BACKGROUND OF THE INVENTION

[0002]
[Prior art]
As this kind of coating device, one described in Japanese Patent Laid-Open No. 6-169159 is known. According to this prior art, the adhesive as an application agent stored in the syringe is applied to a predetermined position on the printed circuit board by applying compressed air to the syringe for a predetermined time. Since the amount of the coating agent is different, the coating amount is controlled. The control is performed by controlling the air pressure of the compressed air and the discharge time, which is the time during which the air is applied.
[0003]
The application conditions of the air pressure and the discharge time are stored as application condition data, and each application condition data corresponds to a predetermined target amount to be applied. According to this application condition data, the application amount of the set target amount is to be applied for each application operation. When the remaining amount of adhesive in the syringe changes, the application condition data set at the beginning is used. It is necessary to correct the discharge time of the application condition data because the application amount cannot be obtained even if the application is performed. Therefore, apart from the application operation for production, the adhesive is applied under predetermined application conditions, the amount thereof is recognized and detected by the camera, and the discharge time to be corrected so as to be the target amount is calculated.
[0004]
In this case, it is conceivable to calculate the discharge time correction time by applying and recognizing the adhesive on the detection plate (recognition plate) that is the application target surface for each application condition.
In some cases, the detection plate is thrown away, that is, when the nozzle is not used for a long time, for example, a coating for stabilizing the next coating is performed.
When these coatings are performed, these coatings are sequentially performed next to each other on the detection plate, but the coating pitch is always applied at the same pitch according to the maximum nozzle.
[0005]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
In FIG. 2, reference numeral 1 denotes a printed circuit board, which is placed on an XY table 4 as relative movement means that moves in the XY directions by driving the X-axis motor 2 and the Y-axis motor 3. Reference numeral 5 denotes an application unit, which applies an adhesive as an application agent stored in the syringe 7 onto the substrate 1 through an application nozzle 6 attached to the syringe 7. The coating unit 5 includes four syringes 7 to which nozzles 6 are attached. The nozzle 6 to be used is selected from the nozzles 6 and is moved up and down by a nozzle up-and-down mechanism (not shown), and the tip of the nozzle 6 is placed on the substrate 1. The discharged adhesive is applied.
[0017]
As shown in FIG. 6, two coating nozzles 6 are formed on a nozzle holding body 9 that is connected to the inside of the syringe 7, and a stopper pin 10 is erected on a straight line that is orthogonal to a straight line that connects the nozzles 6. ing. The stopper pin 10 is formed to be slightly longer than the nozzle 6. When the syringe 7 is lowered, the stopper pin 10 abuts on the substrate 1 and the nozzle 6 does not directly abut on the substrate 1. A predetermined space is formed between them.
[0018]
An air passage 30 to be described later communicates with the compressed air source from the upper end of the syringe 7, and a regulator to be described later is provided for each syringe 7 to set the pressure of air to be applied to each syringe 7 in the middle thereof. 26 and a discharge valve 27, which will be described later, for switching whether compressed air is added to the syringe 7 or opened to the atmosphere are provided. The printed circuit board 1 is fed onto the XY table 4 by the supply conveyor 11, and the substrate 1 on the XY table 4 is discharged and conveyed to a downstream apparatus by the discharge conveyor 12. As shown in FIG. 3, a fixed chute 13 and a movable chute 14 are provided on the XY table 4 to deliver the substrate 1 from the supply conveyor 11, and the substrate 1 is positioned and fixed on the chutes 13 and 14 and bonded. The agent is applied. A recognition plate 16 is attached to the movable chute 14, and application for discarding the adhesive and application for recognizing the application amount are performed. The application for throwing away is the application of the adhesive on the recognition plate 16 before the application of the adhesive on the substrate 1 using the nozzle 6 that has not been used for a long time. If the application operation to the substrate 1 is performed with the adhesive hanging from the nozzle 6, the application amount of the adhesive changes, and this is done to prevent this. When the application for recognizing the application amount is performed on the recognition plate 16, the recognition camera 8 provided in the application unit 5 recognizes the applied adhesive, and the application diameter is recognized. Since the adhesive is applied in a substantially circular shape, the application amount of the adhesive is recognized by recognizing the application diameter. The application surface of the recognition plate 16 becomes the application target surface.
[0019]
The application nozzles 6 attached to the syringes 7 are provided with different types such as different discharge port diameters, and are used properly at the time of application to the substrate 1 due to differences in the discharge amount.
Although the fixed chute 13 is fixed, the movable chute 14 moves so as to be able to come into contact with and separate from the fixed chute 14 so that the width direction orthogonal to the transport direction of the substrate 1 can be changed depending on the substrate type. Since the recognition plate 16 is attached to the movable chute 14, the recognition plate 16 also moves as the movable chute 14 moves. In this embodiment, the recognition plate 16 is provided separately from the substrate 1 so that the application for discarding and the application for recognizing the application amount are performed. You may make it apply | coat an adhesive agent to this place.
