Description

The present invention relates to a coating device.

As a coating device, a device having a single dispenser and applying a coating agent to a substrate (that is, a member to be coated) with a dispenser is known. According to the coating apparatus, for example, when the coating agent is applied to a member to be coated in a plurality of rows, if the coating pitches (coating intervals) of the plurality of rows are different, a single coating pitch is matched to the coating pitches of the plurality of rows. By reciprocating the dispenser, it is possible to apply the coating agent to the member to be coated with the dispenser. According to this method, coating can be performed corresponding to various coating pitches only by moving the dispenser or the coating member in the coating pitch direction.

Japanese Unexamined Patent Publication No. 2005-236230

However, since the coating device of Patent Document 1 includes a single dispenser, it is necessary to reciprocate the dispenser according to the coating pitch of a plurality of rows, and it takes time to apply the coating agent.
As a countermeasure for this, for example, it is conceivable to provide a dispenser according to the coating pitch of a plurality of rows. However, if the dispenser is provided according to the coating pitch of a plurality of rows, a dispenser corresponding to the coating pitch is required. Further, in order to correspond to various coating pitches, it becomes necessary to provide an adjusting mechanism in the coating pitch direction of a plurality of dispensers. Therefore, it is conceivable that the coating device becomes large and the cost of the coating device increases.

Therefore, in view of the above circumstances, the present invention can apply the coating agent in correspondence with a plurality of rows of coating pitches, can cope with various coating pitches, and can be increased in size. An object of the present invention is to provide a coating device capable of reducing costs.

In order to solve the above problems, the coating device according to one aspect of the present invention is rotatably supported by a support member, and a plurality of dispensers capable of adjusting the coating amount of the coating agent are provided, and the support member is described. The first pitch adjusting mechanism that adjusts the coating pitch of the plurality of dispensers by rotating the plurality of dispensers, and the pitch between the plurality of dispensers by moving the plurality of dispensers linearly with respect to the support member. A second pitch adjusting mechanism for adjusting is provided , and the first pitch adjusting mechanism increases the coating pitch of the plurality of dispensers by rotating the plurality of dispensers in one direction with respect to the support member, and increases the coating pitch of the plurality of dispensers in the other. The application pitch of the plurality of dispensers is reduced by rotating the dispenser.

According to this configuration, the second pitch adjusting mechanism moves the plurality of dispensers in a straight line with respect to the support member to adjust the pitch between the plurality of dispensers. Therefore, the pitch between the plurality of dispensers can be adjusted individually. Further, by rotating the plurality of dispensers with respect to the support member by the first pitch adjusting mechanism, the coating pitches of the plurality of dispensers can be individually adjusted. As a result, the coating agent can be applied corresponding to an arbitrary coating pitch of the member to be coated.
Moreover, the coating pitch can be changed without increasing the number of dispensers. As a result, it is possible to suppress the increase in size of the coating device according to one aspect of the present invention, and further reduce the cost of the coating device.

Further, according to the coating apparatus of one aspect of the present invention, the coating agent can be efficiently applied to the member to be coated by individually adjusting the coating pitches of the plurality of dispensers. Therefore, it is possible to shorten the application time of the coating agent on the member to be coated.
Further, according to the coating device of one aspect of the present invention, the coating pitches of the plurality of dispensers can be individually adjusted, so that one coating device can handle members to be coated with various coating pitches.

According to this configuration, the pitch between dispensers is adjusted by the linear movement of the second pitch adjusting mechanism, and a plurality of dispensers are rotated by the first pitch adjusting mechanism, so that it can be obtained only by the linear motion mechanism by the second pitch adjusting mechanism. No pitch adjustment resolution can be obtained.

In the above aspect, at least one of the drive sources of the first pitch adjusting mechanism and the second pitch adjusting mechanism is an electric motor.
According to this configuration, for example, by using an electric motor as the drive source of the first pitch adjusting mechanism, a plurality of dispensers can be accurately rotated by the first pitch adjusting mechanism.
On the other hand, for example, by using an electric motor as the drive source of the second pitch adjusting mechanism, the pitch between a plurality of dispensers can be accurately adjusted by the second pitch adjusting mechanism.
As a result, the coating pitches of the plurality of dispensers can be individually and accurately adjusted.

