Description of the invention: [Technical field to which the invention pertains] The present invention relates to a laser cutting device and a semi-cutting process for processing a polarizing film of a step-domain film of the prior art with the laser cutting device, or =: It: Perform = cut, but since it is cut = spare. Since the foreign matter is mixed into the polarizing film, the yield is caused by the contact of the film in recent years. In the case of cutting with a laser and cutting with a blade, it is difficult to generate foreign matter such as scrap from the cut object. Thereby, the decrease in the yield can be suppressed. Therefore, the cutting method is extremely flawed, and the method of arbitrage (for example, "previous technical literature"). [Patent Document] 曰本特开曰本特开 [Patent Document 1] Japanese Open Patent Gazette 2008-302376 STATEMENT (Publication of the publication of the Japanese Patent Publication No. 2), Japanese Patent Publication No. 2009-22978 (published on Feb. 5, 2009). Problem] However, the polarized thin film of the relative movement of the polarizing film caused by the above-mentioned previous lasers is generated, and the money is generated; ^good turn' is the case of using the low side of the laser, because the laser output is There is a problem that it is impossible to make a proper cut. The ear '疋' is specifically described below. In the case of cutting the transported polarizing film, the cut 201221262 large f-segment is carried out while carrying the polarizing film with a certain degree of difficulty. In order to increase the production rate, the above-mentioned constant speed is, for example, a speed of about 50 m/s. Therefore, from the viewpoint of improving the yield, the polarizing film is cut at the time of acceleration before and after the constant speed and at the time of deceleration. In the stage where the light film is transported at a relatively fast speed, the energy per unit time of the laser beam is reduced. Therefore, it is necessary to increase the output of the laser required for cutting. On the one hand, in the stage where the transfer speed of the polarizing film is slow, the energy per unit time of the f-ray portion is increased. As a result, there is a possibility that the quality of the surface of the polarizing film deteriorates due to excessive heat. Therefore, it is necessary to suppress the output of the laser. Here, in order to suppress the output of the laser, there is a problem that the oscillation of the laser is unstable in the use of the low output side of the laser. Therefore, in the adjusted irregularity fluctuation of n = (fluetuatiGn), there is no possibility of illuminating the thin film after cutting, so we require that even at a stage where the conveyance speed is slow, the quality of the cut surface is deteriorated, and the polarizing film is cut. The Thunder is related to such a problem. In Patent Document 2, there is disclosed a laser processing method t. The processing speed of the processed object and the laser light is reduced, and the laser is reduced by a factor of two. According to the technique, the cause can be avoided. The laser oscillator: the output laser power is increased, and the etching phase == it is necessary to increase the relative speed of the workpiece and the laser light, which may be difficult to be fine. The output of the film is not unstable, and will not cause polarizing thin [the means to solve the problem] Laser ΐ ϋ ϋ 射 射 射 射 射 射 射 射 射 射 射 射 射 射 射 射 射 射 射 射 为了 为了 为了 为了 为了 为了 为了 为了 为了 为了 为了 为了 为了 为了 为了 为了 为了 为了 为了 为了The oscillating laser light is reflected to the polarized light 201221262. The dipole system is disposed between the polarized _ and the curved mirror, and the above-mentioned illuminating light is condensed, and the 雷 Ι Ι Ι Ι 与 与 与 与 与 与 与 与The transmitted light splits into a two-shot filament _. _, even:: ί = The relative speed of the laser light-cutting and cutting device and the polarizing film of the village is reduced by the use of the laser _ vibration, which can be obtained because When the occlusion of the p8p Γ side becomes an advantageous output stability, the energy of the polarizing film is reduced by the use of the upper ii, so that the cutting surface which becomes a problem when the side of the surface of the first sewing machine is turned off can be suppressed. The quality is inferior [invention effect] machine, line, called - laser _ two, mirror 'secret through the laser light film of the laser vibrating machine, between the curved mirror, and # concentrating lens, the system is configured in partial Protecting; ^taking, music, and