The photographing unit (not shown) is a device capable of capturing an image, for example, a camera. The photographing unit is installed on an upper part of the fixing jig 1 to generate a photographed image photographing a display panel mounted on the fixing jig 1 on the upper part. can do.

To this end, the photographing unit (not shown) is preferably coupled to the fixing jig 1 through a member such as a driving arm whose rotation angle and height are adjusted, but is installed as long as it can be formed at an angle for photographing the display panel. There is no restriction on the structure.

A control module (not shown) is a member installed inside the fixing jig 1 to perform control and calculation. The control module (not shown) is installed for each of the flow pipes 31 based on a captured image received from a photographing unit (not shown). Opening and closing of the plurality of open / close valves 35 can be selectively controlled.

Specifically, the control module (not shown) analyzes the photographed image to estimate a region in which foreign matter is formed in the entire region of the display panel, and controls the opening / closing valve installed at an air inlet located near the estimated region in which the foreign matter is formed. In addition, the opening and closing valve installed in the air inlet located near the remaining region except the estimated region may be controlled to be closed.

For example, as shown in FIG. 17, when it is determined that a foreign matter is formed on the upper right side of the display panel by analyzing a photographed image, the control module (not shown) is preset based on the center point of the region A in which the foreign matter is formed. It is possible to extract the air inlet 35 arranged within the reference distance B, for example 10 cm.

The control module (not shown) operates the air injector 32 while controlling the opening / closing valve 35 installed at the air inlet 50 located in the vicinity of the region where the estimated foreign matter is formed (region A). By spraying the air can be controlled to be injected only to the region where the foreign matter is formed.

On the other hand, the control module (not shown) in response to the foreign matter attached to the display panel in the process of attaching the touch panel by periodically updating the opening / closing valves in real time by periodically updating the region where the foreign matter is formed at predetermined time intervals. By controlling the air injection angle and area in real time, it is possible to minimize foreign substances formed on the display panel.

On the other hand, each of the components constituting the fixing jig 1 according to the present invention may be applied with the adhesive composition according to the present invention and bonded with other components.

For example, the adhesive composition according to an embodiment of the present invention, the elastic member 27 and the unit clamping unit 25, the elastic member 27 and the groove 10, the flow path tube 31 and the fixing jig ( 1) an adhesive composition formed between 1 to 5 parts by weight of thermoplastic resin, 5 to 40 parts by weight of tackifying resin, 1 to 5 parts by weight of rosin, 1 to 10 parts by weight of plasticizer, and 1 to 1 part of thermoplastic resin. 10 parts by weight and 0.1 to 1 part by weight of antioxidant. The present invention is a hot melt adhesive composition, in detail look at each component below.

The thermoplastic resin serves as a main component of the composition to control adhesion and cohesion. If it contains a vinyl group or a hydroxyl group, the kind is not particularly limited, and for example, ethylene vinyl acetate copolymer, polyvinylacetate, polyvinyl alcohol, ethylene-acrylic acid copolymer and ethylene-methacrylic acid copolymer, polyurethane It may be composed of any one or more selected from the group consisting of.

The content of the thermoplastic resin is preferably 40 to 80 parts by weight based on the total composition. If the content is less than 40 parts by weight, the melt viscosity is high and the melt flow index is low, the workability is very poor, if the content is more than 80 parts by weight it is difficult to exert sufficient adhesive force to be applied directly to the fabric.

The tackifier resin is a low molecular weight resin, lowers the melt viscosity to improve workability, improves the initial wettability of adhesion and adhesion of the adhesive on the surface of the adherend, and enables control of the solidification time.

The tackifying resin is not particularly limited in kind, but is preferably a petroleum resin. More specifically, the tackifier resin may be composed of one or more selected from the group consisting of aliphatic hydrocarbon resins, alicyclic hydrocarbon resins, aromatic hydrocarbon resins, aromatic hydrocarbon-modified aliphatic hydrocarbon resins, and hydrogenated hydrocarbon resins.

