Description

Technical Field

[0001] This invention relates to the field of stator manufacturing technology, and in particular to an integrated paper-making and wire-inserting device for slender stators. Background Technology

[0002] The stator is the stationary part of an electric motor or generator. It mainly consists of a stator core and coils wound around the stator core. In the stator manufacturing production line, the stator needs to go through processes such as paper insertion, winding, coil embedding, shaping, and coil binding.

[0003] In existing technologies, automatic winding molds with a release mechanism are generally used for winding. For example, in existing technology CN208608870U, the movable winding mold used is a release-type winding mold. However, for relatively slender stators, such as stators with an inner diameter of no more than 40 mm, the winding mold is too small, resulting in an even smaller diameter of the axial parts of the release-type winding mold, and its strength is completely insufficient for the work requirements. Therefore, it is necessary to develop an integrated paper-pressing and winding device for slender stators, which must meet the customer's requirements for multi-station speed improvement, ensure that the paper-pressing material magazine and the winding mold do not interfere with each other, and also meet the space requirements of the equipment. Summary of the Invention

The positioning cover has a positioning groove that mates with the positioning block. When the positioning block is inserted into the positioning groove, the positioning rod locks the pinion through the release mechanism. When the lifting rod is driven upward by the lifting component and connects with the positioning rod, it triggers the release mechanism, releasing the positioning rod from locking the pinion.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] like Figure 1-9As shown, a paper-pressing and wire-embedding integrated device with a slender stator includes a frame 1 and a rotary table 2 located inside the frame 1. The frame 1 is equipped with a protective outer frame for good safety. A control box for the control equipment is also located on one side of the frame 1. One side of the rotary table 2 is a paper-pressing station, and the other side is a wire-embedding station. Wire-embedding molds 3 are provided on both sides of the rotary table 2 corresponding to the paper-pressing and wire-embedding stations. A paper material magazine 31 integrated with the wire-embedding molds 3 is located below the wire-embedding molds 3. The rotary table 2 is rotatably connected to the frame 1 through a drive mechanism 4, and can alternate between the paper-pressing and wire-embedding stations. The rotary table 2 is positioned at the paper-pressing station... A paper-feeding module 100 connected to the paper stock 31 is also provided on one side of the paper station. The paper-feeding module 100 includes a paper-feeding mechanism 5, a pushing mechanism 6, and an indexing mechanism 7 movably connected to the wire-inserting mold 3. The paper-feeding mechanism 5 is used to feed the slot cover paper into the paper stock 31. The pushing mechanism 6 is used to push the paper-feeding mechanism 5 to connect with the paper stock 31. The indexing mechanism 7 is used to drive the paper stock 31 to rotate in an indexing manner. A wire-inserting module 200 is provided on one side of the rotating table 2 at the wire-inserting station. The wire-inserting mold 200 is used to push the slot cover paper in the paper stock 31 and the wire on the wire-inserting mold 3 into the stator. In this embodiment, the stator is a small stator with an inner diameter of 23 and an outer diameter of 55, and the wire is inserted in three stages, corresponding to the three phases of the stator. During operation, firstly, at the paper-printing station, the paper-printing mechanism 5 starts to embed the slot cover paper into the corresponding slot of the paper material magazine 31. After printing paper into one slot, the indexing mechanism 7 drives the paper material magazine 31 to rotate by an angle until slot cover paper is embedded in all slots of a phase. At the same time, the manual wire hanging mechanism hangs the wire in the corresponding position on the wire-hanging mold 3. After one printing and wire hanging cycle is completed, the pushing mechanism 6 drives the paper-printing mechanism 5 to move backward, and then the driving mechanism 4 drives the rotary table 2 to rotate 180°. The wire-hanging mold 3, which completes the printing and wire hanging, rotates to the wire-hanging station, and then the wire-hanging module 200 completes the wire-hanging of one phase. After the wire-hanging is completed, the stator passes through... The robot and other feeding devices feed the material to the expansion machine for shaping. The unloaded wire embedding mold 3 waits for the rotary table 2 to alternate. At the same time, the wire embedding mold at the paper-cutting station continues to cut paper and hang wire until the three-phase wire embedding of one stator is completed. By integrating the wire embedding mold and the paper material library into one unit and fixing it on both sides of the rotary table, the paper-cutting station and the wire embedding station can alternate. It integrates paper cutting and wire embedding functions and can perform paper cutting and wire embedding at the same time. The structure is simple, saves equipment space and cost, realizes the multi-functional integration of equipment, meets the customer's need for multi-station improvement of work cycle, ensures high-speed operation of the production line, and effectively improves processing efficiency and processing quality.

