[0047] The dimensional ratios shown in the drawings are not necessarily limited to faithfully representing the actual situation, and sometimes the dimensional ratios are exaggerated for convenience of explanation. In the following description, when referring to the concepts of up or down, it is not limited to referring to the absolute up or down, and sometimes it refers to the relative up or down in the illustrated posture.

[0048] The concept of "shaping" as used herein includes removing unwanted warping from an object to make it flat or reducing the warping when there is warping in the object. Also, the concept of "shaping" includes actively deforming an object into a desired shape when the object does not have the desired shape.

[0049] (Embodiment 1)

[0050] Refer to Figures 1 to 5 to describe the shaping device according to Embodiment 1 of the present invention. Figure 1 Fig. 101 shows the shaping device of this embodiment. The shaping device 101 includes an object support portion 10 and a heating portion 2. Figure 2 Fig. 102 shows the object support portion 10 as viewed from directly above. The object support portion 10 includes a pressing unit 20. The pressing unit 20 includes a pressing tool 21 and a driving portion 22. Figure 3 Fig. 103 shows a cross-sectional view of the object support portion 10 in the first state, Figure 4 Fig. 104 shows a cross-sectional view in the second state. Figure 5 Fig. 105 shows a situation where an object 80 is provided on the object support portion 10. In the example shown here, the object 80 includes a first resin layer 81 and a second resin layer 82. The first resin layer 81 is a plate-shaped member formed of resin. The second resin layer 82 is arranged to cover a part of one surface of the first resin layer 81. The structure of the object 80 shown here is merely an example, and it may also be other structures. For example, the object 80 may also be a structure including material layers other than resin, or may be a structure laminated with three or more layers. The object 80 may be a plate-shaped object.

[0051] The shaping device 101 includes: a pressing tool 21 for pressing the plate-shaped object 80 from the side in a state where one main surface of the object 80 is upward; and a heating portion 2 for heating the object 80.

[0052] Moreover, in the example shown here, the shaping device 101 includes a plurality of support pins 4 for supporting the object 80. The object support portion 10 includes an outer peripheral portion 11 and a base portion 12. The base portion 12 is surrounded by the outer peripheral portion 11. At least one suction port 13 and a plurality of through holes 14 are provided on the base portion 12. The plurality of support pins 4 respectively penetrate the plurality of through holes 14.

[0053] The heating portion 2 may, for example, be a structure that irradiates halogen light. The heating portion 2 may, for example, be an infrared heater. The heating portion 2 may, for example, be a structure that blows hot air. The heating method by the heating portion 2 may also be a method other than those exemplified here.

[0054] Refer to Figures 5 to 9 to describe the operation of the shaping device 101 of this embodiment.

[0055] First, as shown in Figure 5 , an object 80 is provided on the object support portion 10. At this moment, the object 80 is warped. The object 80 is supported by a plurality of support pins 4.

[0056] Next, as shown in Figure 6 , the heating unit 2 is used to heat the object 80. The object 80 is softened by heating, the warping is reduced, and it becomes a state supported by a plurality of support pins 4.

[0057] As shown in Figure 7 , the pressing unit 20 is actuated. Specifically, the pressing tool 21 is moved in the direction of arrow 93 to clamp the object 80. The object 80 is clamped by the pressing tool 21 and flexed in the direction of arrow 95. In this state, as shown by arrow 94, the plurality of support pins 4 are lowered. By lowering the support pin holding portion 5, the plurality of support pins 4 can be lowered together. As shown in Figure 8 , the plurality of support pins 4 are further lowered. Figure 8 In, all the support pins 4 are separated from the object 80. The object 80 is clamped by the pressing tool 21 in the flexed state and held. In this state, cooling is performed. After the cooling is completed, as shown by arrow 96 in Figure 9 , the plurality of support pins 4 are raised. At this time, the pressing tool 21 is retracted as shown by arrow 97. The pressing tool 21 is separated from the object 80. The object 80 is supported by the plurality of support pins 4.

