[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] Reference Figure 1 to Figure 6 , a rotating base of a coreless motor rotor automatic welding device, comprising a mounting platform 35, a guide rail 48, a cylinder 18, a motor 37, a rotating shaft 54, a push rod 56, a carrier positioning block 42 and a material-dispensing device, wherein:

[0036] The guide rail 48 is horizontally mounted on the mounting platform 35, preferably mounted on the mounting platform 35 via a mounting seat 49, and a blocking strip 47 is provided along the length direction of the guide rail 48 to block the carrier 15 for carrying the hollow cup motor rotor that is transported to the guide rail 48 by an external transport mechanism. The carrier 15 is equivalent to a tooling for installing and carrying the hollow cup motor rotor. The external transport mechanism can be a conveyor belt or a manipulator. If it is a conveyor belt, the conveyor belt is perpendicular to the guide rail 48, and the front carrier 15 is transported to the guide rail 48 in a direction perpendicular to the guide rail 48. Since the front carrier 15 is blocked by the blocking strip 47, the rear carriers 15 are lined up on the transport mechanism and wait for the front carrier 15 to be sent away before they can be transported to the guide rail 48 in order.

[0037] The motor 37 and the cylinder 18 are respectively mounted on the mounting platform 35 . The rotating shaft 54 ​​is vertically arranged and rotatably mounted on the mounting platform 35 . The motor 37 is connected to the rotating shaft 54 ​​.

[0038] The carrier positioning block 42 is installed at the top end of the rotating shaft 54, and the carrier positioning block 42 has an inner cavity, and the carrier positioning block 42 includes a top plate 421, a side connecting block 422, and a bottom plate 422 for receiving the carrier 15, the side connecting block 422 connects the top plate 421 and the bottom plate 422, and the bottom plate 422 is provided with a vertical through hole as a moving channel of the top rod. The top plate 421, the side connecting block 422 and the bottom plate 422 are preferably integrally formed.

[0039] The material shifting device includes a material shifting block 23 and a multi-axis motion platform, the material shifting block 23 is installed on the multi-axis motion platform, and a material shifting groove is provided on the material shifting block 23 so as to shift the carrier 15 on the guide rail 48, so that the carrier 15 can extend into the inner cavity of the carrier positioning block 42 and be received by the bottom plate 422 of the carrier positioning block 42, and the carrier 15 can be placed on the bottom plate 422 of the carrier positioning block 42, and preferably the base 44 of the carrier 15 enters the inner cavity of the carrier positioning block 42.

[0040] The carrier 15 has many structural forms, as long as it can carry the hollow cup motor rotor. After the hollow cup motor rotor composed of the coil, the rotor frame and the commutator 45 is placed on the carrier 15, the soldering device 100 above the rotating base can perform welding operations on the hollow cup motor rotor.

[0041] The rotating shaft 54 ​​has a through hole that passes through from top to bottom. The rotating shaft 54 ​​and the push rod 56 are coaxially arranged, and the push rod 56 is movably installed inside the rotating shaft 54, that is, the rotating shaft 54 ​​and the push rod 56 are not fixed together, but are independent of each other, and the two can rotate and move relative to each other. The cylinder 18 is fixedly connected to the lower end of the push rod 56 to drive the push rod 56 to move up and down, so that when the push rod 56 moves upward, the top end of the push rod 56 cooperates with the top plate 421 of the carrier positioning block 42 to clamp the carrier 15, and when the push rod 56 moves downward, it is convenient to release the clamping of the carrier 15. The lower end of the push rod 56 preferably exceeds the lower end of the rotating shaft 54, so that the cylinder 18 is connected to the push rod 56. When the push rod 56 moves upward, the carrier 15 is pressed against the top plate 421, so that the carrier 15 cannot move. In this way, when the rotating shaft 54 ​​drives the carrier positioning block 42 and the carrier 15 to rotate together, the carrier 15 will not shift, thereby not affecting the soldering work of the soldering device 100 above the rotating base on the hollow cup motor rotor.

[0042] Furthermore, the cylinder 18 has a push rod 19, which is connected to the push rod 56 through a push rod connector 57. The push rod 19 is pushed upward to drive the push rod 56 to move upward. The cylinder 18 is fixedly mounted on the mounting platform 35 through a mounting block.

[0043] Furthermore, the top plate 421 is provided with a guide groove 4211, and the guide groove 4211 is parallel to the guide rail 48, so that the carrier 15 moves along the guide groove 4211 to the carrier positioning block 42. If a portion of the carrier 15 extends upward beyond the top plate 421, the guide groove 4211 can well adapt to the shape of the carrier 15, so that the carrier 15 can still enter the inner cavity of the carrier positioning block 42.

