Description

Technical Field

[0001] This invention relates to the field of machining technology, and more specifically to a method for manufacturing panels. Background Technology

[0002] In the existing technology, due to the limitations of processing equipment and site, it is difficult to directly process large-area plate components. Therefore, it is sometimes necessary to first produce multiple small-area plate components, and then splice the multiple plate components together to form a larger-area panel assembly that meets the design requirements.

[0003] For example, such as Figure 1 As shown, when manufacturing a large plate-shaped component with curved sides C', it is generally first divided into multiple relatively smaller unit plates 10' according to the design drawings. For example, as Figure 1 As shown, a large plate-shaped component with curved sides C is divided into four relatively smaller unit plates 10', namely the first plate-shaped component D1, the second plate-shaped component D2, the third plate-shaped component D3, and the fourth plate-shaped component D4; then the first plate-shaped component D1, the second plate-shaped component D2, the third plate-shaped component D3, and the fourth plate-shaped component D4 are manufactured separately; finally, the first plate-shaped component D1, the second plate-shaped component D2, the third plate-shaped component D3, and the fourth plate-shaped component D4 are spliced ​​together to form a larger panel assembly with curved sides C'.

[0004] Among them, the curved side units C0' of the first plate-shaped component D1, the second plate-shaped component D2, the third plate-shaped component D3, and the fourth plate-shaped component D4 are connected in sequence to form the curved side C' of the panel assembly.

[0005] Furthermore, the relatively small unit panels 10' mentioned above are manufactured using a direct cutting method. During the subsequent assembly process, to ensure that the curved side C formed by connecting the curved side units C0' of each unit panel 10' meets the design camber requirements when multiple unit panels 10' are assembled into the entire assembly, multiple adjustments are required at each joint to ensure the coplanarity of adjacent unit panels 10'. It is also necessary to ensure the parallel alignment of the two straight side panels and the alignment and connection of the curved side units C0' of adjacent unit panels 10'. However, since each joint consists of two straight side panels, it is impossible to find corresponding reference points or benchmarks, resulting in poor assembly accuracy, affecting product quality, and increasing the difficulty and production efficiency of the assembly process.

[0006] Therefore, when manufacturing panel assemblies with large areas and curved sides, how to reduce the difficulty of panel assembly, improve the accuracy of panel assembly, and improve the efficiency of panel assembly are technical problems that urgently need to be solved by those skilled in the art. Summary of the Invention

[0007] In view of this, the present invention provides a method for manufacturing panels that can reduce the difficulty of panel assembly, improve panel assembly accuracy, and increase panel assembly efficiency.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0009] A method for manufacturing a panel assembly, comprising splicing multiple unit panels to form a panel assembly with curved sides, including:

[0010] Prepare multiple unit boards, each of which has a first straight side and a second straight side that are parallel to each other. At least one side surface of each unit board is provided with multiple first straight holes and second straight holes. The multiple first straight holes are arranged sequentially and spaced apart along a preset trajectory of the curved side. One end of the second straight hole is located on the preset trajectory of the curved side, and the other end extends to the third side of the unit board.

[0011] Multiple unit boards are connected in sequence. During connection, for any two adjacent unit boards, the first perpendicular line of the first straight side of one unit board is adjusted to be collinear with the second perpendicular line of the second straight side of the other unit board, so that the straight sides of the adjacent unit boards are aligned head to head and tail to tail, and the curved sides of the adjacent unit boards are aligned and connected end to end along a preset trajectory.

[0012] Excess sheet metal is removed along the line connecting adjacent first straight holes to obtain the curved side of the panel assembly.

[0013] Optionally, the above manufacturing method further includes: polishing the curved side.

[0014] Optionally, in the above manufacturing method, when multiple unit plates are connected sequentially:

[0015] A straight line is obtained by connecting the midpoints of any two of the first straight-line sides, or any two of the second straight-line sides, or any midpoint of the first straight-line side and any midpoint of the second straight-line side.

[0016] Ensure that all first perpendicular bisectors and all second perpendicular bisectors are collinear with the stated line.

