For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0041] The present application embodiment provides a method for preparing a prism, please refer to Figure 1 ,include:
[0042] S100: providing a first substrate and a second substrate, and fixing surfaces of the first substrate and the second substrate together to obtain a first composite substrate.
[0043] Please refer to Figure 2 The surfaces of the first substrate 10 and the second substrate 20 are parallel to each other, and the direction in which the first substrate 10 and the second substrate 20 are sequentially stacked is perpendicular to the surface of the first substrate 10. The surfaces of the first substrate 10 and the second substrate 20 are fixed together to form a first composite matrix 100.
[0044] It should be noted that the surfaces of the first substrate 10 and the second substrate 20 can be directly attached and fixed together, or can be indirectly fixed together through other sheet structures, as long as the first substrate 10 and the second substrate 20 can be relatively fixed.
[0045] Since the first composite matrix 100 needs to be processed into a plurality of composite sub-matrices 110 in the shape of rectangular parallelepiped in the subsequent process, preferably, the first substrate 10 and the second substrate 20 are both rectangular and of equal size. In this way, the first composite matrix 100 in the shape of rectangular parallelepiped can be directly formed, and then the first composite matrix 100 in the shape of rectangular parallelepiped can be processed into a plurality of composite sub-matrices 110 in the shape of rectangular parallelepiped, which can reduce the waste of materials.
[0046] S200: cutting the first composite substrate to obtain a plurality of composite sub-substrates, wherein the composite sub-substrates are in the shape of rectangular parallelepipeds and include a first sub-substrate and a second sub-substrate.
[0047] Please refer to Figure 3 , the first composite matrix 100 is cut along a direction parallel to the sequential stacking direction of the first substrate 10 and the second substrate 20, and the first composite matrix 100 is processed into a plurality of composite sub-matrices 110 in the shape of rectangular parallelepipeds. For example, the first composite matrix 100 is cut into a plurality of composite sub-matrices 110 by a wire cutting process. Preferably, the sizes of the plurality of composite sub-matrices 110 are equal to improve the utilization rate of the material.
[0048] Each composite sub-substrate 110 includes a first sub-substrate 11 and a second sub-substrate 21 , wherein the first sub-substrate 11 is a part of the first substrate 10 , and the second sub-substrate 21 is a part of the second substrate 20 .
[0049] S300: tilting a plurality of composite sub-matrices at a preset angle, and sequentially attaching and fixing composite surfaces of the plurality of composite sub-matrices together along a preset direction to obtain a second composite matrix.
[0050] Please refer to Figure 4 After the multiple composite sub-matrices 110 are tilted at the same angle, they are sequentially bonded and fixed together along a preset direction A to obtain a second composite matrix 200. The angle between the preset direction A and the composite surface 111 of the composite sub-matrix 110 is greater than 0° and less than 90°, preferably between 30° and 60°.
[0051] It should be noted that in order to be able to smoothly cut the prism 400 from the second composite substrate 200 in the subsequent process, the orthographic projections of the multiple first sub-substrates 11 on the multiple composite sub-substrates 110 along the preset direction A have overlapping areas, and the orthographic projections of the multiple second sub-substrates 21 on the multiple composite sub-substrates 110 along the preset direction A also have overlapping areas.
[0052] S400: removing material from the second composite matrix along a first processing plane and a second processing plane respectively to obtain a third composite matrix, wherein the first processing plane and the second processing plane are parallel to a preset direction respectively.
[0053] Please refer to Figure 5 , determine a first processing plane M1 and a second processing plane M2, the first processing plane M1 and the second processing plane M2 are respectively parallel to the preset direction A. The first processing plane M1 sequentially passes through the plurality of first sub-substrates 11, and can respectively cut out triangular prisms 400 in the shape of triangular prisms on the plurality of first sub-substrates 11. The second processing plane M2 sequentially passes through the plurality of second sub-substrates 21, and can respectively cut out triangular prisms 400 in the shape of triangular prisms on the plurality of second sub-substrates 21.
[0054] The plurality of first sub-substrates 11 are processed along the first processing plane M1, and part of the material of the first sub-substrates 11 is removed, so that the first sub-substrates 11 are changed into a triangular prism shape. The plurality of second sub-substrates 21 are processed along the second processing plane M2, and part of the material of the second sub-substrates 21 is removed, so that the plurality of second sub-substrates 21 are changed into a triangular prism shape.
