Description

Technical Field

[0001] The utility model relates to the technical field of chemical electroplating, in particular to a stirring electroplating tank. Background Art

[0002] An electroplating tank is a container used for electroplating parts. During the electroplating process of parts, a protective layer is evenly plated on the surface of the parts to facilitate the protection of the parts. Due to the nature of the electroplating solution itself, during electroplating, the ion distribution in the electroplating solution is not uniform and requires external force to regulate.

[0003] A patent with the publication number CN 210438860 U discloses a self-circulating stirring electroplating tank, including a tank body and a motor. A base is provided at the center inside the tank body, a suction head is provided inside the outer cover, a wind blade is installed inside the suction head, a water flow hole is opened inside the connecting column, the motor is arranged below the tank body, and a rotating shaft is connected to the top of the motor. The top of the rotating shaft is connected to a wind blade, and a stirring blade is arranged outside the rotating shaft. This self-circulating stirring electroplating tank is convenient for stirring the electroplating solution in the electroplating tank, can control the electroplating solution to flow in one direction, is convenient for the ions in the electroplating solution to be evenly distributed, and can extract the liquid at the bottom of the electroplating solution, so that the ion concentrations at different depths of the electroplating solution are the same.

[0004] In the process of using the existing electroplating tank, the stirring effect is not good. The electroplating solution inside the traditional electroplating tank will be recycled and absorbed, and the electroplating solution is recycled and used. However, due to different material materials each time, certain dust impurities, burr debris and other substances will remain on the surface of each new material and will remain inside the electroplating solution. These burr impurities are difficult to effectively clean up later. Moreover, when the electroplating solution is recycled and reused, the dust impurities inside the electroplating solution will block the inside of the return pipe and the cooling pipe, making the electroplating tank prone to pipeline blockage and equipment damage during use, reducing the production efficiency of the product. Summary of the Utility Model

[0005] Therefore, the technical problem to be solved by the present utility model is to overcome the problem in the prior art that each newly added material will leave burr impurities on the surface inside the electroplating solution, so that during the recycling of the electroplating solution, as the electroplating solution continuously flows, the dust impurities inside the electroplating solution will block the inside of the return pipe and the cooling pipe, making the electroplating tank prone to pipeline blockage and equipment damage during use, reducing the production efficiency of the product.

A condenser is fixedly installed on the top surface of the lapping support platform and at one edge position of the electroplating box. A reflux pipe fixedly installed on the input end of the condenser extends through the lapping support platform to the inner wall surface of the bottom of the electroplating box. A diversion hose is fixedly installed on the output end of the condenser. A gantry support frame arranged at the top edge position of the aggregate box is movably sleeved on the top edge position of the electroplating box, and the other end of the diversion hose is arranged on the outer surface of the gantry support frame. A diversion groove plate is fixedly installed on the top surface of the lapping support plate. An arc-shaped groove is formed on the top surface of the diversion groove plate. A rectangular groove is formed on the surface of the lapping support plate and at the bottom edge position of the arc-shaped groove. A filter strip is detachably installed on the inner wall surface of the rectangular groove.

[0007] In an embodiment of the utility model, limit track strips are fixedly installed on the outer surfaces of both sides of the electroplating box and at the top edge position, and the outer surface of the gantry support frame is movably sleeved on the inner wall surface of the limit track strips.

[0008] In an embodiment of the utility model, threaded rods are fixedly installed on the outer surfaces of both sides of the electroplating box and at the bottom edge position of the limit track strips. A slider fixedly installed on the outer surface of the gantry support frame is threadedly and movably sleeved on the outer surface of the output end of the threaded rods.

[0009] In an embodiment of the utility model, a motor is fixedly installed on the bottom surface of the gantry support frame.

[0010] In an embodiment of the utility model, a notch is formed on the bottom surface of the aggregate box. Elastic wires are fixedly connected to the two side edge positions of the bottom of the aggregate box.

[0011] In an embodiment of the utility model, a limiting plate arranged at the top edge position of the elastic wire is movably sleeved on the inner wall surface of the aggregate box. Clamping support strips are arranged on the inner wall surfaces of both sides of the limiting plate.

[0012] In an embodiment of the utility model, one end of the reflux pipe extends through the electroplating box to the bottom edge position of the lapping support plate.

[0013] In an embodiment of the present utility model, a housing is detachably installed at the top edge position of the clamping support bar, and a sunken limiting bar is provided at the bottom edge position of the housing.

