The conveying guide member has a second hollow part for the output end of the jacking driving member to pass through. The carrying block is installed on the conveying guide member and has a third hollow part. The conveying driving member directly or indirectly drives the carrying block to move along the first direction so that the projection of the third hollow part in the vertical direction overlaps the output end of the jacking driving member. A first carrying mechanism and a second carrying mechanism are respectively located at two ends of the conveying guide member in the first direction.

[0016] Reference is made to Figure 1 andFigure 2 The iron core into shaft into magnetic ring machine provided by the embodiment of the present application comprises a rack 100, a press-fitting device 200, a press-fitting conveying mechanism 300, a first carrying mechanism 410 and a second carrying mechanism 420. The rack 100 has a first direction X, a second direction Y and a vertical direction Z which are perpendicular to each other.

[0017] In combination Figure 4 The press-fitting device 200 comprises a press-fitting support 210, a downward pressing driving member 220, a jacking driving member 230, a clamping driving member 240 and a press-fitting head 250. The press-fitting support 210 comprises a press-fitting bottom plate 211 and a press-fitting top plate 212. The press-fitting bottom plate 211 is installed on the rack 100. The press-fitting top plate 212 is located above the press-fitting bottom plate 211 and is connected with the press-fitting bottom plate 211 through a press-fitting stand 213. The press-fitting bottom plate 211 has a first hollow part 214 (see Figure 5 ) for the output shaft of the jacking driving member 230 to pass through. The jacking driving member 230 is installed on the rack 100. The downward pressing driving member 220 is installed on the press-fitting top plate 212. The press-fitting head 250 is installed on the output end of the downward pressing driving member 220. The press-fitting head 250 and the output end of the jacking driving member 230 are coaxially arranged above and below the motor shaft 10. The clamping driving member 240 is installed on the press-fitting head 250. The clamping driving member 240 is used for horizontally clamping the motor shaft 10 to ensure the stability of the motor shaft 10 in the XY plane.

[0018] In combination Figure 7 and Figure 8 The press-fitting conveying mechanism 300 comprises a conveying driving member 310, a conveying guide 320 and a carrying block 330. The conveying guide 320 is installed on the rack 100 and extends along the first direction X and across the press-fitting bottom plate 211. The conveying guide 320 has a second hollow part 321 for the output end of the jacking driving member 230 to pass through. The carrying block 330 is installed on the conveying guide 320. The carrying block 330 has a third hollow part 331. The conveying driving member 310 directly or indirectly drives the carrying block 330 to move along the first direction X so that the projection of the third hollow part 331 on the vertical direction Z overlaps with the output end of the jacking driving member 230.

[0019] Referring back to Figure 1 and Figure 2 The first carrying mechanism 410 and the second carrying mechanism 420 are respectively located at the two ends of the conveying guide 320 in the first direction X. The first carrying mechanism 410 is used for carrying the magnetic ring assembly 30 and the iron core piece 20 to the carrying block 330. The second carrying mechanism 420 is used for carrying the motor shaft 10 to the carrying block 330.

[0020] Specifically, refer to Figure 3First, driven by the transmission drive 310, the carrier block 330 moves along the first direction X to the second transport mechanism 420. The second transport mechanism 420 transports the motor shaft 10 to the carrier block 330, and the carrier block 330 moves the motor shaft 10 along the first direction X to below the press-fitting head 250. Second, the press-fitting head 250 and the output end of the lifting drive 230 clamp the motor shaft 10 vertically. The clamping drive 240 is used to horizontally clamp the motor shaft 10, and the output end of the lifting drive 230 descends to clamp and secure the motor shaft 10 to the press-fitting device 200. Third, driven by the transmission drive 310, the carrier block 330 moves along the first direction X to the first transport mechanism 410, receives the core member 20 and the magnetic ring assembly 30, and moves the core member 20 to below the press-fitting head 250. Fourth, the output end of the lifting drive member 230 rises, passes through the first hollow portion 214 of the press-fitting base plate 211, the second hollow portion 321 of the conveying guide member 320, and the third hollow portion 331 of the carrier block 330, and rests against the bottom end of the motor shaft 10. Together with the press-fitting head 250, the output end of the lifting drive member 230 clamps the motor shaft 10 from top to bottom, and then descends synchronously to press the motor shaft 10 into the iron core member 20 below, thereby completing the assembly of the motor shaft 10 and the iron core member 20. Fifth, similar to the assembly of the iron core, the carrier block 330 moves the magnetic ring assembly 30 to directly below the press-fitting head 250. The output end of the lifting drive member 230 and the press-fitting head 250 clamp the motor shaft 10 from top to bottom, and then descends synchronously to press the motor shaft 10 into the magnetic ring assembly 30, thereby completing the assembly of the motor shaft 10 and the magnetic ring assembly 30.

