Description

  The present invention relates to a printing apparatus and a component mounting substrate manufacturing apparatus.

  Conventionally, printing apparatuses that perform printing by discharging ink are known. For example, in Patent Document 1, a fabric holding frame (stage) that holds a fabric (printing object), a vertically movable print head having a nozzle array, and an outer frame of the fabric holding frame are detachably provided. A printing apparatus including a rectangular ink receiving member that is longer than the length of a nozzle row is disclosed. In this printing apparatus, since the ink receiving member is longer than the length of the nozzle row, it is possible to simultaneously eject ink from all the nozzles in the nozzle row when performing flushing, thereby shortening the flushing time. In the printing apparatus, since the ink receiving member is held on the upper surface side of the fabric holding frame, when flushing, the ink receiving member is simply moved horizontally without moving the print head up and down. The member can be moved to a flushing position corresponding to the print head.

FIG. 3 is an explanatory diagram, and FIG. 3 is an explanatory diagram showing an electrical connection relationship of the control device 70. Note that the front (front) and rear (back) directions in FIG. 1 are the X-axis direction, and the left-right direction is the Y-axis direction.

  As shown in FIG. 1, the component mounting substrate manufacturing apparatus 10 of the present embodiment includes a stage 12, a transfer device 20, a resin layer forming unit 30, a wiring layer forming unit 40, a component mounting unit 50, and a control. Device 70 (see FIG. 3). The resin layer forming unit 30, the wiring layer forming unit 40, and the component mounting unit 50 are installed side by side along the conveyance direction (Y-axis direction) of the stage 12.

  A work table 14 and a flushing box 18 are installed on the stage 12. The work table 14 is a work table used when the resin layer forming unit 30, the wiring layer forming unit 40, and the component mounting unit 50 each perform work. As shown in FIG. 2, the work table 14 is independent of the stage 12 by the table lifting device 16. And can be moved up and down.

  The flushing box 18 is an ink receiver when the resin layer forming unit 30 (ink head 32) and the wiring layer forming unit 40 (ink head 42) perform flushing. As shown in FIG. Installed adjacent to the direction. The height of the flushing box 18 is determined so that the vertical distance from the ink heads 32 and 42 (nozzle surface) is a predetermined distance so that ink mist is not scattered during flushing. Further, the flushing box 18 is detachable from the stage 12, and can be replaced with a new one when the accumulated ink is full.

  As shown in FIG. 1, the conveying device 20 includes a pair of guide rails 22 extending in the Y-axis direction and a belt driving device 24 (see FIG. 3) that drives a timing belt, and is transmitted via the timing belt. The stage 12 can be reciprocated along the guide rail 22 by power.

  The resin layer forming unit 30 is for forming a resin layer on the work table 14 when the stage 12 (work table 14) is being transported into the work area of the resin layer forming unit 30. As shown in FIG. 1, the resin layer forming unit 30 includes an ink head 32 that can eject UV curable resin ink, and a UV light irradiation device that can irradiate the resin ink discharged from the ink head 32 with UV light. 34.

  The ink head 32 is, for example, a line head in which a plurality of nozzles are arranged so as to cover the entire width of the print area on the work table 14. The ink head 32 applies (prints) a rectangular resin layer by discharging resin ink from all the nozzles while the work table 14 is transported in the Y-axis direction by the transport device 20. The ink head 32 performs flushing by ejecting ink from the nozzles while the flushing box 18 is moved directly below the ink head 32 by the transport device 20 immediately before printing is started or during printing.

  The UV light irradiation device 34 is configured to be able to irradiate line-shaped UV light in the X-axis direction. This UV light irradiation device 34 irradiates the rectangular resin layer applied to the work table 14 with line-shaped (X-axis direction) UV light while transporting the work table 14 in the Y-axis direction. The applied resin layers are sequentially cured. For example, a mercury lamp or a metal halide lamp can be used as the UV light irradiation device 34.

  The resin layer forming unit 30 thus repeats the application of the resin layer by the ink head 32 and the curing of the resin layer by the UV light irradiation device 34 a plurality of times, thereby laminating the resin layers, and having a predetermined thickness. A resin base material is produced.

  The wiring layer forming unit 40 forms a wiring layer on the resin layer formed on the work table 14 when the stage 12 (work table 14) is being transported into the work area of the wiring layer forming unit 40. is there. The wiring layer forming unit 40 includes an ink head 42 capable of discharging conductive particle-containing ink in which conductive particles such as metal nanoparticles are dispersed in a dispersant, and conductive particle-containing ink discharged from the ink head 42. And a laser irradiation device 46 that irradiates a laser beam.

