Description

Technical Field

[0001] This utility model relates to the technical field of motor rotor production equipment, and in particular to a core feeding mechanism. Background Technology

[0002] Silicon steel sheets are a soft magnetic alloy of silicon and iron with extremely low carbon content, typically containing 0.5% to 4.5% silicon, and are manufactured through hot and cold rolling. They are generally less than 1 mm thick, hence the term "thin sheet." Adding silicon increases the resistivity and maximum permeability of iron, while reducing coercivity, core loss (iron loss), and magnetic aging. They are mainly used to manufacture the cores of various transformers, motors, and generators.

[0003] However, the conventional feeding of the iron core is done manually. Manual feeding requires workers to clamp and transport the rotor iron core to the installation station. This feeding method is very inefficient and requires a high labor cost, which cannot meet the needs of mass production. Manual feeding will greatly increase the workload of workers, and the iron core needs to be repositioned during subsequent injection molding and encapsulation. This requires additional positioning equipment or manual positioning, which further increases the cost. Utility Model Content

[0023] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] like Figure 1 and Figure 2As shown, this embodiment provides a core feeding mechanism, which includes a housing 10. An upper turntable 11 and a lower turntable 12 are respectively provided at the top and bottom of the housing 10. A connecting rod 13 is fixed between the upper turntable 11 and the lower turntable 12 to fix the upper turntable 11 and the lower turntable 12. A rotary drive component 14 is also provided inside the housing 10 to drive the lower turntable 12 to rotate and drive the upper turntable 11 to rotate. An electrical control box 15 for controlling the operation of internal components is provided on the side of the housing 10. Universal casters 16 and feet 17 are provided at the four corners of the bottom of the housing 10. The universal casters 16 facilitate transportation, and the feet 17 fix the housing 10.

[0025] In this embodiment, the upper turntable 11 is provided with two positioning slots spaced apart. A core positioning plate 20 is detachably provided in each positioning slot. A limiting slot is provided on the side wall opposite to the positioning slot. A locking block 21 is provided in the limiting slot and is fixedly connected to the core positioning plate 20. The core positioning plate 20 is suspended and fixed in the positioning slot by the locking block 21. The core positioning plate 20, the locking block 21 and the upper end surface of the upper turntable 11 are flush.

[0026] like Figure 3 As shown, each iron core positioning plate 20 is provided with multiple positioning guide cavities 22. Each positioning guide cavity 22 is provided with a guide block 23 that matches the winding groove of the iron core. By setting multiple positioning guide cavities 22, multiple iron cores can be fed at one time, improving efficiency. In addition, the guide block 23 that matches the winding groove of the iron core avoids the problem of iron core deviation during the feeding process, improving the stability and accuracy of iron core feeding.

[0027] To facilitate core feeding and ensure the core passes through the corresponding positioning guide cavity 22, two core lifting components 30 corresponding to the core positioning plate 20 are provided on the lower turntable 12. Figure 4 , Figure 5 and Figure 6As shown, the iron core lifting component 30 includes a pusher plate 31, a screw drive unit 32 for driving the pusher plate 31 to rise and fall, and several guide rods 33 that pass through the pusher plate 31 and connect to the iron core positioning plate 20. The iron core passes through two of the guide rods 33, and the tops of the two guide rods 33 are inserted into guide blocks 23 in the corresponding positioning guide cavities 22. The iron cores are stacked on the corresponding two guide rods 33. When the screw drive unit 32 drives the pusher plate 31 to rise, the pusher plate 31 pushes the iron cores passing through the guide rods 33 to rise. The topmost iron core passes through the positioning guide cavity 22, with its upper part exposed on the upper turntable 11. This prevents the iron core from being completely pushed out of the positioning guide cavity 22, thus avoiding inaccurate positioning and facilitating removal by the subsequent material handling mechanism. Simultaneously, two iron core lifting components 30 are provided. When one of the iron core lifting components 30 runs out of iron cores, the lower turntable 12 is rotated by the rotation drive component 14 to replace it, achieving alternating operation without stopping the machine for material loading, effectively improving work efficiency.

