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.

Customer Pain Points

Many workers are needed to do the tightening work in each sequence of stations. The work content of the workers is simple and repetitive. The priority for car companies in reducing manpower and cost-cutting aspects is the tightening stations and replacing manual labour with robots. Robots can better ensure qualified assemblies and avoid worker fatigue due to repetitive work, which can lead to missed jobs or assembly errors. Meanwhile, robots can work continuously 24 hours a day, greatly increasing productivity.

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. Guaranteeing stable production, production safety, production efficiency and production quality for your company.

Benefits

The solution can replace workers on three production shifts, helping companies save on labour costs, solve recruitment difficulties, ensure production stability and more. It also saves production beats and promotes overall productivity. Because of the safety of the collaborative arm, it also helps companies to reduce production accidents, improve their automation and ensure controllable product quality.
