TECHNICAL FIELD

[0001] The utility model relates to motor field especially relates to a motor rotor assembly device. BACKGROUND

[0002] In the motor manufacturing field, the accurate assembly of the stator and rotor of the motor is one of the key steps to ensure the performance of the motor. The traditional automatic stator-rotor assembly machine is mainly used to realize the automation operation of this key step, aiming to reduce manual intervention and improve production efficiency. However, most of such devices on the market still have certain limitations in actual application.

[0003] Although the existing automatic stator-rotor assembly machine can realize the automatic assembly process of the rotor and the stator to a certain extent, manual placement of the rotor and the stator at the specified position on the machine is still required in the initial loading stage. Specifically, the operator must stand beside the machine and manually place the rotor and the stator every time the assembly operation is performed, and then start the machine to proceed to the next assembly process. The main problems caused by this operation mode are as follows: since a dedicated person is required to load the materials every time, the demand for human resources is increased, and long-time manual placement work is easy to cause worker fatigue, which may affect the accuracy and consistency of the work. Moreover, the speed of manual placement of components is limited, which leads to the fact that the efficiency of the entire production line cannot be significantly improved. SUMMARY

[0004] Therefore, the utility model provides a motor rotor assembly device, which can solve the problem that the existing automatic stator-rotor assembly machine requires a dedicated person to load materials every time, which not only increases the demand for human resources, but also causes worker fatigue due to long-time manual placement work. Moreover, the speed of manual placement of components is limited, which leads to the fact that the efficiency of the entire production line cannot be significantly improved.

[0005] The technical solution is as follows: A motor rotor assembly device includes a support platform, a connecting frame, and a hydraulic cylinder. A limiting groove is formed on the top of the support platform. The connecting frame is connected to the support platform, and a hydraulic cylinder is installed on the connecting frame. Connecting platforms are symmetrically arranged on the sides of the support platform. A storage frame is installed on the top of one of the connecting platforms, where stators are stacked and placed. A pushing mechanism is also provided on the top of the connecting platform on the same side, used to push the stators in the storage frame into the limiting groove of the support platform for loading. A storage cylinder for stacking rotors is installed on the connecting frame. A limiting frame is also installed on the connecting frame, with a slide rail at the bottom of the limiting frame. A blocking mechanism is installed on the storage cylinder, used to block the rotors inside the storage cylinder. A pushing mechanism is installed on the limiting frame, used to push the rotors that fall on the limiting frame into the bottom of the telescopic rod of the hydraulic cylinder. A cylinder is installed inside the support platform, used to hold the rotors in place. A lifting mechanism is also provided inside the support platform, used to lift the assembled stator and rotor in the limiting groove.

[0006] As a further preferred embodiment, the pushing mechanism includes a first electric push rod and a movable frame. The first electric push rod is also installed on the top of the connecting platform on which the storage frame is installed, and the movable frame is connected to the telescopic rod of the first electric push rod.

[0007] As a further preferred embodiment, the material blocking mechanism includes a guide rod, a baffle, and a spring. The guide rod is installed on the outer wall of the storage cylinder, and the baffle is slidably installed on the guide rod. The baffle slides through the storage cylinder and is used to block the rotor inside the storage cylinder. A spring is installed between the baffle and the guide rod.

[0008] As a further preferred embodiment, the pushing mechanism includes a second electric push rod, a push block, a support plate, a first magnetic block, and a second magnetic block. The second electric push rod is mounted on the limiting frame, and the push block is connected to the telescopic rod of the second electric push rod. The support plate is connected to the bottom of the push block, and the support plate is slidably connected to the slide rail. The first magnetic block is connected to the bottom of the baffle, and the second magnetic block is connected to the top of the push block.

[0009] As a further preferred embodiment, the lifting mechanism includes a third electric push rod and a movable cylinder. The third electric push rod is symmetrically arranged inside the support platform. The movable cylinder is connected between the telescopic rods of the two third electric push rods. The movable cylinder is used to lift the stator and rotor that have been assembled in the limiting groove. The top of the movable cylinder has a through hole for the telescopic rod of the cylinder to extend.

[0010] As a further preferred embodiment, a limiting mechanism is also included, which includes a limiting plate and a spring. The limiting plate is rotatably mounted on the outer wall of the storage cylinder. The limiting plate is used to limit the rotor falling on the limiting frame. A spring is connected between the limiting plate and the outer wall of the storage cylinder.

[0011] The beneficial effects of this utility model are as follows: By adopting automated components such as electric push rods and hydraulic cylinders, this utility model achieves rapid and precise component transfer and assembly, which greatly shortens the time of each assembly cycle, thereby improving the overall efficiency of the production line. It also realizes fully automated operation from automatic feeding of stators and rotors to automatic unloading of final assembled parts, which greatly reduces the reliance on manual operation, lowers labor costs, effectively reduces the labor intensity of workers, and also reduces the risk of operational errors caused by long-term repetitive work.

