DETAILED DESCRIPTION

[0036] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0037] In the technical solutions disclosed in this utility model application, unless otherwise indicated, directional terms such as "upper, lower, left, and right" are generally defined relative to the drawing orientation of the corresponding drawings, and "inner" and "outer" refer to the inside and outside relative to the outline of the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not convey order or importance. Furthermore, in the description with reference to the drawings, the same reference numerals in different drawings represent the same element.

[0038] According to the utility model application, a 3D printing device is disclosed, comprising:

[0039] refer to Figure 1 and Figure 7 As shown, the operating cabinet 1 is a vertical rectangular structure;

[0040] refer to Figure 1 、 Figure 2 、 Figure 4 As shown, the interactive mechanism 2 is provided in the operation cabinet 1 and is used to generate and confirm 3D model information;

[0041] refer to Figure 2 、 Figure 4 、 Figure 8 As shown, the 3D printer 3 is arranged in the operating cabinet 1 and is connected to the interactive mechanism 2 via signals;

[0042] refer to Figure 2 、 Figure 4 、 Figure 8As shown, the model container 4 is provided in the operating cabinet 1 at the upper end of the 3D printer 3 and is used to place the printed 3D model;

[0043] refer to Figure 2 、 Figure 4 、 Figure 8 As shown, the conveying mechanism 5 is provided in the operating cabinet 1 and is used to convey the printed 3D model;

[0044] refer to Figure 2 、 Figure 4 、 Figure 8 As shown, the operating cabinet 1 is provided with an operating cabinet door 101 , and an observation window 101 b for observing the 3D printer 3 and the model container 4 is formed on the operating cabinet door 101 .

[0045] In the above technical solution, the operator or user first uses the interactive mechanism 2 to confirm the data model of the 3D printed product to be printed, and then uses the signal connection between the interactive mechanism 2 and the 3D printer 3 (the signal connection can be a wired connection or a wireless connection) to transmit the product model information to the 3D printer 3. The 3D printer 3 prints, and after confirming that the product has been printed successfully, the 3D printed product is transported by the transport mechanism 5 and finally taken out.

[0046] The data model of 3D printing products can be confirmed in the following ways:

[0047] ① After the user inputs instructions such as hand-drawn sketches, voice, text, pictures, videos, etc. on the interactive mechanism 2, the interactive mechanism 2 is used to preliminarily generate, preview, modify, and finally confirm the model of the 3D printed product;

[0048] ② Users can use the free / paid database on the interactive mechanism 2 to select their own model, preview, modify, and finally confirm;

[0049] ③ The user can take photos in real time and transmit the photos to the interactive mechanism 2, and use the interactive mechanism 2 to preliminarily generate, preview, modify, and finally confirm the model of the 3D printed product.

[0050] Specifically, the operator can interact with interactive mechanism 2 using the device's built-in interactive equipment or through a user's own mobile device. After interactive mechanism 2 is linked to a 3D model generation program or website via an APT key, the operator can input model generation instructions on interactive mechanism 2, which are then sent to the program or website. After the program or website generates the 3D model, the model data is returned to interactive mechanism 2. Model generation instructions include, but are not limited to, text, voice, hand-drawn sketches, images, and videos.

[0051] To sum up, this solution overcomes the interaction problems between users and 3D printing devices, and achieves the technical effects of reducing user operation difficulty, lowering the threshold for using 3D printing technology, simplifying the 3D model production process, and improving the printing efficiency of 3D products. It enables the application of 3D printing technology to be extended to more industries and fields, so as to realize the application and promotion of 3D printing technology in the mass consumer field, so that 3D printing technology can not only be used in consumer markets such as mass leisure and entertainment, but can also be widely used in various links from research and development to production in the industrial field, etc., and ultimately achieve the goal of promoting social and economic development and enriching the cultural and entertainment life of the masses.

[0052] In this embodiment, if Figure 1 As shown, the interactive mechanism 2 includes a QR code 201, which is set on the outer end surface of the operating cabinet door 101. This solution is to interact with the user's own mobile device, specifically: the user scans the QR code 201 on the operating cabinet door 101 to enter the relevant application or the corresponding applet of the application.

[0053] Specifically, the application is a common software that can realize interactive functions commonly found in the application market. In short, it can realize access to the 3D model generation website and can realize simple integration functions.

[0054] The operator uploads the relevant hand-drawn sketches, voice, text, pictures, and videos stored in the mobile phone to the mini program, or selects an existing model in this mini program. The mini program then links to the website for 3D model generation through the API key to perform preliminary generation of the 3D model. The operator then previews, modifies, and confirms the model on his or her own mobile device, connects to the 3D printer 3 through the mini program, and finally successfully completes the 3D printing product.

