[0027] like Figures 1 to 5 As shown, the rotor commutator assembly device 100 provided in this embodiment includes: a base plate 10; a rotation adjustment device 20 for rotating the rotor core 90 by a preset angle; a feeding clamping device 30 for clamping the rotor core 90 on the rotation adjustment device 20 and making the axis of the rotor core 90 perpendicular to the surface of the base plate 10; a holding device 40 including a holding bracket 41 and a fixing seat assembly 42 for placing and fixing the rotor core 90 of the feeding clamping device 30, the fixing seat assembly 42 being liftably mounted on the holding bracket 41; an assembly support device 50 for placing the commutator 92 and coaxially arranging the commutator 92 with the rotor core 90, the assembly support device 50 being located below the fixing seat assembly 42; and a pressing device 60 for driving the fixing seat assembly 42 to move relative to the holding bracket 41 to connect the rotor core 90 with the commutator 92.

[0028] The aforementioned rotor commutator assembly device 100 includes a rotation adjustment device 20, a feeding clamping device 30, a holding device 40, an assembly support device 50, and a pressing device 60. The rotation adjustment device 20 rotates the rotor core 90 by a preset angle. The feeding clamping device 30 clamps the rotor core 90 on the rotation adjustment device 20 and feeds the rotor core 90 vertically into the fixing seat assembly 42 of the holding device 40 for fixation. The assembly support device 50 is located below the fixing seat assembly 42. The commutator 92 is supported on the assembly support device 50 and coaxially arranged with the rotor core 90. The pressing device 60 presses down the rotor core 90 on the holding device 40 to connect the rotor core 90 with the commutator 92. In this way, the production and manufacturing costs can be reduced, the assembly efficiency can be improved, and time and labor can be saved.

[0029] See Figure 1 and Figure 2The rotor commutator assembly device 100 provided in this embodiment is used to assemble the commutator 92 onto the rotating shaft 91 of the rotor core 90. The rotor commutator assembly device 100 includes a rotation adjustment device 20, a feeding clamping device 30, a holding device 40, an assembly support device 50, and a pressing device 60. In this embodiment, the rotor commutator assembly device 100 includes a base plate 10 and the rotation adjustment device 20, feeding clamping device 30, holding device 40, assembly support device 50, pressing device 60, feeding device 70, and transferring device 80 supported on the base plate 10. The assembly support device 50 is located below the holding device 40 and the pressing device 60. The rotation adjustment device 20 and the feeding device 70 are located on the periphery of the assembly support device 50. The feeding clamping device 30 can clamp the rotor core 90 on the conveyor line 110 and send it to the rotation adjustment device 20. After the rotor core 90 rotates at a preset angle, it is sent into the holding device 40. The material transfer device 80 can send the commutator 92 on the feeding device 70 to the assembly support device 50. Then, the pressing device 60 moves the rotor core 90 on the holding device 40 down and presses it into the commutator 92 to complete the assembly of the rotor.

[0030] See Figure 3 The rotation adjustment device 20 provided in this embodiment is used to rotate the rotor core 90 by a preset angle. The rotation adjustment device 20 includes a support 21 for placing the rotor core 90 and a rotation drive mechanism 22 for driving the rotor core 90 to rotate. The support 21 is fixed on the base plate 10. The rotor core 90 can be placed horizontally on the support 21 or vertically on the support 21. In this embodiment, the support 21 has two support arms 211 spaced apart. The rotor core 90 is placed horizontally on the support arms 211 of the support 21. Each support arm 211 has a V-shaped groove for the rotor shaft 91 of the rotor core 90 to be inserted. In this way, after the rotor core 90 is inserted, its axis can be positioned. Then, the rotor core 90 is rotated by the rotation drive mechanism 22 to a preset angle and then gripped into the holding device 40 for assembly.

[0031] Please continue reading Figure 3In this embodiment, the rotary drive mechanism 22 includes a support base 221 disposed on one side of the bearing seat 21, a swing bracket 222 rotatably mounted on the support base 221, a swing power component 223 for driving the swing bracket 222 to rotate, and a rotary drive assembly 224 mounted on the swing bracket 222. The swing power component 223 is, but is not limited to, a rotary cylinder. The swing power component 223 is connected to the swing bracket 222. Under the drive of the swing power component 223, the swing bracket 222 can be flipped up and down. The rotary drive assembly 224 includes components for contacting the surface of the rotor core 90. The rotating drive belt 225 is rotatably supported on the swing bracket 222. The rotating drive belt 225 is rotatably supported on the swing bracket 222. The rotating power component 226 is, but is not limited to, a motor. It is connected to the rotating drive belt 225 and can make the rotating drive belt 225 rotate. Thus, after the rotor core 90 is placed in the support seat 21, the rotating power component 226 drives the rotating drive belt 225 to rotate. The swing power component 223 controls the swing bracket 222 to flip downward so that the rotating drive belt 225 contacts the rotor core 90, thereby driving the rotor core 90 to rotate.

