続いて、図〜図12を参照して、仕切部材可動機構40を含む蓋体31の組立例について説明する。この例では、図12に示す11本のスリット41が下部板304の所定の位置に開口され、スリット41毎に図11に示したラビリンス部43を通すようになされる。全てのラビリンス部43は摺動基板44に共通して取り付ける。その際にラビリンス部43は列単位毎に摺動基板44のスリット49に挿入する。ラビリンス部43は、その一端が下部板304のスリット41毎に通されて熱処理部20の側に吊設して(垂れ下がる状態で)使用される。
Subsequently, an assembly example of the lid 31 including the partition member movable mechanism 40 will be described with reference to FIGS. 9 to 12. In this example, eleven slits 41 shown in FIG. 12 are opened at predetermined positions in the lower plate 304, and the labyrinth portion 43 shown in FIG . All the labyrinth parts 43 are commonly attached to the sliding substrate 44. At this time, the labyrinth portion 43 is inserted into the slit 49 of the sliding substrate 44 for each row. One end of the labyrinth portion 43 is passed through each slit 41 of the lower plate 304, and the labyrinth portion 43 is used by hanging on the side of the heat treatment portion 20 (in a hanging state).

続いて、図14及び図15を参照して、第3の実施例として両端ガス供給機構70の構成例について説明する。図14に示す両端ガス供給機構70は、図1に示した噴流はんだ付け装置100に備えられる。両端ガス供給機構70は、図1に示した1組のガス供給部71,72と、図14に示すノズル管路75と、拡散部材76a,76bから構成される。
Subsequently, a configuration example of the both-end gas supply mechanism 70 will be described as a third embodiment with reference to FIGS. 14 and 15. The double-end gas supply mechanism 70 shown in FIG. 14 is included in the jet soldering apparatus 100 shown in FIG. The two-end gas supply mechanism 70 includes the pair of gas supply units 71 and 72 shown in FIG. 1, the nozzle pipe 75 shown in FIG. 14, and the diffusion members 76a and 76b.

この例で、噴流はんだ槽60上の周囲縁部には拡散部材76a,76bが備えられ、ノズル管路75から噴出される窒素ガスを噴流はんだ槽60上の周囲縁部に拡散するようになされる。拡散部材76a,76bは、チャンバー50の開口部50の下方に配置される。
In this example, diffusion members 76 a and 76 b are provided on the peripheral edge on the jet solder tank 60 so as to diffuse the nitrogen gas ejected from the nozzle channel 75 to the peripheral edge on the jet solder tank 60. Ru. Diffusing member 76a, 76b is disposed in the lower opening 50 2 in the chamber 50.

この例では、管路接続部702に隣接して管路接続部703がアングル架台77に取り付けられる。管路接続部703には、窒素ガス検出用の開放管路78が接続される。開放管路78は噴流はんだ槽60上の窒素ガスの濃度を測定するために設けられる。開放管路78は先端がU字部位78aを成し、このU字部位78aは窒素ガスを取り込む開放口708を有している。開放口708は、プリント基板1の搬送方向であって、その下流側に向くように設定されている。この開放口708を下流側に向くようにしたのは、拡散部材76a内の窒素ガスをより正確に測定することと、開放口708に溶融はんだ7が入り込まないようにするためである。
In this example, a conduit connection 703 is attached to the angle mount 77 adjacent to the conduit connection 702. An open pipeline 78 for nitrogen gas detection is connected to the pipeline connection section 703. An open line 78 is provided to measure the concentration of nitrogen gas on the jet solder tank 60. The open conduit 78 has a U-shaped portion 78a at its tip end, and the U-shaped portion 78a has an open port 708 for taking in nitrogen gas. The opening 708 is set to face the downstream side in the transport direction of the printed circuit board 1. The reason why the opening 708 is directed to the downstream side is to more accurately measure the nitrogen gas in the diffusion member 76 a and to prevent the molten solder 7 from entering the opening 708.

また、図中の分離壁部79は所定の厚みを有した板金部材から構成され、ノズル管路75の水平部分75c(図15参照)のほぼ中心部位に対向する位置であって、チャンバー50の下方の仕切壁部58から突出するように設けられる。分離壁部79は、ノズル管路45の左側の4個のガス噴出口704から噴出された窒素ガスの拡散領域と、右側の4個のガス噴出口704から噴出された窒素ガスの拡散領域とを分離(画定)するように機能する。
Further, the separation wall 79 in the figure is formed of a sheet metal member having a predetermined thickness, and is a position facing substantially the central portion of the horizontal portion 75c (see FIG. 15) of the nozzle channel 75 . It is provided to project from the lower partition wall 58. The separation wall portion 79 includes a diffusion region of nitrogen gas jetted from the four gas jets 704 on the left side of the nozzle channel 45 and a diffusion region of nitrogen gas jetted from the four gas jets 704 on the right side. Function to separate (define)

続いて、図20〜図23を参照して、第4の実施例としての蓋体ユニット80の構成例及びその機能例について説明する。図20に示す蓋体ユニット80は噴流はんだ付け装置100のチャンバー50上に取り付けられる。この例では、図16に示した拡散ノズル51,52を内包するチャンバー50の上方側に、蓋体ユニット80が取り付けられる。蓋体ユニット80は、スリット付きの筺体構造(扁平筺体空間)の本体部84を有している。
Subsequently, a configuration example of the lid unit 80 according to the fourth embodiment and a function example thereof will be described with reference to FIGS. The lid unit 80 shown in FIG. 20 is mounted on the chamber 50 of the jet soldering apparatus 100. In this example, a lid unit 80 is attached to the upper side of the chamber 50 containing the diffusion nozzles 51 and 52 shown in FIG . The lid unit 80 has a main body 84 of a slit-shaped housing structure (flat housing space).

雰囲気送入口801にはL状の吸気管88が接続され、フラックスヒュームを除去した窒素ガスを含む雰囲気が供給される。雰囲気排出口802にもL状の排気管89が接続され、フラックスヒュームを含んだ雰囲気が排出される。このように吸気管88,89を蓋体ユニット80の側面に配置したことで、管路部材等が垂直方向へ延在する事態が避けられ、図1に示した噴流はんだ装置100の全体高さを低く設計できるようになった。
An L-shaped intake pipe 88 is connected to the atmosphere feed port 801, and an atmosphere containing nitrogen gas from which flux fumes have been removed is supplied. An L-shaped exhaust pipe 89 is also connected to the atmosphere exhaust port 802, and an atmosphere including flux fumes is exhausted. By arranging the intake pipes 88 and 89 on the side surface of the lid unit 80 in this manner, a situation in which the channel members etc. extend in the vertical direction can be avoided, and the entire height of the jet soldering apparatus 100 shown in FIG. It became possible to design low.

モニタ16は噴流はんだ付け処理に係る設定画面等を表示データD16に基づいて表示する。モニタ16には、例えば、タッチパネル付きの液晶表示装置が使用される。タッチパネルは、入力部64の一部を構成する。表示データD16には、プリント基板1にはんだ付けされる電子部品の高さ情報や、プリント基板1にはんだ付けされる電子部品の実装分布情報等が含まれる。この他に、表示データD16には、電子部品がはんだ付けされる基板の枚数情報、はんだ付け処理条件を示す設定情報等である。
The monitor 16 displays a setting screen and the like related to the jet soldering process based on the display data D16. As the monitor 16, for example, a liquid crystal display device with a touch panel is used. The touch panel constitutes a part of the input unit 64. The display data D16 includes height information of the electronic component to be soldered to the printed circuit board 1, information on mounting distribution of the electronic component to be soldered to the printed circuit board 1, and the like.
