Description

Technical Field

[0001] This utility model belongs to the technical field of winding equipment, and in particular relates to a cyclic alternating multi-station external winding machine. Background Technology

[0002] Motor rotor winding machines are core equipment in motor production, responsible for precisely winding enameled wire into the rotor core slots. They are mainly divided into three categories: manual (flexible, low cost, suitable for small batches), semi-automatic (moderate efficiency and quality), and fully automatic (high efficiency, high precision, supporting complex processes). Among them, fully automatic winding machines integrate advanced loading and unloading systems to achieve continuous and efficient production. They often use multi-axis robotic arms, such as six-axis SCARA, gantry-type, or high-speed rotating indexing plates, to precisely grasp and transfer the rotor. The combination of vibratory discs and linear guides efficiently handles the sorting of small, standardized rotors. The feeding belt chain conveyor connects the upstream and downstream processes, while customized silos and pylons provide large-capacity storage to support unmanned operation. These automated loading and unloading solutions, combined with precise motion control, closed-loop tension systems, and visual positioning technology, ensure a high degree of consistency, excellent efficiency, and intelligent level in the winding process. Ultimately, a closed-loop automated production process is formed from automatic loading, precise winding, online detection, and automatic unloading. It continues to develop towards higher flexibility, such as 3D vision random grasping, intelligent interconnection, and deep integration. However, the existing structure used to implement motor rotor winding machine loading and unloading has technical problems such as loading and unloading pauses, which affect production efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0050] In one embodiment of this utility model, such as Figure 1 As shown, a multi-station winding machine with alternating cycles is provided, including a base 10, a rotary feeding device 20, a rotating device 30, a fixing device 40, and a winding device 50, wherein;

[0051] like Figure 1 As shown, the base 10 is used as an assembly base;

[0052] like Figure 2 As shown, at least one rotary feeding device 20 is provided. The rotary feeding device 20 includes a carrier plate 21, four rotary placement seats 22 and a rotary mechanism 23. The rotary mechanism 23 is mounted on the base 10. The rotating end of the rotary mechanism 23 is connected to the center of the bottom of the carrier plate 21. The carrier plate 21 has four first mounting holes 211. The four first mounting holes 211 are all arranged to penetrate the carrier plate 21 vertically. Each rotary placement seat 22 is rotatably mounted in each of the first mounting holes 211.

[0053] like Figure 3As shown, the rotating device 30 includes a rotary motor 31, a first lifting cylinder 32, a mounting plate 33, a positioning plate 34, and at least two connecting columns 35. The positioning plate 34 is mounted on the base 10 and has at least two second mounting holes 341. Each connecting column 35 is fitted with a radial sliding bearing, which is installed in each of the second mounting holes 341. The bottom of each connecting column 35 is rotatably connected to the mounting plate 33. Each connecting column 35 can be raised and lowered to engage with the bottom of each rotating placement seat 22 on the processing side. The rotary motor 31 and the first lifting cylinder 32 are both mounted on the mounting plate 33. The lifting end of the first lifting cylinder 32 is connected to the bottom of the positioning plate 34, and the rotating end of the rotary motor 31 is connected to the bottom conveyor belt of each connecting column 35.

[0054] like Figure 5 As shown, the fixing device 40 includes a lifting frame mechanism 41, a positioning mechanism 42, and two second lifting cylinders 43. The two support columns 411 of the lifting frame mechanism 41 are slidably connected to the base 10. The second lifting cylinders 43 are installed on the base 10, and the moving ends of the two second lifting cylinders 43 are respectively connected to the two support columns 411. The positioning mechanism 42 is installed on the lifting frame mechanism 41, and the positioning mechanism 42 is provided with a plurality of buffer column assemblies 423 whose bottoms are respectively corresponding to the bottoms of the rotating placement seats 22 on the processing side.

[0055] like Figure 8 As shown, the winding device 50 is mounted on the base 10, and the winding device 50 is provided with a plurality of winding ends, each winding end being arranged toward the rotor between each buffer column assembly 423 and each rotating placement seat 22.

[0056] During processing, the rotor is placed on a rotating placement seat 22 away from the processing side. The rotating mechanism 23 rotates the carrier plate 21, causing the rotating placement seat 22 with the rotor to rotate to the processing side. The second lifting cylinder 43 lowers the lifting frame mechanism 41, driving the positioning mechanism 42 to descend, so that each buffer column assembly 423 is aligned and engaged with the rotor placed on the rotating placement seat 22. The first lifting cylinder 32 drives the connecting column 35 to rise and engage with the bottom of the corresponding rotating placement seat 22. The rotating motor 31 rotates each connecting column 35, driving the rotating placement seat 22 to rotate. The winding device 50 winds the rotor on the rotating placement seat 22. At the same time, the rotating motor 31 rotates the rotor angle to complete the winding of the rotor. After the winding is completed, the connecting column 35 descends and disengages from the rotating placement seat 22. The above steps are repeated to switch rotating placement seats 22 to complete the cycle operation. Through the above structural settings, uninterrupted feeding is achieved to complete the winding, improving efficiency.

[0057] In another embodiment of this utility model, such as Figure 2As shown, a limit pin 221 is provided at the bottom of the rotating placement base 22.

After engagement, the connecting column 35 rotates, which drives the rotating placement base 22 to rotate.

[0058] In another embodiment of this utility model, such as Figure 2 and Figure 9 As shown, the bottom of the carrier plate 21 is provided with two limiting buckle assemblies 212. The limiting buckle assembly 212 includes a mounting part 2121 and two U-shaped blocks 2122.

The openings of the two U-shaped blocks 2122 can be rotatably set towards the two rotating placement seats 22 located on the same side, so that the openings of the U-shaped blocks 2122 can rotate within a certain range. The openings of the U-shaped blocks 2122 can be rotatably set towards the horizontal height of the limiting pin 221, which restricts the position and horizontal rotation angle of the limiting pin 221, facilitating loading and unloading. The rotating placement seat 22 moves upward to push the U-shaped blocks 2122 to rotate upward, so that the U-shaped blocks 2122 are released from the limitation of the limiting pin 221 and rotate. After completion, the rotating placement seat 22 lowers the U-shaped blocks 2122 to limit the limiting pin 221 again.

[0059] In another embodiment of the present invention, the two ends of the mounting member 2121 extend downward to form mounting portions, and the two U-shaped blocks 2122 are rotatably connected to the two mounting portions respectively. The gap between the U-shaped block 2122 and the carrier plate 21 facilitates the U-shaped block 2122 to rotate at a certain angle when it receives the action of the connecting column 35.
