Abstract

<P>PROBLEM TO BE SOLVED: To prevent a burr from occurring on caulking and holding a lens at a lens flame by heating and pressing a caulking part arranged at a plastic made lens flame. <P>SOLUTION: The lens flame 32 made of a plastic material where a lens is held with a lens holding member 34 is mounted at a fixing tool. A heating and caulking apparatus 30 makes positioned by pressing the lens 31 with a lens pressing tool 41, a heater unit 42 heated in a given temperature range is descended from a turnout position to a caulking position. Accompanied with the descendant, a regulation member 74 is descended under opposing an opposed face 73 to an outer periphery face 32a. A pressing face 72 heats and presses a caulking part 35. The caulking part 35 is inclined to an optical axis direction of the lens 31 along a pressing face 72. The caulking part 35 is chilled and solidified and holds the lens 31 under caulking. Thus, since the regulation member 74 regulates the caulking part 35 deformed by heat to protrude to the out side of the outer periphery face 32a, the occurrence of a burr can be prevented. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

プラスチック製のレンズ枠にレンズをカシメ保持させる熱カシメ装置に関するものである。   The present invention relates to a heat caulking device for caulking and holding a lens in a plastic lens frame.

プラスチック製のレンズ枠にレンズをカシメ保持させるカシメ装置が知られている。図７は従来の熱カシメ装置の一例を示す。作業者はレンズ枠１０の一方の端面開口１１からレンズ１２を挿入する。そして、このレンズ枠１０を熱カシメ装置に設けられた固定治具（図示せず）に固定する。固定されたレンズ枠１０の上方には、レンズ押え治具１５とヒータヘッド１６が設けられており、まずレンズ押え治具１５を下降させて固定パッド１７でレンズ１２をレンズ枠１０内で下方に押圧する。そして、ヒータ（図示せず）によって加熱されたヒータヘッド１６を下降させる。これにより、端部開口１１の周囲に設けられたカシメ部１８が、ヒータヘッド１６の加圧面１９により、加熱および加圧されて熱変形され、レンズ１２はレンズ枠１０にカシメ保持される。   There is known a caulking device that caulks and holds a lens on a plastic lens frame. FIG. 7 shows an example of a conventional heat caulking device. The operator inserts the lens 12 from one end face opening 11 of the lens frame 10. Then, the lens frame 10 is fixed to a fixing jig (not shown) provided in the heat caulking device. Above the fixed lens frame 10, a lens pressing jig 15 and a heater head 16 are provided. First, the lens pressing jig 15 is lowered and the lens 12 is moved downward in the lens frame 10 by a fixed pad 17. Press. Then, the heater head 16 heated by a heater (not shown) is lowered. Thereby, the crimping portion 18 provided around the end opening 11 is heated and pressurized by the pressure surface 19 of the heater head 16 and thermally deformed, and the lens 12 is crimped and held on the lens frame 10.

また、特許文献１には、カシメ加工治具（ヒータヘッド）によってレンズ枠端縁（カシメ部）を加熱および加圧した際に、レンズ枠端縁と加圧面の引き離しが容易で、かつ加圧後のカシメ部が平滑となるカシメ加工装置が提案されている。
特許第３６９４５８６号 Further, in Patent Document 1, when the lens frame edge (caulking portion) is heated and pressed by a crimping jig (heater head), the lens frame edge and the pressing surface are easily separated and pressed. A caulking processing device has been proposed in which the subsequent caulking portion becomes smooth.
Japanese Patent No. 3694586

