Description

Technical Field

[0001] The present invention relates to a film processing system for cutting a film using a laser beam. Background Art

[0002] An existing film processing system for laser cutting a film to manufacture a product includes: a laser head for releasing a laser beam; a head driver for moving the laser head in at least one of a length direction and a width direction; and a fixing fixture for vacuum adsorbing and fixing the film.

[0003] This existing film processing system uses a laser head to irradiate a laser beam onto a film, and uses a head driver to move the laser head along a laser cutting path corresponding to the contour of a product to laser cut the film along the laser cutting path, thereby separating the film into products.

[0004] Figure 1 This is a diagram showing a schematic structure of a fixing jig included in a conventional thin film processing system.

[0005] However, if Figure 1 As shown, the fixing fixture 100 of the existing film processing system includes: a placement plate 102, on the upper surface of which the film F is placed; a plurality of adsorption holes 104, which are formed at preset intervals on the upper surface of the placement plate 102 so that the film F can be vacuum adsorbed and fixed at a preset position of the placement plate 102; and a protective groove 106, which is recessed and formed on the upper surface of the placement plate 102 along the laser cutting path, so as to prevent the placement plate 102 from being damaged by the laser beam that cuts the film F along the laser cutting path and penetrates.

[0006] In such an existing film processing system, when it is necessary to change processing conditions related to the size and shape of the film F, the size and shape of the product, the number and position of the adsorption holes 104, and the size and shape of the protection groove 106, the existing fixing jig 100 can only be changed to another fixing jig 100 having the number and position of the adsorption holes 104 and the size and shape of the protection groove 106 corresponding to the processing conditions. Therefore, in the existing film processing system, when manufacturing a variety of products with different processing conditions, it is necessary to have a variety of fixing jigs 100 with different numbers and positions of resins of the adsorption holes 104, the size and shape of the protection groove 106, etc. In this regard, the existing film processing system has the following problems: it costs a lot to have the fixing jig 100, and the replacement operation of the fixing jig 100 takes a long time. Summary of the invention

[0007] The present invention is used to solve the problems of the prior art. The purpose of the present invention is to provide an improved film processing system so that when the film is laser cut to form a product, the shape of the fixing fixture used to fix the film can be easily adjusted according to various processing conditions.

[0008] A film processing device of a preferred embodiment of the present invention for solving the above-mentioned problem performs laser cutting on a film sheet to form a product, and comprises: an XY stage having a plurality of fixing clamps and a transfer machine, wherein the plurality of fixing clamps are used to fix the film sheet, and the transfer machine transfers the plurality of fixing clamps along at least one of a length direction and a width direction; and a cutting machine, irradiating a laser beam to the film sheet fixed on the XY stage to separate the film sheet into the above-mentioned product, wherein the plurality of fixing clamps comprises: a clamp body; a plurality of adsorption sheets, which are detachably coupled to the clamp body so that the film sheet can be placed in a state separated from the clamp body in a height direction, and the film sheet is fixed by vacuum adsorption; and a protective groove, which is formed in a groove shape surrounded by the outer side surfaces of the plurality of adsorption sheets and the upper surface of the clamp body, and is formed between the plurality of adsorption sheets so that the laser beam passing through the film sheet is incident when the film sheet is laser cut.

[0009] The present invention relates to a film processing system, and when a film sheet is transferred or laser cut to form a product, the shape of a multi-fixing fixture that fixes the film sheet in a manner that prevents it from moving can be adjusted according to processing conditions by a simple operation of assembling and disassembling a plurality of adsorption sheets of the multi-fixing fixture. Therefore, in the present invention, the film sheet can be laser cut according to a variety of processing conditions without replacing the multi-fixing fixture itself, and the cost required for individually preparing a plurality of fixing fixtures that are only applicable to specific processing conditions and the time required for the replacement operation of the fixing fixtures can be reduced.

[0057] Figure 2 A top view showing a simplified structure of a thin film processing system according to a preferred embodiment of the present invention is shown in FIG. Figure 3 for Figure 2 Side view of the thin film processing system shown.

[0058] Reference Figure 2 and Figure 3 The film processing system 1 of the preferred embodiment of the present invention may include: a feeder 10 for feeding a film fabric F0; a first cutting machine 20 for laser cutting the film fabric F0 to form a film sheet F1; an XY table 30, the shape of which can be changed according to processing conditions, and the film sheet F1 is fixed to prevent it from moving and is transferred along a preset path; a first moving machine 40, which transfers the film sheet F1 from the first cutting machine 20 to the XY table 30; a second cutting machine 50, which irradiates a laser beam LB to the film sheet F1 transferred through the XY table 30 to laser cut the film sheet F1 to form a product P; a loader 60, which is used to load the product P; and a second moving machine 70, which transfers the product P from the XY table 30 to the loader 60.

[0059] There are no particular restrictions on the types of film fabrics F0 that can be laser cut using the film processing system 1 and the types of products P that can be cut from the film fabrics F0. For example, the film fabrics F0 can be polarizing films or functional films, and the products P can be displays, dashboards, etc., installed in mobile products, electric vehicles, etc.

[0060] First, the feeder 10 is a device for feeding a film fabric F0 for manufacturing a product P.

[0061] The structure of the feeder 10 is not particularly limited. Figure 3 As shown, the feeder 10 may include an unwinder 12, a feed roller 14, a conveyor 16 for the fabric, and the like.

[0062] The unwinding machine 12 unwinds the film fabric F0 that has been previously wound in a roll state, and supplies the film fabric F0 along the longitudinal direction (hereinafter referred to as “longitudinal direction”).

[0063] The feed roller 14 is spaced apart from the unwinder 12 along the + length direction, and intermittently supplies the film fabric F0 transferred from the unwinder 12 along the + length direction according to a preset reference length L1.

[0064] The fabric conveyor 16 is spaced apart from the feed roller 14 along the + length direction so as to support the film fabric F0 , move the film fabric F0 passing through the feed roller 14 along the + length direction and transfer it to the first cutting machine 20 .

[0065] Figure 4 This is a diagram showing the state in which a film sheet is separated from a film web.

[0066] Next, the first cutting machine 20 is a device for laser cutting the film material F0 supplied from the supply machine 10 to separate the film material F0 into film sheets F1 having a predetermined shape.

