The invention relates to a rubber-covered wire peeling and cutting device for circular circuit board welding equipment. The device comprises a wire combing assembly, a wire cutting assembly, a wire clamping assembly and a wire winding assembly; the wire combing assembly, the wire cutting assembly and the wire winding assembly are sequentially arranged and located on the same straight line; the wire clamping assembly is installed beside the wire cutting assembly; the wire clamping assembly is corresponding to the wire winding assembly; the wire combing assembly is used for combing fed rubber-covered wires; the wire cutting assembly is used for cutting and peeling the rubber-covered wires; the wire clamping assembly is used for clamping one ends of the rubber-covered wires and moving the rubber-covered wires; and the wire winding assembly is used for clamping the other ends of the rubber-covered wires and rotationally winding two of the rubber-covered wires. With the rubber-covered wirepeeling and cutting device for the circular circuit board welding equipment of the invention adopted, the feeding of the rubber-covered wires is stable; two rubber-covered wires can be twisted into one strand; and the cutting and peeling of the rubber-covered wires are achieved. The device is suitable for automatic production.
