Technical Field

[0001] The present invention relates to the technical field of core slope detection, and specifically to a device and method for detecting the slope of a skewed rotor core. Background Art

[0002] With the rapid development of the new energy vehicle industry, the quality of the motor, which is the "heart" of the vehicle, is particularly important. As the core component of the motor, the quality and production efficiency of the core play a key role in core manufacturing. Among them, the cast aluminum rotor core occupies a relatively high share in the market, and its key quality characteristic, the skewed slope, directly affects the operating performance of the motor.

[0003] The current detection methods cannot achieve 100% full inspection, it is difficult to effectively detect whether there is waste clamped in the core slots, and it is also impossible to monitor the skewed abnormality in the middle section of the core. Once quality problems occur, it is easy to cause batch defects. At the same time, traditional detection methods are difficult to meet the requirements of fast production beats. Under the premise of ensuring product quality, there are problems such as low production efficiency and high labor intensity of employees.

[0004] Therefore, a device and method for detecting the slope of a skewed rotor core are proposed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a device and method for detecting the slope of a skewed rotor core, which have the advantages of 100% detection and calculation of the core slots and slope through a camera, effectively solving the problems that traditional detection methods cannot perform 100% detection, cannot detect waste clamping and skewed abnormalities in the middle section of the core, as well as low production efficiency and high labor intensity.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A device for detecting the slope of a skewed rotor core, including a chassis, a support mechanism is installed on the chassis, a driving mechanism is installed on the support mechanism, and a core to be detected is installed on the driving mechanism;

[0007] On both sides of the support mechanism, a first detection mechanism and a second detection mechanism are respectively installed. The first detection mechanism is used to detect the included angle of the aluminum slot side lines of the core to be detected, and the second detection mechanism is used to detect the cleanliness of the aluminum slots of the core to be detected.

[0008] Preferably, the support mechanism includes a support frame, reserved slots are respectively opened on both sides of the support frame, a limit frame is installed in the reserved slots, and the limit frame is used to guide the displacement of the first detection mechanism and the second detection mechanism in the horizontal direction;

[0009] A positioning frame is installed on the support frame, and a reserved hole for installing the driving mechanism is opened on the support frame inside the positioning frame.

[0010] When adopting the above technical solution, the cooperation between the limit frame and the reserved groove realizes the precise guiding of the horizontal displacement of the first detection mechanism and the second detection mechanism. The setting of the positioning frame and the reserved hole realizes the stable installation of the driving mechanism. The supporting mechanism has the functions of stably supporting each component of the detection device and guiding the displacement of the detection mechanism, ensuring the accuracy of the mechanism position during the detection process.

[0011] Preferably, the first detection mechanism includes a first slider. A first sliding groove is formed on the first slider. The first slider can be displaced in the horizontal direction through the cooperation of the first sliding groove and the limit frame.

[0012] A first camera is movably installed on the first slider. The first camera is used to detect the edge line of the aluminum groove at the bottom of the iron core to be detected.

[0013] A first vertical rod is fixedly installed on the first slider. A first mounting frame is installed on the first vertical rod. A second camera is movably installed on the first mounting frame. The second camera is used to detect the edge line of the aluminum groove at the top of the iron core to be detected.

[0014] When adopting the above technical solution, the first slider realizes the horizontal position adjustment of the first detection mechanism through the sliding cooperation of the first sliding groove and the limit frame. The movable mounting structures of the first camera and the second camera realize the synchronous image acquisition of the edge lines of the aluminum grooves at the upper and lower ends of the iron core. The first detection mechanism has the precise detection ability to calculate the skew angle based on the position data of the upper and lower end edge lines, ensuring the accuracy of the slope value calculation.

[0015] Preferably, the second detection mechanism includes a second slider. A second sliding groove is formed on the second slider. The second slider can be displaced in the horizontal direction through the cooperation of the second sliding groove and the limit frame.

[0016] A second vertical rod is fixedly installed on the second slider. A second mounting frame is installed on the second vertical rod. A third camera is provided on the second mounting frame. The third camera is used to detect the cleanliness of the aluminum groove of the iron core to be detected. A rotating shaft is installed on the third camera.

[0017] When adopting the above technical solution, the second slider realizes the horizontal position adjustment of the second detection mechanism through the cooperation of the second sliding groove and the limit frame. The third camera realizes the adaptation to the skew angle of the iron core through the angle adjustment of the rotating shaft. The second detection mechanism has the all-round image detection function for clamping waste materials, foreign objects and area in the aluminum groove, and can identify 100% of the aluminum groove defects.