[0020]
Next, a control block diagram of the coating apparatus will be described based on FIG.
Reference numeral 20 denotes a CPU serving as a determination unit and a control unit, which comprehensively controls various operations related to the coating operation of the coating apparatus in accordance with a control program stored in the ROM 22 based on various data stored in the RAM 21. The bus line 23 connected to the CPU 20 is connected to the X-axis motor 2, the Y-axis motor 3, the recognition camera 8, the regulator 26, and the discharge valve 27 via the interface 24. The interface 24 is also connected to a CRT 28 that displays various screens. An air passage 30 that is a passage for compressed air communicates from the regulator 26 and the discharge valve 27 into the syringe. In FIG. 4, the regulator 26 and the discharge valve 27 are shown one by one, but are provided for each syringe 7, and the number of syringes 7 is provided.
[0021]
The NC data is created for each board type, and the data in FIG. 5 corresponds to the board type “AAA”. The NC data is composed of operation data composed of data such as the substrate size (XY direction size and thickness size), coating step data, and coating condition data. The application device applies an amount of adhesive to be applied to a position to be applied in accordance with data supported by the step for each step of the application step data. The application data name shown in the step is application condition data. The number assigned to each coating condition is selected, and each data indicating the coating condition corresponding to the coating condition data is selected from the coating data name. The application conditions include the nozzle ID of the nozzle 6 (which indicates whether the nozzle 6 is located at any one of the four nozzles 6, and the number of ejection holes, the height of the stoppers and ejection holes is determined by other data not shown) Nozzle type such as a gap is understood.), Discharge time (time for applying air pressure to the syringe 7), discharge pressure indicating the air pressure to be applied to the syringe 7, and application amount data indicating the target application amount to be applied And data such as a gauge (a number indicating the regulator 26 provided for each syringe 7) is stored.
[0022]
As shown in FIG. 7, the recognition plate 16 is divided into areas 1 and 2. The application for discarding is performed in area 1, and the application for recognizing the application amount is performed in area 2. Is called. The RAM 21 stores the position of each area. This position may be stored in the ROM 22.
In addition, the application area is set for each application nozzle 6 mounted on the syringe 7 and stored in the RAM 21 or the ROM 22.
[0023]
The application area is set for each type of nozzle 6 for the disposal application and the application for recognizing the application amount. The example in FIG. 8 is set as the application for disposal, and the one in FIG. It is an example set to application for application amount recognition.
In this application area, the stopper pin 10 does not hit the already applied adhesive even with the maximum possible application diameter to which the adhesive is applied from the nozzle 6 in the disposal application, and the adhesive to be applied next is not applied. Considering not to overlap, the application area set in this way is set to a range that satisfies the conditions of the stopper pin 10 and the like if the application area does not overlap with the application areas of other application points.
[0024]
In addition, in the application for coating amount recognition, in addition to the above-described conditions for application for throwing away, it is necessary to prevent the coating agent at other application points from entering the visual field of the recognition process when recognizing the applied coating agent. This is a condition that takes into account the occurrence of stringing of the adhesive, and has a wider application area than the application for throwing away. In the thread drawing, when the adhesive discharged from the nozzle 6 adheres to the surface to be applied and the nozzle 6 moves up, the stretched portion is pulled from the nozzle 6 without being separated from the nozzle 6 and finally cut from the nozzle 6. It means the part that sticks out like a whisker than the adhesive applied in a circle when it falls down, and assuming this part, the application area must be enlarged in the same way as when the application diameter is large Is. Also, the application area varies depending on the type of adhesive.
[0025]
In the present embodiment, this region is set to a rectangular shape having sides in a direction parallel to and perpendicular to the straight line where the nozzles 6 are arranged. That is, two values in the X direction and the Y direction shown in FIG. 7 are set. The reference position of the nozzle 6 is the center position of this application region.
This application region is not uniformly determined, and varies depending on the person who sets the margin according to how much margin is viewed. However, by setting the recognition plate 16 to be as small as possible, the recognition plate 16 can be used. It can be used densely and efficiently. In addition, since the setting of the application area changes according to the maximum application amount for each nozzle 6, the smaller the discharge diameter of the nozzle, the smaller the application of the nozzle with a smaller discharge diameter. It will be set to the area.
[0026]
In this embodiment, one region is determined for each type of nozzle 6, but the region may be set and stored for each application amount. If it is determined for each coating amount, it is preferable to determine based on the coating amount that is the target of the coating condition data.
