As shown in Figure 4, motherboard 10 is installed on the saddle 200.
The reference pattern data are input to control module.Move the nozzle 640 of coating head unit 600 according to the reference pattern data of input, thereby discharge fluid sealant, and on motherboard, form sealant pattern by nozzle 640.
Reference pattern changes according to the reference pattern data of input.
For the ease of explaining, suppose reference pattern by four each other the straight sealant pattern line p of right angle intersection formed.
The coating operation is described below.
When according to the reference pattern data of input when moving the nozzle 640 of coating head unit 600, first measuring unit, 650 continuous measurements that are arranged at coating head unit 600 are coated with the coating surface of motherboard 10 of fluid sealant and the distance between the nozzle 640 on it.
Laser displacement sensor as shown in Figure 3 comprises radiating portion 651, receiving unit 652 and output unit (not shown), described radiating portion 651 is transmitted into laser beam the motherboard 10 that is installed on the piece 620 in radiating portion 651 and motherboard 10 angled modes, described receiving unit 652 receives from the motherboard 10 laser light reflected bundles on the piece 620 to the end are installed in receiving unit 652 and motherboard 10 angled modes, the position data that described output unit arrives laser beam on the point of receiving unit 652 changes the signal of telecommunication into, and with the output of this signal of telecommunication, this signal of telecommunication represent and coating surface and nozzle between the data of distance dependent.
Laser displacement sensor is transmitted into the coating surface 11 of motherboard 10 by making radiating portion 651 continuously with laser, and receiving unit 652 is received from coating surface 11 laser light reflected bundles, thereby detects the distance between coating surface 11 and the nozzle 640.Distance between coating surface 11 and the nozzle 640 can obtain by utilizing vertical range between nozzle 640 and the laser displacement sensor and the distance between laser displacement sensor and the coating surface 11.
Use with negative of comparing to set a distance or positive number with the data of distance dependent and to represent.
As shown in Figure 5, the data with distance dependent are plotted on the connecting line curve map.X-axis on this curve map shows the path that nozzle (perhaps first measuring unit) is advanced according to the reference pattern data, and the Y-axis on this curve map shows the distance between nozzle and the coating surface 11.Be shown on this curve map at the nozzle at set point place on the X-axis and the distance between the coating surface 11.
When the Y-axis numerical value at set point place on the X-axis is-3, and the distance between putting on the corresponding nozzle 640 of set point and surperficial 11 on the X-axis is less than giving set a distance.That is, if be assumed to 40 microns to set a distance, the distance between corresponding with set point on the X-axis so nozzle 640 and the surface 11 is 37 microns.
When X-axis or Y direction move coating head unit 600, moving nozzle 640.By according to the data of the distance dependent that obtains by first measuring unit 650, move up and down nozzle 640, keep between nozzle 640 and the coating surface 11 give set a distance the time, through nozzle 640 discharge fluid sealants.Need between nozzle 640 and coating surface 11, constantly keep given distance, thereby keep the width and the uniformity highly of the pattern lines of sealant pattern.
As shown in Figure 6, be shown on the display unit, wherein as a setting based on the pattern image P of reference pattern data for range image G with the data of distance dependent.Display unit can comprise monitor.
If pattern image P by four each other the straight pattern lines of right angle intersection formed, so by four each other the sealant pattern formed of the straight pattern lines of right angle intersection be formed on the motherboard.Therefore, range image G is presented on the monitor, and wherein identical with sealant pattern pattern image P as a setting.
In the range image G that the pattern image P in background shows, when equating when the measuring distance between nozzle and the coating surface 11 with to set a distance, demonstrate " 0 (zero) " difference on four straight pattern lines of composition pattern image P, when the measuring distance between nozzle and the coating surface 11 when giving set a distance, form within four straight pattern lines of pattern image P or outside demonstrate error, when the measuring distance between nozzle and the coating surface 11 when giving set a distance, form outside four straight pattern lines of pattern image P or within demonstrate error.
For example, when with reference pattern image P on corresponding, the nozzle of set point P1 and coating surface 11 on set point between distance and when equating to set a distance, the distance table at set point P1 place is shown as " 0 " on the straight pattern lines of reference pattern image P.When and reference pattern image P on corresponding, the nozzle of set point P2 and the measuring distance between the set point on the coating surface 11 when giving set a distance, then the distance table at set point P2 place is shown " (negative) " outside the straight pattern lines of reference pattern image P.When and reference pattern image P on corresponding, the nozzle of set point P3 and the measuring distance between the set point on the coating surface 11 when giving set a distance, then the distance table at set point P3 place is shown "+(positive number) " within the straight pattern lines of reference pattern image P.
