[0001] The present invention is directed to a holding tool for fixing an electronic component
during a manufacturing process, said electronic component, comprising a winding assembly
and an electronic circuit, the holding tool comprising a holding tool body; first
and second jaws disposed at the holding tool body relatively movable to each other
in a first direction; and first and second wire guide means. The invention is further
directed to a circular table manufacturing unit comprising a circular table to which
at least one holding tool is mounted.
[0002] Such a holding tool is known from
EP 0 573 469 B1. In this known holding tool each jaw is provided with a wire guide pin about which
a wire wound around a core of the winding assembly is guided in order to position
a respective wire portion between the winding assembly and the respective wire guide
pin over an associated contact portion of the electronic component so that the wire
can be bonded or soldered to the contact portion.
[0003] It is very difficult with this known holding tool to place each wire exactly over
the respective contact portion because the cores of different winding assemblies do
not have exactly the same diameter. As the core is clamped in between both jaws the
lateral distance between the jaws, in the closed position of the holding tool, depends
on the diameter of the core. Thus, also the lateral distance between both wire guide
pins is also depending on the diameter of the core of the actually manufactured winding
assembly.
[0004] Furthermore, if the wire wound on the core is not exactly guided during the manufacturing
process of the winding assembly, the outer diameter of a fabricated winding assembly
may slightly differ from one winding assembly to another one.
[0005] As a consequence, the inclination angle of the respective wire with respect to a
plane of symmetry of the jaws between the winding assembly and the associated guide
pin differs from winding assembly to winding assembly so that the position of the
wire over the contact portion of the electronic circuit is not always the same for
each electronic component. Thus, misalignment of the wires may occur so that waste
products are produced.
[0006] The known prior art embodiment is usually used together with a circular table manufacturing
unit to which the known holding tool is mounted. During the manufacturing process
of an electronic component with such a circular table manufacturing unit the wire
guide pins mounted to the jaws according to the prior art cannot be adjusted at a
position of the circular table manufacturing unit in which the precision of the position
of the wires over the contact portions of the electronic circuit can be evaluated
because at said position there is not enough space above the holding tool that could
provide access to the guide pins. Thus, an adjustment of the wire guide pins can only
be carried out in a subsequent position. In this subsequent position, however, the
wires are already bonded or soldered to the respective contact portions and the wires
are not longer guided around the wire guide pins. Therefore, it is difficult to adjust
the wire guide pins and the result of such an adjustment can be evaluated only after
a further sequence of manufacturing steps is carried out. Thus, the adjustment of
the wire guide pins of a known holding tool mounted to a circular table manufacturing
unit is an iterative process which will lead to several waste products.
[0007] It is thus an object of the present application to define a holding tool according
to the preamble of claim 1 which overcomes this disadvantage of the prior art and
which allows to reduce the production of defective work during the manufacturing of
electronic components comprising a winding assembly and an electronic circuit.
[0008] It is another object of the present application to define a circular table manufacturing
unit comprising such a holding tool.
[0009] The first object is achieved by the holding tool as defined in claim 1.
[0010] The provision of the first and second wire guide means at the holding tool body remote
from the jaws allows the positioning of the wire portions between the core of the
winding assembly and the respective wire guide means in a reliable and reproductable
manner exactly over the associated contact portion of the electronic circuit.
[0011] In a preferred embodiment at least one of said first and second wire guide means
is movably disposed at the holding tool body wherein at least the one of the first
and second wire guide means can be moved in a plane parallel to the first direction.
This movability allows it to easily adapt the position of the associated wire portion
dependent on a change in diameter of the core of the winding assembly.
[0012] Preferably said first and second wire guide means each comprise a wire guide pin
mounted to a crank provided on a shaft rotatable about an axis which is remote from
the axis of the wire guide pin. This preferred embodiment provides a wire guide means
with which the position of the respective wire portion can be easily adjusted.
[0013] Preferably each crank of this holding tool is provided at an upper end of the respective
shaft and positioned above an associated one of the jaws.
[0014] In case that each shaft of such a holding tool extends below a lower surface of the
holding tool body an adjustment of the respective wire guide means and thus of the
associated wire portion can be easily carried out from below the holding tool body.
For easily actuating the respective positioning mechanism for each wire guide means
each shaft is preferably provided with an actuator arm.
[0015] It is further preferred that said first and second movable wire guide means are provided
with coupling means that can be coupled each to a drive means. This feature allows
it that the wire guide means are coupled to an external drive mechanism so that no
manual action for aligning the respective wire portion will be necessary.
[0016] In such an embodiment it is preferred that a coupling means is provided at each one
of the shafts.
