Description

  The present invention relates to a droplet discharge recording apparatus, a droplet discharge recording method, and a control program for the droplet discharge recording apparatus, and more particularly to uniformization of ink landing positions.

  In recent years, a technique called three-dimensional molding has been used in the field of rapid prototyping and the like. The three-dimensional object obtained by such three-dimensional molding is often used as a prototype or an exhibition for evaluating the appearance and performance of the final product in the product development stage.

  As such a three-dimensional molding technique, a method is used in which a three-dimensional object is interpreted as a layered body of layers perpendicular to the vertical direction, and a layer formed by ejecting a molding material by an ink jet method is laminated. (For example, refer to Patent Document 1). In addition, in the inkjet method, a multi-pass method in which ejection for forming one pixel is divided into a plurality of times may be used in order to disperse the deviation of the ink landing positions (see, for example, Patent Document 2). ).

  In the ink jet system, an error may occur in the ink landing position, for example, when deviation occurs in the ink ejection direction or when the base feed amount for moving the ink landing position varies. In contrast to this, by performing the ejection for forming one pixel by using the multi-pass method disclosed in Patent Document 2 in a plurality of times, the above-described error is dispersed, so that an overall error is obtained. Can obtain a uniform output result.

  However, when the multi-pass method is used, since one pixel is formed by a plurality of ejections, it takes time and productivity is reduced as compared to the case where one pixel is formed by one ejection. In particular, in three-dimensional modeling in which a three-dimensional object is formed by laminating planar output results, a decrease in productivity due to multipass becomes more remarkable.

  Note that the decrease in productivity due to the use of the multi-pass method is particularly noticeable in the case of three-dimensional modeling as described above, but the same problem occurs when a flat image or an image having irregularities is formed by an inkjet printer. It becomes. That is, a similar problem occurs in a droplet discharge recording apparatus that records by discharging droplets.

  The present invention has been made to solve such a problem, and in an apparatus for performing recording by ejecting droplets, deviation in landing positions of the ejected droplets can be achieved without reducing productivity. The purpose is to eliminate.

In order to solve the above-described problems, an aspect of the present invention is a droplet discharge recording apparatus that records at least a planar shape by discharging droplets, and is a recording table that serves as a base on which the droplets are discharged A droplet discharge unit that discharges the droplets to the recording table, and a vibration exciter that vibrates the recording table. A first vibration, which is a vibration in two directions perpendicular to each other and perpendicular to the ejection direction in which the droplet is ejected , is applied to the recording table before landing on the recording table. .

  According to the present invention, in an apparatus that performs recording by discharging droplets, it is possible to eliminate the uneven landing position of the discharged droplets without reducing productivity.

In the present embodiment, 3D data indicating the shape of a three-dimensional object such as CAD (Computer Aided Design) data is received, and a layer formed by ejecting a molding material by a head that ejects droplets based on the data is laminated. A 3D printer, which is a droplet discharge recording apparatus that forms a three-dimensional object by doing so, will be described as an example.

  FIG. 1 is a perspective view showing an external configuration of a 3D printer 1 according to the present embodiment. As shown in FIG. 1, the 3D printer 1 according to the present embodiment includes a carriage 101, a guide rail 102, a recording table 103, an X direction shaker 104, a Y direction shaker 105, and a Z direction shaker 106. .

  As shown in FIG. 2, the carriage 101 is mounted with heads 101 a to 101 d that are droplet discharge units for discharging a molding material and light sources 101 e and 101 f for exposing the discharged molding material. The carriage 101 according to the present embodiment discharges a molding material while moving in the X direction shown in FIG. At that time, light sources 101e and 101f are provided at both ends in the X direction so as to be able to cope with both cases of the forward path and the return path.

  The 3D printer 1 according to the present embodiment forms a three-dimensional modeled object on the recording table 103 by exposing the photocurable resin discharged from the head with light irradiated from a light source. The material used by the 3D printer 1 may be a material other than resin as long as it is a photo-curing material. The guide rail 102 supports the carriage 101 and serves as a guide when the carriage 101 is moved in the X direction in the drawing. The recording table 103 is a base for stacking molding materials to form a three-dimensional object.

  The X direction shaker 104, the Y direction shaker 105, and the Z direction shaker 106 are shakers for vibrating the recording table 103 in the X direction, the Y direction, and the Z direction, respectively. The 3D printer 1 according to the present embodiment is characterized in that the recording table 103 vibrates in each direction by these vibrators. Details will be described later.