[0067] The structure of the first cutting machine 20 is not particularly limited. Figure 2 As shown, the first cutting machine 20 may include a cutting plate 22, a laser oscillator (not shown), a first laser head 24, a first head driver 26, and the like.

[0068] like Figure 3 As shown, the cutting board 22 is spaced apart from the fabric conveyor 16 along the + length direction so that the film fabric F0 passing through the fabric conveyor 16 can be placed on the upper surface of the cutting board 22.

[0069] The cutting plate 22 is formed through the film fabric F0 along the width direction (hereinafter referred to as the "width direction") at a position separated from the front end of the film fabric F0 placed on the cutting plate 22 by a reference distance L1 along the -length direction, and has a suction hole 22a for sucking and removing the smoke (fume) and other foreign matter generated when the film fabric F0 is cut by the laser beam LB. In this case, preferably, a vacuum pump 28 and a vacuum component are provided on the lower surface of the cutting plate 22 to provide negative pressure for sucking the foreign matter to the suction hole 22a, but it is not limited to this.

[0070] A laser oscillator (not shown) generates and oscillates a laser beam LB for cutting the film fabric F0.

[0071] like Figure 3 As shown, the first laser head 24 can irradiate the laser beam LB transmitted from the laser oscillator to the film fabric F0 placed on the cutting board 22.

[0072] Furthermore, a reflection mirror or other optical components (not shown) for transmitting the laser beam LB oscillated from the laser oscillator to the first laser head 24 may be provided between the laser oscillator and the first laser head 24 .

[0073] like Figure 2As shown, the first head driver 26 is arranged to cross the film fabric F0 placed on the cutting plate 22 in the width direction, and can move the first laser head 24 in the width direction. For example, the first head driver 26 may have a first sliding portion 26a that moves in the width direction by a driving motor or other driving components. In this case, the first laser head 24 can move in the width direction along the first sliding portion 26a and can be coupled to the first sliding portion 26a in a manner facing a position of the film fabric F0 separated from the front end of the film fabric F0 by a reference length L1 in the -length direction.

[0074] like Figure 3 As shown, according to the first cutting machine 20, the film fabric F0 is placed on the cutting plate 22 in such a manner that the front end of the film fabric F0 is separated from the suction hole 22a by a reference length L1 in the + length direction, and the laser beam LB is irradiated to the film fabric F0 by the first laser head 24, and at the same time, the first laser head 24 is moved in the width direction by the first head driver 26, so that the film fabric F0 can be laser cut in the width direction. Figure 4 As shown, the first cutting machine 20 can cut the film fabric F0 into film sheets F1 having a length equal to a reference length L1 and a width equal to the width of the film fabric F0 .

[0075] Figure 5 A top view showing a simplified structure of a multi-fixing fixture is shown below. Figure 6 is a cross-sectional view showing a state where a plurality of suction sheets are separated from a jig frame, Figure 7 This is a cross-sectional view of a state where a plurality of adsorption sheets are combined with a fixture frame. Figure 8 It is a cross-sectional view of a state where a plurality of suction sheets having different areas are combined with a jig frame.

[0076] Next, the XY stage 30 is a device for fixing and transferring the film sheet F1 transferred from the first cutting machine 20 .

[0077] The XY stage 30 can transfer the film sheet F1 transferred from the first cutting machine 20 via the first moving machine 40 in at least one of the length direction and the width direction while fixing the film sheet F1 to prevent it from moving. Figure 4 As shown, the XY stage 30 may include a first stage 32, a second stage 34, and so on.

[0078] The first stage 32 can reciprocate along the width direction while fixing the film sheet F1 transferred from the first cutting machine 20 via the first moving machine 40. Figure 4 As shown, the first stage 32 may include a plurality of fixing fixtures 32a, a first transfer machine 32b, and the like.

[0079] The multiple fixing fixtures 32a can fix the film F1 by vacuum adsorption, and the shape thereof can be adjusted according to at least one of the processing conditions including the size and shape of the film F1 and the size and shape of the product P. For this purpose, Figure 5 As shown, the multi-fixing fixture 32a may include a fixture frame 32c, a plurality of suction sheets 32d, a protection groove 32e, and the like.

[0080] The clamp frame 32c may be in the shape of a flat plate having a predetermined area, and may be extended in a long manner along the horizontal direction. Figures 5 to 7 As shown, the clamp frame 32c may include a plurality of vacuum holes 32f, a plurality of suction holes 32g, a connecting flow path 32h, and the like.

[0081] A plurality of vacuum holes 32 f are formed at a preset interval on the upper surface of the jig frame 32 c so as to detachably couple one of the plurality of suction sheets 32 d .

[0082] The coupling structure of the plurality of vacuum holes 32f and the plurality of suction sheets 32d is not particularly limited. For example, the plurality of vacuum holes 32f may include internal threads 32i formed on the inner circumference so as to be screwed to the suction sheets 32d.

[0083] The plurality of vacuum holes 32f can transmit negative pressure transmitted from a vacuum pump or other vacuum components (not shown) to the suction sheet 32d coupled to the vacuum hole 32f.

[0084] A plurality of suction holes 32g are formed at a preset margin interval on the upper surface of the jig frame 32c so as to be spaced apart from the plurality of vacuum holes 32f at a preset interval.

[0085] The plurality of suction holes 32g can respectively use negative pressure transmitted from a vacuum pump or other vacuum components (not shown) to suck in and remove fume and other foreign matter generated when the film sheet F1 is cut by laser.

[0086] The connecting flow path 32h is formed inside the clamp frame 32c so that the plurality of vacuum holes 32f and the plurality of suction holes 32g can be connected to a vacuum pump or other vacuum components (not shown) that provide negative pressure. According to the connecting flow path 32h, with the plurality of adsorption sheets 32d as a medium, negative pressure for vacuum adsorption of the film sheet F1 can be applied to the plurality of vacuum holes 32f through the connecting flow path 32h, and negative pressure for adsorbing and removing foreign matter can be applied to the plurality of suction holes 32g through the connecting flow path 32h.

[0087] On the other hand, preferably, the connecting flow path 32h for connecting the plurality of vacuum holes 32f and the vacuum component and the connecting flow path 32h for connecting the plurality of suction holes 32g and the vacuum component are formed separately in the jig frame 32c. In this case, negative pressure can be applied to the plurality of vacuum holes 32f and the plurality of suction holes 32g separately, thereby vacuum adsorption of the film sheet F1 by the plurality of vacuum holes 32f and the plurality of adsorption sheets 32d and removal of foreign matter by the suction holes 32g can be separately performed.

