Description

Technical Field

[0001] This invention belongs to the field of new energy vehicle technology, and relates to the assembly of rotor magnets for new energy vehicle motors, specifically to a flexible assembly system and method for rotor magnets in new energy vehicle motors. Background Technology

[0002] As the global automotive industry transitions to electrification, the performance, efficiency, and reliability of drive motors for new energy vehicles have become core competitive advantages. Rotor magnet assembly, a crucial process in the manufacturing of permanent magnet synchronous motors, directly impacts the motor's electromagnetic performance, efficiency, and reliability.

[0003] Currently, most new energy motor rotor magnet assembly equipment is designed as rigid, specialized machines, capable of assembling only specific magnets for a single motor model, such as rectangular or tile-shaped magnets of fixed dimensions and rotors with a fixed number of poles. When products are updated or multiple motor models need to be produced, cumbersome changes to mechanical tooling, adjustments to mechanical structures, or equipment modifications are necessary. This results in long production changeover and debugging cycles, high costs, and an inability to meet the rapidly evolving market demands of new energy vehicle motors. Furthermore, magnet polarity identification and assembly positioning largely rely on manual intervention, making incorrect or missing magnets prone to occur.

[0004] Therefore, there is an urgent need for a highly flexible, high-precision, high-efficiency, and highly integrated rotor magnet assembly system to enable efficient, precise, and reliable automated assembly of rotor magnets for various specifications of new energy vehicle motors. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the purpose of this invention is to provide a flexible assembly system and method for rotor magnets of new energy vehicle motors. This invention can be applied to the automated assembly of rotor magnets of new energy vehicle motors of various specifications, and has high assembly efficiency and high precision.

[0006] The technical solution of this invention is implemented as follows:

[0007] A flexible assembly system for rotor magnets of a new energy vehicle motor includes a control unit and a workbench, as well as a feeding unit, a pushing unit, an assembly unit and a positioning unit disposed on the workbench.

[0008] The feeding unit is used to store and orderly supply magnets.

[0009] The pushing unit is located between the supply unit and the assembly unit. It is used to receive the single magnet output by the supply unit and push it horizontally to the assembly preparation position located below the assembly unit.

[0010] The displacement unit is located below the assembly unit and is used to support the rotor core and drive the rotor core to move and rotate horizontally, so as to position the target core slot of the rotor core to the assembly execution position.

[0011] The assembly unit is used to vertically press the magnet into the target core slot of the rotor core.

[0012] The control unit is communicatively connected to the feeding unit, pushing unit, assembly unit, and positioning unit, which facilitates controlling the pushing unit to push the magnets to the assembly preparation position and controlling the positioning unit to move the target core slot of the rotor core to the assembly execution position, and triggering the assembly unit to perform pressing, and then rotating the rotor core to the next target core slot until the assembly of all magnets of the rotor core is completed.

[0013] Furthermore, the feeding unit includes a first support frame, a bearing plate, and a lifting mechanism. The bearing plate is vertically and vertically mounted on the first support frame via the lifting mechanism, and at least one magazine assembly is provided on the bearing plate.

[0014] The magazine assembly includes a magazine, a guide rail, and a mechanical lock; the magazine is horizontally arranged for storing multiple magnets in layers; the guide rail is located inside the magazine for guiding the movement of the magnets; the mechanical lock is located at the outlet of the magazine to control the release of the magnets; and an unlocking component adapted to the mechanical lock is provided on the first support frame to control the opening and closing of the mechanical lock.

[0015] Furthermore, there are multiple magazine assemblies, all of which are arranged vertically and detachably on the support plate, making it easy to adapt to magnets of different sizes by replacing magazine assemblies with magazines of different specifications.

[0016] Furthermore, the pushing unit includes a bracket, a pushing cylinder, a first magnetic pusher block, and a support platform located between the material outlet of the feeding unit and the assembly preparation position.

[0017] The upper surface of the support platform is flush with the lower edge of the magazine assembly outlet, and is used to receive the single magnet output by the feeding unit; the bracket is fixed on the workbench, the pusher cylinder is horizontally set on the bracket, and the output end of the pusher cylinder is connected to the first magnet pusher block to drive the first magnet pusher block to reciprocate horizontally, thereby pushing the single magnet located at the outlet of the hopper horizontally to the assembly preparation position.

