In this embodiment, four receiving mechanisms 2 are provided, that is, two receiving mechanisms 2 are respectively provided at the two sides of the object 100 to be carried, so that the receiving mechanisms 2 can carry the object 100 more stably. As shown in FIGS. 5 to 7 , each of the receiving mechanisms 2 includes a power source 21 and a receiving member 22. The power source 21 may be a cylinder, etc. The power source 21 is fixed at an appropriate position, for example, it may be locked on a frame 23 or various supporting structures. The receiving member 22 is connected to the power source 21, and the power source 21 can push the receiving member 22 to move toward or away from the object 100 to be carried. In this embodiment, the receiving member 22 is an L-shaped seat, and the receiving member 22 may have a horizontal plate 221 and a vertical plate 222. The horizontal plate 221 is horizontal. Preferably, the horizontal plate 221 has a receiving surface 2211, the receiving surface 2211 faces upward, the receiving surface 2211 is horizontal, and the receiving surface 2211 can be used to receive the object 100 to be carried.

When the power source 21 pushes the receiving member 22 to move toward the object 100 to a position, the horizontal plate 221 of the receiving member 22 can receive the object 100.

The lifting mechanism 1 can drive the carried object 100 to a predetermined height so that a pick-and-place device (such as a robot arm) can pick up and place the carried object 100. That is, the lifting seat 13 of the lifting mechanism 1 can drive the carried objects 100 to rise to a predetermined height one by one so that the carried objects 100 can be taken out at the predetermined height. When the number of objects 100 to be loaded reaches a predetermined number, the power source 21 can push the receiving member 22 to move toward the objects 100, so that the receiving member 22 can be used to temporarily store the objects 100, so that the objects 100 can be positioned at a predetermined height, so that the loading and unloading device can continuously load and unload the objects 100.

When the objects 100 are stacked to a predetermined amount, the power source 21 can push the receiving member 22 to move toward the objects 100 so that the receiving member 22 can receive the objects 100 continuously transported by the pick-up and placement device (such as a robot arm), so that the objects 100 can be positioned at a predetermined height so that the pick-up and placement device can continuously pick up and place the objects 100. At this time, the lifting mechanism 1 can be lowered to the discharge area to deliver the objects 100 on the lifting mechanism 1, and then the lifting mechanism 1 will rise immediately to receive the objects 100 temporarily stored on the receiving members 22, so that it can produce continuously. In this embodiment, since the production can be carried out uninterruptedly, for example, five stacks of loads can be moved every hour, which can save about 2 minutes, and about 48 minutes can be saved in a day. Therefore, continuous production can effectively increase the utilization rate of the machine.

In addition, the present invention may further include a positioning plate 3, at least one first driving device 4, a plurality of positioning members 5 and a plurality of second driving devices 6.

The second driving devices 6 can be cylinders, etc. The second driving devices 6 are fixed at appropriate positions, the second driving devices 6 are fixed at a predetermined height, the positioning members 5 are respectively connected to the second driving devices 6, and the positioning members 5 are located at the same horizontal height. The positioning plate 3 corresponds to one side of the object 100, and the positioning members 5 correspond to the other three sides of the object 100. When the object 100 rises, the positioning plate 3 can move (retreat) to a position away from the object 100 to prevent the object 100 from contacting the positioning plate 3, so as to reduce dust generation. When the object 100 is lifted to a predetermined position, the positioning plate 3 moves (advances) to a position in contact with the object 100, so that one side of the object 100 on the uppermost layer can be positioned by the positioning plate 3, and the second driving devices 6 can push the positioning members 5 respectively, so that the other three sides of the object 100 on the uppermost layer can be positioned by the positioning members 5 respectively, so that the four sides of the object 100 can be positioned to achieve a center positioning effect, so that the object 100 can be accurately taken and placed.
