[0019] Example Reference Figures 1 to 16This embodiment provides a circular production line for motors, specifically including: a workbench 1, with a circular transport line 2 on top of the workbench 1; a riveting body feeding belt 3 for providing riveting bodies 50 and a coil feeding belt 4 for providing coils 60 on one side of the circular transport line 2; at least two limiting grooves 5001 are provided at the bottom of the riveting body 50; multiple insert rods 5002 are provided at the top of the riveting body 50; and a threaded hole 5003 is provided on one side of the riveting body 50; a carrier 5, including a sliding seat 501, which is connected to the circular transport line 2 and moves along the circular transport line 2. A support base 502 is provided on the top of the seat 501. The support base 502 is connected to a tilting table 503. A bearing guide rail 504 is provided along the length of the tilting table 503. A first bearing plate 505 and a second bearing plate 506 are slidably provided on the top of the bearing guide rail 504. The first bearing plate 505 and the second bearing plate 506 are used to support the riveted body 50. A first limiting part 507 and a second limiting part 508 are respectively provided on the top of the first bearing plate 505 and the second bearing plate 506. The first limiting part 507 and the second limiting part 508 are respectively located in two limiting grooves 5001. The carrier 5 has a lock. The worktable 5 has two states: locked and unlocked. In the locked state, the first support plate 505 and the second support plate 506 are close to each other, so that the first limiting part 507 and the second limiting part 508 clamp the bottom of the riveted body 50. In the unlocked state, the first support plate 505 and the second support plate 506 are far apart, so that the first limiting part 507 and the second limiting part 508 release the riveted body 50. The unlocking module 6 is located at the top of the worktable 1 and is used to switch the state of the carrier 5. The riveted body feeding module 7 is used to grab the riveted body 50 and place it on the carrier 5. The coil feeding module 8 is located downstream of the riveted body feeding module 7 and is used to... The device includes a coil gripping module 60 and a mounting module 5002; a nut loading module 9, located downstream of the coil loading module 8, for providing the nut 70 and mounting it onto the threaded hole 5003; a flipping module 10, located downstream of the nut loading module 9, for rotating the flipping table 503 relative to the support base 502 so that the end of the nut 70 faces upward; a PCB board loading module 11, located downstream of the flipping module 10, for providing the PCB board 80 and mounting it onto the top of the nut 70; and a unloading mechanism 12 for removing the finished motor from the carrier 5.

[0020] A circular transport line 2 is set on the top of the workbench 1, and the sliding seat 501 of the carrier 5 is connected to the circular transport line 2 to realize cyclic transport. A riveting body feeding belt 3, a coil feeding belt 4, a nut feeding module 9, and a PCB board feeding module 11 are set along the circular transport line 2 to provide the riveting body 50, coil 60, nut 70, and PCB board 80, respectively. The unlocking module 6 switches the carrier 5 to the unlocked state. The riveting body feeding module 7 places the riveting body 50 on the top of the first support plate 505 and the second support plate 506, and makes the first limiting part 507 and the second limiting part 508 respectively located in the corresponding limiting groove 5001. The first support plate 505 The first limiting part 507 and the second limiting part 508 clamp and fix the riveting body 50. The coil feeding module 8 puts the coil 60 onto the insertion rod 5002. The nut feeding module 9 installs the nut 70 in the threaded hole 5003. The flipping module 10 drives the flipping table 503 to rotate relative to the support seat 502 so that the end of the nut 70 faces upward, which is convenient for the PCB board feeding module 11 to install the PCB board 80. The unloading mechanism 12 takes out the finished motor. The carrier 5 continues to cycle, thereby completing the assembly of the motor. The whole process does not require manual intervention, which improves the production capacity, and the product consistency and yield are high.

[0021] The tilting table 503 is provided with at least two transmission guide rails 509 along its width direction. A transmission plate 510 is slidably provided on the top of each of the two transmission guide rails 509. A strip groove 511 is opened on the top of the transmission plate 510 at an angle relative to the length direction of the transmission guide rail 509. A sliding member 512 is provided in the strip groove 511. The tops of the two sliding members 512 are fixedly connected to the first bearing plate 505 and the second bearing plate 506, respectively. The two transmission plates 510 are connected by a connecting rod 513. A movable rod 514 is fixedly connected to one side of the connecting rod 513. A sleeve 515 is slidably sleeved on one end of the movable rod 514. The sleeve 515 is fixedly connected to the tilting table 503 by a connecting block 516. A first elastic reset member is sleeved on the movable rod 514. The two ends of the first elastic reset member are in contact with the connecting rod 513 and the sleeve 515, respectively.

