Description

Technical Field

[0001] This utility model belongs to the field of motor rotor manufacturing technology, and in particular relates to a novel rotor assembly device. Background Technology

[0002] In the production process of motor rotors, permanent magnets (such as neodymium iron boron magnets) typically need to be precisely assembled onto an iron disc (magnetic yoke). Because permanent magnets are highly magnetic but brittle, traditional assembly methods often involve manual or mechanical pressing, which can easily lead to defects such as breakage and chipping of the magnets upon contact with the iron disc due to strong magnetic attraction and rigid impact. This severely affects product yield and production efficiency. Furthermore, the impact problem is even more pronounced in high-speed automated assembly, necessitating a device that can achieve smooth, gradual assembly.

[0003] Existing technologies lack effective structural designs to mitigate the impact of magnets attracting iron discs, making it difficult to balance assembly efficiency and product integrity. Utility Model Content

[0004] The purpose of this invention is to provide a novel rotor assembly device that can avoid rigid contact between the magnet and the iron disc during the assembly process, effectively reduce impact, prevent magnet breakage, and improve assembly yield and automation efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a novel rotor assembly device, comprising:

[0007] The clamping cylinder has a working platform on its top and several grippers arranged around the working platform.

[0008] The work platform is provided with several pivot pins around the central axis at the top of the work platform, which can be used to position the iron plate placed on the work platform.

[0009] The inclined block, fixed on the gripper, can be moved horizontally to directly above the iron plate or pulled away from above the iron plate under the drive of the gripping cylinder;

[0010] The inclined block has an inclined slope at one end near the working platform to support the magnet and guide the magnet to slowly descend along the inclined slope to the surface of the iron plate when the inclined block moves horizontally.

[0011] As a preferred technical solution of this utility model, the inclination angle of the inclined slope of the inclined block is 15° to 45°.

[0012] As a preferred embodiment of this invention, the number of grippers is not less than three.

[0013] As a preferred embodiment of this utility model, the clamping cylinder is a double-acting cylinder, and the clamping cylinder is controlled by a solenoid valve to extend and retract, thereby driving the inclined block to achieve reciprocating motion.

[0014] As a preferred technical solution of this utility model, it also includes a PLC control system, which is electrically connected to the clamping cylinder and is used to control the timing of the clamping cylinder's actions.

[0015] This utility model has the following beneficial effects:

[0016] The slow-descent structure of the inclined block avoids direct rigid collision between the magnet and the iron plate, significantly reducing the risk of the magnet breaking due to impact.

[0017] By utilizing the combined effect of magnetic attraction and gravity, magnets can be automatically and smoothly attached, improving assembly consistency and product yield.

[0018] It has a simple structure, reliable operation, and is easy to integrate with automated production lines to improve production efficiency.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please see Figure 1-2 As shown, this utility model discloses a novel device for efficiently assembling rotors, comprising the following main components: a clamping cylinder 1, which employs a double-acting design and uses an external solenoid valve to precisely control its extension and retraction, thereby driving the inclined block 4 to achieve stable and reliable reciprocating motion. A robust working platform 3 is integrated at the top of the clamping cylinder 1, with multiple grippers 2 arranged in the central area of ​​the platform. The number of grippers is no less than three, providing balanced support and clamping effect. A set of pins 5 are arranged around the central axis of the working platform 3. These pins are used to precisely position the iron disc 6 placed on the platform, ensuring the iron disc maintains a stable position during assembly. The inclined block 4 is fixedly mounted on the grippers 2 and, driven by the clamping cylinder 1, can move horizontally to directly above the iron disc 6 or be completely removed from that position. The inclined block 4 has an inclined slope 401 at one end near the working platform 3, with an inclination angle of 30°. This slope reliably supports the magnet 7 and guides the magnet 7 to descend slowly and smoothly onto the iron plate 6 surface as the inclined block 4 moves horizontally, preventing damage to the magnet due to impact. The device also includes a PLC control system, which is connected to the clamping cylinder 1 via electrical wiring. This system is used to program and control the timing of the clamping cylinder 1's actions, achieving automated operation and improving assembly efficiency and accuracy.

[0028] The assembly and working principle of this device is as follows, and the specific process is divided into four stages:

[0029] Iron disc positioning stage: Place the iron disc 6 to be assembled on the work platform 3, and fit the shaft pin 5 into the center hole of the iron disc 6. The precise fit between the shaft pin 5 and the center hole of the iron disc 6 ensures that the radial position of the iron disc 6 is fixed. At this time, the top surface of the iron disc 6 is parallel to the top surface of the work platform 3 without tilting or offset.

[0030] The inclined block reset stage: The PLC control system sends a command to the solenoid valve of the clamping cylinder 1 to control the intake of air in the clamping cylinder 1, the piston rod extends, and the gripper 2 moves synchronously towards the center of the work platform 3 until the inclined block 4 moves directly above the iron plate 6; at this time, the extension direction of the inclined slope 401 of the inclined block 4 is aligned with the position of the magnet mounting groove on the iron plate 6.

[0031] Magnet slow-descent and attraction stage: The magnet 7 is fitted to the appropriate size by manual or automated feeding mechanism such as a vacuum suction cup robotic arm and placed on the inclined slope 401 of the inclined block 4. One end of the magnet 7 is in close contact with the slope, while the other end is suspended and aligned with the mounting groove of the iron plate 6. Then, the PLC control system controls the clamping cylinder 1 to exhaust air, the piston rod retracts, and the clamping claw 2 moves outward synchronously. The inclined block 4 is pulled away horizontally with the clamping claw 2. As the inclined block 4 moves, the supporting force of the inclined slope 401 on the magnet 7 gradually weakens. The magnet 7 slowly slides down the slope under its own gravity. The sliding speed can be controlled by adjusting the exhaust throttle valve of the clamping cylinder 1. At the same time, as the distance between the magnet 7 and the iron plate 6 decreases, the magnetic attraction force of the iron plate 6 on the magnet 7 gradually increases. Under the combined action of gravity and magnetic attraction, the magnet 7 gradually approaches the upper surface of the iron plate 6 in a gentle posture and finally falls into the mounting groove without impact, completing the attraction and assembly.

[0032] Preparation phase of the cycle: After the magnet 7 is assembled, the PLC control system controls the clamping cylinder 1 to re-intake air, driving the gripper 2 and the inclined block 4 to return to the position directly above the iron plate 6. The worker or robot arm removes the assembled rotor, replaces the new iron plate 6, and enters the next assembly cycle.
