Description

Technical Field

[0001] The utility model relates to the technical field of copper wire processing, in particular to a copper wire tinning processing device. Background Art

[0002] The main purpose of tinning copper wire is to prevent copper from being oxidized when exposed to air to form a layer of film (patina). The resulting patina has poor conductivity and will increase resistance. Tinned copper wire can prevent redox reactions; increase heat dissipation; improve conductivity and wire performance;

[0003] The prior art refers to a surface tinning device for copper wire processing disclosed in announcement number CN113957450A, in which the position of the movable plate is fixed by a sliding sleeve, so that the pressing plate and the second fixed pulley keep pressing the copper wire into the processing frame, so that the copper wire can be fully in contact with the liquid in the processing frame. While winding the copper wire, the movable frame drives the third fixed pulley to move forward and backward continuously, thereby driving one end of the copper wire to move forward and backward, so that the winding drum can wind the copper wire more neatly;

[0004] However, the existing technology only directly contacts the copper wire with the tin liquid, and the tin plating on the surface of the copper wire will be uneven during the tinning process. In addition, the radius of each layer of wire wound on the winding component is different during the winding process of the copper wire, and the wire will become thicker and thicker. The existing technology directly uses a movable frame and a fixed pulley for winding, which will cause the copper wire to be easily tangled together. For this reason, we designed a copper wire tinning processing equipment. Utility Model Content