Otherwise, when and reference pattern image P on corresponding, the nozzle of set point P2 and the measuring distance between the set point on the coating surface 11 when giving set a distance, then the distance table at set point P2 place is shown " (negative) " within the straight pattern lines of reference pattern image P.When and reference pattern image P on corresponding, the nozzle of set point P3 and the measuring distance between the set point on the coating surface 11 when giving set a distance, then the distance table at set point P3 place is shown "+(positive number) " outside the straight pattern lines of reference pattern image P.
In range image G, measuring distance and represent for the difference between the set a distance with colour.Measuring distance and represent for positive difference and negative difference between the set a distance with different colours.For example, positive difference represents with redness and negative difference is represented with blueness, and is perhaps opposite.In addition, measuring distance and can represent for positive difference and negative difference between the set a distance with same color.
In range image G, measuring distance and big more to the difference between the set a distance, the color relation of expression difference is dark more.
With measuring distance with to the bilateral tolerance relevant apart from difference between the set a distance is can be predetermined.This bilateral tolerance is defined as and the plus or minus deviation of giving set a distance.By using the summation that cuts measuring distance and bilateral tolerance to set a distance, can obtain the range deviation data.For example, suppose that distance between the set point on nozzle and the coating surface 11 through being measured as 48 microns, be set at 40 microns to set a distance, and bilateral tolerance is set at 4 microns (error ranges from 36 to 44).In this case, the distance between the set point on nozzle and the coating surface is+4.Like this, be presented on the monitor, wherein as a setting based on the pattern image of reference pattern data based on the range image G of range deviation data.Range image based on the range deviation data replaces to colour on monitor.
When range image G is presented on the monitor, wherein reference pattern image P can with the naked eye see the bigger difference between delivery nozzle and the coating surface 11 as a setting the time easily.Like this, can with monitor on the point that shows zone corresponding, that be formed on the sealant pattern on the motherboard than the big difference place show as zone to be looked into.
In range image G, measuring distance and big more to the difference between the set a distance, the color relation of expression difference is dark more.In this case, can with monitor on show show as zone to be looked into than the corresponding zone that is formed on the sealant pattern on the motherboard of dark colour point.
There is several different methods that the zone to be looked into of shown sealant pattern is checked.For example, can utilize amplifying lens by the shown zone to be looked into of visual inspection.
But the zone to be looked into that automatic inspection is shown.For this reason, on coating head unit 600, be provided for measuring second measuring unit of the sectional area of sealant pattern.Coating head unit moves near the zone is looked in shown waiting, thereby makes second measuring unit measure this regional sectional area.After this, whether determining shown waiting, to look into the zone up to specification.Automatically be input in the control module looking into the relevant information in zone with shown waiting.
Fail when up to specification when shown zone to be looked into, look on the zone in shown waiting and do over again.In the time can not doing over again on the defectiveness zone at sealant pattern, prevent from liquid crystal droplet further is discharged within this defective sealant pattern.
When moving coating head unit 600 according to the reference pattern data, the distance between the coating surface of motherboard and the nozzle 640 is inconsistent.This is because the surface of motherboard is uneven, and the motion of coating head unit 600 produces vibration, and guide member does not have precision and guides the motion of dispense tip 600 exactly.The inconsistency of distance has caused the sectional area of sealant pattern irregular between coating surface and the nozzle.
In order to prevent these, by according to 650 that obtain by first measuring unit, with coating surface 11 and nozzle 640 between the data of distance dependent move up and down nozzle 640, keep between coating surface and the nozzle 640 to set a distance.Yet in the range image that shows on monitor, the big distance between first measuring unit 650 and the coating surface 11 shows and moves up or down nozzle 640 dramatically.The sectional area that the moving up and down of nozzle 640 very big degree causes sealant pattern irregular.Thus, can will exist the zone of above-mentioned big distance to show in the sealant pattern between first measuring unit 650 and the coating surface 11 as zone to be looked into.
As mentioned above, since demonstrate on the monitor based on and the coating surface of nozzle and motherboard between the range image of data of distance dependent, and based on the pattern image of reference pattern data, wherein therefore pattern image can be predicted sealant pattern and how to be formed on the motherboard substrate as a setting.
In addition, the colour on the occasion of distance or negative value distance between coating surface and the nozzle represents to make it possible to recognize the zone to be looked into of sealant pattern.
And, can make things convenient for and demonstrate apace the zone to be looked into of the sealant pattern that is formed on the motherboard, and not need to check the All Ranges that is formed on the sealant pattern on the motherboard.
, the present invention do not break away from its spirit and essential characteristics because can specializing in a variety of forms, what therefore should know is, arbitrary details that the foregoing description is not described in the preamble limits, unless otherwise indicated, otherwise should be interpreted as widely, be in as within the spirit and scope defined in the claims, so claims are intended to contain all changes and modification within the equivalent of the generally acknowledged scope that drops on claim or this scope.
