Description

Technical Field

[0001] The invention relates to the technical field of transformer processing, in particular to an adhesive tape wrapping mechanism for transformer processing. Background Art

[0002] When the transformer is processed and the first wire is wound, the engineering data will require us to wrap a circle of pre-wrapped tape on the empty skeleton first. This circle of tape has the following functions: 1. Prevent the mold line on the skeleton from scratching the copper wire. Generally, there will be a mold line on the skeleton, where burrs will be generated. If the burrs are not completely removed during the production process of the skeleton, the lacquer film of the copper wire will be scratched, causing high voltage and ARC and other hidden dangers. 2. Improve the withstand voltage and prevent defects. The middle of the skeleton is where the CORE is inserted. Due to the presence of a mold line in the middle of the skeleton or being squeezed during the subsequent production process, a small crack appears in the skeleton. The copper wire is directly wound on the skeleton. If the primary side is defective to the magnetic core, the secondary side is close to the magnetic core, which will also cause high voltage defects in the product. 3. Reduce leakage current. By filling a layer of tape, the j parasitic capacitance on the primary side of the transformer will be reduced. This can reduce the leakage current of the transformer. The leakage current of the transformer will increase the additional loss of the transformer, causing the transformer to heat up and the transmission power to decrease. 4. It is easy to arrange the wires and wind them tightly. Generally, the first winding is the primary winding, which has many turns and often requires multiple layers of dense winding. The inner wall of the frame is plastic and very smooth. Adding a layer of tape can make it easier to arrange the first winding of the transformer and prevent the occurrence of wire pile-up.

[0003] However, the existing tape wrapping equipment is driven by several driving mechanisms, which is costly. In addition, the driving mode of multiple driving mechanisms is prone to rhythm confusion, which affects the efficiency of tape wrapping. Summary of the invention
