The existing technology is to make copper and aluminum materials into corresponding styles, connect the two ends by friction welding and form the terminal block by cutting. Copper and aluminum are very easy to electrochemically oxidize when encountering humid air due to their different activities when electricity is applied. In addition, the terminal block is often prone to heat up and break under stress due to the different resistance and thermal melting point around the welding surface, which seriously affects the distribution and use of electricity.

The surface of the copper-aluminum terminal block is plated with a nickel layer and a copper layer, which improves the corrosion resistance of the copper-aluminum terminal block.

[0015] A method for processing a corrosion-resistant terminal block comprises the following steps: S1: Put the unformed terminal aluminum bar into the discharge trough, and the output shaft of the first motor rotates clockwise to move the T-shaped front stamping die backwards. The backward movement of the T-shaped front stamping die drives the feeding block to move synchronously, so that the aluminum bar enters the stamping positioning block. The aluminum bar is squeezed by the T-shaped front stamping die and the stamping rear die. At this time, one end of the aluminum bar is stamped into a cylindrical shape by the T-shaped front stamping die, thereby realizing the preliminary processing of the terminal aluminum bar; S2: The output shaft of the first motor rotates counterclockwise, causing the stamping upper die to move downward, and the stamping rear die to move backward. The stamping upper die contacts and squeezes the aluminum rod, so that the other end of the aluminum rod becomes flat under the joint stamping of the stamping upper die and the stamping lower die, thereby further processing the aluminum rod of the terminal; S3: Repeat step S1. When the new aluminum rod slides in the stamping positioning block, the stamped aluminum rod is pushed onto the conveyor belt.

The aluminum rod rotates due to its own center of gravity, so that the angle of the aluminum rod is adjusted. S4: Start the special-shaped driving guide rail, which makes the conductive claw and the aluminum rod on the hanging rod move synchronously, and the first friction rod contacts the second friction roller to shrink the conductive claw, and then the first friction rod separates from the second friction roller, so that the conductive claw clamps the aluminum rod; S5: Start the second motor to make the electrolyte in the compression block squeeze conduit flow, start the external DC power supply, and the aluminum rod slides into the electrolyte under the drive of the special-shaped driving guide rail. The external DC power supply flows from the consumable plate to the aluminum rod, so that the surface of the aluminum rod is plated with a metal film. When the aluminum rod is around the conduit, the electrolyte flows to remove the bubbles on the surface of the aluminum rod and replenish the electrolyte concentration. After acid immersion, nickel plating, acid copper plating, nickel plating, alkaline copper plating, and cleaning with cleaning solution, the aluminum rod becomes a terminal, thereby realizing the processing of corrosion-resistant terminal; S6: The second friction rod contacts the second friction roller, causing the conductive claw to shrink, and the connecting terminal is separated from the conductive claw.

[0016] Compared with the prior art, the present invention has the following advantages: 1. The present invention starts the first motor so that when the stamping upper die moves upward, the stamping rear die moves forward, and the T-shaped stamping front die moves backward. When the stamping upper die moves downward, the stamping rear die moves backward, and the T-shaped stamping front die moves forward, so that the terminal stamping processing actions are performed alternately. The T-shaped stamping front die moves backward and the first spring pushes the feeding block to move synchronously, pushing the aluminum bar into the unloading guide rail and into the stamping positioning block along the unloading guide rail, so that the aluminum bar is stamped by the T-shaped stamping front die and the stamping rear die, thereby realizing automatic feeding and stamping of the aluminum bar. The pusher claw moves during the stamping process to automatically clean up the excess material, effectively improving the efficiency of aluminum bar stamping.

[0017] 2. The present invention squeezes the electrolyte in the conduit through the pressing block, and sprays the electrolyte from the extended long end of the conduit, so that the bubbles on the outer surface of the aluminum rod are blown away, preventing electroplating depressions from appearing on the surface of the aluminum rod, thereby improving the processing quality of the electroplating of the terminal.

[0018] 3. The present invention extrude the C-shaped frame through the second support tube so that the catheter extends into the cylindrical end of the aluminum rod. The electrolyte sprayed from the catheter can blow away the bubbles on the inner surface of the aluminum rod, preventing the accumulation of bubbles in the cylindrical end of the aluminum rod, resulting in the inner surface of the cylindrical end of the aluminum rod being unable to contact the electrolyte and causing electroplating defects, thereby improving the processing quality of the electroplating of the terminal.

