Description

Technical Field

[0001] This utility model relates to the field of automated motor production technology, and in particular to a modular stator winding device. Background Technology

[0002] In the field of motor manufacturing, the precision and efficiency of stator winding are key factors determining motor performance and manufacturing costs. Traditional integral stator core winding processes are complex and have low slot fill factor. To overcome this bottleneck, modular stator structures have emerged, dividing the core into independent modules. Each module can be wound individually before assembly. This modular design significantly improves the spatial accessibility and flexibility of winding operations, reducing operational difficulty compared to integral stators. However, the advantages of modular structures also bring new challenges. Each module must achieve extremely high positioning accuracy during winding to ensure the symmetry of the windings in each module. Existing winding machines typically wind each module independently, making it difficult to control the consistency of the number of turns, tension, and span of the coils on each module.

[0011] Furthermore, the winding fixture includes a fixture body and side baffles on both sides.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0021] One embodiment of this utility model provides a modular stator winding device, such as... Figure 1 The diagram shown is a structural schematic of the modular stator winding device in this embodiment. In this embodiment, the modular stator winding device includes: a workbench 1, a base 2 installed in the middle of the workbench 1, and several rotating spindles 21 mounted side-by-side on the base 2, as shown... Figure 2 The diagram shows the installation of the rotating spindle in this embodiment. A winding fixture 22 for horizontal support and positioning of the modular stator 3 is mounted on the top of the rotating spindle 21. A drive motor 23 is connected to the bottom of the rotating spindle 21. A gantry-type pressing assembly 4 is mounted above the base 2. The pressing assembly 4 includes a pressing beam 41 that can be raised and lowered as a whole, and several pressing rod assemblies 42 rotatably mounted on the pressing beam 41. The position and number of the pressing rod assemblies 42 correspond one-to-one with the rotating spindle 21. When the pressing assembly 4 descends, each pressing rod assembly 42 presses and fixes the modular stator 3 to the corresponding winding fixture 22, making the modular stator 3 rigidly connected to the rotating spindle 21 and rotating synchronously. A three-axis moving mechanism 5 is provided on one side of the base 2. Several winding nozzle units 51, each corresponding to one of the winding fixtures 22, are provided on the moving end of the three-axis moving mechanism 5. The three-axis moving mechanism 5 drives the winding nozzle units 51 to move according to a preset trajectory, completing the parallel winding operation of multiple modular stators 3.

[0022] The base 2 can be a strip-shaped structure. The rotating spindle 21 is mounted side-by-side on the base 2 via bearings, providing a foundation for the synchronous winding of multiple modular stators 3. The winding fixture 22 is used to horizontally support the modular stators 3, enabling them to complete the winding operation as they rotate with the rotating spindle 21. The winding fixture 22 can have specific positioning structures, such as pins or slots, to ensure that the modular stators 3 can be accurately and repeatedly placed in the correct position and angle each time. The gantry-type pressing assembly 4 can improve the stability of the pressing and has a large coverage area, ensuring that each modular stator 3 can be effectively pressed, avoiding winding errors caused by differences in workpiece height. The winding nozzle unit 51 can be connected to the moving end of the three-axis moving mechanism 5 via a horizontally set mounting plate 52, including a wire and a tension control structure, and can independently realize winding work. This utility model, through the coordinated design of the rotating spindle 21, the pressing component 4, and the three-axis moving mechanism 5 arranged side by side, not only enables mass production and improves production speed, but also ensures winding accuracy, significantly improves production efficiency and product consistency, reduces reliance on manual labor and costs, and meets the winding requirements of modern motor industry for modular stator 3.

[0023] Figure 3 This is a schematic diagram of the dual-track conveying mechanism in this embodiment, as shown below. Figure 1 and Figure 3 As shown, a dual-rail conveying mechanism 6 is provided on the other side of the base 2, including two parallel reciprocating conveying tracks 61, which are used to convey the block stator 3 before and after winding respectively; a three-axis feeding assembly 7 is mounted above the reciprocating conveying tracks 61, and a moving plate is provided at the moving end of the three-axis feeding assembly, and a suction cup array is arranged side by side. The layout of the suction cup array matches the winding fixture 22.

[0024] Two reciprocating conveyor tracks 61 transport unwound stator blocks 3 and wound stator blocks 3 respectively, physically isolating the inlet and outlet, simplifying logistics management, avoiding misplacement, and allowing for continuous and independent supply of raw materials and shipment of finished products, thus improving operational efficiency. The number of suction cups in the suction cup array corresponds to the rotating spindle 21, and the moving plate of the three-axis loading assembly 7 completes the loading and unloading operations of multiple stator blocks 3 at once, improving production efficiency.

