The influence of COVID-19 brings sincere challenege to the upgrading of Chinese tire industry which is under difficult timmes.Existence and development will become the mainstream of the industry.Accelerating the structure adjustment and transforming techinique has become the key of this industry.Due to the higher and higher requirements from customer to the tire performance improvement , the tire industry has begun to improve the technology to new technology of smart, safe and comfortable, which is a must way. Under this situation, the IPG laser cleaning machine is helpful to the development of tire industry.It can improve the tire quality and technology, increase the production and lower the cost. Also it can upgrate the matching between the tire and car so that improving the whole performance.

The laser cleaning technology plays an important role in the new technology and manufacturing of tire industry, which includes the below requirements:

1.Noise reduction,trend of comfort of quiet tire

2.Higher safe performance-Anti-pin and explosion-proof tire technology

3.Assist more advanced manufacturing processes

4.More stable, higher-speed online production line

Aiming at the above requirements to the new technology, we need cleaning the inner wall of tire.

During the cleanng process, we need control the below key technology:

1. No damage to the substrate-Manufacturers do 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, and the cleanliness is 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, cleaning efficiency>60cm?/sec, the most ideal is>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. (Two directions in the following physical diagram)

Based on customer needs, a large spot with uniformly distributed flat top, large pulse energy, power above 300W, and large drop cleaning-need 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.

The comparison chart for cleaning with IPG YLPN－100－25*50*100－500-R laser is as follow:

Application result:

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

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

3: 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 more, and the surface tension reaches 46dyne/cm.

4: The cleaning efficiency meets the ideal design efficiency> 90cm?/sec.

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

6: The test coverage of the 2D system reaches 330mm in the X direction, achieving 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.