[0055] For example, the edges of the plurality of first sub-substrates 11 distributed along the diagonal lines are all located in the first processing plane M1 , and the edges of the plurality of second sub-substrates 21 distributed along the diagonal lines are all located in the second processing plane M2 .
[0056] S500: Separating the first sub-substrate and the second sub-substrate in the shape of a triangular prism in the third composite substrate to obtain a plurality of triangular prisms.
[0057] Please refer to Figure 6 After the material removal process, the second composite substrate 200 becomes a third composite substrate 300, and the shapes of the first sub-substrate 11 and the second sub-substrate 21 in the third composite substrate 300 are both triangular prisms. By separating a plurality of first sub-substrates 11 and a plurality of second sub-substrates 21, a plurality of mutually independent first sub-substrates 11 and second sub-substrates 21 can be obtained at the same time, and the processing efficiency is high.
[0058] The above-mentioned method for preparing a prism can prepare a plurality of prisms 400 at the same time, and the processing efficiency is high. Figure 7 When the first substrate 10 and / or the second substrate 20 has a patterned surface, the patterned surface can be placed toward the other substrate, thereby protecting the patterned surface and avoiding damage to the patterned surface during processing. Therefore, the above-mentioned method for preparing a prism is also applicable to preparing a prism 400 having a pattern on the surface.
[0059] Optionally, see Figure 8 , the preparation method of the prism also includes:
[0060] S110: providing a first matching sheet, and sequentially stacking, laminating and fixing the first base sheet, the first matching sheet and the second base sheet together to obtain a first composite base.
[0061] Please refer to Figure 2 The surfaces of the first substrate 10, the first matching sheet 30 and the second substrate 20 are parallel to each other, and the direction in which the first substrate 10, the first matching sheet 30 and the second substrate 20 are stacked in sequence is perpendicular to the surface of the first substrate 10. The first matching sheet 30 is located between the first substrate 10 and the second substrate 20, and the two opposite surfaces of the first matching sheet 30 are respectively attached and fixed to the surface of the first substrate 10 and the surface of the second substrate 20 to form a first composite matrix 100.
[0062] Since the first composite matrix 100 needs to be processed into a plurality of composite sub-matrices 110 in the shape of rectangular parallelepiped in the subsequent process, preferably, the first substrate 10, the first matching sheet 30 and the second substrate 20 are all rectangular and of equal size. In this way, the first composite matrix 100 in the shape of rectangular parallelepiped can be directly formed, and then the first composite matrix 100 in the shape of rectangular parallelepiped can be processed into a plurality of composite sub-matrices 110 in the shape of rectangular parallelepiped, which can reduce the waste of materials.
[0063] The first composite substrate is cut to obtain a plurality of composite sub-substrates, wherein the composite sub-substrates are in the shape of a cuboid, and the composite sub-substrates include a first sub-substrate and a second sub-substrate.
[0064] S210: cutting the first composite substrate to obtain a plurality of composite sub-substrates, wherein the composite sub-substrates are in the shape of rectangular parallelepipeds and include a first sub-substrate, a first sub-substrate and a second sub-substrate.
[0065] Please refer to Figure 3 The first composite substrate 100 is cut along a direction parallel to the sequential stacking direction of the first substrate 10, the first matching sheet 30 and the second substrate 20, and the first composite substrate 100 is processed into a plurality of composite sub-substrates 110 in the shape of rectangular parallelepipeds. Each composite sub-substrate 110 includes a first sub-substrate 11, a first sub-matching sheet 31 and a second sub-substrate 21, wherein the first sub-substrate 11 is a part of the first substrate 10, the first sub-matching sheet 31 is a part of the first matching sheet 30, and the second sub-substrate 21 is a part of the second substrate 20.
[0066] By adding the first matching sheet 30 between the first substrate 10 and the second substrate 20, the size difference of the finally prepared prism 400 can be balanced. By adjusting the thickness of the matching sheet, the size of the produced prism 400 can also be adjusted.
[0067] Optionally, please refer to Figure 7 A surface of at least one of the first substrate 10 and the second substrate 20 includes a patterned surface, and the patterned surface faces the first matching sheet 30 .
[0068] When the first substrate 10 and the second substrate 20 are attached and fixed to the first matching sheet 30, the patterned surface is attached and fixed to the surface of the first matching sheet 30, and the first matching sheet 30 can protect the patterned surface. After the processing is completed, the pattern on the patterned surface can be retained on the prism 400, thereby obtaining a prism 400 with a pattern on the surface.

