[0002] Conventionally, there is known a laminating device such as a laminator that bonds a film cut according to the position of a substrate or the like to a workpiece on which a substrate or the like is formed.

[0003] When laminating a film on a substrate formed on a workpiece, for example, the film is pre-cut or half-cut into a predetermined shape by a die-cutting roller, and the film is laminated to the accurately positioned workpiece, so that the film of the target shape is laminated to the position where the substrate is formed.

[0004] In addition, a technique for laminating a film on a workpiece is described in Patent Document 1, for example.

[0008] Technical problem to be solved by the invention

[0009] However, when a film cut according to the position of a substrate or the like is bonded to a workpiece, the workpiece needs to be accurately positioned so that the shape of the cut film matches the position of the target region of the substrate or the like and bonded.

[0010] Therefore, a device that can measure the position of the workpiece with high precision and accurately position the workpiece is required, and the film is also required to be cut with a high-precision shape.

[0011] That is, it is difficult to easily adhere a cut sheet member such as a film to a workpiece.

[0018] a workpiece state detection unit configured to detect a deviation state of the workpiece before the sheet component is attached by the attachment unit; and

[0019] a sheet component pre-processing unit, which pre-processes the sheet component supplied by the sheet component supplying unit based on the detection result of the workpiece state detection unit so that the cutting position corresponds to the deviation state of the workpiece,

[0031] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0032] [structure]

[0033] Figure 1 It is a schematic diagram showing the overall structure of the laminator 1 of the present invention.

[0034] The laminator 1 is constructed as an embodiment of the pasting device of the present invention, and performs processing of pasting the upper surface film 200 and the lower surface film 300 that are pre-cut corresponding to the shape of the pasting object (substrate) to the upper surface and the lower surface of the workpiece 100 that is the pasting object (here, the substrate) processed into a predetermined shape. At this time, after the laminator 1 detects the position and posture of the workpiece 100, the upper surface film 200 and the lower surface film 300 are cut in a shape corresponding to the pasting object (substrate) corresponding to the deviation of the position and posture of the workpiece 100. Thus, when the cut upper surface film 200 and the lower surface film 300 are pasted on the workpiece 100, even if the position and posture of the workpiece 100 deviate from the position and posture used as the reference, the upper surface film 200 and the lower surface film 300 of the shape corresponding to the pasting object (substrate) can be pasted corresponding to the position and posture of the workpiece 100 (substrate).

[0035] Therefore, the cut sheet-like members (the upper surface film 200 and the lower surface film 300 ) can be more easily attached to the workpiece 100 .

[0036] In the following description, the member referred to as the upper surface film 200 or the lower surface film 300 includes various members attached to the workpiece 100 , for example, a sheet-like attached object such as a film, a seal, a sheet, a net, etc.

[0037] like Figure 1 As shown, the laminator 1 includes an input section 10, a camera 20, an upper surface film supply section 30, an upper surface film cutting section 40, a lower surface film supply section 50, a lower surface film cutting section 60, an upper side laminating roller 70A, a lower side laminating roller 70B, a discharge section 80 and a control section 90.

[0038] The input part 10 is provided with a conveying roller or a conveying mechanical arm etc. having an actuator for rotating a rotating shaft, and the workpiece 100 which will become the object of laminating the upper surface film 200 and the lower surface film 300 is put into the laminating process. Specifically, the input part 10 is transported between the upper laminating roller 70A and the lower laminating roller 70B to become the object of lamination. In the position directly in front of the upper laminating roller 70A and the lower laminating roller 70B (near the upstream side in the conveying direction of the workpiece 100), the upper surface film stripping component 34 and the lower surface film stripping component 54 described later are provided, and the upper surface film 200 stripped by the upper surface film stripping component 34 and the lower surface film 300 stripped by the lower surface film stripping component 54 are transported between the upper laminating roller 70A and the lower laminating roller 70B in the state of temporarily sticking on the workpiece 100.

[0039] The camera 20 photographs the workpiece 100 to be laminated with the upper film 200 and the lower film 300 at the upstream side of the upper laminating roller 70A and the lower laminating roller 70B in the conveying direction. The image of the workpiece 100 photographed by the camera 20 is used to detect the deviation of the workpiece 100 from the reference position and the deviation from the reference posture.

[0040] The upper surface film supply unit 30 includes a supply roller 30A wound with the upper surface film 200 laminated on the workpiece 100 and a winding roller 30B winding the upper surface film 200 released from the supply roller. The supply roller 30A and the winding roller 30B are provided with an actuator for rotating the rotating shaft. The upper surface film supply unit 30 rotates the rotating shafts of the supply roller 30A and the winding roller 30B at a predetermined speed according to the control of the control unit 90, and supplies the upper surface film 200 to the position directly in front of the upper laminating roller 70A and the lower laminating roller 70B. In the present embodiment, the upper surface film supply unit 30 includes guide rollers 31 to 33, 35, 36 and an upper surface film peeling component 34. The upper surface film 200 fed from the supply roller 30A of the upper surface film supply unit 30 changes its direction in the direction of the position directly in front of the upper laminating roller 70A and the lower laminating roller 70B through the guide roller 31, and reaches the position of the upper surface film peeling component 34 set in the position directly in front of the upper laminating roller 70A after being guided by the guide rollers 32 and 33. Here, the area between the guide rollers 31 and 32 becomes the area where the upper surface film 200 is cut by the upper surface film cutting unit 40, and the upper surface film 200 is cut into a shape corresponding to the workpiece 100 (substrate) while being transported (or stationary). At the position of the guide roller 32, the part (blank part) of the upper surface film 200 that is not laminated on the workpiece 100 changes its direction of travel and is wound onto a blank winding roller not shown in the figure. In addition, the portion of the upper surface film 200 laminated on the workpiece 100 is guided in the direction of the guide roller 33, and the upper surface film 200 folded back at the front end from the guide roller 33 through the front end of the upper surface film peeling part 34 is guided by the guide rollers 35 and 36 and wound on the winding roller 30B.

