Detailed implementation manners

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. On the contrary, the present invention covers any alternatives, modifications, equivalent methods and solutions made within the spirit and scope of the present invention defined by the claims.

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

[0031] Such as Figure 1An automatic spring-loaded insertion device for rotor magnets as shown includes a frame 1. The frame 1 serves as the basic structure of the entire automatic spring-loaded insertion device for rotor magnets, playing a role in supporting various components. On the frame 1, there are respectively arranged a magnet loading station 2, a magnet transfer station 3, and a magnet insertion station 4. In this embodiment, the number of the magnet loading station 2, the magnet transfer station 3, and the magnet insertion station 4 on the frame 1 is set to two groups each, which can simultaneously perform the operation of inserting magnets into two rotors, improving work efficiency.

[0032] The magnet loading station 2 is responsible for the initial transportation of magnets. On the magnet loading station 2, there is a conveyor belt 5, and a first driving mechanism for driving the continuous transmission of the conveyor belt 5 and sequentially transporting the magnets on the conveyor belt 5 to the designated picking position. The first driving mechanism can be set as a servo motor. Baffle plates can be arranged on both sides of the conveyor belt 5 to ensure that the magnets are transported in an orderly manner and prevent the magnets from shifting or falling during transportation.

[0033] As Figure 1 、 Figures 5 to 8 shown, the magnet insertion station 4 is responsible for installing the magnets into the magnet slots of the rotor. On the magnet insertion station 4, there is a magnet mold 12. A through hole 13 corresponding to the rotor magnet slot is opened on the magnet mold 12. The magnet mold 12 can be replaced according to the different sizes and specifications of the rotor magnet slots to ensure that the through hole 13 is adapted to the rotor magnet slot, that is, adapted to the magnet. Below the magnet mold 12, there is a tray 15 for placing the rotor, and a fourth driving mechanism 16 for driving the tray 15 to reciprocate in the longitudinal direction. The fourth driving mechanism 16 can be set as a cylinder or a servo motor; above the magnet mold 12, there is a pressure plate 17, and a fifth driving mechanism 18 for driving the pressure plate 17 to reciprocate in the longitudinal direction. The fifth driving mechanism 18 can be set as a cylinder or a servo motor. A first pressure rod 19 corresponding to the through hole 13 is arranged on the pressure plate 17. Driven by the fourth driving mechanism 16 and the fifth driving mechanism 18, the tray 15 drives the rotor, and the pressure plate 17 drives the first pressure rod 19 to move towards the magnet mold 12 respectively, and the magnet in the through hole 13 of the magnet mold 12 is inserted into the magnet slot of the rotor through the first pressure rod 19.

[0034] As Figures 1 to 3 shown, the magnet transfer station 3 is responsible for transferring the magnets at the magnet loading station 2 to the magnet insertion station 4. On the magnet transfer station 3, there are a first magnet bin 6 and a second magnet bin 7. A first push rod 8 is arranged at one end of the first magnet bin 6, and a second push rod 9 is arranged at one end of the second magnet bin 7.

[0035] As Figure 1 、 Figure 2 and Figure 4As shown in the figure, a gripper 10 is provided on the frame 1, and a second driving mechanism 11 for driving the gripper 10 to reciprocate between the conveyor belt 5 and the first magnet bin 6. The magnet transported to the designated material-taking position on the conveyor belt 5 is grasped by the gripper 10, and under the drive of the second driving mechanism 11, the magnet is transferred to the first magnet bin 6, thus completing the first step of transfer. To improve work efficiency, the number of magnets grasped by the gripper 10 at one time can be the same as the number of rotor magnet slots.

[0036] As Figure 1 , Figure 2 and Figure 4 shown, in this embodiment, to realize the installation of the gripper 10 and the drive of the gripper 10 by the second driving mechanism 11, a first guide rail 20 is arranged on the frame 1 along the X-axis direction, a second guide rail 21 is arranged along the Y-axis direction, and a third guide rail 22 is arranged along the Z-axis direction. A first fixing plate 23 is arranged on the third guide rail 22, and a sixth driving mechanism 24 for driving the gripper 10 to clamp or release the magnet is arranged on the first fixing plate 23. The gripper 10 is connected to the output shaft of the sixth driving mechanism 24, and the sixth driving mechanism 24 can be set as a thumb cylinder. When the gripper 10 is at the designated material-taking position on the conveyor belt 5, the sixth driving mechanism 24 drives the gripper 10 to clamp the magnet; when the gripper 10 is at the first magnet bin 6, the sixth driving mechanism 24 drives the gripper 10 to release the magnet.

