Description

本発明は、樹脂部材と樹脂部材あるいは樹脂部材と樹脂以外の部材とを固定する際に用いられる固定方法の一つである熱かしめに関するものであり、詳しくは、この熱かしめ作業の結果である接合品質の安定化を図るものである。   The present invention relates to heat caulking, which is one of fixing methods used when fixing a resin member and a resin member or a resin member and a member other than resin, and more specifically, is a result of the heat caulking operation. It is intended to stabilize the bonding quality.

従来から、樹脂部材同士あるいは樹脂部材と樹脂以外の素材からなる部材との固定には、一方の樹脂部材にはかしめ部として突起を設け、さらに他方の部材には前記突起と対応する位置に貫通孔を設け、該突起を該貫通孔に貫挿させた後、突出した該突起の先端に熱と押圧力とを加え、軟化した突起の先端近傍を潰すようにして両部材を固定する所謂熱かしめが広く行われている。また、一方の樹脂部材に薄肉壁状の突起を設け、この薄肉壁を倒す方向に変形させることで、薄肉壁の側面にその外縁が接するように配置された例えばレンズ部品等を固定する熱かしめも広く行なわれている。   Conventionally, for fixing between resin members or between a resin member and a member made of a material other than resin, one resin member has a protrusion as a caulking portion, and the other member penetrates to a position corresponding to the protrusion. After providing the hole and inserting the protrusion into the through hole, heat and pressing force are applied to the tip of the protruding protrusion, and both members are fixed so as to crush the vicinity of the tip of the softened protrusion. Caulking is widely performed. In addition, a thin wall-shaped protrusion is provided on one of the resin members, and the thin wall is deformed in a tilting direction so that the outer edge of the thin wall is in contact with the side edge of the thin wall. Is also widely practiced.

この作業には被接合部に対して熱を加えるために、電気抵抗による発熱が広く利用されてきた。少量生産に適用する場合は、はんだ鏝の先端を適宜加工して手持ち工具とし、樹脂からなる突起を１点１点かしめることが行われている。また、より作業効率を高めるためには、複数のかしめ工具を所定の間隔で治具等に固定して一度に押圧したり、特許文献１の記載のように、熱容量が大きく蓄熱作用を持つ発熱体に突起状の加熱押圧部（以下作用端と記す）を複数立設し、樹脂部材の複数の突起を一度にかしめる工夫がなされてきた。さらに、このかしめ作業の品質の安定化を目的とし、作用端を備えたかしめヘッドをエアシリンダやモータ等のアクチュエータによって昇降させ、突起の潰し量や加圧力等の作業条件の繰り返し精度を高めて、かしめ品質を均一化する工夫がなされてきた（特許文献１、特許文献２）。   In this operation, heat generated by electric resistance has been widely used in order to apply heat to the bonded portion. When applied to small-scale production, the tip of the soldering iron is appropriately processed to make a hand-held tool, and the protrusions made of resin are caulked one by one. Further, in order to further improve the working efficiency, a plurality of caulking tools are fixed to a jig or the like at a predetermined interval and pressed at once, or heat generation with a large heat capacity and a heat storage action as described in Patent Document 1 is performed. A device has been devised in which a plurality of protrusion-like heat pressing portions (hereinafter referred to as working ends) are erected on the body, and the plurality of protrusions of the resin member are caulked at a time. Furthermore, for the purpose of stabilizing the quality of the caulking work, the caulking head having the working end is moved up and down by an actuator such as an air cylinder or a motor to improve the repetition accuracy of work conditions such as the amount of protrusion crushing and the applied pressure. The invention has been devised to make the caulking quality uniform (Patent Document 1, Patent Document 2).

さらに加熱方式に関しては、特許文献１および２の記載にあるコンスタントヒート方式に対して、近年では特許文献３の記載のように、パルスヒート電源が出力する電流（詳しくは出力トランスの２次側電流）を直接作用端に流し、この作用端自身の抵抗発熱を利用するパルスヒート方式が採用されるようになってきた。ここでパルスヒート方式とは、熱かしめに際して樹脂と直接接触する作用端を比較的電気抵抗の高い導電体で形成し、これに瞬間的に大電流を流して抵抗発熱による急激な温度上昇を得、さらに加熱中も作用端の温度をフィードバック制御することで、精度の高い温度制御を行う方法であり、熱容量の比較的大きな発熱体に作用端を設けて、定常的に加熱するコンスタントヒート方式とは区別される。

Here, the pulse heat method is to form a working end that is in direct contact with the resin during heat caulking with a conductive material having a relatively high electric resistance, and a large current is instantaneously passed through it to obtain a rapid temperature rise due to resistance heating. In addition, the temperature of the working end is also feedback-controlled during heating, and the temperature is controlled with high accuracy.

まず、一般的な熱かしめの一例を要部断面図である図６に基づいて説明する。図６において、符号５１は一方の部材であり、例えば熱可塑性樹脂を射出成型したケースとする。また、符号５２は他方の部材であり、例えば電気部品の基板であるとする。ここで一方の部材５１は、かしめ部である円柱状の突起５１Ａを備え、他方の部材５２は貫通孔５２Ａを備えており、図６（ａ）〜（ｃ）の左側の図では、突起５１Ａが貫通孔５２Ａに貫挿され、下降してきた作用端５３、５４が突起５１Ａに当接した状態を示している。また、図６（ａ）〜（ｃ）の右側の図は、作用端５３、５４が突起５１Ａに対し熱と押圧力を加えて、突起５１Ａの先端側が潰れるように変形した様子（符号５１Ａ′）を示している。そして広く一般的に行なわれているように、これら作用端５３、５４の先端にはドーム状の凹所が加工されており（５３Ａ、５４Ａ）、この凹所がかしめ作業の結果である変形後の突起５１′の形状として転写される。   First, an example of general heat caulking will be described with reference to FIG. In FIG. 6, reference numeral 51 denotes one member, for example, a case in which a thermoplastic resin is injection molded. Reference numeral 52 denotes the other member, for example, a substrate of an electrical component. Here, one member 51 is provided with a columnar protrusion 51A that is a caulking portion, and the other member 52 is provided with a through hole 52A. In the left side of FIGS. 6 (a) to 6 (c), the protrusion 51A is provided. Is inserted into the through hole 52A, and the action ends 53 and 54 that have been lowered are in contact with the protrusion 51A. 6A to 6C, the working ends 53 and 54 are deformed so that the tip side of the projection 51A is crushed by applying heat and pressing force to the projection 51A (reference numeral 51A ′). ). As is widely practiced, dome-shaped recesses are processed at the tips of the working ends 53 and 54 (53A and 54A), and these recesses are deformed as a result of caulking work. Is transferred as the shape of the projection 51 '.

