Description

Technical Field

[0001] The present invention relates to the technical field of motor assembly, and particularly relates to an armature assembly device and an assembly method. Background Art

[0002] The armature is a component that plays a key and pivotal role in the process of converting mechanical energy and electrical energy in a motor. For a generator, it is the component that generates electromotive force. For example, the rotor in a DC generator. During the motor assembly process, the armature is usually assembled on the motor rear cover. The coaxiality between the armature and the motor rear cover has a great impact on the smooth operation of the motor. If the axis of the armature and the axis of the motor rear cover are offset, during the operation of the motor, it will cause shaking, affecting the stability and service life of the motor operation.

[0003] However, current motor assembly devices usually do not have a detection mechanism for detecting the coaxiality between the armature and the motor rear cover, or the detection accuracy is not high, and it is impossible to accurately calibrate the axes of the armature and the motor rear cover, resulting in low assembly quality of the armature and the motor rear cover, affecting the stability and service life of the motor. Moreover, the current motor assembly devices have low production efficiency. Summary of the Invention

[0004] The main object of the present invention is to provide an armature assembly device and an assembly method, aiming to improve the armature assembly quality and production efficiency.

[0005] To achieve the above object, the present invention provides an armature assembly device. The armature assembly device includes a frame, an armature loading mechanism, a motor rear cover loading mechanism, at least one group of armature brush opening mechanisms, and at least one group of armature axis calibration mechanisms for detecting the brush opening distance of the armature and detecting and calibrating the coaxiality between the armature and the motor rear cover. The armature loading mechanism and the motor rear cover loading mechanism are installed in parallel on both sides of the frame. At least one group of armature assembly stations is arranged on the frame along the movement direction of the motor rear cover loading mechanism. The armature brush opening mechanism is located between the armature assembly station and the armature loading mechanism. The armature axis calibration mechanism is located above the armature assembly station.

[0006] A further technical solution of the present invention is that the armature axis calibration mechanism includes a mounting mechanism mounted on the frame, a first manipulator, an armature detection camera for photographing the open brush distance of the armature and the axes of the armature and the motor rear cover, and a first driving mechanism for driving the first manipulator to move up and down, forward and backward. The armature detection camera is located directly above the assembly station. An axis calibration plate is mounted on the mounting mechanism. A buffer surface is provided on one side of the axis calibration plate close to the assembly station. One end of the first manipulator is used to clamp the armature, and the other end is in contact with the buffer surface and can move up and down, forward and backward relative to the buffer surface to drive the armature to move, so as to align the axis of the armature with the axis of the motor rear cover.

[0007] A further technical solution of the present invention is that the armature axis calibration mechanism further includes a second driving mechanism for driving the armature detection camera to move up and down to adjust the focal length.

[0008] A further technical solution of the present invention is that there are two sets of armature axis calibration mechanisms. The armature detection cameras of the two sets of armature axis calibration mechanisms are connected by a connecting piece. The connecting piece is horizontally movably mounted on the mounting mechanisms of the two sets of armature axis calibration mechanisms. The two sets of armature axis calibration mechanisms share the second driving mechanism to drive the connecting piece to move up and down to adjust the focal lengths of the armature detection cameras of the two sets of armature axis calibration mechanisms.

[0009] A further technical solution of the present invention is that the mounting mechanism includes a first mounting seat mounted on the frame and a second mounting seat mounted above the first mounting seat. A bracket is mounted on the second mounting seat. The axis calibration plate is mounted on the first mounting seat. The connecting piece is horizontally mounted on the brackets of the two sets of armature axis calibration mechanisms and moves up and down along the brackets under the drive of the second driving mechanism.

[0010] A further technical solution of the present invention is that the second driving mechanism includes a motor, a reducer and a lead screw mounted on the frame. The output end of the motor is connected to the input end of the reducer. The output end of the reducer is connected to the input end of the lead screw. The output end of the lead screw is connected to the connecting piece.

[0011] A further technical solution of the present invention is that the armature assembly equipment further includes a motor rear cover detection mechanism mounted on the frame at the entrance of the motor rear cover feeding mechanism and a finished product detection mechanism mounted on the frame at the exit of the motor rear cover feeding mechanism.

[0012] A further technical solution of the present invention is that the armature assembly equipment further includes a second manipulator mounted on the frame at a position corresponding to the finished product detection mechanism.

