Description

Technical Field

[0001] The utility model relates to the technical field of tire marking, in particular to a tire laser marking machine. Background Art

[0002] In the current rubber tire manufacturing industry, the widely used laser marking technology provides an efficient means for tire identification and traceability.

[0003] In the early stage, the laser marking of rubber tires mainly relied on manually operated handheld laser marking machines. Although these devices are flexible, they are unable to cope when faced with the complex and variable trademark patterns on tires, especially those with delicate designs and long lengths. The limitation of handheld laser marking is that it is difficult to ensure continuous and accurate coverage of the entire trademark area in one operation. Often, the operator needs to frequently adjust the device position, refocus, or even repeat the marking multiple times. This not only greatly increases the labor intensity but also severely restricts the production efficiency. More critically, due to the intervention of human factors, the consistency of the marking results cannot be guaranteed, and problems such as content misalignment, uneven spacing, and inconsistent clarity often occur, affecting the aesthetics and market acceptance of the product.

[0004] Therefore, in the prior art, there have emerged automatic marking machines that can automatically mark the outer side of tires. These machines can automatically identify the tire size, shape, and preset marking positions, and can complete the precise marking of complex patterns in one go without manual intervention. This not only greatly improves the work efficiency but also improves the marking quality. However, the existing tire marking machines have complex structures, high equipment costs and maintenance costs, low economy and popularity, and are not suitable for small enterprises. Summary of the Utility Model

According to the outer diameter of the tire and the required marking position, the laser marking controller controls the radial moving mechanism 2 and the vertical moving mechanism 5, so that the radial moving mechanism 2 drives the laser 1 to move above the marking position, and the vertical moving mechanism 5 drives the laser 1 to move to a suitable marking height. Then manually rotate the support table 9, and the second rotating member 8 rotates relative to the base 7, driving the tire to rotate to the starting position of marking. Finally, according to the content information to be marked, the laser marking controller automatically calculates multiple marking position points, drives the laser 1 to rotate through the rotary driving mechanism 4, and cycles through the steps of marking and rotating until the marking is completed.

[0042] The radial moving mechanism 2 and the vertical moving mechanism 5 in this embodiment are both linear moving mechanisms in the prior art, such as linear motors, gear racks, telescopic cylinders (hydraulic cylinders or pneumatic cylinders), or ball screw motors, etc. The rotary driving mechanism 4 in this embodiment is a rotary motor in the prior art, and the transmission method between the rotary motor and the first rotating shaft can be a coupling, belt drive, sprocket chain drive, or gear drive, etc.
