The Solution:

This machine needed to perform small part assembly with the highest precision. Our pre-engineered SDChassis offers the perfect machine platform for this high-speed application. With synchronized assembly and vision inspection stations, this machine is capable of producing high-quality electrical components in less than 2 seconds.

With a broad library of custom tooling already designed for a considerably small part assembly, our team was quick to adapt the designs for the SDChassis. Precision, accuracy, and repeatability are essential in this kind of application, and we have the capability to automate down to microscopic levels for this kind of electrical component assembly.

Results & Business Impact:

Results and business impact of an automated high-speed electrical component assembly machine

  • Increased Production Throughput: Produces one part every 1.2 seconds, significantly boosting manufacturing capacity.
  • Enhanced Product Quality and Consistency: Vision inspection systems ensure tight tolerances and reduce defects, improving overall product reliability.
  • Reduced Labor Costs and Manual Errors: A fully automated turnkey solution of complex assembly tasks reduces the need for manual labor and associated inconsistencies.
  • Faster Time-to-Market: Pre-engineered SDChassis platform enabled rapid deployment, shortening development cycles and accelerating product delivery.
  • Improved Operational Efficiency: Synchronized multi-station workflow optimizes part handling, reducing bottlenecks and material waste.

Operational Workflow:

The machine is built on the SDChassis platform, serving as the foundation for this high-speed automated machine. Custom nesting fixtures are mounted on a 30-station servo-driven indexing dial to support automated small part assembly. Each station securely holds and positions the intricate components that make up the electrical connector assembly. As the dial indexes, the parts move through a precise, synchronized workflow.

Each station is equipped with custom tooling to perform critical functions such as terminal cutting, forming, and small metal part insertion into the housing. Between operations, integrated vision systems conduct real-time inspections to track part orientation, verify assembly, and measure tight tolerances—essential for complex small part manufacturing. Once assembled, the completed component is picked from its nest and placed into an output bin, ready for the next stage of electrical component assembly.

This fully automated turnkey solution offers speed, precision, and consistency for manufacturers seeking to streamline small part assembly. It’s a powerful example of how an automated machine can transform production efficiency and quality in demanding applications.
