Two-end tin-plating automatic production line

Abstract

The invention relates to a two-end tin-plating automatic production line. The two-end tin-plating automatic production line includes a loading device, a first cleaning device, a tin-plating tank, a second cleaning device and an unloading device which are successively connected; the tin-plating tank, the first cleaning device and the second cleaning device are all connected with a PLC and an exhausting system; the first cleaning device comprises an electrolysis oil-removing tank, a water washing tank, a pickling tank, a passivation tank and an activation tank; the second cleaning device comprises an ultrasonic cleaning and tank, a neutralization tank, a water washing tank and a dry-scalding tank; the electrolysis oil-removing tank, the pickling tank, the passivation tank, the activation tank, the tin-plating tank and the neutralization tank are each provided with a Feiba; the Feiba comprises a Feiba base, a tin-plating liquid box group, a Feiba frame, and a cover sheet covering the tin-plating liquid box group. Compared with the prior art, the two-end tin-plating automatic production line has controllable programming operation; wastewater is greatly reduced, and thus the wastewater treatment cost is reduced; the work environment is improved, and odor generated by chemical agents required for electroplating is directly discharged through an air treatment device via the exhausting system.

Description

technical field [0001] The invention belongs to the technical field of copper wire tinning, and in particular relates to an automatic production line for tinning at both ends. Background technique [0002] The process flow of tin plating on copper bars is: pre-polishing treatment → pure water washing → pickling passivation workpiece → drying water → JLR-510 protection treatment → washing with running water → hot water soaking (about 100 °C, used to heat up the workpiece, The purpose is to allow the moisture to evaporate or dry by itself) → drying → packaging and sealing. When pickling and passivation are treated separately, the method of immersing the workpiece as a whole in the pickling passivation solution is often used, which is suitable for small parts or pipelines and linear equipment that can circulate liquid inside. When combining pickling and passivation into one treatment, it can be soaked in liquid (the applicable range is the same as above), or it can be applied ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the products that are electroplated at both ends are manually operated, which greatly increases the probability of operators having safety problems due to the environment, temperature and on-site chemicals; in addition, in terms of operation, the standardization of product technology cannot be effectively controlled; In terms of consumption, the current operation method produces more wastewater, which increases the cost of wastewater treatment
