The prior art is to make corresponding styles of copper and aluminum materials, connect the two ends by friction welding and form terminals through cutting. Since copper and aluminum have different activities when electrified, they are extremely prone to electrochemical oxidation when exposed to humid air. Moreover, due to different resistance values and thermal melting points around the welding surface, the terminals are prone to heat generation and force fracture, seriously affecting the distribution and use of electricity.
[0003] A corrosion-resistant copper-aluminum terminal is now proposed. The shape is processed and electroplated with aluminum as the base material. The surface of the copper-aluminum terminal is plated with a nickel layer and a copper layer, which improves the corrosion resistance of the copper-aluminum terminal.

[0017] A processing method for a corrosion-resistant terminal includes the following steps:
[0018] S1: Place the unformed terminal aluminum rod into the feeding groove. The output shaft of the first motor rotates clockwise, causing the T-shaped stamping front die to move backward. The backward movement of the T-shaped stamping front die drives the feeding block to move synchronously, enabling the aluminum rod to enter the stamping positioning block. The aluminum rod is extruded by the T-shaped stamping front die and the stamping rear die. At this time, one end of the aluminum rod is stamped into a cylindrical shape by the T-shaped stamping front die, realizing the preliminary processing of the terminal aluminum rod for the connection.
[0019] 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 extrudes the aluminum rod, causing the other end of the aluminum rod to become flat under the combined stamping of the stamping upper die and the stamping lower die, realizing the further processing of the terminal aluminum rod for the connection.
[0020] S3: Repeat step S1. When the new aluminum rod slides within the stamping positioning block, it pushes the stamped aluminum rod onto the conveyor belt. The aluminum rod rotates when restricted by the edge of the second alignment block, causing the cylindrical end of the aluminum rod to face the hanging rod. If the sliding distance of the flat end of the aluminum rod is too large, the aluminum rod rotates when restricted by the edge of the first alignment block and finally hangs on the hanging rod. The aluminum rod rotates under the influence of its own center of gravity to achieve angle adjustment of the aluminum rod.
[0021] S4: Start the special-shaped drive guide rail. The special-shaped drive guide rail moves the conductive claw synchronously with the aluminum rod on the hanging rod. The first friction rod contacts the second friction roller, causing the conductive claw to contract. Then, the first friction rod disengages from the second friction roller, and the conductive claw clamps the aluminum rod.
[0022] S5: Start the second motor to cause the pressing block to squeeze the electrolyte in the conduit to flow. Start the external DC power supply. The aluminum rod slides into the electrolyte under the drive of the special-shaped drive guide rail. The external DC power supply flows from the consumable plate to the aluminum rod, causing a metal film to be plated on the surface of the aluminum rod. When the aluminum rod is around the conduit, the flowing electrolyte removes the bubbles on the surface of the aluminum rod and replenishes the electrolyte concentration. After acid pickling, nickel plating, acid copper plating, nickel plating, alkaline copper plating, and cleaning with a cleaning solution, the aluminum rod becomes a terminal, achieving the processing of corrosion-resistant terminals.
[0023] S6: The second friction rod contacts the second friction roller, causing the conductive claw to contract, and the terminal disengages from the conductive claw.
[0024] Compared with the prior art, the present invention has the following advantages: 1. In the present invention, by starting the first motor, 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, realizing the alternate operation of the terminal stamping process. The backward movement of the T-shaped stamping front die pushes the feeding block to move synchronously through the first spring, pushing the aluminum rod into the blanking guide rail and along the blanking guide rail into the stamping positioning block, enabling the aluminum rod to be stamped by the T-shaped stamping front die and the stamping rear die, realizing automatic feeding and stamping of the aluminum rod. Moreover, the moving pawl will automatically clean the remaining materials during the stamping process, effectively improving the stamping efficiency of the aluminum rod.
[0025] 2. In the present invention, by squeezing the electrolyte in the conduit with the pressing block, the electrolyte is ejected from the extended long end of the conduit, blowing away the bubbles on the outer surface of the aluminum rod, preventing electroplating depressions on the surface of the aluminum rod, and improving the processing quality of terminal electroplating.
[0026] 3. In the present invention, by squeezing the C-shaped frame with the second support cylinder, the conduit extends into the cylindrical end of the aluminum rod. The electrolyte ejected from the conduit can blow away the bubbles on the inner surface of the aluminum rod, preventing bubbles from accumulating inside the cylindrical end of the aluminum rod, resulting in electroplating defects where the inner surface of the cylindrical end of the aluminum rod cannot contact the electrolyte, thereby improving the processing quality of terminal electroplating.

