[0042] Please refer to Figure 1 and Figure 2 The iron core into shaft into magnetic ring machine provided by the embodiment of the 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 perpendicular to each other.

[0043] In combination with 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 column 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, and 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 in the up-down direction, and the motor shaft 10 is clamped in the up-down direction.

[0044] In combination with Figure 7 and Figure 8The press-fitting conveying mechanism 300 comprises a conveying driving member 310, a conveying guide member 320 and a carrying block 330. The conveying guide member 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 member 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 member 320 and 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 in the vertical direction Z overlaps the output end of the jacking driving member 230.

[0045] Referring back to Figure 1 and Figure 2 , the first and second carrying mechanisms 410 and 420 are respectively located at the two ends of the conveying guide member 320 in the first direction X. The first carrying mechanism 410 is used to carry the magnetic ring assembly 30 and the core member 20 to the carrying block 330, and the second carrying mechanism 420 is used to carry the motor shaft 10 to the carrying block 330.

[0046] Specifically, referring back to Figure 3 , first, the carrying block 330 is driven by the conveying driving member 310 to move along the first direction X to the second carrying mechanism 420, the second carrying mechanism 420 carries the motor shaft 10 to the carrying block 330, and the carrying 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 jacking driving member 230 clamp the motor shaft 10 up and down, the clamping driving member 240 is used to clamp the motor shaft 10 horizontally, the output end of the jacking driving member 230 is lowered, and the motor shaft 10 is clamped and fixed on the press-fitting device 200. Third, the carrying block 330 is driven by the conveying driving member 310 to move along the first direction X to the first carrying 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 jacking driving member 230 is raised to abut against the bottom end of the motor shaft 10 through the first hollow part 214 of the press-fitting bottom plate 211, the second hollow part 321 of the conveying guide member 320 and the third hollow part 331 of the carrying block 330, and clamps the motor shaft 10 up and down with the press-fitting head 250, and is lowered synchronously to press the motor shaft 10 into the core member 20 below, realizing the assembly of the motor shaft 10 and the core member 20. Fifth, similar to the core assembly, the carrying block 330 moves the magnetic ring assembly 30 to directly below the press-fitting head 250, the output end of the jacking driving member 230 and the press-fitting head 250 clamp the motor shaft 10 up and down, and are lowered synchronously to press the motor shaft 10 into the magnetic ring assembly 30, realizing the assembly of the motor shaft 10 and the magnetic ring assembly 30.

[0047] Based on this, the iron core into the shaft into the magnetic ring machine realizes automatic assembly of the motor shaft 10, the iron core part 20 and the magnetic ring assembly 30, without the need for separate assembly or manual assembly in different equipment, reducing the transfer time and improving the production efficiency.

[0048] In some embodiments, in combination Figure 4 The jacking drive 230 plays a role of lifting the motor shaft 10 in the press-fitting process, prevents the motor shaft 10 from shaking, and guarantees the coaxial press-fitting of the motor shaft 10, the magnetic ring assembly 30 and the iron core part 20. The output end of the jacking drive 230 is connected with a first jack rod 231, and the end of the first jack rod 231 is provided with a first positioning cone 232 for positioning the end part of the embedded motor shaft 10. The vertex of the first positioning cone 232 can be embedded into the end groove of the motor shaft 10 of different specifications, and the contact with the end of the motor shaft 10 is increased through the conical side surface of the first positioning cone 232, further limiting the displacement of the motor shaft 10 in the horizontal plane.

[0049] In some embodiments, in combination Figure 4 The jacking drive 230 is connected with a hollow first guide cylinder 233, the top end of the first guide cylinder 233 is installed on the press-fitting bottom plate 211, and the first guide cylinder 233 and the press-fitting head 250 are coaxially arranged in the vertical direction Z. The first guide cylinder 233 is used for guiding the first jack rod 231 to pass through the first hollow part 214 in the vertical direction Z. The first guide cylinder 233 directly limits the first jack rod 231 to move only in the vertical direction Z, completely eliminating the horizontal deviation or inclination of the first jack rod 231 caused by uneven jacking force, too large length-diameter ratio, easy bending or slight deviation of the jacking drive 230.

