Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, and more specifically, to an assembly equipment. Background Technology

[0002] Because disc motors are axial magnetic field motors, the air gap between the stator and rotor is planar, which is significantly different from the annular air gap of traditional radial motors. For motors with multiple stator or rotor disc structures, there are two or more planar air gaps, resulting in a large axial attraction between the stator and rotor. Furthermore, high axial assembly accuracy needs to be ensured during stator and rotor assembly.

[0003] Currently, the assembly of disc motors is mainly done manually, and only one side of the stator or rotor can be assembled first, ensuring that the axial position of the stator and rotor remains unchanged before assembling the other side. Therefore, specialized tooling is needed to axially lock the stator and rotor to prevent relative axial displacement under axial suction, which would affect the uniformity of the air gap. Furthermore, the assembly process requires multiple flipping of the motor, leading to numerous steps and low assembly efficiency.

[0004] See Figure 9 As shown, there is a horizontal assembly device in the prior art for manual operation, used to assemble a double-stator disc motor, including: a rotor fixing seat 1′, a first stator fixing seat 3′, a second stator fixing seat 4′, and a drive device 7′; wherein, the rotor fixing seat 1′ is used to fix the rotor 2′; the first stator fixing seat 3′ and the second stator fixing seat 4′ are respectively located on both sides of the rotor fixing seat 1′, and are used to fix the front stator 5′ and the rear stator 6′ respectively; the drive device 7′ is used to drive the first stator fixing seat 3′ and the second stator fixing seat 4′ to move close to the rotor fixing seat 1′ at the same time, and to make the distance between the front stator 5′ and the rotor 2′ equal to the distance between the rear stator 6′ and the rotor 2′ in real time. However, this type of assembly equipment has significant defects and problems: the horizontal axial assembly method used when installing the rotor mounting base 1′ and fixing the rotor 2′ not only occupies the axial space of the rotor 2′, making assembly impossible, but also, because of the horizontal axial installation, it is impossible to ensure that the center lines of the front stator 5′, rotor 2′, and rear stator 6′ are aligned, resulting in low assembly accuracy and a high risk of quality problems. Furthermore, because the air gap between the two planes of the front stator 5′, rotor 2′, and rear stator 6′ during assembly is 1mm to 2mm, it cannot be removed from the rotor mounting base 1′ after assembly. The entire assembly process is cumbersome and inefficient. Summary of the Invention

[0039] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Although the description of the present invention will be presented in conjunction with preferred embodiments, this does not mean that the features of the invention are limited to these embodiments. On the contrary, the purpose of describing the invention in conjunction with embodiments is to cover other options or modifications that may be derived based on the claims of the present invention. To provide a deep understanding of the invention, many specific details will be included in the following description. The invention may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of the invention, some specific details will be omitted in the description.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] See Figure 1 As shown, an embodiment of the present invention provides a mounting device 00, including: a frame 1; a first mounting part 2, disposed on the frame 1, for clamping a stator 01; and a second mounting part 3, disposed on the frame 1, for clamping a rotor 02; wherein, in the height direction of the frame 1 (e.g., ... Figure 1 In the Z-direction (as shown), the second assembly part 3 is disposed opposite to the first assembly part 2, and the second assembly part 3 and the first assembly part 2 can move relative to each other so that the stator 01 and the rotor 02 enter the coaxial (e.g., Figure 1 As shown in the diagram (center axis A), the components are assembled along the height direction.

[0042] For details, see Figure 1As shown, in this embodiment, the frame 1 is a rectangular frame structure. The first assembly part 2 is horizontally arranged on the frame 1, and the second assembly part 3 is arranged above the first assembly part 2, corresponding to the first assembly part 2. That is, the second assembly part 3 and the first assembly part 2 are arranged along the height direction of the frame 1. The rotor 02 is clamped on the second assembly part 3, and the stator 01 is clamped on the first assembly part 2, so that the rotor 02 and the stator 01 form a vertical positional relationship in space. At the same time, through the relative movement between the second assembly part 3 and the first assembly part 2, the positional relationship between the rotor 02 and the stator 01 can be adjusted, so that the axis of the rotor 02 and the axis of the stator 01 are perfectly aligned in the height direction by their own gravity, ensuring that the rotor 02 and the stator 01 are in a coaxial state, which facilitates assembly, avoids the problem of axis misalignment, and improves the assembly accuracy. Meanwhile, the vertical assembly method saves space. By relying on the relative movement between the second assembly part 3 and the first assembly part 2 and the self-weight of the rotor 02 and the stator 01, the assembly of the rotor 02 and the stator 01 can be achieved, which can realize automated installation and improve assembly efficiency.

[0043] In addition, the frame 1 is also equipped with a control panel 05 and an alarm device 04. The control panel 05 is used to control the operation of the entire equipment, making it convenient for staff to operate. The alarm device 04 is located on the upper part of the frame 1 and is used to promptly sound an alarm when a fault or problem occurs, reminding staff to carry out maintenance.

