For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0019] This embodiment discloses an assembly device and equipment for a stator and an insulating member. To facilitate understanding of the technical solution of this embodiment, the structures of the stator 700 and the insulating member 800 in this embodiment are first introduced.

[0020] 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 circumferential wall of the first annular body 710. The axial thickness of the partition 720 is equal to that of the first annular body 710. The plurality of partitions 720 are arranged on the inner side of the first annular body 710 at equal intervals along the circumference of the first annular body 710. A winding groove 700a is formed between two circumferentially adjacent partitions 720 and the inner circumferential wall of the first annular body 710.

[0021] like Figure 2As shown, the insulating member 800 includes a second annular body 810, a third annular body 820 and a plurality of jackets 830. The lower surface 811 of the second annular body is a horizontal plane. The third annular body 820 is coaxially arranged 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 a plurality of arcuate partitions 821. The length direction of the arcuate partitions 821 is arcuate. The plurality of arcuate partitions 821 are evenly spaced along the circumference of the second annular body 810 on the lower surface 811 of the second annular body. The plurality of arcuate partitions 821 arranged at intervals form the third annular body 820. The width of the interval between two circumferentially adjacent arcuate partitions 821 is equal to the width of the partition 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 arranged on the third annular body 820 at equal intervals along the circumferential direction, and the sleeves 830 are arranged one-to-one with the partition 720, wherein the sleeve 830 includes two inner partitions 831 arranged opposite to each other along the circumference of the third annular body 820, and 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 the two adjacent arc-shaped partitions 821, and the interval 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 member 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 layer 832 , the two ends of which are respectively connected to the two inner partition layers 831 . When the stator 700 and the insulating member 800 are assembled, the upper partition layer 832 is in contact with the upper surface of the partition 720 .

[0022] like Figure 3 As shown, the assembly device 300 of this embodiment includes a material taking and placing mechanism and an extrusion 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 vertically to form a spatial coordinate system.

[0023] like Figure 3 As shown, the material taking and placing mechanism includes a first frame 310, a module assembly 320 and a material taking and placing assembly 330, which are specifically as follows: The first frame 310 is fixedly mounted on a workbench or other base surface to provide an installation location for the module assembly 320 .

[0024] The module integration 320 includes an X-axis module 3201 and a Z-axis module 3202. The X-axis module 3201 is set 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 picking and placing component 330 to move in the Z-axis direction.

[0025] like Figure 4 As shown, the material taking and placing assembly 330 includes an upper fixed seat 331, a lower fixed seat 332, a slide 333, a first telescopic member 334 and a plurality of hook support units 335 arranged around the Z-axis direction; the upper fixed seat 331 is connected to the Z-axis module 1 3202, and can be driven to move in the X-axis direction and the Z-axis direction through the X-axis module 3201 and the Z-axis module 1 3202; the upper fixed seat 331 and the lower fixed seat 332 are separated by a certain distance in the Z-axis direction, and the upper fixed seat 331 and the lower fixed seat 332 are fixedly connected by a mounting rod; the slide 333 is slidingly arranged between the upper fixed seat 331 and the lower fixed seat 332 along the Z-axis direction. For example, the slide 333 is slidingly arranged on the upper side of the lower fixed seat 332 through the first guide column; the first telescopic member 334 is arranged on the upper fixed seat 331, and 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 as the Z-axis direction, and the slide 333 is driven to move in the Z-axis direction by the first telescopic member 334. The first telescopic member 334 of this embodiment includes a telescopic cylinder or other actuator with linear telescopic capability.

[0026] like Figure 4 As shown, there are multiple hook support units 335 . In this embodiment, the preferred number of hook support units 335 is three, and the three hook support units 335 are arranged on the lower fixing seat 332 at equal intervals around the Z-axis direction.

