The moving distance of the pilot gas butt flange B 3232 is compensated by the inflation hose 3236. One end of the inflation hose 3236 is communicated with the pilot gas butt flange B 3232, and the other end is connected with the inflation pipe 3237. The other end of the inflation pipe 3237 is connected with the on-off valve 32310, and the other end of the on-off valve 32310 is sealed and communicated with the inflation manifold 32313 through the inflation branch pipe 32311.

When the pneumatic pilot vacuum valve 32318 needs to be closed, the on-off valve 32310 is closed first, the air supply is stopped, and then the gas release valve 3244 is opened, so that the compressed air in the pilot gas pipe 32319 is discharged. Since there is no positive pressure in the pilot gas pipe 32319, the pneumatic pilot vacuum valve 32318 is closed at this time, and then the pilot gas butt driving device 3235 drives the pilot gas butt flange B 3232 to separate from the pilot gas butt flange A 32317.

[0046] As shown in Figure 5 and Figure 7 Since the silica gel plate is elastic, a concave surface is formed after the upper silica gel plate 5101 and the lower silica gel plate 5201 are installed due to gravity, the curvature of the concave surface is adjusted, and the curvature is close to the curvature of the component to be pressed. The curvature of the upper and lower silica gel plates is adjusted, the component is placed between the two silica gel plates, the two silica gel plates are almost coincident with the component after the cover is closed, and the excess gas in the flexible pressing box is extracted when vacuumizing. Since the silica gel plate has a certain elasticity, the part of the component that is not coincident with the silica gel plate is stretched by the elasticity of the silica gel plate, and the part is supplemented, so that the space between the two silica gel plates is extracted into a vacuum state, and the component is pressed into a whole by the atmospheric pressure outside. The upper silica gel plate and the lower silica gel plate are adjusted to be consistent with the curvature of the component to be pressed in advance, so that the two silica gel plates are almost coincident with the component.

[0047] Preferably, the flexible press box moving device is arranged to move the flexible press box along a certain path. The flexible press box moving device comprises track wheels 5012 and a moving thrust rod 5011. A plurality of track wheels 5012 are fixed on the lower box base 501 and are arranged on both sides of the flexible press box. The moving thrust rod 5011 is fixed below the lower box base 501 between the track wheels arranged on both sides. The moving thrust rod is used to receive external force when the flexible press box is automatically operated. When the flexible press box is automatically operated, the moving thrust rod is pushed forward by external force, so that the track wheels carry the flexible press box to move forward, thereby moving the entire flexible press box. Preferably, the moving thrust rod is rigid.

[0048] The flexible press box is provided with a flexible press box moving device. The flexible press box can be moved along a track under the drive of the flexible press box moving device, can carry the transfer laminated assembly into different stations to complete the entire laminating process, and is convenient for complete implementation of the entire laminating process. With the above structure provided with the flexible press box moving device, the flexible press box not only can provide a sealed cavity during laminating, but also can complete laminating of the laminated assembly under vacuum state, and can be used as a device for carrying and transferring the laminated assembly, thereby solving the technical problem of unstable transmission of the curved rigid assembly when the curved rigid assembly is transmitted by the conveying belt, and achieving one box with multiple uses. When the moving thrust rod is pushed by external force, the flexible press box can run along the track under the drive of the flexible press box moving device. The track can support the flexible press box and guide the forward direction of the flexible press box. The flexible press box has the following advantages: under normal circumstances, in order to achieve good sealing and non-deformation under pressure at high temperature, the box body of the flexible press box is made of metal components and has a relatively large weight, one flexible press box can reach several hundred kilograms, the stress of the conveying device is relatively concentrated, the flexible press box with the structure of the present application can run along the track under the drive of external force, the track supports the flexible press box by gravity, and the external force only needs to overcome the friction between the track and the track wheels. Therefore, relatively small force can be applied to realize transmission of the laminated assembly, and the transmission device will not be deformed due to the weight of the flexible press box. More importantly, the technical problem of unstable transmission of the curved rigid assembly by the existing high-temperature cloth conveying belt can be solved, and normal transmission can be realized. The flexible press box is not only a laminating device, but also a device for carrying and transporting the curved rigid assembly.

[0049] The utility model discloses a method for laminating rigid curved surface laminated assembly as follows: placing the curved surface laminated assembly into a vacuum sealing cavity formed by upper and lower silica gel plates, locating between the upper and lower silica gel plates, vacuumizing the vacuum sealing cavity, making it reach a predetermined vacuum degree and making the upper and lower silica gel plates tightly adhere to the laminated assembly, using the pressure difference between the inside and outside of the upper and lower silica gel plates to press the laminated assembly, reaching a predetermined pressure. When vacuumizing, the vacuum cavity can be heated to reach a curing temperature. Using the above method, since the upper and lower silica gel plates are flexible, they will follow the shape of the assembly under the effect of elasticity when acting on the laminated assembly, thus any curved surface shape including a flat surface assembly can be pressed, and the surface shape of the assembly is well matched, thus the versatility is good, and there is no requirement for the matching between the shape of the pressure head of the mold and the curved surface of the assembly, reducing the processing difficulty.
