Industry 

Lapptec produces cable glands, among other things. A cable gland consists of a connection piece, a seal and a terminating nut. These are available in various sizes. Lapptec wanted to produce all versions on one system.

Starting point

For the various sizes, different chicanes and outlets were produced as interchangeable parts for the feeder bowls. A separate interchangeable part cabinet was provided for handling all the interchangeable parts, in which all can be cleanly placed. The connection pieces come from this lying down, its alignment detected by a camera, and this information is passed on to the next handling unit. This handling unit places the connection piece on the linear transfer system in the cavity for the corresponding connection piece. 
A ram presses on the fins, so that the next seal can be better placed in the connection piece. The seals are fed standing up. The seal is pressed onto the connection piece with a handling unit with an additional pressing axis. The next camera detects the depth and presence of a sealing ring.
A screwdriver then screws the nut onto the connection piece. The depth is defined via a slide, which serves as a stop. Another camera detects the presence and screw-in depth of the nut. In addition, as a final check, the color of the connection piece and nut are checked for correctness. Finally, the assembled cable gland is removed via a handling unit and is deposited on the corresponding chute (OK or NOK).

System overview

A powerful and flexible feeder unit can be realized with the combination of a spiral conveyor system and a vision unit.

Feeder with integrated vision system

With the linear transfer module (LTM), the assembly parts are transported to the individual process stations.

Linear transfer module

The parts are inserted correctly positioned in the linear transfer module via the electric handling units.

Handling

The connection piece is previously expanded so that the seal slides into it better.

Expansion of the connection piece

The seals are put into the correct position by means of the chicanes in the spiral feeder bowl so that they can flow into the process.