[0048] A processing method for a corrosion-resistant terminal, characterized by comprising the following steps:
[0049] S1: Place the unformed terminal aluminum bar into the feeding groove 211. The output shaft of the first motor 214 rotates clockwise, so that the T-shaped stamping front die 208 moves backward. The backward movement of the T-shaped stamping front die 208 drives the feeding block 210 to move synchronously, so that the aluminum bar enters the stamping positioning block 212.

At this time, one end of the aluminum bar is stamped into a cylindrical shape by the T-shaped stamping front die 208, realizing the preliminary processing of the terminal aluminum bar for the connection.
[0050] S2: The output shaft of the first motor 214 rotates counterclockwise, causing the stamping upper die 203 to move downward and the stamping lower die 205 to move backward. The stamping upper die 203 contacts and extrudes the aluminum rod, making the other end of the aluminum rod become flat under the combined stamping of the stamping upper die 203 and the stamping lower die 2031, realizing the further processing of the aluminum rod for the connection terminal.
[0051] S3: Repeat step S1. When the new aluminum rod slides in the stamping positioning block 212, it pushes the stamped aluminum rod onto the conveyor belt 301. The aluminum rod rotates due to being limited by the edge of the second aligning block 303, making the cylindrical end of the aluminum rod face the hanging rod 306. If the sliding distance of the flat end of the aluminum rod is too large, the aluminum rod rotates due to being limited by the edge of the first aligning block (302), and finally hangs on the hanging rod 306. The aluminum rod rotates under the influence of its own center of gravity, realizing the angle adjustment of the aluminum rod.
[0052] S4: Start the special-shaped driving guide rail 602. The special-shaped driving guide rail 602 makes the conductive claw 611 move synchronously with the aluminum rod on the hanging rod 306. The first friction rod 7 contacts the second friction roller 606, causing the conductive claw 611 to contract. Then the first friction rod 7 disengages from the second friction roller 606, enabling the conductive claw 611 to clamp the aluminum rod.
[0053] S5: Start the second motor 502 to make the pressing block 511 squeeze the electrolyte in the conduit 512 to flow. Start the external DC power supply. 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, plating a metal film on the surface of the aluminum rod. When the aluminum rod is around the conduit 512, the flowing electrolyte removes the bubbles on the surface of the aluminum rod and replenishes the electrolyte concentration. After acid pickling, nickel plating, acid copper plating, nickel plating, alkaline copper plating, and cleaning with a cleaning solution, the aluminum rod becomes a connection terminal, realizing the processing of the corrosion-resistant connection terminal.
[0054] S6: The second friction rod 8 contacts the second friction roller 606, causing the conductive claw 611 to contract, and the connection terminal disengages from the conductive claw 611.
[0055] When it is necessary to process an unformed terminal aluminum rod, first place the aluminum rod into the feeding chute 211. At this time, the stamping upper die 203 and the stamping lower die 2031 are in contact. By starting the first motor 214, the output shaft of the first motor 214 rotates clockwise and drives the second lead screw 213 to rotate synchronously, so that the second lead screw 213 drives the stamping upper die 203 to move upward along the optical rod and separate from the stamping lower die 2031. During the upward movement of the stamping upper die 203, the stamping rear die 205 is driven forward by the connecting rod 204. The forward movement of the stamping rear die 205 causes the first lead screw 207 to rotate. The rotation of the first lead screw 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 backward. Since the thread pitch at the front end of the first lead screw 207 is longer than that at the rear end, and the helix directions of the two pitch are opposite, the feeding block 210 first pushes the aluminum rod at the bottom of the feeding chute 211 into the blanking guide rail of the third support frame 209, and the aluminum rod enters the stamping positioning block 212 along the blanking 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 backward until the feeding block 210 contacts the stamping positioning block 212 and blocks 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. 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.
