Description

Technical Field

[0001] This application relates to the field of brushed motor technology, and in particular to a commutator mounting device. Background Technology

[0002] The commutator in an electric motor is a crucial component, responsible for the periodic change in current direction during motor operation, thereby driving the motor's normal operation. The installation of the commutator in a motor involves a precise positioning and fixing process to ensure its stability and reliability during high-speed operation.

[0003] In the past, the installation of motor commutators typically relied on manual operation and experience-based judgment. This method was not only inefficient but also susceptible to human error, leading to inconsistent installation quality. With the continuous development and advancement of motor technology, the requirements for commutator installation accuracy have become increasingly stringent.

Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0060] See Figure 1 as well as Figure 2 As shown, this application provides a commutator installation device. The commutator installation device includes a frame 1, a turntable assembly 2 rotatably mounted on the frame 1, and a rotor loading device 3, a detection and flipping device 4, a commutator assembly device 5, a rotor unloading device 6, and a circulating material collection device 7 sequentially arranged around the turntable assembly 2 on the frame 1. The turntable assembly 2 includes a turntable body 21 and a plurality of templates 22 arranged around the turntable body 21 for magnetically attracting the rotor. Rotation of the turntable assembly 2 can drive the templates 22 to sequentially engage with the rotor loading device 3, the detection and flipping device 4, the commutator assembly device 5, and the rotor unloading device 6. The circulating material collection device 7 is arranged to engage with the rotor unloading device 6 for the cyclical transport of the fixture.

[0061] The technical solution of this application allows the rotor feeding device 3 to feed the material onto the template 22, and then move along with the turntable body 21 to the corresponding workstation of each device. Each device and the template 22 cooperate to realize the assembly operation of the commutator. The degree of automation is high, and the commutator can be installed efficiently and accurately.

[0062] See Figure 8As shown, in some embodiments, the rotor feeding device 3 includes a rotor feeding conveyor line 31 and a rotor feeding gripping module 32; the rotor feeding conveyor line 31 includes two parallel and synchronously conveying conveyor belts 311, and a guide limiting mechanism 312 is provided along the conveying direction of the two conveyor belts 311. The rotor is supported between the two conveyor belts 311 and is conveyed along the guide limiting mechanism 312; the rotor feeding gripping module 32 is docked between the rotor feeding conveyor line 31 and the template 22, and is used to grip and transfer the rotor on the rotor feeding conveyor line 31 to the template 22.

[0063] In this embodiment, the rotor loading conveyor line 31 is connected to a previous processing device, such as a rotor loading device. The rotor loading device transfers the rotor from the material tray to the rotor loading conveyor line 31 for conveying. The rotor loading conveyor line 31 uses synchronously moving conveyor belts 311. Based on the guide limiting mechanism 312 limiting the rotors conveyed on it, when placing the rotor on the rotor loading conveyor line 31, it is only necessary to align and place it between the two conveyor belts 311. This not only makes the structural design relatively simple, but also makes it easy to position the rotor on the rotor loading conveyor line 31.

[0064] After the rotor is conveyed to its position on the rotor loading conveyor line 31, the rotor loading gripping module 32 grips the rotor and transfers it to the template 22. The rotor loading gripping module 32 typically includes a gripping robot and a robot moving module for robot transfer, which is a conventional design in the field and will not be described in detail here. It should also be noted that other gripping and transfer devices involving rotors in the technical solution of this application have similar structures, such as the rotor unloading device 6, and will not be described in detail in the technical solution of this application.

[0065] In some embodiments, the template 22 includes a template base 221 and a magnetic suction member 222; the template base 221 is mounted on the periphery of the rotor body, and a placement position for placing the rotor is formed on the template base 221, the placement position supporting the rotor from the bottom; the magnetic suction member 222 is disposed in the template base 221 corresponding to the placement position, for magnetically attracting and fixing the rotor on the placement position.

