Technical Field

[0001] This invention relates to a cutting system, a cutting device, and a cutter unit. Background Technology

[0002] Currently, there are known cutting devices for cutting resin films and other materials that are adhered to workpieces such as substrates.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2010-208311 Summary of the Invention

[0008] The technical problem to be solved by the invention

[0009] However, in recent years, substrates with complex shapes such as curved surfaces have been used. When cutting the film pasted on such substrates, it is difficult to properly cut the film using existing methods that involve continuous cutting with a cutting roller or cutting the film by moving the cutter in a straight line.

[0010] Furthermore, when cutting a film that extends from the edge of a substrate and is attached to a substrate with a complex shape, it is not possible to cut the film by applying tension when one end of the film becomes a free end.

[0011] That is, in the prior art of cutting sheet-like components such as membranes, it is sometimes impossible to cut the sheet-like components properly.

[0012] The objective of this invention is to develop a technique for more properly cutting sheet-like components.

[0018] as well as

[0019] A conveying device that causes relative movement between the cutting device and the object to be cut.

[0031] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0032] [First Implementation Method]

[0033] [structure]

[0034] Figure 1 This is a schematic diagram showing the overall structure of the cutting system 1 involved in the present invention.

[0035] The cutting system 1 is a device for cutting the film 110, and in particular, it has a structure that can easily cut the film 110, which is pasted on a workpiece 100 having a three-dimensional shape (such as a three-dimensional shape), along the workpiece 100 in any orientation.

[0036] Furthermore, in the following description, the component referred to as membrane 110 includes various components that are adhered to the workpiece 100, such as adhesives referred to as film, sealing paper, sheet, mesh, etc.

[0037] like Figure 1 As shown, the cutting system 1 includes a multi-joint robot 10 and a cutting device 20.

[0038] The multi-joint robot 10 (conveyor) is composed of, for example, a six-axis vertical multi-joint robot. By installing the cutting device 20, the cutting device 20 is controlled to any position and posture to cut the film 110 pasted on the workpiece 100.

[0039] The cutting device 20 has a rotating blade 21 that is rotated by an electric motor, which clamps the film 110 while cutting it.

[0040] The cutting device 20 is structured such that the rotating blade 21 is covered by the cutter unit 20B (described later), and a portion of the cutter unit 20B is open, with a portion of the rotating blade 21 protruding from the opening. Furthermore, when cutting the membrane 110, the multi-joint robot 10, on which the cutting device 20 is mounted, moves while changing the posture of the cutting device 20. Thus, the membrane 110 can be clamped into the opening of the cutter unit 20B while being cut by the rotating blade 21.

[0041] Figure 2 This is a schematic diagram (exploded view) showing a specific structural example of the cutting device 20.

[0042] like Figure 2 As shown, in the cutting system 1, the main body 20A and the cutter unit 20B of the cutting device 20 are connected by the connecting part 20C, and the main body 20A and the cutter unit 20B have a detachable structure.

[0043] The main body 20A houses a motor 30 that rotates the rotary cutter 21, and the rotation shaft 30a of the motor 30 protrudes from the end face of the main body 20A. A gear 30b is provided on the rotation shaft 30a of the motor 30, which meshes with a gear 21b provided on the rotation shaft 21a of the rotary cutter 21.

[0044] The cutter unit 20B includes a rotating blade 21, a housing 22, and a guide 23.

[0045] The rotating blade 21 cuts the object to be cut (in this case, the membrane 110) by rotating around the rotating shaft 21a. A gear 21b is provided on the rotating shaft 21a of the rotating blade 21, and the gear 21b meshes with a gear 30b provided on the rotating shaft 30a of the motor 30, thereby transmitting the driving force of the motor 30 to the rotating blade 21.

[0046] In this embodiment, the rotation shaft 21a of the rotating blade 21 is arranged parallel to the rotation shaft 30a of the motor 30, so the rotating blade 21 rotates in a plane parallel to the end face of the main body 20A.

[0047] The housing 22 is configured as a plate-shaped component having an internal space for accommodating the rotating blade 21. In this embodiment, the housing 22 is configured such that at least half the diameter of the rotating blade 21 is accommodated, and a portion of the rotating blade 21 protrudes from the housing 22. Furthermore, a through hole 22a is formed on the back side of the housing 22 for the rotating shaft 21a of the rotating blade 21 to be inserted.

[0048] Figure 3 This is a schematic diagram (exploded view and completed view) showing a structural example of the shell 22.

