The Nozzle Temperature Setting screen is displayed. On this screen, for each nozzle 6, "nozzle 1", "nozzle 2", "nozzle 3", "nozzle 4" operation switch parts and "P (proportional) constant", "I (integral) constant", "D
A display unit for displaying each value of "(differential) constant" and "nozzle temperature set value" is displayed. On this screen, when the operation switch portion of the "nozzle 3" for designating the nozzle 6 of the nozzle number 4 is touched, when the operation key 20 is pressed after the switch portion is turned on, the nozzle 6 of the nozzle number 3 becomes the ROM1.
Based on the standard value in P.6, the heater 8 is set to P.
I. The temperature control operation is performed by D control. In addition, R is displayed on the display unit.
The standard value stored in the OM 16 is displayed.

In the following, the nozzle 6 having the nozzle number 4 is also subjected to the temperature control operation by a desired method from the above-mentioned embodiments of the nozzle temperature setting. The operation will be described below. First, it will be described below that the program for performing the dispensing coating operation stored in the ROM 16 is selected by a selection device (not shown).

When the power is turned on, the CRT 25 displays the initial screen shown in FIG. When the operation switch section of "production operation" is touched on this initial screen, the screen of "production operation (application)" shown in FIG. 4 is displayed. When the start key 19 is pressed on this screen, the "stopping" screen shown in FIG. 4 is replaced with the "running" screen shown in FIG. 5, and the production operation by the coating device is started.

Here, the production operation is not started until each nozzle 6 reaches a desired temperature based on each condition set on the nozzle temperature setting screens of FIGS. 16 to 19. Also,
At the start of operation, the number of non-applications set in the counter of each nozzle 6, which is a condition for discarding the operation data of FIG. 10, the non-application time set in the discard timer, and the number of substrates detected by the counter are normally set. Since neither of them has reached the set value, the coating work is started as it is.
It should be noted that when the operation is started, the discarding may be performed unconditionally.

The coating work is performed based on the NC data regarding the coating operation shown in FIG. That is, step 000
In No. 1, the adhesive is applied at the coordinate position (X1, Y1) on the substrate 1 indicated by the X coordinate data (mm) and the Y coordinate data (mm) at Z (angle data) Z1 as indicated by the application condition data shown in FIG. Apply under the conditions. The D (application condition data number) of the NC data of FIG. 20 is set to 001, and FIG.
No. 1, gauge 1, application time (pressurization time) T1 set to corresponding 001 of the application condition data of No. 1, and adhesive 6 is applied to nozzle No. 1 with a pressure of gauge 1 based on application diameter D1. Air is sent from the supply source to the syringe 7 through the air tube (not shown) for a time T1 to discharge a predetermined amount of the adhesive from the nozzle 6, and the adhesive is applied onto the substrate 1 at the application diameter D1. Further, in the coating condition data, selection data (“Yes” or “No”) for recognizing the coating diameter is set. In this case, “Yes” is set. The coating diameter recognition operation is performed. Therefore, if the in-board recognition data (R) in the discarding data shown in FIG. 22 is declared, the blank portion on the substrate 1 set in step 0011 indicated by the in-board discarding step counter (not shown) Adhesive is applied to the X and Y coordinate positions. The X-axis motor 2 and Y are arranged so that the recognition camera 10 is positioned above the applied adhesive.
The XY table 4 is moved by driving the shaft motor 3.

Then, the applied adhesive is recognized by the recognition camera 10. A calculation device (not shown) in the CPU 17 calculates the diameter of the adhesive based on the image pickup result. This is compared with setting data (including a permissible range) stored in the RAM 15 by a comparison device (not shown) to determine whether or not the diameter is within the permissible range. If it is determined that the value is not within the allowable range, C
The PU 17 adjusts the discharge amount of the adhesive by correcting the application time in consideration of the deviation from the allowable range during the main application operation, and applies the adhesive. If it is within the allowable range, the main coating operation is performed under the same conditions. It should be noted that there are a plurality of coating points to be recognized when recognizing the coating diameter, and an average value of arbitrary recognition data among them (for example, 5 points are recognized, and an average value of 3 points excluding the maximum value and the minimum value) is calculated, The correction may be applied at the next main application.

Next, in step 0002, the same substrate 1 is used.
Nozzle number 1 at angle Z2 at upper coordinate position (X2, Y2)
The inside of the syringe 7 is pressurized to the nozzle 6 with the pressure of the gauge 2 for the application time T2, and the discharged adhesive is applied with the application diameter D2. In this case, since the coating diameter recognition selection data is set to "not", the main coating operation is performed as it is.

