Description

Technical Field

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

[0002] A residual current circuit breaker (RCCB), also known as a residual current device (RCD), is manufactured by wrapping enameled wire and leads with insulating tape around a frame. When a leakage current exists in the main circuit, the RCD generates an induced electromotive force, detects the leakage current in the circuit, and causes the moving iron core inside the coil frame to actuate, thereby tripping the RCD and cutting off the power supply in time to prevent electric shock accidents.

[0003] Currently, the application of insulating tape to leakage current coils is mostly done manually by workers. This is not only inefficient, but also often results in the tape not adhering completely to the coil surface. The tape ends are also prone to curling and peeling, causing it to fall off during transportation and use.

[0004] To address the aforementioned issues, we have made improvements by proposing a leakage current coil tape winding mechanism. Utility Model Content

The lower part of the upper connector is connected to a back plate, and the front side of the back plate is connected to a mounting component and a pressure block. The bottom of the mounting component is connected to a roller and a cutting blade. The leakage current coil body is located on the front side of the back plate. The upper connector is externally connected to a device body, and a plurality of driving components are mounted on the device body. The driving components are connected to a linkage rod and a pressure rod.

[0008] As a preferred embodiment of this utility model, a reserved hole is provided at the bottom of the placement groove, and a docking groove is provided on the rear side of the cutting blade. The reserved hole and the docking groove are positioned correspondingly, and the top of the mounting component is in contact with the inner top surface of the reserved groove.

[0009] As a preferred embodiment of this utility model, the linkage rod is connected to an external drive assembly, and a plurality of docking holes are evenly provided on the surface of the linkage rod, with a plurality of pressure rods respectively inserted into the interior of the docking holes.

[0010] As a preferred embodiment of this utility model, the back plate includes a vertical plate and a bottom plate. The bottom plate is fixedly installed at the bottom of the vertical plate. Lower connecting parts are fixedly installed at both ends of the front side of the bottom plate. The roller is rotatably installed between the two lower connecting parts. The roller is made of rubber.

[0011] As a preferred embodiment of this utility model, a locking hole is provided on the side surface of the leakage coil body, the drive component on the device body is engaged with the locking hole, and the lengths of the roller and the cutting blade correspond to the internal length of the leakage coil body.

[0012] As a preferred technical solution of this utility model, a connecting plate is fixedly installed on the rear side of the upper connector, the rear side of the connecting plate is fixedly connected to the front surface of the back plate, and a plurality of connecting holes are opened on the upper part of the back plate, and the plurality of connecting holes extend inward to the interior of the upper connector.

[0013] The beneficial effects of this utility model are:

[0014] 1. This type of leakage coil tape winding mechanism is fully automated, improving overall processing efficiency and quality. The tape starting point is pressed onto the surface of the insulating coil by the pressure block. The rubber rollers are always in close contact with the surface of the leakage coil body during the process of the leakage coil body rotating and pasting the tape, reducing air bubbles and gaps between the tape and the leakage coil body.

[0015] 2. After the tape is pasted, use the pressure bar to press the insulating tape to the cutting blade for cutting, which improves the flatness of the cut surface of the tape.

[0022] 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.

[0023] Example: Figure 1-4 As shown, a leakage current coil tape winding mechanism includes an upper connector 1 and a leakage current coil body 13. The lower part of the upper connector 1 is connected to a back plate 5. The front side of the back plate 5 is connected to a mounting component 8 and a pressure block 9. The bottom of the mounting component 8 is connected to a roller 12 and a cutting blade 14. The leakage current coil body 13 is located on the front side of the back plate 5. The upper connector 1 is connected to a device body. Several drive components are installed on the device body. The drive components are connected to a linkage rod 2 and a pressure rod 4.

[0024] The lower part of the upper connector 1 has a reserved groove 7. The top of the mounting part 8 is hinged to the inside of the reserved groove 7. The front side of the mounting part 8 has a placement groove 10. The pressure block 9 is pasted inside the placement groove 10. The pressure block 9 is made of soft material, such as cotton and sponge. The softer material can increase the contact area between the pressure block 9 and the surface of the leakage coil body 13 during the pressing of the tape, so that the tape is pasted more firmly.

[0025] A pre-drilled hole 16 is provided at the bottom of the placement groove 10, and a mating groove 17 is provided on the rear side of the cutting blade 14. The positions of the pre-drilled hole 16 and the mating groove 17 are corresponding. The top of the mounting part 8 is fitted with the inner top surface of the pre-drilled groove 7. The cutting blade 14 can be stably connected to the mounting part 8 by bolts. However, after long-term use, adhesive residue is likely to remain on the surface of the cutting blade 14, resulting in poor cutting effect. The cutting blade 14 can be replaced by removing the bolts to ensure the cutting effect on the tape.

[0026] Linkage rod 2 is connected to an external drive assembly. Several docking holes 3 are evenly opened on the surface of linkage rod 2. Several pressure rods 4 are inserted into the docking holes 3 respectively. After the tape is wrapped, the drive assembly drives linkage rod 2 to move, so that the pressure rods 4 are close to the front side of the mounting part 8, and the tape is brought closer to the cutting blade 14, so that the cutting blade 14 cuts the tape.

[0027] The back plate 5 includes a vertical plate 501 and a bottom plate 502. The bottom plate 502 is fixedly installed at the bottom of the vertical plate 501. Lower connectors 11 are fixedly installed at both ends of the front side of the bottom plate 502. Rollers 12 are rotatably installed between the two lower connectors 11. The rollers 12 are made of rubber. The rubber material is relatively soft. During the process of rotating and wrapping the tape around the leakage coil body 13, the rollers 12 are always in close contact with the surface of the leakage coil body 13, pressing the tape flat and firmly onto the surface of the leakage coil body 13, reducing air bubbles during the wrapping process.

[0028] The side surface of the leakage coil body 13 is provided with a locking hole 18. The drive component on the main body of the device is engaged with the locking hole 18. The lengths of the roller 12 and the cutting blade 14 are both corresponding to the internal length of the leakage coil body 13. The leakage coil body 13 rotates with the drive component, pulling the tape while winding, which not only avoids the tape sticking in the middle, but also improves the efficiency of tape winding.

[0029] A connecting plate 6 is fixedly installed on the rear side of the upper connector 1. The rear side of the connecting plate 6 is fixedly connected to the front surface of the back plate 5. Several connecting holes 15 are opened on the upper part of the back plate 5, and the several connecting holes 15 extend inward to the interior of the upper connector 1.

[0030] Working principle: In use, several leakage coil bodies 13 that need to be wrapped with tape are connected to the drive component of the device body through the card holes 18 and approach the end of the tape. The pressure block 9 moves forward to press the end of the tape onto the surface of the leakage coil body 13. The drive component drives the leakage coil body 13 to rotate. At the same time, the upper connecting piece 1 drives the entire mechanism to move so that the roller 12 contacts the leakage coil body 13 and rotates synchronously with the rotation of the leakage coil body 13, thereby increasing the density of the tape wrapping of the leakage coil body 13. After the tape is wrapped, the drive component drives the linkage rod 2 to move, so that the pressure rod 4 approaches the front side of the mounting piece 8 and moves the tape toward the cutting blade 14, so that the cutting blade 14 cuts the tape.

[0031] 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.
