Work Package 4 : Developments of Technology Steps to Ease Circularity, Repair and Second Life

Lead beneficiary: I2M Laboratory

The dis-assembly process can have economical interest based on automated and robotic technologies. This WP focuses on the development of a proof of concept of an interactive automatic dis-assembly cell (including diagnostic, extraction and testing, repairing or recovery for second hand use) as illustrated in the illustration bellow. The technological constrains will enrich the WP2 formalization for product design improvement. Several type of information (based on WP3 and WP5 data) will identify the residual value evaluation (total PE converter, or by component), the dis-assembly process. This is the base of the digital twin of the PE system, including the design models, the manufacturing processes models, as well as the associated workflows enabling the successive steps to occur. Material and energy data are therefore associated with the virtual model process model or mock-up. The POC will demonstrate the PE component saving process thanks to

  • i) an interactive robot / cobot dis-assembly cell for PE
  • ii) a semi-automatic dis-assembly-repair process proposal (giving inputs for the constrains to integrate for PE design improvement)
  • iii) a digital twin of the robotic cell and PE to support human / robot interaction (using vision recognition, Augmented Reality or digital tablet) and identification of component to save or repair and operation and tolling, but also a visual ranking of the subsystem or component based on value evaluation in order to help the repair / recover / recycle decision making (best value options)
  • iv) a traceability and guaranty process to propose a quality-guaranty check for the repaired PE converters or the saved subsystems / components.

The residual value (product or component) should be defined regarding: i) value indicators, ii) assembly / dis-assembly. This is also based on the data on the product, its digital mock-up and the ability to guide the actions to get the components with residual value in a safe way. The main steps for End of Life operations are the mains action for VIVAE project.

WP4.1 action: POC

The proof of concept will be based on flexible operation cell(s) composed of automatic / semi-automatic / cobot / and manual actions (Recovery POC). It is based on the assessment of the product residual value evaluation, and will guide the process and operator to on the system (digital inputs will help the operator in the EoL process). The work in this section will:

  • define the criteria for multicriteria evaluation recovery vs recycle
  • design the process for product disassembly and component recovery, including the sequences of operations (manual or automatic)
  • design the tooling and product support, trying to be a bit standardized to support differ types of product EoL
  • design the information support to assist operators’ action in the cell configuration and operation (when relevant).

This section will interact with WP2 and the product standardization approaches. In addition, the Life Cycle Inventory of the End of Life process will be consolidated to enable the environmental impact assessment.

WP4.2 action: Qualification

The virtual qualification of the recovered component will be ensured by collecting all the information during the different End of Life operations. This will ensure the traceability for the diagnostic / dis-assembly / test phases and prepare the qualification of the 2nd hand components based on the literature in maintenance and failure domain for power electric systems (Data Base Qualification and virtual qualification rules). Some physical tests on components may also be necessary. The work in this section will:

  • review the models and criteria for component qualification in power electronic systems, and define the list of i) virtual and ii) physical qualification,
  • define the needed data to measure / capture during the EoL or test phases,
  • propose a data structure and rules (based on the literature) to support qualification and traceability on the components.
  • address the qualifications to the design for repair, re-manufacture and reuse guidelines, in an integrated manner for the targeted designers along the value chain (manufacturing, usage).

WP4.3 action : Data for Brokers

To access the marketplaces it implies to propose a data structure exchange for the power electric components for brokers identification (consumers or brokers Data). The work done in this section will:

  • review the list of characteristics for component and commercial performances,
  • propose an information structure that could be inter-operable with e-brokers solutions or market place requirements.
  • formulate the environmental issues for brokers to minimize wastes, energy and material intensive processes, generating unwanted damage or rebound effect during reuse scenarios within the brokers contexts.

Expected deliverables for the WP4

  • WP4.1 Flexible cell for product recovery and the information and on needed to run the EoL process,
  • WP4.2 Data structure for information collection to ensure virtual qualification of the recovered component,
  • WP4.3 Data structure for customers, broker or market place exchange.