[0027] 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 333 and can move along the Z axis with the slide 333. The wedge block 336 is provided with a driving inclined surface 3361. The driving inclined surface 3361 has a predetermined angle with the Z axis, and the predetermined angle ranges from 30 degrees to 80 degrees. The middle part of the lever 337 is hinged to the lower fixed base 3 32. The first end (i.e., the upper end) of the lever 337 is provided with a roller 338, and the outer peripheral surface of the roller 338 can be in rolling contact with the driving inclined surface 3361 of the wedge block 336. When the slide 333 drives the wedge block 336 to move downward along the Z-axis, the first end of the lever 337 rotates toward the slide 333 and approaches. Therefore, the hook support 339 on the second end of the lever will move away and release the constraint on the insulating member 800; the hook support 339 is provided on the lever 337. At the second end (i.e., the lower end) of 37, when the slide 333 drives the wedge block 336 to move upward along the Z-axis direction, under the action of the first elastic member 3310, the hook support member 339 moves toward the insulating member 800 and moves to the lower surface 811 of the second annular body of the insulating member 800. The hook support member 339 contacts the lower surface 811 of the second annular body and supports the insulating member 800 in the Z-axis direction, thereby realizing the material removal of the insulating member 800; the first elastic member 3310 is preferably a spring, and the two ends of the first elastic member 3310 are respectively connected to the lower fixed seat 332 and the lever 337. The extension direction of the first elastic member 3310 is configured to be horizontal. When the slide 333 drives the wedge block 336 to move downward along the Z-axis direction, the first elastic member 3310 will deform. After the deformation is compressed, the first elastic member 3310 has a tendency to push the second end of the lever 337 and the hook support member 339 toward the insulating member 800. In some preferred embodiments, the hook support member 339 is provided with a horizontal surface, which can be in contact with the lower surface 811 of the second annular body, that is, the hook support member 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.

[0028] like Figure 5 As shown, in this embodiment, a plurality of hook support units 335 are provided to support the insulating part 800 from multiple points to ensure the stability of the insulating part 800. The first telescopic part 334 can drive the slide 333 and the wedge block 336 to move, thereby simultaneously driving the levers 337 of the plurality of hook support units 335 to rotate with high synchronization, thereby ensuring the smooth progress of the assembly work. In addition, the hook support member 339 is used to support the second annular body 810 of the insulating part 800. The insulating part 800 will not be subjected to horizontal extrusion force, so that the insulating part 800 will not produce large deformation, thereby ensuring the success rate of assembly of the insulating part 800.

[0029] 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 fixed seat 332. The centering column 3311 is coaxially arranged with the lower fixed seat 332 and the first telescopic member 334. The centering column 3311 extends away from the lower fixed seat 332 along the Z-axis direction. The shape of the centering column 3311 is cylindrical. The outer diameter of the centering column 3311 is equal to the outer diameter of the second annular body 810 of the insulating member 800. When taking the material, the centering column 3311 Inserted downward into the second annular body 810 of the insulating member 800 to achieve forced centering with the insulating member 800, there are multiple first alignment blocks 3312, and multiple first alignment blocks 3312 are arranged at intervals along the circumference of the centering column 3311. The first alignment blocks 3312 can be arranged on the lower surface of the lower fixed seat 332 or on the outer circumferential surface of the centering column 3311, wherein an alignment groove 830a (such as Figure 2 As shown in the figure), when taking material downward along the Z-axis direction, the first alignment block 3312 corresponds to the alignment groove 830a in the Z-axis direction, and the first alignment block 3312 can be inserted downward into the alignment groove 830a, and 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, so the first alignment block 3312 can limit the rotation of the insulating part 800 around its axis.

[0030] In this embodiment, when the insulating part 800 is being taken out, the centering column 3311 is first used to ensure that it is in a coaxial state with the insulating part 800, the first alignment block 3312 limits the freedom of rotation of the insulating part 800, and finally the hook support 339 is used to limit the insulating part 800 from downwardly separating from the centering column 3311, which can ensure the position accuracy of the insulating part 800 after being taken out, thereby improving the success rate during assembly.

[0031] like Figure 4 and Figure 5 As shown, in some preferred embodiments, the material loading and unloading assembly 330 also includes a plurality of push rods 3314 connected to the slide 333, the upper end of the push rod 3314 is connected to the slide 333, and the lower end of the push rod 3314 is used to push the insulating part 800 downward, wherein the push rod 3314 is arranged in a one-to-one correspondence with the jacket 830 of the insulating part 800, and the push rod 3314 can push the upper side partition 832 of the jacket 830 downward so that the insulating part 800 is pressed downward onto the stator 700, and the lower fixed seat 332 is provided with a sliding hole corresponding to the push rod 3314, and the sliding hole passes through the lower fixed seat 332 along the Z-axis direction, and the sliding hole is used to avoid the push rod 3314.

