Description

[Technical Field]

[0001] The present invention relates to a work stage and a work system, and more particularly to a work stage and a work system equipped with a work stage that are used for modeling operations using a three-dimensional modeling device and for processing operations using a cutting device. [Background technology]

[0002] Conventionally, 3D printer technology has been known that can create three-dimensional objects by layering three-dimensional modeling materials in three dimensions using 3D-CAD (Computer Aided Design) data created on a computer as a blueprint. For example, 3D printer technology using fused deposition modeling (FDM) is widely known, in which thermoplastic resin, which serves as the material for three-dimensional modeling, is melted and extruded from the nozzle of an extruder, and then layered on a work stage to create a model.

[0003] Patent Document 1 discloses a work stage that layers a modeling material extruded from the nozzle of an extruder. The work stage for a three-dimensional modeling device described in Patent Document 1 has a platform sheet made of a non-polar resin material, and holds a three-dimensional model by fusing the modeling material to the platform sheet. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2020-104373 Summary of the Invention [Problem to be solved by the invention]

[0005] Generally, a three-dimensional object formed on a work stage by a three-dimensional printing device is polished or drilled to produce a more precise product. When cutting is performed directly on the work stage for the three-dimensional printing device, it is necessary to prevent the three-dimensional object from shifting out of position. However, the platform sheet described in Patent Document 1 has a low holding force for the three-dimensional object, which may cause the object to shift out of position. Furthermore, in order to improve the holding force of the three-dimensional object, it is conceivable to press and hold the object using, for example, a plate-shaped clamping member, but since three-dimensional objects often have complex shapes with many curved surfaces, there is a risk that plate-shaped clamping members may not be able to adequately hold three-dimensional objects of various shapes.

[0006] The present invention has been made in consideration of the above-mentioned problems, and an object of the present invention is to provide a work stage and work system that can share a work space for both modeling work and processing work, and can stably hold three-dimensional objects of various shapes. [Means for solving the problem]

[0007] The above-mentioned problem is solved by a work stage of the present invention, which is a work stage used for modeling operations using a three-dimensional modeling device and processing operations using a cutting device, and includes: a mounting table for modeling and processing a three-dimensional object; and a plurality of holding members movably attached to the mounting table and holding the three-dimensional object, wherein the mounting table has a mounting section for stacking modeling material and a long guide section provided on an upper surface of the mounting section for guiding the holding members, and each of the plurality of holding members has a base section that moves along the mounting section, an attachment section that is provided on the base section and movably attached to the guide section, a connection section that is connected to the base section, and a support section that is connected to the connection section and supports the three-dimensional object modeled on the mounting table, and the support section is attached to the connection section via a ball joint or a rotary joint that rotates around a plurality of axes.

[0008] With the above configuration, when shifting from modeling work to processing work, the work stage can be changed according to the purpose of the work by moving the holding member to hold the three-dimensional object. Therefore, the three-dimensional object can be held according to the purpose of the work without moving the work location, which improves work efficiency. Furthermore, since the position of the support part can be adjusted by a ball joint or a rotary joint, even a three-dimensional object having a complex curved surface can be stably held. Therefore, the work space can be used for both modeling and processing, and three-dimensional objects of various shapes can be stably held.

[0009] In this case, a plurality of guide portions may be formed on the upper surface of the placement portion, a plurality of holding members may be attached to the plurality of guide portions, respectively, and the plurality of holding members may be arranged to surround the three-dimensional object by moving the attachment portions along the guide portions. With the above configuration, the plurality of holding members are arranged to surround the three-dimensional object, so that the three-dimensional object can be held more stably even if it has a complex curved surface.

[0010] In this case, the guide portion may be a plurality of grooves formed on the upper surface of the mounting portion, and the mounting table may fix the three-dimensional object by inserting a portion of the three-dimensional object into the grooves. With the above configuration, the grooves formed to allow the modeling material to enter the grooves allow the modeling material to be fixed to the mounting table. This allows the three-dimensional model to be stabilized even during modeling work. Furthermore, since the holding member is moved using the fixing grooves, the component can be used for both modeling work and processing work. This reduces the manufacturing cost of the work stage.

