They are well suited for assembly and joining applications with force-distance monitoring and can be integrated in automated assembly lines, test stations or manual work stations. The units cover a force range from 10 to 200 kN.

The Line5 universal joining module is robustly designed thus making it well suited for heavy duty cycles. The units use an inline design, i.e., the shaft is driven by a motor spindle in line with the shaft. The excellent rotational characteristics of this system provide excellent dynamic response. The mechanical system consists of the following components:
Advantages of the mechanics:
Modular and networkabel
The mechanics are triggered via a power amplifier with integrated NC-module. The risk processor fitted in the NC-module takes over the control and monitoring of the assembly unit. It can be programmed comfortably and easily with PROMESS software using a commercially available PC and thus guarantees the user the highest operating comfort as well as maximum reliability.
The force-distance course can be monitored by envelope or windows functions. Quality control data and press programs can be stored via the data base plug-in and can be used again at any time. The system features a digital pre amplifier that transmits the force signal trouble-free with a resolution of 24 Bit. The calibration by measuring map allows for a very high accuracy of the force measuring and replaces the switchover of measuring ranges.
ADVANTAGES OF THE CONTROL
Intuitive and flexible
The UFM Software V5.XX features a transparent interface which provides simple operation. An integrated user administration with password input and rights management provides for quality assurance and traceability of the production process. The extended data base supports the server based systems SQL Server and Oracle.
New query and filter possibilities of the DB-Viewer display the requested records. Programs and editing can be stored and ever used again so that changes in the program can be retraced at any time. The real time envelope test allows for an immediate stop of the press in case of the limits being broken. The monitoring of the limit curves and the setting of the status are carried out in real time. The force-distance course can be monitored by envelope or windows functions
Process monitoring & force-displacement monitoring
For optimum monitoring of the joining process, PROMESS offers its universal joining modules with integrated process monitoring. The mechanics of the electromechanical NC joining systems are controlled via a power amplifier with integrated NC module. The control system in turn combines the force-displacement monitoring of the joining process and the motion control of the press mechanics. The joining process can be visualised on the screen and monitored by means of envelope curves, monitoring windows, measurement variables and thresholds. All process data is stored in a database and can then be analysed and evaluated. Alternatively, process, component and worker information can be transferred via field bus.
The basic idea of envelope technology is the monitoring of a signal curve, such as force-displacement, force-time or similar, by means of a freely editable upper and / or lower limit curve. Normal process fluctuations are tolerated, sudden disturbances are detected. The envelopes monitor the force-displacement curve over the entire press-in range. If the upper or lower envelope curve is violated, a NOK is issued for the joining process. The envelope curve technology integrates all elements of the window technology and structurally simplifies the monitoring of joining processes.
It is a prerequisite and basis for a technically sophisticated data analysis that uses all basic data - i.e. the measurement curves and limit values. The envelope curve technique offers a far more flexible adaptation of the limits than the window technique. The envelope curves can be set in the teach-in procedure (teaching) and subsequently adjusted.
When monitoring the joining process using the window technique, a defined area of the recorded curve is monitored. For this purpose, a rectangular window is defined and then it is determined where the curve should enter and exit the window. If the curve deviates from these definitions, the part to be added is marked with NOK. Envelope curve technology and measuring windows can be used in combination in process monitoring.
With the help of the PROMESS UFM V5.xx operating software, all process data is stored in a database and can be analysed, evaluated and exported to MS Excel via the database software plug-in DB Viewer. Optionally, standardised interfaces to QS-STAT and IPM are available for further analysis of the joining process.