そして図６（ａ）〜（ｃ）の右側の図のような状態となった後、熱かしめ装置がパルスヒート方式である場合は、作用端５３、５４の加熱を停止して温度を下げ、変形後の突起５１Ａ′をある程度硬化させてから作用端５３、５４を上方に離隔することで熱かしめ作業が終了する。一方かしめ装置がコンスタントヒート方式の場合は加熱を停止してもすぐに温度が下がらないので、加熱を停止せずそのまま作用端５３、５４を上方に離隔させることで熱かしめ作業が終了する場合もある。しかし、パルスヒート方式の場合には加熱停止後の冷却を早めるため、コンスタントヒート方式の場合は冷却作用を付与するために、かしめ部近傍に冷却風を送風する場合もある。特にコンスタントヒート方式の場合は、軟化した変形後の突起５１Ａ′が凹所５３Ａ、５４Ａに融着して熱かしめ後の仕上がりが悪くなる（糸引き）ため、これを避けたい場合に行なわれる。 And after it will be in the state of the figure on the right side of Fig.6 (a)-(c), when a heat caulking apparatus is a pulse heat system, heating of action ends 53 and 54 is stopped, and temperature is lowered, After the deformed projection 51A ′ is cured to some extent, the working ends 53 and 54 are separated upward to complete the heat caulking operation. On the other hand, if the caulking device is a constant heat system, the temperature does not drop immediately even if heating is stopped. Therefore, the heat caulking operation may be completed by separating the working ends 53 and 54 upward without stopping the heating. is there. However, in the case of the pulse heat method, in order to speed up the cooling after the heating is stopped, in the case of the constant heat method, cooling air may be blown near the caulking portion in order to provide a cooling action. In particular, in the case of the constant heat system, the softened and deformed projection 51A 'is fused to the recesses 53A and 54A and the finish after heat caulking is deteriorated (string drawing).

ここで、図６（ａ）は作用端５３の軸心の位置が突起５１Ａの軸心の位置とほぼ一致して当接し、加熱を伴ってそのまま下方に押圧された様子を示している。これに対して図６（ｂ）および（ｃ）は、左側の図が示すように、作用端５３、５４による加熱および押圧が開始される前の状態で、作用端５３、５４の軸心と突起５１Ａの軸心とが寸法Ｆだけずれた状態を表している。このとき、かしめ装置が手持ち工具であった場合は、図６（ｂ）で示すように、押圧が開始されるとその直後から、手持ち工具の先端である作用端５３の軸心が突起５１Ａの軸心方向に誘導され、右側の図のように、ほぼ正常な熱かしめ結果が得られる。これは、作用端５３の先端に形成されたドーム型の凹所５３Ａの傾斜面と突起５１Ａの先端との接触によって倣い作用が発生し、これに作業者の手が誘導されるからである。 Here, FIG. 6A shows a state in which the position of the axial center of the working end 53 is in contact with the position of the axial center of the protrusion 51A and is pressed downward as it is heated. 6 (b) and 6 (c), on the other hand, show the axes of the working ends 53, 54 in the state before the heating and pressing by the working ends 53, 54 are started, as shown on the left side. This represents a state in which the axis of the protrusion 51A is displaced by a dimension F. At this time, if the caulking device is a hand-held tool, as shown in FIG. 6 (b), immediately after pressing is started, the axis of the working end 53, which is the tip of the hand-held tool, starts from the protrusion 51A. Guided in the axial direction, almost normal heat caulking results are obtained as shown in the right figure. This is because a copying action occurs due to the contact between the inclined surface of the dome-shaped recess 53A formed at the tip of the working end 53 and the tip of the projection 51A, and the operator's hand is guided to this.

これに対して図６（ｃ）で示す現象は、アクチュエータによって昇降するように構成された熱かしめヘッドに作用端５４が設けられている場合を示している。この場合は、軸心のずれ寸法Ｆが維持されたまま熱かしめ作業が行われ、結果として右側の図のように変形後の突起５１Ａ′の中心が貫通孔５２Ａの中心からずれた状態となってしまう。そしてこのような状態になることで、かしめ強度の低下、つまりかしめ品質の低下を招くことになる。加えて、このような熱かしめの結果となった場合、その修正は極めて困難であり、一方の部材５１を廃棄することになった場合には、部材５１の歩留まりまで低下させてしまう。また、図６（ｂ）で説明した手持ち工具の場合のように倣い作用を利用するため、ステージを水平方向に摺動自在にすることも考えられるが、この場合、状態によっては突起５１Ａが倒れる方向に変形してしまい、かえってかしめ品質を低下させてしまう。   On the other hand, the phenomenon shown in FIG. 6C shows a case where the working end 54 is provided in a heat caulking head configured to be moved up and down by an actuator. In this case, the heat caulking operation is performed with the axial center deviation dimension F maintained, and as a result, the center of the deformed projection 51A ′ is displaced from the center of the through hole 52A as shown in the right figure. End up. In such a state, the caulking strength is lowered, that is, the caulking quality is lowered. In addition, when such heat caulking results, the correction is extremely difficult, and when one member 51 is to be discarded, the yield of the member 51 is reduced. Further, in order to use the copying action as in the case of the hand-held tool described with reference to FIG. 6B, it is conceivable to make the stage slidable in the horizontal direction, but in this case, the protrusion 51A falls depending on the state. It will be deformed in the direction, reducing the caulking quality.