[0044] Furthermore, the carrier 15 is provided with two mutually planar first guide surfaces, and correspondingly, the inner wall of the carrier positioning block 42 is also provided with two mutually parallel second guide surfaces, and each of the second guide surfaces is respectively fitted with one of the first guide surfaces. If the carrier 15 and the carrier positioning block 42 have cylindrical structures, the first guide surface and the second guide surface are respectively formed into flat positions, and the two guide surfaces can make the flat positions fit together well, and can also prevent the carrier 15 from having rotational displacement when the carrier positioning block 42 drives the carrier 15 to rotate, thereby affecting the normal welding of the hollow cup motor rotor by the soldering device 100.

[0045] Furthermore, the motor 37 is connected to the rotating shaft 54 ​​through a gear mechanism, and the gear mechanism includes a driving gear 16 and a driven gear 17, and the driving gear 16 and the driven gear 17 are meshed with each other, so the driving gear 16 is installed on the output shaft of the motor 37, and the driven gear 17 is fixedly installed on the rotating shaft 54. The driven gear 17 drives the rotating shaft 54 ​​to rotate, and the rotating shaft 54 ​​drives the carrier positioning block 42 to rotate, and the carrier positioning block 42 drives the carrier 15 to rotate, and the carrier 15 drives the spool 14 on the carrier 15 and the hollow cup motor rotor to rotate. The induction sheet 39 is arranged above the driven gear 17.

[0046] Furthermore, the multi-axis moving platform is an XY-axis moving platform, which is used to drive the material shifting block 23 to move horizontally in a direction parallel to the guide rail and in a direction perpendicular to the guide rail, wherein the X-axis of the XY-axis moving platform is parallel to the guide rail 48, and the Y-axis is perpendicular to the guide rail 48. When the material shifting block 23 moves in a direction perpendicular to the guide rail 48, the material shifting groove can be stuck on the carrier 15. When it moves in a direction parallel to the guide rail 48, the carrier 15 can be moved, so that the carrier 15 can move along the length direction of the guide rail 48 to extend into the inner cavity of the carrier positioning block 42.

[0047] Reference Figure 1 The multi-axis motion platform includes a first cylinder 38, a slider, a mounting frame 22, a second slider 20, and a second cylinder 21. The material-pickup block 23 is fixedly mounted on the mounting frame 22, the mounting frame 22 is fixedly mounted on the first slider 381, the first slider 381 is pushed by the first cylinder 38, the first cylinder 38 pushes the first slider 381 to move forward and backward, the forward and backward movement of the first slider 381 drives the mounting frame 22 fixedly connected to the first slider 381 to move forward and backward, and the forward and backward movement of the mounting frame 22 drives the forward and backward movement of the material-pickup block 23. At the same time, the first cylinder 38 is fixedly mounted on the second slider 20, and the second slider 20 is pushed by the second cylinder 21, and the second cylinder 21 is fixedly mounted on the mounting platform 35. The second cylinder 21 pushes the second slider 20 to move left and right, and the first cylinder 38 fixedly mounted on the second slider 20 moves left and right, and at the same time, drives the material shifting block 23 to move left and right, so that the material shifting block 23 can achieve the functions of moving forward, right, backward, and left, and the carrier 15 carrying the wire cup 14 and the rotor frame that have not yet been welded is moved to the bottom of the solder gun for welding operation.

[0048] Furthermore, the present invention further comprises an encoder, a photoelectric sensor 40 and a sensing sheet 39, wherein the encoder is connected to the output shaft of the motor 37, and the photoelectric sensor 40 and the sensing sheet 39 are respectively mounted on the mounting platform 35 and the rotating shaft 54, so as to obtain the rotation position of the rotating shaft 54. The rotation angle of the rotating shaft 54 ​​can be obtained by the encoder, and the initial position of the rotating shaft 54 ​​can be obtained by the cooperation of the photoelectric sensor 40 and the sensing sheet 39, and the rotation position of the rotating shaft 54 ​​can be obtained by the cooperation of the encoder, the photoelectric sensor 40 and the sensing sheet 39.

[0049] Furthermore, the rotating shaft 54 ​​is mounted on the mounting platform 35 via a bearing, an outer wall of the rotating shaft 54 ​​is provided with an external thread, and a locking nut 53 is connected to the external thread of the rotating shaft 54, thereby locking the rotating shaft 54 ​​on the inner ring of the bearing to prevent axial shaking of the rotating shaft 54 ​​when the rotating shaft 54 ​​rotates. The rotating shaft 54 ​​is mounted on the mounting platform 35 via two bearings, the two bearings are a first bearing 51 and a second bearing 55, the first bearing 51 is above the second bearing 55, and the locking nut 53 locks the rotating shaft 54 ​​on the inner ring of the first bearing 51.

