In 2020, affected by the epidemic, it will bring severe challenges to the Chinese tire industry, which is undergoing transformation and upgrading. Survival and development will become the main theme of the industry.


The tire industry is accelerating structural adjustments, and technological transformation has become the key to the industry. Consumers in the tire market are increasingly demanding tire performance improvements and enhancements. Tire companies have begun to increase their technical content and develop in the direction of new technologies such as smart, safe and comfortable tires. , This is also an inevitable way out.


In response to this challenge, IPG provides a new type of fiber laser cleaning technology that will help the automotive tire industry: improve quality, improve technology, increase production capacity, reduce costs, improve tire and body matching, and improve the overall performance of the vehicle.


Tire new technology and manufacturing, laser cleaning participate in the process of new technology.


New technology requirements for tires:


1. The noise reduction of tires tends to the comfort of silent tires.


2. Higher safety performance-the manufacturing process of anti-puncture and explosion-proof tire technology.


3. Auxiliary more advanced manufacturing process.


4. A more stable and high-speed online production line.


5. Higher integration.

For the technical requirements of the above new processes, the inner wall of the tire needs to be cleaned.


Cleaning needs to control the following key technical points:

For the technical requirements of the above new processes, the inner wall of the tire needs to be cleaned.


Cleaning needs to control the following key technical points:


1. The base material is not damaged—the manufacturer does quality control and evaluation.


2. Remove the oil on the inner surface of the tire. The main components of the oil are methylhydrosiloxane (5-15%) and water, with a cleanliness of 99.97%.


3. After cleaning, the friction coefficient of the inner surface will increase>35mN/m, and the surface tension will reach 38dyne/cm.


4. Considering production capacity requirements and increasing production capacity, reducing costs, the cleaning efficiency is more than 60cm/sec, and the most ideal is more than 90cm/sec.


5. Automated production line, uninterrupted and trouble-free operation.


6. IPG laser matching 2D galvanometer system can directly clean the range> 200mm, covering the X direction of the metal pressure-bearing layer, while meeting the large drop Y direction processing coverage of the curtain. (The following physical diagrams show two directions)




According to customer needs, a large spot with uniformly distributed flat top, high pulse energy, power above 300W, and large drop cleaning-need a large depth of field-large divergence angle laser to meet the technical development needs, corresponding to recommend IPG Of YLPN series products for application development.

Dyne pen


The dyne pen is used to test the surface tension of the material, and it can easily analyze the surface ability, hydrophilicity, wettability and other small changes of different solids. The analysis method is simple and effective. It only scratches a mark on the surface of the substrate, and the accurate result can be quickly known in 2-3 seconds. If there is no bead point, it means that the surface dyne is higher than or equal to the index marked on the surface tension test pen, and the effect is shown in the figure above. Otherwise, it does not meet the expected surface tension.

The cleaning is uniform, and the customer's assessment of the damage to the substrate far meets the requirements.


Removal cleanliness -99.99%, particle size reaches the micron level.


After cleaning, the adhesion force is above 38mN/m, and the surface tension reaches 38dyne/cm; the test meets the highest technical requirement of 46mN/m or above, and the surface tension reaches 46dyne/cm;


The cleaning efficiency meets the ideal design efficiency> 90cm? /Sec.


The instability of the laser's long-term operation is less than 3% (constant temperature for 8 hours of uninterrupted operation), which can realize and meet the online continuous operation.


The 2D system test covers a range of 330mm in the X direction, and achieves uniform cleaning of tires with a drop of 30mm in the Y direction.


Users can also use the Laser System software to conveniently operate, monitor, and diagnose the laser, and use real-time monitoring data to quickly diagnose and analyze the laser and the external control equipment connected to the laser; thereby greatly reducing the difficulty of system integration, debugging, and testing. Greatly reduce downtime, save manpower, and increase productivity.
