SIASUN SA7A-7/0.50 SCARA Robot 4 Axis Robotic Arm for Industrial Purpose for Medium-Payload Precision Pick and Place

The SIASUN SA7A-7/0.50 is a high-precision scara robot 4 axis system engineered for reliable robotic arm for industrial purpose applications, featuring a 7 kg payload capacity and a 500 mm reach. This unit is specifically designed for medium-payload precision pick and place tasks in environments such as 3C electronics assembly, lithium battery production, and automotive component manufacturing. By utilizing a modular design and proprietary core components, it minimizes mechanical vibration and maintenance requirements compared to legacy horizontal multi-jointed robots.

Product Type & Category Positioning

The SIASUN SA7A-7/0.50 belongs to the industrial SCARA (Selective Compliance Assembly Robot Arm) category, specifically positioned as a medium-payload, high-speed solution. These robots are defined by their horizontal joint configuration, which ensures high compliance in the X-Y plane while maintaining exceptional vertical rigidity for Z-axis assembly and material handling. Building on this classification, this model serves as a core component for automated production lines that require consistent, high-speed cycle times and repeatability. It is categorized within the SA7A series, which bridges the gap between compact 4 kg units and heavy-duty 20 kg variants.

Technical Highlights

The SA7A-7/0.50 incorporates a dual-support structure that significantly enhances structural rigidity during high-speed operation. This design minimizes the vibrations typically associated with rapid acceleration and deceleration, ensuring the end-effector reaches target coordinates with maximum precision.

Additionally, the modular architecture of the SA7A platform simplifies integration and reduces long-term maintenance costs. The internal wiring design eliminates the need for bulky external corrugated tubes, which reduces spatial constraints and prevents cable fatigue in tight industrial cells.

Application Scenarios

3C Electronics Assembly: Executes high-speed placement of small components with repeatability up to ±0.03 mm, increasing throughput by approximately 15-20% in standard testing. Lithium Battery Manufacturing: Facilitates the handling and stacking of battery cells, ensuring consistent positioning for welding or assembly stages while maintaining structural stability. Small Component Packaging: Optimized for pick-and-place tasks where a 7 kg payload and 500 mm reach provide the necessary balance between speed and coverage for automated boxing or sorting lines.

Selection Recommendations

Suitable: High-volume electronic assembly lines requiring cycle times ≤0.8s and consistent repeatability of ±0.03 mm within a 500 mm radius. Not Suitable: Heavy-duty metal casting or large-scale automotive chassis welding, where payload requirements exceed the 7 kg rating and shock loads could damage the internal gearboxes. Comparative Reference: For applications requiring a larger workspace, consider the SIASUN SA7A-7/0.60 or the SA7A-7/0.70, which provide identical payload capacities but offer extended reach (600 mm and 700 mm, respectively) to accommodate larger assembly cells.

FAQ

1. What are the lead time and availability for the SIASUN SA7A-7/0.50?

We typically process orders within 10 to 15 working days, provided the unit is in stock at our regional distribution center. For bulk orders exceeding 5 units, we provide a customized shipping schedule based on production capacity. Our team at Beijing Zhongping Technology coordinates with international logistics partners to ensure door-to-door delivery. Please contact us to confirm current inventory status before placing your formal purchase order.

2. Does this robotic arm require specific maintenance schedules?

Routine maintenance is minimal due to the industrial-grade sealed joints and proprietary gearboxes integrated into the SA7A series. We recommend a basic visual inspection every 500 operating hours and a lubricant check every 2,000 hours of use. Our technical team provides a comprehensive maintenance manual with every unit. If you need a certified technician to perform onsite services, we can arrange this for an additional fee.

3. How does the accuracy of this model compare to other SA series units?

The SA7A-7/0.50 offers a high repeat positioning accuracy of ±0.03 mm, consistent with the rest of the SA7A series. This precision is maintained through the proprietary control system and dual-support mechanical structure. While the accuracy remains stable across the series, your choice should be based primarily on the required payload and reach for your specific workspace. Contact us for technical comparisons if you are debating between this model and the 10 kg payload variants.

4. What is the total cost, and what currency do you accept?

Pricing typically ranges from $12,000 to $22,000 USD depending on specific configurations, software options, and shipping requirements. Prices fluctuate due to exchange rates, tariffs, and factory adjustments. For an accurate quotation, contact Beijing Zhongping Technology directly. We accept bank wire transfers as the primary payment method for international industrial equipment procurement.

5. Are there software licenses required for operation?

The unit comes equipped with a proprietary SIASUN control system that includes basic operational software. You do not need to pay recurring subscription fees for standard robotic arm movement and pick-and-place functionality. However, if you require advanced simulation tools or specialized API integration for your production line, these modules are available for an additional fee.

6. Is technical support available for installation and integration?

We provide comprehensive documentation, including detailed CAD files and installation guides, to assist your engineering team. For complex integrations involving multiple robots or custom end-effectors, we offer remote video support sessions. If onsite commissioning is necessary, our technical department can dispatch a specialist to your facility for an additional fee.

7. What is the warranty policy for this industrial robot?

Each unit includes a standard 12-month manufacturer warranty covering defects in material and workmanship. This warranty period begins upon the successful delivery of the equipment to your facility. If you encounter any functional issues, please provide the serial number to our support team for an initial remote diagnostic. We facilitate repairs or part replacements under our internal quality assurance guidelines.

8. Can this robot handle heavy-duty machine tending tasks?

While this model is designed for a 7 kg payload, it is best suited for light-to-medium pick and place tasks. If your application involves heavy machine tending or high-impact loading, we recommend the SA20A-20/0.80 series. The SA20A series features a reinforced actuator system specifically engineered for the torque demands of heavy industrial machine tending.

9. How do we request a formal quote for procurement?

Submit your request by providing the exact model number, the quantity required, and your destination shipping address. Our sales department will generate a proforma invoice including estimated lead times and freight costs. We ensure all documentation is ready for your local customs clearance process upon shipment.

10. Do you provide training for operators and maintenance staff?

We offer virtual training modules that cover system setup, programming basics, and safety protocols for your staff. These modules are designed to ensure your operators can manage routine tasks independently. For hands-on, intensive training programs at your site or our facility, we can provide customized packages for an additional fee.