このような課題は、かしめ部が前述したような円柱状の突起である場合に限るものではなく、角柱状の突起、あるいは図７で示すような薄肉壁状の突起においても、作用端の先端に傾斜面が存在し、これが突起の先端に当接して直線的に下方へ押圧力を加える場合には、共通して発生し得る問題である。図７は、レンズマウント６１にレンズ６２を固定する場合の従来の熱かしめの様子を示したものである。ここでレンズマウント６１は熱可塑性樹脂からなり、フランジ付きの円筒形状に形成されたものである。レンズマウント６１の段差部にレンズ６２を上方から落とし込むと、環状の薄肉壁６１Ａがレンズ６２の周縁の厚みよりも突出するようになっている。ここで図７（ａ）のように、レンズマウント６１の軸心と作用端６３の軸心とがほぼ一致した状態で、作用端６３の円錐状の傾斜面６３Ａが薄肉壁６１Ａに当接し、熱と下方への押圧力を加えると右側の図のように、環状の薄肉壁６１Ａがレンズ６２の周縁に被さるように変形する。 Such a problem is not limited to the case where the caulking portion is a columnar projection as described above, and the tip of the working end also in a prismatic projection or a thin wall-shaped projection as shown in FIG. This is a problem that may occur in common when there is an inclined surface that is in contact with the tip of the protrusion and linearly applies a downward pressing force. FIG. 7 shows a state of conventional heat caulking when the lens 62 is fixed to the lens mount 61. Here, the lens mount 61 is made of a thermoplastic resin and is formed in a cylindrical shape with a flange. When the lens 62 is dropped into the stepped portion of the lens mount 61 from above, the annular thin wall 61A protrudes beyond the thickness of the periphery of the lens 62. Here, as shown in FIG. 7A, in a state where the axis of the lens mount 61 and the axis of the working end 63 substantially coincide with each other, the conical inclined surface 63A of the working end 63 contacts the thin wall 61A, When heat and a downward pressing force are applied, the annular thin wall 61A is deformed so as to cover the periphery of the lens 62 as shown in the right figure.

しかしながら、図７（ｂ）で示すように、作用端６３がアクチュエータによって昇降するかしめヘッドに設けられたものであり、且つ、レンズマウント６１の軸心と作用端６３の軸心とにずれ（寸法Ｇ）があった場合、右側の図の符号アで示す部分の薄肉壁６１Ａが、十分にレンズ６２の周縁に被さらない状態、つまり、レンズマウント６１とレンズ６２との固定強度不足となってしまう。そこで本発明は、アクチュエータによって昇降するように構成された熱かしめヘッドに作用端が設けられている場合でも、図６（ｃ）または図７（ｂ）に基づいて説明したような、品質の悪いかしめ結果が発生しない熱かしめ装置を提供するものである。   However, as shown in FIG. 7B, the working end 63 is provided on the caulking head that is moved up and down by the actuator, and is shifted (dimensions) between the axis of the lens mount 61 and the axis of the working end 63. When G) is present, the thin wall 61A of the portion indicated by the symbol A in the right figure does not sufficiently cover the periphery of the lens 62, that is, the fixing strength between the lens mount 61 and the lens 62 is insufficient. End up. Therefore, the present invention has poor quality as described with reference to FIG. 6C or FIG. 7B even when the working end is provided in the heat caulking head configured to be moved up and down by the actuator. It is an object of the present invention to provide a heat caulking device that does not generate caulking results.

本発明は第１の態様として、樹脂からなるかしめ部に熱と押圧力を加え、このかしめ部を変形させる熱かしめ装置において、前記かしめ部に直接接触する作用端と、この作用端を支持し、アクチュエータの駆動により前記かしめ部に対して近接および離隔するように直線的に移動するかしめヘッドと、前記作用端が熱かしめのための正常な位置でかしめ部に当接したとき、この当接を検知する検知手段と、この当接のときの前記作用端の前記移動の方向での位置を記憶する記憶手段と、前記かしめ部と同一形状のかしめ部に前記作用端が繰り返し当接したとき、毎回の作用端の前記移動の方向での位置と前記記憶手段が記憶した位置とを比較する比較手段と、この比較手段の比較結果に応じてかしめ動作を停止するコントローラとを備えることを特徴とする熱かしめ装置を提供するものである。 As a first aspect of the present invention, in a heat caulking device that applies heat and pressing force to a caulking portion made of resin and deforms the caulking portion, an action end that directly contacts the caulking portion, and the action end are supported. A caulking head that moves linearly so as to approach and separate from the caulking portion by driving an actuator, and the abutting portion when the working end abuts the caulking portion at a normal position for heat caulking. Detection means for detecting the position, storage means for storing the position of the action end in the moving direction at the time of contact, and when the action end repeatedly comes into contact with a caulking part having the same shape as the caulking part A comparison means for comparing the position of the working end in each movement direction with the position stored in the storage means, and a controller for stopping the caulking operation according to the comparison result of the comparison means. There is provided a heat staking apparatus according to claim.

また本発明は第２の態様として、前記作用端において前記かしめ部に当接する端面の少なくとも一部の領域は、前記移動の方向に垂直に交わる仮想平面に対して傾斜した面であることを特徴とする第１の態様として記載の熱かしめ装置を提供するものである。 According to the second aspect of the present invention, as the second aspect, at least a partial region of the end surface that contacts the caulking portion at the working end is a surface that is inclined with respect to a virtual plane perpendicular to the direction of movement. The thermal caulking device described as the first aspect is provided.

