Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of stator bearing assembly, in particular to a stator bearing assembly device. BACKGROUND

[0002] With the development of science and technology, the application of electric machines is more and more widely, and electric machines almost cover all industries of modern society, such as various machines required by industrial manufacturing, electric vehicles, scooters, balance cars and the like for transportation.

[0003] The assembly of stators and oil-containing bearings is an important link in the manufacturing of electric machines, and the assembly of stators and oil-containing bearings is usually performed by manually taking stators and oil-containing bearings and placing them on equipment, and then performing press fitting. This type of feeding and press fitting has low efficiency, which limits the production efficiency of electric machines. CONTENT OF THE UTILITY MODEL

[0004] In view of the problems existing in the prior art, the present disclosure provides a stator bearing assembly device to improve the situation that the assembly of stators and bearings requires manual feeding, resulting in low efficiency of feeding and press fitting of stators and bearings.

[0005] To achieve the above-mentioned purposes and other related purposes, the present disclosure provides a stator bearing assembly device, which comprises a bearing mechanism, a press fitting mechanism, a bearing carrying mechanism, a stator transfer mechanism, a first stator feeding mechanism and a second stator feeding mechanism. The bearing mechanism comprises a plurality of bearing members configured to place stators and bearings. The press fitting mechanism is configured to press fit the stators and bearings on the bearing members. The bearing carrying mechanism is configured to carry the bearings to the bearing members. The stator transfer mechanism has at least two stator placing members that reciprocate between a first position and a second position, and the stator placing members are configured to place stators. The first stator feeding mechanism takes the stators from the stator placing members at the first position and transports them to the bearing members on which the bearings are placed. The second stator feeding mechanism takes the stators from the stator tray and transports them to the stator placing members at the second position.

[0006] The stator bearing assembly device comprises a bearing conveying mechanism and a first stator feeding mechanism. The bearing and the stator are conveyed to the bearing carrier by the bearing conveying mechanism and the first stator feeding mechanism respectively, and then the stator and the bearing are pressed by the pressing mechanism. The mechanical automatic feeding reduces the workload of workers, improves the feeding efficiency, and improves the motor production efficiency. The stator is usually placed on the stator brittle disc, and the stator feeding mechanism needs to take materials at different positions on the stator brittle disc, which causes the long stroke of the stator feeding mechanism. The bearing can be arranged in a fixed position in turn by vibration due to its own structural characteristics, and the bearing conveying mechanism only needs to move between two fixed points, so that the feeding stroke of the bearing is shorter than that of the stator. The stator feeding is realized by two-step feeding through the second stator feeding mechanism, the stator transfer mechanism and the first stator feeding mechanism, thereby shortening the stator feeding cycle time, coordinating the bearing feeding and the stator feeding, effectively improving the feeding efficiency, improving the stator bearing assembly efficiency, and improving the motor production efficiency.

[0007] In an example embodiment of the present disclosure, the bearing mechanism comprises a bearing disc and a bearing driving mechanism. The bearing disc is provided with a plurality of bearing carriers. The bearing driving mechanism drives the bearing disc to rotate, so that the bearing carriers move to the pressing position of the pressing mechanism after receiving the bearing and the stator.

[0008] The bearing disc is driven to rotate by the bearing driving mechanism, so that the bearing carriers on the bearing disc can pass through the bearing conveying mechanism and the first stator feeding mechanism in turn, and then the bearing and the stator are fed in turn to realize automatic feeding. By providing a plurality of bearing carriers, continuous feeding and pressing are realized, thereby ensuring the efficiency of stator bearing assembly.

[0009] In an example embodiment of the present disclosure, the bearing carrier comprises a bearing part, and the bearing part is movably arranged on the bearing disc. The pressing mechanism comprises an upper pressing part and a lower pressing part. The upper pressing part is located above the bearing disc, and the upper pressing part is configured to press the stator and the bearing. The lower pressing part is arranged corresponding to the upper pressing part, and the lower pressing part is located below the bearing disc. The lower pressing part is configured to support the bearing part.

[0010] The upper pressing part and the lower pressing part cooperate to press the stator and the bearing, wherein the upper pressing part moves downward to press the stator and the bearing. The bearing part is movably arranged on the bearing disc, and when the bearing part moves to the lower pressing part, the lower pressing part is located below the bearing part and supports the bearing part, so that the pressure of the stator and the bearing during pressing is borne by the lower pressing part, effectively reducing the pressure on the bearing disc, avoiding the inclination of the bearing disc, and improving the service life of the bearing disc.

[0011] In an example embodiment of the present disclosure, the bearing carrier comprises a reset part. The reset part applies a force to the bearing part in response to the bearing part being separated from the bearing disc, so that when the bearing carrier is separated from the lower pressing part, the bearing part is pressed against the bearing disc.

