Therefore, the directional terms used are for illustration rather than to limit the present invention.

[0041] The present invention will be further described below in conjunction with the drawings and preferred embodiments.

[0042] Embodiment: An automatic wire inserting device for a new energy flat wire motor. Refer to the attached Figure 1 - attached Figure 15 , including a pre-wire inserting mechanism 1, a stator positioning mechanism 2, a wire cup gripper 4, and a truss 3. The pre-wire inserting mechanism 1 is used to pre-position flat wires in the arrangement for insertion into the stator to form a stator wire group; the stator positioning mechanism 2 is used to position the stator; the wire cup gripper 4 is used to pull out the stator wire group pre-positioned at the pre-wire inserting mechanism 1 and can insert the pulled-out stator wire group into the stator; the wire cup gripper 4 slides between the stator positioning mechanism 2 and the pre-wire inserting mechanism 1 under the action of the truss 3.

[0043] The flat wires are pre-wired by the pre-wire inserting mechanism 1 to form a stator wire group. The wire cup gripper 4 slides to the pre-wire inserting mechanism 1 under the action of the truss 3, grabs the stator wire group pre-formed by pre-wiring in the pre-wire inserting mechanism 1, and then moves to the stator positioning mechanism 2 under the action of the truss 3. The stator wire group is inserted into the stator core through the wire cup gripper 4.

[0044] Specifically, the pre-wire inserting mechanism 1 includes a wire cup mold 11. The wire cup mold 11 is a copy structure of the stator. A number of wire grooves for pre-inserting flat wires are arranged outside the wire cup mold 11, and the height of the wire cup mold 11 is less than the length of the flat wire. Through the setting of the wire cup mold 11, flat wires can be inserted into the wire grooves of the wire cup mold 11 in sequence by a robot or manually to form a stator wire group.

[0045] Specifically, the pre-wire inserting mechanism 1 further includes a rotating shaft 12. The rotating shaft 12 is fixed at the bottom of the wire cup mold 11 and rotates around the circumferential axis of multiple flat wires on the wire cup mold 11. Through the setting of the rotating shaft 12, the wire cup mold 11 can be driven to rotate during the process of inserting flat wires into the wire cup mold 11, facilitating the sequential insertion of flat wires into the wire cup mold 11.

[0046] Specifically, the pre-wire inserting mechanism 1 further includes a lifting disk 13. The lifting disk 13 is sleeved outside the rotating shaft 12 and can slide up and down. One end of the bottom of the flat wire contacts the top of the lifting disk 13. Through the setting of the lifting disk 13, the flat wire can be pushed to slide up and down on the wire cup, thereby realizing the combing of the flat wire. Also, when the wire cup gripper 4 grabs the flat wire, the flat wire can be pushed upward by the upward movement of the lifting disk 13.

[0047] Specifically, the stator positioning mechanism 2 includes a positioning disk 23. The top of the positioning disk 23 cooperates with the bottom of the stator core to realize the positioning of the stator core.

[0048] Specifically, the stator positioning mechanism 2 further includes a paper protection assembly. When the flat wires are inserted into the stator core, the paper protection assembly is used to protect the insulating paper in the stator core to prevent the insulating paper from moving downward when the flat wires are inserted. The paper protection assembly includes paper protection needles 24. A plurality of paper protection needles 24 are provided. The plurality of paper protection needles 24 are arranged around the stator core. The length direction of the paper protection needles 24 is arranged along the radial direction of the stator core. The paper protection needles 24 can slide along their own length directions. A plurality of installation grooves for installing flat wires are provided outside the stator core. An insulating paper attached to the groove wall of each installation groove is pre-installed in each installation groove. A paper protection needle 24 corresponds to each pair of adjacent insulating papers. The end of the paper protection needle 24 is inserted between the two adjacent insulating papers by sliding and is attached to the side of the two adjacent insulating papers close to each other.

[0049] Specifically, the paper protection mechanism further includes a transmission assembly 5. The transmission assembly 5 is used to drive the paper protection needles 24 to move.

[0050] Specifically, the stator positioning mechanism 2 further includes a sliding seat 22. A positioning disc 23 is fixedly connected to the top of the sliding seat 22. A transverse track 21 is provided below the sliding seat 22. The sliding seat 22 slides on the transverse track 21. One end of the transverse track 21 is located below the truss 3 to facilitate the wire cup gripper 4 to insert the flat wires into the stator core, and the other end is used to send the stator core to the positioning disc 23.

