Description

  The present invention relates to a wooden member, a casing, and a manufacturing method thereof.

  In recent years, from the viewpoint of reducing environmental impact and / or decorativeness, examples of applying naturally-derived wooden materials to various industrial products such as housings of electronic devices have been found. When wooden materials are used for electronic device casings, etc., nodes and defects (worm erosion, corrosion, etc.) are typically taken into account in terms of decorativeness based on wood grain and workability such that cracks or cracks are less likely to occur. ) Etc. are selected and used. Or, as a decorative layer exposed on the surface, a single-plate member with excellent appearance without a node is used, and for an internal structure layer not exposed on the surface, a member having a node, a thinning material, a laminated material, etc. Inexpensive members are used.

  A housing of an electronic device or the like generally has a three-dimensional shape. Therefore, it may be required to process a wooden part into a three-dimensional shape for the purpose of making more parts into a wood grain and enhancing the beauty. In particular, it is desirable that the wooden member be processed into a tray shape having a generally rectangular frame at the periphery of the top plate in order to suppress warping due to moisture absorption. In order to manufacture a wooden member having such a three-dimensional shape at low cost and with high productivity, development of a press forming technique for the wooden member has been advanced.

  FIG. 1 is a sectional view showing a typical method for manufacturing a wooden member having a tray shape. First, as shown in FIG. 1 (a), a temporary stacked plywood 30 in which several layers of wooden boards (or wooden plywood) 31 and 33 are laminated via an adhesive 35 so as to form a desired thickness is formed by water vapor. 40 is softened. The softened temporary stacking plywood 30 is inserted between the female mold 51 and the male mold 52 as shown in FIG. 1 (b), and then the wooden stack as shown in FIG. 1 (c). Press-molded into member 10. Thereafter, the press dies 51 and 52 are released, and the tray-shaped wooden member 10 as shown in FIG. 2 is taken out. Note that FIG. 2 shows a top view and two side views of the wooden member 10 when the top plate portion 11 serving as an exterior surface of a housing or the like is viewed upward.

  In the conventional press molding technique, as shown in FIG. 2, cracks or cracks 17 may occur in the bent portion of the tray-shaped wooden member 10, particularly in the corner portion as shown in the figure, and the processing yield of the wooden member Can be reduced. Large bending and deep drawing may be required to improve the design and flexibility of the housing and / or to increase the internal volume of the electronic device. Is increased, and the generation of cracks or cracks 17 is promoted. In particular, when thinned wood or the like having knots that are difficult to process is used for the internal structure layer of the housing, cracks and wrinkles are likely to occur when the knots are located at the bent portions. In addition, flame retardants are sometimes required for the casings of electronic devices. In such cases, wooden members are generally impregnated with flame retardants. However, the use of flame retardants can cure wooden members. , Tends to cause cracks and the like.

  In addition, when the aperture is deep, the surplus portion of the wooden board such as the wooden plywood 30 is folded, but the folding part 15 can initially retain the press shape, but gradually rises depending on the use environment conditions. There is. Further, the position at which the folded portion 15 is generated can be changed according to the set state of the wooden board in the press mold, the position of the node included in the wooden board, and the like, so that it is difficult to specify. For example, when the folding part 15 is generated in the corner part, the risk of turning up may be further increased. In addition, the fact that the position of the folding portion is not constant can be a factor that reduces the aesthetic processing yield of the casing of the electronic device.

  Furthermore, in the formation of wooden materials, there is a difference in the probability of occurrence of defects such as cracks depending on the type of wood used and the quality of the raw materials, and it is difficult to stably process with a yield above a certain level.

  Hereinafter, embodiments will be described in detail with reference to the drawings. In the drawings, various components are not necessarily drawn to the same scale. Throughout the drawings, the same or corresponding components are denoted by the same or similar reference numerals.