[0055] In this embodiment, if Figure 4 As shown, a rectangular frame 101a is formed on the upper end of the operating cabinet door 101;

[0056] like Figure 1 、 Figure 2The interactive mechanism 2 includes a tablet computer 202, which is embedded in the rectangular frame 101a and can slide up and down. This design is to interact with the interactive device of the device, specifically: the corresponding application is installed on the tablet computer 202 on the operating cabinet door 101, and the operator uploads the hand-drawn sketches, voice, text, pictures, and videos related to the product to be printed to the application. The application can be linked to the relevant 3D model generation website or software through the API key, and the hand-drawn sketches, voice, text, pictures, and videos uploaded by the user on the tablet computer 202 are transmitted to the 3D model generation website or software. The website or software then generates the corresponding 3D model or selects the 3D model already in the database of this application. The operator then previews, modifies, and confirms the 3D model on the tablet computer 202. At the same time, the tablet computer 202 is connected to the 3D printer 3 signal. After the 3D model is confirmed, the operator directly selects to print, and the production of the 3D printed product is completed. In some specific embodiments, the tablet computer 202 can be slid up and down and embedded in the rectangular frame 101a. This design allows the operator to adjust the tablet computer 202 to a height that suits him or her according to his or her own situation, so that the operator can operate in the most comfortable environment, which is a more humane design.

[0057] In this embodiment, if Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a side top plate 103 is provided on the outside of the top of the operating cabinet 101, and a column 104 is vertically fixed to the lower end surface of the side top plate 103, and the column 104 plays the role of supporting the side top plate 103; the interactive mechanism 2 includes an acquisition device 203, and the acquisition device 203 is respectively installed at the four corners of the lower end surface of the side top plate 103. This design allows users or operators to generate 3D printing product data models by taking real-time photos. Usually, the photos taken are transmitted to a tablet computer 202, and the tablet computer 202 is used to preliminarily generate, preview, modify, and finally confirm the model of the 3D printing product. In some specific embodiments, the acquisition device 203 is four sampling cameras, which are respectively installed at the four corners of the lower end surface of the side top plate 103. The sampling cameras take photos from four different directions. The model generated in this way is more accurate, vivid, and three-dimensional.

[0058] In this embodiment, if Figure 2 、 Figure 4 、 Figure 5 As shown, the transmission mechanism 5 includes:

[0059] A first conveying platform 501 is located on one side of the 3D printer 3 and a first conveying belt 501a is installed on the first conveying platform 501;

[0060] The first sensor 502 is installed on the upper end surface of the first conveyor platform 501 on one side of the first conveyor belt 501a;

[0061] A pair of first sliding bars 6 are respectively mounted on the left and right ends of the lower end surface of the first conveying platform 501, and the two first sliding bars 6 are fixedly connected by a first connecting plate 7;

[0062] A first cylinder 8, the top of the telescopic rod of the first cylinder 8 is fixedly connected to the first connecting plate 7, and is used to drive the lifting of the first conveying platform 501;

[0063] The horizontal rod 503 is installed in the operating cabinet 1 above the 3D printer 3 and the first conveying platform 501;

[0064] The slider 504 is slidably mounted on the horizontal rod 503 , and a vertically retractable sling 505 is mounted on the lower end of the slider 504 . The sling 505 can be a lifting claw, an electromagnetic suction cup, or the like.

[0065] In the above technical solution, the specific operation method is as follows: after the 3D printer 3 completes printing, the 3D printed product is placed in the model container 4. The model container 4 is lifted by the slider 504 via the sling 505 at its lower end. The slider 504 uses the positional relationship between the horizontal rod 503 and the first conveyor platform 501 to lift the 3D printed product from the 3D printer 3 to the first conveyor platform 501. (Regarding the slider 504, its internal components include: a motor, a worm gear, and several pulleys, which are prior art and will not be repeated here.) In particular, because the first cylinder 8 drives the lifting of the first conveyor platform 501, the operator can adjust the height of the first conveyor platform 501 according to the required conveying height. When the model container 4 is placed on the first conveyor belt 501a of the first conveyor platform 501, the first sensor 502 recognizes the presence of an object on the first conveyor belt 501a. The first conveyor platform 501 then starts to operate, and the first conveyor belt 501a rotates until the model container 4 above it is transported to the designated location, where the operator removes the 3D printed product. In other embodiments, the first cylinder 8 can be replaced with another lifting device, such as a hoist, as long as it can perform the lifting function.

[0066] In this embodiment, if Figure 3 、 Figure 5 As shown, the lifting device 505 is an electromagnetic suction cup. When in use, the electromagnetic suction cup can be used by powering it on. Compared with using a lifting claw to lift the product, the electromagnetic suction cup is safer and more stable, ensuring that the product is not easy to fall off.

[0067] In this embodiment, if Figure 5As shown, two vertical first guide slots 102 are formed on the inner wall of the operating cabinet 1 at the rear side of the first conveyor platform 501; the rear ends of the two first slide bars 6 are slidably mounted in the two first guide slots 102. The first guide slots 102 provide guidance for the first conveyor platform 501, ensuring that the first conveyor platform 501 remains vertically raised and lowered without tilting or deviating while the operator is adjusting the first conveyor platform 501 by using the first cylinder 8.

