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.

[0032] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of this phrase in the specification are not necessarily all referring to the same embodiment, nor are they independent or alternative embodiments mutually exclusive of other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0034] The material accommodating component 200 is installed on the frame 100, the material taking component 300 is installed on the frame 100, the material taking component 300 transfers the end cap in the material accommodating component 200 to the rotating alignment component 400, the pin inspection component 500, the rotating alignment component 400, and the wire straightening component 600 are sequentially arranged beside the material accommodating component 200, and the core feeding component 700 is installed above the wire straightening component 600.

[0035] Among them, when the iron core end cover assembling machine of the present invention performs the assembling action on the end cover and the stator, first, the material taking component 300 enters the working state. The material taking component 300 transfers the end cover in the material accommodating component 200 to the rotating positioning component 400. The rotating positioning component 400 performs the precise positioning action on the end cover and keeps the lead wire on the end cover facing a fixed position. After the rotating positioning component 400 completes the precise positioning and rotating positioning actions on the end cover, the material taking component 300 transfers the end cover to the pin inspection component 500 again. The pin inspection component 500 checks whether there are problems such as pin deformation or missing on the end cover. At this time, the iron core feeding component 700 clamps the external stator and transfers it into the wire arranging component 600. Then, the material taking component 300 clamps the end cover that has completed the pin inspection action and transfers it into the wire arranging component 600, and assembles the end cover and the stator together, that is, the assembling action on the end cover and the stator is completed. Then, the wire arranging component 600 arranges the lead wires on the assembled end cover and stator, and thus the entire working process of the present invention is completed.

[0036] In this embodiment, the material accommodating component 200 includes a material support 210 and a plurality of material tray accommodating parts for accommodating material trays. The material support 210 is fixedly installed on the frame 100, and the material tray accommodating parts are installed at the end of the material support 210.

[0037] Among them, the material support 210 plays a role of fixing and supporting the material tray accommodating parts. At the same time, the material tray accommodating parts are used to place the material trays with end covers from the outside. Of course, the material trays can also be temporarily stored on the frame 100 below the material tray accommodating parts to improve the convenience of feeding the material trays.

[0038] In this embodiment, the material taking component 300 includes a material taking support 310, a material taking longitudinal driving device 320, a material taking transverse driving device 330, a material taking vertical driving device 340, and a plurality of material taking jaw cylinders 350. The material taking support 310 is installed on the frame 100. The material taking longitudinal driving device 320 is installed at the end of the material taking support 310. The material taking transverse driving device 330 is connected to the output end of the material taking longitudinal driving device 320. The material taking vertical driving device 340 is connected to the output end of the material taking transverse driving device 330. The plurality of material taking jaw cylinders 350 are connected to the output end of the material taking vertical driving device 340.

[0039] Among them, the material taking support 310 plays a role in fixing and supporting each structure within the material taking assembly 300. The material taking longitudinal driving device 320 drives the material taking transverse driving device 330 to reciprocate longitudinally. At the same time, the material taking transverse driving device 330 drives the material taking vertical driving device 340 to reciprocate transversely. Furthermore, the material taking vertical driving device 340 drives the material taking jaw cylinder 350 to reciprocate vertically. Thus, with the mutual cooperation of the material taking longitudinal driving device 320, the material taking transverse driving device 330, and the material taking vertical driving device 340, it is possible to achieve position transformation of the material taking jaw cylinder 350 at various angles, thereby improving the movement of the material taking assembly 300 in all directions, and further improving the all-round transfer of the material by the material taking assembly 300.

[0040] In this embodiment, the rotation and positioning assembly 400 includes a rotation and positioning support 410, a plurality of positioning slide rods 420, a positioning plate 430, a positioning disk 440, a positioning driving cylinder 450, a material rotation disk 460, a rotation driving motor 470, and a laser sensor 480 for detecting the material lead on the material rotation disk 460. The rotation and positioning support 410 is installed on the frame 100. The plurality of positioning slide rods 420 are installed on the rotation and positioning frame 100. The positioning plate 430 is slidably connected to the end of the positioning slide rod 420. The positioning disk 440 is installed on the positioning plate 430. The positioning driving cylinder 450 is installed on the rotation and positioning support 410, and the output end of the positioning driving cylinder abuts against the positioning plate 430. The rotation driving motor 470 is installed on the rotation and positioning support 410, and the output end of the rotation driving motor 470 is connected to the material rotation disk 460. The material rotation disk 460 is exactly located above the positioning disk 440. The laser sensor 480 is installed on the rotation and positioning support 410, and the laser sensor 480 faces the material rotation disk 460.