[0025] like Figure 3 As shown, the reciprocating conveyor track 61 is a belt conveyor mechanism. A conveyor plate 62 is fixed on the belt of the belt conveyor mechanism. Several conveyor fixtures 63 are fixedly installed on the conveyor plate 62. The number and position of the conveyor fixtures 63 correspond one-to-one with the winding fixtures 22. The conveyor fixtures 63 are provided with positioning and clamping structures.

[0026] The belt conveyor mechanism and conveyor plate 62 determine the position of each assembly stator 3, improving conveying accuracy. During the loading process, the three-axis loading assembly 7 does not need to repeatedly position the assembly stator 3, thus improving processing efficiency. The number and position of the conveying fixtures 63 correspond one-to-one with the winding fixtures 22, enabling the three-axis loading assembly 7 to complete loading and unloading operations in one go, further improving efficiency. The positioning and clamping structure of the conveying fixtures 63 can be any structure that improves the positioning accuracy of the assembly stator 3, preventing the assembly stator 3 from shaking during conveying. The positioning and clamping structure can be self-unlocking or can be equipped with other unlocking mechanisms, unlocking at the gripping position of the three-axis loading assembly 7. A fixing mechanism for fixing the conveyor plate 62 is provided on the reciprocating conveyor track 61. When the conveyor plate 62 moves to the preset position, it is positioned and fixed by a sensor, further improving positioning accuracy.

[0027] like Figure 4 The diagram shows the structure of the conveying fixture in this embodiment. The conveying fixture 63 includes a main body 631, whose top surface is provided with a limiting groove 632 that matches the contour of the assembly stator 3, and a through hole is provided along the conveying direction perpendicular to the belt. A movable bidirectional linkage shaft 633 is sleeved in the through hole. Both ends of the bidirectional linkage shaft 633 extend out of the main body 631. One end is connected to a movable locking block 634, and the other end is connected to an unlocking stop block 635. A fixed locking block 636 symmetrical to the movable locking block 634 is fixedly installed on the main body 631. Both the fixed locking block 636 and the movable locking block 634 are higher than the limiting groove 632 and are used to clamp the assembly stator 3. A thrust spring 637 is provided between the unlocking stop block 635 and the fixed locking block 636 so that the movable locking block 634 remains close to the main body 631 in the normal state.

[0028] In this embodiment, the stator 3 is automatically positioned in the limiting groove 632 by its own weight, and the two sides of the stator 3 are squeezed and clamped by the movable locking block 634, which improves the positioning accuracy and transportation stability. The height of the fixed locking block 636 and the movable locking block 634 can be set low, preferably clamping the magnetic core part of the stator 3 to prevent damage to the enameled wire.

[0029] like Figure 3 As shown, in this embodiment, a fixture unlocking mechanism 64 is also included. The fixture unlocking mechanism 64 includes a bracket parallel to the conveying direction of the belt and several cylinders mounted on the bracket. The moving end of the cylinder faces the unlocking stop 635 to overcome the elastic force of the thrust spring 637, so that the movable locking block 634 is separated from the main body part 631 and the stator block 3 is unlocked.

[0030] The moving end of the cylinder can be equipped with a push plate, which allows one cylinder to unlock two or more conveying fixtures 63 at the same time, saving costs.

[0031] like Figure 5 The diagram shows the structure of the winding nozzle unit in this embodiment. The winding nozzle unit 51 is mounted on the mounting plate 52, which is parallel to the base 2. The mounting plate 52 is fixedly mounted on the moving end of the three-axis moving mechanism 5. The number and position of the winding nozzle units 51 correspond one-to-one with the winding fixture 22. The diagram also includes a wire frame assembly for supplying wire to the winding nozzle unit 51. Several tensioners and wire spools corresponding one-to-one with the winding nozzle unit 51 are arranged side by side on the wire frame assembly.

[0032] The mounting plate 52 is horizontally positioned to stably support the winding nozzle unit 51, thereby improving the stability of the winding. A vertical plate can be installed on the side of the mounting plate 52 facing the winding fixture 22 to facilitate the installation of components such as the outlet nozzle. The vertical plate is also parallel to the base 2.

[0033] like Figure 1 and Figure 5 As shown, in this embodiment, a wire cutting mechanism 8 is also included. The wire cutting mechanism 8 includes an inclined fixing plate 81 disposed above the mounting plate 52, an inclined sliding plate 82 slidably mounted on the inclined fixing plate 81, and a drive electric cylinder 83 for driving the inclined sliding plate 82 to move. Several pneumatic cutters 84 corresponding one-to-one with the winding nozzle unit 51 are installed on the inclined sliding plate 82. The pneumatic cutters 84 are used to move with the inclined sliding plate 82 to the wire cutting position at the front end of the winding nozzle unit 51.