[0012] The carrier is kept in the reset state by the reset member after being separated from the pressing member, thereby ensuring that the stator and the bearing remain in a fixed position after pressing, facilitating material feeding, and facilitating repeated feeding of the carrier.

[0013] In an example embodiment of the present disclosure, the carrier portion penetrates the carrier disc and moves up and down relative to the carrier disc. The carrier portion includes a first limiting portion that abuts against the carrier disc to limit the carrier portion from separating downward from the carrier disc. The top surface of the pressing member is arc-shaped, and when the carrier portion abuts against the top of the pressing member, the first limiting portion separates upward from the carrier disc.

[0014] The carrier portion is movably arranged on the carrier disc, and the first limiting portion abuts against the carrier disc to limit the carrier portion, so that the relative position of the carrier portion and the carrier disc is fixed, facilitating feeding and discharging of the carrier portion. The top surface of the pressing member is arc-shaped, and when the carrier portion abuts against the top surface of the pressing member and continues to move, the force exerted by the pressing member on the carrier portion causes the carrier portion to move upward relative to the carrier disc, and the first limiting portion separates from the carrier disc. The upper pressing member presses the stator and the bearing, and the lower pressing member supports the carrier portion, reducing the stress on the carrier disc and the radial force on the carrier driving mechanism, thereby prolonging the service life of the carrier driving mechanism and the carrier disc.

[0015] In an example embodiment of the present disclosure, the carrier portion includes a positioning rod, and the end of the positioning rod has a tapered guide head. The positioning rod cooperates with the bearing.

[0016] The tapered guide head serves as a guide function, facilitating the placement of the bearing on the positioning rod, thereby facilitating the guarantee of the coaxiality of the bearing and the stator and improving the precision and quality of the pressing of the bearing and the stator.

[0017] In an example embodiment of the present disclosure, the stator and bearing assembly device includes a vibration feeding mechanism and a bearing feeding mechanism. The vibration feeding mechanism is configured to vibrate and convey the loaded bearings to the outlet of the vibration feeding mechanism. The bearing feeding mechanism is configured to sequentially transport the bearings at the outlet of the vibration feeding mechanism so as to facilitate the bearing carrying mechanism to carry the bearings. The bearing feeding mechanism includes a feeding block, a baffle, and a feeding driving mechanism. The feeding block is provided with a receiving opening for receiving the bearings, and the receiving opening faces the outlet of the vibration feeding mechanism. The baffle is arranged on one side of the feeding block having the receiving opening, and the baffle is provided with a gap for allowing the bearings to pass through, and the gap is arranged at the outlet of the vibration feeding mechanism. The feeding driving mechanism drives the feeding block to move along the baffle, so that the feeding block sequentially transports the bearings conveyed by the vibration feeding mechanism to the bearing carrying mechanism.

[0018] The vibration feeding mechanism can sequentially sort and deliver the disordered bearings to the outlet of the vibration feeding mechanism, thereby improving the convenience of bearing feeding. The bearings have a certain degree of freedom in the outlet direction at the outlet of the vibration feeding mechanism, so that the position of the bearings in the outlet direction will deviate. The bearing feeding mechanism sequentially transports the bearings at the outlet of the vibration feeding mechanism, so that the bearings are moved to a fixed position. The bearing conveying mechanism takes the bearings from the fixed position, which facilitates taking the bearings, reduces the stroke of the bearing conveying mechanism, and improves the convenience of bearing feeding.

[0019] The receiving block of the bearing receiving structure has a receiving opening. The bearing is moved from the outlet of the vibration feeding mechanism into the receiving opening, and then the receiving block moves. The receiving opening is closed by the baffle, and the bearing is limited in the receiving opening. When the receiving block moves relative to the baffle, if the bearing is not completely in the receiving opening, the baffle will squeeze the bearing to make the bearing completely enter the receiving opening, so as to limit the position of the bearing, thereby facilitating the bearing conveying mechanism to take the bearings from the fixed conveying position, saving the layout space of the bearing conveying mechanism, reducing the number of parts, and reducing the cost.

[0020] In an example embodiment of the present disclosure, the stator transfer mechanism includes a stator transfer plate and a transfer plate driving mechanism. The stator placing piece is arranged on the stator transfer plate. The transfer plate driving mechanism drives the stator transfer plate to make a cyclic reciprocating rotation of the transfer plate driving mechanism.

[0021] The stator placing piece is arranged on the stator transfer plate to place the stator. The transfer plate driving mechanism drives the stator transfer plate to make a cyclic reciprocating rotation, so as to realize the reciprocating movement of the stator placing piece between the first position and the second position. The first stator feeding mechanism takes the stator from the stator placing piece at the first position, and the second stator feeding mechanism places the stator on the stator placing piece at the second position.