[0066] In this embodiment, when the rotor is placed on the template base 221, the template base 221 can support the rotor from the bottom and fix the rotor by the magnetic suction member 222. In the process of pressing down the rotor during the installation of the commutator, it can abut the rotor from the bottom to assist the assembly of the commutator.

[0067] The magnetic suction component 222 is disposed on the template base 221 next to the placement position. The placement position is a semi-circular groove. Multiple magnetic suction components 222 are provided, and the magnetic suction component 222 can be a magnet.

[0068] Furthermore, after the rotor is transferred and placed on the template 22, the turntable body 21 rotates, causing the template 22 to move to the detection and flipping device 4. (See also...) Figure 1 As shown, the detection and flipping device 4 includes a vision detection mechanism 42 and a flipping reversing component 41; the vision detection mechanism 42 is used to detect whether the rotor on the template 22 is placed in a predetermined direction; the flipping reversing component 41 is disposed below the vision detection mechanism 42 and is disposed in conjunction with the template 22, and the flipping reversing component 41 is used to adjust the direction of the rotor on the template 22 when the vision detection mechanism 42 detects that the rotor is placed in a non-predetermined direction.

[0069] In this embodiment, the visual inspection mechanism 42 can be a CCD visual inspection machine. It is understood that the rotor has a locking hole on the side where the commutator is mounted, which matches the commutator claw. If this locking hole is not present on the upward-facing side of the rotor on the template 22, the rotor is considered to be placed in the opposite direction on the template 22, and the commutator assembly in the next station cannot proceed. Therefore, the purpose of the visual inspection mechanism 42 in this embodiment is to determine whether the rotor placement on the template 22 is correct by detecting whether the locking hole is present on the upward-facing side of the rotor. If the locking hole is present on the rotor, the rotor continues to move with the template 22 to the next station for commutator assembly. If the locking hole is not present on the rotor, the flipping and reversing assembly 41 starts to operate, flipping the rotor at 180 degrees for reversal before continuing to move to the next station.

[0070] The flipping and reversing assembly 41 can rotate 180 degrees relative to the rotor feeding and gripping module 32, thereby driving the rotor to reverse direction.

[0071] Furthermore, the rotor is transferred along with the template 22 to the commutator assembly device 5 for commutator assembly.

[0072] See Figure 1 As shown, in some embodiments, the commutator assembly device 5 includes a commutator pre-assembly device 51 and a commutator pressing and positioning device 52, which respectively realize the pre-pressing of the commutator and the fine pressing of the commutator into place; thus, the installation of the commutator is divided into the above two steps to ensure the accuracy of the commutator installation.

[0073] See Figure 3 as well as Figure 4 As shown, the commutator pre-assembly device 51 includes a vibratory feeding mechanism 53 and a material picking pre-assembly mechanism 54 docked to the vibratory feeding mechanism 53. The vibratory feeding mechanism 53 is used to provide orderly conveying of the commutator, and the material picking pre-assembly mechanism 54 is used to grab the commutator and pre-press it onto the rotor.

[0074] Specifically, the vibratory feeding mechanism 53 includes a vibratory plate mechanism 531 and a linear vibration mechanism 532. The linear vibration mechanism 532 is connected to the output end of the vibratory plate mechanism 531, and the screening and conveying of the commutator is achieved through the cooperation between the vibratory plate mechanism 531 and the linear vibration mechanism 532. The conveying path of the linear vibration mechanism 532 is a straight-through type, meaning that the commutator can be continuously conveyed along its conveying path on the linear vibration mechanism 532 until it detaches. Therefore, a stop mechanism 533 is provided at the output end of the linear vibration mechanism 532. This stop mechanism 533 is used to position the commutator conveyed on the linear vibration mechanism 532 and prevent the commutator from detaching.

