Multilayer carbon cloth stitching device

Abstract

The invention discloses a multilayer carbon cloth stitching device which comprises an acupuncture mechanism for conducting pre-acupuncture and stitching and needling, a latching mechanism, a horizontal workbench for clamping carbon cloth and a control system. A main shaft of the acupuncture mechanism is driven by a stepper motor and drives two eccentric wheels to rotate, the eccentric wheels drive a connection rod, the connection rod is connected with needle rods, one of the needle rods is a pre-acupuncture needle rod, the other one is a needling needle rod, and the two needle rods conduct reciprocating movement under the drive of the stepper motor; a main camshaft of the latching mechanism is connected with the stepper motor, the main camshaft is provided with two cams, and the main camshaft drives a bearded needle on a subsidiary camshaft to conduct reciprocating swing and axial reciprocating movement and conducts synchronous rotation with the acupuncture mechanism; the workbench is composed of an X-direction moving platform and a Y-direction moving platform, and the stepper motor is arranged on the workbench so as to achieve movement of a cloth containing supporting plate. By means of the pre-acupuncture, friction generated when carbon yarn penetrates through the carbon cloth is reduced, damage to the carbon yarn is lowered, and stitching of the multilayer carbon cloth is achieved.

Description

technical field [0001] The invention relates to a multi-layer carbon cloth sewing device for forming a carbon fiber three-dimensional fabric. Background technique [0002] Three-dimensional fabric is the fiber reinforced structure with the best performance developed in the past 40 years, and it is mainly used in aviation, aerospace, automobile, medical and new technology fields. Multi-layer carbon cloth stitching technology is a forming technology of three-dimensional fabrics. The process uses pre-cut square carbon cloth multi-layer stacked and flattened, and then placed on the carbon cloth placement platform of the horizontal workbench holding the carbon cloth for pre-stitching. The acupuncture mechanism for suturing and planting needles drives the two needle bars to reciprocate, and the locking mechanism performs locking after the yarn-drawing needle passes through the carbon cloth. The movement of the horizontal table holding the carbon cloth can precisely control the si...

Problems solved by technology

But its disadvantages are: only a single steel needle can prepuncture multi-layer carbon cloth sequentially, and manual threading is required after the needle prepuncture, which increases the production cycle, increases the production cost, and reduces labor efficiency.