[0013] The beneficial effects of the armature assembly equipment of the present invention are as follows. Through the above technical solutions, the present invention includes a frame, an armature feeding mechanism, a motor rear cover feeding mechanism, at least one group of armature brush-opening mechanisms, and at least one group of armature axis calibration mechanisms for detecting the brush-opening distance of the armature and detecting and calibrating the coaxiality between the armature and the motor rear cover. The armature feeding mechanism and the motor rear cover feeding mechanism are installed in parallel on both sides of the frame. At least one group of armature assembly stations is arranged on the frame along the moving direction of the motor rear cover feeding mechanism. The armature brush-opening mechanism is located between the armature assembly station and the armature feeding mechanism. The armature axis calibration mechanism is located above the armature assembly station. Before assembling the armature, first detect whether the axis of the armature is aligned with the axis of the motor rear cover. If they are aligned, then install the armature into the motor rear cover, improving the assembly quality and working efficiency of the armature.

[0014] To achieve the above object, the present invention further provides an armature assembly method, which is applied to the armature assembly equipment as described above. The armature assembly equipment includes a motor rear cover feeding mechanism, an armature brush-opening mechanism, and an armature axis calibration mechanism. The method includes:

[0015] When the equipment is started, the motor rear cover feeding mechanism transports the motor rear cover to the assembly station, and the armature brush-opening mechanism brushes the armature and transports the brushed armature to the armature axis calibration mechanism.

[0016] The armature axis calibration mechanism detects the brush-opening distance of the armature and judges whether the brush-opening distance of the armature is qualified.

[0017] If the brush-opening distance of the armature is qualified, the armature axis calibration mechanism detects the coaxiality between the armature and the motor rear cover and judges whether the axes of the armature and the motor rear cover are aligned.

[0018] If the axes of the armature and the motor rear cover are aligned, then install the armature into the motor rear cover.

[0019] A further technical solution of the present invention is that the armature axis calibration mechanism includes an axis calibration plate, a first manipulator, and an armature detection camera. The steps for the armature axis calibration mechanism to detect the coaxiality between the armature and the motor rear cover and judge whether the axes of the armature and the motor rear cover are aligned include:

[0020] The first manipulator moves up and down, back and forth along the buffer surface of the axis calibration plate to drive the axis of the armature to move towards the axis of the motor rear cover, and the armature detection camera takes pictures of the armature and the motor rear cover to judge whether the axes of the armature and the motor rear cover are aligned.

[0021] The beneficial effect of the armature assembly method of the present invention is that through the above technical solution, when the equipment is started, the motor rear cover feeding mechanism transports the motor rear cover to the assembly station. The armature brush opening mechanism brushes the armature, and transports the brushed armature to the armature axis calibration mechanism. The armature axis calibration mechanism detects the brush opening distance of the armature to determine whether the armature brush opening distance is qualified. If the armature brush opening distance is qualified, the armature axis calibration mechanism detects the coaxiality between the armature and the motor rear cover to determine whether the axes of the armature and the motor rear cover are aligned. If the axes of the armature and the motor rear cover are aligned, the armature is installed into the motor rear cover, improving the assembly quality and working efficiency of the armature.

[0038] The realization of the object, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0040] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0041] In addition, if there are descriptions such as "first" and "second" in the embodiments of the present invention, the descriptions of "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution that satisfies both A and B at the same time. In addition, the technical solutions between the embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0042] Considering the current motor assembly equipment, there is usually no detection mechanism for detecting the coaxiality of the armature and the motor rear cover, or the detection accuracy is not high, and the accurate calibration of the axes of the armature and the motor rear cover cannot be achieved, resulting in low assembly quality of the armature and the motor rear cover, affecting the stability and service life of the motor. Moreover, the current motor assembly equipment has low production efficiency. Therefore, the present invention proposes an armature assembly equipment.

[0043] As Figures 1 to 3 shown, a preferred embodiment of the armature assembly equipment of the present invention includes a frame 10, an armature loading mechanism 20, a motor rear cover loading mechanism 30, at least one group of armature brush opening mechanisms 40, and at least one group of armature axis calibration mechanisms 50 for detecting the brush opening distance of the armature and detecting and calibrating the coaxiality of the armature and the motor rear cover.

