Automatic nail-blowing and tightening

For the automotive industry, the assembly of engines often requires many bolts to be tightened. When we visit the production site we can see that on the engine assembly line there will be a lot of tightening guns hanging around. As there are many different types of bolts on the engine, some large bolts need to be tightened in advance, while some small bolts can be tightened directly. To ensure that the tightening strength meets the process requirements, automatic tightening guns are employed to ensure a satisfactory
tightening rate.

Solution

By assessing the size of the bolts on site, we found the scenario suitable for automatic nail blowing tightening. The bolts are first placed in the feeder, the vibrating discs screen the bolts neatly in turn, then the nail blowing equipment blows each bolt through the pipe to the end of the tightening gun, which is ejected by the tightening gun batch head to tighten the side of the engine. Automatic nail blowing for small bolts enables fast tightening and eliminates the need for advance bolting. In combination with the multi-collaborator arm, multi-angle, multi-position and small space tightening operations can be achieved. Free deployment of the robot according to the site space, while ensuring the assembly accuracy and guaranteeing the work beat speed.
