Cushion Roll Core for Adhesive High Efficiency

The present invention relates to a cushion roll core for high-efficiency adhesive, and more particularly, to a cushion roll core capable of high-efficiency adhesive for effectively adhering and separating and removing foreign matter adhered to a surface of an article having a curved or uneven surface. will be.

In general, a clean room is operated in a bio industry such as medicine, pharmaceutical or food, or an industrial manufacturing plant such as semiconductor, electronics, display, film, printing, optical or lens. The clean room is a room with a clean air environment by controlling indoor air environment to a lower level than the general work environment that controls the cleanliness and pollutants such as suspended dust and harmful gas bacteria.

In order to maintain the cleanliness of the clean room, it is necessary to design, operate and operate the following several conditions. That is, it should not have contaminants such as dust and microorganisms in the room. The interior materials of the room are made of materials that do not have a rash, the air supply in the room is filtered by a hepa filter, and the occupants are changed into dustproof clothes and entered through an air shower, and the incoming materials are made as small as possible and pass box (pass) It is necessary to minimize the contaminants entering the room by paying attention to dust prevention such as through a box. Moreover, the rash in the room should be minimized, and the rash by the worker entering the room or by the work itself cannot be avoided, but it is necessary to make the rash as small as possible. In addition, by quickly removing contaminants in the room, rashes and other contaminants generated in the room need to be removed to the outside quickly due to a structure that does not remain in the clean room and adequate ventilation. Laminar flow type clean rooms are extremely harmful for removing suspended pollutants and require countermeasures such as local exhaust for harmful gases.

The clean room is classified into classes according to the cleanliness of the indoor air, so that the clean room is suitable for the purpose of use. Class classification is performed by the amount of dust suspended in indoor air, but the display method is represented by a dust standard of 0.5 µm or more in 1 ft ㅃ of air according to US Federal Standard 209B. For example, 100 refers to the cleanliness of 100 or less suspended dusts of 0.5 μm or more in 1 foot of air.

As such, despite maintaining cleanliness of indoor air in the clean room, the surface of the product may be contaminated with fine dust or stains due to static electricity or various conditions.

In the past, an adhesive roll was mainly used to remove contaminants such as fine dust or stains adsorbed or adhered to a product. The adhesive roll is a film in which an adhesive is adhered to a core.

However, if the conventional adhesive roll core has poor smoothness, the film layer wound around the core also has poor smoothness. In the case of using such an adhesive roll, it was not easy to remove stains or fine dust adsorbed or adhered to rough parts or uneven surfaces of the product with the adhesive roll.

Moreover, when the smoothness of the core was poor, there was a closed end in which the roll state of the film layer was deteriorated and the adhesive strength was also lowered, such as air bubbles between the core and the adhesive film.

Due to this problem, the clean room of the Utility Model Publication No. 2004-8677 filed by the applicant (inventor) of the present invention and a cushion adhesive roll for removing dust from LCD, PDP, PCB, and FPC are thermoformed embossed on the adhesive-coated laminated film. There was a cushion adhesive roll in which marks were formed.

However, in the prior art, when embossing was formed on the laminated film, it was possible to effectively remove fine dust or stains on a somewhat rough or smooth curved surface of the product, but on the deep curved surface and uneven surface, fine dust or stains could not be removed. There was a weak problem.

The present invention is to solve the above problems, it is adsorbed on the surface, curved surface or uneven surface of the product in an industrial manufacturing plant, such as semiconductor, electronic, display, film, printing, optical or lens that must maintain a certain degree of cleanliness The purpose is to remove stuck fine dust or stains more effectively with a cushioned roll core to improve the yield of the product.

In order to achieve the above object, the present invention provides a cushion member having a predetermined thickness with a cushion on the surface of a hard synthetic resin core into which a roller is inserted, and an adhesive film coated with an adhesive on an outer surface of the cushion member is highly efficient. It is characterized by providing a wear cushion roll core.

The present invention, by the above solution means, even if the smoothness of the first core can be corrected the smoothness of the film layer, reducing the adhesive film loss to the impact defects applied to the adhesive roll, and several times without loss of the adhesive film It is possible to repeatedly use the adhesive roll, to reduce the processing cost for the treatment of the discarded adhesive roll and the adhesive film, there is an effect that can be maintained for damage to the cushion member during the use of the adhesive roll.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the high efficiency adhesive cushion roll core of the present invention.

1 is a perspective view showing a high-efficiency pressure-sensitive adhesive cushion roll of the present invention, Figure 2 is a perspective view of the incision of the cushion roll, Figure 3 is an enlarged view of the main part of the cushion roll.

