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

Tire sidewalls are marked with various raised or indented tire specifications, detailing the type and performance of the tire. These marks, along with the tread pattern, reflect the brand's image and characteristics to some extent. Sidewall information is created during the vulcanization process, where operators change molds or segments based on tire models to form the necessary vulcanization mold. This process can lead to human errors or wear of the segments, causing mismatches with the standard and quality issues in tire production. Therefore, inspecting the first tire's characters after vulcanization can verify mold accuracy, preventing significant production losses due to incorrect information in an entire batch. Currently, this inspection is mainly performed manually, which is time-consuming, lacks precision, and is prone to omissions.


Due to the three-dimensional nature of sidewall characters, 3D inspection can build upon 2D detection to extract three-dimensional information of the characters, making precise recognition of sidewall characters possible. Thus, applying 3D machine vision to the inspection of initial tire characters, by scanning the sidewall with a 3D laser sensor and employing image processing algorithms to extract character information, followed by comparing this information with standard templates using character recognition algorithms, can verify whether there are errors, omissions, unauthorized additions, or wear and tear in the sidewall text and patterns.
