[0003] Currently, when using a robotic arm for 3D printing, a layer of plastic film or plastic plate is usually laid on the workbench to facilitate workers to take the printed parts. However, the plastic film and plastic plate laid on the workbench are easy to slide, causing the printed parts to fall over. When printing objects with higher heights, it is inconvenient for workers to take them because of the high height of some workbenches. Utility Model Content

[0008] As a further solution of the utility model: a threaded section is provided on the sliding rod, a pressure plate is connected above the sliding rod, a rubber pad is connected below the pressure plate, and the sliding rod is threadedly connected to the second threaded sleeve through the threaded section.

[0009] As a further solution of the utility model: the guide groove is of spiral design, the sliding rod is connected with a guide block, and the guide block slides in the guide groove.

[0010] As a further solution of the utility model: a handle is connected to the top of the placing table, a notch groove is opened on the placing table, and two ends of the threaded rod are rotatably mounted below the workbench and above the bottom plate respectively.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The multi-robotic arm 3D printing device is provided with a motor, a worm, a worm wheel, a threaded rod, a smooth rod, a moving block, a first threaded sleeve and a lifting platform. The motor drives the worm to rotate, so that the worm can drive the threaded rod to rotate by meshing with the worm wheel. As the threaded rod rotates, the moving block can drive the lifting platform to move up and down along the threaded rod through the first threaded sleeve, thereby reducing the overall height of the lifting platform, making it convenient for staff to take prints at a higher height. When the lifting platform descends, the auxiliary block will move along the smooth rod, thereby assisting and limiting the movement of the lifting platform through the smooth rod, thereby improving the stability of the movement of the lifting platform.

[0014] 2. The multi-robotic arm 3D printing device installs the placement table in the installation groove by arranging a support plate, a first spring, a hollow column, a guide groove, a sliding rod, a guide block, a threaded section and a second threaded sleeve, so that the placement table can press down the support plate and the first spring, and then rotate the sliding rod to make the guide block slide in the guide groove. The guide sliding rod through the guide groove will drive the pressure plate to rotate 180°, so that one end of the pressure plate connected to the rubber pad can press down the placement table, so that the placement table presses the first spring to prevent the first spring from rebounding, and the threaded section on the sliding rod will also enter the second threaded sleeve, thereby fixing the sliding rod to prevent the sliding rod from sliding, so that the pressure plate can press and fix the placement table in the installation groove to prevent the placement table from sliding and causing the printed part to tip over.

[0023] A guide groove 20 is provided on the hollow column 16, and the guide groove 20 is of spiral design. A guide block 27 is connected to the sliding rod 23, and the guide block 27 slides in the guide groove 20.
