Abstract

PROBLEM TO BE SOLVED: To provide a print setter not liable to bring about the unevenness of a printing film thickness or damage to a screen. SOLUTION: A substrate 10 placed on the printer setter 56 is sucked from a rear surface side of a handler 74 by the handler 74 provided in an opening 68 of a placing surface 66, when the handler 74 which sucks the substrate 10 is moved along a direction parallel to the placing surface 66. Accordingly, one side of the substrate 10 is pressed against positioning pins 62 and 64 fixed to the surface 66 to be positioned to a predetermined constant printing position. At this time, since the opening 68 is provided at an inside from the outer periphery of the substrate 10, a squeegee does not pass over a hole which locally exists when the substrate 10 is slid on the screen to coat a thick film printing paste on the substrate 10. Thus, the print setter 56 which is not liable to bring about the unevenness of wear of the squeegee due to passage of the squeegee over a long hole or the unevenness of the printing film thickness or the damage to the screen is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing setter on which a substrate is placed when performing screen printing on one surface of the substrate.

[0002]

2. Description of the Related Art For example, when a thick film conductor, a thick film resistor, a thick film insulator, etc. are formed on one surface of a substrate in a manufacturing process of a thick film circuit board, a printing screen provided with a predetermined opening pattern is used. Is used to sequentially apply a thick-film printing paste for forming each of the thick films to one surface of the substrate. In such thick film screen printing, a substrate placed on a printing setter is positioned below the printing screen, and the squeegee is moved in one direction while pushing down the printing screen toward the substrate with a squeegee. Then, the thick film printing paste is applied.

[0003]

When the substrate is placed on the print setter, the substrate is placed on the print setter so that the relative positional accuracy of each layer of the thick film formed sequentially can be obtained. It is positioned in a certain posture. However, in the conventional print setter, as shown in FIG. 1, for example, three fixing pins 14 and 16 fixedly protruding from a mounting surface 12 on which the substrate 10 is mounted, and penetrate the mounting surface 12. The fixing pins 14 in the slots 18 and 20
Movable pins 22 and 24 movable toward one or the other of the first and second movable pins, respectively.
The substrate 10 is positioned by pressing the substrate 10 toward the fixing pins 14 and 16 with the reference numerals 2 and 24.
The sliding direction of the squeegee is set to one of the directions A and B in the drawing or the opposite direction. However, no matter which sliding direction is selected, the central portion of the squeegee has two long holes 18 and 20.
, Ie, in the case of the direction A,
In the case of the direction, it passes over the elongated hole 20.

For this reason, when the sliding direction is set to the direction A, the main part of the section taken along the line II-II in FIG. 1 is enlarged, and as shown in FIG. When sliding over the long hole 20), the portions 28a, 2a pressed against the opening edge of the long hole 18
While the wear amount of the squeegee 8a is relatively large, the wear amount of the portion 28b located therebetween is relatively small, so that the wear amount of the squeegee 28 is not uniform in the longitudinal direction. As a result, due to the difference in the amount of wear, there is a problem that the amount of the thick film printing paste extruded from the printing screen omitted in FIG. 2 differs, and the film thickness varies. . In addition, in the portion 28a where the amount of wear is large, there is a problem that the printing screen interposed between the print setter and the squeegee 28 is worn and the damage is increased. Incidentally, the variation of the film thickness is as follows.
For example, a thick-film resistor causes a variation in its resistance value, and a thick-film conductor causes a variation in its conductivity. Therefore, as the required accuracy increases, even a slight variation becomes unacceptable.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a print setter in which variations in a printed film thickness and damage to a screen hardly occur.

[0006]

In order to achieve the above object, the gist of the present invention is to perform screen printing on one surface of a substrate and place the substrate at a predetermined fixed printing position. A print setter for holding on the mounting surface, and (a) a positioning member fixed to the mounting surface for positioning by pressing one side of the substrate,
(b) an opening provided on the mounting surface within a range inside the outer periphery of the substrate, and (c) a suction member provided in the opening to suction the substrate from the back side thereof When,
(d) a driving device for moving the suction member in a direction parallel to the mounting surface in order to press the sucked substrate against the positioning member.

