Position control of 3, 8 and 11 is performed.

First, the servo motors 4, 6, 8a, 12

Measure the height of a. The Z-axis driver 17i uses this measurement result to drive-control the servo motor 12 and always maintain the height of the nozzle 13a constant.

Next, the operation of the apparatus in this embodiment will be described with reference to FIG.

In FIG. 4, when the power is turned on (step 100), the initial setting of the paste applicator is first executed (step 200). In this initial setting step, the substrate holding mechanism 7 is moved in the X, Y, and θ directions and positioned at a predetermined reference position by driving the servo motors 4, 6, and 8a in FIG. Further, the servo motor 12 is driven to set the nozzle 13a to a predetermined origin position so that the paste discharge port is at the position where the paste application starts (that is, the paste application start point). Further, all the data relating to the application of the paste pattern of the type set when the paste application machine was stopped last time and the board position data are set.

Input of such data is performed from the keyboard 20 (FIG. 1), and the input data is stored in the RAM built in the microcomputer 17a (FIG. 3) as described above.

When the initial setting process (step 200) is completed, the substrate 9 is carried in and mounted on the substrate holding mechanism 7 (FIG. 1) and held (step 300).

When the above steps are completed, a coating drawing condition reading process (step 400) is then executed.

The process of reading the coating drawing condition will be described with reference to the drawings. FIG. 5 is a plan view showing a specific example of the substrate 9 on which the paste pattern is applied and drawn.
PP6 is a paste pattern for coating and drawing, and DA is a coating and drawing condition for the paste pattern. In this embodiment,
A plurality of paste patterns P having substantially the same shape on the same substrate 9
P1 to PP6 are drawn.

In FIG. 5, coating drawing conditions DA of the paste patterns PP1 to PP6 to be applied and drawn are recorded on the substrate 9. The paste pattern coating / drawing condition DA is recorded and formed in an area on the substrate 9 where the paste pattern is not coated / printed.

FIG. 6 is a diagram showing a specific example of the contents of the coating drawing condition DA.

In the drawing, the coating and drawing conditions DA include the following five items, that is, the comprehensive information PD of the paste pattern.
1, layout information PD2, inspection information PD3, paste pattern shape information PD4, and application condition information PD5.

The paste pattern general information PD1 is data relating to the type of paste pattern to be applied in relation to the type of substrate, and the arrangement information PD2 is the start position data and application sequence data of the paste pattern to be applied on the substrate. It consists of The inspection information PD3 is condition data (for example, width, height, perimeter, measurement pitch, measurement position, inspection processing conditions, etc. as measurement items) for inspecting the paste pattern applied on the substrate. The shape information PD4 is the shape data (vertex coordinate data) of the paste pattern applied on the substrate. The coating condition information PD5 is data of coating conditions of the paste pattern to be coated on the substrate (for example, coating speed, coating pressure, nozzle gap, coating condition switching position data and valid / invalid setting data). Recording of such information on the substrate is performed by laser drawing, ink jet printing, photolithography process, or the like.

In step 400 of FIG. 4, each data of the coating drawing condition DA recorded on the substrate 9 is attached to the head portion (the portion including the paste storage cylinder 13 and the nozzle 13a in FIG. 1). The image is read by the image recognition camera 15 and stored in a RAM built in the microcomputer 17a (FIG. 3) and an external storage device such as the hard disk 18a or the floppy disk 18b in FIG. That is, here, the data necessary for the paste pattern application drawing performed in step 600 of FIG.
It is converted into a predetermined format and stored in the RAM or an external storage device.

As another method, the contents of the coating drawing condition DA can be simplified. The method is shown in FIG. 7 and FIG.
Will be explained. FIG. 7 is a diagram showing a simplified coating and drawing condition DA recorded on the substrate for coating and drawing the paste pattern, and FIG. 8 is such a coating and drawing condition D.
FIG. 6 is an enlarged view showing a specific example of a paste pattern PP1 applied and drawn based on A.

