Description

  The present invention relates to a printing apparatus and a printing method.

  As one of methods for forming a circuit pattern of an electronic device used in a display or the like on a substrate to be printed such as a glass substrate or a film substrate, a printing method has been proposed. As an example of such a printing method, a reverse printing method is known (see, for example, Patent Document 1). By such a printing method, the cost for forming the pattern can be suppressed, and a fine circuit pattern on the order of several microns can be formed.

  In the reversal printing method, a roller transfer cylinder (hereinafter also referred to as “transfer roller”) may be used. In the reverse printing method using a transfer roller, for example, an application process in which ink is applied to the surface of a transfer roller having a silicone resin layer on the surface to form an application surface, and the transfer roller that has undergone the application process is projected into a predetermined shape. Rolling on a printing plate, which is a relief plate with a portion formed thereon, a removal step for receiving ink on the coated surface corresponding to the convex portion of the printing plate, and a transfer for transferring the ink remaining on the coated surface to the substrate to be printed The process is performed (for example, refer to Patent Document 2).

  In the reversal printing method using a transfer roller, the printing plate formed of a glass plate and the transfer roller are moved relative to each other, and the transfer roller is rolled on the printing plate to form the printing plate pattern on the transfer roller. To do. Next, the ink pattern on the transfer roller is transferred to the print substrate by moving the print substrate and the transfer roller relative to each other so that the transfer roller rolls on the print substrate. According to this technique, the same resolution as that of a pattern formed by a photolithography method can be obtained easily and inexpensively.

  In such a reversal printing machine, generally, the entire substrate to be printed is printed. Moreover, in the reverse printing machine using a printing plate, the same pattern is repeatedly used. Therefore, the reverse printing machine can form a predetermined pattern on the substrate to be printed at low cost. On the other hand, an ink jet type printing machine is known as a printing machine that does not require a printing plate (so-called plateless printing machine).

  By the way, in a reversal printing machine, the pattern of a some block may be printed collectively with respect to the to-be-printed substrate unit by which the several block used as printing object is arrange | positioned. However, on the substrate unit to be printed, the position and orientation of each block may be shifted from the design value in some cases. In such a case, if batch printing is performed on the substrate unit to be printed using a printing plate created according to the design value, printing is performed with a pattern shifted to each block. For this reason, it is difficult to print a fine pattern that requires high positional accuracy.

  Further, since the Ikunjet printer can perform printing for each block, it is possible to print a pattern on each block with a certain degree of accuracy even if the position and orientation of each block are shifted. However, in an ink jet printer, there is a limit to the amount of ink ejected from the nozzles, and it is difficult to control the position of the ink after ejection. Further, in an ink jet printer, even if the number of nozzles is increased, it takes longer to print than a reverse printer. For this reason, it is difficult for the ink jet type printing machine to make the pattern formation finer, more accurate, and faster.

  One aspect of the present invention is a printing apparatus, which includes a roller, a blanket, a detection unit, a moving unit, and a printing unit. The blanket is provided on the surface of the roller and has a transfer area. The detection unit detects position information indicating a position and an orientation of the printed material for each printed material on a printed material on which a plurality of printed materials are arranged at least in the rotation axis direction of the roller. A moving part moves a to-be-printed base material for every to-be-printed material so that a roller and to-be-printed material may become predetermined | prescribed positional relationship based on the positional information detected by the detection part. The printing unit covers the printing pattern formed in the transfer area of the blanket by rotating the roller while pressing the blanket on the printing substrate on the printing substrate moved by the moving unit for each printing substrate. Print on printed matter.

  According to various aspects and embodiments of the present invention, a predetermined pattern can be printed on each substrate with high accuracy even if the position and orientation of each substrate disposed in the substrate to be printed are shifted. it can.

[Configuration of Printing Apparatus 1]
FIG. 1 is a perspective view illustrating an example of a configuration of a printing apparatus 1 according to the first embodiment. A printing apparatus 1 shown in FIG. 1 includes a roller cylinder 20 and a main body 2. The main body 2 is provided with a plurality of linear guides 3 extending in the X-axis direction of FIG. In the following drawings, the X axis, the Y axis, and the Z axis are described as necessary, but the X axis, the Y axis, and the Z axis in each drawing are the X axis, Y axis, and Y axis shown in FIG. Each corresponds to an axis and a Z-axis.

  A base 5 is provided on the linear guide 3, and the base 5 is moved in the X-axis direction along the linear guide 3 by a linear motor 4 provided at a lower portion of the base 5. A plurality of linear guides 6 extending in the Y-axis direction of FIG. 1 are provided on the upper surface of the base 5, and a printed substrate table 8 is provided on the linear guide 6.