[0041] In the present embodiment, the upper film peeling member 34 has a wedge shape, and the tip of the wedge formed at an acute angle is disposed toward the upper laminating roller 70A.

[0042] Figure 2 1 is a schematic diagram showing a structural example of the upper film peeling member 34 .

[0043] In addition, Figure 2 2 is a cross-sectional view of the upper film peeling member 34 along the conveying direction.

[0044] like Figure 2 As shown, the front end of the upper surface film stripping component 34 is made into the curved surface of predetermined radius (the cross section along the conveying direction is a curved surface), and the upper surface film 200 is folded back at this front end. In addition, the front end of the upper surface film stripping component 34 is made into the curved surface of the radius of the sharpness of the degree that the upper surface film 200 is not cut off, and the pasting of fluororesin tape, fluororesin coating or DLC (Diamond Like Carbon, diamond-like carbon) coating etc. have been implemented to be used for the processing that reduces friction. When the upper surface film 200 is folded back at the front end of the upper surface film stripping component 34, the part laminated on the workpiece 100 is peeled off from the base material of the upper surface film 200, and is temporarily pasted on the workpiece 100 (substrate) from the upper surface side. At this moment, the upper surface film 200 is cut off with the position corresponding to the deviation of the position and posture of the workpiece 100 that becomes the object of lamination, even when therefore workpiece 100 is not accurately positioned, also can be laminated on the appropriate position upper surface film 200.

[0045] return Figure 1 , the upper surface film cutting section 40 is composed of a cutting device such as a laser cutter that can easily change the cutting direction. In the present embodiment, the upper surface film cutting section 40 cuts (pre-cuts) the upper surface film 200 in accordance with the instructions from the control section 90 and in a manner corresponding to the deviation of the workpiece 100 from the reference position and the deviation from the reference posture photographed by the camera 20. That is, the upper surface film cutting section 40 cuts the upper surface film 200 in a shape corresponding to the workpiece 100 (substrate) in a manner corresponding to the distance of deviation of the workpiece 100 from the reference position and the degree of deviation of the workpiece 100 from the reference posture. In addition, in the present embodiment, the upper surface film cutting section 40 leaves the base material of the upper surface film 200 composed of the adhesive film bonded to the base material, and only cuts (half-cuts) the adhesive film.

[0046] The lower surface film supply unit 50 includes a supply roller 50A wound with the lower surface film 300 laminated on the workpiece 100 and a winding roller 50B winding the lower surface film 300 drawn from the supply roller. The supply roller 50A and the winding roller 50B are provided with an actuator for rotating the rotating shaft. The lower surface film supply unit 50 rotates the rotating shafts of the supply roller 50A and the winding roller 50B at a predetermined speed according to the control of the control unit 90, and supplies the lower surface film 300 to the position directly in front of the upper laminating roller 70A and the lower laminating roller 70B. In the present embodiment, the lower surface film supply unit 50 includes guide rollers 51 to 53, 55, 56 and a lower surface film peeling component 54. The lower surface film 300 sent out from the supply roller 50A of the lower surface film supply unit 50 changes its direction in the direction of the position directly in front of the upper laminating roller 70A and the lower laminating roller 70B through the guide roller 51, and reaches the position of the lower surface film peeling component 54 set in the position directly in front of the lower laminating roller 70B after being guided by the guide rollers 52 and 53. Here, the area between the guide rollers 51 and 52 becomes the area where the lower surface film 300 is cut by the lower surface film cutting unit 60, and the lower surface film 300 is cut into a shape corresponding to the workpiece 100 (substrate) while being transported (or stationary). At the position of the guide roller 52, the part (blank part) of the lower surface film 300 that is not laminated on the workpiece 100 changes its direction of travel and is wound onto a blank winding roller not shown in the figure. In addition, the part of the lower surface film 300 laminated on the workpiece 100 is guided along the direction of the guide roller 53, and the lower surface film 300 folded back at the front end is guided by guide rollers 55, 56 from the guide roller 53 via the front end of the lower surface film stripping component 54, and is wound up by the winding roller 50B. In the present embodiment, the lower surface film stripping component 54 has a wedge shape like the upper surface film stripping component 34, and the front end of the wedge formed into an acute angle is set towards the direction of the lower side laminating roller 70B. The front end of the lower surface film stripping component 54 is made into a curved surface (a cross section along the conveying direction is a curved surface) of a predetermined radius, and the lower surface film 300 is folded back at this front end. In addition, the front end of the lower surface film stripping component 54 is made into a curved surface with a radius of sharpness of the degree that the lower surface film 300 is not cut, and the pasting of fluororesin tape, fluororesin coating or DLC coating, etc. have been implemented for the processing of reducing friction. When the lower surface film 300 is folded back at the front end of the lower surface film stripping member 54, the portion laminated on the workpiece 100 is peeled off from the base material of the lower surface film 300 and temporarily attached to the workpiece 100 (substrate) from the lower surface side. At this time, the lower surface film 300 is cut at a position and orientation corresponding to the deviation of the position and posture of the workpiece 100 to be laminated, so even if the workpiece 100 is not accurately positioned, the lower surface film 300 can be laminated at an appropriate position.

