Equipment
is the working means that are divided in universal equipment or
equipment dependent on the components to be processed
The equipment is manipulated by a
manual operator or automated equipment and controlled with automated
systems through various manipulation
systems, such as systems of supports
for components, robots, systems of
linear axes, sorting installations, storage systems, »Pick & Place« units and
automated conveyer bands.
The manual devices are necessary
for the production of prototypes
for the production of first samples
as auxiliary means for starting the
preproduction of a product
for the lot production of variants
of types with small lots and
for making products in a very
small number.

Our basic competences in the field of devices include the
production of the following
The equipment can be integrated
as tools or supports for components
in a manual operation post, a semiautomated or completely automated
installation.
The equipment characteristic is that
it is used or can be replaced as a
complete module.

Automatic machines with rotary transfer
Compact and advantageous solutions for the automation of processes
The automatic machines with rotary
transfer and manual equipping and
controlled by an operator are used
at the production of lots with small
quantities.
These increase the automation degree
and thus costs per piece for the produced unit are reduced. The automatic
machines with rotary transfer have the
advantage of being built in a compact
way, they require a reduced necessary space and also have very reduced
switching-over cycles. By comparison,
the costs of investment in equipping
the machines are also reduced.
The automatic machines with rotary
transfer with semi-automation – we
are also talking about hybrid assemblage – are used by an operator who
manually introduces the components
to be assembled, namely the components to be verified. After introduction,
a sensor determines if the component
is correctly placed and the rotary disk
will guide after a station, after the
safety door was manually closed.
Instead of a safety door, a light curtain
can also be used, which will guide the
rotary disk further, immediately after
the operator leaves the area monitored by the light curtain.
The automatic machines with rotary
transfer can be completely automated
by manipulating the location, for
example by a robot.
At the illustrated automatic
machines with rotary transfer,
the component to be processed,
respectively the sample, are
manually placed in the support
for components on the rotary
disk. In a second station will
be carried out for example the
assemblage process. In a third
station takes place the testing
process and in a fourth station
will be marked the component
to be processed and/or it will
be automatically placed on a
taking-over band.

Transfer systems for supports of components
High power, smart and flexible systems for different requests.
The transfer systems for supports of
components are distinguished by a
larger flexibility. This means that the
processes from the assemblage and
verification line can be removed,
namely completed. Moreover, the
assemblage and verification processes
of great variety can be also carried out
with the transfer systems. It is possible
a combination of manual and fully
automated stations inside the production line.
1
The selection of the support for
­components allows higher sizes.
The particular conditions have an
important role in installation design.
The complex assemblage sequences
require a larger flexibility when
­selecting systems and structuring
design.

The transfer ­systems
for supports of
­components are
distinguished by the
following installation

Round construction
U-shaped construction
The automation of ­verifications
The samples delivered on pallets
or on supports for components
will be taken over from the conveyer band in the verification station by a portal robot. There, the
components will be connected,
tested and the measurement of
the introduction/extraction force
and rotation moments will be
carried out.

Lifting assemblage for lines
The conductor pads for exhaustors will be placed manually on
the supports for components and
then they will pass through a
heating station, plasma cleaning
station, assemblage station for
arm lifters with automated label
supply, as well as a Pick&Place
unit with grabber for needles and
a final pressing unit.

The assemblage of the
­operation field for the door
The operation fields for the door
will be assembled in different
variants, in manual and automated stations, namely cleaned,
tested, screwed up and marked.
3
Module assemblage
At this assemblage system for
supports of components, the
individual components will be
placed and assembled manually
in the fastening places on the
support for components. In different stations, the components
will be tested and adjusted. In
the last stations takes place the
thermal welding of the entire
subassembly.

Manual manipulation systems
For the complete automation of processes
»Catch things, from the place
they can be picked up«
Epiktet (50–138 A.D.)
The manipulation technique is the
material means or devices which
transport the material flow from one
post to another.
In the automation technique, robots
are used for completely ­automating
the assemblage and/or testing process. For this are used loading and
unloading stores in order to maintain
the buffer of components.
Portal axis robot
In the right part of the image
you can see two portals with 3D
arm with 5 axes each.
X-Y-Z axis will be completed by
a rotation axis to which is
connected another linear axis.
Portal

3D arm portal
with 4 axes:
Within this completely automated
assemblage process, the injector is
assembled in the nozzle casing, by
means of two sorting containers and
a storage bin of components, as well
as a 2D line portal with pneumatic
grabber.
3D space portal
with 3 axes:
In the figure below it is illustrated
a 2D line portal with double,
pneumatic grabber.
The robot with articulated arm exists, for
example as robot with 5 and 6 axes with 5,
namely 6 rotation axes.
In the left part of the image you can see a
WIG welding automatic machine using a
robot of 6 axes.

