[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] like Figures 1 to 3As shown, an embodiment of the utility model provides a platform assembly with a leveling mechanism, which includes a base 10, a mounting plate 20, an elastic member 40, an adjusting member 50, a platform fixing frame 02 and a forming platform 03 connected to each other. The mounting plate 20 is located on one side of the base 10, and there is an adjustment gap between the mounting plate 20 and the base 10. The elastic member 40 is arranged between the base 10 and the mounting plate 20 to provide a force to move the base 10 and the mounting plate 20 away from each other. The adjusting member 50 is arranged between the base 10 and the mounting plate 20, and the adjusting member 50 and the elastic member 40 cooperate to adjust the inclination angle of the mounting plate 20 relative to the base 10. The platform fixing frame 02 is arranged on the mounting plate 20. The base 10, the mounting plate 20, the elastic member 40 and the adjusting member 50 cooperate with each other to form a leveling mechanism.

[0040] By applying the technical solution of the utility model, the inclination angle of the platform fixing frame 02 relative to the base 10 can be adjusted by adjusting the inclination angle of the mounting plate 20 relative to the base 10, thereby driving the adjustment of the inclination angle of the molding platform 03, so that the molding platform 03 remains parallel to the exposure plane of the three-dimensional printing device, thereby improving the molding accuracy and quality of 3D printing. An elastic member 40 is arranged between the mounting plate 20 and the base 10, and the elastic member 40 provides a force to move away from each other to the mounting plate 20 and the base 10, so that the elastic member 40 supports the mounting plate 20. The above arrangement can ensure that there is an adjustment gap between the mounting plate 20 and the base 10, and the adjustment gap allows the mounting plate 20 to be slightly moved or adjusted relative to the base 10 to achieve the purpose of leveling. When adjusting the inclination angle of the mounting plate 20 relative to the base 10, it can be adjusted by the adjustment member 50. In the traditional technical solution, a plurality of bolts are usually arranged between the mounting plate and the base. In the process of leveling, a plurality of bolts need to be screwed. Such arrangement may cause interference between the bolts, which affects the leveling result and is cumbersome to operate. Compared with the traditional technical solution, the elastic member 40 and the adjusting member 50 in this solution cooperate with each other, simplifying the steps of the leveling operation, realizing dynamic linkage adjustment, reducing the mutual interference between the adjusting member 50 and the elastic member 40 during the adjustment process, and in addition, the elastic member 40 can absorb shock and vibration during the leveling process, reducing the possibility of collision between the mounting plate 20 and the base 10, and reducing structural damage caused by improper operation.

[0041] like Figure 4 and Figure 5As shown, in the embodiment of the present scheme, the first end of the adjusting member 50 is threadedly connected to the base 10 after passing through the mounting plate 20, and the second end of the adjusting member 50 is in contact with the side of the mounting plate 20 away from the base 10, and the adjusting member 50 can be movably arranged relative to the mounting plate 20. Specifically, the adjusting member 50 includes an adjusting bolt. With such an arrangement, its structure is simple, and the user can adjust the tilt angle by simply rotating the adjusting bolt, which reduces the difficulty of operation, and can achieve precise control of the tilt angle of the mounting plate 20, meeting the requirements of high-precision leveling. The first end of the adjusting member 50 is threadedly connected to the base 10, and the second end is in contact with the side of the mounting plate 20 away from the base 10, respectively providing stable support points between the adjusting member 50 and the base 10 and between the adjusting member 50 and the mounting plate 20, so that the mounting plate 20 is more stable during the leveling process.

[0042] Furthermore, the elastic member 40 is sleeved on the outer periphery of the adjusting member 50. In this way, the elastic member 40 and the adjusting member 50 can be integrated together, thereby improving the compactness of the structure. In addition, during the expansion and contraction of the elastic member 40, the adjusting member 50 can guide and limit the elastic member 40, thereby further improving the stability of the process of adjusting the inclination angle of the mounting plate 20.