[0044] It should be noted that the present invention does not limit the specific form of the relative movement between the second assembly part and the first assembly part. It can be a lateral or longitudinal movement in the horizontal plane, or a vertical movement in the height direction, or it can include both lateral and longitudinal movements in the horizontal plane and vertical movements in the height direction. As long as the relative movement between the second assembly part and the first assembly part ensures that the rotor and stator are in a coaxial state, which facilitates assembly, it is acceptable.

[0045] For details, see Figure 1-3 As shown, in this embodiment, the first assembly part 2 and the second assembly part 3 are disposed on the first slide table 10. The first slide table 10 includes a mounting plate 100 and a first sliding assembly 101. The mounting plate 100 is disposed on the frame 1 through the first sliding assembly 101, and can drive the first assembly part 2 and the second assembly part 3 along the horizontal direction (e.g., ...). Figure 3 , 4 (As shown in the X direction) Extends out from inside frame 1.

[0046] In other words, both the second mounting part 3 and the first mounting part 2 are mounted on the mounting plate 100. By driving the mounting plate 100 to move, the first mounting part 2 and the second mounting part 3 can extend horizontally from the frame 1, facilitating the clamping of the stator 01 onto the first mounting part 2 and the clamping of the rotor 02 onto the second mounting part 3. Mounting both on the same mounting plate 100 not only allows both to extend or enter simultaneously, simplifying the driving process and equipment, and achieving synchronous clamping of the rotor 02 and the stator 01, but also ensures that the second mounting part 3 and the first mounting part 2 maintain a suitable distance during relative movement, facilitating adjustment and use. The first sliding assembly 101 is a sliding guide rail, horizontally mounted on the frame 1, used to drive the movement of the mounting plate 100.

[0047] It should be noted that the present invention does not limit the specific structure of the first assembly part and the second assembly part, as long as the first assembly part can clamp the stator and the second assembly part can clamp the rotor, and the stator and rotor can be assembled in the height direction.

[0048] Further, see Figure 1-3 As shown, in this embodiment, the first assembly part 2 includes: a tray 20, disposed on the mounting plate 100, for placing the stator 01; and a clamping member 21, disposed on the tray 20, for fixing the stator 01. That is, the stator 01 is placed on the tray 20, which is provided with the clamping member 21 and a limiting member (not shown in the figure). The limiting member is used to keep the stator 01 in a centered position, and the clamping member 21 can fix the stator 01 on the tray 20, facilitating the mounting and dismounting of the stator 01. In this embodiment, the tray 20 is provided with four clamping members 21, which are clamping structures. In other embodiments, the clamping members can have other numbers and structures; this invention does not limit this, as long as the clamping members can be stably and reliably mounted on the tray.

[0049] Further, see Figure 1-3 As shown, in this embodiment, the second assembly part 3 includes: a mounting base 30, which is disposed on the mounting plate 100; and a bearing slide 31, which is disposed on the mounting base 30. The bearing slide 31 is provided with a positioning block 32 for clamping the rotor 02. The bearing slide 31 is disposed on the mounting base 30 through the second sliding assembly 11 for adjusting the horizontal position between the rotor 02 and the stator 01.

[0050] In other words, the second assembly part 3 mainly consists of a mounting base 30 and a support slide 31. The mounting base 30 is fixed to the mounting plate 100 by bolts or welding. In this embodiment, when assembling the mounting base 30, it is necessary to ensure that the center of the mounting base 30 on the positioning block 32 for clamping the rotor 02 is consistent with the center of the mounting base 30 on the first assembly part 2 for clamping the stator 01. With this arrangement, adjusting the support slide 31 in one direction is sufficient to make the rotor on the second assembly part 3 and the stator on the first assembly part 2 coaxial, which is convenient for adjustment and use. The second sliding assembly 11 includes a second sliding guide rail 110 and a second sliding drive part 111. The second sliding guide rail 110 is arranged horizontally on the mounting base 30. One end of the second sliding drive part 111 is arranged on the mounting base 30, and the other end is connected to the support slide 31 to drive the support slide 31 to move.

[0051] Therefore, in this embodiment, the relative movement between the second assembly part 3 and the first assembly part 2 is lateral within the horizontal plane (e.g., ...). Figure 1 (as shown in the Y direction) or longitudinal direction (e.g.) Figure 3 , 4 The invention does not limit the driving direction of the movement between the second assembly part 3 and the first assembly part 2 in the height direction (as shown in the X direction), and can select it according to actual needs.

