Assembly and testing technology

Assembly machine for control arms

This machine is used to press the rubber bushings into the welded assembly control arm. The main item of this equipment consists of a robot and a rotary table. The machine works fully automatically. The welded assemblies taken by the robot from a painting rack are deposited by the robot onto the rotary table. The assembled control arms are removed by the robot and deposited onto pallets in blister foils. On the rotary table there are stations for painting and weld seam inspection, for pressing in of the bushings, for type identification and labeling of the components. Also part of the machine is a sorter, a feeding for the bushings, an intermediate storage, a discharge station for manual parts removal (drawer system with 14 supports), an ejector belt for NOK parts and a destacking station for the finished OK parts.
