[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0051] See also Figure 1 as well as Figure 2 As shown, the present application provides a commutator installation device. The commutator installation device includes a frame 1, a turntable assembly 2 rotatably arranged 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 receiving device 7 arranged on the frame 1 in sequence around the turntable assembly 2; wherein the turntable assembly 2 includes a turntable body 21 and a plurality of support molds 22 for magnetically attracting the rotor arranged on the circumference of the turntable body 21; the rotation of the turntable assembly 2 can drive the support molds 22 to connect with the rotor loading device 3, the detection and flipping device 4, the commutator assembly device 5 and the rotor unloading device 6 in sequence; the circulating material receiving device 7 is arranged to connect with the rotor unloading device 6 for the cyclic conveying of the jig.

[0052] The technical solution of the present application uses the rotor feeding device 3 to move to the workstations corresponding to each device after loading the material onto the backing mold 22, and each device cooperates with the backing mold 22 to realize the assembly operation of the commutator, which has a high degree of automation and can efficiently and accurately install the commutator.

[0053] See also Figure 8 As shown, in some embodiments, the rotor feeding device 3 includes a rotor feeding conveyor line 31 and a rotor feeding grabbing module 32; the rotor feeding conveyor line 31 includes two parallel and synchronous conveying belts 311, and a guide limiting mechanism 312 is arranged along the conveying direction of the two conveying belts 311, and the rotor is supported between the two conveying belts 311 and conveyed along the guide limiting mechanism 312; the rotor feeding grabbing module 32 is docked and arranged between the rotor feeding conveyor line 31 and the backing mold 22, and is used to grab and transfer the rotor on the rotor feeding conveyor line 31 to the backing mold 22.

[0054] In this embodiment, the rotor feeding conveyor line 31 is connected to a processing device, such as a rotor feeding device, which transfers the rotor from the material tray to the rotor feeding conveyor line 31 for conveying. The rotor feeding conveyor line 31 uses a synchronous conveying belt 311, and based on the limiting of the rotor conveyed thereon by the guide limiting mechanism 312, when placing the rotor on the rotor feeding conveyor line 31, it only needs to be aligned and placed between the two conveying belts 311. Not only is the structural design relatively simple, but it is also easy to position and place the rotor on the rotor feeding conveyor line 31.

[0055] After the rotor is delivered to the rotor feeding conveyor line 31, the rotor feeding grabbing module 32 grabs the rotor and transfers it to the support mold 22. The rotor feeding grabbing module 32 usually includes a grabbing manipulator and a manipulator moving module for manipulator transfer, which is a conventional design method in the field and will not be described in detail here. It should be noted that other grabbing and transferring devices involving the rotor in the technical solution of this application are of similar structure, such as the rotor unloading device 6, which will not be described in detail in the technical solution of this application.

[0056] In some embodiments, the mold 22 includes a mold base 221 and a magnetic member 222; the mold base 221 is installed on the circumferential side of the rotor body, and a placement position for placing the rotor is formed on the mold base 221, and the placement position supports the rotor from the bottom; the magnetic member 222 is arranged in the mold base 221 corresponding to the placement position, and is used to magnetically fix the rotor on the placement position.

[0057] In this embodiment, when the rotor is placed on the mold base 221, the mold base 221 can support the rotor from the bottom and can fix the rotor through the magnetic attraction part 222. Then, when the commutator needs to be installed and the rotor needs to be pressed down, it can abut the rotor from the bottom to assist the assembly of the commutator.

[0058] The magnetic attraction member 222 is arranged on the supporting mold base 221 beside the placement position, and the placement position is a semi-arc-shaped supporting groove. There are multiple magnetic attraction members 222, and the magnetic attraction members 222 can be magnets.

[0059] Furthermore, after the rotor is transferred and placed on the template 22, the turntable body 21 rotates to drive the template 22 to move to the detection flipping device 4. Figure 1 As shown, the detection flipping device 4 includes a visual detection mechanism 42 and a flipping and reversing component 41; the visual detection mechanism 42 is used to detect whether the rotor on the mold 22 is placed in a predetermined direction; the flipping and reversing component 41 is arranged below the visual detection mechanism 42 and is connected to the mold 22. The flipping and reversing component 41 is used to adjust the direction of the rotor on the mold 22 when the visual detection component detects that the rotor is placed in a non-predetermined direction.

