Description

Technical Field

[0001] This invention relates to the field of stator processing technology, and in particular to a production line for post-weld inspection and processing of iron cores for new energy stator drive motors. Background Technology

[0002] The stator, composed of multiple stator laminations welded together, is a core component of the drive motor in new energy vehicles. The quality of stator machining directly affects the performance and lifespan of the drive motor. Stator machining involves various processes, including grinding weld bumps, marking the stator surface, and measuring stator thickness.

[0003] Traditional stator machining processes primarily rely on manual operation, which is time-consuming, labor-intensive, and yields inconsistent quality, while also making the stator susceptible to contamination. To overcome these shortcomings, various machines have emerged on the market for stator machining, such as grinding equipment, marking equipment, and thickness measuring equipment. However, existing equipment still suffers from the following drawbacks:

[0004] (1) The processing equipment for each process is usually independent equipment with low integration, resulting in a large footprint; and the stator needs to be transferred between processing equipment, resulting in low processing efficiency and the risk of contamination during the transfer process.

[0005] (2) Existing grinding equipment can usually only grind one side of the stator. Grinding the other side requires a flipping mechanism, which results in a complex structural design and cumbersome operation procedures.

[0006] (3) Existing coding equipment can only code one side of the stator, and cannot achieve multi-side coding or multi-position coding on the same side of the stator, which makes it impossible to meet the needs of multi-side coding or multi-position coding on the same side.

[0007] (4) There are many stator specifications. The existing processing equipment for each process is not very versatile and is mostly dedicated equipment, which makes it impossible to process stators of multiple specifications and increases the difficulty of integrating each process into one piece of equipment.

Detailed Implementation

[0050] The present invention will now be further described in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0051] Example 1

[0052] like Figure 1 As shown, a new energy stator drive motor core welding post-welding inspection and processing production line includes a workbench 100, a loading mechanism 200 installed at the right end of the workbench 100, a unloading mechanism 300 installed at the left end of the workbench 100, a vision inspection mechanism 400, a grinding mechanism 500, a thickness measuring mechanism 600, a marking mechanism 700, an air shower mechanism 800, an oil spraying mechanism 900, a transition platform 1000, a transport mechanism 1100 disposed between the oil spraying mechanism 900 and the unloading mechanism 300, and a transfer mechanism 1200 installed at the front end of the middle of the workbench 100. The transport mechanism 1100 is used to transport the stator from the transition platform 1000 to the unloading mechanism 300, and the transfer mechanism 1200 is used to transfer the stator. Specifically, the workbench 100 is equipped with a shell to isolate it from the outside environment.

[0053] The visual inspection mechanism 400, grinding mechanism 500, thickness measuring mechanism 600, marking mechanism 700, air shower mechanism 800, and oil spraying mechanism 900 are integrated into the same equipment. The stator is transferred between the various mechanisms through the transfer mechanism 1200. The structure is simple, highly integrated, and occupies a small area, which significantly improves processing efficiency and greatly reduces the risk of pollution.

[0054] like Figure 1 and Figure 3As shown, the feeding mechanism 200 includes a vertical plate 210 disposed above the worktable 100, a support plate 220 slidably mounted on the vertical plate 210, a rodless cylinder 230 mounted on the vertical plate 210, a lifting and weighing assembly 240 disposed below the front end of the vertical plate 210, and a lifting and docking assembly 250 disposed below the rear end of the vertical plate 210. Through holes 211 are provided at both the front and rear ends of the vertical plate 210 to avoid the lifting and weighing assembly 240 and the lifting and docking assembly 250, respectively. A cross hole 221 is provided in the middle of the support plate 220, and the drive end of the rodless cylinder 230 is connected to the left end of the support plate 220. Specifically, the front end of the vertical plate 210 is connected to the worktable 100 via a column, and its rear end extends out of the worktable 100.

