Description

Technical Field

[0001] This invention relates to the field of motor rotor magnet assembly technology, and particularly to an assembly apparatus and method for rotor magnetic components. Background Technology

[0002] The rotor magnetic assembly on some motors includes an iron core and multiple rotor magnets. The iron core is cylindrical, and the multiple rotor magnets are used to bond to the outer peripheral wall of the iron core and are arranged in a ring at unequal intervals along the outer peripheral wall.

[0003] When assembling this type of rotor magnetic assembly (by bonding the rotor magnets to the iron core), each rotor magnet must be saturated with magnets before assembly. At this time, since each rotor magnet has a strong magnet and is arranged in a ring with unequal spacing, the magnetic force on each magnet is uneven during assembly. Therefore, each magnet must be bonded and assembled individually, which makes assembly difficult and further makes it difficult to control the assembly accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide an assembly apparatus and method for rotor magnetic components. The technical problem to be solved is how to make the assembly of rotor magnetic components easier and more controllable.

[0005] To achieve the above objectives, the solution of the present invention is as follows: An assembly apparatus for a rotor magnetic assembly includes: an assembly fixture, a dispensing mechanism, and a magnet mounting mechanism; The rotor magnetic assembly includes an iron core and multiple rotor magnets. The iron core is cylindrical, and the multiple rotor magnets are bonded to the outer peripheral wall of the iron core and arranged at intervals around the outer peripheral wall. The assembly fixture is used to clamp and fix the iron core. On the assembly fixture, a guide channel is provided for each rotor magnet bonding position of the iron core. After the iron core is clamped into the assembly fixture, each guide channel can extend radially from the outside to the outer peripheral wall of the iron core. Each guide channel corresponds to the installation position of a rotor magnet on the iron core, and the size of each guide channel is sufficient for one rotor magnet to pass through. The dispensing mechanism is used to dispense adhesive onto the outer peripheral wall of the iron core; The magnet mounting mechanism is used to push the rotor magnets along each guide channel into the outer peripheral wall of the iron core, so that the rotor magnets are bonded to the surface of the iron core.

[0006] Furthermore, the assembly fixture includes a clamping assembly and a positioning base; The clamping assembly is used to clamp and fix the iron core; The positioning seat can be detachably installed onto the clamping assembly, and each of the guide channels is provided on the positioning seat.

[0007] Furthermore, the clamping assembly includes a fixture base and a pressure cap; The fixture has a columnar part, one end of which has a radially protruding flange. The columnar part is used for housing the iron core, and the flange is used to abut against one axial end of the iron core to limit the position of the iron core in the axial direction of the columnar part. The gland can be detachably installed onto the fixture base. After installation, it elastically abuts against the other end of the iron core along the axial direction, so that the iron core is clamped between the gland and the retaining edge. The positioning seat is used to fit the outer ring of the iron core onto the fixture seat, and after fitting, it forms a circumferential snap-fit ​​positioning with the fixture seat.

[0008] Furthermore, the pressure cap is mounted on the fixture seat by a locking device, which includes a locking rod and a compression spring; The locking rod axially penetrates the pressure cap, with an operating handle at one end and a locking pin protruding radially at the other end. A locking pin hole is formed on the fixture seat, and a radially outwardly extending groove is provided on the side wall of the locking pin hole. The groove includes an axial groove segment extending axially along the locking pin hole and a circumferential groove segment extending circumferentially along the locking pin hole. The axial groove segment extends to the opening end of the locking pin hole, and the locking pin is inserted into the locking pin hole through the axial groove segment and is engaged in the circumferential groove segment after the locking rod is rotated. The compression spring is compressed and elastically pressed between the operating handle and the pressure cap, and is used to press the pressure cap against the iron core after installation.

[0009] Furthermore, the dispensing mechanism includes a fixture rotation mechanism, a dispensing head, and a dispensing head driving mechanism; The jig rotation mechanism is used to insert the clamping assembly, and after insertion, it drives the clamping assembly to rotate around the axis of the iron core on it. The dispensing head is used to dispense adhesive. The dispensing head drive mechanism is used to drive the dispensing head to move to the jig rotation mechanism, so that the dispensing head outlet is aligned with the outer peripheral wall of the iron core on the clamping assembly placed on the jig rotation mechanism.

[0010] Furthermore, the fixture rotation mechanism includes a placement base, a rotary motor, and a connector; The placement seat forms a placement groove for inserting the clamping assembly. After insertion, the outer peripheral wall of the clamping assembly engages with the inner side wall of the placement groove, allowing the clamping assembly to rotate within the placement groove. The axis of rotation is the axis of the iron core. The connector is located at one end of the placement slot. In the connector and the clamping assembly, one end has a protrusion and the other end has a groove. After the clamping assembly is placed into the placement slot, the protrusion slides into the groove so that the connector and the clamping assembly form a circumferential engagement. A rotary motor is connected to the connector to drive the connector to rotate, which in turn drives the clamping assembly to rotate within the placement slot.

