[0045] See Figure 1 As shown, this application provides a 3D printer, which includes a printing device for outputting printed models and a model transport platform 100 for carrying the printed models. The model transport platform 100 is configured to enable continuous printing by the 3D printer, thereby improving printing efficiency. (Continue reading...) Figure 2 As shown, the aforementioned model transfer platform 100 includes a heated bed 1000 and a transfer device 2000. The transfer device 2000 is used to carry and transfer the printed model, such as... Figure 2 As shown, the conveying device 2000 includes a drive assembly 2100 and a conveyor belt 2200. The conveyor belt 2200 is movably wound around the heated bed 1000. The drive assembly 2100 is driven to the conveyor belt 2200, and can drive the conveyor belt 2200 to rotate along a predetermined conveying direction. Through the rotation of the conveyor belt 2200, different belt regions of the conveyor belt 2200 dynamically and continuously pass over the surface of the heated bed 1000. Therefore, this application specifies that the belt region of the conveyor belt 2200 passing over the surface of the heated bed 1000 is configured as a printing area, and then this printing area is used to support the printed model. It should be noted that the above-mentioned printing area is dynamically changing. During the continuous rotation of the conveyor belt 2200, different belt regions of the conveyor belt 2200 will form the above-mentioned printing area, thereby realizing the operation of the printed model and achieving continuous 3D printing.

[0046] Continue reading Figure 2As shown, in this application, the conveyor belt 2200 is defined with a unit rotation distance 2201 along a predetermined conveying direction. This unit rotation distance 2201 is a portion of the total rotation length of the conveyor belt 2200. The purpose of this unit rotation distance 2201 is to limit the distance of rotation required after a single printing of the printed model, so that the printed model can be successfully moved out and a new printing area can be formed. At this time, the drive component 2100 is connected to the conveyor belt 2200 and can be used to drive the conveyor belt 2200 to rotate relative to the heated bed 1000 according to the unit rotation distance 2201. Thus, after the previous printing is completed, by moving the unit rotation distance 2201, the printed model is moved out from the previous so-called printing area and a new printing area is formed on the heated bed 1000 for the next printing of the model.

[0047] The heated bed 1000 is used to heat the conveyor device 2000, increasing the adhesion of the first layer during 3D printing and preventing abnormalities such as warping and bulging during the printing process. In one embodiment, the heated bed 1000 can also be equipped with several magnetic components as needed, and these components are distributed on the heated bed 1000 in a suitable manner. Correspondingly, the conveyor belt 2200 is made of a magnetically attractive material, thereby enabling the heated bed 1000 to magnetically attract the printing area of ​​the conveyor belt 2200, ensuring a tight fit between the printing area and the heated bed 1000, thus replacing the traditional printing plate. The conveyor belt 2200 is made of steel or polyvinyl chloride, such as cold-rolled steel plate, stainless steel plate, spring steel plate, and other high-temperature resistant materials.

[0048] The drive assembly 2100 of the conveyor 2000 can be a roller motor, a motor with a chain and sprocket, a motor with a belt, or a direct-drive motor, for example. Figure 2 As shown, the drive assembly 2100 may include a drive wheel 2110 and a driven wheel 2120. A motor drives the drive wheel 2110 to rotate, and the drive wheel 2110 drives the driven wheel 2120 to rotate via a conveyor belt 2200. At this time, the conveyor belt 2200 is wound between the drive wheel 2110 and the driven wheel 2120. The heated bed 1000 is also located between the drive wheel 2110 and the driven wheel 2120. The conveyor belt 2200 rotates. If the direction from the drive wheel 2110 to the driven wheel 2120 is defined as a predetermined conveying direction, the conveyor belt 2200 can achieve separation of the bottom of the printed model from the conveyor belt 2200 by bending at the driven wheel 2120, thereby achieving automatic separation of the printed model from the conveyor belt 2200. After the printed model is conveyed out of the printing area, the conveyor belt 2200 will re-form a new printing area so that the 3D printer can perform continuous printing in the new printing area.