しかしながら、図６に示すヒータヘッド１６や、特許文献１に記載のカシメ加工治具を用いてカシメ部１８（レンズ枠端縁）の加熱および加圧を行った場合、加熱温度および加圧力が大きすぎると加圧面１９に沿って熱変形したカシメ部１８の一部がレンズ枠１０の外周面１０ａより外側に大量に突出する。つまり、図中二点鎖線で示すようにバリ２０が発生する。加圧面１９でカシメ部１６を加熱、加圧を行って、外周面１０ａの外側に熱変形したカシメ部１６が僅かにはみ出す場合にはなんら問題は無いが、大量にはみ出したバリ２０は、レンズ枠１０をレンズ鏡筒やカメラに組み込む際の障害となるばかりでなく、レンズ枠１０を組み込んだ際にバリが剥離し、ゴミとして撮影した画像に移り込むという問題もある。また、加工したレンズ枠１０を検査してバリを取り除く作業を行うことは、作業効率を悪くする。   However, when the caulking portion 18 (lens frame edge) is heated and pressurized using the heater head 16 shown in FIG. 6 or the caulking jig described in Patent Document 1, the heating temperature and the applied pressure are large. If too much, a part of the crimped portion 18 that is thermally deformed along the pressing surface 19 protrudes in a large amount outside the outer peripheral surface 10 a of the lens frame 10. That is, the burr 20 is generated as shown by the two-dot chain line in the figure. There is no problem when the crimping portion 16 is heated and pressurized by the pressing surface 19 and the thermally deformed crimping portion 16 slightly protrudes outside the outer peripheral surface 10a. Not only does the frame 10 become a hindrance when assembling the lens barrel or camera, but there is also a problem that when the lens frame 10 is assembled, the burrs are peeled off and transferred to an image taken as dust. In addition, inspecting the processed lens frame 10 to remove burrs deteriorates work efficiency.

本発明の熱カシメ装置は、上記問題を解決するためになされたものであり、バリを発生させずにプラスチック製のレンズ枠を熱変形させて、レンズをレンズ枠にカシメ保持させる熱カシメ装置を提供することを目的とする。   The thermal caulking device of the present invention is made to solve the above-mentioned problem, and is a thermal caulking device that heat-deforms a plastic lens frame without generating burrs and holds the lens to the lens frame. The purpose is to provide.

上記問題を解決するために、本発明のカシメ装置は、一方の端部開口からレンズが挿入されたプラスチック製のレンズ枠に対して、ヒータを有したヒータヘッドを昇降させ、その降下時に前記端部開口の周囲に設けられたカシメ部を加熱および加圧して熱変形させ、前記レンズを前記レンズ枠にカシメ保持させる熱カシメ装置において、前記ヒータヘッドは、前記カシメ部を加熱および加圧する加圧部と、降下時に前記レンズ枠の外周面に沿って配置され、熱変形された前記カシメ部の前記外周面より外側へのはみ出しを規制するはみ出し規制部とを備えたことを特徴とするものである。   In order to solve the above-described problem, the caulking device according to the present invention raises and lowers a heater head having a heater with respect to a plastic lens frame into which a lens is inserted from one end opening. In a thermal caulking device that heats and pressurizes a caulking part provided around the opening of the part and thermally deforms and holds the lens in the lens frame, the heater head pressurizes and heats the caulking part And a protrusion restricting portion that is disposed along the outer peripheral surface of the lens frame when lowered and restricts the protrusion of the caulking portion that is thermally deformed outward from the outer peripheral surface. is there.

また、前記はみ出し規制部は、前記ヒータヘッドの降下時に前記外周面と所定の間隔で対向する対向面を備えていることが好ましい。また、前記カシメ部は、前記端部開口の周囲に所定の間隔で複数設けられていることが好ましい。   Moreover, it is preferable that the said protrusion control part is provided with the opposing surface which opposes the said outer peripheral surface with a predetermined space | interval when the said heater head descend | falls. Moreover, it is preferable that a plurality of the crimping portions are provided around the end opening at a predetermined interval.

以上のように、本発明のカシメ装置によれば、一方の端部開口からレンズが挿入されたプラスチック製のレンズ枠に対して、ヒータを有したヒータヘッドを昇降させ、その降下時に端部開口の周囲に設けられたカシメ部を加熱および加圧して熱変形させ、レンズをレンズ枠にカシメ保持させる熱カシメ装置において、ヒータヘッドは、カシメ部を加熱および加圧する加圧部と、降下時にレンズ枠の外周面に沿って配置され、熱変形されたカシメ部の外周面より外側へのはみ出しを規制するはみ出し規制部とを備えたので、熱変形されたカシメ部がレンズ枠の外側に突出する、所謂バリが発生することを防ぐことができる。これにより、レンズ枠からバリを取り除く作業を行う必要がなくなるので、作業性が向上する。また、バリの発生が防止されるので、レンズ鏡筒やカメラに組み込む際の嵌合性が向上する。   As described above, according to the caulking device of the present invention, the heater head having the heater is raised and lowered with respect to the plastic lens frame into which the lens is inserted from one end opening, and the end opening is opened when the head is lowered. In the thermal caulking device that heats and pressurizes the caulking portion provided around the lens to thermally deform the lens and holds the lens in the lens frame, the heater head includes a pressurizing portion that heats and pressurizes the caulking portion, and a lens when lowered. Since it is provided along the outer peripheral surface of the frame and has an overhanging restricting portion that restricts the outer surface of the caulking portion that is thermally deformed from protruding outward, the caulking portion that is thermally deformed protrudes to the outside of the lens frame. It is possible to prevent so-called burrs from occurring. This eliminates the need to remove the burrs from the lens frame, improving workability. Further, since the generation of burrs is prevented, the fitting property when incorporated in a lens barrel or a camera is improved.

