As shown in Figure 2, be a kind of friction orientation device 100 disclosed in this enforcement, comprise the worktable 15 and friction running roller 12 that are oppositely arranged; At least one is positioned at friction running roller 12 and repairs platform 13 away from the friction cloth of described worktable side; Wherein, friction running roller 12 surface is provided with friction cloth 11, and friction cloth 11 is for having the macromolecular material of SME.
Shown in concrete reference diagram 2, when this friction orientation device 100 works, worktable 15 also comprises contact with friction cloth 11 treat orientation substrate 16, certainly, friction cloth 11 is also repaired platform 13 with friction cloth and is contacted.Wherein, the Main Function that friction cloth repairs platform 13 is exactly: when the part that friction cloth 11 contacts with orientation substrate 16 carries out friction orientation to orientation substrate 16, meanwhile, with another part friction cloth 11 repaired platform 13 with friction cloth and contact, repair platform 13 by friction cloth and repair.Namely realize when friction cloth 11 while treat while orientation substrate 16 carries out orientation process, repair while repair platform 13 pairs of friction cloth 11 by friction cloth, thus defects such as repairing friction cloth 11 cloth hair deformation that orientation process process causes can be solved in time, extend the friction cloth life-span.
To the process that friction cloth 11 is repaired be elaborated below:
For friction cloth 11, it has the macromolecular material of SME.Wherein, when SME refers to that such macromolecular material is once-forming, some characteristics of original state can be remembered, arbitrary deformation can be there is after the sizing of such macromolecular material, under the effect of lower temperature or external condition, the deformation of generation is fixed up, when the stimulation of the specific external temperature of the macromolecular material giving to have deformed or light/electricity/magnetic, such macromolecular material can Quick-return to original state.
In the utility model, the friction cloth that friction cloth replaces the memory-less effect that existing apparatus uses is done by adopting the macromolecular material of SME, recover principle corresponding friction cloth of arranging in pairs or groups by different shape memories and repair platform, the friction cloth of thermic induction type shape memory repaired by the reparation platform having heating function as adopted.
Wherein, friction cloth can have for a kind of material in Thermally stimulated shape memory polymer material, photic induction type shape memory high molecule material, electroluminescent induction type shape memory high molecule material or mangneto induction type shape memory high molecule material.Correspondingly, friction cloth reparation platform is repaired by heating, optical radiation or the friction cloth of electromagnetic mode to dissimilar SME.
At the utility model, in one preferably embodiment, friction cloth can have for Thermally stimulated shape memory polymer material, the polyurethane of such as SME.
Wherein, the ultimate principle of the SME of Thermally stimulated shape memory polymer material is: thermoinduction type shape memory high molecule material has two phase structure, namely by keeping the Stationary liquid of shape and the reversible phase composition of reversible change can occurring along with variation of ambient temperature, wherein the reacting condition of reversible relative ambient temperature is responsive.The Stationary liquid of shape memory high molecule material has relatively high glass transition temperature (Tg) or crystalline melt temperature (Tm); And the structure of lower Tg or Tm can be had by anti-phase.When ambient temperature is higher than reversible phase transition temperature (Ttrans), the molecule of anti-phase can will be in elastic state, can deformation be there is by under External Force Acting, and now because Stationary liquid has higher Tg or Tm, therefore still be in glassy state or crystalline state.When temperature is lower than Ttrans, be reversiblely in frozen state mutually, after external force is removed, can the deformation of anti-phase be just fixed.When ambient temperature is elevated to Ttrans again, shape memory high molecule material due to its can anti-phase elasticity recover and restPose.So far, complete the circulation of " remembered primary state → fixed deformation state → recovered primary state ", this circulation can be carried out repeatedly repeatedly.
When friction cloth adopts polyurethane (SMPU) of thermic induction type SME, then need to carry the friction cloth with heating function and repair platform.When friction cloth 11 is at the tiling shape of original state or drum, the cloth hair in friction cloth 11 is in the arrangement of rule; Such as, but in transportation, then deformation can occur, fold diminishes, or in orientation process technological process, there is the deformation of cloth hair, so make orientation process poor effect, can not play and the anchorage of liquid crystal molecule is acted on.So need to repair platform 13 to friction cloth 11 by friction cloth to revise accordingly, make it return to original shape.
Continue with reference to shown in figure 2, the friction cloth reparation platform 13 with heating function specifically can comprise at least one ion blower with heating function (not shown in Fig. 2), due in order to friction cloth 11 is carried out heating repair, then the heating temperature range of this ion blower is 40 DEG C-60 DEG C, the friction cloth of thermic induction type SME can at this temperature section, and comparatively good returns to initial configuration.Certainly, repair on platform 13 can be furnished with multiple ion blower in whole face in friction cloth, also according to actual repair needs, the layout of multiple spot can be carried out.Moreover, if orientation process process requires high especially to the reparation of friction cloth, also can repair friction cloth by arranging multiple friction cloth reparation platform, wherein, friction cloth repairs the top that platform not only can be positioned at friction running roller, can also be positioned at the both sides of friction running roller.
What adopt due to the friction cloth in friction orientation device is the friction cloth with SME, thus saves traditional friction cloth and need aging (aging) time before the use.Simultaneously, both can repair the fold produced in friction cloth transportation to diminish, also the distortion produced in orientation process (rubbing) processing procedure can synchronously be repaired, reduce in rubbing processing procedure relevant to friction cloth bad, improve the quality of orientation process technique, extend friction cloth serviceable life, cost-saving.
Continue with reference to figure 2, friction cloth reparation platform 13 is fixed as by the first stationary installation 14 with friction running roller 12 and is oppositely arranged.Wherein, first stationary installation 14 comprises the first fixed head 14a and is arranged at the first stationary shaft 14b between described first fixed head and described worktable, wherein the first fixed head 14a and the first stationary shaft 14b can be integrative-structure, be mutually permanently connected, also can be split type setting, both be each other for being flexibly connected.Concrete connected mode, does not do any restriction at this.In addition, the first stationary shaft 14b at the lower position of the first fixed head 14a, closer to worktable 15.
In addition, friction running roller 12 to be arranged on the first stationary shaft 14b and with described first stationary shaft for axis rotates, when friction orientation device 100 works, friction running roller 12 axle centered by the first stationary shaft 14b carries out clockwise or counterclockwise rotation, in general, the profile of friction running roller 12 is cylindrical roller shape.Friction cloth is repaired platform 13 and is fixed on the side of the first fixed head 14a near friction running roller 12, and wherein friction cloth reparation platform 13 can be fixedly connected with the first fixed head 14a by modes such as bolts.Certainly, friction cloth repair platform 13 be also can with between the first fixed head 14a for being flexibly connected, namely friction cloth reparation platform 13 be demountable structure.In other words, friction cloth can be repaired platform 13 and disassemble from friction orientation device 100, as independently parts, friction cloth be repaired.
Continue with reference to shown in figure 2, because friction running roller 12 repairs platform 13 in friction cloth and treats between orientation substrate 16, so, when friction orientation device 100 works, be attached to friction running roller 12 outside friction cloth 11 can not only with treat that orientation substrate 16 contacts, orientation action is carried out to it; And friction cloth 11 is also repaired platform 13 with friction cloth and contacted, repair platform 13 pairs of friction cloth 11 by friction cloth and repair, namely achieve and carry out orientation action and carry out repair.