[0022] In an example embodiment of the present disclosure, the outer diameter of the stator placing piece is matched with the inner diameter of the stator, and the top of the stator placing piece has a conical guide portion.

[0023] The conical guide portion at the top of the stator placing piece plays a guiding role, so that the stator can be accurately sleeved on the stator placing piece, thereby facilitating the first stator feeding mechanism to take the stator from the stator placing piece and transport it to the bearing-carrying piece on which the bearings are placed, and facilitating the coaxial arrangement of the bearings and the stator.

[0024] In an example embodiment of the present disclosure, the stator bearing assembly device includes a fragile disc lifting mechanism. The fragile disc lifting mechanism transports the stator fragile disc to the taking position of the second stator feeding mechanism.

[0025] The fragile disc lifting mechanism can transport the stator fragile disc to the taking position of the second stator feeding mechanism, thereby facilitating the automatic feeding of the stator and improving the convenience of stator feeding.

[0026] In an example embodiment of the present disclosure, the second stator feeding mechanism comprises a second stator gripper and a second driving mechanism. The second stator gripper is configured to pick and place the stator. The second driving mechanism drives the second stator gripper to move from the stator brittle disc to the stator placing part.

[0027] The second driving mechanism drives the second stator gripper to move so that the second stator gripper places the stator on the stator placing part after picking the stator from the stator brittle disc for the first stator feeding mechanism to pick and place the stator.

[0028] In an example embodiment of the present disclosure, the press-fitting mechanism comprises a detection mechanism configured to detect whether the press-fitting mechanism carries the press-fitted stator and bearing.

[0029] The press-fitting mechanism applies pressure to the stator so that the stator is press-fitted with the bearing. After press-fitting, the press-fitting mechanism has a risk of carrying the stator and the bearing upward. The detection mechanism can detect the press-fitting mechanism, so that the situation of the press-fitting mechanism carrying the stator and the bearing can be found in time, and measures can be taken to avoid affecting subsequent press-fitting.

[0030] In combination with the prior art, the present disclosure has the following beneficial effects:

[0031] The existing stator bearing assembly device usually needs manual feeding, which has low feeding efficiency, resulting in low stator bearing assembly efficiency and low motor production efficiency. The stator bearing assembly device of the present disclosure comprises a bearing conveying mechanism and a first stator feeding mechanism. The bearing and the stator are conveyed to the bearing part by the bearing conveying mechanism and the first stator feeding mechanism, respectively, and then the stator and the bearing are press-fitted by the press-fitting mechanism. The mechanical automatic feeding reduces the workload of workers, improves the feeding efficiency, and improves the motor production efficiency.

[0032] The stator is usually placed on the stator brittle disc, and the stator feeding mechanism needs to pick up at different positions on the stator brittle disc, which results in a long stroke of the stator feeding mechanism. The bearing can be arranged in a fixed position in sequence by vibration due to its own structural characteristics, and the bearing conveying mechanism only needs to move between two fixed points, so that the feeding stroke of the bearing is shorter than that of the stator. The stator feeding is realized by two-step feeding of the second stator feeding mechanism, the stator transfer mechanism and the first stator feeding mechanism, which shortens the stator feeding cycle time, coordinates the bearing feeding and the stator feeding, effectively improves the feeding efficiency, improves the stator bearing assembly efficiency, and improves the motor production efficiency.

[0062] The present disclosure is illustrated by way of example and not limitation in the figures of the accompanying drawings, in which like references indicate similar, but not necessarily identical, elements. Other advantages and novel features of the present disclosure will become apparent from the following detailed description, when considered in conjunction with the non-limiting, exemplary drawings. The present disclosure can be put into practice by a variety of different embodiments and can be implemented in various ways, and the present disclosure should not be limited to the specific embodiments described in the description. It should be noted that the following embodiments and features thereof can be combined with each other, without conflict, under the condition that they are not mutually exclusive. It should also be understood that the terms used in the embodiments of the present disclosure are intended to describe specific embodiments, and are not intended to limit the scope of protection of the present disclosure. The test methods in the following embodiments are not specified, and are generally carried out under conventional conditions or under conditions recommended by the manufacturer.

[0063] When the embodiments give a numerical range, it should be understood that, unless otherwise stated in the present disclosure, both endpoints of each numerical range and any numerical value between the two endpoints can be selected. Unless otherwise defined, all technical and scientific terms used in the present disclosure are consistent with the understanding of the prior art by those skilled in the art and the description of the present disclosure, and any method, equipment and material of the prior art similar or equivalent to the method, equipment and material of the embodiments of the present disclosure can be used to implement the present disclosure.

