Description

Adhesion Chuck , Adhesion Pad micro lens pattern design of Big or middle size Transfer device for Glass , plate etc.}

The present invention relates to a design of an adhesive chuck and an adhesive pad for glass and medium and large plate transfer devices, and more specifically, prevention of contamination and strong vertical adhesive force through a new design of an adhesive chuck formed on a base plate that can move vertically and horizontally In case of over-desorption, it can be detached with a remarkably weak force, and it is a 3D micro-pattern design with a size of several micro to several tens of micro for the adhesive chuck and adhesive pad designed to minimize contamination by adhesion traces on the adherend.

Displays such as OLED and LCD are manufactured through a complicated process through the transfer of medium and large-area glass and medium and large plates. Accordingly, it is designed to control the medium and large glass and medium and large plates with a strong adhesive force when transporting for easy transport and accurate positioning, and a remarkably weak force when detaching, so that it can adhere to the adherend with minimal traces. It must be moved at a precise and fast speed and put down in the correct position.

Therefore, in recent years, displays such as OLEDs and LCDs are a transport technology that seeks to minimize contamination of the adhesive surface along with the precision and reliability of peeling at the correct position when transporting medium and large-area glass and medium and large plates. research is emerging as an issue.

Conventionally, in order to transport medium and large-area glass and medium and large plates, the electrostatic chuck is a method of adsorption and desorption by electrostatic force, and the medium and large plates for transport are adhered by an adhesive layer and additional devices such as diaphragms are independent. It is common to use an adhesive chuck that is used and detached.

On the other hand, in the case of the electrostatic chuck method, an even electrostatic force acts on the entire contact surface of medium and large-area glass and medium and large plates to fix it, so flatness is guaranteed, and the electrostatic force can be adjusted, so the adsorption force can be controlled. .

In addition, in the case of the adhesive chuck method, unlike the electrostatic chuck method, there is no need for an additional device, and since the adsorption force is generated by the simple contact of the adhesive layer, the structure is simple and has excellent advantages in terms of cost.

However, in the case of the electrostatic chuck method, the circuit for generating electrostatic force is complicated and expensive, and there is a problem in that medium and large area glass and medium and large plates are contaminated and damaged by static electricity.

In addition, in the case of the adhesive chuck method, it is difficult to maintain a constant adhesive force due to contamination of the adhesive layer and atmospheric pressure, depending on the position of medium and large-area glass and medium and large plates, which causes problems such as position errors.

The present invention has been devised to solve the above problems, and an object of the present invention is to adhere medium and large area glass and medium and large plates according to time and pressure or pollution degree without a separate complicated and independent configuration. It is to provide a transfer plate for medium and large area glass and medium and large plate transfer device having a structure to minimize the change in adhesive force.

In addition, another object of the present invention is to apply a 3D structure in the shape of a fine pattern having a micro height of several micro to several tens of micro and a size of several micro to several tens of micro to the adhesive chuck and the adhesive pad. To develop an adhesive chuck and pad that minimizes changes in adherends such as glass and plate due to contamination and adhesion traces on the adherend from the adhesive surface.

On the other hand, the objects of the present invention are not limited to the above-mentioned objects, and other objects not mentioned will be clearly understood by those skilled in the art from the following description.

In order to achieve the above object, the present invention provides a base plate that can move up, down, left, and right, and a 3D micropattern of tens to hundreds of micro-patterns formed on one surface of the base plate to apply a 3D micropattern of an adhesive chuck and an adhesive pad, The lowering of the adhesive force and the adhesive force with the adherend to be adhered are adjusted to the distance and number of the fine pattern of the 3D structure, so that a certain adhesive force is applied. It provides a transfer plate for medium and large-area glass and medium and large plate transfer devices, characterized in that the adhesion surface with the adherend is minimized.

In a preferred embodiment, the pressure-sensitive adhesive cell is a composite prepared by mixing an elastic body and an adhesive.

In a preferred embodiment, in the adhesive cell, the micro-pattern 3D adhesive pattern surface protruding from the base plate is adhered to the adherend whose adhesive strength is adjusted.

The present invention has the following excellent effects.

According to the transfer plate for medium and large area glass and medium and large plate transfer device of the present invention, the medium and large area glass and medium and large plate can be uniformly processed by the micro-adhesive chuck structure formed on the base plate without a separate complicated configuration. It has excellent adhesive properties by force, and it can prevent contamination by the environment and adherends and minimize adhesion traces on glass and medium and large plates.

In addition, according to the transfer plate for medium and large-area glass and medium and large plate transfer apparatus of the present invention, the adhesive surface is made of a structure of numerous micro 3D patterns, so it is relatively easy to control the adhesive force, and The effect of contamination can be minimized due to the effect of several tens of micro heights, and the adhesion traces of the adherend glass and medium and large plates are minimized by the effect of the fine pattern on the adhesive surface, thereby minimizing the need for subsequent cleaning processes, etc. It has the advantage of saving money and time