  The 3D printer 1 discharges the molding material from the heads 101a to 101d in accordance with the circular slice image generated by horizontally cutting the three-dimensional modeled object determined by the 3D data, and the discharged molding material is used as the light source 101e. 101f is exposed and cured to form a layer, and three-dimensional modeling is performed by stacking such layers.

  Next, the functional configuration of the 3D printer 1 according to the present embodiment will be described with reference to FIG. As shown in FIG. 3, the 3D printer 1 according to the present embodiment includes the carriage 101, the recording table 103, the X direction shaker 104, the Y direction shaker 105, and the Z direction shaker 106 described in FIG. 1. In addition, a controller 100, an operation panel 130, a main scanning motor 140 and a sub scanning motor 150 are included.

  The operation panel 130 is a user interface that functions as an operation unit and a display unit for inputting and displaying information necessary for the 3D printer 1. The carriage 101 is the same as that described with reference to FIG. 1, and a print head for discharging a molding material is mounted on the surface of the paper, and is moved in the main scanning direction, which is the X direction in FIG.

  The main scanning motor 140 is a motor that supplies power for moving the carriage 101 in the main scanning direction. The sub-scanning motor 150 is a motor that supplies power for transporting the recording table 103 in the sub-scanning direction that is the Y direction in FIG.

  The controller 100 is a control unit that controls the operation of the 3D printer 1 and has a calculation function similar to that of the information processing apparatus as shown in FIG. Specifically, the controller 100 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a NVRAM (Non Volatile RAM) 14, and an ASIC (Application Specific 15). It includes an I / F 17, a DAC (Digital Analogue Converter) 18, a head driving unit 19, a light source driving unit 20, a main scanning motor driving unit 21, a sub-scanning motor driving unit 22, and a pressure mechanism piezoelectric element driving unit 23.

  The CPU 11 is a calculation means and controls the operation of each part of the controller 100. The ROM 12 is a read-only nonvolatile storage medium, and stores programs such as firmware. The RAM 13 is a volatile storage medium capable of reading and writing information at high speed, and is used as a work area when the CPU 11 processes information. The NVRAM 14 is a nonvolatile storage medium capable of reading and writing information, and stores a control program and control parameters.

  The ASIC 15 is a hardware circuit that executes image processing necessary for image formation output. The host I / F 17 is an interface for receiving 3D data from a host device such as a PC (Personal Computer), and uses an Ethernet (registered trademark) or a USB (Universal Serial Bus) interface.

  The DAC 18 converts the digital information into an analog signal, and generates an analog signal for causing the heads 101a to 101d to discharge the molding material. The head drive unit 19 inputs the analog signal converted by the DAC 18 to the carriage 101 and drives the heads 101a to 101f. The head drive unit 19 includes a drive circuit for selectively driving a plurality of nozzles included in the heads 101a to 101d in addition to the voltage amplification function and the current amplification function.

  The light source drive unit 20 drives the light sources 101e and 101f to emit light in order to cure the molding material discharged from the heads 101a to 101d under the control of the CPU 11. The main scanning motor driving unit 21 and the sub scanning motor driving unit 22 respectively drive the main scanning motor 140 and the sub scanning motor 150 according to the control of the CPU 11. The pressurizing mechanism piezoelectric element driving unit 23 drives the X-direction vibrator 104, the Y-direction vibrator 105, and the Z-direction vibrator 106 according to the control of the CPU 11 to vibrate the recording table 103 in each direction.

  The 3D data indicating the shape of the three-dimensional structure is received by the host I / F 17. The CPU 11 reads and analyzes 3D data in the reception buffer included in the host I / F 17 and controls the ASIC 15 to execute image processing, data rearrangement processing, and the like necessary for 3D modeling output. By the processing by the ASIC 15, ring cut data in which the three-dimensional model is cut into pieces is generated. The cut data is transferred by the CPU 11 to the head driving unit 19 and the light source driving unit 20 for each main scanning line.

  When the head drive unit 19 receives data (dot pattern data) corresponding to one line of the ring cutting data in the main scanning direction, the dot pattern data for one line is serially transmitted to the carriage 101 in synchronization with the clock signal. And a latch signal is sent to the carriage 101 at a predetermined timing.

  The DAC 18 reads pattern data of a drive waveform (head drive signal) stored in the ROM 12, performs D / A conversion to generate a drive waveform of an analog signal, and inputs it to the head drive unit 19. The head drive unit 19 inputs the drive waveform input from the DAC 18 to the carriage 101.