concentrating the above-mentioned laser light', in which the above-mentioned bending, that is, lightning = injury, causes the above-mentioned laser light to pass through and reflect. In the case where the speed of the high-transmission coffee film is small, the energy of the polarizing film is small, so that it is possible to achieve the problem of suppressing the deterioration, and the problem is that the quality of the cut surface is the same as the quality of the cut surface [embodiment] == one The embodiment will be described below based on the first to fourth figures. - ΪΓ〇 3 is a cross-sectional view of the laser cutting position 10 of the present invention. The laser cutting and receiving device 10 includes a laser oscillating machine 1, a beam expander 2, a curved mirror 3, a minute ^21121262, and a condensing lens 5. The laser light oscillating machine 1 makes the laser light oscillate and can be used, for example, c〇2 laser (carbon dioxide laser), uv laser, guided YAG laser, excimer laser, and the like. Among these, it is preferred that the high-transmission film is cut into a suitable co2 laser. The T1 field is particularly prone to instability due to the low output of the laser oscillator 1 . ^This: The output is preferably a high output. On the other hand, when the output is too high, quality deterioration occurs on the cut surface of the polarizing film due to excessive thermal expansion or the like: The specific output of the laser oscillator 1 can be adapted to the transport speed of the polarizing film 6 of the polarizing film 6 and the spectroscope described later. 4 It is suitable to adjust to the transmission and reflection. From these viewpoints, the output of the laser light-vibration is more than the shoulder and 4GGW or less. In addition, the output of the 'laser light vibration machine' is unstable, but in particular, if it is less than 3 〇w, the inclination is unstable. The frequency of the laser light to be irradiated can be appropriately changed depending on the output of the laser oscillator i, the thickness of the polarizing film 6, and the transport speed of the polarizing film, but it can be approximately 5 kHz or more and 10 kHz or less. The laser cutting device 10 is provided with a beam expander 2 as an appropriate form. The beam expander 2 is a member that expands the g-light into a parallel beam, and a well-known beam expander can be used. The diameter of the laser light L1 is expanded by the beam expander 2 to, for example, 2 times to 1 〇/^ left to become the laser light L2. When the laser light L6 is irradiated to the polarizing film 6, the laser light is easily focused by expanding the diameter of the laser light. The curved mirror 3 reflects the laser light oscillated from the laser oscillator 1 to the member of the polarizing film 6. The laser cutting device 1 is provided with one curved mirror 3. However, if the laser light L2 is used as the laser light L3 and is reflected to the polarizing film 6, it may be plural. The output of the laser oscillating machine in a general laser cutting device will be described using the second figure. The second graph shows a graph of the relationship between the time t and the output w of the laser oscillator when the polarizing film is transported. When the polarizing film is conveyed while being cut, the polarizing film is first accelerated (acceleration region), and then set to the 201221262 region), so that the polarizing film is slow (deceleration region), in the acceleration region and the deceleration region, due to the polarizing film. The speed is reduced, so as long as it is the same riding condition, the amount of each of the singles is increased. Because it is necessary to reduce the output of the laser vibrator. Therefore, in the acceleration region and the portion of the subtraction 2 field, the transmission of the laser light (four) machine is unstable (unstable region). As a result, in the acceleration region and the deceleration region, due to the laser The output of the filament machine is not flawed, but may result in no _. The above-mentioned limit 'is difficult to set in the general laser, in the acceleration zone and the deceleration zone, and can not & the output of the south laser light disc machine. *, Na Fang, in the invention of the laser cutting device 10, in the curved mirror 3 and the poly; preparation beam splitter 4. The beam splitter 4 is the above-mentioned laser light [3 through the knowledge of the split light 11. Laser light u _ by the beam splitter and the knives are the laser light 14 that is transmitted light and the laser light that is reflected