[0075] The purpose of designing the conveying path of the linear vibration mechanism 532 as a straight-through type is to facilitate the transfer of the commutator in conjunction with the material handling and pre-loading mechanism 54. The transfer process includes: the linear vibration mechanism 532 conveys the commutator until it is blocked and positioned by the blocking mechanism 533; the material handling and pre-loading mechanism 54 grabs the positioned rotor and continues to move along the conveying path of the linear vibration mechanism 532. This process will push the blocking mechanism 533 to open the conveying path of the linear vibration mechanism 532 that it was blocked, until the material handling and pre-loading mechanism 54 grabs the commutator and disengages it along the conveying path.

[0076] To enable the relevant actions of the material stopping mechanism 533, this material stopping mechanism 533 is movable. (See reference...) Figure 4 As shown, in some embodiments, the material blocking mechanism 533 includes a stop block 5331 and a telescopic spring 5332; one end of the stop block 5331 is placed horizontally on the conveying path of the linear vibration mechanism 532, and the other end is rotatably set; one end of the telescopic spring 5332 is connected to the other end of the stop block 5331, and the other end is fixedly set; wherein, when the stop block 5331 rotates along the conveying direction of the linear vibration mechanism 532, the telescopic spring 5332 deforms.

[0077] Furthermore, when the pre-loading mechanism 54 picks up the positioned rotor and moves it along the conveying path of the linear vibration mechanism 532, it pushes the stop block 5331 to rotate around its other end, thereby opening the blocked conveying path of the linear vibration mechanism 532. During this process, the telescopic spring 5332 deforms, typically by being stretched. After the commutator transfer is completed, under the restoring force of the telescopic spring 5332, the rotating stop block 5331 returns to its original position, continuing to block the next commutator conveyed by the linear vibration mechanism 532. To ensure that the stop block 5331 returns to the same position each time and achieves accurate commutator positioning, a stop structure can be provided for the return action of the stop block 5331. This stop structure can be a stop block (not shown in the attached figure) provided on one side of the stop block 5331.

[0078] See Figure 3As shown, in some embodiments, the material handling pre-loading mechanism 54 includes a moving module 541, a material handling component 542, and a guide sleeve assembly 545; the moving module 541 is used to drive the material handling component 542 and the guide sleeve assembly 545 to move between the vibrating feeding mechanism 53 and the template 22; the material handling component 542 is connected to the moving module 541, and the material handling component 542 includes a material handling needle 543 and a material needle drive member 544 for driving the material handling needle 543 to move in the vertical direction; the guide sleeve assembly 545 is connected to the moving module 541, and the guide sleeve assembly 545 includes a guide sleeve 546, a guide sleeve mounting plate 547, and a guide sleeve drive member 548, the guide sleeve 546 is connected to the guide sleeve drive member 548 through the guide sleeve mounting plate 547, and the guide sleeve drive member 548 is used to drive the guide sleeve 546 to move in the vertical direction; the guide sleeve 546 is sleeved on the material handling needle 543.

[0079] In this embodiment, a pick-up needle 543 is used to grasp the commutator positioned on the linear vibration mechanism 532. It is understood that when the commutator is assembled on the rotor, a mounting hole is provided in the middle of the commutator for assembly with the shaft in the rotor. In this embodiment, the grasping process of the commutator on the linear vibration mechanism 532 is as follows: the moving module 541 drives the pick-up assembly 542 to move above the commutator positioned on the linear vibration mechanism 532, with the pick-up needle 543 facing the mounting hole of the commutator; then, under the action of the needle drive 544, the pick-up needle 543 moves downward to insert into the mounting hole of the commutator. Because the diameter of the pick-up needle 543 is slightly larger than the diameter of the mounting hole, the pick-up needle 543 is relatively close to the mounting hole of the commutator, and the commutator will not fall off relative to the pick-up needle 543.

[0080] Then, the moving module 541 moves the commutator to mate with the rotor shaft on the template 22. Further, with the cooperation of the pick-up pin 543 and the guide sleeve assembly 545, the commutator is pre-installed on the rotor. The process includes: the guide sleeve drive 548 drives the guide sleeve 546 downwards, which in turn pushes the commutator on the pick-up pin 543 along the pick-up pin 543. When the pick-up pin 543 mates with the rotor shaft, the commutator moves and transitions onto the rotor shaft, completing the pre-installation of the commutator.

