Abstract
Description
Technical Field
[0001] This invention relates to the field of motor stator manufacturing technology, and in particular to a stator flat wire separating and clamping mechanism and a stator production line. Background Technology
[0002] Driven by the rapid development of new energy vehicles, industrial servo systems, and other fields, drive motors, as core power units, are evolving towards higher power density and higher efficiency. Flat wire motors (also known as hairpin motors) have become the current mainstream technology due to their advantages such as high slot fill factor and good heat dissipation.
[0003] One of the core processes in stator manufacturing for flat wire motors is inserting pre-formed U-shaped hairpin wires into the stator core slots. This process can be divided into two key steps: "wire separation" and "wire insertion." The wire separation process aims to separate, position, and arrange stacked hairpin wire bundles in a preset order for easy insertion. Its accuracy and efficiency directly determine the success rate of subsequent wire insertion and the overall production cycle time. Currently, the automated wire separation equipment commonly used in the industry employs a multi-channel independent drive combined with multi-jaw collaborative operation scheme for its wire clamping and positioning mechanism. Each channel is equipped with two independent jaws, each clamping two wire leads of the same U-shaped hairpin. Through precise control of multiple drive units, the positioning and transfer of the wire leads are achieved.
[0004] However, different stator models have varying lead pitches for the hairpin wires, and the U-shaped hairpin structure is asymmetrical. When the production line needs to change product models, the positions of all grippers on the splitting mechanism must be readjusted. Due to the large number of grippers, the adjustment work is extremely cumbersome and time-consuming, reducing the production efficiency of flat wires. Some existing equipment is equipped with gripper modules of various specifications, allowing for the replacement of the entire gripper module to accommodate hairpins with different lead pitches, but this is costly. Summary of the Invention
[0005] The purpose of this invention is to provide a stator flat wire splitting clamping mechanism and a stator production line. The stator flat wire splitting clamping mechanism can quickly adjust the overall position of the clamping assembly and the spacing between the two clamping parts. It is simple and convenient to operate, saves time, improves the production efficiency of flat wire, and has low cost.
[0006] To achieve this objective, the present invention adopts the following technical solution:

[0010] A driving component is drivingly connected to two clamping components, and the driving component can drive the two clamping components to move closer to each other to clamp the lead or move away from each other to release the lead.
[0011] An adjustment assembly includes a shape-changing rod and an adjustment block. The shape-changing rod is mounted on the frame and extends along the first direction. The length of the shape-changing rod is adjustable. The position of the adjustment block is adjustablely connected to the shape-changing rod. Both clamping members are connected to the adjustment block, and one of the clamping members abuts against one end of the shape-changing rod.
[0012] Optionally, the stator flat wire splitting and clamping mechanism further includes a guide rod, which extends along the first direction and is connected to the frame, and both clamping members are slidably connected to the guide rod.
[0013] Optionally, the stator flat wire splitting and clamping mechanism further includes a transmission assembly, both of which are connected to the transmission assembly, which is connected to the adjusting block. The transmission assembly can drive the two clamping members to move closer to or further away from each other.
[0014] Optionally, the transmission assembly includes a first transmission rod and two second transmission rods. Along the axial direction of the first transmission rod, the center position of the first transmission rod is rotatably connected to the adjusting member, and the two second transmission rods are respectively rotatably connected to the two ends of the first transmission rod. The clamping member corresponds one-to-one with the second transmission rod and is rotatably connected to the second transmission rod.
[0015] Optionally, the driving component is a cylinder, the driving component is mounted on the adjusting block, and the piston of the driving component is connected to one of the clamping components.
[0016] Optionally, the adjustment assembly further includes a first locking component. The adjustment block is provided with a mounting hole and a gap communicating with the mounting hole. The changing rod passes through the mounting hole. The first locking component is connected to the adjustment block and can adjust the width of the gap.
[0017] Optionally, the changing rod includes a first sub-rod, a second sub-rod, and a second locking component. The first sub-rod is tunably connected to the second sub-rod along the first direction, and the second locking component can lock and fix the first sub-rod and the second sub-rod.
[0018] Optionally, the changing rod is detachably connected to the frame.
[0019] Optionally, the stator flat wire splitting and clamping mechanism further includes a lifting assembly, which is mounted on the frame and driven to the hook, and can drive the hook to move vertically.
