The C data name is selected, and the operation switch of "operation data" in the displayed screen is touched to display the "operation data" screen shown in FIG. 7 and the like.

FIG. 7 shows a screen of "operation data" relating to the dispensing operation. The discard coating operation is a coating operation performed for cleaning the nozzle (6) before the main coating operation. In this screen, the conditions for discarding each nozzle (6) are set.
For example, the nozzle (6) of the nozzle number 1 is “operating condition”
Is set as “unapplied number of times” (based on the number of times of application by another nozzle (6) without using the nozzle (6)). That is, when the operation switch (upper left of the screen) for setting the operation condition for the nozzle (6) is touched, the switch is turned on, and the data setting display at the lower left of the screen displays "Nozzle 1 operating condition: ----". (The set operation conditions up to now are displayed. No data is currently set.) "Is displayed, and the operation switch section for each item of each condition is displayed at the lower right of the screen. When a desired (unapplied) operation switch is touched, the “−−−−” portion of the display section is displayed as “unapplied”, and by touching a “SET” key at the lower right. The “number of unapplied times” is set, and the lit switch section is displayed as the number of unapplied times. And the number of times of non-application is 100
It is set to times. That is, when the user touches the operation switch section for setting the number of unapplied times for the nozzle (6) of the nozzle number 1, the switch section is turned on and the display section displays "Nozzle 1 unapplied number: ----" The number of times is displayed. No data is currently set.) "Is displayed, and a" numeric keypad "(not shown) is used in place of the operation switch section of the operating condition for each item previously displayed at the lower right of the screen. Is displayed. The desired number of unapplied times (1
00), the “−−−−” portion of the display section is displayed as “100”, and by touching the “SET” key at the lower right, “100” is set and the lit switch section is set. Is displayed as 100. In addition, "
Is set to three times. Similarly, when the user touches an operation switch unit for setting the number of discards for the nozzle (6) of the nozzle number 1, the switch is turned on and the display unit displays “Nozzle 1 number of discards: −−−− (The number of times set so far is displayed. No data is currently set.) ”Is displayed. Then, when the desired number of discards (3) is input by operating the “numeric keypad”, the “−−−−” portion of the display section is displayed as “3”, and the “setting” in the lower right is displayed.
By touching the key, "3" is set, and the lit switch section is displayed as "3". That is, the fact that the number of times of non-application of the nozzle (6) has reached 100 is RA
When the counter (not shown) of M (15) counts, the discard operation is performed three times before the subsequent actual application operation. Hereinafter, data is similarly set for the other nozzles (6). That is, for the nozzle (6) of the nozzle number 2, the “operating condition” is “uncoated time” (based on the unused time measured by a timer (not shown)).
In this case, the time is set to 60 seconds, and the “number of discards” is set to two. That is, when the timer measures that the non-application time of the nozzle (6) has reached 60 seconds, the discard operation is performed twice as described above. Nozzle with nozzle number 3 (6)
Indicates that the “operating condition” is “the number of substrates”, the number of the substrates is 5,
The “number of times of discarding” is set to four times. That is, when the counter (not shown) in the RAM (15) counts that the substrate (1) on which the coating operation has been performed is discharged five times from the XY table (4) to the discharge conveyor (12) side. , The discard operation is performed four times. Further, for the nozzle (6) having the nozzle number 4, the “operating condition” is set to “all conditions” (“unapplied frequency”, “unapplied time”,
If any one of the conditions set in is satisfied, the discard is performed. ), The number of unapplied times is 50, and the unapplied time is 30
Seconds, the number of substrates is set to two, and the number of discards is set to one. In other words, the nozzle (6) performs the discard operation once if any of these operating conditions is satisfied.

Further, it is possible to prevent the discarding operation from being performed by touching the operation switch of "do not discard". When the user touches the “page feed” operation switch at the bottom center of the screen, a screen of “operation data” concerning the application diameter recognition operation shown in FIG. 8 is displayed. Note that the trial hitting coating operation is a coating operation performed for the purpose of recognizing the coating amount before the main coating operation. In this embodiment, in order to recognize the amount of application, the diameter (application diameter) of the adhesive applied to the substrate (1) is imaged by the CCD camera (10).