[0081] Furthermore, the template 22 moves, causing the pre-installed commutator to move onto the commutator pressing and positioning device 52 for precision pressing assembly of the commutator. The commutator pressing and positioning device 52 is located adjacent to the commutator pre-installation device 51.

[0082] See Figures 5-7As shown, in some embodiments, the commutator pressing and positioning device 52 includes a mounting base 55 and a positioning mechanism 56 and a rotating pressing mechanism 57 disposed on the mounting base 55. The positioning mechanism 56 is arranged parallel to the template 22 and is used to cooperate with the template 22 to fix the rotor. The rotating pressing mechanism 57 is used to drive the pre-pressed commutator on the rotor to rotate and press down, thereby completing the assembly between the commutator and the rotor.

[0083] In this embodiment, the fine pressing process of the commutator is as follows: while pressing down on the commutator, the commutator is driven to rotate. During this rotational pressing process, if the pawl on the commutator rotates above the corresponding pawl hole on the rotor, the pawl can engage with the pawl hole under the pressing force, thereby completing the fine pressing assembly of the commutator. Therefore, the rotor is fixed by the positioning mechanism 56, and the rotating pressing mechanism 57 drives the commutator to rotate and press down, so as to achieve the movement of the commutator relative to the rotor.

[0084] See Figure 7 As shown, in some embodiments, the positioning mechanism 56 includes a positioning block 561 and a positioning drive 562; the positioning drive 562 is connected to the mounting base 55, and the output end of the positioning drive 562 is connected to the positioning block 561. The positioning drive 562 is used to drive the positioning block 561 to move closer to or away from the rotor on the template 22.

[0085] The positioning block 561 has a fitting groove that fits the outer circumference of the rotor, which improves the fixing effect of the rotor when it is used with the template 22.

[0086] In some embodiments, a pressing slide rail is provided on the mounting base 55; the rotating pressing mechanism 57 includes a pressing drive 571 and a rotating pressing module; the pressing drive 571 is mounted on the mounting base 55; the rotating pressing module is slidably connected to the pressing slide rail and connected to the pressing drive 571, so that it can move vertically along the pressing slide rail under the drive of the pressing drive 571, and the rotating pressing module is used to drive the commutator to rotate and press down. In this way, the rotating pressing module is moved to a predetermined position in advance by the pressing drive 571. At the predetermined position, the rotating pressing module can provide a continuous pressing force to the commutator based on its own structural design, and further complete the rotating pressing action of the commutator during rotation.

[0087] See Figure 8 and Figure 7As shown, in some embodiments, the rotary pressing module includes a rotary drive 572, a pressing sleeve 573, a pressing head 574, and an elastic element (not shown in the figures); the rotary drive 572 is mounted above the mounting base 55; the pressing sleeve 573 is connected to the output end of the rotary drive 572; the pressing head 574 is partially sleeved inside the pressing sleeve 573 and can move vertically along the pressing sleeve 573, and a space is provided between the pressing head 574 and the pressing sleeve 573. An anti-rotation structure is provided, which is used for the lower pressure head 574 to rotate with the lower pressure sleeve 573; an elastic element is provided between the lower pressure sleeve 573 and the lower pressure head 574 to provide the force for the lower pressure head 574 to move downward; wherein, an anti-detachment structure is also provided between the lower pressure head 574 and the lower pressure sleeve 573 to prevent the lower pressure head 574 from detaching from the lower pressure sleeve 573. This anti-detachment structure can be an anti-detachment step provided between the pressure head body 5741 and the lower pressure sleeve 573.

[0088] In this embodiment, the pressure head 574 is a component that contacts the commutator. The continuous downward driving force is provided by an elastic element, which is a compression spring, abutting between the top of the pressure head 574 and the inner top wall of the pressure sleeve 573. The rotational action is achieved by the rotational drive 572, which drives the pressure sleeve 573 to rotate, thereby causing the pressure head 574 to rotate.