In the above aspect, at least one of the first pitch adjusting mechanism and the second pitch adjusting mechanism is a two-position control mechanism.
According to this configuration, by using at least one of the first pitch adjusting mechanism and the second pitch adjusting mechanism as the two-position control mechanism, the movement of one pitch adjusting mechanism can be made quickly. As a result, the coating work by a plurality of dispensers can be speeded up.
Further, by using at least one of the first pitch adjusting mechanism and the second pitch adjusting mechanism as the two-position control mechanism, the cost of one pitch adjusting mechanism can be suppressed.
In the above aspect, the first pitch adjusting mechanism rotates the plurality of dispensers around the central dispenser among the plurality of dispensers.
According to this configuration, by rotating the plurality of dispensers around the central dispenser, the amount of adjustment of the coating pitches of the plurality of dispensers can be made uniform, so that the coating pitch can be easily managed.

In the above aspect, the coating agent is an adhesive.
According to this configuration, by using the coating agent as an adhesive, the adhesive can be applied in correspondence with the coating pitches of a plurality of rows.

According to one aspect of the present invention, the first pitch adjusting mechanism rotates a plurality of dispensers, and the second pitch adjusting mechanism moves the plurality of dispensers in a straight line. As a result, the coating agent can be applied in correspondence with the coating pitch of a plurality of rows, and the size and cost can be suppressed.

By rotating the first adjusting screw 56 with the first electric motor 55, the first slider 54 slides in the Y direction along the first support portion 45b.

A second dispenser 42 is attached to the first slider 54. The second dispenser 42 includes a second dispenser main body 57 attached to the first slider 54, and a second nozzle 58 provided on a surface 57a of the second dispenser main body 57 on the −Z direction side. The second nozzle 58 projects from the surface 57a of the second dispenser main body 57 in the −Z direction.
Therefore, by rotating the first adjusting screw 56 with the first electric motor 55, the second dispenser 42 (that is, the second nozzle 58) can be moved straight in the Y direction with respect to the connecting member 45.

That is, the second dispenser 42 can be moved straight in a direction intersecting the extension line (rotation center of the dispenser) of the support shaft 46a of the electric motor 46.
In the embodiment, an example in which the second dispenser 42 is moved straight in a direction orthogonal to the extension line of the support shaft 46a of the electric motor 46 will be described, but the present invention is not limited to this.
By using the first electric motor 55 for the first pitch adjusting unit 51, the second nozzle 58 of the second dispenser 42 can be moved straight to an arbitrary position.
The second dispenser 42 is configured so that the adhesive can be discharged from the tip of the second nozzle 58 and the amount of the adhesive discharged from the second nozzle 58 can be adjusted.

The second pitch adjusting unit 52 is configured in the same manner as the first pitch adjusting unit 51, and includes a second slider 61 and a second electric motor (drive source) 62.
The second slider 61 is movably connected to the second support portion 45c of the connecting member 45 in the Y direction. A second adjusting screw 59 (see FIG. 5) extending in the Y direction is screwed to the second slider 61. The output shaft of the second electric motor 62 is connected to the second adjusting screw 59.
By rotating the second adjusting screw 59 with the second electric motor 62, the second slider 61 slides in the Y direction.

A third dispenser 43 is attached to the second slider 61. The third dispenser 43 includes a third dispenser main body 63 attached to the second slider 61, and a third nozzle 64 provided on the surface 63a on the −Z direction side of the third dispenser main body 63. The third nozzle 64 projects from the surface 63a of the third dispenser main body 63 in the −Z direction.
Therefore, by rotating the second adjusting screw 59 with the second electric motor 62, the third dispenser 43 (that is, the third nozzle 64) can be moved straight in the Y direction with respect to the connecting member 45.

That is, the third dispenser 43 can be moved straight in a direction intersecting the extension line (rotation center of the dispenser) of the support shaft 46a of the electric motor 46.
In the embodiment, an example in which the third dispenser 43 is moved straight in a direction orthogonal to the extension line of the support shaft 46a of the electric motor 46 will be described, but the present invention is not limited to this.
By using the second electric motor 62 for the second pitch adjusting unit 52, the third nozzle 64 of the third dispenser 43 can be moved straight to an arbitrary position.
The third dispenser 43 is configured so that the adhesive can be discharged from the tip of the third nozzle 64 and the amount of the adhesive discharged from the third nozzle 64 can be adjusted.

In this way, the first electric motor 55 moves the second nozzle 58 straight in the Y direction, and the second electric motor 62 moves the third nozzle 64 straight in the Y direction, whereby the first nozzle 49 and the second nozzle The pitch of the 58 and the third nozzle 64 in the Y direction can be adjusted. That is, the pitch in the Y direction between the first dispenser 41, the second dispenser 42, and the third dispenser 43 (hereinafter, referred to as the pitch between dispensers) can be adjusted.

