DETAILED DESCRIPTION

[0029] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention. On the contrary, the present invention encompasses any alternatives, modifications, equivalent methods and solutions made within the spirit and scope of the present invention as defined by the claims.

[0030] Furthermore, in order to provide the public with a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention, but those skilled in the art can fully understand the present invention without the description of these details.

[0031] like Figure 1The illustrated automatic rotor magnet spring-loaded introduction device includes a frame 1, which serves as the foundational structure for the entire rotor magnet spring-loaded introduction device and supports various components. Frame 1 is provided with a magnet loading station 2, a magnet transfer station 3, and a magnet introduction station 4. In this embodiment, the frame 1 includes two groups of magnet loading stations 2, magnet transfer stations 3, and magnet introduction stations 4, enabling simultaneous magnet introduction for two rotors and improving work efficiency.

[0032] The magnet loading station 2 is responsible for the initial conveying of the magnets. It is equipped with a conveyor belt 5 and a first drive mechanism, which can be a servo motor, for continuously driving the conveyor belt 5 and transporting the magnets on the conveyor belt 5 to a designated pick-up location. Baffles can be installed on both sides of the conveyor belt 5 to ensure the orderly arrangement of the magnets during conveyance and prevent them from shifting or falling during transportation.

[0033] like Figure 1 、 Figures 5 to 8 As shown, the magnet introduction station 4 is responsible for installing the magnets into the magnet slots of the rotor. A magnet mold 12 is provided on the magnet introduction station 4. The magnet mold 12 has through holes 13 corresponding to the rotor magnet slots. The magnet mold 12 can be replaced according to the size and specifications of the rotor magnet slots to ensure that the through holes 13 are compatible with the rotor magnet slots, that is, compatible with the magnets. Below the magnet mold 12, there is a tray 15 for placing the rotor, and a fourth drive mechanism 16 for driving the tray 15 to reciprocate in the longitudinal direction. The fourth drive mechanism 16 can be configured as a cylinder or a servo motor. Above the magnet mold 12, there is a press plate 17 and a fifth drive mechanism 18 for driving the press plate 17 to reciprocate in the longitudinal direction. The fifth drive mechanism 18 can be configured as a cylinder or a servo motor. The press plate 17 is provided with a first press rod 19 corresponding to the through hole 13. Driven by the fourth drive mechanism 16 and the fifth drive mechanism 18, the tray 15 drives the rotor and the pressing plate 17 drives the first pressing rod 19 to move toward the magnetic steel mold 12 respectively, and the magnetic steel located in the through hole 13 of the magnetic steel mold 12 is introduced into the magnetic steel slot of the rotor through the first pressing rod 19.

[0034] like Figures 1 to 3 As shown, the magnetic steel transfer station 3 is responsible for transferring the magnetic steel at the magnetic steel loading station 2 to the magnetic steel import station 4. A first magnetic steel silo 6 and a second magnetic steel silo 7 are provided on the magnetic steel transfer station 3. A first push rod 8 is provided at one end of the first magnetic steel silo 6, and a second push rod 9 is provided at one end of the second magnetic steel silo 7.

[0035] like Figure 1 、 Figure 2 and Figure 4As shown, the frame 1 is equipped with an air gripper 10 and a second drive mechanism 11 for driving the air gripper 10 to reciprocate between the conveyor belt 5 and the first magnetic steel hopper 6. The air gripper 10 grabs the magnetic steel delivered to the designated pick-up position on the conveyor belt 5 and, driven by the second drive mechanism 11, transfers the magnetic steel to the first magnetic steel hopper 6, thus completing the first transfer step. To improve work efficiency, the number of magnetic steels that the air gripper 10 can grab at a time can be the same as the number of magnetic steel slots in the rotor.

