Reis Robotics has developed a compact welding cell that is mobile yet fully enclosed. It is a “plug and play” design that assembles in 30 minutes for affordable robotic welding — even for short production runs. It is adaptable for MIG/MAG (with digital current source), TIG, or plasma welding, and features an operator-friendly controller for process data acquisition.

The cell is fitted with the Reis RV10-6 welding robot and the high-capacity RobotStarV controller, plus two freely programmable additional axes that are mounted immediate use, as necessary. All power supply, exhaust, and safety devices are integrated into the cell, so no peripherals are needed. It occupies 10 m2 (32.8 ft2) of floor space, so it’s simple to integrate to most operations.

The cell consists of a 6-axis Reis vertical articulated arm robot, which may be arranged upright or suspended overhead. The RV10-6 has a payload capacity of 6 kg (13.23 lbs) and a repeatability of 0.05 mm (0.002 in.), and was designed for complex path tasks. Due to its rigid construction with enclosed drive elements, it can operated in extreme plant conditions.

The RV 10-6 requires only minimal maintenance, according to Reis.

Both the robot and its rotary table are mounted on a common transport frame, and the safety cabin is mounted on this frame, too.

The manual rotary table is equipped with two mounted head-and-tailstock turning devices, with a 1,200-mm separation between the tips and a payload of 100 kg. Using these turning devices, the components can be optimally positioned to the robot, with separate control of these seventh and eighth external robot axes. This allows the robot to move synchronously with the freely programmable peripheral axes, and ensures that the welding torch moves at constant speed.

As the robot welds workpieces in one station, finished parts can be unloaded at the other station and new parts can be loaded. It’s also possible to arrange the cell to weld different components in alternating stations, creating greater flexibility and a higher production capacity.

Due to integrated synchronization of the table position with reference to the robot, even different programs may be processed on alternate sides. The various options are simple to program and contribute to lower operating costs. Due to a specialized bearing the workpiece carrier plate is easy to move, minimizing the strain on the operator. “With this rotary table concept, complicated and expensive safety equipment becomes redundant,” according to the developer. “Light barriers, step mats, swing doors, and two-hand operations thus can be omitted.”