A printed substrate unit 10 in which a plurality of printed substrate blocks 9 are arranged is placed on the printed substrate table 8. Hereinafter, the printed substrate block 9 is simply referred to as a block 9. The printed substrate unit 10 is a unit in which a plurality of blocks 9 are hardened with a resin or the like and the terminal surfaces are exposed. The block 9 is an example of a printing material, and the printing substrate unit 10 is an example of a printing substrate.

  Here, as shown in FIG. 2, for example, a plurality of blocks 9 are arranged in the substrate unit 10 to be printed.

The linear motor 7 can move the printed substrate table 8 in the Y-axis direction by at least the length of (L1 + d1) × (n−1). In this embodiment, since the maximum value n of the number of blocks 9 is 2, the linear motor 7 can move the printed substrate table 8 in the Y-axis direction at least by the length of L1 + d1.

Each block 9 is transferred (printed) with ink of a printing pattern formed on the surface of the blanket 21 wound around the outer periphery of the roller cylinder 20.

  The printed substrate table 8 includes a holding unit 80 that fixes the printed substrate unit 10 placed on the printed substrate table 8.

The six-axis drive mechanism 81 can finely adjust the displacement of each block 9 with respect to the roller cylinder 20 in each of the six axes. The moving coordinate system of the six-axis drive mechanism 81 is adjusted in advance so as to coincide with the coordinate system of the substrate table 8 to be printed. The printed substrate table 8 is an example of a moving unit. In the six-axis drive mechanism 81, the mechanism that moves the substrate unit 10 to be printed in the X-axis direction and the Y-axis direction is an example of a first moving unit. In the six-axis drive mechanism 81, the mechanism that rotates the substrate unit 10 to be printed in the direction of the rotation Θ around the Z axis is an example of a second moving unit. In the six-axis drive mechanism 81, the mechanism for rotating the substrate unit 10 to be printed in the direction of the rotation Ψ around the X axis and the direction of the rotation rod around the Y axis is an example of a third moving unit.

  Further, a base 13 is provided on the linear guide 3, and the base 13 is moved in the X-axis direction along the linear guide 3 by a linear motor 14 provided at a lower portion of the base 13. A plurality of linear guides 15 extending in the Y-axis direction are provided on the base 13, and a plate table 17 is provided on the linear guide 15. The plate table 17 is moved in the Y-axis direction along the linear guide 15 by a linear motor 16 provided at the lower part of the plate table 17. A plate unit 19 on which a plurality of printing plates 18 are arranged is placed on the plate table 17. The plate unit 19 is fixed on the plate table 17 by a holding unit 170 provided on the plate table 17. The holding unit 170 fixes the plate unit 19 on the plate table 17 by a vacuum chuck, a mechanical fixing method, or the like. The plate unit 19 is an example of a removal substrate, and each printing plate 18 is an example of a removal pattern. Note that the plate unit 19 placed on the plate table 17 is also attached to the plate table 17 in the directions of the X, Y, and Z axes shown in FIG. 1, the rotation Ψ around the X axis, and the rotation axis around the Y axis. , And a 6-axis drive mechanism that can be moved in the direction of the rotation Θ around the Z axis may be incorporated. The linear motor 14 and the linear motor 16 are examples of the removal base material moving unit.

  FIG. 3 is a diagram showing an example of the arrangement of the printing plate 18 in the plate unit 19. In the plate unit 19, for example, as shown in FIG. 3, a plurality of flat plate-shaped printing plates 18 are arranged. Each plate unit 19 includes a concave portion 180 (a portion shown in white in FIG. 3) corresponding to a printing pattern, and a convex portion 181 (a portion blackened in FIG. 3) for absorbing and removing excess ink. ) And an alignment mark 182 for alignment. In the plate unit 19 illustrated in FIG. 3, four printing plates 18 having a width L2 in the Y-axis direction are arranged at intervals of d2 in the Y-axis direction.

  The number of printing plates 18 included in the plate unit 19 may be 3 or less, or 5 or more. The number of printing plates 18 included in the plate unit 19 is preferably equal to or more than the number of blocks 9 included in the substrate unit 10 to be printed. Thereby, the frequency of cleaning of the substrate unit 10 to be printed can be reduced. Further, in the plate unit 19 illustrated in FIG. 3, a plurality of printing plates 18 are arranged in the X-axis direction and the Y-axis direction, but the plurality of printing plates 18 are arranged in one row in the X-axis direction or the Y-axis direction. May be arranged.

  The roller cylinder 20 is a blanket cylinder in which a water-repellent blanket 21 formed of, for example, silicone is wound around the outer periphery. The blanket 21 is sequentially pressed against the printing plate 18 in the plate unit 19 and the block 9 in the substrate unit 10 to be printed in the printing process. For this reason, the blanket 21 is formed of a material having cushioning properties. For example, the blanket 21 is pressed against the printing plate 18 and the block 9 in the Z-axis direction shown in FIG. The direction in which the blanket 21 is pressed against the printing plate 18 and the block 9 is an example of the pressing direction. Of the surface of the blanket 21, the region to which the ink film is applied is an example of a transfer region.

