Description

Technical Field

[0001] This application relates to the field of motor manufacturing equipment, and more particularly to an assembly apparatus and equipment for stators and insulation components. Background Technology

[0002] During the manufacturing process of an electric motor, insulating components (flexible insulating materials) need to be assembled onto the motor stator, such as... Figure 1 As shown, the stator includes a first annular body and multiple partitions. The partitions are arranged circumferentially along the first annular body and are formed on the inner circumferential surface of the first annular body. A winding groove is formed between two circumferentially adjacent partitions and the inner circumferential wall of the first annular body. Figure 2 As shown, the insulating sleeve includes a second annular body, a third annular body, and multiple jackets. The third annular body includes multiple arc-shaped partitions spaced circumferentially on the lower surface of the second annular body. The width between two adjacent arc-shaped partitions is equal to the width of the partition. A jacket is provided between two circumferentially adjacent arc-shaped partitions. The jackets correspond one-to-one with the partitions of the stator. The jackets include two inner partitions, which are respectively located at the relatively close ends of two adjacent arc-shaped partitions. After the stator and the insulating components are assembled, the outer wall of the arc-shaped partition is in contact with the inner circumferential wall of the stator. The two inner partitions of the jacket are in contact with the two side walls of the partition in the width direction.

[0024] The assembly apparatus and equipment of this application have at least the following beneficial effects:

[0025] In operation, the assembly device of this application installs the stator into the through hole of the disc. Then, the pick-and-place mechanism picks up the insulating component and moves it to directly above the stator, slowly inserting it downwards into the stator. Just before the insulating component is fully inserted, the drive assembly moves the extrusion block radially closer to the insulating component. The arc-shaped extrusion surface of the extrusion block radially extrudes multiple arc-shaped partitions of the insulating component, deforming them towards the axis of the insulating component. This reduces the outer diameter of the third annular body formed by the multiple arc-shaped partitions, allowing it to be smoothly inserted into the first annular body of the stator under the drive of the pick-and-place mechanism. Simultaneously, the extrusion block is also equipped with… There are inner support bars corresponding to the jacket. When the extrusion block moves radially toward the insulating component, the inner support bars are inserted into the jacket and expand the jacket, so that the inner width of the jacket increases, allowing it to be smoothly fitted into both sides of the partition under the drive of the material handling mechanism, thereby achieving the insulation of the insulating component covering the inner peripheral wall of the stator and the partition. This application, by setting the radially moving extrusion block, can extrude the insulating component to deform it, ensuring that the lower edge of the insulating component can be smoothly pre-assembled onto the stator. Then, the material handling mechanism drives the insulating component downward to be assembled into the stator, which can greatly improve the assembly success rate and assembly efficiency, and can be adapted to mass assembly production.

[0057] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0058] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0059] This embodiment discloses an assembly device and equipment for a stator and an insulating component. To facilitate understanding of the technical solution of this embodiment, the structure of the stator 700 and the insulating component 800 in this embodiment will be introduced first.

[0060] like Figure 1 As shown, the stator 700 includes a first annular body 710 and a plurality of partitions 720. One end of the partition 720 is connected to the inner peripheral wall of the first annular body 710. The partition 720 has the same axial thickness as the first annular body 710. The plurality of partitions 720 are equally spaced along the circumference of the first annular body 710 on the inner side of the first annular body 710. A winding groove 700a is formed between two circumferentially adjacent partitions 720 and the inner peripheral wall of the first annular body 710.

[0061] like Figure 2As shown, the insulating component 800 includes a second annular body 810, a third annular body 820, and multiple sleeves 830. The lower surface 811 of the second annular body is horizontal. The third annular body 820 is coaxially disposed on the lower surface 811 of the second annular body. The outer diameter of the third annular body 820 is equal to or slightly larger than the inner diameter of the first annular body 710 of the stator 700. For example, the outer diameter of the third annular body 820 is 1 to 1.1 times the inner diameter of the first annular body 710. The third annular body 820 includes multiple arc-shaped partitions 821. The length direction of the arc-shaped partitions 821 is arc-shaped. The multiple arc-shaped partitions 821 are equally spaced along the circumference of the second annular body 810 on the lower surface 811 of the second annular body. The multiple arc-shaped partitions 821 arranged at intervals form the third annular body 820. The spacing width between two circumferentially adjacent arc-shaped partitions 821 is equal to the width of the spacer portion 720 of the stator 700. So that the third annular body 820 can avoid the partition 720 and be inserted downward into the first annular body 710 of the stator 700; a plurality of sleeves 830 are equally spaced along the circumference on the third annular body 820, and the sleeves 830 are correspondingly arranged with the partition 720. The sleeves 830 include two inner partitions 831 arranged opposite each other along the circumference of the third annular body 820. The two inner partitions 831 are respectively arranged at the ends of two adjacent arc-shaped partitions 821. Specifically, the two inner partitions 831 are respectively arranged at the relatively close ends of two adjacent arc-shaped partitions 821. The spacing width of the two inner partitions 831 of the sleeve 830 is equal to the width of the partition 720. After the stator 700 and the insulating component 800 are assembled, the outer wall of the arc-shaped partition 821 is in contact with the inner circumferential wall of the stator 700, and the two inner partitions 831 of the sleeve 830 are in contact with the two side walls of the partition 720 in the width direction. In some preferred embodiments, the jacket 830 further includes an upper partition 832, with two inner partitions 831 connected to each end of the upper partition 832. After the stator 700 and the insulating component 800 are assembled, the upper partition 832 is in contact with the upper surface of the partition 720.

