The tray lifting driving member 1613 synchronously drives the two lifting platforms 1612 to move in opposite directions in the up and down directions, so that when one of the lifting platforms 1612 is lifted up, the other lifting platform 1612 is synchronously moved down.

[0058] The tray lifting drive component 1613 includes a driving motor and a synchronous transmission component. The synchronous transmission component of this embodiment adopts a synchronous belt mechanism, and the synchronous belt is wound around two synchronous pulleys arranged in an upper and lower position. The belt surfaces on both sides of the synchronous belt extend in the upper and lower directions and are respectively connected to the two lifting platforms 1612 in a transmission manner. When the driving motor drives the synchronous pulley to rotate, the belt surfaces on both sides of the synchronous belt drive the two lifting platforms 1612 to move in opposite directions in the upper and lower directions. In some other embodiments, the synchronous transmission component can also adopt other transmission methods such as chain transmission, gear transmission or worm gear transmission.

[0059] The tray moving component 1611 includes a tray moving suction cup, a tray moving cylinder and a suction cup cylinder which are arranged perpendicular to each other. The tray moving suction cup is arranged above the two lifting platforms 1612. The tray moving cylinder is arranged along the connecting direction of the two lifting platforms 1612, and the suction cup cylinder is arranged along the up-down direction. The tray moving suction cup is driven by the tray moving cylinder and the suction cup cylinder to move horizontally and vertically, so as to move the product tray in coordination with its adsorption action.

[0060] The material moving mechanism 1620 includes: a material moving claw and a material feeding and moving claw component, and the material feeding and moving claw component is configured to drive the material moving claw to move between the tray mechanism 1610 and the welding fixture 111, or between the tray mechanism 1610 and the assembly fixture 411.

[0061] In this embodiment, the feeding and shifting claw member and the material handling and transferring member 1520 both use a four-axis robot. The material handling claw 1510 is arranged at the working end of the material handling and transferring member 1520, and the material shifting claw is arranged at the working end of the feeding and shifting claw member. The material handling claw 1510 and the material shifting claw can be arranged according to the specific structure of the middle plate, bottom shell and top cover of the product, and adopt the existing clamping claw or suction cup structure, which will not be described in detail here.

[0062] The finished product receiving device 1400 of this embodiment also includes the tray mechanism 1610 and the material transfer mechanism 1620 . The difference is that the material feeding and transferring claw component of the finished product receiving device 1400 is configured to drive the material transfer claw to transfer the material in the assembly fixture 411 to the tray mechanism 1610 .
