Description

本発明は、フレキシブル基板の成形方法、及びフレキシブル基板成形治具に関するものである。 The present invention relates to a flexible substrate molding method and a flexible substrate molding jig.

図５に示すように、第１リジット基板３２ａと第２リジット基板３２ｂとをフレキシブル基板２で電気的に接続した複合基板３３がある。このような複合基板３３は、フレキシブル基板２が折り曲げ成形されて使用されるのが一般的である。 As shown in FIG. 5, there is a composite substrate 33 in which a first rigid substrate 32 a and a second rigid substrate 32 b are electrically connected by a flexible substrate 2. Such a composite substrate 33 is generally used by bending the flexible substrate 2.

フレキシブル基板２を折り曲げ成形する方法としては、図６（ａ）、（ｂ）に示すように、フレキシブル基板２の表面２ａ又は裏面２ｂに、断面が円形の棒状治具３４を押し当てながら、棒状治具３４を支点にフレキシブル基板２を折り曲げて成形（フォーミング）する。 As a method of bending the flexible substrate 2, as shown in FIGS. 6A and 6B, a bar-shaped jig 34 having a circular cross section is pressed against the front surface 2a or the back surface 2b of the flexible substrate 2. The flexible substrate 2 is bent and formed (forming) with the jig 34 as a fulcrum.

本発明に係るフレキシブル基板の成形方法、及びこの成形方法に用いるフレキシブル基板成形治具を図面に基づいて説明する。 A flexible substrate molding method and a flexible substrate molding jig used in the molding method according to the present invention will be described with reference to the drawings.

まず、フレキシブル基板の成形方法について述べる。 First, a method for forming a flexible substrate will be described.

なお、図１（ａ）に示すフレキシブル基板２の上側の面を表面とし、下側の面を裏面とする。 In addition, let the upper surface of the flexible substrate 2 shown to Fig.1 (a) be a surface, and let the lower surface be a back surface.

図１（ａ）、（ｂ）に示すように、本実施の形態に係るフレキシブル基板２の成形方法は、フレキシブル基板２を挟む第１の工程と、フレキシブル基板２を挟んだ箇所を支点として折り曲げる第２の工程とを備える。 As shown in FIGS. 1A and 1B, the method for forming a flexible substrate 2 according to the present embodiment is a first step of sandwiching the flexible substrate 2 and bends with a portion sandwiching the flexible substrate 2 as a fulcrum. A second step.

第１の工程は、フレキシブル基板２の表面２ａに接触する第１接触面７を有する第１接触部８と、フレキシブル基板２の裏面２ｂに接触する第２接触面１９を有する第２接触部２０と、により行う。 The first step includes a first contact portion 8 having a first contact surface 7 that contacts the surface 2 a of the flexible substrate 2 and a second contact portion 20 having a second contact surface 19 that contacts the back surface 2 b of the flexible substrate 2. And do.

また、第１の工程は、１つの挟み治具５（図２参照）により行う。すなわち、フレキシブル基板成形治具１は挟み治具５からなる。 In addition, the first step is performed with one clamping jig 5 (see FIG. 2). That is, the flexible substrate forming jig 1 includes a sandwiching jig 5.

図１（ａ）に示すように、第１の工程では、フレキシブル基板成形治具１の第１接触部８と第２接触部２０とを離間させ、第１接触部８と第２接触部２０との間にフレキシブル基板２の折り曲げ位置が配置されるようにフレキシブル基板成形治具１を移動させ、フレキシブル基板２を折り曲げるべき折り線３５（図５参照）に沿わせるように第１接触部８と第２接触部２０とを位置決めし、第１接触部８と第２接触部２０とを近接させる。このとき、フレキシブル基板２の表裏面に対して第１接触面７及び第２接触面１９を平行に当接させる。フレキシブル基板２に対して、第１接触面７及び第２接触面１９は広い面積で面接触されるため、フレキシブル基板２を傷めることがない。 As shown in FIG. 1A, in the first step, the first contact portion 8 and the second contact portion 20 of the flexible substrate forming jig 1 are separated from each other, and the first contact portion 8 and the second contact portion 20 are separated. The flexible substrate forming jig 1 is moved so that the bending position of the flexible substrate 2 is placed between the first contact portion 8 and the flexible substrate 2 along the fold line 35 (see FIG. 5) to be bent. And the second contact portion 20 are positioned, and the first contact portion 8 and the second contact portion 20 are brought close to each other. At this time, the first contact surface 7 and the second contact surface 19 are brought into contact with the front and back surfaces of the flexible substrate 2 in parallel. Since the first contact surface 7 and the second contact surface 19 are in surface contact with the flexible substrate 2 in a wide area, the flexible substrate 2 is not damaged.

