Description

Technical Field

[0001] The present application relates to the technical field of electroplating processing, and in particular to a surface treatment device for plated parts used in electroplating processing. Background Art

[0002] Electroplating is a process of coating a metal surface with one or more layers of metal to improve the metal's corrosion resistance, wear resistance, decorativeness or other special properties. Pretreatment is a crucial step in electroplating. It uses a series of chemical and physical methods to thoroughly clean the workpiece surface, remove impurities such as grease, dirt, oxides, and activate the workpiece surface to improve the activity and roughness of the workpiece surface, thereby enhancing the bonding force between the subsequent coating and the workpiece substrate, ensuring the uniformity, adhesion and overall quality of the coating. Among them, the pickling step is to use an acidic solution to remove the oxide scale and rust on the metal surface. Commonly used acids include sulfuric acid, hydrochloric acid, phosphoric acid, etc. Neutralization is also required after pickling to remove the acidic substances remaining on the metal surface after pickling. Weak alkaline solutions are usually used.

[0003] The existing surface treatment device for electroplating has some shortcomings. In order to maintain the pretreatment efficiency, the pickling time is generally very short, which results in the impurities on the surface of the plated part not being reacted completely, resulting in incomplete surface treatment of the plated part. Although the pretreatment efficiency is improved, the accuracy of the pretreatment is reduced. Therefore, a surface treatment device for electroplating is needed. Summary of the invention

[0020] Working principle: First, put the plated parts into the feed port of the pickling tank, then start the motor, the motor drives the transmission roller 1 at the bottom to rotate through two meshing gears, so that the transmission roller 1 drives another transmission roller 1 connected by the taut blade mesh belt, so that the other transmission roller 1 rotates, while the transmission roller 1 at the bottom rotates, it drives the quantitative roller to rotate through two pulleys of different sizes connected by belts, so that the plated parts put into the feed port of the pickling tank will fall into the quantitative groove of the quantitative roller when the quantitative roller rotates, and transfer with the rotation of the quantitative roller until the quantitative groove moves to the bottom, so that the quantitative plated parts inside the quantitative groove are The plated piece falls onto the surface of the mesh plate in the retention chamber and stays inside the retention chamber for a period of time, thereby being soaked by the acid cleaning liquid inside the pickling tank to remove impurities on the surface of the plated piece. When the pulley at the top rotates a certain angle, the tooth meshing gear on the outer peripheral surface rotates, causing the angle of the mesh plate to change and the plane to tilt, so that the plated piece falls onto the inclined plate on the bottom side and slides onto the blade mesh belt. It is transported obliquely upward through the blade support on the surface of the blade mesh belt and leaves the inside of the pickling tank. Then, the plated piece moves to the top of the blade mesh belt and leaves the support of the blade, so that the plated piece falls on the unloading plate and falls on the surface of the draining mesh belt along the inclined surface of the unloading plate. The top transmission roller 1 is connected to multiple synchronous wheels through a synchronous belt, and the transmission roller 2 at the last end rotates and the rotating rod rotates, so that the taut drain mesh belt driven by the transmission roller 2 at the rear end is displaced, so that the plated parts on the surface of the drain mesh belt are transported forward, and the rotating rotating rod is rotated through two mutually meshing bevel gear transmission power rods. The rotating power rod drives the gear 2 connected to it to rotate synchronously, so that it meshes with another gear 2 connected to the connecting rod to rotate, so that the connecting rod pushes and pulls the piston connected to it to move up and down reciprocatingly, thereby changing the pressure inside the cylinder connected to the negative pressure tank where the piston slides, thereby changing the internal pressure of the negative pressure tank, and causing the elasticity at the input end of the negative pressure tank to change. The spring one-way valve opens to generate negative pressure at the input port of the liquid inlet pipe on the recovery tank through the delivery pipe, and the alkaline cleaning liquid inside the recovery tank is pumped into the interior of the negative pressure tank. After the piston is pressed down, the interior of the negative pressure tank is pressurized, so that the alkaline cleaning liquid inside the negative pressure tank is guided to the one-way valve at the output end of the negative pressure tank, so that the one-way valve opens, and under pressure, the alkaline cleaning liquid enters the infusion pipe through the delivery pipe and is sprayed out from the nozzle in the infusion pipe. The infusion pipe at the top sprays the surface of the plated component, and the infusion pipe at the bottom end located in the drain mesh belt sprays the side of the plated component that contacts the drain mesh belt, so that the plated component is cleaned in all directions and the acidic cleaning liquid remaining on the surface of the plated component is removed.

[0043] Specifically, the pickling tank 1 is used to contain the acid cleaning liquid for pickling plated parts. The hollow mesh-structured blade mesh belt 9 can continue to fully immerse the plated parts in the cleaning liquid while conveying the plated parts, so that the plated parts material put into the feed port of the pickling tank 1 will fall into the quantitative groove of the quantitative roller 3 when the quantitative roller 3 rotates, and is transferred with the rotation of the quantitative roller 3 until the quantitative groove moves to the bottom, so that the quantitative plated parts material inside the quantitative groove falls into the surface of the mesh plate 4 in the retention chamber, and is retained in the retention chamber for a period of time, thereby being immersed in the acid cleaning liquid in the pickling tank 1, so that the impurities on the surface of the plated parts can be fully reacted. When the top pulley 11 rotates a certain angle, it will be meshed with the teeth on the outer surface.
