[0043] 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.

[0044] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0045] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0046] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. 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.

[0047] See also Figure 1 As shown, the present application discloses a motor assembly device 100. The motor assembly device 100 includes a frame 1, a turntable assembly 2 rotatably arranged on the frame 1, and a large shell feeding device 3, a rotor assembly device 4, a centering oil feeding device 5, a rubber cover assembly device 6, a motor riveting device 7, a shaft-out and virtual position detection device 8, a flipping device 9 and a blanking test device 10 arranged on the frame 1 in sequence around the turntable assembly 2; the turntable assembly 2 includes a turntable body 21 and a plurality of molds 22 for magnetically attracting large shells movably arranged on the circumference of the turntable body 21; the turntable assembly 2 can drive the mold 22 to sequentially dock with the large shell feeding device 3, the rotor assembly device 4, the centering oil feeding device 5, the rubber cover assembly device 6, the motor riveting device 7, the shaft-out and virtual position detection device 8, the flipping device 9 and the blanking test device 10.

[0048] The technical solution of the present application, such as the large shell feeding device 3, the rotor assembly device 4, the centering oil feeding device 5, the rubber cover assembly device 6, etc., which are arranged around the turntable assembly 2, are a corresponding processing station. Based on the above structural setting, after the large shell is loaded onto the support mold 22, it can follow the turntable body 21 to move to the corresponding station of each device to perform corresponding operations, and complete the assembly between the large shell and the rotor, the assembly between the rubber cover and the large shell, and other operation steps in sequence, with a high degree of automation integration, which can improve the motor assembly efficiency and stabilize the assembly quality.

[0049] See also Figure 2 As shown, in some embodiments, the mold 22 includes a fixed seat 221, a magnetic portion 222 and an elastic return member 223; the fixed seat 221 is installed on the turntable body 21; the magnetic portion 222 is slidably connected to the fixed seat 221 in the vertical direction, and a fitting groove is formed on the magnetic portion 222 to fit the outer periphery of the rotor; one end of the elastic return member 223 is connected to the fixed seat 221, and the other end is connected to the magnetic portion 222.

[0050] In this embodiment, the magnetic attraction part 222 is slidably arranged in the vertical direction, and its purpose is to cooperate with the device in the subsequent workstation to realize the installation of the rotor or the rubber cover and other operations. For example, when installing the rotor or the rubber cover, it is necessary to press down the large shell to move the magnetic attraction part 222 downward. Among them, the fitting groove formed by the magnetic attraction part 222 can facilitate the installation of the large shell and the subsequent pick-up and placement operations of the large shell. When the magnetic attraction part 222 moves downward, it can drive the elastic return part 223 to undergo elastic deformation. After the assembly of the rotor and the rubber cover is completed, the elastic return part 223 will drive the magnetic attraction part 222 to reset under the action of its own elastic force.

[0051] The elastic restoring member 223 may be a telescopic spring. Two groups of the telescopic springs are provided on both sides of the magnetic attraction portion 222 to form a stable elastic restoring force.

[0052] See also Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the large shell feeding device 3 includes a large shell feeding and conveying mechanism 31, a large shell direction adjustment mechanism 32 and a large shell grabbing and moving mechanism 33; the large shell feeding and conveying mechanism 31 includes a large shell feeding and conveying line, one end of the large shell feeding and conveying line is a feeding end; the large shell direction adjustment mechanism 32 includes a mounting seat 321 and a rotating drive assembly arranged on the mounting seat 321, and the mounting seat 321 is connected to the discharge end of the large shell feeding and conveying line; wherein the rotating drive assembly is used to drive the large shell to rotate after the large shell enters the mounting seat 321 to adjust the direction of the large shell; the large shell grabbing and moving mechanism 33 is arranged between the large shell direction adjustment mechanism 32 and the backing mold 22, and is used to transfer the large shell on the large shell direction adjustment mechanism 32 to the backing mold 22.

[0053] In this embodiment, the large shell feeding conveyor line can be a large shell belt conveyor line, and limit baffles 311 are arranged on both sides of the large shell belt conveyor line along the conveying direction of the large shell belt conveyor line. The material is discharged onto the large shell belt conveyor line by manual or automatic loading, and the large shell is conveyed along the large shell belt conveyor line between the limit baffles 311.

