First, the film supply unit 10 is a device for continuously supplying a film material F formed by stacking a plurality of films. The structure of the film supply unit 10 is not particularly limited. For example, as shown in Fig. 4, the film supply unit 10 may have a roll structure capable of continuously feeding the film web F wound in a roll form.

The film material F supplied by the film supply unit 10 is supplied from the idle rollers R provided between the film supply unit 10 and the recovery unit 80, And is conveyed toward the collection unit 80 by the tension.

The kind of the film material F that can be supplied by the film supply unit 10 is not particularly limited. For example, the film fabric (F) is, is that each of the adhesive on both surfaces coated by the adhesive force of the adhesive layer (A ₁₎ a base film (A ₂₎ is formed (F _O), adhesive layer (A ₁₎ (A ₂₎ Base the release which enables separation attached to one surface of the film (F _O) film (F _R), the release film (F _R) is laminated on the outer face, the reinforcement film (F having a relatively low laser absorption rate than the release film (F _R) of may include _S), and the adhesive layer (a ₁₎ (protective film (F _P) is attached to a ₂₎ by adhesion other surface of the base film (F _O) base film (F _O) which is one side and the counter of the .

The base film (F _o ) is a film which becomes the backbone of the film fabric (F). The kind of the base film (F ₀ ) is not particularly limited. For example, the base film (F _O ) may be an optical film for a display panel. Adhesive layers A ₁ and A ₂ are formed on the both surfaces of the base film F ₀ , that is, on the upper and lower surfaces of the base film F ₀ , respectively. The kind of the adhesive is not particularly limited, and an adhesive generally used for adhering the film can be used for forming the adhesive layer (A ₁ ) (A ₂ ).

The release film F _R is a film that protects the adhesive layer A ₁ from the outside. The adhesive layer (A ₁₎ to use the base film (F _O), by a the panel member (P) if the previous adhesive layer (A ₁₎ for attachment to the exposure to the external adhesive layer (A ₁₎ dust and other contamination from the air material There is a possibility of contamination.

, To protect the adhesive layer (A ₁₎ The release film (F _R) adhesive layer (A ₁₎ to adhere to the adhesive layer (A ₁₎ with the material to be bonded detachably to contamination from the outside in order to solve this problem. The material of the release film (F _R ) is not particularly limited. For example, the release film (F _R ) may comprise at least one of polyethylene terephthalate (PET) and polyethylene (PE).

The release film (F _R), as illustrated in Figure 4, the base film (F _O) when adhered to the adhesive layer (A ₁₎ formed in the base film (F _O) if may be attached to enable separation on the have. However, the present invention is not limited thereto, and the release film F _R may be peelably attached to the upper surface of the base film F _o . Hereinafter, for convenience of explanation, the present invention will be described based on a case where the releasing film (F _R ) is peelably attached to the upper surface of the base film (F _O ).

The reinforcing film F _S is a member for preventing the film fabric F from being broken during the process of attaching the film. In the conventional film-attaching apparatus 100, the film material F is transferred using the tension acting on the release film F _R when the film-attaching process is carried out. Therefore, when the film material F is laser-cut, only the remaining films should be selectively cut so that the release film F _R is not cut off. However, due to various reasons, the release film F _R is partially cut, (F _R ) is broken. Then, the tension acting on the release film F _R is removed, and the feeding of the film end F is stopped, thereby stopping the film adhering process.

In order to solve this problem, the film material F is laminated on the outer surface of the release film F _R so that the tensile force acting on the film material F is not removed even if the release film F _R is broken during the process of attaching the film. And a reinforcement film (F _S ).

Reinforcing film (F _S) is, as shown in Figure 5, is laminated on the lower surface of the release film _(R F), is formed of a material having a relatively low laser absorption rate compared to the release film _(R F). That is, the reinforcing film F _S is formed of a material that is relatively difficult to cut by laser than the release film F _R. The material of the reinforcing film (F _S ) is not particularly limited. For example, the reinforcing film (F _S ) may comprise at least one of polycarbonate (PC), polyurethane (PU), and polytetrafluoroethylene (PTFE).

As the reinforcing film F _S is provided, even if the release film F _R is partially laser-cut and the release film F _R is broken, the reinforcing film F _S is not laser- (10) and a recovery unit (80) described later. Therefore, even if breakage occurs in the release film F _R , the film end F can be continuously conveyed by the tension acting on the reinforcement film F _S , and therefore, due to the breakage of the release film F _R , It is possible to effectively prevent the process from being stopped.

The protective film F _P is a film for protecting the base film F _o from the outside. When attached to the panel member (P) to one surface of the base film (F _O) the other surface of the base member which is opposite to the one surface of the base film (F _O) are exposed to the outside. The other surface of the base film (F _O) exposed to the outside are subject to damage in contact with the other member of the outside, providing a protective film (F _P) for protecting the base film (F _O) from the outside in order to solve this problem, . For example, a protective film (F _P) as shown in Figure 5 is adhered to the adhesive layer (A ₂₎ formed on the top surface of the base film (F _O) may be attached to the upper surface of the base film (F _O) . However, the present invention is not limited thereto, and the protective film F _P may be interposed between the base film F _o and the release film F _R.

The kind of the panel member P to which the panel supply unit 20 can supply is not particularly limited. For example, the panel member P may be a display panel having a structure corresponding to the base film (F _o ) formed of the optical film for a display panel.

Meanwhile, the panel supply unit 20 has been described as having a conveyor structure including a plurality of rollers 22, but is not limited thereto. That is, various devices capable of transferring the vacuum adsorbent and other panel members P capable of vacuum-sucking the panel member P can be employed as the panel supply unit 20. [ Hereinafter, the present invention will be described with reference to the case where the panel supply unit 20 has a conveyor structure including a plurality of rollers 22 for convenience of explanation.

