Description

Technical Field

[0001] The present invention relates to the field of motor winding equipment, and in particular to a winding spindle for motor winding and an operating method thereof. Background Art

[0002] A motor consists of a stator and a rotor. The stator is the stationary part of the motor and includes a stator core and windings wound around the core. The stator windings generate a rotating magnetic field. During the motor manufacturing process, a motor winding system is typically used to wind wire, particularly insulated copper wire, around the stator core. A stator has twelve cores, each of which is wound separately. After winding, the stator is divided into three phases, with four cores representing one phase. These four cores are further divided into two groups, each with two cores, which are typically connected using transition wires. Existing winding equipment for motor stators typically rounds up the twelve cores and then winds each core individually. Because each core is positioned and angled differently after the rounding, the winding nozzle requires numerous auxiliary mechanisms to adjust the nozzle angle and rotate the stator to align the corresponding core with the nozzle. Furthermore, the winding process of the transition wire connecting each group of cores is complex and inefficient. Therefore, the existing motor stator winding mechanism and method should be improved to solve the above problems. Summary of the Invention

When the pushing cylinder pushes the pushing block upward, the lower ends of the two wire clamping blocks move closer to each other under the drive of the wedge-shaped fitting portion and the wedge-shaped fitting groove, and the upper ends of the two wire clamping blocks separate from each other.

[0009] As a preferred solution: at least one magnet is provided on the outer wall of each of the two clamping blocks, and magnets are also provided on the upper end of the clamping seat corresponding to the magnets on the two clamping blocks. The magnets on the clamping seat and the magnets on the clamping blocks are attracted to each other to ensure that the clamping groove between the two clamping blocks always corresponds to the winding groove of the iron core.

[0032] The present invention Figures 1 to 8 As shown, a winding spindle and an operating method for winding a motor include a bracket 10, a jig 20 capable of mounting multiple cores 60, a spindle mechanism 30 for driving the jig 20 to rotate so as to wind the cores 60 on the jig 20, a reversing mechanism 40 for driving the jig 20 to flip an angle so as to wind different cores 60, and a wire clamping mechanism 50 for clamping the end of a wire 70 when winding the core 60, wherein:

[0033] The spindle mechanism 30 includes a winding shaft 31, a spindle motor 32 and a pulley group 33. The winding shaft 31 is rotatably mounted on the bracket 10. The spindle motor 32 is also mounted on the bracket 10 and is connected to the winding shaft 31 through the pulley group 33. The pulley group 33 includes a driving pulley, a driven pulley and a transmission belt. The driving pulley is mounted on the shaft end of the spindle motor 32, the driven pulley is mounted on the winding shaft 31, and the transmission belt is sleeved on the driving pulley and the driven pulley.

[0034] The reversing mechanism 40 includes a reversing motor 41, a reversing rod 42, a connecting rod assembly 43, and a positioning assembly 44 for angular positioning of the fixture 20. The reversing motor 41 is mounted on the bracket 10, the reversing rod 42 is connected to the output end of the reversing motor 41, and the connecting rod assembly 43 is connected between the reversing rod 42 and the fixture 20.

[0035] The reversing mechanism 40 also includes a ball screw 45 and a slide 46. The shaft end of the reversing motor 41 is connected to the end of the ball screw 45. The slide 46 cooperates with the ball screw 45 and can be vertically slidably installed on the bracket 10. The reversing motor 41 drives the ball screw 45 to rotate, and the ball screw 45 drives the slide 46 to slide vertically on the bracket 10. The reversing rod 42 is connected to the slide 46.

[0036] The positioning assembly 44 includes a positioning rod 441, which is detachably inserted into the jig 20. The positioning assembly 44 also includes a positioning cylinder 442, which is connected to the shaft end of the positioning cylinder 442. The positioning rod 441 is driven by the positioning cylinder 442 to limit the position of the jig 20. The positioning rod 441 is vertically slidable through the reversing rod 42, which acts as a sleeve and slides outside the positioning rod 441, without interfering with each other's movements. Furthermore, the reversing rod 42 and the positioning rod 441 are both vertically inserted into the winding shaft 31, with three axes arranged coaxially, resulting in a high degree of integration and reduced space consumption.

