[0002] Electroplating pretreatment is an indispensable part of electroplating processing, which is directly related to the quality of the electroplating layer and the final performance of the plated parts. If the pretreatment is improper, it may cause defects such as pinholes, peeling, and blistering in the plating layer, which will seriously affect the quality and service life of the product. Therefore, in electroplating processing, it is necessary to pay attention to the surface treatment of the plated parts to ensure the perfection and reliability of the pretreatment process.

[0003] The existing surface treatment devices for plated parts have the following problems: When the existing plated part surface treatment device performs chemical treatment on the plated part, the acidic solution will produce a large amount of volatile gas floating in the air, affecting the health and safety of the operators. In addition, when the traditional plated part chemical treatment device performs chemical treatment on the plated part surface, the concentration of the chemical solution will gradually decrease, thereby affecting the treatment efficiency of the chemical solution on the plated part surface. Therefore, it cannot meet the existing use requirements of the plated part surface treatment device. Summary of the invention

[0006] As a further preferred embodiment of the present invention, the fixing mechanism includes a processing cylinder, a sealing magnetic plate and a concave anti-slip block. Multiple groups of the processing cylinders are arranged on the side wall of the processing table. The processing cylinder is opened at the upper end. The sealing magnetic plate is arranged on the upper wall of the processing cylinder. The sealing magnetic plate is adsorbed on the upper wall of the processing cylinder by magnetic force. The concave anti-slip block is respectively arranged on the bottom wall of the sealing magnetic plate and the inner wall of the bottom of the processing cylinder; the rotating mechanism includes a rotating cylinder, a three-phase coil and a driving magnet. The rotating cylinder is arranged through the inner wall of the processing cylinder, and the rotating cylinder is rotatably arranged on the inner wall of the processing cylinder. Multiple groups of the three-phase coils are arranged on the outside of the rotating cylinder, and multiple groups of the driving magnets are arranged on the inner wall of the processing cylinder close to one end of the rotating cylinder. The three-phase coil and the driving magnet are arranged horizontally opposite to each other; the grinding mechanism includes an acid-passing plate and an acid-resistant abrasive layer. Multiple groups of the acid-passing plates are arranged between the processing cylinder and the inner wall of the rotating cylinder, and the acid-resistant abrasive layer is arranged on the side of the acid-passing plate away from the inner wall of the processing cylinder and the rotating cylinder.

[0007] When in use, the sealing magnetic plate is removed from the upper wall of the processing cylinder, and the shaft-type plated parts to be processed are placed on the upper wall of the concave anti-slip block at the bottom of the processing cylinder. The shaft-type plated parts are placed inside the processing cylinder and fit with the acid-resistant abrasive layer. The sealing magnetic plate is reset to the upper wall of the processing cylinder, and the sealing magnetic plate is adsorbed on the upper wall of the processing cylinder by magnetic force. The shaft-type plated parts to be processed are clamped between the concave anti-slip blocks. The three-phase coil is energized to generate magnetism, and the rotating cylinder rotates in a circle under the action of the magnetic field between the three-phase coil and the driving magnet. The rotating cylinder drives the acid-resistant abrasive layer through the acid-passing plate to remove the oxide scale and rust on the side wall of the shaft-type plated parts.

[0008] Preferably, the liquid extraction mechanism includes a liquid extraction pump, a liquid delivery pipe, a spring tube and an enamel heating rod. Multiple groups of the liquid extraction pumps are arranged on the upper wall of the hydrochloric acid cylinder. The liquid extraction end of the liquid extraction pump is arranged inside the hydrochloric acid cylinder. The liquid delivery pipe is arranged at the liquid discharge end of the liquid extraction pump. The spring tube is connected between the liquid delivery pipe and the sealing magnetic plate. The enamel heating rod is arranged on the side wall of the hydrochloric acid cylinder. The heating end of the enamel heating rod is arranged inside the hydrochloric acid cylinder. The liquid discharge mechanism includes a support tube, a reflux cylinder and a liquid discharge tube. The support tube is arranged on the hydrochloric acid cylinder. The bottom wall of the acid cylinder, the reflux cylinder is arranged on the bottom wall of the support tube, the reflux cylinder is connected with the support tube, the discharge pipe is connected between the bottom wall of the treatment cylinder and the upper side wall of the reflux cylinder; the filtering mechanism includes a filter screen, a filter pump and a circulation pipe, the filter pump passes through the treatment table and is arranged on the side wall of the hydrochloric acid cylinder, the discharge end of the filter pump passes through the inside of the hydrochloric acid cylinder, the circulation pipe is connected between the bottom side wall of the reflux cylinder and the liquid suction end of the filter pump, and the filter screen is arranged on the inner wall of the reflux cylinder between the discharge pipe and the circulation pipe.