[0043] Specifically, a first mounting groove 201 is provided on one side of the mounting plate 20 close to the base 10, and the first end of the elastic member 40 is inserted into the first mounting groove 201. A second mounting groove 101 is provided on one side of the base 10 close to the mounting plate 20, and the second end of the elastic member 40 is inserted into the second mounting groove 101. With such a configuration, the elastic member 40 can be installed in a hidden manner, making the overall structure more compact and facilitating the replacement of the elastic member 40. In addition, the first mounting groove 201 plays a guiding and limiting role in the expansion and contraction process of the elastic member 40, thereby improving the stability of the elastic member 40 during the compression and extension process.

[0044] This solution does not limit the specific form of the elastic member 40. The elastic member 40 can be configured as an elastic washer, a spring, or other elastic member.

[0045] In the embodiment of the present solution, the elastic member 40 comprises a rectangular spring. Such an arrangement enables the elastic member 40 to provide a larger load capacity in a smaller space and has good stability.

[0046] like Figure 4 and Figure 5As shown, specifically, the mounting plate 20 is further provided with a first through hole 202 and a first countersunk hole 203 which are connected in a stepped manner. The first through hole 202 is connected with the first mounting groove 201. The cross-sectional area of ​​the first through hole 202 is smaller than the cross-sectional area of ​​the first countersunk hole 203. The adjusting member 50 passes through the first through hole 202. There is a first gap between the adjusting member 50 and the first through hole 202. The second end of the adjusting member 50 is located in the first countersunk hole 203. In the embodiment of the present scheme, the nut of the adjusting bolt abuts against the bottom wall of the first countersunk hole 203. The provision of the first countersunk hole 203 can provide a holding space for the second end of the adjusting member 50, thereby preventing the adjusting member 50 from protruding outward from the mounting plate 20, and preventing the possibility that the mounting plate 20 may tilt relative to the base 10 due to the staff accidentally touching the adjusting member 50 after the leveling is completed.

[0047] Furthermore, the platform assembly further includes a blocking member 60, which is disposed at the opening of the first countersunk hole 203 and is used to block the opening of the first countersunk hole 203. This arrangement can avoid the possibility of resin flowing into the first countersunk hole 203 during the 3D printing operation, thereby ensuring the smoothness of the screwing process of the adjusting member 50.

[0048] The present solution does not limit the specific form of the blocking member 60 .

[0049] In the embodiment of the present solution, the blocking member 60 comprises a silicone plug. With such a configuration, the structure is simple and the installation and removal of the blocking member 60 can be easily realized.

[0050] In other embodiments of the present solution, the blocking member 60 may be provided in other forms such as a sealing cover.

[0051] Furthermore, a second mounting groove 101 is provided on the base 10, and a first threaded hole 102 is also provided on the base 10. The first threaded hole 102 is provided at the bottom of the second mounting groove 101, and the first end of the adjusting member 50 is threadedly connected with the first threaded hole 102. The provision of the second mounting groove 101 plays a role of limiting and guiding the expansion and contraction process of the elastic member 40, further improving the smoothness and stability of the expansion and contraction process of the elastic member 40.

[0052] That is, in the embodiment of the present scheme, the screw rod of the adjusting bolt passes through the first countersunk hole 203, the first through hole 202, the first mounting groove 201, and the second mounting groove 101 in sequence and is threadedly connected with the first threaded hole 102. The nut of the adjusting bolt is located in the first countersunk hole 203 and abuts against the bottom of the first countersunk hole 203.

[0053] like Figure 5 and Figure 6As shown, the platform assembly further includes a limiter 70, which is disposed between the base 10 and the mounting plate 20, and is used to limit the moving distance of the mounting plate 20 relative to the base 10. The setting of the limiter 70 can prevent the mounting plate 20 from excessively moving due to operational errors, and prevent the mounting plate 20 from moving too far relative to the base 10, further simplifying the operating process.

