Description

Technical Field

[0001] The present invention is applied to the technical field of inductive magnetic winding wires, and particularly relates to a hot-cut component, a winding machine, and a working method. Background Art

[0002] An inductor typically includes at least one magnetic ring, which requires enameled wire to be wound around it. Currently, automated mechanical equipment is commonly used to wind the enameled wire around the ring. Different sizes of magnetic rings require different lengths for the enameled wire, so the wire must be cut after each winding. However, varying electrical performance requirements necessitate different lengths for the different enameled wire ends on the ring, making it impossible to simply use a cutter to uniformly cut the wire ends. Furthermore, due to the small diameter of the enameled wire, it is difficult to achieve precise positioning of the individual enameled wires after winding. Traditional enameled wire cutting involves pre-cutting the wire before winding. After winding, the wire is broken using a breaking device, allowing the wire ends to be cut to different lengths. The typical pre-cutting mechanism is a common shearing mechanism, which creates a scratch in the wire to enable subsequent breakage at a specific point. However, common shearing mechanisms can cause problems such as shallow cuts, missed cuts, and even direct wire severing. This requires frequent debugging, resulting in low product yields. For example, the Chinese patent with publication number 104795231B discloses a fully automatic network transformer winding machine, which includes an enameled wire pre-breaking mechanism, a T1 winding wire pre-twisting mechanism, a T1 winding wire mechanism, a tail wire breaking mechanism, a wire branching mechanism, a T2 winding wire pre-twisting mechanism and a T2 winding wire mechanism connected in sequence. The pre-breaking mechanism pre-breaks a part of the enameled wire in the diameter direction, or changes the shape and size of the cross-sectional area of ​​the enameled wire to achieve the purpose of pre-breaking. The effect is not ideal. In actual use, the subsequent pulling-off action is prone to failure to break, affecting the normal use of the equipment. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a hot-cut component, a winding machine and a working method with good pre-cutting effect and high working efficiency.

[0004] The technical solution adopted by the present invention is: the hot cutting assembly includes a fixing frame and several wire breaking seats, the fixing frame is provided with several guide shafts, the several wire breaking seats are slidably fitted on the several guide shafts in a one-to-one correspondence, a pair of porcelain eyes are provided on the wire breaking seat, a fuse is provided between the two porcelain eyes, the fuse is provided perpendicular to the connecting line of the two porcelain eyes, and the fuse is electrically connected to the external electronic control equipment.

[0005] As can be seen from the above scheme, the fuse is instantaneously energized by an external electric control device, thereby causing the fuse to be in a high position, burning the surface of the enameled wire in contact with it, and realizing pre-cutting. The enameled wire is kept in contact with the fuse by a pair of limiting porcelain eyes, thereby avoiding the situation of not being cut. At the same time, since the pre-cutting is performed by instantaneous power heating, the depth of each burn is basically the same, and it is guaranteed that there will be no direct cutting, thereby greatly improving the yield of the product, ensuring the normal winding of the magnetic ring, and avoiding the dragging of the magnetic ring after winding to affect subsequent processing. The design of the wire breaking seat slidingly fitting on the guide shaft can realize the adjustment of the pre-cutting position of different enameled wires, so that the lengths of different enameled wires can be customized according to needs, which is convenient for subsequent wire splitting.

[0006] A preferred solution is that the wire breaking seat cooperates with the guide shaft through a locking structure, the locking structure includes a fixing bolt, and the wire breaking seat is provided with a threaded hole adapted to the fixing bolt, and the fixing bolt passes through the threaded hole to cooperate with the guide shaft.

[0007] As can be seen from the above solution, the fixing of the wire cutting seat is achieved by providing the locking structure, ensuring that the wire cutting seat will not deviate when the device is working, thereby improving the accuracy of the pre-cutting point.

[0008] A preferred solution is that two wire breaking seats are provided on the conductor shaft at the same time, and all the porcelain eyes on the two wire breaking seats are located on the same axis.

[0009] It can be seen from the above solution that by simultaneously providing two wire breaking seats, the stability of the enameled wire operation can be improved, and the pre-cutting position can be switched as needed.

[0010] A preferred solution is that the disconnect seat is further provided with two fixing screws, and the two ends of the fuse are respectively fixed on the two fixing screws.

[0011] It can be seen from the above solution that the fuse is fixed by the two fixing screws.

[0012] The winding machine includes an enameled wire feeding mechanism, the hot cutting component, a T1 winding mechanism, a tail wire breaking mechanism, a wire dividing mechanism and a T2 winding mechanism connected in sequence. The enameled wire comes out of the enameled wire feeding mechanism and passes through the hot cutting component, and is pre-cut by the hot cutting component. The T1 winding mechanism is used to wind the pre-cut enameled wire around the T1 magnetic ring. The tail wire breaking mechanism is used to pull the enameled wire to break it from the pre-cut position. The wire dividing mechanism separates the wire end on the T1 magnetic ring that needs to be wound around the T2 magnetic ring. The T2 winding mechanism is used to wind the T2 magnetic ring around the separated wire end.

[0013] As can be seen from the above solution, by providing the hot cutting assembly between the enameled wire feeding mechanism and the T1 winding mechanism, a high-temperature scalding method is used to achieve effective and reliable pre-cutting, ensuring that the wire is not broken during winding. At the same time, the tail wire cutting mechanism is able to effectively cut the wire, ensuring that the products output to the wire branching mechanism and the T2 winding mechanism are qualified.

[0014] The working method of the winding machine comprises the following steps:

[0015] A. When the enameled wire output by the enameled wire feeding mechanism passes through the pair of porcelain eyes on the wire breaking seat, the enameled wire contacts the fusible wire;

[0016] B. After the enameled wire has been output to a specified length, the external electronic control device energizes the fuse, thereby burning the portion of the enameled wire in contact with the fuse, completing the pre-cutting;

[0017] C. The T1 winding mechanism winds the pre-cut enameled wire onto the T1 magnetic ring;

[0018] D. The wire-cutting mechanism simultaneously clamps the T1 magnetic ring and the enameled wire behind the pre-cutting point, and disconnects the enameled wire from the pre-cutting point through a stretching action;

[0019] E. The wire splitting mechanism separates the wire ends on the T1 magnetic ring that need to be wound around the T2 magnetic ring according to their lengths;

[0020] F. The T2 wire wrapping mechanism wraps the separated wire ends around the T2 magnetic ring. BRIEF DESCRIPTION OF THE DRAWINGS
