Rubber& Tire

Tires are the only parts of a vehicle that come into contact with the ground, affecting the vehicle's handling, comfort, and safety. OiSmart has deeply cultivated the tire manufacturing field, integrating 3D vision inspection technology closely with tire production processes. Specifically designed for various tire production stages such as extrusion, bead wire, cutting, molding, and vulcanization, they have independently developed a series of vision inspection solutions. With a profound understanding of tire production processes, customer focal points, and years of onsite project experience, OiSmart has developed a series of standard equipment using their proprietary 3D sensors and 3D vision software platform as the core. This equipment can be rapidly deployed and used by companies, while also offering highly flexible customized solutions based on the company's budget and production realities. This comprehensively meets various tire inspection needs, helping tire manufacturing enterprises reduce production costs, enhance automation levels, and optimize quality management.

Industry Challenges and Needs

In the tire production process, many stages involve stitching and adhering rubber materials to form splices, such as the splicing of steel belts and fabrics in the cutting stage and the formation of joints from steel belts, fabrics, treads, and pre-composite materials in the molding stage. Defects in these splices, such as gaps, misalignments, or breaks exceeding process standards, can directly affect product quality and significantly reduce tire lifespan.Some tire manufacturers use visual inspections by technical staff as part of their quality control process. This method has several limitations, including subjectivity, inconsistency, high labor input and intensity, time-consuming inspections, and limited data collection, often requiring production to be halted, resulting in extremely low efficiency. Manual inspections also increase the risk of missed defects, potentially allowing substandard products to proceed to subsequent stages, leading to severe quality issues.


Utilizing 3D laser technology, this method captures the 3D point cloud data of rubber materials through 3D scanning. It then assesses for abnormalities such as over/less, dog-ear, off-center issues, and width by calculating key metrics, enabling automatic inspection of the quality of rubber joints and real-time monitoring of production standards.

Measurement Details

Measurement capabilities include detecting over (where joint values are >0), Less(where joint values are<0), Dog-ears ( where edges are offset), off-center (inconsistent widths on either side), and overall width discrepancies. It can also identify missing material (No Material) and incorrect material (Material Error) defects.

Inspection Principle

Joint Detection involves identifying the starting line (collection of red points) and the endpoint line (collection of green points). The joint measurement is calculated by subtracting the distance of the starting mapped point (red point) from the endpoint point (green point), where a positive value indicates overlap, and a negative value indicates a gap. The detection of material staggering is determined by comparing the horizontal coordinates of the material edge points (blue points) to calculate the staggering value.