[0050] Furthermore, a receiving hole is provided on the guide rail 48, and the carrier positioning block 42 is located at the receiving hole. Then, the carrier positioning block 42 divides the guide rail 48 into two sections, one section is used to allow the carrier 15 to enter the carrier positioning block 42, and the other section is used to allow the carrier 15 that has completed the welding process to leave the carrier positioning block 42 and move to the next process.

[0051] Furthermore, the plane of the bottom plate 422 for carrying the carrier 15 is coplanar with the plane of the guide rail 48 for carrying the carrier 15 , which facilitates the carrier 15 on the guide rail 48 to enter and exit the carrier positioning block 42 .

[0052] Furthermore, the guide groove 4211 on the top plate 421 is arranged throughout the length, and there are two material shifting grooves on the material shifting block 23, and the two material shifting grooves are arranged along the length direction of the guide rail 48, so as to be used to shift one of the carriers 15 into the carrier positioning block 42 and shift the other carrier 15 out of the carrier positioning block 42 at the same time.

[0053] The base rotating device is integrally arranged below the solder gun of the soldering device 100. The motor 37 is preferably a reduction motor 37 having a gear box 36. The driving gear 16 is fixedly mounted on the output shaft of the gear box 36. The motor 37 is connected to an encoder to form a closed-loop control. The gear box 36 is fixedly mounted on the flange 41 and fixedly mounted on the mounting platform 35 through the flange 41. The rotating shaft 54 ​​is fixedly mounted on the mounting platform 35 through a bearing. A plurality of support columns 34 are respectively arranged around the mounting platform 35 for mounting on the table of the production line.

[0054] A locking nut 53 is arranged above the induction sheet 39, and a bearing and a bearing support ring 50 are arranged at the upper end of the locking nut 53. The bearing and the bearing support ring 50 are arranged inside the bearing mounting seat 52, and the bearing mounting seat 52 is installed on the mounting platform 35. The carrier positioning block 42 is arranged at the upper end of the rotating shaft 54 ​​and is fixedly installed with the rotating shaft 54. The wire cup 14 and the rotor of the hollow cup motor 37 are arranged on the carrier 15 at the same time. The outer side of the rotor shaft 43 of the hollow cup motor 37 is provided with a protective sleeve 13. The protective sleeve 13 is used to protect the commutator 45. In the case of high-temperature welding, the tin beads and rosin will not splash into the slots of the commutator 45 to prevent the generation of defective products.

[0055] The working process of the present invention is as follows:

[0056] The first cylinder 38 pushes the first slider 381 forward, driving the material-dispensing block 23 installed with the first slider 381 to move forward, and the material-dispensing groove on the material-dispensing block 23 is stuck on the carrier 15. Then, the second cylinder 21 pushes the second slider 20 to move rightward, and the movement of the second slider 20 drives the material-dispensing block 23 to move rightward. The material-dispensing block 23 drives the carrier 15 to move rightward under the push of the second cylinder 21. The flat part of the carrier 15 is loaded into the carrier positioning block 42, and at the same time, the cylinder pushes the push rod 19 upward, and the push rod 19 pushes the push rod 56 through the connector 57, so that the push rod 56 moves upward, supports the mold center of the carrier 15, and fixes the carrier 15 between the carrier positioning blocks 42. At the same time, the material-dispensing block 23 retreats backward, moves to the left, and returns to the initial position.

[0057] A pair of soldering guns are first moved downwards. After the soldering guns are powered on, the tin wire sent from the tin breaking machine is melted, and the two wire ends 141 in the wire cup 14 are welded together with the commutator 45 ( Figure 6 The wire ends are upright, and are pressed to a substantially horizontal position by the horizontally moving external pressure head before welding. After welding, a pair of soldering guns of the soldering device 100 above the rotating base are retracted upward.

[0058] The motor 37 drives the driving gear 16 to rotate, and then drives the driven gear 17 meshing with the driving gear 16 to rotate. The rotation of the driven gear 17 drives the rotating shaft 54 ​​fixedly mounted with the driven gear 17 to rotate. The rotation of the rotating shaft 54 ​​drives the induction sheet 39 installed on the rotating shaft 54 ​​to rotate, and at the same time drives the carrier positioning block 42 to rotate. The carrier positioning block 42 drives the carrier 15 to rotate. The rotation angle of the rotating shaft 54 ​​is determined by the induction sheet 39 and the photoelectric sensor 40. Since the position of the thread end 141 is generally odd, when there is only one unwelded thread end 141 left, the solder gun will be on one side next time, so that each thread end 141 of the wire cup 14 is welded to the commutator 45.

[0059] After welding is completed, the push rod 19 falls back, pulling the ejector rod 56 back, and the ejector rod 56 releases the clamping of the carrier 15, so that the material shifting block 23 of the next process can smoothly shift the carrier 15 away from the carrier positioning block 42.

[0060] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
