Summary of the Invention
Problems to be Solved by the Invention
[0004] During pressing, the transport film may stick to one of the plates, and subsequent transport may not be possible.
[0005] The present invention has been made in view of the above points, and an object thereof is to suppress abnormal transport due to sticking of a transport film in a laminating device for laminating a film on a base material.
Means for Solving the Problems
[0006] This laminating device is a laminating device for laminating a film on a base material, and includes a pressing unit that presses a laminating object transported while being sandwiched between two transport films, and a moving mechanism that is disposed on the upstream side and the downstream side of the pressing unit and is capable of moving the two transport films upward and downward.
Effects of the Invention
[0007] According to the disclosed technology, in a lamination apparatus that laminates a film onto a substrate, it is possible to suppress transport abnormalities caused by the transport film sticking to the substrate. [Brief explanation of the drawing]
[0008] [Figure 1] This is a schematic diagram illustrating a lamination apparatus according to this embodiment. [Figure 2] This is a schematic diagram illustrating the lamination method according to this embodiment. [Figure 3] This diagram illustrates the drive mechanism of the transport assist roller. [Modes for carrying out the invention]
[0009] The embodiments for carrying out the invention will be described below with reference to the drawings. In each drawing, the same reference numerals are used for identical components, and redundant explanations may be omitted.
[0010] Figure 1 is a schematic diagram illustrating a lamination apparatus according to this embodiment. The lamination apparatus 1 shown in Figure 1 is an apparatus for laminating a film onto a substrate. 300 indicates the object to be laminated.
[0011] In the example shown in Figure 1, the object to be laminated 300 comprises a base material 310, a first film 320 positioned on the upper side of the base material 310, and a second film 330 positioned on the lower side of the base material 310. The base material 310 is, for example, a base material for a build-up substrate, which has irregularities such as wiring 315. The first film 320 and the second film 330 are, for example, semi-cured films that become insulating layers of the build-up substrate when heated and cured. The object to be laminated may also have a structure in which the film is positioned on only one side of the base material.
[0012] The lamination device 1 includes a feeding unit 10, a winding unit 20, a first pressing unit 30, a second pressing unit 40, a third pressing unit 50, and a plurality of transport auxiliary rollers 60. The feeding unit 10 is a device that feeds out the transport films 71 and 72. The winding unit 20 is a device that winds up the transport films 71 and 72.
[0013] The feeding unit 10 feeds out the object to be laminated 300 by sandwiching it between the transport film 71 and the transport film 72, and the winding unit 20 winds up the transport films 71 and 72 with the object to be laminated 300 sandwiched between them. This allows the object to be laminated 300 to be transported from the upstream feeding unit 10 side to the downstream winding unit 20 side.
[0014] The first pressing section 30, the second pressing section 40, and the third pressing section 50 are arranged in this order from upstream to downstream between the upstream feeding section 10 and the downstream winding section 20. The first pressing section 30, the second pressing section 40, and the third pressing section 50 can press the laminated object 300 that is transported sandwiched between the transport films 71 and 72. The lamination device 1 may have as few as one pressing section, two, or four or more.
[0015] Each transport assist roller 60 consists of two rollers positioned above and below each other. One roller is located above the transport films 71 and 72, and the other roller is located below the transport films 71 and 72, gripping the transport films 71 and 72 from above and below. As the transport films 71 and 72 are transported, the two rollers rotate in conjunction with the transport. The transport assist rollers 60 are configured to be movable in the upward and downward directions.
[0016] The transport assist rollers 60 are positioned on the upstream and downstream sides of the first press section 30. They are also positioned on the upstream and downstream sides of the second press section 40 and the third press section 50. In the transport direction of the stacking object 300, the distance between the transport assist rollers 60 and the press section closest to them is narrower than the distance between adjacent transport assist rollers 60.
[0017] The first press section 30 includes a plurality of support columns 81 erected on the press table 80, an upper chamber 82 fixed to each support column 81, and a lower chamber 83 attached to each support column 81 so as to be vertically movable. The lower chamber 83 is connected to a lifting mechanism such as an air cylinder or a hydraulic cylinder via a joint, for example, and is vertically movable by the operation of the lifting mechanism.