[0060] In this embodiment, the visual inspection mechanism 42 can be a CCD visual inspection machine. It can be understood that a hole that matches the commutator claw is provided on one side of the rotor for mounting the commutator. When there is no hole on the upward side of the rotor on the backing mold 22, it is considered that the placement direction of the rotor on the backing mold 22 is in the opposite direction. At this time, the assembly of the commutator in the next station cannot be performed. Therefore, the purpose of setting the visual inspection mechanism 42 in this embodiment is to determine whether the placement state of the rotor on the backing mold 22 is correct by detecting whether there is the hole on the upward side of the rotor. If the hole is detected on the rotor, the rotor continues to be transferred to the next station with the backing mold 22 for commutator assembly. When there is no hole on the rotor, the flipping switching assembly 41 starts to work, so as to flip the rotor 180 degrees for commutation and then continue to transfer to the next station.

[0061] The reversing component 41 can realize a 180-degree rotation of the manipulator relative to the rotor feeding and grabbing module 32, thereby driving the rotor to reverse.

[0062] Further, the rotor is transferred along with the template 22 to the commutator assembly device 5 for commutator assembly.

[0063] See also Figure 1 As shown, in some embodiments, the commutator assembly device 5 includes a commutator pre-installation device 51 and a commutator downward pressing and positioning device 52, which respectively realize the pre-pressing of the commutator and the precision pressing of the commutator into place; in this way, the installation of the commutator is divided into the above two steps to ensure the accuracy of the commutator installation.

[0064] See also Figure 3 as well as Figure 4 As shown, the commutator pre-installation device 51 includes a vibrating feeding mechanism 53 and a material picking and pre-installation mechanism 54 connected to the vibrating feeding mechanism 53. The vibrating feeding mechanism 53 is used to provide orderly conveyed commutators, and the material picking and pre-installation mechanism 54 is used to grab the commutator and pre-press it onto the rotor.

[0065] Specifically, the vibrating feeding mechanism 53 includes a vibration plate mechanism 531 and a direct vibration mechanism 532; the direct vibration mechanism 532 is connected to the output end of the vibration plate mechanism 531, and the screening and conveying of the commutator is realized through the cooperation between the vibration plate mechanism 531 and the direct vibration mechanism 532. The conveying path of the direct vibration mechanism 532 is a straight-through type, which means that the commutator can be conveyed along its conveying path on the direct vibration mechanism 532 until it is separated. Therefore, a material blocking mechanism 533 is provided at the output end of the direct vibration mechanism 532, and the material blocking mechanism 533 is used to position the commutator conveyed on the direct vibration mechanism 532 to prevent the commutator from being separated.

[0066] The purpose of designing the conveying path of the direct vibration mechanism 532 as a straight-through type is to facilitate the transfer of the commutator in cooperation with the material picking and pre-loading mechanism 54. The transfer process includes: the direct vibration mechanism 532 conveys the commutator until it is blocked and positioned by the material blocking mechanism 533, the material picking and pre-loading mechanism 54 grabs the positioned rotor and continues to move along the conveying path of the direct vibration mechanism 532. This process will push the material blocking mechanism 533 to open the blocked conveying path of the direct vibration mechanism 532 until the material picking and pre-loading mechanism 54 grabs the commutator and disengages along the conveying path.

[0067] In order to realize the related actions of the material blocking mechanism 533, the material blocking mechanism 533 is movable. Figure 4 As shown, in some embodiments, the material blocking mechanism 533 includes a block 5331 and a telescopic spring 5332; one end of the block 5331 is placed horizontally on the conveying path of the direct vibration mechanism 532, and the other end is rotatably arranged; one end of the telescopic spring 5332 is connected to the other end of the block 5331, and the other end is fixedly arranged; wherein, when the block 5331 rotates along the conveying direction of the direct vibration mechanism 532, the telescopic spring 5332 is deformed.

[0068] Furthermore, when the material picking and preloading mechanism 54 grabs the positioned rotor and moves it along the conveying path of the direct vibration mechanism 532, it will push the block 5331 to rotate around its other end to open the blocked conveying path of the direct vibration mechanism 532. In this process, the telescopic spring 5332 is deformed, and the deformation is usually stretched. Then, after the commutator transfer is completed, under the restoring force of the telescopic spring 5332, the rotating block 5331 will return to its original position and continue to block the next commutator conveyed by the direct vibration mechanism 532. Among them, in order to ensure that the block 5331 returns to the same position each time and realize the accuracy of the commutator positioning, a stop structure can be set for the return action of the block 5331, and the stop structure can be a stop block set on one side of the corresponding block 5331 (not shown in the drawings).

