[0047] In order to better understand the purpose, structure, features and effects of the present invention, the present invention is further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that the features shown in the drawings are not necessarily drawn to scale. In addition, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments.

The words "first", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Up", "down", "left", "right", "front", "back" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly. In addition, in the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a seedling raising tray, which includes a main body 1 and a plurality of components 4 assembled to the main body 1 .

[0050] like Figure 4 , Figure 5 and Figure 6 As shown, the body 1 is divided into a plurality of separated components 11 by a transverse dividing line 2 and a longitudinal dividing line 3. According to the outer dimensions of the body 1, the intervals and numbers of the transverse dividing lines 2 and the longitudinal dividing lines 3 can be selected to ensure that each component 11 is small enough to be normally printed by an ordinary small-sized 3D printer. In this embodiment, there are two transverse dividing lines 2 and two longitudinal dividing lines 3, respectively, so that the body 1 is divided into 9 components 11. These components 11 have equal transverse dimensions and equal longitudinal dimensions, which can have many advantages. For example, as long as the size of one of the components 11 is suitable for printing by the printer, all other components 11 are definitely suitable for printing by the printer. In addition, this can sometimes make some components 11 interchangeable. For example, in this embodiment, the four components 11 located at the upper left, upper right, lower left, and lower right corners are substantially the same, and the four components 11 located at the middle left, middle right, upper middle, and lower middle are substantially the same, but have different assembly angles.

[0051] The body 1 has a plurality of assembly grooves 12 formed by being recessed downward from its top surface, and the assembly grooves 12 are respectively distributed along the transverse dividing line 2 and the longitudinal dividing line 3. The transverse dividing line 2 directly penetrates from one transverse end face of the body 1 to another transverse end face, and the longitudinal dividing line 3 directly penetrates from one longitudinal end face of the body 1 to another longitudinal end face. Some of the assembly grooves 12 are only penetrated by the transverse dividing line 2, some of the assembly grooves 12 are only penetrated by the longitudinal dividing line 3, and some of the assembly grooves 12 are simultaneously penetrated by the transverse dividing line 2 and the longitudinal dividing line 3. As required, the sizes of different assembly grooves 12 may be different. In this embodiment, the transverse dividing line 2 and / or the longitudinal dividing line 3 just pass through the middle of the assembly groove 12. The assembly grooves 12 and the dividing lines are arranged in this way, so that each component 11 has a part of the structure of the assembly groove 12 located in different directions, for example, a component 11 located in the upper left corner has a half structure of three assembly grooves 12 located in different directions, and a component 11 located in the left corner has a half structure of four assembly grooves 12 located in different directions, so that it is possible for the component 11 to be locked due to the interlocking effect.

[0052] like Figure 1 , Figure 3 and Figure 7 As shown, the plurality of components 4 are respectively matched with the plurality of assembly grooves 12. When the plurality of components 4 are respectively installed in the plurality of assembly grooves 12, an interlocking effect is generated between the component 11 and the component 4, so that each component 11 is locked. For example, when the component 11 is to be pulled outward in all directions, the component 11 cannot be pulled because of the obstruction of other components 11 and the component 4, so that the component 4 and the component 11 become a firm and inseparable whole after being assembled.

[0053] like Figure 2 As shown, in order to make the assembly 4 and the body 1 coordinated and unified, when the assembly 4 is installed in the assembly groove 12, the top surface of the body 1 is flush with the top surface of the assembly 4. In addition, at this time, a part of the horizontal dividing line 2 and the vertical dividing line 3 will be blocked by the assembly 4 and not displayed, thereby shielding the local horizontal dividing line 2 and the vertical dividing line 3.