[0055] like Figure 3 and Figure 4 As shown, the lifting and weighing assembly 240 includes a lifting plate 241, a lifting cylinder 242, a weighing module 243, and a first cross plate 244. The lifting plate 241 is disposed between the workbench 100 and the longitudinal plate 210, and the first cross plate 244 is connected to the top of the lifting plate 241 through the weighing module 243. The lifting cylinder 242 is mounted on the workbench 100, and its driving end is connected to the bottom end of the lifting plate 241.

[0056] The lifting and weighing component 240 is integrated into the feeding mechanism 200, further improving the integration level. It eliminates the need for secondary handling equipment, allowing for rapid determination of the core weight in a single operation. The weighing module in the control system (not shown in the diagram) automatically calculates the core's stacking factor (a crucial parameter) based on the core weight obtained from the lifting and weighing component 240. Compared to manual sampling and calculation of the stacking factor, this production line achieves full inspection, with the stacking factor calculated for each core and linked to the product's QR code for permanent traceability.

[0057] like Figure 3 and Figure 5As shown, the lifting docking assembly 250 includes a first mounting plate 251, a lifting plate 252, a second cross plate 253, a guide shaft 254, a rotating shaft 255, a transmission shaft 256, a third cross plate 257, a servo motor 258, and a fourth lifting cylinder 259. The first mounting plate 251 is connected to the rear end of the vertical plate 210 via a column. The lifting plate 252 is located below the first mounting plate 251. The second cross plate 253 is located between the vertical plate 210 and the first mounting plate 251. The guide shaft 254 slides through the first mounting plate 251. The top end of the second cross plate 252 is connected to the bottom end of the guide shaft 254, the bottom end of the second cross plate 253 is connected to the top end of the guide shaft 254, and the rotating shaft 255 passes through the middle of the second cross plate 253; the servo motor 258 is installed in the middle of the lifting plate 252, and its output end is connected to the bottom end of the rotating shaft 255 through the transmission shaft 256; the third cross plate 257 is set above the second cross plate 253 and is connected to the top end of the rotating shaft 255; the fourth lifting cylinder 259 is installed on the first mounting plate 251, and its drive end is connected to the second cross plate 253.

[0058] During loading, the fourth lifting cylinder 259 drives the second cross plate 253 to rise until the third cross plate 257 passes through the through hole 211 at the rear end of the longitudinal plate 210 and the cross hole 221 in the middle of the support plate 220 in sequence, and the stator falls on the third cross plate 257; the fourth lifting cylinder 259 drives the second cross plate 253 to fall down, so that the stator falls on the support plate 220; the rodless cylinder 230 drives the support plate 220 to move forward until the support plate 220 reaches the front end of the longitudinal plate 210; the lifting cylinder 242 drives the lifting plate 241 to rise until the first cross plate 244 passes through the through hole 211 at the front end of the longitudinal plate 210 and the cross hole 221 in the middle of the support plate 220 in sequence, and the first cross plate 244 lifts the stator on the support plate 220 for weighing; after weighing is completed, the lifting cylinder 242 drives the lifting plate 241 to fall down, so that the stator falls on the support plate 220.

[0059] like Figure 1 and Figure 6 As shown, the feeding mechanism 300 includes OK roller line 310 and NG roller line 320, which are existing technologies and will not be described in detail here.

[0060] like Figure 1 and Figure 7As shown, the visual inspection mechanism 400 includes a third stand 410 and an inspection platform 420 mounted on the worktable 100, a fine-tuning module 430 mounted on the upper part of the third stand 410, a first light source 440 mounted in the middle of the third stand 410, and a telecentric lens 450 mounted on the slider of the fine-tuning module 430; the inspection platform 420 is located in front of the third stand 410. Specifically, the fine-tuning module 430 can be a handwheel-type linear module. By adjusting the height of the telecentric lens 450 and using visual inspection through the fine-tuning module 430, foreign objects in slots and oil grooves of stators of different specifications can be detected, demonstrating strong versatility.