[0052] See Figure 1-3 As shown, in this embodiment, there is no relative movement between the second assembly part 3 and the first assembly part 2 in the height direction. Instead, an auxiliary component is used to disengage the rotor 02, which is clamped on the second assembly part 3, from the second assembly part 3, and the rotor 02 is then assembled with the stator 01 under the drive of the auxiliary component. The present invention does not limit the specific structure of the auxiliary component; it can be reasonably selected according to actual needs. For example, it can be a robotic arm, an industrial robot, or other components, as long as it enables the rotor to disengage from the second assembly part and assemble with the stator.

[0053] In other embodiments, the rotor can be disengaged from the second assembly part and assembled with the stator by the relative movement of the second assembly part and the first assembly part in the height direction. For example, components that can move in the height direction can be provided in the mounting base and the bearing slide, so that the bearing slide can drive the rotor to move in the height direction, thereby realizing the assembly of the rotor with the stator and disengagement from the second assembly part.

[0054] For details, see Figure 1 and combined Figure 6-8As shown, in this embodiment, the frame 1 is also provided with a lower ejector assembly 6 and an upper ejector assembly 5. The lower ejector assembly 6 can abut against the lower end of the rotor 02 to lift the rotor 02, and the upper ejector assembly 5 can abut against the upper end of the rotor 02 to make the rotor 02 leave the second assembly part 3.

[0055] In other words, with the assistance of the lower ejector assembly 6 and the upper ejector assembly 5, the rotor 02 can be disengaged from the second assembly part 3 and assembled with the stator 01. Specifically, the lower ejector assembly 6 can move upward along the height direction and abut against the lower end of the rotor 02, allowing the rotor 02 to be lifted upward. The upper ejector assembly 5 can move downward along the height direction and abut against the upper end of the rotor 02. After both the upper ejector assembly 5 and the lower ejector assembly 6 abut against the rotor 02, the lower ejector assembly 6 continues to move upward along the height direction, while the upper ejector assembly 5 begins to retract upward along the height direction. Under the combined movement of the upper ejector assembly 5 and the lower ejector assembly 6, the rotor 02 clamped on the second assembly part 3 is disengaged from the second assembly part 3.

[0056] After the rotor 02 leaves the second assembly part 3, the support slide 31 of the second assembly part 3 moves longitudinally in the frame 1 via the second sliding assembly 11, moving away from directly above the stator 01. Then, the lower ejector assembly 6 moves downward in the height direction, and the upper ejector assembly 5 also extends downward in the height direction, causing the rotor 02 to move downward in the height direction and towards the stator 01 clamped on the first assembly part 2. Under the combined movement of the upper ejector assembly 5 and the lower ejector assembly 6, the rotor 02 is assembled with the stator 01 clamped on the first assembly part 2. In the combined movement of the upper ejector assembly 5 and the lower ejector assembly 6, the distance between the rotor 02 and the stator 01 can be controlled by controlling the movement distance of the upper ejector assembly 5 and the lower ejector assembly 6. That is, the upper ejector assembly 5 and the lower ejector assembly 6 can counteract the axial magnetic attraction between the stator 01 and the rotor 02 during assembly. By adjusting the feed distance of the upper ejector assembly 5 and the lower ejector assembly 6, a reasonable gap can be precisely maintained between the stator 01 and the rotor 02, avoiding friction or collision between the stator 01 and the rotor 02. This not only improves assembly efficiency and assembly accuracy, but also ensures the performance of the product.

[0057] It should be noted that the present invention does not limit the specific structure of the upper ejector assembly and the lower ejector assembly. They can be reasonably set according to actual needs, as long as they can ensure that the upper ejector assembly and the lower ejector assembly drive the rotor to move along the height direction.

[0058] For details, see Figure 8 and combined Figure 1-4As shown, in this embodiment, the lower ejector assembly 6 includes a lower ejector mounting base 60, a lower ejector moving base 61 is provided on the lower ejector mounting base 60, one end of the lower ejector moving base 61 is connected to the lower ejector driving part 63, and the other end is provided with a lower ejector 62. The lower ejector 62 is arranged along the height direction and can pass through the first assembly part 2 and the stator 01 under the drive of the lower ejector driving part 63, and abut against the lower end of the rotor 02.

[0059] In other words, the lower ejector pin assembly 6 mainly consists of a lower ejector pin mounting base 60, a lower ejector pin moving base 61, a lower ejector pin 62, and a lower ejector pin drive unit 63. The lower ejector pin mounting base 60 and the lower ejector pin drive unit 63 are both fixedly mounted along the height direction at the lower part of the frame 1, located below the first assembly part 2. The lower ejector pin moving base 61 is mounted along the transverse direction of the frame 1 (e.g., ...). Figure 1 (As shown in the Y direction) is set on the lower ejector mounting seat 60, one end of which is connected to the lower ejector drive unit 63. It can move along the height direction under the drive of the lower ejector drive unit 63. The lower ejector 62 is set at the other end of the lower ejector moving seat 61 along the height direction, located directly below the first assembly part 2, and coaxially set with the stator 01 on the first assembly part 2. It can pass through the first assembly part 2 and the stator 01 under the drive of the lower ejector drive unit 63 and abut against the lower end of the rotor 02 on the second assembly part.