[0062] like Figure 3 As shown, the assembly device 300 of this embodiment includes a material handling mechanism and a pressing mechanism. In this embodiment, the following directions are defined: the X-axis direction is configured as the first horizontal direction, the Y-axis direction is configured as the second horizontal direction, and the Z-axis direction is configured as the height direction. The X-axis direction, the Y-axis direction, and the Z-axis direction intersect each other perpendicularly to form a spatial coordinate system.

[0063] like Figure 3 As shown, the material handling mechanism includes a first frame 310, a module integration 320, and a material handling assembly 330, as detailed below:

[0064] The first frame 310 is fixedly mounted on the workbench or other base surface to provide an installation position for the module integration 320.

[0065] The module integration 320 includes an X-axis module 3201 and a Z-axis module 3202. The X-axis module 3201 is mounted on the first frame 310. The X-axis module 3201 is used to drive the Z-axis module 3202 to move in the X-axis direction. The Z-axis module 3202 is used to drive the material handling assembly 330 to move in the Z-axis direction.

[0066] like Figure 4 As shown, the material handling assembly 330 includes an upper fixed seat 331, a lower fixed seat 332, a slide 333, a first telescopic member 334, and multiple hook and support units 335 arranged around the Z-axis. The upper fixed seat 331 is connected to the Z-axis module 3202, and can be driven to move in the X-axis and Z-axis directions through the X-axis module 3201 and the Z-axis module 3202. The upper fixed seat 331 and the lower fixed seat 332 are spaced a certain distance apart in the Z-axis direction, and are fixedly connected by a mounting rod. The slide... 333 is slidably disposed between the upper fixed seat 331 and the lower fixed seat 332 along the Z-axis direction. For example, the slide 333 is slidably disposed on the upper side of the lower fixed seat 332 through the first guide post. The first telescopic member 334 is disposed on the upper fixed seat 331. The telescopic end of the first telescopic member 334 is connected to the slide 333. The telescopic direction of the first telescopic member 334 is configured to be the Z-axis direction. The slide 333 is driven to move in the Z-axis direction by the first telescopic member 334. In this embodiment, the first telescopic member 334 includes a telescopic cylinder or other actuator with linear telescopic capability.

[0067] like Figure 4 As shown, there are multiple hook support units 335. In this embodiment, it is preferred that there are three hook support units 335, and the three hook support units 335 are equally spaced on the lower fixed base 332 around the Z-axis.

[0068] like Figure 4 and Figure 5As shown, the hook support unit 335 includes a wedge block 336, a lever 337, a roller 338, a hook support member 339, and a first elastic member 3310; the wedge block 336 is connected to the slide block 333 and can move with the slide block 333 in the Z-axis direction. The wedge block 336 is provided with a driving inclined surface 3361, which has a predetermined angle with the Z-axis direction, ranging from 30 degrees to 80 degrees; the middle part of the lever 337 is hinged to the lower fixed seat 3. 32. A roller 338 is rolled on the first end (i.e., the upper end) of lever 337. The outer circumferential surface of roller 338 can roll into contact with the driving inclined surface 3361 of wedge block 336. When slide block 333 drives wedge block 336 to move downward along the Z-axis, the first end of lever 337 rotates toward slide block 333 and moves closer to it. Therefore, hook support 339 on the second end of lever will move away from and release the constraint on insulating member 800. Hook support 339 is set on lever 337. At the second end (i.e., the lower end) of 37, when the slide block 333 drives the wedge block 336 to move upward along the Z-axis, under the action of the first elastic element 3310, the hook support 339 moves toward the insulating element 800 and moves to the lower surface 811 of the second annular body of the insulating element 800. The hook support 339 contacts the lower surface 811 of the second annular body and supports the insulating element 800 in the Z-axis direction, thereby realizing the picking up of the insulating element 800. The first elastic element 3310 is preferably a spring. The two ends of the first elastic element 3310 are respectively connected to the lower fixed seat 332 and the lever 337. The extension and retraction direction of the first elastic element 3310 is configured to be horizontal. When the slide block 333 drives the wedge block 336 to move downward along the Z-axis, the first elastic element 3310 will deform. After being deformed and compressed, the first elastic element 3310 has the tendency to push the second end of the lever 337 and the hook support 339 toward the insulating element 800. In some preferred embodiments, the hook support 339 is provided with a horizontal surface that can fit and contact the lower surface 811 of the second annular body. That is, the hook support 339 supports the lower surface 811 of the second annular body of the insulating member 800 through the horizontal surface, thereby ensuring that the insulating member 800 is in a horizontal state after being taken out.

[0069] like Figure 5 As shown, in this embodiment, multiple hook support units 335 are provided to support the insulating component 800 from multiple points, ensuring the stability of the insulating component 800. The first telescopic component 334 can drive the slide block 333 and the wedge block 336 to move, thereby simultaneously driving the levers 337 of the multiple hook support units 335 to rotate. The synchronization is high, which can ensure the smooth progress of the assembly work. Furthermore, the second annular body 810 of the insulating component 800 is supported by the hook support component 339, so the insulating component 800 will not be subjected to horizontal compression force. Therefore, the insulating component 800 will not undergo large deformation, which can ensure the assembly success rate of the insulating component 800.

