Description

Technical Field

[0001] The invention relates to the technical field of motor production, in particular to a device for automatically removing residual demoulding tape of a hydroelectric stator coil after linear gelation. Background Art

[0002] As my country has pledged to achieve carbon peak in 2030 and carbon neutrality in 2060, my country's energy supply structure is undergoing profound changes. Specifically in the power industry, the development of thermal power will be suppressed, and clean green electricity such as solar power generation, wind power, hydropower, and nuclear power will usher in a period of rapid development. The production rate of traditional hydropower stator coils is high, especially the production process of wires is almost entirely dependent on manual production; the motor coil is generally wound with hot-melt insulated flat copper wire. During its production process, the straight section of the motor coil embedded in the wire slot must be heated until the glue outside the insulation layer melts, and then pressurized and cooled to form a solidified insulation layer. The motor coils can be firmly combined. For portable demolding, a demolding tape made of polytetrafluoroethylene material will be used to pad the coil body before the straight line is gelled; after the straight line is gelled, the demolding needs to be removed and the tape needs to be polished for the overflow glue and right angles of the coil. In traditional production, operators will use a knife to cut the demolding tape, and manually polish and chamfer. The manual work is large, inefficient, and the work form is single, which can no longer meet current production needs. Summary of the invention
