[0001] This invention relates to the field of magnetic system processing technology, and more specifically to a magnetic system assembly machine. Background Technology

[0002] The magnetic system is an important component installed inside a circuit breaker. For example, patents with publication numbers CN206516586U and CN210092015U disclose that the magnetic system in circuit breakers typically includes a coil assembly, terminals, bolts, and an iron core. The coil assembly includes a coil, a terminal block, and contacts. The coil has two leads, which are welded to the terminal block and contacts respectively. The terminal block passes through the terminals and is fixed with bolts, and the iron core passes through the coil. Patent CN114083281B discloses an automated magnetic assembly device, which is an automated device for welding the two leads of the coil to the terminal block and contacts respectively. However, currently, the assembly of the coil assembly, terminals, bolts, and iron core still requires manual assembly, resulting in low assembly efficiency and an inability to guarantee consistent product quality.

[0032] like Figures 1 to 16 The image shows one embodiment of the present invention:

[0033] A magnetic system assembly machine includes a turntable 1, a stationary plate 2, a turntable drive device and a control system for driving the turntable 1 to rotate. A plurality of magnetic system clamps 3 are arranged on the edge of the turntable 1. The stationary plate 2 is located inside the turntable 1, coaxially arranged with the turntable 1, and positioned above the turntable 1. The turntable 1 can rotate relative to the stationary plate 2. A loading station 4, a core assembly station 5, a terminal assembly station 6, a bolt locking station 7, and a unloading station 8 are sequentially arranged on the outer side of the turntable 1 and the edge of the stationary plate 2. The loading station 4 is used to load coil assemblies onto the magnetic system clamps 3, where a robotic arm grips the coil assemblies. The assembly process is as follows: the iron core assembly station 5 is used to install the iron core into the coil of the coil assembly on the magnetic system fixture 3; the terminal assembly station 6 is used to install the terminal into the terminal block of the coil assembly on the magnetic system fixture 3; the bolt locking station 7 is used to screw the bolt into the terminal to fix the terminal to the terminal block; and the unloading station 8 is used to unload the magnetic system from the magnetic system fixture 3. This achieves automated assembly of the magnetic system. At the same time, multiple magnetic system fixtures work in conjunction with different stations to avoid the stations running idle, greatly improving assembly efficiency and ensuring product quality consistency.

[0034] like Figure 3 As shown, the magnetic system clamp 3 includes a clamp shaft 31 and a clamp base 32. The clamp shaft 31 is rotatably mounted on the turntable 1, with one end on the turntable 1 connected to the clamp base 32, and the other end below the turntable 1 is provided with a first clamp spring. Specifically, the magnetic system clamp 3 also includes a clamp base 35, which is fixed to the turntable 1. A clamp bearing seat 36 is provided between the clamp shaft 31 and the turntable 1. One end of the clamp shaft 31 passes through the clamp base 35 and is connected to the clamp base 32, while the other end is provided with a spring end cap 37. Both ends of the first clamp spring abut against the clamp bearing seat 36 and the spring end cap 37, respectively. The clamp base 35 is provided with a clamp slot 351 for the clamp base 32 to be inserted into. The clamp base 32 has a fixed position that engages with the clamp slot 351 and a rotating position that separates from the clamp slot 351.

[0035] The clamping rotating base 32 is provided with a coil limiting part 321, a contact limiting part 322, and a terminal plate limiting part 323, which can limit the magnetic system. The coil limiting part 321 is provided with a core stop 33 that can be raised and lowered. A second clamping spring is provided between the core stop 33 and the clamping rotating base 32. The core stop 33 has a position to block the extension of the core and a retracted position to avoid misalignment with the core. Specifically, the clamping rotating base 32 is provided with a stop groove for the core stop 33 to be raised and lowered. The second clamping spring is provided in the stop groove. The coil limiting part 321 is also provided with a core limiting block 38. The second clamping spring is used to keep or restore the core stop to the extended position.

[0036] The coil limiting part 321 includes a coil pad, which has an arc-shaped groove that matches the coil. The coil pad can support the coil, protect the coil, and prevent wear between the coil and the fixture swivel 32.

