The operation will be described below.

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

When the green operation switch for "production operation" is touched on the initial screen, the "production operation (application)" screen shown in FIG. 5 is displayed. 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.

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 conditions for discarding the operation data in FIG. 10, are usually detected. Since none of the number of substrates 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, step 000
In FIG. 15, the adhesive is indicated by Z (angle data) Z1 at the coordinate position (X1, Y1) on the substrate (1) indicated by the X coordinate data [mm] or the Y coordinate data [mm] by the application condition data shown in FIG. Apply under the application conditions. D of NC data in FIG.
(Coating condition data number) is set to 001, and the nozzle of nozzle number 1 is set based on the nozzle number 1, gauge 1, coating time T1, and coating diameter D1 set to the corresponding 001 of the coating condition data in FIG. In (6), the adhesive is applied by the pressure of the gauge 1 to the syringe (7) through an air tube (not shown) from the supply source for an application time T1 to discharge a predetermined amount of the adhesive from the nozzle (6). The adhesive is applied on the substrate (1) with an application diameter D1, and selection data ("Yes" or "No") for determining 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) Part X,
An adhesive is applied to the Y coordinate position. 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). CPU based on this imaging result
The calculation device (not shown) in (17) calculates the diameter of the adhesive. This is stored in a RAM (15) by a comparison device (not shown).
Is compared with the setting data (including the permissible range) stored therein, and it is determined whether or not the diameter is within the permissible range. If it is determined that the adhesive does not fall within the allowable range, the CPU (17) adjusts the application amount in consideration of the deviation from the allowable range during the main application operation, and applies the adhesive. . In this case, since the multi-point hitting data in FIG. 16 is "-" (one point), the coordinate position (X1, Y1) on the substrate (1) shown 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.

Thereafter, 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, and the operation of recognizing the application 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 is, for example, the nozzle (6) having 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, this test-struck adhesive is 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. 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 falls within the allowable range. 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) adjusts the application amount in consideration of the deviation from the allowable range during the main application operation, and applies the adhesive. Further, when the nozzle (6) to be used this time is, for example, the nozzle (6) of the nozzle number 4, the application diameter recognition operation condition is “all conditions” as shown in FIG. If either of the “actual application time” and the “substrate number” satisfies the condition, the application diameter is recognized. At this time,
Since “No” is set in “Non-operation”, a test is performed in the blank portion of the substrate position without performing the non-operation before the main application operation, and the application diameter of the test-applied adhesive is determined. The main application operation is continued as described above based on the recognition result. 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.

As described above, according to the present invention, the number of application steps can be reduced by setting the data for performing the application operation when applying the application agent to several parts in one part.