[0032] In this embodiment, when the insulating member 800 is assembled on the stator 700, the insulating member 800 is deformed under the action of the extrusion block 350, so that the lower end of the insulating member 800 can be smoothly assembled on the stator 700. When the lower end of the insulating member 800 is fitted on the stator 700, the slide 333 moves downward, so that the wedge block 336 pushes the second end (i.e., the lower end) of the lever 337 away from the centering column 3311, and the hook support members 335 of the three hook support units 335 are moved away from the centering column 3311. 9 is in the open state and the insulating member 800 is released. During this process, although the push rod 3314 also moves downward with the slide 333, the push rod 3314 has not yet extended downward to the lower side of the lower fixed seat 332. Then, the slide 333 continues to move downward, and the push rod 3314 now extends downward to the lower side of the lower fixed seat 332 and pushes the upper side partition 832 of the jacket 830. The multiple push rods 3314 together push the insulating member 800 downward into the stator 700. In this embodiment, only one first telescopic member 334 is provided, which not only enables the removal and placement of the insulating member 800, but also enables the downward assembly of the insulating member 800. It should be noted that when the push rod 3314 contacts and presses down 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 cooperate with the vertical surface (the surface parallel to the Z axis) on the wedge block 336. At this time, even if the slide 333 and the wedge block 336 continue to move downward, they will not push the lever 337 to rotate, thereby preventing the wedge block 336 from excessively pushing the lever 337 to rotate.

[0033] like Figure 6 and Figure 7As shown, the extrusion mechanism includes a disc 340, an extrusion block 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 position of the disc 340. The receiving hole 340a is circular in shape, and the inner diameter of the receiving hole 340a is equal to the outer diameter of the first annular body 710 of the stator 700. There are multiple extrusion blocks 350, and the multiple extrusion blocks 350 are all slidably arranged on the disc 340. The sliding direction of the extrusion block 350 is configured as the radial direction of the disc 340. The extrusion block 350 can slide along the radial direction of the disc 340 and extend into the upper side of the receiving hole 340a. The extrusion block 350 is provided with an arc-shaped extrusion surface 3521 and an inner support bar 353 corresponding to the jacket 830. The arcuate extrusion surface 3521 of the block 350 can form a circular extrusion ring. Since the multiple extrusion blocks 350 can slide in the radial direction, the circular extrusion ring formed by the multiple arcuate extrusion surfaces 3521 can change the diameter. Before the insulating member 800 is assembled on the stator 700, the arcuate extrusion surface 3521 extrudes the arcuate spacer 821 of the insulating member 800 along the radial direction of the disk 340, so that the arcuate spacer 821 is deformed toward the axis of the insulating member 800. The multiple arcuate spacers 821 of the insulating member 800 are squeezed by the multiple arcuate extrusion surfaces 3521, so that the outer diameter of the third annular body 820 formed by the multiple arcuate spacers 821 becomes smaller, thereby ensuring that the third annular body 820 of the insulating member 800 can be smoothly inserted downward into the first annular body 710 of the stator 700.

[0034] like Figure 7 and Figure 8 As shown, the inner support bar 353 of this embodiment extends toward the axis of the disc 340. When the extrusion block 350 slides radially, the inner support bar 353 is inserted into the sleeve 830 of the insulating member 800 along the radial direction of the disc 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 expand the sleeve 830 and increase its width, so that the sleeve 830 can be smoothly inserted downward to both sides of the partition 720 of the stator 700.

[0035] 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 in the disc 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 and an electric push rod. For example, by setting a telescopic cylinder corresponding to the extrusion block 350 one by one, the extrusion block 350 can also be driven to slide radially in the disc 340.

[0036] like Figure 9As shown, in this embodiment, the extrusion block 350 includes a sliding body 351, a radial extrusion portion 352 and an inner support bar 353. The sliding body 351 is in the shape of a rectangular body. The disc 340 is provided with radial grooves corresponding to the extrusion blocks 350 (such as Figure 8 As shown in the figure, the length direction of the radial groove intersects perpendicularly with the axis of the disc 340; the sliding body 351 is slidably arranged in the radial groove, and the radial groove can limit the sliding body 351 to slide only in the radial direction of the disc 340; the middle position of the radial extrusion portion 352 is connected to the end of the sliding body 351, and one end face of the radial extrusion portion 352 facing the axis of the disc 340 is configured as an arc-shaped extrusion surface 3521, and the arc-shaped extrusion surface 3521 can be in contact with the outer peripheral surface of the arc-shaped partition 821, so that the arc-shaped partition 821 can be extruded 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.

[0037] like Figure 9 As shown, in some preferred embodiments, a first chamfer 3531 is provided at one end of the inner support bar 353 away from the radial extrusion portion 352. The first chamfer 3531 is configured to be formed by chamfering the end face and the horizontal side face of the inner support bar 353, and can be a rounded angle or an oblique angle. By providing the first chamfer 3531 at the end of the inner support bar 353 so that the width of the end position of the inner support bar 353 is smaller than the width at other positions, when the inner support bar 353 is inserted into the jacket 830, due to the smaller width of the end portion of the inner support bar 353, the inner support bar 353 can be inserted into the jacket 830 more smoothly, thereby avoiding the situation where the inner support bar 353 presses against the arc-shaped partition 821.

