Fiber preforming production line and fiber preforming method

Abstract

The invention relates to a fiber preforming production line and a fiber preforming method. The fiber preforming production line comprises a conveying device for conveying fiber cloth, an automatic feeding mechanism, a heating device and a preforming press, and the automatic feeding mechanism, the heating device and the preforming press are sequentially arranged at the front end, the middle and therear end of the conveying device in the conveying direction of the fiber cloth to be formed. The conveying device comprises a rail assembly and a clamping device sliding along the rail assembly. Theclamping device comprises a front gripper conveying device arranged between the automatic feeding mechanism and the heating device, and a rear gripper conveying device arranged between the heating device and the preforming press. The front gripper conveying device conveys the fiber cloth to the heating device to be heated from the automatic feeding mechanism. The rear gripper conveying device conveys the heated fiber cloth to the preforming press to be prepressed and formed from the heating device. The front gripper conveying device and the rear gripper conveying device are gantry gripper mechanisms controlled by a servo electrical system.

Description

technical field [0001] The invention belongs to the field of fiber preforming equipment, and in particular relates to a fiber preforming production line and a fiber preforming method. Background technique [0002] Fiber preforming technology is a novel and practical fiber preform preparation technology developed since the early 1990s. The principle is to apply a small amount of special tackifying material-tackifier / setting agent on the surface of the reinforcing fiber or fabric, and make the laminated fabric or fiber bundle bonded by means of solvent volatilization, first heating up to soften or melt (pre-cured) and then cooling. The fiber preforms of the required shape, size and fiber volume content are prepared by means of pressure and shape molds. [0003] The Chinese patent with the publication number CN 109454795A discloses an automated production line for composite material preforming and its production process, specifically disclosing an automated production line con...

AI Technical Summary

Problems solved by technology

In the prior art, with regard to the material preforming automatic production line, the front-end feeding is generally carried out by a robot, and the pin-type gripper is used to place the material from the cloth table to the heating table for heating. After the heating is completed, the mechanical gripper is driven by a synchronous belt. The heated material in the heating table is sent to the forming press for pre-pressing and forming. However, the existing pre-forming production line has the following technical problems: First, the speed of the robot picking and loading process at the front end is slow, and the use of pin-type clamps Hands are prone to the problem of material falling off during the process of placing the fabric; second, the existing fabric table cannot realize automatic production on the assembly line; third, the speed of the loading robot is slow and the productivity is low