[0007]

According to this structure, the substrate mounted on the print setter is sucked from the back side by the suction member provided in the opening of the mounting surface, so that the suction member holding the substrate is sucked. Is moved in a direction parallel to the mounting surface by the driving device, one side of the substrate is pressed against a positioning member fixed to the mounting surface, whereby the substrate is positioned at a predetermined printing position. At this time, the squeegee slides on the screen to apply the thick-film printing paste to the substrate because the opening provided on the mounting surface is provided only in the area inside the outer periphery of the substrate. The squeegee does not pass over the locally existing hole when it is made to squeeze. In other words, since a force for pressing the substrate toward the positioning member is applied from the back surface, not from the end surface of the outer periphery, a long hole for moving the member for pressing the substrate is formed from the outer periphery. Need not be provided outside. Therefore, since there is no variation in squeegee wear due to sliding of the squeegee so as to pass over the long hole, a print setter which is less likely to cause variations in print film thickness and screen damage is obtained. Can be

[0008]

Preferably, (a-2) the positioning member includes a first reference portion and a second reference portion against which mutually adjacent first and second sides of the substrate are pressed. (D-2) the driving device includes a predetermined first direction in which the first side is pressed against the first reference portion, and the first side corresponds to the first reference portion. The suction member is sequentially moved along a predetermined second direction in which the second side is pressed against the second reference portion while being pressed. With this configuration, the suction member is sequentially moved along the first direction and the second direction by the driving device, and the two sides (the first side and the second side) of the substrate are moved to the first reference portion of the positioning member and the first side. The substrates are positioned by being pressed against the second reference portions, respectively. Therefore, there is an advantage that the substrate can be positioned regardless of the initial position on the mounting surface.

Preferably, (a-3) the first reference portion includes a first pressing portion and a second pressing portion separated from each other by a predetermined distance, and (c-2) the suction member comprises: The substrate and the mounting surface adsorb the substrate so as to be relatively rotatable around a normal line of the mounting surface according to a pressing force acting on the first side, and (d-3) the driving device includes: , The first side is the first
The suction member is moved in the first direction until the suction member is pressed against both the pressing portion and the second pressing portion.
With this configuration, the substrate can be rotated relative to the mounting surface around its normal line in a state of being sucked, so that when the sucking member is moved along the first direction by the driving device. When the first side is first pressed against one of the first pressing portion and the second pressing portion, the substrate is placed on the mounting surface in accordance with the pressing force until the first side is pressed against the other. Relative rotation. Therefore, even when the substrate is placed on the placing surface in a direction inclined with respect to the direction at the predetermined printing position, the inclination is corrected by pressing the first side against the first reference portion. There are advantages.

Preferably, the suction member abuts on the back surface of the substrate when the suction is performed in accordance with the pressing force acting on the substrate when the first side is pressed against the first reference portion. The substrate is sucked so that the suction surface to be moved and the substrate are relatively moved. In this case, since the relative rotation between the substrate and the mounting surface is realized by the slip between the substrate and the suction surface, there is an advantage that a mechanism for performing the relative rotation is unnecessary.

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 3 shows a screen printing machine (hereinafter referred to as a printing machine) 3 provided with a print setter according to one embodiment of the present invention.
FIG. 3 is a diagram for explaining a configuration of a main part of No. 0; In FIG. 1, a printing machine 30 forms a circuit pattern on one surface (printing surface) 32 of a ceramic substrate 10 made of, for example, alumina or the like, and manufactures a thick film circuit board. And a thick-film printing paste for forming a thick-film resistor, a thick-film insulating layer and the like is applied to one surface 32 of the thick-film resistor using a thick-film screen printing method.

The printing press 30 includes a printing mechanism 38 on which a squeegee 34 and a scraper (or scoop) 36 are supported so as to be able to move up and down, and a moving device 40 for moving the printing mechanism 38 in the left-right direction in FIG. And a print table 44 for transferring the substrate 10 mounted on the squeegee 34 and the scraper 36 to a lower side of a screen plate 42 provided below the squeegee 34 and the scraper 36. Is provided on the main body 46. The moving device 40 includes, for example, a pair of bearings 48, 4
8, a screw shaft 50 supported by the bearing 48 and screwed into a part of the printing mechanism 38, a motor 52 for rotating the screw shaft 50 around the axis at a desired rotational speed, and the like. . When the motor 52 is rotated forward or backward, the printing mechanism 38 is moved in either the left or right direction in the drawing.
That is, the squeegee 34 and the scraper 36 are moved in a squeezing (sliding) direction or a paste returning direction that matches the left-right direction in the drawing.

FIGS. 4A and 4B are views for explaining the configuration of the print table 44. FIG. 4A is a plan view seen from above in FIG. 3, and FIG. 4B is bb in FIG. Each corresponds to a sectional view. In the figure, the print table 44 has, for example, an overall rectangular shape in plan view,
The table includes a table body 54 and a rectangular print setter 56 fitted on the inner peripheral portion thereof. The table body 5
4 has a stepped portion 58 lower than its upper surface.
The print setter 56 is fitted in a stepped portion 58 of the print setter 56. Since the depth dimension of the stepped portion 58 is substantially equal to the thickness dimension at the outer peripheral edge of the print setter 56, there is no step at their boundary.