[0089] For details, please refer to Figure 7 As shown, the lower pressure head 574 includes a pressure head body 5741 and an abutment rod 5742; the lower end of the pressure head body 5741 extends relative to the lower pressure sleeve 573; the abutment rod 5742 extends downward from the lower end of the pressure head body 5741 and is used to insert between adjacent protrusions on the periphery of the commutator, and the number of abutment rods 5742 is arranged relative to the protrusions on the periphery of the commutator; wherein, when the lower pressure head 574 rotates, the abutment rod 5742 abuts against the protrusions to drive the commutator to rotate.

[0090] Understandably, when the rotary drive 572 drives the pressure head 574 to rotate, the abutment rod 5742 rotates, and the abutment rod 5742 further abuts against the protrusions provided on the periphery of the commutator, thereby pushing the commutator to rotate. The pressure head body 5741 in the middle part surrounded by multiple abutment rods 5742 can then press against the top of the commutator.

[0091] In some embodiments, the anti-rotation structure includes an anti-rotation pin (not shown in the figures) connecting the pressing head 574 and the pressing sleeve 573. The anti-rotation pin is disposed on the side wall of the pressing head 574. The side wall of the pressing sleeve 573 is provided with a waist-shaped clearance hole. The anti-rotation pin passes through the waist-shaped clearance hole and can move vertically along the waist-shaped clearance hole.

[0092] In this embodiment, the pressing head 574 and the pressing sleeve 573 are connected by an anti-rotation pin so that the pressing head 574 can move when the pressing sleeve 573 rotates. The pressing head 574 can move vertically relative to the pressing sleeve 573. Therefore, a waist-shaped clearance hole is provided so that when the pressing head 574 moves in the vertical direction, the anti-rotation pin can move along with the pressing head 574 to avoid it.

[0093] See Figure 6 As shown, in some embodiments, the rotary pressing module further includes a detection structure 575, which includes a connecting plate 5751, a test plate 5752, and a sensing detection mechanism 5753. The connecting plate 5751 is connected to the pressing sleeve 573. The test plate 5752 passes through the pressing sleeve 573 and is connected to the pressing head 574, and can move vertically with the pressing head 574. The sensing detection mechanism 5753 is mounted on the connecting plate 5751 and docks with the test plate 5752.

[0094] In this embodiment, with this structural arrangement, the sensing and detection mechanism 5753 and the test plate 5752 rotate synchronously with the pressing sleeve 573. During the movement of the pressing head 574, the test plate 5752 will further follow the pressing head 574. The sensing and detection mechanism 5753 is used to detect the movement of the test plate 5752 to determine whether the commutator is precisely pressed into place.

[0095] The principle is as follows: when the commutator is precisely pressed into place, the commutator's claws will engage with the rotor's locking holes, causing the commutator to move downwards a certain distance based on the height difference, thereby driving the test board 5752 to move. The sensing and detection mechanism 5753 detects the movement of the test board 5752.

[0096] More specifically, the sensing and detection mechanism 5753 is an infrared sensor, and the test board 5752 has a light-avoiding hole for the infrared light emitted from the infrared sensor to pass through. When the commutator is precisely pressed into place, the light-avoiding hole on the test board 5752 is just enough for the infrared optical fiber of the infrared sensor to pass through, thus achieving the detection purpose.

[0097] After the commutator is assembled by precision pressing, the rotor on the template 22 is transferred by the rotor unloading device 6 to the circulating material receiving device 7 for unloading and conveying. The rotor unloading device 6 will not be described in detail.