[0031] A method for processing a corrosion-resistant terminal block, characterized in that it comprises the following steps: S1: Put the unformed terminal aluminum bar into the discharge trough 211, and the output shaft of the first motor 214 rotates clockwise to move the T-shaped front stamping die 208 backward. The T-shaped front stamping die 208 moves backward to drive the feeding block 210 to move synchronously, so that the aluminum bar enters the stamping positioning block 212, and the aluminum bar is squeezed by the T-shaped front stamping die 208 and the stamping rear die 205. At this time, one end of the aluminum bar is stamped into a cylindrical shape by the T-shaped front stamping die 208, thereby realizing the preliminary processing of the terminal aluminum bar; S2: The output shaft of the first motor 214 rotates counterclockwise, so that the stamping upper die 203 moves downward, and the stamping rear die 205 moves backward. The stamping upper die 203 contacts and squeezes the aluminum rod, so that the other end of the aluminum rod becomes flat under the joint stamping of the stamping upper die 203 and the stamping lower die 2031, thereby further processing the terminal aluminum rod; S3: Repeat step S1. When the new aluminum rod slides in the stamping positioning block 212, the stamped aluminum rod is pushed onto the conveyor belt 301. The aluminum rod is limited by the edge of the second adjustment block 303 and rotates, so that the cylindrical end of the aluminum rod faces the hanging rod 306. If the sliding distance of the flat end of the aluminum rod is too large, the aluminum rod is limited by the edge of the first adjustment block (302) and rotates. Finally, it is hung on the hanging rod 306. The aluminum rod rotates due to its own center of gravity, so that the angle of the aluminum rod is adjusted. S4: Start the special-shaped driving guide rail 602, which makes the conductive claw 611 move synchronously with the aluminum rod on the hanging rod 306, and the first friction rod 7 contacts the second friction roller 606, so that the conductive claw 611 contracts, and then the first friction rod 7 is separated from the second friction roller 606, so that the conductive claw 611 clamps the aluminum rod; S5: Start the second motor 502, so that the pressing block 511 squeezes the electrolyte in the conduit 512 to flow, start the external DC power supply, and the aluminum rod slides into the electrolyte under the drive of the special-shaped driving guide rail 602. The external DC power supply flows from the consumable plate 5011 to the aluminum rod, so that the surface of the aluminum rod is plated with a metal film. When the aluminum rod is around the conduit 512, the electrolyte flows to remove the bubbles on the surface of the aluminum rod and replenish the electrolyte concentration. After acid immersion, nickel plating, acid copper plating, nickel plating, alkaline copper plating, and cleaning with cleaning solution, the aluminum rod becomes a terminal, and the processing of corrosion-resistant terminal is realized; S6 : the second friction rod 8 contacts the second friction roller 606 , causing the conductive claw 611 to contract, and the connection terminal is separated from the conductive claw 611 .

At this time, the stamping upper die 203 and the stamping lower die 2031 are in contact with each other. By starting the first motor 214, the output shaft of the first motor 214 rotates clockwise and drives the second screw rod 213 to rotate synchronously, so that the second screw rod 213 drives the stamping upper die 203 to move upward along the light rod and disengage from the stamping lower die 2031. During the upward movement of the stamping upper die 203, the connecting rod 204 drives the stamping rear die 205 to move forward. The forward movement of the stamping rear die 205 causes the first screw rod 207 to rotate. The rotation of the first screw rod 207 causes the T-shaped stamping front die 208 to move backward along the third support frame 209, so that the T-shaped stamping front die 208 pushes the first spring and the feeding block 210 to move backward. Since the thread pitch at the front end of the first screw rod 207 is longer than the thread pitch at the rear end, and the two screw rods are The rotation direction of the distance is opposite, so that the feeding block 210 first pushes the aluminum rod at the bottom of the discharge trough 211 into the unloading guide rail of the third support frame 209, and the aluminum rod enters the stamping positioning block 212 along the unloading guide rail of the third support frame 209. At this time, the T-shaped stamping front die 208 continues to push the first spring and the feeding block 210 to move backward until the feeding block 210 contacts the stamping positioning block 212 to block the movement of the feeding block 210, so that the T-shaped stamping front die 208 compresses the first spring and penetrates the feeding block 210 to contact the aluminum rod, and at the same time, the stamping rear die 205 moves forward to contact the aluminum rod. At this time, the T-shaped stamping front die 208 continues to move backward, and the stamping rear die 205 continues to move forward, so that the T-shaped stamping front die 208 and the stamping rear die 205 jointly extrude the aluminum rod. At this time, one end of the aluminum rod is stamped into a cylindrical shape by the T-shaped stamping front die 208 and the preliminary processing of the aluminum rod terminal is realized.