[0037] The terminal block limiting part 323 is provided with a terminal top straightening block 34 that can be raised and lowered. A third clamping spring is provided between the terminal top straightening block 34 and the clamping rotating seat 32. The terminal top straightening block 34 has an installation position that is retracted into the clamping rotating seat 32 and a top straightening position that extends out of the clamping rotating seat 32. Specifically, the clamping rotating seat 32 is provided with a top straightening groove for raising and lowering the terminal top straightening block 34. The third clamping spring is provided in the top straightening groove. The third clamping spring is used to keep or restore the top straightening position of the terminal top straightening block 34. The terminal top straightening block 34 is provided with a top straightening inclined surface on the side facing the terminal block. When the terminal top straightening block 34 is raised, the top straightening inclined surface can straighten the tilted terminal.

[0038] The terminal block limiting part 323 is also provided with a terminal guide block 324 and a terminal stop block 325. The terminal guide block 324 and the terminal stop block 325 are arranged in the same straight line. The terminal guide block 324 is provided with a guide slope 326. The inclination angle of the guide slope 326 is consistent with the inclination angle required when assembling the terminal block. The clamping base 32 is provided with rotating clamping grooves 327 on both sides.

[0039] The magnetic system fixture 3 can be linked with some structures in each workstation to realize the automated assembly of the magnetic system.

[0040] The iron core assembly station 5 includes an iron core vibratory plate 51, an iron core linear vibratory track 52, an iron core misalignment mechanism 53, an iron core feeding mechanism 54, and an iron core loading and pressing mechanism 55. The iron core linear vibratory track 52 is connected to the iron core vibratory plate 51. The iron core misalignment mechanism 53 is located at the end of the iron core linear vibratory track 52. An iron core loading detector 521 connected to the control system is provided on one side of the iron core linear vibratory track 52. The iron core loading detector 521 can be a photoelectric switch sensor to ensure that the iron core linear vibratory track 52 does not break or jam.

[0041] The core misalignment mechanism 53 is used to misalign the cores one by one by moving up and down; specifically, the core misalignment mechanism 53 includes a core misalignment plate 531, a core misalignment cylinder 532 disposed on the core misalignment plate 531, and a core misalignment block 533 disposed on the core misalignment cylinder 532, wherein the core misalignment block 533 is provided with a core groove 534 adapted to the core.

[0042] It also includes a core positioning detector installed in the corresponding core slot 534. The core positioning detector is connected to the control system and is used to detect whether there is a core in the core slot 534.

[0043] The iron core feeding mechanism 54 is used to magnetically attract and load the misaligned iron core into the coil. Specifically, the iron core feeding mechanism 54 includes an iron core feeding frame 541, an iron core feeding movable seat 542 that is laterally slidably arranged on the iron core feeding frame 541, and an iron core feeding slide plate 543 that is laterally slidably arranged on the iron core feeding movable seat 542. An iron core suction rod 544 and an iron core feeding cylinder 545 that drives the iron core suction rod 544 to move are slidably arranged on the iron core feeding slide plate 543. Its lateral sliding arrangement adopts a slide rail and slider structure.

[0044] The core misalignment cylinder 532 drives the core misalignment block 533 to rise and fall, so that it has a feeding position where the core groove 534 is connected to the core linear vibration track 52 and a discharging position where the core groove 534 is aligned with the core suction rod 544.

[0045] The core loading and pressing mechanism 55 is used to position the core stop 33 in the retracted position and press the coil before the core is loaded into the core feeding mechanism 54. Specifically, the core loading and pressing mechanism 55 includes a core loading and pressing frame 551 disposed on the stationary plate 2 and a core loading and pressing slide plate 552 vertically slidably disposed on the core loading and pressing frame 551. A coil assembly pressing plate 553 is disposed on the core loading and pressing slide plate 552, and a core installation pressing rod 554 that is linked and cooperates with the core stop 33 is disposed on the core loading and pressing slide plate 552. The coil assembly pressing plate 553 can press the coil assembly to facilitate the installation of the core. In this embodiment, the core includes a body and a circular flange disposed at one end of the body. A clearance notch is provided on one side of the circular flange. The circular flange abuts against the core stop 33 to prevent the core from being pulled out of the coil when the core suction rod 544 retracts.

[0046] The iron core loading and pressing frame 551 is equipped with an iron core installation detector 555 connected to the control system. It uses a photoelectric switch sensor to detect whether the iron core is installed in place.

