Customer

International Company specialized in innovative intracranial electrode development and production

The Smart-Benches are installed on a line located in a new facility dedicated to intracranial electrodes manufacturing

The equipments feed the parts, weld, perform an encapsulation by glue micro-dispensing and electrically test around 35'000 electrodes per year

The Smart-Benches was acquired to:

  • Ensure the reliable manufacturing of a new product in a new facility
  • Automatize complex and high-precision tasks, that are difficult to carry out manually
  • Improve and strengthen the processes repeatability
  • 100% test the products at each production step

Project main requests and constraints

Product variants

  • Lengths to handle = 15 to 80 mm
  • Number of contacts to encapsulate = 4 to 15

Highly sensitive and fragile components:

  • Connection wires Ø = 70 μm
  • Flexible parts
  • High added value product

Automated product variant change by vision

Cleanroom class 5


Equipment main requirements

Manual loading of the main component validated by vision system

  • Control of the component correct positioning inside workpiece-holder
  • Contacts location and number control
  • Verification of the correspondence between the loaded component and the work-order/recipe

Thermocompression welding

  • Force and position control (to ensure welding quality and strength)
  • Welding vision control (Wire breakage detection)

Electrodes insulation

  • Contactless glue micro-dispensing by jetting (contactless = to avoid any risks of product degradation)
  • UV curing
  • Vision control of the encapsulation quality
  • Electrical test

Manual unloading and packaging of the finished product