The print setter 56 has a concave portion 60 formed by making the area inside the outer peripheral edge of the print setter a predetermined distance or more slightly lower than the outer peripheral edge. That is, the entire upper surface of the print table 44 is not flat. The concave portion 60 has a substantially rectangular outline along the outer periphery of the print setter 56. Of the four sides, two or one on the lower side and two on the left side in the mutually adjacent figure Positioning pin 6
2, 64 are provided respectively. Positioning pin 6
The protrusions 2 and 64 are provided such that the length of the recess 60 protruding from the bottom surface 66 is slightly smaller than the depth thereof. Therefore, its upper end surface is
At a height slightly lower than the upper surface of the. In this embodiment, the two positioning pins 62 constitute a first reference portion, and the positioning pins 64 constitute a second reference portion.
Each of the positioning pins 62, 62 is a first pressing portion and a second pressing portion.
It corresponds to either one or the other of the pressing portions. The bottom surface 66 corresponds to a mounting surface.

The depth of the recess 60 is substantially the same as the thickness of the substrate 10. Therefore, substantially the entire upper surface of the print table 44 becomes a substantially flat surface in a state where the substrate 10 is placed in the concave portion 60.

An opening 68 is provided in the recess 60 of the print setter 56 so as to penetrate the recess 60 in the thickness direction. As shown in FIG. The opening 70 is provided over a range wider than 68. For this reason, as shown in FIG. 5 in which the main part in FIG. 4B is enlarged, when the substrate 10 is placed on the printing setter 56, a part of the back surface 72 is in the openings 68 and 70. It is in a state of being exposed to. In FIG. 4B, the substrate 10 is omitted for convenience of illustration.

Returning to FIG. 4, a cylindrical substrate driving handler (hereinafter simply referred to as a handler) 7 is provided in the openings 68 and 70 from which the substrate back surface 72 is exposed.
4 are arranged so as to protrude from below the print setter 56. The handler 74 includes, together with an exhaust tube 76 connected to the lower end thereof and an exhaust pump 78 connected to the other end of the exhaust tube 76, an adsorption device 80 for adsorbing and holding the substrate 10 from the back surface 72. Make up. The substrate 10 placed on the placing surface 66
When the exhaust pump 78 of the suction device 80 is operated, the air is sucked from the opening of the handler 74 to be sucked by the handler 74. In addition, the handler 74
Substantially the whole is made of a material having sufficiently high rigidity such as synthetic resin or metal, and an annular suction portion 82 made of a relatively soft material such as silicone resin is provided at the tip. The suction portion 82 is provided to increase the airtightness in the state of contact between the front end surface (suction surface) 84 and the substrate back surface 72 when the handler 74 suctions the substrate 10. The handler 74 is located between the two positioning pins 62, that is, between a pair of parallel planes perpendicular to one straight line passing therethrough and passing through the two positioning pins 62 respectively. In the present embodiment, the above-described handler 74 corresponds to a suction member.

In addition, below the table body 54, which is omitted in FIG. 4B, below the handler 74, as shown in FIG. A first cylinder 86 and a second cylinder 88 are provided. The first cylinder 86 is fixedly attached to the lower surface of the printing table 44, for example, and can project and retract in the vertical direction in FIG. 4A, that is, the direction approaching or separating from the positioning pin 62, in parallel with the mounting surface 66. An output rod 90 is provided. The second cylinder 88
A cylinder base 92 is fixed to the upper surface. On the other hand, the second cylinder 88 is parallel to the mounting surface 66 and in the left-right direction in FIG.
4 is provided with an output rod 94 which can be protruded and retracted in a direction approaching or separating from the fourth. Output rod 94
A support member 96 is fixed to the front end of the support member 96, that is, the left end in the drawing. The suction surface 84 of the handler 74 is the same as or slightly lower than the mounting surface 66 by being attached to the support member 96 on the cylindrical side surface so that neither relative movement nor relative rotation is possible. It is supported to be located at the height position.

