The driving motor 4034 is connected to the screw rod and is used for driving the screw rod to rotate, so that the moving seat 4033 moves along the axial direction of the screw rod. The power panel 70 has a motor driving module 701 for driving the driving motor 4034 to work. When the driving motor 4034 is started, the driving motor 4034 drives the screw rod to rotate, and the rotational motion of the screw rod is transferred to the movable seat 4033 through the threaded fit, so that the movable seat 4033 can be driven to move along the axial direction of the screw rod. Movement of the movable base 4033 drives the tray 402 to push in or out.

In this embodiment, the driving device 403 having the above-described structure can control the switching of the tray 402 between the push-in position and the out position. The rotary motion of the driving motor 4034 enables the tray 402 to precisely move along the axial direction of the screw rod through the synergistic effect of the screw rod and the moving seat 4033, so that the structure is high in stability and flexible in operation, and the pushing and moving actions can be effectively realized.

That is, when the tray 402 moves to the pushed-in position, the blocking piece 4036 also moves, and moves to the sensing area of the photoelectric switch 4035. This means that the position of the flap 4036 will trigger the opto-electronic switch 4035. When the opto-electronic switch 4035 is triggered, it generates a signal that is transmitted to the main control circuit board 60. The main control circuit board 60 controls the driving motor 4034 to stop operating, thereby stopping the movement of the movable base 4033. This mechanism ensures a stable stop of the tray 402 in the pushed-in position, preventing over-pushing.

The combination of the photoelectric switch 4035 and the blocking piece 4036 in the embodiment realizes automatic stop control of the driving motor 4034, improves the safety and stability of the system, and ensures accurate stop of the tray 402 at the correct position, thereby improving the position precision and further ensuring the detection precision.
