Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive applying device for applying an adhesive for temporarily fixing electronic parts to a predetermined portion such as a printed circuit board.

[0002]

2. Description of the Related Art In order to mount an electronic component on a printed circuit board or the like, it is necessary to prepare data on the application position of an adhesive. Regarding creation of coating position data, the NC program is configured to have data for coating positioning,
The component library is configured to have data specific to each component such as head speed, coating nozzle, coating amount, coating frequency, coating pitch, coating direction, but in recent years electronic components have become larger, finer, and diversified. And with it,
Adhesive coating patterns are also diversifying according to the shape of parts.

The conventional creation of coating position data will be described below. FIG. 5 shows an NC program format 1 as a conventional coating position, in which an X, Y coordinate 2 as a coating position and a coating rotation angle 3 are input to generate an NC program.

FIG. 6 shows a component library 4, which is formed by inputting a head speed 5, a coating nozzle selection 6, a coating amount 7, a coating frequency 8, a coating pitch 9 and a coating direction 10. It was

[0005]

However, in the conventional operation of creating the application position data, the position data for applying the adhesive is created by the operator and must be created according to the shape and size of the electronic component. Head speed for each electronic component, coating nozzle, coating amount, coating frequency,
Since it is necessary for the operator to determine the coating pitch and the coating direction, it takes a lot of time and effort to create the coating position data.

Further, QF having a large number of coating points per part
For large parts such as P or special parts, it is restricted to freely create application information in the parts library, and the NC program newly creates the missing application position data for each electronic work. Since the components were adhered each time, work mistakes were likely to occur and the reliability was lowered.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an adhesive coating device which can create coating position data without much trouble.

[0008]

In order to solve the above-mentioned problems, the adhesive applying device of the present invention is provided with parts of a parts library .
Based on the component length and component thickness data of
Head speed and nozzle type that were initially set as appropriate values
Separately, a means for generating data on the coating amount, the coating frequency, the coating pitch, and the coating direction is provided , and the coating direction is the component length data.
The coating frequency and coating pitch are determined by
Determined by the length of the electronic component with respect to the applied direction,
The coating amount and coating nozzle type are the component length and component thickness data.
The head speed is determined according to the
It is determined from the data of the coating amount and the coating amount .

Also, for large parts having a large number of coating points,
Can set items for special multi-point dispensing in the parts library.
With, the relative value data of the dispensing point is set and
The number of times of application and application from the center position data of the part specified in
Pitch data is generated .

[0010]

With the above configuration, by inputting the data of the part length and the part thickness to the part library, the head speed, the nozzle type , the application amount, the number of times of application can be set from the conditions which are preset as appropriate values in the internal memory in advance. The coating pitch and coating direction are newly created as data without much trouble.

Further, QF having a large number of coating points per part
For large parts or special parts, such as P, by data set in the item of special multi-point application on the part library, can be created without taking the trouble the data of the application number, the application pitch.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. When the adhesive is applied to the chip type electronic component 11 as shown in FIG. 1, first, data of the component length 12 and the component thickness 13 is input to the component library 4 shown in FIG. Thereby, each data of the head speed 5, the coating nozzle selection 6, the coating amount 7, the coating number 8, the coating pitch 9, and the coating direction 10 is created from the information which is initially set as the appropriate value in the internal memory of the adhesive coating device. It is configured to be.

First, the coating direction 10 is component length data (component length upper, component length lower, component length left, component length right) 12
In this case, since [part length upper] ≧ [part length left], it is set to apply in the Y direction, and the applying direction 10 is set to 1 (Y direction).

The number of times of coating 8 is determined by the length of the electronic component 11 with respect to the coating direction calculated from the data of the component length 12. In this case, the number of actual coatings is 2 and the number of actual coatings = the number of coatings + 1 is set. Therefore, the number of application times 8 is set to 1.

The coating pitch 9 is determined by the length of the electronic component 11 with respect to the coating direction. In this case, it is calculated from the component length left data, and the coating pitch 9 is set to 1.6. A value corresponding to the size of the electronic component is determined from the data of the component length 12 and the component thickness 13 as the application amount 7, and in this case, the magnification with respect to the reference application amount is determined, and 1 is set as data.

For the coating nozzle selection 6, a value corresponding to the size of the electronic component is determined from the data of the component length 12 and the component thickness 13. In this case, 1 as the small nozzle is set as the data of the coating nozzle selection 6. It

The head speed 5 is determined from the data of the coating nozzle and the coating amount. In this case, the head speed 5 is set to 1, which is the maximum speed. Data of the head speed 5, the coating nozzle selection 6, the coating amount 7, the coating number 8, the coating pitch 9, and the coating direction 10 are created without the trouble as described above, and the actual coating shown in FIG. Applied in position.

Next, another embodiment of the present invention will be described with reference to FIGS. Large QF as in Figure 2
When applying to the electronic component 20 made of P, if 1 (1: valid, 0 invalid) is set in the item of the special multi-point coating 21 in the component library 22 of FIG. 3, the data of the component library 23 shown in FIG. The setting screen is displayed. The center of the electronic component 20 in FIG. 2 is the NC program coordinate, and N
o. In the data setting of 1 to 10, each is set as relative value data from the NC program coordinates. Position data of a plurality of application points can be created from this relative value data without trouble, and a parts library that does not depend on the NC program can be created. As shown in FIG. 2, application is performed at a plurality of application points. .

[0019]

As described above, according to the present invention, when a new component library is created, by inputting data of the component length and the component thickness into the component library, the head speed, the nozzle type , and the coating amount can be obtained. Since the number of coatings, coating pitch, coating direction are newly created as data,
The application positioning information can be created without trouble.
