Description

Technical Field

[0001] The present application relates to the technical field of three-dimensional printing, and in particular to a material bottle device for a 3D printer and a 3D printer. Background Art

[0002] Three-dimensional printing (3D printing) is a rapid prototyping technology that uses digital model files as the basis to construct three-dimensional objects by printing layer by layer. The basic principle is to slice the three-dimensional model. It is like cutting a three-dimensional object into thin plane graphics according to a certain thickness (such as 0.1 mm, 0.2 mm, etc.). The computer sends these slice information to the 3D printer. The 3D printer piles up materials (such as plastic filaments, resins, metal powders, etc.) layer by layer through devices such as nozzles according to the contour information of the slices, and finally forms a three-dimensional object. For example, to print a simple cube model, the printer first prints a layer of the bottom surface of the cube, and then prints the second layer based on this layer, and so on, until the entire cube is printed.

[0003] The printing materials of 3D printers include plastic materials, resin materials and metal materials, among which resin materials are generally liquid resins. Liquid resins will undergo a curing reaction under the irradiation of ultraviolet light, so they can print very fine detail structures with high surface quality. They are usually used to make jewelry models, dental models and other items that require extremely high precision.

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

[0058] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0060] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element.

If any, 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 implementation method.

[0061] See also Figures 1 to 8 As shown, the present application provides a 3D printer, the 3D printer includes a printing host (not shown), a material box device 1000 and a material bottle device 2000, the printing host has a material holding cavity, and the material holding cavity is configured to store printing materials. Among them, the printing host is a machine of various models that can perform 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 here.

[0062] The material box device 1000 is configured to at least obtain the remaining height information of the printing material in the material containing chamber, the material bottle device 2000 is connected to the material box device 1000, the material bottle device 2000 is configured to convey the printing material to the material transfer channel 1211 of the material box device 1000, and the material transfer channel 1211 of the material box device 1000 is configured to convey the printing material to the material containing chamber of the printing host.

[0063] The printing material is configured as a resin material. In one embodiment, the printing material is configured as a liquid printing material, such as a liquid resin, so the liquid level detection device 1220 can be configured as a liquid level detection probe. Since the above-mentioned printing material is a liquid resin, there is a liquid level height of the liquid resin in the material holding chamber, and the liquid level height indicates the remaining storage margin of the liquid resin in the material holding chamber. Therefore, the material box device 1000 can be used in conjunction with the printing host, and the material box device 1000 can be used to monitor the remaining amount of the printing material stored in the material holding chamber of the printing host in real time, that is, to monitor the remaining height information of the printing material in the material holding chamber in real time. The remaining height information indicates the liquid level height of the liquid resin in the material holding chamber.

[0064] At this time, the minimum liquid level of the liquid resin in the material holding chamber can be limited. When the remaining height information indicates that the liquid level of the liquid resin in the material holding chamber is less than or equal to the minimum liquid level, it means that the remaining storage margin of the liquid resin in the material holding chamber is insufficient. At this time, there is no need to manually fill the liquid resin, and the bottle device 2000 only needs to automatically fill the liquid resin. When the liquid level of the liquid resin in the material holding chamber reaches the maximum liquid level, the remaining height information can also be used to indicate that at this time, the bottle device 2000 stops automatically filling the liquid resin.

[0065] like Figures 1 to 4 As shown, regarding the above-mentioned material box device 1000 for a 3D printer, the material box device 1000 may include a material box assembly base 1100 and a material filling mechanism 1200. The material box assembly base 1100 is configured to have a material box working position and a material box storage position. The material filling mechanism 1200 includes a material filling seat body 1210 and a liquid level detection device 1220, and the material filling seat body 1210 is movably assembled on the material box assembly base 1100, wherein the material filling seat body 1210 is configured to move between the material box working position and the material box storage position of the material box assembly base 1100. A material transfer channel 1211 is opened inside the material filling seat 1210, and the material transfer channel 1211 is configured to transport printing material to the 3D printer. The liquid level detection device 1220 is assembled on the material filling seat 1210, and the liquid level detection device 1220 is configured to obtain the remaining height information of the printing material in the 3D printer.

[0066] In addition, in one embodiment, the material box device 1000 may also include a state detection mechanism 1300, and the state detection mechanism 1300 at least includes an image detection device 1310. The image detection device 1310 is assembled on the material box assembly base 1100, and the image detection device 1310 is configured to obtain material image data of the printing material in the 3D printer. The image detection device 1310 can use various suitable devices such as cameras, webcams, and video cameras that can obtain material image data such as static pictures or dynamic videos. Therefore, after obtaining the above-mentioned material image data, various image contents of the liquid resin can be displayed in the corresponding static pictures or dynamic videos.