[0037] The second driving mechanism 11 includes a first driving motor 25 arranged on the first guide rail 20 and used for driving the second guide rail 21 to reciprocate along the X-axis direction, a second driving motor 26 arranged on the second guide rail 21 and used for driving the third guide rail 22 to reciprocate along the Y-axis direction, and a third driving motor 27 arranged on the third guide rail 22 and used for driving the first fixing plate 23 to reciprocate along the Z-axis direction. Under the combined drive of the first driving motor 25, the second driving motor 26 and the third driving motor 27, the movement of the gripper 10 in the X-axis, Y-axis, and Z-axis directions can be realized. According to the route set by the program, the gripper 10 can be accurately moved to the designated material-taking position on the conveyor belt 5, grasp the magnet and then move to the first magnet bin 6, place the magnet and then move to the designated material-taking position on the conveyor belt 5 again to grasp the magnet, and so on, to ensure the continuity of magnet feeding.

[0038] As Figure 2 and Figure 4As shown in the figure, a first storage tank 28 for placing magnets is provided inside the first magnet bin 6. A first opening 29 corresponding to the air gripper 10 is provided on the upper surface of the first magnet bin 6. The magnet grasped by the air gripper 10 enters the first storage tank 28 from the first opening 29. At this time, the first opening 29 is the feed inlet of the first magnet bin 6. A second opening 30 is provided on one end face of the first magnet bin 6 facing the first push rod 8, and a third opening 31 is provided on the end face of the first magnet bin 6 away from the first push rod 8. The first opening 29, the second opening 30, and the third opening 31 are all communicated with the first storage tank 28. A seventh driving mechanism 32 for driving the first push rod 8 to move along the axial direction of the first storage tank 28 is provided on the frame 1. The seventh driving mechanism 32 can be set as a cylinder or a servo motor. Driven by the seventh driving mechanism 32, the first push rod 8 is inserted from the second opening 30 of the first magnet bin 6, and the magnet in the first storage tank 28 is pushed out from the third opening 31. At this time, the third opening 31 is the discharge outlet of the first magnet bin 6. The first magnet bin 6 can be replaced according to different magnet sizes and specifications to ensure that the first storage tank 28, the first opening 29, the second opening 30, and the third opening 31 are respectively adapted to the magnets.

[0039] As Figures 1 to 3 shown in the figure, a third driving mechanism 14 for driving the second magnet bin 7 to reciprocate between the first magnet bin 6 and the magnet mold 12 is provided on the frame 1. A second fixing plate 33 is provided on the output shaft of the third driving mechanism 14. The second magnet bin 7 and the second push rod 9 are both provided on the second fixing plate 33. The third driving mechanism 14 can be set as a rotary cylinder. Driven by the third driving mechanism 14, the second fixing plate 33 drives the second magnet bin 7 and the second push rod 9 to rotate 0 to 180° in the circumferential direction.

[0040] A second storage tank 34 for placing magnets is provided inside the second magnet bin 7. A fourth opening is provided on one end face of the second magnet bin 7 facing the second push rod 9, and a fifth opening 35 is provided on the end face of the second magnet bin 7 away from the second push rod 9. The fourth opening and the fifth opening 35 are both communicated with the second storage tank 34. When the third driving mechanism 14 drives the second fixing plate 33 to drive the second magnet bin 7 to rotate to the position of the first magnet bin 6, the fifth opening 35 is opposite to the third opening 31, and the magnet pushed out by the first push rod 8 enters the second storage tank 34 from the fifth opening 35. At this time, the fifth opening 35 is the feed inlet of the second magnet bin 7.

[0041] One end of the second magnet bin 7 facing the fifth opening 35 is also provided with a sixth opening 38. The sixth opening 38 runs through the second magnet bin 7 in the longitudinal direction, and the sixth opening 38 is respectively communicated with the second storage tank 34, the fourth opening, and the fifth opening 35. A second pressure rod 39 corresponding to the sixth opening 38 and a ninth driving mechanism 40 for driving the second pressure rod 39 to move along the axial direction of the sixth opening 38 are arranged on the second fixing plate 33. The second pressure rod 39 is located above the second magnet bin 7, and the ninth driving mechanism 40 can be set as a cylinder or a servo motor. A first inductor 36 corresponding to the second push rod 9 and an eighth driving mechanism 37 for driving the second push rod 9 to move along the axial direction of the second storage tank 34 are also arranged on the second fixing plate 33. The eighth driving mechanism 37 can be set as a cylinder or a servo motor.

