In case of any inconsistency, the meaning set forth in this specification or derived from the content described herein shall prevail. Furthermore, the terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit the scope of this application.

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] Example: like Figure 1 As shown, the present invention provides a segmented winding machine, which includes a conveying module for feeding, fixing and winding the motor stator 4, and a wire conveying module for feeding the motor stator 4 wire.

[0022] The conveying module includes a loading conveyor line 1 and a unloading conveyor line 2 for conveying a tray 3 containing a motor stator 4. Both loading conveyor line 1 and unloading conveyor line 2 adopt existing conveyor belt structures, and the tray 3 containing the motor stator 4 is manually placed on the loading conveyor line 1 and conveyed into the machine. Both loading conveyor line 1 and unloading conveyor line 2 are equipped with lifting mechanisms 5 for lifting the tray 3 on the loading conveyor line 1.

[0023] like Figure 2 , Figure 3As shown, the lifting mechanism 5 includes a fixed base plate 501, which is connected to a fixed top plate 503 via a column 502. A lifting cylinder 504 is provided at the bottom end of the fixed top plate 503, and the cylinder rod of the lifting cylinder 504 passes through the fixed top plate 503 and is connected to a lifting plate 505 for lifting the pallet 3. The cylinder rod of the lifting cylinder 504 drives the lifting plate 505 to rise and fall, thereby lifting or lowering the pallet 3.

[0024] Above the lifting mechanism 5 is a line-changing mechanism 6 for pushing the pallet 3 above the loading conveyor line 1 to the unloading conveyor line 2. The line-changing mechanism 6 pushes the pallet 3 lifted by the lifting mechanism 5 to the unloading conveyor line 2, and then the lifting mechanism 5 of the unloading conveyor line 2 lowers it to the unloading conveyor line 2.

[0025] like Figure 4 As shown, the line-changing mechanism 6 includes a fixed base 601, on which fixed plates 602 are symmetrically arranged. A lead screw structure 603 and a slide rail 605 are provided on the fixed plates 602. The fixed plates 602 are connected to a line-changing moving plate 604 via the lead screw structure 603, and the line-changing moving plate 604 is slidably connected to the fixed plates 602 via the slide rail 605. A line-changing motor 606 is provided on the fixed plates 602. The line-changing motor 606 drives the line-changing moving plate 604 to move via the lead screw structure 603 (in the existing structure, the motor drives the lead screw to rotate, thereby driving the lead screw pair threadedly connected to it to move along the lead screw, and the lead screw pair is fixed to the line-changing moving plate 604). During the movement, the line-changing moving plate 604 slides on the fixed plates 602 via the slide rail 605. The movement of the line-changing moving plate 604 causes the tray 3 to move.

[0026] Above the line changing mechanism 6 is a stator clamping and moving mechanism 7 with xyz three-axis movement function, which is mounted on the bracket 701.

[0027] like Figure 5 As shown, the stator clamping and moving mechanism 7 includes a clamp 702, which is mounted on a movable base 704. The movable base 704 is connected to an xyz three-axis module 703 with xyz three-axis movement. The xyz three-axis module 703 is located at the top of the bracket 701. The xyz three-axis module 703 adopts an existing structure and can drive the clamp 702 to move back, forth, left, right, up, and down. After clamping the motor stator 4 (the entire tooling 911 on which the motor stator 4 is stacked) by the clamp 702, it is moved to the rotary winding mechanism 9.

[0028] A clamping mechanism 8 for clamping the motor stator 4 is provided on the bracket 701. The clamping mechanism 8 includes a plurality of clamping cylinders 801 arranged at the top of the bracket 701, and the cylinder rod at the bottom of the clamping cylinder 801 is connected to the clamping head 802. A limiting block 803 for fixing the motor stator 4 is provided at the bottom end of the clamping head 802. After the clamp 702 clamps the motor stator 4 onto the rotating winding mechanism 9 and then moves away, the clamping cylinders 801 drive the clamping head 802 to press down, and the limiting block 803 fixes the motor stator 4.

[0029] Below the clamping mechanism 8 is a rotating winding mechanism 9 for fixing the motor stator 4 and winding the wire.

[0030] like Figure 6 , Figure 7 As shown, the rotary winding mechanism 9 includes a fixed winding motor 901. The output shaft of the winding motor 901 is equipped with a drive wheel 902, which is connected to several driven wheels 903 via a synchronous belt 904. Tensioning wheels 905, around which the synchronous belt 904 passes, are arranged between the drive wheel 902 and the driven wheels 903, and between adjacent driven wheels 903. A winding structure is provided on each driven wheel 903, including a rotating shaft 906 located at the center of the driven wheel 903, with its bottom end connected to the center of the driven wheel 903. The top end of the rotating shaft 906 is connected to a winding seat 907 for placing the motor stator 4, and a fixing cover 908 is provided over the rotating shaft 906. A wire clamping unit 909 is provided on one side of the winding seat 907 for passing and clamping the wire after stripping, and a stator clamping unit 910 is provided on the other side of the winding seat 907 for clamping the motor stator 4. The wound motor 901 drives the drive wheel 902 to rotate. The drive wheel 902 drives the driven wheel 903 to rotate through the synchronous belt 904 and the tension wheel 905. The rotation of the driven wheel 903 drives the rotating shaft 906 to rotate, which in turn drives the winding seat 907 to rotate, thereby performing the winding work on the motor stator 4 at the top of the winding seat 907.

