Description

Technical Field

[0001] This utility model belongs to the field of motor rotor processing technology, and more specifically, it relates to a motor rotor magnet adhesive. Background Technology

[0002] With the continuous improvement of permanent magnet material performance and the development of motor technology, permanent magnet motors have been widely and actively used in various fields and directions. High-performance permanent magnet motors can bring high efficiency and high economic benefits. As an important component of permanent magnet motors, the manufacturing process of the permanent magnet rotor directly affects the performance of the permanent magnet motor.

[0003] A permanent magnet rotor consists of a shaft and magnets bonded to its surface. Bonding the rotor magnets is a crucial step in motor manufacturing, involving fixing the permanent magnets (magnets) to the rotor surface. This process requires meticulous operation and strict quality control to ensure motor performance and reliability.

[0004] Currently, there are two bonding processes for magnets onto the rotor shaft of motors: 1. First, attach the unmagnetized magnets to the shaft, then magnetize the rotor after the magnets have been attached; 2. First, magnetize individual magnets and then attach them to the shaft. The first method involves attaching the magnets to the shaft without magnetism, making the process simple, but the magnetization performance is poor. With the second method, because the magnetized magnets are magnetic, they are easily attracted by the magnetic force when near the shaft, potentially causing them to collide uncontrollably and break. To avoid this uncontrollable phenomenon during installation of the magnetized magnets and shaft, some companies use specialized equipment for magnet transfer; however, most of this equipment is bulky and complex, increasing production costs. Utility Model Content

[0019] In one possible implementation, the mounting bracket includes a mounting body and an adjusting member connected to the mounting body. The adjusting member is a telescopic member that extends and retracts along a second path, which is perpendicular to the first path.

[0024] A drive gear, coaxially connected to the drive shaft of the rotary actuator; and

[0025] The driven ring has driving teeth on its outer circumferential surface that mesh with the driving gear. The driven ring is used for insertion and engagement with the optical axis. The adhesive assembly is connected to the inner wall of the driven ring.

[0026] In one possible implementation, the moving component includes:

[0027] A mobile drive is located on the rack;

[0028] A movable lead screw, mounted on the frame and connected to the movable drive, has its axis parallel to the first path, and a fixed bracket connected to the nut of the movable lead screw; and

[0029] A slide rail is provided on the frame and parallel to the first path, and the fixed bracket is slidably connected to the slide rail.

[0030] In one possible implementation, the paste component includes:

[0031] Switching driver, connected to the fixed bracket; and

[0032] An adhesive applicator is connected to the switching driver, which controls the adhesive applicator to rotate around a first path or extend and retract in the vertical direction, so that the adhesive applicator switches between the working state and the standby state.

[0033] In one possible implementation, the adhesive mechanism includes a connecting rod and an adhesive attached to one end of the connecting rod, the other end of the connecting rod being connected to the switching driver, the switching driver being used to drive the connecting rod to rotate about a first path as an axis, so that the switching driver switches between the working state and the standby state.

[0034] In one possible implementation, the clamping unit further includes a buffer pad connected to the clamping assembly, the buffer pad being a flexible member for contacting the optical axis.

[0035] The advantages of this invention's motor rotor magnet pasting device are as follows: Compared with existing technologies, this invention places the optical shaft on a support unit during use, and a clamping assembly fixes the optical shaft, ensuring its stability and preventing movement during pasting. A moving component drives a fixed bracket to move along a first path to a designated position, and the pasting component switches from standby to working state. A rotating unit drives the pasting component or clamping assembly to rotate, causing the pasting component to paste the magnet along the circumference of the optical shaft. After pasting the magnet, the pasting component switches back to standby state, and the optical shaft and magnet are removed, avoiding interference with the pasting component. This invention, by fixing the optical shaft with a clamping unit and using the pasting component to paste the magnet along the circumference of the optical shaft, overcomes the influence of magnetic attraction on pasting accuracy, thus improving pasting precision. Furthermore, this invention is simple; after fixing the optical shaft, the magnet can be pasted using the rotating and pasting units, reducing the equipment's footprint and lowering production costs.

[0043] Please refer to the following: Figures 1 to 3 The present invention provides a motor rotor magnet adhesive. The motor rotor magnet adhesive includes a support base 1, a frame 2, an adhesive unit 3, a support unit 4, a clamping unit 5, and a rotating unit 6. The support base 1 is disposed on a support surface; the frame 2 is connected to the support base 1 and extends upwards from the support base 1; the adhesive unit 3 includes a moving component 301 connected to the frame 2, a fixed bracket 303 connected to the moving component 301, and an adhesive component 302 connected to the fixed bracket 303. The moving component 301 drives the fixed bracket 303 to move along a first path, and the adhesive component 302 is used to apply the magnet... The steel is bonded to the optical axis 7. The bonding component 302 has a working state of being bonded to the optical axis 7 and a standby state of being separated from the optical axis 7. The support unit 4 is disposed on the bearing base 1 and is used to support the optical axis 7. The clamping unit 5 includes a clamping seat 501 disposed on the bearing base 1 and a clamping component 502 connected to the clamping seat 501. The clamping component 502 is used to clamp the optical axis 7. The rotating unit 6 is connected to the bonding component 302 and / or the clamping component 502. The rotating unit 6 is used to drive the bonding component 302 and / or the clamping component 502 to rotate around the axis of the optical axis 7.