[0054] In the embodiment of the present solution, the stopper 70 includes a first section 71 and a second section 72 which are connected in a stepwise manner along the axial direction. The cross-sectional area of ​​the first section 71 is smaller than the cross-sectional area of ​​the second section 72. The first section 71 passes through the base 10 and is fixedly connected to the mounting plate 20. The first section 71 can move relative to the base 10, and the second section 72 is used to cooperate with a stopper on one side of the base 10 away from the mounting plate 20. When the mounting plate 20 is adjusted in a direction away from the base 10, the movement of the mounting plate 20 drives the stopper 70 to move. When the adjustment range of the mounting plate 20 is too large, the second section 72 of the stopper 70 cooperates with a stopper on one side of the base 10 away from the mounting plate 20. With such a configuration, the structure is simple, and it is convenient for the staff to know whether the mounting plate 20 is over-adjusted in time, and the stopper 70 can also play the role of connecting the base 10 and the mounting plate 20.

[0055] This solution does not limit the connection method between the first section 71 of the limiting member 70 and the mounting plate 20. The connection can be made by snap connection or other methods.

[0056] In the embodiment of the present solution, the first section 71 of the stopper 70 is threadedly connected to the mounting plate 20. Specifically, a second threaded hole 204 is provided on the end surface of the mounting plate 20 close to the base 10, and a second through hole 103 and a second countersunk hole 104 connected in a stepped manner are provided on the base 10. The second through hole 103 extends to the end surface of the base 10 close to the mounting plate 20, and the second countersunk hole 104 extends to the end surface of the base 10 away from the mounting plate 20, and the cross-sectional area of ​​the second countersunk hole 104 is greater than the cross-sectional area of ​​the second through hole 103.

[0057] Specifically, the limit member 70 includes a limit screw, the screw rod of the limit screw forms a first section, the diameter of the second through hole 103 is larger than the diameter of the screw rod of the limit screw, the nut of the limit screw forms a second section, there is a gap between the nut of the limit screw and the bottom of the second countersunk hole 104, and the nut of the limit screw is used to cooperate with the bottom stopper of the second countersunk hole 104.

[0058] Furthermore, the platform assembly also includes a connector 30 disposed between the base 10 and the mounting plate 20, and the base 10 and the mounting plate 20 are connected via the connector 30. The connector 30 includes a connecting screw, the screw rod of the connecting screw penetrates the base 10 and is threadedly connected to the mounting plate 20, and the nut of the connecting screw abuts against a side of the base 10 away from the mounting plate 20. Such a configuration has a simple structure and facilitates the connection between the mounting plate 20 and the base 10.

[0059] In the embodiment of this solution, a third threaded hole 205 is provided at one end of the mounting plate 20 close to the base 10, and a third through hole 105 and a third countersunk hole 106 are provided on the base 10 in a stepped manner, the third through hole 105 extends to the end surface of the base 10 close to the mounting plate 20, and the third countersunk hole 106 extends to the end surface of the base 10 away from the mounting plate 20, and the cross-sectional area of ​​the third countersunk hole 106 is larger than the cross-sectional area of ​​the third through hole 105. The screw of the connecting screw passes through the third countersunk hole 106 and the third through hole 105 in sequence and is threadedly connected with the third threaded hole 205.

[0060] Furthermore, the cross-sectional area of ​​the third through hole 105 is larger than the cross-sectional area of ​​the screw rod of the connecting screw, and the nut of the connecting screw abuts against the bottom of the third countersunk hole 106. A step structure is provided on the circumferential surface of the screw rod of the connecting screw, and the step structure abuts against the end surface of the end of the mounting plate 20 close to the base 10. Such a configuration can keep the relative position between the connecting screw and the mounting plate 20 stable, and can also keep the relative position between the connecting screw and the base 10 stable, so as to provide a reference for adjusting the inclination angle of the mounting plate 20.

[0061] This solution does not limit the specific forms of the base 10 and the mounting plate 20.

[0062] like Figure 7 As shown, in this embodiment, the base 10 includes a bottom plate 11, a first side plate 12 and a second side plate 13. The first side plate 12 and the second side plate 13 are arranged opposite to each other, and the bottom ends of the first side plate 12 and the second side plate 13 are respectively connected to the bottom plate 11.

