Rotor magnet assembly apparatus and method

Abstract

This invention discloses a rotor magnet assembly equipment and method, which addresses the challenge of assembling high-density, alternating-pole magnets. The equipment mainly comprises multiple parallel pre-assembly units and a horizontal transfer mechanism. Each pre-assembly unit is equipped with a feeding, horizontal pushing, attitude adjustment, and pressing mechanism, used to accurately press the magnet strips one by one into a local array on a physically isolated magnet pre-assembly mold. The horizontal transfer mechanism is used to pick up the pre-assembled complete cylindrical magnet group and press it into the mounting groove on the outer wall of the rotor synchronously. This method first completes the precise arrangement and pre-fixation of all magnets in a magnetically interference-free environment at the pre-assembly station, and then completes the final assembly in one go through overall transfer and pressing. This effectively avoids magnetic interference caused by the different magnetic poles of adjacent magnets during pressing, eliminates magnet breakage and rotor scratches, and significantly improves the assembly cycle time.

Description

Technical Field

[0001] This invention relates to the field of automated processing equipment technology, and in particular to a rotor magnet assembly equipment and method. Background Technology

[0002] With the rapid development of new energy vehicles, industrial automation, and high-end home appliances, the market demand for high-performance motors is increasing, placing higher demands on the manufacturing precision and production efficiency of motors. The assembly of the motor rotor and magnets is one of the core processes in motor manufacturing, and its assembly quality directly affects the magnetic circuit stability, operational reliability, and overall performance of the motor.

[0003] Currently, in the field of permanent magnet motor manufacturing, especially for high-performance motors using surface-mount or embedded magnet structures, magnet assembly methods are mainly divided into manual assembly and semi-automatic mechanical pressing. For small-batch production or products with a small number of magnets, manual assembly is still used due to its flexibility, but it suffers from problems such as high labor intensity, poor assembly consistency, and difficulty in guaranteeing positioning accuracy. For mass-produced permanent magnet motors, the industry has developed various automated pressing equipment. For example, some existing technical solutions can achieve automated magnet feeding and pressing by setting up magnet feeding mechanisms, pressing mechanisms, and positioning seats, which improves assembly efficiency to a certain extent. Other equipment uses cross-shaped slide rails or vertical pressing mechanisms to ensure stability during the pressing process.

[0004] However, existing technologies still face significant challenges when assembling a specific high-power-density motor rotor. The rotor of this type of motor requires up to 64 magnets to be tightly fitted to its outer wall, and to meet electromagnetic performance design requirements, the magnetic poles (N / S poles) of adjacent magnets are alternately arranged, with the circumferential sides of the magnets pressed tightly against each other. This high-density, high-pole, alternating magnetic pole layout presents two core challenges for automated assembly: First, because magnets have extremely strong magnetism and the magnetic poles of magnets at adjacent workstations are opposite, if a multi-station synchronous pressing or multiple magnets are pushed in at the same time is adopted, the strong magnetic attraction or repulsion will cause the magnets to shift, flip or even collide with each other at the moment of pressing, which can easily cause the edges and corners of the magnets to crack or the inner wall of the rotor to be scratched, resulting in a high scrap rate.

[0005] Secondly, the industry currently mostly uses a single-station, one-by-one pressing process. This involves using a complex positioning mechanism at one station to press the magnets sequentially into their corresponding slots. However, for such a large quantity as 64 pieces, the cycle time for single-station sequential pressing is too long, making it difficult to meet the efficiency requirements of large-scale production. Simply increasing the number of pressing heads to attempt parallel operation would drastically increase the risk of physical damage due to magnetic pole crossover.

[0006] It is evident that existing technologies fall short in achieving automated assembly that simultaneously protects the integrity of the magnets and ensures high output, particularly under complex conditions involving 64 ultra-high-density magnets with adjacent poles of opposite polarity. Therefore, the industry urgently needs a new type of dedicated assembly equipment capable of adapting to high-density alternating magnetic pole assembly while maintaining low loss and high cycle time. Summary of the Invention

[0007] The purpose of this invention is to provide a rotor magnet assembly device and method to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a rotor magnet assembly device, comprising: including: The feeding mechanism has multiple feeding stations arranged longitudinally and capable of synchronous lifting and lowering, and is configured to push the magnetic strips arranged in a straight line at the feeding stations forward in sequence to discharge the material.

[0011] The rotor magnet assembly equipment of the present invention includes a horizontal pushing mechanism comprising a second push rod disposed on the front side of the magnetic strip guide trough plate in the left-right direction, and a first linear drive module for driving the second push rod forward or backward.

[0012] The rotor magnet assembly equipment of the present invention includes a posture adjustment mechanism comprising a rotating disk vertically disposed on the forward side of the second push rod, and a rotation drive for driving the rotating disk to rotate longitudinally along a fixed axis; a guide channel for guiding and limiting the magnetic strip is radially provided on the peripheral sidewall of the rotating disk, and at least two guide channels are provided and they are coplanar and intersecting each other.

[0013] The rotor magnet assembly equipment of the present invention includes a magnet pressing mechanism comprising a third push rod vertically disposed above the rotating disk, and a second lifting drive module for driving the third push rod to move up and down coaxially; the third push rod is located on the rotation surface of the guide channel and is coplanar with it.