  In this embodiment, the ink head 42 is a line head in which a plurality of nozzles are arranged so as to cover the entire width of the print region. The ink head 42 discharges the conductive particle-containing ink from a corresponding nozzle while transporting the work table 14 in the Y-axis direction by the transport device 20, so that the conductive particle-containing ink is placed at an arbitrary position on the resin layer. Apply (print). Specifically, the ink head 42 forms a wiring layer on the resin layer (resin base material) by discharging conductive particle-containing ink from a corresponding nozzle along a predetermined wiring line. Further, the ink head 42 performs flushing by ejecting ink from the nozzle in a state where the flushing box 18 is moved directly below the ink head 42 by the transport device 20 immediately before printing is started or during printing.

  The laser irradiation device 46 is mounted on a carriage 44 that can move in the X-axis direction by driving a carriage motor 45 (see FIG. 3). The laser irradiation device 46 moves in the X-axis direction and the Y-axis of the work table 14. The laser beam is scanned along the planned wiring line (wiring layer) on the resin substrate formed on the work table 14 by the movement in the direction. The wiring layer is made conductive by decomposing the dispersant around the conductive particles by the laser beam.

  The wiring layer forming unit 40 thus repeats the application of the conductive particle-containing ink by the ink head 42 and the conduction of the conductive particle-containing ink by the laser irradiation device 46 a plurality of times, thereby making the wiring layer conductive. Lamination is performed, and a wiring pattern is formed on the resin substrate to produce a wiring substrate.

  The component mounting unit 50 mounts components on the wiring substrate produced on the work table 14 when the stage 12 (work table 14) is being transported into the work area of the component mounting unit 50. The component mounting unit 50 is configured as an articulated robot including an articulated arm 54 in which a plurality of links are connected in series, and a chuck 52 provided at the tip of the articulated arm 54 and capable of gripping the component P. Then, the component P supplied by the component supply device 58 is gripped by the chuck 52 and mounted on the wiring substrate.

  The articulated arm 54 is provided with an arm motor 55 at a connecting part for connecting the links, and by driving the arm motor 55, the tip part can be moved to an arbitrary position in a predetermined space.

  The chuck 52 can be opened and closed (gripping operation) by driving a chuck motor 53 (see FIG. 3). Further, the chuck 52 can be attached to and detached from the tip of the articulated arm 54, and can be exchanged for one that is suitable for the type of gripping object (component P). In the present embodiment, as the chuck 52, a plurality of types corresponding to the size and shape of the component P are prepared, and the flushing box 18 is exchanged by the component mounting unit 50, which is suitable for gripping the flushing box 18. Things are also available. These chucks 52 are housed in a stocker (not shown) and can be automatically replaced by the operation of the articulated arm 54.

  The component mounting unit 50 is configured by an articulated robot. However, the component mounting unit 50 is not limited to this, and any component can be mounted on the wiring substrate by gripping the component P, such as an orthogonal coordinate robot. Any type of robot may be used.

  As shown in FIG. 3, the control device 70 includes a CPU 71, a ROM 72, an HDD 73, a RAM 74, and an input / output interface 75. These are electrically connected via a bus 76. Various detection signals from the position detection sensor for detecting the position of the work table 14 in the Y-axis direction and the position detection sensor for detecting the position of the carriage 44 in the X-axis direction are transmitted to the control device 70 via the input / output interface 75. Have been entered. Further, from the control device 70 to the table elevating device 16, belt driving device 24, ink head 32, UV light irradiation device 34, ink head 42, carriage motor 45, laser irradiation device 46, chuck motor 53, arm motor 55, and the like. The various control signals are output via the input / output interface 75.

  Next, operation | movement of the component mounting base material manufacturing apparatus 10 of the Example comprised in this way is demonstrated. FIG. 3 is a flowchart illustrating an example of a component mounting base material manufacturing process executed by the CPU 71 of the control device 70. This process is executed based on an instruction from the operator.

  When the component mounting substrate manufacturing process is executed, the CPU 71 of the control device 70 first inputs process data that defines the execution order of the resin layer forming step, the wiring layer forming step, and the component mounting step (S100). Is initialized to the value 1 (S110). The process data can be input via an input device (not shown) based on the operator's operation. Next, the CPU 71 determines whether or not the Nth (execution count N) process is a resin layer forming process (S120) and a wiring layer forming process (S130) based on the input process data. Judge each one. If the CPU 71 determines that the Nth step is a resin layer forming step, the CPU 71 executes a resin layer forming process (S140). If the CPU 71 determines that the Nth step is a wiring layer forming step, the CPU 71 executes a wiring layer forming process. (S150). If the CPU 71 determines that the N-th step is neither a resin layer formation step nor a wiring layer formation step, the CPU 71 executes component mounting processing (S160). Then, the CPU 71 determines whether or not the execution number N has reached a predetermined number Nend indicating the end of the process (S170). If the CPU 71 determines that the execution number N has not reached the predetermined number Nend, the CPU 71 increments the execution number N by a value 1 (S180), returns to S120, and executes the next N-th process. If it is determined that the predetermined number of times Nend has been reached, the component mounting base material creation process is ended.

