Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to an adhesive coating device for applying adhesive or the like.

2. Description of the Related Art A conventional adhesive applicator of this type has a structure as shown in FIG. That is, the printed board is fed into the XY table by the board loading section 1 which is movable up and down. Two dispensers 4a and 4b having two cylindrical arms 3ρ and capable of vertically sliding are attached to the adhesive application section. As shown in FIG. 3a, the dispenser 4at/C is equipped with two nozzles with small diameter pipes for discharging a small amount of M detergent 6a in order to mount the small parts 6, and the dispenser 4b is equipped with a third nozzle. As shown in the figure, two nozzles with large diameters for discharging a large amount of adhesive are attached to attach a large component 7, and a dispenser can be selected according to the size and shape of the chip component. Arm 3
is rotated by a driving cylinder 8, and the two dispensers +a and 4b move along the groove 9a of the grate 9. The XY table 2 brings the printed circuit board to a predetermined position directly below the dispenser located in the center of the plate 9, and the dispenser descends until the nozzle 10 touches the printed circuit board, discharging the adhesive h from the nozzle 1o. The printed circuit board on which the adhesive has been applied is conveyed out of the adhesive coating apparatus by a vertically movable substrate unloading section 11.

Problems to be Solved by the Invention However, in the above configuration, the XY table also moves in a direction parallel to the flow of printed circuit boards, so the rails for loading and unloading printed circuit boards into the XY table avoid interference with the XY table. Therefore, it is necessary to have a dedicated board loading section and a board unloading section which have a drive for moving the entire rail up and down, which poses a problem in that the overall size of the adhesive coating device becomes very large.

Furthermore, it has become necessary to provide a dedicated dispenser for microchip components, which have been on the rise in recent years.

However, in the above configuration, if the number of dispensers to be attached to the arm is increased, it is impossible to select the dispenser using a driving cylinder, so a motor or the like is required as a drive source to rotate the arm. It becomes. Therefore, the adhesive application section has become large and mechanically complex, which has been a problem.

In view of the above-mentioned problems, the present invention eliminates the need for a dedicated board loading section and board unloading section, significantly reduces the overall size, and does not increase the size of the adhesive application section even if the dispenser increases several times. The present invention provides an adhesive application device that is mechanically simple.

Means for Solving the Problems In order to solve all of the above problems, the adhesive applicator of the present invention has a table part which is provided to be able to hold a printed circuit board and is movable in one direction, and a table part which is provided to be able to hold a printed circuit board and which is movable in one direction. It consists of an adhesive applicator that has a plurality of vertically aligned dispensers and is movable in a direction perpendicular to the movement direction of the table, and a control unit that moves the table to a predetermined position, selects a predetermined dispenser, and applies adhesive. composition? It is prepared.

Effect The effect of the above means is as follows. In other words, since the table only moves in the direction perpendicular to the flow of substrates, there is no need to provide a substrate loading section and a substrate loading section that can move up and down to avoid interference with the table, which greatly reduces the overall size of the adhesive applicator. It is possible to make it as small as possible.

In addition, since the adhesive application section has a plurality of dispensers arranged in a row and does not require a drive source for selecting the dispensers, it is possible to completely prevent an increase in size and also to simplify the mechanism.

EXAMPLE Hereinafter, an adhesive coating apparatus according to an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of an adhesive applicator according to an embodiment of the present invention. In FIG. 1, 12 is a dispenser guide, and three dispensers 13a are vertically slidable on this dispenser guide.

13b and 13c are attached. The dispenser guide 12 is slidably attached to the body 14, and the entire driving force for the dispenser guide 12 is driven by a ball screw 16.
is attached to the body 14 via a bearing 16. Rotating shaft pulley 17 fixed to ball screw 16
is connected to the gear 7-19 fixed to the pulse motor 18 by a belt 2o. The table 21 is the body 14
The pole screw 230 rotary shaft 924 is slidably attached to the guide 22 fixed to the table, and the rotation shaft 924 of the pole screw 230 receives all the sliding power of the table.
and are connected by a belt 27. board transport rail 28a,
28b is not attached to the adhesive applicator, but is used to transport the printed circuit board to a position where it can be loaded onto the table 21 of this apparatus.

Next, the operation of the configuration of this embodiment will be explained. When the table 21 has moved to a position where the board can be loaded, the printed circuit board is moved to the table 21 by the board transport rail 28a.
is carried onto the top surface of the Three dispensers 13a, 13
b and j3c are dispensers for large parts, small parts, and micro parts, respectively, and the nozzle shapes are different, and the dispenser can be selected depending on the shape of the chip part to be mounted.

The dispenser guide 12 is driven by a ball screw 15 rotated by a pulse motor 18, and the dispenser is selected by moving the dispenser to be used onto a predetermined position of the substrate in a direction parallel to the substrate flow. At the same time, the table 21 is moved in a direction perpendicular to the flow of the substrate by a ball screw 23 rotated by a pulse motor 26 to move a predetermined position of the substrate under the alignment line of all dispensers.

After the predetermined position of the substrate has been moved directly below the selected dispenser, the dispenser is lowered until the tip of the nozzle 29 contacts the substrate and the adhesive is discharged from the nozzle 29. Once the table 21 has moved to a position where the board can be unloaded, the printed circuit board that has been coated with adhesive is transferred to the board transport rail 28b.
It is carried out from the top surface of the table 21 by.

As a result, the table 21 moves only in the direction perpendicular to the substrate flow, so the substrate loading section, which can move up and down as in the conventional case,
A substrate carrying-out section is no longer required, and the size of the entire adhesive application device can be significantly reduced.

Dispenser selection is done by moving the adhesive application part parallel to the substrate flow, so it is difficult to select a dispenser. It is not necessary to mount a drive source in all adhesive application parts, which simplifies the mechanism.

In addition to the effects of the invention, the present invention provides the above-mentioned table that moves only in the direction perpendicular to the flow of the substrate. There is no need for the vertically movable substrate loading section and substrate loading section, and the size of the entire adhesive coating device can be significantly reduced.

Further, in the present invention, the dispenser selection is performed by moving the entire adhesive application device in which a plurality of dispensers are arranged in a direction parallel to the plate flow, so it is necessary to mount a drive source for dispenser selection in the adhesive application section. It becomes mechanically simpler.
