Zinc coating electroplating system and electroplating method

Abstract

The invention relates to electroplating, in particular to a zinc coating electroplating system and electroplating method. The system comprises a frame, a hanging plate, a side plate, a supporting partand a wire, after the frame is close to the ground, the lower side of the frame can be pulled backwards, then the upper end of the frame can descend, the frame is changed from a vertical state into anearly horizontal reclining state, and parts can be placed in the supporting part at a low position conveniently. The frame is mounted on a ground base in an inclined lying manner, at the moment, thesupporting part faces downwards, a push plate is moved rightwards, a compression spring pushes an arc support to reset rightwards, the arc support pushes the parts to move rightwards to be separatedfrom a pipe, then the parts can be pulled out of the support part at a low position, and at the moment, the inclined part coincides with the end face of a protective pad, so that the parts are pulledout of the support part conveniently. Guide wheels are convenient for the frame to lie obliquely or bend over obliquely.

Description

technical field [0001] The invention relates to electroplating, more specifically to a zinc coating electroplating system and an electroplating method. Background technique [0002] For example, the publication number is CN111101171A, a jewelry electroplating process, which includes the following steps: 1) Ultrasonic equipment is first used to ultrasonically clean the jewelry, and then soaked in a pool for 30 to 60 minutes, followed by high-pressure washing with a high-pressure water spray gun; 2) Take out the jewelry , plate a layer of copper on the surface of the workpiece as a primer, wash with water after plating, acid activate, and wash with water; 3) Use ultrasonic waves to remove oil, wash with water, and then put it in dilute sulfuric acid for rust removal and activation; 4) Use electroplating solution to treat jewelry For electroplating treatment, the formulation of jewelry electroplating solution is as follows: stannous sulfate 81-85g / L, zinc sulfate 82-90g / L, amph...
