Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.It should be appreciated that detailed description of the invention described herein is merely to illustrate and explains the present invention, it is not limited to the present invention.
The present invention provides a kind of rubbing device, as shown in Figure 1, this rubbing device includes friction roller 101 and friction base station 102, friction base station 102 treats rubbed substrate 103 for carrying, friction roller 101 is provided with friction cloth, friction roller 101 is arranged on above friction base station 102, rub for treating rubbed substrate 103, described rubbing device can also include pre-rubbed substrate 104, can there is relative movement along the surface of pre-rubbed substrate 104 and pre-rubbed substrate 104 in friction roller 101, pre-rubbed substrate 104 can move towards or away from friction base station 102.The position that relative movement between friction roller 101 and pre-rubbed substrate 104 can be friction roller 101 is fixed, and pre-rubbed substrate 104 moves；Can also fixing for the position of pre-rubbed substrate 104, friction roller 101 moves, as long as friction roller 101 can be made at the surface scrolls of pre-rubbed substrate, thus rubbing in advance on the surface of pre-rubbed substrate 104.
In the present invention, when friction roller 101 treat rubbed substrate 103 rub time, pre-rubbed substrate 104 may be located remotely from friction base station 102；When friction roller 101 rubs the regular hour and needs the friction cloth of friction roller 101 is rubbed in advance, pre-rubbed substrate 104 can near friction base station 102 so that friction cloth rubs in advance on the surface of pre-rubbed substrate 104.Compared with prior art, it is not necessary to pre-rubbed substrate 104 being moved to friction base station 102, thus the allocating time of pre-rubbed substrate 104 can be reduced, thus reducing the time of pre-friction process, improving production efficiency；On the other hand, repeatedly pre-friction can carry out on same pre-rubbed substrate, thus can reduce the replacement frequency of pre-rubbed substrate, thus improving production efficiency and alleviating the workload of operator.
Generally, pre-rubbed substrate 104 can be normal white glass or ito glass, it is also possible to for the substrate that other macromolecular materials are made；Treat that rubbed substrate 103 has the substrate of polyimides (PI) film for surface configuration.
Setting for the ease of pre-rubbed substrate 104, further, as shown in Figure 1, described rubbing device can also include friction load carrier 200 in advance, pre-friction load carrier 200 is used for carrying pre-rubbed substrate 104, and pre-friction load carrier 200 can drive pre-rubbed substrate 104 to move towards or away from friction base station 102.
Further, for the ease of the movement of the load carrier 200 that rubs in advance, as in figure 2 it is shown, described rubbing device can also include guide rail 300, pre-friction load carrier 200 is arranged on guide rail 300, and pre-friction load carrier 200 slides along guide rail 300.
The pre-move mode rubbing load carrier 200 is not specifically limited by the present invention, as long as can move along guide rail 300 towards or away from friction base station 102.The movement of the pre-load carrier 200 that rubs can manual operation, it is also possible to automatically carry out.In order to improve work efficiency, described rubbing device can also include the driving device (not shown) electrically connected with the load carrier 200 that rubs in advance, and pre-friction load carrier 200 can slide along guide rail 300 in the driving of described driving device.
nullSo that the pre-friction that carries out on pre-rubbed substrate 104 surface of friction roller 101 with treating that the friction that rubbed substrate 103 surface carries out is independent of each other，Further，As shown in Figure 1，Pre-rubbed substrate 104 can move between the first predeterminated position P1 and the second predeterminated position P2，Distance between first predeterminated position P1 and friction base station 102 is less than the distance between the second predeterminated position P2 and friction base station 102，When pre-rubbed substrate 104 is positioned at the first predeterminated position P1，The friction cloth of friction roller 101 can contact with pre-rubbed substrate 104，Thus rubbing in advance on the surface of pre-rubbed substrate 104，Now，Can will treat that rubbed substrate 103 takes off from friction base station，To prevent the friction roller 101 being not fully complete pre-friction from affecting friction effect with treating rubbed substrate 103 to contact；When pre-rubbed substrate 104 is positioned at the second predeterminated position P2, friction roller 101 can be treated rubbed substrate 103 along the surface treating rubbed substrate 103 and rub, now, pre-rubbed substrate 104 does not contact with friction roller 101, thus prevent pre-rubbed substrate 104 friction roller 101 treat contact with the friction cloth of friction roller 101 when rubbed substrate 103 rubs and affect the fine hair of friction cloth towards.
It is understood that as it is shown on figure 3, pre-rubbed substrate 104 can also move to the distance between the 3rd predeterminated position P3, the 3rd predeterminated position P3 and friction base station 102 more than the distance between the second predeterminated position P2 and friction base station 102.When described rubbing device quits work, pre-rubbed substrate 104 can move to the 3rd predeterminated position P3, in order to carries out replacing or other plant maintenances work of pre-rubbed substrate 104.