[0070] like Figure 5As shown, in some preferred embodiments, a centering column 3311 and a first alignment block 3312 are provided on the lower surface of the lower fixing seat 332. The centering column 3311 is coaxially arranged with the lower fixing seat 332 and the first telescopic member 334. The centering column 3311 extends away from the lower fixing seat 332 along the Z-axis direction. The centering column 3311 is cylindrical in shape, and its outer diameter is equal to the outer diameter of the second annular body 810 of the insulating member 800. When picking up materials, the centering column 3311... The first alignment block 3312 is inserted downward into the second annular body 810 of the insulating member 800 to achieve forced alignment with the insulating member 800. Multiple first alignment blocks 3312 are arranged at intervals along the circumference of the centering post 3311. The first alignment blocks 3312 can be disposed on the lower surface of the lower fixing seat 332 or on the outer circumferential surface of the centering post 3311. Alignment grooves 830a are formed between two adjacent sleeves 830 of the insulating member 800 along the circumferential direction (e.g., ...). Figure 2 As shown), when the material is taken down along the Z-axis, the first alignment block 3312 corresponds to the alignment groove 830a in the Z-axis direction. The first alignment block 3312 can be inserted downward into the alignment groove 830a. Furthermore, the cross-sectional shape of the first alignment block 3312 in the horizontal direction is the same as the inner circumferential contour of the alignment groove 830a. Therefore, the first alignment block 3312 can restrict the insulation component 800 from rotating around its axis.

[0071] In this embodiment, when the insulating component 800 is being picked up, the centering column 3311 is first used to ensure that it is coaxial with the insulating component 800. The first alignment block 3312 restricts the degree of freedom of rotation of the insulating component 800. Finally, the hook support 339 restricts the insulating component 800 from moving downward away from the centering column 3311. This ensures the positional accuracy of the insulating component 800 after it is picked up, thereby improving the success rate during assembly.

[0072] like Figure 4 and Figure 5 As shown, in some preferred embodiments, the material handling assembly 330 further includes multiple push rods 3314 connected to the slide block 333. The upper end of the push rod 3314 is connected to the slide block 333, and the lower end of the push rod 3314 is used to push the insulating member 800 downward. The push rod 3314 is provided in a one-to-one correspondence with the sleeve 830 of the insulating member 800. The push rod 3314 can push the upper partition 832 of the sleeve 830 downward, so that the insulating member 800 is pressed downward onto the stator 700. The lower fixed seat 332 is provided with sliding holes corresponding to the push rods 3314. The sliding holes pass through the lower fixed seat 332 along the Z-axis direction and are used to avoid the push rods 3314.

[0073] In this embodiment, when the insulating component 800 is assembled onto the stator 700, the insulating component 800 deforms under the action of the pressing block 350, allowing the lower end of the insulating component 800 to be smoothly assembled onto the stator 700. After the lower end of the insulating component 800 is fitted onto the stator 700, the slide block 333 moves downward, causing the wedge block 336 to push the second end (i.e., the lower end) of the lever 337 away from the centering column 3311, and the hook support members 33 of the three hook support units 335... When the insulator 800 is in the open state and released, although the push rod 3314 will also move downward with the slide 333, the push rod 3314 has not yet extended downward to the lower fixed seat 332. Then the slide 333 continues to move downward, and the push rod 3314 extends downward to the lower fixed seat 332 and pushes the upper partition 832 of the jacket 830. Multiple push rods 3314 together push the insulator 800 downward into the stator 700. In this embodiment, only one first telescopic member 334 is provided, which can not only realize the placement and removal of the insulator 800, but also realize the downward assembly of the insulator 800. It should be noted that during the process of the push rod 3314 contacting and pressing down on the upper partition 832 of the sleeve 830, the roller 338 at the upper end of the lever 337 will pass over the driving inclined surface 3361 of the wedge block 336 and contact and engage with the vertical surface (the surface parallel to the Z-axis) on the wedge block 336. At this time, even if the slide block 333 and the wedge block 336 continue to move down, they will not push the lever 337 to rotate, thus avoiding the wedge block 336 from excessively pushing the lever 337 to rotate.

[0074] like Figure 6 and Figure 7As shown, the extrusion mechanism includes a disc 340, extrusion blocks 350, and a drive assembly 360. The disc 340 is a circular structure with a certain thickness. A receiving hole 340a for accommodating the stator 700 is provided at the axial center of the disc 340. The receiving hole 340a is circular in shape, and its inner diameter is equal to the outer diameter of the first annular body 710 of the stator 700. Multiple extrusion blocks 350 are slidably disposed on the disc 340. The sliding direction of the extrusion blocks 350 is configured to be radial to the disc 340. The extrusion blocks 350 can slide radially along the disc 340 and extend into the upper side of the receiving hole 340a. Each extrusion block 350 is provided with an arc-shaped extrusion surface 3521 and inner support bars 353 corresponding to the jacket 830. The arc-shaped extrusion surface 3521 of block 350 can form a circular extrusion ring. Since multiple extrusion blocks 350 can slide radially, the circular extrusion ring formed by multiple arc-shaped extrusion surfaces 3521 can change its diameter. Before the insulating component 800 is assembled onto the stator 700, the arc-shaped extrusion surface 3521 extrudes the arc-shaped spacer 821 of the insulating component 800 radially along the disk 340, causing the arc-shaped spacer 821 to deform toward the axis of the insulating component 800. By extruding multiple arc-shaped spacers 821 of the insulating component 800 through multiple arc-shaped extrusion surfaces 3521, the outer diameter of the third annular body 820 formed by multiple arc-shaped spacers 821 becomes smaller, thereby ensuring that the third annular body 820 of the insulating component 800 can be smoothly inserted downward into the first annular body 710 of the stator 700.