[0011] In this case, the connection portion has a screw portion extending along the length of the guide portion, and a screw hole that screws into the screw portion is formed in the upper part of the base portion, and the connection portion is capable of adjusting the position of the support portion in the length direction of the guide portion by rotating the screw portion relative to the screw hole. With the above configuration, by rotating the screw portion and finely adjusting the position of the support portion, it is possible to easily hold a three-dimensional object, even if it has a complex curved surface.

[0012] In this case, the guide portion is a groove formed on the upper surface of the placement portion, the mounting portion has a fixing screw portion extending in the vertical direction, a fixing screw hole that screws into the fixing screw portion is formed in the lower part of the base portion, the lower end of the mounting portion abuts against the bottom surface of the groove as the fixing screw portion rotates relative to the fixing screw hole, and the base portion is fixed to the placement portion as the lower end of the mounting portion abuts against the bottom surface of the groove. With the above-described configuration, the position of the holding member can be fixed with a simple configuration by rotating the fixing screw portion.

[0013] Furthermore, the above problem is solved by a work system of the present invention, which includes the work stage, the three-dimensional modeling device that stacks the modeling material on the work stage, and the cutting device that cuts the three-dimensional object modeled by the three-dimensional modeling device on the work stage, wherein the multiple holding members are switchable between a normal position where they are positioned at the end of the guide section and a holding position where they hold the three-dimensional object, and when the three-dimensional object is cut on the work stage, they are switched from the normal position to the holding position. With the above configuration, when shifting from modeling work to processing work, the work stage can be changed according to the purpose of the work by moving the holding member to hold the three-dimensional object. Therefore, the three-dimensional object can be held according to the purpose of the work without moving the work location, which improves work efficiency.

[0014] In this case, the system may include a manipulator to which either the three-dimensional modeling device or the cutting device can be attached and which moves the three-dimensional modeling device or the cutting device, an attachment provided on the manipulator and which allows the three-dimensional modeling device and the cutting device to be interchangeable, a first storage rack for storing the three-dimensional modeling device, and a second storage rack for storing the cutting device, and the work stage may be positioned adjacent to the first storage rack, the second storage rack, and the manipulator. With the above configuration, when switching from modeling work to machining work, the attachment can be used to switch between the 3D modeling device and the cutting device. Therefore, by using the same device as both the manipulator and the work stage, it is possible to save space in the work area. [Effects of the Invention]

[0015] According to the working stage and working system of the present invention, the working space can be used for both modeling work and processing work, and three-dimensional objects of various shapes can be stably held. [Brief explanation of the drawings]

[0017] 1 to 8, a working system 1 according to one embodiment of the present invention (hereinafter referred to as the present embodiment) will be described. The present embodiment relates to a "working stage and working system" that includes a working stage used for modeling work using a three-dimensional modeling device and for processing work using a cutting device, that can share a working space for modeling work and processing work, and that can stably hold three-dimensional objects of various shapes.

[0018] <Working System> The working system 1 is a system for forming a three-dimensional object M and processing the three-dimensional object M. As shown in Fig. 1 , the working system 1 includes a working stage 2 used for the forming operation and the processing operation, a three-dimensional forming device 3 that stacks a forming material Ma on the working stage 2, a cutting device 4 that cuts the three-dimensional object M on the working stage 2, a manipulator 5 that moves the three-dimensional forming device 3 or the cutting device 4, an attachment 6 that can interchangeably attach the three-dimensional forming device 3 and the cutting device 4, a first storage rack 7 for storing the three-dimensional forming device 3, a second storage rack 8 for storing the cutting device 4, and a control device 9 that controls the three-dimensional forming device 3, the cutting device 4, and the manipulator 5.

[0019] The work stage 2 is used for modeling operations by the three-dimensional modeling device 3 and for processing operations by the cutting device 4. As shown in FIG. 1 , the work stage 2 has a long rectangular shape and is disposed adjacent to the first storage rack 7, the second storage rack 8, and the manipulator 5. Specifically, the work stage 2 is disposed in a position facing the first storage rack 7 and the second storage rack 8 in the longitudinal direction, and in a position facing the manipulator 5 in the lateral direction. In other words, the work stage 2 is disposed in a position surrounded by the first storage rack 7, the second storage rack 8, and the manipulator 5. By arranging the first storage rack 7, the second storage rack 8, and the manipulator 5 near the work stage 2, it is possible to smoothly switch between the modeling operation and the processing operation. The arrangement of the work stage 2, the first storage rack 7, the second storage rack 8, and the manipulator 5 is not limited, and for example, the first storage rack 7 and the second storage rack 8 may be arranged side by side.

