Description

Technical Field

[0001] The present invention relates to the technical field of automated equipment, and particularly to a segmented stator pre-rounding machine and its operation method. Background Art

[0002] An electric motor generally includes a stator and a rotor. Taking an AC motor as an example, the rotor is placed inside the stator, and an alternating magnetic field is induced by passing alternating current into the stator to drive the rotor to rotate. Traditional stators are of two types: squirrel-cage type and wound-rotor type. Now, due to the high degree of automation in production, the structural form of the stator has also changed greatly. There is a new type of combined stator, which disassembles the stator into individual stator blocks. Each stator block is independently wound as an excitation winding, and then several stator blocks are fitted into a circle and nested into an annular forming hoop, thereby assembling the stator of the motor.

[0003] Currently, when processing such a stator, first, a winding machine is used to wind each stator block. Then, workers manually fit the stator blocks into a circle. Next, a matching forming hoop is fetched, and the forming hoop is forcibly pressed onto the stator block fitting circle from top to bottom by a machine, so as to tightly fit the stator blocks inside the forming hoop. However, this method first affects the processing accuracy, and it is difficult to position when forming a circle. Secondly, it is easy to damage the stator blocks. Thirdly, there is too much manual operation, the labor time is long, and high proficiency of technicians is required. All of these increase the production cost of the enterprise and affect the product quality.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It can be understood that the specific embodiments described herein are only for explaining the present invention, rather than limiting the present invention. In addition, it should be noted that, for the sake of description, only the parts related to the present invention rather than all the structures are shown in the drawings. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Reference to "embodiment" in this text means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0036] Please refer to Figures 1 to 14 , the segmented stator pre-rounding machine of the present invention includes a frame 100, a core turning and accommodating assembly 200 for turning and accommodating the core, a core feeding assembly 300 for transferring the core into the core turning and accommodating assembly 200, a core pre-rounding assembly 500 for limiting and assembling a plurality of cores into a circular stator, a core inserting assembly 600 for inserting the core in the core turning and accommodating assembly 200 into the core pre-rounding assembly 500, a stator fastening assembly 700 for performing a fastening action on the formed stator, and a stator coding and detecting assembly 800 for coding and detecting the pre-rounded stator;

[0037] This segmented stator pre-rounding machine is mainly used to assemble single segmented cores into a circular stator;

[0038] The core feeding assembly 300 and the core turning and accommodating assembly 200 are both arranged on the frame 100, the core pre-rounding assembly 500 is arranged on one side of the core turning and accommodating assembly 200, the core inserting assembly 600 is arranged above the core pre-rounding assembly 500, the stator fastening assembly 700 is installed outside the core pre-rounding assembly 500, and the stator coding and detecting assembly 800 is arranged on the frame 100.

[0039] Among them, the frame 100 plays a role of fixing and supporting each structure in the present invention. At the same time, the iron core feeding component 300 can timely transfer the iron core to be formed into a circle into the iron core flipping and accommodating component 200. The iron core flipping and accommodating component 200 adsorbs the iron core and rotates it by a certain angle, so that the iron core in the iron core flipping and accommodating component 200 is adapted to the iron core pre-forming circular component 500. Furthermore, the iron core flipping and accommodating component 200 and the iron core inserting component 600 cooperate with each other to insert the iron core in the iron core flipping and accommodating component 200 into the iron core pre-forming circular component 500. When the iron core is pre-formed into a stator in the iron core pre-forming circular component 500, the pre-formed stator is transferred into the stator fastening component 700, so that the stator fastening component 700 fastens and fixes the outer diameter of the stator. Then, the stator fastened by the stator fastening component 700 enters the stator coding and detecting component 800. The stator coding and detecting component 800 codes and scans the stator, and detects whether the lead arrangement in the stator is uniform, thus completing the pre-forming circular action of the split stator of the whole present invention.

[0040] Of course, a defective product accommodating station 960 can also be fixedly arranged on the frame 100 of the present invention. The defective product accommodating station 960 is used to accommodate the defective stator after being detected by the stator coding and detecting component 800.