さらに本発明は第３の態様として、前記かしめヘッドからかしめ部の方向に突出し、この方向にこのかしめヘッドに対して摺動可能に設けられた前記作用端と、前記かしめヘッドに設けられ、前記作用端をかしめ部の方向に付勢するばねとを有し、前記検知手段は前記かしめヘッドと前記作用端との相対的な位置の移動を検知することを特徴とする第１又は第２のいずれかの態様として記載の熱かしめ装置を提供するものである。 Furthermore, as a third aspect of the present invention, the caulking head protrudes from the caulking head in the direction of the caulking portion, and the working end provided to be slidable with respect to the caulking head in this direction; the caulking head; A spring for urging the working end in the direction of the caulking portion, and the detecting means detects a relative position movement between the caulking head and the working end. The heat-caulking device described as any embodiment is provided.

加えて本発明は第４の態様として、第１乃至第３のいずれかの態様とした装置を使用して実現できる熱かしめ方法であって、少なくとも次のａ）、ｂ）およびｃ）の工程を有することを特徴とする熱かしめ方法を提供する。
ａ）熱かしめのための正常な位置関係で変形前の前記かしめ部と前記作用端とを当接させ、このときの前記作用端の前記押圧力を加える方向の位置データを記憶する。
ｂ）熱かしめの際に、前記作用端が前記かしめ部と同一形状のかしめ部に当接したとき、この作用端の前記押圧力を加える方向の位置データを取得する。
ｃ）前記工程ａ）で記憶した位置データと前記工程ｂ）で取得した位置データとを比較し、前記工程ｂ）のかしめ部と作用端とが、熱かしめのために正常な位置関係であるか否かを判定する。 In addition, as a fourth aspect of the present invention, there is provided a heat caulking method that can be realized using the apparatus according to any one of the first to third aspects, and includes at least the following steps a), b), and c): A heat caulking method is provided.
a) The caulking portion before deformation is brought into contact with the action end in a normal positional relationship for heat caulking, and position data in a direction in which the pressing force of the action end is applied is stored.
b) When the caulking portion contacts the caulking portion having the same shape as the caulking portion during heat caulking, position data in the direction in which the pressing force of the acting end is applied is acquired.
c) The position data stored in the step a) is compared with the position data acquired in the step b), and the caulking portion and the working end in the step b) are in a normal positional relationship for heat caulking. It is determined whether or not.

本発明の第１の態様によれば、作用端がかしめ部に当接したときの押圧方向の位置が、熱かしめのための正常な位置であるか否か、熱かしめ作業毎にかしめ動作の直前でチェックできるので、異常が検出された場合、かしめ部を変形させる前に装置の動作を停止させることができる。そしてこの異常の検出には、作用端とかしめ部との位置ずれのみならず、たとえば図６で説明した熱かしめにおいて、突起５１Ａが貫通孔５２Ａに完全に貫挿されず、他方の部材５２が突起５１Ａの上部に乗り上げているような状態、あるいは図７で説明した熱かしめにおいて、レンズ６２がレンズマウント６１に正常に嵌合していない状態の検出も含まれる。したがって、第１の態様によれば作用端の先端形状に係わらず、熱かしめの品質の安定を実現すると共に、熱かしめ不良による部品の歩留まりの低下を防ぐことができる。   According to the first aspect of the present invention, whether or not the position in the pressing direction when the working end abuts on the caulking portion is a normal position for heat caulking, and the caulking operation is performed for each heat caulking operation. Since the check can be performed immediately before, when an abnormality is detected, the operation of the apparatus can be stopped before the caulking portion is deformed. For the detection of this abnormality, not only the displacement between the working end and the caulking portion, but also, for example, in the heat caulking described in FIG. 6, the projection 51A is not completely inserted into the through hole 52A, and the other member 52 Detection of a state where the lens 62 is not properly fitted to the lens mount 61 in a state where the lens 62 rides on the upper portion of the protrusion 51A or the heat caulking described with reference to FIG. Therefore, according to the first aspect, regardless of the shape of the tip of the working end, it is possible to achieve stable heat caulking quality and prevent a decrease in component yield due to heat caulking failure.

本発明の第２の態様によれば、作用端の端面の傾斜を利用して位置ずれを判断するので、検出の精度を上げることによって、極端な位置ずれのみならず、一見正常な熱かしめであっても、強度的な問題を内在しているようなかしめ不良の発生を防ぐことが可能となる。これは、一般的に熱かしめを終えた後の位置ずれ量は、目視では確認し難いという問題を解決するものである。   According to the second aspect of the present invention, the positional deviation is determined using the inclination of the end face of the working end. Therefore, by increasing the detection accuracy, not only extreme positional deviation but also seemingly normal heat caulking. Even in such a case, it is possible to prevent the occurrence of caulking defects that have inherent strength problems. This solves the problem that the displacement amount after heat caulking is generally difficult to visually confirm.

本発明の第３の態様によれば、作用端を付勢するように設けられたばねの微細な圧縮長の変化を検知することで、作用端がかしめ部に当接したことを知ることができる。したがって、別途圧力センサや歪みゲージを設けることなく、かしめ作業そのもののために設けられた、ばねとこのばねの圧縮長の変化を検知する検知手段を利用するので、構造が複雑にならず、安価な熱かしめ装置を提供することができる。また、本発明の第４の態様によれば、前述したような効果を得る熱かしめ方法が実現できる。   According to the third aspect of the present invention, it is possible to know that the working end has come into contact with the caulking portion by detecting a minute change in the compression length of the spring provided to urge the working end. . Therefore, without using a separate pressure sensor and strain gauge, the spring and the detection means for detecting changes in the compression length of the spring are used for the caulking work itself, so the structure is not complicated and inexpensive. A heat staking device can be provided. Moreover, according to the 4th aspect of this invention, the heat caulking method which acquires the above effects is realizable.

