平搬送型コンベヤに関するものである。[Industrial Application Field] The present invention relates to a horizontal conveyor that carries a printed wiring board and moves it horizontally, and sprays a chemical treatment liquid onto both sides of the conveyor. This invention relates to a horizontal conveyor that has been improved to enable uniform spraying of processing liquid onto both sides of printed boards.
近年、プリント板は多層化と高密度化が図られ
ており、精度の良い多層基板を得るため、多層基
板を形成する薄板プリント板を確実に搬送すると
ともに、精度よく製作する必要がある。 In recent years, printed boards have become more multilayered and denser, and in order to obtain multilayer boards with high precision, it is necessary to reliably transport the thin printed boards that form the multilayer board and to manufacture them with high precision.
かかるゆえに、薄板プリント板の確実な搬送
と、各薄板プリント板の両面を精度良く化学処理
することができる水平搬送型コンベヤの出現が要
望されていた。 Therefore, there has been a demand for a horizontal conveyor that can reliably transport thin printed boards and chemically treat both sides of each thin printed board with high accuracy.

た問題がある。
When a thin printed board (0.3 mm) is placed on the rollers and transported using the open layout conveyor described above, when the thin printed board crosses between the pieces, its tip gets stuck between the pieces and falls. In particular, due to the injection pressure of the processing liquid from above, there are many cases in which the leading end of the processing liquid gets stuck between the pieces and falls off, making the transportation unreliable.

る。 On the other hand, in overlapping playout roller conveyance, the frame intervals overlap, so
Although the thin printed board does not fall as described above, the top blocks the spraying of the processing liquid from below, resulting in variations in the coating thickness on the bottom surface.
There is a problem that etching accuracy cannot be obtained.
また、コンベヤの断面が水平であると、上方よ

溜つて上面の塗布厚が不均一となり、エツチング
精度等が得られないといつた問題も発生する。 Furthermore, if the conveyor has a horizontal cross section, the processing liquid sprayed from above will accumulate on the top surface of the printed board 4, resulting in uneven coating thickness on the top surface, causing problems such as poor etching accuracy. .

る。 As shown in Figure 1 a and b, frames 1-1 to 1-
The conveyor belts are arranged so as to overlap each other in a stepwise manner with a constant period, and the longitudinal section of the conveyor is curved so as to have a middle height as shown in FIG.

By arranging the frames 1-1 to 1-n so as to overlap each other at a certain period, the area covered by the frames on the bottom surface of the printed board 4 is reduced, and the etching solution is sprayed uniformly from below. This improves the etching accuracy of the lower surface, and prevents the thin printed board from falling between the frames.

せた構成としている。 As shown in FIG. 1a, the conveyor of the present invention comprises:
The pieces 1-1 to 1-n are arranged in a stepwise manner so as to overlap each other at a constant period, and the cross section of the conveyor is curved to have a middle height as shown in FIG.

チング液等の化学処理液５が吹きかけられる。 As shown in FIG. 2, the operation is such that the thin printed board 4 is placed on the frames 1-1 to 1-1-
A chemical processing solution such as an etching solution is sprayed onto both sides of the plate by sprayers 3-1 and 3-2 installed above the printed board and below the frame. 5 is sprayed.

なる。 Furthermore, since the thin printed board moves sequentially between the pieces arranged in a stepwise manner, its tip does not fit between the pieces, and the falling of the printed board 4, which was a problem with conventional open layout conveyors, is eliminated.
第３図に示す一実施例のコンベヤは、コマを連
結する軸をフレキシブル継手６−１〜６−ｎと

ツチング精度等の化学処理が向上する。 As a result, the printed board 4 is bonded to the top surface and curved due to the spray pressure of the processing liquid from above, and the upper surface becomes medium-height, so that the etching liquid 5 on the upper surface smoothly drips, and the processing liquid is distributed uniformly. Chemical processing such as etching accuracy on the top surface is improved.