  The resin layer forming step is performed by executing a resin layer forming process illustrated in FIG. In the resin layer forming process of FIG. 5, the CPU 71 first drives and controls the table elevating device 16 to raise and lower the work table 14, so that the interval (head gap) between the printing surface and the ink head 32 (nozzle surface) is ink. Adjustment is made so that the distance between the head 32 (nozzle surface) and the flushing box 18 is substantially the same (S200). As described above, the resin base material is formed by laminating resin layers. For this reason, the printing surface on the work table 14 becomes higher as the lamination of the resin layers proceeds. The process of S200 is performed by lowering the work table 14 as the number of resin layers is increased so that the distance between the printing surface and the ink head 32 is always constant.

  The CPU 71 drives and controls the transport device 20 to move the flushing box 18 directly below the ink head 32 (S210), and performs flushing by ejecting ink from all nozzles of the ink head 32 (S220). The flushing execution count Nf is incremented by 1 (S230). Thus, the CPU 71 performs flushing immediately before the start of printing so that ink can be stably ejected from the nozzles of the ink head 32. The flushing may be performed periodically during printing. As described above, since the interval between the flushing box 18 and the ink head 32 is an interval suitable for flushing, just by moving the stage 12 in the Y-axis direction by the transport device 20, the interval is just below the ink head 32. It can be moved and flushed. The flushing may be executed in parallel with the head gap adjustment in S200.

  Next, the CPU 71 drives and controls the conveying device 20 to move the printing surface to the printing start position (S240), and then starts scanning the printing surface (S250). Then, the CPU 71 drives and controls the ink head 32 so that the resin ink is discharged from all the nozzles while scanning the print surface in the Y-axis direction (S260), and the print surface on which the resin ink is discharged from the UV light irradiation device 34. Is irradiated with UV light (S270), and the resin layer forming process is terminated.

  FIG. 6 is an explanatory view showing the state of the resin layer forming step. In the resin layer forming step, as shown in the figure, before printing the resin ink, the stage 12 is moved in the Y-axis direction to move the flushing box 18 directly below the ink head 32, and all the nozzles of the ink head 32 are moved. Flushing is performed by ejecting ink (see FIG. 6A). The ink head 32 is a line head, and the flushing box 18 is configured to cover the width of the ink head 32 in the X-axis direction. For this reason, the ink head 32 can discharge ink from all the nozzles simultaneously, and can finish flushing in a short time. Then, while moving the stage 12 in the right direction, the resin ink is applied to the printing surface from all the nozzles of the ink head 32, and the applied resin ink is cured by the UV light from the UV light irradiation device 34, thereby the resin. A layer is formed (see FIG. 6B).

  FIG. 7 is an explanatory diagram showing the relationship between the height of the printing surface and the height of the flushing box 18. As shown in the figure, the work table 14 and the flushing box 18 are installed on the stage 12, and both move as the stage 12 moves in the Y-axis direction. As described above, since the height of the printing surface is increased by the ink layer printing, the work table 14 is lowered by the table elevating device 16 so that the distance between the printing surface and the head unit 32 is always kept constant. Is done. On the other hand, the height of the flushing box 18 is fixed so that the distance from the ink head 32 is an appropriate distance for flushing. As a result, the flushing box 18 can be moved directly below the ink head 32 just by transporting the stage 12 when flushing is performed at any timing, and the flushing time can be shortened.

  The wiring layer forming step is performed by executing a wiring layer forming process illustrated in FIG. In the wiring layer forming process of FIG. 8, the CPU 71 first adjusts the head gap (S300), and performs the flushing by moving the flushing box 18 directly below the ink head 42, as in the processes of S200 to S230. The number of executions of flushing Nf is incremented by 1 (S310 to S330).

