[0020] For the purpose of clarity of explanation, the following description and drawings are appropriately omitted or simplified. In addition, in each drawing, the same elements are denoted by the same reference numerals, and repeated explanation is omitted as needed.

[0021] Implementation Method 1

[0022] The stacking forming system described below applies a pressing force to press the movable disk toward the fixed plate side when the stacked body is located between the fixed disk and the movable disk, thereby forming a stacked formed product with an adjusted thickness of the stacked body. The shape, form, and size of the stacked body are not particularly limited. The stacked body can be a metal plate or a copper-clad laminate (CCL) with copper foil attached to an insulating material. In this embodiment, the following stacking forming system is described, which uses a stacked body in which a stacked film is placed on a substrate having a concave-convex surface and a prescribed wiring pattern as an example of a stacked body, and produces a stacked formed product by using a plurality of stacking forming devices to perform prescribed shaping on the stacked body in stages.

[0023] exist Figure 1 A schematic diagram of the stacking forming system 1 according to the first embodiment is shown in FIG. Figure 1 As shown, the lamination forming system 1 of the first embodiment includes a film unwinding device 10, a vacuum laminating device 11, flat press devices 12 and 13, and a film winding device 14. In this lamination forming system 1, the vacuum laminating device 11 and the flat press devices 12 and 13 all correspond to the lamination forming device.

[0024] In the lamination system 1 of Embodiment 1, the vacuum laminator 11 and the flat presses 12 and 13 are arranged between a film unwinding device 10 and a film take-up device 14. The film unwinding device 10 unwinds a carrier film with the laminated object placed on the carrier film. The film take-up device 14 then takes up the carrier film, thereby removing the laminated object that has been pressurized by the vacuum laminator 11 and the flat presses 12 and 13. Specifically, the direction from the film unwinding device 10 toward the film take-up device 14 is the direction in which the laminated object is conveyed.

[0025] Furthermore, the stacking forming system 1 of embodiment 1 arranges the vacuum stacking device 11 and the flat punching devices 12 and 13 in a continuous and adjacent manner from the transport source to the transport destination. Furthermore, in the stacking forming system 1, by moving the stacked body in the order of the vacuum stacking device 11, the flat punching devices 12, and 13 while applying pressure to the stacked body using each device, the thickness of the stacked body is adjusted to a target value while reducing thickness variations. Although the vacuum stacking device 11 and the flat punching devices 12 and 13 differ in terms of the presence or absence of a chamber and the method of pressurization control, they all share the same structure of using a pressing force generating mechanism incorporated into a drive unit (e.g., a lower plate drive unit) to press the movable plate against the fixed plate.

[0026] That is, in the stacking forming system 1 of embodiment 1, there are multiple stacking forming devices, each of which has: a fixed disk, which is provided with a first hot plate for applying a specified temperature to the stacked body; a movable disk, which is located at a position opposite to the fixed disk and is provided with a second hot plate for applying a specified temperature to the stacked body; and a pressing force generating mechanism, which transmits a pressing force to a pressure point set at a specified position of the movable disk in order to make the movable disk approach the fixed disk side to press the stacked body. Moreover, in the stacking forming system 1 of embodiment 1, for each of the multiple stacking forming devices, the setting position of the pressure point is set at a position different for each stacking forming device, and the multiple stacking forming devices arranged along the conveying direction of the stacked body are used to apply a pressing force to the stacked body in sequence, thereby successively improving the flatness of the stacked body to form a stacked product. Here, below, the basic structure of the stacking forming device is explained by taking the vacuum laminating device 11 as an example.

[0027] exist Figure 2 A schematic diagram of the vacuum lamination device 11 according to the first embodiment is shown in FIG. Figure 2 As shown, the vacuum lamination device 11 includes a base plate 20, tie rods 21, a fixed plate 22, and a movable plate 23. In the vacuum lamination device 11, the base plate 20 and the movable plate 23 are connected by the tie rods 21, and the movable plate 23 is assembled in such a manner that the tie rods 21 are inserted into the insertion holes provided at the four corners of the fixed plate 22. Figure 2 In the example shown, an upper hot plate 25b is installed on the fixed disk 22 across the insulation plate 24a, and a lower hot plate 25a is installed on the movable disk 23 across the insulation plate 24b. The upper hot plate 25b and the lower hot plate 25a are a type of pressure plate. The pressure plate transmits pressure to the stacked molded product on which the stacked material is loaded. In addition, the pressure mechanism is not particularly limited as long as it is a structure that applies pressure to the stacked molded product. For example, it can be a plate-like component (hot plate) that can be heated and cooled, or it can be a flexible sheet that can be heated and cooled. Accordingly, the stacked molded product can be well formed.

