Increase process reliability, save time

Automated lubricant dispensing system optimises production processes in the automotive industry

Automated production processes in the automotive industry have to meet a variety of requirements. These include high process reliability and reproducibility or the documentation of dispensing processes and quantities. Efficiency and economy also play an important role. A frequent request from customers is therefore to optimise the application process, reduce the application time and thus increase the number of cycles. This was also the case here.

At a European automotive company, DOPAG configured an automated metering system for the application of lubricants. The special task: two different types of grease should be applied to automotive components at several points. Some of the areas are difficult to access.

 

Process-reliable application of lubricants in the automotive industry

All of DOPAG's metering components are modular and can be individually configured. In this case, the experts from DOPAG have attached two needle dispensing valves to an industrial robot in order to flexibly apply the two greases in several places. The material is applied contactlessly from different distances. In doing so, the robot enables a high degree of flexibility. Needle dispensing valves dispense the material very precisely and reliably. The material is discharged continuously as pressure-time dosing, the shot quantity is flexibly adjustable. 

The material is fed via two drum pumps for 30-litre drums. Thanks to the compact design, the material feed does not take up too much space, and the drums can be changed quickly and easily. Two material pressure regulators reduce the pressure of the conveyed material to the required working pressure and reduce pulsations. A stable material flow is ensured.

Lubricant dispensing system configured by DOPAG: two needle dispensing valve for the application of the two types of grease, material pressure regulators and drum pumps for a clean material feeding. 

DOPAG configured and provided the entire system including the robot for the customer. This was done in close cooperation with the customer's automation specialist. With the new dispensing system, the application per component can be carried out in only half the time. Twice as many components can now be greased. The reproducibility is more than 98 percent. This has also resulted in higher precision during application and greater reliability.