[0022] The unlocking module 6 includes an unlocking cylinder 601, and an unlocking push plate 602 is connected to the output end of the unlocking cylinder 601. The unlocking push plate 602 is located on one side of the connecting rod 513 and is used to push the connecting rod 513.

[0023] By unlocking the push plate 602, the connecting rod 513 is pushed. The two ends of the connecting rod 513 are respectively connected to two transmission plates 510. The transmission plates 510 slide along the corresponding transmission guide rails 509. The strip groove 511 on the top of the transmission plate 510 slides relative to the sliding member 512, thereby causing the sliding member 512 to move along the length direction of the bearing guide rail 504. The two transmission plates 510 are symmetrically arranged, and the top strip grooves 511 are also symmetrically arranged, thereby causing the first bearing plate 505 and the second bearing plate 506 to move towards each other or away from each other at the same time, thus realizing the locking or unlocking of the riveted body 50. The locking and unlocking methods are convenient and stable, improving work efficiency.

[0024] The tilting table 503 has a rotating shaft 517 connected to both sides. The rotating shaft 517 is hinged to the support base 502. The part of the rotating shaft 517 located on the outside of the support base 502 is connected to a cam 518 and a long handle 519. A positioning assembly is provided below the cam 518. The positioning assembly includes a positioning block 520, a positioning wheel 521 and a second elastic reset member. The positioning block 520 has a hinge hole 5201. The positioning block 520 is hinged to the outer wall of the support base 502 through the hinge hole 5201. The top of the positioning wheel 521 contacts the bottom of the cam 518. The second elastic reset member is located below the positioning block 520 and its two ends are connected to the bottom of the positioning block 520 and the support base 502, respectively.

[0025] The flipping module 10 includes a flipping cylinder 1001, and a flipping push plate 1002 is connected to the output end of the flipping cylinder 1001. The flipping push plate 1002 is located on one side of the long handle 519 and is used to push the long handle 519.

[0026] like Figure 13 As shown, the second elastic reset element is a spring. The spring is located below the end of the positioning block 520 away from the hinge hole 5201. The top end of the spring is fixedly connected to the bottom surface of the positioning block 520, and the bottom end of the spring is fixedly connected to the support base 502. A connecting shaft passes through the hinge hole 5201 and is fixedly connected to the outer wall of the support base 502. The positioning block 520 is rotatably connected to the connecting shaft. The hinge hole 5201 serves as the rotation center of the positioning block 520. The spring is initially in a compressed state, applying an upward force to the positioning block 520, causing the positioning wheel 521 to abut against the cam 518, thereby fixing the tilting table 503. Figure 14As shown, the long handle 519 is pushed from one side by the flipping push plate 1002, causing the cam 518 to rotate. Utilizing the shape characteristics of the outer contour of the cam 518, the lower surface of the cam 518 presses downward against the positioning wheel 521, causing the positioning wheel 521 and the positioning block 520 to rotate downward along the rotation center. The spring undergoes adaptive deformation and further compression. When the tilting table 503 rotates 90 degrees, the positioning block 520, the positioning wheel 521, and the spring return to their original positions, re-fixing the tilting table 503. By connecting the long handle 519 and the cam 518 on the rotating shaft 517, and setting the positioning component below the cam 518, the rotation and fixing of the tilting table 503 are convenient and the rotation angle is precise.

[0027] The flip reset module 18 has the same structure as the flip module 10. By pushing the long handle 519 from the other side through the flip reset module 18, the rotation reset of the flip table 503 is realized.

[0028] The riveting body feeding module 7 includes a first linear mechanism 701, which is connected to a first cylinder 702. The output end of the first cylinder 702 is connected to a second cylinder 703, and the output end of the second cylinder 703 is connected to a magnet 704. The magnet 704 is used to attract the riveting body 50. Side rods 705 are connected to both sides of the second cylinder 703. A blocking block 706 is provided at the bottom of the side rod 705, and the blocking block 706 is in contact with the top of the riveting body 50.

