Abstract
Description
Technical Field
[0001] This utility model relates to the field of micro motor manufacturing, and in particular to a micro motor rotor performance testing device. Background Technology
[0002] Rotor performance testing is a critical process before the micro-motor rotor semi-finished product leaves the production line. Each rotor assembly undergoes 100% performance testing after manufacturing, including five aspects: withstand voltage testing, inter-turn resistance, inter-span resistance, inter-laminar resistance, and welding resistance. These tests are essential for ensuring the quality and performance of the micro-motor rotor.
[0003] However, current rotor performance testing equipment has some significant shortcomings. First, existing equipment only performs a simple classification of defective and good products, without further classifying defective products based on specific performance test results. This makes it impossible for staff to directly determine which specific performance indicator is deficient in a defective product, increasing the difficulty of subsequent processing and analysis. The lack of detailed defect classification not only affects production efficiency but may also make it difficult to accurately pinpoint the root cause of problems, thereby impacting the improvement of overall production quality.
[0004] Secondly, existing methods for testing the performance of micro-motor rotors mainly rely on manual positioning or simple mechanical fixtures, which have significant positioning errors. For example, when using mechanical fixtures to fix the rotor, angular errors or vibrations can easily occur during testing due to the complex shape of the rotor or inaccurate positioning of the fixture itself. These problems directly affect the accuracy and repeatability of performance testing, potentially leading to misjudgments or omissions, and impacting the reliability of product quality control.
[0005] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0033] like Figures 1-9As shown, this embodiment proposes a micro-motor rotor performance testing device, including a frame 1, an operating table 10 mounted on the frame 1, multiple rotor performance testing fixtures 2 mounted on the operating table 10, a good product unloading device 3 and a defective product unloading device 4 mounted on both sides of the frame 1 on the operating table 10, and a robotic arm for clamping and unloading rotors. The rotor performance testing fixture 2 includes a rotor performance testing device 21 mounted on a base 22. The rotor performance testing device 21 has a testing cavity 210 for accommodating the rotor and an opening 211 communicating with the testing cavity 210. The rotor performance testing device 21 is used to perform performance testing on the rotor within the testing cavity 210. The defective product unloading device 4 includes multiple independent defective product unloading tracks 41. Each defective product unloading track 41 corresponds to the performance parameters detected by the rotor performance testing device 21, and each defective product unloading track 41 is configured to receive rotors whose associated performance parameters do not meet the standards. The multiple independent defective product unloading tracks 41 in the defective product unloading device 4 allow each track to receive rotors with specific performance parameters that do not meet the standards. This technical solution achieves product classification by setting up multiple independent defective product unloading tracks 41, each corresponding to a specific performance parameter. This design allows workers to directly determine which performance aspect of the defective product is deficient, improving the efficiency and accuracy of testing. Furthermore, by setting up a robotic arm and rotor performance testing fixture 2, automatic loading and unloading and precise positioning of the rotor are achieved, reducing errors caused by manual operation and improving the repeatability and accuracy of testing. Compared with existing technologies, this technical solution has significant advantages in defective product classification and rotor positioning, effectively solving the technical problems of unclear defective product classification and inaccurate rotor positioning in micro-motor rotor performance testing equipment.
[0034] like Figure 1In further embodiments 2 and 3, the defective product unloading device 4 includes five independent defective product unloading tracks 41. Each defective product unloading track 41 corresponds to the withstand voltage test, inter-turn resistance, inter-span resistance, inter-plate resistance, and welding resistance detected by the rotor performance testing device 21. Specifically, the five independent tracks of the defective product unloading device 4 correspond to different performance testing parameters. The withstand voltage test track is used to receive rotors that fail the withstand voltage test, the inter-turn resistance track is used to receive rotors that fail the inter-turn resistance test, the inter-span resistance track is used to receive rotors that fail the inter-span resistance test, the inter-plate resistance track is used to receive rotors that fail the inter-plate resistance test, and the welding resistance track is used to receive rotors that fail the welding resistance test. Thus, this application achieves this by setting five independent defective product unloading tracks 41, each track corresponding to the withstand voltage test, inter-turn resistance, inter-span resistance, inter-plate resistance, and welding resistance detected by the rotor performance testing device 21. This design enables the defective product unloading device 4 to classify defective products based on rotor performance test results, thus solving the problem in existing technologies where defective products cannot be classified based on performance test results. Through this classification method, workers can directly determine which performance aspect of the defective product is deficient, improving testing efficiency and accuracy. Compared with existing technologies, the technical solution of this application not only improves the accuracy of defective product classification but also reduces the need for manual intervention, thereby reducing the risk of operational errors and improving overall production efficiency. It should be noted that methods for detecting withstand voltage, inter-turn resistance, inter-span resistance, inter-plate resistance, and welding resistance are existing technologies and not part of the innovation of this application; therefore, they will not be described here.