[0017] The second object of the present invention is achieved by a circular table manufacturing
unit comprising a circular table to which at least one holding tool according to the
present invention is mounted.
[0018] Preferably such a circular table is a multi-position circular table in which separate
manufacturing steps are carried out at different positions. In this preferred embodiment
the drive means are provided at the circular table manufacturing unit on at least
one position of the circular table wherein the drive means is adapted to be coupled
to the coupling means of said first and second wire guide means. Preferably the drive
means is placed below the circular table and thus below the lower surface of the holding
tool so that the space above the holding tool is not affected by the drive means for
the first and second movable wire guide means.
[0019] It is also an object of the present invention to provide a method of manufacturing
an electronic component comprising a winding assembly and an electronic circuit which
reduces the number of wrongly manufactured waste products.
[0020] This object is achieved by a method of manufacturing an electronic component comprising
a winding assembly and an electronic circuit, the method comprising the steps of:
providing the electronic circuit on a holding tool; feeding a core for the winding
assembly to the holding tool and fixing the core in the holding tool; applying a wire
on the core in order to produce the winding assembly; bonding the wire to contact
portions on the electronic circuit; fixing the wire on the winding assembly and removing
the electronic component from the holding tool; wherein the position of the wire over
the contact portions of the electronic circuit is checked and, if necessary, adjusted
so that the respective wire portion is exactly positioned over an associated contact
portion before the wire is bonded to the contact portions.
[0021] The step of checking and, if necessary adjusting the wire portions before the wire
is bonded to the contact portions ensures that the respective wire portion is exactly
bonded to the associated contact portion.
[0022] It is preferred that the adjustment of the wire is carried out by displacing guide
means provided on the holding tool for guiding the respective wire portion extending
away from the winding assembly.
[0023] A best mode of carrying out the invention is now described with reference to the
drawings in which
Fig. 1 is a perspective view of a holding tool according to the invention;
Fig. 2 is a top view of the holding tool;
Fig. 3 is a front view of the holding tool as seen in the direction of arrow III in
Fig. 2; and
Fig. 4 an enlarged partial top view of the holding tool as shown in Fig. 2.
[0024] Certain terminology is used in the following description for convenience only and
is not intended to be limiting. For example, words such as "upper" designate directions
in the drawings to which reference is being made. Also in the drawings, where similar
reference characters designate like parts throughout the several views, illustrated
is a preferred embodiment of the present invention. It will be appreciated by those
skilled in the art that the particular embodiment shown throughout the drawings is
offered as an example which incorporates the teachings of the present invention and
is merely exemplary.
[0025] The holding tool 1 shown in the drawings comprises a holding tool body 10, a first
jaw 12 and a second jaw 14 disposed at the holding tool body 10 relatively movable
to each other in a first direction A perpendicular to a plane of symmetry Z of the
jaws 12, 14. The first and second jaws 12, 14 each are provided with a gripping portion
11, 13 at a tip end of each jaw 12, 14.
[0026] The gripping portions 11, 13 are adapted to clamp a core 22 of a winding assembly
20 of an electronic component 2 to be manufactured in the holding tool 1.
[0027] The gripping portion 11, 13 is also adapted to accommodate an electronic circuit
24 of the electronic component 2 in a recess 15 of the second jaw 14 as can be seen
in Fig. 4. A spring 17 provided at the first jaw 12 holds the electronic circuit 24
in the recess 15.
[0028] The holding tool 1 further comprises a first wire guide means 3 and a second wire
guide means 4 which are disposed at the holding tool body 10 remote from the jaws
12, 14. Each wire guide means 3, 4 comprises a shaft 30, 40 each rotatable about an
axis X, X' wherein the axes X, X' are parallel to each other and perpendicular to
the first direction A. In the example shown in the drawings the axes X, X' are vertically
aligned and the shafts 30, 40 are positioned adjacent to the respective gripping portion
11, 13 of the jaws 12, 14 on the left side and on the right side of the jaws 12, 14,
respectively, as can be seen in Fig. 2.
[0029] Each shaft 30, 40 is provided at the upper end thereof with a crank 32, 42 extending
in a plane perpendicular to the respective axis X, X' above an associated one of the
jaws 12, 14 as can be seen in Fig. 3.
[0030] Each crank 32, 42 carries a wire guide pin 34, 44 wherein each wire guide pin 34,
44 has an axis parallel to and spaced apart from the respective axis X, X' of the
associated shaft 30, 40. In a normal position the wire guide pins 34, 44 are positioned
above an adjacent one of the jaws 12, 14.