[0047] The lower surface film cutting section 60 is composed of a cutting device such as a laser cutter that can easily change the cutting direction. In the present embodiment, the lower surface film cutting section 60 cuts the lower surface film 300 (pre-cut) correspondingly to each workpiece 100 in a manner corresponding to the deviation of the workpiece 100 from the reference position and the deviation from the reference posture photographed by the camera 20 according to the instruction from the control section 90. That is, the lower surface film cutting section 60 cuts the lower surface film 300 in a shape corresponding to the workpiece 100 (substrate) in a manner corresponding to the distance that the workpiece 100 deviates from the reference position and the degree that the workpiece 100 deviates from the reference posture. In addition, in the present embodiment, the lower surface film cutting section 60 leaves the base material of the lower surface film 300 composed of the adhesive film bonded to the base material, and only cuts (half-cuts) the adhesive film.

[0048] The upper laminating roller 70A is provided with an actuator for rotating the rotating shaft, and the rotation speed is controlled by the control unit 90. The upper laminating roller 70A sandwiches the upper surface film 200, the workpiece 100, and the lower surface film 300 between it and the lower laminating roller 70B, and presses the upper surface film 200 temporarily attached to the upper surface of the workpiece 100 toward the workpiece 100. Thus, the upper surface of the workpiece 100 (substrate) is laminated with the upper surface film 200.

[0049] The lower laminating roller 70B is provided with an actuator for rotating the rotating shaft, and the rotation speed is controlled by the control unit 90. The lower laminating roller 70B sandwiches the upper surface film 200, the workpiece 100, and the lower surface film 300 between it and the upper laminating roller 70A, and presses the lower surface film 300 temporarily attached to the lower surface of the workpiece 100 toward the workpiece 100. Thus, the lower surface of the workpiece 100 (substrate) is laminated by the lower surface film 300.

[0050] The discharge unit 80 includes a conveying roller having an actuator for rotating a rotation axis or a conveying robot arm, etc., and conveys (discharges) the workpiece 100 (substrate) laminated with the upper film 200 and the lower film 300 to hand it over to a subsequent process.

[0051] The control unit 90 is composed of a computing device such as a PLC (Programmable Logic Controller) or a PC (Personal Computer) and a device with a control function equipped with a memory, and controls the overall operation of the laminating machine 1. For example, the control unit 90 moves the workpiece 100 through the input unit 10 or the discharge unit 80, controls the delivery of the upper surface film 200 or the lower surface film 300, controls the rotation of the upper side laminating roller 70A and the lower side laminating roller 70B, or controls the shooting of the camera 20 or the cutting of the upper surface film cutting unit 40 and the lower surface film cutting unit 60.

[0052] [Method of Cutting Upper Surface Film 200 and Lower Surface Film 300]

[0053] Figure 3 It is a schematic diagram showing a method of cutting the upper surface film 200 and the lower surface film 300 .

[0054] exist Figure 3 In the figure, as shown as "(1) a workpiece 100 having a deviation from a reference position and a reference posture", the workpiece 100 is in a state where it deviates by y [mm] from the center in a direction (width direction) intersecting the conveying direction, and deviates (rotates) by θ [degrees] in the surface direction from the posture directly opposite to the conveying direction.

[0055] Here, in the laminator 1 of this embodiment, the workpiece 100 does not need to be strictly positioned, and the camera 20 detects the deviation of the workpiece 100 from the reference position and the deviation from the reference posture before being put into the upper laminating roller 70A and the lower laminating roller 70B.

[0056] That is, based on the image of the workpiece 100 captured by the camera 20 , the control unit 90 detects the deviation y [mm] from the center in the direction intersecting the conveying direction (width direction) and the rotation angle θ [degrees] in the plane direction from the posture facing the conveying direction.

[0057] Moreover, in Figure 3 In the figure, as shown in "(2) Cutting example of the upper surface film 200", the upper surface film 200 is cut by the upper surface film cutting unit 40 in a shape pasted on the workpiece 100 (substrate), that is, it is cut in a shape rotated by θ [degrees] along the surface direction from a posture directly opposite to the conveying direction to a position deviated by y [mm] from the center in the width direction of the upper surface film 200. In addition, except for the portion pasted on the workpiece 100 (substrate), as shown in "(3) Blank example of the upper surface film 200", it is processed in a continuous state and is wound onto a blank winding roller not shown in the figure.

[0058] Likewise, in Figure 3 In the figure, as shown in "(4) Cutting example of the lower surface film 300", the lower surface film 300 is cut by the lower surface film cutting unit 60 in a shape pasted on the workpiece 100 (substrate), that is, it is cut in a shape rotated by θ [degrees] along the surface direction from a posture directly opposite to the conveying direction to a position deviated by y [mm] from the center of the width direction of the lower surface film 300. However, in the lower surface film 300, the position and rotation angle are defined by coordinates that are in a mirror-image relationship with the upper surface film 200. In addition, except for the portion pasted on the workpiece 100 (substrate), as shown in "(5) Blank example of the lower surface film 300", it is processed in a continuous state and is wound onto a blank winding roller not shown in the figure.

[0059] The upper surface film 200 and the lower surface film 300 cut in this way are conveyed to the positions of the upper side laminating roller 70A and the lower side laminating roller 70B while the phases of the workpiece 100 and the conveying direction (x direction) are aligned.

[0060] Then, the laminated portion of the upper film 200 peeled off by the upper film peeling member 34 is temporarily attached to the upper surface of the workpiece 100 , and the laminated portion of the lower film 300 peeled off by the lower film peeling member 54 is temporarily attached to the lower surface of the workpiece 100 .

