Automated Finished Tire Quality Control

Industry pain points and demands

In the final stages of tire manufacturing, ensuring the structural integrity and surface quality of vulcanized tires is a critical but difficult task. Traditional inspection processes often suffer from significant defect recognition delays, as human inspectors struggle to keep pace with high-volume production. This leads to low efficiency and a high dependency on manual re-inspection, which increases the risk of subjective error and missed defects such as bulges, cracks, or foreign matter.

 

Furthermore, manual inspection stations require extensive floor space and create a bottleneck that increases the overall cycle time (CT). Excessive workstation occupancy in the factory prevents a streamlined, "lean" manufacturing flow. Without a high-speed, automated system capable of capturing the complex geometry of a rotating tire, manufacturers face rising costs and the constant pressure of maintaining safety standards in a competitive global market.

SinceVision Solution: SRI7400R Integrated 3D Laser Profiler

01Comprehensive 360-Degree Online Inspection: By utilizing multi-camera networking during tire rotation, the SRI7400R performs full-surface acquisition of vulcanized tires. This ensures high-speed image acquisition that captures every angle, significantly reducing cycle time and cutting down on the manual re-inspection workload.
02Extreme Field of View for Large Components: Engineered for wide-area coverage, the SRI7400R features a massive Z-axis field of view of 339 mm at a 400 mm working distance. This allows for the reliable detection of defects across the entire tire profile, from the tread to the sidewall, in a single integrated setup.
03High-Speed Defect Identification: Operating at a scanning speed of 20 kHz with a 195 mm X-axis line width, the SRI series accurately identifies subtle defects that standard sensors miss. This precision allows manufacturers to select different models based on specific accuracy needs, ensuring optimal quality control and safety for every tire produced.