[0018] Furthermore, the assembly unit includes a second support frame, a drive mechanism, and a second magnet pusher block; the second support frame is mounted above the workbench via a horizontally arranged support platform; the second magnet pusher block is vertically mounted on the second support frame via the drive mechanism to press the magnet in the assembly preparation position into the target core slot of the rotor core.

[0019] Furthermore, the assembly unit also includes a detection mechanism located near the assembly preparation position. The detection mechanism is used to detect the polarity of the magnet to be assembled. The detection mechanism is signal-connected to the control unit to feed back the detection result to the control unit to control the operation of the assembly unit.

[0020] Furthermore, the displacement unit includes a horizontal moving mechanism, a rotating mechanism, and a horizontal platform; the horizontal moving mechanism is disposed on the worktable; the rotating mechanism is disposed on the horizontal moving mechanism and is driven by the horizontal moving mechanism to move horizontally; the horizontal platform is detachably mounted on the rotating mechanism and is driven by the rotating mechanism to rotate; the horizontal platform is used to support and clamp the rotor core.

[0021] This invention also provides a flexible assembly method for rotor magnets in new energy vehicle motors, specifically including the following steps:

[0022] (1) Clamp the rotor core to be assembled onto the displacement unit;

[0023] (2) Control the feeding unit and the pushing unit to work together to push a single magnet to the assembly preparation position, and use the detection mechanism to detect the polarity of the magnet;

[0024] (3) If the magnet polarity is detected to be correct, control the displacement unit to position the target core slot of the rotor core to the assembly execution position;

[0025] (4) Control the assembly unit to press the magnet in the assembly preparation position vertically into the target iron core slot;

[0026] (5) Determine whether all magnets of the current rotor core have been assembled. If not, control the displacement unit to move to the next target core slot and return to step (2); if completed, end the current rotor core assembly process.

[0027] Furthermore, in step (2), if the testing agency detects an error in the polarity of the magnet, it will suspend the process and issue an alarm, or remove the magnet and refeed it.

[0028] Furthermore, before step (1), the process includes: replacing the corresponding specification of the clip assembly in the feeding unit according to the size of the magnet to be assembled; replacing the corresponding horizontal platform on the displacement unit according to the size and slot type of the rotor core to be assembled, and selecting or inputting the corresponding assembly program in the control unit.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The feeding unit of this invention adopts a structure that combines a multi-clamp array with a lifting mechanism. Multiple detachable clamp assemblies are arranged vertically on the support plate, and the inner cavity size of each clamp assembly matches the outer dimensions of the magnet. When different models of products need to be produced, clamp assemblies with different specifications of hoppers are replaced. Simultaneously, the horizontal platform of the displacement unit is also a replaceable modular tooling; different specifications of horizontal platforms can be used for rotor cores of different specifications. Thus, the assembly system described in this invention is applicable to the assembly of magnets for rotor cores of various specifications of new energy vehicle motors, exhibiting high flexibility.

[0031] 2. The magnets of the present invention are fed through two stages: gravity release and horizontal pushing. Each magazine assembly stores multiple magnets, which can meet the needs of continuous production. When the magnets in one magazine assembly are exhausted, the feed can be switched to another magazine assembly. Operators can replenish empty magazine assemblies, realizing material change without stopping the machine and high-speed continuous production, thereby effectively improving assembly efficiency.

[0032] 3. This invention uses a testing mechanism to detect the polarity of each magnet to be assembled, fundamentally eliminating the quality problem of incorrect magnet polarity assembly and ensuring the assembly quality of the magnets. Simultaneously, through the coordinated action of the feeding unit, pushing unit, assembly unit, positioning unit, and control unit, this invention achieves a product qualification rate of over 99.9%.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0042] It should be noted that similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures, or the orientation or positional relationship commonly used when the product is in use. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. In addition, the terms "horizontal," "vertical," etc., do not indicate that the component is required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted. In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] Because the assembly equipment for rotor magnets in new energy motors is mostly designed as rigid, specialized machines, it can only handle specific magnets for a single motor model, such as rectangular or tile-shaped magnets of fixed dimensions and rotors with a fixed number of poles. When products are updated or multiple motor models need to be produced, cumbersome changes to mechanical tooling, adjustments to mechanical structures, or equipment modifications are necessary. This results in long production changeover and debugging cycles, high costs, and an inability to meet the rapidly evolving market demands of new energy vehicle motors. Furthermore, magnet polarity identification and assembly positioning largely rely on manual intervention, making incorrect or missing installations prone to occur.

