[0041] Working principle: The technician places the product above the fixture 16. When the through-beam photoelectric sensor 17 detects the product, the lifting cylinder at the bottom of the fixture 16 lifts the fixture 16. At the same time, the hydraulic cylinder 34 is started, causing the vertical sliding plate 33 to slide along both sides of the Z-axis 32 until the flipping mechanism moves down to the material taking position.

After the flipping is completed, the second driven wheel 23 is started to make the vertical sliding plate 33 slide downward to the material discharging position. At this time, the gripper cylinder 11 controls the auxiliary gripper to loosen. The second rotating motor 20 is started to make the profiling gripper 14 release the product. Finally, the second driven wheel 23 is started to make the flipping mechanism rise to the rotating position.