[0031] like Figure 8 , Figure 9 , Figure 10As shown, two motor stators 4 are stacked on a fixture 911 in an upper-lower layer configuration. The fixture 911 is mounted on a winding base 907. A positioning groove 9111 is provided at the bottom of each motor stator 4. A magnet 9113 and a positioning block 9112 are provided on the fixture 911 to fix the motor stator 4. The magnet 9113, positioning block 9112, and positioning groove 9111 are aligned in a straight line. The positioning block 9112 is inserted into the positioning groove 9111 of the motor stator 4 to secure it and prevent lateral movement. The magnet 9113 is used to attract and fix the motor stator 4, improving stability. A guide rod is provided inside the fixture 911, and a fixing spring 9115 is sleeved on the guide rod. The spring force of the fixing spring 9115 presses the motor stator 4 firmly, further improving stability. In the figure, the two motor stators 4 are stacked on the fixture 911 in an upper-lower layer configuration, with the top of the upper motor stator 4 securely connected to the fixture 911. The tooling 911 is equipped with a transition block 9114, which is used to transition the wire with the sleeve after the lower motor stator 4 has been wound to the upper motor stator 4 for winding.

[0032] like Figure 11 , Figure 12 As shown, the wire clamping unit 909 includes a clamping cylinder 9091 mounted on a fixed cover 908 and two symmetrical clamps 9092 mounted on a winding base 907. The two clamps 9092 are rotatably connected to the fixed cover 908 via a rotating shaft 9094. Each clamp 9092 has a clamping opening 9093 at its top for wire passage. The lower parts of the two clamps 9092 are connected by a spring 9095, and each clamp 9092 has a rotating wheel 9096 at its bottom. A clamping element 9097, adapted to the rotating wheel 9096, is connected to the cylinder rod at the top of the clamping cylinder 9091. The clamping element 9097 is located below the rotating wheel 9096. The wire enters and is conveyed through clamp 9093. Under the action of spring 9095, the lower parts of the two clamps 9092 are pushed outward by spring 9095. The two clamps 9092 rotate under the action of the central rotating shaft 9094, causing the clamps 9093 at the top of the two clamps 9092 to clamp the wire. The clamping cylinder 9091 drives the clamping member 9097 to rise. The clamping member 9097 presses the two rotating wheels 9096 towards the middle, which in turn drives the bottom ends of the two clamps 9092 to move towards the middle, pressing spring 9095. Under the action of the central rotating shaft 9094, the two clamps 9092 rotate, causing the clamps 9093 at the top of the two clamps 9092 to open.

[0033] The stator clamping unit 910 includes a pull-down cylinder 9101 mounted on a fixed cover 908 and a clamping rod 9102 mounted on a winding seat 907. The upper part of the clamping rod 9102 is connected to the winding seat 907 via a spring 9106. The top of the clamping rod 9102 is provided with a clamping inclined surface 9103. A clamping block 9104, which is adapted to the clamping inclined surface 9103, is provided on the fixture 911. The clamping block 9104 is a wedge-shaped block. The cylinder rod at the top of the pull-down cylinder 9101 is connected to a pull-down hook 9105, and the top of the pull-down hook 9105 hooks onto the bottom end of the clamping rod 9102. Under the action of spring 9106, the clamping rod 9102 is pulled upward by an upward force, and the clamping inclined surface 9103 at the top of the clamping rod 9102 pushes the clamping block 9104 forward, thereby clamping the fixture 911 on the winding seat 907. The cylinder rod of the pull-down cylinder 9101 drives the pull-down hook 9105 to descend, and the pull-down hook 9105 pulls the clamping rod 9102 downward. The clamping inclined surface 9103 at the top of the clamping rod 9102 moves downward, releasing the clamping block 9104, thereby releasing the fixture 911 from its fixation.

[0034] First, the pull-down cylinder 9101 moves the clamping inclined surface 9103 downward, releasing the clamping block 9104. After the fixture 911 with the stacked generator stator 4 is placed on the winding seat 907, the pull-down cylinder 9101 moves the clamping inclined surface 9103 upward. Under the action of the second spring 9106, the clamping rod 9102 is pushed upward, pushing the clamping block 9104 forward to fix the fixture 911. Then, the three-dimensional moving platform of the wire stripping assembly 11 moves xyz to transport the wire to the vicinity of the clamp 9093. The clamping cylinder 9091 drives the clamp 9093 to open, and the wire is inserted into the clamp 9093. The clamping cylinder 9091 drives the clamping part 9097 downward. Under the action of the first spring 9095, the clamp 9093 automatically clamps the wire. Then the winding is performed. During the winding, the rotating shaft 906 drives the winding seat 907 to rotate, while the fixed cover 908 and its pull-down cylinder 9101 and clamping cylinder 9091 do not rotate.