[0058] Even if the object 80 initially bulges downward in the flexed layer as shown in Figure 5 , it can be temporarily deformed in the direction of bulging upward by being clamped by the pressing tool 21 after heating and cooled, so as to become a flat state as shown in Figures 7 to 8 . However, what is shown here is merely an example. As long as the heating conditions, the press-in amount pressed by the pressing tool 21, the holding time held by the pressing tool 21, etc. are adjusted to match the shape of the object 80 finally desired. Figure 9 In the present embodiment, since the pressing tool 21 for pressing the object 80 from the side is provided, a shaping device that can easily cope with even a change in the target correction amount can be realized.

[0059] In the present embodiment, an example in which the object indicating portion 10 includes the base portion 12 is shown. The presence of the base portion 12 is not essential, but preferably, as shown in the present embodiment, the base portion 12 for supporting the object 80 is provided. By adopting this structure, the object 80 can be stably supported.

[0060]

[0061] ​In the present embodiment, an example in which the base 12 includes a cooling portion is shown. Such a structure is not essential, but preferably, as shown in the present embodiment, the base 12 is provided with a cooling portion for cooling the object 80. By adopting this structure, the object 80 can be efficiently cooled.

[0062] In the present embodiment, at least one suction port 13 is provided on the base 12, and the suction port 13 is connected to a suction device (not shown). Preferably, as shown in the present embodiment, the shaping device 101 is provided with a suction device for sucking the object 80 downward. By adopting this structure, the object 80 can be held by suction.

[0063] In the present embodiment, the shaping device 101 is provided with a plurality of support pins 4 for supporting the object 80. Preferably, as shown in the present embodiment, the shaping device 101 is provided with a plurality of support pins 4 that project upward to support the object 80. By adopting this structure, the object 80 can be held by the plurality of support pins 4. Further, preferably, the plurality of support pins 4 can be raised and lowered. By adopting this structure, the object 80 can be lifted or lowered by the plurality of support pins 4.

[0064] In addition, in the present embodiment, regarding the raising and lowering of the plurality of support pins 4, an example in which all the support pins 4 are raised and lowered together in an integrated state is shown, but it is not limited thereto. For example, it may be configured such that the plurality of support pins 4 can be raised and lowered independently of each other.

[0065] As shown in the present embodiment, if a virtual plane obtained by connecting the upper ends of all the plurality of support pins 4 is assumed, it is preferable that the above-described virtual plane protrudes upward. By adopting this structure, the object 80 can be properly supported.

[0066] In addition, in the present embodiment, the object 80 is described on the premise of an example in which the object 80 is rectangular, but the shape of the object 80 is not limited to a rectangle. The shape of the object 80 may also be a square, a polygon, a circle, an ellipse, or even other shapes. The structure of the shaping device that is particularly suitable when the shape of the object 80 is a square is described in detail in Embodiments 7 and 8.

[0067] (Embodiment 2)

[0068] Refer to Figure 10 , and the shaping device according to Embodiment 2 of the present invention will be described. Figure 10The shaping device 102 of the present embodiment is shown. The shaping device 102 includes an object support portion 10, a heating portion 2, and a pressing member 3. It is possible that the heating portion 2 and the pressing member 3 can move laterally as shown by the arrow 91, for example. The heating portion 2 and the pressing member 3 can move above the object support portion 10 as needed. The shaping device 102 includes a pressing member 3 having a protrusion 6 extending downward, and can bring the end of the protrusion 6 into contact with the object 80 and press the object 80 downward.

[0069] Refer to Figure 5 , Figure 6 , Figures 11 to 14 , the operation of the shaping device 102 of the present embodiment will be described.

[0070] First, as Figure 5 shown, the object 80 is placed on the object support portion 10. At this moment, the object 80 is warped. The object 80 is supported by a plurality of support pins 4.

