Description

Technical Field

[0001] The present invention relates to the technical field of copper-aluminum composite plate production, and particularly relates to a device and method for preparing and producing a solid-liquid laminated copper-aluminum composite plate strip. Background Art

[0002] Currently, in the preparation of copper-aluminum composite plate strips, the continuous casting method is mostly used for the production of copper-aluminum composite plate strips, which can effectively improve production efficiency and reduce the generation of oxidation slag.

[0003] The patent with the publication number CN118385539B discloses a device and process for preparing pole column raw materials by continuous casting. This prior art realizes the integrated continuity in the preparation of copper-aluminum composite plate strips, without the need to separately process the copper strip and aluminum liquid, thus improving the preparation efficiency.

[0004] However, the above prior art has the following technical defects:

[0005] First, in order to prevent the aluminum material from falling on the copper plate strip and causing the plate strip to be misaligned during the process of adding aluminum material, this prior art needs to adsorb the copper plate strip feeding position on the surface of the support inner frame to avoid the misalignment of the copper plate strip during the feeding process. However, at this time, the copper plate strip needs to stop advancing, and then the copper plate strip is in an intermittent advancing mode on this device. This advancing mode is slow, resulting in low preparation efficiency of the device.

[0006] Second, at the same time, this prior art simply discharges the aluminum material onto the upper surface of the copper plate strip through the casting nozzle. Since the aluminum liquid is in a semi-molten and semi-solid state, this addition method is likely to cause the aluminum material to pile up on the copper plate strip, with uneven distribution, and finally lead to uneven thickness of the aluminum layer of the copper-aluminum composite plate strip after rolling, reducing the finished product quality.

[0007] In summary, there is still room for improvement in the prior art in terms of improving the production efficiency of the device and the finished product quality. Therefore, those skilled in the art have proposed a device that can limit and fix the copper plate strip during continuous advancement and make the aluminum liquid more evenly distributed. Summary of the Invention

A return spring is arranged inside the fixing seat on one side of one of the clamping parts.

[0016] Preferably, an annular adjustment track is arranged around the conveying mechanism. A limiting block is slidably arranged on one side of each driving electric cylinder on the adjustment track. An L-shaped frame is installed at the end of the limiting block. Two limiting rods extending into the upper cylinder are symmetrically installed on the upper side of the L-shaped frame.

[0017] Preferably, an extrusion block adapted to the trapezoidal block is installed on the side surface of the L-shaped frame. An infrared receiver is installed on one side of each driving electric cylinder on the U-shaped plate. Two infrared transmitters are symmetrically installed on the upper side of the base.

[0018] Preferably, a pushing mechanism is arranged on the U-shaped frame. The pushing mechanism includes two symmetrically arranged mounting plates. A small gear is rotatably installed between the two mounting plates. A driving rack meshing with it is slidably arranged on the side surface of the small gear. A connecting rail is installed on the driving rack. A connecting block adapted to the connecting rail is installed on the side surface of the cylinder.

[0019] Preferably, a circular plate gear-connected to the small gear is rotatably installed on the side surface of one of the mounting plates. A push plate is slidably arranged on one side of each U-shaped frame. A connecting rod is rotatably installed at the edge of the side surface of the circular plate. An L-shaped rod connected to the circular plate is rotatably installed at the end of the connecting rod.

[0020] On the other hand, the present application also discloses a method for preparing and producing a solid-liquid laminated copper-aluminum composite plate strip, which comprises the following steps:

[0021] S1. Fix the copper plate. During the forward movement of the copper plate strip, use the conveying mechanism and the fixing mechanism to limit and fix it.

[0022] S2. Add aluminum material. Add a semi-molten plate at the position where the copper plate strip is limited and fixed to fix the aluminum liquid.

[0023] S3. Pull the copper plate. Through the cooperation of the fixing mechanism and the driving mechanism, pull the part of the copper plate strip where the aluminum material is added, so as to make the corresponding part vibrate.

[0024] S4. Re-adsorption. Through the cooperation of the J-shaped limiting rail and the fixing mechanism, the copper plate strip is re-adsorbed and fixed until it moves out of the fixing range.