[0028] In addition, the vacuum laminating device 11 is described as having a structure having the following mechanism as a pressing force generating mechanism, that is, the mechanism rotates the ball screw shaft by a servo motor to raise and lower the ball screw nut, thereby raising and lowering the movable plate 23. Moreover, in the vacuum laminating device 11, at least two sets of ball screws are used to pressurize one lower hot plate 25a based on at least two pressure points. Figure 2 In the example shown, the vacuum laminating device 11 is shown to have two sets of ball screws. Alternatively, the pressing force generating mechanism may be a mechanism that rotates the ball screw nut using a servo motor to move the ball screw shaft up and down, thereby moving the movable plate 23 up and down.

[0029] like Figure 2 As shown, the pressing force generating mechanism of the vacuum laminating device 11 includes motors 261, 262, ball screw shafts 271, 272, ball screw nuts 281, 282, and pressing force dispersing plates 291, 292. Figure 2 Although not shown in the figure, there are cases where other components such as a speed reducer are interposed between the motor and the ball screw shaft.

[0030] Here, the first group of the motor 261, the ball screw shaft 271, the ball screw nut 281, and the pressing force dispersion plate 291 has the same structure as the second group of the motor 262, the ball screw shaft 272, the ball screw nut 282, and the pressing force dispersion plate 292. Therefore, the structure of the pressing force generating mechanism will be described using the first group as an example, and the description of the second group will be omitted. In the pressing force generating mechanism, the ball screw shaft 271 is rotated by the motor 261. Moreover, the ball screw nut 281 is raised and lowered by the rotation of the ball screw shaft 271. A pressing force dispersion plate 291 is provided at the end of the ball screw nut 281 on the movable disk 23 side. The pressing force dispersion plate 291 is a structure in which a plurality of plates are stacked in a manner such that the area gradually increases from the ball screw nut 281 toward the movable disk 23. By increasing the area in multiple stages in this manner, the pressing force transmitted from the ball screw nut 281 is dispersed to the movable plate 23 , and the pressing force applied to the stacked body via the movable plate 23 is made uniform in the surface direction of the stacked body.

[0031] In the stacking forming system 1 of the first embodiment, the positions of the pressure points of the multiple stacking forming devices are set to be different for each stacking forming device. Here, the method for setting the pressure points in the stacking forming system 1 of the first embodiment is described below. In the following description, the center position of the cross section in a direction perpendicular to the direction of elevation of the ball screw shaft 272 is referred to as the pressure point.

[0032] exist Figure 3, which illustrates an example of setting a pressurizing point in the stacking molding system 1 according to the first embodiment. Figure 3 In FIG, the positions of the ball screw nuts set for the vacuum laminating device 11, the flat press device 12, and the flat press device 13, the positions of the pressure points corresponding to the positions of the ball screw nuts, and the position of the lower hot plate 25a are shown. Figure 3 The conveying axis TX and the orthogonal axis Xa are shown in FIG. The conveying axis TX is an axis extending in the conveying direction from the center position of the second pressurizing plate (e.g., the lower hot plate 25a) in the orthogonal direction. The orthogonal axis Xa is an axis extending in the orthogonal direction from the center position of the lower hot plate 25a on the conveying axis TX. Furthermore, the pressurizing center point P0 coincides with the intersection of the conveying axis TX and the orthogonal axis Xa.

[0033] In the stacking forming system of embodiment 1, the plurality of stacking forming devices include at least two stacking forming devices from the first stacking forming device to the third stacking forming device. In the first stacking forming device (vacuum stacking device 11), the plurality of pressurizing points include a first pressurizing point and a second pressurizing point arranged at positions that are line-symmetrical with respect to the orthogonal axis Xa. In the second stacking forming device (flat punching device 12), the plurality of pressurizing points include a third pressurizing point and a fourth pressurizing point arranged at positions that are point-symmetrical with respect to the pressurizing center point across the conveying axis TX. In the third stacking forming device (flat punching device 13), the plurality of pressurizing points include a fifth pressurizing point and a sixth pressurizing point arranged at positions that are line-symmetrical with respect to the orthogonal axis Xa and the fourth pressurizing point. That is, the stacked body is pressed at different pressurizing points by the first stacking forming device, the second stacking forming device, and the third stacking forming device, respectively.

