EV High-Voltage Discharge Connector Automatic Assembly and Inspection Line is fully automatic / semi-automatic assembly and inspection equipment for volume production of traction-battery high-voltage discharge connectors. The line uses a flexible layout of “manual pre-assembly + automatic processing + in-line inspection” and is divided into 10 main stations (OP10~OP100). It integrates core processes such as automated pre-assembly, precision soldering, heat-staking welding, in-line performance inspection and laser marking traceability, covering the complete process from loose-part loading to finished-product packaging and delivery, and meets strict requirements for electrical reliability, sealing consistency and production traceability.
OP10–OP100 in series, from loading to finished-product packaging.
Low contact resistance; structural strength and sealing ensured.
Insertion/withdrawal force and electrical performance verified.
5 models mixed; all parameters bound to MES.
Parameter | Value |
Number of stations | 10 main stations (OP10~OP100) |
Cycle time | ≤ 60 s/pc |
Product compatibility | Free switching and mixed-model production of 5 product models |
Line manpower | ≤ 4 operators (excluding positions related to product E) |
Compressed air supply | 0.5~0.7 MPa, with digital pressure monitoring |
Noise control | ≤ 75 dB |
Power supply | Three-phase five-wire TN-S; 3-phase 380V ±10%, 50Hz |
Core processes | Automated pre-assembly, precision soldering (OP30), heat-staking welding, in-line performance inspection (OP60), laser marking traceability (OP90) |
IT configuration | Data acquisition and communication interfaces as standard; can be connected to the workshop MES system |
Quality control | Quality gate mechanism; non-conforming parts do not pass to downstream processes; 100% conforming parts leave the line |
Safety protection | Automatic alarm and shutdown if the air supply pressure exceeds the limit or drops below the set value |
Traceability method | Laser marking assigns a unique code; supports forward/backward quality traceability |