Test stands
Installations for the verification of products or other components
The life duration ...
The test stands are important means
for assuring the quality, for reducing
at minimum the losses of products.
The life duration of products can be
presented tipically in a diagram, the
so-called »duck curve«, as failure rate,
depending on the life duration (see
the chart).
determines the period in which a
technical product can be used without
replacing the central components or a
complete failure. In order to ensure the
quality, it is important to test the mechanical and electrical characteristics
of the new products even from the time
of their development. For this purpose,
test stands are used for determining
the life duration. For this, the samples
are mechanically fixed in supports and
Examples
1 Test stand for electric tools
2 Test stand for switches of electric tools
3 Test stand for safety switches
4 Test stand for safety switches for hinges

exposed to a permanent alternating
request (for example rotation moment
and/or traction force – compression
force).
This happens uninterruptedly, usually
for a period of up to three months.
Within this period, the parameters to be
measured will ve recorded (for example
moment of rotation, force, speed, track,
current, temperature).
Incircuit Tests ...
End of Line Tests (EOLT) ...
are testing procedures by which the
(electronic) pretested product is subject
to an intermediary verification before
continuing the production, namely
assemblage. By intermediary verifications, the products that are not good
are evacuated before reaching the
final process (final assemblage or final
production). The intermediary verifications will be carried out for example at
conductor plates and even at modulary
equipped conductor plates. The adhesion problems, errors at components,
including couplings, are tested.
are testing procedures in production
by which the 100% functioning of
newly produced products is verified at
the end of the production process.
Also, these serve for ensuring the
quality, their name coming from the
fact that most automated test stands
are directly at the end of assemblage
and production lines, from spatial
point of view.

Automation for permanent tests
in the temperature panel
Stress-Screening
Stress-Screenings are the tests concerning the life duration, in which the ageing of products is strongly accelerated
by using quick and extreme modifications of the temperature (Temperatures
of –70°C up to +250°C). Hot stamps,
rooms for high temperatures and temperature testing cabinets are used for
this purpose. It can be verified either
in constant temperature conditions
or in conditions of temperature that
modifies in time. Through this testing
procedure, the development time of a
product until it will be ready for the lot
production is reduced, along with the
simultaneous reduction of costs.

Electrotechnique and software
The brain and neurological centre of the machine
A part of the automation technique
includes the project and orders. Here
are included the hardware design,
the construction of the control panel,
the installation cabling, the software
­creation and activation of the automation process. Depending on the input
sizes (for example the position of a
button or a sensor) the output sizes
will be modified by using an actor
(for example valves or engines).
The construction of distribution
installations
Electric constructions with
electric scheme
Software
The control panels are created at
random sizes, from the individual
component to the lot production.
This usual construction software allows a
documentation which can be used without
problems at the extensions of machines
and/or modifications of machines and can
be adapted – of course complying with the
current norms for electric safety.
The software of the machines is created on
Hard- and Soft PLCs, as well as on PCs.
For this, we use orders from Siemens (S7)
and Beckoff.
The PC-based software is created with
LabVIEW from National Instruments and
Microsoft Visual Studio.

will be programmed with programming languages such as LabVIEW or C-Sharp.
These can have extensive additional functions, such as complex visualizations,
protocols and statistics (see also the paragraph Measuring technique).
Complex automatic machines with a variety of functioning sequences for which
are not used additional functions, such as the above-mentioned visualizations,
protocols and creation of statistics, controlled by PLC.
The complex automatic machines for which are used the above-mentioned additional functions receive besides PLC an IPC subordinated order.
The simple automatic machines for which are used additional functions receive only
an IPC order.
The quality of the component to be processed is evaluated with an automated optical inspection. By using an image processing
system – executed with camera, lens and
illumination under a darkening hood – different parameters are evaluated, such as light
brightness, contrast and colour and a limit
value is defined for the good/bad evaluation. The existence and correct positioning of
defective components can be detected, being
determined including the cracks from components. Also, it is possible to recognize the
writing and symbols, as well as to determine
the lengths and width.
The hardware for the
measuring technique
is usually integrated
in a separate control
panel for the control
technique.