[0033] When the stamping of one end of the aluminum rod is completed, the T-shaped front stamping die 208 is located in the cylindrical end of the aluminum rod, and the stamping rear die 205 is in contact with the stamping positioning block 212. At this time, the output shaft of the first motor 214 is controlled to rotate counterclockwise, thereby driving the stamping upper die 203 to move downward along the light rod through the second screw rod 213. The stamping upper die 203 moves downward and drives the stamping rear die 205 to move backward and disengage from the stamping positioning block 212 through the connecting rod 204. At the same time, the T-shaped front stamping die 208 moves forward. The aluminum bar is separated from the punched aluminum bar. At this time, the damping of the inner wall of the punch positioning block 212 limits the movement of the aluminum bar. The damping of the inner wall of the punch positioning block 212 realizes the positioning of the aluminum bar after punching, which effectively prevents the friction force generated on the aluminum bar when the T-shaped punching front die 208 and the punching rear die 205 move away from each other and reset to prevent the position of the aluminum bar from changing, thereby avoiding the misalignment problem during the next punching. At this time, the punching upper die 203 continues to move downward and contacts the punching lower die 2031 to punch the aluminum bar again, and the aluminum bar is punched again. One end is stamped into a flat shape. During the process of the other end of the aluminum rod being flattened by the stamping upper die 203, the excess material at the other end of the aluminum rod will spread around along the stamping lower die 2031 to generate excess material, and will be squeezed by the bottom edge of the stamping upper die 203, so that a large shear stress is generated at the position where the top of the other end of the aluminum rod contacts the bottom edge of the stamping upper die 203. Under the action of the shear stress, the excess material breaks along the bottom edge of the stamping upper die 203 and separates from the other end of the aluminum rod. At this time, the shape of the aluminum rod terminal is processed. When the feeding block 210 is completed, the first spring is released and drives the feeding block 210 to move forward and reset. When the feeding block 210 moves along the discharge trough 211, the inclined surface on the top of the front side of the feeding block 210 pushes the new aluminum rod in the discharge trough 211 upward, so that the aluminum rod in the discharge trough 211 is located on the upper side of the feeding block 210. When the feeding block 210 is reset, it will be separated from the discharge trough 211, so that the new aluminum rod falls into the bottom of the discharge trough 211, realizing the intermittent feeding function. Repeat the above steps and realize the automated processing of the aluminum rod terminals.

[0034] During the stamping process of the aluminum rod, the residual material is sheared and separated from the aluminum rod by the stamping upper die 203, and then falls on the second base 201 under the action of gravity. The above-mentioned processing steps of the aluminum rod terminal are repeated to make the output shaft of the first motor 214 rotate clockwise to drive the stamping rear die 205 to move forward. The stamping rear die 205 moves forward and drives the finger 216 to move synchronously through the convex shell 215. During the forward movement of the finger 216, the bottom of the finger 216 will contact the residual material, so that the finger 216 rotates counterclockwise inside the convex shell 215, and the bottom of the finger 216 slides to the top of the residual material along the contact position with the residual material. During the rotation of the finger 216, the first spring will accumulate force, and then the finger 216 will continue to follow the convex shell 215 to move forward, so that the bottom of the finger 216 slides along the top of the residual material until the bottom of the finger 216 is separated from the residual material. At this time, the first spring is restored and drives the finger The claw 216 rotates to reset, and then the convex shell 215 continues to slide forward until the stamping rear die 205 moves forward to complete a preliminary processing. At this time, the convex shell 215 slides into the rectangular groove on the rear side of the stamping positioning block 212; thereafter, the output shaft of the first motor 214 rotates counterclockwise to drive the stamping rear die 205 to move backward, so that the stamping rear die 205 drives the pusher claw 216 to move synchronously through the convex shell 215, so that the bottom of the pusher claw 216 contacts the residual material again during the backward movement. Due to the limitation of the pusher claw 216 by the front side of the convex shell 215, the pusher claw 216 pushes the residual material to move synchronously along the second base 201 when moving backward, until the pusher claw 216 pushes the residual material down from the top rear end of the base 201, thereby realizing the cleaning of the residual material under the stamping upper die 203, avoiding the accumulation of residual material under the stamping upper die 203 affecting the stamping process of the stamping upper die 203, and further improving the processing efficiency of the aluminum bar.