[0034] The inclined slide plate 82 is mounted on the inclined fixing plate 81 via a sliding rail. The inclined fixing plate 81 is inclined toward the end of the wire outlet of the winding nozzle unit 51, so that the pneumatic cutting pliers 84 can move downward at an angle and move to the position of the wire outlet, thereby cutting the enameled wire.

[0035] like Figure 6 The diagram shown is a schematic diagram of the winding fixture in this embodiment. The winding fixture 22 includes a fixture body 221 and side baffles 222 on both sides. The top surface of the fixture body 221 is a contour positioning surface 223, which is used to fit the outer peripheral surface of the assembly stator 3. The bottom of the fixture body 221 is provided with a mounting shaft 224 coaxial with the center line of the fixture body 221. The top of the rotating spindle 21 is provided with a mounting hole. The mounting shaft 224 is fitted into the mounting hole and fixed with a pin.

[0036] The contour positioning surface 223 is contoured to the outer circumferential surface of the modular stator 3, specifically in the form of a groove. The side baffle 222 is used to limit the movement along the axis of the modular stator 3. The mounting shaft 224 is coaxial with the center line of the fixture body 221, which can improve the stability of the modular stator 3 during rotation. The connection through the shaft hole further improves the positioning accuracy and coaxiality.

[0037] like Figure 7The diagram shows the structure of the pressure rod assembly in this embodiment. The pressure rod assembly 42 includes a pressure rod sleeve 421 mounted on the lower pressure beam 41 via bearings, and a pressure rod body 422 sleeved in the pressure rod sleeve 421. A strip-shaped limiting hole 423 is provided axially on the wall of the pressure rod sleeve 421, and a movable shaft pin 424 for sliding in the strip-shaped limiting hole 423 is fixedly installed on the pressure rod body 422. A pressure rod spring 425 is provided between the pressure rod sleeve 421 and the pressure rod body 422, and the pressure rod spring 425 acts on the pressure rod body 422 to provide it with a downward elastic force. A lower pressure head 426 with a circular arc surface is installed at the bottom of the pressure rod body 422, and the lower pressure head 426 is used to fit and press the inner circumferential surface of the splice block stator 3.

[0038] In this embodiment, the pressure rod sleeve 421 provides elastic clamping force to the pressure rod body 422, and the length of the strip-shaped limiting hole 423 limits the axial sliding stroke of the pressure rod body 422 relative to the pressure rod sleeve 421. A stepped hole can be provided on the inner side of the pressure rod sleeve 421, and a collar can be provided at the corresponding position on the pressure rod body 422. The pressure rod spring 425 can be installed between the stepped hole and the collar. The lowering beam 41 can be driven to press down by a cylinder. The lowering head 426 first contacts the inner circumferential surface of the block stator 3. The lowering beam 41 drives the pressure rod sleeve 421 to continue to move down. The pressure rod sleeve 421 applies pressure to the pressure rod spring 425, so that the pressure rod body 422 further presses the block stator 3 and gradually increases the pressure on the block stator 3. The rigid thrust of the cylinder is converted into controllable elastic pressure, avoiding instantaneous rigid collision damage to the block stator 3. In this embodiment, the pressure received by the block stator 3 is evenly distributed, which can prevent local overpressure from causing the block stator 3 to misalign or move and fall.

[0039] In this embodiment, an annular positioning disk 43 is also installed on the lower pressure beam 41. The annular positioning disk 43 is provided with a central hole for accommodating the pressure rod body 422 to pass through, and a positioning groove 431 that passes through the center laterally is provided on its upper surface. A positioning rod 427 that cooperates with the positioning groove 431 is installed on the upper end of the pressure rod body 422.

[0040] The positioning groove 431 is located on the surface of the annular positioning disk 43. The shape of the positioning groove 431 matches the shape of the positioning rod 427, allowing them to fit precisely and achieve angle positioning. In use, first, ensure the positioning rod 427 is in the positioning groove 431. Then, activate the downward-pushing cylinder to drive the downward-pressing assembly 4 to descend. During descent, the downward-pressing head 426 contacts the inner circumferential surface of the stator 3, and the pressure rod spring 425 begins to compress, providing elastic clamping force to precisely lock the angle of the pressure rod body 422. The annular positioning disk 43 continues to move downward with the mounting plate 52, causing the positioning rod 427 to disengage from the positioning groove 431. At this time, the rotating spindle 21 can drive the entire fixture to rotate for winding, while the annular positioning disk 43 remains stationary, not affecting the rotation of the pressure rod body 422. This embodiment achieves high-precision angle positioning through a mechanical groove-locking structure, ensuring high positioning accuracy, low cost, and stable and reliable operation.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
