Application Case of Atonm Contactless Double Sheet Detector 8200S in Stamping Lines of a Suzhou Automotive Enterprise

Project Background

The customer is a leading enterprise in China's stamping automation sector, having undertaken a stamping production line project for a new vehicle model of an automotive enterprise in Jiangsu Province. The end client is a leading domestic new energy vehicle manufacturer, which has imposed stringent requirements on the processing precision of thin metal parts and equipment stability during the construction of the new production line. Given that double-sheet adhesion is prone to occur during high-speed material handling in the production line, a reliable double-sheet detection solution is required to address the issue of overlapping materials during loading, so as to ensure production continuity and yield rate.

The working conditions of the end production line are as follows:

Material: Iron

Thickness: 0.7-1.2mm

Production Line Speed: Cycle time of 6 spm

II. Solution

Core Equipment Selection

The Atonm MDSC-8200S Contactless Double Sheet Detector is adopted, with the deployment scheme as follows:

First Detection Point: Installed on the destacking end effector (the starting end of loading), it monitors in real time whether the metal sheets grabbed from the stack are overlapped.

Second Detection Point: Installed on the visual alignment table (positioning station before stamping) for secondary verification of the single-layer status of the sheet, ensuring no overlapping sheets enter the stamping process.

2. Solution Highlights

Dual Safeguard Mechanism: Dual-node detection at both the "destacking station and alignment table" completely eliminates the risk of missed detection caused by single-point detection failure.

High Adaptability:

Supports the detection of magnetic conductive metal sheets with a thickness range of 0.2-4mm.

Built-in storage for 200 sets of sheet material recipes, enabling quick switching of detection parameters for different specifications of metal sheets and adapting to multi-variety flexible production.

Intelligent Integration:

Supports multiple communication methods including Profinet, RS485 and terminal control, achieving seamless connection with the customer's PLC system to realize real-time alarm and production line interlock control.

A single device can connect 2 sensors, reducing hardware deployment costs.

3. Scenario Value

Damage Prevention: Prevents overlapped sheets from entering the stamping press and causing mold damage, reducing equipment maintenance costs.

Process Coordination: Works in synergy with the visual alignment system to improve stamping positioning accuracy and overall production efficiency.

III. Customer Benefits

Localization Replacement for Cost Reduction and Efficiency Improvement

Significant Equipment Cost Optimization: The new production line adopts Atonm MDSC-8200S, a domestic brand double-sheet detection solution, which drastically reduces procurement costs compared with imported equipment on the old production line. Meanwhile, it avoids supply chain risks caused by long-term reliance on imported equipment (such as long delivery cycles and difficulty in purchasing spare parts), achieving a cost-effective production line configuration.

Upgraded Local Service Response: Relying on Atonm's local technical team, the efficiency of equipment commissioning and maintenance has been significantly improved. The cycle from installation to mass production is much shorter than that of imported solutions, ensuring the rapid commissioning and stable operation of the new production line.

Performance Exceeding Expectations

Comprehensive Adaptation of Detection Capabilities: Targeting the characteristics of 0.7-1.2mm iron materials and 6spm high-speed cycle time, the dual-stage contact detection architecture (destacking end effector + optical alignment table) realizes dual precise verification of sheet material status. The detection accuracy and stability reach the same level as imported equipment, effectively avoiding mold damage and defective products caused by missed detection of double sheets.

Enhanced Flexible Production Capacity: The system supports quick switching of parameters for various specifications of sheet materials, easily meeting the frequent model change requirements of multi-model co-production in new energy vehicles, and significantly improving the production line's flexibility.

Supply Chain Security and Technological Independence

Elimination of Import Dependence Risks: It completely changes the old production line's reliance on imported double-sheet detection equipment, avoids the impact of international trade frictions or overseas supply chain fluctuations on production, enhances the independent controllability of core production line components, and provides a solid guarantee for the stable mass production of automobiles.

Independent Innovation in Industry Technology: The cooperation between the two parties breaks the traditional perception that "domestic detection equipment is insufficient in reliability", accumulates practical experience for subsequent domestic equipment to compete in high-end manufacturing fields, and helps China's automobile industry chain achieve independent breakthroughs in core component technologies.

Summary

By adopting Atonm MDSC-8200S, a domestic brand double-sheet detection solution, the automotive stamping production line has successfully optimized equipment costs, improved supply chain security, and achieved breakthroughs in technological independence while ensuring stamping quality and efficiency. This case verifies the mature application capability of domestic equipment in automotive-grade precision processing scenarios, and provides a replicable practical path for the independent and controllable development of new energy vehicle manufacturing.