[0041] In this embodiment, the iron core flipping and accommodating component 200 includes an iron core accommodating slide plate 210, an iron core accommodating fixing plate 220, an iron core placing member 230, an iron core flipping driving motor 240, an iron core flipping shaft, an iron core limiting air cylinder 260, an iron core limiting plate 270, a slide plate driving air cylinder 280 and an iron core blanking block 290. The iron core accommodating slide plate 210 is installed on the frame 100, the iron core accommodating fixing plate 220 is installed on the iron core accommodating slide plate 210, the iron core flipping driving motor 240 is installed on the iron core accommodating fixing plate 220, and the output end of the iron core flipping driving motor 240 is connected to the iron core flipping shaft. The iron core placing member 230 is installed on the iron core flipping shaft. The iron core limiting air cylinder 260 is fixedly connected to the side wall of the iron core accommodating fixing plate 220, and the output end of the iron core limiting air cylinder 260 is connected to the iron core limiting plate 270. The slide plate driving air cylinder 280 is installed on the side wall of the iron core accommodating slide plate 210, and the output end of the slide plate driving air cylinder 280 is connected to the iron core accommodating fixing plate 220. The iron core blanking block 290 is installed on the side wall of the iron core accommodating slide plate 210, and the slide plate driving air cylinder 280 drives the iron core limiting plate 270 to pass through the iron core blanking block 290.

[0042] Among them, the iron core transferred to the iron core flipping and accommodating assembly 200 by the iron core feeding assembly 300 is first placed on the iron core placing member 230. The iron core placing member 230 can be magnetic to adsorb and fix the iron core. At this time, the iron core flipping drive motor 240 enters the working state. The iron core flipping drive motor 240 drives the iron core flipping rotating shaft 250 to rotate, so that the iron core placing member 230 rotates towards the iron core limiting plate 270, and then the iron core in the iron core placing member 230 changes its orientation and faces the iron core limiting plate 270. At this time, the iron core limiting cylinder 260 enters the working state, so that the iron core limiting cylinder 260 drives the iron core limiting plate 270 to approach the flipped iron core placing member 230, and then the iron core is fixed under the mutual cooperation of the iron core limiting plate 270 and the iron core placing member 230. Further, the slide plate drive cylinder 280 enters the working state, driving the iron core accommodating fixed plate 220 to move on the iron core accommodating slide plate 210, so that the iron core limiting plate 270 passes through the iron core blanking block 290. Under the action of the iron core inserting assembly 600, the iron core in the iron core limiting plate 270 passes through the iron core blanking block 290 in sequence and enters the iron core pre-forming circular assembly 500.

[0043] In this embodiment, a plurality of equally spaced iron core fixing through holes 273 for ensuring the vertical movement of the iron core are provided on the iron core limiting plate 270. A buffer member 271 and a buffer spring 272 are arranged in the iron core fixing through hole 273. The buffer member 271 is slidably connected to the iron core limiting plate 270, and the buffer spring 272 is sleeved on the buffer member 271.

[0044] Among them, the iron core fixing through hole 273 is used to accommodate the iron core to be inserted. And when the iron core flipping and accommodating assembly 200 flips the iron core and inserts it into the iron core fixing through hole 273, the iron core abuts against the buffer member 271. At the same time, the buffer member 271 and the buffer spring 272 sleeved on the buffer member 271 interact and abut against the iron core, which can prevent the iron core from displacing only in the vertical direction, thereby improving the insertion convenience of the iron core inserting assembly 600.

[0045] In this embodiment, the iron core loading assembly 300 includes a loading bracket 301, a conveyor belt device 302 for conveying the fixture tray, a longitudinal loading drive device 303, a transverse loading slide 304, a vertical loading drive cylinder 305, a vertical loading drive plate 306, a first drive cylinder 307, a first staggered clamping plate 308, a second drive cylinder 309, and a second staggered clamping plate 310. The loading bracket 301 is installed on the frame 100. The conveyor belt device 302 is installed on one side of the loading bracket 301. The longitudinal loading drive device 303 is installed at the end of the loading bracket 301. The transverse loading slide 304 is slidably connected to the longitudinal loading drive device 303. The vertical loading drive cylinder 305 is installed on the transverse loading slide 304, and the output end of the vertical loading drive cylinder 305 is connected to the vertical loading drive plate 306. The first drive cylinder 307 and the second drive cylinder 309 are respectively installed at both ends of the vertical loading drive plate 306. The output end of the first drive cylinder 307 is connected to the first staggered clamping plate 308, and the output end of the second drive cylinder 309 is connected to the second staggered clamping plate 310.

