- the difference is that the friction rollers arranged side by side in FIG. 7 and FIG. 8 are replaced with a plurality of friction rollers spaced apart around the central rotation axis in the embodiment.
- the friction roller is raised or lowered by the lifting mechanism.
- the lifting and lowering of the friction roller in the embodiment can be realized by any one or a combination of the lifting and lowering of the lifting mechanism or the rotation of the central rotating shaft, and the setting is beneficial to increase the rising and falling of the friction roller.
- the friction roller can be controlled by another control mode to perform the friction orientation, thereby prolonging the service life of the device and facilitating maintenance and replacement.
- Other structural configurations and method processes in this embodiment are similar to the previous embodiments, and are not described herein again.
- the friction orientation device and the system provided by the embodiments of the present invention can perform the rubbing orientation on the mother board, thereby completing the rubbing orientation of the plurality of different substrates, thereby avoiding the display failure caused by the unevenness of the alignment film caused by the conventional rubbing process.
- the continuous rise and fall of the friction member is realized in the movement of the machine, and the machine does not need to stop, which not only avoids the waste of time caused when the machine is stopped, but also can effectively improve the precision of the reduction of the friction roller.
- the friction member including a plurality of friction rollers can realize the rubbing orientation of a plurality of different substrates, thereby solving the technical problem that only the single substrate can be rubbed and oriented in the prior art.
- the coordinate information of different substrates on the motherboard is used to control the rise and fall of the friction components, thereby eliminating the manual operation or other components for collecting the shape and position information of the substrate, so that the friction orientation device has a simple structure, reduces costs, and improves product market competitiveness. .
- Yet another embodiment of the present invention provides a display substrate prepared by using the rubbing orienting device of any of the above embodiments of the present invention.
- Still another embodiment of the present invention provides a display device including the display substrate described in the foregoing embodiments.