[0025] S5. Cast-roll the plate strip. Use the rolling mechanism to cast-roll the copper plate strip with aluminum material added on its upper surface.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] First, through the cooperation of the conveying mechanism and the fixing mechanism, the present invention enables multiple suction cups on the fixing mechanism to move along the rotation trajectory of the conveyor belt. Moreover, by using the fixing mechanism in cooperation with the Z-shaped limiting rail and the J-shaped limiting rail, the multiple moving suction cups on the inner side adsorb and fix the advancing copper plate strip, thereby realizing the limit and fixation of the feeding area of the copper plate strip during its forward movement. And the copper plate strip is always in a forward state, replacing the previous intermittent forward mode, increasing the forward speed of the copper plate strip, and enhancing the production efficiency of the device.

[0028] Second, through the cooperation of the fixing mechanism and the driving mechanism, after the aluminum material is added to the copper plate strip, when the infrared receiver receives the infrared light from the infrared emitter, the driving electric cylinder is shortened to lower the corresponding left and right suction cups, thereby pulling the part of the copper plate strip where the aluminum material is added. Then, the adsorption is released through structural changes, and the copper plate strip vibrates at a high frequency during the restoration process, making the aluminum material above the plate strip evenly distributed through vibration, ensuring that the aluminum layer thickness of the copper-aluminum composite plate strip cast-rolled later is uniform, and improving the finished product quality.

Detailed implementation mode

[0044] The following combines Figure 1 - Figure 13 to describe the embodiments of the present invention in detail.

[0045] The embodiment of the present application discloses a device and method for preparing and producing a solid-liquid laminated copper-aluminum composite strip. Through the cooperation of the conveyor mechanism and the fixing mechanism, multiple suction cups on the fixing mechanism move around the rotation trajectory of the conveyor belt, and by using the fixing mechanism in cooperation with the Z-shaped limit track and the C-shaped limit track, the multiple moving suction cups on the inner side adsorb and fix the advancing copper strip, so as to realize the limit and fixation of the feeding area of the copper strip during the advancing process of the copper strip, and the copper strip is always in the advancing state, replacing the previous intermittent advancing mode, improving the advancing speed of the copper strip, and enhancing the production efficiency of the device.

[0046] Embodiment 1:

[0047] As Figure 1 and Figure 2As shown in the figure, it includes a strip-shaped base 1. A conveying roller 8 is rotatably arranged above the base 1. A feeding mechanism 6 and a rolling mechanism 7 are respectively arranged on one side of the conveying roller 8. The conveying roller 8 is used to support and convey the copper strip. The feeding mechanism 6 is used to add semi-solid aluminum liquid to the upper surface of the copper plate. The rolling mechanism 7 is used to roll the copper strip after adding aluminum liquid into a copper-aluminum composite strip.

[0048] As Figure 3 shown, the feeding mechanism 6 includes two symmetrically arranged mounting frames 601. A storage tank 602 is installed on the upper side of the mounting frame 601. An opening is provided on the lower side of the storage tank 602. The high-temperature molten aluminum liquid is put into the interior of the storage tank 602 through the input end, and then it is left to stand in the storage tank 602 to form a semi-molten plate solid state.

[0049] As Figure 3 shown, a cloth pipe 603 adapted to it is installed at the end of the opening. Two discharging electric cylinders 604 are symmetrically installed on the side of the cloth pipe 603 near the bottom. A baffle 605 for blocking the lower end of the cloth pipe 603 is jointly installed at the ends of the two discharging electric cylinders 604. When the discharging electric cylinder 604 extends, it drives the baffle 605 to move to open the lower port of the cloth pipe 603. Then the cloth in the storage tank 602 passes through the cloth pipe 603 and flows out in a flat shape onto the upper surface of the copper strip, realizing the addition of aluminum material.

[0050] As Figure 4 shown, the rolling mechanism 7 includes a U-shaped seat 701 installed on the base 1. Two motors 702 are symmetrically installed on the side surface of the U-shaped seat 701. A rolling roller 703 rotatably connected to the inner side surface of the U-shaped seat 701 is installed at the driving end of the motor 702. The two motors 702 drive the two rolling rollers 703 to rotate towards each other. The copper plate with aluminum material added to its upper surface passes between the two rolling rollers 703, and is continuously cast and rolled to obtain a copper-aluminum composite strip.

[0051] As Figure 5 and Figure 6 shown, a conveying mechanism 2 is arranged on the upper side of the base 1. The conveying mechanism 2 includes two symmetrically arranged U-shaped frames 201. Two conveying wheels 202 are rotatably installed on the lower side of the U-shaped frames 201. A conveyor belt 203 is jointly arranged by the two conveying wheels 202. A motor 204 with a driving end fixedly connected to one of the conveying wheels 202 is installed on the upper side of the U-shaped frame 201. The running motor 204 drives the conveying wheel 202 connected to it to rotate, and the rotating conveying wheel 202 cooperates with the other conveying wheel 202 to drive the conveyor belt 203 to rotate.

