Context

Mimotec SA, a renowned Swiss company specializing in electroforming micro‑precision parts for the watchmaking and industrial sectors, has been operating an automated industrial vision quality control device since 2016 to inspect its production. This machine, commissioned in 2016, was built on an aging computer architecture that now relies on obsolete components and control boards.

Retrofit the control system of the 2‑axis motorized table and provide high‑performance vision software.

Replace the PLC, sensors, and actuators responsible for precisely moving the 2‑axis table and camera. Provide an industrial vision solution incorporating Deep Learning technologies. Improve the user interface. This modernization made it possible to:

  • Significantly reduce the time required to program a new inspection recipe
  • Resolve hardware obsolescence issues
  • Modernize the interface and enhance device usability

Deliverables

Alps Group developed a new PLC program for the motorized elements and created new industrial vision software with a custom graphical user interface. To successfully complete the project, the team performed:

  • Electrical redesign and modification of the machine, integrating Beckhoff hardware
  • Creation of a new user interface using Wonderware
  • Development of new vision software with Deep Learning based on Cognex technology
The retrofit project for the vision‑based quality control machine went very smoothly. All technical objectives were met as expected, and the implementation proceeded seamlessly. Alps Group was present throughout the project and demonstrated strong responsiveness to various requests and adjustments. Communication and exchanges with the project manager and technician/developer were always constructive, facilitating decision‑making and project progress. This effective collaboration contributed to the smooth execution of the retrofit and the overall success of the project.