  In the present embodiment, the width of the blanket 21 in the rotation axis direction of the roller cylinder 20 (that is, the Y-axis direction in FIG. 1) is the width in the Y-axis direction of each block 9 disposed in the substrate unit 10 to be printed, and This corresponds to the width of each printing plate 18 arranged in the plate unit 19 in the Y-axis direction. For example, the width of the blanket 21 in the rotation axis direction of the roller cylinder 20 is a length corresponding to the minimum area necessary for printing a predetermined printing pattern on one block 9.

  Since the width of the blanket 21 in the Y-axis direction is a length corresponding to the width of the minimum area necessary for printing a predetermined printing pattern on one block 9, the blanket 21 and the roller cylinder 20 are reduced in size. Can be As a result, the weight of the roller cylinder 20 can be reduced, and the resonance frequency between the roller cylinder 20 and the printed substrate table 8 and the resonance frequency between the roller cylinder 20 and the plate table 17 can be increased. Thereby, resonance due to vibration from the outside of the printing apparatus 1 is less likely to occur, and blurring of the print pattern during printing is suppressed. Thereby, a predetermined pattern can be printed on each block 9 with high accuracy. In the printing apparatus 1 according to the present embodiment, since printing is performed for each block 9, the circumferential length of the blanket 21 can be shortened. Thereby, the blanket 21 and the roller cylinder 20 can be further reduced in size.

  Here, in the substrate unit 10 to be printed, for example, as shown in FIG. 2, a plurality of blocks 9 are arranged in the Y-axis direction. The linear motor 7 that moves the printed substrate unit 10 in the Y-axis direction can move the printed substrate table 8 by at least the length of (L1 + d1) × (n−1). As a result, the linear motor 7 moves each of the plurality of blocks 9 arranged in the Y-axis direction to a position below the blanket 21 having a width of one block in the Y-axis direction (that is, the width of L1). Can do. Thereby, the blanket 21 can print a printing pattern on the block 9 for each block 9.

  Both ends of the rotation shaft of the roller cylinder 20 are supported by bearings fixed to the bracket 22. The entire bracket 22 can be moved in the vertical direction (that is, the Z-axis direction in FIG. 1) by the vertical mechanisms 23a and 23b. The vertical mechanisms 23a and 23b can convert the rotation of the drive motor into a linear motion in the vertical direction with screws, and can vertically move both ends of the rotating shaft of the roller cylinder 20 independently. One end of the roller body 20 is connected to a rotation mechanism 24 for rotation driving fixed to the bracket 22. In the Z-axis direction, fine adjustment of the position of the roller cylinder 20 with respect to the printing plate 18 and the block 9 is performed by the vertical mechanisms 23a and 23b. A coater 25 for applying ink to the blanket 21 is provided on the upper portion of the roller cylinder 20. The vertical mechanisms 23a and 23b and the rotation mechanism 24 are examples of a printing unit.

  The mark detector 26 shoots the alignment mark provided in each block 9 in the printed substrate unit 10 placed on the printed substrate table 8, and based on the position and orientation of the taken alignment mark, Position information indicating the position and orientation of each block 9 with respect to the roller cylinder 20 is detected. The mark detector 26 stores the detected position information in a storage device connected to a control unit that controls the printing apparatus 1. The mark detector 26 is an example of a detection unit. The to-be-printed substrate table 8 is blocked by the 6-axis drive mechanism 81 so that the roller cylinder 20 and the block 9 have a predetermined positional relationship for each block 9 based on the positional information stored in the storage device. Fine-tune the position and orientation of 9. Specifically, the 6-axis drive mechanism 81 of the substrate table 8 to be printed is included in the print pattern formed on the blanket 21 of the roller cylinder 20 at the time of printing based on the positional information stored in the storage device. The position and orientation of the block 9 are finely adjusted for each block 9 so that the alignment mark and the alignment mark provided on the block 9 overlap in the same direction. In the present embodiment, the direction includes an inclination.

  The operation of each unit of the printing apparatus 1 is controlled in an integrated manner by a control device (not shown). The control device has a processor such as a CPU (Central Processing Unit). A storage device and a user interface such as a keyboard and a display are connected to the control device.

  The storage device stores a control program for realizing various processes executed by the printing apparatus 1 and data such as position information detected by the mark detector 26 for each block 9. The control device reads out and executes the control program stored in the storage device, thereby causing the printing device 1 to print a predetermined printing pattern on each block 9 in the printed substrate unit 10.

[Operation of Printing Apparatus 1]
Next, the operation of the printing apparatus 1 in the present embodiment will be described with reference to FIGS. 4 and 5. FIG. 4 is a schematic cross-sectional view for explaining an example of the operation of the printing apparatus 1. FIG. 5 is a flowchart illustrating an example of the operation of the printing apparatus 1 according to the first embodiment.

