Automatic material distributing equipment and process of one-way prepreg tape

Abstract

The invention provides an automatic material distributing equipment and process of one-way prepreg tape. The automatic material distributing equipment of the one-way prepreg tape comprises a feeding device, the feeding device comprises a regularizing platform, a feeding mechanism, a discharging mechanism, a detecting mechanism and a controller, the feeding mechanism and the discharging mechanism are separately arranged on the upper part of the regularizing platform, the regularizing platform comprises a conveying mechanism and a positioning mechanism, the positioning mechanism is arranged at the tail end of the conveying mechanism, the detecting mechanism is arranged on the next station of the positioning mechanism, and the feeding mechanism, the conveying mechanism, the positioning mechanism, the discharging mechanism and the detecting mechanism are in electric connection or signal connection with the controller separately. The position of the trailing edge of a previous piece of Y material is detected as a reference for the connection and laying of the latter piece of Y material, the detecting system is simplified, and the system operates more reliably; the impact of the operating accuracy of the system on the accuracy of the Y material placing position is reduced, and the influence of the cumulative error of the detected size or the actual size error of the Y material on theplacing accuracy is eliminated.

Description

Technical field [0001] The invention relates to the technical field of material composites, in particular to an automatic cloth equipment and a process for making unidirectional prepreg strips made of continuous fiber reinforced thermoplastic materials. Background technique [0002] Combine glass fiber, carbon fiber, aramid fiber or other fibers made of organic or inorganic materials (such as bamboo fiber, flax fiber, etc.), and a thermoplastic resin (such as PP, PE, PA6, PET, PEEK, PPS, etc.) ) The unidirectional reinforced composite material is called unidirectional continuous fiber reinforced thermoplastic composite tape, or unidirectional prepreg tape for short. This kind of unidirectional prepreg strip is the basic material unit for the production and manufacture of thermoplastic composite panels or sandwich composite panels using it as a skin layer. The composite panels made from it or various sandwich composite panels using it as a reinforced skin have quality Lightweight...

Problems solved by technology

Manual operation not only requires high labor costs, but also can easily cause boredom of the operator due to long-term repetitive actions, which in turn affects product quality; the use of process equipment is to allow the raw material to stop periodically. Complete the distributing process of material Y when material X is in the stop conveying state

The operating system is complex, and in addition to the necessary length measuring system, clamping mechanism, etc., the following devices are required to realize automatic material distribution operation: On the one hand, the X material unwinding device for rolls needs to have a driving mechanism, and the driving mechanism needs to be in accordance with The material distribution cycle is started and stopped, but the commonly used coil unwinding equipment is not equipped with a similar drive mechanism; on the other hand, in order to avoid the material alignment error caused by the Y material when it is moving, an online welding method is required when completing the Y material distribution. Methods, such as ultrasonic and other thermoplastic welding devices to physically connect Y material and X material