[0054] It can be understood that there is a deviation between the direction of the large shell feeding and conveying and the positioning direction of the backing mold 22. Therefore, it is necessary to drive the large shell to rotate through the large shell direction adjustment mechanism 32 to adjust the direction of the large shell, and further after the direction adjustment is completed, the large shell is grasped and moved by the large shell grabbing and moving mechanism 33 to be transferred to the backing mold 22 for fixing. Among them, the large shell grabbing and moving mechanism 33 includes a combined design of a moving component + a grabbing component, which is a conventional setting for those skilled in the art and will not be repeated here.

[0055] See also Figure 4 As shown, in some embodiments, a rotation groove 322 is formed at the top of the mounting seat 321; the rotation drive assembly includes a rotation head 323 and a rotation drive member 324; the rotation head 323 is docked in the rotation groove 322, and is used to support and clamp the large shell after the large shell enters the rotation groove 322; the rotation drive member 324 is connected to the rotation head 323, and is used to drive the rotation head 323 to rotate.

[0056] In this embodiment, the large shell enters the large shell direction adjustment mechanism 32, that is, enters the rotating groove 322. In fact, the rotating groove 322 is formed between the rotating head 323 and the mounting seat 321. When the large shell enters the rotating groove 322, a connection can be established with the rotating head 323. Further, in the process of the rotating driving member 324 driving the rotating head 323 to rotate, the rotating head 323 drives the large shell to rotate to adjust the direction of the large shell.

[0057] See also Figure 4 As shown, in some embodiments, the rotating head 323 includes a supporting base 3232 and a clamping block 3231 ; the supporting base 3232 is connected to the rotating driving member 324 ; two clamping blocks 3231 are provided, and the two clamping blocks 3231 are provided on opposite sides of the supporting base 3232 .

[0058] The cross-sectional structure of the large shell includes two opposite long straight sides and two opposite short sides, and the short sides are usually designed as arcs. In this embodiment, the rotating head 323 includes a supporting base 3232 and a clamping block 3231. The supporting base 3232 can support the large shell when the large shell enters the rotating groove 322. At this time, the two oppositely arranged clamping blocks 3231 can be respectively clamped on the outer sides of the side surfaces corresponding to the two long straight sides of the large shell. When the rotating head 323 rotates, the clamping blocks 3231 abut against the side surfaces of the large shell to drive the large shell to rotate.

[0059] See also Figure 4As shown, in some embodiments, the rotating drive member 324 includes a rotating shaft 3241 and a rotating driver 3242; one end of the rotating shaft 3241 is connected to the supporting base 3232, and the other end is fixedly connected to a driven wheel; the output end of the rotating driver 3242 is fixedly connected to a driving wheel, and the driving wheel and the driven wheel are connected by a transmission belt.

[0060] In this embodiment, the rotary driver 3242 is used as a power output, and power transmission is achieved through the driving wheel, the driven wheel, and the transmission belt between the driving wheel and the driven wheel. The design of the rotary driver 324 has the advantages of being simple and efficient, easy to maintain, buffering and shock absorbing, flexible adjustment, and suitable for long-distance transmission. It can provide reliable power support for the rotation of the rotary head 323.

[0061] See also Figure 4 As shown, in some embodiments, a feed docking port 325 is provided on one side of the rotating container 322 close to the large shell feed conveyor line, and the bottom surface of the feed docking port 325 is flush with the top of the supporting base 3232 .

[0062] In this embodiment, a feed docking port 325 is provided on one side of the rotating tank 322, and the large shells conveyed by the large shell feeding conveyor line can enter the rotating tank 322 through the feed docking port 325. When the bottom surface of the feed docking port 325 is flush with the top of the supporting base 3232, it is convenient for the large shells to transition from the feed docking port 325 to the supporting base 3232.

[0063] Further, the feed docking port 325 is a trumpet-shaped inlet. In this way, it is convenient for the large shells transported by the large shell feeding conveying line to enter the feed docking port 325.

[0064] See also Figure 4 As shown, in some embodiments, a sensor detector 326 is provided on the mounting seat 321 to dock with the rotating groove 322. The sensor detector 326 is used to detect whether the large shell is placed in place. The clamping block 3231 is provided with an avoidance hole 3233 to avoid the detection path of the sensor detector 326.

[0065] It is understandable that the large shell needs to be placed on the mold 22 in a predetermined direction, so as to facilitate the assembly of the large shell and the rubber cover in the subsequent workstation. Among them, the long straight side of the large shell is provided with a docking notch, and the sensor detector 326 adjusts the rotation of the large shell to a predetermined direction after detecting the docking notch. Exemplarily, the sensor detector 326 is correspondingly arranged on the left side of the rotation accommodating groove. When the docking notch is detected, the large shell continues to rotate until the docking notch is moved to the side away from the mold 22, and then when the large shell is transferred and fixed to the mold 22, the docking notch is relatively located on the outside.

