When the specification content of the adhesive is large, a screen of the adhesive data as shown in FIG. 23 may be displayed similarly to the nozzle code data described above. Specifications include viscosity, color, light and dark polarity, and appropriate temperature.

Further, the vertical movement and the rotation speed of the nozzle (6) may be adjusted according to the kind of the adhesive described above. That is, for example, when the viscosity of the adhesive is high, it causes stringing, so the rising speed is increased to suppress stringing, and when the viscosity is low, the adhesive is scattered when the nozzle (6) rotates. In order to prevent this, the rotation speed is controlled to be reduced.

Next, after touching the operation switch section of “return screen” at the lower left of the screen to return to the screen of “apparatus setting data”, and touching the operation switch section of “application pressure setting”, FIG. Is displayed. This screen is for setting the pressure to be applied to the syringe (7), and the respective operation switches of “gauge 1”, “gauge 2”, “gauge 3”, and “gauge 4” are displayed, as described above. When a desired operation switch section is touched, a screen for data setting is displayed on the display section and a "numeric keypad" is displayed, and the operator adjusts the pressure adjusting regulator to the desired application pressure by using the "numeric keypad". The set value is set. It should be noted that a regulator that can be adjusted automatically in conjunction with the application pressure set using the screen may be used.

Further, after touching the operation switch of "Return screen" to return to the screen of "device setting data", the operation switch of "Data edit" at the upper left of the screen is touched and the "Data edit" of FIG. The screen is returned to the "edit" screen, and the "offset data" operation switch is touched to display the "user password input" screen shown in FIG. When a specific worker inputs his / her password on this screen via a “numeric keypad”, a screen of “offset data” shown in FIG. 25 is displayed. On this screen,
There is an operation switch unit for each item of “device offset”, “nozzle offset”, “nozzle holder offset”, “camera offset”, and “camera gain / level”.
Normally, "offset data" is something that the user does not want to change unnecessarily, so that only a worker having a user password can display the "offset data" screen.

Touching the "nozzle holder offset" operation switch on the "offset data" screen displays the "nozzle holder offset" screen shown in FIG.

On this screen, X (horizontal), Y (vertical), and
There is an operation switch unit for setting an offset size with respect to the offset size of Z (angle) and R (eccentricity). For example, when an X (horizontal) operation switch of the nozzle (6) having the nozzle number 1 is touched, the switch is turned on, a display for data setting is displayed on the lower left of the screen, and “Nozzle 1 X” is displayed on the display. (Horizontal): ------- mm (The setting conditions up to now are displayed. No data is currently set.) "Is displayed, and the respective operation switches of the" numeric keypad "are displayed at the lower right of the screen. Is done. When the desired value (+1.23) is input by touching the operation switch section of the “numeric keypad”, the “−−−−” portion of the display section becomes “+1.2”.
"3" is displayed, and "+1.23" is set by touching the "set" key at the lower right, and the switch section is displayed as "+1.23".

Next, when the Y (vertical) operation switch of the nozzle (6) is touched, the switch is turned on and the display shows "Nozzle 1 Y (vertical): --- mm".
(The current setting condition is displayed. No data is currently set.) "Is displayed, and the desired value (+1.23) is input by touching the operation switch section of the" numeric keypad ". The “−−−−” portion of the display is “+1.2
"3" is displayed, and "+1.23" is set by touching the "Setting" key at the lower right, and the switch section is displayed as "+1, 23". Hereinafter, similarly, Z (angle) for nozzle rotation angle correction and R for nozzle eccentricity correction
(Eccentric) offset data is also set. Hereinafter, similarly, offset data is set for the nozzle (6) of another nozzle number.

Hereinafter, the operation will be described.

First, when the power is turned on, the CRT (25)
Displays the initial screen shown in FIG.

Touching the green operation switch for "production operation" on this initial screen displays the "production operation (application)" screen shown in FIG. When the start key (19) is pressed on this screen, the "stop" 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.

The substrate (1) is conveyed onto a chute from an upstream device (not shown), and the substrate (1) is positioned.

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 counter, which are usually the conditions for discarding the operation data in FIG. Since none of the number of substrates detected by (1) has reached the set value, the coating operation is started as it is. In addition, you may make it carry out unconditionally at the start of driving | operation. The coating operation is performed based on the NC data related to the coating operation shown in FIG. That is, in step 0001, the coordinate position (X) on the substrate (1) indicated by the X coordinate data [mm] or the Y coordinate data [mm].
An adhesive is applied to (1, Y1) at Z (angle data) Z1 under the application condition indicated by the application condition data shown in FIG. D (application condition data number) of the NC data in FIG. 14 is 001.
The nozzle (6) having the nozzle number 1 based on the nozzle number 1, the gauge 1, the coating time T1, and the coating diameter D1 set to 001 corresponding to the coating condition data in FIG.
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 on the top, and selection data (“Yes” or “No”) as to whether or not to recognize the application diameter is set in the application condition data. In this case, since “Yes” is set, the application diameter recognition operation is performed before the main application operation. Therefore, if the in-board recognition data (R) in the discard data shown in FIG. 19 is declared, the margin on the board (1) set in step 0011 indicated by the in-board discard step counter (not shown) The adhesive is applied to the X and Y coordinate positions of the portion. A CCD camera (1) is placed above the applied adhesive.
The XY table (4) is moved by driving the X-axis motor (2) and the Y-axis motor (3) so that 0) is positioned.

