1. 1. Embodiment 1

1.1) Configuration of modeling equipment

FIG. 1 is a schematic side view showing a modeling apparatus according to an embodiment of the present technology. FIG. 2 is a front view of the modeling apparatus 100 shown in FIG. The modeling device 100 mainly includes a stage 10, a drum 30 as a regulator, a material supply mechanism having a nozzle 20, an irradiation unit 40, a stage moving mechanism 60, an irradiation unit moving mechanism 45, a control unit 50, and a detection unit 70. ..

For convenience of explanation, in the three-dimensional space in which the modeling apparatus 100 is arranged, the vertical axis along the height direction is defined as the z-axis, and the two axes along the horizontal plane perpendicular to the z-axis are defined as x and y-axis.

The stage 10 has a modeling surface 12 which is a surface on the side where the modeled object is formed. The stage 10 is arranged above the drum 30, and the modeling surface 12 is arranged toward the side where the drum 30 is located. The stage 10 is arranged so that the modeling surface 12 is tilted at a specific tilt angle in the rotation direction about the y-axis with respect to the horizontal plane xy. Its tilt angle with respect to the xy plane is arbitrarily set

For convenience of explanation, the coordinate system obtained by rotating the (x, y, z) coordinate system around the y-axis by the inclination angle of the stage 10 is defined as the (x', y', z') coordinate system.

The drum 30 is arranged so that the longitudinal axis of the cylinder is along the y-axis. The drum 30 is made of a material that transmits energy rays emitted from the irradiation unit 40. When a photocurable resin is used as a material constituting a modeled object, light is used as an energy ray. Hereinafter, the material constituting the modeled object will be referred to as a resin material. Typically, the resin material is an ultraviolet curable resin and the energy rays are ultraviolet rays. As the material of the drum 30, a transparent material that transmits the ultraviolet rays, such as glass or acrylic, is used.

The material supply mechanism is configured so that the resin material can be supplied between the drum 30 and the stage 10. Specifically, the nozzle 20 in the material supply mechanism is arranged between the drum 30 and the stage 10, and the resin material R (FIG. 3) is formed between the cylindrical surface of the drum 30 and the modeling surface 12 of the stage 10. See) is configured to supply. The nozzle 20 is composed of a plurality of nozzles provided along the y direction, or has a discharge slit having a long shape along the y direction.

Although not shown, the material supply mechanism includes a tank for storing the resin material, a pipe connected to the nozzle 20, a valve provided in the pipe, a pump for pumping the resin material, and the like.

FIG. 3 is an enlarged view of the stage 10 and the drum 30. The surface 32 of the drum 30 has a proximity region K close to the stage 10. The drum 30 is arranged with respect to the stage 10 so as to form a holding region H for holding the resin material R between the proximity region K and the modeling surface 12 of the stage 10. The resin material R is mainly held by surface tension.

Since the drum 30 is arranged below the modeling surface 12 of the stage 10 and the stage 10 is inclined, the uncured resin material R flows diagonally downward along the x'direction of the modeling surface 12 and is removed. It becomes easy to be done.

The holding region H has the narrowest portion (first region) Hc at the position of the region closest to the stage 10 (proximal region) in the proximity region K. The holding region H is a spatial region between the drum 30 and the stage 10 in a range of about several mm to several cm along the circumferential direction of the surface 32 of the drum 30 from the narrowest portion Hc. The range of the holding region H in the circumferential direction of the drum 30 is a value that changes depending on the resin material R, the material of the drum 30, and / or the size of the drum 30, and is several mm to several as described above. Not limited to the cm range.

The distance between the molding surface 12 and the surface 32 of the drum 30 in the narrowest portion Hc is substantially the same as the thickness of one hardened layer of the resin material R. The distance is, for example, 50 μm to 500 μm, but can be arbitrarily set depending on the size and definition of the modeled object at the time of completion.

As shown in FIG. 3, the modeling apparatus 100 further includes a motor (not shown) that rotates the drum 30 around a cylindrical central axis P along the y direction. For example, the motor rotates the drum 30 when the proximity region K with respect to the stage 10 is changed or maintained by rotating the drum 30 by a predetermined angle each time one or a plurality of layers are exposed.

The irradiation unit 40 is arranged inside the cylinder of the drum 30. The irradiation unit 40 selectively irradiates the region of the resin material R held in the holding region H with light via the drum 30. The irradiation unit 40 includes a laser light source (not shown), a polygon mirror, and a lens system, and these components are housed in, for example, one housing. A galvano mirror may be used instead of the polygon mirror.

