SIASUN New Energy Vehicle E-E Production Automation Solutions

In the NEV context, “E/E” typically encompasses high-volume, quality-critical products such as on-board chargers (OBCs), power distribution modules, electronic control units, and related test-and-inspection processes that must meet strict automotive safety and traceability requirements.

SIASUN Robot & Automation Co., Ltd. is a robotics and intelligent-manufacturing company founded in 2000 and commonly positioned as a provider of industrial robots and integrated smart-factory solutions. Within its NEV portfolio, SIASUN markets production automation aimed at improving throughput, repeatability, and data-driven quality control for E/E manufacturing—where small process deviations can translate into reliability issues, warranty risk, or regulatory non-compliance.

A representative example published by SIASUN is an OBC production automation line that integrates multiple stations and processes—assembly, gluing, rotating/handling, warehousing, and test—into a coordinated production system.

Design and Features

Integrated line architecture

SIASUN’s NEV E-E solutions are generally presented as line-level systems rather than standalone machines. In the published OBC case, SIASUN describes a production line composed of multiple functional segments, including:

• OBC assembly line

• OBC gluing line

• OBC test line

• Rotary warehouse (rotating storage/handling)

This structure reflects a common industrial pattern for E/E manufacturing: automate the “core assembly,” then automate repeatable secondary processes (e.g., adhesives or potting), followed by end-of-line (EOL) testing and buffer storage to stabilize takt time.

Modular configuration and scalability

SIASUN emphasizes modular design in the same OBC example, describing the solution as flexible for different customer needs and production pacing. In practice, modularity typically means the line can be expanded by adding stations, duplicating bottleneck processes, or reconfiguring tooling for updated product variants—an especially relevant capability in NEV supply chains, where product revisions can be frequent.

Automation-focused material flow and handling

E/E manufacturing often needs consistent handling to reduce defects (connector damage, misalignment, ESD risk, adhesive contamination). SIASUN’s described inclusion of a rotary warehouse suggests an approach that combines buffering (inventory smoothing) and controlled handling between processes.

Technology and Specifications

Case example: OBC production line metrics

In the published OBC automation line description, SIASUN states:

• 195 workstations across the production system

• 92% automation rate (as reported by SIASUN for the line)

These figures, if achieved in a customer deployment, imply a high proportion of operations are automated relative to manual interventions—often associated with higher consistency and easier standardization, provided the line is well maintained and robustly validated.

What an OBC is (and why it is manufacturing-critical)

An on-board charger (OBC) converts AC power (from a charging source) into DC power suitable for charging a vehicle battery—making it a central component in EV charging capability. Because OBCs interface with high-voltage systems and must meet automotive durability expectations, manufacturing commonly requires precise assembly, controlled adhesive/sealing processes, and rigorous functional testing.

Typical solution elements in E/E automation

While SIASUN’s public NEV E/E page centers on the OBC line example, E/E production automation in this category usually includes:

• Precision assembly and fastening (torque control, press-fit monitoring)

• Adhesive/glue dispensing and curing process control

• In-line inspection (vision checks for connectors, labels, orientation)

• Electrical safety/functional tests (continuity, insulation, basic functional verification)

• Traceability (station-by-station data capture, serialization, results logging)

SIASUN’s explicit mention of assembly, gluing, and test segments aligns with these standard E/E automation blocks.

Applications and Use Cases

Automotive electronics manufacturing (NEV supply chain)

The primary application is NEV component production—either at OEM plants or tier suppliers producing modules like OBCs. SIASUN’s example is directly positioned as an NEV E/E production automation solution via an OBC line.

High-volume, quality-sensitive production

E/E automation is most valuable when manufacturers need:

• Stable, repeatable output at scale

• Reduced rework and warranty exposure

• Auditable process data for customer and regulatory requirements

Multi-variant product environments

NEV components evolve rapidly (new power stages, new connector standards, new housing designs). Modular line strategies—like those highlighted by SIASUN—are commonly used to adapt production without replacing entire lines.

Advantages / Benefits

Consistency and quality control

Automation can reduce human variation in assembly and secondary processes. In E/E manufacturing, this often translates into improved repeatability for torque, dispense volume, alignment, and test coverage—especially important for modules exposed to vibration, temperature cycling, and high-voltage conditions.

Throughput and utilization

Large, coordinated lines can support higher throughput and more predictable output—particularly when buffer storage (e.g., rotary warehousing) is integrated to reduce stoppages and micro-downtime effects.

Data and traceability readiness

E/E production increasingly depends on digital traceability for audits, recalls, and process improvement. Integrated automation lines are typically designed to capture station-level outcomes and test results, improving root-cause analysis and compliance readiness.

Labor optimization

A high reported automation rate (such as SIASUN’s 92% figure for the OBC line example) implies reduced manual steps and potentially more consistent staffing needs—though final outcomes depend on maintenance, changeover frequency, and production stability.

FAQ Section

What is SIASUN New Energy Vehicle E-E Production Automation Solutions?

It is a set of factory automation solutions aimed at producing NEV electrical and electronic (E/E) components, with SIASUN publicly describing an example OBC production automation line that includes assembly, gluing, testing, and a rotary warehouse segment.

How does SIASUN’s E-E production automation work?

It works by integrating multiple automated process segments—such as assembly, gluing, and testing—into a coordinated production line, supported by structured material handling (e.g., rotary warehousing) to stabilize flow.

Why is E-E automation important for new energy vehicles?

NEV E/E components like the on-board charger (OBC) are safety- and reliability-critical. An OBC converts AC input into DC for charging the battery, and its manufacturing often requires controlled processes and strong test coverage to ensure consistent performance.

What are the benefits of SIASUN’s NEV E-E production automation?

Common benefits include higher process consistency, scalable throughput, and integrated testing/handling. In SIASUN’s published OBC line example, the company reports 195 workstations and a 92% automation rate, which—if matched in deployment—suggests extensive automation coverage.