[0036] like Figure 1 、 Figure 2 and Figure 4 As shown, in this embodiment, to facilitate the installation of the air gripper 10 and the actuation of the air gripper 10 by the second drive mechanism 11, the frame 1 is provided with a first guide rail 20 along the X-axis, a second guide rail 21 along the Y-axis, and a third guide rail 22 along the Z-axis. A first fixing plate 23 is mounted on the third guide rail 22. A sixth drive mechanism 24, which is used to drive the air gripper 10 to clamp or release the magnetic steel, is mounted on the first fixing plate 23. The air gripper 10 is connected to the output shaft of the sixth drive mechanism 24, which can be configured as a thumb cylinder. When the air gripper 10 is at the designated material removal position on the conveyor belt 5, the sixth drive mechanism 24 drives the air gripper 10 to clamp the magnetic steel. When the air gripper 10 is at the first magnetic steel hopper 6, the sixth drive mechanism 24 drives the air gripper 10 to release the magnetic steel.

[0037] The second drive mechanism 11 includes a first drive motor 25, mounted on the first guide rail 20, for driving the second guide rail 21 to reciprocate along the X-axis; a second drive motor 26, mounted on the second guide rail 21, for driving the third guide rail 22 to reciprocate along the Y-axis; and a third drive motor 27, mounted on the third guide rail 22, for driving the first fixed plate 23 to reciprocate along the Z-axis. Driven by the coordinated operation of the first drive motor 25, the second drive motor 26, and the third drive motor 27, the air gripper 10 can move along the X-, Y-, and Z-axes. Following a programmed route, the air gripper 10 precisely moves to a designated pick-up position on the conveyor belt 5, grabs a magnetic steel, and then moves to the first magnetic steel hopper 6. After placing the magnetic steel, it moves again to a designated pick-up position on the conveyor belt 5 to grab the magnetic steel. This reciprocating motion ensures continuous magnetic steel feeding.

[0038] like Figure 2 and Figure 4As shown, a first storage trough 28 for placing magnetic steel is provided inside the first magnetic steel silo 6. A first opening 29 corresponding to the air gripper 10 is provided on the upper surface of the first magnetic steel silo 6. The magnetic steel grasped by the air gripper 10 enters the first storage trough 28 from the first opening 29. At this time, the first opening 29 serves as the feed port of the first magnetic steel silo 6. A second opening 30 is provided on one end surface of the first magnetic steel silo 6 facing the first push rod 8, and a third opening 31 is provided on one end surface of the first magnetic steel silo 6 away from the first push rod 8. The first opening 29, the second opening 30, and the third opening 31 are all connected to the first storage trough 28. A seventh driving mechanism 32 is provided on the frame 1 for driving the first push rod 8 to move along the axial direction of the first storage trough 28. The seventh driving mechanism 32 can be configured as a cylinder or a servo motor. Driven by the seventh drive mechanism 32, the first push rod 8 is inserted through the second opening 30 of the first magnetic steel silo 6, pushing the magnetic steel in the first storage trough 28 out of the third opening 31. At this time, the third opening 31 serves as the discharge port of the first magnetic steel silo 6. The first magnetic steel silo 6 can be replaced according to the size and specifications of the magnetic steel to ensure that the first storage trough 28, the first opening 29, the second opening 30, and the third opening 31 are respectively compatible with the magnetic steel.

[0039] like Figures 1 to 3 As shown, the frame 1 is provided with a third drive mechanism 14 for driving the second magnetic steel hopper 7 to reciprocate between the first magnetic steel hopper 6 and the magnetic steel mold 12. A second fixed plate 33 is provided on the output shaft of the third drive mechanism 14. The second magnetic steel hopper 7 and the second push rod 9 are both provided on the second fixed plate 33. The third drive mechanism 14 can be configured as a rotary cylinder. Driven by the third drive mechanism 14, the second fixed plate 33 drives the second magnetic steel hopper 7 and the second push rod 9 to rotate 0 to 180 degrees in the circumferential direction.

