Single-phase rail-mounted energy meter automated assembly and testing production line

1. Automated assembly function
PCB board automatic processing
Accurate placement of circuit board components is accomplished by automatic mounter (SMT), and optical inspection (AOI) is used to ensure the quality of welding, avoiding false welding or misplacement.

Robotic assembly
Robotic arm with vision positioning system to complete the accurate assembly of terminals, current transformers, housings and other components, reducing the error of manual intervention.

Screw auto-locking
Servo motor drives the screwdriver to fasten the screws according to the preset torque and position to ensure the structural stability.

2. Intelligent testing function
Electrical parameter test
Automatically connect to standard load, test voltage, current, power factor and other parameters, the accuracy can reach 0.5 level (in accordance with IEC 62053 standard), and the substandard products are automatically rejected.

Communication Function Verification
Analog RS-485, infrared or wireless (e.g. NB-IoT) communication, calibrate data acquisition and transmission stability.

Safety insulation test
High voltage tester for voltage withstand (e.g. 2kV/1min) and insulation resistance test (>100MΩ) to ensure product safety.

3. Data Management and Traceability
MES System Integration
Each meter is bound with a unique QR code, which records the production batch, test data, and operator information, and supports full life cycle traceability.

Real-time quality analysis
SPC (Statistical Process Control) system monitors the fluctuation of key parameters and warns potential process problems in advance.

4. Efficient Logistics and Packaging
AGV Material Distribution
Automated Guided Vehicle delivers shells, cables and other materials according to the beat, linking with the production line to realize JIT (Just-In-Time) supply.

Automated Packaging
Robot loads the finished products into shockproof foam boxes, automatically labels and scans the code into the warehouse, and the packaging speed can reach 300 units/hour.

5. Flexible Production Design
Quick Changeover (SMED)
With modular fixtures and program switching, it can be adapted to different models (e.g. 5(60)A, 10(100)A, etc.) within 30 minutes.

1、Equipment input voltage 380V±10%, 50Hz; ±1Hz;

2、Equipment compatibility: State Grid/South Grid, single-phase energy meter series, three-phase energy meter series.

3, equipment production beat: 30 seconds / unit, and can be customized according to customer requirements.

4, the same shell frame products, different poles can be switched by one key or sweep code switching; switching different shell frame products need to manually replace the mold or fixture.

5、Assembly mode: manual assembly, automatic assembly can be optional.

6、Equipment fixture can be customized according to the product model.

7、Equipment with fault alarm, pressure monitoring and other alarm display function.

8, Chinese and English version of the two operating systems.

All core parts are imported from Italy, Sweden, Germany, Japan, the United States, Taiwan and other countries and regions.

10、Equipment can be equipped with optional functions such as “Intelligent Energy Analysis and Energy Saving Management System” and “Intelligent Equipment Service Big Data Cloud Platform”.

11、It has independent independent intellectual property rights.