図１（ｂ）に示すように、この後、フレキシブル基板２を挟んだ箇所を支点としてフレキシブル基板２を第１接触部８又は第２接触部２０に沿って折り曲げる（第２の工程）。このとき、フレキシブル基板２は第１接触部８と第２接触部２０との間に挟まれているため、第１接触部８又は第２接触部２０がフレキシブル基板２上を滑ることはなく、フォーミングの精度を向上させることができる。 As shown in FIG. 1B, thereafter, the flexible substrate 2 is bent along the first contact portion 8 or the second contact portion 20 with a location sandwiching the flexible substrate 2 as a fulcrum (second step). At this time, since the flexible substrate 2 is sandwiched between the first contact portion 8 and the second contact portion 20, the first contact portion 8 or the second contact portion 20 does not slide on the flexible substrate 2, The accuracy of forming can be improved.

このように、フレキシブル基板２を挟む第１の工程と、フレキシブル基板２を挟んだ箇所を支点として折り曲げる第２の工程と、を備える方法でフレキシブル基板２を成形するため、フォーミングの精度を向上させることができ、フレキシブル基板２を容易に所望の位置で折り曲げ成形できる。 Thus, since the flexible substrate 2 is formed by a method including the first step of sandwiching the flexible substrate 2 and the second step of bending the portion sandwiching the flexible substrate 2 as a fulcrum, the forming accuracy is improved. The flexible substrate 2 can be easily bent at a desired position.

第１の工程は、フレキシブル基板２の表面２ａに接触する第１接触面７を有する第１接触部８と、フレキシブル基板２の裏面２ｂに接触する第２接触面１９を有する第２接触部２０と、により行うため、第１接触部８又は第２接触部２０がフレキシブル基板２上を滑るのを防ぐことができ、フレキシブル基板２のフォーミングの精度を向上させることができる。 The first step includes a first contact portion 8 having a first contact surface 7 that contacts the surface 2 a of the flexible substrate 2 and a second contact portion 20 having a second contact surface 19 that contacts the back surface 2 b of the flexible substrate 2. Therefore, the first contact portion 8 or the second contact portion 20 can be prevented from sliding on the flexible substrate 2, and the forming accuracy of the flexible substrate 2 can be improved.

また、第１の工程は、１つの挟み治具５により行うため、第１接触部８と第２接触部２０とを片手で取り扱うことができ、フォーミング作業を容易に行うことができる。 Further, since the first step is performed by one pinching jig 5, the first contact portion 8 and the second contact portion 20 can be handled with one hand, and the forming operation can be easily performed.

次に、フレキシブル基板成形治具１について説明する。 Next, the flexible substrate forming jig 1 will be described.

第１接触部８は、第１部材３の前端部に形成されている。また、第１接触部８は、断面矩形のロッド状に形成されると共に、フレキシブル基板２の幅よりも長く形成されている。第１接触面７は、平面状に形成されており、フレキシブル基板２と面接触するようになっている。これにより、第１接触部８と後述する第２接触部２０との間に、より広い面積でフレキシブル基板２を挟み込むことができ、フォーミングの精度が向上する。また、第１接触部８は、隅部に面取りが施されており、フレキシブル基板２を傷めないようになっている。 The first contact portion 8 is formed at the front end portion of the first member 3. In addition, the first contact portion 8 is formed in a rod shape having a rectangular cross section, and is longer than the width of the flexible substrate 2. The first contact surface 7 is formed in a planar shape and comes into surface contact with the flexible substrate 2. Thereby, the flexible substrate 2 can be sandwiched with a wider area between the first contact portion 8 and a second contact portion 20 described later, and the forming accuracy is improved. Further, the first contact portion 8 is chamfered at a corner portion so that the flexible substrate 2 is not damaged.

第１屈曲部９は、第１接触面７がフレキシブル基板２に接触したとき、フレキシブル基板２に接続されたリジット基板（図５参照）やフレキシブル基板２の表裏面から突起する部品（図示せず）等を避けるように屈曲されている。具体的には、第１屈曲部９は、第１接触面７がフレキシブル基板２に接触するときフレキシブル基板２から離間する方向に屈曲されている。第１屈曲部９は、第１接触面７がフレキシブル基板２に接触したときフレキシブル基板２に対して垂直に延びる垂直部１２と、垂直部１２から屈曲され第１接触部８と同方向に延びる延長部１３と、を備える。また、第１屈曲部９の断面積は、第１接触部８と同等又は第１接触部８よりも小さく形成されている。これにより、第１屈曲部９は、フレキシブル基板成形治具１でフレキシブル基板２を挟んだときの力が強すぎたとき、適宜変形して余分な力を吸収できるようになっている。なお、第１屈曲部９は、上述の形状に限定されるものではなく、使用形態に応じた適宜の形状に屈曲されればよい。 When the first contact surface 7 contacts the flexible substrate 2, the first bent portion 9 is a rigid substrate (see FIG. 5) connected to the flexible substrate 2 or a component protruding from the front and back surfaces of the flexible substrate 2 (not shown). ) Is bent to avoid.