[0047] The main working process of the iron core assembly station 5 is as follows: the iron core vibratory plate 51 feeds the iron core into the iron core slot 534 through the iron core straight vibration track 52. The iron core misalignment cylinder 532 drives the iron core misalignment block 533 to rise to the discharge position. The iron core suction rod 544 first moves towards the iron core slot 534 to pick up the iron core inside, and then moves back to let the iron core misalignment block 533 fall back to the feeding position. After that, the iron core suction rod 544 moves towards the coil in the magnetic system fixture 3. At this time, the coil assembly pressure plate 553 descends to press the coil assembly. At the same time, the iron core installation pressure rod 554 presses the iron core stop block 33 down to the retracted position. When the iron core suction rod 544 puts the iron core into the coil, the iron core installation pressure rod 554 rises. The iron core stop block 33 returns to the extended position under the action of the second fixture spring, which can prevent the iron core from falling off the coil when the iron core suction rod 544 moves back.

[0048] like Figure 5 As shown, the terminal assembly station 6 includes a terminal vibratory feeder 61, a terminal feed channel 62, a terminal distribution mechanism 63, a terminal clamping mechanism 64, and a terminal loading and pressing mechanism 65. The two ends of the terminal feed channel 62 are connected to the terminal vibratory feeder 61 and the terminal distribution mechanism 63, respectively. The terminal feed channel 62 is equipped with a terminal loading detector 621 connected to the control system. It uses a photoelectric switch sensor to detect whether a terminal is passing through the terminal feed channel 62, so as to avoid material breakage or jamming.

[0049] The terminal distribution mechanism 63 is used to distribute the terminals conveyed from the terminal material channel 62. Specifically, the terminal distribution mechanism 63 includes a terminal distribution seat 631, on which a terminal channel 632 is provided. At the end of the terminal channel 632, a gripping part that cooperates with the terminal gripping mechanism 64 is provided. At one end of the terminal channel 632, a terminal top block assembly 633 is provided, and at the other end, a terminal stop block assembly 634 is provided. The terminal stop block assembly 634 is located close to the gripping part. The terminal distribution seat 631 is provided with a terminal position detector connected to the control system, which adopts a photoelectric switch sensor for detecting the position of the terminals in the gripping part.

[0050] The terminal top block assembly 633 includes a terminal top block slidably disposed in the terminal channel 632 and a first terminal cylinder for driving the terminal top block to move. The terminal stop block assembly 634 includes a terminal positioning stop block disposed at the end of the gripping part and a second terminal cylinder for driving the terminal positioning stop block to move.

[0051] The terminal gripper mechanism 64 is used to grip the terminals one by one, rotate them at a certain angle, and insert them into the terminal block. Specifically, the terminal gripper mechanism 64 includes a terminal movable seat 641 and a rotating gripper 642 disposed on the terminal movable seat 641. The terminal movable seat 641 can achieve bidirectional movement in the horizontal plane through multiple sets of cylinders, sliders, and slide rail structures. Since the end dimension of the terminal mounting part of the terminal block is larger than the inner width of the terminal, the terminal needs to be tilted at a certain angle to be installed into the terminal block. Therefore, the rotating gripper 642 is used.

[0052] like Figure 6 As shown, the terminal loading and straightening mechanism 65 is used to position the terminal top straightening block 34 in the installation position before the terminal clamping mechanism 64 inserts the terminal. Specifically, the terminal loading and straightening mechanism 65 includes a terminal loading and straightening frame 651 disposed on the stationary plate 2 and a terminal loading and straightening slide plate 652 vertically slidably disposed on the terminal loading and straightening frame 651. A coil assembly pressure plate is disposed on the terminal loading and straightening slide plate 652. A terminal straightening cylinder 653 and a terminal straightening push rod 654 connected to the terminal straightening cylinder 653 are disposed on one side of the terminal loading and straightening frame 651. The terminal straightening push rod 654 is linked with the terminal top straightening block 34. A terminal installation detector 655 connected to the control system is disposed on the terminal loading and straightening slide plate 652. The detector uses a photoelectric switch sensor to detect whether the terminal is installed in place.

[0053] The main working process of the terminal assembly station 6 is as follows: The terminal vibratory feeder 61 transports the terminal to the terminal channel 632 of the terminal distribution seat 631 through the terminal material channel 62. The terminal top block assembly 633 pushes the terminal to the gripping part. Usually, multiple terminals are placed in the terminal channel 632 at one time to avoid individual terminals tipping over. The terminal stop block assembly 634 stops the terminal at the gripping part. The rotating gripper 642 grips the terminal and rotates it at a certain angle to install it into the terminal plate. At this time, the coil assembly pressure plate descends to press the coil assembly. At the same time, the terminal pressing top rod 654 presses the terminal top block 34 down to the installation position. After the terminal is installed into the terminal plate, the terminal top block 34 rises. Under the action of the third clamp spring, the terminal top block 34 returns to the top position, which can just right the tilted terminal.