[0071] Next, as Figure 6 shown, the object 80 is heated using the heating portion 2. The object 80 is softened by heating, the warping is reduced, and it becomes a state supported by a plurality of support pins 4.

[0072] As Figure 11 shown, the pressing tool 21 is advanced in the direction of the arrow 93 to deform the object 80. The object 80 is deformed into a shape convex upward. The upper ends of the plurality of support pins 4 are arranged along the deformed object 80. As shown by the arrow 98 in Figure 12 , by lowering the pressing member 3, the outer edge portion of the object 80 is pressed, and the position of the outer edge portion of the object 80 in the height direction is adjusted. At this time, it is desirable to adjust so that Figure 11 the position of the left outer edge portion of the object 80 in the height direction is the same as the position of the right outer edge portion of the object 80 in the height direction. If adjusted in this way, for the left outer edge portion and the right outer edge portion of the object 80, forces are applied at the same positions in the height direction, respectively. Therefore, the object 80 can be flexed in a state closer to left - right symmetry. In this state, the object 80 is held because it is clamped by the pressing tool 21. As shown by the arrow 99 in Figure 13 , the pressing member 3 is raised, and the plurality of support pins 4 are lowered. As shown by the arrow 93 in Figure 14 , the pressing tool 21 is advanced to adjust the amount of deformation of the object 80. The object 80 flexes in the direction of the arrow 95, but the amount of this flexure is adjusted. By processing in this way, the object 80 can be made into a desired shape.

[0073] In this embodiment, the same effects as those of the structure described in Embodiment 1 can also be obtained. Moreover, since the shaping device 102 includes the pressing member 3, the object 80 can be more reliably held at a desired position.

[0074] Refer to Figure 15 Another usage method of the pressing member 3 will be described. Figure 15 In, the deformation of the object 80 due to heating is insufficient, and the outer edge portion of the object 80 remains in a state above the upper end of the pressing tool 21. Even if the pressing tool 21 is advanced while maintaining this state, the outer edge portion of the object 80 cannot be captured. Therefore, as a countermeasure, the pressing member 3 can be considered. In Figure 15 In the state shown in, by lowering the pressing member 3 to press the outer edge portion of the object 80, the position of the outer edge portion of the object 80 can be lowered. In this state, when the pressing tool 21 is advanced, the object 80 can be clamped and held by the pressing tool 21.

[0075] In the state where the object 80 is clamped and held by the pressing tool 21, as Figure 16 shown by the arrow 94 in, a plurality of support pins 4 can be lowered to completely separate from the object 80. By advancing the pressing tool 21 in the direction of the arrow 93, the object 80 deflects in the direction of the arrow 95. Alternatively, cooling can be performed in this state.

[0076] In addition, the form of the protrusion 6 of the pressing member 3 is not limited to the Figure 10 example shown in etc. The protrusion 6 is not limited to a fixed structure, and can also be a structure that can be replaced at any number and any position. It can also be a structure in which the length of the protrusion 6 can be individually expanded and contracted. It can also be configured such that the length of each protrusion 6 can be changed by replacement or expansion and contraction, thereby enabling various deformations of the form of one pressing member 3.

[0077] (Embodiment 3)

[0078] Refer to Figures 17 to 18 to describe the shaping device according to Embodiment 3 of the present invention. Figure 17 The object support portion 10 of the shaping device of this embodiment is shown. In this shaping device, the pressing unit 20 is provided only on one side of the object support portion 10. Figure 18 The situation where the object 80 is provided in the shaping device of this embodiment is shown. On the side opposite to the pressing unit 20, the object 80 is pressed against the outer peripheral portion. Alternatively, as Figure 18 shown in, this shaping device includes the pressing member 3.

[0079] In this embodiment, the same effects as those of the structure described in Embodiment 1 can also be obtained. In this embodiment, the number of pressing units 20 can be reduced, and thus, the structure of the shaping device can be simplified. As a result, the number of components of the shaping device can be reduced.