[0088] like Figures 5 to 7 As shown, the plurality of adsorption sheets 32d may respectively include a sheet body 32j, a coupling portion 32k, adsorption holes 32l, and the like.

[0089] The sheet body 32j has the same height as the reference distance L2 so as to support the film sheet F1 while being spaced apart from the upper surface of the clamp frame 32c by a predetermined reference distance L2 in the height direction of the film sheet F1 (hereinafter referred to as "height direction").

[0090] The shape of the sheet body 32j is not particularly limited, and the sheet body 32j may be in the shape of a block having a polygonal or circular cross-sectional shape. For example, the sheet body 32j may be in the shape of a block having a quadrilateral cross-sectional shape.

[0091] Such a sheet body 32j has a cross-sectional area larger than a predetermined reference area so as to stably support the film sheet F1 placed on the upper surface of the sheet body 32j by the first moving machine 40 described later.

[0092] Furthermore, the plurality of sheet bodies 32j provided on the plurality of adsorption sheets 32d may also have different cross-sectional areas or shapes. Figure 8 As shown in FIG. 1 , the cross-sectional area of ​​the plurality of sheet main bodies 32j of the plurality of suction sheets 32d for supporting the central region of the film sheet F1 may be larger than the cross-sectional area of ​​the plurality of sheet main bodies 32j of the plurality of suction sheets 32d for supporting the edge of the film sheet F1. That is, in consideration of the characteristics of the setting positions of the plurality of suction sheets 32d, the cross-sectional area or shape of the plurality of suction sheets 32 at each setting position of the plurality of suction sheets 32d is different.

[0093] like Figure 6 As shown, the coupling portion 32k may extend from the lower surface of the sheet body 32j in the -height direction so as to be coupled to one of the plurality of vacuum holes 32f of the jig frame 32c.

[0094] Such a coupling portion 32 k has a cylindrical shape having a diameter corresponding to the diameter of the vacuum hole 32 f so as to be inserted into the vacuum hole 32 f , and a height equal to or smaller than the depth of the vacuum hole 32 f .

[0095] Furthermore, when the internal thread 32i is formed on the inner circumferential surface of the vacuum hole 32f, the external thread 32m that can be screwed with the internal thread 32i of the vacuum hole 32f is formed on the outer circumferential surface of the coupling portion 32k. Figure 6 and Figure 7 As shown, the outer thread 32m of the coupling part 32k is screwed into the inner thread 32i of the vacuum hole 32f to couple the coupling part 32k to the vacuum hole 32f, so that the plurality of adsorption sheets 32d can be detachably coupled to one of the vacuum holes 32f. Thus, the plurality of adsorption sheets 32d can be provided on the upper surface of the clamp frame 32c so that the film sheet F1 can be supported by the sheet body 32j.

[0096] like Figure 6 and Figure 7 As shown, the adsorption hole 321 is formed in a manner that penetrates the sheet body 32j and the coupling portion 32k in the height direction, and can be connected to the vacuum hole 32f when the coupling portion 32k is coupled to the vacuum hole 32f. Thus, the adsorption hole 321 can use the negative pressure transmitted from the vacuum hole 32f to vacuum adsorb and fix a region of the film sheet F1 placed on the upper surface of the sheet body 32j by the first moving machine 40.

[0097] like Figure 7 As shown, the protection groove 32e may constitute a space between the plurality of suction sheets 32d surrounded by the outer side surfaces of the plurality of suction sheets 32d and the upper surface of the jig frame 32c.

[0098] The protective groove of the fixing fixture provided in the existing film processing system is directly recessed on the upper surface of the fixing fixture. However, the multiple fixing fixtures 32a of the film processing system 1 are combined on the upper surface of the fixture frame 32c, so that the multiple adsorption sheets 32d used to support and fix the film sheet F1 form a height difference structure, and there is no need to separately recess the upper surface of the fixture frame 32c to form the protective groove 32e, and the space between the multiple adsorption sheets 32d can be used as the protective groove 32e.

[0099] The protection groove 32e has a groove shape in which the outer side surfaces of the plurality of suction pieces 32d form the inner side surfaces of the protection groove 32e and the upper surface of the clamp frame 32c forms the bottom surface of the protection groove 32e, and the depth is the same as the height of the suction piece 32d.

[0100] According to the multi-fixing fixture 32a, the plurality of suction sheets 32d are selectively combined with one of the plurality of vacuum holes 32f or selectively separated from one of the plurality of vacuum holes 32f, thereby adjusting the number and position of the plurality of suction sheets 32d.

[0101] The number of suction sheets 32d refers to the total number of suction sheets 32d combined with the vacuum holes 32f, and the positions of suction sheets 32d refer to the positions of suction sheets 32d in the entire area of ​​the clamp frame 32c.

[0102] As described above, the staff can manually or use an automated device to perform the setting operation of the plurality of adsorption sheets 32d for adjusting the number and position of the plurality of adsorption sheets 32d. As described above, when the number and position of the plurality of adsorption sheets 32d are adjusted, the shape, depth, volume, position, etc. of the protection groove 32e can be automatically adjusted according to the adjusted number and position of the plurality of adsorption sheets 32d.

[0103] like Figure 2 As shown, the first transfer machine 32b can reciprocate the multi-fixing jig 32a and the film sheet F1 fixed to the multi-fixing jig 32a together in the width direction.

[0104] The structure of the first conveyor 32b is not particularly limited, and the first conveyor 32b may be composed of at least one of various conveying devices for reciprocatingly conveying the multiple fixing fixtures 32a in the width direction. Figure 4 As shown, the first transfer machine 32b may include a first linear rail 32n and a first linear motor 32o, etc.

[0105] The first linear rail 32 n is formed to be long and extended in the width direction, and is coupled to the second stage 34 .

[0106] The first linear motor 32o is mounted on the first linear rail 32n so as to be movable in the width direction, and is coupled to the lower surface of the clamp frame 32c so as to support the clamp frame 32c of the multi-fixed clamp 32a. The first linear motor 32o moves in the width direction along the first linear rail 32n, and transfers the multi-fixed clamp 32a and the film F1 fixed to the multi-fixed clamp 32a together in the width direction.