The driving directions of the output rods 90 and 94 are orthogonal to each other, and when the first cylinder 86 is operated, the cylinder base 92 and the second cylinder 88 mounted thereon are moved as shown in FIG. When the second cylinder 88 is operated in the vertical direction in FIG. 4A, the support member 96 and the handler 74 attached to the side surface thereof are moved in the horizontal direction in FIG. Therefore, the handler 74 is moved in two directions parallel to the mounting surface 66 and orthogonal to each other by the operation of the first cylinder 86 and the second cylinder 88. Therefore, in the present embodiment, the first cylinder 86, the second cylinder 88, the cylinder base 9
The drive member 2 and the support member 96 move the suction member, that is, the handler 74, in a direction parallel to the mounting surface 66. The driving direction of the output rod 90 corresponds to the first direction, and the driving direction of the output rod 94 corresponds to the second direction.

Since the handler 74 and the driving device are configured as described above, the substrate 10 mounted on the mounting surface 66 is attracted to the handler 74 when the exhaust pump 78 is operated. Is moved together with the handler 74. That is, it is moved in a first direction approaching or separating from the positioning pin 62 and in a second direction approaching or separating from the positioning pin 64.

In these figures, (a) shows that the substrate 10 is placed and

The handler 74 also abuts against the one side 10a is one of the positioning pins 62 of the substrate (b), the moved continuously in the same H ₂ direction as H _1. However, the substrate 10 whose one side 10a abuts against one of the positioning pins 62 cannot move downward (that is, translate) in the figure while maintaining the posture shown in FIG. Therefore, the two positioning pins 62, 62
A rotational moment acts on the substrate 10 around its normal line by the force received from the handler 74 located in between and the one positioning pin 62. At this time, the suction force of the handler 74 is set to such a degree that slippage may occur when a certain amount of force acts from the outer peripheral end surface of the substrate 10. while sliding the suction surface 84 of the back surface 72 and handler 74 remains held at the its rear surface 7 as indicated by the arrow B ₂

(c) shows a state where the substrate 10 is rotated in this way until one side 10a of the substrate 10 abuts on the other positioning pin 62. one-dot chain line in (c) is shows the position of the substrate 10 and the handler 74 at a stage (b), while the substrate 10 is rotated, the handler 74 is only slightly displaced in H ₂ directions . Since the substrate 10 is a parallel flat plate having a uniform thickness and is mounted on the substantially flat mounting surface 66, the above-described normal line coincides with the normal line of the mounting surface 66. That is, the handler 74 holds the substrate 10 in a state of being relatively rotated around the normal line of the substrate 10.

As described above, when one side 10a of the substrate abuts both of the two positioning pins 62, 62, one side
Since the positioning is performed on the 10a side, that is, the position and the direction of one side 10a thereof match the expected position and the direction in the vertical direction of the drawing, that is, the first direction in which the handler 74 is directed to the positioning pin 62, the handler 74 extends The movement of the substrate 10 in that direction ends.

In the subsequent stage, the substrate 10 is positioned by holding the first cylinder 86 in the operating state.

4 shows a stage of completion of the movement abutting on No. 4, that is, a stage where the positioning is completed in this direction. In this embodiment, the one side 10b corresponds to a second side adjacent to the first side. As described above, the positioning in the present embodiment is performed in substantially the same procedure as when the conventional print setter shown in FIG. 1 is used.

The application of the thick-film printing paste to the upper surface of the substrate 10 is started after the positioning of the substrate 10 is completed, and the squeegee 38 shown in FIG. 3 is lowered. Note that the positioning of the substrate 10 as described above is performed by using FIG.
May be performed at a printing position indicated by a solid line, or may be performed at a retracted position indicated by a dashed-dotted line, that is, a position at which the substrate 10 is replaced on the print table 44. In any case, the printing process of the substrate 10 is performed by moving the printing table 44 integrally provided with the handler 74 and the driving mechanism for the positioning from the position indicated by the dashed line in the drawing to the position indicated by the solid line. It will be implemented after being moved. It should be noted that a mechanism for moving the print table 44 and the like are omitted in the drawing.

When the positioning is completed and the printing process is performed, the opening 68 provided on the mounting surface 66 is closed by the substrate 10. In other words, the opening 6
The size of 8 is determined so as to be inside the outer periphery according to the size of the substrate 10 placed thereon. Therefore, assuming that the sliding direction of the squeegee 34 indicated by a dashed line in FIG.
The squeegee 3 having a length substantially equal to the length of one side of the squeegee
The intermediate portion in the longitudinal direction of the printing table 4 is a portion actually used for printing. As shown in FIG. 7 about a section taken along line VII-VII in FIG. Has no local openings.

FIG. 7 shows the print setter 5 of this embodiment.
6 shows the state of execution of the printing process in the case where the squeegee 6 is used. The squeegee 34 which can slide the screen 98 in a direction perpendicular to the paper surface while pushing down the screen 98 toward the print setter 56 is the conventional squeegee shown in FIG. Unlike when a print setter is used, it will be slid on the upper surface of the print setter 56 where there are no local holes. Therefore, the amount of wear of the squeegee 34 does not vary within the range A necessary for printing due to the existence of the slots 18 and 20 (see FIG. 1).