  Next, after moving the print surface to the print start position (S340), the CPU 71 starts scanning the print surface (S350). Subsequently, the CPU 71 drives and controls the ink head 42 so that the conductive particle-containing ink is ejected from the corresponding nozzle along the planned wiring line while scanning the printing surface in the Y-axis direction (S360). Then, the CPU 71 irradiates a laser beam along the wiring line on which the conductive particle-containing ink is applied (printed) (S370), and the wiring layer forming process is completed. The processing of S370 is performed by scanning the laser irradiation point along the planned wiring line by moving the carriage 44 in the X-axis direction by the carriage motor 45 and moving the work table 14 in the Y-axis direction by the transport device 20. Is called. As a result, the conductive particle-containing ink applied on the resin substrate is made conductive by the decomposition of the dispersant around the conductive particles by the irradiation of the laser beam. In the present embodiment, the conductive particle-containing ink is made conductive using a laser, but may be made conductive using pulsed light, an electric furnace, or the like.

  FIG. 9 is an explanatory diagram showing a state of the wiring layer forming step. Similar to the resin layer forming step, the wiring layer forming step moves the flushing box 18 directly below the ink head 42 by moving the stage 12 in the Y-axis direction before printing the conductive particle-containing ink. Flushing is performed by discharging ink from all nozzles of the head 42 (see FIG. 9A). The flushing box 18 may be provided with a first region that receives the resin ink and a second region that receives the conductive particle-containing ink. In this case, the flushing in the resin layer forming process is performed by moving the stage 12 in the Y-axis direction so that the first region is directly under the ink head 32, and the flushing in the wiring layer forming process is performed directly under the ink head 42. The stage 12 is moved in the Y-axis direction so that the second region comes. Then, while moving the stage 12 in the Y-axis direction, the conductive particle-containing ink is ejected along a predetermined wiring line on the resin substrate by discharging the conductive particle-containing ink from the predetermined nozzle at a predetermined timing. Is applied (printed) (see FIG. 9B). When the conductive containing ink is discharged, the stage 12 is moved in the Y-axis direction and the carriage 44 is moved in the X-axis direction, and the conductive light-containing ink is made conductive by irradiating laser light along the planned wiring line. (See FIG. 9C), a wiring layer is formed.

  The component mounting process is performed by executing the component mounting process of FIG. When the component mounting process of FIG. 10 is executed, the CPU 71 first drives and controls the arm motor 55 so that the chuck 52 moves directly above the component supply position of the component supply device 18, and the component P at the component supply position is moved. The drive of the chuck motor 53 is controlled so as to be gripped by the chuck 52 (S400). Subsequently, the CPU 71 drives and controls the arm motor 55 and the chuck motor 53 so that the component P gripped by the chuck 52 is mounted at the mounting position of the wiring substrate (S410). Then, it is determined whether or not all the components P have been mounted on the wiring base material on the work table 14 (S420). If it is determined that all the components P have not been mounted, the process returns to S400. The mounting of the component P is repeated.

  When the CPU 71 determines that all the components P have been mounted, the CPU 71 determines whether or not the flushing execution count Nf exceeds a threshold value (S430). Here, the threshold value is a threshold value for determining whether or not the ink accumulated in the flushing box 18 is nearly full. In the process of S430, when the flushing is performed in different areas (the above-described first area and second area) in the ink head 32 and the ink head 42, the number of times of performing the flushing is managed for each area. And the number of executions of each can be compared with a threshold value. If the CPU 71 determines that the flushing execution count Nf does not exceed the threshold value, the component mounting process is terminated. On the other hand, when the CPU 71 determines that the number of times of flushing Nf has exceeded the threshold value, it replaces the chuck 52 with one suitable for replacement of the flushing box 18 (S440), and uses the replaced chuck 52 to replace the flushing box 18 Replace with a new one (S450). When the replacement of the flushing box 18 is completed, the CPU 71 resets the flushing execution count Nf to 0 (S460), and ends the component mounting process. Here, in S450, the flushing box 18 on the stage 12 is gripped by the chuck 52 and moved from the stage 12 to an empty space in a box accommodation area (not shown), and then a new flushing accommodated in the box accommodation area is performed. This is done by holding the box 18 with the chuck 52 and moving it from the box accommodation area onto the stage 12.

  FIG. 11 is an explanatory diagram showing the state of the component mounting process. The component mounting process is performed by holding the component P with the chuck 52, moving the component P to the mounting position of the wiring substrate fabricated on the work table 14, and releasing the chuck 52 (see FIG. 11A). ). Thereafter, when the number of times of flushing Nf exceeds the threshold value, the flushing box 18 installed on the stage 12 is gripped by the chuck 52 and moved to an empty space in the box accommodation area and accommodated in the box accommodation area. The new flushing box 18 is gripped by the chuck 52 and moved onto the stage 12, whereby the flushing box 18 is automatically replaced by the component mounting unit 50 (see FIG. 11B).