[0037] The jig 20 can be installed in a flip-over manner relative to the winding shaft 31 on the top of the winding shaft 31; specifically, a fixed seat 311 is hingedly installed on the top of the winding shaft 31, and the jig 20 is detachably installed on the upper surface of the fixed seat 311 (after the winding is completed, the jig 20 and the iron core 60 will be removed from the fixed seat 311 together), and a connecting portion 312 is provided on the lower surface of the fixed seat 311; the connecting rod assembly 43 includes a first connecting rod 431 and a second connecting rod 432, the first connecting rod 431 is connected to the top of the reversing rod 42, and the second connecting rod 432 is hinged between the first connecting rod 431 and the connecting portion 312. The jig 20 is arc-shaped to accommodate the distribution direction of the stator cores 60 when the stator cores 60 are arranged in a circle. Two mounting slots 21 are provided on the upper surface of the jig 20 at intervals, and the cores 60 are detachably installed in the two mounting slots 21. The motor stator requires twelve cores 60 to be assembled, divided into three phases, and each phase has four cores 60. Two cores 60 form a group and are connected to each other by a transition line. The two mounting slots 21 are provided on the jig 20 precisely for winding a group (two) of cores 60 (the two cores 60 are wound separately, and a transition line connecting each other is formed after the winding is completed). A positioning slot 313 is provided on the lower surface of the fixing seat 311 in the direction corresponding to the two mounting slots 21, and a positioning slot 313 is further provided between the two positioning slots 313. The positioning rod 441 is detachably embedded in the positioning slot 313 under the drive of the positioning cylinder 442. The cooperation between the positioning rod 441 and the positioning slot 313 effectively fixes the angle of the jig 20, avoiding the angle deviation of the jig 20 caused by large torque during winding; the positioning slot 313 located in the middle keeps the jig 20 in a centrally symmetrical state when no winding is taking place.

[0038] The wire clamping mechanism 50 is located on the side of the fixture 20, and has a rotatable wire clamping assembly 51; the wire clamping mechanism 50 also includes a wire clamping seat 52 and a clamping device 53, the wire clamping seat 52 is installed on the side wall of the winding shaft 31, and a accommodating cavity 521 is provided at the upper end of the wire clamping seat 52, and the wire clamping assembly 51 is rotatably installed in the accommodating cavity 521 through a bearing; if the wire clamping assembly 51 is a fixed and non-rotatable form, then when the iron core 60 is wound, a U-shaped excess wire 70 will be generated between the end of the wire clamping assembly 51 and the iron core 60 as the iron core 60 rotates; and the wire clamping assembly 51 is designed to be rotatable, and the wire clamping assembly 51 rotates flexibly as the wire 70 twists when the iron core 60 is wound, which can avoid the generation of excess wire 70 during winding, thereby avoiding the action of cutting off the excess wire 70, simplifying the production process, and saving materials at the same time.

[0039] The wire clamping assembly 51 includes two wire clamping blocks 511 and a spring 512. The upper ends of the two wire clamping blocks 511 are hinged by a rotating shaft. The spring 512 abuts against the lower ends of the two wire clamping blocks 511, and the lower ends of the two wire clamping blocks 511 have a wedge-shaped matching portion 513; the elastic force generated by the spring 512 causes the lower ends of the two wire clamping blocks 511 to be stretched open, thereby keeping the upper ends of the two wire clamping blocks 511 in a normally closed state.