[0069] See also Figure 3 As shown, in some embodiments, the material picking preloading mechanism 54 includes a moving module 541, a material picking assembly 542 and a guide sleeve assembly 545; the moving module 541 is used to drive the material picking assembly 542 and the guide sleeve assembly 545 to move between the vibration feeding mechanism 53 and the support mold 22; the material picking assembly 542 is connected to the moving module 541, and the material picking assembly 542 includes a material picking needle 543 and a material needle driving member 544 for driving the material picking 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 driving member 548, the guide sleeve 546 is connected to the guide sleeve driving member 548 through the guide sleeve mounting plate 547, and the guide sleeve driving 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 picking needle 543.

[0070] In this embodiment, the material picking needle 543 is used to complete the grabbing of the commutator positioned on the direct vibration mechanism 532. It can be understood that when the commutator is assembled on the rotor, an assembly hole for assembling with the rotating shaft in the rotor is opened in the middle of the commutator. In this embodiment, the grabbing process of the commutator on the direct vibration mechanism 532 is as follows: the moving module 541 drives the material picking component 542 to move to the top of the commutator positioned on the direct vibration mechanism 532, and the material picking needle 543 faces the assembly hole of the commutator; then, under the action of the material needle driving member 544, the material picking needle 543 moves downward to be inserted into the assembly hole of the commutator. Because the diameter of the material picking needle 543 is slightly larger than the diameter of the assembly hole, the material picking needle 543 and the assembly hole of the commutator are relatively tight, and the commutator will not fall off relative to the material picking needle 543.

[0071] Then, the moving module 541 drives the commutator to move and dock with the rotating shaft of the rotor on the support mold 22, and further, with the cooperation of the material picking needle 543 and the guide sleeve assembly 545, the commutator is pre-installed on the rotor. The process includes: the guide sleeve driving member 548 drives the guide sleeve 546 to move downward, and then the commutator on the material picking needle 543 can be pushed to move along the material picking needle 543. When the material picking needle 543 docks with the rotating shaft of the rotor, the commutator moves and transitions to the rotating shaft of the rotor, completing the pre-installation of the commutator.

[0072] Furthermore, the mold 22 moves, driving the pre-assembled commutator to move to the commutator pressing and positioning device 52 for precision pressing and assembly of the commutator. The commutator pressing and positioning device 52 is arranged adjacent to the commutator pre-assembly device 51.

[0073] See also Figure 5-Figure 7 As shown, in some embodiments, the commutator pressing down positioning device 52 includes a mounting seat 55 and a positioning mechanism 56 and a rotating pressing down mechanism 57 arranged on the mounting seat 55. The positioning mechanism 56 is arranged parallel to the backing mold 22 and is used to cooperate with the backing mold 22 to achieve the fixation of the rotor; the rotating pressing down mechanism 57 is used to drive the pre-pressed commutator on the rotor to rotate and press down, so as to complete the assembly between the commutator and the rotor.

[0074] In this embodiment, the commutator precision pressing process is to drive the commutator to rotate while pressing the commutator. During the rotation and pressing process, if the claw on the commutator rotates to the top of the corresponding clamping hole on the rotor, the claw can be clamped into the clamping hole under the pressing force, thereby completing the precision 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, so as to achieve the relative movement of the commutator relative to the rotor.

[0075] See also Figure 7As shown, in some embodiments, the positioning mechanism 56 includes a positioning block 561 and a positioning driver 562; the positioning driver 562 is connected to the mounting seat 55, and the output end of the positioning driver 562 is connected to the positioning block 561, and the positioning driver 562 is used to drive the positioning block 561 to move closer to or away from the rotor on the mold 22.

[0076] The positioning block 561 is provided with a fitting groove formed to fit the outer circumference of the rotor, thereby achieving a better fixing effect on the rotor when cooperating with the template 22.

[0077] In some embodiments, a pressing rail is provided on the mounting seat 55; the rotating pressing mechanism 57 includes a pressing driving member 571 and a rotating pressing module; the pressing driving member 571 is mounted on the mounting seat 55; the rotating pressing module is slidably connected to the pressing rail and connected to the pressing driving member 571, so as to move in the vertical direction along the pressing rail under the drive of the pressing driving member 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 driven to move to a predetermined position by the pressing driving member 571 in advance, and at the predetermined position, the rotating pressing module can provide a continuous pressing force for the commutator based on its own structural design, and further complete the rotating pressing action of the commutator when rotating.