On this screen, conditions for performing the application diameter recognition automatic correction operation for each nozzle (6) are set. For example, for the nozzle (6) of the nozzle number 1, the “operating condition” is set to “actual application count” (based on the application count by the nozzle (6)). That is, the nozzle (6)
When the operation switch section (upper left of the screen) for which the operation condition is set is touched, the switch section is turned on, and “Nozzle 1 operating condition:
−−−− (The set operation conditions up to now are displayed. No data is currently set.) ”Is displayed, and the operation switch section for each item of each condition is displayed at the lower right of the screen. When a desired (actual number of application) operation switch portion is touched, the “−−−−” portion of the display section is displayed as “actual number of application”, and by touching a “setting” key at the lower right. “Actual application count” is set, and the lit operation switch section is displayed as the actual application count. The actual number of times of application is set to 1000 times. That is, when the user touches the operation switch section for setting the actual number of application times for the nozzle (6) of the nozzle number 1, the switch section is turned on and the display section displays "Nozzle 1 Actual Number of Application Times:
−−−− (The number of times set up to now is displayed. No data is currently set.) ”Is displayed and the operation switch of the operating condition for each item that has been displayed so far at the lower right of the screen is displayed. The operation switch unit of the “numeric keypad” shown in FIG. 9 is displayed instead of the unit. When the desired number of actual application times (1000) is input by operating the “numeric keypad”, the “−−−−” portion of the display section is displayed as “1000”, and the “SET” key at the lower right is touched. Is set to “1000”, and the illuminated operation switch unit is set to 1000
Is displayed. In addition, the "discard operation" is set to "Yes". Similarly, when the operator touches an operation switch section for setting the number of discards for the nozzle (6) of the nozzle number 1, the switch section is turned on and the display section is turned on. "Nozzle 1 discarding operation: --- (The previous setting is displayed.
Currently no data is set. )), And instead of the operation switches of the “numeric keypad” previously displayed at the lower right of the screen, operation switches (not shown) of “Yes” and “No” are displayed, and input “Yes” Then, the “−−−” portion of the display section is displayed as “Yes”, and is set to “Yes” by touching the “Setting” key at the lower right, and the display is performed when the lighted operation switch section is turned on. Is done. That is, when the counter (not shown) of the RAM (15) counts that the actual number of times of application of the nozzle (6) has become 1000, the discarding operation is performed, and then the application diameter recognition automatic correction operation is performed. Hereinafter, data is similarly set for the other nozzles (6). That is, for the nozzle (6) of the nozzle number 2, the “operating condition” is “actual application time” (based on the usage time measured by a timer (not shown)), and the time is 120.
The second is set to perform the "discard operation". That is,
When the timer measures that the actual application time of the nozzle (6) has reached 120 seconds, the discard operation is performed, and then the application diameter recognition automatic correction operation is performed. For the nozzle (6) with nozzle number 3, the “operating condition” is “substrate number” and the number is “1”.
0 sheets are set to perform the “discard operation”. That is,
The nozzle (6) confirms that a substrate presence / absence sensor (not shown) confirms that the applied substrate (1) has been discharged from the XY table (4) to the discharge conveyor (12) side.
When the counter (not shown) in 5) counts 10 times,
After performing the discarding operation, the application diameter recognition automatic correction operation is performed. The CPU (17) confirms that the coating operation has been performed up to the final step shown in FIG.
When the counter (not shown) in 5) has counted all the steps, the discarding operation may be performed, and then the application diameter recognition automatic correction operation may be performed. Further, the nozzle (6) of the nozzle number 4 satisfies one of the conditions set in the “operating condition” as “all conditions” (“the actual number of times of application”, “the actual application time”, and “the number of substrates”). Then, the application diameter recognition operation is performed).
Seconds, the number of substrates is set to 5, and the "discard operation" is set not to be performed. That is, when any of these operating conditions is satisfied, the nozzle (6) performs the application diameter recognition automatic correction operation without performing the discard operation.