The aliphatic hydrocarbon resins are commercial products such as Hikorez A-1100, Hikorez A-1100S, Hikorez C-1100, Hikorez R-1100, Hikorez R-1100S, and the like. In addition, alicyclic hydrocarbon resins include hydrocarbon resins containing dicyclopentadiene (DCPD) as monomers, and aromatic hydrocarbon resins are commercially available from Kolon Oil Co., Ltd. of Hikotack P-110S, Hikotack P-120, Hikotack P-120HS, Hikotack P-120S, Hikotack P-140, Hikotack P-140M, Hikotack P-150, Hikotack P-160, Hikotack P-90, Hikotack P-90S, Hirenol PL-1000, Hirenol PL-400. In addition, aromatic hydrocarbon-modified aliphatic hydrocarbon resins include Hikorez T-1080, Hikorez T-1100, etc. of Kolon Oils. Hydrogenated hydrocarbon resins may also be subdivided into hydrogenated aliphatic hydrocarbon resins, hydrogenated aromatic hydrocarbon resins, and the like, and commercially available from Kolon Oil Co., Ltd. Sukorez SU-120, Sukorez SU-130 and Sukorez SU-90.

The tackifier resin is preferably a hydrocarbon resin having 4 to 10 carbon atoms in the monomer, and specifically, a C5 aliphatic resin, a C9 aromatic resin, a C5 / C9 aliphatic / aromatic copolymer resin, or the like may be used.

In addition, the tackifying resin of the present invention is more preferably characterized in that the hydrocarbon hydrocarbon resin containing dicyclopentadiene as a monomer, commercially available from Sukorez D-300, Sukorez D-390, Kolon Emulsifier (Korea), Sukorez SU-100, Sukorez SU-110, Sukorez SU-120, SukorezSU-130 and Sukorez SU-90.

On the other hand, the adhesive composition of the present invention is preferably used by mixing the biodegradable hypoallergenic resin together with the various petroleum resins described above.

The biodegradable hypoallergenic resin may be prepared by melt-mixing a monomer of a polymer into a biodegradable polymer, and polylactic acid is preferably used as the biodegradable polymer.

The polylactic acid is a polyester synthesized by polycondensation of lactate or ring-opening polymerization of lactide, and has a medium physical property between polyamide and polyethylene terephthalate, and is mainly made of natural vegetable sugar components obtained from potatoes and corn. Biodegradability is high, but generally has high hardness, low elasticity, and poor durability.

The biodegradable polymer is melt-mixed with the same polymer monomer, wherein the biodegradable polymer is partially bonded with the monomer to cause chain breakage, thereby lowering the overall number average molecular weight. As the number average molecular weight falls, the physical properties that can be used as an adhesive are exhibited, and the workability is increased.

With respect to 100 parts by weight of the polylactic acid, the lactic acid monomer may be mixed 20 to 30 parts by weight. When the monomer is mixed in less than 20 parts by weight, the number average molecular weight is high and hard to be used as a pressure-sensitive adhesive, when the monomer exceeds 40 parts by weight may be difficult to use as a pressure-sensitive adhesive also occurs.

It is preferable that the mixing ratio of the petroleum resin and the biodegradable hypoallergenic resin is 1 to 2: 1 (w / w), and when the mixing ratio of the petroleum resin is too high, the biodegradable hypoallergenic effect is hard to come out, If the mixing ratio is too high, economic efficiency may be lowered and the overall adhesive effect may be lowered.

In addition, the content of the tackifying resin is preferably 5 to 40 parts by weight relative to the total composition. If the content is less than 5 parts by weight, the effect of lowering the melt viscosity due to the addition of the tackifying resin is insufficient, and there is a fear that the increase in the melt flow index is not so large that the workability may not be satisfactorily reached, and the content is more than 30 parts by weight. If the melt flow index increase rate due to the excess of the tackifier resin is not large, the economical efficiency is lowered, and the content of the thermoplastic polymer is relatively reduced, thereby reducing the overall physical properties of the composition.

