This locking piece 760 has internal thread connecting hole 761 at one end.This internal thread connecting hole 761 is suitable for the external thread coupling part 420 of piston 400.Locking piece 760 has projection 762 at one end.After the external thread coupling part 420 with piston 400 was inserted in the internal thread connecting hole 761, projection 762 prevented external thread coupling part 420 sliding leaning against on the inside surface of locking piece 760.
Have given external diameter and given length for second 770.This second 770 has coupling part, bottom 771 at one end.This second 770 perpendicular positioning.
Second 770 coupling part, bottom 771 levels are connected to the external thread coupling part 420 of piston 400, and from external thread coupling part 420 horizontal separation of piston 400.The external thread coupling part of this second 770 coupling part, bottom 771 and piston 400 can be multiple shape.
The bar of this second 770 and actuator 720 utilizes connection unit C3 so that second 770 mode that can rotate is connected to each other.
The operation of second embodiment of rotary drive unit 700 is described now.
At first, this actuator 720 moves down second 770, so that the internal thread connecting hole 761 on the locking piece 760 can be passed in second 770 coupling part, bottom 771.
The external thread coupling part 420 that is connected to the piston 400 of cylinder component 300 is connected to second 770 coupling part, bottom 771 by operating personnel.Move second 770 on the actuator 720.So, the external thread coupling part 420 of piston 400 is inserted in the internal thread connecting hole 761 of locking piece 760, and closely contact with it.
790 work of second rotation motor.The rotary power that second rotation motor 790 produces passes to second 770 that is connected to follower gear 781 by driven wheel 782 and follower gear 781.Accept this second 770 piston 400 that is rotatably coupled to second 770 of rotary power.
Supporting shell 230 is provided with the linear drive unit that moves up and down rotary drive unit 700.
As example, this linear drive unit 800 comprises the rear side that is fixedly connected to the base component 710 of forming rotary drive unit 700, by the outstanding moving member 810 in the hole on the backboard 232 231, be arranged on first static element 820 on this backboard 232, be arranged on second static element 830 on the bottom of this backboard 232, be installed in the 3rd rotation motor 840 on first static element 820, thereby and be connected to moving member 810 and second static element 830, ball-screw that the rotary power rotation that produces by the 3rd rotation motor 840 moves up and down this moving member 810.
This moving member 810 has given area and given thickness.This moving member 810 has threaded hole.
This ball-screw 850 passes the threaded hole on the moving member 810.One end of this ball-screw 850 is connected to the motor drive shaft of the 3rd rotation motor 840, and the other end of this ball-screw 850 is rotatably connected to second static element 830.
The operation of linear drive unit 800 is described now.
840 work of the 3rd rotation motor.The rotary power that the 3rd rotation motor 840 is produced passes to ball-screw 850, thereby rotates this ball-screw 850.The rotation of this ball-screw 850 makes moving member 810 move along straight line.
When the rotation of the 3rd rotation motor 840, on move moving member 810.When 840 reverse rotations of the 3rd rotation motor, move down moving member 810.
Moving member 810 makes base component 710 and comprise that the rotary drive unit 700 of this base component 710 can move.This rotary drive unit 700 can move the piston 400 that is connected to rotary drive unit 700 along straight line.
Operation according to LC coating machine described in the utility model is as follows.
Motherboard is installed on the saddle 110.First driver element 140 and 150 work of second driver element, thus coating head device moved according to the input data along X-axis and/or Y direction.
When X-axis or Y direction move coating head device, piston 400 glides in cylinder and gives set a distance, to discharge a dropping liquid crystalline substance by nozzle unit 600 on the given area on the motherboard.Just, each piston glides to set a distance, just a dropping liquid crystalline substance is discharged on the given area on the motherboard by nozzle unit.
The coating operation of LC coating machine is described in further detail.
As shown in Figure 13, rotary drive unit 700 rotary-pistons 400, so that the flow channel 322 that the groove on the piston 400 430 is faced in the cylinder 320, cylinder component 300 has the piston 400 that is installed on the rotary drive unit 700 simultaneously.In case the groove surface on the piston 400 is to flow channel 322, rotary drive unit 700 just quits work.
In case the sliding set a distance of giving on the piston 400, linear drive unit 800 just quits work.Then, rotary drive unit 700 rotary-pistons 400 are so that the groove on the piston 400 430 is in the face of flow pass 323.In case the groove 430 on the piston 400 is in the face of flow channel 323, rotary drive unit 700 just quits work.
These linear drive unit 800 work are to move down rotary drive unit 700 to set a distance.Each piston glides to set a distance, just dropping liquid crystalline substance is discharged on the given area on the motherboard by flow pass 323 and nozzle unit.
The process of discharging liquid crystal by nozzle unit 600 is same as described above.
For example, if ten (10) dropping liquid crystalline substances will be discharged on each panel area that marks on the motherboard, the amount of liquid crystal corresponding to 10 dropping liquid crystalline substances enters the space with regard to once entering into so, discharges a dropping liquid then brilliant ten times.
When cylinder component 300 needs that have piston 400 were changed, the piston 400 and the cylinder component 300 that just will be installed on the rotary drive unit 700 unloaded from this rotary drive unit 700, and new piston 400 and new cylinder component 300 are installed on this rotary drive unit.
Because the liquid crystal of specified rate once enters this and enters in the space, discharge the brilliant given number of times of a dropping liquid by nozzle unit then, so can will discharge on each panel area that marks on the substrate with the essentially identical amount of liquid crystal of benchmark amount of liquid crystal.
The distance that once glides by regulating piston, the just accurate mode weight of regulating the LC drop.
Piston minimizes along moving the scope that makes piston move with linearity that centers on same center line and circle in cylinder, thereby the mechanical realization of mobile piston in cylinder is oversimplified.
Because the utility model can embody under the situation that does not break away from its spirit or essential characteristic in a variety of forms, so should be understood that, unless stated otherwise, the foregoing description is not limited by any details of aforementioned description, and should be in its spirit and scope defined in the appended claims broadly explain, so claims are intended to comprise all changes and modification in the equivalent scope of the scope that falls into claim or this scope.