In short, according to the present embodiment, the mounting surface 66
The substrate 74 mounted on the print setter 56 is sucked from the back side by the handler 74 provided in the opening 68 of the printer, so that the handler 74 sucking the substrate 10 is parallel to the mounting surface 66 by the driving device. When the substrate 10 is moved along a predetermined direction, the sides 10a, 10b of the substrate 10 are pressed against the positioning pins 62, 64 fixed to the mounting surface 66, so that the substrate 10 has a constant posture, that is, a predetermined constant. Is positioned at the printing position. At this time,
Since the opening 68 provided on the mounting surface 66 is provided only in a range inside the outer periphery of the substrate 10, the squeegee 34 is moved on the screen 98 to apply the thick film printing paste to the substrate 10. When the squeegee is slid, the squeegee 34 does not pass over the locally existing hole. That is, since a force for pressing the substrate 10 toward the positioning pins 62 and 64 is applied not from the outer peripheral end surface but from the rear surface 72, a long force for moving the member for pressing the substrate 10 is provided. It is not necessary to provide the hole outside its outer periphery. For this reason, there is no variation in the wear of the squeegee 34 due to the sliding of the squeegee 34 so as to pass over the long hole.
The print setter 56 in which the damage of the print 8 is unlikely to occur is obtained.

In the print setter 56 of the present embodiment, a groove exists between the substrate 10 and the outer peripheral edge of the concave portion 66. However, regardless of whether the sliding direction of the squeegee 34 is the S direction in FIG. 4 or the direction perpendicular to the S direction, this groove is either uniform over the entire printing range A or is determined to be outside the printing range. Has no effect.

Also, in this embodiment, the handler 74 is sequentially moved in the first direction and the second direction by the driving device, and the two sides 10a, 10b of the substrate 10 are pressed against the positioning pins 62, 64, respectively. As a result, the substrate 10 is positioned. Therefore, there is an advantage that the substrate 10 can be positioned regardless of the initial position on the mounting surface 66.

In this embodiment, since the substrate 10 can be rotated relative to the mounting surface 66 about its normal line in a state where the substrate 10 is sucked, the handler 74 causes the handler 74 to move in the first direction. If one side 10a is pressed first on one of the positioning pins 62, 62 when it is moved along, the substrate 10 is placed according to the pressing force until it is pressed on the other. It is rotated relative to the placing surface 66. Therefore, even when the substrate 10 is placed on the placement surface 66 in a direction inclined with respect to the direction at the predetermined printing position, there is an advantage that the inclination can be easily corrected.

Further, in this embodiment, since the relative rotation between the substrate 10 and the mounting surface 66 is realized by the slip between the substrate 10 and the suction surface 84, no mechanism for relative rotation is provided. Since this is not done, the complexity of the whole apparatus can be avoided.

Although the embodiment of the present invention has been described in detail with reference to the drawings, the present invention can be implemented in other embodiments.

For example, in the embodiment, the case where the present invention is applied to the print setter 56 which is used by being fitted into the print table 44 has been described. However, the position can be fixed directly to the main body 46 or moved in the same manner as in the embodiment. The invention applies analogously to a printing setter that can be arranged as possible.

In the embodiment, the positioning pins 6
Although the positioning members are constituted by 2 and 64, the positioning members may be constituted by various shapes such as a strip or a rectangular parallelepiped.

In the embodiment, after the substrate 10 is moved toward one positioning pin 62 to be positioned in that direction, and then moved toward the other positioning pin 64, the substrate 10 is positioned in two stages. Was implemented, but by appropriately changing the moving direction,
Positioning can be performed only by one-step movement.

Further, in the embodiment, the handler 74 functioning as the suction member is driven by the first cylinder 86 and the second cylinder 88 composed of air cylinders. The driving method is as described in the embodiment. Various known XY drive mechanisms, cam mechanisms, and the like can be used as long as they can be sequentially moved in two directions or can be moved in an appropriate direction that can perform positioning once.

Further, in the embodiment, the relative rotation between the mounting surface 66 and the substrate 10 is realized by the slip between the handler 74 and the substrate 10, but the handler 74 is pressed according to the pressing force acting on the substrate 10. Various known relative rotation mechanisms such as a rotatable configuration may be used.

Although not specifically exemplified, the present invention
Various changes can be made without departing from the spirit of the invention.
