Description

Technical Field

[0001] This application relates to the field of 3D printing technology, and in particular to a cartridge device for a 3D printer and a 3D printer. Background Technology

[0002] 3D printing is a rapid prototyping technology that constructs three-dimensional objects by printing layer by layer based on digital model files. Its basic principle is to slice the 3D model. It's like cutting a three-dimensional object into thin, planar slices of a certain thickness (e.g., 0.1 mm, 0.2 mm, etc.). The computer sends this slice information to the 3D printer, which, based on the outline of the slices, uses nozzles and other devices to build up materials (such as plastic filaments, resin, metal powder, etc.) layer by layer to ultimately form the three-dimensional object. For example, to print a simple cube model, the printer first prints the bottom layer of the cube, then prints the second layer on top of that, and so on, until the entire cube is printed.

[0003] 3D printers use materials such as plastics, resins, and metals. Among them, resins are generally liquid resins. Liquid resins undergo a curing reaction under ultraviolet light, which allows them to print very fine details and high surface quality. They are commonly used to make models of jewelry, dental models, and other items that require extremely high precision.

[0004] Liquid resin is usually filled into a 3D printer manually so that the printer can start printing. However, manual filling of liquid resin is not only slow, but also requires manual monitoring of the liquid resin content and timely filling when needed. If the filling is not timely, it will affect the printing progress and the printing quality of the model. Utility Model Content

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0061] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0062] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0063] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium.

[0064] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0065] See Figures 1 to 8 As shown, this application provides a 3D printer, which includes a printing host (not shown), a material container 1000, and a material bottle device 2000. The printing host has a material receiving cavity configured to store printing material. The printing host can be any model of machine capable of 3D printing based on liquid resin; those skilled in the art can select a suitable machine according to actual conditions, and no limitation is made herein.

[0066] The cartridge device 1000 is configured to acquire at least the remaining height information of the printing material in the material receiving cavity. The bottle device 2000 is connected to the cartridge device 1000 and is configured to deliver printing material to the material transfer channel 1211 of the cartridge device 1000. The material transfer channel 1211 of the cartridge device 1000 is configured to deliver printing material to the material receiving cavity of the printer host.

[0067] The printing material is configured as a resin material. In one embodiment, the printing material is configured as a liquid printing material, such as liquid resin. Therefore, the liquid level detection device 1220 can be configured as a liquid level detection probe. Since the printing material is liquid resin, there is a liquid level in the material receiving cavity, which indicates the remaining amount of liquid resin stored in the material receiving cavity. Therefore, the cartridge device 1000 can be used in conjunction with the printing host to monitor the remaining amount of printing material stored in the material receiving cavity of the printing host in real time, that is, to monitor the remaining height information of the printing material in the material receiving cavity in real time. This remaining height information indicates the liquid level of the liquid resin in the material receiving cavity.

[0068] At this point, a minimum liquid level can be defined for the liquid resin in the material container cavity. When the remaining height information indicates that the liquid resin level in the material container cavity is less than or equal to this minimum liquid level, it means that the remaining storage amount of liquid resin in the material container cavity is insufficient. In this case, manual refilling of liquid resin is not required; the bottle device 2000 can automatically refill the liquid resin. When the liquid resin level in the material container cavity reaches the maximum liquid level, this can also be indicated by the remaining height information. In this case, the bottle device 2000 can stop the automatic refilling of liquid resin.

[0069] like Figures 1 to 4 As shown, regarding the aforementioned cartridge device 1000 for a 3D printer, the cartridge device 1000 may include a cartridge assembly base 1100 and a material filling mechanism 1200. The cartridge assembly base 1100 is configured to have a cartridge working position and a cartridge storage position. The material filling mechanism 1200 includes a material filling seat 1210 and a liquid level detection device 1220. The material filling seat 1210 is movably mounted on the cartridge assembly base 1100, wherein the material filling seat 1210 is configured to move between the cartridge working position and the cartridge storage position of the cartridge assembly base 1100. The material filling seat 1210 has a material transfer channel 1211 inside, which is configured to deliver printing material to the 3D printer. The liquid level detection device 1220 is assembled on the material filling seat 1210 and is configured to obtain the remaining height information of the printing material in the 3D printer.

[0070] In addition, in one embodiment, the material box device 1000 may further include a state detection mechanism 1300, which includes at least an image detection device 1310. The image detection device 1310 is mounted on the material box assembly base 1100 and is configured to acquire material image data of the printing material in the 3D printer. The image detection device 1310 can be any suitable device that can acquire material image data such as still pictures or dynamic videos, such as a camera, webcam, or video camera. Therefore, after acquiring the aforementioned material image data, various image contents of the liquid resin can be displayed in the corresponding still pictures or dynamic videos.

[0071] For example, the material image data can be configured to acquire at least the release film status information, material type information, and printing status information, thereby allowing users to remotely observe the status of the release film (including the lifespan of the release film), observe the type of liquid resin, and monitor the real-time status of the 3D printer during the printing process, thus enabling remote monitoring of the real-time working status of the 3D printer.