[0052] As Figure 5 、 Figure 7 and Figure 8As shown, a fixing mechanism 3 is provided on the conveyor belt 203. The fixing mechanism 3 includes a plurality of U-shaped plates 301 evenly distributed. A cylinder 306 is provided on each U-shaped plate 301. A suction cup 307 is installed on the upper side of the cylinder 306. The rotating conveyor belt 203 drives all the suction cups 307 to move around its track, and at the same time, the moving suction cups 307 are used to support the advancing copper strip.

[0053] As Figure 7 and Figure 8 shown, a piston 308 adapted to it is slidably provided in the cylinder 306. A secondary spring 310 is provided below the piston 308 inside the cylinder 306. An annular magnet 309 is provided at the center of the inner bottom surface of the cylinder 306. When the piston 308 descends, the secondary spring 310 is compressed until the piston 308 adsorbs to the annular magnet 309. At the same time, the descending piston 308 pumps the air in the suction cup 307 into the cylinder 306, creating a negative pressure inside the suction cup 307, thereby fixing the copper strip on the plurality of moving suction cups 307 and preventing the copper strip from being displaced during the process of adding aluminum material.

[0054] As Figure 7 and Figure 8 shown, the lower end of the piston 308 extends to the outside of the cylinder 306 and is installed with a lower L-shaped plate 311. On the upper side of the base 1, a Z-shaped limiting rail 11 is installed on one side of each conveying mechanism 2. A J-shaped limiting rail 12 adapted to it is provided on one side of the Z-shaped limiting rail 11. A slider 312 adapted to the Z-shaped limiting rail 11 and the J-shaped limiting rail 12 is installed on the side surface of the lower L-shaped plate 311. After the moving slider 312 enters the Z-shaped limiting rail 11, it descends through the diversion of the Z-shaped limiting rail 11, thereby driving the piston 308 to descend through the lower L-shaped plate 311. When the slider 312 enters the J-shaped limiting rail 12, it descends through the diversion. When it is about to leave quickly, the slider 312 rises through the diversion of the J-shaped limiting rail 12, thereby driving the piston 308 to rise and releasing the adsorption of the suction cup 307 to the copper strip.

[0055] In summary, the rotating conveyor belt 203 drives the suction cups 307 thereon to move around their tracks. When the slider 312 contacts the Z-shaped limit rail 11, it is guided down by the Z-shaped limit rail 11, and then the descending slider 312 drives the piston 308 down through the lower L-shaped plate 311, compressing the secondary spring 310 until the piston 308 is adsorbed by the annular magnet 309. At the same time, the descending piston 308 draws the air in the suction cup 307 into the cylinder 306, so that negative pressure is generated inside the suction cup 307, thereby fixing the copper strip on the multiple moving suction cups 307. 307 is fixed to the upper surface of the copper strip, and the upper surface of the copper strip is fixed to the upper surface of the copper strip.

[0056] like Figure 7 and Figure 8 As shown, a slide 303 is slidingly provided on the side of the C-shaped plate 301, and an upper L-shaped plate 305 connected to the cylinder 306 is installed on the side of the slide 303. A vertical rod 302 is installed between the inner side surfaces of the C-shaped plate 301 and passes through the slide 303. A main spring 304 is connected between the lower side of the slide 303 and the C-shaped plate 301. The descending suction cup 307 drives the slide 303 to descend through the cylinder 306 and the upper L-shaped plate 305, and the descending slide 303 compresses the main spring 304.

[0057] like Figure 7 and Figure 9 As shown, a driving mechanism 4 is also installed on the fixing mechanism 3, and the driving mechanism 4 includes a driving electric cylinder 405. A fixed base 406 is installed on the upper end of the driving electric cylinder 405. A fixed gear 407 is rotatably installed in the fixed base 406. Two fixed racks 408 engaged with the fixed gear 407 are slidably provided around the fixed gear 407. The lifting and lowering of the driving electric cylinder 405 can drive the lifting and lowering of the fixed base 406. When one fixed rack 408 moves, it will drive the other fixed rack 408 to move in the opposite direction through the fixed gear 407.

