Description

Technical Field

[0001] This utility model relates to the field of motor assembly technology, and in particular to a rotor magnet insertion machine. Background Technology

[0002] Permanent magnet motors typically consist of a rotor and a stator. A common rotor core uses an internally inserted magnetic strip structure, where magnetic strips made of permanent magnet material are inserted inside the rotor core, serving as the motor's rotating mechanism. The interaction between the rotor and stator generates a rotating magnetic field, which drives the rotor to rotate, thereby outputting electrical energy.

[0003] During the manufacturing process, the rotor core requires the magnetic strips to be accurately inserted into their corresponding positions. Current technology typically relies on manual operation, where the magnetic strips are manually inserted into the slots in the core. However, this manual assembly method suffers from low production efficiency, large errors, and a high defect rate, especially when there are a large number of magnetic strips, which can easily lead to assembly errors and quality problems.

[0004] To address these issues, Chinese utility model patent CN219287340U discloses an automatic rotor magnetic strip insertion device. This device includes a frame, with a dust cover fixedly connected to the rear, a pad fixedly connected to the front, a button box fixed to the left side of the pad, and a cylinder fixedly connected to the middle. One end of the cylinder is fixedly connected to a rotor positioning fixture, and the rotor is movably engaged within the fixture. A servo module with a servo motor is also fixedly connected to the middle of the frame. A magnetic strip feeding mechanism is connected to the outside of the frame via a bracket. The feeding mechanism houses an insertion component and a magnet feeding slot containing magnetic strips. During operation, the magnetic strips and rotor are manually placed into the magnet feeding slot and rotor positioning fixture, respectively. The insertion component automatically completes the magnetic strip insertion, thereby improving the efficiency of magnetic strip insertion.

[0005] However, in practical applications, due to the rigid design of the insertion component, it is difficult to precisely control the force applied when it first contacts the magnetic strip. This can easily lead to damage to the magnetic strip due to excessive force, which not only affects the quality of the final product but also reduces the efficiency of the overall rotor assembly.

[0006] In view of this, the inventor conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

Detailed Implementation

[0031] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0032] Reference Figures 1 to 6A rotor magnetizing machine includes a frame 10 with an opening on one side. With the open side of the frame 10 as the front, magnetizing assemblies and magnetic strip feeding assemblies are respectively provided on the front and rear sides of the top surface of the frame 10. The magnetizing assembly includes a vertically arranged mounting frame 21, on which a first mounting plate 22 and a second mounting plate 23 are arranged at intervals. A magnetic strip guide block 221 is provided on the top surface of the first mounting plate 22. At least one magnetic strip guide hole 222 extending downwards and penetrating the first mounting plate 22 is recessed on the top surface of the magnetic strip guide block 221. At least one magnetic strip guide hole 222 is provided on the rear side of the magnetic strip guide block 221. 2. A connected magnetic strip guide groove 223; A first cylinder 231 is vertically provided on the top surface of the second mounting plate 23. The output end of the first cylinder 231 passes through the second mounting plate 23 downward and is provided with a movable block 232. The movable block 232 is located above the magnetic strip guide block 221. At least one pressing groove 233 is provided inwardly on the bottom surface of the movable block 232. A pressing block 234 for entering the magnetic strip guide hole 222 is provided in the pressing groove 233. In this embodiment, the pressing block 234 is long and narrow. A first elastic member 235 is also provided between the top of the pressing block 234 and the top wall of the pressing groove 233.

[0033] The mounting bracket 21 is provided with a sliding seat 31 that can move back and forth. The bottom of the sliding seat 31 is provided with a vertically arranged second cylinder 32. The output end of the second cylinder 32 passes through the sliding seat 31 and is provided with a rotating seat 33 for placing the rotor core. The magnetic strip feeding assembly includes a magnetic shielding plate 41 that can move left and right. The top surface of the magnetic shielding plate 41 is recessed with multiple receiving grooves 411 for accommodating magnetic strips. The top of the magnetic shielding plate 41 is provided with a pushing assembly that can move back and forth and push the magnetic strips in the receiving grooves 411 into the magnetic strip guide groove 223.

