Summary of the Invention
Problems to be Solved by the Invention
[0004] However, when the sheet-shaped flexible substrate material is non-conductive, depending on the properties of the material, strong static electricity may be generated, resulting in taking out two or more sheets at a time.
[0005] Therefore, at least one aspect of the problems of the present disclosure is to provide a sheet-shaped non-conductive flexible substrate material conveying device, a sheet-shaped non-conductive flexible substrate material conveying method, a sheet-shaped non-conductive flexible substrate material stack, and an anti-adhesion insertion non-conductive sheet that can reliably take out sheet-shaped non-conductive flexible substrate materials one by one. It should be noted that for those skilled in the art who can read from the embodiments and their descriptions characteristic of the present disclosure described in the specification, drawings, etc. of the present disclosure, the problems that are obvious to them may also become the problems to be solved by the divided inventions when a divisional application is filed based on the present disclosure.
Means for Solving the Problem
[0006] In order to achieve the above object, the sheet-shaped non-conductive flexible substrate material conveying device of the present disclosure is a sheet-shaped non-conductive flexible substrate material conveying device including a sheet conveying unit, a static elimination ion generation unit, and a storage unit. In the storage unit, a plurality of sheet-shaped non-conductive flexible substrate materials and insertion non-conductive sheets are alternately stacked in a single-sheet manner and stored. The sheet conveying unit includes a holding unit that holds the upper surfaces of the sheet-shaped non-conductive flexible substrate material and the insertion non-conductive sheet. The insertion non-conductive sheet has a concave portion or a convex portion formed on at least one side surface facing the static elimination ion generation unit, or a plurality of through holes penetrating the plane of the insertion non-conductive sheet are formed. After the static elimination ion generation unit sprays a static elimination ion-containing gas toward the sheet-shaped non-conductive flexible substrate material or the insertion non-conductive sheet disposed on the upper surface of the storage unit for static elimination, the sheet conveying unit conveys the statically eliminated sheet-shaped non-conductive flexible substrate material or the insertion non-conductive sheet.
[0007] Further, the method for transporting a sheet-shaped non-conductive flexible substrate material according to the present disclosure uses a sheet-shaped non-conductive flexible substrate transport device including a sheet transport unit, a static elimination ion generation unit, and a storage unit, and a plurality of sheet-shaped non-conductive flexible substrate materials and an inserted non-conductive sheet that are alternately stacked and stored in a single-sheet manner, and is a method for transporting a sheet-shaped non-conductive flexible substrate material taken out from the storage unit. The sheet transport unit includes a holding unit that holds the upper surfaces of the sheet-shaped non-conductive flexible substrate material and the inserted non-conductive sheet. The inserted non-conductive sheet has a concave portion or a convex portion formed on at least one side surface facing the static elimination ion generation unit, or a through hole penetrating the inserted non-conductive sheet. When the inserted non-conductive sheet is disposed on the upper surface of the storage unit, a first static elimination step in which the static elimination ion generation unit blows a static elimination ion-containing gas upward, and an inserted non-conductive sheet taking-out step in which the sheet transport unit holds and takes out the inserted non-conductive sheet deionized by the static elimination ion-containing gas are performed. When the sheet-shaped non-conductive flexible substrate material is disposed on the upper surface of the storage unit, a sheet-shaped non-conductive flexible substrate material lifting step in which the sheet transport unit lifts one side surface side of the sheet-shaped non-conductive flexible substrate material facing the static elimination ion generation unit, a second static elimination step in which the static elimination ion generation unit blows a static elimination ion-containing gas between the sheet-shaped non-conductive flexible substrate material lifted by the sheet transport unit and the inserted non-conductive sheet disposed thereunder, and a sheet-shaped non-conductive flexible substrate material transport step in which the sheet transport unit transports the deionized sheet-shaped non-conductive flexible substrate material are performed.