[0009] When in use, the enamel heating rod heats the hydrochloric acid inside the hydrochloric acid cylinder to accelerate the pickling speed of the shaft-type plated parts with hydrochloric acid. The liquid extraction pump extracts the hydrochloric acid liquid inside the hydrochloric acid cylinder through the liquid extraction end, and the hydrochloric acid liquid flows into the treatment cylinder and the rotating cylinder through the liquid delivery pipe and the spring tube. The liquid level of the hydrochloric acid liquid inside the treatment cylinder and the rotating cylinder continues to rise, and the shaft-type plated parts are completely immersed in the hydrochloric acid liquid. The oxide scale and rust on the surface of the shaft-type plated parts fall off under the chemical treatment of the hydrochloric acid liquid. As the acid-passing plate drives the acid-resistant abrasive layer to rub against the surface of the shaft-type plated parts, the oxidized impurities on the surface of the shaft-type plated parts can be quickly removed. The hydrochloric acid liquid inside the treatment cylinder and the rotating cylinder flows into the reflux cylinder through the discharge pipe. The hydrochloric acid liquid transported from the treatment cylinder and the rotating cylinder to the reflux cylinder falls into the bottom of the reflux cylinder after being filtered by the filter screen, and then the filter pump draws the filtered hydrochloric acid liquid back to the hydrochloric acid cylinder through the circulation pipe.

[0010] Specifically, the gas storage mechanism includes a gas storage rack and a gas storage cylinder, the gas storage rack is arranged on the upper wall of the hydrochloric acid cylinder, and the gas storage cylinder is arranged at one end of the gas storage rack away from the hydrochloric acid cylinder; the reaction mechanism includes an exhaust pump, an exhaust pipe and an exhaust valve, the exhaust pump is arranged on the top side wall of the gas storage cylinder, the exhaust pump suction end is arranged through the inside of the gas storage cylinder, the exhaust pipe is connected between the exhaust end of the exhaust pump and the support pipe, and the exhaust valve is connected to the side wall of the support pipe.

[0011] When in use, the increase in the temperature of hydrochloric acid will accelerate its volatilization. When hydrochloric acid volatilizes, it will release hydrogen chloride gas, which will affect the health and safety of operators. Therefore, it is necessary to degrade the concentration of the generated hydrogen chloride gas. Hydrogen chloride gas itself is an acidic gas. After dissolving in water, it will form hydrochloric acid, which is acidic. The scale and rust that fall off from the surface of the shaft-type plated parts are intercepted by the filter in the upper space of the reflux cylinder. The exhaust pump extracts the hydrogen chloride gas inside the gas storage cylinder through the suction end, and the hydrogen chloride gas inside the gas storage cylinder enters the support tube through the exhaust pipe. The hydrogen chloride gas inside the support tube is discharged into the reflux cylinder and contacts with the scale and rust stored on the wall of the filter. Since hydrochloric acid remains on the surface where the scale and rust contact, the hydrochloric acid reacts with the scale and rust to produce moisture. When the hydrogen chloride gas entering the reflux cylinder contacts the moisture on the surface of the scale and rust, hydrochloric acid is formed, thereby reducing the concentration of the volatilized hydrogen chloride gas in the hydrochloric acid liquid.

[0012] Preferably, a controller is provided on the side wall of the hydrochloric acid cylinder.

[0013] Furthermore, the controller is electrically connected to the three-phase coil, the liquid extraction pump, the impurity filter pump and the exhaust pump respectively.

[0014] A method for using a surface treatment device for electroplating, the steps are as follows: Step 1: The plated shaft parts are placed inside the treatment cylinder and fit with the acid-resistant abrasive layer. The sealing magnetic plate is reset to the upper wall of the treatment cylinder. The sealing magnetic plate is adsorbed on the upper wall of the treatment cylinder by magnetic force. The plated shaft parts to be treated are clamped between the concave anti-sliding blocks. The three-phase coil is energized to generate magnetism. The rotating cylinder rotates in a circle under the force of the magnetic field between the three-phase coil and the driving magnet. Step 2: The enamel heating rod heats the hydrochloric acid inside the hydrochloric acid cylinder to speed up the pickling speed of the shaft-type plated parts by the hydrochloric acid. The liquid pump extracts the hydrochloric acid liquid inside the hydrochloric acid cylinder through the liquid extraction end. The hydrochloric acid liquid flows into the treatment cylinder and the rotating cylinder through the liquid delivery pipe and the spring tube. The liquid level of the hydrochloric acid liquid inside the treatment cylinder and the rotating cylinder continues to rise. The shaft-type plated parts are completely immersed in the hydrochloric acid liquid. The oxide scale and rust on the surface of the shaft-type plated parts fall off under the chemical treatment of the hydrochloric acid liquid. Step 3: The exhaust pump extracts the hydrogen chloride gas in the gas cylinder through the exhaust end, and the hydrogen chloride gas in the gas cylinder enters the support tube through the exhaust pipe. The hydrogen chloride gas in the support tube is discharged into the reflux tube and contacts the oxide scale and rust on the upper wall of the filter.

