The driving mechanism 400 is disposed on the first support base 100, the driving mechanism 400 may be disposed on an outer side of the first support base 100, and the first support base 100 is away from one side of the link mechanism 300, so as to prevent the influence on the rotation of the link mechanism 300, further, the driving mechanism 400 may also be disposed on the second support base 200, and the embodiment of the present invention does not limit the position where the driving mechanism 400 is disposed. The driving mechanism 400 is in driving connection with the link mechanism 300 to realize the driving of the link mechanism 300.

In a specific working process, the workpiece 600 is firstly assembled on the movable device 500, and the workpiece 600 may be a 3DP sculpture, and the 3DP sculpture is turned over in this way to glue and harden all parts of the 3DP sculpture. The movable device 500 drives the workpiece 600 to move so that the workpiece 600 can approach the turnover device, and then the workpiece 600 can be assembled on the link mechanism 300 by a manual or automatic device, and further, the driving mechanism 400 drives the link mechanism 300 to rotate so as to turn over the workpiece 600, thereby further operating the workpiece 600. Of course, in this process, in order to facilitate the assembly of the workpiece 600 on the turnover device, the workpiece 600 may be provided with a through hole matching with the link mechanism 300 during the forming process, and, in order to prevent the damage of the workpiece 600, the through hole may pass through the center of the workpiece 600 and be located at a simple thick position of the workpiece 600. At the time of assembly, the link mechanism 300 is assembled in the through hole to facilitate the integral assembly.

As can be seen from the above, in the workpiece turnover system disclosed in the embodiment of the present invention, the movable device 500 drives the workpiece 600 to move, and the turnover device drives the workpiece 600 to turn over, so as to further operate the workpiece 600. Compared with the existing manual turning mode, the workpiece turning system disclosed by the embodiment of the invention is simple in structure and convenient to operate, and can turn over workpieces 600 with complex structures, such as large 3DP sculpture blocks and some 3DP sculpture blocks with complex structures, so that the problems that the workpieces 600 with complex structures are difficult to turn over and the structures are easy to damage in the existing process are solved, the workpieces 600 are prevented from being scrapped, and the corresponding potential safety hazards are solved.