[0014] The rotor magnet assembly equipment of the present invention includes a magnet transport mechanism comprising a horizontally mounted mounting plate, a rotating positioning seat horizontally rotatably mounted on the mounting plate, a magnet pre-assembly bottom mold arranged in an annular shape on the upper end of the rotating positioning seat, a rotary drive module for driving the rotating positioning seat to rotate, and a two-axis transverse movement module for driving the mounting plate to move back and forth or left and right; the upper surface of the rotating positioning seat is coaxially provided with a positioning groove for positioning the magnet pre-assembly bottom mold, and the magnet pre-assembly bottom mold is vertically provided with a slot adapted to the magnetic strip.

[0015] The rotor magnet assembly equipment of the present invention includes a magnet pre-assembly guide mechanism comprising a movable bracket disposed on the side of the two-axis transverse module away from the magnet pressing mechanism, a horizontally disposed and annular guide bottom mold on the movable bracket, and a third lifting drive module for driving the movable bracket to move up and down; the guide bottom mold is provided with a magnetic strip guide hole longitudinally penetrating the slot.

[0016] The rotor magnet assembly equipment of the present invention includes a horizontal transfer mechanism comprising a picking module for picking up magnetic strips extending from the upper end of the guide bottom mold, a fourth lifting drive module for driving the picking module to rise and fall, and a transverse drive module for driving the fourth lifting drive module to move horizontally along the parallel direction of the plurality of pre-assembly units; the transverse drive module is located above the magnet transport mechanism on the side away from the attitude adjustment mechanism. The pickup module includes a vertically arranged magnetic guide shaft, and the outer side wall of the magnetic guide shaft has a plurality of axially opened magnetic guide grooves evenly distributed around its circumference. The pickup module also includes a bottom layer press-fit ring, a middle layer press-fit ring, and a top layer press-fit ring that are movably sleeved on the outside of the magnet guide shaft from bottom to top. The inner sidewalls of the bottom layer press-fit ring, the middle layer press-fit ring, and the top layer press-fit ring are all provided with an extension press-fit arm that extends into the magnet guide groove. The lower surface of the end of the extension press-fit arm is fixed with a vertically downward ejector pin. The pickup module also includes a press-fitting drive component that drives the bottom press-fitting ring, the middle press-fitting ring, and the top press-fitting ring to move asynchronously up and down; The pickup module also includes a limiting component for radially limiting the magnetic strip inserted into the magnetic guide groove.

[0017] Furthermore, the present invention also provides a method for implementing a rotor magnet assembly device, the method comprising the following steps: Step 1: Equipment initialization and material loading. The loading mechanism of each pre-assembly unit is controlled to move. Its first lifting drive module drives the multi-layer magnetic strip guide trough plate to rise and fall, aligning the target loading station with the discharge end. At the same time, the pushing module pushes the magnetic strip to the discharge end of the guide trough, ready for use. The magnetic steel transport mechanism moves the rotor to be assembled and precisely positions it directly below the magnetic steel pressing mechanism of the first pre-assembly unit.

[0018] Step 2: Pressing in the first side magnet. The horizontal pushing mechanism at the current workstation activates, its second push rod horizontally pushing the magnetic strip from the discharge end of the loading station into the guide channel of the rotary table of the attitude adjustment mechanism. The rotary drive rotates the rotary table 90 degrees, adjusting the horizontal magnetic strip to a vertical position. Subsequently, the third push rod of the magnet pressing mechanism moves downward, pressing the vertical magnetic strip into the corresponding assembly slot on the pre-assembly mold of the magnet carried by the magnet transport mechanism directly below it. After pressing one magnet, the rotary drive module of the magnet transport mechanism activates, driving the rotary positioning seat and rotor to rotate by a fixed angle, preparing to press the next magnet. This process is repeated until all planned magnets for assembly on this side are completed in the current pre-assembly unit.

[0019] Step 3: Shifting and changing sides After the current pre-assembly unit is assembled, the two-axis transverse module of the magnet transport mechanism moves, driving the mounting plate and the magnet pre-assembly bottom mold to move horizontally, and transferring the magnet pre-assembly bottom mold to the posture adjustment mechanism of another pre-assembly unit paired with this unit.

[0020] Step 4: Pressing in the second-side magnet. Repeat step two, where the second pre-assembly unit completes the pressing of another set of magnets into the magnet pre-assembly bottom mold. This process may also include the indexing rotation of the magnet pre-assembly bottom mold.

[0021] Step 5: Removal and Transfer After the pre-installed bottom mold of the magnets completes the initial pressing of all the magnets, the horizontal transfer mechanism is activated. Its picking module moves multiple magnet strips that are pre-installed to form a cylindrical structure to the pressing station at its discharge end and aligns them with the rotor on the same axis as it descends. This makes the lower end face of the magnet guide shaft contact the upper end face of the rotor, and the ejector pin inside contacts the upper end face of the installed magnet strip. Subsequently, according to the preset program, the picking module drives its bottom, middle and top pressing rings to move upward relative to the rotor to perform the final overall compaction and depth calibration of the magnet strips.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up multiple independent pre-assembly units, the magnetic strips are pre-assembled in an isolated manner on the pre-assembly mold of the magnets. This effectively resolves the strong magnetic attraction / repulsion forces generated by the extremely small spacing between the magnetic strips and the alternating magnetic poles during direct assembly on the rotor body, fundamentally preventing magnet misalignment, collision, and damage. A horizontal transfer mechanism presses the entire pre-assembled magnet cylinder into the rotor in one go and step by step, transforming the originally time-consuming multi-station, step-by-step pressing process into a highly efficient overall assembly action, significantly improving production cycle time. The parallel setup of multiple pre-assembly units further enhances overall efficiency, resolving the contradiction between the vulnerability of magnets under high-density assembly and the high production efficiency requirements.