[0044] Among them, the armature loading mechanism 20 and the motor rear cover loading mechanism 30 are installed in parallel on both sides of the frame 10. At least one group of armature assembly stations is arranged on the frame 10 along the movement direction of the motor rear cover loading mechanism 30. The armature brush opening mechanism 40 is located between the armature assembly station and the armature loading mechanism 20, and the armature axis calibration mechanism 50 is located above the armature assembly station.

[0045] After the equipment is started, the armature loading mechanism 20 drives the armature to move and transports the armature to the armature brush opening mechanism 40 for brush opening.

[0046] A fixing clamp for fixing the armature is provided at the armature brush opening mechanism 40. The fixing clamp is fixed and reset by a return spring at the bottom. When the return spring is pressed down, the top of the fixing clamp opens. When the return spring is released, the fixing clamp resets to fix the armature.

[0047] In this embodiment, different armature brush opening schemes can be adopted based on different types and models of armatures.

[0048] As an implementation scheme, as Figure 4 shown, the armature brush opening mechanism 40 includes fork levers 401 arranged on opposite sides of the armature brush opening station on the frame 10 according to the type and model of the armature. When brushing the armature, the two fork levers 401 are inserted into the armature relatively, and then the two fork levers 401 are forced in opposite directions to achieve the armature brush opening operation.

[0049] As another implementation scheme, two ejector pins can be arranged in parallel under the frame 10 according to the type and model of the armature. When brushing the armature, the two ejector pins are inserted into the armature upward, and then the two ejector pins are forced in opposite directions to achieve the armature brush opening operation.

[0050] In this embodiment, the armature brush-opening mechanism 40 is arranged between the armature assembly station and the armature loading mechanism 20, which is convenient for improving work efficiency.

[0051] As Figure 5 shown, in this embodiment, when transporting the armature to the armature brush-opening mechanism 40 or the armature axis calibration mechanism 50, it can be realized by the armature transporting manipulator 60. Specifically, an X-axis motion module 601 can be installed on the frame 10 between the armature assembly station and the armature loading mechanism 20, and then the armature transporting manipulator 60 is installed on the X-axis motion module 601.

[0052] After the armature brush-opening mechanism 40 brushes the armature, the armature is transported to the armature axis calibration mechanism 50 by the armature transporting manipulator 60. The armature axis calibration mechanism 50 detects the brush-opening distance of the armature. If the brush-opening distance meets the requirements and the detection result is qualified, it drives the armature to move towards the motor rear cover on the armature assembly station, and the armature axis calibration mechanism 50 detects whether the axis of the armature is aligned with the axis of the motor rear cover. If the axis of the armature is aligned with the axis of the motor rear cover, the armature is installed into the motor rear cover.

[0053] It should be noted that as an implementation scheme, it is also possible to synchronously detect the brush-opening distance of the armature, whether the axis of the armature is aligned with the axis of the motor rear cover by the armature axis calibration mechanism 50. If it is detected that the brush-opening distance of the armature is unqualified during the process of detecting whether the axis of the armature is aligned with the axis of the motor rear cover, the unqualified armature is taken away. If it is qualified, the qualified armature is installed into the motor rear cover.

[0054] Thus, through the above technical solutions in this embodiment, including the frame 10, the armature loading mechanism 20, the motor rear cover loading mechanism 30, at least one group of armature brush-opening mechanisms 40, at least one group of armature axis calibration mechanisms 50 for detecting the brush-opening distance of the armature and detecting and calibrating the coaxiality of the armature and the motor rear cover, the armature loading mechanism 20 and the motor rear cover loading mechanism 30 are installed in parallel on both sides of the frame 10, at least one group of armature assembly stations are arranged on the frame 10 along the movement direction of the motor rear cover loading mechanism 30, the armature brush-opening mechanism 40 is located between the armature assembly station and the armature loading mechanism 20, the armature axis calibration mechanism 50 is located above the armature assembly station. Before assembling the armature, it is first detected whether the axis of the armature is aligned with the axis of the motor rear cover. If they are aligned, the armature is installed into the motor rear cover, which improves the assembly quality and work efficiency of the armature.

[0055] Furthermore, please refer toFigures 6 to 8 , Figures 6 to 8 is Figures 1 to 5 a schematic structural view of the armature axis calibration mechanism 50 in the preferred embodiment shown.