[0031] In the above structure, such as Figure 7-9As shown, the paper-pressing module 100 also includes a support platform 11, which is fixed to the base of the frame 1 by a column. The paper-pressing mechanism 5 is mounted on the support platform 11 and includes a main board 51, a paper-pressing cylinder 52, and a connecting rod 53. The paper-pressing cylinder 52 is fixed to one end of the main board 51. The bottom end of the connecting rod 53 is hinged to the main board 51, and the upper end is connected to the telescopic end of the paper-pressing cylinder 52. The connecting rod 53 is driven by the paper-pressing cylinder 52 to rotate around its bottom end. A connecting arm 1 54 is connected to the top end of the connecting rod 53, and a connecting arm 2 55 is connected to the bottom end. The connecting arm 1 54 and the connecting arm 2 55 are arranged parallel to each other. The connecting arm 1 54 is connected to the paper-pressing slide 56, and the connecting arm 2 55 is connected to the paper-cutting slide 57. The paper-pressing slide 56 and the paper-cutting slide 57 are both horizontally connected to the main board 51. The paper-pressing slide 56 is connected to the paper-pressing knife 58, and the paper-cutting slide 57 is connected to the paper-cutting knife 59. Initially, the upper end of the connecting rod 53 is inclined towards the paper-pressing cylinder 52. When the paper-pressing cylinder 52 extends, it drives the connecting rod 53 to rotate, thereby driving the connecting arm 54 and the connecting arm 55 on the connecting rod 53 to rotate, thereby driving the paper-pressing slide 56 and the paper-cutting slide 57 to move, driving the paper-cutting knife 59 to complete the paper-cutting action and the paper-pressing knife 58 to complete the paper-pressing action. This connecting rod structure can realize the process of cutting paper first and then pressing paper. It can be seen that this paper-pressing mechanism has a simple structure, small size, and convenient installation. It can reduce costs while meeting production needs.

[0032] like Figure 7 , 9 As shown, the paper-pressing mechanism 5 also includes a paper-pressing mold, which includes a blade plate 510 and a paper-pressing blade holder 511 and a paper-cutting blade holder 512 disposed on the blade plate 510. The blade plate 510 is connected to the main plate 51. The paper-pressing blade holder 511 is disposed above the paper-cutting blade holder 512 and has a guide hole for guiding the movement of the paper-pressing blade 58. The paper-cutting blade holder 512 has a guide hole for guiding the movement of the paper-cutting blade 59. The guide holes improve the accuracy of paper cutting and pressing. The paper-pressing blade holder 511 has a forming groove, and the blade plate 510 has a through groove communicating with the forming groove. The through groove is connected to the slot cover paper embedding groove on the paper material magazine 31. During paper pressing, after the slot cover paper is pressed into the embedding groove, the paper magazine rotates at an angle, and the slot cover paper is pressed into the adjacent embedding groove.

[0033] Among them, such as Figure 3 , 7As shown in Figure 8, the pushing mechanism 6 includes a pushing component and a locking component. The pushing component includes a pushing cylinder 61, a connecting seat 62, and a slide rail 63. The pushing cylinder 61 is fixed on the support platform 11. The connecting seat 62 is located on the back of the main board 51 and is connected to the telescopic end of the pushing cylinder 61. The slide rail 63 is located at the bottom of the main board 51 and is slidably connected to the slider on the support platform 11. The pushing cylinder 61 pushes and the slide rail 63 guides, ensuring stable and smooth movement of the main board 51. In addition, a locking component is also provided on one side of the pushing cylinder 61. The device includes a buffer component to reduce the impact when the paper-printing die docks with the paper feed 31, minimizing damage to the equipment. The locking assembly includes a positioning cylinder 64, a positioning head 65, and a positioning seat 66. The positioning cylinder 64 is fixed above the support platform 11 via a cylinder seat. The telescopic end of the positioning cylinder 64 is connected to the positioning head 65. The back of the main board 51 has a positioning seat 66 movably connected to the positioning head 65. The positioning head 65, driven by the positioning cylinder 64, can be inserted into the positioning hole of the positioning seat 66, locking the position of the main board 51. The pushing assembly prevents interference between the paper-printing die 100 and the wire-embedding die 3 when the rotary table 2 rotates. Furthermore, when the pushing cylinder 61 extends, the paper-printing die docks with the paper feed 31, and then the positioning assembly locks the position of the main board 51, preventing paper-printing die displacement during printing and improving printing quality.