Even in this case, on the surface of the substrate 9,
As shown in FIG. 5, the coating drawing condition DA is recorded, but the coating drawing condition DA is simplified.

In this method, as shown in FIG. 8, shape information (positional information) for each paste pattern is formed with a unique mark at a position on the substrate where coating and drawing are actually performed. This is recognized by the image recognition camera 15 (FIG. 1) attached to the head unit and stored in the RAM or the external storage device. The coating drawing condition DA thus obtained is shown in FIG. 7, and the paste pattern shape information (shape data) PD4 is omitted from the coating drawing condition DA shown in FIG. There is. Here, in FIG. 8, the application start position of the paste pattern is represented by a ▼ mark SP, the application end position is represented by a ▲ mark EP, and intermediate positions in the middle are recorded and formed by Δ marks CP1 to CP6. The ▼ mark and the Δ mark indicate the pattern forming direction by the direction thereof.

As described above, since the shape of the paste pattern to be applied and drawn is represented by the mark at the position where the paste pattern is actually applied and drawn, the shape information (shape data) PD4 of the paste pattern is unnecessary. Therefore, the storage area of the read data in the RAM or the external storage device can be reduced accordingly.

In this way, the data input by the operator for each product type can be automatically read, and a mistake in the data input operation from the keyboard 20 (FIG. 1) that is usually performed in the paste pattern application drawing operation. Will be eliminated and productivity will be further improved.
In addition, it is possible to check for errors in the loaded board.

In FIG. 4, when the process of step 400 is completed as described above, a substrate preliminary positioning process (step 500) is next performed. In this process, the positioning mark of the substrate 9 mounted on the substrate holding mechanism 7 is photographed by the image recognition camera 15, and the position of the center of gravity of the positioning mark is obtained by image processing in the θ axis direction of the substrate 9. Is detected, and the servo motor 8a (FIG. 3) is driven accordingly,
This inclination in the θ-axis direction is also corrected.

When the paste remaining in the paste storage cylinder 13 is small, it is necessary to prevent the paste from being interrupted during the next paste application operation. For this reason, the paste storage cylinder 13 may be replaced with the nozzle 13a in advance. When the nozzle 13a is replaced, the nozzle 13a may be displaced. For this reason, the nozzle is replaced at a position on the substrate 9 where the paste pattern is not formed, and a cross pattern is drawn on the substrate at that position using the replaced new nozzle 13a. Then, the cross pattern is picked up by the recognition camera 15 and the barycentric position of the intersection is obtained by image processing, and the distance between the barycentric position and the barycentric position of the positioning mark on the substrate 9 is calculated. The calculated distance is corrected by the moving distance required for replacement, and the corrected distance is stored in the RAM built in the microcomputer 17a as the positional deviation amounts dx and dy of the paste ejection port of the nozzle 13a.

With the above, the substrate preliminary positioning process (step 500) is completed. The positional deviation amounts dx and dy of the nozzle 13a are used for correcting the positional deviation of the nozzle 13a during the operation of applying and drawing the paste pattern to be performed later.

Next, a paste pattern drawing process (step 600) is performed.

In this process, the nozzle 13 is placed at the coating start position.
In order to position the paste discharge port of a, the substrate 9 is moved and the nozzle positions are compared and adjusted.

For this purpose, the microcomputer 17a is first subjected to the substrate preliminary positioning process (step 500).
Displacement amount d of the nozzle 13a stored in the RAM of
It is determined whether x and dy are within the permissible ranges ΔX and ΔY of the positional deviation amount of the nozzle 13a shown in FIG. If it is within the allowable range (ΔX ≧ dx and ΔY ≧ dy), it is left as it is, but outside the allowable range (ΔX <dx or ΔY <d.
If y), the substrate 9 is moved based on the positional deviation amounts dx, dy so that the positional deviation amounts dx, dy fall within the allowable ranges ΔX, ΔY. As a result, the displacement between the paste discharge port of the nozzle 13a and the desired position of the substrate 9 is eliminated, and the nozzle 13a is positioned at the desired position.