[0066] When the large shell is placed in the rotating groove, the clamping block 3231 on the rotating head 323 is relatively arranged on the outer side of the side corresponding to the long straight side of the large shell. At this time, the clamping block 3231 forms an obstruction to the detection path of the sensor detector 326. Therefore, an avoidance hole 3233 is opened on the clamping block 3231 to avoid the sensor detector 326 from detecting the docking gap.

[0067] In some embodiments, a magnetic pole detection station (not shown in the drawings) is provided between the large shell feeding device 3 and the rotor assembly device 4, and a magnetic pole detection device is provided at the station to detect whether the magnet in the large shell is installed correctly.

[0068] See also Figure 5 As shown, in some embodiments, the rotor assembly device 4 includes a rotor feeding mechanism 41, a positioning assembly 43, a rotor grabbing and moving mechanism 42 and a large shell pressing mechanism 44; the rotor feeding mechanism 41 includes a rotor feeding conveyor line 411, which is used for conveying and feeding the rotor; the positioning assembly 43 is used to position the rotor; the rotor grabbing and moving mechanism 42 is arranged between the rotor feeding mechanism 41 and the positioning assembly 43, and is used to transfer the rotor on the rotor feeding conveyor line 411 to the positioning assembly 43; the large shell pressing mechanism 44 is correspondingly arranged above the positioning assembly 43, and is used to cooperate with the positioning assembly 43 to press the rotor into the large shell.

[0069] In this embodiment, the rotor can be directly fed to the rotor feeding conveyor line 411 after being processed by the previous processing equipment. The rotor grabbing moving mechanism 42 grabs the rotor on the rotor feeding conveyor line 411 and transfers it to the positioning component 43 for positioning, wherein the rotor grabbing moving mechanism 42 can also be a combination design of a moving component + a grabbing component, which is a conventional setting for those skilled in the art and will not be described in detail.

[0070] Before pressing, the large shell fixed on the mold 22 can be transferred to between the positioning assembly 43 and the large shell pressing mechanism 44 by following the movement of the turntable assembly 2, and then the large shell can be driven downward by the downward pressure of the large shell pressing mechanism 44, and finally the rotor can enter the large shell in cooperation with the positioning assembly 43 to complete the assembly between the large shell and the rotor.

[0071] See also Figure 6 As shown, in some embodiments, the rotor is placed on a rotor fixture 40 for transportation; the rotor loading conveyor line 411 includes a rotor belt conveyor line, and a material blocking mechanism is provided at the other end of the rotor belt conveyor line, and the material blocking mechanism is used to position the rotor fixture 40.

[0072] In this embodiment, the rotor is conveyed by a rotor belt conveyor line, and belt conveyor line conveying is a conventional conveying method in the art. The material blocking mechanism is arranged at the other end of the rotor belt conveyor line, i.e., the tail end. When the rotor fixture 40 is positioned by the material blocking mechanism, the rotor on the rotor fixture 40 can be positioned, thereby facilitating the rotor grabbing moving mechanism 42 to grab.

[0073] See also Figure 6 As shown, in some embodiments, a plurality of accommodating holes 401 are opened on the rotor jig 40 along the conveying direction of the rotor belt conveyor line, and a card slot 402 is opened on both sides of the rotor jig 40 corresponding to each accommodating hole 401; the material blocking mechanism includes a card block 412 movably arranged on the side of the rotor belt conveyor line, and the card block 412 is used to be inserted into the card slot 402 to position the rotor jig 40.

