Project Background:

Shenshan Automobile Industrial Park is one of the core new energy vehicle manufacturing bases in southern China, responsible for the high-capacity delivery of high-end vehicle models. This project focuses on the stamping workshop for car body panels, which is operated by a well-known domestic integratorOtto AutomationConstruction.The production line adopts a high configuration layout of "seven axis robot+eight workstations+automatic framing", with a designed production cycle of up to 13 SPM (times/minute)Strict requirements have been put forward for the stability and response speed of connected devices.

On site Configuration Checklist (Atorm Plan)

• Production line integrator: Otto Automation

Production cycle time: 13 SPM (Second Per Minute)

• Core process: unpacking ->transfer ->stamping ->automatic framing

Dual detection configuration:

Dismantling area (initial inspection): 1 unitMDSC-8200S dual detector(Contact/Magnetic)

Belt line (re inspection): 2 unitsMDSC-1500S dual detector(By equation)

1、 On site challenge: The 'fish that missed the net' under high-speed rhythm

At a beat of 13 SPM, it means that a feeding stamping picking cycle needs to be completed every 4.6 seconds. During the process of unpacking and belt transportation of sheet metal,Facing two major risks：

Vacuum grease adhesion: High strength steel is widely used in new energy vehicle panels, with a thick anti rust oil film on the surface, making it easy to lift up the second panel during disassembly and lifting.

• Transmission jitter: The high-speed grasping of the seven axis robot and the rapid start stop of the belt line can cause micro movements in the position of the sheet metal. If the sensor response is not fast enough or the probe installation is unstable, it is easy to generate false alarms and cause the entire line to stop.

2、 Hierarchical protection strategy: 8200S+1500S combination logic

In order to balance cost and efficiency while ensuring mold safety, the production line adopts a configuration strategy of "graded detection and multi-point interception".

1. First Line of Defense: Demolition Area (MDSC-8200S)

Deployment location: at the gripper of the robotic arm for disassembling stacks/at the magnetic separation position for disassembling stacks

Selection logic: Dismantling is the source of double sheet production. Selected hereMDSC-8200S (Contact type magnetic dual detector). As a mid to high end series of Atom, the 8200S has extremely high magnetic flux penetration, specifically designed for tightly adhered sheet metal.

• High stability: Contact measurement eliminates interference caused by air gap changes, ensuring that the judgment can be completed at the moment when the robotic arm picks up the sheet metal.

Magnetic specialization: For carbon steel parts of car bodies, using the principle of magnetic resistance change, it can accurately identify the small magnetic permeability differences between single and double sheets.

2. Second Line of Defense: Belt Line (MDSC-1500S x 2)

Deployment location: Belt conveyor station after unpacking/alignment platform before entering the press machine

Selection logic: Even if the stacking area filters out the risk of stacking, it is still necessary to prevent accidental stacking or foreign objects from falling during transportation. Two units are configured hereMDSC-1500S.

Dual channel redundancy: why use two? On the conveyor belt, the sheet metal is wider. Two sensors are used to detect the left and right sides or the head and tail of the sheet metal respectively, in order to prevent missed detection of "half adhesion" caused by local oil film adsorption on the sheet metal.

• High cost-effectiveness: As a pass through dual detector, the 1500S has stable performance and extremely fast response speed, making it very suitable as the "last goalkeeper" in relatively stable working conditions such as belt lines.

3、 Actual operational effect

Since its launch in Shenshan Automotive Industrial Park, this plan has been continuously operated in conjunction with the Otto seven axis robot production line

4、 Case Summary

The case study of Shenshan Automobile Industrial Park demonstrates a pragmatic and efficient approach to sensor application: 'A good horse is matched with a good saddle, but also a detailed account needs to be calculated'.

Use high-performance MDSC-8200S to intercept dual sheets at the source at the core risk point (unpacking); Build multi-point redundancy using the cost-effective MDSC-1500S in the transmission link (belt line). This combination of punches not only meets the strict safety standards of the 13 SPM high-speed line, but also effectively controls the overall electrical BOM cost of the project, which is worthy of reference for other automotive OEMs and integrators when planning new lines.