Further, it is also possible to prevent the application diameter recognition automatic correction operation from being performed by touching the operation switch of "not recognized". It should be noted that a setting may be made such that a trial beating is always performed after the discard. Hereinafter, the operation will be described. First, when the power is turned on, the CRT (25) displays an initial screen shown in FIG. On this screen, operation switches for respective items of “production operation”, “setup work”, “data editing”, “device maintenance”, and “environment setting” are displayed.

When the green operation switch for "production operation" is touched on this initial screen, a screen for "production operation (application)" shown in FIG. 4 is displayed. Then, when the start key (19) is pressed in this screen, the "running" screen shown in FIG. 4 is replaced with the "running" screen shown in FIG. 5, and the production operation by the coating apparatus is started. At the start of operation, the number of unapplied times set in the counter of each nozzle (6), the unapplied time set in the discard timer, and the substrate detected by the counter, which are the conditions under which the operation data in FIG. Since none of the sheets has reached the set value, the application operation is started as it is. At the start of the operation, the driving may be performed unconditionally, or the test driving may be performed.

The coating operation is performed based on the NC data related to the coating operation shown in FIG. That is, step 000
In No. 1, the adhesive is applied to the coordinate position (X1, Y1) on the substrate (1) indicated by the X coordinate data [mm] or the Y coordinate data [mm] at the angle Z1 indicated by the angle data Z by the application condition data illustrated in FIG. Apply under the indicated application conditions. Note that “X” in FIG.
“1”, “Y1”, and “Z1” are all displayed as “1.00” as expedient numbers. Hereinafter, the same applies. D (application condition data number) of the NC data in FIG.
The nozzle number 1, the gauge 1, the coating time T1, and the coating diameter D1 (corresponding to "T1" and "D1" in FIG. 10) set to 001 corresponding to the coating condition data in FIG.
Are displayed as “999” and “9.99” for convenience. ) Based on nozzle number 1 (6)
Air is supplied from a supply source to the syringe (7) through an air tube (not shown) for the application time T1 by the pressure of the gauge 1 with the pressure of the gauge 1 to discharge a predetermined amount of the adhesive from the nozzle (6), and the substrate (1) is discharged. ), The adhesive is applied with an application diameter D1 (including an allowable range), and the application condition data further includes selection data (“Yes”, “Yes”, “Yes”, “Yes”) indicating whether or not to perform the application diameter recognition automatic correction operation. No) "is set.
In this case, since "Yes" is set, the coating diameter recognition automatic correction operation is performed before the main coating operation, and it is recognized whether or not the coating diameter D1 is actually obtained, and the coating diameter falls within the allowable range. If it is, the operation proceeds to the main application operation, and if it is not within the allowable range, the application operation is performed by adjusting the application time T1 (discharge time for supplying air to the syringe (7)) during the main application operation. The discharge pressure may be adjusted, or the discharge time and the discharge pressure may be adjusted. Therefore, the in-board recognition data (R) declaration (step 0010) in the discarded data shown in FIG. 11 is adhered to the X and Y coordinate positions of the blank area on the board (1) set in the next step 0011 set in the next step 0011. The agent is applied. When the test hitting is performed up to step 0014, the next test hitting is performed on the discard plate. The XY table (4) is moved by driving the X-axis motor (2) and the Y-axis motor (3) so that the CCD camera (10) is positioned above the applied adhesive. Then, the applied adhesive is recognized by the CCD camera (10). Based on this imaging result, the CPU (1
The calculation device (not shown) in 7) calculates the diameter of the adhesive. This is compared with the setting data (D1) stored in the RAM (15) by a comparing device (not shown) to determine whether or not the diameter is within an allowable range. If it is determined that the diameter does not fall within the allowable range, the CPU (17) corrects the deviation from the allowable range during the main application operation and adjusts the application diameter to be D1. Apply adhesive. If it is determined that the value falls within the allowable range, the main application operation in step 0001 is started.