[0049] like Figure 3 As shown, the housing 22 includes a support member 221, a rear side plate 222, and a front side plate 223.

[0050] The support member 221 serves as a support for the back side plate 222 and the front side plate 223, and has a circular hollow portion 221a in the center with an inner diameter larger than the diameter of the rotating blade 21. Additionally, at one end of the support member 221... Figure 3 The lower end side of the hollow portion 221a has a portion (hereinafter referred to as "open portion 221b") where there are no components surrounding the hollow portion 221a.

[0051] The back side plate-like body 222 is a plate-like member that covers the back side of the support member 221, and is shaped to cover more than 1 / 2 (e.g., 3 / 4) of the diameter of the rotating blade 21. One end of the back side plate-like body 222 ( Figure 3 The lower end side of the support member 221 is disposed at the boundary of the portion where the opening 221b is formed. Figure 3 (The upper end of the open portion 221b in the middle). In addition, on the back side plate-like body 222, when it is mounted on the support member 221, a through hole 222a is formed in the portion opposite to the center of the hollow portion 221a in the support member 221, through which the rotating shaft 21a of the rotating blade 21 is inserted.

[0052] The front side plate 223 is a plate-shaped member that covers the front side of the support member 221. Like the back side plate 222, it is shaped to cover more than 1 / 2 (e.g., 3 / 4) of the diameter of the rotating blade 21. Additionally, one end of the front side plate 223 ( Figure 3 The lower end side of the middle plate 222 is similar to the back plate 222, and is disposed at the boundary of the portion of the support member 221 where the opening 221b is formed. Figure 3 (The upper end of the open part 221b in the middle).

[0053] If a back side plate 222 and a front side plate 223 are provided to sandwich the support member 221, the structure becomes as follows: the back side plate 222 and the front side plate 223 sandwich and cover the upper end of the opening 221b on the support member 221, and are further forward than the opening 221b. Figure 3 The lower end of the support member 221 protrudes from the rear side plate 222 and the front side plate 223. Hereinafter, the portion of the support member 221 that protrudes from the rear side plate 222 and the front side plate 223 will be referred to as the protruding support portion 221c.

[0054] The guide portion 23 is a generally cuboid-shaped component provided in the support member 221 with a protruding support portion 221c, and is configured to become part of the rotating blade 21. Figure 3 The lower part of the groove 23a is a space for rotation. The guide 23 has the following structure: when it is provided on the protruding support 221c, one end side ( Figure 3 The lower end side (of the blade) functions as a protective component covering the outer edge of the rotating blade 21, and the other end side (of the blade) Figure 3 The upper end side) is located at one end of the back side plate 222 and the front side plate 223. Figure 3 A gap is formed between the lower end of the membrane 110 and the rotating blade 21 to allow the membrane 110 to pass through.

[0055] The structure is such that when the guide portion 23 is provided on the protruding support portion 221c of the support member 221, a portion of the rotating blade 21 is exposed in the space (hereinafter referred to as "cutting space S") formed between the back side plate 222 and the front side plate 223 and the guide portion 23.

[0056] In this embodiment, the side of the cutting space S without the support member 221 (i.e., the open side) becomes the opening for inserting the object to be cut (membrane 110). In the housing 22 and the guide portion 23, the portion forming the opening of the cutting space S is provided with an inclined structure such that the opening width increases towards the end of the opening (opening end). This allows for a structure that facilitates the insertion of the object to be cut into the cutting space S. Furthermore, to prevent the operator's body from contacting the rotating blade 21, it is desirable that the shape of the opening is such that the opening width and distance from the opening to the rotating blade 21 do not come into contact with the operator's fingers or similar objects.

[0057] Furthermore, in the cutting space S, the angle between the rotating blade 21 and the guide 23 is set to an acute angle, and the rotation direction of the rotating blade 21 is such that it pulls the object to be cut inward from the opening of the cutting space S. As a result, the object to be cut is clamped by the rotating blade 21 and the guide 23, and even when no tension is applied to the object to be cut, a smooth cut can be performed while applying local tension to the cutting portion.

[0058] Furthermore, after the object to be cut passes through both sides of the rotating blade 21, it passes through both sides of the protruding support portion 221c. However, since the protruding support portion 221c only has the thickness of the support member 221, it does not cause excessive separation of the object to be cut after cutting, and thus can suppress the possibility of reducing the quality of the object to be cut.