[0031] As each crank 32, 42 is rotatably fixed to the associate shaft 30, 40 a rotating
movement of a shaft 30, 40 will also rotate the crank 32, 42 resulting in a movement
of the associated wire guide pin 34, 44 on a circular path around the axis X, X' of
the respective shaft 30, 40. This rotational movement of the shafts 30, 40 can thus
be used to adjust the position of the associated wire guide pin 34, 44.
[0032] Each shaft 30, 40 is rotatably journalled in a mounting structure 16, 18 mounted
to the holding tool body 10.
[0033] A wire 5 is wound around the core 22 of the winding assembly 20 and end portions
50, 52 of the wire extend between the winding assembly 20 and the first and second
guide pin 34, 44, respectively, as can be seen in detail in Fig. 4.
[0034] The front view of Fig. 3 shows how the holding tool 1 is mounted to a circular table
60 of a circular table manufacturing unit 6. The circular table 60 as well as the
circular table manufacturing unit 6 are only schematically shown in the drawings.
[0035] Whereas, the holding tool body 10 of the holding tool 1 is mounted on the upper surface
61 of the circular table 60, the shafts 30, 40 are positioned radially outward of
the circular table 60 and extend below the lower surface 62 of the circular table
60.
[0036] A schematically shown drive means 64 which also belongs to the circular table manufacturing
unit 6 is disposed below the circular table 60. Coupling means 36, 46 are provided
at the lower end of each shaft 30, 40 as can be seen in Fig. 3. In the example of
the description each coupling means 36, 46 is a gear wheel meshing with an associated
driven pinion gear 65, 66 of drive means 64. Each one of the driven pinion gears 65,
66 can be independently driven by the drive means 64 in order to independently adjust
each wire guide pin 34, 44.
[0037] Instead of or in addition to the previously described electric drive means 64 each
shaft 30, 40 can alternatively also be provided with an actuator arm (not shown) so
that an adjustment of the wire guide pins 34, 44 can be manually carried out by manually
moving the actuator arms.
[0038] The drive means 64 may be provided only at one station of the multi-station circular
table wherein different manufacturing steps are carried out in each station. The shaft
30, 40 of the holding tool 1 may be fixed by blocking means (not shown) in order to
avoid that the shafts are rotated and thus the wire guide pins 34, 44 are displaced
when the holding tool 1 is not in the position where the drive means 64 is provided.
[0039] The process of adjusting the position of the wire portion between the winding assembly
20 and the associated wire guide pin 34, 44 will be described hereinafter with respect
to Fig. 4.
[0040] A first portion 50 of the wire 5 is positioned exactly above a first contact portion
25 of the electronic circuit 24. A second wire portion 52, however, is misaligned
with respect to a second contact portion 26 of the electronic circuit 24.
[0041] A rotation of the second shaft 40 in a clockwise direction (as seen from above) will
rotate the second crank 42 into the position shown in Fig. 4 in phantom lines and
will thus move the second wire guide pin 44 from its first position in the clockwise
direction to the second position 44'. As the new position 44' of the wire guide pin
44 is laterally more spaced apart from the plane of symmetry Z of the jaws 12, 14
the wire portion 52 between the winding assembly 20 and the second wire guide pin
will move to the right, shown as the dashed line 52' in Fig. 4, and will thus be positioned
exactly over the second contact portion 26 of the electronic circuit 24.
[0042] This adjusting process is part of a method of manufacturing an electronic component
which is usually carried out on a multi-station circular table 6 wherein the circular
table is provided with six stations. In the first station the electronic circuit 24
is provided on the holding tool 1 and placed in the recess 15. In the second station
the core 22 is fed to the holding tool 1 and fixed between the gripping portions 11,
13. In the third station the wire 5 is wound on the core 22 in order to produce the
winding assembly 20. In the fourth station the position of the respective wire portion
50, 52 over the associated contact portion 25, 26 of the electronic circuit 24 is
checked and if the wire portion is misaligned the above described adjusting step is
carried out. Then, the wire portions 50, 52 are each bonded to their associated contact
portion 25, 26. In the fifth step the wire 5 is fixed on the winding assembly 20,
e.g. by blowing heated air on the winding assembly whereupon the outer insulation
of adjacent windings of the wire adheres together. In a sixth step the electronic
component 2 is removed from the holding tool 1.
[0043] The invention is not restricted to the above-described exemplary embodiment, which
only serves for a general explanation of the core concept of the invention. Rather
more, it is within the scope of protection that the holding tool and the circular
table manufacturing unit in accordance with the invention could also adopt different
forms than those of the embodiments described above. In particular thereby, the holding
tool and the circular table manufacturing unit may comprise features which represent
a combination of the respective individual features of the claims.
[0044] The reference symbols in the claims, the description and the drawings serve only
to provide a better understanding of the invention and are not intended to limit the
scope of protection.
