Field of the Invention The present invention relates to a film roll cutting device using laser light, and more particularly to a film roll cutting device for cutting a polarizing film roll using laser light. [Prior Art] Generally, a liquid crystal display includes a liquid crystal panel as an essential component. The liquid crystal panel is composed of a pair of transparent insulating substrates each having a liquid crystal layer and an electric field interposed between the liquid crystal layers and facing each other. electrode. The directionality of the liquid crystal molecules can be manually adjusted by changing the electric field between the electrodes by changing the electric field. In this process, different images are displayed using variable optical transmission. The liquid crystal directionality of the liquid crystal display can be changed to a visible polarizing film, which is provided on the upper and lower surfaces of the liquid crystal panel, respectively. The degree of light transmission of the liquid crystal display can be determined according to the arrangement of the transmission axes of the polarizing film (the upper and lower surfaces of the liquid crystal panel) and the alignment characteristics according to the liquid crystal. A roller type polarizing film (hereinafter, simply referred to as "polarizing film roll") is produced by a well-known method 'should be based on the size of the corresponding liquid crystal display, through a mechanical cutting machine (for example, a cutting press or an ultrasonic cutter) (super cutter)) performs cutting. 201204501 However, in the case where the polarizing film roll is cut using a mechanical cutting machine such as a punching machine or an ultrasonic cutter, the cutting surface should be chamfered, resulting in a large amount of dust that causes additional program and environmental costs, resulting in increased production.

Generally, a film roll cutting device that uses a laser light-cut film roll (e.g., a polarizing film roll) is provided to cut the film roll when the entire laser-related system of the roll film cutting device moves in the length and width direction of the film roll. The conventional film roll cutting device has a problem that the cutting precision and the high-speed machining capability are degraded when the laser-related system is completely moved.

However, in the laser cutting device that cuts the film roll when the laser beam source is fixed and the head module moves, when the distance L between the laser beam source and the head module increases, 'the laser beam reaches the surface of the film roll. The angle changes, which changes the intensity of the laser beam. Therefore, if a conventional laser cutting apparatus is used, the cut surface of the film roll may have different states, which deteriorates the reliability of the cutting process. In addition, films (sheets) cut by conventional laser cutting equipment may be susceptible to bending.

