Method for enhancing binding force of nickel-plated layer of anti-tensile-folding part in wrist strap

Abstract

The invention discloses a method for enhancing the binding force of a nickel-plated layer of an anti-tensile-folding part in a wrist strap. The method comprises the steps that one end of the anti-tensile-folding part is placed in a plating tank, then following steps are carried out sequentially and continuously, specifically, stain removal is carried out on the anti-tensile-folding part in the wrist strap through process pretreatment; acid pickling is carried out on the anti-tensile-folding part after stain removal; sensitization and activation treatment is carried out on the anti-tensile-folding part subjected to stain removal and acid pickling; nickel pre-plating treatment is carried out on the end part of the anti-tensile-folding part subjected to sensitization and activation treatment;a nickel layer is plated at the end of the anti-tensile-folding part subjected to nickel pre-plating treatment; and the end, plated with the nickel layer, of the anti-tensile-folding part is dried. Through the technical scheme, the nickel layer can be well attached to the end of the anti-tensile-folding part, the binding force of the nickel layer and the end of the anti-tensile-folding part is extremely high, and the defects that the nickel plating layer falls off from the end of the anti-tensile-folding part and cracks cannot be caused.

Description

technical field [0001] The invention relates to the field of plating of metal parts, in particular to a method for enhancing the binding force of the nickel-plated layer of the anti-bending component in the wristband. Background technique [0002] Community correction is usually completed by using a positioning terminal with communication functions, such as a wristband, to be bound to the corrected person. For the wristband with communication function, as long as the wristband is always worn on the person to be corrected, the position of the wristband is the position of the person to be corrected. [0003] The strap of the wristband is built with two anti-bending parts, for example, a steel wire rope and the like. Since this component also has the function of electrical conduction, the end of this component needs to be welded together with the PCB, and in order to facilitate tinning, the end of this type of component that needs to be welded with the PCB is generally nickel-...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a method for enhancing the bonding force of the nickel-plated layer of the anti-tension part in the wristband, so as to solve the problem that the existing nickel-plating method or a certain step in it is not compliant and unscientific and causes the coating to fall off easily. defect
