Description

Technical Field

[0001] This application relates to the field of sheet production, and in particular to a sheet folding device. Background Technology

[0002] As electronic devices rapidly develop towards miniaturization and high-density integration, sheet circuit boards (also known as flexible sheet FPCs, rigid-flex boards, etc.) are widely used in precision electronic products such as foldable screen phones, wearable devices, and micro sensors. To achieve complex layouts of sheet materials in a limited space, it is sometimes necessary to fold the sheet materials to form specific angles or stacked structures.

[0003] Existing folding devices generally include a folding seat, a vertical folding mechanism, and a horizontal folding mechanism. Both the vertical and horizontal folding mechanisms are located on the folding seat. The sheet material to be folded is placed on the folding seat. The vertical folding mechanism folds the part of the sheet material that needs to be folded in the vertical direction until the part of the sheet material that needs to be folded is perpendicular to the part of the sheet material that does not need to be folded. Then the horizontal folding mechanism pushes the sheet material to continue folding until the sheet material is folded into a specific angle or a stacked structure.

[0004] The aforementioned technologies involve alternating between vertical and horizontal folding mechanisms to fold the sheet material, making the folding process quite complex. Summary of the Invention

[0005] To make sheet folding simpler and more convenient, this application provides a sheet folding device.

[0006] The sheet folding device provided in this application adopts the following technical solution:

[0007] A sheet folding device includes a folding seat, a folding mechanism, and a pressing mechanism. The folding mechanism includes multiple folding frames, a folding platform, and multiple driving components. Each folding frame is rotatably mounted on the folding seat. The folding platform includes a main body and multiple folding parts. The main body is fixedly mounted on the folding seat, and each folding part is fixedly mounted on a folding frame. Each folding part abuts against the main body. The sheet to be folded is placed on the folding platform. Each driving component is mounted on the folding seat and is used to drive each folding frame. The pressing mechanism is mounted on the folding seat and is used to press the sheet.

[0008] By adopting the above technical solution, when the sheet material needs to be folded, the sheet material is placed on the folding table with the positions of the sheet material to be bent aligned with the main body and the connection points of the folding parts. Then, the pressing mechanism presses and fixes the sheet material, and the driving components drive the folding frames to rotate. This causes each folding frame to drive each folding part to rotate around the connection point between the folding part and the main body, thereby folding the sheet material located at each folding part towards the sheet material located near the main body until the sheet material is folded to a suitable angle. This completes the folding of the sheet material, forming a specific angle or layered structure. This makes sheet material folding simpler and more convenient, and improves the problem of the complex sheet material folding process caused by alternating between vertical and horizontal folding mechanisms.

[0009] Optionally, the drive assembly includes a drive motor, a main drive wheel, a driven wheel, and a drive belt. The drive motor is fixedly mounted on the folding seat, the main drive wheel is coaxially fixedly mounted on the drive motor, the driven wheel is coaxially fixedly mounted on the frame, and the drive belt is wound around the main drive wheel and the driven wheel.

[0010] Optionally, the pressing mechanism includes a pressing plate, which slides and engages with the folding seat. When the sheet is placed on the folding table, the pressing plate and the sheet are pressed and fixed together.

[0011] Optionally, the clamping plate is provided with multiple folding surfaces, each folding surface is respectively arranged facing each folding part, and each folding surface is inclined from top to bottom from the side away from each folding part to the side closer to each folding part.

[0012] Optionally, the clamping mechanism further includes a lifting assembly, which includes a lifting seat and a lifting cylinder. The lifting seat is detachably connected to the clamping plate, and the lifting cylinder is disposed on the folding seat. The piston rod of the lifting cylinder is fixedly connected to the lifting seat. When the lifting cylinder is driven, the lifting seat drives the clamping plate to move in the vertical direction.

[0013] Optionally, the clamping mechanism further includes a horizontal assembly, which includes a horizontal seat and a horizontal cylinder. The horizontal seat slides horizontally and engages with the folding seat. The horizontal seat is fixedly connected to the cylinder body of the lifting cylinder. The horizontal cylinder is fixedly mounted on the folding seat, and the piston rod of the horizontal cylinder is fixedly connected to the horizontal seat.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] When the sheet material needs to be folded, it is placed on the folding table with the points where it needs to be bent aligned with the main body and the connection points of the folding parts. The clamping mechanism then clamps and fixes the sheet material, and the drive components drive the folding frames to rotate. Each folding frame then drives the folding parts to rotate around the connection points between the folding parts and the main body, thus folding the sheet material at each folding part toward the sheet material near the main body until the sheet material is folded to the appropriate angle. This completes the folding of the sheet material, forming a specific angle or layered structure. This makes sheet folding simpler and more convenient, improving upon the problem of the complex sheet folding process caused by alternating between vertical and horizontal folding mechanisms.

[0025] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0026] This application discloses a sheet folding device. (Refer to...) Figure 1 A sheet folding device includes a folding seat 1, a folding mechanism 2, and a pressing mechanism 3, with the folding mechanism 2 and the pressing mechanism 3 both disposed on the folding seat 1.