[0034] exist Figure 3 In the illustrated lamination system, a first lamination unit is employed in the vacuum lamination apparatus 11, a second lamination unit is employed in the flat press apparatus 12, and a third lamination unit is employed in the flat press apparatus 13. Specifically, the vacuum lamination apparatus 11 has ball screw nuts 281 and 282 arranged so that pressure points PX11 and PX12 are located at line-symmetrical positions about the orthogonal axis Xa. Furthermore, in the vacuum lamination apparatus 11, both pressure points PX11 and PX12 are located on the conveying axis TX.

[0035] The flat press device 12 is configured such that the pressure points PX21 and PX22 are arranged at positions symmetrical to each other with respect to the pressure center point P0 of the lower hot plate 35a. Figure 3In the illustrated example, the pressurizing point PX21 and the pressurizing point PX22 are arranged on a diagonal line Xa that passes through the pressurizing center point P0 and is inclined at an angle θ with respect to the conveying axis TX.

[0036] The flat press device 13 is configured such that the pressure points PX31 and PX32 are arranged at positions symmetrical to each other with respect to the pressure center point P0 of the lower hot plate 45a. Figure 3 In the example shown, pressure points PX31 and PX32 are located on a diagonal line Xb that passes through the center of pressure point P0 and is inclined at an angle θ relative to the transport axis TX. Furthermore, pressure points PX31 and PX32 are located at positions symmetrical to pressure points PX21 and PX22 of the second stacking device (e.g., the flat press device 12) about the orthogonal axis Xa.

[0037] Furthermore, in the stacking molding system 1, the positions of the press points are set so that the pressing histories of the vacuum laminating device 11 and the flat press devices 12 and 13 overlap with each other ( Figure 3 ), the number of pressure points is greater than the number of pressure points set in one stacking forming device, and the positions of the pressure points are evenly dispersed within the surface of the lower hot plate with the pressure center point P0 as the center. More specifically, in the stacking forming system 1, the vacuum stacking device 11 and the flat punching devices 12 and 13 each have two pressure points, but looking at the stacking forming system 1 as a whole, pressure points PX11, PX12, PX21, PX22, PX31, and PX32 are set at six different positions within the surface of the lower hot plate. In addition, in the stacking forming system 1, the pressure points PX11, PX12, PX21, PX22, PX31, and PX32 are set to be evenly dispersed within the surface of the lower hot plate. That is, when all the pressure points are added up, the stacked body as a whole is evenly pressed.

[0038] As described above, the stacking forming system 1 of the first embodiment includes multiple stacking forming devices, each of which includes a pressure generating mechanism for applying pressure to a pressure plate (e.g., a lower hot plate) at multiple points, with the pressure points being positioned differently between the multiple stacking forming devices. Thus, the stacking forming system 1 of the first embodiment utilizes multiple stacking forming devices to perform stacking in stages, thereby applying a uniform pressure to the entire stacked body and enabling more precise adjustment of the thickness of the stacked product.

[0039] In particular, when a laminated body is used as a laminated body in which a laminated film is placed on a substrate having a predetermined wiring pattern with uneven surfaces, a highly precise laminated molded product can be formed with its thickness more precisely adjusted. Furthermore, when manufacturing a multi-layer laminated molded product formed by repeatedly laminating laminated films, the thickness error of the laminated molded product accumulates with each repetition of the lamination process, making it important to more precisely adjust the thickness of the laminated molded product for each layer. Consequently, the effects of applying the laminated molding system 1 of Embodiment 1 can be further improved.

[0040] Implementation Method 2

[0041] In Embodiment 2, a stacking forming system 2 of another form of the stacking forming system 1 of Embodiment 1 is described. In the description of Embodiment 2, components identical to those described in Embodiment 1 are denoted by the same reference numerals as in Embodiment 1 and their description is omitted.

[0042] Here, in Figure 4 A schematic diagram of the stacking forming system 2 according to the second embodiment is shown in FIG. Figure 4 In the stacking molding system 2 of the second embodiment, two stacking molding apparatuses are arranged continuously adjacent to each other. In the stacking molding system 2 of the second embodiment, as combinations of the two stacking molding apparatuses, a first example of a combination of a vacuum stacking apparatus 11 and a flat press apparatus 15 and a second example of a combination of a vacuum stacking apparatus 16 and a flat press apparatus 17 will be described.