[0059] Furthermore, the protruding support portion 221c only needs to have sufficient strength to support the guide portion 23 relative to the housing 22, so it can be made thinner than other parts of the support member 221 within the range of maintaining strength. Additionally, as long as the cut object passes appropriately through both sides of the protruding support portion 221c while ensuring strength to support the guide portion 23 relative to the housing 22, the side of the protruding support portion 221c closest to the rotating blade 21 can be made thinner, forming a shape that becomes thicker further away from the rotating blade 21 (e.g., a tapered shape). Furthermore, the protruding support portion 221c can be constructed using a component with higher strength than other parts of the support member 221, allowing for a thinner wall structure while ensuring strength. For example, the protruding support portion 221c can be made of stainless steel, and the other parts of the support member 221 can be made of aluminum.

[0060] [Disassembly and assembly functions of the cut-off system]

[0061] In the cutting system 1 having the structure described above, the main body 20A and the cutter unit 20B are designed to be easily disassembled and reassembled.

[0062] Figure 4This is a schematic diagram illustrating a structural example in which the main body 20A and the cutter unit 20B are designed to be detachable.

[0063] As a structure for assembling the main body 20A and the cutter unit 20B, for example, it can be configured such that the screw P passes through the connecting portion 20C from the front side plate-like body 223 of the cutter unit 20B and is tightened and fixed to the end face of the main body 20A.

[0064] With this configuration, when the rotating blade 21 needs to be replaced due to blade deterioration, the cutter unit 20B can be removed and replaced without removing the rotating blade 21.

[0065] In addition to the structure of the connecting part 20C that screws the cutter unit 20B onto the main body 20A, the structure can also be configured as follows: a fitting structure is formed between the end face of the main body 20A and the back side plate-like body 222 of the cutter unit 20B, the fitting structure is inserted for assembly during use, and the cutter unit 20B is removed from the main body 20A by releasing the fitting structure when replacing the cutter unit 20B, etc.

[0066] [effect]

[0067] Figure 5 This is a schematic diagram illustrating the function of the cutting system 1 when it cuts the object being cut.

[0068] like Figure 5 As shown, in the cutting system 1, a cutting device 20 can be installed as a tool of the multi-joint robot 10. The cutting device 20 can be arbitrarily controlled by the multi-joint robot 10 to cut the object (film 110).

[0069] exist Figure 5 In the example shown, the film 110, which is pasted on a workpiece 100 made of a substrate (such as a glass substrate) with a curved three-dimensional shape, is cut along the periphery of the workpiece 100.

[0070] When the cutting system 1 cuts the membrane 110, the workpiece 100 to which the membrane 110 is attached is held in a space that is the range of motion of the multi-joint robot 10 by adsorption.

[0071] At this time, the peripheral portion of the membrane 110 extending from the workpiece 100 becomes a state where one end is a free end and no tension is applied.

[0072] For the membrane 110 in this state, the multi-joint robot 10 rotates the motor 30 to move the cutting device 20, so that the membrane 110 comes into contact with the rotating blade 21 from the opening.

[0073] At this point, the opening width of the opening increases towards the end, thus making it easier to introduce the membrane 110.

[0074] Thus, through the pulling action based on the rotation of the rotating blade 21, the membrane 110 is pulled into the cutting space S, and since the angle between the rotating blade 21 and the guide portion 23 is an acute angle, a local tension (the tension generated by the membrane 110 resisting the pulling into the groove portion 23a) is applied, and the membrane 110 is smoothly cut.

[0075] Furthermore, when the multi-joint robot 10 moves the cutting device 20 along the cutting direction of the membrane 110, the cut membrane 110 passes through both sides of the rotating blade 21 and both sides of the protruding support portion 221c and moves towards the rear of the cutting device 20. Figure 5 Move in the direction of the hollow arrow.

[0076] At this time, since the protruding support portion 221c has only the thickness of the support member 221, it will not cause excessive separation of the cut membrane 110, and the possibility of reducing the quality of the membrane 110 can be suppressed.

[0077] Furthermore, the multi-joint robot 10 is capable of cutting at any position and in any posture within its range of motion, so even if the workpiece 100 has a complex shape, it can properly cut the membrane 110 along the periphery of the workpiece 100.

[0078] As described above, the cutting system 1 of this embodiment has a cutter unit 20B having a cutting space S mounted on a multi-joint robot 10. The multi-joint robot 10 controls the cutter unit 20B in any position and posture, and cuts off the unwanted part of the film 110 pasted on the workpiece 100 by means of a rotating blade 21 that is partially exposed in the cutting space S.