[0072] In one embodiment, a material box assembly chamber 1101 is formed inside the material box assembly base 1100. The material box assembly chamber 1101 may be equipped with a material transfer pipe 1400 and radio frequency identification devices, thereby providing some other auxiliary functions. For example, the material transfer pipe 1400 can be a flexible tube or a rigid tube, and the size of the material transfer pipe 1400 can be designed according to the liquid resin delivery requirements. In this case, the output port of the material transfer pipe 1400 can be connected to the material transfer channel 1211, and the input port of the material transfer pipe 1400 is configured to receive printing material. When the material transfer pipe 1400 receives printing material from the material bottle device 2000, the material transfer pipe 1400 can transport the received printing material to the material transfer channel 1211, and then transport the printing material to the 3D printer through the material transfer channel 1211, helping the 3D printer to automatically fill the liquid resin and maintain the automated operation of the 3D printer.

[0073] The radio frequency identification (RFID) device in the material box assembly chamber 1101 can be configured to identify the matching material bottle device 2000. Therefore, when the material box device 1000 is used in conjunction with different models and types of material bottle devices 2000, the RFID device can identify the different models and types of material bottle devices 2000. Thus, by identifying the different models and types of material bottle devices 2000, the type of liquid resin in the different models and types of material bottle devices 2000 can be determined, avoiding the use of the wrong type of liquid resin and preventing errors in model printing.

[0074] The material filling seat 1210 can move between the material box working position and the material box storage position of the material box assembly base 1100 in various ways, such as linear movement and fixed-axis rotation. It can be a movement of the entire body position or a movement involving angular changes, and is not limited here. For example, in one embodiment, the material filling seat 1210 has a head end and a tail end. The liquid level detection device 1220 is assembled at the head end of the material filling seat 1210, and the channel outlet of the material transfer channel 1211 is located at the head end of the material filling seat 1210. The tail end of the material filling seat 1210 is rotatably assembled to the material box assembly base 1100.

[0075] Therefore, based on the above-described fixed-axis rotation assembly method, the material filling seat 1210 can be configured to move between the material box working position and the material box storage position of the material box assembly base 1100 by rotating its tail end relative to the fixed axis of the material box assembly base 1100. That is, when the material filling seat 1210 rotates a certain angle relative to the fixed axis of the material box assembly base 1100 to a certain position, it can reach the material box working position of the material box assembly base 1100; at the same time, when the material filling seat 1210 rotates a certain angle relative to the fixed axis of the material box assembly base 1100 to another position, it can reach the material box storage position of the material box assembly base 1100.

[0076] The working position and storage position of the material box of the aforementioned material box assembly base 1100 can be either a void space or a solid position. For example, in one embodiment, the material box assembly base 1100 includes a base body 1110 and an upright body 1120. The upright body 1120 is vertically assembled to the base body 1110. The working position of the material box of the material box assembly base 1100 is located at the base body 1110, and the storage position of the material box of the material box assembly base 1100 is located at the upright body 1120. Therefore, the working position and storage position of the material box of the material box assembly base 1100 are not void positions, but solid positions determined by the base body 1110 and the upright body 1120 of the material box assembly base 1100.

[0077] The material filling seat 1210 is configured to rotate to the working position of the material box and contact the base seat portion 1110. Whether the material filling seat 1210 has rotated to the working position of the material box is determined primarily by whether the material filling seat 1210 is in contact with the base seat portion 1110. Furthermore, the material filling seat 1210 can also be configured to rotate to the material box storage position and contact the upright seat portion 1120. In this case, whether the material filling seat 1210 has rotated to the material box storage position is determined primarily by whether the material filling seat 1210 is in contact with the upright seat portion 1120.

[0078] Furthermore, the base body 1110 is provided with a working platform surface 1111, and the vertical base body 1120 is provided with a storage platform surface 1121. The working platform surface 1111 of the base body 1110 and the storage platform surface 1121 of the vertical base body 1120 have a relative planar angle. The material box working position is located on the working platform surface 1111 of the base body 1110, and the material box storage position is located on the storage platform surface 1121 of the vertical base body 1120. The material filling base 1210 has a base bottom side surface and a base top side surface facing opposite directions.

[0079] Therefore, the material filling seat 1210 can be configured to rotate to the working position of the material box, with the bottom surface of the base in contact with the working platform surface 1111. Whether the material filling seat 1210 rotates to the working position of the material box is primarily determined by whether the bottom surface of the base is in contact with the working platform surface 1111. Similarly, the material filling seat 1210 can be configured to rotate to the material box storage position, with the top surface of the base in contact with the storage platform surface 1121. Whether the material filling seat 1210 rotates to the material box storage position is primarily determined by whether the top surface of the base is in contact with the storage platform surface 1121.

[0080] In one embodiment, the relative angle between the planes is between 60° and 120°, for example, the relative angle between the planes is 90°. In other words, the fixed-axis rotation angle of the material filling seat 1210 relative to the material box assembly base 1100 is between 60° and 120°.