[0056] When one end of the aluminum rod is stamped and completed, at this time, the T-shaped stamping front die 208 is located inside 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, so as to drive the stamping upper die 203 to move downward along the optical rod through the second lead screw 213. The downward movement of the stamping upper die 203 drives the stamping rear die 205 to move backward away from the stamping positioning block 212 through the connecting rod 204. At the same time, the T-shaped stamping front die 208 moves forward away from the aluminum rod to be stamped. At this time, the movement of the aluminum rod is restricted by the damping on the inner wall of the stamping positioning block 212. The positioning of the aluminum rod after stamping is realized through the damping on the inner wall of the stamping positioning block 212, effectively preventing the position change of the aluminum rod caused by the frictional force generated when the T-shaped stamping front die 208 and the stamping rear die 205 move away from each other and reset, and avoiding the misalignment problem during the next stamping. At this time, the stamping upper die 203 continues to move downward to contact the stamping lower die 2031 and realizes the re-stamping of the aluminum rod, stamping the other end of the aluminum rod into a flat shape. During the process of stamping the other end of the aluminum rod flat by the stamping upper die 203, the surplus material at the other end of the aluminum rod will spread around along the stamping lower die 2031 to generate surplus material, and is extruded by the bottom edge of the stamping upper die 203, resulting in a large shear stress 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 surplus material breaks along the bottom edge of the stamping upper die 203 and detaches from the other end of the aluminum rod. At this time, the processing of the aluminum rod terminal shape is completed. At the same time, the first spring is released and drives the feeding block 210 to move forward and reset. When the feeding block 210 moves along the feeding groove 211, the inclined surface at the top of the front side of the feeding block 210 jacks up the new aluminum rod in the feeding groove 211, so that the aluminum rod in the feeding groove 211 is located above the feeding block 210. When the feeding block 210 resets, it will disengage from the feeding groove 211, causing the new aluminum rod to fall to the bottom of the feeding groove 211, realizing the intermittent feeding function. Repeat the above steps to realize the automatic processing of the aluminum rod terminals.
[0057] During the stamping and forming process of the aluminum rod, after the surplus material is sheared off from the aluminum rod by the stamping upper die 203 and falls onto the second base 201 under the action of gravity, the above-mentioned processing steps of the aluminum rod terminal are repeated. The output shaft of the first motor 214 rotates clockwise to drive the stamping rear die 205 to move forward. As the stamping rear die 205 moves forward, it drives the pawl 216 to move synchronously through the convex shell 215. During the forward movement of the pawl 216, its bottom will contact the surplus material, causing the pawl 216 to rotate counterclockwise inside the convex shell 215. The bottom of the pawl 216 slides along the contact position with the surplus material to the top of the surplus material. During the rotation of the pawl 216, the first spring will be wound up. Then the pawl 216 continues to move forward following the convex shell 215, causing the bottom of the pawl 216 to slide along the top of the surplus material until the bottom of the pawl 216 disengages from the surplus material. At this time, the first spring resumes and drives the pawl 216 to rotate back to its original position. Then the convex shell 215 continues to slide forward until the stamping rear die 205 completes a preliminary processing move forward. At this time, the convex shell 215 slides into the rectangular groove behind the stamping positioning block 212. Then the output shaft of the first motor 214 rotates counterclockwise to drive the stamping rear die 205 to move backward, causing the stamping rear die 205 to drive the pawl 216 to move synchronously through the convex shell 215. When the pawl 216 moves backward, its bottom contacts the surplus material again. Due to the limit of the front side inside the convex shell 215 on the pawl 216, when the pawl 216 moves backward, it pushes the surplus material to move synchronously along the second base 201 until the pawl 216 pushes the surplus material off the top rear end of the base 201, realizing the cleaning of the surplus material under the stamping upper die 203, avoiding the accumulation of the surplus material under the stamping upper die 203 from affecting the stamping process of the stamping upper die 203, and further improving the processing efficiency of the aluminum rod.
[0058] During the repetition of the above-mentioned processing steps of the aluminum rod terminal, the T-shaped stamping front die 208 moves backward, which will push the first spring and the feeding block 210 backward. The feeding block 210 pushes another aluminum rod at the bottom of the feeding groove 211 into the feeding guide rail of the third support frame 209. Another aluminum rod enters the stamping positioning block 212 along the feeding guide rail of the third support frame 209, causing the rear end of another aluminum rod to contact the cylindrical end of the aluminum rod in the stamping positioning block 212 and pushing the aluminum rod in the stamping positioning block 212 backward. The aluminum rod in the stamping positioning block 212 disengages from the stamping positioning block 212 and falls onto the stamping lower die 2031. During the continuous backward movement of the stamped aluminum rod, its center of gravity will move away from directly above the stamping lower die 2031, causing the stamped aluminum rod to fall along the rear edge of the top of the stamping lower die 2031 and enter the feeding groove of the second base 201. Since the center of gravity of the stamped aluminum rod is biased towards the flat end, the flat end of the aluminum rod always faces backward and downward when it falls, and finally the aluminum rod falls onto the conveyor belt 301 with the flat end facing backward, realizing the automatic feeding of the stamping processing mechanism 2 and further improving the processing efficiency of the terminal.
