2022/09/23I. Background knowledge
The tire is one of the important parts of the automobile, it contacts with the road surface directly, and alleviates the impact suffered when the automobile is running together with the automobile suspension, so as to ensure that the automobile has good riding comfort and driving smoothness, ensure that the wheel and the road surface have good adhesion, and improve the traction, braking and trafficability of the automobile;Bearing the weight of the car, the role of tires on the car is crucial.
Tire manufacturing is a complex process, including many steps, and there are strict requirements for quality control in the whole manufacturing process.However, in the automatic production process of tires, it is inevitable that a small part of tires will have some defects, such as unqualified size, scratches, bulges, etc. In some processes, it is also necessary to detect the pattern of tires, DOT character recognition, etc. All of these require visual intervention.Nowadays, more and more automobile tire production lines are introducing visual inspection to check the quality of tires.
2. Application of LVM Line Laser Products in Tire Quality Inspection
1. Tire DOT code identification: The 3D sensor generates a height map by scanning the tire, which is used to identify the DOT code on the tire sidewall, and the character image can be clearly displayed.
Detection method
The LVM-2040 camera is fixed on the mobile platform and moves clockwise or counterclockwise along the tire for detection.
(Physical map of measurement)
Detection equipment
Test camera: LVM-2040
Scan line width: 111-234 mm
Sampling interval in Y direction: 0.05
Scanning mode: fixed camera and moving workpiece
Map collection effect
2. Detection of tread section size: The 3D sensor generates a height map by scanning the tire, which is used to measure the key dimensions of the tread, such as thickness profile, total width, shoulder width, middle width, shoulder thickness and middle thickness.
