Description

Needle grip device {NEEDLE GRIP DEVICE}

The present invention relates to a needle grip device, and more particularly, to a needle grip device that can improve the grip performance of a transport object by applying a needle pin.

As disclosed in the Republic of Korea Patent Publication No. 2018-0071860, in recent years, as a body material according to the trend of high strength and light weight of the body, non-ferrous metal plate materials, such as ultra-high-strength steel, aluminum or magnesium, as well as carbon fiber reinforced plastic ( CFRP: CARBON FIBER REINFORCED PLASTICS) has been frequently used in plastic composite materials.

Here, since the plastic composite material has excellent strength, elastic modulus, light weight, and stability, it has been spotlighted as one of the major materials in the aviation field or the automobile field, and the future use of the plastic composite material is further expanded in the industry, and the production volume is also dramatically reduced It is expected to increase.

The plastic composite material is cured by impregnating a plastic resin with a fiber material, and can be produced by, for example, preparing carbon fibers in a winding shape or a fabric shape, and then impregnating and curing the carbon fibers in a plastic resin.

That is, plastic resins have excellent hardness, but are easily broken due to weak tensile strength, and carbon fibers have high tensile strength but no bending repulsion, so the plastic composite material can be produced by combining these plastic resins with carbon fibers.

The plastic composite material can be manufactured through a preform molding process and a Resin Transfer Molding (RTM) process. In the preform molding process, the prepreg impregnated with the resin in the fiber material is preheated and softened, and then laminated in a number of sheets, and the prepreg is pressed into a molding mold to form a preform molded body. Then, in the resin transfer molding process, a plurality of preform molded bodies are seated in a molding mold, and resin is injected into the molding mold to cure and a composite molded body having a desired shape is molded.

Here, the prepregage means an intermediate base material for a fiber-reinforced composite material, and refers to a molding material in which a fiber material (reinforced fiber) is pre-impregnated with a thermosetting resin or a matrix resin of a thermoplastic resin.

In the molding process of such a composite material, the object to be transferred, such as a prepreg and a preform molded body, impregnated with a resin, impregnated with a fiber material as a composite material fabric, is transferred to a subsequent process. I use a grip to say.

However, in the prior art, since the object to be molded forms a gap in the woven state, it is difficult to vacuum adsorb the object to be molded through the grip, and in the case of the prepreg, only the material on the top surface is adsorbed under vacuum suction pressure. There is a possibility that the other material is peeled off from the top material.

The items described in the background section are written to improve the understanding of the background of the invention, and may include matters other than the prior art already known to those skilled in the art.

The present invention is to provide a needle grip device capable of improving the grip performance of a transport object by applying a needle pin as invented in order to meet the above-mentioned needs of the prior art.

Needle grip device according to a first embodiment of the present invention, the grip body of a rectangular box shape with both sides open; A fixed shaft having both ends coupled to both side walls of the grip body; A pivoting shaft installed parallel to the fixed shaft and having both ends pivotally coupled to both side walls; A needle grip coupled to the middle of the rotation shaft; As a member coupled to the upper wall of the grip body, it is characterized in that it consists of an air cylinder unit that rotates the needle grip while pressing or releasing the upper surface of the needle grip.

The needle grip is a member for attaching a plurality of needle pins to the lower part and rotating the center of the rotation shaft by the operation of the air cylinder unit, thereby gripping the object to be transported through the bottom hole of the grip body with a needle pin. A pair of fitting parts fitted to the rotation shaft; A needle attachment member installed on the other side to cover the upper surface and the other side of the needle grip and attach the plurality of needle pins; The needle grip is centered around the pivot axis when the pressing operation of the air cylinder unit is released while the one end is located on the lower surface of the fixed shaft and the other end is located under the needle grip, being fitted to the outer periphery of the pivot shaft between the pair of fitting portions. It characterized in that it is made of a spring for return to rise to.

The needle pin is attached to the other side of the needle grip by a needle attachment member; Needle depth adjustment bolts are installed on the upper surface of the needle attachment member to adjust the lower protruding length of the needle pins at each upper side of the plurality of needle pins; A needle fixing bolt for fixing the plurality of needle pins is installed on the outer surface of the needle attachment member.

A magnet is installed between the plurality of bottom holes of the grip body to prevent leakage of the needle pin to the bottom of the bottom hole when the needle pin is broken.

According to the needle grip device of the present invention, as the piercing object is gripped with a rotary needle pin, it has an effect of improving the grip performance of the conveying object compared to the prior art using a vacuum suction force.
