Purpose of the Role
The Assembly Technician / Engineer is responsible for operating multiple systems for the assemble of pouch cells. The role includes handling electrode stamping, stacking, tab welding, pouch forming units, electrolyte dispensing equipment, sealing systems, and inline inspection tools. Strong focus is placed on precision, consistency, safety, and maintaining quality standards within a dry-room environment. Coordination with Electrode (Coating/Calendering) and Formation teams is essential for smooth production flow.
Key Responsibility Areas
Operating Assembly Equipment
- Operate electrode stamping (cutting) units
- Operate stacking systems to align and layer electrodes and separators accurately.
- Operate ultra sonic welding units
- Handle tab-joining and connection-preparation tools ensuring reliable electrical contact.
- Run electrolyte dispensing equipment with controlled and accurate dosing.
- Operate pouch sealing systems ensuring integrity and leak-free closure.
- Monitor HMI panels, process screens, safety indicators, and alarms for stable operation.
Material Handling & Preparation
- Handle electrodes, separators, pouches, electrolyte containers, and cell co
- mponents safely.
- Ensure correct orientation and order of parts entering the stacking process.Prevent contamination, deformation, or moisture exposure of sensitive materials.
Quality Checks
- Inspect sub-assemblies for alignment, visual defects, tab quality, and surface condition.
- Use measurement and inspection tools to validate thickness, dimensions, and sealing quality.
- Report variations such as misalignment, poor welds, leaks, or contamination.
Equipment Care & Cleanliness
- Clean fixtures, sealing heads, tooling, and assembly surfaces regularly.
- Conduct pre-start checks on alignment, clamps, vacuum systems, and inspection tools.
- Follow system shutdown procedures including securing parts and clearing material paths.
- Escalate equipment concerns to maintenance promptly.
Safety & Environmental Protocols
- Work strictly inside a dry-room environment with correct PPE and entry/exit rules.
- Follow safety practices for electrolyte handling, sharp components, heat zones, and automated systems.
- Maintain housekeeping to avoid contamination, chemical exposure, or equipment hazards.
Documentation & Coordination
- Maintain detailed logs of assembly parameters, batch numbers, and traceability data.
- Complete shift checklists and verify process adherence.
- Coordinate closely with the Electrode team for incoming materials and readiness.
- Work with the Formation team to ensure cells are transferred correctly for further processing.
Knowledge, Skills and Experience
Education
- Diploma in Mechanical / Electrical / Chemical / Production OR
- Engineering Degree (B.E./B.Tech) in related fields.
Experience
- 1–5 years of experience in precision assembly, battery cell manufacturing, or related continuous-process industries.
- Experience in dry-room operations is preferred but not mandatory.
- Exposure to automated assembly systems or HMI interfaces is beneficial.
Skills
- Good understanding of assembly tools, sealing processes, and handling sensitive materials.
- Strong adherence to quality, safety, and SOP guidelines.
- Good manual dexterity and attention to detail.
- Physically fit for standing, tool handling, and repetitive assembly work.