[0020] A dustproof plate 2a is attached to the side of the work stage 2 other than the side facing the manipulator 5. The dustproof plate 2a is a cover that prevents chips generated when the three-dimensional object M is cut from scattering during processing. The dustproof plate 2a also prevents the modeling material Ma from scattering outside the work stage 2 during modeling work.

[0021] The three-dimensional modeling device 3 is an extruder that stacks modeling material Ma on the work stage 2 to form a three-dimensional object M. Specifically, the three-dimensional modeling device 3 is a 3D printer that creates a three-dimensional object by stacking two-dimensional layers sliced ​​based on 3D-CAD data. The modeling material Ma may be, for example, pellets of a thermoplastic resin. The pellets are heated and melted inside the three-dimensional modeling device 3 and extruded from the three-dimensional modeling device 3. The heated and melted pellets are then deposited on the working stage 2, cooled, and hardened.

[0022] The three-dimensional modeling device 3 has a cylinder unit that melts the modeling material Ma, a screw unit disposed within the cylinder unit, and a nozzle unit that discharges the molten modeling material Ma. The modeling material Ma melted in the cylinder unit is sent from the cylinder unit to the nozzle unit by the screw unit, and is then discharged from the nozzle unit. The modeling material Ma discharged from the nozzle unit is then repeatedly layered on the work stage 2, thereby forming a three-dimensional model M. The modeling material Ma is not limited to pellets that have been heated and melted in the cylinder. For example, the modeling material Ma may be filaments that have been melted by frictional heat in the screw.

[0023] The cutting device 4 cuts the three-dimensional object M formed by the three-dimensional printing device 3 on the work stage 2. Examples of cutting work performed by the cutting device 4 include polishing and drilling. The cutting device 4 has a processing unit that processes the three-dimensional object M.

[0024] The manipulator 5 is a robot arm for moving the 3D modeling device 3 or the cutting device 4. The 3D modeling device 3 and the cutting device 4 are attached to the tip of the manipulator 5 via an attachment 6. Either the 3D modeling device 3 or the cutting device 4 can be attached to the manipulator 5 via the attachment 6. The manipulator 5 is provided between the first storage rack 7 and the second storage rack 8 in the longitudinal direction of the work stage 2. This improves the work efficiency when switching between the 3D printing device 3 and the cutting device 4. Furthermore, by using the manipulator 5, the work efficiency can be improved even when printing or processing a large 3D object M.

[0025] When the three-dimensional modeling device 3 is attached to the tip of the manipulator 5 via the attachment 6, the manipulator 5 moves the three-dimensional modeling device 3 onto the working stage 2 to perform modeling work. Furthermore, when the cutting device 4 is attached to the tip of the manipulator 5 via the attachment 6, the manipulator 5 moves the cutting device 4 onto the work stage 2 to perform processing work.

[0026] The attachment 6 is a connecting member provided at the tip of the arm of the manipulator 5. The attachment 6 makes it possible to easily replace the 3D printing device 3 and the cutting device 4. The replacement work may be performed automatically by the control device 9 or manually by an operator.

[0027] The first storage rack 7 is a rack for storing the three-dimensional modeling device 3. When modeling work is not being performed, the three-dimensional modeling device 3 is detached from the tip of the manipulator 5 and stored in the first storage rack 7.

[0028] The second storage rack 8 is a rack for storing the cutting device 4. When no processing work is being performed, the cutting device 4 is detached from the tip of the manipulator 5 and stored in the second storage rack 8.

[0029] The control device 9 is a computer that controls the 3D printing device 3, the cutting device 4, and the manipulator 5. The control device 9 acquires printing information for printing the 3D object M and processing information for processing the 3D object M, and controls the 3D printing device 3, the cutting device 4, and the manipulator 5. Specifically, the control device 9 controls the nozzle unit and manipulator 5 of the three-dimensional modeling device 3 based on the acquired modeling information (coordinate information, speed information, discharge amount information, etc.). The control device 9 also controls the processing unit and manipulator 5 of the cutting device 4 based on the acquired processing information (coordinate information, speed information, cutting amount information, etc.).

