Abstract: The tire building machine is a crucial equipment in the tire manufacturing process, and its
production performance directly affects the overall quality of the finished tires. As an important component
of the building machine, the laser marking device can effectively enhance the precision and efficiency of
the building machine during production. This article introduces the debugging principle and application of
the laser marking device for tire building machines, elaborates on the steps and considerations for laser lamp
calibration and debugging, and verifies its effectiveness through case analysis, providing a reference for
improving the tire building process.

The building quality of tires is crucial to their visually observe whether the laser line projection positions
performance. To ensure the building accuracy of tires, the laser at 1200 mm and 1500 mm are accurate. The laser marking
marking device of the building machine plays a vital role. device needs to be used in conjunction with the building drum
Through precise beam projection, the laser marking device of the building machine. According to the requirements of
can help operators accurately align the position of the rubber the building process, the operating direction of the internal
compound, thereby improving the alignment accuracy and laser light needs to be parallel to the axis of the building drum
process stability during the building process. This article will to ensure accurate precision. However, in actual debugging,
explore the calibration and debugging methods of the marking there is no good method to ensure the parallelism between the
device. operating direction of the internal laser light and the axis direction
With the diversification of market demand for tires, more of the building drum. Regarding the debugging process, due to the
functional requirements have been put forward for the laser distortion and stretching of the coordinate paper caused by long-
marking device guiding tire building. However, the previous term use, it is necessary to re-paste the coordinate paper and adjust
assembly and debugging methods have been difficult to meet the reference position at regular intervals, leading to issues such as
the new equipment demands, resulting in many problems inconsistent accuracy of the calibrated marking device.
during the production debugging process. For example, To address the aforementioned issues, we analyzed the
according to the requirements of the tire building machine, it is working principle of the laser marker, produced specialized
necessary to ensure the accuracy of the laser projection position debugging tooling, and formulated more efficient and
of the laser marking device within the range of 1200~1500
mm. However, in the actual calibration process, due to the Biography: Yang Duo (1995-), male, holds a bachelor's degree
large calibration range, there is no suitable mechanism for and works as a research and development engineer as well as a junior
mechanical engineer. He is primarily engaged in the structural design and
this task, and it often relies on pasting coordinate paper on
optimization management of laser light markers used in conjunction with
walls or floors for calibration. However, this method cannot tire building machines.