[0078] See also Figure 8 and Figure 7 As shown, in some embodiments, the rotary pressing module includes a rotary driving member 572, a pressing sleeve 573, a pressing head 574 and an elastic member (not shown in the drawings); the rotary driving member 572 is installed above the mounting seat 55; the pressing sleeve 573 is connected to the output end of the rotary driving member 572; the pressing head 574 is partially sleeved in the pressing sleeve 573 and can move along the pressing sleeve 573 in the vertical direction, and a spring is provided between the pressing head 574 and the pressing sleeve 573. An anti-rotation structure is provided, and the anti-rotation structure is used for the downward pressure head 574 to rotate along with the downward pressure sleeve 573; an elastic member is provided between the downward pressure sleeve 573 and the downward pressure head 574, and is used to provide a force for the downward pressure movement of the downward pressure head 574; wherein, an anti-slip structure is also provided between the downward pressure head 574 and the downward pressure sleeve 573, and is used to prevent the downward pressure head 574 from detaching from the downward pressure sleeve 573, and the anti-slip structure can be an anti-slip step provided between the pressure head body 5741 and the downward pressure sleeve 573.

[0079] In this embodiment, the pressing head 574 is a component in contact with the commutator. The continuous pressing driving force is provided by an elastic member, which is a compression spring, and the compression spring abuts between the top of the pressing head 574 and the top inner wall of the pressing sleeve 573. The rotation action is driven by the rotating driving member 572 to drive the pressing sleeve 573 to rotate and then drive the pressing head 574 to rotate.

[0080] For details, see Figure 7As shown, the lower pressure head 574 includes a pressure head body 5741 and a push rod 5742; the lower end of the pressure head body 5741 extends relative to the lower pressure sleeve 573; the push rod 5742 extends downward from the end portion of the lower end of the pressure head body 5741, and is used to be inserted between adjacent protrusions on the peripheral side of the commutator, and the number of the push rods 5742 is set relative to the protrusions on the peripheral side of the commutator; wherein, when the lower pressure head 574 rotates, the push rod 5742 abuts against the protrusion to drive the commutator to rotate.

[0081] It is understandable that when the rotary drive member 572 drives the lower pressure head 574 to rotate, the abutting rod 5742 rotates, and the abutting rod 5742 further abuts against the protrusions arranged on the circumference of the commutator, thereby driving the commutator to rotate. The pressure head body 5741 in the middle part surrounded by the abutting rods 5742 can abut against the top of the commutator.

[0082] In some embodiments, the anti-rotation structure includes an anti-rotation pin (not shown in the drawings) connecting the down-pressing head 574 and the down-pressing sleeve 573, and the anti-rotation pin is arranged on the side wall of the down-pressing head 574; wherein, the side wall of the down-pressing sleeve 573 is provided with a waist-shaped avoidance hole, and the anti-rotation pin is passed through the waist-shaped avoidance hole and can move in the vertical direction along the waist-shaped avoidance hole.

[0083] In this embodiment, the pressure down head 574 and the pressure down sleeve 573 are connected by an anti-rotation pin to drive the pressure down head 574 to move when the pressure down sleeve 573 rotates, and the pressure down head 574 can move in the vertical direction within the pressure down sleeve 573 relative to the pressure down sleeve 573. Therefore, a waist-shaped avoidance hole is provided so that when the pressure down head 574 moves in the vertical direction, the anti-rotation pin can follow the movement of the pressure down head 574 to avoid it.

[0084] See also Figure 6 As shown, in some embodiments, the rotary pressing module also includes a detection structure 575, and the detection structure 575 includes a connecting plate 5751, a test plate 5752 and a sensor 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 in the vertical direction with the pressing head 574; the sensor detection mechanism 5753 is installed on the connecting plate 5751 and docked with the test plate 5752.

[0085] In this embodiment, through this structural setting, the sensor detection mechanism 5753 and the test plate 5752 rotate synchronously with the pressing sleeve 573, and during the movement of the pressing head 574, the test plate 5752 will further move with the pressing head 574. Among them, the sensor detection mechanism 5753 is used to detect the movement of the test plate 5752 and then determine whether the commutator is precisely pressed in place.