図４に示すように、第１留具取付部１０と第２留具取付部２２とには、フレキシブル基板成形治具１の前端側が閉じられたとき互いに当接して回動を規制するための第１ストッパ１０ａ及び第２ストッパ２２ａが形成されている。また、第１接触面７と第２接触面１９とは、第１ストッパ１０ａ及び第２ストッパ２２ａが互いに当接したとき、平行かつ所定の間隔ｇを隔てて離間するように形成されている。所定の間隔ｇは、フレキシブル基板２の厚さより若干小さな寸法に設定されている。これにより、第１接触面７と第２接触面１９との間にフレキシブル基板２を挟むとき、第１接触面７及び第２接触面１９がそれぞれフレキシブル基板２の表裏面に対して平行に当接するようになっている。 As shown in FIG. 4, the first fastener attaching portion 10 and the second fastener attaching portion 22 are in contact with each other when the front end side of the flexible substrate forming jig 1 is closed to restrict rotation. A first stopper 10a and a second stopper 22a are formed. Further, the first contact surface 7 and the second contact surface 19 are formed so as to be separated from each other with a predetermined gap g when the first stopper 10a and the second stopper 22a come into contact with each other. The predetermined interval g is set to a dimension slightly smaller than the thickness of the flexible substrate 2. Thus, when the flexible substrate 2 is sandwiched between the first contact surface 7 and the second contact surface 19, the first contact surface 7 and the second contact surface 19 are in contact with the front and back surfaces of the flexible substrate 2, respectively. It comes to touch.

このように、フレキシブル基板成形治具１は、フレキシブル基板２の表面２ａに接触する第１接触面７を有する第１接触部８を備える第１部材３と、フレキシブル基板２の裏面２ｂに接触する第２接触面１９を有する第２接触部２０を備える第２部材４と、を備えるものとしたため、第１部材３と第２部材４との間にフレキシブル基板２を挟むことができ、フレキシブル基板２を容易に所望の位置で折り曲げ形成できる。 As described above, the flexible substrate forming jig 1 contacts the first member 3 including the first contact portion 8 having the first contact surface 7 that contacts the surface 2 a of the flexible substrate 2 and the back surface 2 b of the flexible substrate 2. Since the second member 4 including the second contact portion 20 having the second contact surface 19 is provided, the flexible substrate 2 can be sandwiched between the first member 3 and the second member 4, and the flexible substrate 2 can be easily bent at a desired position.

第１部材３は、第１接触部８から延びる第１屈曲部９と、第１屈曲部９に第１留具取付部１０を介して設けられた第１取っ手部１１とを備え、第２部材４は、第２接触部２０から延びる第２屈曲部２１と、第２屈曲部２１に第２留具取付部２２を介して設けられた第２取っ手部２３とを備えるものとしたため、第１取っ手部１１及び第２取っ手部２３を操作することによりフレキシブル基板２を容易に折り曲げ成形できる。 The first member 3 includes a first bent portion 9 extending from the first contact portion 8, and a first handle portion 11 provided on the first bent portion 9 via a first fastener attaching portion 10. The member 4 includes the second bent portion 21 extending from the second contact portion 20 and the second handle portion 23 provided on the second bent portion 21 via the second fastener attaching portion 22. By operating the first handle portion 11 and the second handle portion 23, the flexible substrate 2 can be easily bent.

なお、第１の工程では、１つの挟み治具５に備えられた第１接触部８と第２接触部２０との間にフレキシブル基板２を挟むものとしたが、第１接触部８と第２接触部２０は別々の工具に備えられたものであってもよい。 In the first step, the flexible substrate 2 is sandwiched between the first contact portion 8 and the second contact portion 20 provided in one sandwiching jig 5. The two contact portions 20 may be provided in separate tools.

また、第１部材３と第２部材４とは留具６を介して回動自在に連結されるものとしたが、これに限るものではない。例えば、第１部材３と第２部材４とは、後端同士を図示しない板ばね部材で連結されたトング状のものであってもよい。 Moreover, although the 1st member 3 and the 2nd member 4 shall be connected rotatably via the fastener 6, it does not restrict to this. For example, the first member 3 and the second member 4 may be of a tong shape in which rear ends are connected by a leaf spring member (not shown).