As shown in FIG. 1, the stage moving mechanism 60 has a first moving mechanism 61 and a second moving mechanism 62. The first moving mechanism 61 is configured to move the stage 10 in the x'direction along the modeling surface 12 of the stage 10 arranged at a predetermined inclination angle. The second moving mechanism 62 is configured to move the stage 10 in the laminating direction of the resin material R, that is, in the direction in which the stage 10 is separated from the drum 30 (z'direction).

The first moving mechanism 61 and the second moving mechanism 62 are composed of various known driving mechanisms such as a ball screw drive, a rack and pinion drive, and a belt drive.

The control unit 50 is configured to control each operation of the stage moving mechanism 60, the irradiation unit moving mechanism 45, the material supply mechanism, and the motor of the drum 30. The control unit 50 is typically composed of a computer equipped with a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The control unit 50 may include a PLD (Programmable Logic Device) such as an FPGA (Field Programmable Gate Array).

The irradiation unit moving mechanism 45 is connected to the irradiation unit 40 and is configured to shift the irradiation unit 40 in at least the x'direction. As the drive method, the above-mentioned known drive mechanism is used. For example, the control unit 50 has a function of variably controlling the irradiation position of light in the x'direction by the irradiation unit 40 by controlling the drive of the irradiation unit moving mechanism 45.

By using at least a part of the functions of the control unit 50 and the irradiation unit moving mechanism 45, the position of irradiating the resin material R with light in the relative moving direction of the stage 10 and the drum 30 (x'direction by the first moving mechanism 61) is determined. A "control mechanism" to control is configured.

The detection unit 70 is installed outside the cylinder of the drum 30. The detection unit 70 has a function of detecting the adhesion of the cured resin material R to the surface 32 of the drum 30. If the cured resin material R adheres to the surface 32 of the drum 30 which is a regulated body, there are various problems and leads to a molding error. For example, in the case of modeling without changing the proximity region K, even if the irradiation unit 40 tries to expose the resin material R, the adhesion of the cured resin material R blocks the exposure. Therefore, there is a possibility that the portion to be formed in the z'direction of the portion to which the cured resin material R is attached may not be formed after the attachment.

When the proximity region K is changed, the portion where the adhesion of the cured resin material R blocks the exposure shifts in the x'direction from the portion where the cured resin material R adheres. Then, similarly, a modeling error occurs in which the portion to be modeled in the z'direction is not modeled.

Since the detection unit 70 detects the adhesion of the cured resin material R on the surface 32 of the drum 30, the modeling apparatus 100 according to the present embodiment can detect a modeling error at an early stage.

With reference to FIGS. 4 and 5, detailed configurations of the detection unit 70 are shown. FIG. 4 is a view of the surface 32 viewed from the outside of the drum 30, and FIG. 5 is a side view of FIG. As shown in the figure, the detection unit 70 according to the present embodiment is a physical detection unit 71 that physically detects a foreign substance. The physical detection unit 71 has one or more wires 72 and a displacement detection unit 73.

In FIGS. 4 and 5, when the adhesion of the cured resin material R is detected, the drum 30 rotates in the “resin recovery direction (counterclockwise rotation)” in the drawing. In FIGS. 1, 3 and 5, the rotation is in the counterclockwise direction.

The wire 72 is a member that projects toward the surface 32 of the drum 30, and is made of, for example, a flexible metal material. The tip of the wire 72 on the drum 30 side may be bent so as not to be pierced when it comes into contact with the foreign matter ST on the surface 32 (see FIG. 5).

The end of the wire 72 in the direction away from the drum 30 is connected to or is connected to the displacement detection unit 73. The wires 72 are installed in a comb-teeth shape on the displacement detection unit 73 at a predetermined pitch (interval). The shorter the predetermined pitch, the finer the size of the foreign matter ST that can be detected.

The tip of the wire 72 on the drum 30 side is configured so as not to reach the surface 32. As a result, the presence of the foreign matter ST can be detected without damaging the surface 32. The height of the detectable foreign matter ST is determined according to the distance between the surface 32 and the tip portion.

The displacement detection unit 73 is configured to be able to detect the displacement of the wire 72 in contact with the foreign matter ST when the foreign matter ST comes into contact with any one or more of the wires 72. The displacement of the wire 72 may be a deformation of the wire 72 or a change in the spatial position of the wire 72. For example, when the contact point between the wire 72 and the displacement detection unit 73 is formed of a member such as a hinge, when the foreign matter ST comes into contact with the wire 72, the wire 72 is pushed up and rotates around the hinge portion. The displacement detection unit 73 may detect such a change in the spatial position of the wire 72.

