does not require manual operation. The standard part appearance image storage 25 can store the standard part appearance image for the image recognition module 23 to retrieve and compare. In use, the image recognition camera 12 can capture the image of the casting on the feeding conveyor belt 1 and send it to the image recognition module 23 for recognition. The image recognition module 23 can recognize the image of the casting on the feeding conveyor belt 1 captured by the image recognition camera 12, and send the recognition result to the detection master controller 20 for processing. When the ultrasonic sensor just detects the casting, the image recognition camera 12 will capture the front image of the casting, and recognize it through the image recognition module 23 in combination with the standard part shape image stored in the standard part shape image memory 25 to determine whether the front of the casting is qualified. When the detection master controller 20 determines that the casting is turned over, the image recognition camera 12 will capture the back image of the casting, and recognize it through the image recognition module 23 in combination with the standard part shape image The image of the standard part shape stored in the memory 25 is identified to determine whether the back of the casting is qualified. When the image recognition camera 12 takes a picture of the casting, the detection master controller 20 controls the lighting LED lamp 14 to light up, so that the image recognition camera 12 can clearly take a picture of the casting. If the image recognition shows that both the front and back sides are qualified, the detection master controller 20 controls the feeding conveyor belt 1 to transport the next casting for inspection. If the image recognition shows that one of the front and back sides is unqualified or both are unqualified, the detection master controller 20 stops the feeding conveyor belt 1 and controls the flashing warning light 21 to light up to remind the staff that there is a problem with the casting. At the same time, the detection master controller 20 contacts the staff's mobile phone terminal 26 through the WiFi module 24 to inform the staff that there is a problem with the casting and that they need to go there for processing.This makes the present invention highly automated, and can detect castings directly through image recognition, with high detection efficiency and high detection accuracy, while greatly reducing labor costs, making the actual use effect of the present invention better.