図１は、本発明を用いた熱カシメ装置の概略図である。この熱カシメ装置３０は、銀塩カメラやデジタルカメラ、デジタルビデオカメラなどに組み込まれる撮影光学系を構成するレンズ３１をレンズ枠３２にカシメ保持させる。   FIG. 1 is a schematic view of a thermal caulking apparatus using the present invention. This thermal crimping device 30 causes a lens frame 32 to crimp and hold a lens 31 constituting a photographing optical system incorporated in a silver salt camera, a digital camera, a digital video camera, or the like.

図２に示すように、レンズ枠３２は、プラスチック材料で略円筒形状に形成されており、その一方の端部開口３３には、レンズ３１を挿入する凹状のレンズ保持部３４が形成されている。レンズ保持部３４は、レンズ３１を光軸方向で位置決めする。そして、端部開口３３の周囲には、所定間隔で突起状のカシメ部３５が４つ設けられている。カシメ部３５は、レンズ保持部３４に挿入されたレンズ３１周縁の上面よりいずれも突出している。なお、端部開口３３の周囲に突起状のカシメ部３５が４つ設けられているが、これに限らず、端部開口３３の周囲に帯状のカシメ部を、レンズ３１を囲むように設けてもよい。大径のレンズ３１の場合には、レンズ３１の保持力を向上させるために、端部開口３３の周囲にはレンズ３１の外周を全て囲むようにカシメ部を設けられることが好ましい。また、レンズ３１の周縁上面の位置よりも突出するカシメ部３５の突出量は、レンズ３１の大きさによって適宜に設定することが好ましい。   As shown in FIG. 2, the lens frame 32 is formed of a plastic material in a substantially cylindrical shape, and a concave lens holding portion 34 into which the lens 31 is inserted is formed in one end opening 33 thereof. . The lens holding unit 34 positions the lens 31 in the optical axis direction. Around the end opening 33, four protruding caulking portions 35 are provided at predetermined intervals. The caulking portion 35 protrudes from the upper surface of the periphery of the lens 31 inserted into the lens holding portion 34. In addition, although four protrusion-shaped caulking portions 35 are provided around the end opening 33, the present invention is not limited to this, and a band-like caulking portion is provided around the end opening 33 so as to surround the lens 31. Also good. In the case of the large-diameter lens 31, it is preferable that a caulking portion is provided around the end opening 33 so as to surround the entire outer periphery of the lens 31 in order to improve the holding force of the lens 31. Further, it is preferable that the protruding amount of the caulking portion 35 protruding beyond the position of the upper surface of the peripheral edge of the lens 31 is appropriately set according to the size of the lens 31.

図１に示すように、熱カシメ装置３０は、固定治具４０、レンズ押え部材４１、ヒータヘッド４２、第１エアシリンダ４３、第２エアシリンダ４４、ブロアー４５などから構成されている。図２にも示すように、固定治具４０は、熱カシメ装置３０の本体に設けられた台座４８の上に固定される。この時、固定治具４０は台座４８に設けられた突起４９を位置決め穴５０に挿入し、固定治具４０の位置決めを行ってからビス５２によって固定される。また、固定治具４０の上面には、レンズ枠３２が装着される装着部５３が設けられている。装着部５３は、レンズ枠３２の他方の端部（カシメ部３５が設けられていない方の端部）の外形と略同形状をしている。これより、レンズ枠３２は装着部５３に嵌合状態で装着される。   As shown in FIG. 1, the heat caulking device 30 includes a fixing jig 40, a lens pressing member 41, a heater head 42, a first air cylinder 43, a second air cylinder 44, a blower 45, and the like. As shown also in FIG. 2, the fixing jig 40 is fixed on a pedestal 48 provided in the main body of the thermal caulking device 30. At this time, the fixing jig 40 is fixed by the screw 52 after the protrusion 49 provided on the base 48 is inserted into the positioning hole 50 and the fixing jig 40 is positioned. Further, a mounting portion 53 to which the lens frame 32 is mounted is provided on the upper surface of the fixing jig 40. The mounting portion 53 has substantially the same shape as the other end portion of the lens frame 32 (the end portion where the caulking portion 35 is not provided). Accordingly, the lens frame 32 is attached to the attachment portion 53 in a fitted state.

