Description

TECHNICAL FIELD

[0002] The transformer is a device for changing AC voltage by using the principle of electromagnetic induction. In the process of processing the transformer, copper foil winding is needed. For dry-type transformers, planar transformers and other transformers, low-voltage foil winding processing is often needed. The planar form of copper foil is used for winding, which helps to improve the power transmission capacity and reduce the loss.

[0003] In the process of copper foil winding, insulating materials such as insulating tape and insulating film are often added to isolate the electrical connection between different winding layers and between the winding and the magnetic core. The copper foil and the insulating material need to have a certain degree of neatness. In the process of copper foil winding, the phenomenon of winding deviation of the foil tape and the insulating layer also needs to be avoided. The existing equipment adjusts the winding angle of the foil tape and the surface of the transformer in advance, and cannot be flexibly adjusted during the winding process. In addition, during the winding process, rollers are often added to press the surface to avoid gaps and wrinkles after the foil tape is wound. Such structure is difficult to adjust to other positions. The copper foil tape is generally thin. During the winding process, the worker will repeatedly rotate to adjust and knock the surface and the side to eliminate local winding problems, which increases the burden of the workers and reduces the work efficiency.

[0039] A winding adjusting mechanism matched with the fixed frame 2 is arranged above the winding roller 3, and the winding adjusting mechanism is used for adjusting the winding angle of the copper foil wound on the winding roller 3 through rotation.

[0040] A winding expansion mechanism matched with the fixed frame 2 is arranged below the winding roller 3, and the winding expansion mechanism is used for extruding the copper foil during winding to ensure the flatness and consistency of the copper foil winding, and is also used for flattening the two end faces of the transformer and slightly adjusting and correcting the copper foil which has deviated from the wound copper foil.

[0041] The winding adjusting mechanism and the winding expansion mechanism are distributed on the circumferential line of the winding roller 3 with the winding shaft 4 as the center, and through the circumferential distribution, the winding adjusting mechanism and the winding expansion mechanism can be tangent to the transformer during winding, so as to adjust and control the surface flatness and overall tightness of the winding.

[0042] Referring to Figures 1-6 In the specific embodiments of the present application, the winding adjusting mechanism comprises an adjusting shaft 5, and a plurality of adjusting sleeves 6 are arranged on the adjusting shaft 5, and the contact length with the surface of the copper foil can be controlled by adjusting the position and number of the adjusting sleeves 6, so as to realize local adjustment (such as applying stretching force to the general width area of the copper foil);

[0043] The adjusting sleeve 6 is provided with three adjusting arc plates 7, which form a circular ring structure, and the adjusting arc plates 7 are connected with the adjusting sleeve 6 through adjusting rods. The adjusting arc plates 7 can adjust the length to control the diameter of the circular ring structure, and the cooperation gap between the winding adjusting mechanism and the winding shaft 4 is directly adjusted. If the transformer surface is fitted, the winding process is tightened and tensioned to avoid the occurrence of wrinkles and non-fitting of the winding foil. If a gap is generated between the transformer surface, the rotation angle of the winding adjusting mechanism can be adjusted, and the entering angle of the copper foil during winding can be adjusted at the same time, so as to ensure the stability and surface neatness of the winding foil and ensure the winding tension. In addition, the winding adjusting mechanism can be installed between the copper foil and the transformer as a tensioning structure and adjust the connection position of the copper foil and the transformer during specific implementation.

[0044] The connecting plate 8 is provided with connecting grooves 9 at both ends of the connecting plate 8, which are matched with the adjusting shaft 5 and the winding shaft 4. The transmission belt is arranged between the two connecting grooves 9, and the transmission belt is matched with the adjusting shaft 5 and the winding shaft 4. After the transmission belt is installed, the adjusting shaft 5 and the winding shaft 4 will rotate synchronously, so that the winding quality can be ensured by rotating and pressing the surface of the transformer during winding.

[0045] Referring to Figures 1-6 In a preferred embodiment, a telescopic structure is arranged at the middle position of the connecting plate 8, which splits the plate body of the connecting plate 8. The telescopic structure makes the plate body of the connecting plate 8 away from the one end of the fixing frame 2 to stretch / contract. The telescopic structure includes a spring rod matched with the plate body of the connecting plate 8, or a hydraulic telescopic structure installed on the body of the connecting plate 8 and controlled by electricity, so that the connecting plate 8 has the telescopic function and is tangent to the surface of the transformer with a non-complete circular structure during winding.

[0046] Referring to Figures 1-6 In a preferred embodiment, a transmission wheel is arranged between the two connecting grooves 9 of the connecting plate 8, and the transmission wheel is connected with the adjusting shaft 5 and the winding shaft 4 through two transmission belts respectively, so as to change the rotation direction between the adjusting shaft 5 and the winding shaft 4.

[0049] When the lock bracket 11 is inserted into the fixing frame 2 and the connecting plate 8 at the same time, the angle of the fixing connecting plate 8 installed on the fixing frame 2 is adjusted, and the winding shaft 4 can normally rotate and operate;

[0050] Through the above adjustment mode, and because the adjusting shaft 5 is distributed on the circumferential line of the winding shaft 4, the position of tension, stretching or extrusion of the copper foil can be adjusted in the winding process, and the real-time winding condition is adjusted to solve the problem of manually adjusting the winding or completely stopping the operation of the adjusting assembly.