[0020] On the other hand, a stator production line is provided, including a wire splitting station and a wire insertion station arranged in sequence, wherein the aforementioned stator flat wire splitting clamping mechanism is provided on the wire splitting station.
[0021] The beneficial effects of this invention are:
[0022] This invention provides a stator flat wire sorting and clamping mechanism and a stator production line. The stator flat wire sorting and clamping mechanism includes a frame, a clamping assembly, a driving component, and an adjusting assembly. The frame is equipped with hooks to which the flat wire overlaps. The clamping assembly includes two clamping members, which are spaced apart along a first direction and correspond one-to-one with two leads of the flat wire. The clamping members can clamp the corresponding leads. The driving component is connected to the two clamping members and can drive the two clamping members to move closer together to clamp the leads or move away from each other to release the leads.

The adjusting block is adjustablely connected to the changing rod. Both clamping members are connected to the adjusting block, with one clamping member abutting against one end of the changing rod. Since one of the clamping components abuts against one end of the changing rod, the position of the clamping component can be adjusted by adjusting the length of the changing rod, thereby adjusting the distance between the two clamping components so that the clamping assembly can clamp wires with different spacings. When the flat wire overlaps the hook, the asymmetry of the U-shaped flat wire structure will cause the two wires to be asymmetrical about the hook. At this time, the position of the two clamping components can be adjusted by adjusting the position of the adjusting block, so that the center of the line connecting the two clamping components coincides with the center of the line connecting the two wires, so that the two clamping components can clamp the corresponding wires simultaneously. The stator flat wire splitting and clamping mechanism of the present invention can quickly adjust the overall position of the clamping assembly by adjusting the position of the adjusting block; and can quickly adjust the distance between the two clamping components by adjusting the length of the changing rod. The adjustment method is simple and convenient, saving adjustment time and improving the production efficiency of flat wire. Moreover, there is no need to replace the clamping assembly, which improves the versatility of the stator flat wire splitting and clamping mechanism and reduces costs. Attached Figure Description

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0033] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0034] like Figures 1 to 4As shown, this embodiment provides a stator flat wire splitting and clamping mechanism. The stator flat wire splitting and clamping mechanism includes a frame 1, a clamping assembly 2, a driving component 3, and an adjusting assembly 4. The frame 1 is provided with hooks 11, and the flat wire 100 overlaps the hooks 11. The clamping assembly 2 includes two clamping members 21, which are spaced apart along a first direction and correspond one-to-one with the two leads of the flat wire 100. The clamping members 21 can clamp the corresponding leads. The driving component 3 is driven and connected to the two clamping members 21, and can drive the two clamping members 21 to move closer to each other to clamp the leads or move away from each other to release the leads. The adjusting assembly 4 includes a changing rod 41 and an adjusting block 42. The changing rod 41 is mounted on the frame 1 and extends along the first direction. The length of the changing rod 41 is adjustable. The adjusting block 42 is adjustablely connected to the changing rod 41. Both clamping members 21 are connected to the adjusting block 42, and one of the clamping members 21 abuts against one end of the changing rod 41.
[0035] Since one of the clamping members 21 abuts against one end of the changing rod 41, the position of the clamping member 21 can be adjusted by adjusting the length of the changing rod 41, thereby adjusting the distance between the two clamping members 21 so that the clamping assembly 2 can clamp wires with different spacing. When the flat wire 100 overlaps the hook 11, the asymmetry of the U-shaped flat wire 100 structure will cause the two wires to be asymmetrical about the hook 11. At this time, the position of the two clamping members 21 can be adjusted by adjusting the position of the adjusting block 42, so that the center of the line connecting the two clamping members 21 coincides with the center of the line connecting the two wires, so that the two clamping members 21 can clamp the corresponding wires simultaneously. The stator flat wire splitting clamping mechanism of this embodiment can quickly adjust the overall position of the clamping assembly 2 by adjusting the position of the adjusting block 42; and can quickly adjust the distance between the two clamping members 21 by adjusting the length of the changing rod 41. The adjustment method is simple and convenient, saves adjustment time, and improves the production efficiency of the flat wire 100. Furthermore, it eliminates the need to replace clamping component 2, improving the versatility of the stator flat wire splitting clamping mechanism and reducing costs. The first direction is... Figure 1 The X direction in the diagram refers to a direction within the horizontal plane. The crown of the flat line 100 overlaps with the hook 11, and the two leads are spaced apart along the first direction.