[0021] It also includes a connecting platform 4, a storage frame 5, a pushing mechanism, a storage cylinder 7, a limiting frame 8, a slide rail 9, a blocking mechanism, a pushing mechanism, a cylinder 12, and a lifting mechanism; the support platform 1 has connecting platforms 4 symmetrically arranged on the left and right sides; a storage frame 5 is installed on the top of the connecting platform 4 on the right side, and the storage frame 5 is used for stacking and feeding stators; a pushing mechanism is also installed on the top of the connecting platform 4 on the right side, which is used to push the stators in the storage frame 5 into the limiting groove 101 of the support platform 1 for feeding, thereby realizing automatic feeding of stators; a storage cylinder 7 for stacking and feeding rotors is installed on the upper rear side of the connecting frame 2; a limiting frame is installed in the middle of the connecting frame 2. 8; The bottom of the limiting frame 8 is provided with a slide rail 9, the length of which is shorter than the length of the limiting frame 8; A material blocking mechanism is installed on the storage cylinder 7 to block the rotor inside the storage cylinder 7; A pushing mechanism is installed on the limiting frame 8 to push the rotor falling on the limiting frame 8 into the bottom of the telescopic rod of the hydraulic cylinder 3, thereby realizing automatic feeding of the rotor; A cylinder 12 is installed in the middle of the inner side of the support platform 1 to hold the rotor; A lifting mechanism is also provided on the inner side of the support platform 1 to lift the assembled stator and rotor in the limiting groove 101 so that the assembled stator and rotor can be discharged.

[0022] See Figure 1 and Figure 2 As shown, the pushing mechanism includes a first electric push rod 601 and a movable frame 602; the first electric push rod 601 is also installed on the top of the connecting platform 4 on the right side, and the first electric push rod 601 is located at the lower right of the storage frame 5; the movable frame 602 is connected to the telescopic rod of the first electric push rod 601, and the movable frame 602 can be moved to the left by the first electric push rod 601 driving the movable frame 602 to push the stator at the bottom of the storage frame 5 to the left.

[0023] See Figures 3-5 As shown, the material blocking mechanism includes a guide rod 1001, a baffle 1002, and a spring 1003; the guide rod 1001 is installed on the lower left side of the storage cylinder 7; the baffle 1002 is slidably installed on the guide rod 1001, the baffle 1002 slides through the storage cylinder 7, and the baffle 1002 is used to block the rotor inside the storage cylinder 7; the spring 1003 is installed between the baffle 1002 and the guide rod 1001.

[0024] See Figures 3-5As shown, the pushing mechanism includes a second electric push rod 1101, a push block 1102, a support plate 1103, a first magnetic block 1104, and a second magnetic block 1105. The second electric push rod 1101 is installed on the left side of the limiting frame 8. The push block 1102 is connected to the telescopic rod of the second electric push rod 1101. The support plate 1103 is connected to both the front and rear sides of the bottom of the push block 1102. The support plate 1103 is slidably connected to the slide rail 9 and is used to support the rotor. The bottom of the baffle 1002 is connected to the first magnetic block 1104. The top of the push block 1102 is connected to the second magnetic block 1105. The first magnetic block 1104 and the second magnetic block 1105 are in contact, so that the first magnetic block 1104 and the second magnetic block 1105 can be attracted to each other. Thus, when the push block 1102 moves, it can drive the baffle 1002 to move through the first magnetic block 1104 and the second magnetic block 1105.

[0025] See Figure 6 As shown, the lifting mechanism includes a third electric push rod 1301 and a movable cylinder 1302; the third electric push rod 1301 is symmetrically arranged on the inner side of the support platform 1; the movable cylinder 1302 is connected between the telescopic rods of the two third electric push rods 1301. The movable cylinder 1302 is used to lift the stator and rotor that have been assembled in the limiting groove 101. A through hole is opened in the middle of the top of the movable cylinder 1302, and the through hole is used for the telescopic rod of the cylinder 12 to extend.

[0026] See Figure 3 As shown, it also includes a limiting mechanism, which includes a limiting plate 14 and a spring piece 15; the limiting plate 14 is rotatably installed on the lower front side of the storage cylinder 7, and the limiting plate 14 is used to limit the rotor falling on the limiting frame 8 to prevent the rotor falling on the limiting frame 8 from tipping over; a spring piece 15 is connected between the upper front side of the limiting plate 14 and the lower front side of the storage cylinder 7.

[0027] In the initial state, the second magnetic block 1105 uses magnetic force to hold the first magnetic block 1104, which restricts the position of the baffle 1002 and causes the baffle 1002 to compress the spring 1003, so that the spring 1003 is in a compressed state.