[0086] The principle is as follows: when the commutator is pressed into place, the claws on the commutator are inserted into the holes on the rotor, and the commutator moves downward for a certain distance based on the height difference, thereby driving the test plate 5752 to move, and the sensor detection mechanism 5753 detects the movement of the test plate 5752.

[0087] More specifically, the sensing detection mechanism 5753 is an infrared sensor, and a light avoidance hole for the infrared light emitted by the infrared sensor to pass through is opened on the test board 5752. When the commutator is precisely pressed in place, the light avoidance hole on the test board 5752 is just enough for the infrared optical fiber of the infrared sensor to pass through, thereby achieving the detection purpose.

[0088] After the commutator is assembled by precision pressing, the rotor on the mold 22 is transferred to the circulating material receiving device 7 for unloading and conveying by the rotor unloading device 6, and the rotor unloading device 6 will not be described in detail.

[0089] See also Figure 9-12 As shown, in some embodiments, the circulating material receiving device 7 includes a first conveying mechanism 71, a second conveying mechanism 72, a jig line changing mechanism 73 and a turnover platform 74; the first conveying mechanism 71 includes a first conveying belt 711 for loading and conveying the rotor jig 75; the second conveying mechanism 72 includes a second conveying belt 721 parallel to the first conveying belt 711 and arranged below the rotor unloading device 6, for unloading and conveying the rotor; the jig line changing mechanism 73 is arranged between the tail end of the first conveying belt 711 and the head end of the second conveying belt 721, for transferring the rotor jig 75 from the first conveying belt 711 to the second conveying belt 721; the turnover platform 74 is arranged between the head end of the first conveying belt 711 and the tail end of the second conveying belt 721, for parking and turnover of the rotor jig 75.

[0090] In this embodiment, a rotating mechanism of the rotor jig 75 is constructed by the first conveying mechanism 71, the second conveying mechanism 72, the jig line changing mechanism 73 and the turnover platform 74, and the rotation process is as follows: the empty rotor jig 75 at the turnover platform 74 is manually placed on the first conveying belt 711 on the first conveying mechanism 71 for conveying, and when it is conveyed to its tail end, the jig line changing mechanism 73 transfers the rotor jig 75 on the first conveying belt 711 to the second conveying belt 721 on the second conveying mechanism 72 for conveying, wherein, when the rotor jig 75 is conveyed to a predetermined position on the second conveying belt 721, the rotor unloading device 6 transfers the rotor on the mold 22 to the rotor jig 75, and continues to convey the rotor jig 75 with the rotor placed thereon to the turnover platform 74, and at the turnover platform 74, the rotor in the rotor jig 75 is transferred, and then the empty rotor jig 75 is placed on the first conveying belt 711 for cyclic conveying.

[0091] In this way, the unloading and conveying process of the rotor on the mold 22 is completed, and the rotary mechanism can realize the recovery and processing of the rotor fixture 75 at the turnover platform 74, which can reduce the transportation time of the rotor fixture 75, improve production efficiency and save costs.

[0092] See also Fig.10 As shown, in some embodiments, limiting guide plates 77 are provided on both sides of the first conveyor belt 711 and the second conveyor belt 721; a rotor fixture 75 is provided with a plurality of accommodating holes 751 along the conveying direction of the conveyor belt; wherein, a card slot 752 is provided on both sides of the rotor fixture 75 corresponding to each accommodating hole 751, and a first card block 76 is movably provided on one side of the second conveyor belt 721 corresponding to the rotor unloading device 6, and the first card block 76 is used to be inserted into the card slot 752 on the rotor fixture 75.

[0093] In this embodiment, the function of the first clamping block 76 is to cooperate with the clamping slot 752 on the rotor fixture 75 so that the rotor fixture 75 is limited below the rotor unloading device 6 , thereby facilitating the rotor unloading device 6 to transfer the rotor onto the rotor fixture 75 .

