01、What products can the equipment assemble? How many specifications are covered?
Dedicated to new-energy high-voltage DC contactors (relays), compatible with three series — NDZ3AT-150D, NDZ3AT-150G, NDZ3AT-250C — supporting multi-specification flexible common-line production.
02、Is switching product specifications troublesome? How long does it take?
Not troublesome. The three series share the same production line; changeover only requires replacing fixtures, grinding heads, and scanning to call up the corresponding process recipe, with no hardware modification needed and zero downtime waiting.
03、What are the advantages of laser welding the ceramic cover? How is air-tightness ensured?
Laser energy is concentrated, non-contact, with a minimal heat-affected zone, avoiding brittle ceramic cracking; the ceramic cover and Kovar alloy / electrical pure iron are laser-sealed by welding to form an airtight structure, complemented by vacuum evacuation and gas filling and helium mass-spectrometer leak detection, forming a complete high-reliability sealing chain.
04、How is welding quality ensured? How are non-conforming products handled?
Each welding unit is equipped with CCD online vision inspection, imaging and judging each weld point in real time; defective products are automatically rejected to the defective-product feed channel, strictly isolated from qualified products, eliminating the risk of mixing.
05、How about production cycle time and operating rate?
Dual laser heads + four-station rotary table allow 2 products to be processed in parallel per station; overall line cycle time as low as 12 s/piece, equipment operating rate ≥ 90%, reaching an industry-leading high cycle time level.
06、How is quality traced? Can it be located when problems occur?
Key assembly and inspection data are automatically collected and bound to the product QR code; scanning the code retrieves the corresponding process parameters and inspection records, achieving full traceability of each piece for quick location and improvement.