[0049] In one embodiment, the model transport platform 100 may further include a positioning mechanism 3000, the function of which is to locate the unit rotation distance 2201 of the conveyor belt 2200 relative to the heated bed 1000. The unit rotation distance 2201 may be defined as greater than or equal to the maximum length of the heated bed 1000 in the transport direction. For example, in one embodiment, the unit rotation distance 2201 is configured to be 1 to 1.5 times the maximum length of the heated bed 1000 in the transport direction, such as 1, 1.1, 1.2, 1.3, 1.4, 1.5, etc.

[0050] At this time, the drive component 2100 can be used in conjunction with the positioning mechanism 3000. When the positioning mechanism 3000 performs its positioning function and positions the unit rotation distance 2201 of the conveyor belt 2200, the drive component 2100 can control the rotational movement of the conveyor belt 2200 according to the positioned unit rotation distance 2201. For example, it can control the conveyor belt 2200 to move only the unit rotation distance 2201 each time, move the printed model out, and re-form a new printing area.

[0051] In one embodiment, the positioning mechanism 3000 includes a positioning identification unit 3100 and a positioning identifier 3200. The number of positioning identification units 3100 is configured to be several, and the several positioning identification units 3100 are distributed along the conveying direction of the conveyor belt 2200. The distance between adjacent positioning identification units 3100 is used to form a unit rotation distance 2201. The positioning identifier 3200 is used to identify the positioning identification units 3100. Therefore, when the conveyor belt 2200 rotates, once the positioning identifier 3200 continuously identifies two adjacent positioning identification units 3100, it can be determined that the distance between the two adjacent positioning identification units 3100 is one unit rotation distance 2201 traveled by the conveyor belt 2200.

[0052] Both the positioning identification unit 3100 and the positioning identifier 3200 can adopt various structural forms and sensor forms. For example, in one embodiment, the positioning identification unit 3100 can be configured to be opened in the identification slot of the conveyor belt 2200. In this case, the positioning identifier 3200 is configured to identify the identification slot. Alternatively, the positioning identifier 3200 can be configured to use a photoelectric sensor, in which case the photoelectric sensor can be used to identify the positioning identification unit 3100 in the form of, for example, an identification slot.

[0053] Based on the cooperation of the positioning mechanism 3000 and the conveying mechanism, the 3D printer begins to print the model. After the first model is printed, the drive wheel 2110 rotates to drive the conveyor belt 2200 to rotate, first conveying the first model out of the printing area on the heated bed 1000. At the exit end of the printing area, the first model is peeled off from the conveyor belt 2200 in cooperation with the peeling mechanism 4000.

[0054] When the positioning mechanism 3000 detects the next positioning recognition unit 3100 set on the conveyor belt 2200, the drive wheel 2110 and the conveyor belt 2200 stop rotating. At this time, a new printing area is formed on the conveyor belt 2200, and the 3D printer continues to print the model. In this way, the 3D printer can achieve continuous printing of the model without human operation or intervention.

[0055] Continue reading Figure 2 As shown, in one embodiment, the conveying device 2000 includes a device base 2300, which serves as the assembly base for the heated bed 1000 and the conveying mechanism on the conveying device 2000. Therefore, the device base 2300 can adopt various suitable structures such as a frame structure, a bracket structure, a seat structure, or a shell structure, which are not limited here. At this time, the drive assembly 2100 and the heated bed 1000 can be assembled on the device base 2300. The device base 2300 can define a conveying area 2202, in which cavities and recesses can be formed for assembling the heated bed 1000, so that the heated bed 1000 can be located within the conveying area 2202. The conveyor belt 2200 is movably assembled on the conveying area 2202 of the device base 2300, thereby being movably wound around the heated bed 1000.

[0056] For example, the device base 2300 can be composed of two symmetrically arranged frame members, and a conveying area 2202 for winding the conveyor belt 2200, assembling the heated bed 1000, and the conveying mechanism can be formed between the two symmetrically arranged frame members. The relative positions of the two symmetrically arranged frame members can be maintained by limiting structures such as limiting posts, thereby enhancing the stability of the overall structure.

[0057] In one embodiment, the conveying device 2000 may further include a support plate 2400, wherein, as Figure 2As shown, the surface area of ​​the heated bed 1000 is smaller than the area of ​​the conveying area 2202 of the device base 2300. Therefore, there is an empty area in the conveying area 2202 where the heated bed 1000 and other cooperating structures are not installed. Since the empty area will cause the conveyor belt 2200 to be unsupported at this location, the support plate 2400 can be installed in the conveying area 2202 to cover at least a portion of the empty area, thereby providing support for the bottom of the conveyor belt 2200 and preventing the printed model from collapsing or deforming in the empty area when gravity is applied to the conveyor belt 2200.