[0061] With the upper surface film 200 and the lower surface film 300 temporarily attached, the workpiece 100 is conveyed between the upper laminating roller 70A and the lower laminating roller 70B, and is pressed from top to bottom, as shown as “(6) laminated workpiece 100”, thereby forming a workpiece 100 laminated by the upper surface film 200 and the lower surface film 300.

[0062] [Functional Structure of Control Unit 90]

[0063] Next, the functional structure of the control unit 90 will be described.

[0064] Figure 4 It is a block diagram showing a functional structure formed in the control unit 90.

[0065] The control unit 90 executes a program for controlling the laminator 1, thereby forming a workpiece conveying control unit 91, a workpiece status detection unit 92, an upper surface film conveying control unit 93, an upper surface film cutting control unit 94, a lower surface film conveying control unit 95 and a lower surface film cutting control unit 96 as a functional structure.

[0066] The workpiece conveyance control unit 91 controls conveyance of the workpiece 100 to be processed. Specifically, the workpiece conveyance control unit 91 controls the input unit 10, the upper laminating roller 70A, the lower laminating roller 70B, and the discharge unit 80 to convey the workpiece 100 at a predetermined timing and speed.

[0067] The workpiece state detection unit 92 captures an image of the workpiece 100 before lamination by the upper laminating roller 70A and the lower laminating roller 70B. Then, the workpiece state detection unit 92 detects the deviation y [mm] of the position of the workpiece 100 from the center in the direction (width direction) intersecting the conveying direction and the deviation (rotation angle) θ [degrees] of the workpiece 100 in the plane direction from the posture facing the conveying direction.

[0068] The top film conveyance control unit 93 controls an actuator that rotates the rotation axes of the supply roller 30A and the winding roller 30B of the top film supply unit 30 to convey the top film 200 at a predetermined timing and speed.

[0069] The upper surface film cutting control unit 94 cuts the upper surface film 200 at a position and posture corresponding to the deviation of the workpiece 100 from the reference position and reference posture based on the detection result of the workpiece state detection unit 92. Specifically, the upper surface film cutting control unit 94 cuts the upper surface film 200 into a predetermined shape pasted on the upper surface of the workpiece 100 at a position y [mm] away from the reference position (center in the width direction) of the upper surface film 200, in a state rotated by θ [degrees] in the surface direction from a posture directly opposite to the conveying direction.

[0070] The lower film conveyance control unit 95 controls an actuator that rotates the rotation axes of the supply roller 50A and the winding roller 50B of the lower film supply unit 50 to convey the lower film 300 at a predetermined timing and speed.

[0071] The lower surface film cutting control unit 96 cuts off the lower surface film 300 at a position and posture corresponding to the deviation of the workpiece 100 from the reference position and reference posture based on the detection result of the workpiece state detection unit 92. Specifically, the lower surface film cutting control unit 96 cuts off the lower surface film 300 at a position y [mm] away from the reference position (center in the width direction) of the lower surface film 300, in a state rotated by θ [degrees] in the surface direction from a posture directly opposite to the conveying direction, into a predetermined shape pasted on the upper surface of the workpiece 100. In addition, in the lower surface film cutting control unit 96, the cutting position and rotation angle of the lower surface film 300 are defined by coordinates (i.e., left-right inverted coordinates) that are in a mirror-image relationship with the position and rotation angle in the upper surface film cutting control unit 94.

[0072] [action]

[0073] Next, the operation of the laminator 1 will be described.

[0074] Figure 5 1 is a flowchart showing the flow of the laminating process performed by the laminator 1 .

[0075] The laminating process is a process for laminating the upper surface film 200 and the lower surface film 300 on the workpiece 100 by the laminator 1 .

[0076] When the laminating process starts, in step S1 , the control unit 90 conveys (supplies) the workpiece 100 via the input unit 10 to a position in front of the upper laminating roller 70A and the lower laminating roller 70B.

[0077] In step S2 , the control unit 90 uses the camera 20 to image the supplied workpiece 100 .

[0078] In step S3 , the control unit 90 detects the deviation state of the workpiece 100 (ie, the deviation y [mm] from the reference position and the deviation (rotation angle) θ [degrees] from the reference posture) based on the imaged image of the workpiece 100 .

[0079] In step S4, the control unit 90 cuts the upper surface film 200 in accordance with the deviation of the upper surface film cutting unit 40 and the workpiece 100 from the reference position and the deviation from the reference posture. In addition, the control unit 90 cuts (pre-cuts) the lower surface film 300 in accordance with the deviation of the lower surface film cutting unit 60 and the workpiece 100 from the reference position and the deviation from the reference posture.

[0080] In step S5, the control unit 90 conveys the workpiece 100 between the upper laminating roller 70A and the lower laminating roller 70B through the input unit 10, and conveys the upper surface film 200 and the lower surface film 300 in phase with the workpiece 100 through the upper surface film supply unit 30 and the lower surface film supply unit 50. Thus, the upper surface film 200 and the lower surface film 300 that have been cut in advance according to the deviation state of the workpiece 100 (deviation from the reference position and deviation from the reference posture) are put into the lamination process in a configuration suitable for the deviation state of the workpiece 100.

[0081] In step S6 , the control unit 90 rotates the upper laminating roller 70A and the lower laminating roller 70B to laminate the upper surface film 200 and the lower surface film 300 on the upper surface and the lower surface of the workpiece 100 .

[0082] In step S7 , the control unit 90 discharges the workpiece 100 on which the upper surface film 200 and the lower surface film 300 are laminated via the discharge unit 80 , and hands it over to a subsequent process.