[0041] Among them, the rotary positioning bracket 410 plays a role of fixed support for each structure in the rotary positioning component 400. When the end cover enters the rotary positioning component 400 from the material containing component 200 under the drive of the material picking component 300, first, the end cover is placed on the material rotating disk 460. At this time, the positioning drive cylinder 450 enters the working state, so that the positioning drive cylinder 450 drives the positioning plate 430 to move vertically on the positioning slide bar 420. At the same time, the positioning disk 440 moves with the positioning plate 430. The positioning disk 440 is close to the end cover in the material rotating disk 460, and the end cover in the material rotating disk 460 is precisely positioned to ensure that the pin of the end cover is facing a fixed direction. At the same time, the rotary drive The motor 470 drives the material on the material rotating disk 460 to reciprocate to ensure that the end cap leads are all located on the same side of the laser sensor 480. First, the number of leads on the end cap is usually three. When the end cap is placed in the material rotating disk 460, first, the rotation drive motor 470 drives the material rotating disk 460 to rotate. When the laser sensor 480 detects that the leads on the end cap pass through the detection range of the laser sensor 480 for the first time, at this time, the rotation drive motor 470 drives the material rotating disk 460 to move in the opposite direction by 90-120°, thereby ensuring that the three leads on the end cap are all located on the same side of the laser sensor 480, so that the position of the end cap leads is fixed, which facilitates the production and processing of the end cap in subsequent steps.

[0042] In this embodiment, a plurality of positioning grooves 441 for precisely positioning the pins of the inner end cover of the material rotating disk 460 are formed on the positioning disk 440 .

[0043] The number of the positioning grooves 441 is the same as the number of the pins on the end cover, and the arrangement of the positioning grooves 441 is exactly the same as that of the pins on the end cover.

[0044] In this embodiment, the pin inspection component 500 includes a pin inspection bracket 510, a material placement tray 520, a material receiving clamping claw cylinder 530, a plurality of laser detection sensors 540 for detecting whether the material pins in the material placement tray 520 are qualified, and a material driving component 550 for rotating the material placement tray 520. The pin inspection bracket 510 is installed on the frame 100, the material placement tray 520 is arranged on the upper side of the pin inspection bracket 510, the material driving component 550 is arranged on the lower side of the material placement tray 520, the material receiving clamping claw cylinder 530 is installed on the upper side of the frame 100, and the positions of the material receiving clamping claw cylinder 530 and the material placement tray 520 are mutually adapted, and the laser detection sensors 540 are all installed on the frame 100, and the laser detection sensors 540 are facing the material placement tray 520.

[0045] Among them, the pin inspection bracket 510 plays a role in fixing and supporting each structure within the pin inspection assembly 500. At the same time, after the end cap completes the fine positioning and rotation positioning actions on the rotation positioning assembly 400, the material taking assembly 300 transfers the end cap from the rotation positioning assembly 400 to the pin inspection assembly 500. First, the material taking assembly 300 places the material on the material receiving jaw cylinder 530. Subsequently, the material driving assembly 550 transfers the material on the material receiving jaw cylinder 530 to the material placement tray 520. At this time, multiple laser detection sensors 540 detect whether the pins of the end cap on the material placement tray 520 are damaged or bent to ensure that the pins of the end cap are qualified. Subsequently, the material driving assembly 550 drives the material placement tray 520 to rotate, thereby comprehensively detecting the outer side of the end cap to ensure the yield rate of the end cap, and then completing the pin inspection action of the end cap.

[0046] In this embodiment, the material driving assembly 550 includes a vertical driving device 551, a vertical adjustment slide rod 552, a material receiving plate 553, and a material driving motor 554 for driving the material placement tray 520 to rotate. The vertical driving device 551 is installed on the pin inspection bracket 510. The vertical adjustment slide rod 552 is connected to the output end of the vertical driving device 551. The end of the vertical adjustment slide rod 552 is connected to the material receiving plate 553. The material driving motor 554 is connected to the pin inspection bracket 510, and the output end of the material driving motor 554 is connected to the material placement tray 520.

[0047] Among them, the driving mode of the vertical driving device 551 is mainly the driving mode of a motor plus a lead screw. The vertical driving device 551 drives the vertical adjustment slide rod 552 to perform reciprocating motion in the vertical direction, thereby driving the material receiving plate 553 to perform reciprocating motion up and down. After the end cap is transferred into the material receiving jaw cylinder 530, the vertical driving device drives the vertical adjustment slide rod 552 to move upward, so that the vertical adjustment slide rod 552 drives the material receiving plate 553 to approach the material receiving jaw cylinder 530. After the material receiving plate 553 approaches the material receiving jaw cylinder 530, the material receiving jaw cylinder 530 releases the end cap, so that the end cap falls onto the material receiving plate 553. Subsequently, the material receiving plate 553 moves downward. When the material receiving plate 553 passes by the material placement tray 520, the end cap is placed in the material placement tray 520, thus realizing the feeding action of the material. Further, the material driving motor 554 is used to drive the material placement tray 520 to perform a rotation action.