[0058] like Figure 5 and Figure 9As shown in the figure, an annular adjustment track 10 is provided around the transmission mechanism 2. On the adjustment track 10, a limiting block 402 is slidably provided on one side of each driving electric cylinder 405. An L-shaped frame 401 is installed at the end of the limiting block 402. Two limiting rods 403 extending into the upper cylinder 306 are symmetrically installed on the upper side of the L-shaped frame 401. The moving fixing mechanism 3 drives the limiting block 402 to slide on the adjustment track 10. When the piston 308 descends until it contacts the limiting rod 403, due to the limitation, the piston 308 is separated from the annular magnet 309, and the compressed auxiliary spring 310 rebounds to drive the piston 308 to restore its position.

[0059] As Figures 8 - 10 shown, a clamping groove is formed on the side surface of the upper L-shaped plate 305. One end of each fixed rack 408 is provided with a trapezoidal block 411 extending outside the driving electric cylinder 405. The trapezoidal block 411 on the same side as the clamping groove extends into the clamping groove. A return spring 410 is provided inside the fixed seat 406 on one side of one of the clamping members 409. An extrusion block 412 adapted to the trapezoidal block 411 is installed on the side surface of the L-shaped frame 401. When the fixed seat 406 descends, the inclined surface of the trapezoidal block 411 will extrude the extrusion block 412, so that the trapezoidal block 411 enters the fixed seat 406. Through the cooperation of the fixed gear 407 and the two fixed racks 408, the other trapezoidal block 411 is driven out of the clamping groove, releasing the fixation between the fixed seat 406 and the upper L-shaped plate 305.

[0060] As Figure 5 shown, two electric push rods 9 connected to the U-shaped frame 201 are symmetrically installed on the adjustment track 10. The height of the adjustment track 10 can be adjusted by the lifting and lowering of the electric push rods 9. At the same time, the lifting and lowering adjustment track 10 drives the limiting rod 403 and the extrusion block 412 to lift and lower through the L-shaped frame 401 and the limiting block 402, adjusting the descending height of the cylinder 306.

[0061] As Figure 2 、 Figure 5 and Figure 9 shown, an infrared receiver 404 is installed on the U-shaped plate 301 on one side of each driving electric cylinder 405. Two infrared transmitters 13 are symmetrically installed between the Z-shaped limiting rail 11 and the U-shaped limiting rail 12 on the upper side of the base 1. A controller is also installed on the base 1. The infrared transmitter 13 emits infrared light upward. When the infrared receiver 404 moves directly above the infrared receiver 404, it receives the infrared light and sends a signal to the controller. The controller controls the corresponding driving electric cylinder 405 of this infrared receiver 404 to shorten.

[0062] In summary, when the infrared receiver 404 moves to the top of the infrared receiver 404, it receives infrared light and sends a signal to the controller. The controller controls the driving electric cylinder 405 corresponding to the infrared receiver 404 to shorten. The shortening of the driving electric cylinder 405 drives the fixing seat 406 to descend. The descending fixing seat 406 drives the cylinder 306 and the components thereon to descend through the upper L-shaped plate 305, compressing the infrared receiver 404. At this time, the suction cup 307 is adsorbed on the copper strip, and the descending suction cup 307 drags the adsorption part of the copper strip down. When the piston 308 descends until it contacts the limit rod 403, the piston 308 is separated from the annular magnet 309 due to its limit, pressing The compressed secondary spring 310 rebounds and drives the piston 308 to restore its position, releasing the adsorption between the suction cup 307 and the copper strip. At this time, the corresponding part of the copper strip vibrates due to the release of the pull, and the aluminum material above the strip is evenly distributed through vibration. At the same time as the piston 308 separates from the annular magnet 309, the inclined surface of the trapezoidal block 411 on the fixed seat 406 squeezes the extrusion block 412, allowing the trapezoidal block 411 to enter the fixed seat 406, and the other trapezoidal block 411 is driven out of the slot through the cooperation of the fixed gear 407 and the two fixed racks 408, releasing the fixation between the fixed seat 406 and the upper L-shaped plate 305, and the main spring 304 rebounds and drives the cylinder 306 to restore its position.

[0063] During the rising process of the fixing seat 406, the upper L-shaped plate 305 will squeeze the inclined surface of the trapezoidal block 411 on the same side as it, pressing it into the fixing seat 406, and at the same time compressing the return spring 410 until the trapezoidal block 411 is aligned with the slot. The return spring 410 rebounds and drives the trapezoidal block 411 to be reinserted into the slot.