When the displacement detection unit 73 detects the displacement of the wire 72, the displacement detection unit 73 sends a detection signal to the control unit 50. The detection signal may include a displacement amount. As described above, the physical detection unit 71 according to the detection unit 70 of the present embodiment detects that the cured resin material R is attached to the surface 32 of the drum 30.

1.2) Operation of modeling equipment

More specifically, the location where the detection unit 70 is installed may be just outside the holding region H where the modeling is performed. In this case, the possibility that the adhesion of the cured resin material R to the surface 32 can be detected immediately after the adhesion is increased. Since it is preferable that the cured resin material R does not adhere to the surface 32 at all, it may be detected even inside the holding region H depending on the mode of the detection unit 70.

In the present embodiment, the installation location of the detection unit 70 is immediately outside the holding area H where modeling is performed. Further, there are two outside of the holding region H, a resin discharge side and a resin recovery side, but in the present embodiment, the resin discharge side is used (see FIG. 1). In the following, assuming the installation location of the detection unit 70 described here, the operation of the modeling apparatus will be described focusing on the detection of adhesion of the cured resin material R to the surface 32.

With reference to FIG. 6, the flow of the adhesion detection operation of the cured resin material R on the surface 32 of the modeling apparatus 100 is shown. As shown in the figure, the irradiation unit 40 exposes the uncured resin material R flowing in the narrowest portion Hc between the molding surface 12 and the surface 32 of the drum 30 (S101). At this time, the first moving mechanism 61 moves the stage 10 in the x'direction along the modeling surface 12 of the stage 10, but in the present embodiment, the first moving mechanism 61 moves the resin material R in the direction in which the resin material R flows. Move the stage 10 toward it. That is, the stage 10 moves in the upper left direction in FIG.

With the movement of the stage 10, the drum 30 rotates about the cylindrical central axis P in the forward direction with respect to the movement of the stage 10. In this embodiment, this rotation direction is referred to as "reverse rotation", and the opposite is referred to as "forward rotation".

The rotation of the drum 30 may be performed by a motor (not shown) controlled by the control unit 50, but in the present embodiment, the drum 30 is rotated by a frictional force as the stage 10 moves (S101).

When the drum 30 rotates with the modeling, the proximity region K with respect to the stage 10 on the surface 32 on which the modeling was performed moves to the area that can be detected by the detection unit 70, so that the detection unit 70 detects foreign matter (S102). ). When the detection unit 70 does not detect a foreign object (S103, No), the control unit 50 controls the drum 30 to rotate the drum 30 in the forward direction (S106).

The amount of return by forward rotation is arbitrary. In the present embodiment, the return amount is set to be larger than the rotation amount that is accompanied by the movement of the stage 10, and the proximity region K is replaced. The forward rotation of S106 is configured so that the drum 30 is rotated when the first moving mechanism 61 moves the stage 10 in the direction in which the resin material R flows down, and the rotation control of the drum 30 is performed by the control unit 50. May not be performed.

In addition, even when the first moving mechanism 61 moves the stage 10 in the direction in which the resin material R flows down, the irradiation unit 40 may perform exposure to perform modeling, but in the present embodiment, the molding may be performed. It is assumed that the first moving mechanism 61 performs modeling only when the stage 10 is moved in the direction in which the resin material R flows.

When the detection unit 70 detects a foreign matter (S103, Yes), the control unit 50 notifies the operator that the foreign matter has been detected (S104). That is, the control unit 50 functions as a "notification unit". As a result, the operator can know the modeling error at an early stage, and by stopping the operation of the modeling device 100, the loss of opportunity cost, the loss of the resin material R, and the like can be prevented at an early stage. The notification method is not limited, but may be configured to send a warning e-mail, for example.

Next, the control unit 50 changes the modeling data so that the article corresponding to the location where the foreign matter is detected is not exposed by the irradiation unit 40 (S105). As shown in FIGS. 4 and 5, the detection unit 70 of the present embodiment has wires 72 installed in a comb-teeth shape, and the displacement detection unit 73 contains foreign matter ST related to adhesion of the cured resin material R. The position existing on the surface 32 of the drum 30 can be grasped. The control unit 50 modifies the modeling data so that the article corresponding to the position of the foreign matter ST grasped by the displacement detection unit 73 is not exposed in the modeling after the foreign matter ST is detected.