[0014] The above technical solution of the present utility model has the following advantages compared with the prior art:

[0015] For a stirring electroplating tank of the present utility model, a condenser is used to fill the inside of the diversion hose with electroplating solution, and then a gantry support frame is used to limit the position of one end of the diversion hose, so that the electroplating solution discharged from the diversion hose can fall from the top of the aggregate tank. At the same time, a condenser is used to absorb the electroplating solution inside the return pipe, and then the return pipe is used to absorb the electroplating solution at the bottom end of the electroplating tank, so that the electroplating solution inside the electroplating tank forms a state of flowing from top to bottom. When the electroplating solution flows, it will flow quickly on the surface of the aggregate tank. When the electroplating solution passes through the inside of the aggregate tank, the fluidity of the water source is used to clean the dust, impurities, burrs and debris on the surface of the material.

[0016] For a stirring electroplating tank of the present utility model, when the electroplating solution flows quickly from top to bottom, the overlapping support plate on the inner side wall surface of the electroplating tank is used to quickly divide and contact the flowing electroplating solution. The arc-shaped groove on the inner side wall surface of the diversion groove plate is used to concentrate and contract the electroplating solution at the top, so that the contracted electroplating solution passes through the arc-shaped groove and enters the inside of the rectangular groove. At this time, the filter strip on the inner side wall surface of the rectangular groove is used to filter the quickly flowing electroplating solution. At the same time, the barbs on the inner side wall surface at the top of the filter strip are used to prevent the burrs, debris, dust and impurities inside the filter strip from flowing out of the filter strip again due to the backflow of the electroplating solution and driving the burrs, debris, dust and impurities inside the filter strip by the electroplating solution.

[0017] For a stirring electroplating tank of the present utility model, a condenser is used to absorb the electroplating solution inside the return pipe, and then the return pipe is used to absorb the electroplating solution at the bottom end of the electroplating tank. When the electroplating solution inside the return pipe enters the condenser, the condenser is used to quickly cool the remaining temperature inside the electroplating solution, and then the cooled electroplating solution is re-injected into the inside of the diversion hose. After the low-temperature electroplating solution is mixed into the electroplating tank, it can quickly cool the electroplating inside the electroplating tank. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0027] The present utility model will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited are not intended to limit the present utility model.

[0028] Refer to Figure 1 - Figure 7As shown in the figure, a stirring electroplating tank of the utility model includes a lapping support platform 11 and an electroplating box 12 fixedly installed on the outer surface of the top of the lapping support platform 11. An aggregate box 13 is detachably installed on the inner wall surfaces on both sides of the electroplating box 12. A lapping support plate 14 is detachably installed on the inner wall surface of the electroplating box 12 and is located at the bottom edge position of the aggregate box 13. A condenser 111 is fixedly installed on the top surface of the lapping support platform 11 and is located at one edge position of the electroplating box 12. A reflux pipe 112 is fixedly installed on the input end of the condenser 111 and extends through the lapping support platform 11 to the inner wall surface at the bottom of the electroplating box 12. A diversion hose 113 is fixedly installed on the output end of the condenser 111; A gantry support frame 124 arranged at the top edge position of the aggregate box 13 is movably sleeved on the top edge position of the electroplating box 12, and the other end of the diversion hose 113 is arranged on the outer surface of the gantry support frame 124; A diversion trough plate 141 is fixedly installed on the top surface of the lapping support plate 14. An arc-shaped groove 144 is formed on the top surface of the diversion trough plate 141. A rectangular groove 142 is formed on the surface of the lapping support plate 14 and is located at the bottom edge position of the arc-shaped groove 144. A filter strip 143 is detachably installed on the inner wall surface of the rectangular groove 142;

[0029] Put the electroplating materials into the interior of the aggregate box 13, and then immerse the aggregate box 13 into the cathode electroplating bath. At the same time, cooperate with the electroplating solution inside the electroplating box 12 to completely immerse the materials inside the aggregate box 13. Connect the electroplating materials to the anode of the power supply, and the cathode is connected to the negative electrode. After power on, the metal ions in the electroplating solution move to the cathode under the action of the potential difference to form a coating. At the same time, cooperate with the condenser 111 to fill the interior of the diversion hose 113 with electroplating solution, and then limit the position of one end of the diversion hose 113 through the gantry support frame 124, so that the electroplating solution discharged from the diversion hose 113 can fall from the top of the aggregate box 13. At the same time, cooperate with the condenser 111 to absorb the electroplating solution inside the reflux pipe 112, and then use the reflux pipe 112 to absorb the electroplating solution at the bottom end of the electroplating box 12, so that the electroplating solution inside the electroplating box 12 forms a state of flowing from top to bottom. When the electroplating solution flows, it will flow rapidly on the surface of the aggregate box 13. When the electroplating solution passes through the interior of the aggregate box 13, the dust impurities and burr debris on the surface of the materials can be cleaned off by the fluidity of the water source;