[0008] Further, in the stack of sheet-shaped non-conductive flexible substrate materials according to the present disclosure, a plurality of sheet-shaped non-conductive flexible substrate materials and an inserted non-conductive sheet are alternately stacked and packaged in a single-sheet manner. The inserted non-conductive sheet has a concave portion or a convex portion formed on at least one side surface, or a plurality of through holes penetrating the plane of the inserted non-conductive sheet.
[0009] In addition, for a stack of sheet-like non-conductive flexible substrate materials of the present disclosure that are stacked in single sheets and packaged, an anti-adhesion insertion non-conductive sheet is inserted one by one between the plurality of sheet-like non-conductive flexible substrate materials. At least one side surface of the insertion non-conductive sheet is formed with a concave portion or a convex portion, or a plurality of through holes penetrating the plane of the insertion non-conductive sheet are formed.

Modes for Carrying Out the Invention
[0012] The sheet-shaped non-conductive flexible substrate material conveying device 100 of the present disclosure (hereinafter referred to as the conveying device 100) can be incorporated inside as a substrate conveying unit of various manufacturing devices using a sheet-shaped non-conductive flexible substrate as a material. Specifically, it is preferably used as a conveying unit of a printing device that forms metal wiring on a sheet-shaped non-conductive flexible substrate. Hereinafter, the conveying device 100 as a conveying unit of a printing device that forms metal wiring on the above-mentioned sheet-shaped non-conductive flexible substrate and manufactures an electric circuit or an electronic circuit will be described as an example. However, the embodiments described in the present disclosure are presented only as examples and do not limit the entire protection scope of the disclosed technology.
[0013] FIG. 1 is a schematic diagram showing the overall configuration of the conveying device 100. The conveying device 100 includes at least a sheet conveying unit 110, a static elimination ion generation unit 120, a plurality of sheet-shaped non-conductive flexible substrate materials P, and a storage unit 130 in which a substrate material stack in which the insertion non-conductive sheets S are alternately stacked in a single-sheet form is stored. Further, a printing device (not shown) or another processing device that processes the substrate material is arranged at the conveyance destination of the sheet-shaped non-conductive flexible substrate material P conveyed by the conveying device 100. The conveying device 100 is for taking out a plurality of sheet-shaped non-conductive flexible substrate materials P and the insertion non-conductive sheets S one by one from the storage unit 130 and conveying them to the conveyance destination. Also, it also has a function of eliminating static electricity so that no trouble occurs due to static electricity at the conveyance destination.
[0014] The sheet conveying unit 110 may be an automatic conveying unit which is a machine called, for example, a robot arm, a handler, etc., and includes a holding unit 111. The holding unit 111 can hold the sheet-shaped non-conductive flexible substrate material P and the inserted non-conductive sheet S by contacting only the upper surfaces thereof. Specifically, it is equipped with a vacuum pad (suction cup) in the center, such as a vacuum suction pad or a suction cup gripper, and by evacuating the air in the suction cup with a vacuum pump, a suction force due to vacuum is generated to hold the sheet, and the sheet can be released by releasing the vacuum. Since it is difficult to damage the surface of the object, it is suitable for handling flexible sheet objects.
[0015] The driving direction and mechanism of the sheet conveying unit 110 are not limited to specific ones, and it may be configured to be movable in the XYZ directions as shown, such as a lifting mechanism and a conveying mechanism (not shown). Thus, by the operations described later, the sheets can be picked up and held one by one and conveyed to the conveying destination. For example, the conveying destination may be a printing apparatus, or a stage or a workpiece receiving portion of other manufacturing apparatuses, and the sheet can be placed thereon with the plane facing up.
[0016] The static elimination ion generation unit 120 may be, for example, a corona discharge type equipped with a blower fan, a discharge electrode, etc., and has a function of ionizing the molecules in the air by high-voltage discharge and blowing the ion-containing air. When these ion-containing air is blown onto the sheet charged with polarization to any one of the polarities in the substrate material stack, the static electricity is neutralized and the static elimination is achieved. The static elimination ion generation unit 120 may be, for example, a so-called bar type ionizer having a blowing unit along the width direction of the sheet, and can be installed with the blowing direction facing the uppermost surface of the substrate material stack.