[0083] As described above, the laminator 1 of the present embodiment takes an image of the workpiece 100 before lamination processing, and detects the deviation of the workpiece 100 from the reference position and the reference posture. Then, the laminator 1 cuts off (pre-cuts) the upper surface film 200 and the lower surface film 300 correspondingly to the deviation from the reference position and the reference posture detected. Furthermore, the laminator 1 makes the phases of the workpiece 100, the upper surface film 200 and the lower surface film 300 consistent and puts them into the lamination processing. At this time, the upper surface film 200 and the lower surface film 300 that are cut in advance according to the deviation state of the workpiece 100 (deviation from the reference position and deviation from the reference posture) are peeled off from the substrate, and are temporarily pasted on the workpiece 100 with the configuration suitable for the deviation state of the workpiece 100. Thereafter, the workpiece 100 , the pre-cut upper film 200 , and the lower film 300 are pressed by the upper laminating roller 70A and the lower laminating roller 70B, and the upper film 200 and the lower film 300 are laminated on the upper and lower surfaces of the workpiece 100 .

[0084] Therefore, when attaching the film cut according to the shape of the workpiece 100, it is not necessary to accurately position the workpiece 100. In addition, since the film can be cut according to the position and posture of the workpiece 100, it is not necessary to cut the film into an expected shape with high accuracy.

[0085] Therefore, the cut film can be easily attached to the workpiece 100 .

[0086] In particular, when a film consisting of a continuous body is sequentially cut and pasted according to the shape of the continuously supplied workpiece 100, the film cut into a predetermined shape can be easily pasted to the workpiece 100 even when the position and posture of the workpiece 100 are deviated.

[0087] [Modification 1]

[0088] In the above embodiment, the laminator 1 is described as a structure in which the pre-cut upper surface film 200 and the lower surface film 300 are attached to the upper surface and the lower surface of the workpiece 100, but is not limited thereto. That is, the laminator 1 can also be a structure in which the pre-cut film is attached to the surface of one side of the workpiece 100.

[0089] Figure 6 1 is a schematic diagram showing a configuration example of a laminator 1 for attaching a pre-cut film to one surface of a workpiece 100 .

[0090] exist Figure 6 In the structural example of the laminator 1 shown, there are Figure 1 The laminator 1 shown in the figure includes an input unit 10, a camera 20, an upper film supply unit 30, an upper film cutting unit 40, an upper laminating roller 70A, and a control unit 90. Figure 6 In the structural example of the laminator 1 shown in the figure, the input unit 10 for moving the workpiece 100 has Figure 1 The function of the discharge section 80 in the laminator 1 is shown.

[0091] In this structure, Figure 6 The laminator 1 shown in the figure takes an image of the workpiece 100 before the lamination process, and detects the deviation of the workpiece 100 from the reference position and the reference posture. Then, the laminator 1 cuts (pre-cuts) the upper surface film 200 in accordance with the deviation from the reference position and the reference posture detected. Furthermore, the laminator 1 makes the phases of the workpiece 100 and the upper surface film 200 consistent and puts them into the lamination process. At this time, the upper surface film 200 that is cut in advance according to the deviation state of the workpiece 100 (deviation from the reference position and deviation from the reference posture) is temporarily pasted on the workpiece 100 with the configuration suitable for the deviation state of the workpiece 100. Afterwards, the workpiece 100 and the pre-cut upper surface film 200 are pressed by the upper side laminating roller 70A, and the upper surface film 200 is laminated to the upper surface of the workpiece 100.

[0092] Therefore, when the film cut according to the shape of the workpiece 100 is attached to one surface of the workpiece 100, it is not necessary to accurately position the workpiece 100. In addition, since the film can be cut according to the position and posture of the workpiece 100, it is not necessary to cut the film into the desired shape with high precision.

[0093] Therefore, the cut film can be easily attached to the workpiece 100 .

[0094] [Modification 2]

[0095] In the above embodiment, the structure in which the laminator 1 peels off the pre-cut upper surface film 200 and lower surface film 300 from the base material and sticks them to the upper surface and lower surface of the workpiece 100 composed of a substrate composed of metal or glass, etc. is described, but it is not limited to this. That is, the laminator 1 can also pre-cut the adhesive film without the base material and stick it to the upper surface of the sheet-like workpiece 100 to form a sheet-like product in which the upper surface film 200 and the workpiece 100 are integrated.

[0096] Figure 7 1 is a schematic diagram showing a configuration example of a laminator 1 that pre-cuts an adhesive film having no substrate and bonds the pre-cut film to the upper surface of a sheet-like workpiece 100 .

[0097] exist Figure 7 In the structural example of the laminator 1 shown in FIG. Figure 1 The structure of the laminator 1 shown in the figure is similarly provided with an input unit 10, a camera 20, an upper film supply unit 30, an upper film cutting unit 40, an upper laminating roller 70A, a lower laminating roller 70B, and a control unit 90. Figure 7 The upper film supply unit 30 of the laminator 1 shown in the figure does not include the upper film peeling unit 34, and the pre-cut upper film 200 (adhesive film) is attached to the workpiece 100. Figure 7 In the configuration example of the laminator 1 shown in the figure, the winding roller 30B for winding up the sheet-like workpiece 100 has Figure 1 The function of the discharge section 80 in the laminator 1 is shown.