[0021] Based on this, the iron core into shaft into magnetic ring machine realizes the automatic assembly of the motor shaft 10, the iron core part 20 and the magnetic ring assembly 30, without the need for separate assembly in different equipment or manual assembly, reducing transportation time and improving production efficiency.

[0022] In some embodiments, combined Figure 4 The lifting drive member 230 plays the role of lifting the motor shaft 10 during the press-fitting process, preventing the motor shaft 10 from shaking and ensuring that the motor shaft 10 is coaxially press-fitted with the magnetic ring assembly 30 and the core member 20. The output end of the lifting drive member 230 is connected to a first push rod 231, and the end of the first push rod 231 is provided with a first positioning cone 232 for positioning the end of the embedded motor shaft 10. The vertex of the first positioning cone 232 can be embedded in the end groove of the motor shaft 10 of different specifications, and the conical side surface of the first positioning cone 232 increases the contact with the end of the motor shaft 10, further limiting the displacement of the motor shaft 10 in the horizontal plane.

[0023] In some embodiments, combined Figure 4The jacking driving member 230 is connected with a hollow first guide cylinder 233, the top end of the first guide cylinder 233 is installed on the pressing bottom plate 211, the first guide cylinder 233 and the pressing head 250 are coaxially arranged in the vertical direction Z, and the first guide cylinder 233 is used for guiding the first jack 231 to pass through the first hollow part 214 in the vertical direction Z. The first guide cylinder 233 directly limits the first jack 231 to move only in the vertical direction Z, completely eliminates the transverse deviation or inclination of the first jack 231 caused by uneven jacking force, too large length-diameter ratio, easy bending or slight deviation of the jacking driving member 230.

[0024] In some embodiments, in combination Figure 5 and Figure 6 The pressing head 250 includes a pressing cylinder body 251 and a second jack 252, the pressing cylinder body 251 is installed on the output end of the lower pressing driving member 220, and the second jack 252 is installed on the pressing cylinder body 251. The end of the second jack 252 is provided with a second positioning cone 253 used for positioning the end part of the motor shaft 10. The vertex of the second positioning cone 253 can be embedded into the end groove of the motor shaft 10 of different specifications, and the contact with the end part of the motor shaft 10 is increased through the tapered side surface of the second positioning cone 253, further limiting the displacement of the motor shaft 10 in the horizontal plane, realizing automatic centering and eliminating the coaxiality error.

[0025] In one of the embodiments, the pressing cylinder body 251 has a positioning sleeve hole 254, the positioning sleeve hole 254 is used for movably sleeving the outer periphery of the end part of the motor shaft 10, can form annular constraint from the radial direction of the motor shaft 10, and forcibly corrects the motor shaft 10 to the position coaxial with the pressing head 250.

[0026] In one of the embodiments, the second jack 252 is installed in the positioning sleeve hole 254, after the motor shaft 10 enters the positioning sleeve hole 254, the circumferential position of the motor shaft 10 is stable, which is beneficial to the alignment of the axis of the second jack 252 with the axis of the motor shaft 10. The positioning sleeve hole 254 not only bears the radial guidance of the motor shaft 10, but also provides a natural installation reference and support for the second jack 252.

[0027] In one of the embodiments, in combination Figure 5 and Figure 6 The pressing head 250 further includes a lower pressing elastic member 255, one end of the lower pressing elastic member 255 is installed on the hole bottom of the positioning sleeve hole 254, and the other end of the lower pressing elastic member 255 is installed on the top of the second jack 252. When the end part of the motor shaft 10 contacts the second jack 252, the lower pressing elastic member 255 will be compressed with the slight retreat of the second jack 252, and the impact force in the butt joint is automatically offset through the elastic force.

[0028] In addition, in one aspect, if the motor shaft 10 is unevenly stressed during pressing, the downward elastic member 255 can be slightly compressed on one side and remain the original length on the other side, driving the second jacking rod 252 to slightly adjust the height, so as to ensure that the motor shaft 10 is always stressed in the vertical direction Z. On the other hand, if the motor shaft 10 has a slight radial deviation due to errors, the elastic force of the downward elastic member 255 can be transmitted to the motor shaft 10 through the second jacking rod 252, cooperating with the radial constraint of the positioning sleeve hole 254, slowly correcting the motor shaft 10 to the coaxial position, avoiding the problem of bias caused by error accumulation.