The first optical reflecting unit 126 has the function of a polarized laser control unit that changes the angle of the laser beam output from the laser beam source 122, which is linearly polarized by the 201204501 component. For this purpose, the first optical reflecting unit 126 has a reflector that causes the laser beam source 22 to output a laser beam B whose linear polarization component is tilted from a vertical state by a predetermined polarization angle with respect to a vertical line. The second optical reflecting unit 128 has the function of a laser beam transmitting unit to transmit the laser beam output from the first optical reflecting unit 126 to the laser nozzle 129. The second optical reflecting unit 128 has a reflector that transmits the laser beam B output from the first optical reflecting unit 126 to the third optical reflecting unit 121. The third optical reflecting unit 121 has a horizontal reflector that reflects the laser beam output from the laser beam source 122 in a horizontal direction. The laser receiving unit 127 mounted to the head module 125 has a vertical reflector that reflects the laser beam reflected from the third optical reflecting unit 丨 21 in a vertical direction toward the laser nozzle 129. According to a specific example, a film roll cutting device 1A for laser light is used, including a beam collimating member 18'' disposed between the laser beam source 22 and the third optical reflecting unit 121, so that the laser beam source 122 is provided. The output laser beam is collimated into a parallel beam. The head module 125 is disposed as a vertically moving block 118 which is coupled to the linear motor 111 such that the laser nozzle 129 faces the film roll F. The head module 125 can be configured not only to move in the width direction of the film roll F but also to move in the length direction if necessary, as is apparent to those skilled in the art. The frame 110 includes a base 112, a plurality of support frames 114 coupled to the base 112, and a main frame 116 mounted to the support frame 114. A conveyor belt (not shown) that transports the polarizing film separated from the film roll F is disposed in the 201204501 internal space of the main frame 116. Further, the main components of the above laser cutting machine are mounted on the upper surface of the main frame 116. A conveying device (not shown) for conveying the film roll and a vacuum suction device for adsorbing the roll of the film to be fixed are attached to the frame. Further, a by-product removal device (not shown) for removing by-products generated when the film roll is cut is attached to the frame. Figure 4 is a schematic illustration of an example of the beam collimating member of Figure 3. Referring to FIG. 4, the beam collimating member includes a convex lens unit 182 for focusing the laser beam output 22 of the laser beam source output; a concave lens unit 184 is spaced apart from the convex lens unit 182 by a predetermined distance and passed through The path of the laser beam of the lenticular lens unit 182 is offset, causing the focused beam to become a parallel beam. Fig. 5 is a schematic cross-sectional view showing the entire structure of a circular 4-beam collimating member. Referring to Fig. 5', the beam collimating member 18'' includes a first chamber 18'' and a second chamber 183' which have a hollow tube shape and are screwed to each other. The first compartment 181 has a first coupling unit 丨 83 disposed on an outer peripheral surface of either end thereof to be screwed into the second coupling unit 187 of the second compartment 183. The first chamber 181 houses a convex lens of the convex lens unit 182, and the convex lens has two convex surfaces. To this end, the first chamber 181 has a first insertion portion 81 that accommodates a convex lens that protrudes from the inner bore. The double sides of the convex lens are adjusted by a pair of first fixing nuts 186, and the outer sides of the first fixing nut 丨 86 are respectively threaded so that the threads 83 formed in the holes of the first chamber 181 are engaged therewith. The second compartment 183 has a second coupling unit 187 disposed on an inner peripheral surface of either end thereof such that the second coupling unit 187 can be screwed with the first coupling unit 185 of the first compartment 201204501 181. The second compartment 183 houses a concave lens of the concave lens unit 184 having two concave surfaces. To this end, the second compartment 183 has a second insertion portion 85 that receives a concave transparency that protrudes from the inner bore of the second compartment 183. The double sides of the concave lens are adjusted by a pair of second fixing nuts 188, and the outer sides of the second fixing nut 188 are respectively threaded so that the second thread formed in the inner hole of the second chamber 183 can be engaged therewith. Although it has been explained that the first coupling unit 185 of the first chamber 181 has a male thread and the second coupling unit 187 of the second chamber 183 has a female thread, they can still be configured in the opposite manner, as is generally known in the art. Obvious skill. The circle 6 is a cross-sectional view of another example of the beam collimating member of Fig. 4. Elements in Figure 6 that are the same as the 囷5 component symbol indicate the same components having the same function. Referring to the circle 6, the beam collimating member 280 according to the modified specific example includes: a convex lens unit 285 having a pair of convex lens sheets 282 and 284 each having a flat surface which is spaced apart from each other and faces each other; A concave lens unit 287 has a pair of concave lens sheets 286 and 288 each having a flat surface which is spaced apart from each other and faces each other. In other words, the beam collimating member 280 according to the present embodiment includes: the pitch maintaining protrusions 206 and 208, which are disposed at the first insertion portion 202 of the first chamber 281 and the second insertion portion of the second chamber 283 204 to maintain the spacing between the convex lenses 282 and 284 and the concave lenses 286 and 288. The laser beam B outputted from the laser beam source 122 at a predetermined scattering angle changes its path to the focusing direction when passing through the convex lens unit 182; when it passes through the concave lens unit 184, it changes its direction of divergence. The path becomes a parallel beam. Fig. 7 is a schematic view showing the configuration of a laser system according to a specific embodiment; the circle 8 is a schematic diagram of a parallel beam generated between the third optical reflecting unit and the laser receiving unit in Fig. 7. For example, the laser beam outputted from the laser beam source 丨 22 as shown in FIG. 8 changes to a parallel beam when passing through the beam collimating member 180, and the parallel beam is at the same intensity in the third optical reflecting unit 121. The laser receiving unit 127 transmits 'therefore the distance L between the third optical reflecting unit 121 and the laser receiving unit 127 (mounted on the head module 125' head module 125 from the third optical reflecting unit 121) The laser beam can be maintained at the same intensity. Therefore, the cutting surface of the film roll F can be uniformly processed, and the reliability and the cutting quality of the cutting process can be improved. In other words, since the intensity of the beam B1 varies depending on the distance between the horizontal reflector and the vertical reflector, the laser system generally has no beam collimating component, as shown in Fig. 1, depending on the distance L. Different degrees of film processing. However, if a beam collimating member is employed in the laser system, as disclosed in the present disclosure, the intensity of the beam B does not change depending on the distance between the third optical reflecting unit 121 and the laser receiving unit 127, and thus can be uniformly The cut surface of the film roll F is processed. Further, the film roll cutting device 100 using laser light according to a specific embodiment processes the film roll to have a uniform cutting surface, which prevents the edge of the cut film or film roll from being bent', thereby improving the quality of the cut film. 201204501 The above description and the accompanying drawings illustrate the preferred embodiments of the present invention, and it is understood that various additions, modifications, and combinations can be made without departing from the spirit and scope of the appended claims. / or alternatives can be used.