[0054] The body 1 has a plurality of first seedling raising holes 13 formed by being recessed downward from its top surface, and the assembly 4 has a plurality of second seedling raising holes 41 formed by being recessed downward from its top surface. When the assembly 4 is respectively installed in the assembly groove 12, the second seedling raising holes 41 correspond to the arrangement of the first seedling raising holes 13, so that the assembly 4 and the body 1 can be coordinated and unified to form a complete seedling tray. In order not to destroy the structure of the first seedling raising holes 13, the transverse dividing line 2 and the longitudinal dividing line 3 of the body 1 just avoid the first seedling raising holes 13.

[0055] In the process of separating the seedling tray, in order to fully consider the assembly problems caused by the printer error, an active error compensation method can be adopted to leave a predetermined matching gap between the component 4 and the assembly groove 12 for easy assembly. In this embodiment, a 1 mm gap is reserved between the contact part of the component 4 and the assembly groove 12.

[0056] In order to further strengthen the firmness of the assembled whole, the component 4 is glued to the assembly groove 12 of the body 1 by glue. In addition, the bottom surface of the assembly groove 12 is provided with a first vertical threaded hole 14, and the component 4 is provided with a second vertical threaded hole 42 corresponding to the first vertical threaded hole 14. The fastener cooperates with the first vertical threaded hole 14 and the second vertical threaded hole 42 to fix the component 4 to the body 1. In the assembly of each component, not only glue is used for bonding, but also fasteners are used for fixing, which will make the seedling tray more stable, and the joint between the component 4 and the body 1 is concealed, which does not affect the overall effect and performance of the seedling tray.

[0057] Based on the above-mentioned seedling raising tray, the present invention also provides a method for dividing the interlocking components of the seedling raising tray, wherein the body 1 is divided into a plurality of separate components 11 by a transverse dividing line 2 and a longitudinal dividing line 3, and the body 1 has a plurality of assembly grooves 12 formed by being recessed downward from its top surface, and the assembly grooves 12 are respectively distributed along the transverse dividing line 2 and the longitudinal dividing line 3 and the assembly grooves 12 are passed through by the transverse dividing line 2 and / or the longitudinal dividing line 3, so that each component 11 has a part of the structure of a different assembly groove 12, and a plurality of components 4 are provided, which cooperate with the plurality of assembly grooves 12 respectively. Among them, when the plurality of components 4 are respectively loaded into the plurality of assembly grooves 12, an interlocking effect is generated between the components 11 and the components 4, so that each component 11 is locked. The seedling raising tray is divided by such a dividing method so that it can be printed by an ordinary small-sized 3D printer.

[0058] Based on the above-mentioned seedling raising tray and segmentation method, the present invention also provides a 3D printing method for the seedling raising tray, wherein the above-mentioned multiple components 11 and multiple assemblies 4 are printed by a 3D printer, and then the multiple components 11 and multiple assemblies 4 are assembled into a seedling raising tray.

[0059] In order to solve the technical problem of printing large-sized seedling trays by ordinary small-sized 3D printers, the present invention chooses to split and divide the large-sized seedling trays. In the printing process of the seedling tray, it is necessary to consider the gravity and external load that the seedling tray can withstand after assembly, and at the same time, the overall structure of the seedling tray cannot be affected. Therefore, the splitting method of the seedling tray is extremely important. In order to meet the strength requirements of the seedling tray assembly, the present invention provides an interlocking component splitting method and a pot-cultivated seedling tray and a 3D printing method based on the interlocking component splitting method, which is a method for solving the problem that the printed plane size is much larger than the thickness size and the assembled product has a certain vertical stress. After the component 4 is assembled to the body 1, for the seedling tray as a whole, a part of the splitting line is a penetration splitting (i.e., there is no position of the component 4), and a part of the splitting line is a staggered stacked semi-transparent splitting (i.e., for the position where the component 4 is located, the bottom of the component 4, i.e., the bottom layer of the seedling tray, is split, and the component 4 itself is not split), so that the component 4 and the component 11 have a certain degree of interlayer staggered interlocking assembly function.

[0060] The above detailed description is only an explanation of the preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the description and illustrations of this creation are included in the patent scope of this creation.