  The carriage 101 includes a shift register that holds a clock signal and serial data input from the head driving unit 19, a latch circuit that latches a register value of the shift register with a latch signal from the head driving unit 19, and an output value of the latch circuit A level conversion circuit (level shifter) for changing the level of the signal, an analog switch array (switch means) whose on / off is controlled by the level shifter, and the like.

  The carriage 101 selectively applies a required drive waveform included in the drive waveform input from the head drive unit 19 to the actuator means of the heads 101a to 101d by controlling on / off of the analog switch array. Then, the heads 101a to 101d are driven. The light source driving unit 20 drives the light sources 101e and 101f to emit light by outputting a light emission signal to the carriage 101 at a predetermined timing after the molding material is ejected from the heads 101a to 101d by the processing as described above. The molding material discharged on the recording table 103 is cured.

  Such a molding material discharge process is executed by the main scanning motor 140 while the carriage 101 moves on the guide rail 102 in the main scanning direction, thereby completing the ejection and exposure of the molding material for one line in the main scanning direction. This process for one line in the main scanning direction is repeated while the recording stage 103 is moved in the sub-scanning direction by the sub-scanning motor 150, so that one layer of molding material is discharged over the entire surface in the main scanning direction and the sub-scanning direction. And the exposure is completed. By repeating the process for one layer and laminating the layers of the cured molding material, the 3D modeling output by the 3D printer 1 according to the present embodiment is completed.

  Next, a problem that the 3D printer 1 according to the present embodiment aims at will be described with reference to FIGS. The 3D printer 1 according to the present embodiment first forms a base layer as a base on the recording base 103, and forms a white background layer that becomes a paper white portion near the surface with white photocurable ink. And the image used as a colored layer is formed in the outermost layer using the colored photocurable ink. In some cases, a varnish layer may be further formed from above for the purpose of gloss / protection. Since the carriage 101 is provided with the plurality of heads 101a to 101d, different materials can be discharged in this way.

  If the ejection of the material from the heads 101a to 101d is executed without error with respect to the design, the three-dimensional object formed on the recording table 103 becomes as the input 3D data. However, as shown in FIG. 4B, there may be an error in the design, for example, when the discharge direction of the material from the heads 101a to 101d is inclined. When such an error is accumulated over a plurality of layers, as shown in FIG. 4B, irregularities different from the 3D data are generated on the surface of the formed three-dimensional object.

  As one mode for solving such a problem, the discharge direction corresponding to each pixel constituting the cut data for one layer is divided into a plurality of times to disperse the error direction and make the landing position uniform as a whole. There is a method called multipath. According to this method, it is possible to solve the above-described problem, but since the discharge is performed in a plurality of times, the time required for the output is increased correspondingly, and the productivity is lowered.

  As a method other than the above-described multi-pass method, the material discharged onto the recording table 103 is leveled by securing the time until the material spreads under gravity and eventually forms a uniform surface before curing, and then cures. There is a method called. With such a process, even if there is ejection unevenness, the valleys are filled and the bumps sink due to the ink spreading, and it is possible to eliminate irregularities such as cracks and bumps from the modeled object.

  FIGS. 5A to 5C are diagrams illustrating an example of leveling. As shown in FIG. 5 (a), the material that has landed on the recording table 103 spreads after being uniformed to some extent as shown in FIG. 5 (b). Spread uniformly as shown.

  As shown in FIGS. 5A to 5C, if sufficient time for leveling can be secured, it is possible to correct the deviation of the landing position of the discharged material without performing multi-pass. However, securing such sufficient time still takes time. In particular, the photocurable ink has a viscosity several times to several tens of times that of the ink for two-dimensional recording, and requires a certain amount of time until it becomes uniform. Therefore, in the 3D printer 1 in which it is necessary to repeatedly form layers, such a time is accumulated and it becomes a very long time.

  In the 3D printer 1 according to this embodiment, the recording platform 103 is vibrated by the functions of the X direction shaker 104, the Y direction shaker 105, and the Z direction shaker 106, thereby dispersing the ink landing positions. The action of FIGS. 5A to 5C is accelerated by the effect of vibration, thereby enabling leveling in a short period. Hereinafter, characteristic functions of the present embodiment will be described.

  FIG. 6A is a diagram illustrating a case where the vibration of the recording table 103 according to the present embodiment is not applied, and FIG. 6B is a diagram illustrating a case where the vibration of the recording table 103 according to the present embodiment is applied. FIG. 6A and 6B, the planes in the X and Y directions, that is, the planes perpendicular to the direction in which the discharge liquid is discharged from the carriage 101 to the recording table 103 are shown. . In other words, the X and Y directions are directions perpendicular to the direction in which the heads 101a to 101d and the recording table 103 face each other. As shown in FIG. 6A, in the case where the vibration of the recording table 103 is not applied, a case where a streak that causes a crack occurs due to the deviation of the landing position as indicated by P in the figure is considered.