[0017] Optionally, in the above manufacturing method, the connecting line is provided with third through holes that are arranged sequentially and at intervals along a preset trajectory of the curved side.

[0018] Optionally, in the above manufacturing method, the end of the second straight hole away from the third side is located on the connecting line.

[0019] Optionally, in the above manufacturing method, the end of the second straight hole away from the third side extends to the first straight hole.

[0020] Optionally, in the above manufacturing method, a second straight hole is provided between each connecting line and the third side.

[0021] Optionally, in the above manufacturing method, the plurality of second straight holes are parallel to each other.

[0022] Optionally, in the above manufacturing method, the excess sheet material is nested.

[0023] Optionally, in the above manufacturing method, the third side is a straight side, a broken side, or an arc-shaped side.

[0024] Compared with existing technologies, the beneficial effects of this invention are as follows: In the panel manufacturing method provided by this invention, the splicing accuracy can be improved by aligning and overlapping the vertical lines of the straight sides of each unit panel. This includes improvements in point-to-point alignment accuracy and coplanar accuracy between adjacent unit panels, especially the alignment accuracy of the endpoints of the preset trajectories of the curved sides at the connection points and the relative positional deviation. Tests have shown that in the panel assembly product manufactured by this method, the center deviation accuracy of each unit panel can be controlled within 1mm, and the positioning accuracy of the final panel assembly product can be improved to within 0.5mm. Furthermore, it effectively reduces the difficulty of panel assembly, shortens assembly time, and improves assembly efficiency. Attached Figure Description

[0032] This invention provides a method for manufacturing panels, which reduces the difficulty of panel assembly, improves the accuracy of panel assembly, and increases the efficiency of panel assembly by aligning and splicing the panels along the vertical line and then cutting off the excess material.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This invention provides a method for manufacturing panel structures, particularly suitable for processing and manufacturing panel structures with non-linear sides (i.e., curved sides). Please refer to... Figure 2 and Figure 3 The panel manufacturing method includes the following steps S1, S2 and S3.

[0035] Step S1: Prepare multiple unit boards 10. Each unit board 10 is provided with a first straight side L1 and a second straight side L2 that are parallel to each other. At least one side surface of each unit board 10 is provided with multiple first straight holes 11 and second straight holes 13. The multiple first straight holes 11 are arranged sequentially and spaced apart along the preset trajectory C0 of the curved side (i.e., the design shape of the curved side of the finished panel). The two ends of the preset trajectory C0 of the curved side intersect with the first straight side L1 and the second straight side L2, respectively. One end of the second straight hole 13 is located on the preset trajectory C0 of the curved side, and the other end extends to the third side L3 of the unit board 10. The two ends of the third side L3 are connected to the first straight side L1 and the second straight side L2, respectively.

[0036] Step S2: Multiple unit plates 10 are connected sequentially. During connection, for any two adjacent unit plates 10, the first perpendicular line L1 of the first straight side L1 of one unit plate 10 is adjusted. 01 The second perpendicular line L of the second straight side L2 of another unit plate 10 02The collinearity allows the straight sides of two adjacent unit plates 10 to be aligned (i.e., the first straight side L1 of one unit plate 10 and the second straight side L2 of another unit plate 10 are aligned head-to-head and tail-to-tail). At the same time, the preset tracks C0 of the curved sides of two adjacent unit plates 10 are aligned head-to-tail and connected. Finally, the preset tracks C0 of the curved sides of multiple unit plates 10 are connected in sequence to form the pre-cut tracks C of the curved sides of the panel assembly.

[0037] For example, see Figure 2 The horizontal center lines of the first unit plate 101 and the second unit plate 102 are aligned and overlap to form L0. The horizontal center lines of the second unit plate 102 and the third unit plate 103 are aligned and overlap to form L0. The horizontal center lines of the third unit plate 103 and the fourth unit plate 104 are aligned and overlap to form L0. Thus, the horizontal perpendicular bisectors of the first unit plate 101, the second unit plate 102, the third unit plate 103, and the fourth unit plate 104 are aligned and collinear to form a straight line L.