[0079] In addition, the opening width of the cutting space S is enlarged, and the angle between the rotating blade 21 and the component constituting the cutting space S (guide 23) is set to an acute angle. The rotation direction of the rotating blade 21 is the direction in which the object to be cut is pulled inward from the opening of the cutting space S.

[0080] Therefore, the membrane 110 can be easily guided into the cutting space S, and the membrane 110 can be clamped by the rotating blade 21 and the guide 23. Even when no tension is applied to the membrane 110, a smooth cutting can be performed while applying local tension to the cutting portion.

[0081] Therefore, according to the cutting system 1, sheet-like components can be cut more appropriately.

[0082] Furthermore, since the rotating blade 21 is housed within the housing 22 and the guide portion 23, and only a portion of it is exposed in the cutting space S, it is possible to prevent the operator's body (fingers, etc.) from coming into contact with the rotating blade 21.

[0083] Furthermore, since the membrane 110, which has been cut and passed through both sides of the rotating blade 21, passes through both sides of the protruding support portion 221c, which has only the thickness of the support member 221, there is no excessive separation of the cut membrane 110, and the possibility of reducing the quality of the cut membrane 110 can be suppressed.

[0084] Furthermore, in the cutting system 1, a structure is designed to minimize interference between the cutting device 20 and the workpiece 100. That is, the main body 20A of the cutting device 20 is positioned relative to the cutting space S on the side opposite to the guide portion 23 (for example, in...). Figure 4 The film 110 is offset from the upper side (in the middle). Therefore, according to the cutting system 1, the film 110 can be cut at a position close to the end edge of the workpiece 100.

[0085] Furthermore, since the rotation surface of the rotating blade 21 is parallel to the end face of the main body 20A, when the main body 20A is mounted as a tool of the articulated robot 10, the movement in the rotational direction of the articulated robot 10 can be increased compared to the direction of extension and retraction of the arm of the articulated robot 10, thus increasing the degree of freedom of the articulated robot 10 in controlling the position and posture of the cutting device 20.

[0086] Furthermore, according to the cutting system 1, in a workpiece 100 such as a substrate with film 110 pasted on both sides, when cutting the end of film 110 pasted on one side, the film 110 that is the object to be cut from the opening of the cutting space S can be reliably guided into the interior only from the film 110 pasted on the adjacent sides (surface and back side), and the film 110 can be cut properly.

[0087] [Variation Example 1]

[0088] In the above embodiment, the following structure is described: the cutter unit 20B of the cutting device 20 includes a protruding support portion 221c and a guide portion 23, and the guide portion 23 provided in the protruding support portion 221c covers a portion of the rotating blade 21 protruding from the housing 22. Figure 3 (The lower part of the middle).

[0089] In contrast, the cutter unit 20B does not have a protruding support portion 221c and guide portion 23, but is combined with a cutting table having a slot into which a rotating blade 21 protruding from the housing 22 can be inserted and moved, thereby obtaining a cutting system 1 that can achieve bidirectional cutting.

[0090] Figure 6This is a schematic diagram illustrating a structural example of a cutting system 1 capable of bidirectional cutting.

[0091] exist Figure 6 In the structural example shown, the cutting system 1 includes a conveying device 10B, a cutting device 20, and a cutting table D.

[0092] The cutter unit 20B of the cutting device 20 differs from the cutter unit 20B of the first embodiment in that it does not have the protruding support portion 221c and guide portion 23 as described above, and the rotating blade 21 protrudes from the housing 22.

[0093] The conveying device 10B can be, for example, composed of a cylinder with direct motion. Furthermore, a cutting device 20 is mounted on the conveying device 10B, and the conveying device 10B moves the cutting device 20 bidirectionally via direct motion. However, the cutting device 20 can also be moved directly by a multi-joint robot 10.

[0094] A groove is formed on the cutting table D for the rotary blade 21 to be inserted. The conveying device 10B moves the cutting device 20 so that the rotary blade 21 moves in the groove of the cutting table D.

[0095] Thus, a structure suitable for continuously cutting the membrane 110 along a straight line in the same direction, such as when the membrane 110 drawn from the roll is continuously cut.

[0096] Furthermore, with this structure, it is possible to cut the membrane 110 while pressing it against the cutting table D and applying tension.

[0097] Furthermore, in this structure, the cutter unit 20B can also be configured to be detachable from the main body 20A, thereby making it easy to replace the rotating blade 21.

[0098] [Variation Example 2]

[0099] In the above embodiment, a structural example of a cutting device 20 in which the rotation axis of the motor 30 is parallel to the rotation axis of the rotating blade 21 has been described, but it is not limited thereto.