[0098] In this structure, Figure 7The laminator 1 shown in the laminating process, before the laminating process, takes the image of the workpiece 100, detects the deviation of the workpiece 100 from the reference position and the reference posture. Then, the laminator 1 cuts off (pre-cuts) the upper surface film 200 accordingly with the deviation from the reference position and the reference posture detected. And then, the laminator 1 makes the phase of the workpiece 100 and the upper surface film 200 consistent, and puts into the laminating process. At this time, the upper surface film 200 that is cut in advance according to the deviation state of the workpiece 100 (deviation from the reference position and deviation from the reference posture) is temporarily pasted on the workpiece 100 with the configuration suitable for the deviation state of the workpiece 100. Afterwards, the workpiece 100 and the pre-cut upper surface film 200 are pressed by the upper side laminating roller 70A and the lower side laminating roller 70B, and the workpiece 100 is laminated by the upper surface film 200. In the lower surface film 200, temporary pasting and lamination are also carried out in the same manner.

[0099] Therefore, when attaching the film cut according to the shape of the workpiece 100, it is not necessary to accurately position the workpiece 100. In addition, since the film can be cut according to the position and posture of the workpiece 100, it is not necessary to cut the film into an expected shape with high accuracy.

[0100] Therefore, the cut film can be easily attached to the workpiece 100 .

[0101] [Variation 3]

[0102] In the above-mentioned embodiment, the structure of cutting (pre-cutting) the upper surface film 200 and the lower surface film 300 accordingly with the deviation of the workpiece 100 detected from the reference position and the reference posture of the laminating machine 1 before the laminating process is described, but it is not limited to this. That is, it can also be set as follows: the upper surface film 200 and the lower surface film 300 are cut into a specified shape in advance, and when the upper surface film 200 and the lower surface film 300 are pasted on the workpiece 100, the unit including the upper surface film supply unit 30 and the unit including the lower surface film supply unit 50 are moved respectively.

[0103] Figure 8 1 is a schematic diagram showing a configuration example of a laminator 1 that can move the entire unit including the upper surface film supply unit 30 and the entire unit including the lower surface film supply unit 50 relative to the workpiece 100 .

[0104] exist Figure 8 In the structural example of the laminator 1 shown in FIG. Figure 1 The structure of the laminator 1 shown does not include the upper film cutting unit 40 and the lower film cutting unit 60 , but includes a camera 20A for photographing the upper film 200 and a camera 20B for photographing the lower film 300 .

[0105] In addition, Figure 8In the structural example of the laminator 1 shown, there are provided a tension-adjusting feed mechanism 30C for adjusting the tension of the upper surface film 200, a position-adjusting feed mechanism 30D for adjusting the delivery amount (position in the conveying direction) of the upper surface film 200, a tension-adjusting feed mechanism 50C for adjusting the tension of the lower surface film 300, and a position-adjusting feed mechanism 50D for adjusting the delivery amount (position in the conveying direction) of the lower surface film 300. Figure 8 In the structure example of the laminator 1 shown in FIG. 1 , as the conveying path of the upper film 200 and the lower film 300 is connected to the Figure 1 The laminator 1 shown is different in that the guide rollers 32 and 52 are not provided, but guide rollers 37 and 57 are provided just in front of the winding rollers 30B and 50B.

[0106] Moreover, in Figure 8 In the structural example of the laminator 1 shown, the upper surface film supply unit 30, the camera 20A, the feed mechanism 30C for tension adjustment, the feed mechanism 30D for position adjustment, the upper surface film peeling component 34 and the guide rollers 31, 33, 35, 36, 37 constitute the upper surface film unit 200A. The upper surface film unit 200A can be moved in a predetermined direction (y direction and θ direction) by the upper surface film unit moving mechanism 200B that moves the upper surface film unit 200A as a whole. The upper surface film unit moving mechanism 200B moves the upper surface film unit 200A in a predetermined direction, for example, by an electric actuator or a hydraulic actuator.

[0107] Likewise, in Figure 8 In the structural example of the laminator 1 shown, the lower surface film supply unit 50, the camera 20B, the feed mechanism 50C for tension adjustment, the feed mechanism 50D for position adjustment, the lower surface film peeling component 54 and the guide rollers 51, 53, 55, 56, 57 constitute the lower surface film unit 300A. The lower surface film unit 300A can be moved in a predetermined direction (y direction and θ direction) by a lower surface film unit moving mechanism 300B that moves the lower surface film unit 300A as a whole. The lower surface film unit moving mechanism 300B moves the lower surface film unit 300A in a predetermined direction, for example, by an electric actuator or a hydraulic actuator.

[0108] The operations of the cameras 20A and 20B, the tension adjustment feed mechanisms 30C and 50C, the position adjustment feed mechanisms 30D and 50D, the upper film unit moving mechanism 200B, and the lower film unit moving mechanism 300B are controlled by the control unit 90 .

[0109] The upper surface film 200 cut into a predetermined shape is wound on the supply roller 30A of the upper surface film supply unit 30. While adjusting the tension by the tension adjustment feeding mechanism 30C, the upper surface film supply unit 30 supplies the upper surface film 200 to the position just in front of the upper laminating roller 70A and the lower laminating roller 70B. At this time, the upper surface film unit moving mechanism 200B moves the upper surface film unit 200A as a whole, thereby adjusting the position and orientation of the upper surface film 200 in the width direction (y direction) and the surface direction (θ direction) relative to the workpiece 100, and the position adjustment feeding mechanism 30D adjusts the position of the supplied upper surface film 200 in the conveying direction (x direction).