  First, the linear motor 4 and the linear motor 7 move the printed substrate table 8 to a predetermined initial position. Then, the substrate unit 10 to be printed is placed and fixed on the substrate table 8 to be printed by a robot arm (not shown) (S100). The linear motor 14 and the linear motor 16 move the plate table 17 to a predetermined initial position. Then, the plate unit 19 is placed on the plate table 17 and fixed by a robot arm (not shown) (S101).

  Next, the linear motor 4 and the linear motor 7 move the printed substrate table 8 below the mark detector 26. The mark detector 26 reads the alignment mark 90 provided on the block 9 for each block 9 in the substrate unit 10 to be printed (S102). The mark detector 26 detects position information indicating the position and orientation of each block with respect to the roller cylinder 20 based on the read position and orientation of the alignment mark 90. The position information detected by the mark detector 26 is stored in the storage device for each block (S103).

  Next, a variable N for counting the number of blocks is initialized to 1 (S104). Then, the 6-axis drive mechanism 81 of the printed substrate table 8 positions the N-th block in the printed substrate unit 10 below the blanket 21 based on the positional information stored in the storage device. Then, the position and orientation of the block are finely adjusted so that the block and the roller cylinder 20 are in a predetermined positional relationship (S105).

  Next, the vertical mechanisms 23 a and 23 b raise the roller body 20. Then, the rotation mechanism 24 rotates the roller cylinder 20 around the rotation axis RC, and returns the rotation position of the roller cylinder 20 to a predetermined initial position. Then, the coater 25 is brought close to the blanket 21 by a moving mechanism (not shown) until the distance between the tip of the nozzle of the coater 25 and the surface of the blanket 21 becomes a predetermined distance. For example, as shown in FIG. 4A, the rotating mechanism 24 rotates the roller cylinder 20 from the initial position, and ink is ejected from the coater 25, so that a predetermined area on the surface of the blanket 21 is constant. The ink film 30 having a film thickness is formed (S106). After the ink film 30 is formed in a predetermined region on the surface of the blanket 21, the coater 25 is retracted to a predetermined retracted position, and the rotating mechanism 24 rotates the roller cylinder 20 to set the rotational position of the roller cylinder 20 to a predetermined position. Return to the position.

  Next, the vertical mechanisms 23a and 23b lower the roller cylinder 20 to the printing position. The linear motor 14 and the linear motor 16 move the plate table 17 so that one unused printing plate 18 in the plate unit 19 is positioned below the blanket 21 (S107).

  Next, the rotation mechanism 24 rotates the roller cylinder 20 in conjunction with the movement of the plate table 17 in the X-axis direction by the linear motor 14. The speed of the outermost periphery of the roller cylinder 20 by the rotation coincides with the moving speed of the plate table 17 in the X-axis direction. For this reason, for example, as shown in FIG. 4B, the printing plate 18 on the plate table 17 has a blanket 21 on the surface of the printing plate 18 by a convex portion 181 in a region in contact with the blanket 21 substantially linearly. It moves in the direction of the X axis while stripping ink from the ink film 30 formed on the surface. As a result, a printing pattern is formed on the surface of the water-repellent blanket 21 in which the ink film 30 remains in a region corresponding to the concave portion 180 of the printing plate 18 (S108).

  Next, the vertical mechanisms 23a and 23b raise the roller body 20 to a predetermined retracted position. The rotation mechanism 24 rotates the roller cylinder 20 and returns the rotation position of the roller cylinder 20 to a predetermined position. Further, the linear motor 14 moves the plate table 17 to a predetermined retreat position.

  Next, the vertical mechanisms 23a and 23b lower the roller cylinder 20 to the printing position. Further, the linear motor 4 and the linear motor 7 move the printed substrate table 8 so that the Nth block in the printed substrate unit 10 is positioned below the blanket 21 (S109).

  Next, the rotation mechanism 24 rotates the roller cylinder 20 in conjunction with the movement of the printed substrate table 8 in the X-axis direction by the linear motor 4. The speed of the outermost periphery of the roller cylinder 20 due to the rotation coincides with the moving speed of the printed substrate table 8 in the X-axis direction. For this reason, for example, as shown in FIG. 4C, the print pattern formed on the surface of the blanket 21 due to the remaining ink film 30 is transferred onto the Nth block 9 (S110).

Next, the printing apparatus 1 determines whether or not the variable N has reached a predetermined value N ₀ indicating the number of blocks 9 arranged in the printed substrate unit 10 (S111). If the variable N has not reached the predetermined value N ₀ (S111: No), the printing device 1 retracts the substrate to be printed table 8 to a predetermined retracted position by a linear motor 4 (S112). Then, the printing apparatus 1 increases the variable N by 1 (S113). Then, the 6-axis drive mechanism 81 of the printed substrate table 8 executes the process shown in step S105 again.