Thereafter, the coating operation is continued in the same manner.
The discarding operation will be described below. When the nozzle 6 to be used next time is, for example, the nozzle 6 having the nozzle number 2,
When the “uncoated time” reaches the set uncoated time as indicated by 0, the number of rounding off is set to “number of rounding off” before the main coating operation. At this time, the XY table 4 is moved by driving the X-axis motor 2 and the Y-axis motor 3, the blank space on the substrate 1 is positioned below the nozzle 6, and the air supplied through the air tube is used. With the adhesive in the syringe 7 being discharged from the nozzle 6,
If the nozzle 6 is lowered and the in-board discard data (W) in the discard data shown in FIG. 22 is declared, the first discard is performed at the position set in step 0006 indicated by the in-board discard step counter. Hitting is done. At this time, for example, if the "discard count" is set to 2, step 00
A second round-down is done at 07. The nozzles 6 having other nozzle numbers are similarly discarded based on each condition.

Next, the coating operation is sequentially performed, and the operation of recognizing the coating diameter of the nozzle 6 will be described below. When the main coating operation is performed based on each step and the nozzle 6 to be used next time is, for example, the nozzle 6 having the nozzle number 1, the “actual coating number” reaches the set actual coating number as shown in FIG. Then, the coating diameter is recognized as described above. At this time, the discarding operation is discarded by the number of "discarding times" set on the screen of FIG. 10, and if the in-board recognition data (R) is declared after this discarding operation, as described above, The adhesive is trial-blended at the X and Y coordinate positions of the blank portion on the substrate 1 set in step 0012 indicated by the inner trial-blank step counter (not shown). The camera 10 recognizes the coating diameter of the adhesive that has been trial-strike.

The XY table 4 is arranged so that the camera 10 is positioned above the margin of the substrate 1 on which this adhesive has been trial-printed.
To move. Then, the camera 10 recognizes the adhesive that has been trial-dried. As described above, the calculation device (not shown) in the CPU 17 calculates the diameter of the adhesive based on the result of this imaging. This is RAM15 by the comparison device not shown.
It is judged whether or not the diameter is within the allowable range by comparing with the setting data (including the allowable range) stored in the inside. Then, when it is determined that it is within the allowable range, the process directly returns to the main coating operation. If it is determined that the value is not within the allowable range, the CPU 17
Adjusts the discharge amount by correcting the pressurizing time in consideration of the deviation from the allowable range during the main application operation, and applies the adhesive. When the nozzle 6 to be used next time is, for example, the nozzle 6 having the nozzle number 4, the coating diameter recognition operation condition is “all conditions” as shown in FIG.
The coating diameter is recognized when either the “actual coating time” or the “number of substrates” satisfies the condition. At this time, since the "discarding operation" is set to "not", the disposing operation is not performed before the main coating operation, and the marginal portion of the substrate position is subjected to the trial striking. The coating diameter is recognized, and the main coating operation is continued based on the recognition result as described above. Also, as a result of recognition of the coating diameter, it was determined that it was not within the allowable range, and the discharge amount was corrected during the main coating operation. You may make it move to a coating operation. That is, the trial striking may be repeated. Further, in order to adjust the coating diameter, the pressing force may be adjusted, or both the pressurizing time and the pressing force may be adjusted. Less than,
The coating diameters of the nozzles 6 having other nozzle numbers are similarly recognized based on the respective conditions.

Next, a case will be described in which the application amount adjusting operation program stored in the ROM 16 after the predetermined non-use time has elapsed is selected by the selecting device. The application work is
The NC shown in FIG. 20 stored in the storage device as described above.
Based on the data, in step 0001, the adhesive is applied at the coordinate position (X1, Y1) on the substrate 1 indicated by the X coordinate data (mm) and the Y coordinate data (mm) by Z (angle data) Z1 as shown in FIG. Apply under the application conditions indicated by the data. NC data D of FIG. 20 (coating condition data number)
Is set to 001, and the nozzle number 1, the gauge 1, and the nozzle number 1 set to 001 corresponding to the coating condition data of FIG.
Based on the application time (pressurizing time) T1 and the application diameter D1, the adhesive is applied to the nozzle 6 of the nozzle number 1 with the pressure of the gauge 1 into the syringe 7 for the application time T1 from the supply source through the air tube (not shown). The predetermined amount of adhesive is ejected from the nozzle 6 to apply the adhesive with a coating diameter D1 onto the substrate 1. Further, the coating condition data includes selection data (whether or not to recognize the coating diameter). Since “Yes” and “No” are set, and in this case “Yes” is set, the coating diameter recognition operation is performed as described above before the main coating operation, and the predetermined coating operation is performed. . After the completion of the coating operation by the nozzle 6, the timer 28 counts the non-use time of the nozzle 6.

