[0099] The photocuring 3D printing technology selectively cures the photosensitive resin layer by layer by controlling the light source, and controls the vertical displacement of the platform to cure the next layer of photosensitive resin on the previous cured layer, thereby completing the production of the printed model.

[0100] The 3D printing platform is generally a rigid metal platform. There is a certain degree of adhesion between the model and the 3D printing platform. After printing, there will be difficulties in separation. Forced separation will often damage the model.

[0101] In the related art, after printing is completed, the entire metal platform needs to be removed, and then the printed parts on the metal platform need to be shoveled off with a shovel, which is time-consuming and laborious, and may easily cause personal injury.

[0102] The following describes the 3D printing platform, model removal device and 3D printing equipment provided by the embodiments of the present invention with reference to the accompanying drawings.

[0103] refer to Figure 1 and Figure 2 As shown, the utility model provides a 3D printing platform, including: a support table 10, the support table 10 includes a lower cover plate 14 for connecting the printing model, and a heating element 12 connected to the lower cover plate 14, the heating element 12 is configured to heat the lower cover plate 14, and the side of the lower cover plate 14 facing away from the heating element 12 is used to connect the printing model.

[0104] The utility model provides a 3D printing platform, which is used to connect the printing model during the 3D printing process. Since the support platform 10 includes a lower cover plate 14 for connecting the printing model and a heating element 12 connected to the lower cover plate 14, the heating element 12 is used to heat the lower cover plate 14, so that the temperature of the lower cover plate 14 is increased, which can reduce the viscosity between the printing model and the lower cover plate 14, thereby helping to reduce the difficulty of removing the printing model, saving time and effort, and improving production efficiency.

[0105] In a possible implementation, the 3D printing platform further includes an upper cover plate 13 , the heating element 12 is disposed between the upper cover plate 13 and a lower cover plate 14 , and the heating element 12 is attached to the lower cover plate 14 .

[0106] In one possible implementation, the heating element 12 includes but is not limited to a silicone heating plate and a ceramic heating plate. On the one hand, it can quickly increase the temperature of the upper cover plate 13 and the lower cover plate 14, thereby reducing the viscosity between the printed model and the lower cover plate 14. On the other hand, it can play an insulating and protective role to improve safety of use.

[0107] In one possible implementation, reference Figure 3 and Figure 4 As shown, an accommodating cavity 11 is formed between the upper cover plate 13 and the lower cover plate 14 , and the heating element 12 is located in the accommodating cavity 11 and is attached to the lower cover plate 14 to prevent the heating element 12 from being exposed, thereby protecting the heating element 12 and avoiding scalding the user.

[0108] The lower cover plate 14 may be rectangular in shape and may be made of metal, such as a steel plate. The heat permeability of the lower cover plate 14 is used to heat the attached printed model, thereby achieving an efficient and rapid effect of removing the printed model.

[0109] In one possible implementation, reference Figure 5 and Figure 6As shown, the 3D printing platform also includes a docking joint 15, which is arranged on the support platform 10, and the docking joint 15 is provided with a first joint 42, the first joint 42 is electrically connected to the heating element 12, and the first joint 42 is used to be electrically connected to an external power supply device to heat the printed model. Specifically, the docking joint 15 can be fixed on the upper cover plate 13, and the docking joint 15 is connected to the support platform 10 through the upper cover plate 13.

[0110] The 3D printing platform provided by the utility model has good versatility and can be used in 3D printing equipment as a printing platform connected to a printed model. In this case, the first connector 42 is used to electrically connect to the 3D printing equipment. In addition, the 3D printing platform provided by the utility model can also be used in the model removal device provided by the utility model. In this case, the first connector 42 is connected to the second connector 43 of the model removal device to achieve electrical connection.

[0111] refer to Figure 7 and Figure 8 As shown, the utility model also provides a model removal device, which is used to remove the printed model from the above-mentioned 3D printing platform. The model removal device includes a detachment component 30, and the 3D printing platform is detachably arranged on the detachment component 30. The detachment component 30 includes a scraper 31, and the scraper 31 is configured to push the printed model along a first direction so that the printed model is separated from the 3D printing platform.

[0112] The utility model also provides a model removal device, under the pushing action of the scraper 31 on the printing model, the printing model is moved relative to the support table 10, so that the printing model is detached, making the removal operation of the printing model very convenient, saving time and effort.

[0113] In one possible implementation, the model dismantling device also includes a second connector 43, which is used to be detachably electrically connected to the heating element 12 of the 3D printing platform. Specifically, the second connector 43 can be detachably electrically connected to the heating element 12 through the first connector 42. The second connector 43 is used to be electrically connected to the heating element 12 when the 3D printing platform is fixed on the detachment component 30, so that the heating element 12 heats the lower cover plate 14 of the 3D printing platform.