[0038] Step S3: Remove excess sheet material along the line 12 connecting adjacent first straight holes 11 to obtain the curved side of the panel assembly.

[0039] As can be seen, in the panel manufacturing method provided by this invention, the splicing accuracy can be improved by aligning and overlapping the vertical lines of the straight sides of each unit panel 10. This includes improvements in point-to-point alignment accuracy and coplanarity accuracy of adjacent unit panels 10, especially the alignment accuracy of the endpoints of the preset trajectory C0 of the curved sides at the connection point and the relative positional deflection. Tests have shown that in the panel assembly product manufactured by this method, the center deviation accuracy of each unit panel 10 can be controlled within 1mm, and the positioning accuracy of the final panel assembly product can be improved to within 0.5mm. Furthermore, this method effectively reduces the difficulty of panel assembly, shortens assembly time, and improves assembly efficiency.

[0040] Furthermore, the panel manufacturing method provided by the present invention also includes step S4: grinding the curved side of the panel assembly to make it closer to the preset trajectory C0 of the curved side, thereby obtaining a curved side with shape trajectory and dimensional accuracy that better meets the design requirements.

[0041] In some embodiments, in step S2 above, when multiple unit plates 10 are connected sequentially, the midpoints of any two first straight-line sides L1, or the midpoints of any two second straight-line sides L2, or the midpoint of any one first straight-line side L1 and the midpoint of any one second straight-line side L2 can be connected first to obtain a straight line L (preferably connecting the midpoints A and B of the two straight-line sides located at the two ends, see details). Figure 2 Then adjust and ensure all first perpendicular lines L 01 and all second perpendicular lines L02 All are collinear with the straight line L. This ensures that the perpendicular bisectors of all unit plates 10 are aligned and collinear, so that the preset trajectories C0 of the curved sides of adjacent unit plates 10 are aligned and connected. The preset trajectories C0 of the curved sides of multiple unit plates 10 are connected in sequence to form the curved side trajectory of the panel assembly, ensuring the connection accuracy of the entire curved side, and ultimately achieving the replacement of arch with straight lines.

[0042] Specifically, please see Figure 4 In some embodiments, step S2 above includes:

[0043] Step S21: Multiple unit boards 10 are connected sequentially at the straight side (only the position is adjusted for alignment, and the connection does not have to be fixed).

[0044] Step S222: Select any two straight side edges (preferably the two straight side edges at the two ends) and connect the perpendicular bisectors to obtain a straight line L. Adjust all perpendicular bisectors to align with the straight line L so that the perpendicular bisectors of the straight side edges of adjacent unit plates 10 are collinear and overlap, thereby aligning and connecting the endpoints of the preset trajectory C0 of the curved side edges of adjacent unit plates 10.

[0045] Step S23: Multiple unit plates 10 are fixedly connected at the straight side to obtain a panel assembly with cutting residue (located outside the preset trajectory C0 on the curved side).

[0046] In comparison, Figure 1 During the splicing and assembly of multiple unit panels 10', even if the straight sides of each unit panel 10' are aligned by the vertical line, the vertical lines at each splicing point are not on the same straight line, so the accuracy is difficult to control.

[0047] Alternatively, please see Figure 5 In other embodiments, step S2 above includes:

[0048] Step S21: Multiple unit boards 10 are connected sequentially at the straight side (only the position is adjusted for alignment, and the connection does not have to be fixed).

[0049] Step S22: Adjust the perpendicular bisectors of the straight sides of adjacent unit plates 10 to be collinear so that the endpoints of the preset trajectory C0 of the curved sides of adjacent unit plates 10 are aligned and connected.

[0050] Step S221: When verifying whether the perpendicular bisectors of the straight sides of adjacent unit plates 10 are collinear and aligned, a straight line can be obtained by connecting the perpendicular bisectors (or the midpoints) of any two straight sides (preferably the two straight sides at the two ends). Verify whether all perpendicular bisectors are aligned with this straight line: if yes, it proves that all unit plates 10 are aligned; if no, adjust the position of adjacent unit plates 10 according to whether the preset trajectory C0 of the curved sides in adjacent unit plates 10 is aligned and connected.