[0029] In one embodiment, the pressing head 250 is provided with a clamping driving member 240, and the output end of the clamping driving member 240 is connected with a clamping block 241. Figure 6 The clamping driving member 240 drives the clamping block 241 to move in the radial direction of the pressing head 250, so as to realize the circumferential limiting of the motor shaft 10, and will not interfere with the axial stress of the motor shaft 10. In addition, the clamping driving member 240 controls the size of the clamping force and adapts to the motor shaft 10 with different outer diameters by controlling the movement distance of the clamping block 241 in the radial direction.

[0030] In one embodiment, the clamping block 241 has a clamping shaft notch 242, and the opposite inner walls of the clamping shaft notch 242 are used to abut against the outer wall of the motor shaft 10, so as to disperse the clamping force to two contact areas, further limiting the rotation and deviation of the motor shaft 10 in the radial direction.

[0031] In one embodiment, the pressing head 250 is provided with a clamping driving member 240, and the output end of the clamping driving member 240 is connected with a clamping block 241. Figure 5 and Figure 6 The bottom of the pressing head 250 is provided with a clamping positioning block 260, and the clamping positioning block 260 has a first containing through hole 261 for containing the motor shaft 10. The clamping positioning block 260 also has a second containing through hole 262, one end of the second containing through hole 262 communicates with the first containing through hole 261, and the other end of the second containing through hole 262 penetrates through the outer side wall of the clamping positioning block 260 in the radial direction of the pressing head 250, and the second containing through hole 262 is used for the radial movement of the clamping block 241. The first containing through hole 261 limits the circumferential position of the motor shaft 10, further avoids the axis deviation of the motor shaft 10, and at the same time ensures that the clamping block 241 will not cause the axis swing of the motor shaft 10 when clamping the motor shaft 10. The second containing through hole 262 provides rigid guide for the radial movement of the clamping block 241, and improves the movement stability of the clamping block 241. The clamping block 241 is completely hidden in the second containing through hole 262, avoiding external interference to the clamping block 241.

[0032] In one embodiment, the pressing head 250 is provided with a clamping driving member 240, and the output end of the clamping driving member 240 is connected with a clamping block 241. Figure 6 The number of clamping driving members 240 is two, and the two clamping driving members 240 are oppositely arranged in the radial direction of the pressing head 250, so that the output ends of the two clamping driving members 240 are folded towards each other to form a symmetrical clamping force, avoiding the stress deviation of the motor shaft 10.

[0033] In one of the embodiments, the pressing head 250 is provided with a positioning rod 270, which extends downward along the vertical direction Z and is exposed below the pressing head 250. The positioning rod 270 is used for positioning the iron core 20 and preventing the iron core from rotating during the pressing process. In particular, when the motor shaft 10 is assembled with multiple iron cores 20 or the iron core and the magnetic ring assembly 30 are continuously pressed, the positioning rod 270 keeps the circumferential positioning of the first iron core 20 between multiple pressing processes, thereby avoiding the deviation of the iron core installation angle. Figure 6 The side surface of the pressing head 250 is provided with a mounting plane 256, and the clamping driving member 240 is mounted on the mounting plane 256. The mounting plane 256 provides a mounting reference for the clamping driving member 240, and the plane contact area is large, thereby improving the mounting stability of the clamping driving member 240.

[0034] In one of the embodiments, the pressing head 250 is provided with a positioning rod 270, which extends downward along the vertical direction Z and is exposed below the pressing head 250. The positioning rod 270 is used for positioning the iron core 20 and preventing the iron core from rotating during the pressing process. In particular, when the motor shaft 10 is assembled with multiple iron cores 20 or the iron core and the magnetic ring assembly 30 are continuously pressed, the positioning rod 270 keeps the circumferential positioning of the first iron core 20 between multiple pressing processes, thereby avoiding the deviation of the iron core installation angle.

[0035] In one of the embodiments, the pressing device 200 further comprises a first photoelectric sensor 281, which is mounted on the pressing column 213 and detects the carrier block 330 in the second direction Y. The detection height of the first photoelectric sensor 281 is 5 mm to 50 mm higher than the top surface of the carrier block 330. The first photoelectric sensor 281 is used for detecting whether the carrier block 330 carries the components to be assembled, thereby facilitating the confirmation of whether the jacking driving member 230 and the pressing driving member 220 are started. During the pressing process, metal scraps, dust and other sundries may be generated. If the detection height is less than 5 mm, the accumulation of the sundries may easily trigger false detection.

