Description

Technical Field

[0001] The invention relates to the technical field of electroplating, in particular to an automatic feeding device for an electroplating tank. Background Art

[0002] During the electroplating process, the electroplating solution in the electroplating tank will be gradually consumed due to chemical reactions and electroplating operations, resulting in a decrease in the concentration of the electroplating solution, thereby affecting the quality of electroplating. Therefore, it is necessary to frequently add materials to the electroplating tank. The Chinese patent application with application number 202220481559.0 discloses "an electroplating tank that is easy to add materials, which solves the problem that the amount of materials added to the electroplating tank is difficult to control. The electroplating tank includes a plurality of main tank bodies, and a feeding tank is arranged between the main tank bodies. A circulating feeding component is connected between the feeding tank and the main tank bodies. A stirring component connected to the circulating feeding component is respectively arranged inside the main tank body and the feeding tank, and the circulating feeding component is equipped with a filtering component. The utility model has the advantages of convenient feeding and stable structure. "; This technical solution only solves the problem that it is difficult to control the amount of material added to the electroplating tank. When the plating solution is added to the electroplating tank manually, it is not only difficult to control the amount of material added, but also the manual addition is labor-intensive and has certain safety hazards. In addition, in the electroplating process, the electroplating solution is the core working medium, which is used to deposit a metal layer on the metal surface. However, a variety of electroplating waste residues will be generated during the electroplating process. These waste residues enter the electroplating solution and directly affect the performance of the electroplating solution and the quality of electroplating. Existing equipment often finds it difficult to process the aged electroplating solution while automatically adding materials. When the electroplating waste residues accumulate too much, the conductivity of the electroplating solution will be reduced, resulting in increased electroplating energy consumption and low electroplating efficiency.

[0019] Working principle: When the present invention is in use, new electroplating liquid is filled into the liquid storage tank 601 through the liquid inlet pipe 602, so that the liquid storage tank 601 is kept with new electroplating liquid. When the tank body 2 needs to add electroplating liquid, the movable rotating shaft 706 is first pushed by the electric push rod 713, so that the two second bevel gears 707 are not meshed with the first bevel gear 703, and then the first electric valve 608 is closed to close the liquid extraction pipe 606, and the second electric valve 609 is opened to make the air pipe 607 conductive. At this time, the motor 605 is started to drive the liquid adding pump 604. When the liquid adding pump 604 works, air is drawn through the air pipe 607 and sprayed into the tank body 2 through the nozzle 611 on the liquid adding pipe 610. The electroplating liquid in the tank body 2 is stirred by the sprayed air, so that the electroplating waste residue generated during the electroplating process and deposited at the bottom of the tank body 2 is stirred up; The movable rotating shaft 706 is pushed by the electric push rod 713, so that a second bevel gear 707 is meshed with the first bevel gear 703, and the worm 711 is driven to rotate by the second belt 712, and the worm 711 drives the worm wheel 710 to rotate, so that the first rotating shaft 704 rotates following the worm wheel 710, and the shaft key 708 is driven to rotate by the key slot 709, so that the movable rotating shaft 706 rotates following the shaft key 708, and at this time, the two second bevel gears 707 both rotate simultaneously following the movable rotating shaft 706; After the air is sprayed in, the second bevel gear 707 meshes with the first bevel gear 703, driving the first bevel gear 703 to rotate, and then the fourth gear 702 is driven to rotate through the first bevel gear 703, and the third gear 701 is driven to rotate through the fourth gear 702. When the third gear 701 rotates, the screw sleeve 407 is driven to rotate. At this time, the lifting plate 404 is driven to rise through the threaded rod 405. When the lifting plate 404 rises to the top of the connecting frame 401, when the lifting plate 404 continues to rise, the connecting frame 401 is driven to rise at the same time, and the lifting frame 307 is driven to rise through the connecting frame 401. At this time, the spring rod 402 is inserted into the top of the lifting frame 307, so that the reset spring 403 is compressed, and the rising lifting frame 307 drives the cover plate 302 to rotate through the connecting arm 308, so that the liquid outlet 301 is opened. At this time, the old liquid in the tank body 2 enters the recovery box 303 through the liquid outlet 301 and is filtered through the filter layer 304. According to actual production needs, the electric push rod 713 is used to pull back the movable rotating shaft 706, so that the other second bevel gear 707 is meshed with the first bevel gear 703, so that the screw sleeve 407 is reversed, and at this time, the lifting plate 404 is driven to descend by the threaded rod 405. When the lifting plate 404 descends, the elastic force of the reset spring 403 makes the connecting frame 401 descend along with the lifting plate 404, so that the lifting frame 307 follows the connecting frame 401 to descend, and at this time, the cover plate 302 is driven to rotate by the connecting arm 308, so that the liquid outlet 301 is closed, and at this time, the descending lifting plate 404 makes the volume of the cavity formed by the recovery box 303, the filter layer 304, the limit frame 306 and the lifting plate 404 continuously decrease, so that the old liquid in the cavity is filtered faster, and the old liquid after filtering enters the old liquid tank 305; When the shaft key 708 rotates with the movable shaft 706, the second shaft 705 is driven to rotate through the key slot 709. When the second shaft 705 rotates, the screw shaft 603 is driven to rotate through the third belt 715, so that the new liquid in the liquid storage tank 601 and the old liquid in the old liquid tank 305 are evenly mixed, so that the concentration of the new liquid added to the tank body 2 during automatic feeding reaches the required concentration; During the process of the lifting plate 404 descending, the first electric valve 608 is opened to conduct the liquid extraction pipe 606, and the second electric valve 609 is closed to seal the air pipe 607. At this time, the liquid adding pump 604 extracts the new liquid mixed evenly in the liquid storage tank 601 through the liquid extraction pipe 606, and discharges it into the tank body 2 through the nozzle 611 on the liquid adding pipe 610, so as to realize automatic feeding; When the screw sleeve 407 rotates, the first belt 505 drives the stirring shaft 501 to rotate, so that the first gear 502 rotates along with the stirring shaft 501 , and the first gear 502 drives the second gear 503 to rotate, so that the stirring blade 504 rotates along with the second gear 503 , so that the new liquid added to the tank body 2 and the old liquid in the tank body 2 are evenly mixed under the stirring of the stirring shaft 501 and the stirring blade 504 .