[0042] As Figure 1 , Figure 3 , Figure 5 and Figure 6 shown, when the third driving mechanism 14 drives the second fixing plate 33 to drive the second magnet bin 7 to rotate to the magnet mold 12, the sixth opening 38 corresponds to the through hole 13 on the magnet mold 12. Driven by the eighth driving mechanism 37, the second push rod 9 is inserted from the fourth opening of the second magnet bin 7, and the magnets in the second storage tank 34 are pushed towards the fifth opening 35, so that the neatly arranged magnets are sequentially transferred to the position corresponding to the sixth opening 38. Then, driven by the ninth driving mechanism 40, the second pressure rod 39 is inserted from the upper end of the sixth opening 38, and the magnets in the second storage tank 34 that are transferred to the position corresponding to the sixth opening 38 are pushed out from the lower end of the sixth opening 38, so that they enter the through hole 13 of the magnet mold 12. Thus, the transfer of the second step is completed. At this time, the sixth opening 38 is the discharge port of the second magnet bin 7. The first inductor 36 can sense the displacement position of the second push rod 9 and transmit the sensed data to the eighth driving mechanism 37 and the ninth driving mechanism 40, which can ensure that the pushing distance of the second push rod 9 each time is the position of one magnet, and ensure the orderliness and continuity of the magnet transportation. The second magnet bin 7 can be replaced according to different magnet sizes and specifications to ensure that the second storage tank 34, the fourth opening, the fifth opening 35, and the sixth opening 38 are respectively adapted to the magnets.

[0043] As Figure 3As shown, to prevent the magnets in the second storage tank 34 from falling out through the fifth opening 35 during the pushing process of the second push rod 9, a stopper 41 is movably arranged in the second storage tank 34, and the stopper 41 is located between the sixth opening 38 and the fifth opening 35. A first guiding inclined surface is arranged on the side of the stopper 41 facing the fifth opening 35. A first elastic member is arranged between the stopper 41 and the inner surface of the second storage tank 34, and the first elastic member is set as a compression spring. The outer surface of the magnet contacts the first guiding inclined surface and presses the stopper 41, so that the magnet can enter the second storage tank 34 from the fifth opening 35. At this time, the first elastic member is in a contracted and deformed state; when the magnet enters the interior of the second storage tank 34, the stopper 41 resets under the elastic force of the first elastic member, blocking the magnet located inside the second storage tank 34, so that the magnet can enter through the fifth opening 35 but cannot come out through the fifth opening 35, and can only be discharged through the sixth opening 38 under the pushing of the second pressing rod 39.

[0044] As Figure 1 and Figure 5 shown, a third fixing plate 42 is arranged on the frame 1, and a tenth driving mechanism 43 for driving the third fixing plate 42 to move horizontally is provided. The tenth driving mechanism 43 can be set as a cylinder or a servo motor. A eleventh driving mechanism for driving the magnet mold 12 to rotate 0 - 360° along its circumferential direction is arranged on the third fixing plate 42. The magnet mold 12 is connected to the output end of the eleventh driving mechanism and is rotationally matched with the third fixing plate 42. The eleventh driving mechanism can be set as a rotary cylinder or a servo motor.

[0045] As Figure 3 、 Figure 5 、 Figure 6 and Figure 7 shown, due to the short output shafts and short driving paths of the fourth driving mechanism 16 and the fifth driving mechanism 18, the space between the tray 15 and the pressing plate 17 is limited, which is not convenient for the second magnet bin 7 to extend between the tray 15 and the pressing plate 17 to perform the operation of initially guiding the magnets into the magnet mold 12. Therefore, it is necessary to first drive the third fixing plate 42 by the tenth driving mechanism 43 to drive the magnet mold 12 to move horizontally to a specified position to ensure that the second magnet bin 7 has enough space to complete the operation of initially guiding the magnets. During the initial guiding of the magnets, the eleventh driving mechanism drives the magnet mold 12 to rotate, so that the through holes 13 on the magnet mold 12 move below the sixth opening 38 in turn, and the magnets can enter each through hole 13 from the sixth opening 38. After all the through holes 13 have completed the initial guiding of the magnets, the tenth driving mechanism 43 drives the third fixing plate 42 to drive the magnet mold 12 back between the tray 15 and the pressing plate 17.

[0046] As Figure 6As shown, a top block 44 is disposed in each through hole 13 of the magnet steel mold 12. A second guiding inclined surface 45 is provided on the upper surface of the top block 44. A second elastic member is disposed between the top block 44 and the inner surface of the through hole 13, and the second elastic member is a compression spring. The outer surface of the magnet steel contacts the second guiding inclined surface 45 and presses the top block 44, so as to facilitate the magnet steel to enter the through hole 13. At this time, the second elastic member is in a contracted and deformed state; after the magnet steel enters the interior of the through hole 13, the top block 44 presses the magnet steel under the elastic force of the first elastic member to prevent the magnet steel from falling off.