[0035] In the process of repeating the above-mentioned processing steps of the aluminum rod terminal, the T-shaped stamping front die 208 moves backward, which pushes the first spring and the feed block 210 to move backward. The feed block 210 pushes the other aluminum rod at the bottom of the discharge trough 211 into the unloading guide rail of the third support frame 209. The other aluminum rod enters the stamping positioning block 212 along the unloading guide rail of the third support frame 209, so that the rear end of the other aluminum rod contacts the cylindrical end of the aluminum rod in the stamping positioning block 212, and pushes the aluminum rod in the stamping positioning block 212 to move backward, and the aluminum rod in the stamping positioning block 212 is separated from the stamping positioning block. Block 212 falls on the stamping lower die 2031. As the stamped aluminum rod continues to move backward, its center of gravity will leave the top of the stamping lower die 2031, causing the stamped aluminum rod to fall along the rear end edge of the top of the stamping lower die 2031 and enter the unloading trough of the second base 201. Since the center of gravity of the stamped aluminum rod is biased toward the flat end, the flat end of the aluminum rod is always facing backward and downward when it falls. Finally, the aluminum rod falls on the conveyor belt 301 with the flat end facing backward, thereby realizing automatic unloading of the stamping processing mechanism 2 and further improving the processing efficiency of the terminal block.

[0036] When the aluminum rod falls on the conveyor belt 301, the conveyor belt 301 is started, so that the conveyor belt 301 drives the aluminum rod to move to the right. In the process of the aluminum rod moving to the right, since the flat end of the aluminum rod is at the rear, its flat end will first contact the left front edge of the second steering block 303, causing the flat end of the aluminum rod to be limited by the second steering block 303. Driven by the conveyor belt 301, the contact point between the flat end of the aluminum rod and the left front edge of the second steering block 303 rotates counterclockwise, causing the cylindrical end of the aluminum rod to continue to move to the right. In the process of the cylindrical end of the aluminum rod moving to the right, the flat end of the aluminum rod is squeezed and limited by the left front edge of the second steering block 303, causing the flat end of the aluminum rod to be The aluminum rod 306 is moved to the left, thereby realizing that the cylindrical end of the aluminum rod is facing the driving shaft 304; thereafter, the aluminum rod continues to move to the right under the drive of the conveyor belt 301, so that the aluminum rod is separated from the second adjustment block 303. If the rotation angle of the aluminum rod is too large, the flat end of the aluminum rod will also contact the rear left edge of the first adjustment block 302. As the aluminum rod continues to move to the right, the rear left edge of the first adjustment block 302 squeezes the flat end of the aluminum rod, thereby causing the aluminum rod to rotate. The cylindrical end of the aluminum rod will be more accurately oriented to the driving shaft 304, making it easier for the hanging rod 306 to slide into the cylindrical end of the aluminum rod. After the rotation of the cylindrical end of the aluminum rod is completed, the aluminum rod continues to move to the right, so that the aluminum rod is rotated and separated from the first adjustment block 302.

[0037] When the conveyor belt 301 is running, it will also drive the drive shaft 304 to rotate counterclockwise through the belt transmission group 305. The rotation of the drive shaft 304 will drive the hanging rod 306 to rotate synchronously. When the hanging rod 306 rotates close to the conveyor belt 301, the aluminum rod is also moving to the right, so that one end of the hanging rod 306 will gradually extend into the cylindrical end of the aluminum rod and contact the inner wall of the cylindrical end of the aluminum rod. As the hanging rod 306 rotates, the hanging rod 306 will drive the aluminum rod to rotate counterclockwise on the conveyor belt 301. It is worth noting that since the drive shaft 304 is tilted, the hanging rod 306 has an inclination angle, and the diameter of the aluminum rod cylinder is larger than the diameter of the hanging rod 306. When the cylindrical end of the aluminum rod contacts the hanging rod 306, the hanging rod 306 will be stuck in the cylindrical end of the aluminum rod. When the aluminum rod is driven by the hanging rod 306 to rotate and one end of the hanging rod 306 faces backward, the conveyor belt 301 is stopped to facilitate the subsequent clamping of the aluminum rod.