[0015] The beneficial effects achieved by adopting the above structure are as follows: Compared with the prior art, the present invention adopts a method of combining heating the chemical treatment liquid with collecting the volatile acid gas. Through the provided rotating positioning mechanism, circulating impurity rate mechanism and gas collection type acid elimination mechanism, under the coordinated use of the fixing mechanism, rotating mechanism, grinding mechanism, liquid extraction mechanism, liquid discharge mechanism, impurity filtering mechanism, gas storage mechanism and reaction mechanism, on the one hand, the concentration of hydrogen chloride gas volatilized in the hydrochloric acid liquid can be reduced to avoid the influence of hydrogen chloride gas on the health and safety of the operators. On the other hand, the conversion ratio of ferric oxide to ferric chloride can be increased. When ferric chloride and hydrochloric acid coexist, due to the water content of ferric chloride, the concentration of hydrogen chloride gas volatilized in the hydrochloric acid liquid can be reduced. The hydrolysis effect will further increase the hydrogen ion concentration in the solution, thereby increasing the acidity of the solution, and then make up for the problem of reduced acidity due to the addition of water to hydrochloric acid. The shaft-plated parts are completely immersed in the hydrochloric acid liquid, and the oxide scale and rust on the surface of the shaft-plated parts fall off under the chemical treatment of the hydrochloric acid liquid. As the acid-passing plate drives the acid-resistant abrasive layer to rub against the surface of the shaft-plated parts, the oxidized impurities on the surface of the shaft-plated parts can be quickly removed, and the hydrochloric acid liquid inside the treatment cylinder and the rotating cylinder flows into the reflux cylinder through the drain pipe. The hydrochloric acid liquid transported from the treatment cylinder and the rotating cylinder to the reflux cylinder falls to the bottom of the reflux cylinder after being filtered by the filter.

[0026] The controller 36 is electrically connected to the three-phase coil 10 , the liquid pump 17 , the impurity filter pump 26 and the exhaust pump 33 , respectively.

[0027] A method for using a surface treatment device for electroplating, the steps are as follows: Step 1: The plated shaft parts are placed inside the treatment cylinder 5 and fit with the acid-resistant abrasive layer 14. The sealing magnetic plate 6 is reset to the upper wall of the treatment cylinder 5. The sealing magnetic plate 6 is adsorbed on the upper wall of the treatment cylinder 5 by magnetic force. The plated shaft parts to be treated are clamped between the concave anti-sliding blocks 7. The three-phase coil 10 is energized to generate magnetism. The rotating cylinder 9 rotates in a circle under the force of the magnetic field between the three-phase coil 10 and the driving magnet 11. Step 2: The enamel heating rod 37 heats the hydrochloric acid inside the hydrochloric acid cylinder 2 to speed up the pickling speed of the shaft-type plated parts by the hydrochloric acid. The liquid pump 17 extracts the hydrochloric acid liquid inside the hydrochloric acid cylinder 2 through the liquid extraction end. The hydrochloric acid liquid flows into the processing cylinder 5 and the rotating cylinder 9 through the liquid delivery pipe 18 and the spring tube 19. The liquid level of the hydrochloric acid liquid inside the processing cylinder 5 and the rotating cylinder 9 continues to rise. The shaft-type plated parts are completely immersed in the hydrochloric acid liquid. The oxide scale and rust on the surface of the shaft-type plated parts fall off under the chemical treatment of the hydrochloric acid liquid. Step 3: The exhaust pump 33 extracts the hydrogen chloride gas in the gas storage cylinder 31 through the exhaust end, and the hydrogen chloride gas in the gas storage cylinder 31 enters the support tube 21 through the exhaust pipe 34. The hydrogen chloride gas in the support tube 21 is discharged into the reflux tube 22 and contacts the oxide scale and rust stored on the upper wall of the filter screen 25.