[0046] Among them, the loading bracket 301 plays a role in fixedly supporting each structure of the iron core loading assembly 300. First of all, the conveyor belt device 302 is composed of two parallel conveyor belts. Among them, one conveyor belt is used to transfer the fixture tray carrying the iron core, and the other conveyor belt is used to transfer the empty fixture tray. Moreover, the rotation directions of the two conveyor belts are exactly opposite. At the same time, the longitudinal loading drive device 303 drives the transverse loading slide 304 to reciprocate in the longitudinal direction. And the vertical loading drive cylinder 305 drives the vertical loading drive plate 306 to reciprocate in the vertical direction. Furthermore, it can enable the first staggered clamping plate and the second staggered clamping plate 310 to reciprocate in the longitudinal and vertical directions to realize the iron core loading action.

[0047] Specifically, when the first staggered clamping plate 308 and the second staggered clamping plate 310 need to transfer the materials in the fixture tray on the conveyor belt device 302, first of all, the vertical loading drive cylinder 305 enters the working state. Thus, the vertical loading drive cylinder 305 drives the vertical loading drive plate 306 to approach the fixture tray. Then, the first drive cylinder 307 and the second drive cylinder 309 enter the working state at the same time. As a result, the first staggered clamping plate 308 and the second staggered clamping plate 310 move relative to each other at the same time, that is, the distance between the first staggered clamping plate 308 and the second staggered clamping plate 310 approaches each other to clamp the iron core. It is worth noting that the number of the first staggered clamping plate 308 and the second staggered clamping plate 310 is multiple to achieve high-efficiency iron core transfer. At the same time, the driving mode of the longitudinal loading drive device 303 can be the driving mode of a motor plus a lead screw.

[0048] In this embodiment, a fixture plate commutation assembly 400 is further connected to the loading transverse slide plate 304. The fixture plate commutation assembly 400 includes a commutation driving cylinder 410, a commutation slide rail 420, a commutation connecting plate 430, a first commutation jaw cylinder 440, and a second commutation jaw cylinder 450. The commutation driving cylinder 410 is installed on the loading transverse slide plate 304, the commutation slide rail 420 is installed on the side wall of the loading vertical driving plate 306, the commutation connecting plate 430 is slidably connected to the commutation slide rail 420, and the output end of the commutation driving cylinder 410 is connected to the commutation connecting plate 430. The first commutation jaw cylinder 440 and the second commutation jaw cylinder 450 are respectively connected to both sides of the commutation connecting plate 430.

[0049] Among them, the fixture plate commutation assembly 400 is mainly used to perform a commutation action on the empty fixture plate that has transferred the iron core through the iron core loading assembly 300 in the conveyor belt device 302, that is, to transfer the empty fixture plate to another conveyor belt for reflux.

[0050] Specifically, when the fixture plate commutation assembly 400 needs to perform a commutation action, first, the loading transverse slide plate 304 is driven by the loading longitudinal driving device 303 to make the loading transverse slide plate 304 located above the conveyor belt device 302. Then, the commutation driving cylinder 410 enters the working state, so that the commutation driving cylinder 410 drives the commutation connecting plate 430 to move in the vertical direction on the commutation slide rail 420, and further makes the first commutation jaw cylinder 440 and the second commutation jaw cylinder 450 approach the empty fixture plate on the conveyor belt device 302 to clamp the empty fixture plate and transfer it to another conveyor belt in the conveyor belt device 302, thereby realizing the commutation action of the fixture plate.

[0051] In this embodiment, the iron core pre-rounding assembly 500 includes a pre-rounding bracket 510, a pre-rounding driving device 520, a pre-rounding support table 530, a pre-rounding assembly table 540, a pre-rounding driving motor 550 for driving the pre-rounding assembly table 540 to rotate, a pre-rounding limit notch 560, and a pre-rounding lifting cylinder 570 for driving the pre-rounding assembly table 540 to perform vertical reciprocating motion. The pre-rounding bracket 510 is installed on the frame 100, the pre-rounding driving device 520 is installed on the pre-rounding bracket 510, the output end of the pre-rounding driving device 520 is connected to the pre-rounding support table 530, the pre-rounding driving motor 550 is installed under the pre-rounding support table 530, the pre-rounding assembly table 540 is installed on the pre-rounding support table 530, and a pre-rounding limit notch 560 is provided on the periphery of the pre-rounding assembly table 540. The pre-rounding lifting cylinder 570 is arranged under the pre-rounding support table 530, and the output end of the pre-rounding lifting cylinder 570 is connected to the pre-rounding assembly table 540.