[0064] Example 2:

[0065] Based on the first embodiment, Figure 5 、 Figure 11 and Figure 12 As shown, a pushing mechanism 5 is provided on the U-shaped frame 201, and the pushing mechanism 5 includes two symmetrically arranged mounting plates 501, and a small gear 503 is rotatably installed between the two mounting plates 501. A driving rack 504 made of iron and meshing with the small gear 503 is slidingly provided on the side of the small gear 503. When the driving rack 504 descends, it can drive the small gear 503 to rotate.

[0066] like Figure 11 and Figure 12As shown, an L-shaped seat 505 is commonly installed on the sides of two mounting plates 501. An L-shaped frame 506 penetrating the L-shaped seat 505 is provided on the side of the driving rack 504. A connecting rail 507 is installed at the lower end of the L-shaped frame 506, and an electromagnet magnetically attracted to the driving rack 504 is installed at the upper end of the L-shaped frame 506. A connecting block 508 adapted to the connecting rail 507 is installed on the side of the cylinder 306. When the moving cylinder 306 drives the connecting block 508 into the connecting rail 507, the descending cylinder 306 will drive the L-shaped frame 506 to descend through the connecting rail 507 and the connecting block 508. When the electromagnet is powered on, the descending L-shaped frame 506 will drive the driving rack 504 to descend. When not powered on, the descending L-shaped frame 506 will not drive the driving rack 504 to descend.

[0067] As Figure 11 shown, a pressure plate 509 is installed on the L-shaped frame 506 above the L-shaped seat 505. A pushing spring 510 is connected between the pressure plate 509 and the L-shaped seat 505. The descending L-shaped frame 506 will press down the pushing spring 510 through the pressure plate 509. When the pushing spring 510 rebounds, it will drive the L-shaped frame 506 to return to its original position.

[0068] As Figure 12 and Figure 13 shown, a large gear 502 is installed on the side of the small gear 503. A lower gear 514 meshing with the large gear 502 is rotatably installed on the side of the mounting plate 501. The rotating small gear 503 drives the large gear 502 to rotate, and the rotating large gear 502 drives the lower gear 514 to rotate. Since the number of teeth of the large gear 502 is larger than that of the lower gear 514, the large gear 502 can drive the lower gear 514 to rotate multiple circles when it rotates one circle.

[0069] As Figure 11 shown, a push plate 513 is provided on one side of each U-shaped frame 201. A cross bar 511 is installed on the side of each mounting plate 501. A moving block 512 fixedly connected to the push plate 513 on the same side is slidably provided on the cross bar 511. The sliding push plate 513 can drive the moving block 512 to slide on the cross bar 511.

[0070] As Figure 13 shown, a circular plate 515 is installed on the side of the lower gear 514. A connecting rod 516 is rotatably installed on the side edge of the circular plate 515. An L-shaped rod 517 connected to the circular plate 515 is rotatably installed at the end of the connecting rod 516. The rotating lower gear 514 drives the circular plate 515 to rotate, and the rotating circular plate 515 drives the push plate 513 to sway left and right through the connecting rod 516 and the L-shaped rod 517, thereby pushing the aluminum liquid on the copper plate towards the center to avoid dispersion, which is suitable for the operation where the upper surface of the copper strip is not fully covered with aluminum liquid.

[0071] In summary, when the upper surface of the copper plate strip is fully covered with molten aluminum, the electromagnet is powered off, and thus the L-shaped frame 506 is not connected to the driving rack 504. When the cylinder 306 descends, the pushing mechanism 5 does not work.

[0072] When the upper surface of the copper plate strip is not fully covered with molten aluminum, the electromagnet is powered on. At this time, the L-shaped frame 506 is connected to the driving rack 504. After that, when the moving cylinder 306 allows the connecting block 508 to enter the connecting rail 507, the driving electric cylinder 405 contracts to drive the cylinder 306 to descend, pulling the copper plate strip, and at the same time driving the driving rack 504 to descend. After that, when the cylinder 306 ascends, it will also drive the driving rack 504 to ascend. The ascending driving rack 504 drives the pinion 503 to rotate. The rotating pinion 503 drives the large gear 502 to rotate. The rotating large gear 502 drives the lower gear 514 to rotate. The rotating lower gear 514 drives the circular plate 515 to rotate. The rotating circular plate 515 drives the push plate 513 to sway left and right through the connecting rod 516 and the L-shaped rod 517, so as to push the molten aluminum on the copper plate material towards the center by using the two push plates 513 to avoid dispersion.