On the other hand, if the variable N has reached the predetermined value N ₀ (S111: Yes), the linear motor 4 moves the substrate to be printed table 8 to the initial position. Then, the substrate unit 10 to be printed is unloaded from the substrate table 8 to be printed by a robot arm (not shown) (S114). Then, the printing apparatus 1 ends the operation shown in this flowchart.

  Here, when the plurality of blocks 9 are hardened with a resin or the like to form the substrate unit 10 to be printed, in the process of forming the substrate unit 10 to be printed, a positional shift when placing each block 9, A position shift of the block 9 accompanying the flow occurs. Thereby, the position and orientation of each block 9 in the substrate unit 10 to be printed after the resin or the like is cured may deviate from the design value as shown in FIG. 6, for example. When a plurality of blocks 9 whose positions and orientations deviate from the design values are collectively printed on the plurality of blocks 9 using a print pattern that assumes the arrangement of the blocks 9 according to the design values, A print pattern shifted from a desired position is printed. As the pattern formed by printing becomes finer, the deviation of the printed pattern cannot be ignored.

  On the other hand, in the printing apparatus 1 according to the present embodiment, the blanket 21 and the block 9 are finely adjusted so as to have a predetermined positional relationship for each block 9 in the substrate unit 10 to be printed. The printed pattern is printed on the block 9. As a result, for example, as shown in FIG. 7, a printing pattern 91 can be printed with high accuracy for each block 9 even for a block 9 whose position and orientation are deviated from design values. Therefore, the printing apparatus 1 of the present embodiment can print a finer pattern on each block 9 with higher accuracy. Each block 9 may be printed with a plurality of inks having the same or different print patterns. Thereby, a structure with a predetermined thickness can be formed with high accuracy for each block 9.

While the printing process is being performed on the block in one of the two substrate units 10a and 10b, the position information of the other substrate unit is read. Done. The printing process includes, for example, a process for forming an ink film on the surface of the blanket 21, a process for forming the ink film on the surface of the blanket 21 into a printing pattern, and a process for transferring the printing pattern on the surface of the blanket 21 to a block. This process is repeatedly executed for each block in the unit 10.

  The printing apparatus 1 of this modification is provided with a base 5a and a base 5b, and the base 13 is disposed between the base 5a and the base 5b in the X-axis direction. A printed substrate table 8a is provided on the base 5a, and a printed substrate table 8b is provided on the base 5b. A printed substrate unit 10a in which a plurality of blocks 9a are arranged is placed on the printed substrate table 8a, and a printed substrate unit 10b in which a plurality of blocks 9b is arranged on the printed substrate table 8b. Placed. The printing apparatus 1 of the present modification is provided with mark detectors 26a and 26b. The position information of each block 9a in the printed substrate unit 10a is read by the mark detector 26a, and the position information of each block 9b in the printed substrate unit 10b is read by the mark detector 26b.

  In this modification, the base 13 and the printed substrate table 8b can be retracted while the printing process is being performed on the block 9a on the printed substrate table 8a, and the block 9b on the printed substrate table 8b can be retracted. On the other hand, the main body 2 is configured to be longer than the main body 2 of the printing apparatus 1 according to the first embodiment so that the base 13 and the printed substrate table 8a can be retracted while the printing process is being performed.

[Operation of Printing Apparatus 1]
Next, the operation of the printing apparatus 1 configured as shown in FIG. 8 will be described. First, the base 5b is moved to the retracted position by the linear motor 4b. Then, similarly to the printing operation in the first embodiment, for each block 9a in the substrate unit 10a to be printed, formation of a printing pattern on the blanket 21 by the printing plate 18 moved to a position below the roller cylinder 20, Transfer of the printing pattern to the block 9a in the substrate unit 10a that has been moved to a position below the roller cylinder 20 is performed alternately.

  On the other hand, the printed substrate unit 10b is placed and fixed by the robot arm (not shown) on the printed substrate table 8b on the base 5b moved to the retreat space by the linear motor 4b. Then, while the print pattern is transferred to each block 9a in the printed substrate unit 10a, the position information of each block 9b in the printed substrate unit 10b is read by the mark detector 26b. The position information of each block 9b in the printed substrate unit 10b read by the mark detector 26b is stored in the storage device.

  Then, when the transfer of the printing pattern to each block 9a in the printed substrate unit 10a is completed, the base 5a is moved to the initial position by the linear motor 4a, and the printed substrate unit 10a is moved by the robot arm (not shown). The printed board table 8a is unloaded, and another printed board unit 10a is placed and fixed on the printed board table 8a. As for the printed substrate unit 10b, as in the printing operation in the first embodiment, the blanket 21 by the printing plate 18 moved to a position below the roller cylinder 20 for each block 9b in the printed substrate unit 10b. The formation of the print pattern on the substrate and the transfer of the print pattern to the block 9b in the substrate unit 10b that has been moved to a position below the roller cylinder 20 are alternately performed.