[0061] like Figure 7 As shown, the testing platform 420 includes a support plate 421, a quartz glass 422, and a backlight plate 423. The support plate 421 is connected to the worktable 100 via a column. The quartz glass 422 is installed in the middle of the support plate 421, and the backlight plate 423 is disposed between the worktable 100 and the support plate 421. Specifically, the backlight plate 423 is connected to the worktable 100 via a side plate.

[0062] like Figure 1 , Figure 8 and Figure 9 As shown, the grinding mechanism 500 includes a first movable module 510 and a first rotary support 520 mounted on the worktable 100, a first upright 530 mounted on the slider of the first movable module 510, a first lifting module 540 mounted on the upper part of the first upright 530, an upper grinding assembly 550 mounted on the slider of the first lifting module 540, a lower grinding assembly 560 mounted on the lower part of the first upright 530, and a clamping assembly 570 mounted on the upper part of the first upright 530; the first rotary support 520 is located in front of the first movable module 510. Specifically, the first movable module 510 can be a linear module; the first lifting module 540 can be a handwheel-type linear module; the first rotary support 520 is existing technology.

[0063] By setting the upper grinding component 550 and the lower grinding component 560 relative to each other, the welding protrusions on the upper and lower surfaces of the stator can be ground without flipping the stator. At the same time, the height of the upper grinding component 550 can be adjusted by the first lifting module 540 to adapt to stators of different heights. The structure is simple, the grinding quality is significantly improved, and it has strong versatility.

[0064] like Figure 8As shown, both the upper grinding assembly 550 and the lower grinding assembly 560 include a grinding cylinder 551, a second mounting plate 552, an elastic floating group 553, a mounting clamp 554, and a grinding group 555. In the upper grinding assembly 550, the grinding cylinder 551 is mounted on the slider of the first lifting module 540, and in the lower grinding assembly 560, the grinding cylinder 551 is mounted on the lower part of the first upright 530. The second mounting plate 552 is mounted on the drive end of the grinding cylinder 551, the mounting clamp 554 is connected to the second mounting plate 552 through the elastic floating group 553, and the grinding group 555 is mounted on the mounting clamp 554.

[0065] By setting the elastic floating group 553, the grinding group 555 can perform elastic floating grinding on the welding protrusions. At the same time, the distance between the grinding group 555 and the stator surface is detected in real time to avoid over-grinding that could cause the stator sheets to explode, thus ensuring the grinding quality.

[0066] like Figure 8 As shown, the elastic floating assembly 553 includes a first floating block 5531, a floating cylinder 5532, a first guide sleeve, a first guide shaft, and a first elastic element. The first floating block 5531 is disposed on the side of the second mounting plate 552 away from the mounting clamp 554. The floating cylinder 5532 is mounted on the second mounting plate 552, and its driving end is connected to the middle of the first floating block 5531. The first guide sleeve is mounted on the second mounting plate 552, and the first guide shaft slides through the first guide sleeve. One end of the first guide shaft is connected to the first floating block 5531, and its other end is connected to the mounting clamp 554. The first elastic element is sleeved on the first guide shaft. One end of the first elastic element abuts against the first guide sleeve, and its other end abuts against the mounting clamp 554. Specifically, there are two first guide sleeves, symmetrically arranged on both sides of the floating cylinder 5532. The first elastic element is a spring. The cooperation between the first guide sleeve and the first guide shaft ensures the stability of the grinding assembly 555 during the grinding process.

[0067] like Figure 8 As shown, the grinding assembly 555 includes an electric spindle 5551 and a grinding head 5552; ​​the electric spindle 5551 is mounted on a mounting clamp 554, and the grinding head 5552 is mounted on the output end of the electric spindle 5551. Specifically, the grinding head 5552 is a tungsten carbide end mill.