[0114] refer to Figure 2 and Figure 8 As shown, the utility model provides a model removal device. Under the heating effect of the heating element 12 on the lower cover plate 14, the viscosity between the printed model and the lower cover plate 14 is reduced, and the printed model becomes loose relative to the lower cover plate 14. Combined with the action of the detachment component 30, the scraper 31 pushes the printed model, so that the printed model can be separated from the lower cover plate 14, and the removal operation of the printed model is more convenient.

[0115] The first direction is a direction parallel to the lower surface of the lower cover plate 14. In this embodiment, the first direction refers to Fig. 9 The arrow X indicates the direction.

[0116] In a possible implementation, the model disassembling device further includes a bracket 20, and the detaching assembly 30 is disposed on the top of the bracket 20. The bracket 20 is used to support the detaching assembly 30.

[0117] In one possible implementation, reference Figure 8 and Fig. 9 As shown, the detachable assembly 30 includes: a mounting shell 32 and a driving unit 33. The mounting shell 32 is connected to the top of the bracket 20. The mounting shell 32 has a mounting cavity 321 inside. The center of the mounting shell 32 is surrounded by a hollow cavity 322. The 3D printing platform is detachably arranged in the hollow cavity 322. The driving unit 33 is connected to the scraper 31 and is used to drive the scraper 31 to reciprocate along the first direction. The hollow cavity 322 is used to accommodate the 3D printing platform.

[0118] In a possible implementation, the mounting shell 32 includes a bottom shell 324 and a top cover 325, and the top cover 325 is buckled on the bottom shell 324 to enclose a mounting cavity 321 between the bottom shell 324 and the top cover 325, and the mounting cavity 321 is used to install the drive unit 33. The mounting cavity 321 can be a circumferential arrangement surrounding the hollow cavity 322, and the hollow cavity 322 is used to accommodate the printing model.

[0119] The 3D printing platform can be placed in the hollow cavity 322. At least two side edges of the hollow cavity 322 have sunken steps 326. The edge of the lower cover plate 14 of the support platform 10 is placed on the sunken steps 326 to limit the position of the 3D printing platform, so that the 3D printing platform can be more conveniently placed in the hollow cavity 322.

[0120] The driving unit 33 is used to drive the scraper 31 to reciprocate along the first direction, so that the scraper 31 pushes the printed model, and the scraper 31 resets to prepare for the next push of the printed model.

[0121] In other possible implementations, the scraper 31 may be moved along the first direction under manual pushing action, so that the scraper 31 pushes the printed model.

[0122] In one possible implementation, reference Figure 8 and Fig. 9As shown, the drive unit 33 is arranged in the installation cavity 321. The drive unit 33 includes: a screw nut transmission mechanism and a motor 334. The screw nut transmission mechanism includes a connecting frame 331, a screw 332 and a nut 333.

The scraper 31 is connected to the nut 333. The motor 334 is arranged on the connecting frame 331, and the output shaft of the motor 334 is connected to one end of the screw 332 and is used to drive the screw 332 to rotate.

[0123] In this embodiment, the motor 334 drives the lead screw 332 to rotate. During the rotation of the lead screw 332, the nut 333 drives the scraper 31 to move along the axial direction of the lead screw 332, thereby enabling the scraper 31 to push the printed model, making it easier for the printed model to detach from the support table 10, saving time and effort.

[0124] The motor 334 may be connected to the outer side of the connecting frame 331 via fasteners, and the fasteners include but are not limited to screws, bolts, etc.

The motor 334 can be connected to the outer wall surface of the first connecting block 3311 or the second connecting block 3312.

[0126] In order to improve the stability of the connecting frame 331, the connecting frame 331 further includes a crossbeam 3313, and both ends of the crossbeam 3313 are respectively connected to the outer side walls of the first connecting block 3311 and the second connecting block 3312, so that the connecting frame 331 becomes an integral structure.

[0128] In this embodiment, by setting two screw-nut transmission mechanisms, the two ends of the scraper 31 are respectively connected to the nuts 333 of the two screw-nut transmission mechanisms, which improves the stability of the scraper 31 in pushing the printed model, helps to improve the force uniformity of the scraper 31, and ensures the service life of the scraper 31.

[0129] In this embodiment, through the transmission belt mechanism, only one motor 334 is needed to drive the two screw nut transmission mechanisms to move synchronously, and the diameters of the first pulley and the second pulley are consistent, ensuring that the movement speeds on both sides of the scraper 31 are consistent, which is beneficial to prevent the scraper 31 from tilting or even getting stuck, thereby ensuring the use effect.

The guide block 342 moves along the axial direction of the guide rod 341, and guides the nut 333 to move along the lead screw 332.

[0132] The axial direction of the guide rod 341 is consistent with the axial direction of the lead screw 332 , and both ends of the guide rod 341 may be respectively fixed to the first connecting block 3311 and the second connecting block 3312 , and the axial direction of the guide rod 341 is spaced apart from the lead screw 332 .
