The robotic arm 1 has multiple degrees of freedom, and a four-axis robotic arm 1, a five-axis robotic arm 1, or a six-axis robotic arm 1 can be selected according to the actual warehouse budget and actual needs. In this embodiment, the robotic arm 1 uses a GCR20 - 1400 robotic arm 1, its effective load is 30 kg, it has 6 rotational degrees of freedom, and the single-arm horizontal working space is 1400 mm.

[0025] Please refer to Figure 2 , the gripping device 3 includes a fixed seat 31 detachably connected to the bottom of the connecting flange 2 by bolts, two telescopic grippers 32 respectively arranged at both ends of the fixed seat 31, and a positioning shaft 33 sleeved on the fixed seat 31 and the telescopic grippers 32; the positioning shaft 33 is used to ensure that the two telescopic grippers 32 do not deviate when telescoping, and the two telescopic grippers 32 are symmetrically arranged along the fixed seat 31; the two telescopic grippers 32 are slidably connected to the fixed seat 31; the fixed seat 31 is fixedly connected to the positioning shaft 33, and the lengths of both ends of the positioning shaft 33 longer than the fixed seat 31 are equal; preferably, in this embodiment, the positioning shaft 33 uses two smooth shafts. Corresponding to the bottom of the fixed seat 31, there are two groups of connecting seats 311 symmetrically arranged along the center of the fixed seat 31. Each group of connecting seats 311 has two, and the connecting seats 311 are fixedly connected to the positioning shaft 33, and one positioning shaft 33 corresponds to one group of connecting seats 311. Please refer to Figure 4 and Figure 5 , by controlling the distance between the two telescopic grippers 32, the gripping device 3 can be applicable to boxes of different sizes, enhancing the versatility of the device;

[0026] Please refer to Figure 2 and Figure 3, the telescopic jaw 32 includes a connecting plate 323, a jaw block 321 provided below the connecting plate 323, and an electric push rod 322 provided above the connecting plate 323. The jaw block 321 is welded to one end of the connecting plate 323 away from the fixed seat 31. One end of the electric push rod 322 is detachably connected to the connecting plate 323 by bolts, and the other end is detachably connected to the fixed seat 31 by bolts;

[0027] Specifically, in this embodiment, the electric push rod 322 is connected to the connecting plate 323 and the fixed seat 31 through lifting lugs.
