Line 2 Work Instruction (L1/L2/L3 Lamination, NG Punch, Row Cutting)¶
Version: v1.0
1. Purpose¶
Standardize lamination of L3 onto enzyme-treated L1/L2, marking of defective cells, and 30 mm row cutting & segregation.
2. Scope¶
Applies to semi-automatic Line 2 operations.
3. Equipment¶
- Lamination platform with pin positioning
- Hot press (120°C 0.4 MPa)
- Hot roll line (120°C 0.01 MPa)
- NG Puncher (defect coordinate execution)
- Row Cutter & Splitter (30 mm)
- Humidity Storage Cabinet (20% RH)
4. Inputs¶
- Accepted L1/L2 + enzyme assemblies (Line 1 output)
- L3 parts (decorative printed & dried)
- Defect map (Vision DB)
5. Procedure¶
| Step | Description | Detail | Record |
|---|---|---|---|
| 1 | Positioning | Place L1/L2 on platform pins | Batch record |
| 2 | Cover L3 | Align L3 using same pins | Visual confirmation |
| 3 | Hot press | Activate hot press 120°C 0.4 MPa (hold time define e.g., 5–10 s) | Press log |
| 4 | Hot roll | Transfer to hot roll (120°C 0.01 MPa) | Roll log |
| 5 | NG punch | Automated punch marks/removes defect cells (E1–E5) | Puncher DB |
| 6 | Row cut | Row cutter splits into 30 mm rows | Cutter log |
| 7 | Defect row segregation | Split rows: defect-free vs partial-defect vs full-defect | Physical label |
| 8 | Storage | Store ALL rows @20% RH (Good rows, NG rows separately) | Storage log |
6. Acceptance Criteria¶
| Parameter | Requirement |
|---|---|
| Lamination Alignment | ±0.1 mm tolerance |
| Adhesive Bond Integrity | No delamination on peel test sample |
| Defect Removal Accuracy | ≥99% of mapped defects removed |
| Row Dimension | 30.0 mm ±0.1 mm |
7. Defect Removal Verification¶
Sample 2 removed sites per frame; visually confirm electrode absence and no damage to adjacent cells.
8. Records¶
- Line 2 Batch Record
- Punch execution report
- Row segregation list (labels for "GOOD" / "PARTIAL-DEFECT" / "NG" containers)
9. Reaction Plan¶
Lamination shift >0.1 mm repeatedly: stop & recalibrate positioning pins. Punch misses >1%: verify DB sync & XY offset.
10. Safety¶
Hot surfaces: use thermal gloves. Moving parts: keep hands outside guard zones.