Next, the meander measuring unit 30 is a device for measuring the meandering angle of the film fabric F. In general, roll devices can cause meandering in the fabric due to various non-uniformities in tension acting on the fabric during the transfer of the fabric. In the case of carrying out the film cutting process and the film attaching process while leaving such meandering as it is, the films attached to the base film (F ₀ ) and other panel members (P) do not have a predetermined size or are attached at predetermined positions There is a possibility that a failure may occur. Therefore, the film applying apparatus 1 according to the preferred embodiment of the present invention includes a meandering measurement unit 30 for measuring the meandering angle of the film fabric F.

The meander measurement unit 30 is installed on the downstream side of the film supply unit 10, as shown in Fig. More specifically, the meander measuring unit 30 is provided at a position corresponding to the edge of the film material F being fed and fed from the film feeding unit 10 to measure the meandering and meandering angle of the film material F can do.

Next, the smoothing unit 40 is a device for smoothing the film fabric F. In order to smoothly perform the laser cutting process on the film fabric F, it is preferable that the laser cutting process is performed on the film fabric F with the film fabric F smooth. Therefore, the film applying apparatus 1 according to the preferred embodiment of the present invention further includes a smoothing unit 40 for smoothing the film stock F.

The structure of the smoothing unit 40 is not particularly limited. For example, the smoothing unit 40 is installed on the downstream side of the meander measuring unit 30, as shown in Fig. And a pair of smoothing rollers 42 and 44 for pressing the upper and lower surfaces of the film fabric F to smooth the film fabric F, respectively. As the smoothing unit 40 is provided as described above, the film material F enters the laser unit 60 in a smoothed state, so that laser cutting processing on the film material F can be performed precisely.

 Next, the failure detection unit 50 is a device for detecting failure of the film material F. In general, when manufacturing a film fabric, a defective portion (B) where a defect has occurred is marked with a defective mark. 4, the defect detection unit 50 is provided on the downstream side of the smoothing unit 40 and detects the defect portion B of the film fabric F during the production of the film fabric F The defective mark and the defective portion (B) of the film material F can be specified by detecting the defective mark. The structure of the failure detection unit 50 is not particularly limited. For example, the defect detection unit 50 may be constituted by a vision system capable of analyzing an image of the film stock F to detect a defective mark, or may detect the magnetism of the defective mark when the defective mark is magnetic A magnetic sensor or the like.

The failure detection unit 50 applies a failure signal to the control unit to determine whether the film material F is defective and the position of the defective portion B and the control unit controls the driving of the laser unit 60 to detect the film material F ) Other than the defective portion (B) in which the defective mark is marked. Therefore, the base film (F _O ) and other films adhered to the panel member (P) do not include the defective portion (B). 4, the defective portion B of the film material F on which the defective mark is marked is recovered by the recovery unit 80 together with the release film F _R and the reinforcing film F _S do.

Here, the suction 63 and the support 65 have the same structure as that of the suction and support provided in the general laser device, and therefore, a detailed description thereof will be omitted.

The laser nozzle 61 irradiates the laser beam emitted from the laser generator (not shown) to the film fabric F to remove the release film F _R and the reinforcing film F _S from the base film F (F _O ) and other remaining films are laser cut selectively so as to have an area corresponding to the panel member (P). Here, the light amount of the laser is adjusted so that the release film (F _R ) and the base film (F _O ) other than the reinforcing film (F _S ) and other remaining films of the film fabric F can be selectively laser cut. Here, the reinforcing film F _S is formed of a material that is difficult to cut with laser, as described above. Thus, the technical limitations, the film fabric (F) thickness error, and because of the cause of the vibration of the film fabric (F) a release film (F _R) of the light amount adjustment of the laser as shown in Figure 7 a portion of the Even if the laser is cut off, the reinforcing film F _S is kept in a circular shape without laser cutting.

On the other hand, the laser nozzle 61 can be configured to control the laser cutting aspect by a cutting surface detecting sensor 67 for detecting the cutting surface T of the base film (F ₀ ) and other films that have been laser cut. The cutting face detection sensor 67 may be a conventional vision system or a photo sensor or a proximity sensor for photographing a cut surface T of a laser cut base film F _o and other films to confirm the cut surface T Lt; / RTI >

6, the cut surface detecting sensor 67 detects the cut surface (T) of the base film (F ₀ ) and other films that are transferred to the peeling / attaching unit 70 after laser cutting by the laser nozzle 61 ), And applies a cut signal to the control unit with respect to the cut aspect of the base film (F ₀ ) and other films. The control unit of the base film (F _O) Other film cutting plane (T) and the laser nozzle film fabric which laser is irradiated (F) laser irradiation to make the distance between the point the laser nozzle 61 with a discharge (61) of And controls the driving. Accordingly, the laser nozzle 61 can be laser cut to a base film (F _O) are loaded with other panel members (P) and so as to have an area corresponding to the preset of the base film (F _O) Other film length. That is, the laser nozzle 61 can laser cut the base film (F _o ) and other films to have a predetermined length by the cut surface detecting sensor 67.

The number of the cut surface detecting sensors 67 is not particularly limited. For example, as shown in FIG. 6, when the base film (F _O ) and other films are laser-cut to have a length of 20 inches or 24 inches, a laser-cut base film (F _O A first detection sensor 67a for detecting the cut surface T of the other films and a base film F _{o for} laser cutting to have a length of 24 inches and a second detection sensor 67b may be installed.
