Automatic grabbing device for composite material prefabricated body and laminated piece

Abstract

The invention discloses an automatic grabbing device for a composite material prefabricated body and a laminated piece. The automatic grabbing device comprises a frame assembly and a grabbing assembly. An aluminum alloy floral tube sectional material or an aluminum alloy octagonal tube is adopted as the material of a main frame and three auxiliary cross beams, and the effects that assembling is convenient and fast, the structural weight is light, and the stroke is easy to adjust are achieved. A quick-change disc is arranged in the middle of the side wall, away from a longitudinal beam, of a main cross beam, so that grippers are quickly replaced, quickly connected with a robot and communicate with a circuit and compressed air; grabbing assemblies are arranged on the auxiliary cross beams, proper vertical clamping force is generated, and the breathable prefabricated body and the laminated piece are picked up; by arranging height sensors on the auxiliary cross beams, the grabbing assemblies are guided to stably and rapidly pick up one workpiece each time, the requirement for stacking and discharging at the material position on a production line is met, the labor cost is reduced, and the production efficiency is improved; and therefore, automatic grabbing can be achieved, the production takt is shortened, the operation stability is kept, the comprehensive cost is reduced, and the applicability is wide.

Description

technical field [0001] The present disclosure generally relates to the technical field of mechanical automation, and in particular, relates to an automatic grabbing device for a composite material preform and a laminate. Background technique [0002] The application of new materials is the main source of lightweight automobiles. Resin-based composite materials with carbon fiber / glass fiber as reinforcement are ideal lightweight materials with low density, high specific strength, high specific modulus, fatigue resistance, and corrosion resistance. , overall forming and design strength and many other characteristics, the comprehensive performance exceeds that of aluminum alloy and high-strength steel, and has flourished in the process of automobile lightweighting in recent years. One of the challenges facing the use of composite materials in the automotive field is how to speed up the production cycle to meet the high-volume delivery requirements of the automotive industry. ...

Problems solved by technology

The traditional adsorption or clamping method is widely used in the grabbing of automotive injection molded parts and sheet metal parts, but it is not suitable for prefabricated bodies. The grabbing efficiency is low and the success rate is low, which affects the continuity of production; it is even more impossible to complete a single stack of multiple layers. The grabbing operation of laminated parts; at the same time, inappropriate mechanical loads can easily cause fabric deformation, fiber orientation deviation, and reduce the mechanical properties of the final molded product; if the deformation is too large, it may even lead to local wrinkles or fibers in the preforming process. Fracture, resulting in scrap prefab