[0038] When the hanging rod 306 rotates, the special-shaped driving guide rail 602 is started, and the special-shaped driving guide rail 602 drives the special-shaped transmission belt 603 to run, so that the special-shaped transmission belt 603 drives the two adjacent sliding frames 612 to move synchronously close to the hanging rod 306, and the two sliding frames 612 slide and jointly drive the sixth support frame 604 to move synchronously. It is worth noting that the two sliding frames 612 will rotate left and right and up and down along the special-shaped transmission belt 603 when approaching the hanging rod 306. The two sliding frames 612 drive the sixth support frame 604 to rotate through the rotating frame 613, and the elastic potential energy of the third spring is stored and released. The sixth support frame 604 drives the first slide plate 608 to slide through the second support tube 607, thereby driving the conductive claw 611 to move synchronously. The conductive claw 611 will gradually approach the flat end of the aluminum rod on the hanging rod 306 during the movement. It is worth noting that when the conductive claw 611 and the flat end of the aluminum rod on the hanging rod 306 are at the same position along the front-to-back direction, the conveyor belt 301 is started again. The conveyor belt 301 drives the hanging rod 306 to drive the aluminum rod to rotate, so that the conductive claw 611 and the flat end of the aluminum rod on the hanging rod 306 always keep the position synchronous, and the conductive claw 611 can be inserted into the round hole of the flat end of the aluminum rod in the process of approaching the flat end of the aluminum rod. In the process of the conductive claw 611 moving close to the flat end of the aluminum rod, the sixth support frame 604 moves through the second bevel gear set 605 to drive the second friction roller 606 to move forward, so that the bottom of the cylindrical outer wall of the second friction roller 606 contacts the first friction rod 7 to roll, and the second friction roller 606 rotates through the second bevel gear set 605 to drive the driving cylinder 609 to rotate and make the second spring store elastic potential energy, and the driving cylinder 609 rotates through the several second slide grooves of the second slide groove plate 610 to push the corresponding conductive claw 611, so that the several conductive claws 611 slide close to each other in the several first slide grooves of the first slide groove plate 608, so that the several conductive claws 611 are convenient for inserting into the round hole of the flat end of the aluminum rod, and the conductive claw 611 is improved to insert into the round hole of the flat end of the aluminum rod;When the sixth support frame 604 is located directly above the driving shaft 304, the conductive claw 611 has been inserted into the circular hole at the flat end of the aluminum rod, and the special-shaped transmission belt 603 continues to drive the two sliding frames 612 to move, so that the two sliding frames 612 drive the sixth support frame 604 to move through the rotating frame 613, and the sixth support frame 604 moves through the second bevel gear set 605 to drive the second friction roller 606 to continue to move, so that the second friction roller 606 is separated from the first friction rod 7, and the second friction roller 606 loses the friction limit, so that the second clockwork spring releases elastic potential energy to restore its shape, and the second clockwork spring restores its shape and drives the second friction roller 606 to rotate and reset through the second bevel gear set 605, and drives the second slide plate 610 to rotate and reset through the driving cylinder 609, driving The cylinder 609 rotates through the second slots of the second slot plate 610 to push the corresponding conductive claws 611, so that the conductive claws 611 slide away from each other in the first slots of the first slot plate 608, and squeeze the inner wall of the circular hole at the flat end of the aluminum rod through its own edges, so that the aluminum rod is clamped by the conductive claws 611, thereby achieving the clamping of the aluminum rod by the conductive claws 611. As the sixth support frame 604 continues to move along the special-shaped driving guide rail 602 and the hanging rod 306 continues to rotate, the conductive claws 611 will drive the aluminum rod to gradually move away from the hanging rod 306, so that the cylindrical end of the aluminum rod gradually separates from the hanging rod 306. After the cylindrical end of the aluminum rod completely separates from the hanging rod 306, the conductive claws 611 will drive the aluminum rod to move along the special-shaped driving guide rail 602 toward the electroplating pool 501. ;