[0059] When the aluminum rod lands on the conveyor belt 301, the conveyor belt 301 is started, and the conveyor belt 301 drives the aluminum rod to move to the right. During 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 alignment block 303, resulting in the flat end of the aluminum rod being limited by the second alignment 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 alignment block 303 rotates counterclockwise, causing the cylindrical end of the aluminum rod to continue moving to the right. During the process of the cylindrical end of the aluminum rod moving to the right, the flat end of the aluminum rod is squeezed and restricted by the left front edge of the second alignment block 303, causing the flat end of the aluminum rod to move to the left, thus realizing that the cylindrical end of the aluminum rod faces the drive shaft 304; then the aluminum rod continues to move to the right under the drive of the conveyor belt 301, causing the aluminum rod to disengage from the second alignment 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 alignment block 302. Since the aluminum rod continues to move to the right, the rear left edge of the first alignment block 302 squeezes the flat end of the aluminum rod, thereby causing the aluminum rod to rotate, and the cylindrical end of the aluminum rod will more precisely face the drive shaft 304, facilitating 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, causing the aluminum rod to rotate and disengage from the first alignment block 302.
[0060] While the conveyor belt 301 is running, it also drives the drive shaft 304 to rotate counterclockwise through the belt drive group 305. The rotation of the drive shaft 304 drives the hanging rod 306 to rotate synchronously. During the process of the hanging rod 306 rotating and approaching the conveyor belt 301, the aluminum rod is also moving to the right, causing one end of the hanging rod 306 to 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 drives the aluminum rod to rotate counterclockwise on the conveyor belt 301. It should be noted that since the drive shaft 304 is inclined, the hanging rod 306 has an inclined angle. 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 into the cylindrical end of the aluminum rod. Due to the inclined angle of the hanging rod 306, the cylindrical end of the aluminum rod smoothly slides into the bottom of the hanging rod 306, and at the same time, the aluminum rod will not contact the first alignment block 302 during the rotation process; when the aluminum rod disengages from the conveyor belt 301, the cylindrical end of the aluminum rod will slide along the hanging rod 306 under the action of its own gravity until one end of the hanging rod 306 contacts the inner end of the cylindrical part of the aluminum rod. At this time, the side wall of the hanging rod 306 contacts the inner wall of the cylindrical end of the aluminum rod. At the same time, under the action of gravity, the aluminum rod will make its center of gravity located below the hanging rod 306. As a result, the aluminum rod rotates, causing the side of the flat end of the aluminum rod that has been pressed by the stamping lower die 2031 to always face downward, realizing the automatic adjustment of the angle of the aluminum rod. When the hanging rod 306 drives the aluminum rod to rotate so that one end of the hanging rod 306 faces the rear, the operation of the conveyor belt 301 is stopped to facilitate the subsequent clamping of the aluminum rod.
[0061] While the hanging rod 306 rotates, the special-shaped drive guide rail 602 is activated. The special-shaped drive guide rail 602 drives the special-shaped transmission belt 603 to run, causing the special-shaped transmission belt 603 to drive two adjacent sliding brackets 612 to move synchronously closer to the hanging rod 306. The two sliding brackets 612 slide together to drive the sixth support frame 604 to move synchronously. It should be noted that when the two sliding brackets 612 approach the hanging rod 306, they will rotate left and right and up and down along the special-shaped transmission belt 603. The two sliding brackets 612 drive the sixth support frame 604 to rotate through the rotating frame 613, and store and release the elastic potential energy of the third spring. The sixth support frame 604 drives the first chute plate 608 to slide through the second support cylinder 607, thereby driving the conductive claws 611 to move synchronously. During the movement of the conductive claws 611, they will gradually approach the flat end of the aluminum rod on the hanging rod 306. It should be noted that when the conductive claws 611 and the flat end of the aluminum rod on the hanging rod 306 are in the same position in the front-rear direction, the conveyor belt 301 is started again, causing the conveyor belt 301 to drive the hanging rod 306 to drive the aluminum rod to rotate, so that the conductive claws 611 and the flat end of the aluminum rod on the hanging rod 306 always maintain the same position. The conductive claws 611 can extend into the round hole of the flat end of the aluminum rod during the process of approaching the flat end of the aluminum rod. During the process of the conductive claws 611 moving closer to the flat end of the aluminum rod, the sixth support frame 604 moves to drive the second friction roller 606 to move forward through the second bevel gear set 605, so that the bottom of the cylindrical outer