Specifically, the four clamping rods respectively extend downward into the X, Y, Z and W spaces around the mobile phones, and then the assembly 6111 is actuated, and the assembly 6111 drives the four clamping rods to move close to each other along the radial direction of the fixed disc 612 through the connecting rod 6112, and the clamping rods simultaneously clamp multiple mobile phones at one time. When the four clamping rods move close to each other and clamp multiple mobile phones, the side surface of the clamping rod cooperates with the side surface of the mobile phone, which promotes the mobile phones to rotate in the circumferential direction, so that the projection of the upper and lower adjacent mobile phones in the up-down direction increases, so that each mobile phone can avoid the four supporting pieces 5036b around the mobile phone, and each mobile phone can avoid the supporting pieces 5036b to leave the buffer module 500 from the top of the buffer module 500.

[0051] When there are many mobile phones in the buffer module 500, the second clamping jaw 6122 grabs multiple mobile phones at one time and puts them into the storage bin 700 on one side. Specifically, after the second clamping jaw 6122 grabs multiple mobile phones from the buffer module 500 at one time, the mechanical arm is lifted, and the rotating arm 607 of the mechanical arm is rotated, and then the multiple mobile phones are transferred to the storage bin 700, and then the multiple mobile phones enter the storage bin 700 from the opening on one side of the storage bin 700. Under the support of the blocking strips 701, the multiple mobile phones are respectively supported on the multiple blocking strips 701.