[0043] Here, in Figure 5 1 is a diagram illustrating a first example of setting examples of pressurizing points in the stacking molding system 2 according to the second embodiment. Figure 5 In the first example shown, a first lamination forming apparatus is used as the vacuum lamination apparatus 11, and a fourth lamination forming apparatus is used as the flat press apparatus 15. The first lamination forming apparatus includes a first and a second pressure point arranged at line-symmetrical positions about the orthogonal axis Xa. The fourth lamination forming apparatus includes a seventh and an eighth pressure point arranged at line-symmetrical positions about the conveying axis TX.

[0044] More specifically, the vacuum lamination apparatus 11 arranges the ball screw nut 281 and the ball screw nut 282 so that the pressure points PX11 and PX12 are located at positions lineally symmetrical about the orthogonal axis Xa. Furthermore, in the vacuum lamination apparatus 11, both the pressure points PX11 and PX12 are located on the conveying axis TX.

[0045] The flat press device 15 has ball screw nuts 381 and 382 arranged so that the pressure points PX21 and PX22 are located line-symmetrically about the conveying axis TX. Furthermore, in the flat press device 15, the pressure points PX21 and PX22 are both located on the orthogonal axis Xa.

[0046] In the first example of the stacking molding system 2, the positions of the press points are set so that the pressing histories of the vacuum laminating device 11 and the flat press device 15 are overlapped so that the positions of the respective press points overlap ( Figure 5 ), the number of pressure points is greater than the number of pressure points set in one stacking forming device, and the positions of the pressure points are evenly dispersed within the surface of the lower hot plate with the pressure center point P0 as the center. More specifically, in the first example of the stacking forming system 2, the vacuum stacking device 11 and the flat punching device 15 each have two pressure points, but looking at the first example of the stacking forming system 2 as a whole, pressure points PX11, PX12, PX21, and PX22 are set at four different positions within the surface of the lower hot plate. In addition, in the first example of the stacking forming system 2, the pressure points PX11, PX12, PX21, and PX22 are set to be evenly dispersed on concentric circles with the pressure center point P0 of the lower hot plate as the center.

[0047] Next, in Figure 6 1 is a diagram illustrating a first example of setting examples of pressurizing points in the stacking molding system 2 according to the second embodiment. Figure 6 In the second example shown, a second lamination forming apparatus is used as the vacuum lamination apparatus 16, and a third lamination forming apparatus is used as the flat press apparatus 17. Furthermore, the second lamination forming apparatus includes a third and a fourth pressing point, which are arranged at positions symmetrically with respect to the pressurization center point, across the conveying axis TX. The third lamination forming apparatus includes a fifth and a sixth pressing point, which are arranged at positions symmetrically with respect to the third and fourth pressing points, with respect to the orthogonal axis Xa.

[0048] More specifically, the vacuum laminating device 16 arranges the ball screw nut 281 and the ball screw nut 282 so that the pressure points PX11 and PX12 are arranged at positions symmetrical to each other with respect to the pressure center point P0 of the lower side hot plate 25a. Figure 6 In the illustrated example, the pressurizing point PX11 and the pressurizing point PX22 are arranged on a diagonal line Xa that passes through the pressurizing center point P0 and is inclined at an angle θ with respect to the conveying axis TX.

[0049] The flat punching device 17 is configured such that the pressure point PX21 and the pressure point PX22 are arranged at positions symmetrical to each other with respect to the pressure center point P0 of the lower side hot plate 35a. Figure 6 In the example shown, pressure points PX21 and PX22 are located on a diagonal line Xb that passes through the center of pressure point P0 and is inclined at an angle θ relative to the transport axis TX. Furthermore, pressure points PX21 and PX22 are located at positions symmetrical to pressure points PX11 and PX12 of the second lamination forming apparatus (e.g., vacuum lamination apparatus 16) about the orthogonal axis Xa.