[0110] Similarly, the lower surface film 300 cut into a predetermined shape is wound on the supply roller 50A of the lower surface film supply unit 50, and while adjusting the tension by the tension adjustment feed mechanism 50C, the lower surface film supply unit 50 supplies the lower surface film 300 to the position directly in front of the upper laminating roller 70A and the lower laminating roller 70B. At this time, the lower surface film unit moving mechanism 300B moves the lower surface film unit 300A as a whole, thereby adjusting the position and orientation of the lower surface film 300 in the width direction (y direction) and the surface direction (θ direction) of the workpiece 100, and the position adjustment feed mechanism 50D adjusts the position of the supplied lower surface film 300 in the conveying direction (x direction).

[0111] In this structure, Figure 8The laminator 1 shown captures an image of the workpiece 100 before lamination processing and detects the deviation of the workpiece 100 from the reference position and reference posture. Then, the upper surface film unit moving mechanism 200B moves the upper surface film unit 200A as a whole so that the cut upper surface film 200 wound on the supply roller 30A (or the upper surface film 200 cut into a specified shape in the upper surface film unit 200A) becomes a position and orientation suitable for the deviation state of the workpiece 100, and the position adjustment feed mechanism 30D adjusts the position in the conveying direction, so that the upper surface film 200 is temporarily attached to the workpiece 100 in a configuration suitable for the deviation state of the workpiece 100. In addition, the lower surface film unit moving mechanism 300B moves the lower surface film unit 300A as a whole, so that the cut lower surface film 300 wound on the supply roller 50A (or the lower surface film 300 cut into a specified shape in the lower surface film unit 300A) becomes the position and orientation suitable for the deviation state of the workpiece 100, and the position adjustment feed mechanism 50D adjusts the position of the conveying direction, so that the lower surface film 300 is temporarily pasted on the workpiece 100 with the configuration suitable for the deviation state of the workpiece 100. Then, the laminating machine 1 puts the workpiece 100 into the laminating process. Afterwards, the workpiece 100 and the upper surface film 200 are pressed by the upper side laminating roller 70A and the lower side laminating roller 70B, and the workpiece 100 is laminated by the upper surface film 200. Temporary pasting and lamination are also performed in the lower surface film 200.

[0112] Therefore, when pasting the film cut corresponding to the shape of the workpiece 100, it is not necessary to accurately position the workpiece 100. In addition, it is not necessary to cut the film corresponding to the position and posture of the workpiece 100, and the position and direction of the upper surface film 200 and the lower surface film 300 can be adapted to the deviation state of the workpiece 100 by moving the upper surface film unit 200A and the lower surface film unit 300A.

[0113] Therefore, the cut film can be easily attached to the workpiece 100 .

[0114] In addition, the above-mentioned embodiment is an example of the embodiment of the present invention, and various embodiments that realize the functions of the present invention are included in the scope of the present invention.

[0115] For example, in the above-mentioned embodiment, a workbench may be provided for fixing (adsorbing or adhering, etc.) the workpiece 100 for transportation after the workpiece 100 is photographed by the camera 20, so that the deviation of the workpiece 100 from the reference position and the deviation from the reference posture do not change. In this case, the detected deviation state of the workpiece 100 can be reliably maintained, and the pre-cut film can be more appropriately attached to the workpiece 100.

[0116] In addition, in the above-mentioned embodiment, the laminator 1 is not limited to a structure for continuously processing the same type of workpieces 100, and can be set to a structure for continuously attaching pre-cut films to different types of workpieces 100 having different shapes, sizes, or product field shapes. In the case of such a structure, the pre-cut film can be attached more easily and appropriately to the workpieces 100 produced in small quantities of multiple varieties.

[0117] In addition, in the above-mentioned embodiment, the front end of the upper film stripping component 34 and the lower film stripping component 54 is provided with a curved surface of a predetermined radius (the cross section along the conveying direction is a curved surface) The structural example is described, but it is not limited to this. That is, as long as it is a structure that can reduce the friction with the film, the front end of the upper film stripping component 34 and the lower film stripping component 54 can be constituted by various shapes, materials and components. For example, it can be set to be provided with a small roller at the front end of the upper film stripping component 34 and the lower film stripping component 54, the small roller rotates according to the conveying of the film, and the film is folded back at the position of the small roller. In this case, it can be set to be a structure in which the film is folded back at the position of the small roller (the front end of the upper film stripping component 34 and the lower film stripping component 54), the adhesive film can be peeled off from the substrate, and the friction between the film and the front end portion can be greatly reduced.

[0118] In addition, in the above-mentioned embodiment, the case of pre-cutting the film with a laser cutter is used as an example for description, but it is not limited to this. For example, it can also be set as a structure for cutting the film with a die-cutting roller, and the unit with the die-cutting roller is posture-controlled as a whole, and the film is cut at a position and posture corresponding to the deviation of the workpiece 100 from the reference position and the reference posture. In addition, it can also be set as a structure for cutting the film with a die-cutting plate, and the unit with the die-cutting plate is posture-controlled as a whole, and the film is cut at a position and posture corresponding to the deviation of the workpiece 100 from the reference position and the reference posture. Compared with the case of cutting with a laser cutter, when die-cutting is performed, the cutting method of the film is different, so any structure can be adopted according to the purpose. In addition, it can also be set as a laser cutter and a die-cutting unit (die-cutting roller or die-cutting plate, etc.), which are combined to cut the film.

[0119] As described above, the laminator 1 of the present embodiment includes the input unit 10 , the camera 20 , the upper and lower film supply units 30 , 50 , the upper and lower film cutting units 40 , 60 , the upper and lower laminating rollers 70A, 70B, and the control unit 90 .

[0120] The input unit 10 supplies a workpiece 100 to be processed.