[0064] It should be noted that the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the specification are only for the convenience of clear description, and are not intended to limit the scope of the present disclosure. The change or adjustment of the relative relationship, without substantially changing the technical content, is also regarded as the scope of the present disclosure.

[0065] In the related art, the stator and bearing assembly is to place the wound stator in the plastic brittle disc, place the bearing in the plastic box, and then manually take the material and place it on the pressing equipment, and then press. Manual feeding has the problem of low feeding and pressing efficiency, which limits the production efficiency of the motor.

[0066] In view of this, please refer to Figures 1 to 18The present disclosure provides a stator bearing assembly device, comprising a bearing mechanism 100, a pressing mechanism 200, a bearing conveying mechanism 300, a stator transfer mechanism 500, a first stator feeding mechanism 400 and a second stator feeding mechanism 600. The bearing mechanism 100 comprises a plurality of bearing pieces 110 configured to place the stator and the bearing. The pressing mechanism 200 is configured to press the stator and the bearing on the bearing piece 110. The bearing conveying mechanism 300 is configured to convey the bearing to the bearing piece 110. The stator transfer mechanism 500 has at least two stator placing pieces 510 reciprocating between a first position and a second position, and the stator placing pieces 510 are configured to place the stator. The first stator feeding mechanism 400 takes the stator from the stator placing piece 510 in the first position and delivers it to the bearing piece 110 where the bearing is placed. The second stator feeding mechanism 600 takes the stator from the stator fragile tray and delivers it to the stator placing piece 510 in the second position.

[0067] The stator bearing assembly device conveys the bearing and the stator to the bearing piece 110 by the bearing conveying mechanism 300 and the first stator feeding mechanism 400 respectively, and then presses the stator and the bearing by the pressing mechanism 200, which realizes automatic feeding, reduces the workload of workers, improves the feeding efficiency and the motor production efficiency.

[0068] The stator is usually placed on a stator fragile tray, which has a large size. The stator feeding mechanism needs to take the stator from different positions on the stator fragile tray, which results in a long stroke of the stator feeding mechanism. The bearing can be arranged in fixed positions in sequence by vibration due to its structural characteristics, and the bearing conveying mechanism 300 only needs to move between two fixed points. Therefore, the stroke of the stator feeding is longer than that of the bearing feeding. The two-step feeding of the stator feeding is realized by the second stator feeding mechanism 600, the stator transfer mechanism 500 and the first stator feeding mechanism 400, which shortens the stator feeding cycle time and the stator feeding beat. The feeding efficiency, the stator bearing pressing efficiency and the motor production efficiency are effectively improved by coordinating the bearing feeding and the stator feeding.

[0069] Please refer to Figure 1 and Figure 3 In an embodiment, the bearing mechanism 100 comprises a bearing disc 120 and a bearing driving mechanism 130. The bearing disc 120 is used to place the bearing piece 110, and a plurality of bearing pieces 110 are arranged on the bearing disc 120 to form continuous feeding and pressing, which improves the pressing efficiency of the stator and the bearing. The plurality of bearing pieces 110 are arranged in a circumferential array on the bearing disc 120 to realize stable and continuous feeding and pressing.

[0070] In an embodiment, the number of the carriers 110 is greater than or equal to three, for example, 3, 4, 5, 6 or more, so that the bearing loading station, the stator loading station and the press fitting station can work simultaneously. Of course, in other embodiments, the number of the carriers 110 can also be 2 to meet different loading and press fitting needs.

[0071] Referring to Figure 3 , the carrier disc 120 can be disc-shaped, and the disc-shaped carrier disc 120 is more balanced when rotating, which reduces the radial force on the carrier driving mechanism 130 and improves the service life of the carrier driving mechanism 130.

[0072] As other optional ways, the carrier disc 120 can also be other shapes, for example, the carrier disc 120 is square, or the carrier disc 120 is a H-shaped, octagonal, etc.

[0073] The carrier driving mechanism 130 drives the carrier disc 120 to rotate, so that the carrier 110 receives the bearing and the stator and then moves to the press fitting position of the press fitting mechanism 200. The carrier driving mechanism 130 drives the carrier disc 120 to rotate, so that the carrier 110 on the carrier disc 120 can pass through the bearing conveying mechanism 300 and the first stator loading mechanism 400 in turn, thereby realizing the sequential loading of the bearing and the stator and achieving automatic loading.

[0074] The carrier driving mechanism 130 includes a motor, and the carrier disc 120 is directly connected to the output shaft of the motor, or the carrier disc 120 is indirectly connected to the output shaft of the motor through a gear structure, so as to drive the carrier disc 120 to rotate by the motor.