(First embodiment)
With reference to FIG. 3, the manufacturing method of the wooden member which concerns on 1st Embodiment is demonstrated. First, a homogeneous resin sheet 120 as shown in the top view of FIG. The resin sheet 120 has a smooth surface. The resin sheet 120 may also have a certain level of strength and stretchability, and be resistant to temperatures (for example, about 150 °) in a subsequent pressing step. For example, a sheet formed of a resin such as polyethylene terephthalate (PET), polyethylene (PE), or polyimide (PI) can be used. Although the adhesiveness of the resin sheet 120 is not necessarily required, a material having adhesiveness on one side such as a polyimide tape such as a Kapton (registered trademark) tape can be used. However, the adhesive is preferably not transferred to wood. In one example, the resin sheet 120 may have elasticity and heat shrinkability. The thickness of the resin sheet 120 is not particularly limited as long as a certain level of strength and workability are obtained, and may be within a range of 5 μm to 300 μm, for example.

  Further, as shown in the cross-sectional view of FIG. 3B, the wooden board 130 to be processed is softened in, for example, water vapor 140. The wooden board 130 has one or more wooden board materials. For example, the wooden board 130 may be a wooden plywood in which a plurality of board materials 131 and 133 are temporarily stacked via an adhesive 135 such as a corn starch thermosetting adhesive so as to form a desired thickness. In addition, as the decorative layer 131 exposed as an exterior surface, a plate material without a node is used as a single plate, and as the internal structure layer 133 not exposed on the surface, a member having a node, a thinned material, or a laminated material is inexpensive. A member may be used. Each of the decorative layer 131 and the internal structure layer 133 may include several layers of plate materials. The thickness of each plate material can be, for example, about 200 μm-500 μm. The time required for softening by the water vapor 140 is, for example, about 30 seconds.

  Next, as shown in the cross-sectional view of FIG. 3C, the resin sheet 120 and the wooden board 130 are overlapped and disposed between the female mold 151 and the male mold 152. The molds 151 and 152 are manufactured so as to obtain a wooden member having a desired three-dimensional shape having a bent portion, for example, a tray shape. When the obtained wooden member is used for a housing such as an electronic device, typically, the exterior surface of the wooden member has a convex shape. Therefore, when the board | plate material 131 is a decorative layer among several board | plate materials of the wooden board 130, the wooden board 130 is arrange | positioned so that the decorative layer 131 may be located in the female type | mold die 151 side. The resin sheet 120 is disposed between the female mold 151 and the wooden board 130. In addition, when the resin sheet 120 is adhesive on one side, such as Kapton (registered trademark) tape, the resin sheet 120 is placed on the wooden board 130 (decorative layer 131) prior to disposition between the molds. It may be pasted.

  Next, as shown in FIG. 3 (d), the wooden plate 130 is press-molded together with the resin sheet 120 using the molds 151 and 152 to form the wooden member 100. The pressing conditions may depend on the wood type and / or thickness of the wooden board 130. For example, in the press molding of the wooden plate 130 having a total thickness of several mm, the mold temperature can be set to 100 ° C. to 150 ° C., the molding pressure can be set to about 9 MPa, and the pressing time can be set to about 5 minutes. The temperature of the mold 151 may be different from the temperature of the mold 152.

  Then, the press dies 151 and 152 are released, and the resin sheet 120 is peeled, whereby the wooden member 100 as shown in FIG. 4 is taken out. FIG. 4 shows a top view and two side views of the wooden member 100 when the top plate 101 serving as an exterior surface of a housing or the like is viewed upward. In the illustrated example, the wooden member 100 has a tray shape.

  The wooden member 100 has a folded portion 105 in which a surplus portion of the wooden board 130 is folded at a bent portion according to the magnitude of bending and the depth of drawing. However, in the wooden member 100, generation | occurrence | production of the defect like the crack or the crack 17 shown in FIG. 2 is suppressed or prevented. Cracks and the like are particularly likely to occur at corners where stress is concentrated due to the catch between the wooden plate and the mold due to irregularities such as annual rings. However, according to the method shown in FIG. 3, the smooth surface of the resin sheet 120 prevents the mold from being caught and / or the resin sheet 120 relieves stress, thereby suppressing the occurrence of cracks and the like. It is.

  Therefore, the manufacturing yield of the wooden member 100 can be improved, and the manufacturing cost of the wooden member 100 can be reduced. In addition, processing restrictions such as bending and drawing are eased, and the degree of freedom in designing the wooden member can be increased. This also means that the internal volume of the electronic device can be increased when the wooden member 130 is used in the housing of the electronic device. Furthermore, since the same effect is acquired when using the wooden board hardened | cured by the impregnation of the flame retardant, it becomes easy to satisfy | fill the flame retardance request | requirement of an electronic device housing | casing.