[0030] <Working stage> As shown in FIG. 2, the work stage 2 includes a mounting table 10 for forming and processing the three-dimensional object M, and a plurality of holding members 20 that are movably attached to the mounting table 10 and hold the three-dimensional object M. In the modeling operation, a large space is required because the modeling material Ma is discharged onto the work stage 2 and layered in three dimensions. In the processing operation, the processing part of the cutting device 4 comes into direct contact with the three-dimensional model M, so a stronger holding force is required. Therefore, during the modeling operation, the multiple holding members 20 are placed in normal positions (FIGS. 2 and 3) that do not interfere with the modeling operation, and during the processing operation, they are switched from the normal positions to holding positions (FIGS. 4 to 6) that hold the three-dimensional model M.

[0031] <Placement table> The mounting table 10 is a stage for forming and processing the three-dimensional object M. As shown in FIGS. 2 and 3 , the mounting table 10 has a mounting section 11 on which the forming material Ma is stacked, and a long guide section 12 provided on the upper surface of the mounting section 11 and guiding the holding member 20. The guide section 12 extends long along the short side direction of the working stage 2. As shown in Figures 7 and 8, the mounting table 10 is configured by arranging multiple rail members extending in the short side direction in parallel in the longitudinal direction. The rail members are, for example, aluminum members having a square cross section. The upper surface of the rail members constitutes the mounting portion 11, and the rail grooves formed in the upper surface of the rail members constitute the guide portion 12.

[0032] 3, the mounting portion 11 is a flat surface on which the modeling material Ma is layered. When the modeling material Ma is layered on the mounting portion 11, the three-dimensional model M is adhered to the mounting portion 11 to such an extent that it can be peeled off. A plurality of guide portions 12 are formed on the upper surface of the mounting portion 11.

[0033] 3, the guide portions 12 are a plurality of grooves formed on the upper surface of the mounting portion 11. The guide portions 12 are formed so as to extend linearly in the short side direction of the working stage 2. The guide portion 12 is formed to extend in the short-side direction, but may also be formed to extend in the long-side direction. The guide portion 12 may also be formed in a curved shape, or in a lattice shape that intersects the short-side direction and the long-side direction.

[0034] 6, a plurality of holding members 20 are attached to each of the plurality of guide portions 12. Specifically, a large number of guide portions 12 are formed so as to be lined up in the longitudinal direction, and two holding members 20 are attached to one guide portion 12. More specifically, four pairs of holding members 20 are provided to hold the three-dimensional object M in the lateral direction, and a total of eight holding members 20 are attached to the mounting table 10. Note that the positions, number, and shapes of the guide portions 12 are not limited to these. In this way, the three-dimensional object M can be held from various directions by the multiple holding members 20. Furthermore, by configuring multiple holding members 20 to be attached to one guide part 12, the three-dimensional object M can be clamped from both sides.

[0035] 3, the shaping material Ma discharged from the nozzle of the three-dimensional modeling device 3 during modeling operation enters the guide portion 12. That is, the groove of the guide portion 12 is formed to a size that allows the shaping material Ma to enter and that can guide the holding member 20. The mounting table 10 fixes the three-dimensional object M by having a portion of the three-dimensional object M enter the groove of the guide portion 12. In this way, the three-dimensional object M can be stabilized even during the modeling operation. In addition, since the holding member 20 is moved using the grooves for fixing, the component can be used both during the modeling operation and the processing operation. Therefore, the manufacturing cost of the work stage 2 can be reduced.

[0036] 2, the multiple holding members 20 are arranged at the ends in the length direction of the guide section 12 (the short side direction of the working stage 2). This makes it possible to widen the working space on the working stage 2. The plurality of holding members 20 may be detachable from the guide unit 12. By removing the holding members 20 from the working stage 2, the working space can be made larger.

[0037] 4, the multiple holding members 20 are positioned to hold the three-dimensional object M. This allows the three-dimensional object M to be held more firmly even when the processing part of the cutting device 4 comes into contact with the three-dimensional object M.