[0036] Optionally, the changing rod 41 is detachably connected to the frame 1, thereby allowing for the replacement of changing rods 41 of different lengths, increasing the adjustment range of the distance between the two clamping members 21, and further improving the versatility of the stator flat wire separating and clamping mechanism. Specifically, the frame 1 is provided with a slot, in which the changing rod 41 is engaged. In other embodiments, the changing rod 41 can also be connected to the frame 1 by screws.
[0037] Optionally, see Figure 2 and Figure 3The changing rod 41 includes a first sub-rod 411, a second sub-rod 412, and a second locking component 413. The first sub-rod 411 is adjustablely connected to the second sub-rod 412 along a first direction, and the second locking component 413 can lock and fix the first sub-rod 411 and the second sub-rod 412. This configuration facilitates adjustment of the length of the changing rod 41 and simplifies its structure, making it easier to process and manufacture.
[0038] Specifically, the first sub-rod 411 is cylindrical and connected to the frame 1. An adjusting block 42 is adjustablely connected to the first sub-rod 411. The inner wall of the first sub-rod 411 has an internal thread, and the outer wall of the second sub-rod 412 has an external thread. The second sub-rod 412 is threadedly connected to the first sub-rod 411. By rotating the second sub-rod 412, it can move along a first direction, thereby adjusting the length of the changing rod 41. The second locking component 413 is a nut, threadedly connected to the second sub-rod 412. After adjusting the second sub-rod 412 to a suitable position, rotating the second locking component 413 causes it to abut against the end of the first sub-rod 411, thus locking and fixing the first sub-rod 411 and the second sub-rod 412. In other embodiments, the first sub-rod 411 is cylindrical, the second sub-rod 412 is slidably connected inside the first sub-rod 411, the second locking component 413 is a screw, a threaded hole is provided on the side wall of the first sub-rod 411, the screw is threaded into the threaded hole, and the screw is rotated to abut against the second sub-rod 412 to lock and fix the first sub-rod 411 and the second sub-rod 412.
[0039] Optionally, the adjusting assembly 4 further includes a first locking component. The adjusting block 42 has a mounting hole and a gap communicating with the mounting hole. The changing rod 41 passes through the mounting hole. The first locking component is connected to the adjusting block 42 and can adjust the width of the gap. Adjusting the first locking component increases the width of the gap, thereby increasing the diameter of the mounting hole. The changing rod 41 can move within the mounting hole, thus adjusting the position of the adjusting block 42. After adjusting the adjusting block 42 to a suitable position, adjusting the first locking component decreases the width of the gap, thereby decreasing the diameter of the mounting hole. The inner wall of the mounting hole presses against the adjusting block 42 to fix the adjusting block 42. This configuration facilitates the adjustment of the position of the adjusting block 42.
[0040] Specifically, the first locking component is a locking screw. The adjusting block 42 has a through hole on one side of the gap and a threaded hole on the other side. The locking screw passes through the through hole and is threaded into the threaded hole. By rotating the locking screw, the width of the gap can be adjusted. In other embodiments, the first locking component is a bolt and a nut. The adjusting block 42 has through holes on both sides of the gap. The bolt passes through the two through holes in sequence and is threaded into the nut. By rotating the nut, the width of the gap can be adjusted.
[0041] Optionally, see Figure 2 The stator flat wire separating and clamping mechanism also includes guide rods 5, which extend along a first direction and are connected to the frame 1. Both clamping members 21 are slidably connected to the guide rods 5. By providing guide rods 5, the stability of the two clamping members 21 during movement is improved. Specifically, two guide rods 5 are provided, with both ends of each guide rod 5 fixedly connected to the frame 1. Both clamping members 21 are slidably connected to the two guide rods 5, and the adjusting block 42 is also slidably connected to both guide rods 5, further improving the stability of the two clamping members 21 during movement.
[0042] Optionally, see Figure 2 and Figure 4 The stator flat wire separating and clamping mechanism also includes a transmission assembly 6. Both clamping members 21 are connected to the transmission assembly 6, which is connected to the adjusting block 42. The transmission assembly 6 can drive the two clamping members 21 to move closer or further apart, thereby adjusting the distance between them. Furthermore, when the adjusting block 42 is moved, the transmission assembly 6 can move the two clamping members 21, thereby adjusting the position of the clamping assembly 2.