[0035] In a specific implementation, the defective product unloading device 4 includes a conveyor belt 42 and multiple partitions 43 disposed on the conveyor belt 42, which divide the conveyor belt 42 into five independent defective product unloading tracks 41. The conveyor belt 42 is a continuous conveying device used to transport defective products from the inspection area to the sorting area. The partitions 43 are vertical dividers fixed to the conveyor belt 42, used to divide the conveyor belt 42 into multiple independent tracks. This application, through the arrangement of the conveyor belt 42 and the multiple partitions 43, divides the conveyor belt 42 into five independent defective product unloading tracks 41. This design allows each defective product unloading track 41 to correspond to a specific performance parameter detected by the rotor performance testing device 21, thereby achieving the sorting of defective products. The function of the conveyor belt 42 is to provide a channel for defective product unloading, while the function of the partitions 43 is to divide the conveyor belt 42 into multiple independent tracks, each track corresponding to a specific performance parameter. This structure allows defective products to be accurately classified into the corresponding feeding tracks based on their performance defects, solving the problem of unclear defective product classification.
[0036] like Figure 1As shown in Figures 2 and 4, the good product unloading device 3 includes an unloading assembly 31 slidably mounted on the frame 1, and a clamping seat 32 mounted on the unloading assembly 31; the clamping seat 32 is used to clamp and position the rotor. The clamping seat 32 includes a base plate 321, a fixed block 322 mounted on the base plate 321, and a movable plate 323 movably mounted on the base plate 321 via an elastic support assembly 324; both ends of the rotor are positioned on the fixed block 322 and the movable plate 323, and the elastic support assembly 324 is used to press the movable plate 323 against the fixed block 322. Specifically, the elastic support assembly 324 can be made of springs, elastic rubber, or other elastic materials to ensure that the movable plate 323 can move flexibly within a certain range, while providing sufficient pressure to press the movable plate 323 against the fixed block 322. The base plate 321 can be connected to the unloading assembly 31 by bolts or other fixing methods to ensure the stability of the clamping seat 32. The surfaces of the fixed block 322 and the movable plate 323 can be provided with anti-slip textures or rubber pads to increase the friction with the rotor and prevent the rotor from sliding or shifting during clamping. In a preferred embodiment, the elastic support assembly 324 may include multiple springs evenly distributed between the movable plate 323 and the base plate 321 to ensure uniform force on the movable plate 323 and avoid inaccurate rotor positioning due to uneven force. Furthermore, the movable plate 323 can be connected to the base plate 321 via guide rails or grooves to ensure that the movable plate 323 can move in a predetermined direction under the action of the elastic support assembly 324, preventing the movable plate 323 from deflecting or tilting during movement. Therefore, the technical solution of this application solves the problem of inaccurate rotor clamping and positioning in the good product unloading device 3 through the sliding arrangement of the unloading pair 31 and the structural design of the clamping seat 32. The sliding arrangement of the unloading pair 31 allows the clamping seat 32 to move flexibly, facilitating rotor clamping and unloading. The fixed block 322 and the movable plate 323 in the clamping base 32 are connected by an elastic support assembly 324 to ensure stable positioning of the rotor in the clamping base 32. Both ends of the rotor are positioned on the fixed block 322 and the movable plate 323 respectively. The pressure of the elastic support assembly 324 ensures that the rotor will not shift or vibrate during clamping, improving the accuracy and stability of clamping. Compared with the prior art, the technical solution of this application has the following advantages: First, the design of the elastic support assembly 324 can adapt to different types of rotors. Even if the axial length of the rotor is different, it can be compatible through the elastic support assembly 324, improving the versatility of the equipment. Second, the elastic design of the movable plate 323 can effectively absorb the vibration that may be generated by the rotor during clamping, ensuring the stability of the rotor during the testing process and improving the accuracy of the testing. Finally, the clamping base 32 has a simple structure, is easy to manufacture and maintain, and reduces the manufacturing and operating costs of the equipment.