[0047] As Figure 1 , Figure 6 and Figure 7 shown, a fourth fixing plate 46 is provided on the frame 1. The fourth driving mechanism 16 is disposed on the fourth fixing plate 46. The tray 15 is connected to the output shaft of the fourth driving mechanism 16. The fourth driving mechanism 16 can be a cylinder or a servo motor. The upper surface of the tray 15 contacts the rotor, that is, the rotor is placed on the tray 15. To make the magnet steel grooves on the rotor correspond to the through holes 13 on the magnet steel mold 12 one by one, a mark corresponding to one of the magnet steel grooves can be provided on the outer surface of the rotor, and a mark is also provided on the upper surface of the tray 15. When placing the rotor, make the two marks correspond to each other.

[0048] To support the tray 15 and ensure the accuracy of the tray 15 during longitudinal movement, a first guiding rod 47 is provided on the lower surface of the tray 15 along the driving direction of the fourth driving mechanism 16. A first guiding hole for the first guiding rod 47 to pass through is formed on the fourth fixing plate 46, and a first guiding ring 48 slidably engaged with the first guiding rod 47 is disposed in the first guiding hole.

[0049] As Figure 1 , Figure 6 , Figure 8 and Figure 9As shown, the fifth driving mechanism 18 is arranged on the frame 1, and the pressure plate 17 is connected to the output end of the fifth driving mechanism 18. The fifth driving mechanism 18 can be set as a servo motor or a cylinder. A material guiding plate 49 is arranged below the pressure plate 17, and a second guiding hole 50 for the lower end of the first pressure rod 19 to pass through is formed in the material guiding plate 49. To support the pressure plate 17 and the material guiding plate 49 and ensure the accuracy of the pressure plate 17 and the material guiding plate 49 during the longitudinal movement, a second guiding rod 51 is arranged on the upper surface of the material guiding plate 49 along the driving direction of the fifth driving mechanism 18. A third guiding hole for the second guiding rod 51 to pass through is formed in the pressure plate 17, and a second guiding ring 52 slidably matched with the second guiding rod 51 is arranged in the third guiding hole. A first limiting member 53 and a third elastic member 54 are sleeved on the second guiding rod 51 respectively. The first limiting member 53 is located above the pressure plate 17, and the third elastic member 54 is located between the pressure plate 17 and the material guiding plate 49. The third elastic member 54 is set as a compression spring.

[0050] The fifth driving mechanism 18 drives the pressure plate 17 to drive the material guiding plate 49 to move downward synchronously in the longitudinal direction. When the lower surface of the material guiding plate 49 contacts the upper surface of the magnet mold 12, the fifth driving mechanism 18 continuously drives the pressure plate 17 to press down, so that the lower end of the first pressure rod 19 passes through the second guiding hole 50, contacts the magnet on the through hole 13, and drives the magnet into the magnet groove of the rotor to complete the final installation and introduction of the magnet. At this time, the third elastic member 54 is in a contracted and deformed state. By setting the third elastic member 54, the rigid impact between the material guiding plate 49 and the magnet mold 12 can be avoided, and wear can be caused.

[0051] As Figures 8 to 11 shown, a fourth guiding hole for the upper end of the first pressure rod 19 to pass through is formed in the pressure plate 17, and a third guiding ring 55 slidably matched with the first pressure rod 19 is arranged in the fourth guiding hole. A second limiting member 56, a third limiting member 57 and a fourth elastic member 58 are sleeved on the first pressure rod 19 respectively. The second limiting member 56 is located above the pressure plate 17, the third limiting member 57 is located below the pressure plate 17, and the fourth elastic member 58 is located between the pressure plate 17 and the third limiting member 57. The fourth elastic member 58 is set as a compression spring, and a second inductor 59 corresponding to the first pressure rod 19 is arranged on the upper surface of the pressure plate 17.

[0052] If the automatic spring-loaded introduction device of the rotor magnetic steel fails, the first pressing rod 19 provided on the pressing plate 17, the second guide hole 50 provided on the guide plate 49, the through hole 13 provided on the magnetic steel mold 12, and the magnetic steel slot provided on the rotor do not correspond to each other one by one, 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 to contact the magnetic steel, but conflicts with the upper surface of the magnetic steel mold 12, or after passing through the through hole 13 and driving the magnetic steel to be pressed down, it does not enter the magnetic steel slot 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 through the second sensor 59 that at this time, in the rotor where the magnetic steel is being introduced, there is a situation where the magnetic steel is not introduced into a certain magnetic steel slot, and rework is required. The elastic pressure introduction of the magnetic steel by the first pressing rod 19 is realized by the fourth elastic member 58, so that the rigid impact between the magnetic steel and the magnetic steel mold 12 and the rotor can be avoided, which causes the wear of the rotor and the magnetic steel, and is beneficial to improving the quality of the rotor.

[0053] The above describes the embodiments of the present invention in detail in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. For ordinary technicians in this field, several modifications and improvements can be made without departing from the present invention, and these should also be regarded as belonging to the protection scope of the present invention.