[0034] Example 2

[0035] Based on the structure of Example 1, such as Figure 4-5 As shown, the drive mechanism 4 includes a drive motor 41, a reduction gearbox 42, and a flange coupling 43. The reduction gearbox 42 is mounted on a support frame 44, which is fixed above the base of the frame 1. The reduction gearbox 42 is connected to the drive motor 41 and to the rotary table 2 via the flange coupling 43. A dividing sensor block 45 is also provided on the transmission shaft connecting the reduction gearbox 42 and the drive motor 41. A proximity switch that cooperates with the dividing sensor block 45 is provided on the support frame 44. The rotation position of the rotary table 2 is controlled by the dividing sensor block 45 and the proximity switch to ensure accurate docking of the paper-printing station and the wire-embedding station.

[0036] The paper-pressing and wire-inserting integrated device with a slender stator described in this invention also includes a pre-feeding mechanism 10, such as... Figure 2-3 As shown, the pre-feeding paper mechanism 10 includes a paper tray 101, a guide assembly 102, and a paper feeding assembly 103. The guide assembly 102 includes multiple guide members for guiding the paper from the paper tray 101 to the paper feeding assembly 103. The guide members include guide wheels, guide rods, etc. The paper feeding assembly 103 is used to transport the paper to the paper printing module 100.

[0037] Among them, such as Figure 4-6As shown, the indexing mechanism 7 includes a servo motor 71, a bearing housing 72, a bushing 73, an indexing shaft 74, a pinion 75, and an intermediate gear 76. The servo motor 71 is mounted on the support frame 44. The bushing 73 is connected to the output end of the servo motor 71 via a coupling. The bearing housing 72 is fitted outside the bushing 73, and the bearing housing 72 is connected to the support frame 44 via an adapter plate 77. The indexing shaft 74 is inserted into the bushing 73 and slidably connected to the bushing 73. The pinion 75 is mounted on the rotary table. On the 2nd, an active bearing seat 78 is fitted externally. The pinion 75 is rotatably connected to the rotary table 2 through the active bearing seat 78. The pinion 75 is connected to the indexing shaft 74 through a lifting assembly. The intermediate gear 76 meshes with the pinion 75. The active bearing seat 78 has an opening, and the part of the pinion 75 exposed outside the opening meshes with the intermediate gear 76. The intermediate gear 76 is rotatably connected to the rotary table 2 through a driven bearing seat 79. The insert mold 3 is provided with a large gear that meshes with the intermediate gear 76. When in the paper-printing state, the indexing shaft 74 and the pinion 75 are separated, and the pinion 75 does not rotate. When one paper-printing cycle is completed and the paper feed 31 needs to rotate, the lifting assembly drives the indexing shaft 74 to rise and connect with the pinion 75, realizing the connection between the pinion 75 and the servo motor 71. The servo motor 71 starts and drives the pinion 75, the intermediate gear 76, and the large gear to rotate by an angle, thereby realizing the indexing rotation of the paper feed 31.

[0038] In the above structure, the lifting assembly includes a lifting cylinder 710 and a lifting plate 711. The lifting cylinder 710 is fixed on the adapter plate 77, and the output end of the lifting cylinder 710 is connected to the lifting plate 711. The lifting plate 711 is connected to the indexing shaft 74 and is used to drive the indexing shaft 74 to rise and fall. The upper end of the pinion 75 is a tooth, and the lower end is a connecting bushing 751. The pinion 75 is rotatably connected to the rotary table 2 through the cooperation of the connecting bushing 751 and the drive bearing seat 78. The connecting bushing 751 is arranged vertically and vertically corresponding to the indexing shaft 74, and when the indexing shaft 74 rises, it engages with the connecting bushing 751 to realize the connection between the pinion 75 and the servo motor 71. Specifically, the indexing shaft 74 is provided with a locking block protruding from the shaft end, and the connecting bushing 751 is provided with a slot that cooperates with the locking block. The locking block is inserted into the slot, and the pinion 75 rotates with the indexing shaft 74. In addition, the indexing mechanism 7 also includes an origin sensor to control the rotation angle of the indexing shaft 74, ensuring that each rotation angle corresponds to the angle of a stator slot.

