Above the material-retrieving mechanism is a box-feeding stack 6 composed of multiple stacked square boxes 60. The indexing box 20 is positioned along a first direction (… Figure 1 A swing output shaft 200 is provided on one side (as shown in the Y direction). The swing arm assembly extends along the first direction, and the connecting rod 21 extends along the second direction (as shown in the Y direction). Figure 1 Extending in the Z direction (as shown), and respectively located on both sides of the swing arm assembly along the first direction. A suction nozzle 22 is provided at the top of the connecting rod 21. The swing arm assembly is connected to the swing output shaft 200 and the connecting rod 21 respectively, and is used to drive the swing arm assembly to swing circumferentially through the swing output shaft 200, thereby driving the connecting rod 21 to move up and down relative to the indexing box 20 in the second direction, adsorbing and transferring the square box 60 from the square box feeding stack 6, thereby improving the material picking efficiency of the picking mechanism. The first direction is perpendicular to the second direction, and the circumferential direction surrounds the first direction.

[0031] In some embodiments, reference Figures 1 to 3 The swing arm assembly includes a first connecting arm 24, a second connecting arm 25, a fixing block 26, a rotating bearing 27, and a support base 28. Synchronous bearings 202 are spaced apart below the swing output shaft 200, and the first connecting arm 24 is positioned along a third direction (…). Figure 1 One end of the first connecting arm 25 (shown in the X direction) is fixedly connected to the swing output shaft 200, and the other end is rotatably connected to the fixed block 26 via a rotating bearing 27.