Then, the applied adhesive is recognized by the CCD camera (10). CPU based on this imaging result
The calculation device (not shown) in (17) calculates the diameter of the adhesive. This diameter is within an allowable range stored in the RAM (15) (for example, 0.8D1 ≦ calculated diameter ≦ 1.2D
It is determined by the CPU (17) whether or not it is in 1). If it is determined that the adhesive does not fall within the allowable range, the CPU (17) applies the adhesive during the main application operation in consideration of the deviation from the allowable range. That is, if the target application diameter D1 is supposed to be applied when the pressure is applied at the application time T1, but the actual diameter is DN by recognition, the CPU (17) adds DN to X in the above-described calculation formula.
Is substituted, and the value of t obtained as TN is calculated, and T1 +
During the main coating operation, the opening time of the discharge valve is controlled so as to be (T1-TN). In this case, since the multi-point hitting data in FIG. 16 is “one point”, Z1 is added to the coordinate position (X1, Y1) on the substrate (1) indicated by the NC data in FIG.
The adhesive is applied at one point in consideration of the angle correction data (--- (zero)) shown in FIG. If it is determined that the value falls within the allowable range, the main application operation is started as it is.

Next, in step 0002, since the application diameter recognition selection data is set to "no", the main application operation is performed as it is. Since the multi-point hitting data is set to “two points”, first, the first point is represented by the coordinate data (X2, Y
2) Z (angle data) of the first point in FIG. 18 is added to the position where the values set for the first point X (mm) and Y (mm) of the multi-pointing of the application condition data shown in FIG. 18 are added. The application time T2 is applied to the nozzle (6) of nozzle number 1 with the pressure of the gauge 2 at an angle taking into account the value set in the angle correction data shown in FIG.
Only the syringe (7) is pressed to apply the discharged adhesive. Subsequently, the second point X (m) of the multi-point hit data is set at the coordinate position (X2, Y2) on the substrate (1).
As described above, Z (angle data) of the second point in FIG. 18 is added to the position taking into account the values set for m) and Y (mm).
Is applied to the nozzle (6) of the nozzle number 1 with the pressure of the gauge 2 by the pressure of the gauge 2 at the angle taking into account the angle correction data of (2) to apply the discharged adhesive to the application diameter D2.
Apply with. In the case where multi-point hitting is performed, Z (angle data) set in the NC data is ignored. still,
The adhesive may be applied at an angle in consideration of Z (angle data) set in the NC data.

Subsequently, the coating operation after step 0003 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 “uncoated time” reaches the set uncoated time as shown in FIG. The discard number set before in "Number of discards" is discarded. At this time, the X-axis motor (2) and Y
The XY table (4) is moved by the drive of the shaft motor (3) to position the margin on the substrate (1) below the nozzle (6), and the syringe is supplied by air supplied through an air tube. In a state where the adhesive in (7) is discharged from the nozzle (6), the nozzle (6) is lowered, and FIG.
If the in-board discard data (W) is declared in the discard data shown in (1), the first discard is performed at the position set in step 0006 indicated by the in-board discard step counter. At this time, for example, if the “number of discards” is set to two, the second discard is performed in step 0007. Nozzles (6) with other nozzle numbers are similarly discarded based on each condition.

Next, the application operation is sequentially performed. Hereinafter, the operation of recognizing the application 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 next is, for example, the nozzle (6) of the nozzle number 1, the “actual number of coatings” is set as shown in FIG. When the actual number of application times is reached, the application diameter is recognized as described above. At this time, since “Yes” is set in “Dispatch operation” at the upper left of the screen, the discard operation is discarded by the “number of discards” set on the screen of FIG. If the in-board recognition data (R) is declared after this discarding operation, the margin on the board (1) set in step 0012 indicated by the in-board test hitting step counter (not shown) as described above. An adhesive is trial-shot at the X and Y coordinate positions of the portion. The application diameter of the test-struck adhesive is recognized by the CCD camera (10). X is set so that the CCD camera (10) is positioned above the margin of the substrate (1) on which the adhesive has been tested.
The Y table (4) is moved.

Then, the test-punched adhesive was applied to CC
Recognized by the D 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. The CPU determines whether or not this diameter is within the allowable range stored in the RAM (15).
It is determined by (17). If it is determined that the value falls within the allowable range, the operation returns to the main application operation. On the other hand, if it is determined that the adhesive does not fall within the allowable range, the CPU (17) applies the adhesive during the main application operation in consideration of the deviation from the allowable range. Also,
When the nozzle (6) to be used this time is, for example, the nozzle (6) having the nozzle number 4, the application diameter recognition operation condition is “all conditions” as shown in FIG. When any one of “time” and “number of substrates” satisfies the condition, the application diameter is recognized. At this time, "discard operation"
Is set to “No”, a test hit is performed in the blank portion of the substrate position without performing a discard operation before the main coating operation, and the application diameter of the test-struck adhesive is recognized. Based on the result, the main application operation is continued as described above. Also, as a result of recognition of the coating diameter, it was determined that the coating diameter did not fall within the allowable range, and the coating amount was adjusted during the main coating operation. The operation may be shifted to the application operation. That is, the trial hitting may be repeated. Hereinafter, the application diameter of the nozzle (6) of another nozzle number is similarly recognized based on each condition.