[0038] <Retaining member> 4 to 6, the holding member 20 is a member for holding the three-dimensional object M. As shown in FIGS. 7 and 8, the holding member 20 has a base portion 21 that moves along the placement portion 11, an attachment portion 22 that is movably attached to the guide portion 12, a connection portion 23 that is connected to the base portion 21, and a support portion 24 that supports the three-dimensional object M. 7 is a diagram showing one holding member 20 attached to one rail member. The "front-rear direction" in FIG. 7 is the length direction of the guide part 12, with the support part 24 side being the front side (the direction toward the three-dimensional object M is the front direction).

[0039] A plurality of holding members 20 are provided on the mounting table 10, and are arranged to surround the three-dimensional object M as the mounting portions 22 of each move along the guide portions 12. The holding members 20 are attached to the mounting portion 11 so as to be switchable between a normal position (FIG. 2) and a holding position (FIG. 4). When the three-dimensional object M is cut on the work stage 2, the holding members 20 are switched from the normal position to the holding position.

[0040] 7, the base portion 21 is, for example, an aluminum member having a triangular shape in a side view. The base portion 21 is attached to the upper surface of the mounting portion 11 by an attachment portion 22, and moves along the mounting portion 11. Specifically, the base portion 21 moves in the length direction (front-rear direction) of the guide portion 12. The base portion 21 has an attachment base portion 21a on which the attachment portion 22 is provided, a connection base portion 21b on which the connection portion 23 is provided, and left and right reinforcing wall portions 21c that connect the attachment base portion 21a and the connection base portion 21b.

[0041] The mounting base portion 21a is a plate-like member that is long in the front-rear direction. The connection base portion 21b is a plate-like member that is long in the up-down direction. The mounting base portion 21a and the connection base portion 21b are arranged perpendicular to each other and have an L-shape. The reinforcing wall portion 21c is a rib having a triangular shape in a side view, and is provided on both sides of the mounting base portion 21a and the connection base portion 21b. The reinforcing wall portion 21c improves the strength of the base portion 21. Furthermore, by covering the mounting portion 22 with the reinforcing wall portion 21c, chips and the like generated during cutting work are prevented from entering the mounting portion 22.

[0042] A fixing screw hole 21d that screws into a fixing screw portion 22a (described later) is formed in a lower portion of the base portion 21. The fixing screw hole 21d is a through-hole that is formed in the mounting base portion 21a and penetrates in the up-down direction. A plurality of screw holes 21e that screw into screw portions 23a (described later) are formed in the upper portion of the base portion 21. The plurality of screw holes 21e are through-holes that penetrate in the front-rear direction and are formed in the upper end portion of the connection base portion 21b. Because a plurality of screw holes 21e are provided in the up-down direction, the height position of the support portion 24 can be adjusted.

[0043] 7, the mounting portion 22 extends downward from the mounting base portion 21a of the base portion 21, and is attached so as to be movable relative to the guide portion 12. The mounting portion 22 has a fixing screw portion 22a that extends in the vertical direction. The fixing screw portion 22a is a male screw that is long in the vertical direction and is screwed into the fixing screw hole 21d. As shown in Fig. 8, the fixing screw portion 22a rotates with respect to the fixing screw hole 21d, so that the lower end 22b of the attachment portion 22 abuts against the bottom surface of the groove of the guide portion 12. Then, the base portion 21 is fixed to the mounting portion 11 by the lower end 22b of the attachment portion 22 abutting against the bottom surface of the groove of the guide portion 12. In this way, by pressing the fixing screw portion 22a against the bottom surface of the groove of the guide portion 12, the holding member 20 can be easily fixed to the mounting table 10 with a simple configuration.

[0044] 7, the connecting portion 23 is a member that is elongated in the front-rear direction and connects the base portion 21 and the support portion 24. The connecting portion 23 has a threaded portion 23a that extends along the length of the guide portion 12, a ball joint 23b for attaching the support portion 24, and a stopper 23c that prevents the threaded portion 23a from falling off the base portion 21.

[0045] The screw portion 23a is a male screw that is long in the front-rear direction and is screwed into the screw hole 21e. The connection portion 23 can adjust the position of the support portion 24 in the length direction (front-rear direction) of the guide portion 12 by rotating the screw portion 23a with respect to the screw hole 21e. Although the screw portion 23a is threaded into the upper screw hole 21e in FIG. 8, the height position of the support portion 24 can be lowered by threading the screw portion 23a into the lower screw hole 21e.