[0036] In one of the embodiments, the pressing device 200 further comprises a second photoelectric sensor 282, which is mounted on the pressing column 213 and detects whether the pressing head 250 is lowered to a preset height in the second direction Y. When the pressing head 250 is lowered to the preset height, the second sensor detects the pressing head 250 and immediately sends a signal to the controller, thereby triggering the pressing head 250 to stop lowering or switching actions (such as from “fast downward movement” to “slow pressing”). This avoids the damage of the components caused by the excessive downward movement of the pressing head 250, thereby greatly reducing the defective product rate and equipment maintenance cost.

[0037] In one of the embodiments, the pressing device 200 further comprises a first photoelectric sensor 281, which is mounted on the pressing column 213 and detects the carrier block 330 in the second direction Y. The detection height of the first photoelectric sensor 281 is 5 mm to 50 mm higher than the top surface of the carrier block 330. The first photoelectric sensor 281 is used for detecting whether the carrier block 330 carries the components to be assembled, thereby facilitating the confirmation of whether the jacking driving member 230 and the pressing driving member 220 are started. During the pressing process, metal scraps, dust and other sundries may be generated. If the detection height is less than 5 mm, the accumulation of the sundries may easily trigger false detection. Figure 2 The pressing device 200 further comprises a code reader 283, which is mounted on the pressing column 213 and is used for scanning the motor shaft 10 on the carrier block 330. After the code reader 283 scans the code of the motor shaft 10, on one hand, the pressing device 200 can select appropriate pressing force and pressing depth; on the other hand, the code reader 283 can assist in realizing the automatic statistics of production data.

[0038] In one of the embodiments, the pressing device 200 further comprises a first photoelectric sensor 281, which is mounted on the pressing column 213 and detects the carrier block 330 in the second direction Y. The detection height of the first photoelectric sensor 281 is 5 mm to 50 mm higher than the top surface of the carrier block 330. The first photoelectric sensor 281 is used for detecting whether the carrier block 330 carries the components to be assembled, thereby facilitating the confirmation of whether the jacking driving member 230 and the pressing driving member 220 are started.

Figure 4The press-fitting device 200 further comprises a pressure sensor 284 mounted on the press-fitting head 250, which is used to detect the press-fitting force of the press-fitting head 250. The pressure sensor 284 can collect the force value changes in real time during the press-fitting process and feed back the data to the controller, so as to ensure that the press-fitting force is always within the preset process interval and guarantee the consistency of the assembly quality. The pressure sensor 284 records the force-displacement curve throughout the process and is stored in a bound manner with the identity information of the motor shaft 10 (obtained through the code reader 283). The production management personnel can analyze the batch force value curve to optimize the process parameters (such as adjusting the press-fitting speed and correcting the target force value), for example, find that the average press-fitting force of a batch of motor shafts 10 is too high, which can be traced back to the large shaft diameter tolerance, and then feedback to the upstream processing link for adjustment.

[0039] In some embodiments, in combination with Figure 2 and Figure 4 The number of press-fitting conveying mechanisms 300 is at least two, and the at least two press-fitting conveying mechanisms 300 are parallel and spaced apart along the second direction Y to realize parallel operation and greatly improve the production capacity per unit time.

[0040] In one of the embodiments, each press-fitting conveying mechanism 300 corresponds to a pressing driving member 220, a lifting driving member 230, a clamping driving member 240, and a press-fitting head 250. When each press-fitting conveying mechanism 300 is matched with an independent press-fitting head 250, the multiple press-fitting conveying mechanisms 300 realize synchronous independent operation without interference. The pressing driving member 220, the lifting driving member 230, the clamping driving member 240, and the press-fitting head 250 share one press-fitting support 210, which reduces the volume of the press-fitting device 200 and improves the integrity and modularity of the press-fitting device 200.