[0018] Preferably, the chassis includes a bottom plate. Two vertical plates are installed on the bottom plate. A first adjusting cylinder and a second adjusting cylinder are respectively rotatably installed on the two vertical plates.

[0019] The piston ends of the first adjustment cylinder and the second adjustment cylinder facing away from the vertical plate are respectively connected to the first slider and the second slider. The first adjustment cylinder and the second adjustment cylinder are respectively used to push the first slider and the second slider to displace horizontally along the limit frame.

[0020] When the above technical solution is adopted, the piston expansion and contraction of the first adjustment cylinder and the second adjustment cylinder drive the first slider and the second slider to displace along the limit frame, realizing the automatic adjustment of the horizontal position of the detection mechanism. The chassis has the function of quickly adjusting the position of the detection camera according to the core diameter, improving the adaptation efficiency of the device to products of different specifications.

[0021] Preferably, the driving mechanism includes a driving motor. The driving motor is fixedly installed at the bottom of the support frame. The transmission end of the driving motor passes through the reserved hole on the support frame and is drivingly installed with a speed reducer. The transmission end at the top of the speed reducer is installed with a clamping frame. The clamping frame is used to clamp the core to be detected, and the outer wall of the clamping frame is in dynamic contact with the inner wall of the positioning frame.

[0022] When the above technical solution is adopted, the driving motor drives the clamping frame through the speed reducer to realize the 360° rotation of the core. The dynamic contact between the positioning frame and the clamping frame ensures the axial positioning accuracy of the core. The driving mechanism has the function of stably clamping the core and driving it to rotate at a constant speed, providing a motion basis for the full-circle detection of the aluminum groove and the calculation of the slope, and ensuring the continuity and accuracy of the detection process.

[0023] A method for detecting the slope of a skewed rotor core includes the following steps:

[0024] Step 1. Core installation and driving positioning: Fix the core to be detected on the clamping frame of the driving mechanism, and realize axial positioning through the dynamic contact between the inner wall of the positioning frame and the outer wall of the clamping frame to ensure that the axis of the core coincides with the transmission axis of the driving motor;

[0025] Step 2. Horizontal adjustment of the detection mechanism: Through the piston expansion and contraction of the first adjustment cylinder and the second adjustment cylinder on the chassis, push the first slider of the first detection mechanism and the second slider of the second detection mechanism to displace horizontally along the limit frame of the support mechanism, so that the first camera and the second camera are aligned with the upper and lower aluminum grooves of the core, and the third camera is aligned with the aluminum groove detection area;

[0026] Step 3. Camera angle adaptation adjustment: Adjust the shooting angle of the third camera through the rotating shaft of the second detection mechanism to match the skewed angle of the core; at the same time, through the movable installation structure of the first camera and the second camera in the first detection mechanism, ensure that the lens is perpendicular to the aluminum groove detection surface;

[0027] Step 4. Cleanliness and area detection of the aluminum groove: Start the drive motor, drive the iron core to rotate 360° horizontally through the reducer, use the third camera to collect the image of the aluminum groove, and detect the waste and foreign objects in the groove and the area of the aluminum groove; if the area is out of tolerance or there are foreign objects, the system determines it as unqualified and alarms.

[0028] Step 5. Calculation of the slope angle: When the aluminum groove is detected to be qualified, use the first camera to detect the same side line of the aluminum groove at the bottom of the iron core, and the second camera to detect the corresponding side line of the aluminum groove at the top. Calculate the included angle based on the position data of the two side lines to obtain the skew angle value.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] In the present invention, the first detection mechanism and the second detection mechanism are respectively arranged on both sides of the support mechanism. The first detection mechanism uses a camera to detect the included angle of the aluminum groove side line of the iron core to be detected, and the second detection mechanism uses a camera to detect the cleanliness of the aluminum groove. Cooperating with the drive mechanism to drive the iron core to be detected to rotate, it achieves a 100% automatic detection effect on the waste clamped in the core slot hole and the slope.

[0031] By setting the linkage structure of the chassis, the support mechanism and the drive mechanism in the present invention, the iron core to be detected can rotate 360° horizontally during the detection process. Cooperating with the synchronous detection of the two-side detection mechanisms, it achieves the effect of covering the entire circumference of the aluminum groove of the iron core, accurately identifying the clamped waste and the abnormal skew in the middle section, and solving the problem that the traditional detection method cannot fully detect and locate the defects in the middle section.

[0065] Embodiment 4

[0066] A method for detecting the slope of a skewed rotor iron core includes the following steps:

Based on the position data of the two side lines, the included angle is calculated to obtain the skew angle value.