[0080] (Embodiment 4)

[0081] Refer to Figures 19 to 20 , and the shaping device according to Embodiment 4 of the present invention will be described. Figure 19 The object support portion 10 of the shaping device of this embodiment is shown. In the shaping device of this embodiment, the base portion 12 does not have a cooling portion. The outer peripheral portion 11 and the base portion 12 are integrally formed of the same material. In this way, it can also be configured that the base portion 12 does not have a cooling portion. Alternatively, the cooling may be performed by the action of a certain device provided at a portion other than the base portion 12. Or, alternatively, the cooling may not be implemented by a cooling portion that actively cools, but may be performed by natural heat dissipation to the surroundings.

[0082] Figure 20 The object support portion 10 of a modification example of the shaping device of this embodiment is shown. In Figure 20 the example shown, the pressing unit 20 is provided only on one side. Such a structure is also possible.

[0083] In this embodiment, the same effects as those of the structure described in Embodiment 1 can also be obtained. In this embodiment, the structure of the object support portion 10 can be simplified corresponding to the fact that the base portion 12 of the object support portion 10 does not have a cooling portion.

[0084] (Embodiment 5)

[0085] Refer to Figure 21 , and the shaping device according to Embodiment 5 of the present invention will be described. Figure 21 The object support portion 10 of the shaping device of this embodiment is shown. In the shaping device of this embodiment, the pressing unit 20 is provided with a stopper portion 23. A protrusion, that is, a stopper portion 23, for restricting the upward displacement of the object 80 is provided on the pressing tool 21. More specifically, the stopper portion 23 is provided as a protrusion that protrudes forward at the upper part of the end face of the pressing tool 21. However, the form of the stopper portion 23 shown here is merely an example. As the stopper portion 23, a form that can restrict the upward displacement of the outer edge portion of the object 80 is sufficient, and is not limited to Figure 21 the form shown. As the stopper portion 23, it is not limited to Figure 21The first - order step as shown can also be in the form including two or more steps. As the stopper portion 23, it can also be in the form with an inverted slope. The stopper portion 23 is not limited to a protrusion. For example, it can also be that an anti - slip processed area is provided on the surface of the pressing tool 21 that contacts the object 80, and this area is used as the stopper portion 23. If a hypothetical plane obtained by connecting the upper ends of a plurality of support pins 4 is assumed, the hypothetical plane protrudes downward.

[0086] In the present embodiment, since the stopper portion 23 is provided on the pressing tool 21, it is possible to prevent the end portion of the object 80 from sliding excessively and being greatly displaced above the object support portion 10 or falling off from the object support portion 10.

[0087] In addition, Figure 21 shows an example where the pressing units 20 are provided on both sides. However, as a first modification example, as Figure 22 shown, it can also be configured such that the pressing unit 20 is provided only on one side. In Figure 22 shown in the first modification example, one end portion of the object is pressed against the outer peripheral portion 11. However, in order to prevent the end portion of the object 80 from sliding excessively upward, as Figure 23 shown in the second modification example, a stopper portion 24 can be provided on the outer peripheral portion 11 on the side where there is no pressing unit 20. The stopper portion 24 is provided as a protrusion protruding at the upper part of the inner peripheral surface of the outer peripheral portion 11.

[0088] Figures 21 to 23 shows an example where the base portion 12 of the object support portion 10 has a cooling portion. However, it can also be configured as in Figure 24 shown in the third modification example or Figure 25 shown in the fourth modification example such that the base portion 12 of the object support portion 10 does not have a cooling portion. If so, the structure of the object support portion 10 can be simplified corresponding to the base portion 12 of the object support portion 10 not having a cooling portion.

[0089] In addition, if a hypothetical plane obtained by connecting all the upper ends of a plurality of support pins 4 is assumed, it is preferable that the above - mentioned hypothetical plane protrudes downward. By adopting this structure, the object 80 can be properly supported.

