AUTORIV A240-BI: Stationary robot workstation – joining processes
The quality of the fastener to be processed limits or maximizes the possibilities of automation.
A fastener that is optimally matched to automated processing ensures extremely high availability. For this reason, AUTORIV® consistently offers fasteners, designed to f it the associated automation.
The AUTORIV A240-BI robot workstation stands for a fully-automatic, process-safe and high-quality processing of blind rivet nuts and blind rivet bolts with thread sizes M5 to M10 for nuts and M5 to M8 for bolts.
Variable connections in thin and thick sheet metal or plastic:
Blind rivet nuts (N) of the AUTORIV-BI series with pilot hole in the component
Blind rivet bolts (S) of the AUTORIV-BI series with pilot hole in the component
The geometry of the nuts is available in round and hexagonal versions:
Outer diameter or head diameter is min. 10 mm to max. 22 mm
Total height min. 13 mm to max. 30 mm
The bolt elements are available in a round form:
The processable shank length of the bolts is max. 30 mm
The outer diameter of the head is min. 10 mm to max. 22 mm
In addition, AUTORIV® offers futher special elements for customer-specif ic applications.
Processable fasteners and sizes:
Blind rivet nut with round shank Blind rivet nut with hexagonal shank

AUTORIV A240-BI: Stationary robot workstation – Operation mode
The robot picks up the component to be processed and feeds it to the AUTORIV-BI.
The robot places the component on the blind rivet fastener.
The supervisory control clears the fasteners for insertion. The insertion process only starts when a fastener is in the inserting postion.
The feeding of the fasteners as well as the electrical components are located outside of the robot cell fence. The fasteners are fed into the feeding hopper with a large capacity.
An integrated displacement measuring system gives the start signal for insertion as soon as a fastener is in clinching position.
If deviations from these specif ied values (e. g. component thickness, height of fastener) occur, the insertion process is interrupted and an error message is issued to the super-visory contro. This basically eliminates the possibility of an incorrect insertion.
The insertion process is pressure-controlled. When the specif ied pressure is reached, an „OK“ message (insertion procedure successful) is issued. If the pressure is not reached, the system switches to lockout and forwards the corresponding signal to the supervisory control.
The positional tolerances of all blind rivet fasteners can be adjusted by AUTORIV®‘s patented active tolerance compensation system of up to max. +/- 0.5 mm.
Examples of possible applications:
Front and rear flap
Supporting part bumper
Battery console / battery holder
Fender bracket
Cross beam
Crashbox

AUTORIV A240-BI: Stationary robot workstation – Insertion unit
The AUTORIV A240-BI insertion unit is generally designed for the processing of blind rivet fasteners. The force is transmitted via a hydropneumatic pressure booster and a hydraulic cylinder.
The insertion unit sits on a frame made of solid aluminium prof iles. The frame contains the electrical components, the pressure booster as well as the pneumatic control elements and protects them from dirt or damage. Equipped with doors on both sides, a quick and easy access to the components is guaranteed.
Example: AUTORIV A240-BI insertion unit with options:
Standard Option
Controlled process monitoring(Quiry f inal pressure / end position and output OK / NOK)
AUTORIV insetion unit: Multi-position cylinder for loading position and working position
Insertion head: - floating (active x-y-tolerance equalization)
pressure booster
Controlled process monitoring: - indirect measurement method- visualized process evaluation

AUTORIV A240-BI: Stationary robot workstation – feeding system
The AUTORIV A240-BI insertion unit can only be used with an AUTORIV A000 feeding system. The feeding system accommodates the control of the insertion unit and the interface to the supervisory control system. The feeding unit is installed outside of the robotic cell and is easily accessible. By means of various electromechanical processes, it stocks, sorts, and separates the fasteners. The fasteners are supplied to the setting unit by compressed air via a special tube. The available interface connections are hardware signals, Prof ibus, Prof inet, DeviceNet, and EtherNet/IP.
One feeding unit can supply up to two insertion units with the same fastener.

AUTORIV A240-BI: Process monitoring and process evaluation
The process monitoring of the AUTORIV A240-BI insertion unit can be carried out in different ways. Whether an insertion process was successful or not, is determined via the end position detection of the infeed and the f inal pressure in the hydraulic system.
In addition, the process evaluation via the control software of the operating panel is an option. A special monitoring-window function is used to set a successful insertion process as a reference.
As soon as a further insertion process matches the specif ied reference values, it is also evaluated as successful. The f inal pressure is measured via the pressure sensor on the hydraulic cylinder.

AUTORIV A240-BI: Stationary robot workstation – advantages
Extremely short cycle time
Since fasteners are loaded simultaneously to the insertion process, the loading time is not included in
the cycle time.
Active tolerance compensation
The active, patented tolerance compensation is possible thanks to a floating fastener that f its for all
blind rivet fasteners.
Active tool protection
The power stroke is only triggered when the fastener has successfully reached the component.
Compact design
Both the insertion unit and the feeding system have compact dimensions and can therefore be installed
in a space-saving manner.
Good accessibility
The positioning of the AUTORIV A000 feeding unit outside of the robot cell provides the best accessibility
for the operator and the service staff.
System technology from one source
The complete system incorporates experience and f ield-tested technology from more than 45 years of
development time. The innovative mechanics of the system ensure minimal susceptibility to faults.