Further, the application point that is the position where the coating agent is applied in each of the areas 1 and 2, that is, the position where the reference position of the nozzle 6 is positioned in the recognition plate 16 by the movement of the XY table 4 is stored in the RAM 21. In this area, the position of the last application point can be seen. In this embodiment, the reference position of the nozzle 6 is the position of the midpoint between the two nozzles 6 formed on the nozzle holder 9.
[0027]
In addition, the position of the first start point, which is the position of the first application point to be applied in each area, and the second start point, which is the first application point when the other area is full, are entered. It is stored in the RAM 21 or ROM 22.
The ROM 22 also stores a program for controlling the operation of the flowchart as shown in FIG.
[0028]
Next, the production operation operation of the coating apparatus will be described.
The CPU 20 reads the application step of the application step data of the NC data, and reads the data of each application condition corresponding to the application condition data from the application data name of the step.
Next, the XY table 4 is moved to the position indicated by the designated position data, the nozzle 6 of the designated nozzle ID is lowered, the regulator 26 is set to the value indicated by the data, and the discharge valve 27 is opened for the data time. The adhesive is discharged for a specified discharge time. In this way, the adhesive is applied to the designated position on the substrate 1. That is, if it is step M001, the valve 27 is switched to the compressed air side at a predetermined timing for the nozzle 6 with the nozzle ID “1110” at the pressure P1 and the discharge time is 5 msec, and the compressed air is added into the syringe 7.
[0029]
In this way, the adhesive is applied for each step of the application step data.
In this way, when one substrate 1 is completed, the number of substrates is counted, and the substrate 1 is discharged and conveyed by the discharge conveyor 12.
A chip-shaped electronic component is mounted on the discharged substrate 1 at a position where the adhesive is applied, and the component is temporarily fixed to the substrate 1 with the adhesive.
[0030]
In this way, for example, when the number of substrates reaches the operating condition for coating amount recognition, the CPU 20 determines that the operating condition for checking the coating amount has been reached, and the coating amount checking operation is performed for this nozzle 6.
At this time, if it is set to perform the discarding application prior to the application amount recognition, the CPU 20 determines the operating condition for the discarding application and discards it in the area 1 of the recognition plate 16 as shown in FIG. Control the application of the.
[0031]
That is, the position of the final application point in area 1 is read from the RAM 21. If it has not been applied yet, it is stored that there is no application point, the CPU 20 as the determining means determines to apply at the position of the first start point, and further the CPU 20 moves relative as the control means. The XY table 4 as a means is controlled to move the reference position of the nozzle 6 so as to coincide with the first start point, and an adhesive is applied for disposal application.
[0032]
In this case, the nozzle 6 and the syringe 7 (not shown) are rotated in a direction in which the nozzles 6 are arranged in the Y direction of FIG. Apply the agent.
If the application for discarding is set twice, the application for discarding is performed one more time, but the second time, the value of the application area in the X direction of the nozzle 6 that applied the first start point is set. A value obtained by adding 1/2 of the value of the application region in the X direction of the nozzle 6 this time to 1/2 is determined as the movement pitch (that is, in this case, the types of both nozzles 6 are the same, The application area is the same.), The nozzle 6 is moved in the X direction by the determined application area, the nozzle 6 is lowered, and the application is discarded. In this way, the minimum distance set for the nozzle 6 is moved and applied, and the loss of the area of the recognition plate 16 can be suppressed.
[0033]
Next, since the application for discarding has been completed, the CPU 20 determines that the condition for application for recognizing the application amount has been reached, and controls to perform application for recognizing the application amount.
That is, the position of the final recognition application point stored in the RAM 21 is read out in the same manner as the application for discarding, and the application area data corresponding to the type of the nozzle 6 at this time is read out. By adding 1/2 of the value of the application area in the current X direction to 1/2 of the value of the area, the pitch to be moved is set, and the reference position of the nozzle 6 is moved in the X direction from the position of the previous application point by this value. The XY table 4 is moved so that it does not move in the Y direction.
[0034]
Next, the CPU 20 reads the application condition for the nozzle 6 that has become the operation condition from the application condition data, controls the regulator 26 based on these conditions, discharges the adhesive, opens the discharge valve 27, and meets it. Adhesive is discharged in a predetermined amount, and is applied to the position to be applied next to the area 2 of the recognition plate 16 by lowering the nozzle 6.
[0035]
In this way, when the application for recognition is performed for each application condition with respect to the same nozzle 6, each application point is moved by the movement of the XY table 4 so as to sequentially enter the field of view of the camera 8.
In this way, the application amount at each application point is recognized. These recognition results are stored in a predetermined area of the RAM 21 so that it can be identified which application data name, and the application condition data is corrected based on these data.