[0044] Example 1 This embodiment discloses, as follows: Figures 1 to 15 The rotor magnet assembly equipment 100 shown is specifically designed for the automated pressing of high-density, alternating-pole magnets into the circumferential assembly slots of a motor rotor. This assembly equipment 100 includes: The feeding mechanism 110 has multiple feeding stations arranged longitudinally and capable of synchronous lifting and lowering, and is configured to push the magnetic strips arranged in a straight line at the feeding stations forward in sequence to discharge the material. The horizontal pushing mechanism 130 is located on one side of the discharge end of the feeding mechanism 110 and is configured to horizontally push the magnetic strip on the discharge end of the feeding station to the left or right. The attitude adjustment mechanism 140 is located on the discharge side of the horizontal push mechanism 130 and is configured to adjust the magnetic strip pushed out from the horizontal push mechanism 130 from a horizontal state to a vertical state. The magnet pressing mechanism 150 is located above the attitude adjustment mechanism 140 and is configured to push the vertical magnetic strip downwards. The magnet loading mechanism 160 is located in front of the magnet pressing mechanism 150 and is configured to transport the magnet pre-installed bottom mold 163 to the bottom of the magnet pressing mechanism 150 so that the magnetic strip can be pressed into the assembly groove on its upper surface. It is also configured to adjust the circumferential rotation angle of the magnet pre-installed bottom mold 163 during the pressing of the magnetic strip. The magnet pre-assembly guide mechanism 170 is located on the discharge side of the magnet loading mechanism 160 and is configured to drive the guide bottom mold 172 to move coaxially downward and engage with the magnet on the upper surface of the magnet pre-assembly bottom mold 163 when the magnet strip pre-assembly bottom mold moves forward to the position, so that it always remains vertically upward. The horizontal transplanting mechanism 180 is located in the direction of the magnet pre-installation guide mechanism 170 and is configured to pick up vertical magnetic strips sequentially along its feeding direction. It is also configured to press multiple magnetic strips forming a cylindrical structure vertically downward into the magnetic strip mounting groove on the outer wall of the rotor at its discharge end. The feeding mechanism 110, the horizontal pushing mechanism 130, the posture adjustment mechanism 140 and the magnet pressing mechanism 150 form a pre-assembly unit A; there are multiple pre-assembly units A, which are arranged in pairs to form a magnet assembly unit B; there are multiple magnet assembly units B, which are arranged sequentially along the material transfer direction of the horizontal transfer mechanism 180.

[0045] By setting up multiple independent pre-assembly units A, the magnetic strips are pre-assembled in an isolated manner on the pre-assembly mold 163 of the magnets. This effectively resolves the strong magnetic attraction / repulsion forces generated by the extremely small spacing between the magnetic strips and the alternating magnetic poles when directly assembled on the rotor body, fundamentally preventing magnet offset, collision, and damage. The horizontal transfer mechanism 180 presses the entire pre-assembled magnet cylinder into the rotor in one go and step by step, transforming the originally time-consuming multi-station, step-by-step pressing process into a highly efficient overall assembly action, significantly improving the production cycle time. The parallel setup of multiple pre-assembly units A further enhances overall efficiency, resolving the contradiction between the vulnerability of magnets and the high production efficiency requirements under high-density assembly.

[0046] In this embodiment, the feeding mechanism 110 includes a horizontally arranged magnetic strip guide plate 111, a first lifting drive module 112 for driving the magnetic strip guide plate 111 to rise and fall, and a pushing module 113 for pushing the magnetic strips on the magnetic strip guide plate 111 forward to the discharge point; the pushing module 113 is located at the feeding end of the magnetic strip guide plate 111; multiple magnetic strip guide plates 111 are provided and arranged longitudinally side by side, and the guide grooves 114 on the upper surface of the magnetic strip guide plate 111 form a feeding station; achieving high efficiency. The efficient and orderly batch supply of magnetic strips is achieved by setting up multiple vertically multi-layered magnetic strip guide troughs 111 that can be raised and lowered synchronously. This is equivalent to equipping each pre-assembly unit A with multiple layers of "material bins". It can realize the simultaneous preparation of magnetic strips of different specifications or the batch buffering of the same type of magnetic strips, reducing the frequency of single material feeding and providing a material basis for continuous production. The cooperation between the push module 113 and the guide trough 114 realizes the linear directional conveying of magnetic strips, providing a stable and uniform material source for subsequent workstations.

[0047] In this embodiment, the pushing module 113 includes a first push rod 1131 extending into the guide groove 114, and a linear drive unit 1132 that drives the first push rod 1131 forward or backward. By extending the first push rod 1131 into the guide groove 114 to push against the magnetic strip (the magnetic poles of adjacent magnetic strips are opposite), the pushing force is ensured to act directly and accurately on the end face of the magnetic strip, making the magnetic strip move smoothly and its position controllable. This avoids jamming or flipping during the pushing process, ensures the accuracy of the discharge position, and creates conditions for receiving materials at the next station.

