However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various forms, which are provided only to complete the disclosure of the present invention and make those skilled in the art sufficiently understand the scope of the present invention, and the present invention is limited only by the scope of the claims. Like reference numerals denote like constituent elements throughout the specification.

Hereinafter, the present invention is described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 4, an evaporation crucible cart according to an embodiment includes a frame 1, a movable frame 2, and a lifting mechanism 3, wherein the movable frame 2 and the lifting mechanism 3 are both disposed on the frame 1, the movable frame 2 includes two loading platforms 21 disposed at different heights, the loading platforms 21 are used for placing a crucible 100, and the lifting mechanism 3 is connected to the movable frame 2 and can drive the movable frame 2 to move up and down.

Under the effect of elevating system 3, movable frame 2 can realize rising and descend, and when using evaporation coating crucible platform truck transportation crucible 100, movable frame 2 is in lower position so that the centre of gravity height is lower, guarantees the security of transportation. When the crucible 100 needs to be taken out from the evaporation crucible trolley, the movable frame body 2 rises, so that the crucible 100 at the lowest position on the movable frame body 2 is higher than the ground, the crucible 100 can be conveniently taken out from the evaporation crucible trolley safely and stably by personnel, and the crucible 100 is effectively prevented from being inclined at a larger angle in the process. Each side surface of the movable frame 2 is opened to allow the crucible 100 to enter and exit, and in actual operation, it is preferable to enter and exit the crucible 100 by using a side surface without the lifting mechanism 3 to prevent the crucible 100 from colliding with the lifting mechanism 3.

The number of the loading platforms 21 included in the movable frame 2 is not limited to two, and the movable frame 2 may include three or more loading platforms 21, and the number of the loading platforms 21 is selected according to actual needs.

Further, the lifting mechanism 3 comprises a motor 31, a lead screw 32 and a moving block 33, the motor 31 is fixed on the frame 1, the lead screw 32 is connected with the motor 31 and is vertically arranged, the moving block 33 is movably arranged on the lead screw 32, and the moving block 33 is fixed on the movable frame 2. The moving block 33 is configured like a ball nut, and when the motor 31 drives the screw shaft 32 to rotate, the moving block 33 can move up and down along the screw shaft 32, and the moving block 33 is fixed on the moving frame 2, so that the moving frame 2 also moves up and down. The lifting mechanism 3 with the structure can ensure the stable movement of the movable frame body 2, the crucible 100 arranged on the movable frame body 2 is not easy to shake in the lifting process, and the safety is high.

Of course, the elevating mechanism 3 is not limited to the form of this embodiment, and any structure that can smoothly drive the movable frame 2 to be elevated may be applied to the evaporation crucible cart.

Further, the evaporation crucible trolley of the embodiment further comprises guide posts 4, the guide posts 4 are fixed on the frame 1 and penetrate through the loading platform 21, and the guide posts 4 are vertically arranged. The guide post 4 can be spacing to the removal of activity framework 2, makes it can only move in vertical direction to improve the stability of activity framework 2 at the lift in-process, also guarantee that lead screw 32 does not receive the influence of radial shear force, avoid lead screw 32 bending deformation and can't use.

As shown in fig. 2, the movable frame 2 further includes connecting columns 22, the connecting columns 22 are vertically disposed, and the connecting columns 22 are connected to the respective loading platforms 21 and located at the edges of the loading platforms 21. The loading platforms 21 are all arranged in parallel, and the connecting columns 22 connect the loading platforms 21 into a whole, so as to form the movable frame body 2. In order to avoid the connecting column 22 occupying space on the loading platform 21 and hindering the placement and removal of the crucible 100, the connecting column 22 is provided at the edge of the loading platform 21. Of course, the number of the connecting columns 22 is not limited to one, and when the loading platform 21 is rectangular, a minimum of four connecting columns 22 are required to be respectively connected with four corners of the loading platform 21.

Further, the side surfaces of the connecting column 22 are in contact with the frame 1 and can slide with each other. The side of the connecting column 22 contacts with the frame 1, and the two can slide relatively, so that the frame 1 can also provide a limiting effect for the lifting of the movable frame 2, and the stability of the lifting process of the movable frame 2 is further improved.

In the present embodiment, the evaporation crucible cart includes two lifting mechanisms 3, and the two lifting mechanisms 3 are provided on opposite sides of the frame 1. Since the drawing shows only one side of the evaporation crucible cart, only one elevating mechanism 3 can be seen. Since the crucible 100 and the movable frame 2 have a large weight and a large volume, if only one lifting mechanism 3 is used to drive the movable frame 2, the stable lifting of the movable frame 2 can be ensured only by passing the lead screw 32 through the center of gravity of the movable frame 2, but this will occupy the space on the loading platform 21 for placing the crucible 100, which not only causes low operation efficiency, but also causes the lead screw 32 itself to be easily damaged by the impact of the crucible 100. By arranging the two lifting mechanisms 3 and arranging the two lifting mechanisms 3 on the two opposite sides of the frame 1, the space on the loading platform 21 can be not occupied, and the stable lifting of the movable frame body 2 is ensured.

Further, the lead screw 32 is arranged in the middle of the side face of the frame 1, so that the weight loaded on two sides of the lead screw 32 is the same, the acting force applied by the movable frame body 2 to the lead screw 32 is vertically downward, the moment causing the lead screw 32 to bend cannot be generated, and the lead screw 32 is prevented from being damaged.

As shown in fig. 3 and 4, the evaporation crucible cart of the present embodiment further includes a cushion pad 5, and the cushion pad 5 is provided at the bottom of the movable frame 2. The bottom of the movable frame 2 contacts the frame 1, and the cushion pad 5 can absorb the impact when the bottom of the movable frame 2 contacts the frame 1, so that the lifting mechanism 3 and the crucible 100 loaded on the movable frame 2 are well protected.

As shown in fig. 5, in another embodiment, the evaporation crucible cart includes four lifting mechanisms 3, two lifting mechanisms 3 are disposed at intervals on one side of the frame 1, and the other two lifting mechanisms 3 are disposed at intervals on the other side of the frame 1 opposite to each other. In the present embodiment, the screw rods 32 of the four lifting mechanisms 3 can also serve as a guide, so that the guide column 4 of the previous embodiment is not provided in the present embodiment. Since four elevating mechanisms 3 act on the movable frame 2 at the same time, the evaporation crucible cart of the present embodiment has a stronger load capacity.

Further, two lead screws 32 located on the same side of the frame 1 are respectively disposed near two ends of the frame 1. The two screw rods 32 on the same side of the frame 1 are far away from each other, so that the movable frame 2 can be stably supported, and the stability of the movable frame 2 in the lifting process is ensured.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, but may be manufactured in various forms, and those skilled in the art will appreciate that the present invention may be embodied in other specific forms without changing the technical spirit or essential features of the utility model.