[0060] For details, see Figure 8 and combined Figure 1-4 As shown, in this embodiment, the lower ejector mounting base 60 is a slide rail structure arranged along the height direction, the lower ejector moving base 61 is a slider structure arranged on the lower ejector mounting base 60, the lower ejector driving part 63 is a telescopic cylinder, the cylinder rod of the telescopic cylinder is connected to the end of the lower ejector moving base 61, and is used to drive the lower ejector moving base 61 to move along the height direction, and the lower ejector 62 is a rod-shaped structure arranged on the lower ejector moving base 61 along the height direction. In order to facilitate contact with the lower end of the rotor 02, the upper end of the lower ejector 62 is a tapered structure.

[0061] In other embodiments, the lower ejector assembly can also be of other structures, such as using an electric push rod to directly drive the rotor to move along the height direction. The present invention does not limit this, as long as it can ensure that the lower ejector assembly can stably and reliably abut against the lower end of the rotor and drive the rotor to move along the height direction.

[0062] See Figure 6 and combined Figure 7 , Figure 1-4 As shown, in this embodiment, the upper ejector assembly 5 includes an upper ejector drive part 50, an upper ejector mounting part 51, and an upper ejector 52. The upper ejector drive part 50 is located on the upper part of the frame 1 and is connected to the upper ejector mounting part 51. It is used to drive the upper ejector mounting part 51 to drive the upper ejector 52 to move downward, so that the upper ejector 52 abuts against the upper end of the rotor 02.

[0063] In other words, the upper ejector assembly 5 mainly consists of an upper ejector drive unit 50, an upper ejector mounting unit 51, and an upper ejector 52. The upper ejector drive unit 50 is fixedly mounted on the upper part of the frame 1 along the height direction via a support frame (not shown in the figure). The upper ejector mounting unit 51 is connected to the lower end of the upper ejector drive unit 50 and can move along the height direction under the drive of the upper ejector drive unit 50, so that the upper ejector 52 abuts against the upper end of the rotor 02. In this embodiment, the upper ejector drive unit 50 is a telescopic cylinder, and the cylinder rod of the telescopic cylinder is connected to the upper ejector mounting unit 51. The upper ejector 52 is a rod-shaped structure, arranged along the height direction, and the lower end of the upper ejector 52 is a conical structure to facilitate abutment against the upper end of the rotor 02. In other embodiments, the upper ejector assembly can also have other structures, and the present invention does not limit them, as long as it can ensure that the upper ejector assembly stably and reliably abuts against the upper end of the rotor, driving the rotor to move along the height direction.

[0064] Further, see Figure 6 and combined Figure 7 , Figure 1-4 As shown, in this embodiment, the upper ejector pin 52 is at least partially disposed within the upper ejector pin mounting portion 51 and extends along the height direction. The upper ejector pin 52 can move relative to the upper ejector pin mounting portion 51 along the height direction. The upper ejector pin mounting portion 51 is provided with a locking portion 53, which can limit the relative movement between the upper ejector pin 52 and the upper ejector pin mounting portion 51 in the height direction.

[0065] That is, the upper ejector pin 52 can be entirely located within the upper ejector pin mounting portion 51, or it can be partially located within the upper ejector pin mounting portion 51. The upper ejector pin 52 is arranged and extends along the height direction, that is, the height direction is the axial extension direction and mounting direction of the upper ejector pin 52. In this embodiment, the height direction refers to the height direction of the frame 1. In the height direction, the upper ejector pin 52 can move relative to the upper ejector pin mounting portion 51, so that the upper ejector pin 52 can be in different positions in the height direction. The length of the upper ejector pin 52 extending from the upper ejector pin mounting portion 51 can be adjusted as needed, so that the upper ejector pin 52 can be used in different applications, and the structural design is reasonable.

[0066] To prevent the ejector pin from moving arbitrarily within the mounting section, see [reference needed]. Figure 6-7 As shown, the upper ejector pin mounting part 51 is provided with a locking part 53, which can limit the relative movement between the upper ejector pin 52 and the upper ejector pin mounting part 51 in the height direction. By providing the locking part 53, the upper ejector pin 52 can be effectively and reliably locked in the height direction, preventing the upper ejector pin 52 from moving when it is not needed, and ensuring that the ejector pin assembly 51 can work stably and reliably.

[0067] For details, see Figure 6-7As shown, in this embodiment, the locking part 53 has a first state and a second state. In the first state, the locking part 53 locks the upper ejector pin 52, and the upper ejector pin 52 and the upper ejector pin mounting part 51 can move synchronously. In the second state, the locking part 53 releases the upper ejector pin 52, and the upper ejector pin 52 and the upper ejector pin mounting part 51 can move relative to each other.