[0018] Inside the upper chamber 82 and the lower chamber 83 are means for heating the stacked objects 300, such as heaters. In addition, the upper chamber 82 and / or the lower chamber 83 are connected to means for reducing the pressure in the space, such as a vacuum nozzle. As a result, when the upper chamber 82 and the lower chamber 83 are sealed, the vacuum nozzle can be used to evacuate the sealed space formed between the upper chamber 82 and the lower chamber 83, thereby reducing the pressure in the space.
[0019] The first pressing unit 30 positions the object to be laminated 300, which is transported from the feeding unit 10 sandwiched between transport films 71 and 72, between the upper chamber 82 and the lower chamber 83, and presses it. The first pressing unit 30 may have the function of heating and pressurizing in the upper chamber 82 and the lower chamber 83 to make the first film 320 and the second film 330 adhere tightly to the uneven surface of the base material 310 of the object to be laminated 300.
[0020] The second pressing unit 40 has the same structure as the first pressing unit 30. The second pressing unit 40 positions the laminate object 300 that is conveyed sandwiched between the conveyance films 71 and 72 from the first pressing unit 30 between the upper chamber 82 and the lower chamber 83, and presses it. The second pressing unit 40 may have a function of heating and pressurizing with the upper chamber 82 and the lower chamber 83 to substantially flatten the surface of the laminate object 300.
[0021] The third pressing unit 50 has the same structure as the first pressing unit 30. The third pressing unit 50 positions the laminate object 300 that is conveyed sandwiched between the conveyance films 71 and 72 from the second pressing unit 40 between the upper chamber 82 and the lower chamber 83, and presses it. The third pressing unit 50 may have a function of heating and pressurizing with the upper chamber 82 and the lower chamber 83 to further flatten the surface of the laminate object 300.
[0022] FIG. 2 is a schematic diagram illustrating the lamination method according to the present embodiment, and shows the operation of the first pressing unit 30 in chronological order for the lamination method of laminating a film on a base material. In the step shown in FIG. 2(a), the lower chamber 83 is in a lowered state, and a space is formed between the upper chamber 82 and the lower chamber 83. The space is empty. In the step shown in FIG. 2(a), there is a gap between the upper chamber 82 and the conveyance film 71, and there is also a gap between the lower chamber 83 and the conveyance film 72.
[0023] In the step shown in FIG. 2(b), the laminate object 300 sandwiched between the conveyance films 71 and 72 is conveyed into the space formed by the upper chamber 82 and the lower chamber 83. In the step shown in FIG. 2(b), there is a gap between the upper chamber 82 and the conveyance film 71, and there is also a gap between the lower chamber 83 and the conveyance film 72.
[0024] In the step shown in Figure 2(c), the relative distance between the upper chamber 82 and the lower chamber 83 is narrowed. That is, the object to be laminated 300, which is sandwiched between the transport films 71 and 72 and placed in the space formed by the upper chamber 82 and the lower chamber 83, is pressed between the upper chamber 82 and the lower chamber 83. Figure 2(c) shows an example where the upper chamber 82 is fixed and the lower chamber 83 rises, but the lower chamber 83 may be fixed and the upper chamber 82 may descend. Alternatively, the lower chamber 83 may rise and the upper chamber 82 may descend.
[0025] The steps shown in Figure 2(c) can be performed, for example, by evacuating the space formed between the upper chamber 82 and the lower chamber 83, thereby creating a reduced pressure state within the space. This suppresses the formation of voids between the substrate 310 and the first film 320, and / or between the substrate 310 and the second film 330. In Figure 2(c), the upper chamber 82 and the transport film 71 are in contact, and the lower chamber 83 and the transport film 72 are in contact.
[0026] In the step shown in Figure 2(d), the relative distance between the upper chamber 82 and the lower chamber 83 is increased. Figure 2(d) shows an example where the upper chamber 82 is fixed and the lower chamber 83 descends, but the lower chamber 83 may be fixed and the upper chamber 82 may rise. Alternatively, the lower chamber 83 may descend and the upper chamber 82 may rise.
[0027] In Figure 2(d), there is a gap between the lower chamber 83 and the transport film 72, but the upper chamber 82 and the transport film 71 are in contact. In the state shown in Figure 2(d), the upper chamber 82 and the transport film 71 may stick together, making it impossible to transport the object to be laminated 300 toward the second press section 40.