[0032] See Figure 3 In this embodiment, the support 21 is provided with an anti-rotation cylinder 23. The anti-rotation cylinder 23 has two opening and closing anti-rotation fingers. In this way, when the rotor core 90 is detected to rotate to a predetermined position, the anti-rotation cylinder 23 can clamp the rotor core 90, so that the rotor core 90 stops rotating. At the same time, the swing power component 223 controls the swing bracket 222 to reset and flip upward.

[0033] See Figure 3 In this embodiment, the support base 21 is provided with a positioning plate 24 for abutting against the rotor core 90 and a pushing power member 25 for pushing the rotor core 90 so that the rotor core 90 moves along the axis of the rotor core 90 toward the positioning plate 24. The pushing power member 25 is fixed on the support base 21 and the pushing power member 25 is, but is not limited to, a cylinder. In this way, the rotor core 90 can be pushed toward the positioning plate 24 by the pushing power member 25, thereby positioning the position of the rotor core 90.

[0034] See Figure 2 and Figure 3The feeding clamping device 30 provided in this embodiment is used to clamp the rotor core 90 on the rotation adjustment device 20 and rotate the rotor core 90 so that the axis of the rotor core 90 is perpendicular to the surface of the substrate 10. In this embodiment, the feeding clamping device 30 includes a feeding mounting frame 31 supported on the substrate 10, a feeding translation bracket 32 ​​movably mounted on the feeding mounting frame 31, a feeding lifting bracket 33 movably mounted on the feeding translation bracket 32, and a rotating mounting base 34 rotatably supported on the feeding lifting bracket 33. The rotating device 34 is driven to rotate by a rotating mounting member 35 and a feeding clamping assembly 36 mounted on the rotating device 34. The rotating device 34 forms a 45° angle with the surface of the substrate 10. The rotating device 34 is rotatably mounted on the feeding lifting bracket 33 with an axis perpendicular to the center of its surface. The number of feeding clamping assemblies 36 is, but not limited to, two. The two feeding clamping assemblies 36 are arranged 180° apart. The one located below the other is arranged vertically, and the one located above the other is arranged horizontally.

[0035] See Figure 2 and Figure 4 The holding device 40 provided in this embodiment includes a holding bracket 41 and a fixing seat assembly 42 for inserting and fixing the rotor core 90 of the feeding clamping device 30. The fixing seat assembly 42 is movably mounted on the holding bracket 41. In this embodiment, the fixing seat assembly 42 includes a fixing seat 421 movably mounted on the holding bracket 41, two clamping plates 422 mounted on the fixing seat 421 for clamping the rotor core 90, and a clamping plate power member 423 for driving the two clamping plates 422 to move to clamp and release the rotor core 90. The two clamping plates 422 are substantially on the same plane. The fixed seat 421 is provided with a clearance groove to allow the feeding clamping assembly 36 and the rotor core 90 to pass through when the feeding clamping assembly 36 feeds the rotor core 90. The number of clamping plate power members 423 is not limited to two. The two clamping plate power members 423 correspond one-to-one with the two clamping plates 422. The clamping plate power members 423 are, but are not limited to, cylinders. The clamping plate power members 423 can drive the corresponding clamping plates 422 to move horizontally. In this way, after the feeding clamping assembly 36 feeds the rotor core 90, the two clamping plates 422 move towards each other under the drive of the clamping plate power members 423 and fix the rotor core 90 on the fixed seat 421.

[0036] See Figure 2 and Figure 4In this embodiment, the retaining bracket 41 includes a retaining base plate 411 and retaining guide posts 412 mounted on the retaining base plate 411. The number of retaining guide posts 412 is not limited to four. The four retaining guide posts 412 are respectively mounted at the four corners of the fixed seat 421. The fixed seat 421 is movably connected to the retaining guide posts 412. At least two of the retaining guide posts 412 are provided with return springs 413. The two ends of the return springs 413 abut against the retaining base plate 411 and the fixed seat 421 respectively. Thus, under the pressure of the pressing device 60, the rotor core 90 and the fixed seat 421 will move downward (lower in the figure) and compress the return springs 413. After the pressure is released, the return springs 413 cause the fixed seat 421 to drive the rotor core 90 to move upward (upper in the figure) to reset.