[0040] A second storage trough 34 for storing magnetic steel is defined within the second magnetic steel silo 7. A fourth opening is defined on one end surface of the second magnetic steel silo 7 facing the second push rod 9. A fifth opening 35 is defined on one end surface of the second magnetic steel silo 7 away from the second push rod 9. Both the fourth and fifth openings 35 are connected to the second storage trough 34. When the third driving mechanism 14 drives the second fixed plate 33 to rotate the second magnetic steel silo 7 to the first magnetic steel silo 6, the fifth opening 35 is opposite to the third opening 31, and the magnetic steel pushed out by the first push rod 8 enters the second storage trough 34 through the fifth opening 35. At this time, the fifth opening 35 serves as the feed port of the second magnetic steel silo 7.

[0041] The second magnetic steel silo 7 is further provided with a sixth opening 38 at one end thereof facing the fifth opening 35. The sixth opening 38 penetrates the second magnetic steel silo 7 in the longitudinal direction, and the sixth opening 38 is respectively connected to the second storage trough 34, the fourth opening, and the fifth opening 35. The second fixed plate 33 is provided with a second pressing rod 39 corresponding to the sixth opening 38, and a ninth driving mechanism 40 for driving the second pressing rod 39 to move in the axial direction of the sixth opening 38. The second pressing rod 39 is located above the second magnetic steel silo 7. The ninth driving mechanism 40 can be configured as a cylinder or a servo motor. The second fixed plate 33 is also provided with a first sensor 36 corresponding to the second push rod 9, and an eighth driving mechanism 37 for driving the second push rod 9 to move in the axial direction of the second storage trough 34. The eighth driving mechanism 37 can be configured as a cylinder or a servo motor.

[0042] like Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, when the third driving mechanism 14 drives the second fixed plate 33 to rotate the second magnetic steel hopper 7 to the magnetic steel mold 12, the sixth opening 38 corresponds to the through hole 13 on the magnetic steel mold 12. Under the drive of the eighth driving mechanism 37, the second push rod 9 is inserted from the fourth opening of the second magnetic steel hopper 7, pushing the magnetic steel in the second storage trough 34 toward the fifth opening 35, so that the neatly arranged magnetic steel is sequentially transferred to the position corresponding to the sixth opening 38. Then, under the drive of the ninth driving mechanism 40, the second pressing rod 39 is inserted from the upper end of the sixth opening 38, pushing the magnetic steel in the second storage trough 34 that has been transferred to the position corresponding to the sixth opening 38 from the lower end of the sixth opening 38, so that it enters the through hole 13 of the magnetic steel mold 12, thus completing the second step of transfer. At this time, the sixth opening 38 is the discharge port of the second magnetic steel hopper 7. The first sensor 36 senses the displacement of the second push rod 9 and transmits the sensed data to the eighth and ninth drive mechanisms 37 and 40, ensuring that the second push rod 9 moves the same distance as the position of a magnetic steel each time, ensuring the orderly and continuous transportation of the magnetic steel. The second magnetic steel hopper 7 can be replaced according to the size and specifications of the magnetic steel to ensure that the second storage trough 34, the fourth opening, the fifth opening 35, and the sixth opening 38 are respectively compatible with the magnetic steel.

[0043] like Figure 3As shown, to prevent the magnetic steel in the second material storage trough 34 from falling out of the fifth opening 35 during the pushing process of the second push rod 9, a stopper 41 is movably provided in the second material storage trough 34, and the stopper 41 is located between the sixth opening 38 and the fifth opening 35. A first guide slope is provided on the side of the stopper 41 facing the fifth opening 35, and a first elastic member is provided between the stopper 41 and the inner surface of the second material storage trough 34, and the first elastic member is configured as a compression spring. The outer surface of the magnetic steel contacts the first guide slope and squeezes the stopper 41, so that the magnetic steel enters the second material storage trough 34 from the fifth opening 35. At this time, the first elastic member is in a contracted and deformed state. When the magnetic steel enters the second material storage trough 34, the stopper 41 is reset under the elastic force of the first elastic member, blocking the magnetic steel in the second material storage trough 34, so that the magnetic steel can enter through the fifth opening 35 but cannot exit through the fifth opening 35. The magnetic steel can only be discharged from the sixth opening 38 under the push of the second pressing rod 39.