[0011] Furthermore, the magnet mounting mechanism includes a turntable and a magnet pushing device; The turntable is used to place the assembly fixture so that it can rotate around the iron core axis; The magnet pushing device is set on the periphery of the turntable. The assembly fixture can push the rotor magnet towards the turntable. During the rotation of the turntable carrying the assembly fixture, each guide channel is aligned with the rotor magnet pushing direction of the magnet pushing device, so that the rotor magnet can pass through the guide channel and reach the outer peripheral wall of the iron core through the magnet pushing device.

[0012] Furthermore, there are two magnet pushing devices, and the rotor magnets pushed out by the two magnet pushing devices have different polarities.

[0013] A method for assembling a rotor magnetic assembly, using the rotor magnetic assembly assembly apparatus as described above, includes the following steps: Step 1: Clamp the iron core using the clamping assembly; Step 2: Place the clamping assembly into the jig rotation mechanism, rotate the clamping assembly through the jig rotation mechanism, and apply glue to the rotor magnet bonding position on the outer periphery of the iron core on the clamping assembly through the glue dispensing head. Step 3: After dispensing the adhesive, remove the clamping assembly from the jig rotation mechanism, install the positioning seat onto the clamping assembly, and then place the clamping assembly with the positioning seat installed onto the turntable. Step 4: The turntable drives the positioning seat to rotate, and the two magnet pushing devices push the rotor magnets of the corresponding polarity through the corresponding guide channels to the outer peripheral wall of the iron core, so that the rotor magnets are attached to the outer peripheral wall of the iron core. Step 5: Remove the iron core with the rotor magnet attached from the clamping assembly.

[0014] The beneficial effects of the present invention after adopting the above solution are as follows: by setting an assembly fixture to clamp and fix the iron core, and opening a radially extending guide channel with a size that allows only one rotor magnet to pass through at each rotor magnet bonding position on the assembly fixture, the guide channel can constrain the position of each rotor magnet as it is pushed from the outside to the outer peripheral wall of the iron core during magnet installation, eliminating the deviation, tilting or misalignment caused by the magnet's own attraction or manual alignment deviation, so that each rotor magnet can be accurately bonded to the preset position, significantly improving the layout accuracy of multiple rotor magnets on the outer periphery of the iron core, and effectively improving the assembly accuracy.

Detailed Implementation

[0017] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Embodiments of the invention will now be described in full with reference to the accompanying drawings. It should be noted that the invention may be implemented in various forms and is not limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0019] Unless otherwise expressly defined, the use of directional terms such as "center," "lateral," "longitudinal," "horizontal," "vertical," "top," "bottom," "inner," "outer," "upper," "lower," "front," "rear," "left," "right," "clockwise," and "counterclockwise" in the claims, description, and accompanying drawings of this invention is merely for the convenience of describing the invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the specific scope of protection of this invention.

[0020] This invention provides an assembly apparatus for rotor magnetic components, combined with Figure 1-11 As shown, it includes an assembly fixture 1, a dispensing mechanism 2, and a magnet mounting mechanism 3; combined with Figure 11 As shown, the rotor magnetic assembly 4 includes an iron core 5 and multiple rotor magnets 6. The iron core 5 is cylindrical, and the multiple rotor magnets 6 are bonded to the outer peripheral wall of the iron core 5 and arranged at intervals around the outer peripheral wall. Figure 1-4 As shown, the assembly fixture 1 is used to clamp and fix the iron core 5. On the assembly fixture 1, corresponding to the bonding position of each rotor magnet 6 on the iron core 5, a guide channel 7 is provided. After the iron core 5 is clamped into the assembly fixture 1, each guide channel 7 extends radially from the outside towards the outer peripheral wall of the iron core 5. Each guide channel 7 corresponds to the installation position of one rotor magnet 6 on the iron core 5, and the size of each guide channel 7 allows one rotor magnet 6 to pass through. Through this guide channel 7, each rotor magnet 6 is constrained by the position of the inner wall of the channel when pushed in, forcibly limiting its position and eliminating misalignment, tilting, or displacement caused by the magnet's own attraction or manual alignment deviation, significantly improving the placement accuracy of multiple magnets on the outer peripheral wall of the iron core. Combined with... Figure 7 As shown, the dispensing mechanism 2 is used to dispense adhesive onto the outer peripheral wall of the iron core 5; combined with Figure 8-10 As shown, the magnet mounting mechanism 3 is used to push the rotor magnet 6 along each guide channel 7 to the outer peripheral wall of the iron core 5, so that the rotor magnet 6 is bonded to the surface of the iron core 5. Of course, those skilled in the art will understand that the dispensing mechanism 2 should first apply adhesive to the bonding position on the outer peripheral wall of the iron core 5, and then the magnet mounting mechanism 3 pushes the magnet along the guide channel 7. This scheme also ensures that the magnet and the adhesive layer are pressed perpendicularly without scratching, thus improving the bonding reliability. As for the specific structure of the dispensing mechanism 2 and the magnet mounting mechanism 3, those skilled in the art can use existing dispensing robots and magnet loading robots to achieve the above-mentioned corresponding functions. A preferred structure of the dispensing robot and the magnet loading robot is given later.