  As described above, by performing printing on the printing substrate in each printing substrate unit using the two printing substrate tables 8a and 8b and the one plate table 17, positional information on each printing substrate.

As a result, the printing apparatus 1 according to the present modification can perform printing of the printing pattern on each substrate to be printed with high accuracy and can improve the throughput of the printing process.

<Second Embodiment>
Next, the printing apparatus 1 according to the second embodiment will be described. In the printing apparatus 1 according to the present embodiment, ink is supplied to the surface of the blanket 21 of the roller cylinder 20 by a rotary screen method. This eliminates the need for processing such as washing of the printing plate and cleaning of the blanket 21 required for each printing in the reverse printing method, or processing for each printing from several tens to several hundreds of times. Therefore, the operating rate of the printing apparatus 1 can be increased. In addition, since the frequency of processing such as cleaning of the printing plate and cleaning of the blanket 21 can be reduced, the amount of ink to be discarded can be reduced, and the use efficiency of ink can be increased.

  FIG. 9 is a perspective view illustrating an example of the configuration of the printing apparatus 1 according to the second embodiment. Except for the points described below, the configuration denoted by the same reference numerals as those in FIG. 1 in FIG. 9 has the same or similar functions as the configuration described with reference to FIG.

  A substantially cylindrical stencil type screen plate 40 is provided on the upper portion of the roller cylinder 20. The screen plate 40 has an opening corresponding to the printing pattern, and the ink supplied into the screen plate 40 is pushed out by the squeegee 41 through the opening. As a result, the ink film 30 is formed on the surface of the blanket 21 in the shape of a print pattern corresponding to the opening. The screen plate 40 is an example of a print pattern forming unit. The width of the screen plate 40 in the Y-axis direction corresponds to the width of the blanket 21 and the width of the block 9 in the Y-axis direction (that is, the width of one block in the Y-axis direction). For example, the width of the screen plate 40 in the Y-axis direction is the same length as the width of the blanket 21 in the Y-axis direction and the width of the block 9 (that is, the width of one block in the Y-axis direction).

[Operation of Printing Apparatus 1]
Next, the operation of the printing apparatus 1 configured as shown in FIG. 9 will be described with reference to FIG. FIG. 10 is a schematic diagram for explaining an example of a printing pattern forming process according to the second embodiment. First, the printed substrate table 8 is moved to a predetermined initial position, and the printed substrate unit 10 is placed on the printed substrate table 8 and fixed by a robot arm (not shown). Then, the printed substrate table 8 is moved below the mark detector 26, and the alignment mark 90 is read by the mark detector 26 for each block 9 in the printed substrate unit 10. And the positional information detected based on the read alignment mark 90 is preserve | saved for every block at a memory | storage device.

  Next, the 6-axis drive mechanism 81 of the substrate table 8 to be printed is positioned below the blanket 21 with respect to one block in the substrate unit 10 to be printed based on the position information stored in the storage device. Then, the position and orientation of the block are finely adjusted so that the block and the roller cylinder 20 have a predetermined positional relationship.

  Next, the vertical mechanisms 23 a and 23 b raise the roller body 20. Then, the rotation mechanism 24 rotates the roller cylinder 20 around the rotation axis RC, and returns the rotation position of the roller cylinder 20 to a predetermined initial position. Then, the vertical mechanisms 23a and 23b raise the roller cylinder 20 so that the distance between the screen plate 40 and the surface of the blanket 21 becomes a predetermined distance as shown in FIG. 10A, for example. The rotation mechanism 24 rotates the roller cylinder 20 from the initial position, and the screen plate 40 rotates in accordance with the rotation of the roller cylinder 20. Accordingly, for example, as shown in FIG. 10B, the ink in the screen plate 40 is pushed out by the squeegee 41 from the opening corresponding to the printing pattern. As a result, an ink film 30 having a certain thickness corresponding to the print pattern is formed in a predetermined region on the surface of the blanket 21. After the ink film 30 corresponding to the print pattern is formed in a predetermined region on the surface of the blanket 21, the vertical mechanisms 23a and 23b lower the roller cylinder 20 to a predetermined standby position. Then, the rotating mechanism 24 rotates the roller cylinder 20 and returns the rotation position of the roller cylinder 20 to a predetermined position.

  Next, the vertical mechanisms 23a and 23b lower the roller cylinder 20 to the printing position. Further, the linear motor 4 and the linear motor 7 are the printed substrate table 8 so that the block in which the position and orientation are finely adjusted is positioned below the blanket 21 among the blocks in the printed substrate unit 10. Move.