[0067] For example, the material image data can be configured to be used to obtain at least release film status information, material type information, and printing status information, thereby allowing the user to remotely observe the status of the release film (including the life of the release film), the type of liquid resin, the real-time status of the 3D printer during printing, etc., thereby realizing remote monitoring of the real-time working status of the 3D printer.

[0068] In one embodiment, a material box assembly chamber 1101 is opened inside the material box assembly base 1100, and a material transfer pipe 1400 and components such as a radio frequency identification device may be provided in the material box assembly chamber 1101, thereby providing some other auxiliary functions. For example, the material transfer pipe 1400 may be a hose or a hard pipe, etc., and the size of the material transfer pipe 1400 may also be designed according to the delivery requirements of the liquid resin. At this time, the output pipe mouth of the material transfer pipe 1400 may be connected to the material transfer channel 1211, and the input pipe mouth of the material transfer pipe 1400 is configured to receive printing materials. After the material transfer pipe 1400 receives the printing materials from the bottle device 2000, the material transfer pipe 1400 may transport the received printing materials to the material transfer channel 1211, and then transport the printing materials to the 3D printer through the material transfer channel 1211, so as to help the 3D printer automatically fill the liquid resin and maintain the automatic operation of the 3D printer.

[0069] The RFID device in the material box assembly chamber 1101 can be configured to identify a matching material bottle device 2000. Therefore, when the material box device 1000 is matched with material bottle devices 2000 of different models and types, the RFID device can identify the material bottle devices 2000 of different models and types. Thus, by identifying the material bottle devices 2000 of different models and types, the types of liquid resins in the material bottle devices 2000 of different models and types can be determined, thereby avoiding the wrong type of liquid resin and avoiding errors in model printing.

[0070] 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 by linear movement, fixed axis rotation and other movement modes, which can be either the movement of the entire position or the movement of angle change, which is not limited here. For example, in one embodiment, the material filling seat 1210 has a head end and a tail end, wherein 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 assembled to the material box assembly base 1100 by fixed axis rotation.

[0071] Therefore, based on the above-mentioned fixed-axis rotation assembly method, the material filling seat body 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 through the fixed-axis rotation of the tail end relative to the material box assembly base 1100. That is, when the material filling seat body 1210 is fixedly rotated by a certain angle to a certain position relative to the material box assembly base 1100, the material box working position of the material box assembly base 1100 can be reached, and at the same time, when the material filling seat body 1210 is fixedly rotated by a certain angle to another position relative to the material box assembly base 1100, the material box storage position of the material box assembly base 1100 can be reached.

[0072] The material box working position and the material box storage position of the material box assembly base 1100 described above can be either a virtual spatial position or a physical position. For example, in one embodiment, the material box assembly base 1100 includes a basic seat body portion 1110 and an upright seat body portion 1120, and the upright seat body portion 1120 is upright assembled on the basic seat body portion 1110. The material box working position of the material box assembly base 1100 is located at the basic seat body portion 1110, and the material box storage position of the material box assembly base 1100 is located at the upright seat body portion 1120. Therefore, at this time, the material box working position and the material box storage position of the material box assembly base 1100 are not virtual positions, but physical positions determined by the basic seat body portion 1110 and the upright seat body portion 1120 of the material box assembly base 1100.

[0073] The material filling seat 1210 is configured to rotate to the material box working position and contact the base seat portion 1110. At this time, whether the material filling seat 1210 rotates to the material box working position is mainly determined by whether the material filling seat 1210 contacts the base seat portion 1110. In addition, the material filling seat 1210 can also be configured to rotate to the material box storage position and contact the upright seat portion 1120. At this time, whether the material filling seat 1210 rotates to the material box storage position is mainly determined by whether the material filling seat 1210 contacts the upright seat portion 1120.

[0074] Furthermore, the base seat body 1110 is provided with a working platform surface 1111, and the upright seat body 1120 is provided with a storage platform surface 1121. There is a relative plane angle between the working platform surface 1111 of the base seat body 1110 and the storage platform surface 1121 of the upright seat body 1120. The working position of the material box is located on the working platform surface 1111 of the base seat body 1110, and the storage position of the material box is located on the storage platform surface 1121 of the upright seat body 1120, and the material filling seat 1210 has a base bottom side surface and a base top side surface facing opposite directions.

