Description

Technical Field

[0001] This utility model relates to the field of leakage coil manufacturing technology, specifically to a leakage coil assembly and connection mechanism. Background Technology

[0002] A leakage current coil is a widely used device for detecting leakage current in circuits. Based on the principle of a current transformer, the current in the circuit is in a balanced state during normal operation. At this time, the vector sum of the currents in the leakage current coil is zero, and no induced voltage is generated. However, when leakage current or electric shock occurs in the circuit, an additional current flows through the leakage current coil, causing magnetic flux to be induced in the iron core. This, in turn, generates an output voltage in the secondary winding, triggering the trip unit to trip the automatic switch, thereby achieving the purpose of protection.

[0003] The magnetic yoke can constrain the outward diffusion of leakage magnetic flux from the induction coil, which not only improves the efficiency of induction heating, but also acts as a magnetic shield to reduce the heating phenomenon of metal components and strengthen the inductor. Therefore, in the production process of leakage coil, a semi-enclosed iron sheet needs to be inserted on the outside of the leakage coil for magnetic coating.

[0004] Currently, the process of adding a magnetic yoke is usually done manually, which is not only slow but also makes it impossible to check whether the installation is qualified after installation, resulting in some unqualified products among the leakage coils produced in batches.

[0005] To address the aforementioned issues, we propose an improvement: a leakage coil assembly and connection mechanism. Utility Model Content

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figure 1-7 As shown, a leakage current coil assembly and connection mechanism includes a mounting frame 1 and a stabilizing frame 10. A turntable 5 is mounted on the upper part of the mounting frame 1. Several columns 15 and positioning columns 17 are connected to the turntable 5. A camera 7 is connected to the top of the mounting frame 1. A connecting rail 9 is mounted on the top of the stabilizing frame 10. A clamping member 20 and a feeding tray 24 are provided at the end of the connecting rail 9. A feeding assembly 8 is connected to the other end of the connecting rail 9.

[0026] Four uprights 15 are evenly installed on the upper surface of the turntable 5. Limiting components 16 are fixedly installed on the upper surface of the uprights 15. Positioning posts 17 are fixedly installed on the upper surface of the limiting components 16. A leakage coil body 21 and a magnetic yoke 22 are sleeved on the positioning posts 17. Positioning holes 23 are provided on the leakage coil body 21 and the magnetic yoke 22. The inner diameter of the positioning holes 23 is consistent with the outer diameter of the positioning posts 17. The clamping workpiece in the previous step fixes the leakage coil body 21 and the magnetic yoke 22 inserted outside it from bottom to top, which facilitates subsequent riveting and fixation, and avoids displacement of the leakage coil body 21 and the magnetic yoke 22 during the riveting process.

[0027] A base frame 2 is fixedly installed on the upper surface of the mounting frame 1. A rotary motor is installed inside the base frame 2. The turntable 5 is rotatably connected to the upper surface of the base frame 2. The rotating shaft of the rotary motor is coaxially fixedly connected to the turntable 5. A connecting plate 3 is installed on the side of the mounting frame 1. A riveting machine 4 is fixedly installed on the inner surface of the connecting plate 3.

[0028] The riveting head of the riveting machine 4 corresponds to one of the positioning posts 17. The top frame 6 is fixedly installed on the outer top surface of the mounting frame 1. The camera 7 is fixedly connected to the top frame 6. The camera 7 penetrates downward through the top of the mounting frame 1 and is located directly above one of the positioning posts 17. The camera 7 is a Hikvision inspection camera.

[0029] The rotary motor drives the turntable 5 to rotate, and the turntable 5 rotates at a fixed angle each time, moving the leakage coil body 21 and the magnetic yoke 22 together to the bottom of the riveting machine 4. The riveting machine 4 uses the stationary iron core 14 to stably rivet the leakage coil body 21 and the magnetic yoke 22. Then the turntable 5 rotates again to the bottom of the camera 7. The camera 7 uses a visual algorithm to identify whether the riveting is qualified. If it is qualified, the clamp of the next process will clamp the leakage coil body 21 out. If it is not qualified, the leakage coil body 21 will be rotated back to the riveting machine 4 for re-riveting. When this step is repeated, the process of placing the stationary iron core 14 and fitting the leakage coil body 21 is paused.

[0030] An extension frame 11 is fixedly installed on the top of the stabilizer 10. A first drive member 12 is fixedly installed on the upper surface of the extension frame 11. Several push rods 13 are slidably installed inside the first drive member 12. A docking member 18 is fixedly connected to the other end of the push rod 13 away from the first drive member 12. Several electric telescopic rods are fixedly installed on the top of the docking member 18. A second drive member 19 is fixedly installed on the top of the electric telescopic rods. A pair of clamping members 20 are installed on the lower part of the second drive member 19, and the two clamping members 20 are installed opposite each other.

[0031] The feeding assembly 8 contains several stationary iron cores 14. The feeding tray 24 is fixedly installed at the end of the connecting rail 9 away from the feeding assembly 8, and a reserved slot 25 is opened inside the feeding tray 24. The stationary iron cores 14 enter the end of the reserved slot 25 along the connecting rail 9.

[0032] After the clamping member 20 clamps the innermost stationary iron core 14 of the reserved slot 25 under the drive of the second drive member 19, the first drive member 12 pushes the push rod 13 outward. After the clamping member 20 is directly above the positioning post 17, the electric telescopic rod shortens so that the clamping member 20 places the stationary iron core 14 on the top of the positioning post 17. The turntable 5 rotates so that the positioning post 17 moves to the outermost side, waiting for the workpiece to be clamped and the leakage coil body 21 to be put on.

[0033] The diameter of the positioning post 17 is the same as the bottom diameter of the stationary iron core 14, and the inner width of the connecting rail 9 and the reserved groove 25 are the same as the outer diameter of the stationary iron core 14.

[0034] Working principle: In this type of leakage coil assembly and connection mechanism, when in use, the clamping member 20, driven by the second driving member 19, clamps the innermost stationary iron core 14 of the reserved slot 25. Then, the first driving member 12 pushes the push rod 13 outward until the clamping member 20 is directly above the positioning post 17. The electric telescopic rod then shortens, allowing the clamping member 20 to place the stationary iron core 14 on top of the positioning post 17. The turntable 5 rotates, moving the positioning post 17 to its outermost position. The clamping workpiece from the previous step then passes through and fixes the leakage coil body 21 and the magnetic yoke 22 inserted outside it from bottom to top, facilitating subsequent riveting and preventing the leakage coil body 21 from being riveted during the riveting process. When the magnetic yoke 22 shifts, the rotary motor drives the turntable 5 to rotate, and the turntable 5 rotates at a fixed angle each time, moving the leakage coil body 21 and the magnetic yoke 22 together to the bottom of the riveting machine 4. The riveting machine 4 uses the stationary iron core 14 to stably rivet the leakage coil body 21 and the magnetic yoke 22. Then, the turntable 5 rotates again to the bottom of the camera 7, and the camera 7 uses a visual algorithm to identify whether the riveting is qualified. If it is qualified, the clamp of the next process will clamp the leakage coil body 21 out. If it is not qualified, the leakage coil body 21 will be rotated back to the riveting machine 4 for re-riveting. When this step is repeated, the process of placing the stationary iron core 14 and fitting the leakage coil body 21 is paused.

[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