[0039] In addition, such as Figure 6As shown, the indexing mechanism 7 further includes a positioning assembly, which includes a lifting rod 712, a positioning rod 713, a positioning block 714, and a positioning cover 715. The lifting rod 712 is fixedly connected to the indexing shaft 74. The positioning cover 715 is fixed on the rotary table 2, located directly above the pinion 75. The positioning rod 713 is inserted into the pinion 75 and slidably connected to it. A release mechanism is also provided between the positioning rod 713 and the pinion 75. A positioning block 714 is connected to the top-mounted positioning cover 715. The positioning cover 715 has a positioning groove 7151 that mates with the positioning block 714. When the positioning block 714 is inserted into the positioning groove 7151, the positioning rod 713 locks the pinion 75 through a release mechanism. When the lifting rod 712 is driven to rise by the lifting assembly and connects with the positioning rod 713, it triggers the release mechanism, and the positioning block 714 also rises and disengages from the positioning groove 7151, releasing the locking of the positioning rod 713 to the pinion 75. Except when the indexing shaft 74 rises and connects with the pinion 75, the positioning block 714 is always inserted into the positioning groove 7151, and the positioning rod 713 locks the pinion 75. This arrangement can prevent the paper material magazine 31 and the winding mold 3 from shifting, ensuring accurate alignment between the winding mold 3 and the stator, thereby improving processing quality.

[0040] In addition, such as Figure 1-3 As shown, the winding module 200 includes a stator pressing mechanism 8 and an upward pushing mechanism 9. The upward pushing mechanism 9 cooperates with the stator pressing mechanism 8 to wind the wire. The stator pressing mechanism 8 is located on the upper end of the frame 1 and is used to press the stator onto the winding mold 3 and position the stator and the winding mold 3 at their docking positions.

[0041] The working method of the paper-punching and wire-inserting integrated device with a slender stator according to the present invention includes the following steps:

[0042] S1. The pre-feeding paper mechanism 10 guides the slot cover paper to the paper output mechanism;

[0043] S2. The push cylinder 61 starts to push the main board 51 closer to the paper material library. After it is in place, the positioning cylinder 64 pushes the positioning head 65 to insert into the positioning seat 66 and locks the position of the main board 51.

[0044] S3. The paper-feeding mechanism 5 starts to embed the slot cover paper into the corresponding embedding slot of the paper material library 31. After the paper is fed into one embedding slot, the indexing mechanism 7 drives the paper material library 31 to rotate by an angle until the slot cover paper is embedded in all the slots of one phase sequence of the paper material library. At the same time, the manual wire hanging mechanism hangs the wire on the corresponding position of one phase sequence on the wire embedding mold 3.

[0045] S4. After completing the paper-printing and wire-hanging of one phase sequence, the pushing mechanism 6 drives the paper-printing mechanism 5 to move backward, the driving mechanism 4 starts, and drives the rotary table 2 to rotate 180° to complete one alternation between the paper-printing station and the wire-hanging station.

[0046] S5. After completing the paper-printing and wire-hanging of a phase sequence, the wire-insertion mold 3 rotates to the wire-insertion station, starts the wire-insertion module, completes the wire-insertion of one phase, and after the wire-insertion is completed, the stator is fed into the expansion machine for shaping by the robot and other feeding devices.

[0047] S6. While the wire is being inserted, the wire insertion mold 3 at the paper-cutting station completes the paper-cutting and wire-hanging of the second phase. Then the drive mechanism 4 starts and drives the rotary table 2 to rotate 180°, completing another alternation between the paper-cutting station and the wire insertion station. This cycle continues until the wire insertion of the stator is completed.

[0048] The entire implementation process can be run continuously and is easy to operate, ensuring high-speed operation of the production line and effectively improving processing efficiency and quality.
