[0023] The utility model discloses a part assembly structure schematic diagram shows that the utility model discloses a part assembly structure schematic diagram. Figure 1 、 2As shown, this utility model has a base plate 603 fixedly installed on the bottom surface of the laying head mold 601, and a column tube 604 installed on the bottom surface of the base plate 603. The column tube 604 communicates with the inner cavity of the laying head mold 601 through the vent hole in the middle of the base plate 603. Through holes C605 for vacuum pipelines to enter the inner cavity of the laying head mold 601 are provided on both sides of the base plate 603. A stepped shaft 606 is fixedly installed at the bottom end of the column tube 604, and a pressure bead plate 610 is installed on the upper shaft section 607 of the stepped shaft 606. The top and bottom surfaces of the middle part of the worktable 103 are also connected. The pressure ball bearing 610 is installed in the pressure ball bearing mounting base 611 and the bearing mounting base 612 respectively. The pressure ball bearing 610 is set in the pressure ball bearing mounting base 611. The stepped shaft 606 passes through the hole 613 in the middle of the worktable plate 103 and the bearing mounting base 612. The bearing B614 is installed on the lower shaft section 608 of the stepped shaft 606. The vacuum chuck 602 is model Dingling PA-10. The pressure ball bearing 610 is model F3-8M51110. The bearing B614 is model F6208-2Z.

[0024] As attached Figure 1 , 2 As shown, the uniformly laid sheet rotating assembly of this utility model includes a synchronous pulley A615, a synchronous pulley B616, a synchronous belt 617, and a stepper motor 618. Synchronous pulley A615 is mounted on the shaft end 609 of the stepped shaft 606. A side-opening motor mounting bracket 619 is fixedly mounted on one side of the bottom surface of the worktable 103.

[0025] As attached Figures 1-6As shown, the 18 small vacuum suction cups 602 can vacuum suck the large sheet 2, so that the shape of the first layer of large sheet 2 after being heated and softened can be tightly wrapped on the surface of the sheet head mold 601.

In order to evenly stagger the overlapping parts between the petals of the large sheet 2 and avoid overlapping, the PLC control uniform sheet laying rotating assembly is used, that is, the stepping motor 618 drives the sheet head mold to rotate through the synchronous belt 617 from the starting position (the starting position is positioned at 0°) to lay 15 large sheets in the following cycle: 0°, left 30°, left 60°, 0°, right 30°, right 60°, 0°, left 30°, left 60°, 0°, right 30°, right 60°, 0°, left 30°, left 60°, and the 15 large sheets are automatically returned to 0° (the starting position) after laying the sheet, and the next cycle is performed (each large sheet is divided into 6 petals, and the overlapping amount between each sheet petal accounts for 1 / 3 of each sheet petal, and three large sheets can be evenly laid to fill a layer). That is, each large sheet corresponds to a rotation angle, and then the above actions are repeated. If the next step is to lay a small sheet, the sheet head mold does not rotate, that is, the rotation angle corresponding to all small sheets is 0°, so that the number of layers and the thickness of each cross-section sheet of the helmet are the same.

[0026] Finally, it should be pointed out that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement or improvement made within the spirit and principles of the present application should be included in the protection scope of the present application.
