Referring to Fig. 1, embodiment of the present invention provides a kind of alignment film cure system, alignment film consolidates on substrate
Change, the substrate 50 is the substrate of the display with alignment film.The alignment film cure system includes setting several thimbles
11 plummer 10, clamping part 13, dark zone 15 and pre-baked area 17；The dark zone 15 is provided with the plummer 10 and first
Support platform 16.Set in the pre-baked area 17 and the second supporting table 21, described first are provided with a pre- oven 20, the pre- oven 20
The support supporting table 21 of platform 16 and second is air-flotation type support.The clamping part 13 is used for the substrate 50 that will be supported by several thimbles 11
Clamp and be moved to the top of first supporting table 16 and supported by air supporting, and for by the base in first supporting table 16
Supported in the second supporting table 21 that plate 50 is moved in pre- oven by air supporting.
Specifically, the alignment film on the substrate 50 has been set, it is necessary to which the alignment film cure system is solidified.
The alignment film cure system also includes manipulator, and substrate 50 is positioned on the plummer 10 by manipulator.Plummer
10 are provided with surface, and the telescopic surface relative to plummer 10 of several thimbles 11 is moved, such as several by cylinder scale
Thimble stretching or the surface of retraction plummer 10.Several thimbles 11 stretch out the surface and constitute a supporting plane with branch support group
Plate 50.The plummer 10 is realized with first supporting table 16 by travel mechanism changes position.Plummer 10 in figure with
The position of first supporting table 16 is schematic diagram, when substrate is changed to the first supporting table 16 from plummer 10, plummer 10 with
First supporting table 16 is changed position and can moved up and down or transverse shifting replacing.The plummer 10 with it is described
First supporting table 16 is respectively positioned in dark zone 15, and is linked with travel mechanism, such as slide rail or cylinder etc..
In the present embodiment, the surface of the supporting table 21 of the first supporting table 16 and second is equipped with several evenly distributed gas
Hole (not shown), for discharging gas with supporting substrate.Generally provided with the device for providing gas inside supporting table, if
Gas is vacuum gas, then provided for vacuum plant.Further, in second supporting table 21 supporting substrate 50 gas
Gas after namely being heated for hot gas, after substrate 50 enters in pre- oven 20, realizes back of the pneumatically supported gas to substrate
Heating, being conducted using heat can realize that the gas in the preheating to alignment film, and the second supporting table 21 out is uniform right
The substrate 50 is heated, and just can guarantee that the precuring stability of alignment film.
Further, the clamping part 13 is located at the top of substrate 50, including mobile support 131, is fixed on mobile branch
The adjutage 132 of frame 131 and the claw 133 located at adjutage 132.The mobile support 131 drives the movement of the claw of adjutage 132
Realize that claw 133 is moved to substrate.The mobile support 131 and claw 133 are symmetrical structure.The adjutage 133 can be with
It is that cylinder or the adjutage 132 are provided with cylinder, for stationary jaw and claw can be driven to lift.Will be described by manipulator
Substrate is positioned on claw, is carried by claw and is positioned substrate.Certain adjutage 132 and claw 133 can also be manipulator
Arm and hand.The mobile support 131 includes slide rail and pole, and the pole moves to drive adjutage to move on slide rail
It is dynamic, and then realize the movement of substrate.
It is fixed to be additionally provided with support frame of the alignment film cure system provided with the support clamping part 13, support frame as described above
The substrate accurately can be positioned over claw by the positioner of position claw, such as image measurer for auxiliary manipulator.
Referring to Fig. 1, in fact, on feed direction, the manipulator, dark zone 15 and pre-baked area 17 are set successively
Put, clamping part 13 is by the way that support frame is located at the top of dark zone 15 and can slide to pre-baked area 17.During work, two arrows in such as figure
Direction, manipulator is delivered to substrate 50 on the plummer 10 from feed direction, forms supporting surface to prop up while thimble 11 rises
Support group plate 50, makes base plate bottom be adapted to the support force of bottom by support, starts clamping part 13 and travel mechanism, travel mechanism afterwards
To change the supporting table 16 of plummer 10 and first, remove plummer 10, while the clamping substrate of claw 133 of clamping part 13 is relative
Side, mobile support 131 drives claw movement substrate is left plummer 10 and shifts to the first supporting table 16, the first supporting table 16
Immediately below substrate and substrate is floated by gas, after substrate is steady, substrate 50 is driven to pre- oven 20 by travel mechanism
Interior movement, substrate is floated by the gas after the heating of the second supporting table 21, realizes the precuring operation to the alignment film of substrate.
During this, now substrate is supported by thimble 11, then the pressure that can be downwards placed with buffer mechanism hand pass through top again
Clamping part 13 substrate clamping is had been converted to adapt to air-flotation type support in the first supporting table of air-flotation type 16, it is outer without top
Forcing can ensure that what substrate can be stablized supports, after substrate is stable, just can ensure that substrate Metacentre Height will
Substrate is moved to air-flotation type in the second supporting table 21 and supports and heat, this ensure that the stability of strutting system of substrate, and avoid
Because the thermal conductivity factor of thimble material is different from air, therefore in the curing process, alignment film and thimble contact area can be caused
Precuring effect in position has differences with non-contact area, causes uneven with liquid crystal display display brightness is formed as uneven
Phenomenon.The position relationship of the first supporting table 16 and the second supporting table 21 is schematic diagram in figure, the first supporting table 16 and second
Support platform 21 can be it is highly identical, can also be different, certain height same substrate is more firm.
Alignment film cure system described in the embodiment of the present invention first uses thimble-type plummer supporting substrate, is then replaced by
First supporting table of air-flotation type is supported in advance to substrate, is then entering the second supporting table branch in pre- oven by air-flotation type
Support carries out precuring, during this, uniform in basal plate heated, the uniformity of enhancing solidification film surface, uneven in the absence of thimble temperature
The problem of supporting, reduces uneven incidence.
Above disclosure is only preferred embodiment of present invention, can not limit the right model of the present invention with this certainly
Enclose, one of ordinary skill in the art will appreciate that all or part of flow of above-described embodiment is realized, and will according to right of the present invention
Made equivalent variations are sought, still falls within and invents covered scope.