[0027] Reference Figure 2 and Figure 3 The folding mechanism 2 includes two folding frames 21 and two drive components 22. Both folding frames 21 are rotatably mounted on the folding base 1 and are perpendicular to each other. The two drive components 22 are respectively connected to the two folding frames 21. The drive components 22 include a drive motor 221, a main drive wheel 222, a driven wheel 223, and a drive belt 224. The drive motor 221 is fixedly mounted on the folding base 1, the main drive wheel 222 is coaxially fixedly mounted on the drive motor 221, the driven wheel 223 is coaxially fixedly mounted on the frame, and the drive belt 224 is wound around the main drive wheel 222 and the driven wheel 223.

[0028] When the folding frame 21 rotates, the drive motor 221 drives it. The output shaft of the drive motor 221 drives the main drive wheel 222 to rotate. The main drive wheel 222 drives the driven wheel 223 to rotate through the drive belt 224. The rotation of the driven wheel 223 drives the folding frame 21 to rotate, thus completing the drive of the folding frame 21, making the drive of the folding frame 21 simpler and more convenient.

[0029] Reference Figure 4 and Figure 5 The folding mechanism 2 also includes a folding table 23, which includes a main body 231 and two folding parts 232. The main body 231 is perpendicular to the two folding parts 232 on both sides. The two folding parts 232 are rectangular and abut against the two sides of the main body 231 on both sides. The main body 231 is fixedly mounted on the folding seat 1, and the two folding parts 232 are fixedly mounted on the folding frame 21. The main body 231 and the two folding parts 232 on the side away from the folding seat 1 are all located on the same horizontal plane. When the sheet material to be folded is placed on the folding seat 1, the main body 231 of the sheet material is located on the main body 231, and the two parts of the sheet material to be folded are located on the two folding parts 232 respectively.

[0030] Reference Figure 6 The pressing mechanism 3 includes a horizontal component 31, which includes a horizontal seat 311 and a horizontal cylinder 312. The horizontal seat 311 slides horizontally and engages with the folding seat 1. In this embodiment, the sliding direction of the horizontal seat 311 is parallel to the diagonal of the rectangle formed by the two perpendicular sides of the main body 231. The horizontal cylinder 312 is fixedly mounted on the folding seat 1. The piston rod of the horizontal cylinder 312 is fixedly connected to the horizontal seat 311. When the horizontal cylinder 312 is driven, the piston rod of the horizontal cylinder 312 drives the horizontal seat 311 to slide horizontally toward or away from the two folding frames 21.

[0031] Reference Figure 7 The pressing mechanism 3 also includes a lifting assembly 32, which includes a lifting seat 321 and a lifting cylinder 322. The lifting seat 321 slides vertically and is fitted to the horizontal seat 311. The lifting cylinder 322 is fixedly mounted on the horizontal seat 311. The piston rod of the lifting cylinder 322 is fixedly connected to the lifting seat 321. When the lifting cylinder 322 is driven, the piston rod of the lifting cylinder 322 drives the lifting seat 321 to slide vertically toward or away from the folding seat 1.

[0032] Reference Figure 7 and Figure 8 The clamping mechanism 3 also includes a clamping plate 33, which is fixedly connected to the lifting seat 321 by bolts to achieve a detachable connection between the clamping plate 33 and the lifting seat 321. At the same time, when the horizontal component 31 is driven, the clamping plate 33 moves horizontally toward or away from the sheet material, so that when the clamping plate 33 does not need to clamp the sheet material, it moves away from the sheet material, thus making it less likely to affect the placement of the sheet material. When the lifting component 32 is driven, the clamping plate 33 moves vertically toward or away from the sheet material, thereby achieving clamping and fixing of sheet materials of various thicknesses.

[0033] Reference Figure 7 and Figure 8 The pressing plate 33 is provided with two folding surfaces 331. The two folding surfaces 331 correspond to and are directly opposite the two folding parts 232. The two folding surfaces 331 are inclined from top to bottom from the side away from the two folding parts 232 to the side closer to each folding part 232, so that when the folding mechanism 2 folds the sheet material to abut and cooperate with the folding surfaces 331, it completes the folding of the sheet material at the specific folding angle required.

[0034] The implementation principle of the sheet folding device in this application embodiment is as follows: When the sheet needs to be folded, the sheet is placed on the folding table 23 and the positions of the sheet to be bent are aligned with the connection between the main body 231 and each folding part 232. Then, the pressing mechanism 3 presses and fixes the sheet, and each driving component 22 drives the folding frame 21 to rotate. This causes each folding frame 21 to drive each folding part 232 to rotate around the connection between each folding part 232 and the main body 231, thereby folding the sheet located at each folding part 232 toward the sheet located near the main body 231, until the sheet is folded to a suitable angle, thus completing the folding of the sheet and forming a specific angle or layered structure. This makes sheet folding simpler and more convenient, and improves the problem that the sheet folding process is more complicated by alternating between vertical and horizontal folding mechanisms.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