[0038] like Figure 9As shown, in some preferred embodiments, the inner support bar 353 has two side surfaces in its width direction, which are defined as a left side surface and a right side surface respectively. The left side surface and the right side surface are symmetrically arranged, and both the left side surface and the right side surface include an inner support surface 3532 and an avoidance surface 3533 connected to each other. The inner support surface 3532 is located below the avoidance surface 3533, wherein the width between the two inner support surfaces 3532 is greater than the inner width of the jacket 830. Therefore, when the inner support bar 353 is inserted into the jacket 830, the two inner support surfaces 3532 on the left and right can open the jacket 830 to increase the inner width of the jacket 830; the avoidance surface 3533 can be an arc surface or an inclined surface The avoidance surface 3533 is respectively connected to the inner support surface 3532 and the upper top surface of the inner support bar 353. When the inner support bar 353 is inserted into the jacket 830, although the avoidance surface 3533 is part of the side surface of the inner support bar 353, the avoidance surface 3533 does not contact the inner side surface of the jacket 830, that is, the avoidance surface 3533 does not contact the inner side of the inner partition 831. Therefore, when the inner support bar 353 is inserted into the jacket 830, the friction between the inner support bar 353 and the jacket 830 can be reduced, thereby effectively avoiding unnecessary deformation of the jacket 830 due to excessive friction, thereby avoiding adverse effects on the subsequent assembly of the jacket 830.

[0039] like Figure 6 As shown, in some preferred embodiments, the drive assembly 360 includes a drive disk 361, a drive wheel 362, a connecting member 363 and a second telescopic member 364; the drive disk 361 is circular in shape, and is rotatably arranged on the disk 340. The drive disk 361 is coaxially arranged with the disk 340, and the drive disk 361 is provided with a hole for facilitating the passage of the insulating member 800. The hole is coaxially corresponding to the accommodating 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, which is coaxially arranged with the disk 340, and 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 arranged in the rotating circular groove, and the drive disk 361 can rotate relative to the disk 340 in the rotating circular groove.

[0040] like Figure 7As shown, the driving disc 361 is provided with inclined grooves 361a corresponding to the extrusion blocks 350 one by one, and multiple inclined grooves 361a are arranged at equal intervals along the circumferential direction of the driving disc 361. The length direction of the inclined grooves 361a is tangent to the circumference of the driving disc 361. The inner width of the inclined grooves 361a is slightly larger than the outer diameter of the driving wheel 362, and the slightly larger width here can be 1.01 to 1.1 times; the driving wheels 362 are arranged in a one-to-one correspondence with the extrusion blocks 350, and the driving wheels 362 are rotatably arranged on the extrusion blocks 350, and the axial configuration of the driving wheels 362 is the Z-axis direction; the driving wheels 362 are arranged in a one-to-one correspondence in the inclined grooves 361a. When the driving disc 361 rotates, the inner sidewall of the inclined grooves 361a can push the driving wheels 362 During the radial movement of the disc 340, since the driving wheel 362 is connected to the extrusion block 350 and the extrusion block 350 can only slide in the radial direction, the extrusion block 350 slides in the radial direction when the driving disc 361 rotates; one end of the connecting member 363 is connected to the driving disc 361, and the other end of the connecting member 363 is hinged to the telescopic end of the second telescopic member 364. The second telescopic member 364 is fixedly arranged on the disc 340 or other external structure, and the telescopic direction of the second telescopic member 364 is configured to be tangential to the driving disc 361. Therefore, when the second telescopic member 364 is telescoped, the driving disc 361 can be driven to rotate through the connecting member 363; the second telescopic member 364 includes a linear telescopic element such as a telescopic cylinder or an electric push rod.

[0041] In this embodiment, the driving disk 361 is driven to rotate by the second telescopic member 364, and then all the extrusion blocks 350 can be synchronously driven to extrude the insulating member 800, ensuring that the insulating member 800 is evenly stressed when being squeezed. On the other hand, this method is easy to control, and the sliding amount of all the extrusion blocks 350 can be adjusted by simply controlling the expansion and contraction amount of the second telescopic member 364.

