The wire feeding of the future …
In close collaboration with leading vehicle manufacturers, the developers and product managers of ABICOR BINZEL ROBOTIC SYSTEMS have analysed the special requirements for laser soldering and welding applications in vehicle construction in order to create a wire feeder system that is coordinated optimally to the high demands of each production environment. This resulted in the MFS-V3.1 wire feeder system (the further development of the third-generation master feeder system) with completely newly developed drives. With its modern and precisely matched components, the eBOX is exactly equipped for the constantly increasing requirements profile for laser applications, in particular in vehicle manufacturing around the world.
For example, a wide-range input or the multivoltage connection for supply voltage (can be used worldwide) or a modular mainboard, which allows to operate different types of motor, e.g. different sizes and outputs, or even servomotors.
In addition, the AIDA eBOXes (AutomatisierungsInitiative Deutscher Automobilhersteller – Automation initiative of German car manufacturers / ) have safety relays to make it possible to feed wire in for service work after a drop in voltage by actuating the central key switch.
Another advantage of the new development is an even more exact and precise digital wire feeding through a fast 32-bit controller, which minimises inprocess response times. Optimised maintenance and service interfaces (SD card) for user-friendly operations characterise the new overall system MFS-V3.1.
Adaptable and user-friendly operating / service software
Appropriately for the new eBOX, the operating/service software was radically redeveloped and now comprises very extensive process monitoring and many parameters that can be varied in dependence on the application, including simplified visualisation, documentation of the processes and a fault memory with a plain text display.
Two operation modes can now be differentiated for monitoring with control or observation, for example of the actual wire speed and of the motor current: direct operation mode and job operation mode. In the direct operation mode, all parameters are set by the higherlevel controller, and in job operation mode the parameters can simply be set in the operating /service software and stored in the eBOX. In this case, the individual jobs are only selected by the higher-level controller. This saves valuable bus transmission time and increases the cycle frequency of the overall system. In addition, there are numerous additional setting possibilities and options that can be adjusted individually to the application, such as, for example, hot wire function, wire end sensor or wire retraction.
The operator-friendly user interface of the service software can be operated not only through the system PC but also by means of a control panel (MF Control) from ABICOR BINZEL ROBOTIC SYSTEMS. The relevant settings are easy to access and can be controlled intuitively.
After presetting, maintenance intervals are outputted either directly in the operating / service software or per bus message, so that downtimes are avoided and reliable production is guaranteed. A wire buffer function was integrated to make the process even more secure with wire feeding, increase the quality of the laser seams, reduce the acceleration time and prepare the system optimally for the next application. Here, the wire is fed through the rear drive into the MasterLiner after each feed cycle. This can be set to a limited extent and, again, application-specific, in the operating / service software via the intake current of the rear drive. The wire buffer function guarantees that there is always sufficient wire in the MasterLiner and that friction during wire feeding is reduced to a minimum. The system profits here from the independent activation (separate control loops) of the two drives. With medium and short feed distances, the process can be operated with just one drive (front drive). Operators then profit from the cost reductions that result from saving the second drive.

With the MFS-V3.1, ABICOR BINZEL ROBOTIC SYSTEMS has developed a future-oriented wire feeding system for laser applications that can be integrated optimally into the respective application-specific production environment.
Control system eBOX V3 – The nerve centre of the systems
In the third generation of the master feeder system, a comprehensive new development of the eBOX control unit has been used to meet the complex requirements of wire feeding in laser applications. The result is a completely reworked and optimised eBOX with modular and precisely coordinately components. As the nerve centre of the system, it is ideally equipped for the ever-increasing requirement profile in laser applications – particularly in car manufacturing – all over the world.
The eBOX represents the communication interface between the higher-level plant control and the wire drives of the MFS-V3.1. It houses all the electronic control elements and is available as an analogue/digital version and digitally for various fieldbus systems/interfaces.
Fully digital control circuits as well as consistent separation of logic (Multibus I/O board) and drive technology (axis controller) ensure that individual system components are reproducible in the case of servicing and can be replaced without further adaptation. Time-consuming calibration of analogue tachometer systems or other components therefore belong to the past: fully digital control for a futureproof system.
MFS service software – for complete control
The MFS service software – the comprehensive software package for management, diagnostics, operating status display, fault evaluation and quality recording – was used even in MFS-V2. For the third version of the MFS, the tried and tested service software has been completely reworked, improved and extended with many additional functions.
As usual, the software – which is now licence-free as standard – can be used with the existing system PC in conjunction with an eBOX. As an alternative for managing several eBOX devices, the innovative MF-Control operating panel with fine and precise touchscreen is now also available, making the work of the operator much easier.
The simple and intuitive software user interface allows straightforward use of all functions. For safety, users can be given different usage rights. This is done by assigning a user level. Users can identify themselves and log in with a user login and password or alternatively with a key stick.
The option of job programming in offline mode offers a great advantage that operates independently of the robot, which prevents system standstill. This allows management of several eBOX devices at the same time with software and the MF-Control operating panel.
The main features at a glance:
- Setting and editing of up to 64 different jobs
- Comprehensible documentation of the processes
- Fault display in plain text
- Fault log with analysis and troubleshooting
- Creation and management of freely definable maintenance intervals possible
- Diagnostics: clear system status display, which shows directly whether the system is operational or whether there is a fault
- Several eBOX devices can be given station information by assigning the IP address
- Saved station information is shown in the log files
- Multilingual user interface: six different languages can be selected (German, English, French, Italian, Polish and Spanish)
- Setting the wire buffer function
- Three user levels:
• 0 (read authorisation)
• 1 (authorised to load the config. files)
• 2 (administrator rights)
Flex supply – close to the action
The Flex supply provides optimal feeding of the wire into the process and is ultimately the interface between the wire feeding system and the workpiece. It is fixed to the laser optic and thus adjusts exactly to its movements.