[0094] It can be understood that the slots 752 are opened corresponding to the receiving holes 751. During the rotor unloading process, when the first clamping block 76 is inserted into the corresponding slot 752, the receiving hole 751 corresponding to the slot 752 is positioned below the rotor unloading device 6, so as to facilitate the transfer of the rotor to the receiving hole 751. Exemplarily, the rotor fixture 75 is provided with a first receiving hole 751, a second receiving hole 751, a third receiving hole 751 and a fourth receiving hole 751. The first clamping slots 752 and the fourth clamping slots 752 are respectively provided on the side of the rotor fixture 75 corresponding to the first receiving hole 751-the fourth receiving hole 751. During the rotor unloading process, when the first clamping block 76 is driven to insert into the first clamping slot 752, the first receiving hole 751 corresponds to the rotor unloading device 6 provided above. The rotor unloading device 6 can grab the rotor on the support mold 22 for transfer and unloading; after the rotor in the first receiving hole 751 is placed, the first clamping block 76 can exit the first clamping groove 752, and the rotor fixture 75 continues to move under the conveyance of the second conveyor belt 721, and further the first clamping block 76 can be clamped into the second clamping groove 752 so that the second receiving hole 751 corresponds to the rotor unloading device 6 arranged above, and the rotor unloading device 6 can continue to grab the rotor unloading on the support mold 22 and transfer it to the second receiving hole 751. Therefore, based on the cooperation of the first clamping block 76 and the clamping groove 752, the receiving hole 751 on the rotor fixture 75 can be made to correspond to the rotor unloading device 6 above in turn, and the transfer and unloading of the rotor can be completed based on the rotor feeding device 3.

[0095] In some embodiments, a proximity sensor (not shown in the drawings) is movably provided on one side of the second conveyor belt 721 corresponding to the rotor unloading device 6, and a sensing detection component adapted to the proximity sensor is provided on each receiving hole 751 provided on the rotor fixture 75. In this way, by providing a proximity sensor and correspondingly providing a sensing detection component on the rotor fixture 75, it is convenient to accurately insert the first clamping block 76 into the clamping slot 752 of the support mold 22, and the sensing detection component is a metal component.

[0096] In some embodiments, a material detector is provided on the side of the second conveyor belt 721 corresponding to the rotor unloading device 6, and the material detector is used to detect whether the rotor unloading device 6 has placed a rotor on the rotor fixture 75. In this way, after detecting that the rotor unloading transfer is completed, the system can control the first clamping block 76 to release the rotor fixture 75 to continue moving.

[0097] In some embodiments, a second clamping block (not shown in the drawings) is movably provided on one side of the first conveying belt 711, and each of the second clamping blocks is used to be clamped into the clamping slot 752 on the rotor jig 75, and a proximity sensor is adapted to the corresponding second clamping block. Furthermore, when the rotor jig 75 is conveyed on the first conveying belt 711, the conveying of the rotor jig 75 can be suspended based on the cooperation between the second clamping block and the clamping slot 752, so that the conveying pressure is buffered.

[0098] See also Fig.11 As shown, in some embodiments, the jig line changing mechanism 73 includes a docking plate 731, a push plate 732 and a position sensor; one end of the docking plate 731 is docked with the tail end of the first conveyor belt 711, and the other end is docked with the head end of the second conveyor belt 721; the push plate 732 is movably arranged to dock with the first conveyor belt 711, and is used to push the rotor jig 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 jig 75 is delivered in place.

[0099] In this embodiment, the docking plate 731 is arranged between the first conveyor belt 711 and the second conveyor belt 721. When the push plate 732 pushes the rotor jig 75, the rotor jig 75 moves on the docking plate 731 to be transferred 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 with the tail end of the first conveyor belt 711. When the rotor jig 75 is transported along the first conveyor belt 711, the rotor jig 75 can be limited in the angle space formed by the first plate body 7321 and the second plate body 7322. In this way, on the one hand, the rotor jig 75 is prevented from being separated from the first conveyor belt 711, and on the other hand, the stability of the rotor jig 75 when the push plate 732 pushes the rotor jig 75 can be improved.

[0100] See also Fig.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 head end of the first conveyor belt 711 and the tail end of the second conveyor belt 721; the pushing assembly 742 is arranged on one side of the table 741 close to the second conveyor belt 721, and is used to push the rotor fixture 75 on the table 741 that is transported by the second conveyor belt 721 to the other side of the table 741.

[0101] In this embodiment, the pusher assembly 742 can be provided to clean the table 741 in time, so that the second conveyor belt 721 can continue to convey the rotor fixture 75 to the table 741 ; and on the other side of the table 741 , the operator can transfer the rotor on the rotor fixture 75 .

[0102] Specifically, the pushing assembly 742 includes a pushing driving member 7421 and a jig pushing plate 7422 ; the jig pushing plate 7422 is connected to the output end of the pushing driving member 7421 , and is used to push the rotor jig 75 to move under the drive of the pushing driving member 7421 .