  In addition, when a resin sheet 120 having elasticity and heat shrinkability is used, it is possible to suppress unevenness such as an annual ring of the wood from being flattened by pressing, and to obtain a wooden member having a tactile sensation peculiar to wood. be able to.

  The wooden member 100 shown in FIG. 4 can be used as a casing of an electronic device such as a desktop or notebook PC, a portable information terminal, or a mobile phone through a predetermined process such as cutting. Similarly, the wooden member 100 may be used for various industrial products.

(Second Embodiment)
With reference to FIG. 5, the manufacturing method of the wooden member which concerns on 2nd Embodiment is demonstrated. First, a resin sheet 220 as shown in the top view of FIG. The resin sheet 220 has an adhesive 222 formed in a predetermined pattern on a homogeneous resin film 221. For example, the resin film 221 may be the same as the resin sheet 120 described in relation to the first embodiment. The adhesive 222 preferably has thermoplasticity and thermosetting property, and has higher adhesion to wood than the resin film 221. For example, a corn starch adhesive (such as H298 manufactured by NSC Japan) can be used. Also, thermosetting adhesives such as melamine, phenol and epoxy may be used. The adhesive 222 is harder than the resin film 221 and forms a hard portion of a predetermined pattern on the resin sheet 220 to determine the starting point of the folded portion of the wooden board.

  Further, as shown in the cross-sectional view of FIG. 5B, the wooden board 230 to be processed is softened in, for example, water vapor 140. The wooden board 230 has one or more wooden boards, and may have the same configuration as the wooden board 130 described in relation to the first embodiment, for example. As an example, the wooden board 230 includes a decorative layer 231 and an internal structure layer 233 temporarily stacked via an adhesive 235 such as a corn starch thermosetting adhesive.

  Next, as shown in the sectional view of FIG. 5C, the resin sheet 220 and the wooden plate 230 are overlapped and disposed between the female mold 151 and the male mold 152. The wooden board 230 is disposed so that the decorative layer 231 is positioned on the female mold 151 side. The resin sheet 220 is disposed between the female mold 151 and the wooden plate 230 with the surface on which the adhesive 222 is formed facing the wooden plate 230.

  Next, as shown in the cross-sectional view of FIG. 5 (d), the wooden material 230 is press-molded together with the resin sheet 220 under pre-pressurizing conditions using the molds 151 and 152. Thereby, at least a part of the adhesive 222 is transferred from the smooth resin film 221 to the relatively rough wooden board 230, and the wooden board 200 is temporarily formed by folding the wooden board 230 and folding the surplus portion. 'Is formed. The temporary pressurization conditions may be, for example, a wooden plate 230 having a total thickness of several millimeters, a mold temperature of about 100 ° C. to 150 ° C., a molding pressure of about 9 MPa, and a pressurization time of about 4 minutes.

  Next, as shown in the cross-sectional view of FIG. 5 (e), the molds 151 and 152 are once released to release the resin film 221, and then temporarily formed using the molds 151 and 152 again. 'Is press-molded under this pressure condition. Thereby, the wooden member 200 in which press molding is completed is formed. By removing the resin film 221 before the main pressurization, it is possible to reliably prevent the film from being caught in the wooden member 200. The pressurizing condition may be, for example, press molding of a wooden plate 130 having a total thickness of several mm, a mold temperature of 100 ° C. to 150 ° C., a molding pressure of about 9 MPa, and a pressurization time of about 1 minute.

  Then, the press dies 151 and 152 are released, and the wooden member 200 as shown in FIG. 6 is taken out. FIG. 6 shows a top view and two side views of the wooden member 200 viewed from the top plate portion 201 serving as an exterior surface of a housing or the like. In the illustrated example, the wooden member 200 has a tray shape.

  In the wooden member 200, the occurrence of defects such as cracks or cracks 17 shown in FIG. 2 is suppressed or prevented. Further, the folded portion 205 is formed at a position in accordance with the formation pattern of the adhesive 222 of the resin sheet and is fixed by the transferred adhesive 222. This is because the starting point of folding of the wooden board 230 is determined by the hardness of the transferred adhesive 222, and the portion to which the adhesive 222 has been transferred is folded.