[0075] Referring to Figure 4 and Figure 5 , in an embodiment, the carrier 110 includes a carrier part 111, and the carrier part 111 is movably arranged on the carrier disc 120.

[0076] Referring to Figure 15 and Figure 16 , the press fitting mechanism 200 includes an upper press fitting part 230 and a lower press fitting part 210. The upper press fitting part 230 is located above the carrier disc 120, and is used for press fitting the stator and the bearing. The lower press fitting part 210 is arranged corresponding to the upper press fitting part 230, and is located below the carrier disc 120. The lower press fitting part 210 is used for supporting the carrier part 111. In other words, when the carrier 110 moves to the press fitting station, the lower press fitting part 210 supports the carrier part 111, so as to reduce or avoid the carrier disc 120 from being subjected to the force generated by the upper press fitting part 230 extruding the stator. The lower press fitting part 210 bears the pressure when the stator and the bearing are press fitted, effectively reducing the pressure on the carrier disc 120, avoiding the carrier disc 120 from tilting, preventing the carrier disc 120 from deforming, and improving the service life of the carrier disc 120.

[0077] In an embodiment, the bearing disc 120 is provided with a through hole, and the bearing part 111 penetrates through the through hole, so that the bearing part 111 moves up and down relative to the bearing disc 120.

[0078] Please refer to Figure 5 The bearing part 111 includes a first limiting part 1111, which is arranged above the bearing disc 120, and a projection of the first limiting part 1111 along an axial direction of the through hole of the bearing disc 120 at least partially exceeds the through hole of the bearing disc 120. Under the action of gravity, the first limiting part 1111 abuts against the bearing disc 120 and limits the bearing part 111 from being separated downward from the bearing disc 120. The relative position between the bearing part 111 and the bearing disc 120 is fixed, which facilitates the bearing part 111 to perform material receiving and discharging.

[0079] Please refer to Figure 15 and Figure 16 The top surface of the pressing assembly 210 is a curved surface. When the bearing part 111 abuts against the top surface of the pressing assembly 210 and continues to move along the top surface of the pressing assembly 210, the force applied by the pressing assembly 210 to the bearing part 111 causes the bearing part 111 to move upward relative to the bearing disc 120, and then the first limiting part 1111 is separated from the position of abutting against the bearing disc 120. Then, the pressing assembly 230 is used to press fit the stator and the bearing, and the pressing assembly 210 is used to support the bearing part 111, so as to reduce the stress of the bearing disc 120 and the radial force received by the bearing driving mechanism 130, and improve the service life of the bearing driving mechanism 130 and the bearing disc 120.

[0080] Of course, as some optional manners, the top surface of the pressing assembly 210 can also be an inclined surface. When the bearing part 111 moves along the top surface of the pressing assembly 210, the force applied by the pressing assembly 210 causes the bearing part 111 to move upward, and then the first limiting part 1111 is separated from the position of abutting against the bearing disc 120. Alternatively, the side surface of the bearing part 111 has an inclined surface. When the inclined surface of the bearing part 111 abuts against the pressing assembly 210 and continues to move, the bearing part 111 moves upward relative to the bearing disc 120, so that the first limiting part 1111 is separated from the position of abutting against the bearing disc 120, so as to reduce or avoid the stress of the bearing disc 120 and improve the service life of the bearing disc 120 and the bearing driving mechanism 130.

[0081] Please refer to Figure 4 and Figure 5In an embodiment, the carrier 110 comprises a reset member 112, which applies a force to the carrier portion 111 to make the carrier portion 111 press against the carrier disc 120 when the carrier 110 is separated from the pressing assembly 210, in response to the carrier portion 111 being separated from the carrier disc 120. The carrier 110 is kept in the reset state by the reset member 112 after being separated from the pressing assembly 210, thereby ensuring that the stator and the bearing remain in a fixed position after being pressed, facilitating unloading, and facilitating repeated loading of the carrier 110.

[0082] In an embodiment, the reset member 112 is an elastic reset member 112, such as a spring, which is sleeved on the carrier portion 111 below the carrier disc 120, one end of the spring abuts against the carrier disc 120, and the other end abuts against the carrier portion 111. When the carrier portion 111 moves upward relative to the carrier disc 120, the spring is compressed to generate an elastic force, which is applied to the carrier portion 111 in a downward direction, thereby resetting the carrier portion 111 under the action of gravity and the elastic force after being separated from the pressing assembly 210.

[0083] In an embodiment, when the first limiting portion 1111 abuts against the carrier disc 120 in the reset state of the carrier portion 111, the spring is still in a compressed state, and the elastic force is applied to the carrier portion 111 and the carrier disc 120 to increase the force between the first limiting portion 1111 and the carrier disc 120, reduce the shaking of the carrier portion 111, ensure the relative fixation of the carrier portion 111 and the carrier disc 120, facilitate the loading of the carrier portion 111 or the unloading from the carrier portion 111, and improve the accuracy of loading and unloading.