Further, by rotating the connecting member 45 with the electric motor 46, the first dispenser 41, the second dispenser 42, and the third dispenser 43 can be rotated along the XY plane.
The first nozzle 49 is arranged coaxially with the support shaft 46a of the electric motor 46. Therefore, the first dispenser 41, the second nozzle 58 of the second dispenser 42, and the third nozzle 64 of the third dispenser 43 rotate along the XY plane around the first nozzle 49 of the first dispenser 41. do.
Thereby, the pitch of the first nozzle 49, the second nozzle 58, and the third nozzle 64 in the Y direction (hereinafter referred to as the coating pitch) can be adjusted.
The coating pitch refers to the coating interval when the adhesive is applied to the member 8 to be coated by the first nozzle 49, the second nozzle 58, and the third nozzle 64.

Here, the first nozzle 49 is arranged at the center between the second nozzle 58 and the third nozzle 64 in the X direction. Therefore, by rotating the first dispenser 41, the second dispenser 42, and the third dispenser 43 around the first nozzle 49, the adjustment amount of the coating pitch of each dispenser 41 to 43 can be made uniform, so that the coating pitch can be adjusted. Can be easily managed.

In the first embodiment, an example in which the first dispenser 41, the second dispenser 42, and the third dispenser 43 are rotated around the first nozzle 49 will be described, but the present invention is not limited to this. As another example, for example, the first dispenser 41, the second dispenser 42, and the third dispenser 43 can be rotated around the second nozzle 58 and the third nozzle 64. Alternatively, it is also possible to rotate the first dispenser 41, the second dispenser 42, and the third dispenser 43 around a place other than the first nozzle 49, the second nozzle 58, and the third nozzle 64.

Next, an example of adjusting the coating pitches of the first dispenser 41, the second dispenser 42, and the third dispenser 43 of the coating device 3 of the first embodiment will be described with reference to FIGS. 4 to 9.
FIG. 4 is a plan view illustrating an example in which the second dispenser 42 and the third dispenser 43 of the coating apparatus 3 according to the first embodiment are moved straight.
As shown in FIG. 4, the first electric motor 55 of the first pitch adjusting unit 51 is driven to move the second dispenser 42 straight toward the first electric motor 55 side as shown by an arrow A. Further, the second electric motor 62 of the second pitch adjusting unit 52 is driven to move the third dispenser 43 straight toward the opposite side of the second electric motor 62 as shown by the arrow B.

FIG. 5 is a bottom view illustrating an example of adjusting the pitch between dispensers between the first nozzle 49, the second nozzle 58, and the third nozzle 64 of the coating device 3 according to the first embodiment.
As shown in FIG. 5, the first nozzle 49 of the first dispenser 41 is held at the first position H1 in the Y direction. The second nozzle 58 of the second dispenser 42 is positioned at the second position H2 in the Y direction. The third nozzle 64 of the third dispenser 43 is positioned at the third position H3 in the Y direction.

The first nozzle 49 is held at the first position H1 and the second nozzle 58 is positioned at the second position H2, so that the pitch between the first dispensers in the Y direction between the first nozzle 49 and the second nozzle 58 is P1. It has been adjusted to.
Further, the first nozzle 49 is held at the first position H1 and the third nozzle 64 is positioned at the third position H3, so that the pitch between the second dispensers in the Y direction between the first nozzle 49 and the third nozzle 64 Is adjusted to P2.
In this state, the pitch P1 between the first dispensers becomes the first coating pitch P1. Further, the pitch P2 between the second dispensers becomes the second coating pitch P2. That is, the pitch between the dispensers of the first nozzle 49, the second nozzle 58, and the third nozzle 64 can be widened.

FIG. 6 is a plan view illustrating an example in which the first dispenser 41, the second dispenser 42, and the third dispenser 43 of the coating device 3 according to the first embodiment are rotated in the counterclockwise direction.
As shown in FIG. 6, the electric motor 46 of the first pitch adjusting mechanism 34 rotates the connecting member 45 along the XY plane in the direction of arrow C (that is, in the counterclockwise direction).
As the connecting member 45 rotates along the XY plane, the first dispenser 41, the second dispenser 42, and the third dispenser 43 are placed on the XY plane about the first nozzle 49 of the first dispenser 41. Rotate in the direction of arrow C along.
Since the pitch between the dispensers of the first nozzle 49, the second nozzle 58, and the third nozzle 64 is widened, the first nozzle 49, the second nozzle 58, and the third nozzle are located at predetermined positions more than when the pitch between the dispensers is narrow. The amount of rotation for positioning the nozzle 64 can be increased.