[0058] The conveying device 2000 may also include a limiting component 2500, which is mounted on the device base 2300. The limiting component 2500 is used to restrict the movement of the conveyor belt 2200 within the conveying area 2202 of the device base 2300, preventing it from exceeding the conveying area 2202. The limiting component 2500 may have a strip-shaped or sheet-shaped structure and be arranged along the conveying direction of the conveyor belt 2200. For example, two limiting components 2500 may be respectively provided on both sides of the conveyor belt 2200. The two limiting components 2500 not only limit the movement of the conveyor belt 2200, but also provide safety protection to prevent the side edges of the conveyor belt 2200 from causing injury to people.

[0059] The conveying device 2000 may further include a support member 2600, which is disposed on the device base 2300, and the heated bed 1000 is assembled to the device base 2300 via the support member 2600. For example, a plurality of support members 2600 may be used, which are connected to the heated bed 1000 at different positions and connect the heated bed 1000 to the device base 2300.

[0060] In one embodiment, the model transport platform 100 includes a peeling mechanism 4000. The printing area of ​​the conveyor belt 2200 has an infeed end and an outfeed end formed along the transport direction. The peeling mechanism 4000 is located at the outfeed end of the printing area. Therefore, when the printed model is removed from the outfeed end of the conveyor belt 2200, the peeling mechanism 4000 can actively apply a peeling force relative to the conveyor belt 2200 to the printed model, thereby separating the printed model from the printing area of ​​the conveyor belt 2200. The peeling mechanism 4000 can employ a structure such as a scraper capable of separating the printed model from the conveyor belt 2200, for example, as... Figure 2 As shown, the scraper is set at the exit end of the conveyor belt 2200. The printed model can be transported to the exit end with the rotation of the conveyor belt 2200. Under the combined action of the bending stress of the conveyor belt 2200 and the scraper, the printed model can be automatically detached.

[0061] The model conveyor platform 100 may also include a tensioning mechanism 5000, which is connected to the conveyor device 2000. For example, the tensioning mechanism 5000 may be located at the exit end or other position of the conveyor device 2000. The purpose of the tensioning mechanism 5000 is to adjust the tension of the conveyor belt 2200 to ensure that the conveyor belt 2200 rotates under the expected or appropriate tension. The tensioning mechanism 5000 can be adopted in various forms according to actual needs. For example, the tension of the conveyor belt 2200 can be adjusted by means of screws, springs, pneumatics, hydraulics, etc.

[0062] like Figure 4 As shown, in one embodiment, when the drive assembly 2100 uses a drive wheel 2110 and a driven wheel 2120, a sliding portion 5100 can be formed by milling, for example, the end of the shaft of the driven wheel 2120. The sliding portion 5100 has a threaded hole in a direction perpendicular to the axial direction of the driven wheel 2120. The device base 2300 of the conveying device 2000 can be provided with a sliding groove 5200 at an appropriate mating position. The sliding portion 5100 is slidably installed in the sliding groove 5200. By sliding the sliding portion 5100 relative to the sliding groove 5200, the distance between the drive wheel 2110 and the driven wheel 2120 can be adjusted, thereby adjusting the tension of the conveyor belt 2200.

[0063] Simultaneously, through holes are machined at both ends of the sliding groove 5200, and clearance grooves 5300 are machined at the ends of the through holes. Tension adjustment components 5400, such as tension adjustment screws, are installed inside the through holes. The tension adjustment component 5400 is threadedly connected to the sliding part 5100. By adjusting the position of the sliding part 5100 within the sliding groove 5200, the left and right positions of the driven wheel 2120 are adjusted, thereby adjusting the tension of the conveyor belt 2200. After adjustment, the tension adjustment component 5400 is screwed down, and the adjusting nut 5500 and the tension adjustment component 5400 are connected and fixed within the clearance groove 5300, locking the position of the sliding part 5100 within the sliding groove 5200.

[0064] In addition, those skilled in the art may use other specific adjustment methods to adjust the tension of the conveyor belt 2200 according to actual needs, which are not limited here.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
