Laser hot pressing lay-up forming device for thermoplastic composite material sheet

Abstract

The invention discloses a thermoplastic composite material plate laser hot-press laying and forming device, which comprises a host computer (101), a power supply module (102), a control unit (103), a hydraulic unit (104), and a temperature acquisition unit (105) , a laser heating unit (106), a laying platform (107) and a curing degree measuring unit (108). The device adopts the combination of laser-assisted heating and pressure roller roll forming process, adopts hydraulic roller rolling composite material prepreg tape forming to improve the uniformity of sheet forming, and accurately controls the laser power to ensure the quality and production efficiency of sheet forming. The online non-contact measurement of the degree of consolidation of composite materials is realized by using the Raman spectroscopy test method, and the multi-layer laying and laying of multiple motion tracks of composite material prepreg tapes are realized by automatic laying and molding, and no operator is required in the whole process on duty.

Description

technical field [0001] The invention relates to a laser hot-press laying and forming device for a thermoplastic composite material plate, which belongs to the technical field of laser manufacturing equipment. Background technique [0002] In the molding and manufacturing of thermoplastic composite materials, the traditional wet process manufacturing method uses glue-coated fibers to lay and consolidate the molding. Due to the poor uniformity of the glue in the composite material prepreg, the thickness of the glue is different, and the glue is wrapped. The viscosity of the applied glue is low, and the overflowing glue during the laying process needs to be removed by additional special personnel, resulting in poor laying uniformity and difficult cleaning of the production environment; after the laying is completed, the semi-finished product needs to be placed in a special Baking at a constant temperature in a high-temperature curing furnace for more than 24 hours consumes a lo...

The viscosity of the applied glue is low, and the overflowing glue during the laying process needs to be removed by additional special personnel, resulting in poor laying uniformity and difficult cleaning of the production environment; after the laying is completed, the semi-finished product needs to be placed in a special Baking at a constant temperature in a high-temperature curing furnace for more than 24 hours consumes a lot of energy, and the production efficiency is low. The composite product after consolidation has a high glue content, which is not conducive to lightweight

Auxiliary heating molding methods such as hot air guns, flames, and infrared rays, due to a series of problems such as uneven heating temperature field and small temperature difference between layers, lead to poor quality of formed components