[0054] It also includes a testing station 9 located between the loading station 4 and the core assembly station 5. The testing station 9 includes a coil assembly detector connected to the control system and uses a photoelectric switch sensor to detect whether there is a coil assembly on the magnetic system fixture 3 passing through the testing station 9.

[0055] like Figure 7 and Figure 8As shown, it also includes a first clamping rotation station 10 disposed between the terminal assembly station 6 and the bolt locking station 7. The first clamping rotation station 10 is used to rotate the clamping turntable 32 so that the bolt locking station 7 aligns with the threaded hole of the terminal. Specifically, the first clamping rotation station 10 includes a clamping pressing mechanism 101, a terminal straightening mechanism 102 and a clamping rotation mechanism 103. The clamping pressing mechanism 101 is disposed below the turntable, the terminal straightening mechanism 102 is disposed outside the turntable 1, and the clamping rotation mechanism 103 is disposed on the stationary plate 2.

[0056] The clamp pressing mechanism 101 includes a clamp pressing cylinder 104 and a clamp pressing block 105 connected to the clamp pressing cylinder 104. The clamp pressing block 105 is located below the spring end cap 37.

[0057] The terminal correction mechanism 102 includes a terminal correction frame 106, a terminal correction cylinder 107 disposed on the terminal correction frame 106, and a terminal correction top block 108 connected to the terminal correction cylinder 107.

[0058] like Figure 8 As shown, the clamp rotation mechanism 103 includes a clamp rotation frame 109 and a clamp rotation gripper 110 vertically slidably disposed on the clamp rotation frame 109. The clamp rotation gripper 110 includes a gearbox 111, a rotating gear shaft 112 rotatably disposed in the gearbox 111, a drive cylinder 113 disposed outside the gearbox 111, a rotating rack 114 connected to the drive cylinder 113, and a rotating block 115 connected to one end of the rotating gear shaft 112. The rotating block 115 is provided with a rotating clamping rod 116 adapted to the rotating clamping groove 327. The rotating rack 114 meshes with the rotating gear shaft 112.

[0059] The main working process of the first fixture rotation station 10 is as follows: the terminal correction cylinder 107 drives the terminal correction top block 108 to correct the wiring terminal. Then, the fixture pressing cylinder 104 drives the fixture pressing block 105 to push the spring end cover 37 up, so that the fixture rotating seat 32 is in a rotating position separated from the fixture slot 351. Then, the rotating clamping rod 116 extends into the rotating clamping slot 327, and the driving cylinder 113 drives the rotating rack 114 to translate and drive the rotating gear shaft 112 to rotate, so that the fixture rotating seat 32 rotates at a certain angle so that the locking bolt station 7 aligns with the threaded hole of the wiring terminal.

[0060] like Figures 9 to 12As shown, the bolt locking station 7 includes a bolt vibrating plate 71, a bolt linear vibrating track 72, a bolt distribution mechanism 73, a bolt conveying hose, a bolt locking mechanism 74, and a bolt locking and straightening mechanism 75. The bolt linear vibrating track 72 is connected to the bolt vibrating plate 71 and the bolt distribution mechanism 73 at both ends, and the bolt conveying hose is connected to the bolt distribution mechanism 73 and the bolt locking mechanism 74 at both ends. The bolt locking and straightening mechanism 75 is mounted on the stationary plate 2. A bolt feeding detector 76 connected to the control system is mounted on the bolt linear vibrating track 72. A photoelectric switch sensor is used to detect whether a bolt passes through the bolt linear vibrating track 72 to prevent material breakage or jamming.

[0061] The bolt distribution mechanism 73 is used to distribute bolts one by one. Specifically, the bolt distribution mechanism 73 includes a bolt distribution seat 731, a bolt slider 732, a bolt receiving block 733, and a bolt distribution cylinder 734. The bolt distribution seat 731 has a bolt sliding cavity 7311 arranged horizontally inside. The bolt slider 732 is slidably disposed in the bolt sliding cavity 7311. The bolt distribution cylinder 734 drives the bolt slider 732 to move within the bolt sliding cavity 7311.