[0051] Specifically, the wire cup gripper 4 includes a wire combing assembly 44 and an inner wire supporting assembly 43. The wire combing assembly 44 can limit the flat wires from the outside of the plurality of flat wires arranged in a surrounding manner and can comb the plurality of flat wires to position the plurality of flat wires. The inner wire supporting assembly 43 can limit the flat wires from the inside of the plurality of flat wires arranged in a surrounding manner to cooperate with the wire combing assembly 44 to clamp the flat wires. The inner wire supporting assembly 43 can move up and down to drive the flat wires to move up and down to pull out the flat wires from the mold and press the flat wires into the stator.

[0052] When it is necessary to pull out the flat wires from the wire cup mold 11, through the movement of the gripper, the inner wire supporting assembly 43 is inserted into the plurality of flat wires arranged in a surrounding manner. The wire combing assembly 44 is located outside the plurality of flat wires arranged in a surrounding manner. The inner wire supporting assembly 43 and the wire combing assembly 44 respectively act in opposite directions from the inside and outside to clamp the flat wires, and the wire combing assembly 44 can also comb and position the plurality of flat wires. Then the inner wire supporting assembly 43 moves upward to pull out the flat wires from the wire cup mold 11. Then the gripper moves to the stator. By moving the inner wire supporting assembly downward, the flat wires are inserted into the stator.

[0053] Specifically, the wire cup gripper 4 includes a press-fitting assembly 42. The press-fitting assembly 42 includes a press-fitting bracket 422 and a press head 421. The press-fitting bracket 422 can move up and down, and the press head 421 is fixedly connected to the top of the press-fitting bracket 422. A press-fitting groove is provided at the bottom of the press head 421, and the shape of the press-fitting groove matches the shape of the crown section formed at the top of the flat wire. The press head 421 is arranged above the inner wire support assembly 43. Through the setting of the press head 421, when the flat wire is press-fitted into the stator, the flat wire can be press-fitted into the stator by the downward movement of the press head 421.

[0054] Specifically, the inner wire support assembly 43 includes a fixed cylinder 431, inner wire support shoes 432, and a power member 433. The fixed cylinder 431 can slide up and down in the vertical direction; the inner wire support shoes 432 are arranged around the fixed cylinder 431 and can slide on the fixed cylinder 431 in the radial direction of the fixed cylinder 431. Each inner wire support shoe 432 corresponds to at least one flat wire and can be tightened against the inner side of the corresponding flat wire; the power member 433 is used to drive the plurality of inner wire support shoes 432 to slide.

[0055] Under the action of the power member 433, the inner wire support shoes 432 can move outward in the radial direction of the fixed cylinder 431 to be tightened against the inner side of the flat wire, or move inward to disengage from the inner side of the flat wire. Here, the inner side of the flat wire refers to the side of the plurality of flat wires arranged in a ring that is close to the center of the ring, and the outer side of the flat wire refers to the side of the plurality of flat wires arranged in a ring that is away from the center of the ring.

[0056] Specifically, the power member 433 includes a connecting block 4332, a rocker 4333, and a guide block 4334. The connecting block 4332 is arranged inside the fixed cylinder 431 and can slide up and down inside the fixed cylinder 431; a rocker 4333 is hinged to each inner wire support shoe 432, and the end of the rocker 4333 away from the inner wire support shoe 432 is hinged to the connecting block 4332; each guide block 4334 corresponds to an inner wire support shoe 432, and the guide block 4334 is arranged at the bottom of the corresponding inner wire support shoe 432. The inner wire support shoe 432 is slidably connected to the corresponding guide block 4334 to limit the inner wire support shoe 432 from sliding in the radial direction of the fixed cylinder 431.

[0057] During the up and down movement of the connecting block 4332, it can drive the plurality of inner wire support shoes 432 to slide on the plurality of guide blocks 4334 respectively through the plurality of rockers 4333, so that the flat wire can be tightened and loosened simultaneously by the plurality of inner wire support shoes 432.

[0058] Specifically, the power member 433 further includes an inner wire support cylinder 4331 fixedly connected inside the fixed cylinder 431. The inner wire support cylinder 4331 is in transmission connection with the connecting block 4332 to drive the connecting block 4332 to move up and down.

[0059] Specifically, the wire cup gripper 4 also includes a fixing assembly 41, and the press-fitting assembly 42, the wire combing assembly 44 and the inner wire supporting assembly 43 are all arranged on the fixing assembly 41. The fixing assembly 41 includes a fixing plate 411, a middle fixing bracket 412 fixedly connected to one side of the top of the fixing plate 411, and an upper fixing bracket 413 fixedly connected to the top of the middle fixing bracket 412; the wire combing assembly 44 is arranged at the bottom of the fixing plate 411, the inner presenting assembly is arranged on the upper fixing bracket 413, and the fixing plate 411 is provided with a through hole for the inner wire supporting assembly 43 to pass through.