[0107] The first stage 32 can reciprocate the multi-fixing jig 32a and the film sheet F1 fixed to the multi-fixing jig 32a together in the width direction by the first transfer machine 32b while the film sheet F1 is fixed by the multi-fixing jig 32a.

[0108] like Figure 4 As shown, the second stage 34 can reciprocate the first stage 32 along the length direction. Figure 4 As shown, the second stage 34 may include a support plate 34a and a second conveyor 34b.

[0109] The support plate 34 a has a flat plate shape extending long in the width direction so as to support the first stage 32 .

[0110] The support plate 34a is combined with the first stage 32 in a manner that can support the first stage 32. For example, the first linear rail 32n of the first transfer machine 32b can be combined with the upper surface of the support plate 34a. Thus, the first transfer machine 32b can reciprocate along the width direction of the multi-fixing jig 32a and the film sheet F1 fixed to the multi-fixing jig 32a while being supported by the support plate 34a.

[0111] The second conveyor 34b can reciprocate the support plate 34a and the first stage 32 coupled to the support plate 34a together along the length direction.

[0112] The structure of the second conveyor 34b is not particularly limited, and the second conveyor 34b may be composed of at least one of various conveying devices that reciprocate along the length direction the support plate 34a and the first stage 32 coupled to the support plate 34a. Figure 4 As shown, the second transfer machine 34b may include a second linear rail 34c, a second linear motor 34d, and the like.

[0113] The second linear rail 34c is formed to extend long along the longitudinal direction.

[0114] The second linear motor 34d is mounted on the second linear rail 34c so as to be movable in the longitudinal direction, and is coupled to the lower surface of the support plate 34a so as to support the support plate 34a. The second linear motor 34d moves in the longitudinal direction along the second linear rail 34c, and can reciprocate the support plate 34a and the first stage 32 coupled to the support plate 34a in the longitudinal direction.

[0115] As described above, the second stage 34 can reciprocate the support plate 34a and the first stage 32 coupled to the support plate 34a along the longitudinal direction by using the second transfer machine 34b.

[0116] On the other hand, Figure 4 As shown, preferably, the second stage 34 is configured to reciprocate the support plate 34a and the first stage 32 coupled to the support plate 34a along the length direction between the preset sheet transfer position Ft and the preset product recovery position Pc using the second conveyor 34b.

[0117] The sheet transfer position Ft is a position for implementing a process in which the first moving machine 40 places the film sheet F1 recovered from the cutting board 22 on the plurality of suction sheets 32d of the multi-fixing fixture 32a and transfers it to the multi-fixing fixture 32a. Preferably, the sheet transfer position Ft is set at a position between the first cutting machine 20 and the second cutting machine 50, where the film sheet F1 is stably placed on the plurality of suction sheets 32d provided on the multi-fixing fixture 32a by the first moving machine 40.

[0118] The product recovery position Pc is a position for performing a process of recovering the product P cut from the film sheet F1 by the second cutter 50 from the multi-fixed fixture 32a by the second mobile machine 70. Preferably, the product recovery position Pc is set at a position between the second cutter 50 and the loader 60, where the product P and the waste S can be stably recovered from the multi-fixed fixture 32a by the second mobile machine 70.

[0119] As described above, when the sheet transfer position Ft and the product recovery position Pc are set, the product recovery position Pc is located at a predetermined distance from the sheet transfer position Ft in the + length direction, and the second cutter 50 is located between the sheet transfer position Ft and the product recovery position Pc.

[0120] Thus, a product forming position Pf can be formed between the sheet transfer position Ft and the product recovery position Pc, and this position corresponds to a position for implementing a process of cutting the film sheet F1 fixed to the multi-fixing fixture 32a by laser using the second cutting machine 50 to separate the film sheet F1 into products P. Preferably, the product forming position Pf is set at a position between the sheet transfer position Ft and the product recovery position Pc so that the film sheet F1 can face the second laser head 52 of the second cutting machine 50 described later in the height direction.

[0121] As described above, when the product forming position Pf is determined, the second stage 34 can reciprocate the support plate 34a and the first stage 32 coupled to the support plate 34a together along the length direction, so that the support plate 34a and the first stage 32 coupled to the support plate 34a pass through the product forming position Pf during the process of being reciprocated along the interval between the sheet transfer position Ft and the product recovery position Pc.

[0122] Fig. 9 and Fig.10 This is a diagram showing a state in which the first moving machine collects the film sheet from the cutting board and transfers it to the multi-fixing fixture.

[0123] Next, the first moving machine 40 is a device that transfers the film sheet F1 from the first cutting machine 20 to the XY stage 30 .

[0124] The structure of the first mobile machine 40 is not particularly limited. Figure 2 As shown, the first moving machine 40 may include a holding machine 42, a transfer machine 44, and the like.

[0125] The holding device 42 can hold the film F1. Figure 4As shown, the holding device 42 may include: a vacuum pump, which is arranged at a preset interval on the lower surface to provide negative pressure; and a plurality of adsorption plates 42a, which are respectively connected to other vacuum components (not shown). When negative pressure is provided from the vacuum component, the plurality of adsorption plates 42a can respectively vacuum adsorb the film F1 to hold it, and when the negative pressure from the vacuum component is disconnected, the vacuum adsorption of the film F1 can be stopped to release the holding of the film F1.

[0126] like Fig. 9 As shown, the conveyor 44 can reciprocate the holding machine 42 along the length direction between the preset sheet recovery position Fc and the sheet transfer position Ft, or reciprocate the holding machine 42 along the height direction in a manner that the distance between the holding machine 42 and the cutting plate 22 or the distance between the holding machine 42 and the multi-fixed clamp 32a can be adjusted.

[0127] The sheet recovery position Fc is a position for implementing a process of recovering the film sheet F1 placed on the cutting board 22 in a state of being separated from the film fabric F0 by the first laser head 24 by the first moving machine 40. Preferably, the sheet recovery position Fc is set at a position of the cutting board 22 where the film sheet F1 placed on the cutting board 22 can be stably recovered.

[0128] Furthermore, preferably, when the gripper 42 needs to be transferred in the length direction, the transfer machine 44 transfers the gripper 42 in the length direction while raising the gripper 42 in the + height direction to a preset reference height in such a manner that the setting height of the gripper 42 is higher than the setting height of the cutting board 22, the multi-fixing fixture 32a, etc. by a predetermined margin. Thus, in the process of the transfer machine 44 reciprocatingly transferring the gripper 42 in the length direction between the sheet recovery position Fc and the sheet transfer position Ft, the gripper 42 can be prevented from colliding with the cutting board 22, the multi-fixing fixture 32a, etc.