[0068] like Figure 8As shown, both the upper grinding assembly 550 and the lower grinding assembly 560 further include a fine-tuning limit group 556. The fine-tuning limit group 556 includes a connecting plate, a slide, a mounting block, a limit plate, and screws. The slide is connected to the mounting clamp 554 via the connecting plate, and the slide is positioned on the side of the mounting clamp 554 furthest from the second mounting plate 552. The limit plate is connected to the slide via the mounting block, and the end of the limit plate furthest from the mounting block has a limit hole corresponding to the grinding assembly 555. The screw threads through the mounting clamp 554 and abut against the slide. Specifically, the slide adopts a cross-roller type, and a micrometer is integrated on the slide to ensure adjustment accuracy; the limit plate is triangular; the grinding head 5552 passes through the limit hole.

[0069] Manually rotating the screw causes the slide table to move the limit plate slightly up and down, allowing the grinding head 5552 to protrude slightly out of the limit hole. During grinding, the limit plate contacts the stator, forming a mechanical hard limit.

[0070] like Figure 8 As shown, the fine-tuning limit group 556 also includes a baffle, which is installed on the side of the limit plate away from the mounting block to prevent the spread of dust during the grinding process.

[0071] like Figure 8 As shown, the clamping assembly 570 includes a clamping cylinder, a clamping plate, and a pad. The clamping cylinder is installed on the upper part of the first upright 530. One end of the clamping plate is connected to the drive end of the clamping cylinder, and the pad is installed on the bottom surface of the other end of the clamping plate to prevent rigid contact between the clamping plate and the stator during the pressing process. Specifically, the clamping plate is L-shaped. The clamping assembly 570 provides flexible positioning of the stator during the grinding process, preventing movement and further ensuring grinding quality.

[0072] like Figure 8 As shown, the polishing mechanism 500 also includes a collection tray 580, which is mounted on the slider of the first moving module 510. The collection tray 580 cooperates with the dust suction head to collect waste generated during the polishing process.

[0073] During grinding, the stator is placed on the first rotating support 520. The first moving module 510 drives the first upright 530 to move closer to the first rotating support 520 until the upper grinding assembly 550 and the lower grinding assembly 560 are aligned with a certain welding protrusion. The pressing assembly 570 presses down to position the stator. The floating cylinder 5532 drives the first floating block 5531 to rise and fall, so that the limiting plate contacts the stator. Finally, the grinding assembly 555 performs grinding. The first rotating support 520 drives the stator to rotate, realizing the grinding of other welding protrusions. The first moving module 510 drives the first upright 530 to move towards the first rotating support 520, which can realize the grinding of stators of different diameters, making it highly versatile.

[0074] It should be emphasized that the grinding mechanism 500 can be set with grinding points at different locations and with different diameters, resulting in excellent consistency. At the same time, the grinding depth can be set as needed to ensure consistency, thereby ensuring the dynamic balance performance of the entire iron core during rotation.

[0075] like Figure 1 , Figure 10 and Figure 11 As shown, the thickness measuring mechanism 600 includes a second moving module 610 and a second rotating support 620 mounted on the worktable 100, a bracket 630 mounted on the slider of the second moving module 610, a second lifting module 640 mounted on the top of the bracket 630, an upper measuring component 650 mounted on the slider of the second lifting module 640, and a lower measuring component 660 mounted on the front side of the bracket 630; the second rotating support 620 is located in front of the second moving module 610. Specifically, the second moving module 610 and the second lifting module 640 are linear modules.

[0076] By driving the bracket 630 to move towards the second rotating support 620 via the second moving module 610, thickness measurement at different points on stators of different diameters can be achieved, making it highly versatile.

