Description

[0002] In existing technologies, the stator, as a core component of a motor, has a quality that directly impacts its performance and reliability. Therefore, rigorous electrical performance testing is crucial during stator production. Traditional stator testing and coding processes are often separate and inefficient: first, an operator manually places the stator on a test bench and connects it to test equipment for electrical performance testing. Next, the test results are manually recorded and the stator is transferred to a coding station. Finally, based on the recorded test results, the stator is coded manually through labeling, inkjet printing, or other methods. This approach is not only time-consuming and labor-intensive, but also prone to human error, affecting the accuracy of testing and coding, and increasing production costs.

[0003] To improve production efficiency and product quality, automated stator testing and coding equipment is emerging. For example, some existing equipment uses a robotic arm to automatically grasp and place stators and automatically code them after testing. However, these devices generally have limitations. For example, their positioning mechanisms are often designed for specific stators, lacking flexibility and making it difficult to adapt to the testing needs of stators of different models or sizes.

DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0027] like Figures 1 to 9 As shown, the stator detection qualified coding mechanism described in this embodiment includes a frame 100 and a laser coding terminal 200. The laser coding terminal 200 is used to laser code the stators that have passed the electrical performance test. The frame 100 is provided with a turntable 10 and a stator transfer mechanism 20. The turntable 10 is provided with a plurality of mounting slots 11 spaced evenly along its circumference. A positioning plate 30 is detachably installed in each of the mounting slots 11. A plate surface of each of the positioning plates 30 is provided with a space for accommodating the stators to be tested. The stator 300 has a positioning slot 40; a stator test seat 50 is arranged next to each positioning slot 40, and the top of the stator test seat 50 is provided with an electrical connection pin 60 that is plugged into and adapted to the stator lead head of the stator 300 to be tested; the frame 100 is also provided with a Z-axis screw lifting structure 70, and the laser end terminal 200 is fixedly mounted on the screw slider 71 of the Z-axis screw lifting structure 70, and the Z-axis screw lifting structure 70 is provided with a handwheel 72 for driving the screw slider 71 to rise and fall.

[0028] During specific implementation, the frame 100 is used as the supporting base, and the laser coding terminal 200 is responsible for laser coding and marking after the stator completes the electrical performance test. It is fixedly installed on the screw slider 71 of the Z-axis screw lifting structure 70, that is, by manually rotating the handwheel 72, the screw slider 71 can be driven to rise and fall along the Z-axis direction, and the height of the laser coding terminal 200 can be accurately adjusted to adapt to stators of different thicknesses or heights, ensuring the best coding effect.

[0029] When performing a stator test, the operator first selects a corresponding positioning plate 30 according to the specifications of the stator 300 to be tested and installs it on the turntable 10. Then, the stator 300 to be tested is placed in the positioning slot 40 on the positioning plate 30. At this time, the operator plugs the stator lead head (not shown) of the stator 300 to be tested into the electrical connection pin 60 at the top of the stator test socket 50 to establish a reliable electrical connection. This connection allows the stator test socket 50 to be connected to external electrical performance testing equipment (for example, a motor stator comprehensive tester) to perform a comprehensive electrical performance test on the stator, including AC withstand voltage, insulation resistance, inter-turn withstand voltage, DC resistance, inductance, reverse embedding and steering.

[0030] Once the stator 300 to be tested completes the test and passes the test, the turntable 10 rotates, precisely positioning the stator 300 next to the laser marking station 200. The laser marking station 200 then activates and laser codes the stator 300, marking key information such as production date, serial number, specifications, and model number. After the coding is completed, the stator rotates to the predetermined position with the turntable 10 and can be transported manually or robotically to the conveyor line for the next process or to the finished product storage area. For unqualified stators, the stator transfer mechanism 20 (e.g., a robotic arm equipped with a vacuum suction cup or clamping device) removes them from the positioning slot 40 and transfers them to the rejection area for rework.