[0074] It can be understood that the slots 402 are opened corresponding to the receiving holes 401. During the rotor conveying process, when the block 412 is inserted into the corresponding slot 402, the rotor in the receiving hole corresponding to the slot 402 is positioned at a fixed position for the rotor grabbing and moving mechanism 42 to grab. Exemplarily, the rotor jig 40 is provided with a first receiving hole 401, a second receiving hole 401, a third receiving hole 401 and a fourth receiving hole 401, and corresponding to the first receiving hole 401-the fourth receiving hole 401, a first clamping groove 402-a fourth clamping groove 402 are respectively provided on the side of the rotor jig 40. When the clamping block 412 is driven to be clamped into the first clamping groove 402 during the rotor conveying process, the rotor in the first receiving hole 401 is positioned at a fixed position, and the rotor grabbing and moving mechanism 42 can grab the rotor in the first receiving hole 401 for transfer and loading; after completing the transfer of the rotor in the first receiving hole 401, the clamping block 412 can withdraw from the first clamping groove 402, the rotor jig 40 continues to move, and further the clamping block 412 can be clamped into the second clamping groove 402 so that the rotor in the second receiving hole 401 is positioned at a fixed position, and the rotor grabbing and moving mechanism 42 can grab the rotor in the second receiving hole 401 for transfer and loading. Therefore, based on the cooperation between the clamping block 412 and the clamping slot 402 , the rotor on the rotor fixture 40 can be positioned to a fixed position in turn, and the rotor can be transferred and loaded onto the positioning assembly 43 based on the rotor grabbing and moving mechanism 42 .

[0075] See also Figure 7 as well as Figure 8As shown, in some embodiments, the positioning assembly 43 includes a positioning seat 431, a first clamping block 433 and a second clamping block 432; a rotor placement position 4311 is provided on the top of the positioning seat 431, and a receiving cavity is provided inside the positioning seat 431; the first clamping block 433 is fixedly provided in the receiving cavity; the second clamping block 432 is movable and arranged opposite to the first clamping block 433, and the second clamping block 432 can move toward or away from the first clamping block 433; wherein, when the rotor is placed on the rotor placement position 4311, the rotating shaft in the rotor is inserted into the receiving cavity, and the first clamping block 433 and the second clamping block 432 move toward each other to clamp and fix the rotating shaft of the rotor.

[0076] In this embodiment, before the rotor is placed in the rotor placement position 4311, the first clamp block 433 and the second clamp block 432 are separated, and the rotor can be initially positioned when the rotor is placed in the rotor placement position 4311. A corresponding detector can be provided to detect whether the rotor is placed on the positioning seat 431, and after the detection, the system drives the second clamp block 432 to move relative to the first clamp block 433, and the first clamp block 433 and the second clamp block 432 cooperate to clamp and fix the rotating shaft inserted into the accommodating cavity in the rotor, thereby fixing the rotor.

[0077] Furthermore, a first clamping groove is formed on one side of the first clamping block 433 close to the second clamping block 432, and a second clamping groove is formed on one side of the second clamping block 432 close to the first clamping groove, and the rotating shaft in the rotor is clamped and fixed between the first clamping groove and the second clamping groove. In this way, the clamping and fixing effect of the rotating shaft in the rotor can be improved.

[0078] See also Fig. 9 As shown, in some embodiments, the large shell pressing mechanism 44 includes a rotor assembly press head 441. The rotor assembly press head 441 is fixedly connected to a sliding block 442, and is movably arranged above the rotor placement position 4311. The rotor assembly press head 441 can move in the vertical direction following the sliding block 442, and the rotor assembly press head 441 is used to press down the large shell so that the rotor relatively enters the large shell.

[0079] In this embodiment, the rotor assembly press head 441 moves with the sliding block 442. During the pressing process, it can squeeze the large shell on the mold 22 and drive the large shell and the magnetic attraction part 222 to move downward until the large shell is pressed down to a predetermined position, completing the assembly between the rotors.

[0080] After the large shell is pressed down to a predetermined position, it is first necessary to remove the clamping of the rotor by the first clamp 433 and the second clamp 432 so that the large shell can drive the rotor to move together during the automatic recovery process of the magnetic attraction portion 222 .

[0081] See also Fig. 9As shown, in some embodiments, the rotor assembly press head 441 includes a first pressing portion 4411 and a second pressing portion 4412; the first pressing portion 4411 is used to press down the large shell; the second pressing portion 4412 is attached to the first pressing portion 4411 and is arranged on the outer side of the first pressing portion 4411. The second pressing portion 4412 is longer in length extending downward relative to the first pressing portion 4411, and the second pressing portion 4412 is used to press down the magnetic attraction portion 222.