Essentially, the Flex supply comprises the quick coupling fitted on the MF3 Laser Drive, and
the feeding body with wire feeding nozzle. The connection between the two products is made by a flexible liner, which can be shortened as required. Depending on the wire diameter and material, there is also a choice of various liners and wire feeding nozzles.
The feeding body is available both for cold and for hot wire applications. The cold wire variant comes optionally with or without gas feed; the hot wire version is available with gas feeding and cooling. Here, the gas and the coolant are fed separately to the feeding body.
The newly developed torch clamps allow precise adjustment of the feeding bodies and also guarantee high reproducibility.
The advantages in brief:
- Can be shortened individually due to the flexible liner between feeding body and quick coupling
- Feeding body for cold & hot wire with or without process gas
- Can be adapted to all standard laser optics
- Quick, safe fitting and changing of the body with a specially adjustable clip system
- Excellent accessibility and optimal seam surfaces due to new design with coaxial gas feed
- With the new design, the gas nozzle is no longer required, which reduces the wear parts
MF3 Laser – the driving force
The newly developed MF3 Laser Drive lifts the master feeder system to a higher level. Having been developed specifically for laser applications, it scores points with its small size, light weight and variety of connection systems. It can be used either stand-alone or in combination with the rear drive MF3 Laser Rear.
The highly precise gear and the direct power transmission in combination with the fast and digital motor control using the new eBOX make up the centerpiece of the MF3 Laser. The 2x2-roller principle guarantees minimum slippage and prevents deformation of the wire as a result of pressure forces. The short acceleration and response times, which are important for laser applications, can therefore be achieved.
The drive/specification speed is monitored and controlled by a built-in encoder. In addition, the actual wire speed is determined with the aid of the actual value transmitter for the wire and forwarded to the service software. The good accessibility and the quality of the wearing parts allow quick and easy replacement of wearing parts and thus reduce downtimes.
The advantages in brief:
- 2x2 roller drive
- Small size and light weight
- Monitoring of feeding speed by actual value transmitter (AVT) for the wire and service software
- Reworked pressure rocker for adaptation to increasing service requirements
- Easy and user-friendly handling
Wire feeding hose MasterLiner – for constant flow
The products in the MasterLiner series set new standards in wire feeding. They consist of individual segments, each of which can be rotated by 360°. Four small rollers in each segment ensure smooth wire feeding with virtually no resistance.
The MasterLiner system is available in the MasterLiner and the MasterLiner MAXI designs, each in the variants HD and FLEX. The flexible FLEX version – consisting of a corrugated tube and variable connection system – allows easy, free assembly of the desired length as well as unproblematic repair directly on site. This advantage saves time and therefore also money.
The heavy duty HD variant is sheathed in a resistant aramid fibre reinforced protective fabric and has been developed for extreme applications.
With the use of the roller-guided MasterLiner, it is no longer necessary to change electrodes – so timeconsuming maintenance work on the cable assembly is avoided. In addition to the improved process stability, further potential for savings is therefore realised and the system availability is significantly increased.
The advantages in brief:
- Low friction forces
- Long durability
- Can be cleaned by ultrasonic bath
- Maintenance free and low susceptibility to faults
- Wire feeding possible over long distances and with only one drive
- Can be used for all types of wire
- Easy, quick setup and replacement due to quick-release
Rear drive – additional power if required
For certain applications, it is recommended to operate the MFS-V3.1 system with a second drive, as a push-push system, to guarantee reliable processing of the wire feeding.
One essential criterion in the decision is the length and condition of the wire feeding route. In the case of long distances or even complex routes affecting the liner management, a rear drive is critical to guarantee an even feed. The properties of the materials used are also significant. Soft wires e.g. such as aluminium require two drives, preventing any tensile forces acting upon the wire; the wire is pushed evenly and not pulled undesirably over the length. With the additional drive, the forces acting on the individual components in the system are minimised and the wear is therefore reduced. The two drives are each addressed separately by the eBOX via their own control circuit, to keep the response times as low as possible. Synchronisation between the drives is therefore not necessary.
Furthermore, the wire buffer function of the system is new, which is controlled by the intake current of the rear drive. This ensures that the MasterLiner is refilled with enough wire after each cycle. This function guarantees even better wire feeding performance, particularly at the start.
MF3 Laser Rear
Being structurally identical to the front drive MF3 Laser, the MF3 Laser Rear includes also the positive characteristics of the “big brother”. The two are distinguished only by the actual value transmitter for the wire (AVT), which is not required in the MF3 Laser Rear and is therefore omitted.
The identical wear parts system makes it the perfect addition to the main drive.
Operating panel MF-Control – everything in view
The MF-Control operating panel is an optional component of the system and represents the mobile alternative to the system PC by which the MFS service software is usually controlled.
Whereas the system PC remains permanently installed and connected to a single eBOX in the system, the small, light operating panel is mobile and can be used flexibly for multiple eBOX devices, by plug & play via a CAN bus interface.
Furnished with a Windows panel PC, the MF-Control has a fine and precise touchscreen. With it, the full extent of the MFS service software can be used. In addition to the familiar functions such as process monitoring and fault analysis, further features that make the work of the user much easier are available via the operating panel.
All the eBOX devices used can be managed with the MF-Control. It is possible simply to change process parameters in job mode or to create new jobs in offline mode then to load them to the respective eBOX when a connection exists.
The MF-Control operating panel is therefore a helpful component of any servicing and maintenance department.
