[0035] The working principle of the multi-segment transfer mechanism disclosed in this embodiment of the invention is as follows: The rodless cylinder 101 drives the inner frame assembly 4 and the lifting mechanism 3, outer frame assembly 5 and clamping mechanism 2 installed on the inner frame assembly 4 to move synchronously above the material to be transferred. The first-stage lifting cylinder 301 and the second-stage lifting cylinder 302 both extend with air intake, driving the outer frame assembly 5 and clamping mechanism 2 to move downward until the two clamping units in the clamping mechanism 2 are located on both sides of the material. The first-stage lifting cylinder 301 and the second-stage lifting cylinder 302 both stop running. Then, the clamping cylinder 2011 drives the bearing assembly 202 and the clamping component 203 to move closer to each other to effectively clamp the material. After clamping, the material is transferred to the required position through the combined action of the rodless cylinder 101, the first-stage lifting cylinder 301 and the second-stage lifting cylinder 302. After moving to the position, the clamping cylinder 2011 extends outward to release the clamped material.