[0039] When the aluminum rod approaches the electroplating tank 501, the second motor 502 is started, and the output shaft of the second motor 502 rotates clockwise, and drives the friction belt 503 to drive the first friction roller 506 to rotate clockwise through the friction shaft. The first friction roller 506 rotates and drives the driving rod 510 to rotate counterclockwise through the first bevel gear set 505. The driving rod 510 rotates to rotate the pressing block 511, so that the cylindrical end of the pressing block 511 changes the position of the extrusion conduit 512 in the counterclockwise direction, and the internal capacity of the protruding short end of the conduit 512 increases, and a vacuum appears inside the conduit 512, so that the protruding short end of the conduit 512 absorbs electrolyte to the electroplating tank 501, and the plating solution enters the interior of the conduit 512 from the protruding short end of the conduit 512. At the same time, the internal capacity of the protruding long end of the conduit 512 is reduced, so that the electrolyte inside the conduit 512 is squeezed by the cylindrical end of the pressing block 511, so that the electrolyte is ejected from the protruding long end of the conduit 512, and the electrolyte in the electroplating tank 501 flows. Figure 6As shown, during the movement of the conductive claw 611 along the special-shaped driving guide rail 602, the aluminum rod will be moved downward and fall into the electrolyte of the frontmost electroplating tank 501. Since the electrolyte in the rearmost electroplating tank 501 is a pickling solution, the oxides and impurities on the surface of the aluminum rod can be corroded and cleaned by the pickling solution, thereby ensuring the cleanliness of the surface of the aluminum rod. It is worth noting that after the pickling solution on the surface of the aluminum rod cleans the aluminum rod, the concentration of the pickling solution around the aluminum rod will become lower, thereby reducing the efficiency of the pickling solution in cleaning the aluminum rod. However, since the pickling solution continues to flow in the electroplating tank 501, the concentration of the pickling solution around the aluminum rod will decrease. The concentration of the pickling solution is kept stable, thereby improving the efficiency of cleaning the aluminum rod with the pickling solution. When the conductive claw 611 drives the aluminum rod to continue to move along the special-shaped driving guide rail 602, the second support cylinder 607 will move synchronously, so that the outer wall of the second support cylinder 607 squeezes the C-shaped frame 509, and the C-shaped frame 509 moves to the right under the squeezing, thereby stretching the second spring and driving the fifth support frame 504 to move to the right through the first support cylinder 507. During the movement of the first support cylinder 507 to the right, the sealing shell 508 will drive the conduit 512 to move to the right, so that the extended long end of the conduit 512 is extended. The pickling liquid enters the cylindrical end of the aluminum rod, and the pickling liquid enters the conduit 512 from the protruding short end of the conduit 512, and is sprayed out through the protruding long end of the conduit 512, so that the pickling liquid inside the cylindrical end of the aluminum rod has improved fluidity, avoiding the problem that the concentration of the pickling liquid becomes low during the cleaning process of the aluminum rod due to poor fluidity inside the cylindrical end of the aluminum rod, and the cleaning effect becomes poor. The fluidity of the pickling liquid inside the cylindrical end of the aluminum rod is improved, and the air bubbles that may remain when the cylindrical end of the aluminum rod is immersed in the pickling liquid can be sprayed out, thereby improving the cleaning efficiency of the pickling liquid. Then the second support cylinder 607 continues to move forward , the outer wall of the second support cylinder 607 no longer squeezes the C-frame 509, and the second spring resets the C-frame 509. The C-frame 509 is reset through the first support cylinder 507, driving the fifth support frame 504 to reset to the left. At the same time, the first support cylinder 507 moves to the left and drives the conduit 512 to move to the left through the sealing shell 508, so that the extended long end of the conduit 512 is separated from the cylindrical end of the aluminum rod, thereby resetting the conduit 512. The conductive claw 611 continues to move along the special-shaped driving guide rail 602, so that the conductive claw 611 drives the aluminum rod to separate from the acid immersion liquid, thereby completing the acid immersion cleaning of the aluminum rod.

