[0033] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0034] This application discloses a feeding mechanism for assembling a winding machine.

[0035] A feeding mechanism for an assembly winding machine includes a worktable 1, a turntable 2, a lower insulating sleeve placement assembly 3, a stator core placement assembly 4, an upper insulating sleeve placement assembly 5, and a spacing extension assembly 6. The worktable 1 is fixed to the ground, and the turntable 2 is horizontally positioned above it, driven to rotate around its own axis by a first power source 22. Several placement seats 21 are circumferentially arranged on the top of the turntable 2 along its axis. The lower insulating sleeve placement assembly 3, the stator core placement assembly 4, and the upper insulating sleeve placement assembly 5 are sequentially distributed circumferentially along their axes. The spacing extension assembly 6 is located near the placement seats 21 for easy operation.

[0036] In this embodiment, the first power source 22 is a drive motor, and the motor shaft is connected to the turntable 2 for transmission, thereby enabling the turntable 2 to rotate. When the upper insulating sleeve 82 and the lower insulating sleeve 81 are fitted onto the iron core, the lower insulating sleeve 81 is first placed on the placement seat 21 by the lower insulating sleeve placement assembly 3. Then, the turntable 2 moves the placement seat 21, which contains the lower insulating sleeve 81, to a position close to the stator core placement assembly 4. Before placing the stator core 8, the expansion assembly 6 expands the lower insulating sleeve 81 to allow partial insertion of the stator core 8. After the stator core placement assembly 4 partially inserts the stator core 8 into the lower insulating sleeve 81, the expansion assembly 6 withdraws, completing the full insertion of the stator core 8.

[0037] Next, turntable 2 moves the stator core 8 and lower insulating sleeve 81 to the position of upper insulating sleeve placement assembly 5. Upper insulating sleeve placement assembly 5 brings the upper insulating sleeve 82 closer to the stator core 8, and the spacing expansion assembly 6 further expands the upper insulating sleeve 82 for installation. After the upper insulating sleeve 82 is partially installed on the stator core 8, the spacing expansion assembly 6 is withdrawn, completing the installation of the upper insulating sleeve 82. Finally, turntable 2 moves the entire stator core 8, with the upper insulating sleeve 82 and lower insulating sleeve 81 installed, to the material removal position.

[0038] The lower insulating sleeve placement assembly 3 consists of a conveying section 31, a pickup and flipping section 32, and a pickup and placement section 33. The conveying section 31 includes a conveying rod 311 and a limiting member 312. The lower insulating sleeve 81 is slidably engaged with the conveying rod 311 and is moved along the length of the conveying rod 311 by a second power source 313. In this embodiment, the second power source 313 is a vibratory feeder, which drives the lower insulating sleeve 81 to move through vibration. To facilitate the movement of the lower insulating sleeve 81 toward the placement seat 21, the end of the conveying rod 311 near the placement seat 21 is designed to be inclined downwards.

[0039] The limiting component 312 consists of a limiting frame 3121 and a limiting plate 3122. The limiting frame 3121 is installed near the worktable 1, and the limiting plate 3122 is fixed on the limiting frame 3121 and located above the conveying rod 311. The limiting plate 3122 is aligned with the length of the conveying rod 311 and forms a limiting area with the conveying rod 311. During the conveying of the lower insulating sleeve 81, the limiting plate 3122 limits the lower insulating sleeve 81, reducing the possibility of it overturning, tipping over, or detaching from the conveying rod 311.

[0040] The pick-up and flipping unit 32 includes a lower insulating sleeve 81 and a first pick-up clamp 321, the position and angle of which are adjusted by a third power source 322. The third power source 322 includes a telescopic cylinder and a rotary cylinder. The telescopic cylinder is fixed on the worktable 1, and the rotary cylinder is fixed to the end of the push rod of the telescopic cylinder. The first pick-up clamp 321 is mounted on the rotary cylinder. After the insulating sleeve 81 is removed by the first pick-up clamp 321, the rotary cylinder flips it so that the stator core 8 insertion port faces upward.

[0041] The pickup and placement unit 33 includes a second pickup clamp 331, which uses a fourth power source 332 to place the lower insulating sleeve 81 onto the placement base 21. The fourth power source 332 includes a lateral drive unit 3321 and a longitudinal drive unit 3322. The lateral drive unit 3321 is mounted on the worktable 1, and the longitudinal drive unit 3322 is mounted on the lateral drive unit 3321. The second pickup clamp 331 is mounted on the longitudinal drive unit 3322. In this embodiment, both the lateral drive unit 3321 and the longitudinal drive unit 3322 are lead screw modules. The second pickup clamp 331, the lateral drive unit 3321, and the longitudinal drive unit 3322 cooperate to transfer the lower insulating sleeve 81 from the first pickup clamp 321 to the placement base 21.