[0042] The working principle of the assembly device of the stator and the insulating member of this embodiment is as follows: The first step is to install the stator 700 in the receiving hole 340a of the disc 340; In the second step, the X-axis module 3201 drives the pick-up and unplacing assembly 330 to move above the insulating member 800, and the Z-axis module 1 3202 drives the pick-up and unplacing assembly 330 downward. When the pick-up and unplacing assembly 330 is a certain distance away from the insulating member 800, the first telescopic member 334 extends, and the lever 337 is pushed and rotated. The hook support member 339 at the lower end of the lever 337 moves away from the centering column 3311. At this time, the hook support members 339 of the three hook support units 335 are in an open state. In the third step, the Z-axis module 1 3202 drives the centering column 3311 downwardly into the insulating member 800. Simultaneously, the first alignment block 3312 is inserted into the alignment groove 830a of the insulating member 800. Then, the first telescopic member 334 retracts upward. Under the restoring force of the first elastic member 3310, the hook support members 339 of the three hook support units 335 simultaneously move toward the insulating member 800 and support the lower surface 811 of the second annular body of the insulating member 800. In the fourth step, the Z-axis module 1 3202 drives the pick-up and place assembly 330 connected to the insulating member 800 to be lifted to a certain height. Then, the X-axis module 3201 drives the pick-up and place assembly 330 and the insulating member 800 to move along the X-axis direction to just above the stator 700. The Z-axis module 1 3202 drives the insulating member 800 downward toward the stator 700. Step 5: Before the insulating member 800 is inserted into the stator 700, the drive assembly 360 of the extrusion mechanism drives the extrusion block 350 to slide radially in the disc 340. The inner support bar 353 of the extrusion block 350 gradually inserts into the jacket 830 of the insulating member 800, thereby increasing the inner width of the jacket 830. The arcuate extrusion surface 3521 of the extrusion block 350 then radially extrudes the multiple arcuate spacers 821 of the insulating member 800, reducing the outer diameter of the third annular body 820 formed by the multiple arcuate spacers 821. The Z-axis module 1 3202 then drives the insulating member 800 to gradually insert downward into the stator 700. When the arc-shaped partition 821 of the insulating part 800 and the sleeve 830 are inserted downward to a certain depth inside the stator 700 (the specific value is selected according to actual needs), the extrusion block 350 withdraws from the insulating part 800 along the radial direction of the disc 340, and then the first telescopic part 334 extends, and the slide 333 and the wedge block 336 move downward immediately, so that the hook support part 339 of the hook support unit 335 opens and disengages from the insulating part 800, and the first telescopic part 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 sleeve 830. The first telescopic part 334 pushes the insulating part 800 downward through the push rod 3314, and does not retract upward toward the first telescopic part 334 until the insulating part 800 is inserted into the stator 700 to the required depth.

[0043] like Figure 10 As shown, this embodiment further discloses an assembly device for a stator and an insulating member, comprising a turntable 900 and a loading device 100 , an assembly device 300 , and a press-fitting device 400 sequentially arranged along the circumference of the turntable 900 .

[0044] The turntable 900 is arranged horizontally and can rotate under the drive of an external driver. A wire body 910 is provided on one side of the turntable 900. The wire body 910 is conveyed in the X-axis direction. A tray is provided on the wire body 910, and the stator 700 is provided on the tray. A robot 920 for loading the insulating member 800 is also provided on the other side of the turntable 900. In this embodiment, the robot 920 loads the insulating member 800 to the second positioning assembly 600.

[0045] The loading device 100 is disposed between the turntable 900 and the wire body 910 along the Y-axis direction. The loading device 100 is used to load the stator 700 on the wire body 910 onto the turntable 900 .

[0046] like Figure 11 As shown, the loading device 100 includes a second frame 110, a Y-axis module 120, a first movable plate 130 and two internal support components 140. The second frame 110 is arranged between the turntable 900 and the line body 910, and the Y-axis module 120 is arranged on the second frame 110. The Y-axis module 120 is used to drive the first movable plate 130 to move in the Y-axis direction; the two internal support components 140 are arranged on the first movable plate 130 at intervals along the Y-axis direction.

[0047] like Figure 12 As shown, the inner support assembly 140 includes a Z-axis module 141, a second movable plate 142, an inner support clamping claw 143, a first pressure plate 144 and a second elastic member 145; the Z-axis module 141 is arranged on the first movable plate 130, and the second movable plate 142 is arranged on the Z-axis module 141. The Z-axis module 141 can drive the second movable plate 142 to move in the Z-axis direction; the inner support clamping claw 143 is arranged on the second movable plate 142, and the inner support clamping claw 143 can be stretched in the horizontal direction. When picking up the stator 700, the inner support clamping claw 143 can move to the top of the stator 700 and insert downward into the interior of the stator 700. The inner support clamping claw 143 It is tightly supported inside the stator 700 to realize the material removal work of the stator 700; a plurality of second guide pillars are provided on the lower surface of the second movable plate 142, and the second guide pillars extend downward and slide through the first pressure plate 144, thereby limiting the first pressure plate 144 to move only in the Z-axis direction, and a sleeve hole is provided in the middle of the second pressure plate 430, and the sleeve hole is sleeved on the outer peripheral side of the inner support clamp 143; the second elastic member 145 is configured as a spring, and the second elastic member 145 is sleeved on the outer periphery of the second guide pillar in a one-to-one correspondence. The two ends of the second elastic member 145 are respectively connected to the first pressure plate 144 and the second movable plate 142, and the extension and contraction direction of the second elastic member 145 is configured as the Z-axis direction.

