Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention [Field of Industrial Application] The present invention relates to a rack device that can automatically mount and store printed circuit boards.

[Conventional technology]

Electroplating/electroless plating process for printed circuit boards,
Regarding the racks (contact jigs) used in the process of electrodeposition of photosensitive electrodeposited resist onto printed circuit boards, conventionally there are racks (contact jigs) as shown in FIGS. 6, 7, and 8, for example.

The rack shown in Figure 6 is currently used for boat fishing.
A hanging plate piece Oi is provided facing the parallel side rod hanging from the power feeding horizontal rod (cathode rod), and the side rod (A) and the hanging plate piece ath
The printed circuit board αb is inserted and held between the two. The rack shown in Fig. 7 can be automatically installed by a robot, and the hanging plate pieces A6 are provided oppositely on the side bars (4).
The upper and lower ends or both ends of the printed circuit board αb are sandwiched between the upper and lower ends of the printed circuit board αb.

In the rack shown in Fig. 8, a thin hanging piece O6 is inserted into the side rod, and the hanging piece O6 is inserted into the small hole formed in the α center of the printed circuit board so as to be hooked. It is something.

[Problem to be solved by the invention]

Among the above-mentioned conventional printed circuit board racks, those shown in FIGS. 6 and 7 can be used to insert the printed circuit board Qll due to the adhesion of plating to the hanging plate piece a6 or deformation of the hanging plate piece αi during use. It becomes difficult to pinch. In addition, the printed circuit board αb may become loose due to weakened springiness, and even when automatically mounted by a robot, it is necessary to adjust the retaining plate O6 by hand from time to time. Furthermore, in the case of the one shown in FIG. 8, plating adheres to the α crest of the thin latching piece, making it difficult to insert it into the center of the small hole α of the printed circuit board αb, or conversely, making it difficult to remove it from the surface of the small hole. Moreover, all of the above-mentioned racks cannot accommodate different widths of the printed circuit board surfaces, and have the problem of having to be replaced with another rack.

The present invention aims to solve the problems of the conventional printed circuit board racks described above. That is, an object of the present invention is to provide an automatic printed circuit board mounting rack device that can automatically firmly hold and release printed circuit boards, and can also readily accommodate printed circuit boards of different widths.

Structure of the Invention [Means for Solving the Problems] The printed circuit board automatic attachment/detachment type rack device of the present invention is composed of a rack body (1) and an opening/closing operation means (2) +2), and the rack body (1) has the following features: , the power feed horizontal rod (3) and the pair of side rods (4) (4) vertically installed from the power feed horizontal rod (3).

7) (7) and each side rod (4) (4)
A concavo-convex portion (8) (8) that can engage with the concave-convex portion (7) (7) of the power feeding horizontal rod (3) is formed on the side of the power feeding horizontal rod (3), and a double concave-convex portion (7) is formed.
(8) (7) Engage (8) at any position, and
6) Tighten and fix the bolts (9) (91) through (6), and place the rods (4) on both sides at opposite positions of (4).
A clip-type latching portion QI Ql is provided, which is normally closed by a spring force and can be opened when pressed, and the opening/closing operation means (2) is provided.
) (2) is the hanging part 01α10 of the rack body +1)
) (10) is provided with pressing means capable of opening the printed circuit board θυ against the spring force at the position where the printed circuit board θυ is attached to the rack body (1) and at the position where it is removed.

In the above configuration, the power supply horizontal rod (3) and each side rod (4) (
4) Fixed part (5) (5) uneven part (7) (7)
The uneven portions (8) (8) may have, for example, a serrated cross section as shown in the figure, but are not limited to this, and may include a large number of uneven portions (7) (7) equally spaced in the longitudinal direction of the power feeding horizontal rod (3). are lined up,
An uneven part (8) that can be engaged with the uneven part (7) (7)
(8) should just be formed on the side rod (4) (4).

These uneven portions (7) +7) and uneven portions (8) (8) may be provided on a vertical surface when the side beams (4) (4) are vertical as shown in the example shown, but they are not limited to this. For example, the power supply horizontal rod (3) is provided on the upper surface, and the side rod (4) (4) is provided with a horizontal portion on the upper surface and formed on the lower surface, and an uneven portion (
7) (7) - Concave and convex portions (8) (8) may be engaged.

The latching portion 0101 is of a clip type that is normally closed as described above, and is provided at a position opposite to the rods (4) on both sides so that it can be opened in the opposing manner. (2) +2), so it suffices to use something with a strong clamping force.

The opening/closing operation means (2) (2) is, for example, an air cylinder as shown in the figure, and its loft presses the above-mentioned latching portion Ql 01 against a spring force so that it can be opened.

The opening/closing operation means (2) (2) is provided at the mounting position of the printed circuit board on the rack body (1) and at the detachment position, for example, in an electroplating/electroless plating treatment tank, or in a photosensitive electrodeposited resist. These are the front and rear positions of the electrodeposition treatment tank, etc.

Please note that loading the printed circuit board αυ into the rack body (1)
The state at the time of carrying out is preferably such that it is on the same plane as the side rod (4) (4), in other words, it approaches from the side of the hooking part αIQI. Therefore, for example, a rack body rotating means (not shown) for horizontally rotating the rack body (1) at that position and a printed circuit board αυ in the same position as the rack body (1) are provided at the printed circuit board mounting position and the detachment position. It is sufficient to provide a substrate carrying-in means (2) and a substrate carrying-out means (2) which can be transferred in a planar manner.