[0075] like Figure 7 and Figure 8 As shown, in this embodiment, the inner support bar 353 extends toward the axis of the disk 340. When the pressing block 350 slides radially, the inner support bar 353 is inserted into the sleeve 830 of the insulating member 800 radially along the disk 340. Since the width of the inner support bar 353 is greater than the inner width of the sleeve 830, the inner support bar 353 can open the sleeve 830, making its width larger, so that the sleeve 830 can be smoothly inserted downwards into both sides of the spacer 720 of the stator 700.

[0076] like Figure 6 As shown, the drive assembly 360 is connected to the extrusion block 350. The drive assembly 360 is used to drive the extrusion block 350 to slide radially on the disk 340. In addition to the structure described in this embodiment, the drive assembly 360 can also be a linear drive mechanism such as a telescopic cylinder or an electric push rod. For example, by setting a telescopic cylinder that corresponds one-to-one with the extrusion block 350, the extrusion block 350 can also be driven to slide radially on the disk 340.

[0077] like Figure 9As shown, in this embodiment, the extrusion block 350 includes a sliding body 351, a radial extrusion part 352, and an inner support bar 353. The sliding body 351 is rectangular in shape, and the disc 340 is provided with radial grooves corresponding to the extrusion block 350 (e.g., ...). Figure 8 As shown, the length direction of the radial groove intersects perpendicularly with the axis of the disk 340; the sliding body 351 is slidably disposed in the radial groove, which restricts the sliding body 351 to slide only radially within the disk 340; the middle position of the radial extrusion part 352 is connected to the end of the sliding body 351, and one end face of the radial extrusion part 352 facing the axis of the disk 340 is configured as an arc-shaped extrusion surface 3521, which can fit and contact the outer peripheral surface of the arc-shaped partition 821, thereby extruding the arc-shaped partition 821 radially; one end of the inner support bar 353 is connected to the middle position of the arc-shaped extrusion surface 3521, and the length direction of the inner support bar 353 is consistent with the sliding direction of the sliding body 351.

[0078] like Figure 9 As shown, in some preferred embodiments, the inner support bar 353 has a first chamfer 3531 at one end away from the radial extrusion part 352. The first chamfer 3531 is formed by beveling the end face and horizontal side of the inner support bar 353. It can be a rounded corner or a bevel. By setting the first chamfer 3531 at the end of the inner support bar 353, the width at the end of the inner support bar 353 is smaller than the width at other positions. When the inner support bar 353 is inserted into the sleeve 830, the inner support bar 353 can be inserted into the sleeve 830 more smoothly because the width at the end of the inner support bar 353 is smaller, avoiding the situation where the inner support bar 353 hits the arc-shaped partition 821.

[0079] like Figure 9As shown, in some preferred embodiments, the inner support bar 353 has two sides in its width direction, defined as a left side and a right side, which are symmetrically arranged. Both the left and right sides include interconnected inner support surfaces 3532 and clearance surfaces 3533. The inner support surfaces 3532 are located below the clearance surfaces 3533. The width between the two inner support surfaces 3532 is greater than the inner width of the sleeve 830. Therefore, when the inner support bar 353 is inserted into the sleeve 830, the two inner support surfaces 3532 can expand the sleeve 830, increasing its inner width. The clearance surface 3533 can be an arc surface or a slope. The clearance surface 3533 is connected to the upper top surface of the inner support surface 3532 and the inner support bar 353 respectively. When the inner support bar 353 is inserted into the sleeve 830, although the clearance surface 3533 is part of the side of the inner support bar 353, the clearance surface 3533 does not contact the inner side of the sleeve 830, that is, the clearance surface 3533 does not contact the inner side of the inner partition 831. Therefore, when the inner support bar 353 is inserted into the sleeve 830, the friction between the inner support bar 353 and the sleeve 830 can be reduced, thereby effectively avoiding unnecessary deformation of the sleeve 830 due to excessive friction, and thus avoiding adverse effects on the subsequent assembly of the sleeve 830.

[0080] like Figure 6 As shown, in some preferred embodiments, the drive assembly 360 includes a drive disk 361, a drive wheel 362, a connector 363, and a second telescopic member 364. The drive disk 361 is circular in shape and is rotatably mounted on the disk 340. The drive disk 361 and the disk 340 are coaxially corresponding. The drive disk 361 is provided with a hole for the insulating member 800 to pass through. This hole is coaxially corresponding to the receiving hole 340a on the disk 340 for accommodating the stator 700. In some preferred embodiments, the disk 340 is provided with a rotating circular groove. The rotating circular groove is coaxially mounted on the disk 340. The inner diameter of the rotating circular groove is opposite to the outer diameter of the drive disk 361. The drive disk 361 is coaxially mounted in the rotating circular groove and can rotate relative to the disk 340 within the rotating circular groove.