[0048] In this embodiment, the horizontal pushing mechanism 130 includes a second push rod 131 disposed in the left-right direction on the front side of the magnetic strip guide trough plate 111, and a first linear drive module 132 for driving the second push rod 131 forward or backward. Through the horizontally disposed horizontal pushing mechanism 130, the magnetic strip pushed out from the end of the loading station is accurately pushed into the receiving position of the attitude adjustment mechanism 140 in the horizontal direction, realizing the reliable transfer of materials between two stations in different directions (usually the vertical direction), which is a key link in the assembly line connection.

[0049] To ensure the coaxiality of the second push rod 131 and facilitate future maintenance, a connecting bridge plate 115 parallel to the magnetic strip guide trough plate 111 is provided on the feeding side of the second push rod 131. The connecting bridge plate 115 is fixed at a fixed height position by a bracket 117. A transition guide groove 118 penetrating its front and rear ends is formed on the upper surface of the connecting bridge plate 115. When the first lifting drive module 112 drives multiple magnetic strip guide trough plates 111 to descend, the discharge end opening of each guide trough 114 can be aligned with the rear end of the transition guide groove 118, so that the magnetic strip in the guide trough 114 can enter the connecting bridge plate 115. A longitudinally arranged guide plate 119 is attached to the discharge end face of the connecting bridge plate 115. On the side wall of the guide plate 119 facing the transition guide groove 118, there is a horizontal strip groove 1191 that allows the magnetic strip to enter while maintaining its original posture. The two ends of the strip groove 1191 penetrate through the two side walls of the guide plate 119. After assembly, the end of the second push rod 131 extends into the strip groove 1191. When the foremost magnetic strip enters the strip groove 1191, the second push rod 131 moves forward to push the magnetic strip to the other end of the strip groove 1191 to await connection at the next station. This series of guiding designs ensures that the movement trajectory of the magnetic strip during the horizontal pushing process is precise and controllable.

[0050] To prevent the magnetic strip from jumping out of the transition guide groove 118, a cover plate 116 is provided above the transition guide groove 118 along its length (front-back direction) to seal its upper opening. The two ends of the cover plate 116 are longitudinally aligned with the two ends of the transition guide groove 118. When the magnetic strip moves within the transition guide groove 118, its upper and lower surfaces slide against the lower surface of the cover plate 116 and the bottom surface of the transition guide groove 118, respectively, while its two end faces slide against the side walls of the transition guide groove 118. This design ensures the stability of the magnetic strip's posture during the feeding process, avoiding deviation caused by vibration or magnetic field interference.

[0051] Furthermore, to ensure that the magnetic strip can be smoothly pushed by the second push rod 131 and accurately pushed towards the receiving port of the attitude adjustment mechanism 140, a rectangular fitting groove 1192 is provided on the side wall of the guide plate 119 away from the transition guide groove 118, facing the strip groove 1191. The long side of the rectangular fitting groove 1192 is arranged in the left and right direction, and multiple through holes 1193 communicating with the strip groove are opened in the left and right direction on its vertical bottom surface. Furthermore, the front side of the guide plate 119 has a groove that can be oriented forward or backward or away from the groove. A reciprocating powerful magnet 120 and a magnet-driven linear module 121 (specifically a cylinder) that drives the powerful magnet to move back and forth; the magnet-driven linear module 121 is fixed on the bracket 117. Before the second push rod 131 moves, the powerful magnet 120 is in the rectangular bonding groove 1192, which is used to attract and bond the magnetic strip on its rear side to the strip groove 1191. After it is in place, the second push rod 131 can smoothly push the magnetic strip into the feed port (guide channel 143) of the attitude adjustment mechanism 140.

[0052] In this embodiment, the attitude adjustment mechanism 140 includes a rotating disk 141 vertically disposed on the forward side of the second push rod 131, and a rotary drive 142 for driving the rotating disk 141 to rotate longitudinally along a fixed axis. A guide channel 143 for guiding and limiting the magnetic strip is radially provided on the peripheral wall of the rotating disk 141. At least two guide channels 143 are provided and intersect each other in a coplanar manner. By setting a rotating disk 141 with specific guide channels 143, when a horizontal magnetic strip is pushed into the guide channel 143, the rotating disk 141 is driven to rotate (e.g., 90 degrees). Gravity or channel limiting is used to automatically convert the magnetic strip from a horizontal state to a vertical state, meeting the process requirement that the magnetic strip ultimately needs to be vertically pressed into the rotor. This structure is simple and reliable in operation, occupies little space, and has high flipping accuracy.

[0053] In this embodiment, the magnet pressing mechanism 150 includes a third push rod 151 vertically positioned above the rotating disk 141, and a second lifting drive module 152 that drives the third push rod 151 to move up and down coaxially. The third push rod 151 is located on the rotating surface of the guide channel 143 and is coplanar with it. By vertically positioning the third push rod 151 above the rotating disk 141 (which has been loaded with a vertical magnet strip), the vertical magnet strip with its posture adjusted can be smoothly and vertically pressed into the slot 167 of the pre-installed magnet mold 163 below through the pressing action. This ensures the consistency of the verticality and insertion depth of the pre-installed magnet strip and is one of the core execution steps to ensure the pre-assembly accuracy.

