[0034] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the loading and unloading mechanism 100 includes a vertical adjustment portion 30;

[0035] The vertical adjustment part 30 includes a first frame 31, a vertical guide rail 32 and a vertical screw rod 33; the vertical guide rail 32 is connected to the material picking device 20 and the first frame 31, so that the material picking device 20 can move in the vertical direction relative to the first frame 31; the vertical screw rod 33 is connected to the material picking device 20 and the first frame 31, and the material picking device 20 is driven to move along the vertical guide rail 32 by the rotation of the vertical screw rod 33, so as to realize the adjustment of the vertical movement of the material picking part 24; the loading and unloading mechanism 100 includes a second driving part 34, and the second driving part 34 is installed on the first frame 31, and the output shaft of the second driving part 34 is connected to the vertical screw rod 33, so as to realize the automatic adjustment of the vertical lifting of the material picking part 24 and improve the working efficiency of the material picking part 24.
