Conveying device

1 . A conveying device, comprising:

a mounting seat and a moving assembly, wherein the mounting seat is configured to move under drive of the moving assembly along a first direction, and the moving assembly comprises a base;

a bearing platform having an axis and a rotating assembly, wherein the bearing platform is rotatably provided on the mounting seat via the rotating assembly and is configured to rotate about the axis of the bearing platform under drive of the rotating assembly along a second direction, wherein the axis is perpendicular to the first direction, and the second direction is perpendicular to the first direction;

a driving assembly; and

a transmission assembly in transmission connection to the driving assembly, the moving assembly, and the rotating assembly respectively, configured to transmit driving force of the driving assembly to the moving assembly, such that the moving assembly is configured to drive the mounting seat and the bearing platform to move, and transmit the driving force of the driving assembly to the rotating assembly for the rotating assembly driving the bearing platform to rotate,

wherein the transmission assembly comprises a second rotating element and a third rotating element which are rotatably provided on the mounting seat,

wherein the rotating assembly comprises a first rotating element which is rotatably provided on the mounting seat and connected to the bearing platform to drive the bearing platform to rotate relative to the mounting seat, a first gear is coaxially provided on the first rotating element, a second gear is coaxially provided on the second rotating element, and the first gear and the second gear are meshed with each other,

wherein a third gear is coaxially provided on the second rotating element, the third rotating element is in a gear transmission with the second rotating element, a rack extending in the first direction is fixedly provided on the base, and the third rotating element is in a rack and gear transmission with the base, and

wherein the transmission assembly is adapted to synchronously transmit the driving force of the driving assembly to the moving assembly and the rotating assembly, respectively, via the third rotating element and the second rotating element, so that the bearing platform is configured to be moved and rotated synchronously.

2 . The conveying device of claim 1 ,

wherein the transmission assembly is in transmission connection to the first rotating element, to transmit the driving force of the driving assembly to the first rotating element and thus to drive the first rotating element to rotate.

3 . The conveying device of claim 2 ,

wherein the driving assembly is connected to the second rotating element to drive the second rotating element to rotate.

4 . The conveying device of claim 2 , wherein the second rotating element and the first rotating element have axes parallel to each other, and have at least two transmission engagement points which are provided to be spaced apart along an axial direction of the second rotating element.

5 . The conveying device of claim 1 , wherein the moving assembly comprises:

a movable element which is slidably fitted to the base and is connected to the mounting seat so as to drive the mounting seat to move relative to the base;

wherein the transmission assembly is provided on the mounting seat and is in a transmission connection to the base, to transmit the driving force of the driving assembly to the base and thus to drive the movable element to move.

6 . The conveying device of claim 5 ,

wherein the driving assembly is connected to the second rotating element to drive the second rotating element to rotate.

7 . The conveying device of claim 1 , wherein

the driving assembly comprises: a motor provided on the mounting seat, and an output shaft of the motor is in a gear transmission with the second rotating element.

8 . The conveying device of claim 1 , wherein the mounting seat comprises a baseplate and two side plates, and the two side plates are provided to be spaced apart on the baseplate, and

wherein the bearing platform is located in a space between the two side plates, and two sides of the bearing platform are rotatably connected to the two side plates of the mounting seat through the rotating assembly.

9 . The conveying device of claim 1 , wherein the bearing platform is provided with a bearing surface, and configured such that when the bearing platform is being moved toward a side, the bearing platform is rotated until the bearing surface faces the side.