[0017] The storage unit 130 is for holding and storing a stack of substrate materials in which a sheet-like non-conductive flexible substrate material P and an inserted non-conductive sheet S are laminated. Specifically, it may have a structure like a box with an open top surface, or a structure like columns in which frames for holding the four corners stand upright in the vertical direction (Z direction). In this figure, as an example, the latter structure is shown, and it is indicated by a dotted line representation that it does not block the arrival of ion-containing air blown from the static elimination ion generation unit 120. Also, the lower part of the storage unit 130 may have a lifting mechanism that raises the stack of substrate materials so as to lift it as the number of sheets taken out gradually decreases.
[0018] Suitable materials for constituting the sheet-like non-conductive flexible substrate material P are, for example, polymers and high molecular compounds such as polyimide (PI), polyethylene terephthalate (PET), and polyethylene naphthalate (PEN). In addition, non-conductive and dielectric materials such as paper, or cellulose nanofiber (CNF), polylactic acid (PLA) bioplastic films, etc., which are materials that make it difficult to take out one by one in a sheet form due to the generation of static electricity, may be included. Although a wiring pattern made of metal is formed on such a sheet-like non-conductive flexible substrate material P and it is mainly used as a part of an electric circuit or an electronic circuit, it may be used for other purposes. As a numerical example of the thickness for reference, it may be 200 μm or less (excluding 0 μm).
[0019] Here, the descriptions of "non-conductor", "sheet", and "flexible" in the present disclosure may be interpreted as follows. "Non-conductor" may be understood as intended to exclude conductors such as metals, and may include insulators, dielectrics, and non-conductors. "Sheet" refers to an object with a thin and wide surface having a certain width, cut to an appropriate length to be in a sheet form, which may be rectangular and generally has a two-dimensional shape. Regarding its thickness, those skilled in the art can select variously according to the application. "Flexible" is interpreted to the extent of being flexible, having no great resistance to bending or compression, being able to be easily bent, and being able to maintain durability and functions during that time.
[0020] When processing such a sheet-shaped non-conductor flexible substrate material P into a sheet form, in the storage unit 130, it is assumed to be stored in a stacked state as a substrate material stack, and one sheet is taken out from the top surface one by one by the sheet conveyance unit 110 and conveyed.
[0021] However, in a state where such sheet-shaped non-conductor flexible substrate materials P are laminated and overlapped in a sheet form, they are easily charged with static electricity due to friction, and there is a problem that when peeling them off, a strong resistance occurs due to the electrostatic force that causes the charged substrates to attract each other, and even when trying to take out one by one, a plurality of sheets may be taken out together.
[0022] On the other hand, as in the above Patent Document 1, means such as rocking, bending, and various mechanical or physical taking-out means are known, but depending on the characteristics of the material itself, such as dielectric constant, viscosity, adhesiveness, and surface structure, there may be a case where the electrostatic force is so strong that it cannot be peeled off by simply applying force. In such a case, it is preferable to solve the problem by an electrostatic removal approach in order not to damage the substrate.
[0023] Specifically, in order to prevent adhesion between substrates, when forming a material stack by laminating a plurality of sheet-like non-conductive flexible substrate materials P in a sheet-by-sheet manner, an insertion non-conductive sheet S is inserted one by one between two sheet-like non-conductive flexible substrate materials P.
[0024] The insertion non-conductive sheet S is a sheet having dimensions of length and width generally similar to those of the sheet-like non-conductive flexible substrate material P. For example, it can be composed of a polymer resin such as polycarbonate (PC), polyethylene terephthalate (PET), polypropylene (PP), or a resin material containing these. Also, considering the use of being transported in a clean room, any material with less dust generation is acceptable, and it can also be a clean paper or dust-free paper with a thickness above a certain level. As a numerical example of the thickness for reference, it may be thicker than the sheet-like non-conductive flexible substrate material P and be 2 mm or less (excluding 0 mm).
