Description

[0002] In the process of nickel electrowinning in the sulfate system, the cathode starting sheet of the electrowinning tank must be made first.

DETAILED DESCRIPTION

[0040] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] Reference Figure 1-Figure 4 : A nickel electrodeposition starting sheet rapid processing device, comprising a feeding mechanism 3 for conveying nickel foil and copper foil;

[0042] The processing device also includes a laser cutting mechanism 4, a welding mechanism 5 and a workbench 6; the welding mechanism 5 includes an ultrasonic welding gun 51 and a belt pressing assembly 52. ​​In the working state, the feeding mechanism 3 conveys the nickel foil to the laser cutting mechanism 4, the laser cutting mechanism 4 cuts the nickel foil to form a square nickel sheet, the feeding mechanism 3 conveys the copper foil to the welding mechanism 5, and then the square nickel sheet is moved to the pre-printed plastic bottom frame and above the copper foil head by a manipulator, the welding mechanism 5 welds the copper foil head to the pole ear 81 of the square nickel sheet, the laser cutting mechanism 4 cuts the copper foil strip, and the other end of the copper foil is rolled and pressed on the pole ear 81 by the belt pressing assembly 52 of the workbench 6, and then the other end of the copper foil is welded to the pole ear 81 by the welding mechanism 5, and then the plastic face frame is printed by the additive printing mechanism 7.

[0043] As the first embodiment of the present invention, the present invention realizes the function of efficiently processing the nickel electrolytic starting plate through the feeding mechanism 3, the laser cutting mechanism 4, the welding mechanism 5 and the workbench 6, and forms a frame for supporting the nickel electrolytic starting plate through 3D printing to stably support the starting plate. It not only fixes the nickel foil, but also makes the produced starting plate easy to enter the groove, and will not scratch the diaphragm bag. The nickel foil used in this embodiment is a finished nickel foil coil 1 produced by calendering, with a purity of 99.95%, a thickness of 0.1mm and a width of 1000mm; the outer dimensions of the starting plate used in this embodiment are 880+40mm, and 880mm is the length of the nickel electrolytic plate in the next process; 40mm is the width of the two side frames, and the width is 900+40mm, 900mm is the width of the nickel electrolytic plate in the next process, and 40mm is the width of the two side frames. The outer dimensions of the square nickel foil 8 are (880+20) mm×(900+20) mm, with two pole ears 81 on one side of the 900 mm side, and the size of 81 is 300 mm×100 mm. Six circular holes with a diameter of 5 mm are punched by laser at the designated positions on each side of the cut square nickel foil, and the outer periphery of the holes is 3 mm away from the edge of the square nickel foil. The manipulator is a handling robot with positioning and suction cups. After the starting electrode of this embodiment is used for the production of electrolytic nickel plates, the nickel-free parts of the frame and the copper sling are separated from the finished nickel plates by laser cutting, and the copper sling is recycled as waste copper. The small amount of nickel foil and copper in the frame is heated with dilute sulfuric acid and hydrogen peroxide at 50-65°C to dissolve the metal, and returned to the nickel electrolyte production line for recycling. The waste plastics can be reused after washing, drying and granulation.

[0044] The traditional starting electrode is produced by using a seed plate as a cathode in the starting electrode electrolytic cell. Since nickel can be deposited on all sides of the seed plate during electrolytic deposition, it is necessary to install a plastic clamping strip on the seed plate to prevent the two sides from growing together. When the electrolytic nickel reaches 0.6-1.2 mm thick, it takes about 48-56 hours. The seed plate is hoisted out, the clamping strip is removed, and the nickel sheets on both sides of the seed plate are peeled off with a stripping machine. After peeling, it is cut, pressed, riveted and welded with a conductive sling 82, and rinsed. Among them, the peeling process is the most critical and affects the yield. In order to improve the production efficiency of the starting electrode, the present invention directly uses nickel foil commercial coils as raw materials, omitting the processes of seed plate production, starting electrode electrolytic deposition, and peeling. The reason for using commercial nickel foil is that nickel foil with a thickness of more than 0.01 mm, a certain width, and any length can be quickly mass-produced by physical calendering or roller electrolytic deposition, and its surface is regular and smooth. After cold rolling, it has high hardness and strength, which lays the foundation for the automated production of starting electrodes. However, nickel foil that is too thick cannot be used, otherwise the amount of nickel used will increase, which is not economically cost-effective. If thin nickel foil is used, its strength and rigidity are not enough, and it is not easy to make an ideal flat starting electrode sheet, and it is also not easy to put the starting electrode sheet into the groove. For this reason, the present invention adopts the process of adding a frame to the nickel foil, which not only fixes the nickel foil but also makes it easy to put the starting electrode sheet into the groove without scratching the diaphragm bag. This is just like making a frame for a soft painting. A bottom frame groove is provided on the workbench 6. The frame of this embodiment is welded by a bottom frame and a surface frame. Both the bottom frame and the surface frame are prefabricated injection molded parts, and the thermal deformation temperature of the material is >100°C.