Next, in step 0002, the same substrate 1 is used.
Nozzle number 2 at angle Z2 at upper coordinate position (X2, Y2)
The inside of the syringe 7 is pressurized to the nozzle 6 with the pressure of the gauge 2 for the application time T2, and the discharged adhesive is applied with the application diameter D2. In this case, since the coating diameter recognition selection data is set to "not", the main coating operation is performed as it is. After the completion of the coating operation by the nozzle 6, the timer 28 counts the non-use time of the nozzle 6.

Next, in step 0003, the same substrate 1 is used.
Since the nozzle 6 having the same nozzle number 2 as in the step 0002 is used at the upper coordinate position (X3, Y3) at the angle Z3, the timer 28 times up, at which time the RAM
If the specified non-use time stored in 15 is not exceeded, CP
When U17 determines, the inside of the syringe 7 is pressurized to the nozzle 6 with the pressure of the gauge 1 for the application time T3, and the discharged adhesive is applied with the application diameter D2. In this case, since "Yes" is set in the coating diameter recognition selection data, the main coating operation is performed after the coating diameter recognition operation is performed as described above. After the completion of the coating operation by the nozzle 6, the timer 28 counts the non-use time of the nozzle 6.

Thereafter, the coating operation after step 0004 is performed in the same manner. Then, in the case where the coating operation is performed again with the nozzle 6 having the nozzle number 1 in step 0010, it is assumed that the non-use time of the nozzle 6 is up by the timer 28, which will be described below. Step 0010
The CPU 6 determines that the nozzle 6 having the nozzle number 1 used in No. 1 has not been used for a predetermined time.
The main coating operation is performed based on each data of the premium rate or the discount rate set on the screen of FIG. That is, A% is added to the coating time (pressurization time) T10 set in step 0010 based on the A% set via the first operation switch section of the nozzle 6 of the nozzle number 1. The value is calculated by the calculation device in the CPU 17, and the compressed air is applied to the syringe 7 for the calculated pressurizing time to eject the adhesive. As a result, the desired coating amount (coating diameter) D10
Is obtained.

When the second coating is performed by the nozzle 6 having the nozzle number 1, the main coating operation is similarly performed by adding B% to the pressurizing time stored in the RAM 15. Below 3
The same applies to the points after that, and the RAM 1 is used after the fifth point after the pressurizing time is adjusted up to the fourth point by the nozzle 6.
Air is applied according to the pressurizing time data stored in 5, and the coating operation is performed.

Similarly, when the timer 28 corresponding to each nozzle 6 similarly counts the elapse of the predetermined non-use time of the nozzle 6, the pressurizing time is calculated based on the premium rate or discount rate set on the screen of FIG. It is adjusted and the main coating operation is performed. In the present embodiment, when the first several points are applied after the predetermined non-use time set in the drawing of FIG. 11 is applied (for example, the first to fourth points).
Although the coating amount adjustment operation is performed at the (point) and the regular coating operation is performed from the fifth point, for example, a cancel button as a release device for ending the coating amount adjustment operation is displayed on the screen of the production operation in FIG. It may be prepared so that the operator can finish the coating amount adjusting operation at an arbitrary timing.

[0049]

As described above, according to the invention of claim 1, at least one of the pressurizing force and the pressurizing time is increased without discarding the first several points at the start of coating after a predetermined non-use time has elapsed. Alternatively, since the coating operation is performed at a discount, stable coating can be performed from the first point after the restart.

According to the second aspect of the invention, at least one of the pressurizing force and the pressurizing time is increased or discounted without discarding the first several points at the start of application after the predetermined non-use time has elapsed. So that the coating operation is performed,
Stable application is possible from the first point after restart,
The release device can release the control at an arbitrary timing when the operation of adjusting the pressurizing force or the pressurizing time becomes unnecessary, which is convenient for use.

Furthermore, according to the invention of claim 3, at least one of the pressurizing force and the pressurizing time is not applied to the first several points at the start of the application after the predetermined non-use time has elapsed, and at least one of the applied pressure and the pressurizing time is applied to each point. Since the coating operation is performed with a premium or a discount, the stability of the coating amount at each point after restart is improved.