wall of the second friction roller 606 contacts the first friction rod 7 and rolls. The rotation of the second friction roller 606 drives the drive cylinder 609 to rotate through the second bevel gear set 605 and stores elastic potential energy in the second winding spring. The rotation of the drive cylinder 609 pushes the corresponding conductive claws 611 through several second chutes of the second chute plate 610, causing several conductive claws 611 to slide closer to each other in several first chutes of the first chute plate 608, facilitating the insertion of several conductive claws 611 into the round holes of the flat end of the aluminum rod and improving the insertion of the conductive claws 611 into the round holes of the flat end of the aluminum rod;When the sixth support frame 604 is directly above the drive shaft 304, at this time, the conductive claws 611 have extended into the round holes at the flat ends of the aluminum rods. The special-shaped drive 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. The movement of the sixth support frame 604 drives the second friction roller 606 to continue to move through the second bevel gear set 605, so that the second friction roller 606 disengages from the first friction rod 7, and the second friction roller 606 loses frictional limitation. As a result, the second clock spring releases its elastic potential energy and resumes its shape. The resumption of the shape of the second clock spring drives the second friction roller 606 to rotate and reset through the second bevel gear set 605, and drives the second chute plate 610 to rotate and reset through the drive cylinder 609. The rotation of the drive cylinder 609 pushes the corresponding conductive claws 611 through several second chutes of the second chute plate 610, so that the several conductive claws 611 slide away from each other in several first chutes of the first chute plate 608, and the inner wall of the round hole at the flat end of the aluminum rod is squeezed by their edges, so that the aluminum rod is clamped by the conductive claws 611, thereby realizing the clamping of the aluminum rod by the conductive claws 611. As the sixth support frame 604 continues to move along the special-shaped drive 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 disengages from the hanging rod 306. After the cylindrical end of the aluminum rod completely disengages from the hanging rod 306, the conductive claws 611 will drive the aluminum rod to move along the special-shaped drive guide rail 602 towards the electroplating bath 501.;
[0062] During the process of the aluminum rod approaching the electroplating bath 501, the second motor 502 is started. 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 rotating shaft. The rotation of the first friction roller 506 drives the drive rod 510 to rotate counterclockwise through the first bevel gear set 505. The rotation of the drive rod 510 causes the pressing block 511 to rotate, so that the cylindrical end of the pressing block 511 changes the position of squeezing the conduit 512 in the counterclockwise direction. The internal capacity of the extended short end of the conduit 512 increases, and a vacuum appears inside the conduit 512. As a result, the extended short end of the conduit 512 sucks the electrolyte towards the electroplating bath 501. The electroplating solution enters the inside of the conduit 512 from the extended short end of the conduit 512. At the same time, the internal capacity of the extended long end of the conduit 512 decreases, so that the electrolyte inside the conduit 512 is squeezed by the cylindrical end of the pressing block 511, so that the electrolyte sprays out from the extended long end of the conduit 512, causing the electrolyte in the electroplating bath 501 to flow, as 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.
[0063] 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.
[0064] During the subsequent process in which the conductive claw 611 drives the aluminum rod to continue moving forward, the aluminum rod is successively immersed in acidic copper plating solution, acidic nickel plating solution, and alkaline copper plating solution, and the conduit 512 repeats the above process of spraying electrolyte and moving left and right, successively realizing copper plating, nickel plating, and copper plating on the surface of the aluminum rod, so that the aluminum rod is processed into a terminal. It should be noted that the copper film formed by the acidic copper plating solution on the surface of the aluminum rod has a relatively high hardness and can provide higher mechanical strength on the premise of providing good conductivity for the terminal. The copper film formed by the alkaline copper plating solution on the surface of the terminal has relatively high toughness and can provide good compressive resistance on the premise of 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 moving forward, so that the terminal disengages from the above electrolyte and is immersed in the cleaning solution in the rearmost plating bath 501. The conduit 512 repeats the above process of spraying the cleaning solution and moving left and right, so that the plating solution attached to the surface of the terminal is cleaned. Subsequently, the conductive claw 611 continues to drive the terminal to move, so that the terminal disengages from the cleaning solution and continues to move along the special-shaped drive rail 602.
