Abstract

The invention discloses a thermoplastic composite material automatic placement device and a method thereof. The thermoplastic composite material automatic placement device comprises a placement device, and the placement device is mounted on a support plate, a laser welding head of a laser welding device is fixed on one side of the placement device, and an ultrasonic vibration device is fixed on the other side of the placement device; a thermoplastic prepreg tape wound on a reel by the placement device is conveyed to a pressure roller through a guiding wheel and main and auxiliary driving rollers, the pressure of the pressure roller is controlled, the thermoplastic prepreg tape is fully contacted with a substrate; the laser beam from the laser welding head obliquely irradiates at the junction of the thermoplastic prepreg tape and the substrate, and an infrared temperature probe detects the processing temperature and feeds back to a computer to control the processing temperature in realtime; an ultrasonic vibration device applies ultrasonic shock to the thermoplastic prepreg tape behind the pressure roller. The laser of the device is used as a heat source, and the heating area is precise, and the heating speed is fast; the ultrasonic energy is introduced to improve the interface connection strength; and the temperature closed-loop control is used to improve the quality of the processed part.

Description

Technical field [0001] The invention belongs to the technical field of laser processing, and relates to an automatic placement device and method for thermoplastic composite materials. Background technique [0002] Structural parts made of high-performance composite fiber materials have the characteristics of high reinforcement, light weight and corrosion resistance, and are increasingly used in the fields of aerospace, automobiles, electrical appliances, and construction. Among them, the thermoplastic resin-based composite material has a short curing time, greatly shortens the molding cycle, has the characteristics of strong impact resistance and good welding performance, and has received more and more attention and research. However, due to the high melting point and high viscosity of the resin base material, high temperature and high pressure required for component molding, and stricter requirements on molding equipment, it restricts its further promotion and use, and automatic...