[0084] Please refer to Figure 4 In an embodiment, the lower portion of the carrier portion 111 comprises a second limiting portion 1113, which limits the spring between the second limiting portion 1113 and the carrier disc 120, and the elastic force of the spring is applied to the second limiting portion 1113 to facilitate the resetting of the carrier portion 111.

[0085] Please refer to Figure 3 and Figure 5 In an embodiment, the carrier disc 120 comprises a shaft sleeve 121, which is arranged in the through hole of the carrier disc 120, and the shaft sleeve 121 is sleeved on the carrier portion 111, and the first limiting portion 1111 abuts against the shaft sleeve 121. By arranging the shaft sleeve 121, the wear of the through hole of the carrier disc 120 can be reduced, and the stress deformation and wear of the carrier disc 120 caused by the abutment of the first limiting portion 1111 against the carrier disc 120 can also be reduced, thereby improving the service life of the carrier disc 120.

[0086] The shaft sleeve 121 can be fixedly arranged on the bearing disc 120, and the fixing manner includes but is not limited to bolt connection and plug connection. The shaft sleeve 121 can also be detachably arranged on the bearing disc 120, so as to facilitate replacement of the shaft sleeve 121 and avoid the case that the entire bearing disc 120 needs to be replaced due to damage of a single shaft sleeve 121.

[0087] Please refer to Figure 4 In an embodiment, the bearing part 111 includes a positioning rod 1112, and an end of the positioning rod 1112 is provided with a tapered guide head. The positioning rod 1112 is matched with the bearing. In the related art, the bearing is prone to deviation during manual loading, so that the coaxiality of the stator and the bearing cannot be guaranteed. The tapered guide head of the bearing part 111 has a guiding function, facilitates placement of the bearing on the positioning rod 1112, and thus is beneficial to guarantee the coaxiality of the bearing and the stator and improve the precision and quality of bearing and stator press fitting.

[0088] In an embodiment, the bearing part 111 includes a magnetic attraction piece, which is used to attract the bottom wall of the bearing, so as to fix the bearing on the bearing part 111, improve the stability of the bearing, reduce the risk of shaking or falling of the bearing during rotation of the bearing disc 120, and be beneficial to improve the coaxiality of the bearing and the stator.

[0089] Please refer to Figure 1 and Figure 2 In an embodiment, the stator bearing assembly device includes a vibration feeding mechanism 700 and a bearing receiving mechanism 800. The vibration feeding mechanism 700 is used to vibrate and convey the loaded bearings to the outlet of the vibration feeding mechanism 700. The vibration feeding mechanism 700 can sequentially sort and convey the disordered bearings to the outlet of the vibration feeding mechanism 700 and guarantee the placement form of the bearings, so as to improve the convenience of bearing feeding.

[0090] The bearing receiving mechanism 800 is used to sequentially convey the bearings at the outlet of the vibration feeding mechanism 700. The bearings have a certain degree of freedom in the outlet direction at the outlet of the vibration feeding mechanism 700, so that the positions of the bearings in the outlet direction are deviated. The bearing receiving mechanism 800 is used to move the bearings to the conveying position of the bearing conveying mechanism 300, so that the bearings are moved to the fixed position. The bearing conveying mechanism 300 takes the bearings from the fixed position, facilitates taking of the bearings, reduces the stroke of the bearing conveying mechanism 300, improves the speed of bearing feeding, reduces the requirements of the bearing conveying mechanism 300, and thus reduces the cost of the bearing conveying mechanism 300.

[0091] Please refer to Figure 8In an embodiment, the bearing receiving mechanism 800 comprises a receiving block 810, a baffle 820 and a receiving drive mechanism 830. The receiving block 810 is provided with a receiving opening 811 for accommodating the bearing, which is adapted to the size of the bearing and faces the outlet of the vibrating feeding mechanism 700, thereby facilitating the bearing to be pushed into the receiving opening 811 by the vibrating feeding mechanism 700. The baffle 820 is arranged on the side of the receiving block 810 with the receiving opening 811, and is provided with an opening for the bearing to pass through, which is arranged at the outlet of the vibrating feeding mechanism 700. The receiving drive mechanism 830 drives the receiving block 810 to move along the baffle 820, so that the receiving block 810 sequentially transports the bearing delivered by the vibrating feeding mechanism 700 to the bearing carrying mechanism 300.