[0090] (Embodiment 6)

[0091] Referring to Figures 26 to 27 , the shaping device according to Embodiment 6 of the present invention can be described. Figure 26 shows the shaping device of the present embodiment. The shaping device of the present embodiment does not have a plurality of support pins for supporting the object 80. The base portion 12 has a convex or concave upper surface that abuts against the object 80. In Figure 26In the example shown, as an example, the base 12 has a convex upper surface that abuts against the object 80.

[0092] As a modification, as Figure 27 shown, it may also be configured such that the pressing unit 20 is provided only on one side of the object support portion 10.

[0093] Refer to Figures 28 to 31 to describe the operation of the shaping device of this embodiment.

[0094] First, as Figure 28 shown, the object 80 is placed on the object support portion 10 and heated. At the moment when the heating is completed, the object 80 warps. The object 80 is supported by the convex upper surface of the base 12. The pressing member 3 descends in the direction of arrow 98 and presses down on the outer edge portion of the object 80. By the pressing member 3, the floating position of the object 80 is adjusted to an appropriate position.

[0095] As Figure 29 shown by arrow 99 in, the pressing member 3 rises. The pressing tool 21 of the pressing unit 20 advances as shown by arrow 93 and clamps the object 80. As a result, the object 80 flexes. In this state, cooling is performed. In this way, the object 80 is shaped into a desired shape.

[0096] The same applies to the structure of the modification in which the pressing unit 20 is provided only on one side of the object support portion 10. That is, as Figure 30 shown, the pressing member 3 descends in the direction of arrow 98 and presses down on the outer edge portion of the object 80. By the pressing member 3, the floating position of the object 80 is adjusted to an appropriate position. As Figure 31 shown by arrow 99 in, the pressing member 3 rises. The pressing tool 21 of the pressing unit 20 advances as shown by arrow 93 and presses the object 80 against the outer peripheral portion 11. As a result, the object 80 flexes. In this state, cooling is performed. In this way, the object 80 is shaped into a desired shape.

[0097] (Embodiment 7)

[0098] Refer to Figures 32 to 35 to describe the shaping device according to Embodiment 7 of the present invention. Figure 32 The object support portion 10i of the shaping device of this embodiment is shown. This shaping device is a device for processing a square object 80. Figure 33 Shows a cross-sectional view in the direction of the arrow related to the line XXXIII-XXXIII of Figure 32 .

[0099] When the shape of the object 80 is rectangular, warping is almost limited to warping such that the long side flexes when viewed from the side perpendicular to the long side. Therefore, it can be processed by pressing the short side of the object 80 with the pressing tool 21. However, when the shape of the object 80 is square, there is no concept of long side / short side, and it is not certain in which direction warping occurs. In such an object 80, there can be multiple warping modes. Therefore, for the object 80 with a square shape, it is preferable to use the object support portion 10i as shown in the present embodiment.

[0100] The forming device of the present embodiment includes an object support portion 10i. The object support portion 10i has a square outer peripheral portion 11. Pressing units 20 are respectively provided at four corner portions of the outer peripheral portion 11. The pressing unit 20 includes an L-shaped pressing tool 21 and a driving portion 22. The pressing tool 21 and the driving portion 22 are connected by a shaft that penetrates the outer peripheral portion 11. However, the shape of the pressing unit 20 shown here is merely an example after all. The form in which the shaft penetrates the outer peripheral portion 11 is also merely an example after all. It may also be that there are some notches provided on the outer peripheral portion 11 for setting the pressing unit 20. The shape of the pressing unit 20 shown here is merely an example after all and is not limited to this case. For example, the structure of the shaft connecting the pressing tool 21 and the driving portion 22 is not limited to the structure shown in the figure.

[0101] Figures 34 to 35 A case where one corner portion of the object support portion 10i is enlarged is shown. Here, the operation of the pressing unit 20 will be described.