[0054] In this embodiment, the magnet loading mechanism 160 includes a horizontally mounted mounting plate 161, a horizontally rotatable rotating positioning seat 162 mounted on the mounting plate 161, a ring-shaped magnet pre-assembly bottom mold 163 located on the upper end of the rotating positioning seat 162, a rotating drive module (not shown) for driving the rotating positioning seat 162 to rotate, and a two-axis transverse movement module 164 for driving the mounting plate 161 to move back and forth or left and right; a positioning groove 1 for positioning the magnet pre-assembly bottom mold 163 is coaxially provided on the upper surface of the rotating positioning seat 162. 66. A slot 167, adapted to the magnetic strip, is vertically inserted through the pre-assembly mold 163 of the magnet. The two-axis transverse transfer module 164 enables precise transfer of the pre-assembly mold 163 between different pre-assembly units A, allowing a single rotor to sequentially accept the pre-assembly of multiple sets of magnets. A rotary drive module (not shown) enables precise indexing rotation of the pre-assembly mold 163, allowing the magnetic strips to be pressed in according to a set angular sequence. This is crucial for achieving precise circumferential alignment of alternating magnetic poles (N / S poles). The slot 167 on the pre-assembly mold 163 provides precise positioning for individual magnetic strips.

[0055] The pre-installed base mold 163 for magnets specifically includes an upper ring body 1631, on which slots 167 for inserting magnetic strips 300 are passed through vertically on its upper surface. It also includes a lower ring body 1632 coaxially positioned below the upper ring body 1631. The lower ring body 1632 is fixed to a rotating positioning seat 162. Multiple magnetic strip upper shafts 1633 are provided on the upper surface of the lower ring body corresponding to the slots 167. In the initial state, the upper end of the magnetic strip upper shaft 1633 extends into the slot 167 and is located at its lower end. The cross-section of the magnetic strip upper shaft 1633 is consistent with the slot and the magnetic strip, allowing for frictional positioning of the magnetic strip after insertion. After being pressed out from the rotating disk, it is directly aligned with the slot 167 so that the lower end is fully inserted into the slot; in addition, a lifting shaft 1634 with a fourth lifting module (not shown) is vertically provided on the rotating shaft of the upper and lower ring bodies. The top end of the lifting shaft 1634 extends out of the upper end of the upper ring body 1632 and is horizontally fixed with a positioning arm 1635. The two ends of the positioning arm 1635 extend to the upper surface of the upper ring body 1632 and are fixedly connected to it. The fourth lifting module and the lifting shaft are provided so that when the magnet pre-installed bottom mold 163 inserts the magnet strip into the magnet pre-installed guide mechanism 170, the magnet strip will be pushed out of the slot.

[0056] In this embodiment, the pre-installed magnet guide mechanism 170 includes a movable support 171 located on the side of the two-axis transverse module 164 away from the magnet pressing mechanism 150, a horizontally arranged and annular guide bottom mold 172 on the movable support 171, and a third lifting drive module 173 that drives the movable support 171 to move up and down. The guide bottom mold 172 is cylindrical and has a magnetic strip guide hole 174 that runs longitudinally through the slot 167. When the pre-installed magnet bottom mold 163 carrying the inserted vertical magnetic strip moves out of the pressing position, the guide bottom mold 172 is driven to descend and dock with the pre-installed bottom mold, and the magnetic strip guide hole 174 on it will cover the magnetic strip from above. This is equivalent to adding a "guide sleeve" to each magnetic strip. In the subsequent transfer process, no matter how the equipment moves, it can effectively prevent the magnetic strip from tilting or deflecting due to vibration, inertia or weak magnetic interference, and ensure the geometric stability of the pre-installed magnet cylinder before transfer.

[0057] In this embodiment, the horizontal transplanting mechanism 180 includes a pickup module 181 for picking up the magnetic strip extending from the upper end of the guide bottom mold 172, a fourth lifting drive module 182 for driving the pickup module 181 to rise and fall, and a transverse drive module 183 for driving the fourth lifting drive module 182 to move horizontally along the parallel direction of multiple pre-assembly units A; the transverse drive module 183 is located above the side of the magnetic steel transport mechanism 160 away from the attitude adjustment mechanism 140.

[0058] The picking module 181 includes a vertically arranged magnetic steel guide shaft 1811. The outer side wall of the magnetic steel guide shaft 1811 has a plurality of (specifically 64) axially opened magnetic steel guide grooves 1812 evenly distributed around its outer circumference. The magnetic steel guide shaft 1811 has a cylindrical structure, and its lower end face is configured such that when the pressing operation is performed, the fourth lifting drive module 182 drives the entire mechanism to descend until the lower end face of the magnetic steel guide shaft 1811 is coaxial and tightly abuts against the upper end face of the rotor to be assembled. The outer diameter of the magnetic steel guide shaft 1811 is exactly equal to the outer diameter of the rotor to ensure that the two are coaxially positioned.

[0059] The cross-sectional shape of the magnet guide groove 1812 matches the cross-sectional shape of the magnet strip to be installed (usually rectangular), and its number is the same as the number of slots on the rotor where magnets need to be installed (64 slots). The magnet guide groove 1812 is used to provide precise circumferential and radial restraint when the magnet falls or is compressed, preventing it from deflecting.