[0081] like Figure 7As shown, the drive disk 361 is provided with inclined grooves 361a corresponding to the extrusion blocks 350. Multiple inclined grooves 361a are evenly spaced along the circumference of the drive disk 361. The length direction of the inclined grooves 361a is tangent to the circumference of the drive disk 361. The inner width of the inclined grooves 361a is slightly larger than the outer diameter of the drive wheel 362, which can be 1.01 to 1.1 times larger. The drive wheel 362 is corresponding to the extrusion block 350 and is rotatably mounted on the extrusion block 350, with its axial direction aligned with the Z-axis. The drive wheels 362 are positioned within the inclined grooves 361a. When the drive disk 361 rotates, the inner wall of the inclined groove 361a can push the drive wheel 362. During the radial movement of the disc 340, since the drive wheel 362 is connected to the extrusion block 350 and the extrusion block 350 can only slide radially, the extrusion block 350 slides radially when the drive disc 361 rotates. One end of the connector 363 is connected to the drive disc 361, and the other end of the connector 363 is hinged to the telescopic end of the second telescopic member 364. The second telescopic member 364 is fixedly mounted on the disc 340 or other external structure. The telescopic direction of the second telescopic member 364 is configured to be tangential to the drive disc 361. Therefore, when the second telescopic member 364 extends or retracts, it can drive the drive disc 361 to rotate through the connector 363. The second telescopic member 364 includes linear telescopic elements such as telescopic cylinders or electric push rods.

[0082] In this embodiment, the second telescopic member 364 drives the drive disk 361 to rotate, thereby synchronously driving all the extrusion blocks 350 to extrude the insulating member 800, ensuring that the insulating member 800 is subjected to uniform force when it is extruded. On the other hand, this method is easy to control, and the sliding amount of all the extrusion blocks 350 can be adjusted by controlling the extension amount of the second telescopic member 364 alone.

[0083] The working principle of the stator and insulation assembly device in this embodiment is as follows:

[0084] The first step is to install the stator 700 into the receiving hole 340a of the disc 340;

[0085] In the second step, the X-axis module 3201 drives the pick-and-place assembly 330 to move above the insulating component 800, and the Z-axis module 3202 drives the pick-and-place assembly 330 to move downward. When the pick-and-place assembly 330 is a certain distance away from the insulating component 800, the first telescopic component 334 extends, the lever 337 is pushed to rotate, and the hook support 339 at the lower end of the lever 337 moves away from the centering column 3311. At this time, the hook support 339 of the three hook support units 335 are in an open state.

[0086] In the third step, the Z-axis module 3202 drives the centering column 3311 to insert downward into the insulating component 800. At the same time, the first alignment block 3312 is also inserted into the alignment groove 830a of the insulating component 800. Then, the first telescopic component 334 retracts upward. Under the action of the reset force of the first elastic component 3310, the hook support components 339 of the three hook support units 335 move synchronously toward the insulating component 800 and support the lower surface 811 of the second annular body of the insulating component 800.

[0087] Fourth step, Z-axis module 3202 drives the pick-and-place assembly 330, which has been connected to the insulating component 800, to rise to a certain height. Then, X-axis module 3201 drives the pick-and-place assembly 330 and the insulating component 800 to move along the X-axis direction to directly above the stator 700. Z-axis module 3202 drives the insulating component 800 to move downwards towards the stator 700.

[0088] Fifth step, before the insulating component 800 is about to be inserted into the stator 700, the drive assembly 360 of the extrusion mechanism drives the extrusion block 350 to slide radially on the disk 340. The inner support bar 353 of the extrusion block 350 is gradually inserted into the sleeve 830 of the insulating component 800 and expands the inner width of the sleeve 830. Then, the arc-shaped extrusion surface 3521 of the extrusion block 350 radially extrudes the multiple arc-shaped partitions 821 of the insulating component 800, so that the outer diameter of the third annular body 820 formed by the multiple arc-shaped partitions 821 becomes smaller. Then, the Z-axis module 3202 drives the insulating component 800 to gradually insert downward into the stator 700.

[0089] When the arc-shaped partition 821 of the insulating component 800 and the jacket 830 are inserted downward into the stator 700 to a certain depth (the specific value is selected according to actual needs), the pressing block 350 withdraws from the insulating component 800 radially along the disc 340. Then the first telescopic component 334 extends, and the slide block 333 and the wedge block 336 move downward, causing the hook support 339 of the hook support unit 335 to open and disengage from the insulating component 800. The first telescopic component 334 continues to extend downward, driving the push rod 3314 to pass through the lower fixed seat 332 and press against the upper partition 832 of the jacket 830. The first telescopic component 334 pushes the insulating component 800 downward through the push rod 3314 until the insulating component 800 is inserted into the stator 700 to the required depth, and then retracts upward towards the first telescopic component 334.

[0090] like Figure 10 As shown, this embodiment also discloses an assembly device for stators and insulating components, including a turntable 900 and a feeding device 100, an assembly device 300, and a pressing device 400 arranged sequentially along the circumference of the turntable 900.

