Control part 8 possesses the central controlled microcomputer in each portion and the storage part (all not shown) storing various information and various programs etc., is arranged on (with reference to Fig. 1) in stand 7.Various information comprises and applies relevant coating information with cream, and this coating information is the information relevant with the spray volume of the setting value in the application pattern of regulation, depicting speed (applying coated surface and the nozzle 3a1 relative moving speed in the horizontal direction of object W), gap (setting value of the separating distance between the coated surface of the coating object W on the front end of nozzle 3a1 and workbench 2), cream etc.This control part 8 controls each portion based on various information, various program.
Wherein, here as application pattern, set the rectangular-shaped pattern possessing the limit parallel with X-direction and the limit parallel with Y direction.In addition, in the above description, configuration direction coating element 3A, 3C being mounted to the laser displacement gauge 3c of coating element 3A, 3C is along the object of Y direction, makes the light path face of laser displacement gauge 3c along the limit parallel with Y direction in application pattern.In addition, configuration direction coating element 3B, 3D being mounted to the laser displacement gauge 3c of coating element 3B, 3D is along the object of X-direction, makes the light path face of laser displacement gauge 3c along the limit parallel with X-direction in application pattern.
Next, laser displacement gauge 3c is described in detail.
Laser displacement gauge 3c is the analyzer measured the displacement of measuring object.That is, laser displacement gauge 3c is used for when in measurement range, measuring object moves from the position be originally positioned to other places, measures its amount of movement.Such as, if under the state being positioned at measurement range in the coated surface of coating object W, make laser displacement gauge 3c along X-direction or Y direction scanning mobile, then can measure the fluctuating of the coated surface on scanning motion track, the change of concavo-convex equal altitudes.Therefore, if while make laser displacement gauge 3c move along X-direction or Y direction scanning, while control Z axis mobile device 3b to maintain to make the measured value of laser displacement gauge 3c the value preset, then the interval between the front end of nozzle 3a and coated surface can be remained necessarily, carry out so-called clearance control.In addition, if under the state that laser displacement gauge 3c is fixed on Z-direction, laser displacement gauge 3c is scanned mobile to make it cross the cream applied by line, then because the height change of cream is embodied as measured value, so the coating height of cream can be obtained according to the variable quantity of measured value.
As shown in Figure 3, measure with the configuration direction of the light-projecting portion 3c1 of laser displacement gauge 3c and light accepting part 3c2, namely applied by line abreast with light path face the coating height of cream P time, under the state that the light path face of laser displacement gauge 3c is parallel with the bearing of trend of the cream P of wire, laser displacement gauge 3c scans according to the mode of the cream P crossing wire.
Thus, as shown in Figure 4, measured value (waveform) A1 of laser displacement gauge 3c can be obtained.Wherein, figure is the profile of cream P in fig. 4, the upper, and figure below is the measured value A1 of laser displacement gauge 3c.This measured value A1 illustrates the value extremely reducing this exception in the both ends measured value of the width of cream P.Its reason is, because the surface of the cream P at the both ends of the width of cream P is almost vertical plane, so from light-projecting portion 3c1 irradiation light hardly upward direction reflection, result, reverberation does not incide light accepting part 3c2 and can not measure.Measured value A1 beyond these both ends is the value suitable with the height of the cream of position.
Obtain the maximum of such measured value A1, as the coating height H of cream P.This coating height H is multiplied by the width L of cream P, and is multiplied by the constant K of regulation, calculate the sectional area S (S=H × L × K) of cream P thus.Wherein, constant K sets with experiment method or theoretical mode based on the prediction section shape (such as half-oval shaped) of the cream P after coating.In addition, the application width L of cream P obtains according to the image photographed by image pickup part 3d.
Here, as comparative example, to measure as shown in Figure 5 and the configuration direction of the light-projecting portion 3c1 of laser displacement gauge 3c and light accepting part 3c2, the coating situation highly of cream P that namely apply in line orthogonally with light path face are described.In this situation, under the state that the light path face of laser displacement gauge 3c is orthogonal with the bearing of trend of the cream P of wire, laser displacement gauge 3c scans according to the mode of the cream P crossing wire.
Thus, as shown in Figure 6, measured value (waveform) A2 of laser displacement gauge 3c can be obtained.Wherein, in figure 6, upper figure is the profile of cream P, and figure below is the measured value A2 of laser displacement gauge 3c.This measured value A2 illustrate the both ends of the width of cream P and inside it near abnormal value.Near the inner side at both ends, output the value larger than the measured value that should obtain.