[0060] The pickup module 181 also includes, from bottom to top, a bottom-layer press-fit ring 1813, a middle-layer press-fit ring 1814, and a top-layer press-fit ring 1815, which are movably sleeved on the outside of the magnet guide shaft 1811. These three press-fit rings are all annular components, coaxially arranged with the magnet guide shaft 1811, and can all slide independently up and down along the axial direction of the magnet guide shaft 1811. The bottom-layer press-fit ring 1813 is located at the bottom, the middle-layer press-fit ring 1814 is in the middle, and the top-layer press-fit ring 1815 is at the top. The inner walls of 1813, the middle layer pressing ring 1814, and the top layer pressing ring 1815 are all provided with extended pressing arms 18a that extend into the magnet guide groove 1812. Each extended pressing arm 18a extends into a corresponding magnet guide groove 1812. A vertically downward ejector pin 18b is fixed on the lower surface of the end of each extended pressing arm 18a (i.e., the end near the axis of the magnet guide shaft 1811). The ejector pin 18b is a slender cylinder or square column, and its lower end face is used to directly contact and push the upper end face of the magnet.

[0061] To ensure precise and vertical transmission of pressing force and prevent jamming or wobbling of the extended pressing arm during sliding, the two side walls of the extended pressing arm along the circumferential direction of the magnet guide shaft 1811 form a sliding fit with the two side walls of the magnet guide groove 1812 (i.e., clearance fit, allowing free sliding but without significant radial clearance). Simultaneously, the length of the extended pressing arm along the radial direction of the magnet guide shaft 1811 is greater than the distance from the bottom of the magnet guide groove 1812 to the axis of the guide shaft; that is, the end of the extended pressing arm extends beyond the bottom of the magnet guide groove 1812 and is closer to the axis. This allows the ejector pin fixed to its lower end to act directly near the radial mid-section of the magnet, preventing the magnet from tilting under pressure due to an excessively long lever arm.

[0062] The pickup module 181 also includes a press-fitting drive assembly 1816 that drives the bottom press-fitting ring 1813, the middle press-fitting ring 1814, and the top press-fitting ring 1815 to move asynchronously up and down. This assembly includes a first drive unit 1816b, a second drive unit 1816c, and a third drive unit 1816d. The first drive unit 1816b, the second drive unit 1816c, and the third drive unit 1816d are all precision electric cylinders or pneumatic cylinders, with their moving terminals facing vertically downwards; this is to achieve asynchronous driving of the three press-fitting rings.

[0063] This embodiment features a sophisticated transmission structure.

[0064] The upper surface of the bottom pressing ring 1813 is fixed with an upwardly extending first drive shaft 1813c, the upper surface of the middle pressing ring 1814 is fixed with an upwardly extending second drive shaft 1814c, and the upper surface of the top pressing ring 1815 is fixed with an upwardly extending third drive shaft 1815c. These drive shafts are all vertically arranged precision optical shafts that pass upward through the pressing guide cavity 1817e and extend above the mechanism.

[0065] To prevent interference between the drive shafts during movement, the middle layer press-fit ring 1814 has a first movable hole 1814d for the first drive shaft 1813c to pass through, and the top layer press-fit ring 1815 has a second movable hole 1815d for the first drive shaft 1813c to pass through and a third movable hole (not shown) for the second drive shaft 1814c to pass through. The inner walls of the first and second movable holes 1814d and 1815d slide against the side wall of the first drive shaft 1813c, and the inner wall of the second movable hole slides against the side wall of the second drive shaft 1814c. In this way, the first drive shaft 1813c can pass through the middle layer press-fit ring 1814 and the top layer press-fit ring 1815 without obstruction, the second drive shaft 1814c can pass through the top layer press-fit ring 1815 without obstruction, while the third drive shaft 1815c is only fixed to the top layer press-fit ring 1815. The three sets of drive shafts do not interfere with each other and independently control their respective press-fit rings.

[0066] The upper end of the magnetic guide shaft 1811 is fixedly attached to the lower surface of the mounting plate 184 by bolts. Through holes 185 are provided on the mounting plate 184 corresponding to the positions of the first drive shaft 1813c, the second drive shaft 1814c, and the third drive shaft 1815c, allowing them to pass through. The press-fit drive assembly 1816 is integrally mounted on the upper surface of the mounting plate 184 and is connected to the first drive shaft 1813c, the second drive shaft 1814c, and the third drive shaft 1815c respectively, driving them to move asynchronously downwards.

[0067] To improve the guiding accuracy and smoothness of the drive shafts, a guide sleeve 186 is fitted between each drive shaft (1813c, 1814c, 1815c) and the through hole 185 of the mounting plate 184. The guide sleeve 186 is fixedly mounted on the mounting plate 184. The drive shafts reciprocate linearly within the guide sleeve 186, resulting in low friction and no radial wobble.

[0068] To accommodate large-diameter rotors and ensure absolutely uniform force distribution on the press-fit rings, the specific layout of the press-fit drive assembly 1816 in this embodiment has been optimized. The press-fit drive assembly 1816 is mounted above the mounting plate 184 via a bracket 187.

[0069] In this embodiment, considering the rotor is circular, the drive shafts are arranged symmetrically. Specifically, there are two first drive shafts 1813c, two second drive shafts 1814c, and four third drive shafts 1815c. The two first drive shafts 1813c are located on the extended lines at both ends of one diameter of the magnet guide shaft 1811 (i.e., the left and right ends), and the two second drive shafts 1814c are located on the extended lines at both ends of another perpendicular diameter of the magnet guide shaft 1811 (i.e., the front and rear ends). The four third drive shafts 1815c are evenly distributed in a ring array around the magnet guide shaft 1811.