[0082] In this embodiment, when the second pressing part 4412 extends downwardly longer than the first pressing part 4411, a pressing step is constructed between the first pressing part 4411 and the second pressing part 4412, and a pressing height difference is formed. This design enables the first pressing part 4411 to first press down to the top of the large shell during the downward pressing process of the rotor assembly ram 441, and in the continued downward pressing action, the first pressing part 4411 can drive the large shell to move downward relative to the magnetic part 222 until the second pressing part 4412 presses down onto the magnetic part 222, driving the magnetic part 222 and the large shell to be pressed down together. In this process, the position of the large shell can be adjusted to drive the large shell and the magnetic part 222 to have a unified standard relative position relationship, wherein the distance between the top of the large shell and the top of the magnetic part 222 is the pressing height difference formed between the first pressing part 4411 and the second pressing part 4412.

[0083] See also Fig. 9 As shown, in some embodiments, the rotor assembly pressing head 441 is provided with a through hole along its length direction; the large shell pressing mechanism 44 also includes a guide pin 443, the guide pin 443 is arranged to pass through the through hole, and the guide pin 443 can move in the vertical direction.

[0084] In this embodiment, the guide pin 443 needs to be inserted into the through hole before pressing down the rotor assembly pressure head 441. On the one hand, it can guide the position adjustment of the large shell to prevent the large shell from detaching during the movement; on the other hand, it can pre-dock with the rotating shaft of the rotor positioned by the positioning assembly 43 below to provide pressing accuracy.

[0085] See also Fig. 9 As shown, in some embodiments, the large shell pressing mechanism 44 further includes a movably arranged limit member 444, and the limit member 444 is arranged below the sliding block 442; wherein the moving path of the limit member 444 includes a first limit point position and a second limit point position.

[0086] In this embodiment, the limiter 444 is set corresponding to the sliding block 442, and when the first limiter position and the second limiter position are set on the moving path of the limiter 444, the rotor assembly pressure head 441 connected to the sliding block 442 can be pressed down and assembled in two steps. Specifically, the height of the first limiter position is higher than the height of the second limiter position. The limiter 444 is first located at the first limiter position. During the pressing process of the rotor assembly pressure head 441, the limiter 444 blocks the sliding block 442 at the first limiter position, so that the rotor assembly pressure head 441 can only be pressed down and moved a distance, which can make the guide pin 443 dock with the rotating shaft on the rotor; then the limiter 444 moves to the second limiter position, and the sliding block 442 continues to drive the rotor assembly pressure head 441 to move downward under the drive, and the large shell moves into place to complete the assembly with the rotor.

[0088] In this embodiment, the oiling mechanism 51 is used to add lubricating oil, which can reduce the friction between the rotor and the large shell. When oiling is needed, the oiling head 511 moves toward the mold 22, and the oiling mechanism 51 operates to discharge oil, and the amount of oil is 1 to 2 drops; then, the oiling head 511 retracts, and after the retraction, the oiling head 511 is facing the waste oil recovery box 52 below, and some of the missed waste oil can drip into the waste oil recovery box 52 for recovery.

[0089] See also Fig.11 As shown, in some embodiments, the rubber cover assembly device 6 includes a rubber cover feeding and conveying mechanism 61, a rubber cover direction adjustment mechanism 63, a rubber cover grabbing and moving mechanism 62 and a rubber cover assembly pressure head 64; the rubber cover feeding and conveying mechanism 61 includes a rubber cover feeding and conveying line, which is used for conveying and feeding the rubber cover; the rubber cover direction adjustment mechanism 63 is used to adjust the direction of the rubber cover; the rubber cover grabbing and moving mechanism 62 is arranged between the rubber cover feeding and conveying mechanism 61 and the rubber cover direction adjustment mechanism 63, and is used to grab the rubber cover on the rubber cover feeding and conveying line and transfer it to the rubber cover direction adjustment mechanism 63; the rubber cover assembly pressure head 64 is arranged above the rubber cover direction adjustment mechanism 63, and is used to press down the large shell to complete the assembly with the rubber cover.

[0090] In this embodiment, the rubber cover feeding and conveying mechanism 61 includes a rubber cover belt conveyor line, which is a conventional belt conveyor structure. The rubber covers are fed manually or automatically. The rubber cover grabbing and moving mechanism 62 grabs the rubber covers on the rubber cover belt conveyor line and transfers them to the rubber cover direction adjustment mechanism 63 for positioning and direction adjustment.

[0091] Before pressing, the large shell fixed on the mold 22 can be transferred to between the rubber cover direction adjustment mechanism 63 and the rubber cover assembly pressure head 64 following the movement of the turntable assembly 2, and then under the downward pressure drive of the rubber cover assembly pressure head 64, the large shell can be driven to move downward, and finally, with the cooperation of the rubber cover direction adjustment mechanism 63, the assembly between the large shell and the rubber cover is completed.