[0041] Specifically, the number of press-fitting conveying mechanisms 300 is two, and the two ends of the two press-fitting conveying mechanisms are aligned in the first direction X. Correspondingly, the number of pressing driving members 220, lifting driving members 230, clamping driving members 240, and press-fitting heads 250 is two. The first conveying mechanism 410 and the second conveying mechanism 420 can convey two components at the same time, that is, the first conveying mechanism 410 simultaneously grabs two core members 20 and places them on the carrying blocks 330 of the two press-fitting conveying mechanisms, simultaneously grabs two magnetic ring assemblies 30 and places them on the carrying blocks 330 of the two press-fitting conveying mechanisms, and the second conveying mechanism 420 simultaneously grabs two motor shafts 10 and places them on the carrying blocks 330 of the two press-fitting conveying mechanisms. Alternatively, the two pressing driving members 220, lifting driving members 230, and clamping driving members 240 move synchronously, which can make the power output and mechanical stress of the two workstations more balanced and avoid the problem of uneven wear of the press-fitting device 200 caused by the long-term bearing of larger load by a single workstation.

[0042] In some embodiments, in combination with Figure 2、 Figure 7 and Figure 8 The carrying block 330 comprises a first conveying block 340 and a second conveying block 350, the first conveying block 340 and the second conveying block 350 are sequentially distributed along the first direction X, the first conveying block 340 is closer to the first conveying mechanism 410 than the second conveying block 350, the first conveying block 340 is used for placing the magnetic ring assembly 30 and the at least two core pieces 20, and the first conveying block 340 is provided with at least two core positioning pin groups 341 and one magnetic ring positioning hole 342 which are sequentially and separately spaced along the first direction X. Wherein, the first conveying block 340 and the second conveying block 350 both have the third hollow part 331.

[0043] Therefore, the first conveying mechanism 410, the press-fitting device 200 and the second conveying mechanism 420 are spaced along the first direction X, the first conveying block 340 is used for interfacing with the first conveying mechanism 410, and the second conveying block 350 is used for interfacing with the second conveying mechanism 420, so as to shorten the sliding stroke of the carrying block 330 and improve the work efficiency. The core positioning pin groups 341 avoid the rotation deviation of the core pieces 20 during the movement of the carrying block 330, and the magnetic ring positioning hole 342 realizes the accurate positioning of the magnetic ring assembly 30 on the first conveying block 340.

[0044] Specifically, the core positioning pin groups 341 are two cylindrical pins which are diagonally distributed.

[0045] In one of the embodiments, the magnetic ring positioning hole 342 is located at the end of the first conveying block 340 close to the first conveying mechanism 410, matching the assembly sequence of the rotor assembly. Therefore, the first conveying block 340 moves along the first direction X close to the press-fitting head 250, and the core pieces 20 are sequentially assembled to the motor shaft 10, and finally the magnetic ring assembly 30 is assembled to the motor shaft 10.

[0046] In one of the embodiments, all the core positioning pin groups 341 are sequentially and vertically deflected at a preset angle, so that the plurality of core pieces 20 are staggered and press-fitted to the same motor shaft 10 at a preset angle.

[0047] In one of the embodiments, the second conveying block 350 is used for placing the motor shaft 10, and the motor shaft 10 is separately fed with the core pieces 20.

[0048] In some embodiments, the conveying driving member 310 comprises a first driving member 311 and a second driving member 312, the first driving member 311 is used for driving the first conveying block 340, and the second driving member 312 is used for driving the second conveying block 350. Independent driving allows the first conveying block 340 and the second conveying block 350 to move in parallel, improving the press-fitting efficiency.

[0049] In one of the embodiments, in combination with Figure 7The first driving member 311 and the second driving member 312 are respectively located on opposite sides of the conveying guide 320 in the second direction Y. On the one hand, the first driving member 311 and the second driving member 312 are located on opposite sides of the conveying guide 320. The forces generated during driving will offset each other in the second direction Y, resulting in a balanced force on the entire conveying guide 320 without any additional eccentric torque. On the other hand, the design of the first driving member 311 and the second driving member 312 on both sides can disperse the installation space of the first driving member 311 and the second driving member 312 to the left and right sides of the conveying guide 320, fully utilizing the space in the second direction Y.

[0050] In one embodiment, the combination Figure 7 The conveying guide 320 is a slide rail, and the conveying drive 310 drives the carrying block 330 to slide along the first direction X. The conveying guide 320 is stationary, and the second hollow portion 321 is stationary, maintaining vertical overlap with the first hollow portion 214. It is understood that in other embodiments, the conveying guide 320 is a conveyor belt, and the conveying drive 310 drives the conveyor belt to rotate, thereby driving the carrying block 330 to move along the first direction X. The second hollow portion 321 of the conveying guide 320 and the third hollow portion 331 of the carrying block 330 overlap vertically, and together move along the first direction X until they overlap vertically with the first hollow portion 214, thereby allowing the output end of the lifting drive 230 to pass through.