Next, in step 0002, a coating time T2 is applied to the nozzle (6) of nozzle number 1 at an angle Z2 at the coordinate position (X2, Y2) on the substrate (1) with the pressure of the gauge 2 as well.
Only the inside of the syringe (7) is pressurized, and the discharged adhesive is applied with an application diameter D2. In this case, since the application diameter recognition selection data is set to "No", the main application operation is performed as it is. However, when the application diameter is adjusted to D1 in step 0001 described above, the amount is accordingly reduced. Is applied so as to obtain the application diameter D2.

Thereafter, the coating operation is continued in the same manner.
Hereinafter, the discard operation will be described. When the nozzle (6) to be used this time is, for example, the nozzle (6) of the nozzle number 2, when the “non-application time” reaches the set non-application time as shown in FIG. Number of discards "
Performs the discard count set in. At this time, the XY table (4) is moved by driving the X-axis motor (2) and the Y-axis motor (3), and a blank portion on the substrate (1) is positioned below the nozzle (6). With the adhesive in the syringe (7) being discharged from the nozzle (6) by the air supplied through the air tube, the nozzle (6) is lowered, and the substrate in the discard data shown in FIG. The position set in the next step 0006 which has been declared (W 0005) as the de-interpolated data (W) (6.00 and 6.00 are displayed as convenient numerals in FIG. 11; 0009 is a step for indicating the position of a blank portion on the substrate (1) where discarding can be performed.)
The first discard is performed. At this time, for example, if the “number of discards” is set to 2 times, 2
The second round is performed. Nozzles (6) of other nozzle numbers are similarly discarded based on each condition.

Next, the coating operation is sequentially performed. Hereinafter, the automatic correction operation for recognizing the coating diameter of the nozzle (6) will be described. When the main coating operation is performed based on each step, and the nozzle (6) to be used this time is, for example, the nozzle (6) of the nozzle number 1, the actual number of times of application is set as shown in FIG. When the number of application times has been reached, the application diameter recognition automatic correction is performed as described above. At this time, since "Yes" is set in the "discarding operation" at the upper left of the screen, the discarding operation is discarded by the "number of discards" set on the screen of FIG. If the in-board recognition data (R) has been declared after this discarding operation, as described above, the on-board test-strike step counter (not shown) sets a value on the board (1) set to step 0012. The adhesive is trial-shot at the X and Y coordinate positions in the margin. The application diameter of the test-struck adhesive is recognized by a CCD camera (10). The XY table (4) is moved so that the CCD camera (10) is positioned above the margin of the substrate (1) on which the adhesive has been tested. Then, an image of the test-struck adhesive is taken by a CCD camera (10). As described above, the calculation device (not shown) in the CPU (17) calculates the diameter of the adhesive based on the imaging result. This is compared with setting data (including an allowable range) stored in the RAM (15) by a comparing device (not shown), and it is determined whether or not the diameter is within the allowable range. And
If it is determined that it is within the allowable range, the operation returns to the main application operation as it is. On the other hand, when it is determined that the adhesive does not fall within the allowable range, the CPU (17) corrects the deviation from the allowable range and applies the adhesive during the main application operation. When the nozzle (6) to be used this time is, for example, the nozzle (6) with the nozzle number 4, the application diameter recognition automatic correction operation condition is “all conditions” as shown in FIG.
When any one of “the actual number of times of application”, “the actual application time”, and “the number of substrates” satisfies the condition, the application diameter automatic correction is performed. At this time, since the “disposal operation” is set to “not performed”, a test strike is performed on the blank portion of the substrate position without performing the discard operation before the main coating operation, and the adhesive of the test strike is used. The application diameter is recognized, and the main application operation is continued with or without adjusting the ejection time as described above based on the recognition result. In addition, when it is determined that the application diameter is not within the allowable range as a result of the application diameter recognition, the main application operation is performed by correcting the ejection time during the main application operation. After confirming that it has entered, the operation may be shifted to the main application operation. That is, the trial hitting may be repeated. Hereinafter, the application diameter recognition automatic correction operation is similarly performed for the nozzle (6) of another nozzle number based on each condition.

