At the same time, the two detectors 7 reciprocate linearly inside the two mobile frame assemblies 6 respectively. When the aluminum veneer is transmitted to the middle of the two clamping frames 4, the flipping assembly 5 is controlled to make the two clamping frames 4 approach each other to clamp the aluminum veneer, and the flipping assembly 5 is used to flip the clamped aluminum veneer 180 degrees, and then the flipping assembly 5 is controlled to make the two clamping frames 4 move away from each other to release the clamping of the aluminum veneer. At this time, the aluminum veneer will fall onto the conveyor belt 3 again, and then pass under a group of mobile frame assemblies 6. The two detectors 7 will detect both sides of the aluminum veneer. If there are defective products, when the aluminum veneer is transmitted to the position of the push plate 10, the hydraulic rod 9 will immediately start to drive the push plate 10 to push the aluminum veneer off the conveyor belt 3.