[0025] Further, the surface of the insertion non-conductive sheet S may have fine irregularities formed thereon. For example, regarding its surface properties, depending on the thickness of the sheet itself, surface treatment such as matte treatment, satin finish treatment, sandblasting treatment, or etching treatment may be performed so that the arithmetic mean roughness Ra is 1 μm to 1 mm. This can produce an effect of reducing adhesion with the sheet-like non-conductive flexible substrate material P.
[0026] The resistivity of the insertion non-conductive sheet S may generally be a material having a resistivity of 10 5 Ω·m or more, as expected from the term "non-conductive". Also, if the resistivity is too high, the anti-adhesion function will weaken, so it may also be a material with a resistivity of 10 10 Ω·m or less. This can produce an effect of reducing adhesion with the sheet-like non-conductive flexible substrate material P.
[0027] Such an inserted non-conductive sheet S is inserted one by one between sheet-shaped non-conductive flexible substrate materials in a stack of sheet-shaped non-conductive flexible substrate materials P that are stacked and packaged in a sheet-like manner in a laminated form.
[0028] FIG. 2 is a top view of the inserted non-conductive sheet S of the present disclosure. The inserted non-conductive sheet S may have recesses or protrusions formed on at least one side surface, or a plurality of through-holes penetrating the plane of the inserted non-conductive sheet may be formed.
[0029] As shown in FIG. 2, the inserted non-conductive sheet S of the present disclosure has irregularities recognized as recesses CC or protrusions CV on the end surfaces in the left-right direction (X direction) of the paper surface. Further, it has openings formed by a plurality of through-holes H. The effects of these recesses CC or protrusions CV, or the through-holes H, and the static elimination ion generation unit 120 will be described later.
[0030] The recesses CC and protrusions CV in FIG. 2 can be defined as follows. The recess CC can be recognized as a notch with respect to the first front end surface SFL1 or the first rear end surface SBL1 in the left-right direction (X direction) of the paper surface. Conversely, the protrusion CV can be recognized as a protruding portion with respect to the second front end surface SFL2 or the first rear end surface SBL2. Although details will be described later, when the recess CC or protrusion CV is provided on one side surface that confronts the static elimination ion generation unit 120, it facilitates the intrusion of ion-containing air released from the static elimination ion generation unit 120.
[0031] Further, since the protrusion CV is a peninsula-shaped portion provided on the front side or the rear side, which are part of the outer peripheral portions of the four sides of the inserted non-conductive sheet S, it can also be used as a non-opening portion that can be picked up and held by the holding portion 111 of the sheet conveyance unit 110. Specifically, for example, the holding portion 111, which is an adsorption pad, can adsorb the region of the protrusion CV to hold and lift the inserted non-conductive sheet.
[0032] The plurality of through holes H are openings penetrating in the front-rear direction (Z direction) of the paper surface. In the illustrated example, the shape of the opening is circular, but it is not limited thereto and may be openings of various shapes. By providing the plurality of through holes H, it facilitates the intrusion of ion-containing air discharged from the static elimination ion generation unit 120. There are also effects of not increasing the rigidity of the insertion non-conductive sheet S too much and being able to reduce the weight of the insertion non-conductive sheet S itself.
[0033] From the viewpoint of preventing adhesion, it is preferable that the aperture ratio of the insertion non-conductive sheet S by the plurality of through holes H, that is, the ratio of the total area of all the through holes H to the entire area of the insertion non-conductive sheet S, is 25 to 75%.
[0034] The insertion non-conductive sheet S preferably has a higher bending rigidity than the sheet-like non-conductive flexible substrate material P. The bending rigidity in the present disclosure represents the ability of a material to resist a bending load and the degree of resistance to bending, and can be quantitatively compared, for example, by the following method. The following test method is merely an example.
[0035] (Test method) 1. Prepare a test piece with the dimensions actually used. 2. Fix one end and perform a bending test with a predetermined force (which may be gravity) applied in a state where the other end is open. 3. Measure the amount of deflection (change amount) by the bending test. 4. Assume that the material with a smaller value of the amount of deflection (change amount) has a higher bending rigidity.