Further, the application operation is continued, and the remaining amount of the adhesive in the syringe (7) is detected by each remaining amount detecting sensor (33).
When detected in (34) and (35), discarding and trial hitting are performed as described above. That is, the ROM (1
According to the program stored in 6), when the remaining amount of the adhesive becomes a predetermined amount by the sensors (33), (34), and (35), the adhesive is discarded and the test is performed. At this time, the conditions for performing the discarding and the testing are data set for the corresponding nozzle (6) (see FIGS. 7, 8, and 9).
It is performed based on. That is, the nozzle (6) corresponding to the syringe (7) is, for example, the nozzle (6) of the nozzle number 1.
In the case of, the discarding operation is set to "Yes" as shown in FIG. 8, so that the discarding operation is repeated three times as shown in FIG. The application amount is recognized. Then, based on the recognition result, when the application amount is within the allowable range, the main application operation is performed as it is, and when the application amount is not within the allowable range, the application amount is adjusted during the main application operation. When the syringe (7) corresponds to the nozzle (6) of the nozzle number 4, the discarding operation is set to “not performed”, so that the test beating operation is performed without performing the discarding operation. The respective controls are performed during the main application operation based on the result of the operation of recognizing the application amount. Hereinafter, the discarding operation is similarly performed on the nozzle (6) of the other syringe (7).

In this case, condition data such as the number of discards and the number of test hits may be set in advance, or different data may be set according to each remaining amount. Hereinafter, before performing the main coating operation as described above, discarding or trial hitting is performed based on the program, and as described above, the coating diameter captured by the camera (10) is within an allowable range as a result of the test hitting. If so, the main application operation is started, and if the desired application diameter is not obtained, the adhesive is applied after correcting the deviation from the allowable range during the main application operation as described above.

Further, a program for discarding and performing test hitting when the remaining amount of the adhesive becomes a predetermined amount is stored in the ROM (16).
It may be stored in the AM (15). In the present embodiment, the application diameter is imaged by the camera and the application amount is recognized based on the result. However, the present invention is not limited to this. For example, the application amount may be recognized based on the area, volume, or the like. In the case of a multi-dot nozzle that can apply the adhesive shape, stringing state, and nozzle tip shape at multiple points, the application state such as the number of points is recognized,
A determination as to whether or not to perform automatic correction may be made based on the recognition result.

In the case where the above-described trial shot is performed and the coating amount is recognized, the recognition result may be stored in the RAM (15) and displayed on the screen as the coating amount recognition information. Thereby, as a result of the recognition operation, the apparatus determines that, for example, the test-struck adhesive is within the allowable range, and confirms that the operation has shifted to the main application operation. Further, the changed discharge time (or the discharge pressure or the discharge time and the discharge pressure) when the value does not fall within the allowable range may be displayed. That is, as shown in FIG. 13 which is an enlargement of the “device information” in FIG. 5, a set value (standard data) including a date, a nozzle number, and an allowable range, a measured value and a difference (±%) including the date and time of the recognition operation. The determination result (OK, NG), and in the case of NG, the changed application condition data (for example, ejection time, etc.) used during the main application operation is stored in the RAM (15), and a desired switch is touched. Display on the screen. Further, an imaging screen by the CCD camera (10) may be displayed, and the application shape of the applied adhesive may be displayed as an image based on the imaging result. Thereby, the application state to various nozzles can be confirmed. For example, the nozzle (6) is a two-point nozzle (6)
If the nozzle is a multi-dot nozzle, etc., the appropriate number (2)