FIG. 7 is a bottom view illustrating an example of adjusting the coating pitch between the first nozzle 49, the second nozzle 58, and the third nozzle 64 of the coating device 3 according to the first embodiment.
As shown in FIG. 7, the first nozzle 49 of the first dispenser 41 is held at the first position H1 in the Y direction. The second nozzle 58 of the second dispenser 42 is positioned at the fourth position H4 in the Y direction. The third nozzle 64 of the third dispenser 43 is positioned at the fifth position H5 in the Y direction.

The first nozzle 49 is held at the first position H1 and the second nozzle 58 is positioned at the fourth position H4, so that the third coating pitch in the Y direction between the first nozzle 49 and the second nozzle 58 becomes P3. It has been adjusted.
Further, the first nozzle 49 is held at the first position H1 and the third nozzle 64 is positioned at the fifth position H5, so that the fourth coating pitch in the Y direction between the first nozzle 49 and the third nozzle 64 is increased. It is adjusted to P4.
That is, the third coating pitch P3 is adjusted to be increased from the first coating pitch P1 (see FIG. 5). The fourth coating pitch P4 is adjusted to be increased from the second coating pitch P2 (see FIG. 5).

FIG. 8 is a plan view illustrating an example in which the first dispenser 41, the second dispenser 42, and the third dispenser 43 of the coating device 3 according to the first embodiment are rotated in the clockwise direction.
As shown in FIG. 8, the electric motor 46 of the first pitch adjusting mechanism 34 rotates the connecting member 45 along the XY plane in the arrow D direction (that is, in the clockwise direction).
As the connecting member 45 rotates along the XY plane, the first dispenser 41, the second dispenser 42, and the third dispenser 43 are placed on the XY plane about the first nozzle 49 of the first dispenser 41. Rotate in the direction of arrow D along.
Since the pitch between the dispensers of the first nozzle 49, the second nozzle 58, and the third nozzle 64 is widened, the first nozzle 49, the second nozzle 58, and the third nozzle are located at predetermined positions more than when the pitch between the dispensers is narrow. The amount of rotation for positioning the nozzle 64 can be increased.

FIG. 9 is a bottom view illustrating an example of adjusting the coating pitch between the first nozzle 49, the second nozzle 58, and the third nozzle 64 of the coating apparatus 3 according to the first embodiment.
As shown in FIG. 9, the first nozzle 49 of the first dispenser 41 is held at the first position H1 in the Y direction. The second nozzle 58 of the second dispenser 42 is positioned at the sixth position H6 in the Y direction. The third nozzle 64 of the third dispenser 43 is positioned at the seventh position H7 in the Y direction.

The first nozzle 49 is held at the first position H1 and the second nozzle 58 is positioned at the sixth position H6, so that the fifth coating pitch in the Y direction between the first nozzle 49 and the second nozzle 58 becomes P5. It has been adjusted.
Further, the first nozzle 49 is held at the first position H1 and the third nozzle 64 is positioned at the seventh position H7, so that the sixth coating pitch in the Y direction between the first nozzle 49 and the third nozzle 64 is increased. It is adjusted to P6.
The fifth coating pitch P5 is adjusted to be smaller than the first coating pitch P1 (see FIG. 5). The sixth coating pitch P6 is adjusted to be smaller than the second coating pitch P2 (see FIG. 5).

In this way, the first nozzle 49, the second nozzle 58, and the third nozzle 64 are moved straight in the Y direction to widen the pitch between the dispensers, and then the rotation of the first dispenser 41, the second dispenser 42, and the third dispenser 43. I tried to secure a large angle.
That is, by widening the pitch between the dispensers of the first nozzle 49, the second nozzle 58, and the third nozzle 64, the pitch between the dispensers is narrower, so that the first nozzle 49, the second nozzle 58, and the third nozzle are located at predetermined positions than when the pitch between the dispensers is narrow. The amount of rotation for positioning the nozzle 64 can be increased.

For example, when a stepping motor is used for the electric motor 46, widening the pitch between dispensers is for positioning the first nozzle 49, the second nozzle 58, and the third nozzle 64 at predetermined positions rather than narrowing the pitch. The number of steps of the electric motor 46 can be increased.
This makes it easier to finely adjust the coating pitch by the first nozzle 49, the second nozzle 58, and the third nozzle 64. For example, when the pitch between dispensers is narrow, it can be adjusted only between 0 and 1, but by widening the pitch between dispensers, it can be adjusted between 0, 0.5 and 1.0.
In other words, by adjusting the pitch between dispensers by the straight movement of the second pitch adjusting mechanism 35 and rotating a plurality of dispensers by the first pitch adjusting mechanism 34, it is possible to obtain only by the linear motion mechanism by the second pitch adjusting mechanism 35. The resolution of pitch adjustment that cannot be obtained is obtained.