  Here, the correspondence between the main elements of the present embodiment and the main elements of the invention described in the disclosure section of the invention will be described. That is, the ink heads 32 and 42 of the present embodiment correspond to the heads of the present invention, the work table 14 or the resin layer (resin base material) or the like corresponds to the printing object, the stage 12 corresponds to the stage, and the conveying device. 20 corresponds to a horizontal movement device, the table elevating device 16 corresponds to a vertical movement device, the flushing box 18 corresponds to an ink receiving member, and executes the resin layer forming process of FIG. 5 and the wiring layer forming process of FIG. The CPU 71 of the control device 70 corresponds to the control means. The component mounting unit 50 corresponds to a mounting robot.

  The component mounting substrate manufacturing apparatus 10 of the present embodiment described above includes a stage 12 that can move in the Y-axis direction, a work table 14 that is installed on the stage 12 and can be moved up and down independently of the stage 12, and work On the table 14, a resin layer forming unit 30 (ink head 32) and a wiring layer forming unit 40 (ink head 42) capable of ink layer printing are provided. Further, the component mounting substrate manufacturing apparatus 10 installs a flushing box 18 adjacent to the work table 14 on the stage 12. Thereby, the space | interval of a printing surface and the ink heads 32 and 42 can be maintained at a fixed space | interval according to progress of lamination | stacking printing, and the fall of print quality can be suppressed. In addition, since the interval between the ink heads 32 and 42 and the flushing box 18 can always be an interval suitable for flushing, flushing can be performed more efficiently.

  Moreover, since the component mounting substrate manufacturing apparatus 10 of the present embodiment enables the flushing box 18 to be attached to and detached from the stage 12, and the flushing box 18 is automatically replaced by the component mounting unit 50, the burden on the operator is reduced. Can do. In addition, since it is not necessary to install a dedicated robot for replacing the flushing box 18, the apparatus can be simplified and downsized.

  It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that the present invention can be implemented in various modes as long as it belongs to the technical scope of the present invention.

  For example, in the above-described embodiment, printing is performed by ejecting ink from the ink heads 32 and 42 while transporting the work table 14 in the Y-axis direction, but the forward and backward movements of the work table 14 are performed. Printing may be executed in either direction. In this case, the flushing box 18 may be installed on both sides of the work table 14 in the Y-axis direction. Thus, the flushing time can be further shortened by performing flushing on the nearer flushing box during forward printing and backward printing.

  In the above-described embodiment, the work table 14 is configured to be movable up and down independently of the stage 12, and the ink heads 32 and 42 and the flushing box 18 are configured to be unable to move up and down. However, the present invention is not limited to this. For example, as shown in FIG. 12, the work table 14 may be configured so as not to be raised and lowered, and the ink heads 32 and 42 and the flushing box 18 may be configured to be raised and lowered. The component mounting substrate manufacturing apparatus according to this modification includes a head lifting device 33 for lifting the ink head 32 and a box lifting device 19 for lifting the flushing box 18 instead of the table lifting device 16. The adjustment of the head gap (S200 in the resin layer forming step) is performed by driving and controlling the head lifting device 33 so that the ink head 32 is raised and lowered so that the distance between the printing surface and the ink head 32 is a predetermined interval. Further, in the flushing (resin layer forming step S210, S220), the box lifting device 19 is driven and controlled so that the ink head 32 moves up and down so that the distance between the ink head 32 and the flushing box 18 is kept constant. At the same time, the flushing box 18 is moved up and down. A similar head lifting device can be provided for the ink head 42.

  In the above-described embodiment, the flushing is performed by the resin layer forming unit 30 and the wiring layer forming unit 40. However, the flushing may be performed by only one of the units.

  In the above-described embodiment, the flushing box 18 can be automatically replaced by the component mounting unit 50. However, a dedicated robot for automatically replacing the flushing box 18 may be provided. The operator may replace the flushing box 18 manually.

  In the above-described embodiment, the flushing box 18 can be attached to and detached from the stage 12. However, for example, the flushing box 18 may not be attached or detached. In this case, a collection device that automatically collects ink collected in the flushing box 18 by sucking with a pump may be provided.

  In the above-described embodiment, the present invention is applied to the component mounting substrate manufacturing apparatus 10 including the resin layer forming unit 30, the wiring layer forming unit 40, and the component mounting unit 50. The present invention may be applied to a device that does not include the wiring layer forming unit 40, or may be applied to a device that does not include the wiring layer forming unit 40. In other words, the present invention may be in the form of a printing apparatus capable of ink layer printing.

  The present invention can be used in the manufacturing industry of printing apparatuses.