[0092] The baffle 820 is provided with an opening, and the receiving block 810 is provided with a receiving opening 811. The bearing is pushed or pressed by the bearing behind the bearing at the outlet of the vibrating feeding mechanism 700, moves into the receiving opening 811 through the opening, and then the receiving block 810 moves. The receiving opening 811 is closed by the baffle 820, the bearing is limited in the receiving opening 811, and the bearing moves with the receiving block 810. When the receiving block 810 moves relative to the baffle 820, if the bearing is not completely in the receiving opening 811, the baffle 820 will press the bearing to make the bearing completely enter the receiving opening 811, so as to limit the position of the bearing, thereby facilitating the bearing carrying mechanism 300 to take the bearing from the fixed carrying position, saving the layout space of the bearing carrying mechanism 300, reducing the number of parts and the cost.

[0093] In an embodiment, the receiving block 810 is driven by a drive mechanism, which can be a combination of a motor and a lead screw, or a pneumatic telescopic rod, a hydraulic telescopic rod or an electric telescopic rod, so as to realize the linear reciprocating motion of the receiving block 810.

[0095] The bearing carrying mechanism 300 drives the bearing clamping jaw 310 to move in at least two directions. The drive in the two directions can be a combination of a motor and a lead screw, or a pneumatic cylinder or the like. Alternatively, the drive in one direction can be a combination of a motor and a lead screw, and the drive in the other direction can be a pneumatic cylinder or the like, so as to realize the feeding of the bearing by the bearing clamping jaw 310.

The transfer plate driving mechanism 530 drives the stator transfer plate 520 to rotate cyclically and reciprocally, so as to realize the reciprocation of the stator placing pieces 510 between the first position and the second position. The first stator feeding mechanism 400 takes out the stator from the stator placing piece 510 at the first position, and the second stator feeding mechanism 600 places the stator on the stator placing piece 510 at the second position.

[0097] In an embodiment, the outer diameter of the stator placing piece 510 is matched with the inner diameter of the stator, and the top of the stator placing piece 510 is provided with a conical guide part. The conical guide part plays a guiding role, so that the stator can be accurately sleeved on the stator placing piece 510, and the placing posture of the stator is ensured to meet the expected design, thereby facilitating the first stator feeding mechanism 400 to take out the stator from the stator placing piece 510 and transport it to the bearing-carrying piece 110 on which the bearing is placed, and being beneficial to the coaxiality of the bearing and the stator.

[0098] The stator placing piece 510 is fixedly installed on the stator transfer plate 520, and the installation mode includes but is not limited to bolt connection, plug-in connection, and threaded connection.

[0099] The transfer plate driving mechanism 530 can be a swing cylinder, so as to realize the reciprocating swing of the stator transfer plate 520, and make the stator placing pieces 510 reciprocate between the first position and the second position. The transfer plate driving mechanism 530 can also be a motor, which can realize the cyclic swing or reciprocating swing of the stator transfer plate 520, so as to make the stator placing pieces 510 move between the first position and the second position. The transfer plate driving mechanism 530 can also be other driving mechanisms to realize the rotation of the stator transfer plate 520, so as to make the stator placing pieces 510 move between the first position and the second position.

[0100] Please refer to Figure 9 In an embodiment, the first stator feeding mechanism 400 comprises a first stator clamping jaw 410 and a first driving mechanism 420. The first stator clamping jaw 410 is used for taking and placing the stator, and the first driving mechanism 420 drives the first stator clamping jaw 410 to move, so as to take out the stator from the stator placing piece 510 at the first position and place it on the bearing-carrying piece 110 on which the bearing has been placed on the bearing-carrying disc 120. The feeding of the stator is realized, and the preparation for the press-fitting of the stator and the bearing is made.

[0101] The first stator clamping jaw 410 clamps and places the stator to a fixed position, and the first driving mechanism 420 drives the first stator clamping jaw 410 to move in at least two directions, which is achieved by two drives. The two drives can be a combination of a motor and a screw, or can be a telescopic cylinder such as a pneumatic telescopic cylinder, a hydraulic telescopic cylinder, an electric telescopic cylinder, etc. Alternatively, one of the two drives can be a combination of a motor and a screw, and the other can be a telescopic cylinder, etc. The first driving mechanism 420 can also be other driving combinations to achieve the movement of the first stator clamping jaw 410 in two directions.

[0102] Referring to Figure 11 In an embodiment, the stator bearing assembly device comprises a fragile disc lifting mechanism 640, which transports the stator fragile disc to the taking position of the second stator feeding mechanism 600. In order to facilitate the feeding of the stator and reduce the workload of the operator, the fragile disc lifting mechanism 640 can realize the sequential feeding of multiple stator fragile discs. The fragile disc lifting mechanism 640 sequentially transports the stator fragile discs to the taking position of the second stator feeding mechanism 600, facilitating the automatic feeding of the stator and improving the convenience of stator feeding.