[0129] like Figure 4 and Fig. 9 As shown, when the film sheet F1 is formed by cutting the film fabric F0 by the first cutting machine 20, the conveyor 44 raises the holding machine 42 waiting in the sheet transfer position Ft to the reference height in the + height direction, and then transfers it to the sheet recovery position Fc in the - length direction. After that, when the holding machine 42 reaches the sheet recovery position Fc, the conveyor 44 can lower the holding machine 42 in the - height direction to a height that allows the plurality of suction plates 42a to vacuum-absorb the film sheet F1 placed on the cutting plate 22. Therefore, the plurality of suction plates 42a can vacuum-absorb and hold the film sheet F1, thereby recovering it from the cutting plate 22.

[0130] And, if Fig.10As shown, when the film sheet F1 is recovered from the cutting plate 22 by the plurality of suction plates 42a, the transfer machine 44 raises the gripper 42 in the + height direction to the reference height and then transfers it to the sheet transfer position Ft in the + length direction. After that, when the gripper 42 reaches the sheet transfer position Ft, the transfer machine 44 can lower the gripper 42 in the - height direction until the film sheet F1 is placed at the height of the plurality of suction plates 32d of the multi-fixed fixture 32a waiting in the sheet transfer position Ft. Therefore, the plurality of suction plates 42a release the grip of the film sheet F1 and place it on the plurality of suction plates 32d, thereby transferring the film sheet F1 to the multi-fixed fixture 32a, and the transfer machine 44 raises the gripper 42 in the + height direction again to the reference height and then is in a waiting state.

[0131] Through the above process, the first moving machine 40 can transfer the film sheet F1 to the multi-fixing jig 32a by placing it on the plurality of suction sheets 32d of the multi-fixing jig 32a waiting in the sheet transfer position Ft after collecting the film sheet F1 from the cutting board 22 in the sheet collection position Fc. As described above, when the film sheet F1 is transferred to the multi-fixing jig 32a by the first moving machine 40, the multi-fixing jig 32a vacuum-adsorbs the film sheet F1 through the suction holes 32l of the plurality of suction sheets 32d and fixes it in a state of being placed on the plurality of suction sheets 32d.

[0132] Figures 11 to 13 A top view of a multi-fixing fixture for explaining a method of adjusting the number and position of a plurality of adsorption sheets according to processing conditions. Fig.14 This is a diagram showing a state where a multi-fixing jig moves a film sheet to a product forming position.

[0133] and, Fig.15 A diagram for explaining a method of providing a multi-fixing fixture and a second cutting machine when forming two rows of products from a film sheet, Fig.16 This is a diagram for explaining a method of providing multiple fixing jigs and a second cutting machine when forming a plurality of products in one row from a film sheet.

[0134] and, Figures 17 to 19 FIG. 1 is a diagram for explaining a method of determining a predetermined cutting line of a film sheet. Fig. 20 A diagram showing a state in which the second cutting machine releases a laser beam toward the film sheet, Fig.21 This is a diagram showing a state where multiple fixing jigs are transferring a film sheet along a predetermined cutting line.

[0135] and, Fig. 22 A diagram showing the state of products and wastes formed by cutting a film sheet. Fig.23 A diagram showing a state in which a multi-fixture fixture moves products and waste materials to a product transfer position.

[0136] Next, the second cutting machine 50 is a device for laser cutting the film sheet F1 arriving at the product forming position Pf to separate the film sheet F1 into products P having a predetermined shape.

[0137] The structure of the second cutting machine 50 is not particularly limited. Figure 2 As shown, the second cutting machine 50 may include a laser oscillator (not shown), a second laser head 52, a second head driver 54, and the like.

[0138] The laser oscillator generates and oscillates a laser beam LB for cutting the film sheet F1.

[0139] The second laser head 52 can irradiate the laser beam LB transmitted from the laser oscillator to the film sheet F1 that has arrived at the product forming position Pf in a state of being fixed to the multi-fixing jig 32a.

[0140] Preferably, the second laser head 52 is composed of a laser scanner that changes the path of the laser beam LB into at least one of the longitudinal direction and the width direction, but the present invention is not limited thereto. That is, the second laser head 52 may also be composed of a laser nozzle.

[0141] Furthermore, a reflection mirror or other optical components (not shown) may be provided between the laser oscillator and the second laser head 52 to transmit the laser beam LB oscillated from the laser oscillator to the second laser head 52 .

[0142] The second head driver 54 crosses the film sheet F1 fixed to the multi-fixed fixture 32a that has arrived at the product forming position Pf in the width direction, and can move the second laser head 52 in the width direction. For example, the second head driver 54 may have a second slide 54a that moves in the width direction by a drive motor or other drive components, and the second laser head 52 can move in the width direction along the second slide 54a and can be coupled to the second slide 54a so as to face the film sheet F1 that has arrived at the product forming position Pf in a state fixed to the multi-fixed fixture 32a.

[0143] On the other hand, preferably, the second cutting machine 50 can simultaneously cut the film sheet F1 to form a plurality of products P. To this end, the film processing system 1 may include a plurality of second cutting machines 50 arranged between the sheet transfer position Ft and the product recovery position Pc at a preset interval. In addition, the plurality of second cutting machines 50 may respectively include a plurality of second laser heads 52, which can individually irradiate the laser beam LB to the film sheet F1 reaching the product forming position Pf in a state where the plurality of fixing fixtures 32a are reached, and correspondingly, the second head drivers 54 respectively arranged in the plurality of second cutting machines 50 may include a plurality of second sliding parts 54a, which are combined with one of the plurality of second laser heads 52, and can individually reciprocate at least one of the second laser heads 52 in the width direction.

[0144] Hereinafter, a method of cutting the film sheet F1 into products P will be described by taking an example in which a pair of second cutters 50 are arranged at a predetermined interval along the longitudinal direction.

[0145] First, the number and positions of the plurality of suction sheets 32d are adjusted according to processing conditions such as the size and shape of the film sheet F1 and the size and shape of the product P.