[0037] like Figures 5-9As shown, the rotor performance testing fixture 2 also includes a base 22, a support frame 23 for placing the rotor, and a steering clamping module 24 for clamping the rotor and adjusting its angle. The steering clamping module 24 includes a drive assembly, a gripper assembly 241 mounted on the drive assembly for clamping the rotor, and a first sensor 242 for detecting the rotor. The drive assembly drives the gripper assembly 241 and the rotor on it to rotate and adjust based on the sensor's detection information. At least one of the rotor performance testing device 21 and the steering clamping module 24 is movably mounted on the base 22 to allow the rotor to slide into or out of the testing chamber 210 from the opening 211. The rotor performance testing device 21 is used to perform performance testing on the rotor within the testing chamber 210. Specifically, in this design, the base 22 serves as the basic structure of the entire fixture, and the support frame 23 is used to stably place the rotor for initial positioning. The steering clamping module 24 achieves precise clamping and angle adjustment of the rotor through the drive assembly and the gripper assembly 241. The first sensor 242 is used to detect the rotor's position and angle in real time to ensure the accuracy of the detection. The movable arrangement of the rotor performance testing device 21 and the steering clamping module 24 allows the rotor to easily slide into or out of the testing chamber 210, improving testing efficiency. The synergy of these technical features effectively solves the positioning and adjustment problems in rotor performance testing, enhancing the accuracy and efficiency of the testing. Therefore, this application solves the problems of inaccurate rotor positioning and difficulty in angle adjustment by introducing the base 22, support frame 23, and steering clamping module 24. The support frame 23 is used to stably place the rotor, achieving initial positioning. The steering clamping module 24 achieves precise clamping and angle adjustment of the rotor through the drive assembly and the gripper assembly 241. The first sensor 242 is used to detect the rotor's position and angle in real time, ensuring testing accuracy. Furthermore, the movable arrangement of the rotor performance testing device 21 and the steering clamping module 24 allows the rotor to easily slide into or out of the testing chamber 210, improving testing efficiency. The synergy of these technical features effectively solves the positioning and adjustment problems in rotor performance testing, enhancing the accuracy and efficiency of the testing.
[0038] In a specific implementation, the upper end of the support frame 23 is provided with an arc-shaped groove 231 for positioning the rotor; a first sensor 242 is provided on the support frame 23 next to the arc-shaped groove 231, facing into the arc-shaped groove 231; a sensor bracket 232 is provided on the support frame 23, and a second sensor 233 is provided on the sensor bracket 232 for detecting whether the rotor is placed in the arc-shaped groove 231. The design of the arc-shaped groove 231 can effectively reduce the positional deviation of the rotor during the testing process. The first sensor 242 is used to detect the position of the rotor in the arc-shaped groove 231 to ensure that the rotor is in the correct testing position; the second sensor 233 is used to confirm whether the rotor has been correctly placed in the arc-shaped groove 231, avoiding testing errors caused by the rotor not being placed in the correct position. Through this design, this application effectively solves the problems of inaccurate rotor positioning and low testing efficiency during performance testing. Specifically, the shape and size of the arc-shaped groove 231 can be customized according to the specific shape and size of the rotor to ensure that the rotor can be stably placed in the groove. The first sensor 242, which can be a photoelectric sensor or a proximity sensor, is used to detect whether the rotor is located at a predetermined position in the arc-shaped groove 231. The second sensor 233, which can be a pressure sensor or a photoelectric sensor, is used to detect whether the rotor has been correctly placed in the arc-shaped groove 231. The design of the sensor bracket 232 should ensure that the position and angle of the sensor can accurately detect the position and state of the rotor. Thus, this application achieves preliminary positioning of the rotor through the arc-shaped groove 231 on the support frame 23. The design of the arc-shaped groove 231 can effectively reduce the positional deviation of the rotor during the detection process. The setting of the first sensor 242 and the second sensor 233 further improves the accuracy and efficiency of the detection. The first sensor 242 is used to detect the position of the rotor in the arc-shaped groove 231, ensuring that the rotor is in the correct detection position; the second sensor 233 is used to confirm whether the rotor has been correctly placed in the arc-shaped groove 231, avoiding detection errors caused by the rotor not being placed in the correct position. Through this design, this application effectively solves the problems of inaccurate rotor positioning and low detection efficiency during the performance testing process. Compared with the prior art, the technical solution of this application has the following advantages: First, the design of the arc groove 231 can effectively reduce the position deviation of the rotor during the detection process and improve the accuracy of the detection; Second, the setting of the first sensor 242 and the second sensor 233 further improves the accuracy and efficiency of the detection and avoids the detection error caused by the rotor not being placed in place; Finally, the technical solution of this application has a simple structure, is easy to implement, and can be widely used in various rotor performance testing equipment.