[0052] Among them, the preformed circular bracket 510 plays a role in fixing and supporting each structure in the iron core preformed circular component 500. At the same time, when the iron core flipping and accommodating component 200 and the iron core inserting component 600 cooperate with each other to transfer a single iron core into the iron core preformed circular component 500, first, the iron core enters into the preformed circular assembly table 540, and the preformed circular drive motor 550 drives the preformed circular assembly table 540 to rotate a certain angle, so that multiple iron cores are successively loaded into the preformed circular assembly table 540. And the preformed circular limit notch 560 can temporarily fix the preformed circular assembly table 540 under the iron core inserting component 600, thereby improving the stability and accuracy of loading the iron core into the preformed circular assembly table 540. At the same time, when the iron core is inserted into the preformed circular assembly table 540, the preformed circular lifting cylinder 570 first lifts the preformed circular assembly table 540 by a certain height to facilitate cooperation with the iron core inserting component 600, thereby improving the convenience of the iron core entering the preformed circular assembly table 540. Further, the driving mode of the preformed circular driving device 520 is a motor plus a lead screw, and at the same time, the preformed circular driving device 520 can drive the preformed circular support table 530 to slide on the preformed circular bracket 510, so that the preformed circular assembly table 540 approaches the stator fastening component 700 after all the iron cores are loaded.

[0053] In this embodiment, the iron core inserting component 600 includes an inserting bracket 610, a first pressing driving device 620, a lower pressing head 630, a second pressing driving device 640, and a stator inner ring support block 650. The inserting bracket 610 is installed on the frame 100. The first pressing driving device 620 is installed at the end of the inserting bracket 610. The output end of the first pressing driving device 620 is connected to the lower pressing head 630. The lower pressing head 630 faces the iron core flipping and accommodating component 200. The second pressing driving device 640 is also installed at the end of the inserting bracket 610. The output end of the second pressing driving device 640 is connected to the stator inner ring support block 650.

[0054] Among them, the cartridge bracket 610 plays a role in fixing and supporting each structure of the iron core cartridge assembly 600. At the same time, when the iron core cartridge assembly 600 needs to insert the iron core in the iron core flipping and accommodating assembly 200, first, the first pressing drive device 620 enters the working state. The first pressing drive device 620 drives the lower pressing head 630 to move in the vertical direction. Thus, the lower pressing head 630 inserts the iron core in the iron core flipping and accommodating assembly 200 into the iron core pre-forming circular assembly 500. At the same time, when the iron core pre-forming circular assembly 500 completes the pre-forming circular action of the iron core and moves to a position matching that of the stator fastening assembly 700, the second pressing drive device 640 enters the working state. Thus, the second pressing drive device 640 drives the stator inner ring support block 650 to reciprocate in the vertical direction. The stator inner ring support block 650 is mainly used to support the inside of the stator when the stator fastening assembly 700 presses the stator, so as to prevent the stator from deforming during the pressing process.

[0055] In this embodiment, the stator fastening assembly 700 includes two relatively arranged fastening brackets 710, two relatively arranged fastening drive cylinders 720 and a fastening plate 730. The fastening brackets 710 are installed on the frame 100. The fastening drive cylinders 720 are installed at the ends of the fastening brackets 710. The output ends of the fastening drive cylinders 720 are connected to the fastening plate 730. The two fastening drive cylinders 720 drive the two fastening plates 730 to move towards or away from each other.

[0056] Among them, when the iron core pre-forming circular assembly 500 completes the pre-forming circular action of the stator, the iron core pre-forming circular assembly 500 moves to a position matching that of the stator fastening assembly 700. At this time, the two relatively arranged fastening drive cylinders 720 enter the working state. Thus, the fastening drive cylinders 720 drive the two fastening plates 730 to move relatively. The two approaching fastening plates 730 perform a clamping and fixing action on the formed stator, thus completing the function of the stator fastening assembly 700.

