Description

Technical Field

[0001] This utility model relates to the field of composite material processing equipment technology, and in particular to a multi-axis automatic yarn laying and weaving device for fiber fabrics. Background Technology

[0002] Fiber-reinforced composite materials have been applied in aerospace, rail transportation, and high-end wind turbine blade manufacturing due to their excellent properties of being lightweight and high-strength. Automatic fiber placement technology is a key process for realizing the automated and high-precision manufacturing of composite material components. Its core equipment is the automatic fiber placement device. Existing automatic fiber placement devices adopt a gantry or robot structure, and the fiber placement head at the end moves on the mold surface through multi-axis linkage control to complete the fiber placement and compaction.

[0003] In actual production, different specifications or types of compaction rollers need to be replaced for fiber fabrics of different widths and materials or for different curvature areas of molds. The existing equipment uses bolts to fix the roller mechanism, which is complicated to disassemble and assemble, requires manual operation with tools, and consumes a lot of time, significantly reducing production efficiency and equipment utilization. It is difficult to adapt to the production needs of multi-tasking, small batch, and rapid changeover. In addition, for components with complex three-dimensional curved surfaces, the fiber placement device needs to precisely control the posture of the compaction roller to keep it perpendicular to the placement surface to ensure the quality of the layer. However, the existing equipment has limited freedom of movement, and its adjustment mechanism is difficult to flexibly and accurately adjust the angle of the compaction roller. When dealing with surfaces with large curvature changes, defects such as loose bonding, air bubbles, or wrinkles may occur, affecting the mechanical properties and precision of the final product.

[0004] Therefore, this utility model proposes a multi-axis automatic yarn laying and weaving device for fiber fabrics to overcome the shortcomings of the prior art. Utility Model Content

A rack and pinion conveyor belt 41 is fixedly connected to the top of the two support bases 1 respectively. A transmission component 42 is engaged with the top of the two rack and pinion conveyor belts 41 respectively. The top of the two transmission components 42 is fixedly connected to the bottom of the same support frame 43. The rack and pinion conveyor belts 41 drive the transmission components 42 to move, which allows the machine to move horizontally and longitudinally. A slot is opened inside the support frame 43.

During operation, first align the top of the housing 2 with the inside of the fixed base 35, then push the extrusion rod 31 downward with the telescopic rod 33. The movement of the extrusion rod 31 causes the ball 32 to move outward of the groove 34. At this time, the outer surface of the ball 32 engages with the groove 36, allowing the machine to quickly change different types of pressure roller mechanisms 3. After engagement, by adjusting the multi-directional control in the mechanism 4, the machine can better fit the curved surface to improve the operation accuracy.