[0091] The turntable 900 is horizontally positioned and can rotate under the drive of an external drive. A conveyor belt 910 is provided on one side of the turntable 900, and the conveying direction of the conveyor belt 910 is configured in the X-axis direction. A tray is provided on the conveyor belt 910, and a stator 700 is provided on the tray. A robotic arm 920 for loading insulating components 800 is provided on the other side of the turntable 900. In this embodiment, the robotic arm 920 loads the insulating components 800 into the second positioning component 600.

[0092] The feeding device 100 is arranged between the turntable 900 and the production line 910 along the Y-axis direction. The feeding device 100 is used to feed the stator 700 on the production line 910 onto the turntable 900.

[0093] like Figure 11 As shown, the feeding device 100 includes a second frame 110, a Y-axis module 120, a first moving plate 130, and two inner support components 140. The second frame 110 is disposed between the turntable 900 and the line 910. The Y-axis module 120 is disposed on the second frame 110 and is used to drive the first moving plate 130 to move in the Y-axis direction. The two inner support components 140 are spaced apart on the first moving plate 130 along the Y-axis direction.

[0094] like Figure 12 As shown, the inner support assembly 140 includes a second Z-axis module 141, a second movable plate 142, an inner support gripper 143, a first pressure plate 144, and a second elastic element 145. The second Z-axis module 141 is disposed on the first movable plate 130, and the second movable plate 142 is disposed on the second Z-axis module 141. The second Z-axis module 141 can drive the second movable plate 142 to move in the Z-axis direction. The inner support gripper 143 is disposed on the second movable plate 142, and the inner support gripper 143 can be opened horizontally. When picking up the stator 700, the inner support gripper 143 can move to the top of the stator 700 and insert downward into the interior of the stator 700. The material is held in place inside the stator 700 to perform the material handling operation of the stator 700; the lower surface of the second moving plate 142 is provided with multiple second guide posts, which extend downward and slide through the first pressure plate 144, thereby restricting the first pressure plate 144 to move only in the Z-axis direction; the middle part of the second pressure plate 430 is provided with a sleeve hole, which is fitted onto the outer periphery of the inner support claw 143; the second elastic element 145 is configured as a spring, and the second elastic element 145 is fitted onto the outer periphery of the second guide post in a corresponding manner; the two ends of the second elastic element 145 are respectively connected to the first pressure plate 144 and the second moving plate 142, and the extension and retraction direction of the second elastic element 145 is configured in the Z-axis direction.

[0095] In this embodiment, the feeding device 100 is equipped with two inner support components 140. During feeding, the first inner support component 140 picks up the stator 700 on the tray by the drive of the Y-axis module 120 and the Z-axis module 141, and then moves laterally along the Y-axis to the upper side of the turntable 900. At this time, the second inner support component 140 picks up the stator 700 with the insulation component 800 already assembled on the turntable 900. The first inner support component 140 then places the stator 700 without the insulation component 800 assembled on the turntable 900. The second inner support component 140 then places the stator 700 with the insulation component 800 assembled on the tray and transports it forward with the line 910. By setting two inner support components 140 that can pick up materials alternately, this embodiment can greatly improve work efficiency. On the other hand, the inner support assembly 140 of this embodiment is also provided with a first pressure plate 144 and a second elastic member 145. When picking up the stator 700, the first pressure plate 144 can first contact the upper end surface of the stator 700 and elastically press the stator 700 onto the tray or onto the turntable 900. This ensures that the stator 700 is in a horizontal state when the inner support claw 143 holds the stator 700, and avoids the stator 700 from being unable to align with the positioning structure provided on the tray or turntable 900 when it is placed on the tray or on the turntable 900.

[0096] like Figure 13 and Figure 14 As shown, in some preferred embodiments, the assembly equipment further includes a first positioning component 500 disposed on the turntable 900. The first positioning component 500 includes a first fixed platform 510, a first slide 520, a centering block 530, and a second alignment block 540. The first fixed platform 510 is disposed on the turntable 900, and the first slide 520 is slidably disposed on the first fixed platform 510. The sliding direction of the first slide 520 is configured in the Z-axis direction. Both the turntable 900 and the first fixed platform 510 are provided with clearance through holes extending along the Z-axis direction to avoid the first lifting mechanism 200 or the second lifting mechanism 450 located below the turntable 900. There are multiple centering blocks 530; four are shown in this embodiment. The multiple centering blocks 530 are spaced apart on the first slide 520 around the Z-axis direction, forming a positioning circle for centering the stator 700. Figure 13As shown by the dotted line R, the positioning circle R is coaxial with the first annular body 710 of the stator 700. One side of each centering block 530 can abut against the spacer 720 of the stator 700, thereby centering the stator 700. In some preferred embodiments, a second chamfer is provided between the top surface and the side surface of the centering block 530. The second chamfer is preferably a rounded corner. The second chamfer facilitates the insertion of multiple centering blocks 530 into the stator 700. The second alignment block 540 is disposed on the first slide 520. When the stator 700 is placed downwards onto the first slide 520, the second alignment block 540 can be inserted into the spacer 720 of the stator 700 along the Z-axis direction, thereby restricting the rotation of the stator 700. In this embodiment, the upper end of the second alignment block 540 is preferably configured as a pointed tip. The pointed tip can be formed by the chamfer. The pointed tip facilitates the smooth insertion of the second alignment block 540 into the spacer 720 of the stator 700.

