Welding/Cutting Auxillary Devices TRIZ Cases
- Stator Hairpin Laser Machining with Clamped Cut-and-Weld Alignment
Clamped hairpins are cut to equal height and laser welded in one flow, reducing misalignment, poor welds, and standby time.
- Laser Beam Shaping for Wafer Street Insulating Layer Removal
A stripe-shaped pulsed laser and polygon mirror remove wafer street insulating layers in one pass, improving throughput while limiting circuit damage.
- Battery Module Welding Fixture for Hanging Lug Positioning
Floating battery modules against lateral positioning surfaces improves hanging lug flatness reference and welding assembly accuracy.
- Pressure-Enabled Laser Control Unit for Operator Presence Safety
A spring-return cover panel enables laser motion and emission only under hand pressure, preventing uncontrolled activation when the operator is absent.
- Ultrasonic Conductor Welding With Retention to Limit Untwisting
A nearby retention device holds the first welded node so twisted conductors can be ultrasonically welded with shorter untwisting and better EMC.
- Spring-Loaded Clamping Plates for Reliable Battery Tab Welding
Spring-loaded clamping elements press busbar tabs onto cell terminals during laser welding, improving weld consistency while accommodating terminal variation.