[0068] That is, in the first state, the locking part 53 can lock the upper ejector pin 52, so that the upper ejector pin 52 and the upper ejector pin mounting part 51 are relatively fixed and can move synchronously. In other words, in the first state, the upper ejector pin assembly 5 can realize the function of the ejector pin in the prior art. In the second state, the locking part 53 can release the upper ejector pin 52, and the upper ejector pin 52 can move relative to the upper ejector pin mounting part 51, extending or retracting from the upper ejector pin mounting part 51, so that the upper ejector pin 52 moves to a suitable working state. In the second state, after the upper ejector pin 52 moves to the appropriate position, the locking part 53 changes back to the first state, locking the upper ejector pin 52, so that the upper ejector pin 52 can work stably and reliably.

[0069] It should be noted that the present invention does not limit the specific structure of the upper ejector pin mounting part, and can be reasonably set according to actual needs, as long as it can be used for the installation of the locking part and the ejector pin.

[0070] For details, see Figure 7 As shown, in this embodiment, the upper ejector pin mounting part 51 includes a mounting sleeve 511, the upper ejector pin 52 is at least partially located in the mounting cavity 5110 of the mounting sleeve 511, and the locking part 53 is provided on the mounting sleeve 511 and can extend into the mounting cavity 5110 to abut against the upper ejector pin 52 and lock the upper ejector pin 52.

[0071] In other words, the mounting sleeve 511 is arranged along the height direction, the upper ejector pin 52 is inserted into the mounting sleeve 511, and is at least partially located inside the mounting sleeve 511. The locking part 53 is provided on the mounting sleeve 511. Specifically, the locking part 53 is provided on the outside of the mounting sleeve 511. In the first state, the locking part 53 can extend from the outside of the mounting sleeve 511 into the mounting cavity 5110 and abut against the upper ejector pin 52 from the radially outer side of the upper ejector pin 52 to lock the upper ejector pin 52.

[0072] It should be further noted that the present invention does not limit the specific structure of the locking part, and can be reasonably set according to actual needs, as long as the pin can be locked when needed.

[0073] For details, see Figure 7As shown, in this embodiment, the locking part 53 includes a locking cylinder 530 and a locking block 531. The locking cylinder 530 is disposed on the upper ejector pin mounting part 51. The cylinder rod 532 of the locking cylinder 530 can extend into the mounting cavity 5110. The locking block 531 is disposed at the front end of the cylinder rod 532 and can abut against the upper ejector pin 52. By using the locking cylinder 530 and the locking block 531, the upper ejector pin 52 can be stably and reliably locked to the mounting sleeve 511.

[0074] To prevent relative sliding between the ejector pin and the locking block after locking, see [link / reference]. Figure 7 As shown, in this embodiment, the upper ejector pin 52 has a recess 521, and the locking block 531 can abut into the recess 521. The recess 521 can be a pit distributed circumferentially along the upper ejector pin 52, or it can be a groove. In other embodiments, the recess can also have other structures; the present invention does not limit this, as long as it facilitates reliable contact between the locking block and the ejector pin.

[0075] Further, see Figure 7 As shown, in this embodiment, a spring 512 is provided inside the mounting cavity 5110. One end of the upper ejector pin 52 abuts against the spring 512, and the other end extends out of the mounting cavity 5110. That is, the upper ejector pin 52 is driven by the spring 512. When the locking part 53 is in the second state, the spring 512 can push the upper ejector pin 52 out of the mounting cavity 5110, so that the upper ejector pin 52 is in its longest extended state. At this time, the locking part 53 can lock the upper ejector pin 52, that is, the locking part 53 is in the first state, so that the upper ejector pin 52 can move synchronously with the mounting part and can work reliably. In addition, the locking part 53 can also be in the second state, that is, the locking part 53 releases the upper ejector pin 52, so that the upper ejector pin 52 is in its longest extended state. After the upper ejector pin 52 abuts against the rotor 02, the spring 512 is compressed, and the upper ejector pin 52 retracts into the mounting cavity 5110 along the height direction. After the upper ejector pin 52 retracts a certain distance, the locking part 53 can lock the upper ejector pin 52, so that the upper ejector pin 52 is kept in the appropriate working position.

[0076] In other embodiments, the relative movement between the upper ejector pin and the upper ejector pin mounting part can also be achieved by other driving methods, such as electric push rods, gas springs, hydraulic components, etc. The present invention does not limit this and can make reasonable selections according to actual needs, as long as the relative movement between the upper ejector pin and the upper ejector pin mounting part can be achieved.

