Description
13~9~3 The invention relates to a clamp holder for clamping boards or board-shaped components to them to be suspended in or removed from electroplating baths.
A holding clamp of the prior art which was marketed by the applicant provides for two clamping projections on one of the clamp halves and one clamping projection on the other clamp half, this latter clamping projection being located in the centre between the two clamping pro~ections of the first-mentioned clamp half, viewed in the Iongitudinal direction of the clamp halves. ~hi~ has several disadvantages. Such clamps should hold boards at their edges in such a way that pendulum movement about this point of holding is avoided or at least kept at a minimum. If the distance between the two clamping projections of the one half of the clamp is termed L, the effective lever is only L/2 because of the central arrangement o~ the clamping projection of the other clamp half. If this disadvantage is to be compensated for, the ~orce of the spring system must be increased. This, however, has it~ limits, and it must also be borne in mind that if the ~orce o~ the ~pring is too great there is a risk of the edges o~ the boards held by the clamp being squeezed by the central clamping pro~ection since these boards are frequently very thin. If on the other hand, the distance L between the two clamping pro~ections of the one half of the clamp i~
2S increa~ed, the edge of the board required for holding by the clamp must be made correspondingly larger. Since for electroplating purposes the edge area is lost, the area of the board which can actually be electroplated (compared to other boards of the same overall dimensions) is correspondingly reduced. A similar clamping arrangement which,apart from this, is very complicated in its design forms the subject matter of DE GM 8422297.
The invention improves the function of a clamp holder in such a way that the effective lever available for clamping the particular board is doubled without it being necessary to ~3~ ~6~
increase the size of the edge area of the board to be held by the clamp holder.
In one aspect, the invention provides holding tongs for clamping plates or plate-shaped objects to be suspended in and removed from galvanizing baths, comprising two halves having clamping pro;ections and being biased by springs so that due to a spring action the clamping projections of said two halves press against a plate to be clamped, a first one of said halves being subdivided into two movable portions, a second one of said halves being fixed, each of said portions being pivotable relative to said fixed second half under said spring action, each of said movable portions having a clamping projection, said fixed second half having two clamping projections each corresponding to a respective clamping projection of said movable portions and lying opposite thereto in a clamping position; and a pivot axle, ~aid movable portions being pivotable about said pivot axle relative to 6aid fixed half, each of said portions and caid fixed half including a base wall and side walls extending from ~aid base wall at right angle~, each side wall having an opening receivlng said pivot axle, each movable portion and said fixed hal~ including arms laterally extending from said base wall towards said side walls, said arms supporting said clamping projections.
In preferred embodiments of this aspect, the invention provides:
The above holding tongs, wherein said fixed half has a supporting extension, and further including a support of a galvanizing device, said supporting extension being suspended on said support.
~ 3 ~ 3 The above holding tongs, wherein said base walls form bearings for supporting said springs for biasing said halves, said springs being parallel to each other and operating independently from each other for actuating a respective movable portion.
The immediately above holding tongs, wherein one of said movable portions is narrower than the other, said side walls of said movable portions and said fixed half overlapping each other so that the side walls of said narrower portion are positioned between the side walls of said fixed half and said side walls of the wider portion.
The invention will now be described in more detail by way of example only, with reference to the accompanying drawings, in which:
F~g. 1 shows schematically the application of clamp holders in accordance with the invention in an electroplating plant at a scale reduced compared with the further figures.

Fig. 4, 5 ~how a top and side view of the second clamp half, Fig~. 6, 7 show a top and side view of a clamp part of the first clamp half, Figs. 8, 9 8how a top and side view of the other clamp part of the first clamp half.
~3:~96~
Fig. 1 shows an electroplating bath 1 containing several boards (in this case printed circuit boards 2) which are to be electroplated therein and which are held by clamp holders 3 fixed to or hung over what is termed an article transporter 4. With the aid of the article transporter 4 and the holder 3 the circuit boards 2 to be electroplated can be immersed in the bath or removed upwards therefrom on completion of electroplating.
Figs. 2, 2a and 3 show such a clamp holder 3 with the first, movable clamp half 5 divided into two clamp parts 6, 7. The other, second fixed (unmovable) clamp half 8 is connected in a pivotable manner with the two clamp parts 6,7 via axle 9 common to these two clamp parts.
In addition part 8' of clamp half 8 represented in Fig.
3 at the top serves for suspending or fixing the clamp to the article transporter 4.
There are two compression springs 10,11 which are intended for pivoting the movable clamp parts 6,7 in the direction of arrow 12 (Fig. 3) about axle 9. The movable clamp parts 6,7 are provided at the tip with clamping projection~ 13 and 14 which are located at a distance L from each other. On the second fixed clamp half 8, at the same dl~tance L, two clamping projections 15,16 are provided which ln their clamped position ~see in particular Fig. 3) are located opposite to the related clamping projections 13,14 of the clamp part 6,7 and hold the circuit board 2 between them under the pressure of the springs 10,11. Since each movable clamp part 6,7 is associated with its own compression spring 10 and 11, these clamp parts are each pivoted separately and can thus act against the circuit board 2 each by itself with the corresponding clamping force. By means of such clamp holders, circuit boards of various thicknesses can thus be reliably held by the two pairs of clamping projections 14,16 and 13,15 at dlstance L. This would not be possible if the ,.~
~ 3 ~
movable clamp halves were not, as is here the case, split into two separately movable clamp parts. In the latter case a change in the thickness of the board to be held would result in a situation where either the pair of clamping pro;ections 14,16 or the other pair 13,15 would no longer hold the particular board in a firm clamped manner.