[0036]
In order to confirm whether or not an accurate application amount can be obtained under the corrected application conditions, application for recognizing the application amount may be performed again. It is applied to the area 2 at a position to be applied next to the previous application point.
Even in the case of throwing away application or application for application amount recognition, the X direction is applied as the traveling direction, but when determining the next application point, an attempt was made to apply to the application point calculated in the same manner as described above. In the case where the application area is out of the area 1 or area 2 (calculation is possible from the area range stored in the RAM 21 or the like), it is determined that the application point cannot be applied, Judgment to be rearranged.
[0037]
That is, a new column is set at a position shifted in parallel from the column of the previous traveling direction, and the application points are arranged with the direction of this column as the traveling direction. First, how far the column is set in the Y direction is set. calculate.
The amount of shift in the Y direction is obtained by adding 1/2 of the application area in the Y direction of the nozzle 6 to be applied next to 1/2 of the application area in the Y direction of the application point at the head position in the row so far. The leading position in the X direction of the position shifted in the Y direction by this amount is determined as the position of the application point to be applied next.
[0038]
The X direction position of this position is preferably set as the same position as the previous application point, and in this way, the amount of movement of the XY table 4 is small when continuously applied as shown in FIG. I'll do it. Alternatively, the position in the X direction can always be the same as the position of the first start point, and the zigzag can be advanced.
In addition, since the position in the Y direction is not changed in the same row, if the coating is performed with the nozzle 6 having a coating region whose Y direction is larger than the coating region of the first coating point in the row, the coating has already been performed. Since there is a possibility of overlapping with the adhesive at the adjacent application point, the rearrangement is performed even if there is still a space in which the point can be applied in the X direction. At this time, the position of the next row in the X direction may be the position of the first start point, or the position of the opposite end and the position of the first start point closer to the X direction position should be selected. May be.
[0039]
In addition, when an application region having a large Y direction occurs on the way, the position of the subsequent application point is shifted by shifting the position in the Y direction from the application point so as not to overlap with the already applied application point row. In the next rearrangement, the Y position of the next row may be calculated and determined based on the Y direction position of the final application point.
Further, when the adhesive is applied in each of the area 1 and the area 2, one of the areas is filled first, and there is no place to apply any more, but in this case, the area is still full. What is necessary is just to make the position of the 2nd start point of the area which does not exist into the next application | coating point. The direction in which the subsequent Y direction deviates, that is, the direction of rearrangement, is directed in the opposite direction.
[0040]
When all the recognition plates 16 are finally full, when an application point to be applied next occurs, it is only necessary to notify the operator that it is full without applying it. . The operator may remove the recognition plate 16 from its mounting position to make a new one, or the application surface of the recognition plate 16 may be blown off using a solvent or the like. What is necessary is just to reset the data of the applied application point.
[0041]
In this embodiment, the area is divided into two areas, and it is possible to distinguish whether the application point applied by looking at the operator is a throw-off or application amount recognition, and various determinations can be made. It is also possible to mix the application for recognizing throwing and the application for recognizing the coating amount without dividing them, and in this case, even if the application points before and after are for throwing and recognizing the application amount, each application point is applied. The area value can be processed in the same manner as described above to determine the position of the next application point.
[0042]
Further, in the present embodiment, the recognition plate 16 is used as the application target surface. However, even when an empty space other than the position where the adhesive is applied by the NC data of the substrate 1 is used as the application target surface, the empty space is stored. In addition, the space can be used without waste by performing the control as in the present embodiment.
In this embodiment, the application target surface has a spread in the X and Y directions and is applied by rearranging to change the traveling direction. However, it is applied to a linear object such as a tape and proceeds only in one direction. Even if it does not work (this tape will be wound up), set the application area only in the direction of travel and control the distance to the next application point in the same way, etc. In this case, if the syringe is equipped with a plurality of nozzles on a straight line, the direction of the nozzle should be set so that the direction of the straight line is orthogonal to the traveling direction. By rotating and positioning the coating, the coating area can be set small, and the space can be used effectively.
[0043]
【The invention's effect】
As described above, according to the present invention, the distance between the application points of the coating agent can be optimized according to the type of the nozzle. Therefore, the application can be effectively used without wasting the area of the application target surface. Can be made.
In addition, since the distance between the application points of the coating agent can be optimized according to the coating amount of the coating agent, it is possible to apply without wasting the area of the application target surface.
[0044]
In addition, the pitch of the application points applied for each application operation can be narrowed at the time of discarding or application amount recognition, so that the area of the application target surface can be prevented from being wasted.
Further, the surface to be coated is divided into two areas for throwing-out coating and coating for recognizing the coating amount, and when one of the areas becomes full, another area is filled with the next area. Since the application point is applied, one area is not filled and the space in the other area is not wasted, and the space on the application target surface can be effectively used as a whole.