[0146] like Fig.11 As shown, the number and position of the plurality of adsorption sheets 32d can be adjusted according to the size and shape of the film sheet F1, so that the entire area of ​​the film sheet F1 can be stably supported by the plurality of adsorption sheets 32d. That is, the number and position of the plurality of adsorption sheets 32d are adjusted so that the entire area of ​​the film sheet F1 is uniformly supported by the plurality of adsorption sheets 32d, so as to prevent the generation of a large-scale non-supported area in the entire area of ​​the film sheet F1 that is not supported by the plurality of adsorption sheets 32d. Thus, the sagging phenomenon of the film sheet F1 caused by the load of the film sheet F1 due to the generation of the non-supported area in a large range of the film sheet F1 can be prevented.

[0147] However, in order to fix the film sheet F1 to the multi-fixing fixture 32a, when the suction sheet 32d is connected to all the multiple vacuum holes 32f located in the area facing the film sheet F1, it is inevitable that the laser beam LB that cuts the film sheet F1 and passes through it will be incident on a part of the suction sheet 32d when the film sheet F1 is laser cut, depending on the processing conditions including at least one of the size and shape of the film sheet F1 and the size and shape of the product P. In this regard, if Fig.12 As shown, preferably, when the film sheet F1 is laser cut, the suction sheet 32d expected to be incident with the laser beam LB passing through the film sheet F1 is selectively separated from the vacuum hole 32f. That is, among the plurality of suction sheets 32d, a specific suction sheet 32d located at a position overlapping with a cutting planned line E of the film sheet F1 described later in the height direction is selectively separated from the multi-fixing jig 32a. Thus, when the film sheet F1 is cut to form the product P, the suction sheet 32d can be prevented from being damaged by the laser beam LB passing through the film sheet F1.

[0148] And, if Fig.13As shown, preferably, the number and positions of the plurality of suction sheets 32d should be adjusted so that when the film sheet F1 is fixed to the multi-fixing jig 32a, no unused plurality of suction sheets 32d that cannot be used to fix the film sheet F1 due to the absence of the film sheet F1 are generated among the plurality of suction sheets 32d. That is, the number and positions of the plurality of suction sheets 32d should be adjusted so that as the size of the film sheet F1 becomes smaller, the area where the plurality of suction sheets 32d are provided gradually decreases, and as the size of the film sheet F1 becomes larger, the area of ​​the area where the plurality of suction sheets 32d are provided gradually increases. Thus, in the process of transferring the film sheet F1 to the multi-fixing jig 32a or collecting the product P and the waste S from the multi-fixing jig 32a, it is possible to prevent the film sheet F1, the product P, the waste S, etc. from colliding with the unused plurality of suction sheets 32d.

[0149] As described above, preferably, the setting operation of the plurality of suction sheets 32d for adjusting the setting number and setting positions of the plurality of suction sheets 32d is performed while the multi-fixing jig 32a is in a waiting state at the sheet transfer position Ft, but it is not limited thereto.

[0150] Afterwards, if Fig. 9 and Fig.10 As shown, the film sheet F1 is collected from the first cutting machine 20 by the first moving machine 40 and placed on a plurality of suction sheets 32d to be transferred to the multi-fixing jig 32a waiting at the sheet transfer position Ft.

[0151] Then, the film sheet F1 is vacuum-adsorbed by the adsorption holes 321 of the plurality of adsorption sheets 32d and fixed to the multi-fixing jig 32a in a state where it is placed on the plurality of adsorption sheets 32d. In this case, the plurality of vacuum holes 32f not coupled to the adsorption sheets 32d are separated from the film sheet F1 in a state where they are located at a position lower than the film sheet F1 by a reference distance L2, and therefore do not substantially contribute to the vacuum adsorption of the film sheet F1.

[0152] Afterwards, if Fig.14 As shown, the support plate 34a and the first stage 32 coupled to the support plate 34a are transferred to the product forming position Pf by the second transfer machine 34b, whereby the film sheet F1 is set at the product forming position Pf in a state fixed to the multi-fixing jig 32a.

[0153] Preferably, when such a film sheet F1 is disposed at the product forming position Pf, the film sheet F1 is disposed in such a manner that the center point of the film sheet F1 is located at the product forming position Pf.

[0154] However, the film processing system 1 includes a pair of second cutting machines 50. According to processing conditions such as the size and shape of the film sheet F1 and the size and shape of the product P, the pair of second cutting machines 50 are driven together to simultaneously cut the film sheet F1 into two rows of products P, or only one of the pair of second cutting machines 50 is selectively driven to cut the film sheet F1 into one row of products P.

[0155] In this regard, Fig.15 As shown, preferably, when two rows of products P are simultaneously cut from the film sheet F1, the middle position between the plurality of second cutters 50 is determined as the product forming position Pf. Fig.16 As shown, preferably, when only one row of products P is formed by cutting the film sheet F1, the setting position of the plurality of second laser heads 52 of one second cutting machine 50 actually used for cutting the film sheet F1 is designated as the product forming position Pf.

[0156] Thereafter, a planned cutting line E is determined as a virtual path for laser cutting the film sheet F1 along the contour of the product P cut from the film sheet F1.

[0157] A plurality of predetermined cutting lines E are defined on the film sheet F1 as many as the number of the plurality of products P cut out from the film sheet F1. Preferably, the plurality of products P cut out from the film sheet F1 have the same shape. In this case, Figures 17 to 19 As shown, a plurality of planned cutting lines E are determined to form a closed loop extending along the same path as the contour line of the product P, and only the coordinate values ​​are determined differently according to the formation positions of the plurality of products P.

[0158] Furthermore, the plurality of predetermined cutting lines E may overlap the protective groove 32e in the height direction so that when the film sheet F1 is cut along the predetermined cutting lines E, the laser beam LB penetrating the film sheet F1 is incident on a position of the protective groove 32e separated from the plurality of adsorption sheets 32d by a preset margin.

[0159] Furthermore, the plurality of planned cutting lines E may be formed at intervals set at predetermined reference intervals across the plurality of products P from the film sheet F1 .

[0160] Furthermore, the plurality of predetermined cutting lines E may have the same number of columns as the number of columns of the plurality of products P formed by cutting the film sheet F1. For example, when two columns of products P are simultaneously cut from the film sheet F1, the plurality of predetermined cutting lines E may be determined as two columns, and when only one column of products P is cut from the film sheet F1, the plurality of predetermined cutting lines E may be determined as one column.