[0036] The bending rigidity also depends on the thickness of the material. Therefore, the condition that the bending rigidity of the insertion non-conductive sheet S is higher than that of the sheet-like non-conductive flexible substrate material P can be satisfied, for example, by making the insertion non-conductive sheet S thicker than the sheet-like non-conductive flexible substrate material P and making the bending strength or bending elastic modulus of the insertion non-conductive sheet S higher than that of the sheet-like non-conductive flexible substrate material P. Note that the measurement methods for the bending strength and bending elastic modulus are defined in JIS K 7171.
[0037] As will be described later, by making the bending rigidity of the inserted non-conductive sheet S higher than that of the sheet-shaped non-conductive flexible substrate material P, when the sheet-shaped non-conductive flexible substrate material P is exposed on the top surface of the substrate material stack, there is an effect of reliably taking out the sheet-shaped non-conductive flexible substrate materials one by one.
[0038] Further, if the inserted non-conductive sheet S is too thick, the number of sheet-shaped non-conductive flexible substrate materials P that can be stacked will decrease. Therefore, the thickness of the inserted non-conductive sheet S is preferably 10 times or less and 1 time or more the thickness of the sheet-shaped non-conductive flexible substrate material P.
[0039] FIG. 3 is a diagram showing the pickup position of the sheet. In this figure, the outline of the inserted non-conductive sheet S is shown by a dotted line, and the sheet-shaped non-conductive flexible substrate material P is shown by a solid line. Also, it is shown in a top view of the state where the inserted non-conductive sheet S and the sheet-shaped non-conductive flexible substrate material P are overlapped, and the outer dimensions in the overlapped state are the same.
[0040] In FIG. 3, basically no openings or the like are formed in the sheet-shaped non-conductive flexible substrate material P at this stage, and the entire sheet is a non-opening part. And, so that it can be recognized in a top view, no through holes H or recesses CC are formed in the outer peripheral part of the inserted non-conductive sheet S, and it is a non-opening part. Then, by a plurality of holding parts 111 arranged to move up and down from above at the illustrated positions, pickup is possible in any case of the inserted non-conductive sheet S and the sheet-shaped non-conductive flexible substrate material P. That is, there is no need to change the pickup position depending on the inserted non-conductive sheet S and the sheet-shaped non-conductive flexible substrate material P taken out alternately, and efficient extraction is possible.
[0041] Regarding the pickup position defined by the arrangement of the holding parts 111, for convenience of holding a rectangular sheet, it is preferable to hold at least the four corners as shown in the figure.
[0042] Also, even when the sheet conveying unit 110 is raising the sheet while holding it or holding it in the air, the sheet may flutter due to the wind of the ion-containing air blown from the static elimination ion generation unit 120. In order to hold it more firmly, as shown in the figure, at the front end and the rear end, respectively, it may be held at three or more positions along a direction perpendicular to the air blowing direction.
[0043] Next, a method for transporting a sheet-shaped non-conductive flexible substrate material using the sheet-shaped non-conductive flexible substrate material transporting apparatus of the present disclosure will be described with reference to the drawings and flowcharts. FIG. 4 is a flowchart showing the flow of processing of the method for transporting a sheet-shaped non-conductive flexible substrate material of the present disclosure, and FIG. 5 is a diagram showing static elimination when an insertion non-conductive sheet is disposed on the upper surface.
[0044] First, a case where an insertion non-conductive sheet S is disposed on the upper surface of the storage unit 130 will be described. In step S101, the static elimination ion generation unit 120 blows a static elimination ion-containing gas toward the upper surface of the storage unit 130 (first static elimination step). As a result, the ion-containing air enters from the concave portion CC and the through hole H, and by being statically eliminated, the electrostatic adhesion between the insertion non-conductive sheet S and the sheet-shaped non-conductive flexible substrate material P is significantly reduced.