[0028] In addition, the core lifting component 30 also includes a guide rod fixing plate 34 fixed on the lower turntable 12. The guide rod 33 has small diameter sections 330 at both ends, which are respectively inserted into the guide rod fixing plate 34 and the guide block 23. The guide rod fixing plate 34 has slide rods 35 parallel to the guide rod 33 at its four corners. The push plate 31 is slidably connected to the slide rods 35 through guide shafts. The top of the slide rods 35 is inserted into the core positioning plate 20. The guide shafts are made of linear bearings, and the bottom of the push plate 31 has a fixing groove for the guide shafts to be inserted. Through this structure, the guide rod fixing plate 34 provides a stable bottom support for the guide rod 33, ensuring that the guide rod 33 will not shake or deviate during operation. The insertion design of the small diameter sections 330 at both ends of the guide rod 33 into the guide rod fixing plate 34 and the guide block 23 not only facilitates installation and disassembly. Meanwhile, the guide rod fixing plate 34 has four sliding rods 35 parallel to the guide rod 33 at its four corners, and the pusher plate 31 is slidably connected to the sliding rods 35 through the guide sliding shaft, so that the pusher plate 31 can maintain a stable movement trajectory during the rising or falling process, avoiding jamming or tilting.

[0029] In an optional embodiment, to ensure the accuracy of core positioning, the pusher plate 31 is provided with a positioning groove 310 corresponding to the positioning guide cavity 22. The bottom of the positioning groove 310 is provided with positioning protrusions 311 that match the winding groove of the core on opposite sides. The bottom of the positioning groove 310 is also provided with sliding holes 312 for the guide rod 33 to pass through on opposite sides. The bottom core is inserted into the positioning protrusion 311 and passes through the guide rod 33. This avoids the slight vibration generated when the screw drive unit 32 drives the pusher plate 31 from moving the core, effectively preventing the core from being misaligned.

[0030] In this embodiment, the lead screw drive unit 32 includes a transmission lead screw 320 rotatably connected to the upper turntable 11 and the lower turntable 12 via a bearing housing, and a drive motor 321 disposed on the lower turntable 12 and connected to the transmission lead screw 320 via a synchronous pulley and a synchronous belt. The transmission lead screw 320 is threadedly connected to a push plate 322, which is movably connected to one of the connecting rods 13 via a linear bearing. The push plate 322 is provided with a fixing block 323 connected to the pusher plate 31. After the drive motor 321 starts, it drives the transmission lead screw 320 via the synchronous pulley and synchronous belt. The screw 320 rotates, and since the screw 320 is threadedly connected to the push plate 322, the push plate 322 moves up and down with the rotation of the screw 320. During this process, the push plate 322 is movably connected to the connecting rod 13 through a linear bearing, which ensures the stability and smoothness of the push plate 322 during the up and down movement. At the same time, the fixed block 323 on the push plate 322 is connected to the push plate 31. When the push plate 322 moves up and down, it will drive the push plate 31 to move up and down synchronously, thereby realizing the feeding operation of the iron core.

[0031] In an optional embodiment, in order to enable the raised iron core to pass smoothly through the guide block 23 and be lifted to the upper end of the positioning guide cavity 22, the bottom of the guide block 23 extends axially and gradually decreases in size to form a conical insertion part. The design of this conical insertion part can play a good guiding role. When the iron core is raised close to the guide block 23, the conical insertion part can gradually guide the iron core to a suitable position and angle, so that the iron core passes through the guide block 23 more smoothly and is then lifted to the upper end of the positioning guide cavity 22. This avoids problems such as jamming and deviation that may occur when the iron core passes through the guide block 23, and improves the efficiency and stability of iron core feeding.

[0032] In an optional embodiment, the rotary drive component 14 employs a hollow shaft rotary platform. This platform offers high rotational accuracy and stability, ensuring precise and continuous power support for core feeding during the drive process. Its unique hollow shaft design not only facilitates wiring layout and connection, reducing potential interference and malfunctions caused by cluttered wiring, but also makes the entire mechanism more compact, saving installation space. Furthermore, the hollow shaft rotary platform possesses excellent load-bearing capacity, adapting to the feeding requirements of cores of different specifications and weights, further enhancing the applicability and reliability of the core feeding mechanism.

[0033] In summary, this core feeding mechanism achieves automated feeding, greatly improving feeding efficiency. Compared to traditional manual feeding methods, it eliminates the need for workers to individually pick up and move cores, thus reducing labor costs and meeting the demands of mass production. The core positioning plate 20 and positioning guide cavity 22 on the upper turntable 11, in conjunction with the core lifting component 30 on the lower turntable 12, achieve precise core positioning. The guide block 23 inside each positioning guide cavity 22 matches the winding groove of the core, ensuring the stability and accuracy of the core during feeding, reducing the need for repositioning during subsequent core injection molding and further reducing costs. Simultaneously, multiple core positioning plates 20 and core lifting components 30 are provided. When one core lifting component 30 has finished feeding a core, the lower turntable 12 is rotated by the rotation drive component 14 for replacement, enabling alternating operations without stopping the machine for reloading, effectively improving work efficiency.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
