As shown in Figure 1, comprise at least one nozzle 111 according to the LC divider of the embodiment of the present invention, by this nozzle, liquid crystal is assigned on substrate 10.
Nozzle 111 can move with respect to substrate.Nozzle 111 is connected in the nozzle cushion block (block) 112 that is installed in dispensing head unit 110.Dispensing head unit 110 is supported by head support frame 102, can move along a direction.The main body 101 of LC divider is fixed at the two ends of head support frame 102, can move along the direction of the perpendicular direction that moves with dispensing head unit 110.Therefore, the nozzle 111 that is installed in dispensing head unit 110 can move with respect to substrate 10.Particularly, nozzle 111 can move along directions X and Y-direction with respect to substrate, during distribution to keep the constant distance between nozzle 111 and substrate 10.
Feeding unit 120 forms the liquid crystal of the necessary datum quantity of LC layer on panel after nozzle 111 supplies.The cylinder of pump assembly 122 inside rotates according to the datum quantity of liquid crystal, with the panel zone drip liquid crystal drop on from nozzle 111 to substrate.There are a plurality of panel zones on substrate.Afterwards, during line and rupturing operation, the assembly of upper and lower substrate is divided into the panel of a plurality of separation.
Feeding unit 120 comprises syringe 121 and the pump assembly 122 that accommodates liquid crystal.Pump assembly 122 is exerted pressure to liquid crystal, with from nozzle 111 drip liquid crystal drop.The rotating opening of the cylinder of pump assembly 122 inside and close liquid crystal from syringe 121 to nozzle 111 stream, thereby on the panel zone of substrate drip liquid crystal drop.
Feeding unit 120 can comprise air pressure feeding unit and the valve of supplying air pressure.This air pressure feeding unit is to syringe 121 supply air or gases, with from nozzle 111 drip liquid crystal drop.This valve open and close liquid crystal from syringe 121 to nozzle 111 stream, thereby on the panel zone of substrate drip liquid crystal drop.Feeding unit 120 is not limited to said apparatus, but comprises any device that can control liquid flow path.
Two or more nozzles can be set, to distribute simultaneously the liquid crystal of datum quantity on two or more panel zones of large-size substrate.After the panel manufacturing, during line and rupturing operation, the assembly of upper and lower substrate is divided into the panel of a plurality of separation.Each panel is used in notebook computer, flat panel monitor and LCD televisor as display.
Before distributing, determine the datum quantity of liquid crystal, this is necessary to forming the LC layer later on panel.Then, the cylinder of pump component internal rotates according to the datum quantity of liquid crystal.So liquid crystal is assigned on panel zone with the form of drop.But actual allocated may be less than or more than the datum quantity of liquid crystal to the amount of liquid crystal on panel zone.This is attributable to be contained in the existence of the bubble in liquid crystal in syringe.That is, when rotational cylinder, may discharge bubble rather than liquid crystal.
Computing unit 130 determines whether to have distributed the liquid crystal of datum quantity on panel zone.For this reason, computing unit 130 calculates from the quantity of the liquid crystal drop of nozzle 111 instillation.Therefore, can automatically determine in fact whether to have distributed the liquid crystal of datum quantity on panel zone, check and need not to stop batch operation.
Computing unit 130 comprises sensor 131 and control module 141.
Sensor 131 sensing liquid crystal drops are from the instillation of nozzle 111.As shown in Figure 2, sensor 131 comprises the emission element 132 that emits beam and receives receiving-member 133 from the light of emission element 132.Emission element 132 and receiving-member 133 extend to the below of nozzle 111, nozzle 111 between both, thereby can and arrive receiving-member 133 through the below of nozzle 111 from the light of emission element 132.
As shown in Figure 3, emission element 132 can comprise a plurality of emitting heads.Therefore, no matter liquid crystal drop in which direction instils, and can both stop the light that sends from a plurality of emitting heads.That is the light that, sends from any one emitting head 132a can reflect (bounce off) from the liquid crystal drop that nozzle 111 tilts to instil.
Emission element 132 utilizes optical fiber to insert the injection moulding of plastics and makes.Two or more optical fiber are arranged in mold cavity (moldcavity) by row with regular interval with its simplest form, and then this mold cavity is closed and resin by injection.At this moment, the end as emitting head of each optical fiber is not covered by resin.A plurality of optical fiber can be with regular interval by row, by row or by going and being arranged in mold cavity by row, and then this mold cavity is closed also resin by injection.In this case, emitting head is listed as arrangement with regular interval by going, press to be listed as or to press row and press.
