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

Large engineering tires, primarily used in various construction scenarios, face harsh environments that demand high traction, passability, wear resistance, and puncture resistance. These tires are characterized by larger structural dimensions, multiple layers of fabric, cushioning layers, steel wires, as well as thicker and heavier bodies compared to standard small bias tires and radial tires. Their production processes significantly differ to meet performance requirements, featuring very wide and thick treads usually created with large winding equipment. During production, various factors may lead to issues such as insufficient adhesion, substandard thickness, or weight, necessitating inspection of the winding results to ensure compliance with process standards. Existing manual inspections cannot accurately measure or monitor key data like thickness, volume, or weight. Sectional measurement is time-consuming, wasteful, and inefficient, resulting in high inspection costs.


Solution

By utilizing 3D laser scanning technology, the layers of rubber on the tire are scanned both before and after the winding process to obtain the profile of the winding cross-section layer by layer. By analyzing changes in values at key points, key data such as the ratio of the cross-sectional areas on the left and right sides of the tread, longitudinal section, and volume are calculated. A comprehensive scoring system then evaluates whether the winding results meet process standards.

Measurement Details

Based on the initial scan's cross-section, key point locations are set for thickness measurements (such as center thickness, inflection point thickness, shoulder thickness, and sidewall thickness).

Key point positions dictate the setting of upper and lower limits, acceptance criteria, veto conditions, as well as parameters for volume, cross-sectional area, and weight.

Cross-Section Sampling MonitoringLongitudinal Section Integrated Analysis


Utilizing the created scoring template, subsequent tire wrappings are inspected online, with the system presenting information on 5000 cross-sections, summarizing longitudinal section data per cycle for intuitive analysis of the wrapping situation.

Scores are assigned to over 20 inspection items based on the scoring template, including specific key locations (like tire shoulders, sidewalls), inflection points, thickness, width, area, volume, etc., with a comprehensive score of these items serving as the evaluation standard.