[0030] When the electroplating solution flows rapidly from top to bottom, it cooperates with the overlapping support plate 14 on the inner side wall of the electroplating tank 12 to make rapid differential contact with the flowing electroplating solution. The arc-shaped groove 144 on the inner side wall of the diversion groove plate 141 concentrates and contracts the electroplating solution at the top, so that the contracted electroplating solution passes through the arc-shaped groove 144 and enters the interior of the rectangular groove 142. At this time, the filter strip 143 on the inner side wall of the rectangular groove 142 is used to filter the rapidly flowing electroplating solution. At the same time, in cooperation with the barbs on the inner side wall of the top of the filter strip 143, it is avoided that the burr debris, dust and impurities inside the filter strip 143 will not flow out of the interior of the filter strip 143 again due to the backflow of the electroplating solution; at this time, the cooperation between the diversion hose 113 and the return pipe 112 makes the electroplating solution inside the electroplating tank 12 always flow downward, and the burr debris, dust and impurities inside the filter strip 143 are always squeezed on the inner side wall of the filter strip 143 by the extrusion force of the water source, so that the burr debris, dust and impurities inside the filter strip 143 will not be overly agitated.

[0031] Refer to Figure 1 - Figure 7 As shown in the figure, in an embodiment of the present invention, limit track strips 121 are fixedly installed on both side surfaces of the electroplating tank 12 and at the top edge position. The outer side surface of the gantry support frame 124 is movably sleeved on the inner side wall of the limit track strip 121. Threaded rods 122 are fixedly installed on both side surfaces of the electroplating tank 12 and at the bottom edge position of the limit track strip 121. A slider 123 fixedly installed on the outer side surface of the gantry support frame 124 is threadedly movably sleeved on the outer side surface of the output end of the threaded rod 122. A motor 1241 is fixedly installed on the bottom surface of the gantry support frame 124. An arc-shaped plate 1242 arranged at the middle position between the two aggregate tanks 13 is fixedly connected to the outer side surface of the output end of the motor 1241. One end of the diversion hose 113 passing through the gantry support frame 124 is located at the two side edges of the arc-shaped plate 1242. A notch is opened on the bottom surface of the aggregate tank 13. Elastic wires 131 are fixedly connected to both side edge positions at the bottom of the aggregate tank 13. A limit plate 132 arranged at the top edge position of the elastic wire 131 is movably sleeved on the inner side wall of the aggregate tank 13. Clamping support strips 133 are arranged on the inner side walls of both sides of the limit plate 132. One end of the return pipe 112 passes through the electroplating tank 12 and extends to the bottom edge position of the overlapping support plate 14. A sleeve 134 is detachably installed at the top edge position of the clamping support strip 133. A sunken limit strip 135 is arranged at the bottom edge position of the sleeve 134;

[0032] Cooperate with the condenser 111 to absorb the electroplating solution inside the return pipe 112, and then use the return pipe 112 to absorb the electroplating solution at the bottom of the electroplating tank 12. When the electroplating solution inside the return pipe 112 enters the condenser 111, cooperate with the condenser 111 to quickly cool down the remaining temperature inside the electroplating solution, and then re-inject the cooled electroplating solution into the inside of the diversion hose 113. After the low-temperature electroplating solution is mixed into the electroplating tank 12, it can quickly cool down the electroplating inside the electroplating tank 12; to avoid that after the positive and negative poles are energized, the electroplating solution inside the electroplating tank 12 will generate high temperature after being shocked. Too high temperature will cause the chemical reaction rate to increase, the deposition rate to increase, which may cause defects such as pores and cracks inside the deposition layer, reduce the crystallinity and hardness of the deposition layer, and the chemical components in the electroplating solution may decompose or deteriorate at high temperature, affecting the electroplating effect and the stability of the solution.

