Description

Technical Field

[0001] This utility model relates to the field of stator lamination coating technology, specifically to an online detection device for stator lamination coating defects. Background Technology

[0002] Stator blades, also known as stator laminations, are made by stamping amorphous composite sheets into laminations of different specifications to suit the stators of electric motors with different power ratings. In addition, amorphous composite sheets are increasingly used as the core blade material for new energy vehicles. Amorphous composite sheets are thin composite amorphous sheets with very low carbon content. In order to obtain feasible low hysteresis loss, they are produced under special control conditions. Generally, pure iron is not suitable for alternating magnetic fields, mainly because its resistivity is low, which will cause large eddy current losses. After adding silicon, the resistivity is increased because silicon and iron form a solid solution alloy.

[0003] For example, patent document CN 215676751 U discloses a motor stator lamination testing device, which relates to the field of motor technology. A side limiting block is movably provided at the side opening of the outer fixing frame, and a base plate is fixedly connected to the bottom of the outer fixing frame; an installation groove is provided on the inner side of the outer fixing frame, and the outer edge of the first testing module corresponds to the installation groove; an installation hole is provided on the top of the outer fixing frame, and the first testing module is inserted along the installation groove and fixed to the outer fixing frame with bolts; both ends of the side limiting block are inserted along the installation groove and fixed to the outer fixing frame with bolts, and a second testing module is installed in the inner connecting groove of the side limiting block; the space enclosed by the first and second testing modules corresponds to the outer edge structure of the stator lamination unit. The advantages of this utility model are: it can test stator laminations of different specifications, reducing production costs; the installation structure of the first and second testing modules is robust and easy to install and test.

[0004] However, in actual use, due to its structural limitations, this structure often only performs simple single-sided detection of stator lamination adhesive defects, resulting in low detection efficiency. Furthermore, the equipment cannot be adjusted to better suit the angle of stator lamination adhesive defect detection, which fails to improve the overall detection accuracy and meet daily usage needs. Therefore, there is an urgent need to design an online detection device for stator lamination adhesive defects to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an online detection device for stator lamination adhesive defects, in order to solve the problems mentioned in the background art. In actual use, due to the limitations of its own structure, the existing structure often only performs simple single-sided detection of stator lamination adhesive defects, resulting in low detection efficiency. At the same time, the equipment cannot perform more suitable angle adjustments for stator lamination adhesive defect detection, which cannot improve the overall detection accuracy of the equipment and cannot meet the needs of daily use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an online detection device for stator lamination coating defects, comprising a detection frame, wherein a reinforcing outer frame is fixedly connected to both the upper and lower ends of the detection frame, a detection component is provided inside the reinforcing outer frame, and a limit component is provided inside the detection frame; The detection component includes an adjustment frame, the inner wall of the reinforced outer frame is fixedly connected to the adjustment frame, and a detector is installed inside the adjustment frame; The limiting component feeding drawer is internally and movably connected to the detection frame.

[0007] Preferably, the inside of the feeding drawer is provided with a detection groove, and the inner wall of the detection groove is provided with limit frame airbags on the upper and lower sides.

[0008] Preferably, the inner wall of the limiting frame airbag is provided with positioning inner seats on the upper and lower sides, and an adhesive pad is provided between the upper and lower positioning inner seats.

[0009] Preferably, the detector has a ring light at its bottom edge and a detection probe at its bottom center.

[0010] Preferably, hydraulic push rods are provided at the four internal corners of the adjusting frame, and universal joints are provided at the bottom ends of the hydraulic push rods.

[0011] Preferably, the adjustment frame has an internal mounting groove.

[0012] Preferably, the inner wall of the testing frame is fixedly connected to a limiting inner frame, which is adapted to the feeding drawer.

[0013] Preferably, the detection frame and the feeding drawer are compatible.

[0014] Preferably, the upper and lower adjustment frames and the detector are compatible.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This online detection device for stator lamination adhesive defects, through its detection frame, reinforced outer frame, detector, feeding tray, ring lights and detection probes, mounting slots, and limiting inner frame, enables more efficient online detection of stator lamination adhesive defects. In actual use, the operator first places the feeding tray, which is adapted to the specified size of stator laminations, into the detection frame. At this time, the limiting inner frame on the inner wall of the detection frame can perform a matching positioning and docking operation with the feeding tray. Then, the stator laminations that need to be detected for online adhesive defects are placed one by one into the center of the feeding tray. Simultaneously, the detector inside the upper and lower reinforced outer frames of the detection frame can be activated, controlling the upper and lower sets of ring lights and detection probes to start synchronously. The detection probes illuminate the upper and lower surfaces of the detection frame and then perform synchronous online detection of adhesive defects on the upper and lower surfaces of the stator laminations, greatly improving the inspection efficiency of the equipment and demonstrating the practicality of the equipment design.

[0016] This online detection device for stator lamination adhesive defects, through its detection frame, adjustment frame, detector, feeding tray, detection slot, limit frame airbag, positioning inner seat, bonding pad, hydraulic push rod, and universal joint, further improves the overall usability of the equipment. In daily use, operators can quickly assemble the detector through the mounting slot on the inner wall of the adjustment frame. When the detector is in use, the hydraulic push rods at the four corners of the upper and lower adjustment frame can be activated simultaneously, causing the universal joint at one end to adjust the angle of the stator laminations within the feeding tray. Simultaneously, when the stator laminations are adjusted within the feeding tray, the upper and lower limit frame airbags, in conjunction with the positioning inner seat and bonding pad, perform limiting and springback reset operations during stator lamination angle adjustment, demonstrating the comprehensiveness of the equipment design.

[0022] Working principle: During use, the operator first places the entire loading tray 5, which is adapted to the specified size of the stator laminations, into the inspection frame 1. At this time, the inner limiting frame 15 on the inner wall of the inspection frame 1 can perform a matching positioning and docking operation with the loading tray 5.

The equipment boasts high inspection efficiency. During daily use, the inspector 4 can be quickly assembled and installed by the staff through the mounting groove 14 on the inner wall of the adjusting frame 3.