[0040] The clamping device 53 includes a pushing block 531 and a pushing cylinder 532 installed below the pushing block 531. The pushing block 531 can be slidably installed up and down on the lower end of the wire clamping seat 52. A wedge-shaped matching groove 533 that is compatible with the wedge-shaped matching part 513 is recessed at the upper end of the pushing block 531. When the pushing cylinder 532 pushes the pushing block 531 upward, the lower ends of the two wire clamping blocks 511 overcome the elastic force of the spring 512 and move closer to each other under the drive of the wedge-shaped matching part 513 and the wedge-shaped matching groove 533, thereby separating the upper ends of the two wire clamping blocks 511 from each other to achieve clamping. A pushing portion extends downward from the bottom of the pushing block 531, and a roller 534 is mounted on the pushing portion. The pushing cylinder 532 is mounted on the bracket 10, and a pushing plate 535 is mounted on the axial end of the pushing cylinder 532. A matching groove 536 is provided on the pushing plate 535 corresponding to the roller 534. The roller 534 and the matching groove 536 can be detachably abutted. The matching groove 536 is formed by the intersection of two opposing inclined surfaces, and the roller 534 cooperates with it. On the one hand, it can reduce frictional resistance, and on the other hand, due to the large lateral width of the matching groove 536, it can enable the roller 534 to quickly and effectively contact the pushing plate 535.

[0041] At least one magnet 54 is respectively provided on the outer wall of the two wire clamping blocks 511. In this embodiment, the two wire clamping blocks 511 are respectively semicircular and are put together to form a circle after being folded together; a wire clamping groove 514 is formed between the upper ends of the two wire clamping blocks 511, and trumpet-shaped openings 515 for facilitating threading are respectively provided at both ends of the wire clamping groove 514, and the wire 70 enters the wire clamping groove 514 through the opening 515. In this embodiment, three magnets 54 are embedded at intervals on the circumferential outer walls of the two clamping blocks 511 away from the clamping direction, and each magnet 54 is arranged radially; magnets 54 are also provided on the upper end of the clamping seat 52 corresponding to the magnets 54 on the two clamping blocks 511, and the magnets 54 on the clamping seat 52 and the magnets 54 on the clamping block 511 adsorb each other to ensure that the clamping groove 514 between the two clamping blocks 511 always corresponds to the winding groove of the iron core 60, thereby avoiding correction of the clamping assembly 51 before winding; the specific principle is that the three magnets 54 on each clamping block 511 can be adsorbed one-to-one with the three magnets 54 on one side of the clamping seat 52 or one-to-one with the three magnets 54 on the other side. In short, no matter how the two clamping blocks 511 rotate, the clamping groove 514 will always correspond to the winding groove of the iron core 60 to be wound on the jig 20 under the adsorption action of the magnet 54.

[0042] The operating method of the winding spindle includes the following steps:

[0043] S1. Under normal conditions, the middle portion of the jig 20 corresponds to the clamping mechanism 50. During winding, the reversing motor 41 drives the reversing rod 42 to move, and the connecting rod assembly 43 links the jig 20 to flip so that the iron core 60 to be wound corresponds to the clamping mechanism 50. The positioning assembly 44 positions the jig 20.

[0044] S2, the wire clamping assembly 51 is opened, and after the wire 70 enters the wire clamping assembly 51, the wire clamping assembly 51 clamps the wire 70;

[0045] S3, the spindle motor 32 drives the winding shaft 31 to rotate through the pulley assembly 33, and the fixture 20 and the wire clamping seat 52 rotate accordingly. The wire clamping assembly 51 rotates flexibly with the winding, and the wire 70 is wound in the winding groove of the iron core 60;

[0046] S4. After the winding of one core 60 is completed, the reversing motor 41 drives the reversing rod 42 to flip the fixture 20, and the other core 60 to be wound is aligned with the clamping mechanism 50, and the above winding action is repeated;

[0047] S5. After all the cores 60 on a jig 20 are wound, the jig 20 is removed and placed in an assembly station to proceed to the next process.

[0048] The design focus of the present invention is to form a winding spindle for the motor core by integrating the jig, spindle mechanism, reversing mechanism and wire clamping mechanism on the bracket. The winding spindle can wind multiple cores separately, automatically adjust the winding objects, and complete the winding operation of the transition wires between the cores. Compared with the traditional winding spindle that only winds one core at a time and the winding needle nozzle needs to adjust the angle continuously according to the position of the core, the winding spindle in this application can wind two cores in a group separately and wind the transition wires, without the need to set the needle nozzle and its angle adjustment mechanism, thereby simplifying the winding process, reducing the parts used in the winding mechanism, improving the winding efficiency and reducing the production cost.

[0049] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