[0042] The top of the placement base 21 is provided with a placement groove 211 for inserting the lower insulating sleeve 81, and the inner wall of the groove is provided with an opening for inserting the spacing expansion assembly 6. There are two spacing expansion assemblies 6, located in the stator core placement assembly 4 and the upper insulating sleeve placement assembly 5, respectively, so as to expand the spacing of the lower insulating sleeve 81 when the stator core 8 is placed on the lower insulating sleeve 81, and to expand the spacing of the upper insulating sleeve 82 before the upper insulating sleeve 82 is fitted onto the stator core 8.

[0043] A fixed disk 7 is horizontally positioned above the turntable 2. A fixed shaft is located at the bottom of the fixed disk 7, passing through the turntable 2 and rotating in conjunction with it. The spacing extension assembly 6 includes two spacing extension sections 61, arranged opposite each other. One section is mounted on the fixed disk 7, and the other is mounted on the stator core placement assembly 4 or the upper insulating sleeve placement assembly 5. By simultaneously extending the spacing of the lower insulating sleeve 81 or the upper insulating sleeve 82 using the two spacing extension sections 61, the stability of the upper insulating sleeve 82 and the lower insulating sleeve 81 during the spacing extension process is improved, reducing the possibility of tilting due to uneven force.

[0044] Each expansion section 61 includes an expansion plate 611, with an upper insulating sleeve 82 and a lower insulating sleeve 81 interlocking with the expansion plate 611. A guide plate 612 is integrally formed on the expansion plate 611. The width of the guide plate 612 gradually decreases from near to far from the expansion plate 611, with a minimum width less than the initial distance between the upper insulating sleeve 82 and the lower insulating sleeve 81. The expansion plate 611 moves towards or away from the placement seat 21 via a fifth power source 613. In this embodiment, the fifth power source 613 is a cylinder, and the expansion plate 611 is mounted on the end of the cylinder push rod, moving the expansion plate 611 via the cylinder push rod.

[0045] The stator core placement assembly 4 includes a tray 41 and a third pick-up clamp 42. The stator core 8 to be processed is placed on the tray 41, and the third pick-up clamp 42 uses a sixth power source 43 to pick up the stator core 8 from the tray 41 and place it onto the placement seat 21. In this embodiment, the sixth power source 43 is similar to the fourth power source 332.

[0046] The upper insulating sleeve placement assembly 5 has a similar structure to the lower insulating sleeve placement assembly 3. The upper insulating sleeve 82 is placed on the stator core 8 through the upper insulating sleeve placement assembly 5. The difference between the upper insulating sleeve placement assembly 5 and the lower insulating sleeve placement assembly 3 is that the upper insulating sleeve placement assembly 5 omits the pickup flipping part 32 of the lower insulating sleeve placement assembly 3, because the upper insulating sleeve 82 can be placed without flipping.

[0047] The implementation principle of the feeding mechanism for an assembly winding machine according to an embodiment of this application is as follows: First, the lower insulating sleeve 81 is moved along the conveying rod 311 to the placement seat 21 by the conveying part 31 in the lower insulating sleeve placement assembly 3 driven by the vibrating plate. Next, the turntable 2 drives the placement seat 21 to move to the vicinity of the stator core placement assembly 4, and the expansion assembly 6 opens the lower insulating sleeve 81 so that the stator core 8 can be partially inserted. The stator core placement assembly 4 uses the third picking clamp 42 to pick up the stator core 8 and place it on the placement seat 21. Then, the expansion assembly 6 is withdrawn, completing the insertion of the stator core 8. Then, the turntable 2 moves again, moving the stator core 8 and the lower insulating sleeve 81 to the position of the upper insulating sleeve placement assembly 5. The expansion assembly 6 opens the upper insulating sleeve 82. After the upper insulating sleeve 82 is partially fitted onto the stator core 8, the expansion assembly 6 is withdrawn, completing the fitting of the upper insulating sleeve 82. Finally, turntable 2 moves the stator core 8, fitted with the upper insulating sleeve 82 and the lower insulating sleeve 81, to the material handling position, completing the entire loading process. This process, through precise power source control and component coordination, achieves automated and efficient assembly of the stator core 8 and the insulating sleeve.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
