It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Example 1
[0021] like Figures 1-6 As shown in the figure, the fully direct-drive iron core silicon steel sheet stacking and alignment mechanism provided in this embodiment includes a platform 1, a moving platform 2, a mounting base 4, and a first power assembly 6. Specifically, the moving platform 2 is connected to the platform 1 through a rotation limiting assembly 3, which restricts the platform 1 from rotating relative to the moving platform 2; the mounting base 4 is connected to the moving platform 2 through a movement limiting assembly 5, which restricts the moving platform 2 from linearly moving relative to the mounting base 4; the first power assembly 6 includes a stator 61 and a mover 62 arranged in parallel (forming a linear motor structure), the stator 61 is fixed to the mounting base 4, and the mover 62 is fixed to the platform 1.
[0022] Based on the above structure: When the first power component 6 drives the mobile stage 2 and the platform 1 to move linearly, the stator 61 is energized to guide the mover 62 to move linearly along it. At the same time, the rotation limit component 3 remains locked, and the movement limit component 5 is unlocked. In this structure, the driving force generated by the mover 62 moving along the stator 61 and acting on the platform 1 is parallel to the movement direction of the movement limit component 5, so that the mobile stage 2 can move linearly relative to the mounting base 4. When the platform 1 is driven to rotate by the first power component 6, the stator 61 is energized to guide the mover 62 to move linearly along it. At the same time, the movement limiting component 5 remains locked, and the rotation limiting component 3 is unlocked. In this structure, the driving force generated by the mover 62 moving along the stator 61 and acting on the platform 1 is tangent to the rotation limiting component 3, thereby enabling the platform 1 to rotate relative to the moving stage 2.
[0023] It should be noted that, in order to ensure that the first power assembly 6 can fully meet the requirements for forming the above-mentioned linear motion and rotary motion, it is preferable that the stator 61 and the mover 62 are configured to extend along the moving direction of the moving limiting assembly 5, and the length of the mover 62 is greater than that of the stator 61.
[0024] Referring again to Figure 5, in some embodiments, two sets of the first power assembly 6 are symmetrically arranged relative to the rotation limiting assembly 3. Thus, when the platform 1 is driven to rotate by the first power assembly 6, the movers 62 of the two sets of first power assemblies 6 move in opposite directions; when the moving platform 2 is driven to move linearly by the first power assembly 6, the movers 62 of the two sets of first power assemblies 6 move in the same direction. This structural design provides symmetrical drive for the moving platform 2 and the platform 1, effectively improving the stability of the moving platform 2 and the platform 1 during movement and preventing movement deviation.
[0025] Continue to refer to Figure 5 and Figure 6 As shown, the rotation limiting assembly 3 includes an inner bushing 31 and an outer bushing 32 that are coaxially rotatably fitted. The inner bushing 31 is fixedly installed to the platform 1, and the outer bushing 32 is fixedly installed to the moving platform 2. Thus, when the platform 1 is guided to rotate relative to the moving platform 2 using the rotation limiting assembly 3, the platform 1, driven by the movement of the mover 62 and limited by the rotation of the inner bushing 31, causes the inner bushing 31 to rotate relative to the outer bushing 32.
[0026] To further achieve the locking of the rotation limiting component 3, the inner bushing 31 is preferably constructed as a permanent magnet, and the outer bushing 32 is preferably constructed as an electromagnetic component capable of magnetically engaging with the inner bushing 31. Under this structural design, if the rotation limiting component 3 remains locked, energizing the outer bushing 32 generates a magnetic attraction between the outer bushing 32 and the inner bushing 31, thereby limiting the position of the inner bushing 31 relative to the outer bushing 32, i.e., preventing the platform 1 from rotating relative to the moving platform 2.
[0027] Continue to refer to Figure 6As shown, the mounting base 4 and the movable limiting component 5 are symmetrically arranged in two sets relative to the movable platform 2. The movable limiting component 5 includes a first slide rail 51 and a first slide block 52 that are slidably engaged. The first slide rail 51 is fixedly installed to the movable platform 2, and the first slide block 52 is fixedly installed to the mounting base 4. Thus, when the movable platform 2 is guided to move linearly relative to the mounting base 4 using the movable limiting component 5, the platform 1 and the movable platform 2, under the driving force of the mover 62 and the sliding guidance of the first slide rail 51, realize the movement of the first slide rail 51 relative to the first slide block 52, thereby realizing the linear movement of the movable platform 2.
[0028] To further lock the movement limiting component 5, the movement limiting component 5 also includes a clamp 53 fixedly mounted on the mounting base 4. The clamp 53 is provided with a clamping cavity that can pass through the first slide rail 51. In this structural design, if the movement limiting component 5 remains locked, the clamp 53 is activated to achieve a rigid connection between the clamp 53 and the first slide rail 51. Since the clamp 53 is fixed on the mounting base 4, a rigid connection is achieved between the moving stage 2 and the mounting base 4. That is, in this structural state, the moving stage 2 cannot move linearly relative to the mounting base 4.
[0029] It should be noted that two sets of first slide blocks 52 are arranged on the guide rail 51, relatively distributed on both sides of the clamp 53. This not only ensures the stable sliding of the first slide rail 51 but also effectively disperses the load during movement, improving the rigidity and durability of the overall structure. This symmetrical distribution design helps maintain the balance of the first slide rail 51 and the moving stage 2, reducing off-center loading and vibration, thereby improving alignment accuracy and operational stability. Simultaneously, the combined use of the two sets of first slide blocks 52 enhances the system's impact resistance and extends the device's service life, making it particularly suitable for high-precision and high-load stacking alignment operations.