  Therefore, in addition to the effects described in connection with the first embodiment, such as the manufacturing yield of wooden members and the degree of freedom of design can be increased, the folding up of the folding portion 205 can be prevented. In addition, it is possible to improve the aesthetic processing yield by controlling the generation position of the folding unit 205 to a predetermined position. For example, by guiding the folding portion 205 to a casing portion that is to be removed for forming a plug or the like, a casing having a uniform grain that does not substantially have a folding portion may be finally obtained. .

  In addition, the two-stage molding shown in FIGS. 5D and 5E and the peeling of the resin film (resin sheet) during the two-step molding are performed in other embodiments (for example, the steps of FIGS. 3D and 7E). ). On the contrary, although it is difficult to reliably eliminate the possibility of entrainment of the resin film, one-step molding as shown in FIG. 3D and subsequent peeling of the resin film are applied to this embodiment. Also good.

(Third embodiment)
With reference to FIG. 7, the manufacturing method of the wooden member which concerns on 3rd Embodiment is demonstrated. First, as shown in FIG. 7A, for example, a screen mesh 360 is placed on a wooden board 331 that can be a decorative layer, and an adhesive 370 is rubbed with a squeegee 365. The screen mesh 360 has an opening 362 having a predetermined pattern at a predetermined position, and an adhesive 332 is printed on the wooden board 331 according to the pattern of the opening 362 as shown in FIG. Is done. The adhesive 332 can be, for example, a thermosetting adhesive. For the adhesive 332, a resin having high hardness and high water repellency is preferably used.

  Next, as shown in the cross-sectional view of FIG. 7 (c), the surface on which the adhesive 332 is provided is set to the outside, and the wooden board 331 is temporarily attached with an additional wooden board 333 through the adhesive 335 as necessary. The wooden plywood 330 is stacked and softened in, for example, water vapor 140. As an example, the wooden board 333 may be a thinning material, and the adhesive 335 may be a corn starch thermosetting adhesive.

  In the above description, the adhesive 332 is printed on the wooden board 331 before temporary stacking, but it is also possible to print the adhesive 332 on the wooden board 331 after temporarily stacking the wooden board 330.

  Next, as shown in the cross-sectional view of FIG. 7D, the resin sheet 320 and the wooden board 330 are overlapped and disposed between the female mold 151 and the male mold 152. The resin sheet 320 may be a PET film, for example. Other resin sheets described in relation to the resin sheet 120 according to the first embodiment may be used. The wooden plate 330 is disposed such that the decorative layer 331 is positioned on the female mold 151 side, and the resin sheet 320 is disposed between the female mold 151 and the wooden plate 330. Therefore, the adhesive 332 of the wooden board 330 is brought into contact with the surface of the resin sheet 320.

  Next, as shown in the cross-sectional view of FIG. 7 (e), the wooden material 330 is press-molded together with the resin sheet 320 using the molds 151 and 152. Thereby, the wooden member 300 is formed. For example, in the press molding of the wooden plate 330 having a total thickness of several mm, the mold temperature can be set to 100 ° C. to 150 ° C., the molding pressure can be set to about 9 MPa, and the pressing time can be set to about 5 minutes.

  Then, the press dies 151 and 152 are released, and the wooden member 300 as shown in FIG. 8 is taken out. FIG. 8 shows a top view and two side views of the wooden member 300 when the top plate 301 serving as an exterior surface of a housing or the like is viewed upward. In the illustrated example, the wooden member 300 has a tray shape.

  In the wooden member 300, generation | occurrence | production of the defect like the crack or the crack 17 shown in FIG. 2 is suppressed or prevented. Further, the folded portion 305 is formed at a position according to the printing pattern of the adhesive 332 and is fixed by the adhesive 332. This is because the starting point of folding of the wooden board 330 is determined by the hardness of the printed adhesive 332 and the resin sheet 320 in contact with the printed adhesive 332, and the printed portion of the adhesive 332 is folded.

  Therefore, in the wooden member 300, the effects described in relation to the first embodiment such as an increase in the manufacturing yield and the degree of freedom of design, the prevention of the subsequent folding up of the folded portion, and the position control are possible. The effects described in relation to the second embodiment can be achieved.

  Next, examples related to the first to third embodiments described above and an example for comparison will be described.