[0077] Further, see Figure 7As shown, in this embodiment, a first limiting protrusion 513 is provided in the mounting cavity 5110, and a second limiting protrusion 520 is provided on the upper ejector pin 52. Along the height direction, the first limiting protrusion 513 is located downstream of the second limiting protrusion 520, and is used to limit the length of the upper ejector pin 52 extending out of the mounting cavity 5110. By providing the first limiting protrusion 513 and the second limiting protrusion 520, the upper ejector pin 52 can be limited in its longest extended state, preventing it from slipping out of the mounting cavity 5110 and ensuring that the upper ejector pin 52 can work safely and reliably.

[0078] Additionally, to prevent the upper pin from wobbling after extending, see [reference needed]. Figure 7 As shown, in this embodiment, the outer end of the mounting sleeve 511 is provided with an extension sleeve 515, and the front end of the upper ejector pin 52 can extend out from the extension sleeve 515. The extension sleeve 515 is provided at the outer end of the mounting sleeve 511 along the height direction, and the upper ejector pin 52 can extend out from the extension sleeve 515. During operation, the extension sleeve 515 can guide and support the upper ejector pin 52, ensuring that the upper ejector pin 52 can work stably and reliably, and avoiding shaking.

[0079] See Figure 6-7 As shown, in this embodiment, the upper ejector pin mounting portion 51 is provided with a wing plate 514, which is arranged along the height direction. In this embodiment, the wing plates 514 are arranged on the upper ejector pin mounting portion 51 along the height direction. They can be symmetrically arranged on both sides of the mounting sleeve 511, or they can be evenly distributed along the circumference of the mounting sleeve 511. The present invention does not limit this and can be set according to actual needs. The wing plate 514 can drive the upper stator 03, or drive the stator 01 after it is assembled with the rotor 02 to move along the height direction towards the other rotor 02. It can work in coordination with the upper ejector pin 52, which can not only protect the upper ejector pin 52, but also improve working efficiency.

[0080] To achieve the assembly of multiple rotors or multiple stators and further improve assembly efficiency, see [link to relevant documentation]. Figure 1 As shown, in this embodiment, the frame 1 is also provided with a third assembly part 4 for clamping the upper stator 03. In the height direction of the frame 1, the third assembly part 4, the second assembly part 3 and the first assembly part 2 are arranged sequentially from top to bottom. The upper stator 03 can be assembled with the rotor 02 under the drive of the third assembly part 4.

[0081] In other words, the frame 1 is provided with a third assembly part 4, a second assembly part 3 and a first assembly part 2 from top to bottom. The third assembly part 4 is fitted with an upper stator 03, the second assembly part 3 is fitted with a rotor 02 and the first assembly part 2 is fitted with a stator 01. Driven by the third assembly part 4, the upper stator 03 and the rotor 02 are assembled together. That is, the assembly equipment 00 can be used to assemble a double stator disc motor.

[0082] In the initial state, the drive mounting plate 100 is moved, causing the first assembly part 2 and the second assembly part 3 to extend horizontally from the frame 1 and enter the loading position. The stator 01 is manually hoisted onto the tray 20 of the first assembly part 2, aligning the stator 01 with the limiting member, and then fixed onto the tray 20 by the clamping member 21. Then, the drive in the second assembly part 3 is activated, causing the carrier slide 31 to extend horizontally to the loading position. The rotor 02 is manually hoisted onto the carrier slide 31, clamping it onto the positioning block 32 of the carrier slide 31. Afterward, the drive in the drive mounting plate 100 is activated, causing the mounting plate 100, along with the stator 01 and rotor 02, to return horizontally to the frame 1 and enter the assembly position. Then, the third assembly section 4 extends horizontally to the loading position, and the upper stator 03 is manually hoisted onto the third assembly section 4. The third assembly section 4 then returns horizontally to the frame 1 and enters the assembly position. The "loading position" mentioned in this article refers to the state and position of each assembly section when clamping the various components onto the assembly equipment.

[0083] The above process is the loading process, used to clamp the stator 01, rotor 02, and upper stator 03 onto the corresponding assembly parts and place them in their corresponding assembly positions, thereby facilitating the automated assembly of the stator and rotor by the assembly equipment. This invention does not limit the order of the above processes; reasonable selection and settings can be made according to the actual assembly process and clamping requirements, as long as it ensures that each component is in its corresponding assembly position. The "assembly position" mentioned herein refers to the final position of the stator, rotor, and upper stator before assembly, at which point the stator, rotor, and upper stator are coaxial in the height direction.

[0084] After loading, the components are assembled. The locking part 53 in the upper ejector assembly 5 locks the upper ejector pin 52 to prevent it from retracting. The upper ejector pin drive part 50 drives the upper ejector pin mounting part 51 to move downward in the height direction, causing the wing plate 514 on the upper ejector pin mounting part 51 to press against the upper stator 03, and driving the upper stator 03 to move downward in the height direction. When the upper ejector pin 52 abuts against the upper end of the rotor 02, the lower ejector pin 62 moves upward in the height direction under the drive of the lower ejector pin drive part 63 until the lower ejector pin 62 abuts against the lower end of the rotor 02. After the upper ejector pin assembly 5 and the lower ejector pin assembly 6 complete abutting against the rotor 02, the lower ejector pin drive part 63 continues to drive the lower ejector pin 62 to move upward in the height direction, causing the rotor 02 to leave the positioning block 32 on the second assembly part 3. The bearing slide 31 moves longitudinally in the frame 1 through the second sliding assembly 11 and moves away from above the stator 01.

