DETAILED DESCRIPTION
[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0019] like Figure 1-Figure 3As shown, an automatic wire-inserting device for the stator of an auxiliary drive motor of a new energy vehicle comprises a frame 1, a workbench 2, a wire-inserting die 3 fixed on the workbench 2, and a wire-pushing mechanism 4 mounted on the frame 1 and cooperating with the wire-inserting die 3. A wire sleeve mechanism 5 is provided on one side of the wire-inserting die 3. The wire sleeve mechanism 5 comprises a sleeve seat 51, a slide rail 511 is provided on the sleeve seat 51, and two symmetrically arranged clamping arms 52 are slidably connected to the slide rail 511.

The outer wall is fitted with a clearance groove 522, and a gear 53 is rotatably provided on the sleeve 51, which is meshed with the rack 521 in a one-to-one manner. The two gears 53 are meshed to drive the two clamping arms 52 to move away or approach synchronously along the slide rail 511. The sleeve 51 is provided with a first servo motor 54 that can drive the gear 53 to rotate. The upper end surface of the clamping arm 52 is embedded with a first pressure sensor 55 along the edge of the clearance groove 522. A lifting mechanism 6 is provided on one side of the wire inserting mold 3, and the lifting mechanism 6 includes a bracket 61 and a first screw rod 62. , the second servo motor 63, the first screw rod 62 is rotatably connected to the bracket 61, the second servo motor 63 is fixed to the bracket 61 to drive the first screw rod 62 to rotate, the first screw rod 62 is threadedly connected to the sleeve 51 to drive the wire sleeve mechanism 5 to move vertically along the first screw rod 62, the frame 1 is provided with a transverse mechanism 7, the workbench 2 is provided with a strip slide hole 21, the transverse mechanism 7 is located below the strip slide hole 21, the transverse mechanism 7 includes a rotation device along the length direction of the strip slide hole 21, The second screw rod 71 is provided with a moving block 72 threadedly connected to the second screw rod 71, and the frame 1 is provided with a third servo motor 73 that can drive the second screw rod 71 to rotate. The bracket 61 is fixedly connected to the upper end of the moving block 72 and can slide along the strip slide hole 21. The bracket 61 is provided with a servo driver 8, and the workbench 2 is provided with a PLC control system 22 coupled to the servo driver 8. The servo driver 8 is coupled with the first pressure sensor 55, the first servo motor 54, the second servo motor 63 and the third servo motor 73.
[0020] Furthermore, the wire pushing mechanism 4 includes a cylinder 41, a lifting plate 42, a guide light shaft 43 and a pushing head 44 fixed to the upper end of the lifting plate 42. The lifting plate 42 is slidably sleeved outside the guide light shaft 43. The telescopic end of the cylinder 41 is fixedly connected to the lifting plate 42 to drive the pushing head 44 to shuttle inside the wire embedding mold 3.
[0021] In actual application, the PLC control system 22 is used to program and store instructions for performing operations such as logical operations, sequential control, timing, counting and arithmetic operations. The servo driver 8 serves as an actuator, receives preset signals from the PLC control system 22 and the first pressure sensor 55, and converts them into actual power signals according to the preset to control the first servo motor 54, the second servo motor 63 and the third servo motor 73. First, the third servo motor 73 drives the second screw rod 71 to rotate so that the moving block 72 drives the bracket 61 to slide along the strip slide 21, so that the wire sleeve mechanism 5 is away from the wire inserting die 3, avoiding The wire sleeve mechanism 5 is prevented from interfering with the coil embedding. Then, the coil is embedded in the wire embedding mold 3 according to the design, and the stator core is sleeved on the wire embedding mold 3. The upper end of the stator core is fixed. Then, the third servo motor 73 is restarted to drive the second screw rod 71 to rotate so that the moving block 72 drives the bracket 61 to slide along the strip slide 21, so that the wire sleeve mechanism 5 is close to the wire embedding mold 3. Then, the first servo motor 54 starts to drive the gear 53 to rotate. The gear 53 rotates and drives the rack 521 to slide along the slide rail 511, so that the two clamping arms 52 are close to each other and fit together. The two clamping arms 52 are enclosed and fit on the outer peripheral wall of the wire embedding mold 3. At this time, it can be started. The second servo motor 63 drives the first screw rod 62 to rotate, thereby driving the wire sleeve mechanism 5 to rise. When the first pressure sensor 55 abuts against the lower end surface of the stator core, the signal is fed back to the servo driver 8, and the second servo motor 63 is controlled to be closed through the preset signal. At this time, the cylinder 41 starts to drive the lifting plate 42 to rise, so that the push head 44 penetrates into the interior of the wire embedding mold 3 from below until the coil is accurately embedded in the wire embedding groove of the stator core. During this period, the coil does not directly contact the lower end of the stator core, but contacts the clamping arm 52. The clamping arm 52 plays a protective and fixing role to prevent the coil from being mechanically damaged during the wire embedding process. , such as scratches and bending caused by friction with the iron core, to ensure that the copper wire maintains a stable posture during the wire embedding process to avoid dislocation or loosening. The clamping arm 52 also plays a guiding and positioning role. The design of the giveway groove 522 is often matched with the structure and function of the wire embedding mold 3 and the stator core wire embedding groove, which can guide the copper wire accurately into the winding groove of the motor stator, and ensure that the copper wire is wound according to the predetermined path and position, thereby improving the accuracy and efficiency of wire embedding, reducing the friction and wear of the coil surface paint and the stator core surface. After the wire embedding is completed, the wire sleeve mechanism 5, the wire pushing mechanism 4, the lifting mechanism 6 and the transverse movement mechanism 7 are reset according to the member path.
[0022] In this embodiment, if Figure 2 As shown, a second pressure sensor 56 is embedded on the lower end surface of the clamping arm 52 along the edge of the clearance groove 522 , and the second pressure sensor 56 is coupled to the servo driver 8 .
[0023] In actual production, after manually putting on the wire sleeve, the operator often presses down the wire sleeve gently. The purpose is to make the coil denser and preliminarily straighten the coil, make the wire embedding process smoother, and improve the accuracy and efficiency of wire embedding. By embedding a second pressure sensor 56 along the edge of the yield groove 522 on the lower end face of the clamping arm 52, and programming the preset pressure parameters through the PLC control system 22, when the two clamping arms 52 are fitted together, the second servo motor 63 can be started to drive the wire sleeve mechanism 5 to descend, so that the lower end face of the clamping arm 52 presses down the coil. When the pre-set pressure load is reached, the servo driver 8 automatically controls the second servo motor 63 to turn off.
[0024] Furthermore, the clamping arm 52 is made of polyetheretherketone (PEEK) or polyphenylene sulfide (PPS), and the edge of the clearance groove 522 is chamfered by 1-2 mm. PEEK or PPS is an engineering-grade plastic material that is resistant to high temperatures, corrosion, and wear, and has excellent self-lubricating properties, which can improve the accuracy and efficiency of wire insertion and reduce friction and wear on the coil surface coating.
[0025] Furthermore, one of the clamping arms 52 has a plug 523 on its inner side, and the other clamping arm 52 has a slot 524 on its inner side. When the two clamping arms 52 are close to and fitted together, the plug 523 is inserted into the slot 524, which serves to limit the mutual position of the two clamping arms 52 and improve the stability of the wire embedding process.
[0026] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
