[0029] The lifting assembly 4 includes a fixing frame 41, a threaded rod 42, a motor 43, a slide 44, a square plate 45, and a short shaft 46. The top side of the fixing frame 41 is fixedly connected to the bottom side of the electric push rod 33, one end of the threaded rod 42 is rotatably connected to the bottom side of the fixing frame 41, a threaded hole is provided on the middle surface of the first connecting frame 32, the threaded rod 42 passes through the threaded hole and is threadedly connected to the first connecting frame 32, the rotating shaft of the motor 43 is fixedly connected to the other end of the threaded rod 42, the inner surface of the slide 44 is slidably connected to the outer side of the motor 43, the top side of the square plate 45 is fixedly connected to the bottom side of the slide 44, and the first connecting frame 32 and the square plate 45 are fixedly connected via a short shaft 46.

[0030] Specifically, a contactor and a brake are disposed inside the motor 43 . The contactor can change the direction of the motor 43 , and the brake can lock the rotating shaft of the motor 43 when the motor 43 is powered off.

The electric push rod 33 slides in the slide groove of the first connecting frame 32 through the slider, and the positioning mechanism 35 slides upward along the second long groove on the surface of the placement table 2. Then the power supply of the motor 43 is turned off. At this time, the bottom side of the positioning mechanism 35 is just flush with the lower surface of the first long groove inside the placement table 2. Then the power supply of the electric push rod 33 is started, and the electric push rod 33 begins to extend. The electric push rod 33 drives the second connecting frame 34 to move toward the middle of the placement table 2, and the second connecting frame 34 pushes the positioning block 351 to move. As the positioning block 351 moves, the buffer pad 354 will first contact the side of the carton. At this time, the buffer pad 354 squeezes the spring 353. When the sensor 352 contacts the side of the carton, the sensor 352 sends a signal to the controller inside the electric push rod 33. The controller controls the electric push rod 33 to stop working, and then the base 1 lifts the carton to the conveyor belt, and then controls the electric push rod 33 and the motor 43 to reset the position of the positioning block 351, and finally moves the carton to the surface of the conveyor belt to complete the loading process.