[0021] In a preferred embodiment, the assembly fixture 1 includes a clamping assembly 8 and a positioning seat 9; the clamping assembly 8 is used to clamp and fix the iron core 5; the positioning seat 9 is detachably installed on the clamping assembly 8, and each guide channel 7 is provided on the positioning seat 9. Integrating the guide channels 7 into the detachable positioning seat 9 facilitates quick replacement according to different magnet specifications, improves the versatility of the device, and allows the positioning seat 9 to be omitted during dispensing, thus making way for the dispensing process. More preferably, the clamping assembly 8 includes a fixture base 10 and a pressure cap 11; the fixture base 10 has a columnar portion 12, one end of which has a radially protruding flange 13, the columnar portion 12 is used for housing the iron core 5, and the flange 13 is used to abut against one axial end of the iron core 5 to limit the position of the iron core 5 in the axial direction of the columnar portion 12; the pressure cap 11 is detachably installed on the fixture base 10, and after installation, it elastically abuts against the other axial end of the iron core 5, so that the iron core 5 is clamped between the pressure cap 11 and the flange 13; the positioning seat 9 is used to fit onto the outer ring of the iron core 5 on the fixture base 10, and after fitting, it forms a circumferential snap-fit ​​positioning with the fixture base 10, thereby ensuring that the circumferential direction of the guide channel 7 and the bonding position of the outer peripheral wall of the iron core 5 corresponds one-to-one. Preferably, the pressure cap 11 is installed on the fixture base 10 by a locking device, which includes a locking rod 14 and a compression spring 15. The locking rod 14 axially penetrates the pressure cap 11, with an operating handle 16 at one end and a locking pin 17 protruding radially at the other end. A locking pin hole 18 is formed on the fixture base 10. A radially outwardly extending groove 19 is provided on the side wall of the locking pin hole 18. The groove 19 includes an axial groove section 20 extending axially along the locking pin hole 18 and a circumferential groove section 21 extending circumferentially along the locking pin hole 18. The axial groove section 20 extends to the opening end of the locking pin hole 18. The locking pin 17 is inserted into the locking pin hole 18 through the axial groove section 20 and is engaged in the circumferential groove section 21 after the locking rod 14 is rotated. The compression spring 15 is compressed and elastically pressed between the operating handle 16 and the pressure cap 11 to press the pressure cap 11 against the iron core 5 after installation. This locking device enables quick assembly and disassembly of the iron core and provides elastic clamping of the iron core.

[0022] The dispensing mechanism 2 includes a fixture rotation mechanism 22, a dispensing head 23, and a dispensing head driving mechanism 24. The fixture rotation mechanism 22 is used to place the clamping assembly 8, and after placement, it drives the clamping assembly 8 to rotate around the axis of the iron core 5 on it. The dispensing head 23 is used to dispense adhesive. The dispensing head driving mechanism 24 drives the dispensing head 23 to move to the fixture rotation mechanism 22, so that the dispensing outlet of the dispensing head 23 is aligned with the outer peripheral wall of the iron core 5 on the clamping assembly 8 placed on the fixture rotation mechanism 22. By rotating the iron core 5 through the fixture rotation mechanism 22, combined with the movement of the dispensing head 23, adhesive can be evenly applied to each magnet bonding position. More specifically, the jig rotation mechanism 22 includes a placement seat 25, a rotary motor 26, and a connector 27. The placement seat 25 forms a placement groove 28 for inserting the clamping assembly 8. After insertion, the outer peripheral wall of the clamping assembly 8 engages with the inner sidewall of the placement groove 28, allowing the clamping assembly 8 to rotate within the placement groove 28. The axis of rotation is the axis of the iron core 5. Specifically, the placement groove 28 is an upward-opening arc-shaped groove that matches the circular sidewall contour of the clamping assembly 8. The clamping assembly 8 is placed horizontally in the placement slot 28. The connector 27 is located at one end of the placement slot 28. One end of the connector 27 has a protrusion 29, and the other end has a groove 30. After the clamping assembly 8 is placed into the placement slot 28, the protrusion 29 slides into the groove 30, so that the connector 27 and the clamping assembly 8 form a circumferential engagement. A rotary motor 26 is connected to the connector 27 to drive the connector 27 to rotate, thereby driving the clamping assembly 8 to rotate within the placement slot 28. This structure achieves rapid positioning and reliable synchronous rotation of the clamping assembly 8.