[0030] In addition, such as Figure 4 As shown, a rotation limiting rod 11 is fixed on the platform 1, and an arc-shaped limiting groove 21 that cooperates with the rotation limiting rod 11 is provided on the moving platform 2. The arc-shaped limiting groove 21 is coaxially engaged with the rotation limiting assembly 3. Thus, when the platform 1 rotates relative to the moving platform 2, the platform 1 drives the rotation limiting rod 11 to rotate synchronously, causing the rotation limiting rod 11 to move relative to the arc-shaped limiting groove 21. The two ends of the arc-shaped limiting groove 21 can effectively limit the maximum displacement of the rotation limiting rod 11, thereby limiting the maximum angle of rotation of the platform 1.
[0031] Of course, a non-contact magnetic encoder can also be installed on the mobile stage 2 for positioning, so as to accurately detect the rotation angle and moving position of the platform 1, thereby ensuring the accuracy of motion positioning during the fine-tuning and alignment of the platform 1.
[0032] In summary, in this embodiment, the specific alignment principle of the alignment mechanism is as follows: When the first power component 6 drives the moving stage 2 and the platform 1 to move linearly, the stator 61 is energized to guide the mover 62 to move linearly along it. At the same time, the outer bushing 32 is energized to magnetically fix the inner bushing 31 (the rotation limiting component 3 remains locked). The clamp 53 is disengaged so that the first slide rail 51 can move along the first slide block 52 (the movement limiting component 5 performs unlocking). In this structure, the driving force generated by the mover 62 moving along the stator 61 and acting on the platform 1 is parallel to the moving direction of the movement limiting component 5, thereby enabling the moving stage 2 to move linearly relative to the mounting base 4. When the platform 1 is driven to rotate by the first power component 6, the stator 61 is energized to guide the mover 62 to move linearly along it, while the outer bushing 32 is de-energized to allow the inner bushing 31 to rotate (the rotation limiting component 3 remains locked). The clamp 53 is activated to fix the first slide rail 51 (the movement limiting component 5 unlocks). In this structure, the driving force generated by the mover 62 moving along the stator 61 and acting on the platform 1 is tangential to the rotation limiting component 3, thereby enabling the platform 1 to rotate relative to the moving stage 2. Example 2
[0033] like Figures 1-7 As shown, this embodiment provides a fully direct-drive core-mounted silicon steel sheet stacking and alignment mechanism, including a platform 1, a moving platform 2, a mounting base 4, a first power assembly 6, a fixed platform 7, and a second power assembly 8. Specifically, the moving platform 2 is connected to the platform 1 via a rotation limiting assembly 3, which restricts the platform 1 from rotating relative to the moving platform 2; the mounting base 4 is connected to the moving platform 2 via a movement limiting assembly 5, which restricts the moving platform 2 from linearly moving relative to the mounting base 4; the fixed platform 7 is connected to the mounting base 4 via a movement guide assembly 9, which restricts the mounting base 4 from linearly moving relative to the fixed platform 7; the first power assembly 6 includes a stator 61 and a mover 62 arranged in parallel (forming a linear motor structure), the stator 61 is fixed to the mounting base 4, and the mover 62 is fixed to the platform 1; the second power assembly 8 is arranged perpendicularly to the first power assembly 6 and the two have the same structure (the stator of the second power assembly 8 is fixed to the fixed platform 7, and the mover is fixed to the mounting base 4).
[0034] Compared to Embodiment 1, in this embodiment, under the combined drive of the first power component 6 and the second power component 8, the platform 1 can perform bidirectional movement in the X and Y directions, thereby enabling the platform 1 to move flexibly to any position in the plane, further expanding the range of motion of the platform 1, and thus more accurately meeting the alignment requirements of the stacking of iron core silicon steel sheets.
[0035] Continue to refer to Figure 7 As shown, in some embodiments, the movable guide assembly 9 includes a slidingly engaged second slide rail 91 and a second slide block 92. The second slide rail 91 is fixedly installed to the mounting base 4, and the second slide block 92 is fixedly installed to the fixed platform 7. Thus, when the movable guide assembly 9 guides the mounting base 4 to move linearly relative to the fixed platform 7, the mounting base 4, driven by the movement of the mover of the second power assembly 8 and guided by the sliding of the second slide rail 91, achieves the movement of the second slide rail 91 relative to the second slide block 92, thereby realizing the linear movement of the mounting base 4.
[0036] In addition, such as Figure 3 As shown, a first movable limiting rod 41 is fixed on the mounting base 4, and a second movable limiting rod 71 that cooperates with the first movable limiting rod 41 is provided on the fixed platform 7. Along the moving direction of the moving guide assembly 9, two sets of the second movable limiting rods 71 are symmetrically arranged relative to the first movable limiting rod 41. Therefore, when the mounting base 4 moves linearly relative to the fixed platform 7, the mounting base 4 drives the first movable limiting rod 41 to move synchronously, causing the first movable limiting rod 41 to move between the two second movable limiting rods 71. By utilizing the two relatively arranged second movable limiting rods 71, the maximum displacement of the first movable limiting rod 41 can be effectively limited, thereby limiting the maximum displacement of the mounting base 4.
[0037] It should also be noted that the symmetrical layout of the double second moving limit rods 71 enables the precise positioning and buffer protection of the moving guide assembly 9 within its stroke range, effectively avoiding the off-center load phenomenon caused by unilateral force, thereby significantly improving the motion stability and repeatability of the mechanism.