[0050] In some embodiments, in combination Figure 5 and Figure 6 The press-fitting head 250 includes a press-fitting cylinder body 251 and a second jack rod 252. The press-fitting cylinder body 251 is installed on the output end of the downward pressing drive 220, and the second jack rod 252 is installed on the press-fitting cylinder body 251. The end of the second jack rod 252 is provided with a second positioning cone 253 for positioning the end part of the embedded 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 of the motor shaft 10 is increased through the conical 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.

[0051] In one of the embodiments, the press-fitting cylinder body 251 has a positioning sleeve hole 254 for movably sleeving the end outer periphery of the motor shaft 10, which 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 press-fitting head 250.

[0052] In one of the embodiments, the second top rod 252 is installed in the positioning sleeve hole 254, and 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 top rod 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 top rod 252.

[0053] In one of the embodiments, in combination with Figure 5 and Figure 6 , the press-fitting head 250 further comprises a downward pressing elastic member 255, one end of the downward pressing elastic member 255 is installed at the bottom of the hole of the positioning sleeve hole 254, and the other end of the downward pressing elastic member 255 is installed at the top of the second top rod 252. When the end of the motor shaft 10 contacts the second top rod 252, the downward pressing elastic member 255 will be compressed with the slight retreat of the second top rod 252, and the impact force during the butt joint will be automatically offset by the elastic force.

[0054] In addition, on the one hand, if the motor shaft 10 is unevenly stressed during the press-fitting, the downward pressing elastic member 255 can be slightly compressed on one side and kept original length on the other side, driving the second top 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 pressing elastic member 255 can be transmitted to the motor shaft 10 through the second top rod 252, and in combination with the radial constraint of the positioning sleeve hole 254, the motor shaft 10 is slowly corrected to the coaxial position, avoiding the bias problem caused by the error accumulation.

[0055] In one of the embodiments, in combination with Figure 6 , the output end of the clamping driving member 240 is connected with a clamping block 241, the clamping driving member 240 drives the clamping block 241 to move in the radial direction of the press-fitting head 250, so as to realize the circumferential limiting of the motor shaft 10, which 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.

[0056] In one of the embodiments, the clamping block 241 has a clamping shaft notch 242, and the inner walls of the opposite sides 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.

[0057] In one of the embodiments, in combination with Figure 5 and Figure 6A clamping and positioning block 260 is installed at the bottom of the press-fit head 250. The clamping and positioning block 260 has a first receiving through hole 261 for accommodating the motor shaft 10, and a second receiving through hole 262. One end of the second receiving through hole 262 is connected to the first receiving through hole 261, and the other end of the second receiving through hole 262 passes through the outer side wall of the clamping and positioning block 260 radially along the press-fit head 250. The second receiving through hole 262 is used to allow the clamping block 241 to move radially. The first receiving through hole 261 restricts the circumferential position of the motor shaft 10, further preventing the axial displacement of the motor shaft 10, and ensuring that the axial movement of the motor shaft 10 will not be caused by the clamping block 241 clamping the motor shaft 10. The second receiving through hole 262 provides rigid guidance for the radial movement of the clamping block 241, improving the movement stability of the clamping block 241. The clamping block 241 is completely hidden within the second receiving through hole 262, preventing the clamping block 241 from being disturbed by external interference.

[0058] In one embodiment, combined with Figure 6 There are two clamping drive units 240. The two clamping drive units 240 are arranged radially opposite each other along the press head 250 so that the output ends of the two clamping drive units 240 come together to form a symmetrical clamping force and avoid the motor shaft 10 from being deflected by force.

[0059] In one embodiment, combined with Figure 6 The side of the pressing head 250 has a mounting plane 256, and the clamping drive component 240 is fitted onto the mounting plane 256, which provides a mounting reference for the clamping drive component 240. The large plane contact area improves the installation stability of the clamping drive component 240.