[0092] See also Fig.12 As shown, in some embodiments, the rubber cover grabbing moving mechanism 62 includes a synchronously moving carbon brush separator block 621 and a rubber cover grabbing manipulator 622, the carbon brush separator block 621 is relatively arranged above the rubber cover grabbing manipulator 622; the carbon brush separator block 621 is used to separate the carbon brushes on the rubber cover, and the rubber cover grabbing manipulator 622 is used to grab the rubber cover;

[0093] It can be understood that two carbon brushes are relatively fixed in the rubber cover by two springs, and the two carbon brushes need to be separated in advance during the assembly of the rubber cover. Therefore, the rubber cover grabbing and moving mechanism 62 provided in this embodiment completes the relevant operations through the carbon brush separation block 621 and the rubber cover grabbing manipulator 622. Among them, the carbon brush separation block 621 and the rubber cover can be synchronously moved between the rubber cover belt conveyor line and the rubber cover direction adjustment mechanism 63 to complete the transfer of the rubber cover.

[0094] A transfer process of a rubber cover grabbing and moving mechanism 62 grabbing the rubber cover includes: the rubber cover grabbing manipulator 622 is pre-opened, and when docking with the rubber cover on the rubber cover belt conveyor line below, the grabbing manipulator and the rubber cover separator block move downward synchronously. During this process, the rubber cover separator block squeezes the two spring sheets from the middle to separate them on both sides, that is, squeezes and separates the carbon brushes, and after squeezing into place, the grabbing manipulator clamps the rubber cover, further drives the grabbing manipulator to grab the rubber cover, and the grabbing manipulator moves synchronously with the rubber cover separator block to transfer the rubber cover to the rubber cover direction adjustment mechanism 63.

[0095] Among them, the lower end of the rubber cover separator block is similar to a U-shaped structure, which is convenient for squeezing and separating the two spring sheets.

[0096] See also Fig.14 as well as Fig.15As shown, in some embodiments, the rubber cover direction adjustment mechanism 63 includes a connecting seat 631, a placement seat 632 and a supporting assembly 634; the connecting seat 631 is movably arranged, and the connecting seat 631 can move in a direction toward or away from the backing mold 22; the placement seat 632 is rotatably arranged on the connecting seat 631, and a rubber cover storage position is arranged on the top of the placement seat 632; wherein, the placement seat 632 is connected to a transmission assembly 633; ​​the supporting assembly 634 is arranged close to the turntable assembly 2 and docking with the transmission assembly 633; ​​wherein, when the connecting seat 631 moves toward the backing mold 22, the transmission assembly 633 contacts the supporting assembly 634, and when the connecting seat 631 continues to move toward the backing mold 22, the supporting assembly 634 abuts against the transmission assembly 633 to drive the placement seat 632 to rotate.

[0097] In this embodiment, the rubber cover is placed on the rubber cover storage position of the placement seat 632. When the connection seat 631 moves toward the backing mold 22, the placement seat 632 can be driven to move toward the backing mold 22. When the movement is in place, the rubber cover on the placement seat 632 is directly opposite to the lower part of the rubber cover assembly pressure head 64. When the movement is in place, based on the cooperation between the abutting component 634 and the transmission component 633, the placement seat 632 can be driven to drive the rubber cover thereon to rotate, so that the rubber cover corresponds to the orientation of the large shell. In this way, the rubber cover is moved to the right position and the direction of the rubber cover is changed at the same time.

[0098] See also Fig.14 as well as Fig.15 As shown, in some embodiments, a first limiting rod 6322 and a second limiting rod 6323 are vertically disposed on the top of the placement seat 632, and the first limiting rod 6322 and the second limiting rod 6323 are used to limit the carbon brush in the rubber cover placed in the rubber cover storage position.

[0099] In this embodiment, the purpose of providing the first limiting rod 6322 and the second limiting rod 6323 is to keep the carbon brushes in the rubber cover in a separated state when the rubber cover is placed on the rubber cover placement position 6321. Specifically, the first limiting rod 6322 and the second limiting rod 6323 can pass through the rubber cover and block the rebound path of the spring pieces corresponding to the two carbon brushes to prevent the carbon brushes from rebounding.

[0100] See also Fig.14 as well as Fig.15 As shown, in some embodiments, the transmission assembly 633 includes a transmission rod 6331 ; the transmission rod 6331 passes through the placement seat 632 and is fixedly connected to the placement seat 632 , and one end of the transmission rod 6331 is butted against the assembly 634 .

