This technological project involved all engineering areas of Selmatron, in order to conceive, develop and commission an automated system for pre-assembly of fire sensors, destined to the security systems industry.
The engineering team's briefing resulted in the technological project that preconized a system composed by a transport solution in a closed circuit, in which the manipulation of the components is performed by a 4 axis robotic system, promoting through a vacuum system, a positioning precision of +/- 0,02 mm and a manipulation of the component speed of +/- 3700 mm/s. With these positioning and manipulation indicators, the stipulated cycle time can be achieved.
The fastening of the components is ensured by a pneumatic screwing system, which guarantees the assembly of the PCB to the product, with torque values within the defined values.
The software component developed for this project has a "hybrid mode", which helps the maintenance procedures, allowing one station to be disabled and the others to continue the normal production process. This versatility promotes the reduction of the number and time of stops necessary for equipment maintenance.
The solution's infrastructure was projected to be mechanically prepared for the production of two products with distinct assembly processes, without impacting the mechanical arrangement of the elements.
Fabric conveyor belt, reinforced with stoppers and pallet indexing system, in the workstations.
4 axis robotized solution, with vacuum system, responsible for handling and positioning of all components.
Automatic screwing system in two positions.
This project result in a high performance solution, enabled by the optimization of all integrated systems.
With the automation of processes, it was possible to reduce workstations, previously assigned to manual processes, which are now automated.
The solution met the objectives previously outlined, achieving an optimization of the production process, with a 40% reduction in cycle time, compared to the existing system.
The versatility of the solution's mechanical component, enables the system to produce two different products, without requiring modifications in the mechanical setup.