[0097] It should be noted that when the stator 700 needs to be lifted upward, the first lifting mechanism 200 or the second lifting mechanism 450 passes upward through the clearance through hole of the turntable 900 and lifts the first slide 520 upward, thereby lifting the stator 700 set on the first slide 520 upward. Since the stator 700 is restricted by the centering block 530 and the second alignment block 540, the stability of the stator 700 during the assembly process can be guaranteed.

[0098] like Figure 15 As shown, in this embodiment, the first lifting mechanism 200 is disposed on the lower side of the turntable 900. The first lifting mechanism 200 is coaxially corresponding to the disk 340 of the assembly device 300. The lifting direction of the first lifting mechanism 200 is configured as the Z-axis direction. The first lifting mechanism 200 can lift the stator 700 on the turntable 900 upward and coaxially lift the stator 700 into the receiving hole 340a of the disk 340.

[0099] like Figure 16 As shown, in this embodiment, the assembly device 300 is disposed on one side of the turntable 900. The disc 340 of the assembly device 300 is disposed above the turntable 900 via a support frame. The assembly device 300 presses the insulating component 800 into the stator 700.

[0100] like Figure 16 and Figure 17 As shown, in some preferred embodiments, the assembly equipment further includes a second positioning component 600, which is located on one side of the assembly device 300 along the X-axis direction.

[0101] like Figure 17 and Figure 18As shown, the second positioning component 600 includes a second fixed platform 610, a second slide 620, a rotary platform 630, a third telescopic member 640, a third alignment block 650, a fourth elastic member 660, and a rotary drive member 670. The second fixed platform 610 is located on one side of the disk 340 along the X-axis direction. The second slide 620 is slidably disposed on the second fixed platform 610, and the sliding direction of the second slide 620 is configured in the Z-axis direction. In this embodiment, multiple third guide posts are provided on the lower surface of the second slide 620. The third guide posts slide downward through the second fixed platform 610, thereby enabling the second slide 620 to slide only in the Z-axis direction. The fourth elastic member 660 is disposed between the second fixed platform 610 and the second slide 620. The two ends of the fourth elastic member 660 are respectively connected to the second slide 620 and the second fixed platform 610. The telescopic direction of the fourth elastic member 660 is configured in the Z-axis direction. The rotary platform 630... The rotary table 630 is rotatably mounted on the second slide table 620. The rotary table 630 can only rotate around the Z-axis and cannot undergo horizontal or vertical displacement. An annular positioning groove 630a is provided on the rotary table 630. The inner diameter of the annular positioning groove 630a is equal to the outer diameter of the third annular body 820 of the insulating component 800. A third telescopic component 640 is mounted on the second slide table 620, and its telescopic direction is configured horizontally. The third telescopic component 640 includes a telescopic cylinder or an electric push rod. A third alignment block 650 is located at the telescopic end of the third telescopic component 640, and its structure is consistent with the structure of the inner support bar 353 of the extrusion block 350. A rotary drive component 670, such as a motor, is mounted on the second slide table 620, and its output end is coaxially connected to the rotary table 630, driving the rotary table 630 to rotate.

[0102] The working principle of the second positioning component 600 in this embodiment is as follows:

[0103] The robotic arm 920 picks up the insulating component 800 from the material storage location and places it downwards along the Z-axis into the annular positioning groove 630a of the rotary table 630. The annular positioning groove 630a aligns the insulating component 800. After the insulating component 800 is placed in the annular positioning groove 630a, the third telescopic component 640 drives the third alignment block 650 to insert into the sleeve 830 of the insulating component 800. Since the width of the third alignment block 650 is equal to or slightly smaller than the inner width of the sleeve 830 (for example, the width of the third alignment block 650 is 0.95 to 0.99 times the inner width of the sleeve 830), this ensures that the insulating component 800 is properly aligned. The insulating element 800 is pushed and rotated by the third alignment block 650 at a certain angle to achieve angular positioning of the insulating element 800. In some preferred embodiments, the end of the third alignment block 650 can be designed with a chamfer so that the third alignment block 650 can be smoothly inserted into the sleeve 830. In this embodiment, a rotation drive 670 is also provided. If the third alignment block 650 is not smoothly inserted into the sleeve 830, the third telescopic member 640 will retract the third alignment block 650. Then, the rotation drive 670 will drive the rotary table 630 and the insulating element 800 to rotate at a certain angle, and the third alignment block 650 will be inserted into the sleeve 830 again.

[0104] In this embodiment, a fourth elastic element 660 is provided between the second slide 620 and the second fixed stage 610. When the material picking and placing assembly 330 of the assembly device 300 moves laterally along the X-axis to pick up the insulating component 800 above the rotary stage 630, the lower surface (horizontal reference surface) of the lower fixed seat 332 can press down on the insulating component 800 under the drive of the Z-axis module 3202 (the fourth elastic element 660 is under pressure at this time). Pressing down on the insulating component 800 makes the upper end surface of the insulating component 800 fit together with the lower surface of the lower fixed seat 332, ensuring that the insulating component 800 is in a horizontal state. On the other hand, the fit between the upper end surface of the insulating component 800 and the lower surface of the lower fixed seat 332 ensures that the insulating component 800 and the lower fixed seat 332 are in the correct relative position at this time. Only then can the hook support 339 of the hook support unit 335 accurately support the lower surface 811 of the second annular body of the insulating component 800, thereby completing the picking up of the insulating component 800.