[0034] During operation, the buffering effect of the first elastic element 235 can reduce the direct impact of the pressing block 234 on the magnetic strip, ensuring that the magnetic strip is not subjected to excessive impact force during the insertion of the rotor core, thereby effectively reducing the breakage rate of the magnetic strip and improving the stability of the production process and the quality of the product.

[0035] Reference Figures 1 to 6The top surface of the frame 10 is recessed with a rectangular slot 11. A receiving frame 12 is provided in the slot 11. The top of the receiving frame 12 is fixedly connected to the bottom of the sliding seat 31. A second cylinder 32 is provided in the receiving frame 12. Two slide rails 13 are arranged horizontally in the front-back direction on both sides of the top of the slot 11. A sliding block 312 that slides with the slide rails 13 is provided at the bottom of the sliding seat 31. A third cylinder 35 is arranged horizontally in the front-back direction on the rear side of the sliding seat 31. The output end of the third cylinder 35 is fixedly connected to the receiving frame 12. During operation, the third cylinder 35 can drive the receiving frame 12 and the sliding seat 31 to move horizontally back and forth along the frame 10. When the sliding seat 31 moves to below the magnetic strip inlet hole 222, the second cylinder 32 drives the rotating seat 33 to move upward, so that the rotor core abuts against the bottom surface of the first mounting plate 22, thereby enabling the magnetic strip insertion operation.

[0036] Reference Figures 1 to 6 The top of the pressing block 234 has two protruding limiting portions 2341. The length of the two limiting portions 2341 is greater than the opening width of the pressing groove 233. By setting the limiting portions 2341, the pressing block 234 can be prevented from falling out of the pressing groove 233. The rear side of the frame 10 is provided with a first lead screw 14 arranged horizontally in the left-right direction. The first lead screw 14 is provided with a movable first slider (not shown in the figure). The top of the first slider is provided with the aforementioned magnetic shielding plate 41. The front side of the magnetic shielding plate 41 is provided with multiple discharge holes 412 for magnetic strips to pass through in the left-right direction. The multiple discharge holes 412 correspond one-to-one with multiple receiving grooves 411. In this embodiment, the first lead screw 14 is driven by a motor (not shown in the figure). The motor drives the first lead screw 14 to rotate, thereby driving the first slider to move on the first lead screw 14. In this way, when the magnetic strip in a receiving groove 411 is exhausted, the first slider can drive the magnetic shielding plate 41 connected to it to move, thereby ensuring that the magnetic strip can be continuously supplied and improving the efficiency of magnetic strip insertion.

[0037] Reference Figures 1 to 9The pushing assembly includes a stand 51 erected on the rear side of the magnetic shielding plate 41. The top of the stand 51 is provided with a horizontal plate 52 arranged horizontally in the front-back direction. The bottom surface of the horizontal plate 52 is provided with a second lead screw 53 arranged horizontally in the front-back direction. The second lead screw 53 is provided with a movable second slider 531. The bottom surface of the second slider 53 is provided with a mounting block 54 extending downward into the receiving groove 411. The front side of the mounting block 54 is provided with a mounting shaft 55. An "L"-shaped pushing block 56 is movably sleeved on the mounting shaft 55. A second elastic element 57 is also sleeved on the mounting shaft 55 between the pushing block 56 and the mounting block 54. A stop block 58 fixedly connected to the mounting block 54 is also provided below the mounting shaft 55. In this way, when pushing the magnetic strip, the second elastic element 57 between the pushing block 56 and the mounting block 54 can achieve a more stable pushing action and avoid damage to the magnetic strip due to excessive pushing force. Meanwhile, the stop block 58 can effectively limit the movement range of the pusher block and ensure stability during the pushing process.

[0038] Reference Figures 1 to 9 In this invention, the first elastic element 235 and the second elastic element 57 are respectively the first spring and the second spring. The rotating seat 33 can be rotated by a rotary cylinder. To further improve the operating accuracy of this invention, a photoelectric sensor 60 for detecting the placement of the rotor core can be installed on one side of the rotating seat 33. This photoelectric sensor 60 can detect the placement of the rotor core in real time, avoiding errors or malfunctions caused by the rotor core not being placed or being improperly placed, and further improving the accuracy and stability of this invention during operation.

[0039] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