次に添付図面を参照して本発明に係る熱かしめ装置を詳細に説明する。   Next, a heat staking apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

図１は本発明に係る熱かしめ装置の全体を示す側面図である。図１において、符号１は基台、２は基台１に立設された支柱、３は支柱２に２個のスライドブロック４とスライドレール５とを介して昇降可能に支持されたかしめヘッド、６はボールねじ６Ａとナット３Ａとの螺合によりかしめヘッド３を昇降させるモータ、７はかしめヘッド３からかしめ部が載置されるステージ８に向かって突出して設けられた作用端、９は出力トランスを内蔵したパルスヒート電源、１０はコントローラである。 FIG. 1 is a side view showing the entirety of a heat caulking apparatus according to the present invention. In FIG. 1, reference numeral 1 is a base, 2 is a column that is erected on the base 1, 3 is a caulking head that is supported by the column 2 through two slide blocks 4 and slide rails 5 so as to be movable up and down, 6 is a motor for raising and lowering the caulking head 3 by screwing the ball screw 6A and the nut 3A, 7 is a working end provided to project from the caulking head 3 toward the stage 8 on which the caulking portion is placed, and 9 is an output. A pulse heat power source with a built-in transformer, 10 is a controller.

図２は図１で示したかしめヘッド３の内部構造を示す要部断面図である。図２において、符号２１はハウジング、２２はハウジング２１に固定され、上端の周囲に雄ねじが刻まれた円筒状の押圧管、２３は有底円筒状で内面に雌ねじが刻まれたダイヤル、２４は押圧管２２の内部に設けられた圧縮コイルばねである。圧縮コイルばね２４の上端は押圧ピース２５に当接しており、この押圧ピース２５は、ダイヤル２３に設けられた円柱状の突起２３Ａに回転自在に嵌合すると共に、押圧ピース２５に圧入されたピン２５Ａが押圧管２２に軸方向に設けられたスリット２２Ａに挿通した状態で設けてある。   FIG. 2 is a cross-sectional view of the main part showing the internal structure of the caulking head 3 shown in FIG. In FIG. 2, reference numeral 21 is a housing, 22 is fixed to the housing 21, and is a cylindrical pressure tube with a male screw engraved around the upper end, 23 is a bottomed cylindrical shape, and a dial with an internal screw engraved on the inner surface, 24 A compression coil spring provided inside the pressing tube 22. The upper end of the compression coil spring 24 is in contact with a pressing piece 25, and this pressing piece 25 is rotatably fitted to a cylindrical protrusion 23 </ b> A provided on the dial 23 and is a pin press-fitted into the pressing piece 25. 25A is provided in a state of being inserted through a slit 22A provided in the pressing tube 22 in the axial direction.

また、スリット２２Ａに沿った押圧管２２の表面には、押圧管２２の軸方向に目盛が表示してある。したがって、ダイヤル２３を回すことで前記雄ねじと雌ねじの螺合により押圧ピース２５は回転することなく上下に移動する。この押圧ピース２５の上下動により圧縮コイルばね２２の圧縮長が変化し、圧縮コイルばね２２の下端が付勢する押圧シャフト２６に対する付勢力が変化すると共にピン２５Ａが指す前記目盛の位置が変化するので、操作者はピン２５Ａの位置で前記付勢力を知ることができる。ここで、押圧シャフト２６には大径部２６Ａが設けてあり、これがハウジング２１の内壁に当接することで、作用端７のかしめヘッド３からの最大突出長を規制している。 Further, a scale is displayed in the axial direction of the pressing tube 22 on the surface of the pressing tube 22 along the slit 22A. Therefore, when the dial 23 is turned, the pressing piece 25 moves up and down without rotating due to the screwing of the male screw and the female screw. As the pressing piece 25 moves up and down, the compression length of the compression coil spring 22 changes, the urging force against the pressing shaft 26 urged by the lower end of the compression coil spring 22 changes, and the position of the scale pointed by the pin 25A changes. Therefore, the operator can know the urging force at the position of the pin 25A. Here, the pressing shaft 26 is provided with a large-diameter portion 26 </ b> A, which is in contact with the inner wall of the housing 21, thereby restricting the maximum projecting length of the working end 7 from the caulking head 3.

押圧シャフト２６の下端には絶縁ブロック２７が固定されており、これに全体的には略Ｖの字形状の作用端７が固定されている。この略Ｖの字形状の両上端７Ａ、７Ｂは、図１に基づいて説明した第４のケーブル１４によりパルスヒート電源９と接続され、加熱用の給電が行なわれる。また、この略Ｖの字形状の下端は上下方向に伸びる円柱形状に形成され、その下端面にはドーム型の凹所が形成されている。また、この円柱形状の下端近傍の側面には熱電対７Ｃが固着され、図１に基づいて説明した第５のケーブル１５によりパルスヒート電源９と接続され、作用端７の下端近傍の温度データをパルスヒート電源９にフィードバックする。   An insulating block 27 is fixed to the lower end of the pressing shaft 26, and a substantially V-shaped working end 7 is fixed to the insulating block 27 as a whole. Both upper ends 7A and 7B of the substantially V-shape are connected to the pulse heat power source 9 by the fourth cable 14 described with reference to FIG. 1, and power is supplied for heating. Further, the lower end of the substantially V-shape is formed in a columnar shape extending in the vertical direction, and a dome-shaped recess is formed on the lower end surface. Further, a thermocouple 7C is fixed to the side surface in the vicinity of the lower end of the columnar shape, and is connected to the pulse heat power source 9 by the fifth cable 15 described with reference to FIG. Feedback is made to the pulse heat power source 9.