light. The ratio of the laser beam that transmits and reflects the laser beam is not particularly limited, and the output of the λ λ f machine 1 is not limited. The thickness of the polarizing film 6 and the transport speed of the polarizing film 6 are suitably adjusted to be ideal. In general, the case of '_beaming laser light' below _w can be appropriately used to detect the polarized light (4), 疋In the laser cutting device 10, the laser beam 4 is used to cause the laser to emit light. The polarizing film 6 is cut; and the energy is reduced according to i first, that is, even in the acceleration region, the light can be used in the high output, and the laser light can be used to illuminate the laser light. On the one hand, because of the time H Yang rides on the polarized light _ can ^ ^ with the laser light vibrating and the high output side becomes a problem in the cutting surface = laser light L5 due to the condenser lens 5 It is condensed on the polarizing film 6. The condensing lens 5 and 201221262 are not particularly limited. A spherical lens, an aspheric lens, or the like can be used. Since the condensing diameter of the JL6 can determine the cutting width, the laser light is finely polarized. The concentrating film of L6 is difficult to be in the upper part, and is more than 400 μm. In addition, in the case of the polarizing film 6 which is the object of the cutting of the laser cutting device 10, a well-known polarizing film can be used. In the case of a polarizing film, a light film is generally used, but a short or plate-shaped polarizing film may be used. The length of the polarizing film 6 in the cutting direction is 1 〇 m 2 m or more, less than the plate, and the plate-like system.

The total thickness of the light gamma 6 and the finer silk is mosquito, but the upper: 5_m or less. Further, in the polarizing film 6, the Shentianzi of the polarizing film 6 is generally 1 〇μΐΏ or more and 5 〇 or less. Furthermore, in the range where the polarizing thin is not problematic, in addition to the above three layers, it is also possible to use a poly-film and poly-terephthalic acid to protect the thickness and width of the film. There is no particular limitation. ^ From the viewpoint of using the protection as a polarizing _, it is possible to appropriately use, for example, the thickness of the film thief, the cutting of the polarizing film 6 caused by the width laser cutting device 10 below the 15 (8) plane, and the side of the film. Moving the laser 201221262 = view, 彳 is fine to form the cut. In addition: the moving surface of the polarizing film-face is separated from the government and is placed in the shape of the polarizing film 6. The yarn is cut into the cut yarn, which is good for stable (four) cutting. work. Qiu Ba η engraved "cutting 1" polarizing film" means that the "at least σ." of the polarizing film is also included in the pre-twisting degree of the polarizing film, and is also included in the "cutting" behavior. , s; 7; seeking [cutting machine] The cutting machine 2q of the present invention will be described. The third® represents a cross-sectional view of the invention $ strip = 20. The slitting machine 2 includes: a laser cutting device ι, a winding σ, a transport roller 12 · 12a · 12b · 12c · 12d · 12e · 12f (hereinafter referred to as "2 to 12fj", a length gauge 14, and a winding portion 13& (10). The long-shaped polarizing film 6 is fed, and the conveyance roller 12 is rolled up. In the case of the roll: Chuan, there is no _ limit, and the roll of the knowledge can be sent to the slitter 20 system. The cylindrical shaft serves as the winding portion u, and the paper tube or the plastic tube around which the polarizing film 6 is wound can be held. The side surface of the winding sheet is not shown, and j is provided with a rotating device for rotating the winding portion 11, The winding portion is rotated and the polarizing film 6 is wound in the conveying direction. The tension applied to the polarizing film 6 and the conveying speed of the film can be set by the rotating device. The position of the horizontal direction of the winding portion 11 can be appropriately adjusted. The π winding portion 11 is provided at one place, but may be provided at two places like the winding portion 13 & 131. Before the polarizing film 6 of the feeding portion u is completely wound, it can be connected to the polarizing film of the other winding portion, and the time for changing the polarizing film before processing can be reduced. In the slitter 20, the conveyance rollers 12 to 12f are disposed along the conveyance path of the polarizing film 6.