[0105] like Figure 19As shown, the pressing device 400 includes a third frame 410, a pressing head column 420, a second pressure plate 430, a third elastic element 440, and a second lifting mechanism 450. The third frame 410 is disposed on the upper side of the turntable 900, and the pressing head column 420 is disposed on the third frame 410. The pressing head column 420 is cylindrical and can be inserted into the insulating element 800, and abuts against the clamp 830 inside the insulating element 800 in the Z-axis direction. The lower end of the third frame 410 is provided with multiple fourth guide columns. The fourth guide columns extend downward and slide through the second pressure plate 430, and pass through the fourth guide columns. The column restricts the second pressure plate 430 to slide only in the Z-axis direction; the third elastic element 440 is configured as a spring, and the third elastic element 440 is sleeved on the outer periphery of the fourth guide column. The two ends of the third elastic element 440 are respectively connected to the second pressure plate 430 and the third frame 410, and the extension and retraction direction of the third elastic element 440 is configured in the Z-axis direction; the second lifting mechanism 450 is set on the lower side of the turntable 900. The second lifting mechanism 450 is coaxially set with the pressure head column 420. The second lifting mechanism 450 can lift the stator 700 and the first slide table 520 on the turntable 900 upward.

[0106] In this embodiment, the second lifting mechanism 450 of the pressing device 400 can lift the stator 700 and the insulating component 800 upwards, so that the pressing head column 420 contacts the insulating component 800, thereby enabling deep pressing assembly of the insulating component 800 and the stator 700, and preventing the insulating component 800 from not being fully assembled in the assembly device 300 of the previous station.

[0107] The working principle of the pressing device 400 in this embodiment is as follows:

[0108] The second lifting mechanism 450 lifts the stator 700, which is equipped with the insulating component 800, upwards. During this upward movement, the second annular body 810 of the insulating component 800 pushes the second pressure plate 430 upwards, causing the third elastic component 440 to be compressed. Driven by the second lifting mechanism 450, the insulating component 800 continues to move upwards. The pressure head column 420 inserts into the second annular body 810 of the insulating component 800 and contacts the upper side of the clamp 830. Because the insulating component 800 and the stator 700 are continuously driven upwards by the second lifting mechanism 450, the pressure head... The column 420 can hold the insulating component 800, causing relative movement between the insulating component 800 and the stator 700, thereby pressing the insulating component 800 and the stator 700 together completely. After the second lifting mechanism 450 is lifted to a certain height, the second lifting mechanism 450 falls back down. Under the restoring force of the third elastic component 440, the second pressure plate 430 applies a downward force to the insulating component 800 and the stator 700, allowing the insulating component 800 and the stator 700 to detach from the pressure head column 420. Finally, the insulating component 800 and the stator 700 fall back onto the turntable 900.

[0109] like Figure 15 As shown in the figure, in this embodiment, the first lifting mechanism 200 and the second lifting mechanism 450 have the same structure, both including a lifting cylinder and a lifting platform. The lifting cylinder is located on the lower side of the turntable 900 and is connected to the lifting platform. The extension and retraction direction of the lifting cylinder is configured in the Z-axis direction. Under the drive of the lifting cylinder, the lifting platform can pass upward through the clearance hole on the turntable 900 and lift the first slide 520 and the stator 700 on the turntable 900 upward.

[0110] The working process of the assembly equipment in this embodiment is as follows:

[0111] In the first step, line 910 conveys the tray and stator 700 along the X-axis to one side of the feeding device 100;

[0112] In the second step, the feeding device 100 picks up the stator 700 on the tray and places it on the first positioning component 500 on the turntable 900;

[0113] Third step, turntable 900 rotates, stator 700 rotates to the working range of assembly device 300, first lifting mechanism 200 lifts stator 700 upward and lifts it into disc 340 of assembly device 300.

[0114] In the fourth step, the robotic arm 920 loads the insulating component 800 onto the second positioning component 600. Driven by the module integration 320, the picking and placing component 330 of the assembly device 300 picks up the insulating component 800 from the second positioning component 600 and moves the insulating component 800 to directly above the stator 700.

[0115] Fifth step: As the module integration 320 moves the insulating component 800 downward toward the stator 700, the extrusion block 350 of the extrusion mechanism extrudes the insulating component 800 so that the lower end of the insulating component 800 can be smoothly inserted into the stator 700.

[0116] In the sixth step, the push rod 3314 of the assembly device 300, driven by the first telescopic member 334, presses the insulating member 800 downward into the stator 700.

[0117] In the seventh step, the first lifting mechanism 200 drives the stator 700, which is equipped with the insulating component 800, to fall back onto the turntable 900. The turntable 900 rotates, and the stator 700 and the insulating component 800 rotate into the working range of the pressing device 400.

[0118] In the eighth step, the second lifting mechanism 450 of the pressing device 400 lifts the insulating component 800 and the stator 700 upwards, and presses the insulating component 800 completely into the stator 700 through the pressure head column 420. Then the second lifting mechanism 450 drives the insulating component 800 and the stator 700 to fall back onto the turntable 900.

[0119] In the ninth step, the turntable 900 rotates, and the stator 700 equipped with the insulating component 800 rotates to the working range of the feeding device 100. The feeding device 100 then transfers the stator 700 equipped with the insulating component 800 onto the tray of the line body 910.