  On the other hand, as shown in FIG. 6B, the recording table 103 is vibrated in the X direction and the Y direction described in FIG. 1, that is, the main scanning direction and the sub-scanning direction. As shown on the right side, it is possible to obtain a state in which the landing positions of the respective discharge liquids are dispersed and the deviation of the landing positions is uniformized as a whole.

  Thereby, it is possible to disperse the landing positions of the discharge liquid without applying the multi-pass method as described above, that is, without reducing the productivity. Further, since the recording table 103 vibrates, the leveling operation described in FIGS. 5A to 5C is promoted more than the stationary state, so that a long time is not secured for the leveling. Thus, the leveling effect described in FIGS. 5A to 5C can be obtained.

  The magnitude of dispersion of the landing positions as shown in FIG. 6B depends on the amplitude when the recording table 103 is vibrated. Since the purpose is to disperse the deviation of the landing positions as shown in FIG. 6A, the magnitude of the amplitude when the recording stage 103 is vibrated is set according to the recording resolution at the time of forming each layer. It is preferable. For example, when the recording resolution is low, it is necessary to increase the amplitude and obtain a dispersion amount corresponding to the roughness of the dot pitch. Here, the dot pitch is an interval between droplets discharged to adjacent regions on a plane on which the molding material is discharged.

  Specifically, for example, when the recording resolution pitch is p, it is preferable to set an amplitude of about ± 1 / 4p to 1 / 2p. In addition, the amount of dispersion varies depending on the combination of ejection characteristics of individual nozzles, variation in the feed amount of the printing table, and vibration. However, when the period of vibration is f, a fluctuation component such as 1 / f is intended. May be added.

  FIG. 6B shows an example in which the recording table 103 is vibrated in the X and Y directions shown in FIG. In order to disperse the landing positions of the discharge liquid, it is necessary to vibrate the recording table 103 in the X and Y directions. However, if the vibration is also performed in the X and Y directions during leveling after the discharge liquid has landed. The material spreads more than necessary, and details may be crushed or exuded. Therefore, it is preferable to vibrate the recording table 103 in the Z direction shown in FIG. 1 during leveling after the discharge liquid has landed. The Z direction is a direction parallel to the direction in which the discharge liquid is discharged from the carriage 101 to the recording table 103. In other words, the Z direction is a direction parallel to the direction in which the heads 101a to 101d and the recording table 103 face each other.

  FIGS. 7A to 7C are diagrams showing signal directions from the landing of the discharged liquid to the leveling. As shown in FIG. 7A, when the discharged liquid lands, the recording table 103 is vibrated in the X and Y directions to disperse the landing positions as shown in FIG. 6B. On the other hand, after the discharge liquid has landed on the recording table 103, the recording table 103 is vibrated in the Z direction as shown in FIG. Accordingly, leveling can be promoted without causing the above-described details to be crushed or exuded. Thereafter, in order to settle the surface of the landed material, the vibration of the recording table 103 is stopped as shown in FIG. 7C before exposure by the light sources 101e and 101f.

  Such vibration in the Z direction can be performed for the purpose of roughening the surface of the molding material in addition to promoting leveling. 8 (a) to 8 (d) show such an embodiment. FIG. 8A shows a state in which the material on the recording table 103 is made uniform by leveling. When vibration in the Z direction is applied in this state, the surface of the uncured molding material undulates according to the vibration as shown in FIG.

  When exposure is performed by the light sources 101e and 101f as shown in FIG. 8C in a state where the surface is waved by vibration in the Z direction, the recording surface is waved as shown in FIG. 8D. The material can be cured. In FIG. 8C, only a part of the molding material is exposed while the recording table 103 is vibrated, and only a part of the molding material is undulated as shown in FIG. Descent. By such treatment, it is possible to intentionally roughen the laminated surface of the molding material.

  Such an embodiment can be used, for example, to improve the bonding strength between the stacked layers. The bonding strength between the stacked layers is stronger on a rough surface having irregularities than when the surface of the layer is nearly flat. Therefore, it is possible to improve the bonding strength between the stacked layers by roughening the surface of the layers by the processes shown in FIGS.