図１に示すレンズ押え部材４１は、図示しないガイドに沿って上下方向に移動し、レンズ保持部３４に嵌め込まれたレンズ３１を下方向に押圧するものである。レンズ押え部材４１は、シャフト５５、固定パッド５６から構成されており、シャフト５５の一方の端部には第１エアシリンダ４３のロッド（図示せず）が接続されており、他方の端部には固定パッド５６が設けられている。第１エアシリンダ４３はロッドを伸縮させることにより、固定パッド５６でレンズ３１を下方に押圧する押圧位置と固定パッド５６をレンズ３１の上方で待機させる待機位置との間でレンズ押え部材４１を昇降させる。   A lens pressing member 41 shown in FIG. 1 moves in a vertical direction along a guide (not shown), and presses the lens 31 fitted in the lens holding portion 34 downward. The lens pressing member 41 includes a shaft 55 and a fixed pad 56. A rod (not shown) of the first air cylinder 43 is connected to one end portion of the shaft 55, and the other end portion. A fixed pad 56 is provided. The first air cylinder 43 extends and retracts the rod, thereby moving the lens pressing member 41 up and down between a pressing position where the fixed pad 56 presses the lens 31 downward and a standby position where the fixed pad 56 waits above the lens 31. Let

固定パッド５６は、例えば耐熱性を有し、レンズ３１を傷つけ難いテクトロン（登録商標）などの材質を使用する。また、シャフト５５と固定パッド５６との間には、捩りバネ５７が設けられている。レンズ押え部材４１を待機位置から押圧位置に降下させ、固定パッド５６がレンズ３１に当接すると固定パッド５６が上方に押し上げられるので、レンズ３１には固定パッド５６を介して捩りバネ５７の付勢力が付与される。よって、レンズ３１は固定パッド５６によって下方に押圧される。   The fixed pad 56 is made of, for example, a material such as Tektron (registered trademark) which has heat resistance and hardly damages the lens 31. A torsion spring 57 is provided between the shaft 55 and the fixed pad 56. When the lens pressing member 41 is lowered from the standby position to the pressing position and the fixed pad 56 comes into contact with the lens 31, the fixed pad 56 is pushed upward, so that the biasing force of the torsion spring 57 is applied to the lens 31 via the fixed pad 56. Is granted. Therefore, the lens 31 is pressed downward by the fixed pad 56.

また、シャフト５５の中央部で、かつシャフト５５の一方の端部から固定パッド５６の近傍にかけて誘導穴６０が形成されている。一方の端部に形成された誘導穴６０には、誘導穴６０にエアーを供給するブロアー４５が接続されている。さらに、固定パッド５６の上方で、かつシャフト５５の外周には４つのエアー供給孔６１が装着部５３に装着されたレンズ枠３２のカシメ部３５に対向する位置に形成されており、このエアー供給孔６１は誘導穴６０と連通している。ブロアー４５から供給されたエアーは、図６の矢線Ａに示すように、誘導穴６０を通って各エアー供給孔６１からカシメ部３５に向かって放射状に噴射される。なお、カシメ部３５が端部開口３３の周囲に帯状に設けられている場合には、このカシメ部３５の全体にエアーが噴射されるように、シャフト５５の外周に等間隔で複数のエアー供給孔６１を設けることが好ましい。これにより、エアー供給孔６０から噴射されるエアーは、シャフト５５を中心に放射状に噴射される。   In addition, a guide hole 60 is formed at the center of the shaft 55 and from one end of the shaft 55 to the vicinity of the fixed pad 56. A blower 45 that supplies air to the guide hole 60 is connected to the guide hole 60 formed at one end. Furthermore, four air supply holes 61 are formed above the fixed pad 56 and on the outer periphery of the shaft 55 at positions facing the caulking portion 35 of the lens frame 32 attached to the attachment portion 53. The hole 61 communicates with the guide hole 60. The air supplied from the blower 45 is ejected radially from each air supply hole 61 toward the caulking portion 35 through the guide hole 60 as indicated by an arrow A in FIG. When the caulking portion 35 is provided in the form of a band around the end opening 33, a plurality of air supplies are supplied to the outer periphery of the shaft 55 at equal intervals so that air is jetted to the entire caulking portion 35. It is preferable to provide the hole 61. Thereby, the air injected from the air supply hole 60 is injected radially around the shaft 55.