[0060] Specifically, the press-fit bracket 422 of the press-fit assembly 42 is slidably connected to the middle fixed bracket 412, and a press-fit electric cylinder 423 is fixedly connected to the upper fixed bracket 413. The press-fit electric cylinder 423 is transmission-connected to the press-fit bracket 422 to drive the press-fit bracket 422 to move up and down.

[0061] Specifically, an inner support wire longitudinal electric cylinder 434 is provided on the press-fit bracket 422, and a lifting plate is fixedly connected to the top of the fixed cylinder 431. The inner support wire longitudinal electric cylinder 434 is transmission-connected to the lifting plate to drive the fixed cylinder 431 to move up and down through the lifting plate. Specifically, four optical axes vertically passing through the fixed bracket are fixedly connected to the lifting plate, and the optical axes can guide the sliding direction of the lifting plate.

[0062] Specifically, the inner support wire assembly 43 further includes a limit block 4335, which is arranged below the connection block 4332 and connected to the fixed cylinder 431. When the inner support wire shoe 432 is tightly supported on the inner side of the flat wire, the connection block 4332 is pressed against the top of the limit block 4335 to prevent the connection block 4332 from continuing to move downward and causing compression and damage to the flat wire. The limit block 4335 is threadedly connected to the fixed cylinder 431, and the height of the top of the connection block 4332 can be adjusted by rotating the connection block 4332, and the lowest height of the connection block 4332 sliding downward can be adjusted, thereby adjusting the farthest distance that the inner support wire shoe 432 slides outward, and thus can adapt to flat wires of different sizes.

[0063] Specifically, the combing wire assembly 44 includes a pressure ring 441 and combing wire teeth 442, and the pressure ring 441 is surrounded by the outer sides of multiple flat wires arranged in a circle; the combing wire teeth 442 are provided in plurality, and the length direction of the combing wire teeth 442 is arranged along the radial direction of the pressure ring 441 and the combing wire teeth 442 can slide along their own length direction, and there is a combing wire tooth 442 corresponding to each adjacent flat wire, and the end of the combing wire tooth 442 close to the flat wire can be inserted between the corresponding adjacent two flat wires.

[0064] By setting the pressure ring 441 in cooperation with the inner support wire assembly 43, the flat wire can be clamped in the middle; and by setting the combing wire teeth 442, after the combing wire teeth 442 are inserted between the corresponding two adjacent flat wires, the up and down movement of the inner support wire assembly 43 can drive the flat wire to move up and down relative to the combing wire teeth 442, and the flat wire is combed by the combing wire teeth 442, thereby achieving the positioning of the flat wire.

[0065] Specifically, the combing assembly 44 also includes a transmission assembly 5, which is used to drive the multiple combing teeth 442 to move. The structure of the transmission assembly 5 in the wire cup gripper 4 is the same as the structure of the transmission assembly 5 in the paper protection assembly. This embodiment takes the structure of the transmission assembly 5 in the wire cup gripper 4 as an example for explanation. The transmission assembly 5 includes a guide plate 53, a pin shaft 56 and an active plate 52. The guide plate 53 is set in a circular ring shape coaxial with the pressure ring 441. The guide plate 53 is respectively provided with multiple guide grooves 531 corresponding to the multiple combing teeth 442. The guide grooves 531 are provided on the guide plate 53. The groove 531 is arranged along the radial direction of the guide disk 53; each combing tooth 442 is fixedly connected to a pin shaft 56 inserted into the corresponding guide groove 531 of the combing tooth 442; the active disk 52 is arranged in a circular ring shape coaxial with the pressure ring 441, and the active disk 52 can rotate around its own axis. A plurality of guide grooves 521 are respectively arranged on the active disk 52 corresponding to the plurality of pin shafts 56, and the guide grooves 521 are arranged so that the distance from the axis of the active disk 52 gradually decreases from one end to the other end, and the pin shaft 56 is inserted into the corresponding guide groove 521.

[0066] By setting the guide groove 531 on the guide plate 53, the pin shaft 56 can only slide along the radial direction of the guide plate 53, that is, the combing teeth 442 can only slide along their own length direction. When the active plate 52 rotates, the position of the pin shaft 56 in the guide groove 521 changes, so that the distance between the pin shaft 56 and the axis of the guide plate 53 changes, which drives the pin shaft 56 to slide in the guide groove 531, thereby driving the combing teeth 442 to slide along their own length direction, and through the rotation of the active plate 52, multiple combing teeth 442 can be driven to move at the same time.