[0031] It is worth emphasizing that the present invention utilizes a replaceable positioning plate 30. By replacing different positioning plates 30 according to the specifications of the stator to be measured, the mechanism can flexibly accommodate stators of various specifications, models, and sizes, eliminating the need for customized testing and coding equipment for each stator. This modular design greatly improves the versatility and utilization of the equipment, effectively reducing production costs and equipment investment. Furthermore, the positioning plate 30 can be replaced quickly and easily, further enhancing production efficiency. For example, the positioning plate 30 can be secured to the turntable 10 using a quick-locking mechanism, allowing for quick and convenient replacement.

[0032] In some embodiments, as Figure 5 As shown, a support block 41 is provided on the bottom side of the turntable 10 and / or the bottom side of the positioning plate 30. The support block 41 at least partially extends into the corresponding positioning slot 40 on the positioning plate 30. The support block 41 provides support for the stator 300 to be tested placed in the positioning slot 40 and also serves as a buffer layer to reduce direct contact and friction between the stator 300 to be tested and the positioning plate 30 or turntable 10, thereby preventing scratches or wear on the surface of the stator 300 to be tested. To enhance the durability and performance of the support block 41, the support block 41 can be made of a material with good wear resistance, shock resistance, and insulation properties, such as rubber or silicone.

[0033] In some embodiments, as Figure 5 As shown, the slot walls of the positioning slot 40 gradually widen toward the slot opening. With this structural design, since the slot opening is wider than the slot interior, the operator can more easily place the stator 300 to be tested into the positioning slot 40. Furthermore, the spacious slot opening reduces friction between the stator 300 to be tested and the slot walls, minimizing scratches or wear caused by friction, thereby effectively reducing the defect rate of the stator 300 to be tested due to damage during placement.

[0034] In some embodiments, as Figure 4 、 Figure 5As shown, a plurality of silicone blocks 42 are disposed around the notch of the positioning groove 40. The silicone blocks 42 at least partially extend into the positioning groove 40, and the portion of the silicone block 42 located within the positioning groove 40 is provided with an inclined surface 43, which is inclined toward the interior of the positioning groove 40. In this way, the elasticity and friction of the silicone blocks 42 can effectively secure the stator 300 to be tested, preventing it from moving or loosening during the testing and coding process. The design of the inclined surface 43 further enhances the securing effect, guiding the stator 300 to be tested to slide toward the bottom of the positioning groove 40, firmly fixing it in the appropriate position, and reducing the resistance of the stator 300 to be tested when placed into the positioning groove 40.

[0035] In some embodiments, as Figure 4 、 Figure 5 、 Figure 6 As shown, a terminal 51 for connecting an external electrical performance test device is embedded on the side of the stator test socket 50, and the electrical connection pin 60 is electrically connected to the terminal 51; a pad 52 is provided on the top of the stator test socket 50, and a guide sliding hole 53 is provided on the pad 52 to match the electrical connection pin 60, and a tension spring 54 is fixedly connected to the side of the pad 52 facing the stator test socket 50; a countersunk hole 55 for accommodating the tension spring 54 is provided on the top of the stator test socket 50, and the side of the tension spring 54 facing away from the pad 52 is fixed to the bottom of the countersunk hole 55; a push rod 56 is provided at the bottom of the pad 52, and the lower end of the push rod 56 extends to the bottom of the table of the turntable 10, and a lifting cylinder 57 coaxially arranged with the push rod 56 is provided below the table of the turntable 10.

[0036] During the test, the force of the tension spring 54 causes the pad 52 to press against the stator test socket 50, exposing the electrical connection pin 60. At this point, the operator can align the stator lead head with the electrical connection pin 60 on the pad 52 and insert it into the electrical connection pin 60, so that the electrical connection pin 60 is in close contact with the stator lead head, establishing a reliable electrical connection. Next, the stator is subjected to an electrical performance test through an external test device connected to the terminal 51. After the test is completed, the lifting cylinder 57 is extended until the pad 52 overcomes the preload of the tension spring 54 and separates from the stator test socket 50. At this point, the stator lead head is detached from the electrical connection pin 60. Finally, the control cylinder 57 is retracted, causing the push rod 56 and the pad 52 to reset under the action of the tension spring 54, ready for the next test. The entire process is completed automatically without manual intervention, which improves test efficiency and reliability and reduces human operation errors.