[0075] Therefore, at this time, the material filling seat body 1210 can be configured to rotate to the material box working position, and the bottom surface of the base is in contact with the working platform surface 1111. At this time, whether the material filling seat body 1210 is rotated to the material box working position is mainly determined by whether the bottom surface of the base is in contact with the working platform surface 1111. And, the material filling seat body 1210 can be configured to rotate to the material box storage position, and the top surface of the base is in contact with the storage platform surface 1121. At this time, whether the material filling seat body 1210 is rotated to the material box storage position is mainly determined by whether the top surface of the base is in contact with the storage platform surface 1121.

[0076] In one embodiment, the angle of the plane relative to the angle is between 60° and 120°, for example, the angle of the plane relative to the angle 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°.

[0077] Continue reading Figures 5 to 8Regarding the above-mentioned material bottle device 2000 for a 3D printer, the material bottle device 2000 may include a material bottle assembly base 2400, a material storage material bottle 2100, a material conveying mechanism 2200 and a conveying control mechanism 2300. The material bottle assembly base 2400 is provided with a material bottle receiving slot 2401, and the material storage material bottle 2100 is movably assembled in the material bottle receiving slot 2401 of the material bottle assembly base 2400, wherein the material storage material bottle 2100 is configured to store printing materials. The material conveying mechanism 2200 is connected to the material storage material bottle 2100, and the material conveying mechanism 2200 is configured to obtain the printing material in the material storage material bottle 2100, and to convey the printing material to the matching material box device 1000.

[0078] 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 materials, that is, to control the operation and stop of the material conveying mechanism 2200, thereby realizing the conveying of printing materials and stopping the conveying of printing materials. The material conveying mechanism 2200 can be realized by pumping of liquid pumps in various different ways. For example, in one embodiment, the material conveying mechanism 2200 includes a material conveying pipeline and a fluid driving device 2210. The fluid driving device 2210 can be a gear pump, a peristaltic pump, or other pump bodies. For example, at least a portion of the pipeline section of the material conveying pipeline or the entire material conveying pipeline is configured as a flexible pipeline, and the fluid driving device 2210 is configured as a peristaltic pump. The peristaltic pump is assembled with the flexible pipeline of the material conveying pipeline.

[0079] At this time, the input nozzle of the material delivery pipeline is connected to the output nozzle of the material storage bottle 2100, and the output nozzle of the material delivery pipeline is configured to be connected to the matching material box device 1000. Therefore, the fluid drive device 2210 is connected to the material delivery pipeline, and the fluid drive device 2210 can be configured to drive the printing material to flow from the input nozzle of the material delivery pipeline to the output nozzle of the material delivery pipeline in the material delivery pipeline, thereby delivering the liquid resin in the material storage bottle 2100 along the material delivery pipeline to the matching material box device 1000, and then delivering it to the 3D printer that needs liquid resin through the material transfer pipeline 1400 and the material transfer channel 1211 of the material box device 1000.

[0080] In one embodiment, the conveying control mechanism 2300 includes a control circuit board 2310, in which a preset control logic is embedded, and the control circuit board 2310 is connected to the fluid driving device 2210, and the control circuit board 2310 is configured to control the fluid driving device 2210 to run or stop according to the preset control logic, thereby driving the printing material to flow in the material conveying pipeline through the fluid driving device 2210. Those skilled in the art can design the control logic according to actual needs, so that the liquid resin can be conveyed in a preset manner, which is not limited here.

[0081] For example, the liquid level detection device 1220 of the material box device 1000 is configured to obtain the remaining height information of the printing material in the material holding chamber, the conveying control mechanism 2300 of the material bottle device 2000 is connected to the material box device 1000, and the conveying control mechanism 2300 is configured to control the material conveying mechanism 2200 to convey the printing material to the material box device 1000 according to the remaining height information, and the material box device 1000 is configured to convey the printing material to the material holding chamber of the printing host.

[0082] At this time, when the remaining height information indicates that the liquid resin in the material holding chamber has a liquid level less than or equal to the minimum liquid level, it means that the remaining storage margin of the liquid resin in the material holding chamber is insufficient. At this time, there is no need to manually fill the liquid resin. The control circuit board 2310 will control the operation of the fluid drive device 2210 according to the remaining height information, and the liquid resin in the material storage bottle 2100 will be transported to the matching material box device 1000 along the material delivery pipeline, and then transported to the 3D printer that needs liquid resin through the material transfer pipeline 1400 and the material transfer channel 1211 of the material box device 1000.