[0051] Step S23: Multiple unit plates 10 are fixedly connected at the straight side to obtain a panel assembly with cutting residue (i.e. located outside the preset trajectory C0 on the curved side).

[0052] In specific implementation, the first straight hole 11 can be made by cutting. The connecting line 12 refers to a connecting line obtained by straightly connecting the uncut portions between adjacent first straight holes 11, or it can be a connecting line mark pre-made according to a preset trajectory C0 of a curved side. For example, in some embodiments, by providing multiple third through holes arranged sequentially and at intervals along a preset trajectory C0 of a curved side between adjacent first straight holes 11, the connecting line of the multiple third through holes and its connection line with the ends of the first straight holes 11 on both sides constitute the connecting line 12. This connecting line 12... Figure 2 , Figure 6 and Figure 7 All are represented by dashed lines. In some embodiments, the length of the connecting line 12 ranges from 50mm to 100mm.

[0053] Please see Figure 2 In some embodiments, the end of the second straight hole 13 away from the third side L3 can be located on the connecting line 12, that is, the second straight hole 13 intersects the connecting line 12 but does not pass through the connecting line 12. Thus, the connecting line 12 on both sides of the first straight hole 11 is cut along the preset trajectory C0 of the curved side until it intersects with the second straight hole 13, and the excess sheet material can be removed.

[0054] Alternatively, in other embodiments, the end of the second straight hole 13 away from the third side L3 of the unit plate 10 can extend to the first straight hole 11 (not shown in the figure), that is, the second straight hole 13 intersects with the first straight hole 11 but does not pass through the first straight hole 11. Thus, by cutting along the connecting line 12 to the first straight hole 11, the excess board material can be removed.

[0055] Preferably, in some embodiments, a second straight hole 13 is provided between each connecting line 12 and the third side L3. Moreover, the plurality of second straight holes 13 are parallel to each other.

[0056] To further optimize the above technical solution, in the above panel manufacturing method, excess sheet material can also be nested to produce other parts, thereby improving material utilization. In specific implementation, when creating the curved side preset trajectory C0 on the unit plate 10, nesting marks can also be made in the area of ​​excess sheet material; or, the excess sheet material can be reused by nesting or other methods after being cut off.

[0057] In practice, each unit plate 10 can be a web or other plate-shaped component from any other field. Adjacent unit plates 10 can be fixedly connected by riveting or welding, or they can be fixedly connected by fastening with connecting accessories or other methods as needed.

[0058] In practice, the outer contour of each unit panel 10 does not necessarily need to be perfectly square. It only needs to have two parallel and aligned straight sides: a first straight side L1 and a second straight side L2. These straight sides allow multiple unit panels 10 to be sequentially joined together, and the perpendicular bisectors of the first straight side L1 and the second straight side L2 of the joined unit panels 10 must be collinear. Generally, the first straight side L1 and the second straight side L2 need to have a certain length (e.g., 200mm) to facilitate later panel alignment. In other words, the third side L3 of each unit panel 10 can be a straight side (e.g., ...). Figure 3 (as shown), or it can be a polygonal side (such as...) Figure 6 (as shown in the image), or it could be a curved side (such as...). Figure 7 As shown in the figure, or other sides of any shape, as long as they do not affect the implementation of the above panel manufacturing method, the present invention does not specifically limit the specific shape of the third side L3 of the unit panel 10.

[0059] In practice, when manufacturing the panel assembly, it can be made by continuously assembling two, three, four, or five unit panels 10, or by continuously assembling more unit panels 10. It should be noted that... Figure 3 , Figure 6 and Figure 7 The present invention uses only four unit plates 10 continuously spliced ​​together to form a panel assembly as an example for demonstration purposes. The present invention does not specifically limit the number of panel components.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed.