[0051] In some embodiments, combined Figure 1 and Figure 2 The first transport mechanism 410 is a first manipulator, which improves the coverage of the operating range and facilitates flexible grasping of the core piece 20 and the magnetic ring assembly 30. The second transport mechanism 420 is a second manipulator, which improves the coverage of the operating range and facilitates flexible grasping of the motor shaft 10.

[0052] In some embodiments, combined Figure 1 and Figure 2 The iron core into shaft into magnetic ring machine includes a shaft loading mechanism 510 installed on the frame 100, which realizes automatic loading of the motor shaft 10 and improves production efficiency.

[0053] In one embodiment, a shaft loading mechanism 510 is used to transport a shaft insertion plate 520 along the second direction Y. Multiple motor shafts 10 are inserted into the shaft insertion plate 520, enabling batch loading and significantly improving loading efficiency. This directly addresses the pain points of low loading efficiency and easy collision of individual shafts. The shaft loading mechanism 510 is located to one side of the press-fit conveyor mechanism 300 in the second direction Y, fully utilizing the space in the second direction Y, reducing the size of the device in the first direction X, and compressing the overall device footprint. Furthermore, the "loading area" is separated from the "main assembly area," preventing spatial overlap between the loading module and the press-fit conveyor mechanism 300.

[0054] Optionally, the core-into-shaft-into-magnetic-ring machine comprises a shaft feeding mechanism 510, which is connected to the shaft feeding mechanism 510 on the side of the shaft feeding mechanism 510 away from the press-fitting conveying mechanism 300, so as to avoid interference with the press fitting and to be away from the press-fitting working area, thereby facilitating protection of feeding safety.

[0055] In some embodiments, in combination with Figure 1 and Figure 2 , the shaft feeding mechanism 510, the second carrying mechanism 420, and the press-fitting conveying mechanism 300 are sequentially and spacedly distributed along the second direction Y. The second carrying mechanism 420 directly grabs the motor shaft 10 at the output end of the shaft feeding mechanism 510 without adjusting the grabbing direction, translates from the shaft feeding mechanism 510 to the press-fitting conveying mechanism 300 along the second direction Y, and only needs to move a short distance after grabbing to place the motor shaft 10 on the carrying block 330 of the press-fitting conveying mechanism 300, thereby improving work efficiency.

[0056] In one of the embodiments, the core-into-shaft-into-magnetic-ring machine further comprises a first visual detector 540 installed on the rack 100, the first visual detector 540 being located between the shaft feeding mechanism 510 and the press-fitting conveying mechanism 300, and the first visual detector 540 being used for detecting the appearance quality of the motor shaft 10. Based on this, the motor shaft 10 with appearance defects is intercepted in advance by the first visual detector 540 to avoid defective products flowing into subsequent processes and to ensure assembly quality. Moreover, the first visual detector 540 replaces manual visual detection to improve detection efficiency and consistency and to adapt to the automatic beat. The first visual detector 540 is located between the shaft feeding mechanism 510 and the press-fitting conveying mechanism 300, and the second carrying mechanism 420 needs to move to the press-fitting conveying mechanism 300 after grabbing the motor shaft 10 from the shaft feeding mechanism 510. The moving path passes through the detection area of the first visual detector 540, and the first visual detector 540 synchronously completes shooting and analysis, thereby improving detection efficiency.

[0057] In one of the embodiments, in combination with Figure 2 , the core-into-shaft-into-magnetic-ring machine further comprises a first recovery mechanism 550 installed on the rack 100, the movement track of the second carrying mechanism 420 passing through the first recovery mechanism 550, and the detection range of the first visual detector 540 covering the upper side of the first recovery mechanism 550. Based on this, the second carrying mechanism 420 needs to move to the press-fitting conveying mechanism 300 after grabbing the motor shaft 10 from the shaft feeding mechanism 510, and must pass through the first recovery mechanism 550. At this time, the motor shaft 10 is detected by the first visual detector 540. If qualified, the motor shaft 10 continues to move to the press-fitting conveying mechanism 300; if unqualified, the motor shaft 10 is placed in the first recovery mechanism 550 and returns to grab the next motor shaft 10, thereby improving the efficiency of feeding and detection.