[0067] Specifically, positioning grooves 532 corresponding to the plurality of combing teeth 442 are respectively provided at the bottom of the guide plate 53 . The combing teeth 442 pass through the corresponding positioning grooves 532 and can slide in the positioning grooves 532 along the radial direction of the guide plate 53 .

[0068] Specifically, the transmission assembly 5 also includes a mounting plate 51, which is arranged in a circular ring shape and is coaxial with the pressure ring 441. The pressure ring 441, the guide plate 53 and the active plate 52 are all arranged on the mounting plate 51. The mounting plate 51 is connected to a combing electric cylinder that is transmission-connected to the active plate 52, and the combing electric cylinder is used to drive the active plate 52 to rotate.

[0069] Specifically, the transmission assembly 5 further includes a plurality of guide shafts 54. The guide shafts 54 are vertically arranged and pass upward through the fixing plate 411. The mounting plate 51 is fixed to one end of the bottom of the guide shaft 54. The guide shaft 54 can move up and down on the fixing plate 411 and can be fixed on the fixing plate 411. At one end of the top of the plurality of guide shafts 54, a baffle 55 is fixedly connected. The baffle 55 is used to prevent the guide shaft 54 from disengaging downward from the fixing plate 411.

[0070] The fixing plate 411 of the transmission assembly 5 in the stator positioning mechanism 2 is fixedly connected to the sliding seat 22.

[0071] Specifically, a plurality of wire combing assemblies 44 are provided. The plurality of wire combing assemblies 44 are arranged in the vertical direction, and the plurality of wire combing assemblies 44 act on different heights of the flat wire respectively.

[0072] In the wire cup gripper 4, two wire combing assemblies 44 are provided, namely an upper wire combing assembly 44 and a lower wire combing assembly 44.

[0073] A plurality of flat wires arranged in a circular pattern on the wire cup mold 11 together form a stator wire group. In this embodiment, the working process of grasping and lifting the stator wire group from the wire cup mold 11 is as follows: The gripper moves to the wire cup mold 11 and sleeves the upper and lower wire combing assemblies 44 outside the stator wire group. Then, the inner support wire longitudinal electric cylinder 434 moves downward, inserts the fixing cylinder 431 into the stator wire group. Then, the inner support wire cylinder 4331 acts, driving the inner support wire hoof 432 to expand outward and tightly support the inner side of the stator wire group, that is, tightly support the inner side of the flat wire. Then, the wire combing teeth 442 of the upper and lower wire combing assemblies 44 are inserted inward between adjacent flat wires. After that, the inner support wire longitudinal electric cylinder 434 and the press-fitting electric cylinder 423 move upward together to pull out the stator wire group from the wire cup mold 11.

[0074] When the wire cup gripper 4 inserts the stator wire group into the stator, the gripper moves above the stator. The inner support wire longitudinal electric cylinder 434 moves downward to insert one end of the bottom of the stator wire group into the stator. Then, the press-fitting electric cylinder 423 moves downward and at the same time the inner support wire electric cylinder contracts upward, so that the position of the fixing cylinder 431 remains unchanged while the pressing head 421 moves downward to press-fit the stator wire group into the stator. And as the pressing head 421 presses down, the wire combing teeth 442 of the upper and lower wire combing assemblies 44 are sequentially retracted outward to prevent blocking the pressing head 421 until the stator wire group is pressed in place.

[0075] Specifically, the fixing plate 411 in the fixing assembly 41 is connected to the truss 3. The fixing assembly 41 can slide along the length direction of the truss 3 on the truss 3 and can slide vertically.

[0076] The flat wires are inserted into the wire cup die 11 in sequence by a manipulator or manually. Then, the up-and-down movement of the lifting plate 13 drives the flat wires to move up and down on the wire cup die 11 to realize the combing of the flat wires. After that, the movement of the wire cup gripper 4 on the truss 3 makes the wire cup gripper 4 move above the wire cup die 11. Then, the wire cup die 11 moves downward to grab the stator wire group composed of the flat wires on the wire cup die 11, so that the stator wire group is separated from the wire cup die 11. After that, the movement of the wire cup gripper 4 on the truss 3 makes the wire cup gripper 4 move above the stator core in the stator positioning mechanism 2. At this time, the multiple paper protecting needles 24 in the stator positioning mechanism 2 press the corresponding insulating paper onto the stator core. Then, the stator wire group is pressed downward onto the stator core by the wire cup gripper 4. And when the flat wire approaches the paper protecting needle 24, the paper protecting needle 24 moves out of the stator core. After that, the wire cup gripper 4 completes the pressing and installation of the stator wire group.