[0102] Figure 34 A state where the pressing tool 21 has retreated the farthest is shown. By the operation of the driving portion 22, the pressing tool 21 retreats as shown by the arrow 97. The outer contour line of the object 80 is indicated by a double-dot chain line. In this state, the pressing tool 21 is sufficiently separated from the object 80.

[0103] Figure 35 A state where the pressing tool 21 has advanced is shown. By the operation of the driving portion 22, the pressing tool 21 advances as shown by the arrow 93. The pressing tool 21 abuts against the corner portion of the object 80 and presses the object 80 in the direction along the diagonal of the object 80.

[0104] As described above, the forming device of the present embodiment includes: a pressing tool 21 for pressing the object 80 from the side in a state where the plate-shaped object 80 is arranged with one main surface facing upward; and a heating portion 2 for heating the object 80.

[0105] In addition, the "pressing from the side" as mentioned herein includes not only pressing in a direction perpendicular to the side of the object, but also pressing the corner portion of the object along a diagonal direction. For example, if the object 80 is circular, "pressing from the side" the object 80 also includes the concept of pressing the object 80 along the radial direction.

[0106] In the present embodiment, a pressing unit 20 including a pressing tool 21 having an L-shaped configuration is provided at each corner portion of the object support portion 10i of the shaping device, and the corner portion of the object 80 can be pressed along a diagonal direction by the pressing tool 21. Therefore, even when the shape of the object 80 is square, shaping can be appropriately performed.

[0107] (Embodiment 8)

[0108] Refer to Figures 36 to 37 , and a shaping device according to Embodiment 8 of the present invention will be described. Figure 36 The object support portion 10i and the pressing member 3 of the shaping device of the present embodiment are shown. Figure 37 Shown in relation to Figure 36 A cross-sectional view taken along the arrow direction of line XXXVII-XXXVII of. The shaping device of the present embodiment includes a pressing member 3 having a protrusion 6 extending downward, and the end of the protrusion 6 can be brought into contact with the object 80 to press the object 80 downward. As Figure 36 shown, when viewed from above, the four protrusions 6 are respectively arranged at the four corner portions of the pressing member 3. Figure 36 In, the four protrusions 6 are on the back side of the pressing member 3 and thus cannot be directly seen, and are therefore represented by dashed lines.

[0109] In the present embodiment, the effects described in Embodiment 7 can be obtained. And in the present embodiment, since the pressing member 3 is provided, the object 80 can be more reliably held at a desired position.

[0110] (Modification)

[0111] In addition, refer to Figures 38 to 39 to describe a modification of the shaping device applicable to any one of Embodiments 7 and 8.

[0112] In Figure 38In the example shown, the pressing unit 20 is provided only at one corner of the square object support portion 10i. The pressing tool 21 included in the pressing unit 20 can move forward and backward as shown by arrows 93 and 97 due to the operation of the driving unit 22. When the pressing tool 21 moves forward, the object 80 is pressed by the pressing tool 21 in the diagonal direction, and the object 80 is pressed against the corner portion of the outer peripheral portion 11 at a position facing the pressing unit 20. In this way, the object 80 is sandwiched and held between the pressing tool 21 and the outer peripheral portion 11. The shaping device having such a structure can also appropriately shape the square object 80.

[0113] In Figure 39 In the example shown, the pressing units 20 are provided only at two mutually facing corner portions of the square object support portion 10i. The pressing tools 21 respectively included in the two pressing units 20 can move forward and backward as shown by arrows 93 and 97 due to the operation of the driving unit 22. When the two pressing tools 21 move forward, the object 80 is sandwiched and held by the pressing tools 21 in the diagonal direction. The shaping device having such a structure can also properly shape the square object 80.

[0114] In addition, multiple embodiments in the above-described embodiments can be appropriately combined and employed.

[0115] In addition, all aspects of the above-described embodiments disclosed this time are illustrative and not restrictive. The scope of the present invention is shown by the claims, including all modifications within the meaning and scope equivalent to the claims.