[0044] Compared with the prior art, the motor rotor magnet pasting device provided by this utility model places the optical axis 7 on the support unit 4 during use, and the clamping component 502 fixes the optical axis 7 to ensure its stability and prevent movement during pasting. The moving component 301 drives the fixed bracket 303 to move along the first path to the designated position, and the pasting component 302 switches from standby to working state. The rotating unit 6 drives the pasting component 302 or the clamping component 502 to rotate, so that the pasting component 302 pastes the magnet along the circumference of the optical axis 7. After the magnet is pasted, the pasting component 302 switches to standby state, and the optical axis 7 and the magnet are removed to avoid interference with the pasting component 302. This utility model, by fixing the optical axis 7 with the clamping unit 5 and using the pasting component 302 to paste the magnet along the circumference of the optical axis 7, overcomes the influence of magnetic attraction on the pasting accuracy and improves the pasting accuracy. In addition, the present invention is simple. After fixing the optical axis 7, the magnet can be pasted by rotating unit 6 and pasting unit 3, which reduces the footprint of the equipment and lowers the production cost.

[0045] Optionally, the clamping component 502 can be a robotic arm to fix the optical axis 7 by clamping.

[0046] It should be noted that the supporting surface refers to the area, such as the ground or workbench, that provides support to the load-bearing base 1.

[0047] In some embodiments, please refer to Figure 1 and Figure 3 The support unit 4 includes a support base 401, a mounting frame 402, and multiple support wheels 403. The support base 401 is connected to the bearing base 1. The mounting frame 402 is connected to the support base 401 and has multiple mounting positions, which are arranged in an arc shape. The multiple support wheels 403 are arranged one-to-one with the multiple mounting positions, and the support wheels 403 are rotatably connected to the mounting positions to support the optical axis 7.

[0048] In this embodiment, the support wheel 403 contacts the optical axis 7 and provides support for the optical axis 7. When pasting the magnet, if the rotating unit 6 is connected to the clamping assembly 502, it drives the clamping assembly 502 to rotate around the first path, thereby realizing the rotation of the optical axis 7. As the optical axis 7 rotates, the pasting assembly 302 pastes the magnet along the circumference of the optical axis 7, and the support wheel 403 rotates synchronously with the optical axis 7, reducing the friction force on the outer circumferential surface of the optical axis 7 and avoiding wear on the optical axis 7.

[0049] Optionally, the axis of the support wheel 403 is parallel to the first path.

[0050] Optionally, the mounting bracket 402 is located directly below the optical axis 7, and the support wheel 403 provides support for the optical axis 7.

[0051] In some embodiments, please refer to Figure 1 Multiple support units 4 are provided, and the multiple support units 4 are distributed in a mirror symmetrical manner with the first path as the axis of symmetry.

[0052] In this embodiment, support units 4 are provided on both sides of the optical axis 7 to provide support force on the opposite sides of the optical axis 7, ensuring that the optical axis 7 and the clamping assembly 502 are coaxially arranged.

[0053] Optionally, the support unit 4 is slidably connected to the bearing base 1 along a second path, which is perpendicular to the first path. In this embodiment, the position of the support unit 4 can be adjusted according to the diameter of the optical axis 7, thereby ensuring the contact area between the support unit 4 and the optical axis 7, improving the stability of the optical axis 7, and also ensuring that the optical axis 7 is coaxial with the clamping unit 5. The support unit 4 can be connected to a lead screw or telescopic component to adjust its position in the second path.

[0054] In some embodiments, please refer to Figure 1 The mounting bracket 402 includes a mounting body and an adjusting member connected to the mounting body. The adjusting member is a telescopic member that extends and retracts along a second path, which is perpendicular to the first path. The support base 401 and / or the clamping base 501 move in the vertical direction to keep the center of the clamping assembly 502 at the same height as the axis of the optical axis 7.

[0055] The adjusting member extends and retracts along the second path, adjusting the position of the mounting body along the second path, thereby providing effective support for optical axes 7 of different diameters. Additionally, the support base 401 or clamping base 501 moves vertically, adjusting the height of the optical axis 7 or clamping assembly 502 when the diameter of the optical axis 7 changes, so that the axes of the optical axis 7 and the clamping assembly 502 coincide, facilitating the attachment assembly 302 to attach magnets along the outer circumferential surface of the optical axis 7. This embodiment can be adapted to optical axes 7 of different diameters and ensures that the optical axis 7 and the clamping assembly 502 are coaxially arranged.

[0056] Optionally, the adjusting element can be a pneumatic or hydraulic telescopic component.