[0060] In one embodiment, the pressing head 250 is connected to a positioning rod 270, which extends downward in the vertical direction Z and protrudes below the pressing head 250. The positioning rod 270 is used for positioning and insertion into the iron core component 20, preventing the iron core from rotating during the pressing process. Especially when multiple iron core components 20 are assembled on one motor shaft 10, or when iron cores and magnetic ring assemblies 30 are pressed continuously, the positioning rod 270 maintains circumferential positioning of the first iron core component 20 between multiple pressing operations, avoiding deviations in the iron core installation angle.

[0061] In one of the embodiments, the press-fitting device 200 further comprises a first photoelectric sensor 281 mounted on the press-fitting column 213, which detects the carrier block 330 in the second direction Y, and the detection height of the first photoelectric sensor 281 is 5-50 mm higher than the top surface of the carrier block 330. The first photoelectric sensor 281 is used to detect whether the carrier block 330 carries the component to be assembled, so as to confirm whether the jacking drive 230 and the pressing drive 220 are started. If the detection height is less than 5 mm, the accumulation of sundries such as metal scraps and dust may trigger false detection.

[0062] In one of the embodiments, the press-fitting device 200 further comprises a second photoelectric sensor 282 mounted on the press-fitting column 213, which detects whether the press-fitting head 250 is lowered to a preset height in the second direction Y. When the press-fitting head 250 is lowered to the preset height, the second sensor detects the press-fitting head 250 and immediately sends a signal to the controller to trigger the press-fitting head 250 to stop lowering or switch actions (such as from "fast descent" to "slow press-fitting"), so as to avoid damage to the component caused by excessive lowering of the press-fitting head 250, and greatly reduce the defective rate and equipment maintenance cost.

[0063] In one of the embodiments, in combination with Figure 2 , the press-fitting device 200 further comprises a code reader 283 mounted on the press-fitting column 213, which is used to scan the motor shaft 10 located on the carrier block 330. After the code reader 283 scans the code of the motor shaft 10, on one hand, the press-fitting device 200 can select appropriate press-fitting force and press-fitting depth; on the other hand, it can assist in realizing automatic statistics of production data.

[0064] In one of the embodiments, in combination with Figure 4 , the 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 change in the press-fitting process in real time, and feed back the data to the controller, so as to ensure that the press-fitting force is always within the preset process range, and to ensure the consistency of assembly quality. In this embodiment, the pressure sensor 284 records the force-displacement curve throughout the process, and binds and stores the identity information of the motor shaft 10 (obtained through the code reader 283). The production management personnel can analyze the force value curve of a batch to optimize the process parameters (such as adjusting the press-fitting speed and correcting the target force value), for example, if the average press-fitting force of a batch of motor shafts 10 is found to be too high, it can be traced back to the large shaft diameter tolerance, and then feedback to the upstream processing link for adjustment.

[0065] In some embodiments, in combination with Figure 2 and Figure 4The number of the 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.

[0066] In one embodiment, 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 plurality of 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.

[0067] Specifically, the number of the 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 the pressing driving members 220, the lifting driving members 230, the clamping driving members 240, and the press-fitting heads 250 is two. The first conveying mechanism 410 and the second conveying mechanism 420 can simultaneously convey two components, i.e., the first conveying mechanism 410 simultaneously grasps two core pieces 20 and places them on the carrying blocks 330 of the two press-fitting conveying mechanisms, simultaneously grasps 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 grasps 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, the two lifting driving members 230, and the two clamping driving members 240 move synchronously, which can make the power output and mechanical stress of the two stations more balanced and avoid the problem of uneven wear of the press-fitting device 200 caused by long-term bearing of larger load by a single station.

[0068] In some embodiments, in combination with Figure 2 , Figure 7 and Figure 8 , the carrying block 330 includes 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 to place 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 spaced apart along the first direction X. The first conveying block 340 and the second conveying block 350 both have a third hollow part 331.

[0069] Therefore, the first conveying mechanism 410, the press-fitting device 200, and the second conveying mechanism 420 are spaced apart along the first direction X, the first conveying block 340 is used to be docked with the first conveying mechanism 410, and the second conveying block 350 is used to be docked 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 group 341 avoids the rotation deviation of the core piece 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.