[0065] During the process in which the conductive claw 611 continues to move along the special-shaped drive rail 602, the second friction roller 606 will rotate along the special-shaped drive rail 602. The rotation of the second friction roller 606 changes the moving direction to forward movement. During the forward movement of the second friction roller 606, the bottom of the cylindrical outer wall of the second friction roller 606 will rub against the second friction rod 8 and thus roll. The rotation of the second friction roller 606 drives the drive cylinder 609 to rotate through the second bevel gear set 605 and stores elastic potential energy in the second hairspring. The rotation of the drive cylinder 609 pushes the corresponding conductive claws 611 through several second chutes of the second chute plate 610, so that several conductive claws 611 slide and approach each other in several first chutes of the first chute plate 608. At this time, the terminal disengages from the conductive claws 611, so that the terminal drops downward. At this time, a receiving device can be placed below the terminal to realize the collection of the terminal. The special-shaped transmission belt 603 continues to drive the sixth support frame 604 to move forward. The movement of the sixth support frame 604 drives the second friction roller 606 to continue moving forward through the second bevel gear set 605, so that the second friction roller 606 disengages from the second friction rod 8. The second friction roller 606 loses friction limitation, so that the second hairspring releases elastic potential energy and restores its shape. The restoration of the shape of the second hairspring drives the second friction roller 606 to rotate and reset through the second bevel gear set 605, and drives the second chute plate 610 to rotate and reset through the drive cylinder 609. The rotation of the drive cylinder 609 pushes the corresponding conductive claws 611 through several second chutes of the second chute plate 610, so that several conductive claws 611 slide and move away from each other in several first chutes of the first chute plate 608, realizing the reset of the conductive claws 611. After that, the special-shaped transmission belt 603 continues to drive the sixth support frame 604 to move until the sixth support frame 604 is reset.

8. The processing method of a corrosion-resistant terminal according to claim 7, characterized in that, It includes the following steps: S1: Place the unformed terminal aluminum bar into the feeding groove (211). The output shaft of the first motor (214) rotates clockwise, causing the T-shaped stamping front die (208) to move backward. The backward movement of the T-shaped stamping front die (208) drives the feeding block (210) to move synchronously, enabling the aluminum bar to enter the stamping positioning block (212). The aluminum bar is squeezed by the T-shaped stamping front 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 stamping front die (208), realizing the preliminary processing of the connecting wire terminal aluminum bar. S2: The output shaft of the first motor (214) rotates counterclockwise, causing the stamping upper die (203) to move downward and the stamping rear die (205) to move backward. The stamping upper die (203) contacts and squeezes the aluminum bar, causing the other end of the aluminum bar to become flat under the combined stamping of the stamping upper die (203) and the stamping lower die (2031), realizing the further processing of the connecting wire terminal aluminum bar. S3: Repeat step S1. When the new aluminum bar slides in the stamping positioning block (212), it pushes the stamped aluminum bar onto the conveyor belt (301). The aluminum bar is limited by the edge of the second alignment block (303) and rotates, causing the cylindrical end of the aluminum bar to face the hanging rod (306). If the sliding distance of the flat end of the aluminum bar is too large, the aluminum bar is limited by the edge of the first alignment block (302) and rotates, and finally hangs on the hanging rod (306). The aluminum bar rotates under the influence of its own center of gravity, realizing the angle adjustment of the aluminum bar. S4: Start the special-shaped drive guide rail (602). The special-shaped drive guide rail (602) causes the conductive claw (611) to move synchronously with the aluminum bar on the hanging rod (306). The first friction rod (7) contacts the second friction roller (606), causing the conductive claw (611) to contract. Then the first friction rod (7) disengages from the second friction roller (606), causing the conductive claw (611) to clamp the aluminum bar. S5: Start the second motor (502) to make the pressing block (511) extrude the electrolyte in the conduit (512) to flow. Start the external DC power supply. The aluminum rod slides into the electrolyte under the drive of the special-shaped drive guide rail (602). The external DC power supply flows from the consumable plate (5011) to the aluminum rod to make a metal film plated on the surface of the aluminum rod. When the aluminum rod is around the conduit (512), the flowing electrolyte removes the bubbles on the surface of the aluminum rod and replenishes the electrolyte concentration. After pickling, nickel plating, acid copper plating, nickel plating, alkaline copper plating, and cleaning with a cleaning solution, the aluminum rod becomes a terminal, realizing the processing of a corrosion-resistant terminal; S6: The second friction rod (8) contacts the second friction roller (606) to make the conductive claw (611) contract, and the terminal disengages from the conductive claw (611).