[0044] Based on this, the present invention provides a flexible assembly system for rotor magnets in new energy vehicle motors, aiming to achieve high efficiency, high quality, and high flexibility in magnet assembly. See also... Figures 1-7 The system mainly includes a control unit, a workbench A00, and four functional units located on the workbench: a feeding unit A01, a pushing unit A02, an assembly unit A03, and a displacement unit A04.

[0045] The workbench A00 is a rigid platform, typically a steel frame structure, with a precision-machined upper surface that provides a high degree of flatness and rigidity to offer a precise mounting base for the four functional units.

[0046] The feeding unit A01 is responsible for the storage and orderly supply of magnets and is fixed to the workbench surface by bolts. The displacement unit A04 is located below the assembly unit A03. The pushing unit A02 is located between the feeding unit A01 and the assembly unit A03. All units are communicatively connected to the control unit (usually a PLC or industrial computer), receiving its instructions and feeding back status information.

[0047] The core workflow is coordinated by the control unit: First, the feeding unit A01 delivers a magnet to the discharge port, and the pushing unit A02 pushes it horizontally to the assembly preparation position directly below the assembly unit A03. Simultaneously, the positioning unit A04 moves and rotates the clamped rotor core, precisely aligning the target core slot on the rotor core with the assembly execution position (coaxial with the assembly preparation position). Next, the assembly unit A03 moves downwards to press in the magnet. After each magnet is assembled, the positioning unit A04 rotates the rotor core to the next target core slot, repeating the cycle until all magnets are assembled.

[0048] (1) Feeding unit

[0049] See Figure 4 The feeding unit A01 is one of the key modules for achieving flexibility in the assembly system. The feeding unit includes:

[0050] First support frame: The support frame includes a vertically arranged upright plate 11, the lower end of which is fixed to the workbench. A reinforcing plate 12 is provided on one side of the upright plate 11 to reinforce the upright plate 11 and improve the structural stability of the first support frame.

[0051] Support plate 15: The support plate 15 is located on the other side of the upright plate 11 and is used to install the magazine assembly. Two sliders are vertically arranged on the other side of the upright plate 11. Correspondingly, the support plate 15 is provided with a sliding groove that cooperates with the sliders, so that the support plate can move vertically along the sliders under the action of the lifting mechanism. Multiple magazine assemblies 14 are detachably installed on the support plate. Each magazine assembly 14 is horizontally arranged, and all magazine assemblies 14 are arranged side by side vertically. By replacing magazine assemblies of different specifications, different sizes of magnets can be adapted.

[0052] Lifting mechanism: includes servo motor 13 and transmission screw; servo motor 13 is fixed above the upright plate 11 by motor base, the transmission screw is vertically set and the upper end of the transmission screw is connected to the output end of servo motor 13, the middle and lower part of the transmission screw is connected to the support plate 15 to drive the support plate to lift and lower. When servo motor 13 drives transmission screw to rotate, it can drive the support plate 15 to lift and lower vertically, thereby driving multiple clip assemblies 14 installed on the support plate 15 to move up and down, so that the discharge ports of clip assemblies 14 at different heights are aligned with the pushing path of the pushing unit A02 in sequence.

