When the wheel passes through the front / rear code reading device of MD860, determine whether it is the first, middle and last piece that needs to be inspected based on the code reading time of the wheel before the machining production line. If it is a random inspection wheel, a signal is given to the roller system, and the roller's material separation and pushing system pushes the wheel to the three-coordinate automatic loading system for inspection; if it is not a random inspection wheel, it is transferred downward in the normal logistics mode.
[0036] 3. Adjust the production status of the preceding machining production line according to the test results (quality adjustment, normal batch production, etc.).

Unqualified products shall be pushed out of the material channel using the QR code reader (a quality traceability containment interface is reserved, and the cancellation of the quality mark can be automatic or manual).
[0040] 7. The random inspection can be set to pause and start functions. After clicking pause, the random inspection function will no longer be enabled.
[0041] Working principle of this utility model:
[0042] Through the upgrade and transformation of the three-coordinate robot 4 feeding automation system, each machining production line is equipped with a QR code reader to ensure that the incoming products have a unique traceability QR code, and automatic sampling and material separation are carried out according to the pre-set sampling rules. The basic information and processing information of the wheel type are transmitted to the robot feeding system and the three-coordinate automatic detection system based on the production status information.
