The invention discloses a wiring auxiliary structure of a screen FPC end and a screen lightening detection process, the structure comprises an epitaxial bearing platform, a base, a wiring platform, a needle die, a pressing module, a jacking module and a beating and aligning
assembly, the pressing module comprises a pressing die strip and a power device, the needle die and the wiring platform are in
butt joint to form a stepped matching surface, and the needle die is also provided with an air leakage channel. On one hand, the FPC end is flattened on the basis of negative pressure adsorption force formed by the downward pressing die strip in combination with movement in the up-down and front-back directions, meanwhile, position calibration of the flattened FPC end is conducted on the basis of left-right patting, and under the matched pressing fit of a matching face and the screen FPC end, accurate
butt joint of an interface and a needle die is achieved, the
butt joint dislocation rate is reduced, and potential safety hazards are eliminated; and on the other hand, the air flow formed by lamination is discharged based on the air leakage channel, lamination hollowing is avoided, the butt
joint stability of the interface and the needle mold is improved, the displacement rate of the interface and the needle mold is reduced, and therefore the accuracy rate of the screen lightening test is improved.