[0058] In one of the embodiments, in combination with Figure 2, the first visual detector 540 and the first recycling mechanism 550 are distributed along the first direction X. The movement trajectory of the second conveying mechanism 420 needs to connect the taking shaft, detection, feeding of qualified shaft to compression assembly or feeding of unqualified shaft to recycling. If the first visual detector 540 and the first recycling mechanism 550 are distributed along the second direction Y, the second conveying mechanism 420 needs to stay continuously twice in the second direction Y, that is, first stay under the first visual detector 540 for detection, and then stay above the first recycling mechanism 550 for placing unqualified products, which increases the loading time cost. When the first visual detector 540 and the first recycling mechanism 550 are distributed along the first direction X, the second conveying mechanism 420 only needs to stay once between the first visual detector 540 and the first recycling mechanism 550. If the detection is qualified, the second conveying mechanism 420 continues to move, otherwise, the motor shaft 10 is recycled. The action path is more concise, and the beat conflict with other mechanisms is avoided.

[0059] In one of the embodiments, the motor shaft feeding mechanism 510, the first visual detector 540, the first recycling mechanism 550, the second conveying mechanism 420, the compression assembly conveying mechanism 300, the second visual detector 530, the second recycling mechanism 570, and the marking mechanism 560 are arranged on the rack 100. Figure 2 , the core into the shaft into the magnetic ring machine further comprises a marking mechanism 560 installed on the rack 100, and the marking mechanism 560 is used for marking the motor shaft 10 to realize information management in the production process.

[0060] In one of the embodiments, the marking mechanism 560 is located between the shaft feeding mechanism 510 and the compression assembly conveying mechanism 300. The marking action is embedded in the transfer gap, and a separate marking movement path does not need to be added for marking, thereby improving the operation efficiency.

[0061] Specifically, the marking mechanism 560 is located between the first visual detector 540 and the compression assembly conveying mechanism 300, and only the motor shaft 10 that passes the visual detection is marked. The unqualified shaft is directly fed to the first recycling mechanism 550 by the second conveying mechanism 420, thereby avoiding invalid marking (waste of marking materials / time and the need to clean the unqualified products with marks during subsequent recycling) of the unqualified motor shaft 10, and improving the operation efficiency.

[0062] In some embodiments, the motor shaft feeding mechanism 510, the first visual detector 540, the first recycling mechanism 550, the second conveying mechanism 420, the compression assembly conveying mechanism 300, the second visual detector 530, the second recycling mechanism 570, and the marking mechanism 560 are arranged on the rack 100. Figure 2 , the core into the shaft into the magnetic ring machine further comprises a marking mechanism 560 installed on the rack 100, and the marking mechanism 560 is used for marking the motor shaft 10 to realize information management in the production process.

[0063] In some embodiments, the motor shaft feeding mechanism 510, the first visual detector 540, the first recycling mechanism 550, the second conveying mechanism 420, the compression assembly conveying mechanism 300, the second visual detector 530, the second recycling mechanism 570, and the marking mechanism 560 are arranged on the rack 100. Figure 2 and Figure 9The core-into-shaft-into-magnetic-ring machine further comprises a core feeding mechanism 600 installed on the frame 100. The core feeding mechanism 600 comprises a first support 610 installed on the frame 100 and a core support plate 620 installed on the first support 610. The core support plate 620 is provided with at least two core positioning portions 621 spaced apart in sequence along the second direction Y. The core positioning portions 621 realize positioning of the core piece 20, facilitating the first carrying mechanism 410 to grasp without readjusting the grasping angle.

[0064] Specifically, the core feeding mechanism 600 further comprises a first feeding driving member 630 installed on the first support 610 for driving the core support plate 620 to move along the second direction Y. Based on this, the first carrying mechanism 410 grasps the core piece 20 at the same position in the second direction Y each time, reducing the grasping difficulty of the first carrying mechanism 410.

[0065] In some embodiments, in combination with Figure 2 The core-into-shaft-into-magnetic-ring machine further comprises a magnetic ring feeding mechanism 700 for supplying the magnetic ring assembly 30 along the second direction Y. Based on this, when the magnetic ring assembly 30 is supplied along the second direction Y, the first carrying mechanism 410 linearly grasps and linearly transfers to the carrying block 330 along the second direction Y, without additional first direction X transverse movement, greatly shortening the flow time of the magnetic ring assembly 30 and improving the work efficiency.

[0066] In one of the embodiments, in combination with Figure 2 The magnetic ring feeding mechanism 700, the press-fitting conveying mechanism 300 and the core feeding mechanism 600 are distributed along the second direction Y, i.e. the feeding of the core piece 20 and the feeding of the magnetic ring assembly 30 are respectively on the two sides of the press-fitting conveying mechanism 300, avoiding feeding interference and reducing the risk of mechanism collision. The distribution along the second direction Y can maximize the utilization of the linear space of the frame 100, reducing the redundant floor space.