[0053] Magazine Assembly 14: Each magazine assembly includes a horizontally positioned hopper with a guide rail inside for guiding the movement of the magnets; the hopper can store dozens of magnets stacked together. A mechanical lock is provided at the outlet of the hopper to control the release of the magnets; simultaneously, an unlocking component adapted to the mechanical lock is provided on the first support frame to control the opening and closing of the mechanical lock. The unlocking component is fixedly mounted on the first support frame and can be adapted to the mechanical locks of all magazine assemblies on the support plate. In this embodiment, the unlocking component consists of a drive cylinder and an unlocking hook. When replenishment or replacement is required, the drive cylinder drives the unlocking hook to open the mechanical lock. At this time, the entire magazine assembly 13 can be pulled out along the hopper rail 132 for replacement, or manual replenishment can be performed, making the operation safe and convenient. In this embodiment, the mechanical lock consists of a locking tongue, a return spring, and a rotating shaft. The locking tongue extends under the action of the spring to block the magnets and prevent them from slipping out. The tail of the locking tongue has a groove adapted to the unlocking hook. When the drive cylinder extends, the unlocking hook moves forward, hooks the locking tongue, and pulls it to rotate, thus unlocking the device. When the drive cylinder retracts, the unlocking hook disengages, and the locking tongue resets and locks under the action of the spring.

[0054] During magnet assembly, the lifting mechanism moves the target magazine assembly to the pushing height according to control commands. Once the target magazine assembly is in place, the drive cylinder of the unlocking component extends, opening the discharge port. At this time, the magnet falls onto the support platform 24 of the discharge port under gravity. This support platform 24 is flush with the bottom surface of the first magnet pusher block of the pushing unit A02. After pushing is completed, the drive cylinder of the unlocking component retracts, and the locking tongue resets.

[0055] (2) Pushing unit

[0056] See Figure 5 The feeding unit A02 includes a bracket 21, a feeding cylinder 23, a first magnet pusher block 22, and a support platform 24 located between the feeding unit outlet and the assembly preparation position. The upper surface of the support platform 24 is flush with the lower edge of the magazine assembly outlet, and it receives single magnets output by the feeding unit A01. The bracket 21 is a portal frame made of welded square steel tubing, and its bottom is bolted to the workbench surface. The feeding cylinder 23 can be a double-guide-rod cylinder, which has two built-in guide rods. The first magnet pusher block 22 consists of a sliding block and a pushing block; the sliding block is connected to the feeding cylinder, and the pushing block is connected to the sliding block, used to push the magnets. A support platform is provided between the feeding unit outlet and the assembly preparation position.

[0057] After the magnet falls from the hopper outlet onto the support platform, the control unit controls the pusher cylinder to move, which in turn controls the first magnet pusher block to move smoothly forward, pushing the magnet along the support platform to the assembly preparation position. After it is pushed into place, the pusher cylinder moves to reset the first magnet pusher block.

[0058] (3) Assembly unit

[0059] Assembly unit A03 is positioned above the workbench via a horizontally arranged support platform 35, which is connected to a bracket. Assembly unit A03 includes a second support frame 32, a drive mechanism 33, and a second magnet pusher block 31. The second support frame 32 is positioned on the support platform 35. The second magnet pusher block 32 is vertically and vertically positioned on the second support frame 32 via the drive mechanism 33 to press the magnet in the assembly preparation position into the target core slot of the rotor core.

[0060] The second support frame 32 is fixed to the support platform 35 by bolts. In this embodiment, the drive mechanism can be a high-precision servo electric cylinder with controllable position, adjustable pressure, and smooth movement. The drive mechanism is installed vertically downwards, and the second magnet pusher is installed at the output end of the drive mechanism. To ensure assembly quality, a detection mechanism is installed near the assembly preparation position to detect the direction of the magnetic field of the magnet to be assembled, identify whether it is the N pole or the S pole, and feed the detection result back to the control unit in real time to control the action of the assembly unit. The detection mechanism here can use non-contact magnetic detection elements such as Hall sensors or magnetoresistive sensors.

[0061] During assembly, the control unit judges the detection results according to the preset assembly requirements (such as whether the iron core slot should be equipped with N-pole magnets or S-pole magnets). If the polarity is correct, the control unit continues to press-fit; if the polarity is incorrect, the process is paused and an alarm is triggered, or the magnet is removed and re-fed.

[0062] (4) Displacement unit

[0063] The displacement unit A04 is the core component for achieving precise positioning and multi-angle assembly of the rotor core. It includes a horizontal moving mechanism 41, a rotating mechanism 42, and a horizontal platform 43. The horizontal moving mechanism 41 is mounted on the worktable. The rotating mechanism 42 is mounted on the horizontal moving mechanism 41 and is driven by the horizontal moving mechanism 41 to move horizontally. The horizontal platform 43 is detachably mounted on the rotating mechanism 42 and is driven by the rotating mechanism 42 to rotate. The horizontal platform 43 is used to support and clamp the rotor core.

