Description

Creel quick replacement device adopting gun replacement disc in automatic thread laying

Technical Field

The utility model relates to an automatic technical field of putting of fibre especially relates to an adopt creel quick replacement device who trades rifle dish in automatic spreading silk.

Background

The fiber reinforced resin matrix composite material has been widely used in the fields of aerospace, wind power generation blades, automobile manufacturing and the like due to the characteristics of high specific strength, high specific modulus, fatigue resistance and corrosion resistance. In the face of parts with complex structures and huge sizes, the requirements on production efficiency and quality cannot be met by manual laying. The automatic fiber laying equipment adopts an industrial robot as a moving part, can realize the manufacture of a large-curvature and complex special-shaped body component by matching with a creel and a fiber laying head, and has the advantages of high laying efficiency, high material utilization rate and high automation degree.

At present, the automatic fiber placement equipment is generally 8 tows or 16 tows, and can achieve placement of carbon fibers, glass fibers, dry fibers and thermoplastic composite materials. Before laying, operators often need to do a great deal of preparation work, including roll fixing and wire threading. The filament bundle can smoothly pass through a clamping, re-feeding and shearing mechanism in the filament laying head and reach the compression roller. When the material roll in the creel is used up, the machine needs to be stopped to replace the material roll, and the loading action is repeated, so that the whole process is complicated. Especially for a multi-tow laying device, a great deal of time waste is caused, and the working efficiency cannot be improved.

In addition, some composite components for special applications often need to be intermingled with different types of fibers. For example, in some applications, the long-term contact between the carbon fiber laminate and the metal can cause electrochemical corrosion on the contact surface, thereby affecting the mechanical properties of the part, so that in the final stage of preparing such carbon fiber laminate, it is often necessary to lay a layer of glass fiber on the surface layer to serve as an insulating layer. For the automatic laying equipment, the carbon fiber material roll needs to be replaced by the glass fiber material roll when the automatic laying equipment is laid at the last time, and then operations such as wire threading are carried out, so that additional time cost is increased.