ヒータヘッド４２は、固定治具４０に嵌め込まれたレンズ枠３２の上方に配置された退避位置から、カシメ部３５を加熱および加圧するカシメ位置に移動させることで、カシメ部３５を熱変形させて、レンズ３１をレンズ枠３２にカシメ保持させる。ヒータヘッド４２は、加圧部材６３、ベース６４、バンドヒータ６５から構成されている。   The heater head 42 thermally deforms the caulking part 35 by moving the caulking part 35 from the retracted position disposed above the lens frame 32 fitted in the fixing jig 40 to the caulking position where the caulking part 35 is heated and pressurized. The lens 31 is caulked and held on the lens frame 32. The heater head 42 includes a pressure member 63, a base 64, and a band heater 65.

図３にも示すように、加圧部材６３は、例えば炭素工具鋼が用いられており、円筒形状のボス部６６およびフランジ部６７から構成されている。加圧部材６３は、ベース６４の下面にフランジ部６７を当接させてビス７０で固定されている（図１参照）。そして、ボス部６６にはレンズ枠３２の外径よりやや大きい円形開口７１が形成されており、この円形開口７１はベース６４の方向（上方）に近づくに従って、その直径が小さくなるすり鉢状の加圧面７２が形成されている。加圧部である加圧面７２は、ヒータヘッド４２の降下時にカシメ部３５を加熱および加圧する。さらに、加圧部材６３には円形開口７１の周縁から連設された規制部７４が設けられている。規制部７４は、ヒータヘッド４２を退避位置からカシメ位置に降下させる時に、レンズ枠３２の外周面３２ａに沿うように配置され、外周面３２ａと所定間隔を保って対向する対向面７３を備えている。この対向面７３は加圧面７２の端部から垂下しており、その長さはカシメ部３５より長い。   As shown in FIG. 3, the pressurizing member 63 is made of, for example, carbon tool steel and includes a cylindrical boss portion 66 and a flange portion 67. The pressure member 63 is fixed with screws 70 with a flange portion 67 abutting against the lower surface of the base 64 (see FIG. 1). The boss portion 66 is formed with a circular opening 71 that is slightly larger than the outer diameter of the lens frame 32. The circular opening 71 has a mortar-like shape that decreases in diameter toward the base 64 (upward). A pressure surface 72 is formed. The pressurizing surface 72 which is a pressurizing unit heats and pressurizes the crimping unit 35 when the heater head 42 is lowered. Further, the pressing member 63 is provided with a restricting portion 74 provided continuously from the periphery of the circular opening 71. The restricting portion 74 includes an opposing surface 73 that is disposed along the outer peripheral surface 32a of the lens frame 32 and faces the outer peripheral surface 32a at a predetermined interval when the heater head 42 is lowered from the retracted position to the caulking position. Yes. The facing surface 73 hangs from the end of the pressing surface 72, and its length is longer than the crimping portion 35.

また、図１に示すベース６４にはバンドヒータ６５が設けられている。バンドヒータ６５は略円筒形状をしており、この内径部分にはベース６３が嵌め込まれている。バンドヒータ６５は、プラスチック材料を溶融する所定温度範囲（約２００前後℃）にまでヒータヘッド４２を加熱する。このバンドヒータ６５はサーモスタットなどを用いた自動温度調整装置に接続されており、ヒータヘッド４２は常に所定温度範囲で維持されている。   Further, a band heater 65 is provided on the base 64 shown in FIG. The band heater 65 has a substantially cylindrical shape, and a base 63 is fitted into this inner diameter portion. The band heater 65 heats the heater head 42 to a predetermined temperature range (about 200 ° C.) at which the plastic material is melted. The band heater 65 is connected to an automatic temperature control device using a thermostat or the like, and the heater head 42 is always maintained in a predetermined temperature range.