[0070] The upper ends of the two first drive shafts 1813c are connected to a horizontal first connecting plate 1816e, enabling the two first drive shafts 1813c to move in tandem. The upper ends of the two second drive shafts 1814c are connected to a horizontal second connecting plate 1816f, which is located above the first connecting plate 1816e, and their projections on the horizontal plane are perpendicular (i.e., cross-shaped) to avoid motion interference. The upper ends of the four third drive shafts 1815c are all connected to a horizontal square connecting plate 1816g.

[0071] The third drive unit 1816d is vertically downward, and its movable terminal is connected to the vertical center line of the square connecting plate 1816g. There are two first drive units 1816b, each vertically downward, with its movable terminal connected to both ends of the first connecting plate 1816e. There are two second drive units 1816c, each vertically downward, with its movable terminal connected to both ends of the second connecting plate 1816f.

[0072] The pickup module 181 also includes a limiting component 1817, used to radially limit the magnetic strip inserted into the magnet guide groove 1812 before and during pressing, preventing the magnetic strip from jumping out of the guide groove or radially deflecting due to its strong magnetism. In this embodiment, the limiting component 1817 specifically includes a positioning sleeve 1817a coaxially sleeved on the outside of the magnet guide shaft 1811. The lower end of the inner wall of the positioning sleeve 1817a is integrally provided with an inwardly protruding annular boss 1817b. The inner sidewall edge of the lower surface of the annular boss 1817b extends downward coaxially and flush with an extension guide cylinder 1817c. The inner wall of the extension guide cylinder 1817c is completely flush with the inner wall of the annular boss 1817b, and the outer diameter of the extension guide cylinder 1817c is smaller than the inner diameter of the positioning sleeve 1817a. The extension guide tube 1817c is inserted into the annular space between the magnetic guide shaft 1811 and the positioning sleeve 1817a. A narrow annular cavity is formed between the inner wall of the extension guide tube 1817c and the outer wall of the magnetic guide shaft 1811, which is the annular limiting cavity 1817d.

[0073] During the pressing operation, the lower ends of each ejector pin (1813b, 1814b, 1815b) extend downwards through the annular limiting cavity 1817d. Furthermore, the side wall of each ejector pin facing away from the center of the magnet guide shaft 1811 (i.e., the radial outer wall) slides against the outer annular side wall of the annular limiting cavity 1817d (i.e., the inner wall of the extension guide cylinder 1817c). This structure effectively provides an external support rail for each ejector pin, greatly enhancing its radial stiffness and preventing bending during the pressing of the magnet.

[0074] Furthermore, the annular space between the inner wall of the positioning sleeve 1817a and the upper part of the outer wall of the magnet guide shaft 1811 forms a press-fit guide cavity 1817e. The bottom press-fit ring 1813, the middle press-fit ring 1814, and the top press-fit ring 1815 are all longitudinally movable within this press-fit guide cavity 1817e, which provides precise radial guidance for the three press-fit rings, ensuring their coaxiality with the magnet guide shaft 1811. Simultaneously, the upper surface of the annular boss 1817b forms a stop platform 1817b1. When the bottom press-fit ring 1813 moves downwards under the action of the press-fit drive assembly 1816 until its lower surface contacts the stop platform 1817b1, the stroke of the bottom press-fit ring 1813 is precisely locked. This position corresponds to the end point of the press-fit depth of the first (bottom) magnet.

[0075] The final rotor assembly process is as follows.

[0076] Initial state: The entire mechanism is raised to its highest position by the fourth lifting drive module 182. All pressing rings are at their top dead center. The feeding mechanism 110 pre-inserts magnetic strips of different lengths into the magnetic guide grooves 1812 in groups: the first batch (bottom layer) of magnets (shortest length) is inserted into the bottom of the guide groove, the second batch (middle layer) of magnets is placed on top of the first batch, and the third batch (top layer) of magnets is placed at the top. Due to the presence of the limiting component 1817, especially the radial constraint of the annular limiting cavity 1817d and the extended guide tube 1817c, all magnets, even if they are strongly magnetic, will not jump out of the guide groove or attract and deflect each other.

[0077] When pressing begins: the fourth lifting drive module 182 drives the entire mechanism to descend, so that the lower end face of the magnet guide shaft 1811 abuts against the upper end face of the rotor.

[0078] Step 1 (Pre-installation of bottom layer magnets): The two first drive units 1816b in the press-fit drive assembly 1816 are activated, driving the bottom layer press-fit ring 1813 downwards via the first connecting plate 1816e and the first drive shaft 1813c. The four ejector pins 1813b on the bottom layer press-fit ring 1813 first contact and push downwards the first batch of magnets in the corresponding guide slots. Since the middle and top layer press-fit rings have not yet moved at this time, the magnets in the remaining guide slots, although not pushed by the ejector pins, remain stable due to the radial constraint of the limiting assembly 1817 and the support of adjacent magnets. When the lower surface of the bottom layer press-fit ring 1813 contacts the stop platform 1817b1, the first batch of magnets is precisely pressed into the deepest part of the rotor slot, completing the pre-installation.