[0039] like Figure 5 and 6As shown, the steering clamping module 24 is mounted on the fixed frame 221 of the base 22, and the rotor performance testing device 21 is mounted on the sliding pair 222 of the base 22. The sliding pair 222 drives the rotor performance testing device 21 to move. The sliding pair 222 is mounted on the slide rail of the base 22, and the base 22 is also equipped with a drive cylinder for driving the sliding pair 222 to move along the slide rail. The steering clamping module 24 is fixed to the base 22 by the fixed frame 221, ensuring the stability of the clamping module and reducing vibration and angular errors. The rotor performance testing device 21 moves on the slide rail via the sliding pair 222, enabling the testing device to move precisely to the testing position, improving the accuracy and repeatability of the test. The drive cylinder controls the movement of the sliding pair 222, further ensuring the precise position adjustment of the testing device. These technical features work together to solve the problems of inaccurate positioning and angular errors in the rotor performance testing process, improving testing efficiency and accuracy. Specifically, the steering clamping module 24 includes a drive assembly and a gripper assembly 241. The drive assembly is connected to the base 22 via a fixing frame 221, and the gripper assembly 241 is used to clamp the rotor and adjust its angle. A sliding pair 222 is connected to the base 22 via a slide rail, the design of which allows the sliding pair 222 to move precisely in a straight line. A drive cylinder controls the movement of the sliding pair 222 via air pressure, ensuring that the testing device can quickly and accurately reach the designated position. Therefore, the technical solution of this application effectively solves the problems of inaccurate positioning and angle error during rotor performance testing through the synergistic effect of the steering clamping module 24 and the sliding pair 222. Compared with the prior art, this solution significantly improves the accuracy and repeatability of testing, reduces the need for manual intervention, and increases testing efficiency through the optimization of the mechanical structure and the improvement of the driving method.
[0040] like Figure 8 and 9As shown, a turntable 243 is mounted on the fixed frame 221. A drive assembly drives and connects to the turntable 243, and a gripper assembly 241 is mounted on the turntable 243. The drive assembly includes a drive motor 244 and a pulley assembly 245 or a reducer connected to the output shaft of the drive motor 244. The drive motor 244 is connected to the turntable 243 via the pulley assembly 245 or the reducer. The design of the turntable 243 allows the gripper assembly 241 to be separated from the drive assembly, thus avoiding vibration and errors that might occur from directly driving the gripper assembly 241. The drive motor 244 transmits power through the pulley assembly 245 or the reducer, effectively reducing the rotational speed and increasing the torque, thereby ensuring the stability and accuracy of the gripper assembly 241 when clamping the rotor. Specifically, the selection of the pulley assembly 245 or the reducer can be adjusted according to actual needs. For example, the pulley assembly 245 is suitable for applications requiring a larger transmission ratio, while the reducer is suitable for applications requiring precise speed control. In a preferred embodiment, the drive motor 244 can be a stepper motor or a servo motor to achieve more precise speed control. Therefore, this application separates the gripper assembly 241 from the drive assembly through the turntable 243 structure on the fixed frame 221, and connects the drive motor 244 to the turntable 243 via a pulley assembly 245 or a reducer. This design makes the drive of the gripper assembly 241 more precise and stable, avoiding vibration and errors that may result from directly driving the gripper assembly 241. The drive motor 244 transmits power through the pulley assembly 245 or the reducer, effectively reducing the speed and increasing the torque, thereby ensuring the stability and accuracy of the gripper assembly 241 when clamping the rotor. Furthermore, the turntable 243 allows the gripper assembly 241 to rotate and adjust on the fixed frame 221 under the drive of the drive motor 244, further improving the positioning accuracy and detection efficiency of the rotor during the testing process. Compared with the prior art, the technical solution of this application has significant advantages in improving the accuracy and stability of rotor performance testing.
[0041] In a specific implementation, the gripper assembly 241 is constructed as a pneumatic gripper. A pneumatic gripper is a clamping device driven by air pressure. Its working principle is to control the opening and closing of the gripper through a pneumatic system, thereby achieving precise clamping and positioning. A pneumatic gripper typically consists of a cylinder, a gripper arm, and a control system. The cylinder drives the opening and closing of the gripper arm through changes in air pressure, while the control system is used to adjust the air pressure and the movement speed of the gripper. Specifically, the implementation of a pneumatic gripper can include the following: First, the gripper arm can be made of high-strength materials to ensure its stability and durability during clamping; second, the cylinder can be a double-acting cylinder, achieving rapid opening and closing of the gripper through bidirectional air pressure control; furthermore, the control system can be equipped with pressure sensors and position sensors to monitor the clamping force and position of the gripper in real time, thereby ensuring clamping accuracy and stability. This application solves the problems of inaccurate positioning and complex operation of the gripper assembly 241 during rotor performance testing by constructing the gripper assembly 241 as a pneumatic gripper. Pneumatic grippers are characterized by their simple structure, convenient operation, and high positioning accuracy. They can effectively reduce angular errors and vibrations of the rotor during the testing process, thereby improving the accuracy and repeatability of performance testing. Compared with existing technologies, the use of pneumatic grippers not only simplifies the operation process and reduces manual intervention, but also improves testing efficiency, demonstrating significant practicality and innovation.