[0072] Please refer to Figure 4The second sheet 40 and the third sheet 50 are respectively placed on both sides of the plurality of composite sub-matrices 110, and after the second sheet 40, the plurality of composite sub-matrices 110 and the third sheet 50 are tilted at the same angle, they are sequentially attached and fixed together along the preset direction A, thereby obtaining the second composite matrix 200. The second sheet 40 can protect the second sub-substrate 21 in the composite sub-matrix 110 located at the edge, and the third sheet 50 can protect the first sub-substrate 11 in the composite sub-matrix 110 located at the edge.
[0073] Optionally, see Fig.10 , tilting a plurality of composite sub-matrices at a preset angle, and sequentially attaching and fixing the composite surfaces of the plurality of composite sub-matrices together along a preset direction to obtain a second composite matrix comprising:

[0075] S340: coating glue between the composite surfaces of two adjacent composite sub-matrices, and curing the glue to sequentially adhere and fix the multiple composite sub-matrices together to obtain a second composite matrix.
[0076] Please refer to Figure 4 The angle jig stacks and supports the multiple composite sub-matrices 110, so that the multiple composite sub-matrices 110 are tilted at a preset angle. Glue is applied between the composite surfaces 111 of two adjacent composite sub-matrices 110, and the two adjacent composite sub-matrices 110 are glued and fixed together by curing the glue, thereby obtaining a second composite matrix 200.
[0077] For example, the glue is a shadowless glue. After the shadowless glue is applied, an ultraviolet lamp is used to irradiate the shadowless glue to solidify it.
[0078] It should be noted that if a second patch 40 and a third patch 50 need to be set on both sides of multiple composite sub-matrices 110, the second patch 40 and the third patch 50 are also placed in the angle fixture, and glue needs to be coated between the second patch 40 and the composite sub-matrix 110 and between the third patch 50 and the composite sub-matrix 110, and the glue needs to be cured.

For example, the first substrate 10 and the second substrate 20 are fixed together by a gluing device.
[0082] It should be noted that if a first matching sheet 30 is further disposed between the first substrate 10 and the second substrate 20 , the surfaces of the first substrate 10 and the second substrate 20 are respectively glued and fixed to two opposite surfaces of the first matching sheet 30 .

[0086] Please refer to Figure 5 and Figure 6 After the first sub-substrate 11 and the second sub-substrate 21 are processed into a triangular prism shape, the third composite matrix 300 is debonded to remove the glue fixing the first sub-substrate 11 and the second sub-substrate 21, so that the plurality of first sub-substrates 11 and the plurality of second sub-substrates 21 become mutually independent individuals. The plurality of first sub-substrates 11 and the plurality of second sub-substrates 21 after debonding are the triangular prism 400. The triangular prism 400 is then cleaned to remove impurities such as residual glue on its surface.

The milling process has high processing efficiency and high precision, and can quickly remove excess material. Then, the third composite substrate 300 is ground to a desired size by a grinding process.
[0091] In one embodiment, the second composite substrate 200 is subjected to material removal along the first processing plane M1 by a milling process, and then the second composite substrate 200 is ground along the first processing plane M1 by a grinding process. After turning over, the second composite substrate 200 is subjected to material removal along the second processing plane M2 by a milling process again, and then the second composite substrate 200 is ground along the second processing plane M2 by a grinding process.
[0092] In another embodiment, the second composite substrate 200 is firstly removed from the material along the first processing plane M1 and the second processing plane M2 by a milling process, and then the second composite substrate 200 is ground along the first processing plane M1 and the second processing plane M2 by a grinding process, so as to grind the third composite substrate 300 to a second preset size.

For example, the surface shape and surface roughness value of the composite sub-matrix 110 are controlled within the specification requirements. Then, the ground composite sub-matrix 110 is cleaned to remove impurities on the surface of the composite sub-matrix 110.