  Next, the rotation mechanism 24 rotates the roller cylinder 20 in conjunction with the movement of the printed substrate table 8 in the X-axis direction by the linear motor 4. Since the speed of the outermost circumference of the roller cylinder 20 due to the rotation and the moving speed of the substrate table 8 to be printed in the X-axis direction match, for example, as shown in FIG. 4C, the ink film 30 remains. Thus, the print pattern formed on the surface of the blanket 21 is transferred onto the block 9.

  The above processing is executed for each block 9 in the substrate unit 10 to be printed. As a result, the printing apparatus 1 according to the present embodiment is configured so that the blocks 9 on the substrate unit 10 to be printed are in the positions and orientations deviated from the positions and orientations as designed. A printing pattern can be printed with high accuracy. Furthermore, the printing apparatus 1 according to the present embodiment executes the formation of a printing pattern on the surface of the blanket 21 by a rotary screen method. This eliminates the need for processing such as washing of the printing plate and cleaning of the blanket 21 required for each printing in the reverse printing method, or processing for each printing from several tens to several hundreds of times. Therefore, the operating rate of the printing apparatus 1 can be increased. In addition, since the frequency of processing such as cleaning of the printing plate and cleaning of the blanket 21 can be reduced, the amount of ink to be exhausted can be reduced, and ink use efficiency can be increased.

<Modification of Second Embodiment>
Next, a modified example of the printing apparatus 1 according to the second embodiment will be described. FIG. 11 is a perspective view showing a modification of the printing apparatus 1 according to the second embodiment. FIG. 12 is a schematic top view illustrating a modification of the printing apparatus 1 according to the second embodiment. FIG. 12 shows an upper surface of a portion of the printing apparatus 1 excluding the bracket 22, the vertical mechanism 23a, the vertical mechanism 23b, the rotating mechanism 24, the screen plate 40, and the like.

In the following description, the printed substrate table 8a may be referred to as table A, and the printed substrate table 8b may be referred to as table B.

[Operation of Printing Apparatus 1]
Next, the operation of a modified example of the printing apparatus 1 according to the present embodiment will be described with reference to FIGS. 13 and 14. FIG. 13 and FIG. 14 are flowcharts illustrating an example of the operation of a modified example of the printing apparatus 1 according to the second embodiment.

  First, the linear motor 4a and the linear motor 7a move the table A to a predetermined initial position. Then, the substrate unit 10a to be printed is placed and fixed on the table A by the robot arm 50a shown in FIG. 12 (S200).

  Next, the linear motor 4a and the linear motor 7a move the table A below the mark detector 26a. The mark detector 26a reads the alignment mark 90 provided in the block 9a for each block 9a in the substrate unit 10a to be printed (S201). Then, the mark detector 26 a detects position information indicating the position and orientation of each block with respect to the roller cylinder 20 based on the read position and orientation of the alignment mark 90. The position information detected by the mark detector 26a is stored in the storage device for each block (S202).

  Next, the linear motor 4b and the linear motor 7b move the table B to a predetermined initial position. Then, the substrate unit 10b to be printed is placed on the table B and fixed by the robot arm 50b shown in FIG. 12 (S203).

  Next, a printing process is performed on the substrate unit 10a on the table A (S204). In step S204, the following printing process is executed for each block in the printed substrate unit 10a. That is, the six-axis drive mechanism 81a of the table A is configured so that when each block in the printed substrate unit 10a is positioned below the blanket 21 based on the position information stored in the storage device, the block The position and orientation of the block are finely adjusted so that the roller cylinder 20 and the roller cylinder 20 have a predetermined positional relationship. Next, the vertical mechanisms 23a and 23b raise the roller cylinder 20 so that the distance between the screen plate 40 and the surface of the blanket 21 is a predetermined distance. The rotation mechanism 24 rotates the roller cylinder 20 from the initial position, and the screen plate 40 rotates in accordance with the rotation of the roller cylinder 20. As a result, the ink in the screen plate 40 is pushed out from the opening corresponding to the printing pattern by the squeegee 41, and an ink film 30 having a certain film thickness corresponding to the printing pattern is formed in a predetermined region on the surface of the blanket 21. . The vertical mechanisms 23a and 23b lower the roller cylinder 20 to a predetermined standby position, and the rotation mechanism 24 rotates the roller cylinder 20 to return the rotation position of the roller cylinder 20 to the predetermined position. Then, the vertical mechanisms 23a and 23b lower the roller cylinder 20 to the printing position. Further, the linear motor 4a and the linear motor 7a move the table A so that the block whose position and orientation are finely adjusted is positioned below the blanket 21 among the blocks in the substrate unit 10a to be printed. . The rotating mechanism 24 rotates the roller cylinder 20 in conjunction with the movement of the table A in the X-axis direction by the linear motor 4a. Thereby, the printing pattern formed on the surface of the blanket 21 is transferred onto the block in the substrate unit 10a to be printed.