[0100] For example, the structure can also be configured as follows: the rotational force of the rotating shaft of the motor 30 is transmitted to the rotating blade 21 by bending 90 degrees through a gear (bevel gear, etc.), and the rotating blade 21 rotates in a plane perpendicular to the end face of the main body 20A.

[0101] In this case, the direction of movement of the cutting device 20 during cutting is different from that in the above embodiment. However, similar to the above embodiment, the membrane 110 can be easily guided into the cutting space S, and the membrane 110 is clamped by the rotating blade 21 and the guide portion 23. Even when no tension is applied to the membrane 110, a smooth cutting can be performed while applying local tension to the cutting portion.

[0102] [Variation Example 3]

[0103] In the above embodiment, the example given is that the protruding support portion 221c in the cutter unit 20B is positioned directly behind the rotating blade 21 (directly downstream and behind the rotating blade 21 in the direction of movement of the membrane 110), but this is not a limitation. That is, the protruding support portion 221c in the cutter unit 20B may also be positioned at a distance from the rotating blade 21.

[0104] Figure 7 This is a schematic diagram showing a modified example of the cutter unit 20B.

[0105] like Figure 7 As shown, the cutter unit 20B in this modified example is relative to Figure 3 The cutter unit 20B shown has protruding support portions 221c arranged at intervals (e.g., a few centimeters) directly behind the rotating blade 21. Between the rear of the rotating blade 21 and the protruding support portions 221c forms a space without any components (hereinafter referred to as the "membrane flow space"). The membrane 110, immediately after being cut by the rotating blade 21, moves within this membrane flow space.

[0106] Therefore, the membrane 110, which has just been cut by the rotating blade 21, moves within the membrane flow space without being caught by components of thickness, and during the stage when it moves a fixed distance away from the cut position of the membrane 110 based on the rotating blade 21, it passes through both sides of the protruding support portion 221c.

[0107] Therefore, since the membrane 110 is sandwiched with a component of thickness after being cut, it is possible to prevent the membrane 110 from cracking at a position earlier than the cutting position of the rotating blade 21.

[0108] Furthermore, in the cutting system 1, the main body 20A of the cutting device 20 is positioned relative to the cutting space S on the side opposite to the guide portion 23 (for example, in...). Figure 4 The middle section is offset from the top side.

[0109] Therefore, in the Figure 7When the cutter unit 20B shown is installed on the main body 20A, it can cut the membrane 110 in any direction relative to the workpiece 100 (the direction in which the main body 20A is located on the side of the workpiece 100 and the direction in which the main body 20A is located on the side opposite to the workpiece 100).

[0110] [Variation Example 4]

[0111] In the above embodiment, the example given is that the protruding support portion 221c on the cutter unit 20B is located directly behind the rotating blade 21 (directly behind the downstream of the rotating blade 21 in the direction of movement of the membrane 110), but it is not limited to this. That is, as in the example shown in Modified Example 3, it is also possible to provide a membrane flow space without any components directly behind the rotating blade 21, and to bend the rear end of the protruding support portion 221c toward the side opposite to the main body 20A.

[0112] Figure 8 This is a schematic diagram showing a modified example of the cutter unit 20B.

[0113] like Figure 8 As shown, the cutter unit 20B in this modified example is relative to Figure 7 The cutter unit 20B shown has a support member 221 with a protruding support portion 221c arranged at a predetermined distance (e.g., a few centimeters or so) from directly behind the rotating blade 21. The rear end (the downstream end in the direction of movement of the membrane 110) bends toward the side opposite to the main body 20A (bending along a fold line in the vertical direction).

[0114] That is, the downstream side of the rotating blade 21 becomes a membrane flow space without any components, the rear end of the membrane flow space is open, and at the front end of the curved support member 221, the protruding support portion 221c is connected to the lower end (the portion where the guide portion 23 is provided).

[0115] Therefore, after the film 110 adhered to the workpiece 100 is cut by the rotating blade 21, it moves within the film flow space and is discharged from the open portion at the rear end. Thus, after the film 110 adhered to the workpiece 100 is cut by the rotating blade 21, it will not come into contact with the component.

[0116] In addition, as the cutting is carried out, the cut end of the membrane 110, which is cut by the rotating blade 21, moves while avoiding the rear end of the curved support member 221.

[0117] Therefore, it can prevent dust from being generated or the quality of the product from being reduced due to the cut membrane 110 coming into contact with the component.