[0033] When the low-temperature electroplating solution enters the electroplating tank 12, cooperate with the motor 1241 on the outer surface of the gantry support frame 124 to rotate the arc-shaped plate 1242, and stir the electroplating solution inside the electroplating tank 12 repeatedly, so that the low-temperature electroplating solution and the high-temperature electroplating solution can be fully mixed together, and then quickly reduce the temperature of the electroplating solution inside the electroplating tank 12. At this time, cooperate with the threaded rod 122 to rotate, so that the slider 123 moves back and forth left and right on the outer surface of the output end of the threaded rod 122, and then drives the gantry support frame 124 on one side surface of the slider 123 to slide back and forth on the inner wall surface of the limit track bar 121, and then drives the motor 1241 to move back and forth left and right inside the electroplating tank 12, so as to fully mix the electroplating solution at different positions inside the electroplating tank 12, and then reduce the temperature of the electroplating solution.

[0034] Working principle: Place the electroplating material into the aggregate box 13, and then immerse the aggregate box 13 into the cathode electroplating bath. At the same time, cooperate with the electroplating solution inside the electroplating tank 12 to completely immerse the material inside the aggregate box 13. Connect the electroplating material to the anode of the power supply, and the cathode to the negative pole. After energization, the metal ions in the electroplating solution move to the cathode under the action of the potential difference to form a coating. At the same time, cooperate with the condenser 111 to inject the electroplating solution into the inside of the diversion hose 113, and then limit the position of one end of the diversion hose 113 through the gantry support frame 124, so that the electroplating solution discharged from the diversion hose 113 can fall from the top of the aggregate box 13. At the same time, cooperate with the condenser 111 to absorb the electroplating solution inside the return pipe 112, and then use the return pipe 112 to absorb the electroplating solution at the bottom of the electroplating tank 12, so that the electroplating solution inside the electroplating tank 12 forms a state of flowing from top to bottom. When the electroplating solution flows, it will flow quickly on the surface of the aggregate box 13. When the electroplating solution passes through the inside of the aggregate box 13, the dust impurities and burr debris on the surface of the material are cleaned up by the fluidity of the water source.

[0035] When the electroplating solution flows rapidly from top to bottom, it cooperates with the overlapping support plate 14 on the inner side wall of the electroplating tank 12 to make rapid differential contact with the flowing electroplating solution. The arc-shaped groove 144 on the inner side wall of the diversion groove plate 141 concentrates and contracts the electroplating solution at the top, so that the contracted electroplating solution passes through the arc-shaped groove 144 and enters the interior of the rectangular groove 142. At this time, the filter strip 143 on the inner side wall of the rectangular groove 142 is used to filter the rapidly flowing electroplating solution. At the same time, in cooperation with the barbs on the inner side wall at the top of the filter strip 143, it can prevent the burr debris, dust and impurities inside the filter strip 143 from flowing out again due to the electroplating solution;

[0036] At this time, the cooperation between the diversion hose 113 and the return pipe 112 makes the electroplating solution inside the electroplating tank 12 always flow downward. The extrusion pressure of the water source squeezes the burr debris, dust and impurities inside the filter strip 143 against the inner side wall of the filter strip 143 all the time, so that the burr debris, dust and impurities inside the filter strip 143 will not be overly stirred;

[0037] The condenser 111 is used to absorb the electroplating solution inside the return pipe 112. Then, the return pipe 112 absorbs the electroplating solution at the bottom of the electroplating tank 12. When the electroplating solution inside the return pipe 112 enters the condenser 111, the condenser 111 quickly cools down the remaining temperature inside the electroplating solution. Then, the cooled electroplating solution is re-injected into the interior of the diversion hose 113. After the low-temperature electroplating solution is mixed into the electroplating tank 12, it can quickly cool down the electroplating inside the electroplating tank 12;

[0038] When the low-temperature electroplating solution enters the electroplating tank 12, the motor 1241 on the outer surface of the gantry support frame 124 is used to rotate the arc-shaped plate 1242, and the electroplating solution inside the electroplating tank 12 is repeatedly stirred, so that the low-temperature electroplating solution and the high-temperature electroplating solution can be fully mixed together, and then quickly reduce the temperature of the electroplating solution inside the electroplating tank 12. At this time, the threaded rod 122 is rotated, so that the slider 123 moves back and forth left and right on the outer surface of the output end of the threaded rod 122. Then, the gantry support frame 124 on one side surface of the slider 123 slides back and forth on the inner side wall of the limit track strip 121, and then drives the motor 1241 to move back and forth left and right inside the electroplating tank 12, so as to fully mix the electroplating solution at different positions inside the electroplating tank 12, and then reduce the temperature of the electroplating solution.

[0039] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. The obvious changes or modifications derived therefrom still fall within the protection scope of this utility model.