[0057] In this embodiment, the stator coding and detection assembly 800 includes a laser coding machine 810, a coding rotating cylinder, a stator support platform 830, a code scanning and identifying device 840 and an image detection sensor 850 for detecting whether the stator accommodated on the stator support platform 830 is qualified. The coding rotating cylinder 820 is arranged on the frame 100. The stator support platform 830 is connected to the coding rotating cylinder 820. The laser coding machine 810 is installed on one side of the stator support platform 830. The code scanning and identifying device 840 is connected to the other side of the stator support platform 830. The image detection sensor 850 is arranged above the code scanning and identifying device 840, and the image detection sensor 850 faces the stator support platform 830. The coding rotating cylinder 820 drives the stator support platform 830 to rotate between the laser coding machine 810 and the code scanning and identifying device 840.

[0058] Among them, after the stator fastening assembly 700 completes the fastening and pressing action on the stator, the stator is transferred into the stator support platform 830. At this time, the coding rotation cylinder 820 enters the working state, so that the coding rotation cylinder 820 drives the stator support platform 830 to rotate. When the stator approaches the laser coding machine 810, the laser coding machine 810 performs a laser coding action on the stator on the stator support platform 830. Thus, when the stator support platform 830 continues to rotate and matches the position of the code scanning and recognition device 840, the code scanning and recognition device 840 recognizes the code that has been coded on the stator, so as to obtain the state information of the stator. Moreover, the image detection sensor 850 can detect the lead situation of the stator on the stator support platform 830 in real time to avoid situations such as lead dislocation of the stator, thereby improving the quality monitoring of the stator.

[0059] In this embodiment, a core transfer assembly 900 is further installed on the frame 100. The core transfer assembly 900 includes a transfer bracket 910, a first linkage shaft 920, a second linkage shaft 930, a transfer driving electric cylinder 940, and a transfer jaw cylinder 950.

The transfer jaw cylinder 950 is connected to the output end of the transfer driving electric cylinder 940.

[0060] Among them, the core transfer assembly 900 is mainly used to transfer the qualified stator processed by the coding and detection assembly into an external device or transfer the unqualified stator in the coding and detection assembly into the unqualified product accommodating station 960.

[0061] Specifically, the transfer bracket 910 mainly plays a role in fixedly supporting each structure in the core transfer assembly 900. At the same time, the first linkage shaft 920, the second linkage shaft 930, and the transfer bracket 910 cooperate with each other to form a core transfer assembly 900 with four degrees of freedom. The transfer driving electric cylinder 940 drives the transfer jaw cylinder 950 to rotate at multiple angles, and the transfer jaw cylinder 950 clamps and fixes the stator to facilitate the transfer of the stator.

At the same time, the core pre-forming circle assembly 500 rotates to enable the segmented stator to complete the pre-forming circle action in the core pre-forming circle assembly 500. S4. Stator fastening: After the stator completes the pre-forming circle action in the core pre-forming circle assembly 500, it enters the stator fastening assembly 700, and the stator fastening assembly 700 clamps and fixes the formed stator. S5. Coding and detection: The stator after being fastened by the stator fastening assembly 700 enters the stator coding and detection assembly 800, and the stator coding and detection assembly 800 codes, scans the code of the stator, and detects whether the arrangement of the internal leads of the stator is qualified.

[0064] The segmented stator pre-forming circle machine includes a frame 100, a core flipping and accommodating assembly 200 for flipping and accommodating the core, a core feeding assembly 300 for transferring the core into the core flipping and accommodating assembly 200, a core pre-forming circle assembly 500, a core insertion assembly 600 for inserting the core in the core flipping and accommodating assembly 200 into the core pre-forming circle assembly 500, a stator fastening assembly 700 for performing a fastening action on the formed stator, and a stator coding and detection assembly 800 for coding and detecting the pre-formed stator. The core feeding assembly 300 and the core flipping and accommodating assembly 200 are both arranged on the frame 100. The core pre-forming circle assembly 500 is arranged on one side of the core flipping and accommodating assembly 200.