[0048] In this embodiment, the loading device 100 is provided with two internal support components 140. During loading, the first internal support component 140 is driven by the Y-axis module 120 and the Z-axis module 141 to pick up the stator 700 on the tray, and then moves horizontally along the Y-axis direction to the upper side of the turntable 900. At this time, the second internal support component 140 picks up the stator 700 on the turntable 900 that has been assembled with the insulating part 800. The first internal support component 140 then places the stator 700 without the insulating part 800 on the turntable 900. The second internal support component 140 then places the stator 700 that has been assembled with the insulating part 800 on the tray and transports it forward with the line body 910. This embodiment can greatly improve work efficiency by providing two internal support components 140 that can alternately take materials. On the other hand, the internal 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 on the pallet or on the turntable 900. In this way, it can be ensured that the stator 700 is in a horizontal state when the internal support clamp 143 supports the stator 700, thereby preventing the stator 700 from being unable to align with the positioning structure provided on the pallet or turntable 900 when it is placed on the pallet or on the turntable 900.

[0049] like Figure 13 and Figure 14 As shown, in some preferred embodiments, the assembly equipment also includes a first positioning component 500 arranged on the turntable 900, and 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 arranged on the turntable 900, and the first slide 520 is slidably arranged on the first fixed platform 510, and the sliding direction of the first slide 520 is configured as the Z-axis direction; wherein, the turntable 900 and the first fixed platform 510 are both provided with avoidance through holes passing through along the Z-axis direction, for avoiding the first jacking mechanism 200 or the second jacking mechanism 450 located on the lower side of the turntable 900; there are multiple centering blocks 530, and four are shown in this embodiment. Multiple centering blocks 530 are arranged on the first slide 520 at intervals around the Z-axis direction, and the multiple centering blocks 530 form a positioning circle for centering the stator 700, and the positioning circle is as shown in FIG. Figure 13As shown by the dotted line R, the positioning circle R is coaxial with the first annular body 710 of the stator 700, wherein one side surface of each centering block 530 can be abutted against the partition 720 of the stator 700, thereby realizing the centering of the stator 700. In some preferred embodiments, a second chamfer is provided between the upper top surface and the side surface of the centering block 530. The second chamfer is preferably a rounded angle. The second chamfer facilitates the introduction of multiple centering blocks 530 into the stator 700; the second alignment block 540 is provided on the first slide 520. When the stator 700 is lowered onto the first slide 520, the second alignment block 540 can be inserted between the two partitions 720 of the stator 700 along the Z-axis direction to limit the rotation of the stator 700. In this embodiment, the upper end of the second alignment block 540 is preferably configured as a pointed end. The pointed end can be formed by the chamfer. The pointed end facilitates the smooth insertion of the second alignment block 540 between the two partitions 720 of the stator 700.

[0050] 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 through the avoidance hole of the turntable 900 and lifts the first slide 520 upward, and then lifts 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.

[0051] like Figure 15 As shown, the first lifting mechanism 200 in this embodiment is arranged on the lower side of the turntable 900, the first lifting mechanism 200 is coaxially corresponding to the disc 340 of the assembly device 300, and 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 accommodating hole 340a of the disc 340.

[0052] like Figure 16 As shown, the assembly device 300 of this embodiment is arranged on one side of the turntable 900 , and the disc 340 of the assembly device 300 is arranged above the turntable 900 through a support frame. The insulating member 800 is pressed into the stator 700 through the assembly device 300 .

[0053] like Figure 16 and Figure 17 As shown, in some preferred embodiments, the assembly equipment further includes a second positioning component 600 , and along the X-axis direction, the second positioning component 600 is located on one side of the assembly device 300 .