Board 2 has a tendency to swing to and fro in the direction of arrow 27. This must be prevented or at least reduced by the force of the springs 10,11 in combination with the clamp holder and the associated lever L. The larger this level L for a non-electroplatable edge width B of board 2 as small as possible, the more efficient the degree of utilisation of the board area. In practice this width B can be kept smaller than 15 mm.
The clamping force exerted by clamping projection pairs 14,16 and 13,15 is uniform.
The clamp half 8 and the clamp parts 6,7 can be stamped out of sheet metal and formed by bending in a simple manner.
Figs. 4,5 show the second clamp half 8 consisting of a base plate 17 with side rims 18 bent at right angles which ea¢h possess a hole 19 to take the axle 9. Futhermore, the side rims 18 and parts 20 of the base plate continue on to form arms which carry the clamping projections 15,16. These clamplng pro~ections, ~ust like the clamping projections 13,14, may consist of separate parts which are fitted replaceably on the arms. The clamping projections are the elements of such a clamp holder which are subject to most strain. When they are worn out, the whole clamp need not be discarded: rather, it can be kept in use by fitting new tips.
The counterbearings for plugging on the compression springs 10,11 are designated 21.
The two movable clamp parts 6,7 are designed in accordance with Figs. 6,7 and 8,9 basically similar to clamp half 8: they have, however, somewhat different dimensions.
The way in which the movable clamp parts 6,7 and the fixed clamp half 8 fit inside each other, in a quasi box-in-box manner, is shown in particular in Figs. 2 and 2a. The base sections of the movable clamp parts are designated in each case with 22, their bent up ~ide rims being designated 23;
here too, holes 24 are provided in the side rims 23 to accommodate the axle.
Figs. 2, 2a show that the narrower clamp part 7 has a cut-out 28 through which the compression spring lo can pass.
By this means the compression spring lo can be supported between the base of clamp part 6 and clamp half 8 while compreasion spring 11 is supported between the base of clamp part 7 and clamp half 8. Pressure applied to the side of clamp part 6 located at the bottom in Fig. 2a first results in compresslon of spring 10 and then, when clamp part 7 is reached, compression of spring 11, as a consequence of which the clamp action ~see Fig. 3) i8 released 80 that board 2 can be removed. A~ ~oon as the pressure at the arrows 29 is relea~ed, the springs 10,11 again press the clamp parts 6,7 with their clamping pro~ections against board 2, i.e. against the clamping pro~ections of clamp half 8.
The arms 25 formed by the base sections 22 and the sides 23 bear the clamping pro~ections 13 and 14 respectively. In this connectlon pro~ectlons 14 are provided on the lnternally located and thus narrower, movable clamp part 7 and clamping pro~ections 13 are provided on the comparatively wider, movable clamp part 6 the sides 23 of which overlap thosé of the clamp half 8 and those of the narrower, movable clamp part 7 (see Fig. 2a). In addition Fig. 2a shows that the distance between the sides 18 of the fixed clamp half 8 is selected in ~uch a way that the sides 18 are located between the sides 23 of clamp parts 6,7.
13~9~
The smooth design of the clamp halves and clamp parts 6,7 and 8 make for easy so-called rinsability. This term is used in electroplating for a design which permits easy and as far as possible complete rinse-off of any bath residues (acid residues). This purpose is also 6erved by the open space between the arms 10 and 25. In addition the parts of the base 6ections 17 and 22 designated 26 and drawn with dot-and-dashed lines can also be cut or stamped out in order to improve the above-mentioned rinsability.
A holding clamp of the prior art which was marketed by the applicant provides for two clamping projections on one of the clamp halves and one clamping projection on the other clamp half, this latter clamping projection being located in the centre between the two clamping pro~ections of the first-mentioned clamp half, viewed in the Iongitudinal direction of the clamp halves. ~hi~ has several disadvantages. Such clamps should hold boards at their edges in such a way that pendulum movement about this point of holding is avoided or at least kept at a minimum. If the distance between the two clamping projections of the one half of the clamp is termed L, the effective lever is only L/2 because of the central arrangement o~ the clamping projection of the other clamp half. If this disadvantage is to be compensated for, the ~orce of the spring system must be increased. This, however, has it~ limits, and it must also be borne in mind that if the ~orce o~ the ~pring is too great there is a risk of the edges o~ the boards held by the clamp being squeezed by the central clamping pro~ection since these boards are frequently very thin. If on the other hand, the distance L between the two clamping pro~ections of the one half of the clamp i~
2S increa~ed, the edge of the board required for holding by the clamp must be made correspondingly larger. Since for electroplating purposes the edge area is lost, the area of the board which can actually be electroplated (compared to other boards of the same overall dimensions) is correspondingly reduced.