[0023] The magnet mounting mechanism 3 includes a turntable 31 and a magnet pushing device 32. The turntable 31 is used to place the assembly fixture 1, driving the assembly fixture 1 to rotate around the axis of the iron core 5. Those skilled in the art will understand that the turntable 31 is driven by a motor. The magnet pushing device 32 is located around the turntable 31, allowing the assembly fixture 1 to push the rotor magnet 6 towards the turntable 31. During the rotation of the turntable 31 carrying the assembly fixture 1, each guide channel 7 is aligned with the direction of the rotor magnet 6 pushed out by the magnet pushing device 32, allowing the rotor magnet 6 to pass through the guide channels 7 and reach the outer peripheral wall of the iron core 5. Through the rotation of the turntable 31 and the sequential action of the magnet pushing device 32, the installation of all magnets is automatically completed. Furthermore, two magnet pushing devices 32 are provided, each pushing out a rotor magnet 6 with different polarities, automatically achieving alternating bonding of the N and S poles, meeting the requirement of alternating rotor magnet polarity arrangement, and improving assembly efficiency. A more preferred magnet mounting mechanism 3 is as follows: it includes a magnet clamp 33, a feeding rod 34, and a push rod 35. The magnet clamp 33 allows a row of rotor magnets 6 to enter, and the rotor magnets 6 attract each other within the magnet clamp 33. The feeding rod 34 is located at one end of the row of rotor magnets 6 within the magnet clamp 33. A clamping magnet 36 is provided at one end of the magnet clamp 33. The clamping magnet 36 moves the row of rotor magnets 6 upwards to the feeding rod 34 through magnetic force. The feeding rod 34 is movably configured, and its direction of movement is perpendicular to the arrangement direction of the row of rotor magnets 6. It can insert a row of rotor magnets 6 and push one rotor magnet 6 at its end out of the magnet clamp 33 to the front end of the push rod 35. A push rod magnet 37 is provided on the push rod 35. The push rod magnet 37 is used to attract the rotor magnet 6 located at the front end of the push rod 35. The push rod 35 is used to push the rotor magnet 6 at its front end into the guide channel 7 it faces.

[0024] The present invention also provides a method for assembling a rotor magnetic assembly using the above-mentioned assembly device, comprising the following steps: Step 1, clamping the iron core 5 using the clamping assembly 8; Step 2, placing the clamping assembly 8 into the jig rotation mechanism 22, rotating the clamping assembly 8 using the jig rotation mechanism 22, and applying adhesive to the rotor magnet bonding position on the outer periphery of the iron core 5 using the dispensing head 23; Step 3, after the adhesive is applied, removing the clamping assembly 8 from the jig rotation mechanism 22, installing the positioning seat 9 onto the clamping assembly 8, and then placing the clamping assembly 8 with the positioning seat 9 installed onto the turntable 31; Step 4, rotating the positioning seat 9 using the turntable 31, and pushing the rotor magnet 6 of the corresponding polarity through the corresponding guide channel 7 to the outer periphery of the iron core 5 using the two magnet pushing devices 32, so that the rotor magnet 6 is bonded to the outer periphery of the iron core 5; Step 5, removing the iron core 5 with the rotor magnet 6 bonded to it from the clamping assembly 8. In this method, the positioning seat 9 does not need to block the dispensing, which facilitates the operation of the dispensing head 23. When the magnet is installed, the positioning seat 9 is attached, and the guide channel 7 is used to achieve precise pushing. Both share the same clamping reference, which ensures the accuracy of process connection. The rotation of the turntable 31 causes each guide channel 7 to be aligned with the magnet pushing device 32 in sequence. The two pushing devices with different polarities can automatically supply magnets alternately to achieve N / S pole alternating installation, and finally complete the high-precision assembly of the rotor magnetic assembly.

[0025] Of course, those skilled in the art should know that the various actions described in this embodiment can be driven by a motor, telescopic cylinder, linear motor, or other power source. Those skilled in the art can set them as needed, and these can all be achieved using conventional techniques in the field.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the design of this case. All equivalent changes made based on the key design features of this case shall fall within the protection scope of this case.