[0062] The bolt distribution seat 731 is provided with a bolt inlet 735 at the end of the bolt linear vibration track 72. A bolt outlet joint 736 is provided at the lower end of the bolt distribution seat 731. The bolt slider 732 includes a channel portion, a stop portion, and a groove portion. The channel portion and the groove portion are connected. The groove portion is perpendicular to the moving direction of the bolt slider. The bolt receiving block 733 is slidably disposed within the groove portion. A guide groove 737 is provided on the bolt distribution seat 731, and a bolt receiving block 733 is slidably disposed within the guide groove 737. A guide pin 738 is provided, and a sliding hole is provided in the sliding groove. The sliding hole is an oblong hole. The bolt receiving block 733 is provided with a through hole for the guide pin 738 to pass through. The guide pin 738 is located in the sliding hole. The bolt receiving block 733 is provided with a bolt slot 739 at the end facing the bolt inlet 735. A bolt positioning detector 77 connected to the control system is provided above the bolt inlet 735. It adopts a photoelectric switch sensor to detect whether the bolt in the bolt distribution seat 731 is in position.

[0063] The bolt locking mechanism 74 includes a bolt locking servo motor 741 with settable torque and a bolt bit 742. The bolt locking servo motor 741 drives the bolt bit 742 to first reverse a certain angle so that the bolt is aligned with the threaded hole of the terminal, and then rotates forward and tightens the bolt with a certain torque. Specifically, the bolt locking mechanism 74 includes a bolt locking frame 743 and a first bolt slide plate 744 and a second bolt slide plate 745 slidably disposed on the bolt locking frame 743. The first bolt slide plate 744 is provided with a chuck fixing plate 746, and the chuck fixing plate 746 is provided with a bolt chuck 7461. The bolt locking servo motor 741 drives the bolt bit 742 to first reverse a certain angle so that the bolt is aligned with the threaded hole of the terminal, and then rotates forward and tightens the bolt with a certain torque. The servo motor 741 is mounted on the second bolt slide plate 745. The bolt locking servo motor 741 is connected to the bolt bit 742. The bolt bit 742 passes through the chuck fixing plate 746 and extends into the bolt chuck 7461. The bolt chuck 7461 includes a first bolt channel 747 aligned with the bolt bit 742 and a second bolt channel 748 connected to the bolt delivery hose. The second bolt channel 748 is inclined relative to the first bolt channel 747. The bolt chuck 7461 also includes bolt clamping plates 749 hinged to its two sides. The two bolt clamping plates 749 can clamp the bolt, improving the accuracy of locking the bolt.

[0064] like Figure 12 As shown, the bolt clamping mechanism 75 is used to clamp the terminal block when the bolt clamping mechanism 74 clamps the bolt. Specifically, the bolt clamping mechanism 75 includes a bolt clamping frame 751 and a bolt clamping slide plate 752 vertically slidably disposed on the bolt clamping frame 751. The bolt clamping slide plate 752 is provided with a first clamping block 753 adapted to the coil assembly and a second clamping block 754 adapted to the terminal block. An auxiliary clamping block 755 is provided on the side of the first clamping block 753 away from the bolt clamping slide plate 752. A ball-head plunger is provided on the side of the second clamping block 754 facing the terminal block, which can better clamp the terminal block and improve the success rate of bolt clamping.

[0065] The bolt clamping frame 751 is equipped with a first bolt clamping detector 756 and a second bolt clamping detector 757 on one side. Both of them are photoelectric switch sensors. The first bolt clamping detector 756 detects whether there is a bolt, that is, whether the bolt is in place. The second bolt clamping detector 757 detects whether the bolt is stuck, that is, whether the bolt clamping is successful, thus improving the success rate of bolt clamping.

[0066] The main working process of the bolt fastening station 7 is as follows: the bolt vibrating plate 71 feeds the bolt to the bolt straight vibration track 72, which conveys the bolt from the bolt feed port 735 to the bolt slot 739 of the bolt receiving block 733. The bolt dispensing cylinder 734 drives the bolt slider 732 to move, so that the channel part of the bolt slider 732 is aligned with the bolt discharge joint 736. At the same time, with the cooperation of the guide groove 737, the guide pin 738 and the sliding hole, the bolt receiving block 733 moves backward, allowing the bolt to fall into the bolt discharge joint 736. At the same time, the stop part of the bolt slider 732 also blocks the bolt. The bolt is fed from the outlet of the bolt linear vibrating track 72, and then the bolt is conveyed by the bolt conveying hose to the second bolt channel 748, and then slides into the first bolt channel 747.
