Automatic balancing to minimise vibration
In order to meet the high demands of "just-in-sequence production" in the automotive plant, maximum system availability and minimum cycle and changeover times of the automated production systems are required.
Application example: drive shafts
In four balancing systems realised by IBG, over 280 different types of car drive shafts with lengths ranging from 400 mm to 2,000 mm are removed from an electric monorail system, automatically balanced and then ejected from the automation cell.
After determining the unbalance of the drive shaft in another station of the assembly system, the unbalance correction weights are assembled on the basis of the measured data and automatically welded to the designated positions on the drive shaft by a robot. The robots used and the balancing system are equipped with extremely compact, servo-motor-driven holders so that the various cardan shafts, which are stored in a chaotic sequence, can be produced within a minute and the fastest possible automatic changeover to a particular shaft type can be carried out.
Application example: lorry wheels
The customised wheel balancing system for the automatic balancing of lorry wheels is equipped with reliable transfer technology and a specially adapted robot gripper. The lorry wheels are delivered as a stack and guided via roller conveyors into the robot's work area, where it positions them in the balancing system and automatically measures the wheels. At the customer's special request, the balancing weights are applied manually, with the position of the weights to be applied being precisely indicated by a laser. When the balancing weights are applied automatically, the weight is applied directly. After successful processing in the assembly cell, the wheels are stacked on top of each other again by a robot on a roller table.
Our system for balancing lorry wheels offers a decisive system advantage. Thanks to its flexibility and the use of high-tech components, a reliable automation solution has been created that enables 100% testing of the various products in the shortest possible time and is therefore highly economical and reliable.