[0050] In the second example of the stacking molding system 2, the positions of the press points are set so that the pressing histories of the vacuum laminating device 16 and the flat press device 17 are overlapped so that the positions of the respective press points overlap ( Figure 6 ), the number of pressure points is greater than the number of pressure points set in one stacking forming device, and the positions of the pressure points are evenly dispersed within the surface of the lower hot plate with the pressure center point P0 as the center. More specifically, in the second example of the stacking forming system 2, the vacuum stacking device 16 and the flat punching device 17 each have two pressure points, but looking at the second example of the stacking forming system 2 as a whole, pressure points PX11, PX12, PX21, and PX22 are set at four different positions within the surface of the lower hot plate. In addition, in the second example of the stacking forming system 2, the pressure points PX11, PX12, PX21, and PX22 are set to be evenly dispersed at the four corners of a square with the pressure center point P0 as the center of the lower hot plate.

[0051] According to the above description, in a stacking forming system having multiple stacking forming devices including a pressing force generating mechanism for applying pressing force to a pressure plate (for example, a lower hot plate) at multiple points, and different pressure point positions are set for each of the multiple stacking forming devices, in order to more preferably adjust the thickness of the stacking formed product, it is preferred to set the pressure points of each stacking forming device in a manner that the multiple pressure points are dispersed with the pressure center point P0 as the center.

[0052] Implementation 3

[0053] In the third embodiment, a mechanism for setting the pressurization point at an arbitrary position is described. Figure 7 FIG. 3 shows a diagram illustrating a moving mechanism of a pressurizing point in a vacuum laminating device 11 according to a third embodiment. Figure 7 As shown, the third embodiment 11 has rails 51 and 52 on the base plate 20.

[0054] The rail 51 supports a pressing force generating mechanism (e.g., the motor 261, the ball screw shaft 271, the ball screw nut 281, and the pressing force dispersing plate 291) so that the pressure point PX11 can move in at least one of the conveying direction and a direction orthogonal to the conveying direction. The rail 52 supports a pressing force generating mechanism (e.g., the motor 262, the ball screw shaft 272, the ball screw nut 282, and the pressing force dispersing plate 292) so that the pressure point PX21 can move in at least one of the conveying direction and a direction orthogonal to the conveying direction.

[0055] exist Figure 7 In the example shown, by moving the center of the ball screw nut 281 to the position P11 on the rail 51, the pressure point PX11 can be set at the same position as Figure 3 By moving the center of the ball screw nut 281 to the position P12 on the track 51, the pressure point PX11 can be set to the same position as the pressure point PX31. Figure 3 By moving the center of the ball screw nut 281 to the position P13 on the track 51, the pressure point PX11 can be set to the same position as the pressure point PX21. Figure 5 By moving the center of the ball screw nut 282 to the position P21 on the track 51, the pressure point PX12 can be set to the same position as the pressure point PX22. Figure 3 By moving the center of the ball screw nut 282 to the position P22 on the track 51, the pressure point PX12 can be set to the same position as the pressure point PX32. Figure 3 By moving the center of the ball screw nut 282 to the position P23 on the track 51, the pressure point PX12 can be set to the same position as the pressure point PX22. Figure 5 The pressure point is at the same position as PX21.

[0056] The pressure generating mechanism can also support the pressure point in such a manner that the pressure point can be freely moved in the front, back, left, right, and tilt directions within the base plate 20. However, by utilizing the track to limit the direction and amount of movement to only the setting range of the track, the position setting accuracy of the pressure point and the workload required for movement can be reduced compared to the case where the pressure point is moved in a free direction. Moreover, in the case of moving the position of the pressure generating mechanism, it is preferred to have a position detection mechanism for detecting the position of the pressure point and a display mechanism (such as a monitor) for visually displaying the position of the pressure point. By visually displaying the position of the pressure point on the monitor in this manner, the pressure point can be moved to the desired position with greater precision.

[0057] Furthermore, by providing rails 51 and 52, the positions of the pressure points set in each stacking forming apparatus can be changed to suit the arrangement order of the stacking forming apparatuses arranged in a continuous manner, thereby increasing the degree of freedom in the arrangement of the stacking forming apparatuses that can be handled by a single stacking forming apparatus. Furthermore, by configuring the positions of the pressure points to be movable in this manner, the pressure points can be set according to the type and size of the objects to be stacked, thereby increasing the number of objects to be stacked that can be handled by a single stacking forming apparatus.

[0058] In addition, the present invention is not limited to the above-described embodiment, and can be appropriately modified within a scope not departing from the gist of the invention.

[0059] This application claims the benefit of priority based on Japanese patent application No. 2023-57223, filed on March 31, 2023, the disclosure of which is incorporated herein in its entirety.