[0037] In some embodiments, as Figure 6 、 Figure 8 、 Figure 9As shown, the stator test socket 50 includes a first portion 50a and a second portion 50b stacked one above the other. A groove 50c is provided on the side of the second portion 50b facing the first portion 50a. The terminal 51 is embedded in the second portion 50b and at least partially placed in the groove 50c. The electrical connection pin 60 is fixed to the first portion 50a, and the electrical connection pin 60 is at least partially placed in the groove 50c.

[0038] With this structural design, first, the groove 50c provides an accommodation space for the wiring harness connecting the terminal 51 and the electrical connection pin 60, making the internal wiring more regular, avoiding exposure of the wiring harness, and protecting the wiring harness from external damage, thereby improving the reliability and safety of the connection; secondly, the modular design of dividing the stator test socket 50 into an independent first part 50a and a second part 50b greatly simplifies the maintenance and replacement process of the stator test socket 50, that is, whether the terminal 51 or the electrical connection pin 60 fails, or a different model of terminal 51 needs to be replaced to adapt to different test equipment, it is only necessary to replace the corresponding parts, without disassembling or replacing the entire stator test socket 50, which significantly reduces maintenance costs and time and improves the maintenance efficiency of the equipment.

[0039] In some embodiments, as Figure 8 As shown, an insulating sleeve 61 is provided on the electrical connection pin 60, and the top end of the electrical connection pin 60 is at least partially exposed outside the insulating sleeve 61; the aperture of the guide slide hole 53 is adapted to the diameter of the insulating sleeve 61. In this way, the insulating sleeve 61 can not only effectively isolate the electrical connection pin 70 from other conductive components, ensuring the safety of operators and equipment, but also protect the electrical connection pin 70 from damage such as wear, corrosion and oxidation, especially in the case of frequent plug-in and unplug testing, effectively extending its service life. In this embodiment, preferably, the insulating sleeve 61 is made of a brightly colored insulating material, such as red or yellow, so as to clearly mark the position of the electrical connection pin 70, facilitate the operator to quickly and accurately perform connection and disconnection operations, and improve the safety of the operation.

[0040] In some embodiments, as Figure 2As shown, the stator transfer mechanism 20 includes an X-axis moving mechanism 21, a Z-axis lifting mechanism 22 and a finger cylinder 23. The finger cylinder 23 is arranged at the power output end of the Z-axis lifting mechanism 22, and the Z-axis lifting mechanism 22 is arranged at the power output end of the X-axis moving mechanism 21. In this embodiment, the X-axis moving mechanism 21 is an electric linear slider guide or an electric screw nut guide, and the Z-axis lifting mechanism 22 is an electric screw lifting structure, an electric lifting structure or a cylinder lifting structure. In specific implementation, the X-axis moving mechanism 21 is responsible for horizontal movement, the Z-axis lifting mechanism 22 is responsible for vertical movement, and the finger cylinder 23 is responsible for grasping and releasing the stator. This can realize the movement of the stator to any position in the working area, and facilitate the transfer of the stator between different workstations, for example, from the test area on the turntable 20 to the output area.

[0041] The stator inspection and coding mechanism provided in this embodiment integrates stator testing and laser coding functions and adopts a replaceable positioning plate and an adjustable test socket, thereby achieving high flexibility and compatibility. It can adapt to stators of different specifications, models or sizes without the need for frequent replacement or adjustment of equipment. At the same time, the design of immediate coding after passing the test does not require intermediate transfer or manual intervention, greatly shortening the production cycle, improving production efficiency, effectively reducing equipment investment costs and the complexity of the production line, and improving the traceability of product quality.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.