  The roughness of the layer surface formed by exciting in the Z direction can be adjusted by the amplitude when vibrating in the Z direction. That is, when it is desired to increase the unevenness, the amplitude is increased, and when it is desired to reduce the unevenness, the amplitude is decreased. This setting can be arbitrarily set by the user, and the CPU 11 controls the pressurizing mechanism piezoelectric element driving unit 23 according to the setting by the user. Thereby, the Z direction vibrator 106 vibrates the recording table 103 in the Z direction with an amplitude according to the setting by the user.

  Next, the operation of the 3D printer 1 according to the present embodiment will be described with reference to FIG. As shown in FIG. 9, when three-dimensional modeling is started based on the input job, the CPU 11 determines whether or not the target portion from which the molding material is discharged is a finely processed portion (S901). For the determination in S901, the controller 100 according to the present embodiment determines whether each part is a microfabrication part when generating the circular cut data based on the input 3D data, and performs microfabrication for each pixel. Flag information indicating whether or not a portion is a part is set. This process may be performed by the ASIC 15 or may be performed by the CPU 11 that performs calculations according to a predetermined program.

  In step S901, the CPU 11 makes a determination for each pixel based on the flag information set as described above. As a result, if it is a finely processed part (S901 / YES), if the above-described vibration process is performed, the finely processed part may be crushed. A discharge process is performed (S902).

  On the other hand, if it is not a microfabricated part (S901 / NO), the CPU 11 controls the pressurizing mechanism piezoelectric element driving unit 23 to start excitation in the X and Y directions to the recording table 103 (S903). In step S904, the molding material is discharged. When the molding material lands on the recording table 103, the CPU 11 controls the pressurizing mechanism piezoelectric element driving unit 23 to stop the excitation in the X and Y directions on the recording table 103 (S905).

  When the processing of S902 or S905 is completed, the CPU 11 controls the pressurizing mechanism piezoelectric element driving unit 23 to start vibration in the Z direction with respect to the recording table 103 (S906), and in FIGS. Leveling processing is performed as described (S907). When the leveling process by vibration is completed, the CPU 11 confirms whether or not the roughening process is necessary (S908).

  The necessity of the roughening process is determined by, for example, setting by the user, whether or not the layer is far from the surface of the modeled object, and the like. Roughening is necessary when roughening is set by the user, or when the layer is far from the surface of the object and the bonding strength between layers should be given priority over the smoothness of the layer surface. It is judged that.

  When it is determined that the roughening process is necessary (S908 / YES), the CPU 11 controls the light source driving unit 20 to expose and cure the discharged molding material (S909). At this time, since the vibration in the Z direction is continued, the molding material is cured with a rough surface as described in FIGS. When the curing is completed, the CPU 11 controls the pressurizing mechanism piezoelectric element driving unit 23 to stop the excitation in the Z direction with respect to the recording table 103 (S910).

  On the other hand, when it is determined that the surface roughening process is not required (S908 / NO), the CPU 11 controls the pressurizing mechanism piezoelectric element driving unit 23 to stop the excitation in the Z direction with respect to the recording table 103 (S911). . As a result, the uncured molding material changes from a wavy state to a uniform state. Thereafter, the CPU 11 controls the light source driving unit 20 to expose and cure the discharged molding material (S912). At this time, since the excitation in the Z direction is stopped, the surface of the molding material is cured in a smooth state.

  The CPU 11 repeats such processing to repeatedly form a layer of the molding material (S913 / NO). When the formation of the final layer is completed (S913 / YES), the processing ends. By such a process, the three-dimensional modeling process by the 3D printer 1 according to the present embodiment is completed.

  As described above, in the 3D printer 1 according to the present embodiment, when the recording table 103 is vibrated, the landing positions of the discharged droplets of the molding material are dispersed, and the landing positions are biased. In addition to being eliminated, leveling is promoted and a uniform surface can be obtained in a short time. Moreover, it becomes possible to obtain the layer surface which has an unevenness | corrugation as a whole by performing exposure in the vibrated state.

  In the above-described embodiment, the 3D printer 1 that performs three-dimensional solid modeling has been described as an example. However, the present invention can be similarly applied to any droplet discharge recording apparatus that performs at least planar recording by an inkjet method. That is, the same effect can be obtained even when applied to an inkjet printer that forms a flat image or an image having relief-like irregularities.

  In the above embodiment, the case where both the X and Y direction excitations and the Z direction excitation are performed has been described as an example. However, for example, the X and Y direction excitations are not performed and the Z direction excitations are not performed. Only shaking may be performed. This makes it possible to obtain at least an effect of promoting leveling. On the other hand, it is also possible to perform only the vibration in the X and Y directions without performing the vibration in the Z direction. Thereby, it is possible to obtain a dispersion effect of landing positions and an effect of promoting leveling.