[0040] As the conductive claw 611 continues to move along the special-shaped driving guide rail 602, it will carry the aluminum rod downward and fall into the electrolyte of the second electroplating tank 501 from the front to the back. Since the electrolyte in the electroplating tank 501 is an acidic nickel plating solution, a layer of nickel film can be formed on the surface of the aluminum rod during the electrochemical reaction, thereby improving the antioxidant capacity and surface strength of the aluminum rod. The external DC power supply is started, and the current of the external DC power supply flows to the consumable plate 5011 through the wire, and is conducted to the aluminum rod through the acidic nickel plating solution. Finally, the current passes through the conductive claw 611 and The wire flows back to the external DC power supply. During the current conduction process, the consumable plate 5011, as the anode of the electrochemical reaction, loses electrons, thereby releasing nickel ions, and the aluminum rod, as the cathode of the electrochemical reaction, gains electrons, thereby forming a nickel film on its surface. It is worth noting that since the conductive claw 611 contacts the aluminum rod through the edge, the contact area between the conductive claw 611 and the aluminum rod is very small, and the conductive claw 611 will not affect the electroplating effect during the electroplating process of the aluminum rod; since the nickel plating solution is acidic, hydrogen will be precipitated on the surface of the aluminum rod during the electrochemical reaction, thereby The nickel plating quality of the aluminum rod surface is reduced. At this time, the process of the conduit 512 spraying out the acidic nickel plating solution is repeated. The acidic nickel plating solution continues to flow in the electroplating tank 501, so that the concentration of the acidic nickel plating solution around the aluminum rod remains stable, and the hydrogen bubbles on the surface of the aluminum rod are blown away to prevent the hydrogen bubbles from hindering the electroplating, thereby improving the efficiency of the acidic nickel plating solution in forming a nickel film on the surface of the aluminum rod. At the same time, the process of the second support cylinder 607 driving the conduit 512 to move in the left and right directions is repeated. The extended long end of the conduit 512 extends into the cylindrical end of the aluminum rod and sprays out the acidic nickel plating solution, so that the cylindrical end of the aluminum rod The internal acidic nickel plating liquid has improved fluidity, thus avoiding the problem that the concentration of the acidic nickel plating liquid becomes lower during the electroplating process and the electroplating effect becomes worse due to the poor fluidity inside the cylindrical end of the aluminum rod. The fluidity of the acidic nickel plating liquid inside the cylindrical end of the aluminum rod is improved, and the air bubbles and hydrogen bubbles that may remain when the cylindrical end of the aluminum rod is immersed in the pickling solution can be sprayed out, thereby improving the electroplating efficiency of the pickling solution. After that, the conductive claw 611 continues to move along the special-shaped driving guide rail 602 to reset the conduit 512. The conductive claw 611 drives the aluminum rod out of the acidic nickel plating liquid, thereby completing the nickel plating process of the aluminum rod.

[0041] In the process of the conductive claw 611 driving the aluminum rod to continue to move forward, the aluminum rod is immersed in the acid copper plating solution, the acid nickel plating solution and the alkaline copper plating solution in turn, and the conduit 512 repeats the above process of spraying electrolyte and moving left and right, so as to realize copper plating, nickel plating and copper plating on the surface of the aluminum rod in turn, so that the aluminum rod is processed into a terminal. It is worth noting that the copper film formed on the surface of the aluminum rod by the acid copper plating solution has a high hardness, which can provide higher mechanical strength while providing good conductivity for the terminal. The copper film formed on the surface of the terminal by the alkaline copper plating solution has a high toughness, which can provide good compressive strength while providing good conductivity for the terminal, thereby improving the installation stability of the terminal. After that, the conductive claw 611 drives the terminal to continue to move forward, so that the terminal is separated from the above electrolyte and immersed in the cleaning solution of the rearmost electroplating tank 501. The conduit 512 repeats the above process of spraying cleaning solution and moving left and right, so that the electroplating solution attached to the surface of the terminal is cleaned, and then the conductive claw 611 continues to drive the terminal to move, so that the terminal is separated from the cleaning solution and continues to move along the special-shaped driving guide rail 602.