また、押圧シャフト２６には、押圧シャフト２６と共に上下動するように固定された支持板２８が設けられ、さらに支持板２８には押圧シャフト２６と平行に設けられた円柱状の鉄心２９が固定されている。この鉄心２９とハウジング２１に固定されたコイル３０が変位計３１を構成し、ハウジング２１と押圧シャフト１６との相対的な移動、つまりかしめヘッド３と作用端７との相対的な移動を検知し、図１に基づいて説明した第２のケーブル１２を介してコントローラ１０に移動量データを出力する。   Further, the pressing shaft 26 is provided with a support plate 28 fixed so as to move up and down together with the pressing shaft 26, and a cylindrical iron core 29 provided in parallel with the pressing shaft 26 is fixed to the support plate 28. ing. The iron core 29 and the coil 30 fixed to the housing 21 constitute a displacement meter 31 that detects relative movement between the housing 21 and the pressing shaft 16, that is, relative movement between the caulking head 3 and the working end 7. The movement amount data is output to the controller 10 via the second cable 12 described with reference to FIG.

次に図３および図４に基づいて、本発明による熱かしめ装置および熱かしめ方法の動作を説明する。図３においては、従来の説明のために図６で掲げた熱かしめと同様の例を取り上げ共通の要素には同じ符号を用いて説明する。また、図３および図４においては、図２で説明したかしめヘッド３および作用端７の要部のみを簡略化して図示し、説明を行なう。図３および図４では図２で描いた作用端７の受電部および熱電対を省略して作用端７全体を円柱形で表し、かしめ部に当接する端面に加工されたドーム型の凹所７Ｄが描かれている。また、かしめヘッド３においても図２で描いた内部構造は省略し、押圧シャフト２６の大径部２６Ａとハウジング２１との位置関係のみを示している。つまり図２における変位計３１の示す値を寸法Ｌとして表している。   Next, based on FIG. 3 and FIG. 4, operation | movement of the heat crimping apparatus and the heat crimping method by this invention is demonstrated. In FIG. 3, the same example as the heat caulking shown in FIG. 6 is taken for the conventional explanation, and common elements are described using the same reference numerals. 3 and 4, only the main parts of the caulking head 3 and the working end 7 described in FIG. 2 are shown in a simplified manner for explanation. 3 and 4, the power receiving portion and the thermocouple depicted in FIG. 2 are omitted, and the entire working end 7 is shown in a cylindrical shape. The dome-shaped recess 7D is processed into an end face that contacts the caulking portion. Is drawn. In the caulking head 3 as well, the internal structure depicted in FIG. 2 is omitted, and only the positional relationship between the large-diameter portion 26A of the pressing shaft 26 and the housing 21 is shown. That is, the value indicated by the displacement meter 31 in FIG.

図３は、熱かしめの対象である一方の部材５１と他方の部材５２との最初の熱かしめ作業の前に、各種条件を設定する様子を表している。また、図４は図３の設定が終了し、図３のかしめ対象と同一品種の部材に熱かしめ作業を行う様子を表している。まず図３（ａ）において、かしめヘッド（図１、２の符号３）は上方に位置しており、作用端７はかしめ部である突起５１Ａから離隔しているので、押圧シャフト２６は圧縮コイルばね（図２の符号２４）に下方に付勢され、大径部２６Ａの下面はハウジング２１の内面に接触している。したがって、大径部２６Ａとハウジング２１との間隔をＬとするとＬ＝０ｍｍである。ここで操作者はコントローラ（図１の符号１０）に備わったリセットスイッチで変位計が示す値を０ｍｍにゼロ点補正し、ダイヤル（図２の符号２３）を回して所望の押圧力に設定する。ここで設定される押圧力とは、作用端がかしめ部である突起５１Ａを最後まで押し潰した時点での押圧力を意味する（この例では２０Ｎとする）。   FIG. 3 shows a state in which various conditions are set before the first heat caulking operation between one member 51 and the other member 52 to be heat caulked. FIG. 4 shows a state where the setting of FIG. 3 is completed and the heat caulking work is performed on the members of the same type as the caulking target of FIG. First, in FIG. 3A, the caulking head (reference numeral 3 in FIGS. 1 and 2) is located above, and the working end 7 is separated from the projection 51A that is the caulking portion. The spring (reference numeral 24 in FIG. 2) is biased downward, and the lower surface of the large-diameter portion 26 A is in contact with the inner surface of the housing 21. Therefore, when the distance between the large diameter portion 26A and the housing 21 is L, L = 0 mm. Here, the operator uses the reset switch provided in the controller (reference numeral 10 in FIG. 1) to zero-correct the value indicated by the displacement meter to 0 mm, and turns the dial (reference numeral 23 in FIG. 2) to set the desired pressing force. . The pressing force set here means the pressing force at the time when the projection 51A whose working end is the caulking portion is crushed to the end (in this example, 20N).

次に図３（ｂ）では、作用端７が突起５１Ａの根元の近傍に位置するよう部材５１、５２を移動し、コントローラ１０に備わったジョグレバーを押し下げる。これによりモータ（図１の符号６）が駆動し、かしめヘッド３が下降する。作用端７が他方の部材５２の表面に当接すると、ハウジング２１は更に下降を続けるが大径部２６Ａは下降が阻止されているので、大径部２６Ａとハウジングとに隙間が生じる。ここで、間隔Ｌが予め設定してある値Ｌ１（この例では０．５ｍｍとする）に達するとモータ６は自動的に停止し、かしめヘッド３はその位置に保持される。そしてコントローラ１０はかしめヘッド３つまりはハウジング２１の高さ方向の位置をモータ６のエンコーダ出力からＭ１として記憶する。   Next, in FIG. 3B, the members 51 and 52 are moved so that the working end 7 is positioned in the vicinity of the base of the protrusion 51A, and the jog lever provided in the controller 10 is pushed down. As a result, the motor (reference numeral 6 in FIG. 1) is driven, and the caulking head 3 is lowered. When the working end 7 abuts against the surface of the other member 52, the housing 21 continues to descend, but the large-diameter portion 26A is prevented from descending, so that a gap is generated between the large-diameter portion 26A and the housing. Here, when the interval L reaches a preset value L1 (0.5 mm in this example), the motor 6 automatically stops and the caulking head 3 is held at that position. Then, the controller 10 stores the position of the caulking head 3, that is, the height direction of the housing 21 as M <b> 1 from the encoder output of the motor 6.