[0098] See Figures 9-12As shown, in some embodiments, the circulating material receiving device 7 includes a first conveying mechanism 71, a second conveying mechanism 72, a fixture changing mechanism 73, and a turnover platform 74; the first conveying mechanism 71 includes a first conveyor belt 711 for feeding and conveying the rotor fixture 75; the second conveying mechanism 72 includes a second conveyor belt 721 parallel to the first conveyor belt 711 and disposed below the rotor unloading device 6 for unloading the rotor; the fixture changing mechanism 73 is disposed between the tail end of the first conveyor belt 711 and the head end of the second conveyor belt 721 for transferring the rotor fixture 75 from the first conveyor belt 711 to the second conveyor belt 721; the turnover platform 74 is disposed between the head end of the first conveyor belt 711 and the tail end of the second conveyor belt 721 for parking and turnover of the rotor fixture 75.

[0099] In this embodiment, a rotary mechanism for the rotor fixture 75 is constructed by a first conveying mechanism 71, a second conveying mechanism 72, a fixture changing mechanism 73, and a turnover platform 74. The rotary process is as follows: an empty rotor fixture 75 at the turnover platform 74 is manually placed on the first conveyor belt 711 of the first conveying mechanism 71 for conveying. When it reaches its end, the fixture changing mechanism 73 transfers the rotor fixture 75 on the first conveyor belt 711 to the second conveyor belt 721 of the second conveying mechanism 72 for conveying. When the rotor fixture 75 is conveyed to a predetermined position on the second conveyor belt 721, the rotor unloading device 6 transfers the rotor on the template 22 to the rotor fixture 75 and continues to convey the rotor fixture 75 with the rotor to the turnover platform 74. At the turnover platform 74, the rotor in the rotor fixture 75 is transferred, and then the empty rotor fixture 75 is placed on the first conveyor belt 711 for cyclic conveying.

[0100] In this way, the process of unloading and conveying the rotor on the template 22 is completed. Moreover, this rotary mechanism can realize the recycling and processing of the rotor fixture 75 at the turnover platform 74, which can reduce the handling time of the rotor fixture 75, improve production efficiency, and save costs.

[0101] See Figure 10 As shown, in some embodiments, limit guide plates 77 are provided on both sides of the first conveyor belt 711 and the second conveyor belt 721; the rotor fixture 75 has a plurality of receiving cavities 751 along the conveying direction of the conveyor belt; wherein, the rotor fixture 75 has slots 752 on both sides corresponding to each receiving cavity 751, and the rotor unloading device 6 is movably provided with a first locking block 76 on one side of the second conveyor belt 721, the first locking block 76 being used to lock into the slots 752 on the rotor fixture 75.

[0102] In this embodiment, the first locking block 76 is used to cooperate with the locking slot 752 on the rotor fixture 75 so that the rotor fixture 75 is limited to the lower part of the rotor unloading device 6, so as to facilitate the rotor unloading device 6 to transfer the rotor onto the rotor fixture 75.

[0103] Understandably, the slots 752 correspond to the respective receiving cavities 751. During the rotor unloading process, when the first locking block 76 engages in the corresponding slot 752, the receiving cavity 751 corresponding to that slot 752 is positioned below the rotor unloading device 6, facilitating the transfer of the rotor to that receiving cavity 751. For example, the rotor fixture 75 is provided with a first receiving cavity 751, a second receiving cavity 751, a third receiving cavity 751, and a fourth receiving cavity 751. Corresponding to the first receiving cavity 751-the fourth receiving cavity 751, first slots 752-fourth slots 752 are respectively provided on the side of the rotor fixture 75. During the rotor unloading process, when the first locking block 76 is driven to engage in the first slot 752, the first receiving cavity 751 corresponds to the rotor unloading device 6 positioned above it, and the rotor unloading device... The rotor fixture 75 can grasp the rotor on the template 22 and transfer it for unloading. After the rotor is placed in the first receiving cavity 751, the first locking block 76 can exit the first locking slot 752. The rotor fixture 75 continues to move under the conveying of the second conveyor belt 721, and the first locking block 76 can further engage with the second locking slot 752 so that the second receiving cavity 751 corresponds to the rotor unloading device 6 set above. The rotor unloading device 6 can continue to grasp the rotor on the template 22 and transfer it to the second receiving cavity 751. Therefore, based on the cooperation between the first locking block 76 and the locking slot 752, the receiving cavity 751 on the rotor fixture 75 can be sequentially aligned with the rotor unloading device 6 above, and the rotor unloading is completed by the rotor loading device 3.