[0035] The wire feeding module includes a tension frame mechanism 10 for initial wire feeding and tension control, and a wire stripping assembly 11 for feeding and stripping the wire output from the tension frame mechanism 10.

[0036] like Figure 13As shown, the wire stripping assembly 11 has xyz three-axis movement function. The wire stripping assembly 11 is used to transport the stripped wire to the rotary winding mechanism 9 for winding. The wire stripping assembly 11 is set on the existing three-dimensional moving platform, thereby realizing xyz three-axis movement adjustment, ensuring smooth and accurate wire feeding, and cooperating with the rotary winding mechanism 9 to complete the winding work. The wire stripping assembly 11 includes a wire stripping platform 1101, on which a paint stripping structure 1102, a dust removal structure 1103, a wool felt structure 1104, a sleeve sleeve structure 1105, an auxiliary sleeve structure 1106, and a wire cutting structure 1107 are set.

[0037] like Figure 14 , Figure 15 , Figure 16 As shown, the stripping structure 1102 adopts an existing structure. The stripping structure 1102 includes a stripping motor 11021 and a stripping blade 11022 mounted on the wire stripping platform 1101. The stripping motor 11021 drives the stripping blade 11022 to rotate via an existing synchronous belt 904. The stripping motor 11021 drives the stripping blade 11022 to rotate at high speed to strip the enameled wire. The dust removal structure 1103 includes a dust removal box 11031. The dust removal box 11031 is connected to the dust removal pipe 11034 in sequence via a vacuum generator 11032 and a pipe adapter 11033. A wire nozzle 11035 is provided on the dust removal box 11031. The stripped wire passes through the wire nozzle 11035 on the other side of the dust removal box 11031. The function of the wire nozzle 11035 is to protect the enameled wire as it passes through the dust collection box 11031, preventing the box from scratching it. The blade head of the stripping knife 11022 is inside the dust collection box 11031, while the body is on the outside.

Figure 17 As shown, the sleeve clamping structure 1108 includes a clamping cylinder 11081 mounted on the movable base 704, and a sleeve clamping jaw 11082 connected to the clamping cylinder 11081. The purpose of sleeve clamping is to provide insulation during the transition from the lower motor stator 4 to the upper motor stator 4 during winding, preventing short circuits. A regional fiber optic sensor 1110 is also installed on the stripping platform to detect whether the stripping of the enameled wire is complete.

[0039] The sleeve clamping jaw 11082 of the sleeve clamping structure 1108 picks up the sleeve from the tray 3 and moves it to the auxiliary sleeve structure 1106. The sleeve clamping jaw 11063 extends and clamps the copper wire. The copper wire is sent into the sleeve by the xyz three-axis movement. The sleeve clamping jaw 11082 releases and moves the sleeve on the copper wire backward by the xyz three-axis movement. The sleeve clamping jaw 11082 clamps the sleeve and moves the copper wire forward to insert into the sleeve by the xyz three-axis movement. The above actions are repeated until the sleeve is completely sleeved on the copper wire. The sleeve clamping jaw 11054 of the sleeve sleeve structure 1105 opens and extends to clamp the sleeve. After the moving area fiber optic sensor 1110 is detected, the winding operation is performed.

A wire guide pulley 11091 is connected to the encoder 1109, and a corresponding rotatable wire guide wheel 11092 is provided on the wire guide pulley 11091. The enamel-coated wire after secondary dust removal passes between the wire guide pulley 11091 and the wire guide wheel 11092 to achieve length monitoring.

The wire is output from wire coil 1002, passes sequentially through guide wheel 1003, figure-eight wheel group, guide wheel 2 1004, tension wheel 1008, then through ceramic eye 1010 and through wire guide wheel 1015 into wire stripping assembly 11 for stripping and conveying. Here, winding wheel 1005 is the drive wheel, driven by a motor rotating its center. This is the existing structure, with the motor mounted on wheel plate 1007.

[0043] A tension structure is provided on the wheel plate 1007, including a tension plate 1009.

Figure 1 As shown, the loading conveyor line 1 (which has the same structure as the unloading conveyor line 2) is symmetrically placed on both sides of the bottom end of the pallet 3; II.

The clamp 702 of the stator clamping and moving mechanism 7 takes out the motor stator 4 from the tray 3 and puts it into the rotating winding mechanism 9; IV. After the motor stator 4 is inserted, the clamping mechanism 8 presses down on the motor stator 4; 5. After the motor stator 4 is pressed, the wire is conveyed and the enamel is stripped through the tension frame mechanism 10 and the wire stripping assembly 11. The stripped wire is then transferred to the rotary winding mechanism 9 for winding. 6. After the winding is completed, the stator is removed by the stator clamping and moving mechanism 7 and placed back on the tray 3.