[0054] like Figure 17 and Figure 18As shown, the second positioning assembly 600 includes a second fixed platform 610, a second slide 620, a rotating platform 630, a third telescopic member 640, a third alignment block 650, a fourth elastic member 660 and a rotating driving member 670; the second fixed platform 610 is located on one side of the disk 340 along the X-axis direction, and the second slide 620 is slidably set on the second fixed platform 610, and the sliding direction of the second slide 620 is configured as the Z-axis direction. In this embodiment, a plurality of third guide pillars are provided on the lower surface of the second slide 620, and the third guide pillars slide downward through the second fixed platform 610, so that the second slide 620 can only slide in the Z-axis direction. The fourth elastic member 660 is provided between the second fixed platform 610 and the second slide 620, and the two ends of the fourth elastic member 660 are respectively connected to the second slide 620 and the second fixed platform 610, and the telescopic direction of the fourth elastic member 660 is configured as the Z-axis direction; the rotating platform 63 0 is arranged on the second slide 620, and the rotating table 630 can only rotate about the Z axis and cannot be displaced in the horizontal or height direction; an annular positioning groove 630a is provided on the rotating 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 member 800; the third telescopic member 640 is arranged on the second slide 620, and the telescopic direction of the third telescopic member 640 is configured to be horizontal, and the third telescopic member 640 includes a telescopic cylinder or an electric push rod; the third alignment block 650 is arranged at the telescopic end of the third telescopic member 640, and the structure of the third alignment block 650 is consistent with the structure of the inner support bar 353 of the extrusion block 350; the rotation driving member 670 is configured as a motor, etc., and the rotation driving member 670 is arranged on the second slide 620, and the output end of the rotation driving member 670 is coaxially connected to the rotating table 630, and the rotating table 630 is driven to rotate by the rotation driving member 670.

[0055] The working principle of the second positioning assembly 600 of this embodiment is as follows: The manipulator 920 picks up the insulating part 800 from the material storage position and places it downward along the Z-axis direction into the annular positioning groove 630a of the rotating table 630, and aligns the insulating part 800 through the annular positioning groove 630a. After the insulating part 800 is placed in the annular positioning groove 630a, the third telescopic part 640 drives the third alignment block 650 to be inserted into the jacket 830 of the insulating part 800. Since the width of the third alignment block 650 is equal to or slightly smaller than the inner width of the jacket 830, for example, the width of the third alignment block 650 is 0.95 times to 0.99 times the inner width of the jacket 830, so that the insulating part 800 is aligned with the center of the annular positioning groove 630a. The edge member 800 is pushed and rotated to a certain angle by the third alignment block 650 to achieve angular positioning of the insulating member 800. In some preferred embodiments, the end of the third alignment block 650 can be designed with a guide angle so that the third alignment block 650 can be smoothly inserted into the sleeve 830. In this embodiment, a rotating drive member 670 is also provided. If the third alignment block 650 is not smoothly inserted into the sleeve 830, the third telescopic member 640 retracts the third alignment block 650, and then the rotating drive member 670 drives the rotating table 630 and the insulating member 800 to rotate to a certain angle, and then the third alignment block 650 is inserted into the sleeve 830 again.

[0056] In this embodiment, a fourth elastic member 660 is provided between the second slide 620 and the second fixed table 610. When the pick-up and placement component 330 of the assembly device 300 moves horizontally along the X-axis direction to the top of the rotating table 630 to pick up the insulating part 800, the lower surface (horizontal reference surface) of the lower fixed seat 332 can press down the insulating part 800 under the drive of the Z-axis module 1 3202 (the fourth elastic member 660 is under pressure at this time). On the one hand, pressing down the insulating part 800 makes the upper end surface of the insulating part 800 fit together with the lower surface of the lower fixed seat 332 to ensure that the insulating part 800 is in a horizontal state. On the other hand, the upper end surface of the insulating part 800 fits together with the lower surface of the lower fixed seat 332 to ensure that the insulating part 800 and the lower fixed seat 332 are in the correct relative position at this time, so that the hook support member 339 of the hook support unit 335 can accurately support the lower surface 811 of the second annular body of the insulating part 800, thereby completing the material removal of the insulating part 800.