[0048] In this embodiment, the wire arranging assembly 600 includes a wire arranging bracket 610, a wire arranging driving device 611, a wire arranging material accommodating part 612, a wire arranging fixing plate 613, a first adjusting turntable 620, a plurality of lead pressing blocks 630, an adjusting middle turntable 640, a plurality of lead wire deflecting blocks 650, a second adjusting turntable 660, a third adjusting turntable 670, a wire arranging bottom plate 680, and a plurality of driving motors 690 for driving the first adjusting turntable 620, the second adjusting turntable 660, and the third adjusting turntable 670 to rotate. The wire arranging bracket 610 is installed on the frame 100. The wire arranging driving device 611 is connected to the wire arranging bracket 610, and the output end of the wire arranging driving device 611 is connected to the wire arranging material accommodating part 612. The wire arranging bottom plate 680 is installed on the wire arranging bracket 610. The third adjusting turntable 670 is rotatably connected inside the wire arranging bottom plate 680. The second adjusting turntable 660 is accommodated inside the third adjusting turntable 670. The adjusting middle turntable 640 is buckled with the wire arranging bottom plate 680. A plurality of lead wire deflecting blocks 650 are arranged between the second adjusting turntable 660 and the adjusting middle turntable 640. The first adjusting turntable 620 is installed on one side of the adjusting middle turntable 640. The wire arranging fixing plate 613 is buckled with the adjusting middle turntable 640, and the lead pressing blocks 630 are installed between the adjusting middle turntable 640 and the wire arranging fixing plate 613. A limiting groove 632 for limiting the lead wire is formed on the lead pressing blocks 630. A plurality of driving motors 690 are arranged on the periphery of the wire arranging bracket 610.

[0049] Among them, the wire arranging bracket 610 plays a role in fixedly supporting each structure of the wire arranging assembly 600. After the end cover passes through the pin inspection in the pin inspection assembly 500, first, the wire arranging driving device 611 drives the wire arranging material accommodating part 612 to extend out of the wire arranging fixing plate 613. The iron core feeding assembly 700 transfers the external stator to the wire arranging material accommodating part 612. At this time, the material taking assembly 300 transfers the end cover into the stator in the wire arranging material accommodating part 612, thereby completing the assembly of the stator and the end cover.

[0050] Thereafter, the wire arranging driving device 611 drives the wire arranging material accommodating part 612 to be received into the wire arranging fixing plate 613. At this time, one of the multiple driving motors 690 drives the second adjusting turntable 660 to rotate, so that the wire leading and wire deflecting block 650 moves in the direction close to the wire arranging material accommodating part 612. When the wire leading and wire deflecting block 650 moves to a position beyond the wire on the end cover, one of the multiple driving motors 690 drives the third adjusting turntable 670 to rotate. At this time, the wire leading and wire deflecting block 650 rotates with the rotation of the third adjusting turntable 670. When the wire leading and wire deflecting block 650 is in contact with the position of the wire on the end cover, the second adjusting turntable 660 rotates in the reverse direction, so that the wire leading and wire deflecting block 650 retracts a certain distance until the wire leading and wire deflecting block 650 abuts against the wire on the end cover. Subsequently, one of the multiple driving motors 690 drives the first adjusting turntable 620 to rotate, so that the first adjusting turntable 620 drives the wire abutting block 630 to move in the direction close to the end cover until the wire abutting part is in contact with the wire on the end cover, so that the wire abutting block 630 and the wire leading and wire deflecting block 650 cooperate with each other to complete the wire arranging action for the wire on the end cover. Among them, the driving mode of the wire arranging driving device 611 can be a driving mode of a motor plus a lead screw.

[0051] In this embodiment, a first adjusting groove 621 for restricting the wire abutting block 630 to approach or move away from the center of the first adjusting turntable 620 is formed on the first adjusting turntable 620. A first limiting groove 622 for restricting the wire abutting block 630 to maintain linear motion is formed on the side of the adjusting middle turntable 640 facing the first adjusting turntable 620. A second adjusting groove 661 for restricting the wire leading and wire deflecting block 650 to approach or move away from the center of the second adjusting turntable 660 is formed on the second adjusting turntable 660. A second limiting groove 662 for restricting the wire leading and wire deflecting block 650 to maintain linear motion is formed on the side of the adjusting middle turntable 640 facing the second adjusting turntable 660.

[0052] Among them, when the first adjusting turntable 620 rotates, the wire abutting block 630 moves towards the center position of the first adjusting turntable 620. Thus, the first limiting groove 622 is rectangular, so as to ensure that the wire abutting block 630 makes a linear reciprocating motion.