次に図３（ｃ）では、操作者は前記ジョグレバーを押し上げてかしめヘッド３を上昇させ、他方の部材５２と共にかしめ部である突起５１Ａをこの熱かしめのための正常な位置に移動させる。そして再びジョグ動作でかしめヘッドを下降させることで、作用端７に設けられたドーム型の凹所７Ｄのほぼ中央に突起５１Ａが当接するようにする。ここでＬ＝Ｌ１（０．５ｍｍ）となったとき前述と同様に自動的にハウジング２１の下降が停止し、このときのハウジング２１の高さ方向の位置をＭ２として記憶する。つまり、図３（ｃ）では、熱かしめのための正常な位置で作用端７がかしめ部に当接したときのハウジングの高さ方向の位置が、Ｍ２＋０．５ｍｍであると認識して記憶するものであり、換言すると、このときの作用端７の高さ方向の位置を記憶するものである。さらにこの設定段階では、熱かしめのための正常な位置に対してかしめ部が水平方向に位置ずれしたときの許容値を、位置ずれして当接した作用部７の、高さの方向の位置の差に置き換えた許容値Ｘ（この例では０．３ｍｍとする）として設定し、コントローラ１０に記憶させる。   Next, in FIG. 3C, the operator pushes up the jog lever to raise the caulking head 3, and moves the protrusion 51 </ b> A, which is the caulking portion, together with the other member 52 to a normal position for this heat caulking. Then, the caulking head is lowered again by the jog operation so that the projection 51A comes into contact with the approximate center of the dome-shaped recess 7D provided at the working end 7. Here, when L = L1 (0.5 mm), the lowering of the housing 21 is automatically stopped as described above, and the position in the height direction of the housing 21 at this time is stored as M2. That is, in FIG. 3C, the position in the height direction of the housing when the working end 7 is in contact with the caulking portion at a normal position for heat caulking is recognized as M2 + 0.5 mm and stored. In other words, the position in the height direction of the working end 7 at this time is stored. Furthermore, in this setting stage, the allowable value when the caulking portion is displaced in the horizontal direction with respect to the normal position for heat caulking is set to the position in the height direction of the acting portion 7 that is in contact with the displacement. Is set as an allowable value X (in this example, 0.3 mm) that is replaced with the difference between the values and stored in the controller 10.

図３に基づいて説明した各種設定が終了したら、図４に基づいて説明する実際の熱かしめ作業に入る。図４（ｄ）は、熱かしめの対象である一方の部材５１および他方の部材５２のセッティングが終了した後、操作者が熱かしめ作業の開始を指示するスタートスイッチを押下し、モータ６の駆動によりハウジング２１がＭ２の位置まで下降して停止した状態を示している。このときコントローラ１０は間隔Ｌの値を変位計（図２の符号３１）から取得し、Ｌ１＋Ｘの値と比較する。ここでこの例では前述したように、Ｌ１は０．５ｍｍであり、Ｘは０．３ｍｍである。   When the various settings described with reference to FIG. 3 are completed, the actual heat caulking operation described with reference to FIG. 4 is started. In FIG. 4D, after the setting of the one member 51 and the other member 52 to be heat caulked, the operator depresses the start switch for instructing the start of the heat caulking work, and the motor 6 is driven. Thus, the housing 21 is lowered to the position M2 and stopped. At this time, the controller 10 acquires the value of the interval L from the displacement meter (reference numeral 31 in FIG. 2) and compares it with the value of L1 + X. In this example, as described above, L1 is 0.5 mm and X is 0.3 mm.

したがって、図４（ｄ）で描いたように、かしめ部上端と作用端７が熱かしめのためのほぼ正常な位置で当接している場合は、Ｌの値は０．８ｍｍ以下となり、コントローラ１０はこの比較結果を正常とみなして次の動作に入る。一方図４（ｄ′）で描いたように、かしめ部上端と作用端７が熱かしめのための正常な位置から大きくずれて当接している場合は、Ｌの値は０．８ｍｍよりも大きな値となる。この場合コントローラ１０はこの比較結果を異常と判断し、その後の熱かしめ動作を停止し、操作者等に対してアラームの表示をおこなう。 Therefore, as depicted in FIG. 4D, when the upper end of the caulking portion and the working end 7 are in contact with each other at a substantially normal position for heat caulking, the value of L becomes 0.8 mm or less, and the controller 10 Regards this comparison result as normal and enters the next operation. On the other hand, as illustrated in FIG. 4D ', when the upper end of the caulking portion and the working end 7 are in contact with a large deviation from the normal position for heat caulking, the value of L is larger than 0.8 mm. Value. In this case, the controller 10 determines that the comparison result is abnormal, stops the subsequent heat caulking operation, and displays an alarm to the operator or the like.