[0037] See Figure 2 and Figure 4 The pressing device 60 provided in this embodiment is used to drive the fixed seat assembly 42 to move relative to the retaining bracket 41 so that the rotor core 90 is connected to the commutator 92. In this embodiment, the pressing device 60 includes a pressing support frame 61 supported on the base plate 10, a pressing head 62 for abutting against the rotor core 90, and a pressing power member 63 for driving the pressing head 62 to rise and fall. The retaining base plate 411 of the retaining bracket 41 is supported on the pressing support frame 61. The pressing power member 63 is, but is not limited to, an electric cylinder. The pressing head 62 can be driven to rise and fall relative to the pressing support frame 61 by the pressing power member 63. In this way, the pressing power member 63 controls the pressing head 62 to move downward to press the rotor core 90 located below it to move downward (downward in the figure), thereby completing the assembly of the commutator 92 on the rotor core 90.

[0038] See Figure 2 , Figure 4 and Figure 5The assembly support device 50 provided in this embodiment is used to place the commutator 92 and to make the commutator 92 coaxial with the rotor core 90. The assembly support device 50 is located below the fixed base assembly 42. In this embodiment, the assembly support device 50 includes an assembly support base 51, a circular assembly carrier 52 rotatably mounted in the assembly support base 51, and an assembly power member 53 for rotating the assembly carrier 52. The assembly power member 53 is, but is not limited to, a cylinder. The assembly carrier 52 has an assembly base surface 521 for abutting against the hook portion 921 on the commutator 92. The assembly support base 51 has, but is not limited to, a circular cross-section. The assembly base surface 521 of the assembly carrier 52 is shaped like a cylinder at its center. The assembly tray 52 has an assembly hole 522 for inserting the commutator 92. The assembly base surface 521 of the assembly tray 52 is provided with a plurality of limiting protrusions 523 for inserting into the gap between adjacent hook portions 921. The number of limiting protrusions 523 is not limited to three. The three limiting protrusions 523 are arranged at equal intervals along the circumference of the assembly tray 52 and are located at the edge of the assembly hole 522. In this way, after the commutator 92 is inserted, the assembly tray 52 is rotated back and forth by the assembly power member 53. Under its own gravity, the commutator 92 will slide downward (downward in the figure). At the same time, the limiting protrusions 523 move into the gap between adjacent hook portions 921, thereby limiting the commutator 92 circumferentially. It is worth mentioning that after the commutator 92 slides into the limiting protrusion 523, the assembly carrier 52 can be rotated by the assembly power component 53, so that the commutator 92 can be rotated to an angle that meets the assembly requirements. Then, the rotor core 90 is moved downward to push the shaft 91 into the commutator 92 to complete the assembly.

[0039] See Figure 2 , Figure 4 and Figure 5 In this embodiment, an operating lever 54 is connected to the bottom of the assembly tray 52, and a limiting groove 511 for the operating lever 54 to swing is provided on the assembly support base 51. The operating lever 54 forms an operating slide groove 541. A push-pull shaft 55 is connected to the assembly power component 53. The push-pull shaft 55 can move along the axis of the push-pull shaft 55 under the drive of the assembly power component 53. The outer end of the push-pull shaft 55 is movably connected to the operating slide groove 541 of the operating lever 54. In this way, by the translation of the push-pull shaft 55 relative to the operating slide groove 541, the operating lever 54 and the assembly tray 52 can be pulled to rotate back and forth so that the hook part 921 of the commutator 92 falls onto the assembly base surface 521.

[0040] See Figure 5 A cover plate 56 is detachably connected to the assembly support 51 to limit the upward (upper part in the figure) movement of the assembly tray 52.

[0041] See Figure 2 and Figure 4In this embodiment, the feeding device 70 is, but is not limited to, a vibratory feeder for providing the commutator 92. The transferring device 80 includes a transferring mounting frame 81 and a transferring clamping assembly 82 movably disposed on the transferring mounting frame 81. The transferring clamping assembly 82 can clamp the commutator 92 on the feeding device 70 and deliver the commutator 92 to the assembly support 51. The assembly support 50 also includes a sliding base plate 57 and a sliding power component capable of driving the sliding base plate 57 to move relative to the pressing device 60 on a plane parallel to the surface of the substrate 10. 58. The assembly support 51 is fixed on the sliding base plate 57, which is movably mounted on the press-fit support frame 61. The sliding power component 58 is, but is not limited to, a cylinder. Thus, the sliding power component 58 drives the sliding base plate 57 and the assembly support 51 to move below the material transfer device 80. After the material transfer clamping assembly 82 places the commutator 92 flat on the assembly support 51, the sliding power component 58 drives the sliding base plate 57 and the assembly support 51 to move below the fixed seat assembly 42 to assemble the rotor core 90 and the commutator 92.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