[0057] In some embodiments, please refer to Figure 1 and Figure 2 The rotating unit 6 includes a rotating driver 601 and a transmission mechanism 602. The transmission mechanism 602 is connected to the driving end of the rotating driver 601. The rotating driver 601 is used to drive the transmission mechanism 602 to rotate. The transmission mechanism 602 is connected to the clamping assembly 502 and / or the adhesive assembly 302.

[0058] The rotary driver 601 drives the transmission mechanism 602 to rotate, thereby realizing the rotation of the clamping component 502 or the adhesive component 302, so that the adhesive component 302 can adhere the magnet to the optical axis 7 in the circumferential direction.

[0059] Optionally, the rotary driver 601 is a motor.

[0060] Optionally, the transmission mechanism 602 is a reducer and is connected to the clamping assembly 502. The clamping assembly 502 is coaxially arranged with the optical axis 7 and controls the optical axis 7 to rotate around its own axis, so that magnets can be pasted circumferentially on the outer wall of the optical axis 7 while the pasting assembly 302 is fixed.

[0061] In some embodiments, please refer to Figure 2 The rotating unit 6 is connected to the adhesive assembly 302. The transmission mechanism 602 includes a driving gear and a driven ring. The driving gear is coaxially connected to the drive shaft of the rotary driver 601. The outer circumferential surface of the driven ring has driving teeth that mesh with the driving gear. The inner ring of the driven ring is used for insertion and engagement with the optical shaft 7. The adhesive assembly 302 is connected to the inner wall of the driven ring.

[0062] The optical axis 7 is inserted into the driven ring and is coaxially arranged with the driven ring. The rotary driver 601 drives the driving gear to rotate, thereby causing the driven ring meshed with the driving gear to rotate. After the adhesive assembly 302 switches to the working state, it rotates along with the driven gear, thereby attaching the magnet to the outside of the optical axis 7 circumferentially. In this embodiment, the magnet is attached to the outer wall of the optical axis 7 by driving the adhesive assembly 302 to rotate, without the need to rotate the optical axis 7.

[0063] In some embodiments, please refer to Figure 1 The moving component 301 includes a moving driver 3011, a moving screw 3012, and a slide rail 3013. The moving driver 3011 is mounted on the frame 2. The moving screw 3012 is mounted on the frame 2 and connected to the moving driver 3011. The axis of the moving screw 3012 is parallel to the first path. A fixed bracket 303 is connected to the nut of the moving screw 3012. The slide rail 3013 is mounted on the frame 2 and parallel to the first path. The fixed bracket 303 is slidably connected to the slide rail 3013.

[0064] The movable driver 3011 controls the rotation of the movable lead screw 3012, thereby causing the fixed bracket 303 connected to the movable lead screw 3012 to move along the axis of the lead screw (first path), moving the fixed bracket 303 to the position (designated position) where the magnet needs to be pasted on the optical axis 7, so that the pasting component 302 can paste the magnet onto the outside of the optical axis 7. In this embodiment, there is no need for manual movement of the pasting component 302, realizing automated production and improving pasting efficiency.

[0065] Optionally, the mobile drive 3011 is a motor.

[0066] In some embodiments, please refer to Figure 1The adhesive component 302 includes a switching driver 3021 and an adhesive mechanism 3022. The switching driver 3021 is connected to the fixed bracket 303. The adhesive mechanism 3022 is connected to the switching driver 3021. The switching driver 3021 controls the adhesive mechanism 3022 to rotate around a first path or extend and retract in the vertical direction, so that the adhesive mechanism 3022 switches between working state and standby state.

[0067] When the switch driver 3021 is a telescopic component, the sticking extrusion is extended and retracted in the vertical direction to switch between the working state and the standby state. When the switch component is a motor, the motor is connected to a gear, and the sticking mechanism 3022 has a rack meshing with the gear. The rack extends in the vertical direction, and the rack moves up and down by rotating the gear, thus switching the sticking mechanism 3022 between the working state and the standby state.

[0068] Specifically, the adhesive is an existing magnetic adhesive device.

[0069] In some embodiments, please refer to Figure 1 The pasting mechanism 3022 includes a connecting rod and a pasting device connected to one end of the connecting rod. The other end of the connecting rod is connected to a switching driver 3021. The switching driver 3021 is used to drive the connecting rod to rotate around a first path as a pivot, so that the switching driver 3021 switches between a working state and a standby state.

[0070] The switching driver 3021 drives the end of the connecting rod to rotate around the first path, thereby enabling the pasting mechanism 3022 to rotate around the first path, switching the pasting mechanism 3022 between the working state and the standby state.

[0071] In some embodiments, please refer to Figure 1 The clamping unit 5 also includes a buffer pad 5021 connected to the clamping assembly 502. The buffer pad 5021 is a flexible component used to contact the optical axis 7.

[0072] The buffer pad 5021 contacts the optical axis 7 to prevent the clamping assembly 502 from directly clamping and fixing the optical axis 7, which could cause wear on the surface of the optical axis 7.

[0073] Optionally, the cushioning pad 5021 can be a rubber component or an EVA component.

[0074] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