[0068] Furthermore, in some other embodiments, such as Figure 2 、 Figure 4 、 Figure 6 As shown, the operation cabinet 1 further includes a storage unit 9 for storing 3D models, and the storage unit 9 includes:

[0069] A plurality of second conveying platforms 901 are located adjacent to the first conveying platform 501. The plurality of second conveying platforms 901 are vertically fixed on the rear inner wall of the operating cabinet 1 at intervals from top to bottom. Each second conveying platform 901 is equipped with a second conveyor belt 901a.

[0070] A plurality of second sensors 902 are respectively installed on the upper end surface of the second conveying platform 901 on one side of each second conveyor belt 901a;

[0071] A cabinet door 105 is provided at a position of the operating cabinet 1 corresponding to the second conveying platform 901 .

[0072] In the above technical solution, after the first conveyor platform 501 is raised to the required height by the first cylinder 8 (the required height here refers to being flush with one of the second conveyor platforms 901), the first sensor 502 recognizes the model container 4 on the first conveyor belt 501a, and the first conveyor belt 501a and the second conveyor belt 901a both start to rotate. The first conveyor belt 501a will convey the model container 4 and the 3D printed product in the model container 4 to the second conveyor belt 901a until the second sensor 902 recognizes the 3D printed product placed above the second conveyor belt 901a. At this time, the first conveyor belt 501a and the second conveyor belt 901a both stop rotating. At this time, the model container 4 and the 3D printed product will be stationary on the second conveyor platform 901, waiting for the operator to open the cabinet door 105 and take out the product. Since the device is provided with a storage unit 9, the operator or user can take out the product at a convenient time. They can also print online and pick up the product offline or even directly pick it up from the delivery platform and have it delivered to their door. This design increases the convenience of use. In addition, the cabinet door 105 can be a split type or an integrated design, which is not specifically limited here.

[0073] In other embodiments, Figure 7 、 Figure 8As shown, the upper end of the operating cabinet door 101 is provided with a pickup window 101c;

[0074] The conveying mechanism 5 includes: a third conveying platform 506 , located at the bottom end surface of the 3D printer 3 , for supporting and lifting the 3D printer 3 ;

[0075] A pair of third sliding bars 12 are respectively mounted on the left and right ends of the lower end surface of the third conveying platform 506, and the two third sliding bars 12 are fixedly connected by a third connecting plate 11;

[0076] The third cylinder 10, the top of the telescopic rod of the third cylinder 10 is fixedly connected to the third connecting plate 11, and is used to drive the lifting of the third conveying platform 506.

[0077] In the above technical solution, the interactive mechanism 2 includes a QR code 201 on the outer end of the operating cabinet door 101. After the operator scans the code to confirm the model data, the 3D printer 3 is used to print the product. The operator then uses the third cylinder 10 to raise the third conveyor 506 to the height of the pickup window 101c and remove the 3D printed product from the model container 4. In this solution, the interactive mechanism 2 does not include a tablet computer 202, which makes installation more convenient and a simple design. Figure 9 As shown, two vertical second guide slots 106 are formed on the inner wall of the operating cabinet 1 behind the third conveyor platform 506; the rear ends of the two third slide bars 12 are slidably mounted in the two second guide slots 106. This design serves a similar purpose to the first guide slots 102: to guide the third conveyor platform 506 and ensure that the third conveyor platform 506 remains vertically raised and lowered without tilting or deviating during the process of the third cylinder 10 adjusting the third conveyor platform 506.

[0078] This utility model application exemplarily describes the steps for installing a 3D printing device, which are as follows:

[0079] S1. The operator uses the corresponding application installed on the tablet computer 202 to input text related to the product to be 3D printed into the application;

[0080] S2. After the operator generates, previews, modifies, and finally confirms the 3D printed product on the tablet computer 202, the operator uses the 3D printer 3 to print the product;

[0081] S3. After the operator confirms that the product has been successfully printed, the model container 4 containing the 3D printed product is lifted onto the first conveyor platform 501 using an electromagnetic chuck. The model container 4 is then conveyed to the second conveyor platform 901 using the first conveyor belt 501a and the second conveyor belt 901a. When the second sensor 902 recognizes that the 3D printed product is placed above the second conveyor belt 901a, the first conveyor belt 501a and the second conveyor belt 901a stop rotating, and the model container 4 and the 3D printed product remain stationary on the second conveyor platform 901.

[0082] S4. The operator opens the cabinet door 105, takes out the product, and proceeds to produce the next 3D printed product.

However, the present application is not limited to the specific details of the above embodiments. Within the scope of the disclosed technical concept, various simple variations can be made to the technical solution of the present utility model application, and these simple variations all fall within the scope of protection of the present application.