First, the high-efficiency adhesive cushion roll core of the present invention is for removing the fine dust or stain adsorbed or adhered between the surface of the product, the curved surface or the uneven surface with an adhesive roll composed of a cushion member.

The core 12 is formed of a cylindrical material made of hard synthetic resin. The core 12 is made of ABS (acrylonitrile butadiene styrene copolymer) resin, PS (polystyrene) resin, FRP (fiber glass reinforced plastic) resin, PE (polyethylene) resin and the like. The size of the core 12 is within 3 to 14 inches and the width is within 10 to 2,000 mm.

A roller 20 is inserted into the core 12 to rotate the core 12. Furthermore, in FIG. 5, a roller 20 consisting of roller assemblies 22 is inserted into the core 12 to rotate the core 12. The roller assembly 22 is also applied to the small or medium or larger to allow the operator to directly roll on the surface of the product to remove the foreign matter. Thus, the size of the core 12 will be determined by the small, medium or large rollers 22.

A cushion member 14 having a predetermined thickness with a cushion is adhered to and fixed to the surface of the core 12. The cushion member 14 is made of polyethylene foam or the like, and the thickness of the cushion member 14 is approximately 0.5 to 3 mm. The cushion member 14 serves to cushion the core 12.

The pressure-sensitive adhesive film 16 is wound on the outer side of the cushion member 14 by a predetermined number of times, and the pressure-sensitive adhesive 17 is coated on the outside of the pressure-sensitive adhesive film 16. The pressure-sensitive adhesive 17 can adhere to and remove foreign substances such as dirt or stain adsorbed or fixed on the surface of the product. Moreover, the adhesive 17 is applied to the adhesive surface of the outer surface of the adhesive film 16 so that the adhesive 17 of the outermost adhesive film 16 removes foreign substances, and the adhesive film 16 laminated on the inside thereof. The pressure-sensitive adhesive 17 of the adhesive surface serves to adhesively fix the pressure-sensitive adhesive film 16 wound on the outside.

Furthermore, the adhesive film 16 is formed to cut the outermost adhesive film 16 when the cutting line 18 is formed at regular intervals so that the adhesive force drops while a large amount of foreign matter adheres to the adhesive 17. Therefore, the perforation line 18 allows the adhesive film 16 to be formed according to the width or distance wound on the cushion member 14.

As such, the cushion member 14 allows the adhesive film 16 to more effectively adhere to fine dust or stain adsorbed or adhered to the surface, curved surface or uneven surface of the product.

In addition, FIG. 4A illustrates that when the adhesive roll R1 removes foreign substances such as dust or dirt on the surface of the substrate S, the adhesive roll R1 passes through the uneven surface to generate a gap G, thereby causing the substrate S to be removed. The foreign matter on the surface is not completely removed, but when the foreign matter such as dust or stain on the surface of the substrate S is removed by the adhesive roll R2 of the present invention of FIG. 4B, the adhesive roll R2 passes between the uneven surfaces. While the gap G is not generated, foreign substances on the surface of the substrate are completely removed. Therefore, the adhesive roll of the present invention can cleanly remove the foreign matter adsorbed or fixed to the surface of the curved surface or uneven surface of the product by cushioning the cushion member on the core.

Therefore, when the adhesive roll 10 is rotated while being in surface contact with the surface of the product to reduce or absorb the impact between the outermost surface of the adhesive film 16 and the product to effectively remove the foreign matter on the surface of the product. . This is to prevent the impact is applied to the inside of the adhesive roll 10 and at the same time to more effectively adhere to the fine dust or foreign matter between the curved surface or uneven surface that is not easily adhered to be removed.

Therefore, the adhesive film loss of about 10 to 25% due to the impact defect applied to the adhesive roll 10 could be reduced. And it was possible to use the adhesive roll repeatedly many times without losing the adhesive film. And it is possible to reduce the treatment cost by reducing the generation of carbon dioxide during incineration for the treatment of discarded adhesive roll and adhesive film. It is also possible to maintain against damage of the cushion member during use of the adhesive roll. That is, when the cushioning member fixed to the core is damaged, the damaged cushioning member is peeled off and the new cushioning member is adhered to the cushioning member.

In addition, the present invention will be expected to be the same effect as the present invention if the cushion member is fixed to the core surface of the adhesive roll currently in use.

In addition, the cushion member of the present invention can minimize the damage of the film from the external impact by wrapping the optical film, the diffusion film or the reflective film, as well as the adhesive film, even in a portion that can be bent or bent of a light and thin product Will be available.

While the invention has been shown and described in connection with specific embodiments thereof, it is well known in the art that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the claims. Anyone who has can easily find out.