[0044] like Figure 1 and Figure 5 As shown, the frame 1 is provided with a third fixed plate 42 and a tenth driving mechanism 43 for driving the third fixed plate 42 to move in the horizontal direction. The tenth driving mechanism 43 can be set as a cylinder or a servo motor. The third fixed plate 42 is provided with an eleventh driving mechanism for driving the magnetic steel mold 12 to rotate 0~360° along its own circumferential direction. The magnetic steel mold 12 is connected to the output end of the eleventh driving mechanism and rotates with the third fixed plate 42. The eleventh driving mechanism can be set as a rotating cylinder or a servo motor.

[0045] like Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As shown, due to the shorter output shafts and drive paths of the fourth drive mechanism 16 and the fifth drive mechanism 18, the space between the tray 15 and the pressure plate 17 is limited, making it inconvenient for the second magnetic steel hopper 7 to extend between the tray 15 and the pressure plate 17 to perform the initial introduction of the magnetic steel into the magnetic steel mold 12. Therefore, it is necessary to first drive the third fixed plate 42 through the tenth drive mechanism 43 to drive the magnetic steel mold 12 to move horizontally to the specified position to ensure that the second magnetic steel hopper 7 has enough space to complete the initial introduction of the magnetic steel. During the initial introduction of the magnetic steel, the eleventh drive mechanism drives the magnetic steel mold 12 to rotate so that the through holes 13 on the magnetic steel mold 12 move to the bottom of the sixth opening 38 in turn, and the magnetic steel can enter each through hole 13 from the sixth opening 38. After all through holes 13 have completed the initial introduction of the magnetic steel, the tenth drive mechanism 43 drives the third fixed plate 42 to drive the magnetic steel mold 12 back between the tray 15 and the pressure plate 17.

[0046] like Figure 6As shown, each through-hole 13 of the magnetic steel mold 12 is provided with a top block 44. A second guiding slope 45 is provided on the top surface of the top block 44. A second elastic member, configured as a compression spring, is disposed between the top block 44 and the inner surface of the through-hole 13. The outer surface of the magnetic steel contacts the second guiding slope 45, squeezing the top block 44 to facilitate entry of the magnetic steel into the through-hole 13. At this point, the second elastic member is in a contracted and deformed state. Once the magnetic steel enters the through-hole 13, the top block 44, under the elastic force of the first elastic member, squeezes the magnetic steel to prevent it from falling.

[0047] like Figure 1 、 Figure 6 and Figure 7 As shown, a fourth fixing plate 46 is mounted on the frame 1, and a fourth drive mechanism 16 is mounted on the fourth fixing plate 46. The tray 15 is connected to the output shaft of the fourth drive mechanism 16, which can be configured as a cylinder or a servo motor. The upper surface of the tray 15 contacts the rotor, and the rotor is placed on the tray 15. To ensure a one-to-one correspondence between the magnetic steel slots on the rotor and the through holes 13 in the magnetic steel mold 12, a mark corresponding to one of the magnetic steel slots can be provided on the outer surface of the rotor. A mark can also be provided on the upper surface of the tray 15. When the rotor is placed, the two marks can be aligned.

[0048] In order to support the tray 15 and ensure the accuracy of the tray 15 during the longitudinal movement, a first guide rod 47 is provided on the lower surface of the tray 15 along the driving direction of the fourth driving mechanism 16, and a first guide hole for the first guide rod 47 to pass through is provided on the fourth fixed plate 46, and a first guide ring 48 is provided in the first guide hole to slide with the first guide rod 47.