[0028] When in use, in the initial state, the spring tube 19 is in an extended setting, the sealing magnetic plate 6 is in contact with the upper wall of the processing tube 5, and the processing tube 5 is in a sealed state. When the surface of the plated part to be electroplated needs to be processed, the sealing magnetic plate 6 is removed from the upper wall of the processing tube 5 by utilizing the deformation of the spring tube 19, and the shaft-type plated part to be processed is placed on the upper wall of the concave anti-sliding block 7 at the bottom of the processing tube 5. The shaft-type plated part is placed inside the processing tube 5 and is in contact with the acid-resistant abrasive layer 14. The sealing magnetic plate 6 is placed in the upper wall of the processing tube 5, and the sealing magnetic plate 6 is reset to the upper wall of the processing tube 5. The sealing magnetic plate 6 is adsorbed on the upper wall of the processing tube 5 by magnetic force, and the shaft-type plated part to be processed is clamped between the concave anti-sliding blocks 7; The controller 36 controls the enamel heating rod 37 to start, and the enamel heating rod 37 heats the hydrochloric acid inside the hydrochloric acid cylinder 2, which can speed up the pickling speed of the shaft-type plated parts by the hydrochloric acid. The controller 36 controls the liquid extraction pump 17 to start, and the liquid extraction pump 17 extracts the hydrochloric acid liquid inside the hydrochloric acid cylinder 2 through the liquid extraction end. The hydrochloric acid liquid flows into the processing cylinder 5 and the rotating cylinder 9 through the liquid delivery pipe 18 and the spring tube 19. The liquid level of the hydrochloric acid liquid inside the processing cylinder 5 and the rotating cylinder 9 continues to rise, and the shaft-type plated parts are completely immersed in the hydrochloric acid liquid. The oxide scale and rust on the surface of the shaft-type plated parts fall off under the chemical treatment of the hydrochloric acid liquid. The controller 36 controls the three-phase coil 10 to start, and the three-phase coil 10 is energized to generate magnetism. The rotating cylinder 9 rotates in a circle under the force of the magnetic field between the three-phase coil 10 and the driving magnet 11. The rotating cylinder 9 drives the acid-resistant abrasive layer 14 through the acid-passing plate 13 to remove the oxide scale and rust on the side wall of the shaft-type plated parts. As the acid-passing plate 13 drives the acid-resistant abrasive layer 14 to rub against the surface of the shaft-type plated parts, the oxidized impurities on the surface of the shaft-type plated parts can be quickly removed. The hydrochloric acid liquid inside the treatment cylinder 5 and the rotating cylinder 9 flows into the reflux cylinder 22 through the drain pipe 23. The hydrochloric acid liquid transported from the treatment cylinder 5 and the rotating cylinder 9 to the reflux cylinder 22 falls to the bottom of the reflux cylinder 22 after being filtered by the filter screen 25. Then the controller 36 controls the filter pump 26 to start, and the filter pump 26 draws the filtered hydrochloric acid liquid back to the hydrochloric acid cylinder 2 through the circulation pipe 27. The increase in the temperature of hydrochloric acid will accelerate its volatilization. When hydrochloric acid volatilizes, it will release hydrogen chloride gas, which will affect the health and safety of operators. Therefore, it is necessary to degrade the concentration of the generated hydrogen chloride gas. Hydrogen chloride gas itself is an acidic gas. After dissolving in water, it will form hydrochloric acid, which is acidic. The oxide scale and rust that fall off from the surface of the shaft-type plated parts are intercepted by the filter 25 in the upper space of the reflux tube 22. The controller 36 controls the exhaust pump 33 to start. The exhaust pump 33 extracts the hydrogen chloride gas in the gas storage cylinder 31 through the exhaust end. The hydrogen chloride gas in the gas storage cylinder 31 enters the support tube 21 through the exhaust pipe 34. The support tube 21 The internal hydrogen chloride gas is discharged into the reflux drum 22 and contacts with the oxide scale and rust stored on the upper wall of the filter screen 25. Since hydrochloric acid is retained on the surface where the oxide scale and rust contact, the hydrochloric acid reacts with the oxide scale and rust to produce moisture. When the hydrogen chloride gas entering the reflux drum 22 contacts with the moisture on the surface of the oxide scale and rust, hydrochloric acid is formed, which reduces the concentration of volatile hydrogen chloride gas in the hydrochloric acid liquid. At the same time, the hydrolysis of ferric chloride is utilized to increase the concentration of hydrogen ions in the solution, thereby increasing the acidity of the solution. The exhaust valve 35 is opened to discharge the volatile gas with reduced concentration inside 22. The above operation can be repeated the next time it is used.
