An OTC DAIHEN CUBE system is a standardized robotic cell for automated welding production. This compact system solution combines a robot, welding technology, positioning technology, control system, and safety technology in a ready-to-operate system. With various CUBE versions available, the solution can be adapted to different workpieces and production requirements.

OTC CUBE systems combine automated robotic welding with a compact and standardized system design. They are designed for efficient welding production in cycle operation and, depending on the version, support different positioning and workpiece concepts. This helps achieve high productivity, reproducible processes, and efficient use of the available production space.

The CUBE series is available in five versions: CUBE 01, CUBE 02, CUBE 03, CUBE 04, and CUBE 05. The versions differ primarily in their positioning technology – ranging from fixed worktables and a 180° indexing table to horizontal rotary positioners and 2-axis rotary/tilting positioners.

CUBE 01 features two fixed tables for mounting clamping fixtures. CUBE 02 uses a motor-driven reversible 180° indexing table. CUBE 03 is equipped with two horizontal rotary positioners, while CUBE 04 uses a 2-station horizontal rotary positioner. CUBE 05 features two 2-axis rotary/tilting positioners, providing additional flexibility for workpiece orientation.

OTC CUBE systems are suitable for automated welding production in industrial manufacturing environments. Thanks to the different positioning concepts, both smaller and larger workpieces as well as various component geometries can be processed. The appropriate CUBE version depends on the workpiece, payload, cycle time, and requirements of the respective welding process.

As standard, CUBE systems include an industrial robot, a welding power source, welding equipment, positioning technology, a control cabinet, and the required safety technology. This brings together the essential components for automated robotic welding in a standardized system solution.

OTC CUBE systems are designed to be particularly space-efficient. OTC DAIHEN specifies a footprint of approximately 2.2 × 4 meters for the CUBE solution. This makes it possible to implement a high-performance automated welding cell within a comparatively compact production area.

The possible payload depends on the selected CUBE version and positioning technology. Payload classes of 250, 500, and 1,000 kg are available for various positioner configurations. When designing the system, the workpiece weight as well as the clamping fixture, dimensions, center of gravity, and specific application must be taken into account.

In cycle operation, the individual work steps are organized so that welding and auxiliary times are coordinated as efficiently as possible. Depending on the system configuration, for example, a workpiece can be processed at one station while the next workpiece is already being prepared at another station. This helps reduce downtime and increase productivity.

Depending on the system configuration, solutions with multiple robots are also possible. This allows complex welding tasks to be divided between robots and processing times to be optimized. The most suitable robot configuration depends on the component geometry, weld seams, required cycle time, and production volume.

Yes. Offline programming with a digital twin is available as an option for OTC CUBE systems. This allows robot programs and motion sequences to be prepared and simulated virtually. It can help move programming work outside of ongoing production and reduce downtime on the actual system.

A digital twin creates a virtual representation of the robotic cell and enables the simulation of robot movements and production processes. Programs can be prepared, motion sequences can be verified, and potential collisions can be identified before the programs are transferred to the actual system. This supports efficient planning and programming of welding production.

The appropriate CUBE version depends on the specific welding task. Important selection criteria include workpiece size and weight, component geometry, required positioning movements, production volume, cycle time, and the desired level of automation. Based on these factors, the appropriate combination of robot, positioner, and welding technology can be selected.

A CUBE system is particularly suitable for companies looking to automate repetitive welding tasks and increase their production capacity. Thanks to their standardized and scalable system structure, CUBE systems are especially well suited for series production and applications with high requirements for productivity and reproducible welding processes.