[0070] Specifically, the core positioning pin group 341 is two cylindrical pins distributed in a diagonal manner.

[0071] 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 is moved along the first direction X close to the press-fitting head 250, and the core piece 20 is assembled to the motor shaft 10 in sequence, and finally the magnetic ring assembly 30 is assembled to the motor shaft 10.

[0072] In one of the embodiments, all the core positioning pin groups 341 are arranged to be deflected around the vertical direction Z in a preset angle in sequence, so that the plurality of core pieces 20 are staggered and press-fitted to the same motor shaft 10 in a preset angle.

[0073] In one of the embodiments, the second conveying block 350 is used to place the motor shaft 10, and the motor shaft 10 is separately fed with the core piece 20.

[0074] In some embodiments, the conveying drive 310 includes a first drive 311 and a second drive 312, the first drive 311 is used to drive the first conveying block 340, and the second drive 312 is used to drive 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.

[0075] In one of the embodiments, in combination with Figure 7 , the first drive 311 and the second drive 312 are respectively located on the opposite sides of the conveying guide 320 in the second direction Y. On the one hand, the first drive 311 and the second drive 312 are arranged on the opposite sides of the conveying guide 320, and the force generated during driving can be offset along the second direction Y, so that the conveying guide 320 is balanced as a whole without additional eccentric moment; on the other hand, the design of being arranged on the opposite sides can disperse the installation space of the first drive 311 and the second drive 312 to the left and right sides of the conveying guide 320, and fully utilize the space in the second direction Y.

[0076] In one of the embodiments, in combination with Figure 7, the conveying guide 320 is a sliding rail, the conveying driver 310 drives the carrier block 330 to slide in the first direction X, the conveying guide 320 is stationary, the second hollow part 321 is stationary and overlaps the first hollow part 214 vertically. It can be understood that in other embodiments, the conveying guide 320 is a conveying belt, the conveying driver 310 drives the conveying belt to rotate, thereby driving the carrier block 330 to move in the first direction X, the second hollow part 321 of the conveying guide 320 and the third hollow part 331 of the carrier block 330 overlap vertically and move together in the first direction X to overlap the first hollow part 214 vertically, thereby allowing the output end of the jacking driver 230 to pass through.

[0077] In some embodiments, in combination with Figure 1 and Figure 2 , the first conveying mechanism 410 is a first robot, which improves the coverage of the working range and facilitates flexible grabbing of the core member 20 and the magnetic ring assembly 30. The second conveying mechanism 420 is a second robot, which improves the coverage of the working range and facilitates flexible grabbing of the motor shaft 10.

[0078] In some embodiments, in combination with Figure 1 and Figure 2 , the core-into-shaft-into-magnetic-ring machine includes a shaft feeding mechanism 510 mounted on the rack 100, which realizes automatic feeding of the motor shaft 10 and improves production efficiency.

[0079] In one of the embodiments, the shaft feeding mechanism 510 is used to transport the shaft insertion plate 520 in the second direction Y, the shaft insertion plate 520 is inserted with a plurality of motor shafts 10, realizing batch centralized feeding, greatly improving the feeding efficiency, and directly solving the pain points of low single feeding efficiency and easy bumping. The shaft feeding mechanism 510 is located on one side of the press-fit conveying mechanism 300 in the second direction Y, fully utilizing the space in the second direction Y, reducing the size of the equipment in the first direction X, and compressing the overall land occupation of the equipment; at the same time, separating the "feeding area" from the "main assembly area" to avoid the overlap of the feeding module and the press-fit conveying mechanism 300 in space.

[0080] Optionally, the core-into-shaft-into-magnetic-ring machine includes a shaft material vehicle 530, which is connected to the shaft feeding mechanism 510 on the side away from the press-fit conveying mechanism 300, avoiding interference with the press-fit, and being away from the press-fit working area, which is beneficial to the safety of feeding.