[0077] like Figure 10 and Figure 12 As shown, both the upper measuring assembly 650 and the lower measuring assembly 660 include a measuring cylinder 651, a third mounting plate 652, a measuring head 653, a second floating block 654, a second guide sleeve, a second guide shaft, a limiting angle plate, and a second elastic element. In the upper measuring assembly 650, the measuring cylinder 651 is mounted on the slider of the second lifting module 640. In the lower measuring assembly 660, the measuring cylinder 651 is mounted on the front side of the bracket 630. The measuring head 653 is mounted on the drive end of the measuring cylinder 651 via the third mounting plate 652. The second floating block 654 is located on the side of the third mounting plate 652 near the stator. A clearance hole is provided in the middle of the two floating blocks 654 for the measuring head 653 to pass through. The second guide sleeve is mounted on the third mounting plate 652. The second guide shaft slides through the second guide sleeve, and its end near the stator is connected to the second floating block 654. The second elastic element is sleeved on the second guide shaft. One end of the second elastic element abuts against the second floating block 654, and its other end abuts against the second guide sleeve. One end of the limiting angle plate is connected to the third mounting plate 652, and its other end extends between the third mounting plate 652 and the second floating block 654. The other end of the limiting angle plate has a notch for the measuring head 653 to pass through. Specifically, there are two second guide sleeves, symmetrically arranged on both sides of the measuring head 653. The limiting angle plate is designed to limit the maximum displacement of the second floating block 654, preventing the measuring head 653 from excessively contacting the stator.

[0078] During measurement, the second moving module 610 drives the bracket 630 to move towards the second rotating support 620 until the upper measuring component 650 and the lower measuring component 660 are directly facing the stator on the second rotating support 620. The measuring cylinder 651 drives the third mounting plate 652 to move towards the second rotating support 620. The second floating block 654 first contacts the stator. As the measuring cylinder 651 continues to drive the third mounting plate 652, it forces the second floating block 654 to move towards the third mounting plate 652, compressing the second elastic element until the measuring head 653 contacts the stator for measurement. To ensure the reliability of the measurement results, the second rotating support 620 drives the stator to rotate, enabling multi-point measurement on the stator. A plane (such as the bottom surface of the stator) is defined by these multiple points to ensure flatness. Then, the distance between a point on the top surface of the stator and the plane is calculated.

[0079] like Figure 1 and Figure 13 As shown, the coding mechanism 700 includes a second upright 710, an upright plate 720, and a lifting and rotating platform 730 mounted on the workbench 100; an upper coding assembly 740 mounted on the upper part of the second upright 710; an upper scanning assembly 750 mounted in the middle of the second upright 710; a gripping and flipping assembly 760 mounted on the lower part of the second upright 710; a side scanning assembly 770 mounted on the upper part of the upright plate 720; a side coding assembly 780 mounted in the middle of the upright plate 720; and a light source assembly 790 mounted on the lower part of the upright plate 720. The upright plate 720 is located next to the second upright 710, and the lifting and rotating platform 730 is located in front of the second upright 710.

[0080] The combination of upper coding component 740, side coding component 780, upper scanning component 750, side scanning component 770, and gripping and flipping component 760 integrates coding and scanning functions, achieving high integration and enabling multi-sided and same-sided multi-position coding. Furthermore, the lifting and rotating platform 730 allows for adjustment of the distance between the platform and the upper coding component 740 according to different stator specifications, ensuring stable coding results and strong versatility.

[0081] like Figure 13 As shown, the lifting and rotating platform 730 includes a fourth mounting plate 731, a rotating table 732, and a first lifting assembly.

The rotating table 732 is mounted on the fourth mounting plate 731 and is used to drive the stator to rotate. Specifically, the first lifting assembly can be an electric cylinder; the rotating table 732 is existing technology.

[0082] During coding, for stators of different sizes, the first lifting group drives the fourth mounting plate 731 to rise and fall, adjusting the distance between the rotary table 732 and the upper coding component 740 to ensure coding effect. The rotary table 732 drives the stator to rotate, enabling coding and scanning at different positions on the same side of the stator.

[0083] like Figure 13 As shown, the lifting and rotating platform 730 also includes a guide assembly to ensure the stable lifting and lowering of the fourth mounting plate 731. The guide assembly includes a third guide sleeve and a third guide shaft; the third guide sleeve is mounted on the worktable 100; the third guide shaft slides through the third guide sleeve, and its top end is connected to the fourth mounting plate 731. Specifically, there are four guide assemblies, respectively located at the four corners of the fourth mounting plate 731.