[0029] The blocking block 706 at the bottom of the side rod 705 presses down on the top of the riveted body 50 to achieve positioning and prevent relative displacement when the magnet 704 attracts the riveted body 50. After the riveted body 50 is placed in the carrier 5, the first cylinder 702 remains stationary, and the output end of the second cylinder 703 retracts, thereby causing the magnet 704 to detach from the riveted body 50. By controlling the stroke of the blocking block 706 and the magnet 704 by two independent cylinders respectively, the riveted body 50 is transferred with accurate positioning and high transfer efficiency.

[0030] The coil feeding module 8 includes a second linear mechanism 801, which is connected to a third cylinder 802. The output end of the third cylinder 802 is connected to a base 803. A head 804 is slidably disposed on the inner wall of the base 803 in the vertical direction for embedding the coil 60. A ball-head plunger 805 is disposed on the side of the head 804 for pressing against the inner wall of the coil 60. A top plate 806 is fixedly connected above the base 803. A slide rod 807 is connected to the top of the head 804. The slide rod 807 passes through the base 803 and the top plate 806 and is slidably connected to the base 803 and the top plate 806. A third elastic reset member is sleeved on the slide rod 807.

[0031] By setting a ball-head plunger 805 on the side of the insert 804, the coil 60 is locked by utilizing the elasticity and other properties of the ball-head plunger 805. After the coil 60 is inserted into the insert rod 5002, the insert rod 5002 is used to push the insert 804 upward and disengage it from the coil 60. The insert 804 is reset in conjunction with the slide rod 807 and the third elastic reset component. The steps of gripping, locking, placing and unlocking the coil 60 are highly sequential, which improves the transfer efficiency.

[0032] The circular transport line 2 includes a first transport line 201, a first ferry module 202, a second transport line 203, and a second ferry module 204 connected end to end in sequence. Both the first ferry module 202 and the second ferry module 204 include a ferry plate 241. The ferry plate 241 is connected to the end of the first transport line 201 or the end of the second transport line 203. A ferry linear mechanism 242 is connected to the bottom of the ferry plate 241.

[0033] The first transport line 201 and the second transport line 203 are arranged in parallel, and both the first transport line 201 and the second transport line 203 are equipped with transport guide rails, such as Figure 4 As shown, the ferry plate 241 in the first ferry module 202 and the second ferry module 204 is also equipped with a transport guide rail. The ferry plate 241 is moved by the ferry linear mechanism 242, so that the transport guide rail on the ferry plate 241 is connected with the transport guide rail on the first transport line 201 or the second transport line 203, thereby realizing the circular transport of the vehicle 5.

[0034] A riveting body size detection module 13 is provided between the riveting body feeding module 7 and the coil feeding module 8 to detect the thickness of the riveting body 50. A coil pressing module 14 and a wire cutting module 15 are provided between the coil feeding module 8 and the nut feeding module 9. The coil pressing module 14 is used to press the coil 60, and the wire cutting module 15 is used to trim the wire ends of the coil 60. A screw-driving module 16, a soldering module 17, a flip-reset module 18, a trimming module 19, and a finished product inspection module 20 are provided between the PCB board feeding module 11 and the unloading mechanism 12. The screw-driving module 16 is used to lock the PCB board 80 to the nut 70. The soldering module 17 is used to solder the wire ends of the coil 60 to the PCB board 80. The flip-reset module 18 is used to drive the flip table 503 to rotate and reset. The trimming module 19 is used to trim the solder joints. The finished product inspection module 20 is used to inspect the finished motor.

[0035] The thickness of the riveted body 50 refers to the dimension of the riveted body 50 along the length of the insert rod 5002. The riveted body dimension detection module 13, coil pressing module 14, wire cutting module 15, screw driving module 16, soldering module 17, trimming module 19, and finished product detection module 20 are all commonly used mechanisms in this field, and their working principles will not be described in detail in this manual.

[0036] The feeding mechanism 12 includes an OK feeding module 1201, an NG feeding module 1202, an OK temporary storage belt 1203, and an NG temporary storage belt 1204.

[0037] Production line workflow: Sufficient materials are placed on the riveting body feeding belt 3, coil feeding belt 4, nut feeding module 9, and PCB board feeding module 11 respectively. Soldering module 17 prepares solder wire and the soldering iron reaches the specified temperature.

