Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of evaporation, more specifically, relates to a wire feeding device. BACKGROUND

[0002] The working principle of vacuum evaporation coating technology is to make the metal material to be evaporated vaporize and evaporate by heating under vacuum condition, and then deposit on the substrate to be coated to form a thin film. The metal material is generally fed by a wire feeding device.

[0003] The existing wire feeding device generally comprises a wire feeding disc, a wire feeding assembly and a wire feeding pipe. The single wire for vacuum coating can be wound on the wire feeding disc. The wire feeding assembly comprises a driving motor, a driving roller and a driven roller arranged oppositely. A wire feeding gap matching the size of the wire is arranged between the driving roller and the driven roller. The driving motor is in transmission connection with the driving roller. The wire is unwound from the wire feeding disc and conveyed to the space between the driving roller and the driven roller. Then the driving motor drives the driving roller to rotate and cooperates with the driven roller to continuously convey the single wire to the evaporation boat through the guide of the wire feeding pipe for coating.

[0004] However, the existing wire feeding device feeds the wire into the evaporation boat at a fixed angle, and the wire feeding angle is fixed after the wire feeding device is installed and fixed. If the installation position of the wire feeding device deviates during the actual evaporation process, the wire falling point deviation will be large, which may cause the metal liquid in the evaporation boat to be too much in some areas and too little in some areas, thereby causing uneven evaporation and affecting the coating quality.