[0057] like Figure 19As shown, the pressing device 400 includes a third frame 410, a pressure head column 420, a second pressure plate 430, a third elastic member 440 and a second lifting mechanism 450; the third frame 410 is arranged on the upper side of the turntable 900, and the pressure head column 420 is arranged on the third frame 410. The pressure head column 420 is cylindrical and can be inserted into the insulating member 800 and abut against the jacket 830 on the inner side of the insulating member 800 in the Z-axis direction; a plurality of fourth guide columns are provided at the lower end of the third frame 410, and the fourth guide columns extend downward and slide through the second pressure plate 430, through the fourth guide column The column limits the second pressure plate 430 to slide only in the Z-axis direction; the third elastic member 440 is configured as a spring, and the third elastic member 440 is correspondingly sleeved on the outer periphery of the fourth guide column, and the two ends of the third elastic member 440 are respectively connected to the second pressure plate 430 and the third frame 410, and the extension and contraction direction of the third elastic member 440 is configured as the Z-axis direction; the second jacking mechanism 450 is arranged on the lower side of the turntable 900, and the second jacking mechanism 450 is coaxially arranged with the pressure head column 420, and the stator 700 and the first slide 520 on the turntable 900 can be lifted upward by the second jacking mechanism 450.

[0058] In this embodiment, the second lifting mechanism 450 of the pressing device 400 can lift the stator 700 and the insulating part 800 upward, so that the pressing head column 420 contacts the insulating part 800, and then the insulating part 800 and the stator 700 can be deeply crimped and assembled, thereby avoiding the insulating part 800 from being completely assembled in the assembly device 300 of the previous workstation.

[0059] The working principle of the press-fitting device 400 in this embodiment is as follows: The second lifting mechanism 450 lifts the stator 700 equipped with the insulating member 800 upward. During the upward movement of the insulating member 800, the second annular body 810 of the insulating member 800 pushes the second pressure plate 430 upward, so that the third elastic member 440 is compressed. The insulating member 800 continues to move upward under the drive of the second lifting mechanism 450. The pressure head column 420 is inserted into the second annular body 810 of the insulating member 800 and contacts the upper side of the jacket 830. Since the insulating member 800 and the stator 700 are continuously driven upward by the second lifting mechanism 450, the pressure head The column 420 can support the insulating part 800 so that the insulating part 800 and the stator 700 move relative to each other, thereby making the insulating part 800 and the stator 700 completely pressed together. After the second lifting mechanism 450 is lifted to a certain height, the second lifting mechanism 450 falls back downward. Under the action of the reset force of the third elastic part 440, the second pressure plate 430 gives the insulating part 800 and the stator 700 a downward force, so that the insulating part 800 and the stator 700 can be separated from the pressure head column 420. Finally, the insulating part 800 and the stator 700 fall back onto the turntable 900 again.

[0060] like Figure 15As shown, in this embodiment, the first jacking mechanism 200 and the second jacking mechanism 450 have the same structure, both including a jacking cylinder and a jacking platform. The jacking cylinder is arranged on the lower side of the turntable 900, and the jacking cylinder is connected to the jacking platform. The telescopic direction of the jacking cylinder is configured as the Z-axis direction. Driven by the jacking cylinder, the jacking platform can pass upward through the avoidance hole on the turntable 900 and lift the first slide 520 and the stator 700 on the turntable 900 upward.

[0061] The working process of the assembly equipment of this embodiment is as follows: In the first step, the line body 910 transports the tray and the stator 700 along the X-axis direction to one side of the loading device 100; In the second step, the loading device 100 picks up the stator 700 on the tray and places it on the first positioning assembly 500 on the turntable 900; In the third step, the turntable 900 rotates, and the stator 700 rotates into the working range of the assembly device 300. The first lifting mechanism 200 lifts the stator 700 upward and lifts it into the disc 340 of the assembly device 300. In the fourth step, the robot 920 loads the insulating member 800 onto the second positioning assembly 600. Driven by the module assembly 320, the pick-up and place assembly 330 of the assembly device 300 picks up the insulating member 800 from the second positioning assembly 600 and moves the insulating member 800 to the position directly above the stator 700. In step 5, as the module assembly 320 drives the insulating member 800 downward toward the stator 700, the extrusion block 350 of the extrusion mechanism extrudes the insulating member 800 so that the lower end of the insulating member 800 can be smoothly inserted into the stator 700. In step 6, 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 ; In the seventh step, the first lifting mechanism 200 drives the stator 700 equipped with the insulating member 800 to fall back onto the turntable 900. The turntable 900 rotates, and the stator 700 and the insulating member 800 rotate into the working range of the press-fitting device 400. In step 8, the second lifting mechanism 450 of the press-fitting device 400 lifts the insulating member 800 and the stator 700 upward, and completely press-fits the insulating member 800 into the stator 700 via the press head column 420. The second lifting mechanism 450 then drives the insulating member 800 and the stator 700 back onto the turntable 900. In the ninth step, the turntable 900 rotates, and the stator 700 equipped with the insulating member 800 rotates to the working range of the loading device 100 . The loading device 100 transfers the stator 700 equipped with the insulating member 800 to the tray of the wire body 910 .