With the coating pitches of the first nozzle 49, the second nozzle 58, and the third nozzle 64 adjusted, the member 8 to be coated (see FIG. 1) is moved in the XY directions and arranged at the coating position. In this state, the adhesive is discharged from the first nozzle 49, the second nozzle 58, and the third nozzle 64 while moving the member 8 to be coated in the Y direction, so that the adhesive is applied to the member 8 to be coated at a predetermined coating pitch. Can be applied.
Further, the discharge amount of the adhesive discharged from the first nozzle 49, the second nozzle 58 and the third nozzle 64 can be adjusted. By changing the amount of the adhesive applied to the member 8 to be coated in this way, the degree of freedom in the coating pitch of the member 8 to be coated can be increased.
Further, since the coating pitches of the first nozzle 49, the second nozzle 58, and the third nozzle 64 can be changed later, one coating device 3 can handle various coating pitches.

In the first embodiment, an example in which the member 8 to be coated (see FIG. 1) is moved in the XY directions to apply the adhesive to the member 8 to be coated at a predetermined coating pitch has been described, but the present invention is not limited to this. As another example, for example, while the coated member 8 is fixed, the coating device 3, that is, the first dispenser 41, the second dispenser 42, and the third dispenser 43 are moved in the XY directions to move the coated member 8 in the XY directions. It is also possible to apply the adhesive to the coating at a predetermined coating pitch.

Further, by using the electric motor 46 for the first pitch adjusting mechanism 34, the connecting member 45 can be rotated at an arbitrary position. Further, by using the first electric motor 55 and the second electric motor 62 for the second pitch adjusting mechanism 35, the second nozzle 58 of the second dispenser 42 and the third nozzle 64 of the third dispenser 43 can be placed at arbitrary positions. It can be moved straight.
Thereby, the coating pitches of the first nozzle 49, the second nozzle 58, and the third nozzle 64 can be arbitrarily changed according to the predetermined coating pitch on the member 8 to be coated.

According to the coating device 3 of the first embodiment, the first electric motor 55 of the first pitch adjusting unit 51 is driven to move the second dispenser 42 in a straight line with respect to the support member 31. Further, the second electric motor 62 of the second pitch adjusting unit 52 is driven to move the third dispenser 43 in a straight line with respect to the support member 31. Thereby, the pitches P1 and P2 between a plurality of dispensers can be adjusted. Therefore, the pitches P1 and P2 between the plurality of dispensers can be adjusted individually.

In this state, the first dispenser 41, the second dispenser 42, and the third dispenser 43 are rotated by the electric motor 46 of the first pitch adjusting mechanism 34 with respect to the support member 31, so that the dispensers 41, 42, and 43 The coating pitches P1 to P6 can be adjusted individually.
Therefore, the coating pitches P1 to P6 of the first dispenser 41, the second dispenser 42, and the third dispenser 43 can be changed in various ways. As a result, the adhesive can be applied corresponding to an arbitrary coating pitch of the member 8 to be coated.
Further, the coating pitches P1 to P6 can be changed without increasing the first to third dispensers 41 to 43. As a result, it is possible to suppress the increase in size of the coating device 3 and further reduce the cost of the coating device 3.

Further, by individually adjusting the coating pitches P1 to P6 of the first dispenser 41, the second dispenser 42, and the third dispenser 43, the adhesive can be efficiently applied to the member to be coated 8. Therefore, it is possible to shorten the application time of the adhesive to the member 8 to be coated (see FIG. 1).
On the other hand, for example, in the case of a coating device provided with a single dispenser, it takes a long time to apply the adhesive to the member 8 to be coated, as in the coating device 3 of the first embodiment. In order to reduce the coating time on the member to be coated 8 in the same manner as in the coating device 3 of the first embodiment, it is necessary to individually provide a large number of dispensers in a state of being independent of the coating device. Therefore, the size of the coating device becomes large, and the cost of the coating device is suppressed.

Further, according to the coating device 3, the coating pitches P1 to P6 of the first dispenser 41, the second dispenser 42, and the third dispenser 43 can be individually adjusted, so that one coating device 3 can have various coating pitches. It can correspond to the member 8 to be coated.