[0045] Next, in step S102, the sheet conveying unit 110 holds and takes out the insertion non-conductive sheet S that has been statically eliminated by the static elimination ion-containing gas (insertion non-conductive sheet taking-out step). The taken-out insertion non-conductive sheet S is conveyed to a location different from the conveyance destination of the sheet-shaped non-conductive flexible substrate material P and stored together. The insertion non-conductive sheet S may be reused thereafter.
[0046] As a result, the sheet-shaped non-conductive flexible substrate material P is disposed on the upper surface of the storage unit 130.
[0047] Instead, FIG. 6 shows a diagram of static elimination when a sheet-shaped non-conductive flexible substrate material is disposed on the upper surface. In this case, in step S103, the sheet conveyance unit 110 lifts the side surface of the sheet-shaped non-conductive flexible substrate material P facing the static elimination ion generation unit 120 (sheet-shaped non-conductive flexible substrate material lifting step).
[0048] In this case, since the concave portions CC and the through holes H are formed in the inserted non-conductive sheet S, the contact area is reduced, and the sticking due to static electricity is reduced to some extent. At the front end portion, it can be partially lifted by the holding portion 111.
[0049] Also, as described above, when the bending rigidity of the inserted non-conductive sheet S is greater than the bending rigidity of the sheet-shaped non-conductive flexible substrate material P, when the holding portion 111 partially lifts the sheet-shaped non-conductive flexible substrate material P, a certain amount of resistance force is generated, the adhesion is released, and it can stay in place. Thereby, the sheet-shaped non-conductive flexible substrate materials P can be more reliably taken out one by one.
[0050] Next, in step S104, the static elimination ion generation unit 120 blows a static elimination ion-containing gas between the sheet-shaped non-conductive flexible substrate material P lifted by the sheet conveyance unit 110 and the inserted non-conductive sheet S disposed thereunder (second static elimination step). If a part of the end portion of the sheet-shaped non-conductive flexible substrate material P can be lifted, the ion-containing air can enter from the gap between the sheet-shaped non-conductive flexible substrate material P and the inserted non-conductive sheet S, and static elimination can be performed.
[0051] Then, the sheet conveyance unit 110 conveys the static-eliminated sheet-shaped non-conductive flexible substrate material P (sheet-shaped non-conductive flexible substrate material conveyance step).
[0052] As described above, the sheet-shaped non-conductive flexible substrate materials can be reliably taken out one by one. In the method for transporting the sheet-shaped non-conductive flexible substrate material of the present disclosure, basically, steps S101 to S105 are repeated.
[0053] For reference, the processing steps for the sheet-shaped non-conductive flexible substrate material after being transported are described. For the transported sheet-shaped non-conductive flexible substrate material, an ink composition containing metal nanoink is printed on its surface by a printing device to form a wiring pattern. Further, using the wiring pattern as a base, metal buildup for further wiring is performed by electroless plating or the like to complete the conductive path of the wiring pattern.
[0054] (Modification example) FIG. 7 is a diagram showing a modification example of the inserted non-conductive sheet of the present disclosure. In this example, assuming that the left side of the paper surface is the front side and the right side of the paper surface is the rear side, through holes H are formed so that the aperture ratio is different between the front side and the rear side. In this way, the distribution of the aperture ratio may be set to be different within the same sheet.
[0055] In the example of FIG. 7, the front region on the left side of the paper surface is a low aperture ratio region LR, and the rear region on the right side of the paper surface is a high aperture ratio region HR. In this case, even if ion-containing air is blown from the front side, the aperture ratio increases, so that the charge removal effect on the rear side can be enhanced.
[0056] (Modification example of the embodiment) The sheet-shaped non-conductive flexible substrate material stack and the inserted non-conductive sheet for preventing adhesion, which are used in the sheet-shaped non-conductive flexible substrate material transport device and the sheet-shaped non-conductive flexible substrate material transport method of the present disclosure, can also be packaged and sold as products as single entities. Here, the packaging is not limited to being physically packaged, and may be interpreted as meaning that the products are grouped together.

The embodiments shown in the present disclosure and their modified forms are also included in the scope and gist of the present disclosure, and are treated as technologies to be protected in the claims, those equivalent thereto, and those equal thereto.