[0067] In some embodiments, in combination with Figure 10 、 Figure 11 and Figure 12The magnetic ring feeding mechanism 700 comprises a second support 710, a feeding turntable 720, a sleeve feeding mechanism 730, a glue coating mechanism 740, a magnetic ring supply mechanism 750 and a magnetic ring output mechanism 760 arranged in sequence around the feeding turntable 720, the feeding turntable 720 is rotatably mounted on the second support 710 in the vertical direction Z, the sleeve feeding mechanism 730 is used for supplying the bushing 31 to the feeding turntable 720, the glue coating mechanism 740 is used for coating the outer periphery of the bushing 31, the magnetic ring supply mechanism 750 is used for supplying the magnetic ring 32 to the feeding turntable 720, so that the magnetic ring 32 is sleeved on the coated bushing 31 to form the magnetic ring assembly 30, and the magnetic ring output mechanism 760 is used for carrying the magnetic ring assembly 30 on the feeding turntable 720 to the first carrying mechanism 410. Based on this, the magnetic ring feeding mechanism 700 can realize automatic gluing of the magnetic ring 32 and the bushing 31, and automatic feeding.

[0068] In one embodiment, the feeding turntable 720 is provided with at least two positioning discs 721, and all the positioning discs 721 are distributed at intervals around the edge of the feeding turntable 720 along the vertical axis. The positioning disc 721 is used for carrying the bushing 31, and the positioning disc 721 rotates with the feeding turntable 720 and is docked with the sleeve feeding mechanism 730, the glue coating mechanism 740, the magnetic ring supply mechanism 750 and the magnetic ring output mechanism 760 respectively.

[0069] Optionally, the number of positioning discs 721 is four, and the four positioning discs 721 are uniformly distributed at intervals around the edge of the feeding turntable 720 along the vertical axis, that is, the central angle of the adjacent two positioning discs 721 is 90°, and the four positioning discs 721 are docked with the magnetic ring supply mechanism 750, the glue coating mechanism 740, the sleeve feeding mechanism 730 and the magnetic ring output mechanism 760 respectively, so that the magnetic ring supply mechanism 750, the glue coating mechanism 740, the sleeve feeding mechanism 730 and the magnetic ring output mechanism 760 can work continuously, and the production efficiency is improved.

[0070] Optionally, the positioning disc 721 is provided with a positioning groove 722, and the positioning groove 722 is used for limiting the sleeving of the bushing 31 and achieving the horizontal positioning of the bushing 31 on the positioning disc 721. The groove bottom of the positioning groove 722 is provided with a first positioning column 723, and the first positioning column 723 is used for sleeving the bushing 31.

[0071] Specifically, the positioning disc 721 has a positioning gap 724, the loading turntable 720 is provided with a positioning driving member 726, the output end of the positioning driving member 726 is connected with a second positioning column 725, and the second positioning column 725 is used for driving the second positioning column 725 to enter or exit the positioning gap 724. When the positioning disc 721 rotates to any one of the magnetic ring supply mechanism 750, the gluing mechanism 740, the sleeve loading mechanism 730 and the magnetic ring output mechanism 760, the positioning driving member 726 drives the second positioning column 725 to enter the positioning gap 724, so that the positioning disc 721 cannot rotate or shake relatively, and stable work of the magnetic ring supply mechanism 750, the gluing mechanism 740, the sleeve loading mechanism 730 and the magnetic ring output mechanism 760 is ensured.

[0072] In one embodiment, the magnetic ring loading mechanism 700 further comprises a second visual detector 771, the second visual detector 771 is installed on the second support 710 and is located beside the gluing mechanism 740, and the second visual detector 771 is used for visual detection of the sleeve 31 corresponding to the gluing mechanism 740.

When the positioning disc 721 rotates to the side of the gluing mechanism 740, the radial driving member 773 drives the rotating driving member 772 to move along the radial direction, so that the rotating connecting block 774 is embedded in the rotating insertion slot 727, the rotating driving member 772 drives the rotating connecting block 774 and the corresponding positioning disc 721 to rotate, and at the same time, the gluing mechanism 740 glues the side wall of the sleeve 31 on the positioning disc 721, and as the sleeve 31 rotates, 360° gluing of the side wall of the sleeve 31 is realized.