[0038] Carrier 5 arrives at riveting body loading module 7, such as Figures 5 to 7 As shown, the unlocking push plate 602 pushes the connecting rod 513, causing the transmission plate 510 to move along the transmission guide rail 509. Simultaneously, the movable rod 514 slides along the inner wall of the sleeve 515, compressing the first elastic reset member. Under the action of the strip groove 511 and the sliding member 512, the first bearing plate 505 and the second bearing plate 506 move away from each other, and the carrier 5 switches to the unlocked state. Figure 10 As shown, the first linear mechanism 701 and the first cylinder 702 in the riveting body feeding module 7 drive the blocking block 706 to move and adhere to the top surface of the riveting body 50. The output end of the second cylinder 703 extends downward, causing the magnet 704 to be attracted to the top surface of the riveting body 50, thereby placing the riveting body 50 in the carrier 5. At this time, the unlocking push plate 602 retracts, and under the action of the first elastic reset member, the transmission plate 510, the connecting rod 513, and the movable rod 514 are reset, thereby causing the first limiting part 507 and the second limiting part 508 to clamp the bottom of the riveting body 50. The carrier 5 switches to the locked state, and the carrier 5 enters the next work station.

[0039] The carrier 5 arrives at the riveted body size detection module 13, which detects the thickness of the riveted body 50. If the size is qualified, it proceeds to the next work station.

[0040] Carrier 5 arrives at coil loading module 8, such as Figure 11 and Figure 12 As shown, the second linear mechanism 801 and the third cylinder 802 drive the insert 804 to be inserted into the coil 60. The ball plunger 805 presses against the inner wall of the coil 60, moving the coil 60 above the insertion rod 5002 of the riveting body 50. The output end of the third cylinder 802 extends downward, and the coil 60 is fitted into the insertion rod 5002. The insertion rod 5002 pushes the insert 804 upward to push the coil 60 out. At the same time, the slide rod 807 slides upward along the top plate 806, the third elastic reset member is compressed, and the output end of the third cylinder 802 retracts upward. The coil 60 remains in the insertion rod 5002. Under the action of the third elastic reset member, the insert 804 and the slide rod 807 are reset, completing the installation of a single coil 60. After the riveting body 50 is filled with coils 60, the carrier 5 enters the next work station.

[0041] The carrier 5 arrives at the coil pressing module 14, presses the coil 60 completely onto the riveting body 50, and checks the height dimension. If the dimension is qualified, the carrier 5 moves to the next work station.

[0042] The vehicle 5 arrives at the wire cutting module 15 and cuts off the excess part of the coil 60 wire, leaving only the length that is convenient for welding later.

[0043] The carrier 5 arrives at the nut loading module 9, grabs the nut 70, aligns it with the threaded hole 5003, and screws the nut 70 into the riveting body 50.

[0044] The carrier 5 enters the flipping module 10 and flips the flipping table 503 90 degrees so that the end of the nut part 70 faces upward, which is convenient for subsequent operations.

[0045] The carrier 5 enters the PCB board loading module 11. The PCB board loading module 11 has a cylinder group 1101 and a suction cup 1102. The suction cup 1102 adsorbs the PCB board 80. The cylinder group 1101 drives the suction cup 1102 to attach the PCB board 80 to the top of the riveting body 50, the coil 60, and the nut 70. The screw-driving module 16 locks the PCB board 80 onto the nut 70.

[0046] The first transfer module 202 transfers the carrier 5 from the first transport line 201 to the second transport line 203, and the soldering module 17 solders the wire ends of the coil 60 to the corresponding pads on the PCB board 80.

[0047] The carrier 5 enters the flip-and-reset module 18, which flips the flip table 503 90 degrees in the opposite direction to reset it, and the trimming module 19 trims the solder joints.

[0048] The carrier 5 enters the finished product inspection module 20, and tests the motor parameters through a professional motor testing instrument, giving an OK / NG signal. Based on the OK / NG signal issued by the motor testing instrument, the carrier 5 is stopped at the OK unloading module 1201 or the NG unloading module 1202. Both the OK unloading module 1201 and the NG unloading module 1202 are equipped with an unlocking module 6 on one side. The structure of the OK unloading module 1201 and the NG unloading module 1202 is the same as that of the riveting body loading module 7. The OK unloading module 1201 and the NG unloading module 1202 respectively grab the finished motor and put it into the OK temporary storage belt 1203 or the NG temporary storage belt 1204.

[0049] After the finished motor is removed, the second transfer module 204 transfers the empty carrier 5 from the second transport line 203 to the first transport line 201, thereby realizing return and circulation.