さらに、ベース６４には図示しない断熱部材を介して第２エアシリンダ４４のロッドが接続されている。この第２エアシリンダ４４はロッドを伸縮させることにより、レンズ枠３２の上方に配置された退避位置と、加圧面７２でカシメ部３５を加熱および加圧するカシメ位置との間でヒータヘッド４２を昇降させる。   Further, the rod of the second air cylinder 44 is connected to the base 64 via a heat insulating member (not shown). The second air cylinder 44 raises and lowers the heater head 42 between a retracted position disposed above the lens frame 32 and a caulking position for heating and pressurizing the caulking portion 35 with the pressing surface 72 by extending and contracting the rod. Let

また、加圧部材６３とベース６４には、その中心部にレンズ押え部材４１を挿通させる挿通孔７７が形成されている。レンズ押え部材４１は、この挿通孔７７を介して押圧位置と待機位置の間で昇降する。なお、ヒータヘッド４２からの放熱を防止し、ヒータヘッド４２を効率よく加熱するために挿通孔７７はできるだけ小さい方が好ましい。   Further, the pressure member 63 and the base 64 are formed with an insertion hole 77 through which the lens pressing member 41 is inserted at the center thereof. The lens pressing member 41 moves up and down between the pressing position and the standby position through the insertion hole 77. In order to prevent heat dissipation from the heater head 42 and to efficiently heat the heater head 42, the insertion hole 77 is preferably as small as possible.

次に、本発明の熱カシメ装置３０でカシメ部３５を熱変形させて、レンズ３１をレンズ枠３２にカシメ保持させる流れを説明する。図１に示すように、レンズ枠３２の一方の端部開口３３からレンズ保持部３４にレンズ３１を挿入し、固定治具４０にレンズ枠３２を装着すると、図４に示すように、レンズ押え部材４１が待機位置から押圧位置に降下する。これにより、固定パッド５６は捩りバネ５７の付勢力によってレンズ３１をレンズ保持部３４に押圧する。従って、レンズ３１はレンズ保持部３４内で位置決めされるとともに、レンズ枠３２も固定治具４０の装着部５３（図２参照）に押圧され、レンズ枠３２およびレンズ３１の位置がずれることを防止できる。   Next, a flow of causing the lens 31 to be caulked and held by the lens frame 32 by thermally deforming the caulking portion 35 with the heat caulking device 30 of the present invention will be described. As shown in FIG. 1, when the lens 31 is inserted into the lens holding portion 34 from one end opening 33 of the lens frame 32 and the lens frame 32 is attached to the fixing jig 40, as shown in FIG. The member 41 descends from the standby position to the pressing position. As a result, the fixed pad 56 presses the lens 31 against the lens holding portion 34 by the urging force of the torsion spring 57. Therefore, the lens 31 is positioned in the lens holding portion 34, and the lens frame 32 is also pressed by the mounting portion 53 (see FIG. 2) of the fixing jig 40 to prevent the positions of the lens frame 32 and the lens 31 from shifting. it can.

次に、図５に示すように、レンズ押え部材４１でレンズ３１を押圧したままの状態で、ヒータヘッド４２を退避位置からカシメ位置に上昇させる。この時、規制部７４はその対向面７３をレンズ枠３２の外周面３２ａに対向させながらカシメ位置に向かって降下する。そして、ヒータヘッド４２がカシメ位置まで降下すると、カシメ部３５は加圧面７２で加熱、溶融されながら加圧される。これにより、レンズ３１は熱変形されたカシメ部３５によってレンズ枠３２にカシメ保持される。この時、外周面３２ａと規制部７４の対向面７３は所定の間隔で対向しているので、熱変形されたカシメ部３５が外周面３２ａより外側に大量にはみ出ることはない。よって、カシメ部３５を熱変形させてレンズ３１をカシメ保持させてもバリが発生することを防止できる。なお、熱変形したカシメ部３５はレンズ３１の有効口径の外側でレンズ３１をカシメ保持している。   Next, as shown in FIG. 5, the heater head 42 is raised from the retracted position to the crimped position while the lens 31 is being pressed by the lens pressing member 41. At this time, the restricting portion 74 descends toward the caulking position with the facing surface 73 facing the outer peripheral surface 32 a of the lens frame 32. When the heater head 42 is lowered to the caulking position, the caulking portion 35 is pressed while being heated and melted by the pressing surface 72. As a result, the lens 31 is caulked and held on the lens frame 32 by the caulking portion 35 that is thermally deformed. At this time, since the outer peripheral surface 32a and the opposing surface 73 of the restricting portion 74 are opposed to each other at a predetermined interval, the caulking portion 35 that is thermally deformed does not protrude in a large amount outside the outer peripheral surface 32a. Therefore, even if the caulking portion 35 is thermally deformed and the lens 31 is caulked and held, the occurrence of burrs can be prevented. The caulking portion 35 that has been thermally deformed holds the lens 31 by caulking outside the effective aperture of the lens 31.