[0118] Furthermore, the present invention can be appropriately modified or improved within the scope of achieving the effects of the present invention, and is not limited to the above-described embodiments.

[0119] For example, in addition to moving the cutting device 20 to cut the object to be cut (such as the membrane 110), the conveying device such as the multi-joint robot 10 can also move the object to be cut relative to the cutting device 20 or move the object to be cut and the cutting device 20 together, and move the object to be cut and the cutting device 20 relative to each other in various ways to cut the object to be cut.

[0120] Alternatively, it can be configured as a structure that appropriately combines the structures of the above-described embodiments and variations.

[0121] For example, the cutter unit 20B of Modified Example 1, which can cut in both directions, can be configured as in Modified Example 2, such that the rotational force of the rotating shaft of the motor 30 is bent by 90 degrees and transmitted to the rotating blade 21.

[0122] As described above, the cutting system 1 in this embodiment includes a multi-joint robot 10 and a cutting device 20, the cutting device 20 including a main body 20A and a cutter unit 20B.

[0123] The main body 20A has an electric motor 30 that rotates the rotating blade 21.

[0124] The cutter unit 20B has a housing 22 that houses a portion of the rotating blade 21 and a guide portion 23 connected to the housing 22 and housing another portion of the rotating blade 21. There is a cutting space S between the housing 22 and the guide portion 23 for guiding the object to be cut (film 110).

[0125] The multi-joint robot 10 causes the cutting device 20 and the object to be cut to move relative to each other.

[0126] A portion of the rotating blade 21 is exposed within the cutting space S, and the cutter unit 20B in the cutting device 20 is detachable from the main body 20A.

[0127] Therefore, by introducing the membrane 110 into the cutting space S, the membrane 110 is clamped by the rotating blade 21 and the guide 23, and even when no tension is applied to the membrane 110, a smooth cutting can be performed while applying local tension to the cutting portion.

[0128] Therefore, according to the cutting system 1, sheet-like components can be cut more appropriately.

[0129] The closer the opening of the cutting space S in the cutter unit 20B is to the opening end, the wider the opening becomes.

[0130] Therefore, the object to be cut can be easily imported into the cutting space S.

[0131] The portion of the cutter unit 20B opposite to the opening of the cutting space S (protruding support portion 221c) is made thinner than the other portions.

[0132] Therefore, it will not cause excessive separation of the cut object after cutting, and can suppress the possibility of reducing the quality of the cut object after cutting.

[0133] The portion of the cutter unit 20B opposite to the opening of the cutting space S (protruding support portion 221c) has a structure that becomes thicker the further away from the cutting space S.

[0134] Therefore, the supporting force of the connecting housing 22 and the guide 23 can be ensured, and the effect of excessive separation of the cut object after cutting can be prevented, thus suppressing the possibility of reducing the quality of the cut object after cutting.

[0135] The portion of the cutter unit 20B opposite to the opening of the cutting space S (protruding support portion 221c) is spaced apart from the rotating blade 21, forming a space (film flow space) between it and the rotating blade 21 where no part exists.

[0136] Thus, the membrane 110, which has just been cut by the rotating blade 21, moves within the membrane flow space without being caught by components of thickness, and during the stage when it moves a fixed distance away from the cut position of the membrane 110 based on the rotating blade 21, it passes through both sides of the protruding support portion 221c.

[0137] Therefore, by clamping a component with thickness between the freshly cut membrane 110 and the component, it is possible to prevent the membrane 110 from cracking at a position earlier than the cutting position of the rotating blade 21.

[0138] The portion of the cutter unit 20B opposite to the opening of the cutting space S (protruding support portion 221c) has a space (film flow space) where no part exists in the portion adjacent to the rotating blade 21, and the end is bent along a zigzag line that intersects the relative movement direction of the cutter unit 20B and the membrane 110.

[0139] Therefore, the film 110 adhered to the workpiece 100 will not come into contact with the part after being cut by the rotating blade 21.

[0140] In addition, as the cutting is carried out, the cut end of the membrane 110, which is cut by the rotating blade 21, moves while avoiding the rear end of the curved support member 221.

[0141] Therefore, it can prevent dust from being generated or the quality of the product from being reduced due to the cut membrane 110 coming into contact with the component.

[0142] The embodiments of the present invention have been described above, but the present invention is not limited to the foregoing embodiments. Furthermore, the effects described in this embodiment are merely examples of the best effects produced by the present invention, and the effects of the present invention are not limited to those described in this embodiment.