[0028] In use, a suitable number of stators are stacked and placed into the storage frame 5, with the bottom stator resting on top of the connecting platform 4 on the right. Then, a suitable number of rotors are stacked and placed into the storage cylinder 7, with the bottom rotor resting in the limiting frame 8 and supported by the support plate 1103. During this process, as the rotor falls into the limiting frame 8, the limiting plate 14 will limit its movement, preventing it from tipping over. Then, the third electric push rod 1301 drives the movable cylinder 1302 upwards until its top surface is flush with the top surface of the support platform 1. Next, the first electric push rod 601 drives the movable frame 602 to move to the left, bringing it into contact with the bottom stator. The movable frame 602 pushes the lowest stator to the left (the remaining stators are limited by the storage frame 5, so they remain inside the storage frame 5) until the lowest stator is pushed to the top surface of the movable cylinder 1302 and flush with the limiting groove 101. During this process, as the movable frame 602 pushes the lowest stator to the left, it supports the remaining stators inside the storage frame 5. Then, the third electric push rod 1301 drives the movable cylinder 1302 to move downwards and reset, causing the lowest stator to fall into the limiting groove 101. Next, the first electric push rod 601 drives the movable frame 602 to move to the right and reset, separating the movable frame 602 from the lowest stator. When the movable frame 602 and the remaining stators inside the storage frame 5 are separated, the movable frame 602 and the storage frame 5 are aligned. When the stator separates, the next stator in the storage frame 5 will fall down to the top of the connecting platform 4 on the right, thus preparing for the next stator loading. Then, the second electric push rod 1101 drives the push block 1102 and the support plate 1103 to move forward, causing the push block 1102 to push the lowest rotor forward. The first magnetic block 1104 on the push block 1102, through magnetic attraction, drives the second magnetic block 1105 and the baffle 1002 to move forward. The spring 1003 gradually returns to its original state. When the baffle 1002 contacts the remaining rotor in the storage cylinder 7, the baffle 1002 will prevent the remaining rotor in the storage cylinder 7 from falling. The spring 1003 can limit the baffle 1002 to a certain extent, preventing it from falling. When the stop plate 1002 shifts, the lowest rotor moves forward, pressing the limiting plate 14 to rotate. The spring 15 deforms. When the lowest rotor separates from the limiting plate 14, the push block 1102 continues to press the limiting plate 14 to rotate until the lowest rotor moves forward directly below the telescopic rod of the hydraulic cylinder 3. During this process, when the stop plate 1002 moves forward to the foremost end of the guide rod 1001, the stop plate 1002 stops moving due to the restriction of the storage cylinder 7, causing the first magnetic block 1104 to also stop moving. Then, as the push block 1102 drives the second magnetic block 1105 to continue moving forward, the second magnetic block 1105 separates from the first magnetic block 1104. When the lowest rotor moves forward directly below the telescopic rod of the hydraulic cylinder 3...The extension rod of hydraulic cylinder 3 is extended until it contacts the top of the lowest rotor. Simultaneously, the extension rod of pneumatic cylinder 12 is extended until it passes through the through hole of movable cylinder 1302 and the stator, contacting the bottom of the lowest rotor. This clamps the lowest rotor with the extension rods of hydraulic cylinder 3 and pneumatic cylinder 12. Then, the second electric push rod 1101 drives the push block 1102 and support plate 1103 to move backward and reset, separating the push block 1102 from the lowest rotor. The push block 1102 causes the first magnetic block 1104 to move backward and reset. When the push block 1102 separates from the limiting plate 14, the spring 15 returns to its original state, and the spring 15 causes the limiting plate 14 to reverse and reset. When the first magnetic block 1104 contacts the second magnetic block 1105, the first magnetic block 1104 will drive the second magnetic block 1105 and the baffle 1002 to move backward through the magnetic attraction. The spring 1003 gradually compresses, causing the baffle 1002 to separate from the remaining rotor in the storage cylinder 7, thereby causing the baffle 1102 to move backward. 002 no longer obstructs the remaining rotor in the storage cylinder 7 from falling, thus allowing the next rotor in the storage cylinder 7 to fall down into the limiting frame 8, preparing for the next rotor loading. Then, the extension rod of the hydraulic cylinder 3 is controlled to continue extending, while the extension rod of the pneumatic cylinder 12 is controlled to shorten, causing the extension rods of the hydraulic cylinder 3 and the pneumatic cylinder 12 to clamp the rotor and move it downwards until the rotor is brought into the middle of the stator to complete the assembly. Then, the extension rod of the hydraulic cylinder 3 is controlled to shorten and return to its original position, and the extension rod of the pneumatic cylinder 12 is controlled to shorten and return to its original position. The above operation is repeated to automatically feed and assemble the stator and rotor. When the movable cylinder 1302 moves upward again, it will lift the assembled stator and rotor in the limiting groove 101. When the next stator is pushed to the left by the movable frame 602 to the top of the movable cylinder 1302, the next stator will push the previously assembled stator and rotor to the left to the connecting platform 4 on the left for unloading. In this way, the assembled stator and rotor can be automatically unloaded.