[0056] The armature axis calibration mechanism 50 includes a mounting mechanism mounted on the frame 10, a first manipulator 501, an armature detection camera 502 for photographing the axes of the armature and the motor rear cover, and a first driving mechanism for driving the first manipulator 501 to move up and down and back and forth. The armature detection camera 502 is located directly above the assembly station. An axis calibration plate 503 is mounted on the mounting mechanism. A buffer surface 5031 is provided on one side of the axis calibration plate 503 close to the assembly station. One end of the first manipulator 501 is used to clamp the armature, and the other end is in contact with the buffer surface 5031 and can move up and down and back and forth relative to the buffer surface 5031 to drive the armature to move, so as to align the axis of the armature with the axis of the motor rear cover.

[0057] Among them, the armature detection camera 502 can adopt a CCD camera.

[0058] In specific implementation, the buffer surface 5031 of the axis calibration plate 503 can adopt an arc surface or an inclined surface. In this embodiment, by contacting the other end of the first manipulator 501 with the buffer surface 5031 of the axis calibration plate 503, it can play a role in buffering and limiting the movement of the first manipulator 501, avoiding the excessive movement amplitude of the first manipulator 501 resulting in the difficulty of aligning the axes of the armature and the motor rear cover, thereby improving the armature assembly quality and production efficiency.

[0059] More specifically, in this embodiment, a roller 504 is installed at the other end of the manipulator. The roller 504 is in contact with the buffer surface 5031 of the axis calibration plate 503. When the roller 504 moves along the buffer surface 5031 of the axis calibration plate 503, it drives the first manipulator 501 to move up and down and back and forth.

[0060] It can be understood that since the buffer surface 5031 is an arc surface or an inclined surface, when the roller 504 moves downward along the buffer surface 5031 of the axis calibration plate 503, the first manipulator 501 drives the armature to move slowly and synchronously downward and forward, and when the roller 504 moves upward along the buffer surface 5031 of the axis calibration plate 503, the first manipulator 501 drives the armature to move slowly and synchronously upward and backward.

[0061] Thus, in this embodiment, the other end of the manipulator is in contact with the buffer surface 5031 of the axis calibration plate 503 through the roller 504, which can reduce the frictional resistance during movement and make the movement of the first manipulator 501 more stable and reliable.

[0062] In this embodiment, the armature axis calibration mechanism 50 further includes a second driving mechanism 505 for driving the armature detection camera 502 to move up and down to adjust the focal length.

[0063] Please continue to refer to Figures 1 to 8 , and Figure 9 and Figure 10 In order to further improve the armature assembly efficiency, in this embodiment, two sets of the armature axis calibration mechanisms 50 are adopted. The armature detection cameras 502 of the two sets of armature axis calibration mechanisms 50 are connected by a connecting member 506. The connecting member 506 is horizontally movably installed on the installation mechanisms of the two sets of armature axis calibration mechanisms 50. The two sets of armature axis calibration mechanisms 50 share the second driving mechanism 505 to drive the connecting member 506 to move up and down to adjust the focal lengths of the armature detection cameras 502 of the two sets of armature axis calibration mechanisms 50.

[0064] It can be understood that in this embodiment, since two sets of armature axis calibration mechanisms 50 are adopted, correspondingly, two sets of armature brushing mechanisms 40, two sets of armature assembly stations, and two sets of armature conveying manipulators 60 are also adopted. Each set of axis calibration mechanisms is respectively matched with the corresponding armature brushing mechanism 40, armature assembly station, and armature conveying manipulator 60.

[0065] In this embodiment, the two sets of armature axis calibration mechanisms 50 share the second driving mechanism 505 to drive the connecting member 506 to move up and down, which not only reduces the number of the second driving mechanisms 505, lowers the production cost, but also can ensure the synchronization of the movement and detection of the armature detection cameras 502 of the two sets of armature axis calibration mechanisms 50.

[0066] The installation mechanism includes a first mounting seat 507 installed on the frame 10 and a second mounting seat 508 installed above the first mounting seat 507. A bracket 509 is installed on the second mounting seat 508. The axis calibration plate 503 is installed on the first mounting seat 507. The connecting member 506 is horizontally installed on the brackets 509 of the two sets of armature axis calibration mechanisms 50 and moves up and down along the bracket 509 under the drive of the second driving mechanism 505.

[0067] As an implementation manner, the second driving mechanism 505 can adopt a combination of a motor, a reducer, and a lead screw or other methods to drive the armature detection camera 502 to move up and down. The present invention does not limit this.

[0068] Specifically, the second driving mechanism 505 includes a motor, a speed reducer and a lead screw installed on the frame 10. The output end of the motor is connected to the input end of the speed reducer, the output end of the speed reducer is connected to the input end of the lead screw, and the output end of the lead screw is connected to the connecting member 506.

