Rotary-table socket assembly cell

Rotary tables are popular solutions when it comes to automated assembly applications. We have recently designed and constructed a special robotic cell which is now able to automate a complex, fine-mechanical sequence of operations that previously involved meticulous and strenuous, monotonous human work with many potential for error. 

Our client is a Hungarian subsidiary of an international group engaged in the production and distribution of electrical installation materials, with excellent market positions and recognition. Their Hungarian subsidiary also operates as the group’s production and logistics center in Southeast Europe. In order to increase their production efficiency, the company decided to automate its socket production unit. An 8-position, rotary table assembly machine was dedicated to the line producing several product types. Given that there was no „ready-made solution” for the task, we relied heavily on our self-developed solutions in the project.

For the project we used 2 KUKA KR- series robot arms and built 5 manipulator units. The dosing of the parts is ensured by 4 individual vibrating dosing system. One of the robotic arms inserted a spring-assembled part into the product, while the other also placed spacers while unloading the finished products. The product inspection stations, on which we used camera and special tool inspectors, played a key role in the assembly system.

Main units of the project: 
  • robot arms - 1 x KUKA KR3, 1 x KUKA KR10
  • manipulators - 2 x 1 axial, 1 x 3 axial és 2 x 4 axial manipulators
  • sensors - 1 x camera examiner, 1 x stecker examiner
  • dosing - 4 x vibrating doser systems

The machine works with a cycle time of 5 seconds and can substitute the manual work of 5 workers who could have been moved to more valuable work positions.  
An additional benefit of the project was that we automated the insertion of a tiny spring which ensures the operation of the child lock. Due to the size of this part and the special way in which it was inserted, this task required a series of fine mechanical operations that meant very meticulous, strenuous, yet monotonous work when carried out with human workforce, with a high risk of faults.