[0161] And, if Fig.17As shown, when a plurality of products P having a greater number of rows than the number of the second laser heads 52 provided in the second cutting machine 50 is cut from the film sheet F1, a plurality of planned cutting lines E can be determined in such a manner that the film sheet F1 is cut stepwise to form a plurality of products P having the same number of rows as the number of the second laser heads 52. In particular, preferably, the total number of rows of the plurality of planned cutting lines E is an integral multiple of the number of the second laser heads 52 provided in the second cutting machine 50, but the present invention is not limited thereto.

[0162] Afterwards, the second head drivers 54 of the multiple second cutting machines 50 are used to adjust the setting intervals and setting positions of the multiple second laser heads 52 according to the set intervals, set positions and other setting conditions of the multiple predetermined cutting lines E, so that the multiple second laser heads 52 irradiate the laser beam LB toward the film sheet F1 along one of the multiple predetermined cutting lines E respectively.

[0163] For example, Fig.15 As shown, when a plurality of predetermined cutting lines E form two rows, the setting intervals and setting positions of the plurality of second laser heads can be adjusted in such a way that all the second laser heads 52 of a pair of second cutting machines 50 are respectively facing the film sheet F1 and irradiate the laser beam LB toward the film sheet F1 along one of the plurality of predetermined cutting lines E.

[0164] For example, Fig.16 As shown, when a plurality of predetermined cutting lines E form a row, the setting interval and setting position of the plurality of second laser heads 52 can be adjusted in such a manner that only one second laser head 52 of a pair of second cutting machines 50 irradiates the laser beam LB to the film sheet F1 along one of the plurality of predetermined cutting lines E while facing the film sheet F1. That is, only the second laser head 52 used for laser cutting of the film sheet F1 is set facing the film sheet F1, and the plurality of second laser heads 52 not used for laser cutting of the film sheet F1 are not set facing the film sheet F1. However, the present invention is not limited to this, and the unused second laser heads 52 may also be set facing the film sheet F1, and only the supply of the laser beam LB to the unused second laser heads 52 is selectively disconnected.

[0165] Afterwards, if Fig. 20 and Fig.21 As shown, the second cutting machine 50 is selectively driven in such a manner that only a plurality of second laser heads 52 actually used for laser cutting of the film sheet F1 release the laser beam LB toward the film sheet F1, and at least one of the first conveyor 32b and the second conveyor 34b of the XY table 30 is used to transfer the multi-fixed fixture 32a and the film sheet F1 fixed on the multi-fixed fixture 32a along the closed loop C1, and the closed loop C1 extends along the same path as the plurality of predetermined cutting lines E.

[0166] Therefore, if Fig. 22As shown, the laser beams LB released respectively from the plurality of second laser heads 52 can irradiate the film sheet F1 along one of the plurality of predetermined cutting lines E and cut the film sheet F1 individually, whereby a plurality of products P of the same number as the plurality of second laser heads 52 actually used for laser cutting and a waste material S remaining as a residue of the film sheet F1 after forming the plurality of products P will be simultaneously separated from the film sheet F1.

[0167] Furthermore, when the film sheet F1 is cut by laser, the plurality of adsorption sheets 32d continue to maintain the vacuum adsorption state using the plurality of adsorption holes 32l, thereby fixing the plurality of products P and waste S cut from the film sheet F1 to the plurality of fixing fixtures 32a. At the same time, the plurality of suction holes 32g can suck in and remove foreign matter generated when the film sheet F1 is cut by laser.

[0168] On the other hand, when the film sheet F1 is cut to form a plurality of products P having a greater number of rows than the number of second laser heads 52 provided in the second cutting machine 50 , the film product P can be cut step by step to form a plurality of products P having the same number of rows as the number of second laser heads 52 .

[0169] Afterwards, if Fig.23 As shown, the second transfer machine 34b is used to transfer the support plate 34a and the first stage 32 combined with the support plate 34a to the product recovery position Pc, and multiple products P and waste materials S are set at the product recovery position Pc in a state of being fixed to the multiple fixing fixtures 32a.

[0170] Fig.24 A diagram showing a schematic structure of a loader.

[0171] Next, the loader 60 is a device for loading a plurality of products P and waste materials S cut from the film sheet F1 by the second cutting machine 50 .

[0172] like Figure 2 As shown, the loader 60 may include a product conveyor 62, a product loading station 64, a waste loading station 66, and the like.

[0173] like Fig.23 As shown, the product conveyor 62 is disposed in the + length direction away from the XY stage 30. For example, the product conveyor 62 may be disposed in the + length direction away from the product recovery position Pc of the XY stage 30 by a predetermined distance.

[0174] And, if Fig.24 As shown, the product conveyor 62 can move along a preset discharge direction and sequentially discharge a plurality of products P transferred by the second moving machine 70 .

[0175] The discharge direction of the plurality of products P is not particularly limited. For example, the discharge direction of the plurality of products P may be the width direction.

[0176] like Fig.24 As shown, the product loading table 64 has a flat plate shape on which a plurality of products P discharged from the product conveyor 62 can be sequentially loaded, and is provided at a predetermined distance in the width direction from the product conveyor 62 .

[0177] like Fig.23 As shown, the waste loading table 66 has a flat plate shape on which the waste S transferred by the second moving machine 70 can be loaded, and is spaced apart from the XY stage 30 in the + length direction. For example, the waste loading table 66 can be spaced apart from the product recovery position Pc of the XY stage 30 in the + length direction by a preset distance, so that the product conveyor 62 is provided between the product recovery position Pc of the XY stage 30 and the waste loading table 66.

[0178] Figure 25 to Figure 27 This is a diagram showing a state in which the second mobile machine collects the film sheet from the multi-fixed fixture and transfers it to the product conveyor. Fig.28 and Fig.29 This is a diagram showing a state in which the second moving machine collects the film sheet from the multi-fixed jig and transfers it to the scrap loading station.

[0179] Next, the second moving machine 70 is a device for supplying a plurality of products P and scraps S from the XY stage 30 to the loader 60 .

[0180] The structure of the second mobile machine 70 is not particularly limited. Figure 2 As shown, the second mobile machine 70 may include a gripping machine 72, a transfer machine 74, and the like.

