A multifunctional fiber laying head

Abstract

A multifunctional fiber placement head comprises guide roller mechanisms, a retransmission mechanism, a heating mechanism, upper lining paper recycling mechanisms, a shearing mechanism, pressing roller mechanisms and lower lining paper recycling mechanisms. The guide roller mechanisms are used for enabling a fiber strip to penetrate through the placement head, and the fiber strip in the placement head reaches the retransmission mechanism through the guide roller mechanisms, passes through the heating mechanism and then is compacted and placed on a mandrel under the mutual effect of the upper lining paper recycling mechanisms, the lower lining paper recycling mechanisms and the pressing roller mechanisms. The shearing mechanism is arranged at the positions close to pressing roller heads of the pressing roller mechanisms. The guide roller mechanisms are composed of simple plane four-bar mechanisms, each pressing roller head is independently controlled by a motor, the stretching length and width of pressing rollers can be changed in real time according to different placement mandrel grooves, and stress concentration is avoided. The infrared heating principle is adopted for the heating mechanism, and swing of the pressing roller heads is skillfully limited. The retransmission mechanism is further simplified, and a retransmission air cylinder directly pushes an air cylinder connection rod to drive a connection frame to complete a retransmission task.

Description

Technical field [0001] The invention relates to the field of fiber laying equipment, in particular to a multifunctional fiber laying head. Background technique [0002] Because composite materials have high strength, high precision, high reliability and other performance advantages, it replaces many traditional materials, such as aerospace, weapons, nuclear industry, civilian product manufacturing and other fields have a wide range of applications. In this regard, composite material molding technology is particularly important. At present, the main process methods of composite material molding include manual layup method, fiber winding method, fiber placement method, autoclave curing method, composite material liquid molding method, etc. [0003] As early as the 1970s, fiber placement technology has appeared in western developed countries, and foreign countries have realized the trajectory planning and placement of some common industrial components. This technology has become a co...