[0049] like Figure 1 、 Figure 6 、 Figure 8 and Figure 9As shown, the fifth drive mechanism 18 is arranged on the frame 1, and the pressing plate 17 is connected to the output end of the fifth drive mechanism 18. The fifth drive mechanism 18 can be configured as a servo motor or a cylinder. A guide plate 49 is provided below the pressing plate 17. The guide plate 49 is provided with a second guide hole 50 for the lower end of the first pressing rod 19 to pass through. In order to support the pressing plate 17 and the guide plate 49 and to ensure the accuracy of the pressing plate 17 and the guide plate 49 during the longitudinal movement, a second guide rod 51 is provided on the upper surface of the guide plate 49 along the driving direction of the fifth drive mechanism 18. The pressing plate 17 is provided with a third guide hole for the second guide rod 51 to pass through. The third guide hole is provided with a second guide ring 52 that slides with the second guide rod 51. The second guide rod 51 is respectively provided with a first limit member 53 and a third elastic member 54. The first limit member 53 is located above the pressing plate 17. The third elastic member 54 is located between the pressing plate 17 and the guide plate 49. The third elastic member 54 is configured as a compression spring.

[0050] The fifth drive mechanism 18 drives the blank holder 17, which in turn drives the guide plate 49 to move downward in the longitudinal direction. Once the lower surface of the guide plate 49 contacts the upper surface of the magnetic mold 12, the fifth drive mechanism 18 continues to drive the blank holder 17 downward, causing the lower end of the first blank holder 19 to pass through the second guide hole 50, contact the magnetic steel in the through hole 13, and drive the magnetic steel into the magnetic steel slot of the rotor, completing the final installation and introduction of the magnetic steel. At this point, the third elastic member 54 is in a contracted and deformed state. The provision of the third elastic member 54 prevents wear caused by rigid impact between the blank holder 49 and the magnetic mold 12.

[0051] like Figures 8 to 11 As shown, a fourth guide hole is provided on the pressing plate 17 for the upper end of the first pressing rod 19 to pass through, and a third guide ring 55 is provided in the fourth guide hole to slide with the first pressing rod 19. The first pressing rod 19 is respectively provided with a second limit member 56, a third limit member 57 and a fourth elastic member 58. The second limit member 56 is located above the pressing plate 17, the third limit member 57 is located below the pressing plate 17, the fourth elastic member 58 is located between the pressing plate 17 and the third limit member 57, the fourth elastic member 58 is set as a compression spring, and a second sensor 59 corresponding to the first pressing rod 19 is provided on the upper surface of the pressing plate 17.

[0052] If the automatic spring-loaded introduction device of the rotor magnet fails, the first pressing rod 19 set on the pressing plate 17, the second guide hole 50 opened on the guide plate 49, the through hole 13 opened on the magnet mold 12, and the magnet groove opened on the rotor do not correspond to each other, which will cause the first pressing rod 19 to fail to pass through the second guide hole 50 during the pressing process, but to conflict with the upper surface of the guide plate 49, or after passing through the second guide hole 50, it does not enter the through hole 13 and contact the magnet, but conflicts with the upper surface of the magnet mold 12, or after passing through the through hole 13 and driving the magnet to be pressed down, it does not enter the magnet groove of the rotor, but conflicts with the upper surface of the rotor. In any of the above situations, the first pressing rod 19 will be pushed upward in the axial direction, and the operator can be informed by the second sensor 59 that at this time, in the rotor where the magnet is being introduced, there is a magnet groove in which the magnet is not introduced, and rework is required. The elastic pressure introduction of the magnet by the first pressing rod 19 is achieved through the fourth elastic member 58, which can avoid rigid impact between the magnet and the magnet mold 12 and the rotor, causing wear of the rotor and the magnet, and is beneficial to improving the quality of the rotor.

A person skilled in the art may make several modifications and improvements without departing from the present invention, and these should also be considered to fall within the scope of protection of the present invention.