Next, the height of the nozzle 13a is set to the paste pattern drawing height. The nozzle 13a is lowered by the initial moving distance based on the initial moving distance data of the nozzle. Subsequently, the height of the nozzle 13a is measured by the distance meter 16 and it is confirmed whether or not the tip (paste ejection port) of the nozzle 13a is set to a height for drawing a paste pattern. As a result, when the drawing height cannot be set, the nozzle 13a is moved down a minute distance,
The measurement of the height of the nozzle 13a and the lowering of the minute distance are repeated, and the tip of the nozzle 13a is set to the height at which the paste pattern is applied and drawn.

If the paste storage cylinder 13 is not replaced, there is no data of the positional deviation amounts dx and dy of the nozzle 13a, so the paste pattern drawing process (step 6).
00), immediately after the above nozzle 13a
Set the height of.

When the above processing is completed, the servo motors 4 and 6 are driven based on the paste pattern data stored in the RAM built in the microcomputer 17a. As a result, with the paste discharge port of the nozzle 13a facing the substrate 28, the substrate 9 moves in the X and Y axis directions according to the paste pattern data. At the same time, the positive pressure source 25 to the valve unit 24 shown in FIG.
A slight atmospheric pressure is applied to the paste storage cylinder 13 via
As a result, the paste starts to be discharged from the paste discharge port of the nozzle 13a. As a result, the paste pattern coating and drawing on the substrate 9 is started.

Then, as described above, data obtained by actually measuring the height of the nozzle 13a (that is, the distance between the paste discharge port and the surface of the substrate 9) using the distance meter 16 is sequentially input to the microcomputer 17a. To be done. The microcomputer 17a obtains the waviness of the surface of the substrate 9 from the input actual measurement data, and the microcomputer 17a
Using the obtained value, the height of the nozzle 13a is maintained at a prescribed constant height regardless of this undulation,
The servo motor 12 is driven.

In this way, the drawing of the paste pattern proceeds. Then, it is determined whether or not the paste discharge port of the nozzle 13a is the end of the drawing pattern determined by the paste pattern data on the substrate 9. If it is not the end, the process returns to the surface waviness measurement process of the substrate 9
Hereinafter, the above-mentioned coating and drawing are repeated until the formation of the paste pattern reaches the end of the drawing pattern.

When the end of the drawing pattern is reached, the pressurization from the positive pressure source 25 to the paste accommodating cylinder 13 is stopped and the negative pressure from the negative pressure source 24 is accommodated in the paste through the regulator 24a and the valve unit 26. It is applied to the cylinder 13. As a result, the paste in the vicinity of the paste discharge port of the nozzle 13a is pulled back into the paste storage cylinder 13. afterwards,
The valve unit 26 is operated to stop the negative pressure, and the atmosphere 27 is applied to the paste storage cylinder 13. Further, the servo motor 12 is driven to raise the nozzle 13a, and the paste pattern drawing step (step 600) is completed.

Next, in the substrate discharging step (step 700), the holding of the substrate 9 in FIG. 1 is released, and the substrate 9 is discharged outside the apparatus. Then, it is determined whether or not there is another substrate to be applied (step 800), and if there is a substrate on which the paste pattern is formed with the same pattern, step 300 is performed.
When there is no substrate to be processed, the work is completed (step 900).

As described above, in this embodiment, the coating and drawing conditions and the like are recorded in advance on the substrate to which the paste pattern is to be applied. Therefore, even if a substrate having different specifications is loaded in the middle, an error is automatically made. It is possible to detect and to prevent an input error by the operator.

[0057]

As described above, according to the present invention,
It is possible to automate the operation of inputting the coating and drawing conditions of the paste pattern, which is performed as one of the setup change operations by the operator, prevent the operator's operation mistake, and improve the productivity.