[0064] The horizontal moving mechanism here employs a precision linear module, driven by a servo motor and a ball screw or synchronous belt to achieve high-precision linear motion. This horizontal moving mechanism provides the X-axis direction of movement, used to move the rotor core in the horizontal plane so that its core slots can be aligned with the assembly unit. The rotating mechanism, mounted on the horizontal moving mechanism, enables precise rotation at any angle, providing the rotor core with the freedom to rotate around its central axis. This is used to sequentially deliver the core slots at different angles to the assembly execution position. A horizontal platform, located on the rotating mechanism, is used to support and clamp the rotor core. The horizontal platform is equipped with locating pins, pressure blocks, or quick-release clamps that cooperate with the rotor core's central hole and end face positioning structure, ensuring the rotor core remains stable during high-speed movement and rotation.

[0065] Because the rotor cores of new energy vehicle motors come in various specifications—different outer diameters, different heights, and different numbers of slots (8-pole, 10-pole, 12-pole, etc.)—only a matching horizontal platform needs to be designed and manufactured for each type of rotor core. When a changeover is needed, operators simply remove the existing horizontal platform, install a platform suitable for the new rotor core, and call the corresponding assembly program (which includes parameters such as horizontal movement distance, rotation angle, and pressing position) in the human-machine interface of the control unit. This allows for a very short time to complete the changeover preparation. This is another important manifestation of flexibility.

[0066] Based on the above system, the present invention also provides a flexible assembly method for rotor magnets of new energy vehicle motors, specifically including the following steps:

[0067] (1) Replace the corresponding horizontal platform on the displacement unit according to the size and slot type of the rotor core to be assembled; replace the corresponding clip assembly on the feeding unit according to the size and specifications of the magnet to be assembled; select or input the assembly program that matches the current product model on the control unit.

[0068] (2) Place the rotor core to be assembled on a horizontal platform and clamp and fix the rotor core with positioning pins and quick clamps to ensure that the rotor core is stable during movement and rotation.

[0069] (3) The control unit controls the lifting mechanism of the feeding unit to move the outlet of the target magazine assembly to the same height as the pushing path of the pushing unit. Then the unlocking part is activated to unlock the mechanical lock of the magazine assembly. The pushing cylinder of the pushing unit is activated to drive the first magnet pusher block to push a magnet to the assembly preparation position. After the magnet is in place, the detection mechanism detects the polarity of the magnet and feeds back the detection result to the control unit.

[0070] (4) If the polarity of the magnet is detected to be correct, the synchronous control of the displacement unit is activated to position the target core slot of the rotor core to the assembly execution position. That is, the rotor core is moved to the position where the radial center line of the target core slot coincides with the axis of the assembly unit through the horizontal moving mechanism. Then, the rotation mechanism is used to position the opening of the target core slot of the rotor core slot facing the assembly unit.

[0071] (5) The control unit controls the drive mechanism of the assembly unit to move down. The second magnet pusher first contacts and grabs the magnet at the assembly preparation position, and then continues to move down, pressing the magnet smoothly and vertically into the target iron core groove at the assembly execution position. After the pressing is completed, the drive mechanism drives the second magnet pusher to reset.

[0072] (6) Determine whether all magnets of the current rotor core have been assembled. If not, control the rotation mechanism of the displacement unit to rotate, drive the rotor core to the next target core slot, return to step (3), and assemble the next magnet. If completed, end the current rotor core assembly process, and the operator can unload the finished product and assemble a new rotor core.

[0073] In specific implementation, in step (3), if the detection mechanism detects that the polarity of the magnet is misaligned, the system will stop running, issue an audible and visual alarm, and display an error message, waiting for the operator to handle it manually; or the control unit will control the pushing unit to push the magnet into the waste box, and control the feeding unit and pushing unit to resupply a new magnet and perform polarity detection.

[0074] Finally, it should be noted that the above embodiments of the present invention are merely illustrative examples and not intended to limit the implementation of the invention. Those skilled in the art can make other variations and modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this invention are still within the scope of protection of this invention.