Next, the control unit 50 rotates the drum in the forward direction to continue modeling. The operation flow shown in FIG. 6 ends at that point when the control unit 50 detects the end of the modeling data or the interruption by the operator.

2. Embodiment 2

2.1) Configuration of modeling equipment

FIG. 7 is a schematic side view showing a modeling apparatus according to an embodiment of the present technology. The detection unit 70 included in the illustrated modeling device 200 includes a photodetector 75 that detects foreign matter ST related to adhesion of the cured resin material R by optical means.

The detection unit 70 includes a photodetector 75 including an image pickup unit 76 and an air injection unit 77, and an image processing unit 78 that performs image processing. In the present embodiment, the control unit 50 provides the function of the image processing unit 78, but the configuration is not limited to this, and the image processing unit 78 may be configured by a processor separate from the control unit 50.

The imaging unit 76 is an area sensor configured to image the surface 32 of the drum 30, and is configured to include a photoelectric conversion element and the like. The air injection unit 77 has a function of injecting air toward the uncured resin material R adhering to the surface 32. The uncured resin material R is usually viscous. The strength of the air injected by the air injection unit 77 and the amount of air are not limited, but may be configured to such that the uncured resin material R sticking to the surface 32 can be blown off.

The place where the photodetector 75 is installed is not limited, but is set on the resin phase amount discharge side with respect to the yz plane passing through the cylindrical central axis P along the y direction as shown in FIG. In the present embodiment, modeling is performed while moving the stage 10 in the x'direction along the modeling surface 12 of the stage 10. Similar to the first embodiment, the modeling may be performed only when the first moving mechanism 61 moves the stage 10 in the direction in which the resin material R flows, but unlike the first embodiment, the resin material R may be formed. The modeling may be performed even when the stage 10 moves in the direction in which the plastic flows down.

In any case, the rotation amount of the forward rotation of the drum 30 is set to be larger than the rotation amount of the reverse rotation. The definition of forward rotation and reverse rotation is the same as that of the first embodiment. Then, the proximity region K alternates with the region on the resin material discharge side of the drum 30, and the surface 32 on the resin material recovery side enters the region that can be imaged by the imaging unit 76 of the photodetector 75.

The imaging unit 76 constantly images the surface 32 of the drum 30. The air injection unit 77 injects air at the timing when the drum 30 rotates in the forward direction.

The image processing unit 78 detects the foreign matter ST related to the cured resin material R based on the image captured by the image pickup unit 76. In addition to the image captured by the imaging unit 76, the x'y'plane data obtained based on the modeling data is also input to the image processing unit 78. The image processing unit 78 performs edge enhancement processing on the image captured by the imaging unit 76, compares it with the x'y'plane data having a predetermined z'coordinate, and performs pattern matching. The image processing unit 78 recognizes that the foreign matter ST may be present where the matching pattern appears.

When it is recognized that the foreign matter ST does not exist, the image processing unit 78 is configured to change the z'coordinates to perform pattern matching between another x'y'plane data and the image captured by the imaging unit 76. May be done.

The image processing unit 78 compares the images of the surface 32 of the drum 30 before and after the air injection by the air injection unit 77, and there is no change after the air injection, and the foreign matter is detected in the edge. Information processing may be performed to increase the likelihood that ST is present. In this case, the image processing unit 78 further performs pattern matching between the x'y'plane data having a predetermined z'coordinate and the image including the edge image of the portion where the foreign matter ST is present and the likelihood is increased, and the foreign matter ST is performed. May be detected that is likely to be present.

When it is recognized that the foreign matter ST is present or is likely to be present, the image processing unit 78 determines that the cured resin material R is attached to the surface 32 and detects it. To do.

3. 3. Modification example

The above-described first and second embodiments can be combined. When the physical detection unit 71 detects the displacement of the wire 72 immediately after modeling, the control unit 50 determines that the foreign matter ST may be present at the displacement detection location. When it is determined that the foreign matter ST may be present, the control unit 50 increases the amount of forward rotation of the drum 30 and moves the region where the foreign matter ST may be present to the detection region by the photodetector 75. Let me. When the photodetector 75 also recognizes that the foreign matter ST may be present, the control unit 50 determines that the foreign matter ST is attached. According to this modification, there is an effect that the possibility of detecting the adhesion of the cured resin material R is increased.