[0081] Continue reading Figures 5 to 8Regarding the aforementioned material bottle device 2000 for a 3D printer, the material bottle device 2000 may include a material bottle assembly base 2400, a material storage bottle 2100, a material conveying mechanism 2200, and a conveying control mechanism 2300. The material bottle assembly base 2400 has a material bottle receiving groove 2401, and the material storage bottle 2100 is movably mounted in the material bottle receiving groove 2401 of the material bottle assembly base 2400, wherein the material storage bottle 2100 is configured to store printing material. The material conveying mechanism 2200 is connected to the material storage bottle 2100, and the material conveying mechanism 2200 is configured to acquire the printing material in the material storage bottle 2100 and to convey the printing material to a matching material cartridge device 1000.

[0082] The conveying control mechanism 2300 is connected to the material conveying mechanism 2200 and is used to control the material conveying mechanism 2200 to convey printing material, that is, to control the operation and stop of the material conveying mechanism 2200, thereby realizing the conveying and stopping of printing material. The material conveying mechanism 2200 can be implemented by pumping with a liquid pump in various ways. For example, in one embodiment, the material conveying mechanism 2200 includes a material conveying pipe and a fluid driving device 2210. The fluid driving device 2210 can be a gear pump, peristaltic pump, or other types of pumps. For example, at least a section of the material conveying pipe or the entire material conveying pipe is configured as a flexible pipe, and the fluid driving device 2210 is configured as a peristaltic pump. The peristaltic pump is driven and assembled with the flexible pipe of the material conveying pipe.

[0083] At this time, the inlet of the material delivery pipe is connected to the outlet of the material storage bottle 2100, and the outlet of the material delivery pipe is configured to connect to a matching cartridge device 1000. Therefore, the fluid drive device 2210 is connected to the material delivery pipe and can be configured to drive printing material to flow from the inlet to the outlet within the material delivery pipe, thereby transporting the liquid resin in the material storage bottle 2100 along the material delivery pipe to the matching cartridge device 1000, and then via the material transfer pipe 1400 and the material transfer channel 1211 of the cartridge device 1000 to the 3D printer requiring liquid resin.

[0084] In one embodiment, the delivery control mechanism 2300 includes a control circuit board 2310, which embeds preset control logic. The control circuit board 2310 is connected to the fluid driving device 2210 and is configured to control the fluid driving device 2210 to operate or stop according to the preset control logic, thereby driving the printing material to flow in the material delivery pipe. Those skilled in the art can design this control logic according to actual needs, thereby enabling the delivery of liquid resin in a preset manner; no limitation is made here.

[0085] For example, the liquid level detection device 1220 of the material container device 1000 is configured to acquire the remaining height information of the printing material in the material receiving cavity, the conveying control mechanism 2300 of the material bottle device 2000 is connected to the material container device 1000, and the conveying control mechanism 2300 is configured to control the material conveying mechanism 2200 to convey printing material to the material container device 1000 according to the remaining height information, and the material container device 1000 is configured to convey printing material to the material receiving cavity of the printing host.

[0086] At this time, when the remaining height information indicates that the liquid resin level in the material container is less than or equal to the minimum liquid level, it means that the remaining storage amount of liquid resin in the material container is insufficient. In this case, manual refilling of liquid resin is not required. The control circuit board 2310 will control the fluid drive device 2210 to operate according to the remaining height information, transporting the liquid resin in the material storage bottle 2100 along the material delivery pipe to the matching material box device 1000, and then through the material transfer pipe 1400 and the material transfer channel 1211 of the material box device 1000 to the 3D printer that needs liquid resin. When the liquid resin level in the material container reaches the maximum liquid level, the remaining height information can also be used to indicate this. In this case, no manual operation is required. The control circuit board 2310 will control the fluid drive device 2210 to stop according to the remaining height information, thereby stopping the delivery of liquid resin.

[0087] In one embodiment, the bottle assembly base 2400 includes an assembly base portion 2410 and a support base portion 2420. The assembly base portion 2410 has a bottle assembly chamber 2402 inside. At least one of the material conveying mechanism 2200 and the conveying control mechanism 2300 is assembled in the bottle assembly chamber 2402 of the assembly base portion 2410. The support body portion 2420 is located on the side of the mounting body portion 2410. The support body portion 2420 is provided with a bottom enclosure plate 2421 and a vertical enclosure plate 2422. The bottom enclosure plate 2421 and the vertical enclosure plate 2422 are both mounted on the top surface of the support body portion 2420. The height of the vertical enclosure plate 2422 is greater than the height of the bottom enclosure plate 2421. Two supplementary enclosure plates 2423 are also provided on both sides of the vertical enclosure plate 2422. The bottom enclosure plate 2421, the vertical enclosure plate 2422 and the supplementary enclosure plates 2423 are configured to jointly enclose the bottle receiving groove 2401 on the top surface of the support body portion 2420.

[0088] In one embodiment, the assembly base 2410 is provided with a first isolation plate 2430 and a second isolation plate 2440. The first isolation plate 2430 is configured to isolate a unit isolation chamber 2431 within the bottle assembly chamber 2402.