[0103] Referring to Figure 12 In an embodiment, the second stator feeding mechanism 600 comprises a second stator clamping jaw 620 and a second driving mechanism 630. The second stator clamping jaw 620 is used to take and place the stator, and the second driving mechanism 630 drives the second stator clamping jaw 620 to move from the stator fragile disc to the stator placing piece 510, so that the second stator clamping jaw 620 takes the stator from the stator fragile disc and places it on the stator placing piece 510 at the second position, for the first stator feeding mechanism 400 to take and deliver the stator.

[0104] In order to take out the stator in the stator fragile disc, the second driving mechanism 630 needs to drive the second stator clamping jaw 620 to move in three directions, which is achieved by three drives. The three drives can be one or more of a telescopic cylinder, a motor and a screw, a motor and a gear rack, etc. Alternatively, the drive can be other driving modes to achieve the driving of the second driving mechanism 630 on the second stator clamping jaw 620, so that the second stator clamping jaw 620 takes out the stator in the stator fragile disc and transports it to the stator placing piece 510.

[0105] When feeding the stator, the second stator clamping jaw 620 is placed on the stator placing piece 510 at the second position after taking it from the stator fragile disc, and then the stator transfer plate driving mechanism 530 drives the stator transfer plate 520 to rotate, and the stator placing piece 510 at the second position rotates to the first position for the first stator clamping jaw 410 to clamp and place it on the bearing-carrying piece 110.

[0106] When the stator transfer plate 520 rotates, the positions of the first position and the second position of the stator placing piece 510 are exchanged, so as to facilitate the second stator feeding mechanism 600 to feed the stator placing piece 510, and the first stator feeding mechanism 400 takes the material from the stator placing piece 510. By arranging the stator transfer plate 520, the stator feeding time is reduced, the stator feeding and bearing feeding are effectively planned, the feeding efficiency is improved, the bearing and stator pressing efficiency is improved, and the motor production rate is improved.

[0108] The stator brittle disc of the taken-out stator is removed by the brittle disc taking part 610, so that the brittle disc lifting mechanism 640 realizes the sequential feeding of multiple stator brittle discs, effectively improves the feeding efficiency, and facilitates the feeding of the stator.

[0109] In order to improve the space utilization and facilitate the arrangement of the stator bearing assembly device, the brittle disc taking part 610 moves the stator brittle disc from the second stator feeding mechanism 600 taking part to the side of the second stator feeding mechanism 600 taking part, reducing the space occupation of the stator brittle disc storage place.

[0110] In an embodiment, the brittle disc taking part 610 is connected with the second driving mechanism 630, so as to drive the brittle disc taking part 610 to move by the second driving mechanism 630. The brittle disc taking part 610 is driven by the second driving mechanism 630 which drives the second stator clamping jaw 620 to move, effectively reducing the number of driving mechanisms and reducing the cost. At the same time, the space occupation of the driving mechanism can be reduced, the space utilization of the stator bearing assembly device is improved, and the installation and use of the stator bearing assembly device are facilitated.

[0113] Please refer to Figure 15 In an embodiment, the pressing mechanism 200 comprises a detection mechanism 220, which is configured to detect whether the pressing mechanism 200 carries the pressed stator and bearing.

[0114] The pressing mechanism 200 applies pressure to the stator so that the stator is pressed with the bearing. After pressing, the pressing mechanism 200 has a risk of carrying the stator and the bearing upwards. The detection mechanism 220 can detect the pressing mechanism 200, so that the situation of the pressing mechanism 200 carrying the stator and the bearing upwards can be found in time, and then measures can be taken to avoid affecting the subsequent pressing.

The plurality of feeding clamp jaws 910 are arranged at equal intervals, and the distance between adjacent feeding clamp jaws 910 is equal to the distance between adjacent relay parts.

[0120] The stator bearing assembly device has a certain distance from the station of the next process. The relay part is used to transfer the pressed stator and bearing, so as to reduce the stroke of the feeding driving mechanism 920, effectively improve the feeding speed, and improve the motor production speed.

[0121] The stator bearing assembly device of the present disclosure carries the bearing and the stator to the bearing carrier 110 through the bearing carrying mechanism 300 and the first stator feeding mechanism 400, and then carries out the pressing of the stator and the bearing through the pressing mechanism 200, which realizes the mechanical automatic feeding, reduces the workload of workers, improves the feeding efficiency, and improves the motor production efficiency. The stator feeding is realized by two-step feeding through the second stator feeding mechanism 600, the stator transfer mechanism 500 and the first stator feeding mechanism 400, thereby shortening the stator feeding cycle time and the stator feeding beat.