[0181] like Fig.23 As shown, the holding machine 72 can selectively hold a plurality of products P or waste materials S. For example, the holding machine 72 may include: a vacuum pump, which is arranged on the lower surface at a preset interval to provide negative pressure; and a plurality of adsorption plates 72a, which are respectively connected to other vacuum components (not shown). When negative pressure is provided from the vacuum component, the plurality of adsorption plates 72a can vacuum adsorb the film sheet F1 to hold it, and when the negative pressure from the vacuum component is disconnected, the vacuum adsorption of the film sheet F1 can be stopped to release the holding of the film sheet F1.

[0182] When the plurality of products P are selectively recovered from the multi-fixed jig 32a, the holding machine 72 can selectively hold the plurality of products P by driving only the suction plates 72a disposed at positions corresponding to the positions where the plurality of products P are disposed among the plurality of suction plates 72a. Correspondingly, when the waste S is selectively recovered from the multi-fixed jig 32a, the holding machine 72 can selectively hold the waste S by driving only the suction plates 72a disposed at positions corresponding to the positions where the waste S is disposed among the plurality of suction plates 72a.

[0183] like Fig.23 As shown, the transfer machine 74 reciprocates the gripper 72 along the length direction between the product recovery position Pc and the preset product transfer position Pt or between the product recovery position Pc and the waste transfer position St, or reciprocates the gripper 72 along the height direction in a manner such that the distance between the gripper 72 and the multi-fixed clamp 32a or the distance between the gripper 72 and the product conveyor 62 or the distance between the gripper 72 and the waste loading table 66 can be adjusted.

[0184] The product transfer position Pt is a position for implementing a process in which the second mobile machine 70 places the plurality of products P collected from the multi-fixing fixture 32a on the product conveyor 62 and transfers the plurality of products P to the product conveyor 62. Preferably, the product transfer position Pt is set at a position on the product conveyor 62 where the second mobile machine 70 can be used to stably place the plurality of products P on the product conveyor 62.

[0185] The waste transfer position St is a position for implementing a process in which the second moving machine 70 places the waste S collected from the multi-fixed jig 32a on the waste loading table 66 and loads the waste S on the waste loading table 66. Preferably, the waste transfer position St is set at a position of the waste loading table 66 where the second moving machine 70 can stably place the waste S on the waste loading table 66.

[0186] Furthermore, preferably, when the gripper 72 needs to be transferred in the length direction, the transfer machine 74 transfers the gripper 72 in the length direction while raising the gripper 72 in the + height direction to a preset reference height in such a manner that the setting height of the gripper 72 is higher than the setting height of the multi-fixed fixture 32a, the product conveyor 62, the waste loading platform 66, etc. by a predetermined margin. Thus, in the process of transferring the gripper 72 in the length direction between the product recovery position Pc and the product transfer position Pt or between the product recovery position Pc and the waste transfer position St, the transfer machine 74 can prevent the gripper 72 and the plurality of products P or waste S held by the gripper 72 from colliding with the multi-fixed fixture 32a, the product conveyor 62, the waste loading platform 66, etc.

[0187] like Figure 25 to Figure 27 As shown, after the second mobile machine 70 recovers the plurality of products P from the multi-fixing fixture 32a in the waiting state at the product recovery position Pc, it can place the plurality of products P on the product conveyor 62 at the product transfer position Pt to be transferred to the product conveyor 62. As described above, preferably, when the plurality of products P are recovered from the multi-fixing fixture 32a by the second mobile machine 70, the negative pressure applied to the plurality of suction holes 321 for vacuum adsorbing the plurality of products P is selectively disconnected to release the fixed state of the plurality of products P based on the plurality of suction holes 32l.

[0188] And, if Fig.28 and Fig.29 As shown, after the second moving machine 70 recovers the waste S from the multi-fixing jig 32a in the product recovery position Pc, it is placed on the waste loading stage 66 in the waste transfer position St to be transferred to the waste loading stage 66. As described above, preferably, when the second moving machine 70 is used to recover the waste S from the multi-fixing jig 32a, the negative pressure applied to the plurality of suction holes 32l that vacuum-absorb the waste S is selectively disconnected to release the fixed state of the waste S based on the plurality of suction holes 32l.

[0189] As described above, when the film sheet F1 is transferred or laser cut to form the product P, the film processing system 1 can adjust the shape of the multi-fixing jig 32a used to fix the film sheet F1 to prevent it from moving according to the processing conditions by a simple operation of detaching and attaching the suction sheet 32d of the multi-fixing jig 32a. As a result, the film processing system 1 can perform laser cutting processing on the film sheet F1 according to various processing conditions without replacing the multi-fixing jig 32a itself, and can reduce the cost required for individually preparing a plurality of fixing jigs that are only applicable to specific processing conditions and the time required for the replacement operation of the fixing jigs.

[0190] Generally, the laser head has a structural feature of being long and extending in the direction of gravity. Therefore, when the laser head is transferred in the horizontal direction (length direction, width direction) perpendicular to the direction of gravity, vibrations due to inertia, acceleration, etc. may frequently occur in the laser head. However, the multi-fixing fixture 32a of the present invention can firmly fix the film sheet F1 using a plurality of suction sheets 32d. When the film sheet F1 is transferred in the horizontal direction (length direction, width direction) while the film sheet F1 is fixed to the multi-fixing fixture 32a, almost no vibration occurs in the film sheet F1. In response to this, the film processing system 1 drives the second laser head 52 in a manner of releasing the laser beam LB toward the film sheet F1 while setting the second laser head 52 at the preset processing position. At the same time, the film sheet F1 is transferred along the closed loop C1 using the multi-fixing fixture 32a. The closed loop C1 extends along the same path as the preset cutting predetermined line E, so that the film sheet F1 can be laser cut along the cutting predetermined line. This film processing system 1 can prevent the laser beam LB released from the second laser head 52 from irradiating the film sheet F1 beyond the predetermined cutting line E due to the vibration of the second laser head 52. Therefore, the product P can be precisely laser cut along the predetermined cutting line E to improve the quality of the product P.

[0191] Furthermore, the film processing system 1 is provided with a plurality of second laser heads 52 capable of laser cutting the film sheet F1 individually in the second cutting machine 50. Thus, the film processing system 1 can separate the film sheet F1 into a plurality of products P by transferring the multi-fixing jig 32a and the film sheet F1 fixed to the multi-fixing jig 32a along the closed loop C1 corresponding to the predetermined cutting line E, thereby improving the productivity of the products P.