[0085] Then, the lower ejector assembly 6 moves downward along the height direction, and the upper ejector drive part 50 also drives the upper ejector mounting part 51 to move downward along the height direction, so that the rotor 02 moves downward along the height direction and approaches the stator 01 clamped on the first assembly part 2. Under the combined movement of the upper ejector assembly 5 and the lower ejector assembly 6, the rotor 02 is assembled with the stator 01 clamped on the first assembly part 2. During assembly, the locking block 531 on the locking part 53 locks the upper ejector pin 52, preventing the upper ejector pin 52 from retracting. This ensures that the rotor 02 is stably and reliably assembled with the stator 01. The distance between the rotor 02 and the stator 01 can be controlled by controlling the movement distance of the upper ejector pin assembly 5 and the lower ejector pin assembly 6. In other words, the axial magnetic attraction between the stator 01 and the rotor 02 during assembly can be counteracted by the upper ejector pin assembly 5 and the lower ejector pin assembly 6, so that the stator 01 and the rotor 02 maintain a reasonable gap precisely, avoiding friction or collision between the stator 01 and the rotor 02. This not only improves assembly efficiency and accuracy but also ensures product performance.

[0086] With the third assembly part 4 present, the wing plate 514 in the upper ejector assembly 5 can abut against the upper stator 03 clamped on the third assembly part 4. When the rotor 02 is assembled with the stator 01 clamped on the first assembly part 2, the wing plate 514 and the upper stator 03 can provide an upward supporting force in the height direction. The supporting force can counteract the axial magnetic attraction between the upper stator 03 and the rotor 02 during assembly, so that the upper stator 03 and the rotor 02 maintain a reasonable gap precisely, avoiding friction or collision between the upper stator 03 and the rotor 02. This not only improves assembly efficiency and assembly accuracy, but also ensures product performance.

[0087] After the rotor 02 and the stator 01 clamped on the first assembly part 2 are assembled, the locking part 53 in the upper ejector assembly 5 retracts, causing the upper ejector 52 to relax. The upper ejector drive part 50 can drive the upper ejector mounting part 51 to retract upward in the height direction. Under the action of the spring 512, the upper ejector 52 continues to abut against the upper end of the rotor 02. At this time, the third assembly part 4 drives the upper stator 03 to move downward in the height direction, so that the upper stator 03 and the rotor 02 are assembled.

[0088] After the rotor 02 and upper stator 03 are assembled, workers use connectors (such as bolts) to fix the assembled stator 01, rotor 02, and upper stator 03. The third assembly part 4, upper ejector pin assembly 5, and lower ejector pin assembly 6 all separate, driving the mounting plate 100 to move. This causes the mounting plate 100 to pull the assembled double-stator disc motor out of the frame 1. The assembled double-stator disc motor is then manually hoisted onto the transport equipment for the next process. Simultaneously, flexible production of different types of disc motors can be achieved by quickly changing the pallet, positioning block, upper ejector pin mounting part, and lower ejector pin of the assembly equipment as needed. This improves the applicability and versatility of the assembly equipment, thereby increasing its production efficiency and multi-product production capacity.

[0089] In another embodiment of the present invention, the frame 1 is further provided with a third assembly part 4 for clamping the stator 01 and rotor 02 after assembly. In the height direction of the frame 1, the third assembly part 4, the second assembly part 3 and the first assembly part 2 are arranged sequentially from top to bottom. The stator 01 after assembly with the rotor 02 can be assembled with another rotor 02 clamped on the second assembly part 3 under the drive of the third assembly part 4.

[0090] For details, see Figure 4 and Figure 5 and combined Figure 1-3 As shown, in this embodiment, the third assembly part 4 includes: a main mounting plate 40, which is disposed on the frame 1; a sliding plate 41, which is disposed on the main mounting plate 40 through a third sliding assembly 12 and can move along the height direction; and a clamping assembly 42, which is disposed on the sliding plate 41 and can move along the horizontal direction, for clamping the stator 03, or clamping the stator 01 and rotor 02 after the assembly is completed.