[0104] In some embodiments, a proximity sensor (not shown in the figures) is movably disposed on one side of the second conveyor belt 721 corresponding to the rotor feeding device 6, and a sensing element adapted to the proximity sensor is disposed on each receiving cavity 751 of the rotor fixture 75. In this way, by providing a proximity sensor and corresponding sensing elements on the rotor fixture 75, the first locking block 76 can be easily and accurately locked into the slot 752 of the template 22. The sensing element is a metal part.

[0105] In some embodiments, a material detector is provided on the side of the second conveyor belt 721 corresponding to the rotor feeding device 6. The material detector is used to detect whether the rotor feeding device 6 has a rotor placed on the rotor fixture 75. In this way, after detecting that the rotor feeding transfer is completed, the system can control the first locking block 76 to release the rotor fixture 75 to continue moving.

[0106] In some embodiments, a second locking block (not shown in the figures) is movably disposed on one side of the first conveyor belt 711. The second locking block is used to engage with the slot 752 on the rotor fixture 75, and a proximity sensor is adapted to each second locking block. Furthermore, when the rotor fixture 75 is conveyed on the first conveyor belt 711, the conveying of the rotor fixture 75 can be paused based on the cooperation between the second locking block and the slot 752, so as to buffer the conveying pressure.

[0107] See Figure 11 As shown, in some embodiments, the fixture changing mechanism 73 includes a docking plate 731, a pusher plate 732, and a position sensor; one end of the docking plate 731 is docked to the tail end of the first conveyor belt 711, and the other end is docked to the head end of the second conveyor belt 721; the pusher plate 732 is movably disposed to dock with the first conveyor belt 711, and is used to push the rotor fixture 75 from the tail end of the first conveyor belt 711 to the head end of the second conveyor belt 721; the detection path of the position sensor covers the tail end of the first conveyor belt 711 and the head end of the second conveyor belt 721, and is used to detect whether the rotor fixture 75 has been conveyed into place.

[0108] In this embodiment, the docking plate 731 is disposed between the first conveyor belt 711 and the second conveyor belt 721. When the push plate 732 pushes the rotor fixture 75, the rotor fixture 75 moves on the docking plate 731 to transfer to the second conveyor belt 721. The push plate 732 is an "L"-shaped plate, which includes a first plate body 7321 and a second plate body 7322. Its initial position is docked at the tail end of the first conveyor belt 711. When the rotor fixture 75 is conveyed along the first conveyor belt 711, the rotor fixture 75 can be confined within the angled space formed by the first plate body 7321 and the second plate body 7322. In this way, on the one hand, the rotor fixture 75 is prevented from detaching from the first conveyor belt 711, and on the other hand, the stability of the push plate 732 pushing the rotor fixture 75 is improved.

[0109] See Figure 12 As shown, in some embodiments, the turnover platform 74 includes a table 741 and a pushing assembly 742; the table 741 is connected to the first end of the first conveyor belt 711 and the tail end of the second conveyor belt 721; the pushing assembly 742 is disposed on one side of the table 741 near the second conveyor belt 721, and is used to push the rotor fixture 75 conveyed by the second conveyor belt 721 onto the other side of the table 741.

[0110] In this embodiment, the pusher assembly 742 can clean the table 741 in a timely manner so that the second conveyor belt 721 can continue to transport the rotor fixture 75 to the table 741; while on the other side of the table 741, the operator can transfer the rotor on the rotor fixture 75.

[0111] Specifically, the pusher assembly 742 includes a pusher drive 7421 and a jig pusher plate 7422; the jig pusher plate 7422 is connected to the output end of the pusher drive 7421 and is used to push the rotor jig 75 to move under the drive of the pusher drive 7421.