[0046] In this way, by rotating the screw portion 23a, it is possible to finely adjust the front-rear position of the support portion 24 with a simple configuration. Therefore, the force with which the support portion 24 presses the three-dimensional model M can be easily adjusted. Furthermore, by changing the position where the screw portion 23a is screwed, it is possible to finely adjust the height position of the support portion 24 with a simple configuration. Therefore, the support position can be changed finely to match the shape of the support portion 24.

[0047] Ball joint 23b is provided at the front end of threaded portion 23a and rotatably attaches support portion 24. Note that the connection between connecting portion 23 and support portion 24 is not limited to ball joint 23b, and may be a rotary joint with multiple axes as rotation centers. The stopper 23c is a member that prevents the threaded portion 23a from falling off the base portion 21, and is provided at the rear end of the threaded portion 23a.

[0048] The support part 24 is connected to the front end of the connection part 23 and supports the three-dimensional object M formed on the mounting table 10. As shown in FIG. 7, the support part 24 has a receiving part 24a that is fitted into the ball joint 23b and is rotatably attached to the connection part 23, and a contact part 24b that is attached to the receiving part 24a and comes into contact with the three-dimensional object M.

[0049] Receiving portion 24a has a cubic shape and is rotatably attached to connecting portion 23. A fitting hole into which ball joint 23b is fitted is formed on the rear surface of receiving portion 24a. The angle of receiving portion 24a is maintained by the frictional force with respect to ball joint 23b. The contact portion 24b is a long, rectangular plate-like member that is fixed to the front surface of the receiving portion 24a. An elastic member is attached to the front surface of the contact portion 24b. The elastic member is, for example, a rubber plate, and comes into contact with the surface of the three-dimensional object M. By providing the elastic member, even when the support portion 24 is pressed against the three-dimensional object M, it is possible to prevent the surface of the three-dimensional object M from being scratched.

[0050] 5, the support part 24 is attached to the connection part 23 via a ball joint 23b. The abutting part 24b abuts on the surface of the three-dimensional object M, allowing the holding member 20 to hold the three-dimensional object M. In this way, the angle of the support part 24 can be adjusted by the ball joint 23b. Therefore, even if the three-dimensional object M has a complex shape with many curved surfaces, the three-dimensional object M can be stably held by adjusting the angle of the support part 24. In particular, since each of the multiple holding members 20 is provided with the ball joint 23b, the three-dimensional object M can be held in an appropriate position even if the three-dimensional object M has a complex shape with many curved surfaces. Furthermore, since the connection part 23 of each of the multiple holding members 20 is adjustable in the front-rear and up-down directions, the three-dimensional object M can be held in an appropriate position according to its shape.

[0051] The attachment parts 22 of the holding members 20 move along the guide parts 12, so that the holding members 20 are arranged to surround the three-dimensional object M. Then, with the support parts 24 of the holding members 20 in contact with the three-dimensional object M, the position of the base part 21 is fixed by the fixing screw parts 22a. In this way, the attachment parts 22 move along the guide parts 12, so that the multiple holding members 20 can be easily switched between the normal position and the holding position. Therefore, the positions of the holding members 20 can be easily moved with a simple configuration, and the three-dimensional object M can be held at an appropriate position according to the shape of the three-dimensional object M.

[0052] With the above configuration, when the three-dimensional object M is cut on the work stage 2, the multiple holding members 20 are switched from the normal position to the holding position. In this way, the work stage 2 can be changed according to the purpose of the work. Therefore, the three-dimensional object M can be held according to the purpose of the work without moving the work location, improving work efficiency. Furthermore, since the position of the support portion 24 can be adjusted by the ball joint 23b, the three-dimensional object M can be stably held even if the three-dimensional object M has a complex curved surface. Therefore, the work space can be used for both modeling and processing, and three-dimensional objects M of various shapes can be stably held.

[0053] In this embodiment, the holding member 20 is configured to be moved manually, but the holding member 20 may also be moved automatically by the control device 9. When the movement of the holding member 20 is controlled automatically, an air drive unit or a motor drive unit for moving the holding member 20 is provided on the work stage 2.