[0043] Furthermore, the transmission assembly 6 includes a first transmission rod 61 and two second transmission rods 62. Along the axial direction of the first transmission rod 61, the center position of the first transmission rod 61 is rotatably connected to the adjusting block 42. The two second transmission rods 62 are respectively rotatably connected to both ends of the first transmission rod 61. The clamping member 21 corresponds one-to-one with the second transmission rod 62 and is rotatably connected to it. Adjusting the length of the changing rod 41 adjusts the position of the clamping member 21 abutting against one end of the changing rod 41. The first transmission rod 61 and the two second transmission rods 62 drive the other clamping member 21 to move synchronously, causing the two clamping members 21 to move closer or further apart. Since the center of the first transmission rod 61 is rotatably connected to the adjusting block 42, and the two second transmission rods 62 are rotatably connected to the two ends of the first transmission rod 61 respectively, the two clamping parts 21 are located on both sides of the adjusting block 42 along the first direction and are always symmetrical about the adjusting block 42. It is only necessary to make the center of the line connecting the adjusting block 42 and the two leads correspond to each other, so that the two clamping parts 21 correspond to the two leads one by one, which is convenient for adjustment.
[0044] Specifically, one clamping member 21 abuts against one end of the changing rod 41, and the other clamping member 21 is provided with a sliding groove, in which the changing rod 41 is slidably connected. In other embodiments, the transmission assembly 6 includes a first transmission rod 61 and a second transmission rod 62. The first transmission rod 61 is rotatably connected to the adjusting block 42, and the second transmission rod 62 is rotatably connected to the first transmission rod 61. The clamping member 21 abutting against one end of the changing rod 41 is rotatably connected to the second transmission rod 62, and the other clamping member 21 is fixedly connected to the adjusting block 42. The distance between the two clamping members 21 is adjusted by adjusting the position of one clamping member 21.
[0045] Optionally, the drive element 3 is a cylinder, mounted on the adjusting block 42, and its piston is connected to one of the clamping elements 21. By moving the adjusting block 42, the drive element 3 moves synchronously, thereby adjusting the positions of the clamping assembly 2 and the drive element 3. Under the action of the transmission assembly 6, the drive element 3 drives one clamping element 21 to move, thereby causing the other clamping element 21 to move synchronously to clamp the corresponding wire lead. In other embodiments, the drive element 3 can also be an electric cylinder or a hydraulic cylinder.
[0046] Optionally, see Figure 1 The stator flat wire separating and clamping mechanism also includes a lifting assembly 7, which is mounted on the frame 1 and driven by a hook 11. The lifting assembly 7 can drive the hook 11 to move vertically. By setting the lifting assembly 7, the flat wire 100 can be lifted to a position corresponding to the clamping member 21, making it convenient for the clamping member 21 to clamp the wire lead.
[0047] Specifically, the lifting assembly 7 includes a drive motor, a gear, and a rack. The drive motor is mounted on the frame 1 and is driven by the gear. The rack extends vertically and meshes with the gear, and a hook 11 is connected to the rack. The drive motor drives the gear to rotate, thereby moving the rack vertically, which in turn moves the hook 11 vertically. In other embodiments, the lifting assembly 7 includes a drive motor, a lead screw, and a lead screw nut. The lead screw extends vertically, and the lead screw nut is threaded onto the lead screw. The drive motor is driven by the lead screw. The drive motor drives the lead screw to rotate, thereby moving the lead screw nut vertically, which in turn moves the hook 11 vertically.
[0048] This embodiment also provides a stator production line. The stator production line includes a wire sorting station and a wire insertion station arranged sequentially. The wire sorting station is equipped with the aforementioned stator flat wire sorting and clamping mechanism. In this embodiment, the stator production line can quickly adjust the overall position of the clamping assembly 2 by adjusting the position of the adjusting block 42; and can quickly adjust the distance between the two clamping parts 21 by adjusting the length of the changing rod 41. It can quickly adjust according to different types of flat wires 100. The adjustment method is simple and convenient, saves adjustment time, and improves the production efficiency of flat wires 100.