[0079] Step 2 (Pressing in the middle layer magnets): With the bottom pressing ring 1813 stationary, the two second drive units 1816c are activated, driving the middle layer pressing ring 1814 downwards via the second connecting plate 1816f and the second drive shaft 1814c. The four ejector pins 1814b on the middle layer pressing ring 1814 (distributed within four other guide slots) begin to push the second batch of magnets downwards. At this time, since the first drive shaft 1813c passes through the first movable hole 1814d of the middle layer pressing ring 1814, their movements do not interfere with each other. The second batch of magnets is pressed into the predetermined middle layer depth.

[0080] Step 3 (Final Press-fitting of Top Layer Magnets): Finally, the third drive unit 1816d is activated, driving the top layer pressing ring 1815 downwards via the square connecting plate 1816g and four third drive shafts 1815c. The eight ejector pins 1815b on the top layer pressing ring 1815 (covering all 16 guide slots) simultaneously push the third batch of magnets in all guide slots (as well as the top of the previously pressed-in first and second batches of magnets) downwards until all magnets are completely pressed into the rotor slots, forming a complete magnet ring. During this process, the first drive shaft 1813c and the second drive shaft 1814c pass through the corresponding movable holes (1815d) on the top layer pressing ring 1815, without interfering with each other.

[0081] After pressing is completed, each drive unit is reset in reverse order, and the fourth lifting drive module 182 lifts the entire mechanism to wait for the next work cycle.

[0082] Example 2 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that this embodiment provides a specific method for assembling rotor magnets. This method fully considers the actual working conditions of magnets, alternating magnetic poles, and extremely small spacing. The steps are as follows: Step 1: Equipment initialization and material loading. The loading mechanism 110 of each pre-assembly unit A is controlled to operate, and its first lifting drive module 112 drives the multi-layer magnetic strip guide plate 111 to rise and fall, aligning the target loading station with the discharge end. At the same time, the pushing module 113 pushes the magnetic strip to the discharge end of the guide trough 114, ready for use. The magnet transport mechanism 160 moves the rotor to be assembled and precisely positions it directly below the magnet pressing mechanism 150 of the first pre-assembly unit A.

[0083] Step 2: Pressing in the first side magnet. The horizontal push mechanism 130 at the current workstation is activated, and its second push rod 131 pushes the magnetic strip at the discharge end of the loading station horizontally, sending it into the guide channel 143 of the rotating disk 141 of the attitude adjustment mechanism 140. The rotary drive 142 drives the rotating disk 141 to rotate 90 degrees, adjusting the horizontal magnetic strip to a vertical state; then, the third push rod 151 of the magnet pressing mechanism 150 moves downward, pressing the vertical magnetic strip into the corresponding assembly slot on the magnet pre-assembly bottom mold 163 carried by the magnet transport mechanism 160 directly below it; after one magnet is pressed, the rotary drive module (not shown) of the magnet transport mechanism 160 is activated, driving the rotary positioning seat 162 and the rotor to rotate by a fixed angle, preparing to press the next magnet; this process is repeated until all planned magnets are assembled on this side in the current pre-assembly unit A.

[0084] Step 3: Shifting and changing sides After the current pre-assembly unit A is assembled, the two-axis transverse module 164 of the magnet transport mechanism 160 is activated, driving the mounting plate 161 and the magnet pre-assembly bottom mold 163 to move horizontally, and transferring the magnet pre-assembly bottom mold 163 to the posture adjustment mechanism 140 of another pre-assembly unit A paired with this unit.

[0085] Step 4: Pressing in the second-side magnet. Repeat step two, where the second pre-assembly unit A completes the pressing of another set of magnets into the magnet pre-assembly base mold 163. This process may also include the indexing rotation of the magnet pre-assembly base mold 163.

[0086] Step 5: Removal and Transfer After the pre-installed bottom mold 163 completes the initial pressing of all the magnets, the horizontal transfer mechanism 180 is activated. Its picking module 181 moves the multiple magnetic strips that are pre-installed to form a cylindrical structure to the pressing station at its discharge end and aligns them with the rotor to descend, so that the lower end face of the magnet guide shaft 1811 is in contact with the upper end face of the rotor, and the ejector pin inside contacts the upper end face of the installed magnetic strip. Subsequently, according to the preset program, the picking module 181 drives its bottom, middle and top pressing rings 1813, 1814 and 1815 to move upward relative to the rotor to perform the final overall compaction and depth calibration of the magnetic strips.

At the same time, the pushing module pushes the magnetic strip to the discharge end of the guide trough, ready for use. The magnetic steel transport mechanism moves the rotor to be assembled and precisely positions it directly below the magnetic steel pressing mechanism of the first pre-assembly unit. Step 2: Pressing in the first side magnet. The horizontal push mechanism at the current workstation activates, and its second push rod pushes the magnetic strip at the discharge end of the loading station horizontally, sending it into the guide channel of the rotary disk of the attitude adjustment mechanism. The rotation drive drives the rotary disk to rotate 90 degrees, adjusting the horizontal magnetic strip to a vertical state; subsequently, the third push rod of the magnet pressing mechanism moves downward, pressing the vertical magnetic strip into the corresponding assembly slot on the pre-assembled bottom mold of the magnet carried by the magnet transport mechanism directly below it; After one magnet is pressed into place, the rotation drive module of the magnet transport mechanism is activated, driving the rotation positioning seat and the rotor to rotate by a fixed angle, in preparation for pressing into the next magnet; this process is repeated until all planned magnets are assembled on this side in the current pre-assembly unit.