[0045] In the working state, the nickel foil is conveyed by the feeding mechanism 3, and then the bottom frame is moved to the bottom frame groove on the workbench 6 by the manipulator for standby use, and then the copper foil is conveyed by the feeding mechanism 3. The nickel foil first arrives at the laser cutting mechanism 4 for cutting processing. The laser cutting mechanism 4 cuts the nickel foil to form a square nickel sheet, and then the square nickel sheet is conveyed to the bottom frame by the manipulator. The pole ear 81 of the nickel foil sheet 8 is just pressed on the copper foil strip head, and the two are welded by the welding mechanism 5. The copper foil strip is cut by the laser cutting mechanism 4, and the other end of the copper foil is rolled and pressed on the pole ear 81 by the workbench 6 belt pressing assembly 52, and then the other end of the copper foil is welded to the pole ear 81 by the welding mechanism 5. The face frame is moved to the bottom frame by the manipulator, and then the face frame and the bottom frame are welded. Then the conductive rod 83 is inserted into the starting pole piece by the manipulator, and the starting pole piece is hoisted to the electrolytic cell.

[0046] Reference Figure 1 , Figure 5 , Figure 8 and Fig. 9 : An additive printing mechanism 7 is provided on the workbench 6, and the additive printing mechanism 7 includes a machine head 71 and a vacuum temporary storage tank 72; the machine head 71 is arranged on the workbench 6; an electric heater for heating the raw material is provided in the machine head 71; the vacuum temporary storage tank 72 is connected to the machine head 71 through a pipeline.

[0047] As a second embodiment of the present invention, the present invention realizes the function of printing and generating a bottom frame and a face frame through a machine head 71 and a vacuum temporary storage tank 72, and directly prints the bottom frame and the face frame with molten plastic on the production line, without prefabricating the bottom frame and the face frame, eliminating the steps of transporting prefabricated parts, welding and bonding, improving processing efficiency, and reducing the demand for parts inventory. The plastic powder or plastic granules are stored in the vacuum temporary storage tank 72, and then the raw materials are heated by the electric heater in the machine head 71 to ensure the stable operation of the frame printing work. A preheating section and a melting section are formed in the machine head 71 by the electric heater, and the heating temperature of the preheating section is 20 to 50°C lower than the softening point temperature of the selected thermoplastic plastic, and the heating temperature of the melting section is 20 to 50°C higher than the softening point temperature of the selected thermoplastic plastic, preferably 30°C; the bottom frame and the face frame are preferably made of nylon, and the melting temperature range is 180 to 260°C.

[0048] In the working state, the nickel foil is transported by the feeding mechanism 3, and the nickel foil first reaches the laser cutting mechanism 4 for cutting processing, and the laser cutting mechanism 4 cuts the nickel foil to form a square nickel sheet. At this time, the square bottom frame is printed out by the additive printing mechanism 7 for standby, and the feeding mechanism 3 transports the copper foil to the welding mechanism 5 for standby. Then the square nickel sheet is transported to the square bottom frame and the copper foil strip head at the additive printing mechanism 7 by the manipulator, and the copper foil strip head is welded to the square nickel sheet pole ear 81. The copper foil strip is cut by the laser cutting mechanism 4, and the other end of the copper foil is rolled and pressed on the pole ear 81 by the workbench 6 belt pressing assembly 52, and then the other end of the copper foil is welded on the pole ear 81 by the welding mechanism 5 to form a conductive sling 82. Then the thermoplastic plastic is printed on the four sides of the nickel sheet by the additive printing mechanism 7 to form a square plastic frame, that is, a nickel electroplating starting plate is made. When performing 3D printing of the bottom frame and the border, raw materials are provided through the vacuum temporary storage tank 72, and the raw materials are heated after entering the head 71. The raw materials are preheated in the preheating section and further heated in the melting section, and then the border and the bottom frame are printed.

After the plastic powder or granular material is heated and melted by the electric heater in the head 71, the push screw is driven to rotate by the drive motor 74, and the push screw pushes the material to move toward the end of the head 71, and then the molten material is squeezed out to print the frame.