そして、ヒータヘッド４２をカシメ位置まで降下さ、カシメ部３５の加熱および加圧が終了すると、図６に示すように、ヒータヘッド４２はカシメ位置から退避位置に上昇する。ヒータヘッド４２が退避位置に上昇すると、ブロアー４５から誘導穴６０にエアーが供給される。誘導穴６０に供給されたエアーは、図中矢線Ａで示すように、各エアー供給孔６１から熱変形されたカシメ部３５に向かって噴射される。これにより、加熱、溶融されたカシメ部３５が冷却されて、溶融したカシメ部３５が固化することで確実にレンズ３１をカシメ保持する。そして、カシメ部３５を十分に冷却した後は、図１に示すように、レンズ押え部材４１は押圧位置から待機位置に上昇する。これにより、レンズ３１をカシメ保持したレンズ枠３２が完成し、このレンズ枠３２は次の工程に搬送される。   Then, when the heater head 42 is lowered to the caulking position and heating and pressurization of the caulking portion 35 are completed, the heater head 42 is raised from the caulking position to the retracted position as shown in FIG. When the heater head 42 is raised to the retracted position, air is supplied from the blower 45 to the guide hole 60. The air supplied to the guide hole 60 is jetted from the air supply holes 61 toward the crimped portion 35 that is thermally deformed, as indicated by the arrow A in the figure. As a result, the heated and melted caulking portion 35 is cooled, and the melted caulking portion 35 is solidified to securely hold the lens 31 by caulking. Then, after the caulking portion 35 is sufficiently cooled, as shown in FIG. 1, the lens pressing member 41 rises from the pressing position to the standby position. Thereby, a lens frame 32 holding the lens 31 by crimping is completed, and the lens frame 32 is conveyed to the next step.

なお、上記実施形態では、自動温度調節装置を用いてバンドヒータ６５による加熱の制御を行い、ヒータヘッド４２を常に所定温度に保っていたが、これに限らず、加圧面７２でカシメ部３５を加圧するときに、瞬間的にヒータヘッド４２を所定温度に加熱する瞬間加熱型の熱カシメ装置３０を用いてもよい。また、ヒータヘッド４２にバンドヒータ６５を設けたが、加圧部材６３やベース６４に埋め込むタイプのヒータなどを用いてもよい。   In the above-described embodiment, the heating by the band heater 65 is controlled by using the automatic temperature control device, and the heater head 42 is always kept at a predetermined temperature. An instantaneous heating type heat caulking device 30 that instantaneously heats the heater head 42 to a predetermined temperature when pressurizing may be used. Further, although the band heater 65 is provided in the heater head 42, a heater embedded in the pressure member 63 or the base 64 may be used.

なお、本発明の熱カシメ装置２では、レンズの大きさや、カシメ部３５の形状、寸法に応じた加圧部材を複数用意し、ヒータヘッドの加圧部材を交換するだけで、複数種類のレンズをそのレンズに対応したレンズ枠にカシメ保持させることができる。   In the thermal caulking device 2 of the present invention, a plurality of types of lenses can be obtained simply by preparing a plurality of pressure members according to the size of the lens, the shape and size of the caulking portion 35, and replacing the pressure member of the heater head. Can be caulked and held in a lens frame corresponding to the lens.

また、上記実施形態では、円筒形状のレンズ枠を用いて説明したが、レンズ枠の形状はこれに限るものではなく、直方体形状のものであってもよい。   In the above embodiment, the cylindrical lens frame has been described. However, the shape of the lens frame is not limited to this, and may be a rectangular parallelepiped shape.