[0028] In the steps shown in Figures 2(e) to 2(g), the transport films 71 and 72 are moved upward or downward to create gaps between the upper chamber 82 and the transport film 71, and between the lower chamber 83 and the transport film 72. In Figure 2(d), the upper chamber 82 and the transport film 71 are stuck together, so here the transport films 71 and 72 are moved downward.
[0029] Specifically, the transport assist rollers 60 located on both sides of the first press section 30 are moved downward. This allows the transport film 71 to be peeled away from the upper chamber 82, as shown in Figure 2(f), even if the upper chamber 82 and the transport film 71 are stuck together in the state shown in Figure 2(d). When the transport assist rollers 60 are moved downward, if the transport film 71 can be peeled away from the upper chamber 82, it is not necessary to lower the lower chamber 83 until the transport film 72 is in contact with the lower chamber 83 in Figure 2(f).
[0030] If the lower chamber 83 and the transport film 72 are stuck together, the transport film 72 can be peeled away from the lower chamber 83 by moving the transport films 71 and 72 upward. It is preferable to start the steps shown in Figure 2(d) and Figure 2(e) simultaneously. This allows for a reduction in cycle time.
[0031] In the step shown in Figure 2(g), the transport assist rollers 60 located on both sides of the first press section 30 are moved upward so that there is a gap between the upper chamber 82 and the transport film 71, and a gap between the lower chamber 83 and the transport film 72. In this state, the object to be laminated 300, sandwiched between the transport films 71 and 72, can be transported toward the next stage, the second press section 40.
[0032] Note that if, as shown in Figure 2(f), there is already a gap between the upper chamber 82 and the transport film 71, and also a gap between the lower chamber 83 and the transport film 72, then the step in Figure 2(g) is unnecessary.
[0033] The above describes the first pressing section 30, but in the second pressing section 40 and the third pressing section 50 as well, there are cases where the upper chamber 82 and the transport film 71 or the lower chamber 83 and the transport film 72 stick together after the object to be laminated 300 has been pressed. Transport assist rollers 60 are also provided on both sides of the second pressing section 40 and the third pressing section 50, and similar to the first pressing section 30, the sticking can be released by moving the transport assist rollers 60 vertically after the object to be laminated 300 has been pressed.
[0034] Figure 3 illustrates the drive of the transport assist roller. The transport films 71 and 72 are sandwiched between the transport assist roller 60, and a drive unit 90 is connected to the transport assist roller 60. The drive unit 90 can move the transport assist roller 60 upward and downward. The drive unit 90 is, for example, an air cylinder. The drive unit 90 may also be a hydraulic cylinder or a servo motor.
[0035] In Figures 3(a), 3(b), and 3(c), the drive unit 90 is fixed and its position does not change. In contrast, the transport assist roller 60 is driven by the drive unit 90 and can move upward and downward. The transport assist roller 60 and the drive unit 90 are typical examples of the moving mechanism according to the present invention. The moving mechanism according to the present invention is capable of moving two transport films upward and downward.
[0036] In Figures 2(a) to 2(d) and 2(g), for example, the transport assist roller 60 is in the position shown in Figure 3(b). In Figure 2(f), for example, the transport assist roller 60 is in the position shown in Figure 3(a). In Figure 3(a), the transport assist roller 60 is descending relative to Figure 3(b).
[0037] In Figure 3(c), the transport assist roller 60 is raised compared to Figure 3(b). For example, in Figure 2(d), the lower chamber 83 and the transport film 72 may stick together, making it impossible to transport the object to be laminated 300 toward the second press section 40. In that case, the sticking can be released by raising the transport assist roller 60 as shown in Figure 3(c), as shown in Figure 2(f).
[0038] As described above, the lamination apparatus according to the present invention has a moving mechanism positioned upstream and downstream of the press section, which is capable of moving the two transport films upward and downward. This allows gaps to be created between the upper chamber and the transport films, and between the lower chamber and the transport films, even if the transport films stick to the upper or lower chamber, by moving the two transport films upward or downward. As a result, transport abnormalities caused by the transport films sticking together can be suppressed.
[0039] Furthermore, since the moving mechanism can be constructed simply by adding a drive unit to the transport assist rollers that the stacking device originally has, the moving mechanism can be realized with only a slight increase in cost without increasing the size of the stacking device.
[0040] Although preferred embodiments have been described in detail above, the invention is not limited to the embodiments described above, and various modifications and substitutions can be made to the embodiments described above without departing from the scope of the claims.