[0063] The mounting plate 20 is arranged on a side of the two first side plates 12 and the second side plate 13 away from the bottom plate 11. The mounting plate 20 includes a top plate 21, a third side plate 22 and a fourth side plate 23. The third side plate 22 and the fourth side plate 23 are arranged opposite to each other, and the top ends of the third side plate 22 and the fourth side plate 23 are respectively connected to the top plate 21. The third side plate 22 and the first side plate 12 are arranged opposite to each other, and the fourth side plate 23 and the second side plate 13 are arranged opposite to each other, so that the top plate 21 and the bottom plate 11 are opposite to each other. The base 10 and the mounting plate 20 cooperate to form a mounting cavity, and the mounting cavity is used to install the weighing sensor 01 of the three-dimensional printing device. Specifically, during assembly, the weighing sensor 01 is detachably arranged on the bottom plate 11 and is located in the mounting cavity.

[0064] This solution does not limit the number and location of the connecting members 30 and the adjusting members 50 .

[0065] like Figures 3 to 7 As shown, in the embodiment of the present solution, one connecting member 30 is provided, the connecting member 30 is provided between the first side plate 12 and the third side plate 22 , and the connecting member 30 is provided at the middle position in the length direction of the first side plate 12 .

[0066] The adjusting member 50 is disposed between the second side plate 13 and the fourth side plate 23 . Two adjusting members 50 are provided. The two adjusting members 50 are spaced apart along the length direction of the second side plate 13 and are respectively close to two ends of the second side plate 13 .

[0067] One limiting member 70 is provided, and the limiting member 70 is disposed between the second side plate 13 and the fourth side plate 23 , and is located at a middle position in the length direction of the second side plate 13 .

[0068] There are four elastic members 40, two of which are respectively sleeved on the outer circumferences of the two adjusting members 50; the other two elastic members 40 are arranged between the first side plate 12 and the third side plate 22, and the two elastic members 40 are respectively arranged at the two ends in the length direction of the first side plate 12. The above arrangement has a reasonable structural layout, and the inclination angle of the mounting plate 20 relative to the base 10 can be adjusted by the two adjusting members 50, and the operation is more convenient.

[0069] In some embodiments of the present solution, a fixing member is further included. After the position of the mounting plate 20 relative to the base 10 is adjusted, the mounting plate 20 and the base 10 are fixed by the fixing member so that the mounting plate 20 and the base 10 are in a relatively fixed position. This arrangement enables the mounting plate 20 and the base 10 to remain stable after being adjusted to a suitable position, and avoids positional displacement caused by vibration or other external forces.

[0070] like Figure 1 and Figure 2As shown, specifically, the platform fixing frame 02 is a cubic shell structure, and both ends of the platform fixing frame 02 are open structures, specifically including a first plate body 021 and a second plate body 022 arranged opposite to each other, and a third plate body 023 and a fourth plate body 024 arranged opposite to each other. The end of the fourth plate body 024 away from the third plate body 023 is connected to the molding platform 03.

[0071] The whole formed by the base 10 and the mounting plate 20 is inserted into the platform fixing frame 02, and the mounting plate 20 is fixedly connected to the third plate body 023. There is a gap between the outer side walls of the base 10 and the mounting plate 20 and the inner side wall of the platform fixing frame 02, so that the platform fixing frame 02 moves relative to the base 10 with the mounting plate 20.

[0072] This solution does not limit the connection method between the mounting plate 20 and the third plate body 023. The connection can be made by means of snap connection, plug connection or fasteners.

When the locking mechanism 04 is in the locking state, the third plate body 023 and the mounting plate 20 are locked and fixed; when the locking mechanism 04 is in the opening state, the third plate body 023 and the mounting plate 20 are separated.

[0074] The embodiment of the utility model further provides a three-dimensional printing device, which includes a platform driving mechanism and the above-mentioned platform assembly, and the platform driving mechanism is drivingly connected to the base 10 of the platform assembly.

[0075] like Figure 1 As shown, further, the three-dimensional printing device also includes a weighing sensor 01, one end of which is inserted into the installation cavity of the platform assembly, and the weighing sensor 01 is detachably connected to the bottom plate of the base 10 via fasteners.

Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0079] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0080] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only to facilitate the distinction between corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0081] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
