Detailed explanation of core functions and values
1. Automatic assembly of seat frames and foam cushions
The AGV transfers the seat frame to the production line, and the robot grabs the foam cushion, adjustment motor, and slide rail components, multi-axis synchronous tightening module locks the frame bolts, and servo press-fits the buckles to fix the cushion. It monitors the torque of each bolt in real time, and automatically alarms for missed tightening and torque deviation to isolate defective products.
2. Electric slide rail durability adjustment test
The servo simulates the seat adjustment instructions of the entire vehicle, and adjusts the seat front and rear, high and low angles 5,000 times, collects the motor operating current and slide rail sliding resistance, and identifies motor wear, slide rail jamming, and wire harness pull and break defects to avoid customer seat adjustment failures.
3. Visual inspection of foam cushion fit
A high-definition industrial camera scans the surface of the seat cushion to identify appearance defects such as wrinkles, offsets, missing materials, and damage. Defective products are automatically diverted for repair to ensure the appearance quality of the entire vehicle interior.
4. Full-dimensional verification of seat electronic control functions
Simulate the vehicle seat control switch signal, detect the response speed of heating, ventilation, and electric adjustment motors, verify the communication logic of the seat electronic control module, and intercept electronic control failure parts in advance.
5. Full-link digital traceability of seat parts
The RFID of each seat binding tray, frame bolt torque, motor current, slide rail durability data, and appearance inspection results are all uploaded to MES, which completely records the entire seat production process and meets the traceability audit requirements of IATF16949 for interior parts of the OEM.
Commercial value: After-sales failures such as seat adjustment jams and cushion wrinkles have been reduced by 91%. A single production line has replaced 8 assembly and inspection workers; the circular layout material transfer labor has been greatly reduced, and it is suitable for parallel mass production of seats for multiple car models.

Detailed explanation of core functions and values
Precision press assembly of motor stator and rotor | The servo press presses the stator and rotor components in a closed loop, monitors the pressing force and displacement curve in real time, and automatically alarms when the rotor is eccentric and the press is not in place; the robot automatically grabs the bearing, shell, and sealing gasket to complete the assembly and locking, eliminating bearing installation skew failure. |
Rotor online dynamic balancing automatic correction | After the rotor assembly is completed, it is sent to the dynamic balancing station. The equipment automatically detects the eccentricity, corrects the unbalanced weight by milling, and controls the dynamic balancing accuracy within 0.5g·cm to eliminate the source of jitter and abnormal noise in the high-speed operation of the motor. |
Power-on endurance performance test under load conditions | Simulate the load resistance of the vehicle's water pump and fan, and run the motor in a continuous cycle of start and stop for 30 minutes, collect no-load, load current, and output torque, and identify defects such as coil short circuit, bearing wear, and insufficient power. |
NVH silent noise detection | The workpiece is sent into a closed soundproof cabin, and the motor runs in all gears at high and low speeds to collect the noise spectrum. The system automatically compares the standard noise curve to accurately capture the abnormal noise of the rotor eccentricity and bearing friction to avoid motor noise complaints while the entire vehicle is running. |
Whole-process quality traceability of motor production | Each motor is bound to the casing QR code, and the press-fitting force, dynamic balance correction value, torque, and noise detection data are stored locally for 10 years. The docking with MES meets the quality traceability standards of vehicle-mounted motor parts of the OEM. Commercial value: After-sales faults such as jitter, abnormal noise, and insufficient power of the vehicle motor have been reduced by 93%. A single production line has replaced 6 assembly and inspection workers; the workstations can be split to adapt to small batch trial production of customers' new products, reducing initial equipment investment. |