  After the process of step S204 is completed, the linear motor 4a and the linear motor 7a move the table A to a predetermined initial position (S205). Then, the substrate unit 10a to be printed is unloaded from the table A by the robot arm 50a (S206).

  On the other hand, in parallel with the execution of step S204, the linear motor 4b and the linear motor 7b move the table B below the mark detector 26b. The mark detector 26b reads the alignment mark 90 provided on the block 9b for each block 9b in the substrate unit 10b to be printed (S207). Then, the mark detector 26 b detects position information indicating the position and orientation of each block with respect to the roller cylinder 20 based on the read position and orientation of the alignment mark 90. The position information detected by the mark detector 26b is stored in the storage device for each block (S208).

  Next, it is determined whether an end condition is satisfied (S209). The termination condition is, for example, a condition that printing processing for a predetermined number of substrate units 10a and 10b has been executed. When the predetermined condition is not satisfied (S209: No), another printed substrate unit 10a is placed on the table A and fixed by the robot arm 50a (S210). Then, the linear motor 4a and the linear motor 7a move the table A below the mark detector 26a, and the mark detector 26a reads the alignment mark 90 for each block in the substrate unit 10a to be printed. It is detected (S211). Then, the position information detected by the mark detector 26a is stored in the storage device for each block (S212). Then, after step S214 described later is executed, the process shown in step S204 is executed again.

  On the other hand, in parallel with the execution of the processes shown in steps S210 to S212, the printing process is executed for the substrate unit 10b on the table B (S213). In step S213, the following printing process is executed for each block in the printed substrate unit 10b. That is, the 6-axis drive mechanism 81b of the table B is configured so that when each block in the printed substrate unit 10b is positioned below the blanket 21 based on the position information stored in the storage device, the block The position and orientation of the block are finely adjusted so that the roller cylinder 20 and the roller cylinder 20 have a predetermined positional relationship. Next, the vertical mechanisms 23a and 23b raise the roller cylinder 20 so that the distance between the screen plate 40 and the surface of the blanket 21 is a predetermined distance. The rotation mechanism 24 rotates the roller cylinder 20 from the initial position, and the screen plate 40 rotates in accordance with the rotation of the roller cylinder 20. As a result, the ink in the screen plate 40 is pushed out from the opening corresponding to the printing pattern by the squeegee 41, and an ink film 30 having a certain film thickness corresponding to the printing pattern is formed in a predetermined region on the surface of the blanket 21. . The vertical mechanisms 23a and 23b lower the roller cylinder 20 to a predetermined standby position, and the rotation mechanism 24 rotates the roller cylinder 20 to return the rotation position of the roller cylinder 20 to the predetermined position. Then, the vertical mechanisms 23a and 23b lower the roller cylinder 20 to the printing position. Further, the linear motor 4b and the linear motor 7b move the table B so that the block whose position and orientation are finely adjusted is positioned below the blanket 21 among the blocks in the printed board unit 10b. . The rotating mechanism 24 rotates the roller cylinder 20 in conjunction with the movement of the table B in the X-axis direction by the linear motor 4b. Thereby, the printing pattern formed on the surface of the blanket 21 is transferred onto the block in the substrate unit 10b to be printed.

  After the process of step S213 is completed, the linear motor 4b and the linear motor 7b move the table B to a predetermined initial position (S214). Then, the substrate unit 10b to be printed is unloaded from the table B by the robot arm 50b (S215). Then, another printed substrate unit 10b is placed on the table B and fixed by the robot arm 50b (S216). Then, the process shown in step S207 is executed again.

  On the other hand, when the termination condition is satisfied (S209: Yes), the printing process is executed on the substrate unit 10b on the table B (S217). Since the printing process executed in step S217 is the same as the printing process executed in step S213, description thereof is omitted. After the printing process in step S217 is completed, the linear motor 4b and the linear motor 7b move the table B to a predetermined initial position (S218). Then, the substrate unit 10b to be printed is unloaded from the table B by the robot arm 50b (S219). Then, the printing apparatus 1 ends the operation shown in this flowchart.

  As a result, the printing apparatus 1 according to the present modification can prevent the blocks 9 from being printed even when the positions and orientations of the blocks 9 on the substrate unit 10 are deviated from the positions and orientations as designed. A printing pattern can be printed with high accuracy. Further, in the printing apparatus 1 according to the present modification, a printing pattern is formed on the surface of the blanket 21 by the rotary screen method. Therefore, processing such as cleaning of the printing plate and cleaning of the blanket 21 necessary for each printing by the reverse printing method is performed. Is not necessary, or processing for several tens to several hundreds of printings is sufficient. Therefore, the operating rate of the printing apparatus 1 can be increased.