As shown in Fig. 4 A, thereby when the light that sends from emission element 132 can not receive light from the instillation drop of liquid crystal drop reflection receiving-member, the instillation of sensor 131 sensing liquid crystal drops.As shown in Figure 4 B, thereby when the light that sends from emission element can not receive light from the instillation reflection receiving-member of liquid crystal drop, the non-instillation of sensor 131 sensing liquid crystal drops.
In the situation that emission element 132 has a plurality of emitting heads, when receiving-member 133 did not receive all light that send from emitting head 132a, sensor 131 sensing liquid crystal drops were from the instillation of nozzle 111.
Sensor 131 can also comprise bottom 134.Bottom 134 prevents that liquid crystal drop from reflecting and returning between emission element 132 and receiving-member 133 from substrate 10.That is, bottom 134 prevents from dripping reflection from the light that emission element 132 sends from the primary event of liquid crystal.This has eliminated the possible dual error of calculation.
The middle part has the bottom 134 of opening 134a so that opening 134a just in time is positioned at the mode of nozzle 111 belows, is arranged on two lower ends of emission element 132 and receiving-member 133.Opening 134a is large must be enough to make liquid crystal drop to fall by this opening, and can not block.Bottom 134, emission element 132 and receiving-member 133 can form as one structure sensor 131.This can be connected in nozzle cushion block 112 with sensor 131 easily, and need not to adjust the position of emission element 132 and receiving-member 133.
The data that control module 141 provides according to sensor 131 are calculated from the quantity of the liquid crystal drop of nozzle 111 instillation, determine in fact distributed how many liquid crystal on each panel zone on substrate.Then, control module 141 determines by the calculating number of drop and the base value of drop are compared whether the actual allocated amount of liquid crystal has exceeded specification.
Base value is the number that needs the liquid crystal drop that instils on each panel.The base value of liquid crystal drop (RN) is obtained by following formula.
RN=datum quantity/DA
Wherein, datum quantity forms the necessary amount of liquid crystal of LC layer after being on each panel, and DA is the drop amount.When the calculating number of drop is less than or during more than base value (RN), control module 141 is determined the actual allocated amount of liquid crystal when exceeding specification.
Control module 141 can use the alarm unit (not shown) to make operating personnel notice that amount of liquid crystal has exceeded specification.
Control module 141 compares by actual allocated amount and the datum quantity with liquid crystal, can determine whether the actual allocated amount of liquid crystal has exceeded specification.Multiply by by the number with liquid crystal drop the actual allocated amount that DA (drop amount) calculates liquid crystal.When the actual allocated amount of liquid crystal is less than or during more than datum quantity, control module 141 is determined the actual allocated amount of liquid crystal when exceeding specification.
Control module 141 can be independent of the main control unit of the batch operation of controlling the LC divider and move.
Control module 141 can calculate by following formula the surplus (balance) of liquid crystal in syringe 121:
BA (surplus)=TA-(AA * DA),
Wherein, BA is remaining amount of liquid crystal in syringe 121, and TA is the liquid crystal total amount that initially is contained in syringe 121, and AA is the calculating number of liquid crystal drop.
In the calculating syringe of control module 141, the ability of liquid crystal surplus has been eliminated the demand of another device is installed, and this another device is used for detecting syringe 121 and whether has held the liquid crystal that is enough to carry out batch operation.
Before the beginning batch operation, control module 141 can detect the existence that remains in the liquid crystal drop on nozzle 111 tips.The existence of sensor 131 sensing liquid crystal drops on nozzle 111 tips.When liquid crystal drop instiled from nozzle 111 fully, the light that sends from emission element 132 reflected once from drop.But, resting on when liquid crystal drop on the tip of nozzle 111, the light that sends from emission element 132 continues from resting on the liquid crystal drop reflection on nozzle 111 tips.Therefore, control module 141 can detect the existence of liquid crystal drop on nozzle 111 tips by two different signals of sensor 131 sensings by identification.
Control module 141 can use the alarm unit (not shown) to make operating personnel notice that liquid crystal drop is present on nozzle 111 tips.So, dispensing head unit is moved to the convenient operation personnel remove liquid crystal drop from nozzle 111 tips position.
LC divider according to the present invention provides following advantage, determines automatically namely whether the actual allocated amount of liquid crystal exceeds specification, and the information of relevant liquid crystal surplus is provided and need not to install and measure in addition device.
Due under the prerequisite that does not deviate from spirit of the present invention or inner characteristic, the present invention can implement in a variety of forms, should also be appreciated that, except as otherwise noted, otherwise above-described embodiment is not limited to above-described any details, but should be in the spirit and scope of the present invention that claims limit extensive structure, therefore, drop in the boundary of claim and scope or all changes in the equivalent scope of these boundaries and scope and revising all will be comprised by claims.
