Production system challenges

●As more electric vehicles are produced and consumer needs grow more diverse,
there is a need to shift from mass production to variable-mix / variable-volume production

Development concept　ｰAreas where robots are put to useｰ

●A flexible production line that supports variable-mix / variable-volume production.
●Using collaborative robots to achieve both productivity and safety, while automating assembly work with tracing.

Solution

Flexible production lines

Developed with the goal of a flexible production line that can handle product changes and workloads

Unit configuration

Units are designed around COBOTTA PRO and configured to support multiple processes

Utilization of AMR

Process rearrangement following a product or work change is performed by relocating units using AMRs.Units are designed to be for plug-and-play so that they can begin operating immediately after being relocated

Relocating units

When relocating units, cameras are used to scan markers that to automatically correct the relative positions of robots and workbenches, with no need for reteaching

Robot hand tool change

All COBOTTA PRO hands are standardized, allowing for smooth tool changing between different processes

Using collaborative robots to achieve both productivity and safety

COBOTTA PRO is one of the fastest collaborative robots currently available.Accelerates and decelerates quickly, reducing takt time and enhancing production efficiency Can operate without a safety fence, making equipment layouts more flexible.Switches to collaborative operation when near humans, enhancing safety.Switches back to high-speed operation away from humans, enhancing productivity Can switch operation speed based on site conditions.

COBOTTA PRO contains a force sensor built into the robot arm

COBOTTA PRO contains a force sensor built into the robot arm to obtain external force values.Values obtained by the compliance function with the force sensor can be used to carefully adjust pressing force, in order to perform imitated assembly work.This allows for highly difficult assembly work to be automated, without needing to attach a force sensor to the robot hand