Although can obtain the coating height H of maximum as cream P of such measured value A2, the coating height H now obtained is not apply height accurately.That is, because the exceptional value of the position near the inner side at the both ends of the width of cream P represents maximum, and this exceptional value is set as coating height H, so cause coating height H to become the value highly larger than the coating of reality.
Given this, when measuring the coating height H of cream P, as shown in Figure 3, make the light-projecting portion 3c1 of laser displacement gauge 3c parallel with the bearing of trend of the cream P of wire with the configuration direction of light accepting part 3c2, i.e. light path face, and laser displacement gauge 3c is scanned according to the mode of the cream P crossing wire.Thus, due to do not produce the both ends of the width of cream P inner side near the exceptional value of position, so can prevent this exceptional value from becoming coating height H, can obtain and apply height H accurately.
Next, the cream coating action that above-mentioned cream applying device 1 carries out is described.Wherein, the control part 8 of cream applying device 1 performs cream coating process based on various information and various program.
As shown in Figure 7, control part 8 controls each portion, carries out cream coating (step S1), then, obtains the sectional area (step S2) of the cream that the coated surface of coating object W applies, and finally, carries out quality and judges (step S3).Wherein, here sectional area is an example, as long as because whether the coating amount that can differentiate coated cream is in suitable scope, so can only measure coating height H, and judge based on its measured value, in addition, also can measure coating height H and application width L, and judge based on respective value.
In step sl, control part 8, in each coating element 3A ~ 3D, first utilized location mark (such as exist multiple) of image pickup part 3d to the coating object W on workbench 2 to take before cream coating.Then, control part 8 is detected the location mark photographed by image pickup part 3d by image recognition, determines the coating position applying cream in the coated surface of coating object W.
Next, control part 8 controls each coating element 3A ~ 3D, each X-axis mobile device 4A and 4B and each Y-axis mobile device 6A and 6B, while make coating object W on the nozzle 3a1 of each coating element 3A ~ 3D applicator head 3a separately and workbench 2 along its coated surface relative movement, while from the front end of the nozzle 3a1 of each applicator head 3a ejection cream, the coated surface of the coating object W on workbench 2 describes the application pattern (cream pattern) that multiple (such as 4) specify simultaneously.Wherein, control part 8 carries out this description repeatedly, the coated surface of the coating object W on workbench 2 is described to the application pattern of ormal weight.This ormal weight presets according to the size of coating object W, the size of application pattern.
In this description, control part 8 receives the measured value of the displacement of the coated surface of the coating object W exported from laser displacement gauge 3c in each coating element 3A ~ 3D.Then, the separating distance between the coated surface of the coating object W on the front end of the nozzle 3a1 of applicator head 3a and workbench 2, based on the measured value received, is maintained the setting value of the gap information stored in storage part by control part 8.Like this, the separating distance between the front end of nozzle 3a1 and the coated surface of coating object W is retained as setting value, and result can make the coating amount of cream coated in the coated surface of coating object W even.
Next, in step s 2, control part 8, for multiple application pattern coated in the coated surface of coating object W, carries out the detection of the coating height H of cream and the application width L of cream locating of presetting respectively.Here, the detection of the coating height H of cream utilizes each coating element 3A and 3B laser displacement gauge 3c separately to carry out.In addition, the detection of the application width L of cream is by utilizing each coating element 3A and 3B image pickup part 3d separately, and cream coated in the coated surface to coating object W is implemented shooting and carried out.Now, for other application pattern, also can use other coating element 3C and 3D, obtain the coating height H of cream and the application width L of cream as described above.Wherein, each coating element 3A ~ 3D is controlled to by control part 8 and carries out action with not hindering mutual action.
Here, above-mentioned locates such as when application pattern is rectangular box-like as shown in Figure 8, sets three positions to a line, and four lines set 12 positions (thick line with reference in Fig. 8) altogether.In addition, Fig. 8 is an example, and locating and measuring quantity is not limited to Fig. 8.And rectangular box-like application pattern is the one of the application pattern of the shape of two straight lines with crossover location relation.Specifically, one group of opposed limit is set as parallel with Y direction, and another opposed group limit is set as parallel with X-direction.Wherein, in this example embodiment, the limit (1st line B1 in Fig. 8 and 2nd line B2) parallel with Y direction is equivalent to the side's straight line in rectangular-shaped application pattern, and the limit (in Fig. 8 3rd line B3 and 4th line B4) parallel with X-direction is equivalent to the straight line of the opposing party.
