AI Technical Summary

Technical Problem

In the existing multi-layer pressing process of carbon fiber cloth, the vacuum membrane and heat insulation cotton are prone to displacement when they come into contact with the inner wall of the vacuum bag, requiring manual adjustment and resulting in low production efficiency.

Method used

A multi-layer carbon fiber cloth air bubble removal system was designed, including a base, a top cover and bottom auxiliary components. The system achieves automatic positioning and sealing of the mold, vacuum membrane and insulation cotton through piston, pull rope and positioning components. Combined with negative pressure drive mechanical linkage, it realizes air bubble removal, mold sealing and self-adaptive locking.

Benefits of technology

It improves processing efficiency, ensures molding quality, reduces energy consumption, enhances interlayer shear strength and production efficiency, and reduces scrap rate.

Abstract

The present application relates to carbon fiber cloth processing technical field, especially for a kind of carbon fiber cloth multilayer pressing bubble removal system and its use method, including the air extraction interface and sealing pad for external air extraction pump, air extraction interface fixedly connected in base one side, detachable upper cover is installed on the upper end of base;Base includes hard seat, channel hole is opened in the middle of hard seat, adaptive slot is opened in the middle position of channel hole, square groove and middle groove are opened in the inside of the upper end of hard seat, limit slot is opened in the both sides of both ends of hard seat, adaptive hole and the side hole being communicated with channel hole are opened in the inside of limit slot;Upper cover includes hard cover plate, plastic film one is fixedly connected in the inside of hard cover plate.This application can achieve the same effect as vacuum bag, in the actual use process, the mold, vacuum film and thermal insulation cotton can be directly put into the inside from the upper end, without putting from one side, after putting, mold, vacuum film and thermal insulation cotton do not need to be arranged again, thereby the processing efficiency of this process is improved.