[0091] In other words, the third assembly part 4 is mainly composed of a main mounting plate 40, a sliding plate 41, and a clamping assembly 42. The main mounting plate 40 is fixedly mounted on the frame 1. The sliding plate 41 is mounted on the main mounting plate 40 via a third sliding assembly 12. The third sliding assembly 12 is arranged along the height direction and is composed of a third sliding guide rail 121 and a third sliding drive unit 120. The third sliding guide rail 121 is arranged along the height direction on the main mounting plate 40, and the third sliding drive unit 120 is arranged along the height direction on the frame 1. The lower end of the third sliding drive unit 120 is connected to the sliding plate 41 and is used to drive the sliding plate 41 to move along the height direction.

[0092] Furthermore, the clamping assembly 42 is mounted on the sliding plate 41 and can move together with the sliding plate 41 in the height direction, so that the upper stator 03 clamped on the clamping assembly 42 or the stator 01 after being assembled with the rotor 02 approaches the rotor 02 clamped on the second assembly part 3 in the height direction for assembly. At the same time, the clamping assembly 42 can also move in the horizontal direction, which facilitates the clamping of the upper stator 03 or the stator 01 after being assembled with the rotor 02 on the clamping assembly 42. After clamping, the distance between the upper stator 03 or the stator 01 and the rotor 02 in the horizontal direction can be adjusted so that the upper stator 03 or the stator 01 and the rotor 02 are in a coaxial state during assembly, ensuring assembly accuracy.

[0093] For details, see Figure 4 and combined Figure 5 and Figure 1-3 As shown, in this embodiment, the clamp assembly 42 includes a clamp mounting plate 420 and a clamp 43. The clamp mounting plate 420 is mounted on the sliding plate 41 via the fourth sliding assembly 13, and the clamp 43 is mounted on the clamp mounting plate 420 for clamping the stator 03, or clamping the stator 01 and rotor 02 after assembly.

[0094] That is, the clamp 43 is mounted on the clamp mounting plate 420, and the clamp mounting plate 420 is mounted on the sliding plate 41 via the fourth sliding assembly 13. The fourth sliding assembly 13 consists of a fourth sliding guide rail 130 and a fourth sliding drive unit 131. The fourth sliding guide rail 130 is horizontally mounted on the sliding plate 41, and the fourth sliding drive unit 131 is horizontally mounted on the sliding plate 41. One end of the fourth sliding drive unit 131 is mounted on the sliding plate 41, and the other end is connected to the sliding plate 41, for driving the clamp mounting plate 420 to move horizontally. By setting the third sliding assembly 12 and the fourth sliding assembly 13, the clamp 43 can move in both the height and horizontal directions, which facilitates the adjustment of the position of the upper stator 03 clamped on the third assembly part 4 or the stator 01 after being assembled with the rotor 02, thereby improving the assembly accuracy and assembly efficiency.

[0095] It should be noted that the present invention does not limit the specific structure of the clamp. It can be reasonably selected and set according to actual needs, as long as it can stably and reliably clamp the stator or the stator after it has been assembled with the rotor.

[0096] For details, see Figure 4 and combined Figure 5 and Figure 1-3As shown, in this embodiment, the clamp 43 includes a transition plate 44, a pair of grippers 430 and gripper drive unit 431 disposed opposite to each other on the clamp mounting plate 420. The transition plate 44 is connected to the upper stator 03, or to the stator 01 after the rotor 02 is assembled. The gripper drive unit 431 is used to drive the grippers 430 to clamp the transition plate 44.

[0097] The transition plate 44 is connected to the upper stator 03 or the stator 01 after being assembled with the rotor 02. One side of the transition plate 44 is provided with a connector 440 for being clamped by the gripper 430, and the other side is provided with a guide part 443, which can extend into the upper stator 03 or the stator 01 to guide the upper stator 03 or the stator 01 to connect with the connecting plate 441 on the transition plate 44. The connecting plate 441 is provided with a clamping hole 442, which corresponds to the mounting hole on the upper stator 03 or the stator 01. The connecting parts (such as bolts) are used to install the transition plate 44 on the upper stator 03 or the stator 01 through the clamping hole 442 and the mounting hole. The gripper drive part 431 can drive the gripper 430 to clamp the connector 440 on the transition plate 44, thereby achieving the clamping of the upper stator 03 or the stator 01. By opening and closing the gripper 430, the transition plate 44 can be quickly clamped, thereby enabling the upper stator 03 or stator 01 to be quickly clamped, improving feeding efficiency and assembly efficiency.

[0098] As described above, the assembly equipment provided by this invention, through the relative movement between the second assembly part and the first assembly part, can adjust the positional relationship between the rotor and the stator, so that the axis of the rotor and the axis of the stator are perfectly aligned in the height direction by their own gravity, ensuring that the rotor and stator are in a coaxial state, facilitating assembly, avoiding the problem of axis misalignment, and improving assembly accuracy. Simultaneously, by employing vertical assembly, relying on the relative movement between the second assembly part and the first assembly part and the self-gravity of the rotor and stator, the assembly of the rotor and stator is achieved, improving assembly efficiency.

[0099] In summary, the embodiments provided above are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