[0073] The present invention also discloses a method for preparing and producing a solid-liquid laminated copper-aluminum composite plate strip. The steps of the method are as follows:

[0074] S1. Fix the copper plate. The conveying mechanism 2 and the fixing mechanism 3 are used to limit and fix the copper plate strip during its advancement. Specifically, the rotating conveyor belt 203 drives each suction cup 307 thereon to move along its trajectory. The cleaned and heated copper plate strip is placed on the device and advanced. Its lower surface will contact the inner suction cups 307. When the slider 312 contacts the Z-shaped limiting rail 11, it is guided by the Z-shaped limiting rail 11 to descend. Then, the descending slider 312 drives the piston 308 to descend through the lower L-shaped plate 311, compressing the auxiliary spring 310 until the piston 308 adsorbs to the annular magnet 309. At the same time, the descending piston 308 pumps the air in the suction cup 307 into the cylinder 306, generating negative pressure inside the suction cup 307, and thus fixing the copper plate strip on the multiple moving suction cups 307 to prevent the copper plate strip from shifting during the aluminum feeding process.

[0075] S2. Add aluminum material. Add semi-molten plates to fix the molten aluminum at the position where the copper plate strip is limited and fixed. Specifically, the high-temperature molten aluminum is previously put into the storage tank 602 through the input end, and then is left standing in the storage tank 602 to form a semi-molten plate solid state. Then, the discharging electric cylinder 604 extends to drive the baffle 605 to move to open the lower port of the cloth pipe 603. After that, the cloth pipe 603 in the storage tank 602 is in a flat shape through the diversion of the cloth pipe 603 and falls on the upper surface of the copper plate strip to achieve the addition of aluminum material.

[0076] S3, copper plate pulling, through the cooperation of the fixing mechanism 3 and the driving mechanism 4, the copper plate strip with aluminum material is pulled to make the corresponding part vibrate. Specifically, when the infrared receiver 404 moves to the top of the infrared receiver 404, it receives infrared light and sends a signal to the controller. The controller controls the driving electric cylinder 405 corresponding to the infrared receiver 404 to shorten. The driving electric cylinder 405 shortens and drives the fixing seat 406 to descend. The descending fixing seat 406 drives the cylinder 306 and the components thereon to descend through the upper L-shaped plate 305, compressing the infrared receiver 404. At this time, the suction cup 307 is adsorbed on the copper plate strip, and then the descending suction cup 307 pulls the adsorption part of the copper plate strip down. The piston 308 descends until it contacts the limit rod 403. Because its limit allows the piston 308 to separate from the annular magnet 309, the compressed secondary spring 310 rebounds and drives the piston 308 to restore its position, releasing the adsorption between the suction cup 307 and the copper strip. At this time, due to the release of the pull, the corresponding part of the copper strip vibrates, and the aluminum material above the strip is evenly distributed through vibration. At the same time as the piston 308 is separated from the annular magnet 309, the inclined surface of the trapezoidal block 411 on the fixed seat 406 squeezes the extrusion block 412, allowing the trapezoidal block 411 to enter the fixed seat 406, and through the cooperation of the fixed gear 407 and the two fixed racks 408, the other trapezoidal block 411 is driven to move out of the slot, releasing the fixation between the fixed seat 406 and the upper L-shaped plate 305, and the main spring 304 rebounds and drives the cylinder 306 to restore its position.

[0077] S4, re-adsorption, the copper plate strip is re-adsorbed and fixed through the geometric limit rail 12 and the fixing mechanism 3 until it moves out of the fixed range. Specifically, when the slider 312 enters the geometric limit rail 12, the slider 312 is lowered by the guidance of the geometric limit rail 12, and the copper plate strip is adsorbed by the suction cup 307. When it is about to move out of the geometric limit rail 12, the slider 312 is raised by the guidance of the geometric limit rail 12. The rising slider 312 drives the piston 308 to rise through the lower L-shaped plate 311, pushing the gas back into the suction cup 307, and releasing the fixation between the suction cup 307 and the copper plate strip.

[0078] S5. Strip casting and rolling: The copper strip with aluminum added to its upper surface is cast and rolled using the rolling mechanism 7. Specifically, two motors 702 drive two rollers 703 to rotate in opposite directions. The copper strip with aluminum added to its upper surface passes between the two rollers 703 and is cast and rolled to obtain a copper-aluminum composite strip.

[0079] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive.