(Function) Next, the state of use of the automatically removable printed circuit board rack apparatus of the present invention will be explained.

Attach the printed circuit board Ql) to both side rods (4) of the rack body (1).
(4) Before clamping with the hanging portion QI Ql, the interval between the side rods (4) (4) is first adjusted according to the width of the printed circuit board αD.

To do this, loosen the bolts (9) (9) at the fixed part (5) between the power supply horizontal bar (3) and the side bar (4) (4) and the upper part (5), and then remove the uneven part (7) (7).・Remove the engagement between the concave and convex portions (8) (8), and attach the latching portion QI of each side rod (4) (4).
Ql slides the printed circuit board (11) to a width that allows it to be held (see arrows a-b in Figures 2 and 3), and uses that width to form uneven portions (7) (7) and uneven portions (8) (8). ) and then tighten and fix the bolts (9) again.

Then, rotate the rack body (1) horizontally at the position where the printed circuit board 0υ is attached to the rack body (1),
As shown in FIG. 1, it is placed on the same horizontal plane as the substrate carrying means. In this case, the lower end of the side rod (4) (4) of the rack body (1) faces toward the base @carrying means (2), in other words, toward the rear.

An opening/closing operating means (2) is provided at this position, and after the opening/closing operating means (2) approaches the latching portion (II 01) from both sides as shown by arrow C in Figs. 1 and 5. , by pressing the latching part QI Ql as shown by the arrow d in both figures, the latching part α [α] is opened. It is fed horizontally from the rear side and enters between the portions Q101.Then, when the opening/closing actuating means (2) stops pressing, the opening of the latching portion α and αΦ is closed. As shown in the figure,
Each of the latching parts Ql (11) firmly clamps the edge of the printed circuit board. This means that the printed circuit board αυ is automatically and firmly attached to the rack body (1).

Subsequently, the rack body (1) is vertically rotated as shown in FIG. 2, immersed in the processing tank and subjected to processing, and then moved to the position from which the printed circuit board OD is removed.

At the board removal position, the rack body (1) becomes horizontal again, similar to the board mounting position shown in FIG. Then face forward. In this state, the opening/closing actuating means (2) approaches the latching portion αIQI of the rack body (1) from both sides,
By pressing the latching portion αIQ10) (10), the latching portion QI Ql opens. Therefore, the board carrying out means 0 holds the front end of the printed circuit board αυ and the hanging part Q
Just pull it out from I Ql.

The printed circuit board αυ has now been automatically removed from the rack body (1), and after that the printed circuit board QO is
What is necessary is to transport it to the next processing step, for example, exposure fi (not shown). Further, the empty rack body (1) is returned to the initial printed circuit board mounting position again by another transport means (not shown).

In addition, when transporting printed circuit boards αυ with different widths, loosen the bolts (9) (9) in the same way as above to tighten the connection between the uneven parts (7) (7) and the uneven parts (8) (8).・Remove the mating condition and remove the latching part αI (1) of each side rod (4) (4).
Adjust the width so that 1 can hold the printed circuit board αυ, and use that width to form the uneven part (7) (7) and the uneven part (8)
(8) and then tighten and fix the bolts (9) (9) again. This allows immediate adaptation to printed circuit boards Ql) with different widths.

Effects of the Invention As is clear from the foregoing, the printed circuit board automatic attachment/detachment type rack apparatus of the present invention has the following effects.

i) In the present invention, the printed circuit board is automatically and firmly mounted.
Can be released and transported.

In other words, with conventional racks of this kind, for example, plating may adhere to the board hanging plates or the hanging plates may become deformed, making it difficult to insert and hold the printed circuit board, or the springiness may weaken and the printed circuit board may become stuck. Sometimes it got thinner. There is also a thin hanging piece,
The small piece that hooks into the small hole of the printed circuit board has plating attached to it, making it difficult to insert it into the hole (or conversely, it becomes difficult to remove it from the small hole. There were problems such as the need to adjust the stop plate piece by hand from time to time.

However, in the present invention, since the latching portion of the rack body is opened and closed at a predetermined position by the opening/closing operation means, a strong clip-type latching portion can be used. Further, the present invention is configured such that the printed circuit board is entered from the side of the open hooking portion and closed and clamped, or the printed circuit board is opened and the printed circuit board is pulled out and conveyed to the next process. Therefore, unlike conventional rack devices, the rack device of the present invention is capable of automatically and firmly mounting printed circuit boards, removing them, and transporting them.

ii) The rack device of the present invention can readily handle the transportation of printed circuit boards of different widths.

That is, in conventional racks, the power feed horizontal bars and side bars are not removable, and therefore only printed circuit boards of a certain size can be mounted and transported.

On the other hand, in the present invention, the fixed part between the power feeding side rod and the side rod is removed by loosening the bolt and disengaging the engaged state between the uneven parts and the uneven parts.
The structure is such that the width can be adjusted to allow the printed circuit board to be held by the hooking portions of each side lever, the uneven portions and the uneven portions can be engaged at that width, and the bolts can be tightened and fixed again. Therefore, the present invention differs from the conventional ones in that it can be mounted and transported in response to printed circuit boards of different widths.
