Features:

  • Guidance Technology: Magnetic bar
  • Capacity: 6,000 lbs./2,727 kg.
  • Safety: Safety scanners, safety bumpers, Rockwell safety PLC
  • Controls: Rockwell open architecture, vehicle management system (VMS)
  • Keys to Success: Vehicle synchronization, custom designed chassis, high capacity lifts
  • Results: Improved flexibility, decreased infrastructure, elimination of batteries and chargers

Chassis marriage has traditionally been completed with a Rail Guided Vehicle (RGV) and in floor track. The system has been a longstanding robust and reliable solution; however some customers require additional flexibility to support their process.

The chassis marriage AGV looks to improve on the RGV technique by utilizing induction power. Using induction provides a limitless power source and magnetic guidance which is a proven guidance technique for AGVs providing a high level of reliability and accuracy.

One of the main design considerations for the chassis marriage AGV development was flexibility and infrastructure reduction. Utilization of an in floor induction wire and magnetic bar will decrease the cost and time associated with the installation of Chassis Marriage systems. The ease of layout changes supports the added flexibility requested by the end users of these systems.

Automated Guided Vehicle for Automotive Chassis Decking Line

Fori recently provided a precision battery powered automotive Chassis Marriage AGV for an electric car manufacturer.

Features:

  • Guidance Technology: Magnetic tape or bar
  • Capacity: 4,000 lbs./1,818 kg.
  • Safety: Scanners, bumpers, system interlocks
  • Controls: Allen Bradley Open Architecture
  • Keys to Success: Custom designed chassis, accurate and repeatable
  • Results: Increased flexibility, decreased infrastructure

Fori has traditionally supplied Rail Guided Vehicles (RGVs) for automotive Chassis Marriage, but over the past five years Fori has leveraged its AGV experience to transfer existing automated vehicle technologies to its Chassis Marriage systems. The automated vehicle technology provides a Chassis Marriage system that decreases the required plant infrastructure. Whereas the traditional RGV based system requires an in floor track and power transfer system. The AGV system removes this requirement by utilizing an on board, battery based power supply and magnetic tape or bar guidance for vehicle tracking and positioning. Overall these improvements decrease facility work and associated cost, and allow for decreased installation times and provide long term flexibility for changing production needs.

The battery powered Chassis Marriage AGV includes dual independent Fori patented chain lifts capable of lifting and transporting 4,000 pounds in order to install the front and rear suspension and drive train modules to the vehicle Chassis. The battery based Chassis Marriage AGV was developed to support the end users lean automated manufacturing methodology, decreasing the total in plant infrastructure required for the system. Not only will the AGV enable the end user to reduce their plant hardware investment, there will be significant long term flexibility in the assembly process. The guidance system of the AGV and reduced plant infrastructure allow the AGV to easily interact with other systems and processes.

The AGV is outfitted with multiple safety measures that ensure collision avoidance. Safety scanners are included on the front and rear of the vehicle that will slow down and stop the vehicle as objects enter the scanning field. The Chassis Marriage AGV also includes indicator lights in each corner, (4) e-stops, safety pressure bumpers on the perimeter of the AGV and an on board HMI for vehicle status and diagnostics.

Automated Guided Vehicles (AGVs) for Automotive Chassis Marriage

Fori recently supplied a custom designed Chassis Marriage Automated Guided Vehicle (AGV) for an electric vehicle manufacturer.

Over the past twenty years, Fori automation has been a leader in Automotive Chassis Marriage. Chassis Marriage, the process of bringing the car body and chassis together, has been primarily completed with the use of Rail Guided Vehicles (RGVs).

The Chassis Marriage process is completed utilizing integrated lifts and custom tooling pallets to support various chassis depending on the model of vehicle being manufactured. The Chassis Marriage process is completed once the operator does a final torque of fasteners, bringing the car body and chassis together.

Fori - Automated Guided Vehicle (AGV) for Chassis Marriage
Fori Automated Guided Vehicles (AGVs) provide increased flexibility and reduced infrastructure versus traditional Chassis Marriage methods.

The utilization of Automated Guided Vehicles (AGVs) for Chassis Marriage has increased flexibility for the end user by removing the monuments that are required on RGV based Chassis Marriage systems. The Chassis Marriage AGVs utilize a number of different power sources and guidance methods. Power sources include both lead acid and lithium ion batteries, induction and some cases a combination of both battery and induction power. Guidance can be completed in a number of ways, the guidance systems utilized most frequently are magnetic guidance, induction or optical.

Each Chassis Marriage AGV includes (2) integrated Fori electric lifts that are used for raising the drive train of the vehicle to the body. Each lift is capable of lifting up 2,500 kg. and upon request can reach lift strokes of up to 52″ depending on the project requirements.

Utilization of AGVs within Chassis Marriage has resulted in increased system flexibility, decreased plant infrastructure for the end user and has provided a scalable solution allowing for addition of vehicles based on expected production rates.