[0069] To further improve the armature assembly quality and production efficiency, in this embodiment, the armature assembly equipment further includes a motor rear cover detection mechanism 70 installed on the frame 10 at the entrance of the motor rear cover feeding mechanism 30, and a finished product detection mechanism 80 installed on the frame 10 at the exit of the motor rear cover feeding mechanism 30.

[0070] After the equipment is started, first convey the motor rear cover to the motor rear cover detection mechanism 70, and detect the quality of the motor rear cover through the motor rear cover detection mechanism 70. For example, detect whether the parts of the motor rear cover are complete. When the quality detection result of the motor rear cover is qualified, convey the motor rear cover to the brush assembly station. If the quality detection result is unqualified, take away the unqualified motor rear cover.

[0071] After installing the armature into the motor rear cover at the armature assembly station, convey the assembled finished product to the finished product detection mechanism 80, and the finished product detection mechanism 80 performs a re-inspection on the assembled finished product, takes away the unqualified products, and the qualified products are conveyed to the next process.

[0072] Specifically, as Figure 10 shown, in this embodiment, a second manipulator 90 is installed on the frame 10 at the corresponding position of the finished product detection mechanism 80, and the unqualified products are taken away through the second manipulator 90. During installation, an X-axis motion module 901 can be installed on the frame 10 first, and then the second manipulator 90 is installed on the X-axis motion module 901.

[0073] In this embodiment, by installing a motor rear cover detection mechanism 70 on the frame 10 at the entrance of the motor rear cover feeding mechanism 30 to perform a random detection on the motor rear cover, and installing a finished product detection mechanism 80 on the frame 10 at the exit of the motor rear cover feeding mechanism 30 to perform a re-inspection on the assembled finished product, the armature assembly quality is further improved.

[0074] It can be understood that in this embodiment, the armature feeding mechanism 20 includes a conveyor belt installed on the frame 10 and a fixture installed on the conveyor belt. The fixture is used to place the armature. In order to further improve the armature assembly efficiency, in this embodiment, a fixture return mechanism 100 is arranged in parallel on the outside of the conveyor belt on the frame 10 to return the empty fixtures of the conveyor belt.

[0075] In addition, in order to facilitate the user to grasp the armature detection and assembly situation in real time, a display screen 110 is installed on the frame 10 in this embodiment.

[0076] The beneficial effect of the armature assembly device of the present invention is that through the above technical solutions, the present invention includes a frame, an armature feeding mechanism, a motor rear cover feeding mechanism, at least one set of armature brushing mechanisms, and at least one set of armature axis calibration mechanisms for detecting the brushing distance of the armature and detecting and calibrating the coaxiality of the armature and the motor rear cover. The armature feeding mechanism and the motor rear cover feeding mechanism are installed in parallel on both sides of the frame. At least one set of armature assembly stations is arranged on the frame along the movement direction of the motor rear cover feeding mechanism. The armature brushing mechanism is located between the armature assembly station and the armature feeding mechanism. The armature axis calibration mechanism is located above the armature assembly station. Before assembling the armature, first detect whether the axis of the armature is aligned with the axis of the motor rear cover. If they are aligned, then install the armature into the motor rear cover, improving the assembly quality and working efficiency of the armature.

[0077] To achieve the above object, the present invention also proposes an armature assembly method, which is applied to the armature assembly device as described in the above embodiment. The armature assembly device includes a motor rear cover feeding mechanism, an armature brushing mechanism, and an armature axis calibration mechanism. As Figure 12 shown, the preferred embodiment of the armature assembly control method of the present invention includes:

[0078] Step S10, when the device is started, the motor rear cover feeding mechanism transports the motor rear cover to the assembly station, and the armature brushing mechanism brushes the armature and transports the brushed armature to the armature axis calibration mechanism.

[0079] It can be understood that in this embodiment, the armature assembly device may further include a control system, and the control system may adopt a processor or a microprocessor as the execution subject of the armature assembly method of the present invention.

[0080] In this embodiment, different armature brushing schemes can be adopted based on different types and models of armatures.

[0081] As an implementation, fork levers can be arranged on the relative two sides of the armature brushing mechanism on the frame according to the type and model of the armature. When brushing the armature, insert the two fork levers into the armature relatively, and then apply force in opposite directions to the two fork levers to achieve the operation of brushing the armature.

