[0043] The model of the single-chip microcomputer is set as M68HC16. A single-chip microcomputer is an integrated circuit chip. It is a small and complete microcomputer system formed by integrating a central processing unit CPU with data processing capabilities, a random access memory RAM, a read-only memory ROM, multiple I / O ports, an interrupt system, a timer / counter, etc. onto a silicon chip using very large scale integration technology. The model of the WiFi module 24 is set as TLN13UA06. The WiFi module, also known as a serial port Wi-Fi module, belongs to the Internet of Things transmission layer. Its function is to convert a serial port or TTL level into an embedded module that conforms to the Wi-Fi wireless network communication standard, and it has a built-in wireless network protocol IEEE802.11b.g.n protocol stack and a TCP / IP protocol stack. The model of the image recognition module 23 is set as AR0230. The image recognition module is the core component of computer vision technology, used to understand and interpret the content of images and convert image data into meaningful information. The model of the ultrasonic sensor is set as JSN-SR04T. An 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 20 kHz. They have the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directivity, and can be emitted as rays for directional propagation. Ultrasonic waves have a great penetration ability for liquids and solids. Especially in opaque solids, when ultrasonic waves encounter impurities or interfaces, they will produce significant reflections to form reflected echoes, and they can produce the Doppler effect when encountering moving objects.

[0044] The implementation method is specifically as follows: When using the present invention, the feeding conveyor belt 1 transports the casting under the bearing base 7. The ultrasonic sensor will detect the position of the casting. At this time, the detection master controller 20 will receive the signal and control the clamping hydraulic cylinder 9 to operate. The clamping hydraulic cylinder 9 will push out the clamping plate 17, so that the contact rod 18 clamps the casting at one end under the bearing base 7 first. The anti-slip head 19 can prevent the clamped casting from sliding and ensure 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. During this process, the detection master controller 20 synchronously controls the operation of the feeding conveyor belt 1, so that the feeding conveyor belt 1 advances the unclamped end of the casting 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, thereby turning the casting over. When the output shaft of the lifting hydraulic cylinder 8 extends to the limit, the casting is completely placed on the feeding conveyor belt 1. At this time, the detection master controller 20 detects that the output shaft of the lifting hydraulic cylinder 8 extends to the limit, and thus determines that the casting turning-over is completed. At this time, the detection master controller 20 automatically controls the clamping hydraulic cylinder 9 to retract the output shaft, thereby loosening the casting. Then the detection master controller 20 controls the feeding conveyor belt 1 to operate again to convey the next casting for detection. The whole process is completely automated without manual operation. The standard part shape image memory 25 can store the standard part shape image for the image recognition module 23 to retrieve and compare. The image recognition camera 12 can take pictures of the casting image 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 casting image on the feeding conveyor belt 1 taken 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 take a front image of the casting and perform recognition 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 turning-over is completed, the image recognition camera 12 will take a back image of the casting and perform recognition 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 back of the casting is qualified. When the image recognition camera 12 takes pictures of the casting image, the detection master controller 20 will control the lighting LED lamp 14 to light up to facilitate the image recognition camera 12 to clearly take pictures of the casting. If the front and back of the image recognition are both qualified, the detection master controller 20 controls the feeding conveyor belt 1 to convey the next casting for detection. If one or both of the front and back of the image recognition are unqualified, the detection master controller 20 stops the feeding conveyor belt 1 and controls the flashing warning lamp 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 mobile phone 26 through the WiFi module 24 to notify the staff that there is a problem with the casting and they need to go to deal with it.This makes the automation degree of the present invention high. The casting is directly detected through image recognition, with high detection efficiency and high detection accuracy. At the same time, the labor cost is greatly reduced, making the actual use effect of the present invention better.
