Product of the month July: Special gripper for mini wave soldering processes

The selective soldering of assemblies in panels is not really a challenge. However, if you need to solder large panels with protruding components, you need to find a complex special gripper that can handle this challenge reliably.

The special gripper fulfils two tasks: it holds the components in position and also prevents the PCB from bending. Customer specifications defined that no bending force should act on the components. It was therefore necessary to feed the assembly absolutely straight into the respective processes. The special aspect here is that the panel arrived on the belt in the process cell without a workpiece carrier. However, as the component spacing was positioned too close to the belt, it was not possible to solder directly under the belt. The panel therefore had to be picked up from the belt. During pick-up, the PCB is pressed against a spacer from below and is therefore held absolutely straight in the gripper. The upright capacitors were also pressed against component-specific hold-down devices. The gripper then moves to the IW 1 mini wave soldering module with a specific soldering nozzle using an axis system.
