1. Product categories used for testing or production, product speed and torque and other parameters
· Product category: New energy drive motor assembly (adapted to multiple models, including platform products such as 324001, 324006 and their derivative deformation products).
· Key parameters:
o Speed: The peak requirements are not specified, but the assembly process needs must be met (specifically guaranteed by tooling adaptability).
o Torque: Not mentioned directly, but the equipment needs to support high-precision tightening processes such as servo pressing (tightening torque error ≤±3%).
2. Main functions of the equipment
Function 1: Fully automatic replacement assembly
supports the selection of product models through the server, automatically calling processing parameters and completing tooling switching (the replacement time is ≤20 minutes), and is compatible with expanded products with different outer diameters (220~270mm) and 1.5 times the outer contour size.
Function 2:
Integrate visual inspection, airtight testing, and EOL testing systems with high-precision quality detection and traceability to realize key process data collection (R&R≤10%), defective product isolation and two-way quality traceability (query by flow number and batch number).
· Function 3: Intelligent production management
is equipped with a MES system interface to monitor equipment status, output, and alarm information in real time, and supports process parameter encryption storage and one-click replacement functions.
3. Dynamometer parameters of the equipment
Note: The independent dynamometer is not explicitly mentioned in the technical agreement, but includes EOL testing systems (such as Chengbang and Langdi brands) for final performance verification.
· Associated parameters:
o Torque: Verified by servo press (such as Panasonic and Yaskawa brands, pressure-displacement monitoring).
o Speed: adapts to the motor's rated speed range (specifically defined by product drawings).
o Brand: The test system supplier is a domestic first-tier brand (such as the EOL test power supply uses Cowell and Aino).
4. Production capacity, beat and other information
· Production beat: ≤11 minutes per piece (including loading and unloading, assembly and accompanying plate running time), the unbalance rate between stations is <15%.
· Theoretical production capacity: about 55 pieces per hour (calculated based on 8 hours of single shift).
· Reserved upgrade capability: By adding stand-alone equipment or operators, the beat can be increased to 6 minutes per piece.
· Pass rate requirements: The pass rate of downline is ≥98%, OEE ≥85%.
5. Other core features of the equipment
Modular and high reliability design:
o Adopt standardized modular structure (such as PLC, HMI, servo motor and other brands compatible), supporting rapid replacement of consumable parts (such as sensors, contactors) and maintenance.
o Key components (rail screws, pneumatic components) are selected from internationally renowned brands (HIWIN, SMC, Festo), MTBF ≥8 hours, and the overall life of the equipment is ≥5 years.
· Intelligence and security:
o Equipped with multi-level safety protection such as three-color LED signal lights, safety gratings, emergency braking buttons, etc., and complies with ISO safety standards.
o Material tracking is realized through RFID and barcode scanning, and real-time interaction and alarm management of production data are realized through MES system.
· Environmental adaptability:
o The working temperature range is -10℃~+40℃, humidity is ≤95%, and the anti-interference ability is strong (strong electricity and weak electricity are separated wiring), meeting the needs of continuous operation for 24 hours.
