[0033] like Figure 1-12As shown, a device for layering multi-layer products comprises a frame 1 and a product handling mechanism, wherein the frame 1 is within the travel range of the product handling mechanism, a product placement rotating table 2 is provided in the center of the frame 1, a workpiece suction device is provided on the product placement rotating table 2, a spacer layer handling module is provided on the frame 1 outside the product placement rotating table 2, the travel range of the spacer layer handling module is greater than the upper surface of the product placement rotating table 2, at least part of the upper surface of the product placement rotating table 2 is within the travel range of the spacer layer handling module, and the frame 1 is provided with a first lifting device 3 and a second lifting device 4 outside the product placement rotating table 2 to contact the product The spacing layer end uncovering module and the breaking module are matched with the product placement rotating table 2. The frame 1 is also provided with a layering module matched with the product placement rotating table 2. The spacing layer end uncovering module is located above the layering module. The height of the breaking module is lower than the height of the layering module. The distance from the connection between the layering module and the frame 1 to the product placement rotating table 2 is greater than the distance from the connection between the breaking module and the frame 1 to the product placement rotating table 2. The distance from the connection between the spacing layer end uncovering module and the frame 1 to the product placement rotating table 2 is greater than the distance from the connection between the layering module and the frame 1 to the product placement rotating table 2.

[0034] In the present application, when in use, the product transport mechanism transports the product to be layered to the product placement rotating table 2, and then the end of the spacing layer is opened by the module to grind the end of the spacing layer on the layered product, so that the end of the spacing layer is ground off a little, so that the functional layer on the layered product is exposed, so that there is a layer difference between the spacing layer and the functional layer on the layered product. During the grinding process, the product placement rotating table 2 can be rotated as needed, so that the surrounding of the spacing layer on the layered product can be ground off. Afterwards, the seam breaking module separates the spacing layer and the functional layer on the layered product, so that the layered product is automatically layered. Among them, since the seam breaking step is before the layering step, the distance from the connection between the layering module and the frame 1 to the product placement rotating table 2 is designed to be greater than the distance from the connection between the seam breaking module and the frame 1 to the product placement rotating table 2, so that the seam breaking module will not affect the layering of the layered product by the layering module after the seam breaking is completed.

[0035] As a preferred method, the frame 1 is provided with a product output roller frame 5 on one side of the product placement rotating table 2, and the conveying start end of the product output roller frame 5 is within the travel range of the product transport mechanism.

Of course, the roller frame for conveying products is a prior art and will not be described in detail here. Figure 3An alternative structure is shown in .

[0036] As a preferred method, since some products need to be turned over (i.e., the original upper surface becomes the lower surface) after the spacer layer is separated, the frame 1 is further provided with a turning module at the conveying start end of the product output roller frame 5. With this design, the turning module can be directly used on the frame 1 to turn over without manual operation.

The first suction cup 9 is arranged on the lower surface of the first mounting cross frame 8. When flipping the functional layer (after the layered product separates the spacing layer, only the functional layer remains, that is, the product processed in this application), the first suction cup 9 on the first mounting cross frame 8 adsorbs the functional layer, and then the third lifting device 10 rises to a certain height, the first rotating motor 6 rotates, thereby driving the first rotating rod 7 to rotate, and then driving the first mounting cross frame 8 and the functional layer to rotate 180 degrees, and then the third lifting device 10 descends, and the flipped functional layer is placed on the frame 1 (also on the product output roller frame 5), and the product output roller frame 5 outputs the functional layer to the outside of the frame 1.