[0082] As another implementation, two ejector pins can be arranged in parallel below the frame according to the type and model of the armature. When brushing the armature, insert the two ejector pins upward into the armature, and then apply force in opposite directions to the two ejector pins to achieve the operation of brushing the armature.

[0083] When transporting the armature to the armature brushing mechanism or the armature axis calibration mechanism, it can be achieved by the armature transport manipulator. Specifically, an X-axis motion module can be installed on the frame between the armature assembly station and the armature feeding mechanism, and then the armature transport manipulator is installed on the X-axis motion module.

[0084] Step S20: The armature axis calibration mechanism detects the brushing distance of the armature and determines whether the armature brushing distance is qualified.

[0085] Specifically, in this embodiment, a CCD camera can be used to detect the brushing distance of the armature.

[0086] After the armature is brushed by the armature brushing mechanism and the armature is transported to the armature axis calibration mechanism by the armature transport manipulator, control the CCD camera to detect the brushing distance of the armature and determine whether the armature brushing distance is qualified.

[0087] Step S30: If the armature brushing distance is qualified, the armature axis calibration mechanism detects the coaxiality between the armature and the motor rear cover and determines whether the axes of the armature and the motor rear cover are aligned.

[0088] It should be noted that this step S30 can be carried out synchronously with step S20, or this step S30 can be executed first and then the above step S20. The present invention does not make any limitations in this regard.

[0089] Step S40: If the axes of the armature and the motor rear cover are aligned, the armature is inserted into the motor rear cover.

[0090] In this embodiment, if the result of the detection of the coaxiality between the armature and the motor rear cover by the armature axis calibration mechanism is that the axes of the armature and the motor rear cover are aligned, the armature is inserted into the motor rear cover. If the detection result is not aligned, continue to adjust the position of the armature until the axis of the armature is aligned with the axis of the motor rear cover.

[0091] In this embodiment, through the above technical solution, when the device is started, the motor rear cover feeding mechanism conveys the motor rear cover to the assembly station. The armature brushing mechanism brushes the armature, and conveys the brushed armature to the armature axis calibration mechanism. The armature axis calibration mechanism detects the brushing distance of the armature, and judges whether the armature brushing distance is qualified. If the armature brushing distance is qualified, the armature axis calibration mechanism detects the coaxiality between the armature and the motor rear cover, and judges whether the axes of the armature and the motor rear cover are aligned. If the axes of the armature and the motor rear cover are aligned, the armature is loaded into the motor rear cover, improving the assembly quality and working efficiency of the armature.

[0092] Further, in this embodiment, the armature axis calibration mechanism includes an axis calibration plate, a first manipulator and a first detection camera. The steps for the armature axis calibration mechanism to detect the coaxiality between the armature and the motor rear cover and judge whether the axes of the armature and the motor rear cover are aligned include:

[0093] The first manipulator moves up and down, back and forth along the buffer surface of the axis calibration plate to drive the axis of the armature towards the axis of the motor rear cover. The first detection camera takes pictures of the armature and the motor rear cover to judge whether the axes of the armature and the motor rear cover are aligned.

[0094] In addition, in order to further improve the assembly quality and working efficiency of the armature, in this embodiment, when controlling the motor rear cover feeding mechanism to convey the motor rear cover to the assembly station, the quality of the motor rear cover can be detected, and only the qualified motor rear covers are conveyed to the assembly station, while the unqualified motor rear covers are taken away.

[0095] After the armature is loaded into the motor rear cover, the quality of the assembled finished product can be detected, and the unqualified finished products are taken away, while the qualified finished products are continuously transported to the next station.

[0096] The beneficial effect of the armature assembly control method of the present invention is that through the above technical solution, when the device is started, the motor rear cover feeding mechanism conveys the motor rear cover to the assembly station. The armature brushing mechanism brushes the armature, and conveys the brushed armature to the armature axis calibration mechanism. The armature axis calibration mechanism detects the brushing distance of the armature, and judges whether the armature brushing distance is qualified. If the armature brushing distance is qualified, the armature axis calibration mechanism detects the coaxiality between the armature and the motor rear cover, and judges whether the axes of the armature and the motor rear cover are aligned. If the axes of the armature and the motor rear cover are aligned, the armature is loaded into the motor rear cover, improving the assembly quality and working efficiency of the armature.

[0097] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