When measuring above-mentioned rectangular box-like application pattern, using coating element 3A and 3B as one group, the 1st line B1 of the laser displacement gauge 3c of coating element 3A to application pattern is first utilized to carry out three position findings.Now, the bearing of trend of the light-projecting portion 3c1 of laser displacement gauge 3c and the configuration direction of light accepting part 3c2, i.e. light path face and the 1st line B1 (the cream P of wire), is similarly parallel with Fig. 3.Control part 8 utilizes X-axis mobile device 4A that the laser displacement gauge 3c of this parastate is moved along X-direction, scans in the mode of crossing the 1st line B1 along orthogonal direction.Carry out this scanning by each the locating of three positions, from three measured values obtained by these three times scanning, obtain respective maximum, as respective coating height H.Wherein, when asking for the coating height H of cream, the laser displacement gauge 3c be arranged in parallel by control part 8 option and installment direction (light path face) and the bearing of trend of cream is used.
Can should be undertaken by any one following method (but it is timid to be not only defined in any one following side) based on the selection of the laser displacement gauge 3c of control part 8.Such as, prestore in the storage part of control part 8 wired B1 ~ B4 and for the mensuration that applies height H laser displacement gauge 3c between relation (such as using this information of laser displacement gauge 3c of coating element 3A in the mensuration of the coating height H of the 1st line B1), control part 8 selects used laser displacement gauge 3c based on this information.Or, (the 1st line B1 is parallel with Y direction with the 2nd line B2 for the information relevant with shape that is application pattern that is that store in storage part based on control part 8,3rd line B3 and the 4th line B4 this information parallel with X-direction), control part 8 judges the direction of specifically coating height H being carried out to setting-out line, carrys out the laser displacement gauge 3c of selective light road surface along the line of determination object.
Next, control part 8 utilizes the laser displacement gauge 3c of coating element 3A to carry out three position findings to the 2nd line B2 opposed and parallel with the 1st line B1 with the 1st line B1.Now, control part 8 utilizes X-axis mobile device 4A as described above, make the bearing of trend of the configuration direction of laser displacement gauge 3c and light path face and the 2nd line B2 (the cream P of wire) be that the laser displacement gauge 3c of parastate moves along X-direction, scan according to the mode of crossing the 2nd line B2.Carry out this scanning by each the locating of three positions, obtain respective maximum, as respective coating height H from three measured values obtained by these three times scanning.
Then, control part 8 utilizes the laser displacement gauge 3c of the coating element 3B couple of 3rd line B3 orthogonal with the 1st line B1 to carry out three position findings.Now, configuration direction, i.e. the light path face of laser displacement gauge 3c are parallel with the bearing of trend of the 3rd line B3 (the cream P of wire).Control part 8 utilizes Y-axis mobile device 6A and 6B that the laser displacement gauge 3c of this parastate is moved along Y direction, scans according to the mode of crossing the 3rd line B3 along orthogonal direction.Carry out this scanning by each the locating of three positions, from three measured values obtained by these three times scanning, obtain respective maximum, as respective coating height H.
Finally, control part 8 utilizes the laser displacement gauge 3c of the coating element 3B couple of 4th line B4 opposed with the 3rd line B3 to carry out three position findings.Now, control part 8 utilizes Y-axis mobile device 6A and 6B, make the bearing of trend of the configuration direction of laser displacement gauge 3c, i.e. light path face and the 4th line B4 (the cream P of wire) be that the laser displacement gauge 3c of parastate moves along Y direction, scan according to the mode of crossing the 4th line B4.Carry out this scanning by each the locating of three positions, from three measured values obtained by these three times scanning, obtain respective maximum, as respective coating height H.
Like this, control part 8 obtains three coating height H to each line, obtains 12 coating height H altogether.Further, the coating height H of its cream to be multiplied with from the application width L taking the cream that image is obtained to each locating by control part 8, and is multiplied by the constant K of regulation to its value, calculates the sectional area S (S=H × L × K) of cream.Wherein, constant K as described above, based on the prediction section shape (such as half-oval shaped) of the cream after coating, and sets with experiment method or theoretical mode.Wherein, application width L is based on shooting image and calculating here, this shooting image be take continuously after the laser displacement gauge 3c at each painting wiring B1 ~ B4 place of locating separately scans, based on this shooting image located of image pickup part 3d.Control part 8 utilizes known image processing techniques, according to the shooting image of image pickup part 3d, detects the both ends being coated in the width of the cream of wire.Then, the distance between the both ends that detect is asked for, as the application width L of cream.