[0101] In this embodiment, a process of driving the mounting seat 321 to rotate through the cooperation between the transmission component 633 and the abutment component 634 is as follows: when the placement seat 632 follows the connecting seat 631 to move toward the support mold 22, one end of the transmission rod 6331 will gradually approach the abutment component 634 and be blocked by the abutment component 634. Under the reaction force, the transmission rod 6331 will push the placement seat 632 to rotate, thereby driving the rubber cover placed thereon to rotate, thereby achieving the purpose of adjusting the direction of the rubber cover.

[0102] See also Fig.14 as well as Fig.15 As shown, in some embodiments, the transmission assembly 633 also includes an elastic telescopic member 6332 and a return limit rod 6333, one end of the elastic telescopic member 6332 is connected to the other end of the transmission rod 6331, and the other end is fixed on the connecting seat 631; the return limit rod 6333 is fixedly connected to the placement seat 632, and the connecting seat 631 is provided with a contact fastener 6311 corresponding to the return limit rod 6333.

[0103] Furthermore, when the transmission rod 6331 moves, the elastic member 6332 can be deformed, so that after the placement seat 632 follows the connection seat 631 away from the backing mold 22, the placement seat 632 is driven by the elastic member 6332 to return to the initial state, so that the rubber cover grabbing and moving mechanism 62 can continue to grab the rubber cover and transfer it to the placement seat 632. Among them, through the cooperation between the return limit rod 6333 and the abutment fast 6311, the placement seat 632 can be returned to the initial position every time.

[0104] Furthermore, the elastic telescopic member 6332 is a telescopic spring, and when the abutting assembly 634 presses the driving transmission rod 6331, the telescopic spring is stretched. In this way, it is relatively easy to set up the relevant structure.

[0105] See also Fig.14 as well as Fig.15 As shown, in some embodiments, the abutment assembly 634 includes a abutment plate 6341 and abutment member 6342; the abutment member 6342 is movably mounted on the abutment plate 6341 and is arranged corresponding to one end of the transmission rod 6331; wherein the abutment member 6342 can move in a direction toward the transmission rod 6331.

[0106] In this embodiment, the abutment member 6342 is movably arranged, and the rotation angle of the placement seat 632 can be adjusted. When the abutment member 6342 extends more relative to the abutment plate 6341 and the placement seat 632 moves into position following the connection seat 631, the rotation angle of the placement seat 632 is larger; and when the abutment member 6342 extends less relative to the abutment plate 6341 and the placement seat 632 moves into position following the connection seat 631, the rotation angle of the placement seat 632 is smaller. The user can make adjustments based on the actual situation and on the premise that the rubber cover can correspond to the orientation of the large shell.

[0107] In some embodiments, the abutment member 6342 is a screw, which is threadedly connected to the abutment plate 6341. In this way, the extension length of the abutment member 6342 relative to the abutment plate 6341 can be adjusted by twisting, making the adjustment more convenient and quick.

[0108] See also Fig.13 As shown, in some embodiments, the rubber cover assembly pressure head 64 includes a first pressing block 641 and a second pressing block 642; the first pressing block 641 is used to press down the large shell; the second pressing block 642 is attached to the first pressing block 641 and is arranged on the outside of the first pressing block 641. The second pressing block 642 is longer than the first pressing block 641 in extending downward, and the second pressing block 642 is used to press down the magnetic attraction part 222.

[0109] In this embodiment, when the second pressing block 642 extends downward longer than the first pressing block 641, a pressing step is constructed between the first pressing block 641 and the second pressing block 642, and a pressing height difference is formed. This design enables the first pressing block 641 to first press down to the top of the large shell during the downward pressing process of the rubber cover assembly press head 64, and in the continued downward pressing action, the first pressing block 641 can drive the large shell to move downward relative to the magnetic attraction part 222 until the second pressing block 642 presses down onto the magnetic attraction part 222, driving the magnetic attraction part 222 and the large shell to be pressed down together. In this process, the position of the large shell can be adjusted to drive the large shell and the magnetic attraction part 222 to a unified standard relative position relationship, wherein the distance between the top of the large shell and the top of the magnetic attraction part 222 is the pressing height difference formed between the first pressing block 641 and the second pressing block 642.