[0081] In some embodiments, in combination with Figure 1 and Figure 2The shaft loading mechanism 510, the second conveying mechanism 420, and the pressing and conveying mechanism 300 are distributed sequentially and at intervals along the second direction Y. The second conveying mechanism 420 directly grabs the motor shaft 10 at the output end of the shaft loading mechanism 510 without adjusting the grabbing direction. It moves along the second direction Y from the shaft loading mechanism 510 to the pressing and conveying mechanism 300. After grabbing, it only needs to move a short distance to place the motor shaft 10 onto the carrier block 330 of the pressing and conveying mechanism 300, thus improving work efficiency.

[0082] In one embodiment, the iron core insertion shaft and magnetic ring insertion machine also includes a first visual detector 540 mounted on the frame 100. The first visual detector 540 is located between the shaft loading mechanism 510 and the pressing and conveying mechanism 300, and is used to detect the appearance quality of the motor shaft 10. Based on this, the first visual detector 540 intercepts motor shafts 10 with appearance defects in advance, preventing defective products from flowing into subsequent processes and ensuring assembly quality. Furthermore, the first visual detector 540 replaces manual visual inspection, improving inspection efficiency and consistency, and adapting to the automated cycle time. The first visual detector 540 is located between the shaft loading mechanism 510 and the pressing and conveying mechanism 300. After the second conveying mechanism 420 picks up the motor shaft 10 from the shaft loading mechanism 510, it needs to move to the pressing and conveying mechanism 300. This movement path passes through the detection area of ​​the first visual detector 540, and the first visual detector 540 simultaneously completes imaging and analysis, improving inspection efficiency.

[0083] In one embodiment, combined Figure 2 The iron core insertion shaft and magnetic ring insertion machine also includes a first recycling mechanism 550 installed on the frame 100. The movement trajectory of the second conveying mechanism 420 passes through the first recycling mechanism 550, and the detection range of the first vision detector 540 covers the area above the first recycling mechanism 550. Based on this, after the second conveying mechanism 420 grabs the motor shaft 10 from the shaft feeding mechanism 510, it needs to move to the pressing and conveying mechanism 300, which inevitably passes through the first recycling mechanism 550. At this time, the motor shaft 10 is detected by the first vision detector 540. If it passes the test, it continues to move to the pressing and conveying mechanism 300; if it fails the test, it is placed in the first recycling mechanism 550 and returns to grab the next motor shaft 10, thus improving the efficiency of feeding and detection.

[0084] In one embodiment, combined 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 carrying 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 carrying mechanism 420 needs to stay in the second direction Y twice, 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 carrying mechanism 420 only needs to stay between the first visual detector 540 and the first recycling mechanism 550 once. If the detection is qualified, the second carrying 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.

[0085] In one of the embodiments, the motor shaft feeding mechanism 510, the first visual detector 540, the first recycling mechanism 550, the second carrying mechanism 420, the second visual detector 530, the second recycling mechanism 570, the compression assembly mechanism 300, the marking mechanism 560, and the unloading mechanism 800 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 the informatization management of the production process.

[0086] 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.

[0087] 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 carrying mechanism 420, thereby avoiding the invalid marking (waste of marking materials / time, and the unqualified products with marks need to be cleaned during subsequent recycling) of the unqualified motor shaft 10, and improving the operation efficiency.

[0088] In some embodiments, the motor shaft feeding mechanism 510, the first visual detector 540, the first recycling mechanism 550, the second carrying mechanism 420, the second visual detector 530, the second recycling mechanism 570, the compression assembly mechanism 300, the marking mechanism 560, and the unloading mechanism 800 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 the informatization management of the production process.

[0089] In some embodiments, the motor shaft feeding mechanism 510, the first visual detector 540, the first recycling mechanism 550, the second carrying mechanism 420, the second visual detector 530, the second recycling mechanism 570, the compression assembly mechanism 300, the marking mechanism 560, and the unloading mechanism 800 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] Optionally, the number of positioning discs 721 is four, and the four positioning discs 721 are evenly 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.

[0096] 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 to realize 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.

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 notch 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.

[0098] 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 visually detecting the sleeve 31 corresponding to the gluing mechanism 740.