[0121] The upper film supply unit 30 and the lower film supply unit 50 supply the sheet-like member (the upper film 200 and the lower film 300 ) to be attached to the workpiece 100 .

[0122] The upper laminating roller 70A and the lower laminating roller 70B attach the sheet-like member to the workpiece 100 .

[0123] The camera 20 and the control unit 90 detect the deviation state of the workpiece 100 before the sheet member is bonded together by the upper laminating roller 70A and the lower laminating roller 70B.

[0124] The upper surface film cutting section 40 and the lower surface film cutting section 60 pre-process the upper surface film 200 and the lower surface film 300 supplied by the upper surface film supply section 30 and the lower surface film supply section 50 based on the detection results of the camera 20 and the control section 90 so that the cutting position corresponds to the deviation state of the workpiece 100.

[0125] When the upper laminating roller 70A and the lower laminating roller 70B attach the sheet member to the workpiece 100 , the cut positions of the supplied upper film 200 and lower film 300 are arranged to be suitable for the offset state of the workpiece 100 .

[0126] Therefore, the cut sheet-like member can be easily attached to the workpiece 100 .

[0127] The upper film cutting unit 40 and the lower film cutting unit 60 adjust in advance the position and orientation of the sheet member cut into a predetermined shape according to the deviation state of the workpiece.

[0128] Thus, when pasting the film cut in accordance with the shape of the workpiece 100, it is not necessary to accurately position the workpiece 100. In addition, it is not necessary to cut the film in accordance with the position and posture of the workpiece 100, and the position and orientation of the upper surface film 200 and the lower surface film 300 can be adapted to the deviation state of the workpiece 100 by moving the upper surface film unit 200A and the lower surface film unit 300A.

[0129] Therefore, the cut film can be easily attached to the workpiece 100 .

[0130] The upper film cutting section 40 and the lower film cutting section 60 preliminarily cut the upper film 200 and the lower film 300 supplied by the upper film supply section 30 and the lower film supply section 50 according to the deviation state of the workpiece 100 based on the detection results of the camera 20 and the control section 90 .

[0131] Thus, when attaching the film cut according to the shape of the workpiece 100, it is not necessary to accurately position the workpiece 100. Also, since the film can be cut according to the position and posture of the workpiece 100, it is not necessary to cut the film into an expected shape with high accuracy.

[0132] Therefore, the cut film can be easily attached to the workpiece 100 .

[0133] The upper surface film supply unit 30 supplies the first sheet member (upper surface film 200 ) onto the upper surface of the workpiece 100 .

[0134] The lower surface film supply unit 50 supplies the second sheet member (lower surface film 300 ) to the lower surface of the workpiece 100 .

[0135] The upper film cutting unit 40 cuts the first sheet member (upper film 200 ) supplied from the upper film supply unit 30 in advance according to the deviation state of the workpiece 100 based on the detection results of the camera 20 and the control unit 90 .

[0136] The lower film cutting section 60 cuts the second sheet member (lower film 300 ) supplied from the lower film supply section 50 in advance according to the deviation state of the workpiece 100 based on the detection results of the camera 20 and the control section 90 .

[0137] When the upper laminating roller 70A and the lower laminating roller 70B adhere the first sheet component (upper surface film 200) and the second sheet component (lower surface film 300) to the workpiece 100, the first sheet component and the second sheet component that were pre-cut according to the deviation state of the workpiece 100 become configured to be suitable for the deviation state of the workpiece 100.

[0138] Thus, when attaching the sheet member to the upper surface and the lower surface of the workpiece 100 , the cut sheet member can be easily attached to the workpiece 100 .

[0139] The upper film cutting unit 40 and the lower film cutting unit 60 include a laser cutter for cutting the sheet-like member using laser light.

[0140] This makes it possible to cut the sheet member with a high degree of freedom according to the deviation state of the workpiece 100 and the shape of the sheet member to be attached to the workpiece 100 .

[0141] Furthermore, the laminator 1 includes an upper film peeling member 34 and a lower film peeling member 54 .

[0142] The sheet member has a structure in which a sheet member for adhesion is bonded to a base material.

[0143] The upper film peeling member 34 and the lower film peeling member 54 peel the sticking sheet member (sticking film) cut by the upper film cutting unit 40 and the lower film cutting unit 60 from the base material and transfer the peeled sheet member to the workpiece 100 .

[0144] Thus, the sticking sheet member (pre-cut sticking film, etc.) adhered to the base material can be peeled off and transferred to a position that matches the offset state of the workpiece 100 , so the cut sheet member can be easily stuck to the workpiece 100 .

[0145] The upper film peeling member 34 and the lower film peeling member 54 have front ends formed at acute angles.

[0146] The sheet member (film) is folded back at the leading ends of the upper film peeling member 34 and the lower film peeling member 54 and conveyed, whereby the sticking sheet member (sticking film) is peeled off from the base material.

[0147] Thus, the sticking sheet member can be easily peeled off from the base material and transferred to the workpiece 100 by utilizing the conveying operation of the sheet member.

[0148] The front ends of the upper film peeling member 34 and the lower film peeling member 54 are processed to reduce friction with the sheet member.

[0149] Thereby, when the sheet member is folded back at the leading ends of the upper film peeling member 34 and the lower film peeling member 54 and conveyed, it is possible to suppress a situation where the sheet member is damaged.

[0150] The embodiments of the present invention are described above, but the present invention is not limited to the above embodiments. In addition, the effects described in the embodiments are merely the best effects produced by the present invention, and the effects of the present invention are not limited to the effects described in the embodiments.