[0084] like Figure 13 As shown, the upper barcode scanning assembly 750 includes an advance / reverse cylinder, an upper connecting plate, and an upper barcode scanner; the advance / reverse cylinder is installed in the middle of the second stand 710; one end of the upper connecting plate is connected to the drive end of the advance / reverse cylinder, and the other end passes through the upper through hole in the middle of the second stand 710 and is connected to the upper barcode scanner.

[0085] During scanning, the forward and backward cylinder drives the upper barcode scanner to move forward and backward through the upper connecting plate, so as to scan the top and bottom surfaces of the stator while avoiding the coding of the upper coding component 740.

[0086] like Figure 13 As shown, the gripping and flipping assembly 760 includes a second sliding plate 761, a second lifting group 762, a flipping motor 763, and a gripping group.

The second lifting group 762 is mounted on the bottom end of the second upright 710, and its drive end is connected to the second sliding plate 761. The flipping motor 763 is mounted on the middle part of the second sliding plate 761, and its output end is connected to the gripping group. Specifically, the lower part of the second upright 710 has a lower through hole for the flipping motor 763 to lift and lower.

[0087] During operation, the gripping group holds the stator on the rotary table 732, the second lifting group 762 drives the second sliding plate 761 to rise, so that the stator is raised to a certain height; then the flipping motor 763 drives the gripping group to flip, so that the bottom surface of the stator faces upward; finally, the second lifting group 762 drives the second sliding plate 761 to descend and reset, so that the stator falls back onto the rotary table 732.

[0088] like Figure 13 As shown, the gripping assembly includes a gripping cylinder, grippers, and a gripping block. The gripping cylinder is installed at the output end of the flipping motor 763, the grippers are installed at the drive end of the gripping cylinder, and the gripping block is installed on the inner side of the grippers. Specifically, the side of the gripping block near the stator is V-shaped to ensure stable gripping of the stator.

[0090] During scanning, the fifth lifting cylinder drives the side scanner to rise and fall through the side connecting plate, so as to achieve scanning on the side of the stator while avoiding the coding of the side coding component 780.

[0091] like Figure 13 As shown, the light source assembly 790 includes a cross arm and a second light source; one end of the cross arm is connected to the lower part of the vertical plate 720, and the other end is connected to the second light source. Specifically, the second light source corresponds to the stator on the rotary table 732.

[0092] During the coding process, the transfer mechanism 1200 transfers the stator to the rotary table 732. The upper coding component 740, the side coding component 780, and the rotary table 732 work together to perform multi-position coding on the top and sides of the stator. Then, the clamping and flipping component 760 flips the stator, and the upper coding component 740 and the rotary table 732 work together to perform multi-position coding on the bottom surface of the stator. Next, the upper scanning component 750 and the side scanning component 770 scan the codes to achieve QR code recognition and grade assessment. Finally, the transfer mechanism 1200 transfers the stator from the rotary table 732 to the next workstation. It should be noted that the scanning process can be performed after all codes are printed, or after each code is printed. After scanning, the QR code information is uploaded to the MES system for subsequent tracking.

Specifically, there are two air ducts, respectively located at both ends of the first connecting block. One air duct is used for cleaning the inner wall of the stator, and the other air duct is used for cleaning the outer wall of the stator.

[0095] During air shower cleaning, the first lifting cylinder 840 drives the first upper sealing cover 850 to descend until the first upper sealing cover 850 and the first lower sealing cover 830 make sealing contact; the first rotating platform 820 drives the stator to rotate, and at the same time the first lifting component 870 drives the air shower component 860 to rise and fall, so as to achieve no dead corners and uniform air shower on the inner and outer walls of the stator, resulting in a good cleaning effect.