[0042] As the conductive claw 611 continues to move along the special-shaped driving guide rail 602, the second friction roller 606 will rotate along the special-shaped driving guide rail 602. The rotation of the second friction roller 606 changes the moving direction to forward movement. As the second friction roller 606 moves forward, the bottom of the cylindrical outer wall of the second friction roller 606 will rub against the second friction rod 8 to roll. The second friction roller 606 rotates through the second bevel gear set 605 to drive the driving cylinder 609 to rotate and make the second clockwork spring store elastic potential energy. The driving cylinder 609 rotates through the several second slide grooves of the second slide groove plate 610 to push the corresponding conductive claw 611, so that the several conductive claws 611 slide close to each other in the several first slide grooves of the first slide groove plate 608. At this time, the wiring terminal is disengaged from the conductive claw 611, so that the wiring terminal falls downward. At this time, a receiving device can be placed under the wiring terminal to realize the collection of the wiring terminal. The special-shaped transmission belt 603 continues to drive the sixth support frame 604 to move forward, and the sixth support frame 604 moves through the second bevel gear set 605 to drive the second friction roller 606 to continue to move forward, so that the second friction roller 606 disengages from the second friction rod 8, and the second friction roller 606 loses the friction limit, so that the second clockwork spring releases the elastic potential energy to restore the shape, and the second clockwork spring restores the shape and drives the second friction roller 606 to rotate and reset through the second bevel gear set 605, and drives the second slide plate 610 to rotate and reset through the driving cylinder 609, and the driving cylinder 609 rotates through several second slide grooves of the second slide plate 610 to push the corresponding conductive claws 611, so that the several conductive claws 611 slide away from each other in several first slide grooves of the first slide plate 608, and the conductive claws 611 are reset, and then the special-shaped transmission belt 603 continues to drive the sixth support frame 604 to move until the sixth support frame 604 is reset.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.

10. The method for processing a corrosion-resistant terminal according to claim 9, characterized in that: The following steps are involved: S1: placing an unformed terminal aluminum bar into a material discharge trough (211), and rotating the output shaft of the first motor (214) clockwise to move the T-shaped front stamping die (208) backwards. The backward movement of the T-shaped front stamping die (208) drives the feeding block (210) to move synchronously, so that the aluminum bar enters the stamping positioning block (212). The aluminum bar is squeezed by the T-shaped front stamping die (208) and the stamping rear die (205). At this time, one end of the aluminum bar is stamped into a cylindrical shape by the T-shaped front stamping die (208), thereby achieving preliminary processing of the terminal aluminum bar; S2: the output shaft of the first motor (214) rotates counterclockwise, causing the stamping upper die (203) to move downward, the stamping rear die (205) to move backward, and the stamping upper die (203) to contact and squeeze the aluminum rod, so that the other end of the aluminum rod becomes flat under the joint stamping of the stamping upper die (203) and the stamping lower die (2031), thereby achieving further processing of the aluminum rod of the terminal; S3: Repeat step S1, and when a new aluminum rod slides in the stamping positioning block (212), the stamped aluminum rod is pushed onto the conveyor belt (301). The aluminum rod is limited by the edge of the second adjustment block (303) and rotates, so that the cylindrical end of the aluminum rod faces the hanging rod (306). If the sliding distance of the flat end of the aluminum rod is too large, the aluminum rod is limited by the edge of the first adjustment block (302) and rotates, and finally hangs on the hanging rod (306). The aluminum rod rotates due to its own center of gravity, so that the angle of the aluminum rod is adjusted; S4: starting the special-shaped driving guide rail (602), the special-shaped driving guide rail (602) causes the conductive claw (611) and the aluminum rod on the hanging rod (306) to move synchronously, the first friction rod (7) contacts the second friction roller (606), causing the conductive claw (611) to contract, and then the first friction rod (7) and the second friction roller (606) are separated, causing the conductive claw (611) to clamp the aluminum rod; S5: starting the second motor (502) so that the pressing block (511) squeezes the electrolyte in the conduit (512) to flow, starting the external DC power supply, and the aluminum rod slides into the electrolyte under the drive of the special-shaped driving guide rail (602). The external DC power supply flows from the consumable plate (5011) to the aluminum rod, so that the surface of the aluminum rod is plated with a metal film. When the aluminum rod is around the conduit (512), the electrolyte flows to remove bubbles on the surface of the aluminum rod and replenish the electrolyte concentration. After acid immersion, nickel plating, acid copper plating, nickel plating, alkaline copper plating, and cleaning with a cleaning solution, the aluminum rod becomes a terminal, thereby realizing the processing of corrosion-resistant terminal blocks; S6: The second friction rod (8) contacts the second friction roller (606), causing the conductive claw (611) to contract, and the connection terminal is separated from the conductive claw (611).