The rosin acts to improve the overall adhesion of the adhesive composition and is harmless to the human body and acts as a natural preservative. The content of the rosin is preferably 1 to 5 parts by weight based on the total composition. If the content is less than 1 part by weight, it is difficult to obtain an adhesive improvement effect, and if the content is more than 5 parts by weight, the adhesive force increases during processing, making it difficult to process the product.

The plasticizer is used to impart flexibility and adhesion to the polymer, and the type of plasticizer according to the present invention is not particularly limited, and for example, sorbitol, ethylene glycol, glycerin, glycerin diacetate, and pentaerythritol It may consist of one or more selected from the group consisting of.

The amount of the plasticizer is preferably 1 to 10 parts by weight based on the total composition. If the content is less than 1 part by weight, the effect of the addition of the plasticizer is insignificant. If the content is more than 10 parts by weight, the economical efficiency may be reduced by excessive use of the plasticizer, and there is a concern that the overall physical properties of the adhesive may be lowered.

The filler is used to control the reinforcement and flow of the composition. The type of filler is not particularly limited, and for example, calcium carbonate, clay, bentonite, calcium stearate or the like can be used.

On the other hand, the adhesive composition of this invention is easy to generate | occur | produce odor and bacteria on the application environment. Accordingly, in order to reduce the odor and bacteria generation while controlling the reinforcement and flow of the adhesive composition, it is preferable to use a mixture of stone powder and pulp powder as a filler. Stone powder can achieve high strength without using additives due to the compactness of the particles, and the cracking of the adhesive hardly occurs even when the temperature change is large due to low volumetric strain according to the surrounding environment.

The stone powder may be used in the form of powder of various rocks such as loess, marble, elvan, granite, gemstone, and is characterized in that the loess having various functions such as antibacterial, antifungal, and ultraviolet radiation is used.

The pulp powder serves to agglomerate the stone powders while sucking the liquid components, to improve the miscibility and improve the cohesion between the components. At this time, the stone powder and the pulp powder is preferably mixed in a ratio of about 7: 3 to 8: 2 (w / w).

The content of the filler is preferably 1 to 10 parts by weight based on the total composition. If the content is less than 1 part by weight, the effect of adding the filler is insignificant, and if the content is more than 10 parts by weight, there is a concern that the overall physical properties of the adhesive may be lowered.

The antioxidant is intended to improve the change in viscosity, yellowing, deterioration of adhesion and degradation of durability due to oxidation and decomposition, and the type thereof is not particularly limited and specifically, phenols, aromatic amines, citric acid, or ascorbic acid may be used. Can be.

The content of the antioxidant is preferably 0.1 to 1 parts by weight relative to the total composition. If the content is less than 0.1 parts by weight, the effect of the addition of the antioxidant is inadequate, and if the content is more than 1 part by weight, not only the economy of the adhesive is lowered but also the overall physical properties may be lowered.

On the other hand, the adhesive composition of the present invention is subjected to a press operation on the substrate, at this time there is a possibility that a poor adhesion due to the amount of the composition is removed due to the presence of holes in the substrate.

Thus, the adhesive composition of the present invention may further include a nano silica that can improve the adhesion by allowing the adhesive composition to be uniformly distributed on the substrate surface. At this time, the content of the nano silica is preferably 0.1 to 5 parts by weight, and the size of the nano silica (primary particles) is preferably 100 nm or less.

If the content of the nano-silica is less than 0.1 parts by weight, the effect of the addition of nano-silica is insignificant, and if the content exceeds 5 parts by weight, not only the adhesive strength is lowered, but also a bad phenomenon that blooming (blooming) occurs on the surface of the adhesive over time May occur.

Hereinafter, the configuration of the present invention and its effects through specific examples and comparative examples will be described in more detail. However, this embodiment is intended to illustrate the present invention in more detail, and the scope of the present invention is not limited to these examples.