次に図４（ｅ）は、図４（ｄ）のように、かしめ部上端と作用端７が熱かしめのためのほぼ正常な位置で当接している場合においての次の動作を示している。このときモータ６は自動的に駆動してハウジング２１を更に下降させ、その高さ方向の位置がＭ１＋Ｌ１になったところで停止しその位置を保持する。ここでＭ１は図３（ｂ）で示した状態のハウジング２１の高さ方向の位置であり、これにＬ１（０．５ｍｍ）を加算したハウジング２１の高さ方向の位置は、作用端７が突起５１Ａを正常に潰しきった状態で間隔Ｌがゼロになる位置となっている。したがってこの状態での間隔ＬをＬ２とすると、Ｌ２は、作用端７が加熱を行いながら突起５１Ａを潰して下降すべきストロークであることがわかる。   Next, FIG. 4 (e) shows the next operation when the upper end of the caulking portion and the working end 7 are in contact with each other at a substantially normal position for heat caulking, as shown in FIG. 4 (d). . At this time, the motor 6 is automatically driven to further lower the housing 21, and stops when the position in the height direction becomes M1 + L1, and holds that position. Here, M1 is the position in the height direction of the housing 21 in the state shown in FIG. 3B, and the position in the height direction of the housing 21 obtained by adding L1 (0.5 mm) to the position of the working end 7 is It is a position where the interval L becomes zero in a state where the protrusion 51A is normally crushed. Accordingly, when the interval L in this state is L2, it can be seen that L2 is a stroke that should be lowered by crushing the protrusion 51A while the working end 7 is heating.

図４（ｅ）の状態でコントローラ１０はパルスヒート電源（図１の符号９）に出力の指令を発し、これに応じてパルスヒート電源９は熱電対（図２の符号７Ｃ）によるフィードバック制御を行いながら作用端７に通電し、作用端７に抵抗発熱をもたらす。その結果図４（ｆ）で示すように、突起５１Ａが前記抵抗発熱により軟化し、潰れるように変形しつつドーム型の凹所７Ｄの中に収まることで作用端７の下端が他方の部材５２に当接する。そしてこのとき大径部２６とハウジング２１との間隔Ｌはゼロとなるので、作用端７は、前述した押圧ばね２４の付勢力の設定値２０Ｎで、軟化した突起５１Ａを下方に向けて保持していることになる。そして、軟化した突起Ａが所定の硬度に戻るまで、通電を停止するだけか、あるいはこれに冷却風を吹き付けながらこの状態を保った後、作用端７を上方に移動させて待機位置に戻す。   In the state of FIG. 4 (e), the controller 10 issues an output command to the pulse heat power supply (reference numeral 9 in FIG. 1), and the pulse heat power supply 9 performs feedback control by the thermocouple (reference numeral 7C in FIG. 2) in response to this. While being performed, the working end 7 is energized to cause resistance heating to the working end 7. As a result, as shown in FIG. 4 (f), the protrusion 51A is softened by the resistance heat generation and is deformed so as to be crushed, and is fitted in the dome-shaped recess 7D, so that the lower end of the working end 7 becomes the other member 52. Abut. At this time, since the distance L between the large-diameter portion 26 and the housing 21 becomes zero, the working end 7 holds the softened protrusion 51A downward with the set value 20N of the biasing force of the pressing spring 24 described above. Will be. Then, the energization is only stopped until the softened protrusion A returns to a predetermined hardness, or after this state is maintained while cooling air is blown on the protrusion A, the working end 7 is moved upward to return to the standby position.

次に図５のフローチャートに基づいて、前述した実施形態の全体的な流れを説明する。まず、熱かしめ作業に際して装置に電源を投入する（Ｓ１）。次に、ワークの位置を故意にずらし、作用端７がかしめ部に当接せずに根元の近傍に当接するようにして、熱かしめ終了時点の作用端７の高さ方向の位置を取得し記憶する（Ｓ２）。次に、作用端７がかしめ部に当接した時点の作用端７の高さ方向の位置を取得し記憶する（Ｓ３）。次に、かしめ部の作用端７に対する水平方向の位置ずれを、作用端７の高さ方向の位置の変化に置き換えて、その許容値を操作者が装置に入力し記憶させる（Ｓ４）。   Next, the overall flow of the above-described embodiment will be described based on the flowchart of FIG. First, the apparatus is turned on during the heat caulking operation (S1). Next, the position of the work end 7 in the height direction at the end of heat caulking is obtained by deliberately shifting the position of the work so that the work end 7 does not contact the caulking portion but abutting near the root. Store (S2). Next, the position in the height direction of the action end 7 when the action end 7 comes into contact with the caulking portion is acquired and stored (S3). Next, the displacement in the horizontal direction of the caulking portion with respect to the working end 7 is replaced with a change in the position of the working end 7 in the height direction, and the allowable value is input and stored in the apparatus by the operator (S4).

ここで各種設定値が装置に記憶されたので、操作者は熱かしめ動作開始のスイッチを押下して、実際の熱かしめを開始する（Ｓ５）。次に熱かしめ装置は、作用端７を下降させてかしめ部に当接した時点で、この作用端７が熱かしめのための正常な高さの許容範囲に入るか否かを判定する（Ｓ６）。ここで前記許容範囲を上回っていた場合、その後の動作を停止してアラームを表示する（Ｓ７）。これを知った操作者はかしめ部の位置を修正して熱かしめ作業を再開する。またここで前記許容範囲内であった場合は、加熱と加圧を開始して熱かしめが行なわれる（Ｓ８）。１回の熱かしめが終了すると装置は待機位置に戻り、同一形状の熱かしめの対象が複数ある場合はＳ５（熱かしめ開始）まで戻って前述と同じ作業が繰返される。   Here, since various setting values are stored in the apparatus, the operator depresses the heat caulking operation start switch to start actual heat caulking (S5). Next, the heat caulking device determines whether or not the working end 7 falls within a normal height allowable range for heat caulking when the working end 7 is lowered and comes into contact with the caulking portion (S6). ). If the allowable range is exceeded, the subsequent operation is stopped and an alarm is displayed (S7). The operator who knows this corrects the position of the caulking part and resumes the caulking work. If it is within the allowable range, heating and pressurization are started and heat caulking is performed (S8). When one heat caulking is completed, the apparatus returns to the standby position, and when there are a plurality of heat caulking objects having the same shape, the apparatus returns to S5 (starting heat caulking) and repeats the same operation as described above.