[0110] See also Fig.16 As shown, in some embodiments, the motor riveting device 7 includes a riveting lower die column 71 and a riveting head 72; the riveting lower die column 71 includes a column and a riveting pressing part 73 arranged on the top circumference of the column; the riveting head 72 is relatively arranged above the riveting lower die column 71, and the riveting head 72 is used to press down the large shell so that the large shell forms a protrusion embedded in the rubber cover under the pressure of the riveting pressing part 73.

[0111] After the assembly between the large shell and the rotor and the rubber cover is completed, the motor is assembled. The above steps only allow the rubber cover to be inserted into the large shell through the tight fit between the structures, and there is a risk of separation between the rubber cover and the large shell. It should be noted that the rubber cover itself is designed with an embedding groove. Under the pressure of the riveting and pressing part 73, the large shell is deformed, and the protrusion generated by the deformation is embedded in the embedding groove.

[0112] In this embodiment, a large shell riveting structure is provided, so that the large shell forms an inwardly convex protrusion on its side wall under the cooperation of the riveting head 72 and the riveting pressing piece 73, so that the rubber cover and the large shell are more tightly combined.

[0114] Among them, multiple riveting and pressing parts 73 are arranged around the seat 711, and arc steps are formed on the side of the riveting and pressing parts 73 close to the seat 711. Multiple riveting and pressing parts 73 can form multiple inwardly convex protrusions on the peripheral side of the motor, thereby increasing the number of connection points between the rubber cover and the large shell and making the assembly tighter. It can be understood that after the arc steps are formed on the side of the riveting and pressing parts 73 close to the seat 711, in the process of the riveting and pressing head 72 driving the large shell to press down, the lower end of the large shell will gradually be pressed to fit the shape of the arc steps, that is, a protrusion will be formed inward.

[0115] In some embodiments, a press fitting installation position is formed on the column, and the riveted press fitting 73 is embedded in the press fitting installation position and locked with the column. The press fitting installation position is formed on the side of the column, and when the riveted press fitting 73 is embedded in the press fitting installation position, the left and right and up and down movement of the riveted press fitting 73 can be limited, and the riveted press fitting 73 can be further locked at the bottom of the side opposite to the press fitting installation position by screws to form a more stable connection.

[0117] In this embodiment, the riveting press head 72 is designed as a detachable riveting upper die column 721 and a press head pressing block 722, thereby enhancing the replaceability of the riveting upper die column 721 and the press head pressing block 722, and facilitating replacement when they are damaged.

[0118] The upper riveting die column 721 and the pressing head block 722 are locked by machine screws, or the upper riveting die column 721 and the pressing head block 722 are locked by threads.

In this way, during the process of the riveting pressure head 72 pressing down, the rotor exposed relative to the large shell can be inserted into the plug hole 7221, thereby stabilizing the pressing process of the large shell.

[0120] The entrance of the plug hole 7221 is in the shape of a trumpet, which can facilitate the relative insertion of the rotor with the exposed large shell into the riveting press head 72 .

[0121] In some embodiments, the riveting press head 72 is connected to a guide mechanism, which is used to guide the riveting press head 72 when it moves in the vertical direction. In this way, the guiding operation is achieved through the guide mechanism, and the downward pressing operation of the riveting press head 72 can be stabilized.

[0122] See also Fig.16 As shown, further, the guide mechanism includes a guide column 741 that is vertically movably arranged, and the riveting head 72 is connected to the guide column 741 through a connecting plate 742.

[0123] In some embodiments, the shaft extension and virtual position detection device 8 includes a detection base and a detection pressure head; the detection base is used to place the motor; the detection pressure head is used to press down the rotating shaft exposed relative to the large shell, so as to measure the extension amount of the rotating shaft relative to the large shell according to the downward pressure of the detection pressure head.

[0124] Motor shaft runout and clearance detection are important parts of motor quality control and performance evaluation. These tests help ensure the stability and reliability of the motor during operation, and also help predict the life and performance degradation of the motor. Motor shaft runout refers to the protruding length of the motor shaft or the position of the shaft end. The accuracy of shaft runout is critical to the installation and use of the motor. If the shaft runout is too long, it may cause installation difficulties or interference with other components; if the shaft runout is too short, it may not be possible to properly connect or fix the required components. Clearance usually refers to the looseness or clearance of the motor shaft when it is fixed or installed. Excessive clearance may cause unstable operation of the motor, generate vibration and noise, and even affect the performance and life of the motor.

[0125] This embodiment uses the shaft-out and virtual position detection device 8 to measure the performance of the assembled motor.
