Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and in particular to an automatic welding equipment for soft copper foil. Background Art

[0002] When soldering soft copper foil, diffusion welding occupies an important position due to its unique process advantages. The core principle of this process is to promote the mutual diffusion of atoms on the surface of the metal to be welded under the synergistic effect of specific temperature and pressure, thereby forming a strong weld. Compared with traditional welding processes, diffusion welding does not require the use of solder. This feature not only simplifies the welding process and reduces production costs caused by solder procurement and processing, but also fundamentally avoids impurity contamination that may be introduced by solder and connection failure caused by solder corrosion during subsequent use. In addition, the surface of soft copper foil connections welded using diffusion welding technology is flat and smooth, with almost no obvious welding marks. This not only significantly improves the appearance quality of the product, but also reduces problems such as electric field concentration caused by welding protrusions or depressions. Therefore, diffusion welding technology has gradually become an indispensable and important means in the processing of soft copper foil connections.

[0003] However, in the practical application of existing technologies, diffusion bonding typically requires the use of a graphite mold to position and apply pressure to the soft copper foil. Because the entire welding process takes place under high temperature and pressure, adhesion between the copper foil and the graphite surface is very likely to occur after welding. This adhesion greatly increases the difficulty of unloading, severely restricting the degree of automation and production efficiency of the welding process, and also increases product defect rates and production costs. Summary of the Invention

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] An embodiment of an automated welding device for soft copper foil of the present invention is as follows Figures 1 to 12 shown.

[0021] An automated welding device for soft copper foil includes a frame 100, a welding member 200, and two clamping members 300. The welding member 200 includes an upper graphite 210 and a lower graphite 220. The upper graphite 210 is mounted on the frame 100 so as to be movable up and down and to be slidable in the horizontal direction. The sliding direction of the upper graphite 210 is referred to as the first direction. The lower graphite 220 is mounted on the frame 100 and is located below the upper graphite 210. The two clamping members 300 are arranged face to face along the first direction on the frame 100, and both abut against the upper end surface of the lower graphite 220. The soft copper foil 400 can be clamped between the two clamping members 300. In the initial state, the height of the two clamping members 300 is higher than the height of the soft copper foil 400, and both clamping members 300 can be arranged telescopically in the vertical direction.

[0022] The automated welding equipment for soft copper foil has a first state and a second state. When in the first state, the upper graphite 210 moves downward while moving in the first direction, and the upper graphite 210 moves downward to be pressed on the two clamping members 300 and compress the two clamping members 300; when in the second state, the upper graphite 210 moves upward while moving in the first direction, and the upper graphite 210 moves upward to extend the clamping members 300, and at this time the clamping members 300 can drive the soft copper foil 400 to move upward.

[0023] Specifically, a mounting platform 110 is provided on the frame 100 , and the welding piece 200 is mounted on the mounting platform 110 .

[0024] In this embodiment, the welding member 200 and the clamping member 300 are provided. When in use, the two clamping members 300 are used to clamp the soft copper foil 400 and limit the soft copper foil 400, thereby preventing the soft copper foil 400 from being offset relative to the upper graphite 210 and the lower graphite 220.

[0025] After clamping the soft copper foil 400, the upper graphite plate 210 is driven downward. At this point, the automated soft copper foil welding equipment is in the first state, with the upper graphite plate 210 moving downward and in the first direction. Because the two clamping members 300 are initially higher than the soft copper foil 400, the upper graphite plate 210 will initially come into contact with the two clamping members 300. The two clamping members 300 are gradually compressed until the upper graphite plate 210 and the soft copper foil 400 are in contact. The welding operation can then begin.

[0026] After welding is completed, the upper graphite plate 210 is moved upward. At this point, the automated copper foil welding equipment is in the second state. The upper graphite plate 210 moves upward while moving in the first direction. If adhesion occurs between the upper graphite plate 210 and the copper foil 400, the two clamping members 300 restrict the copper foil 400, preventing the copper foil 400 from moving in the first direction. This facilitates separation of the upper graphite plate 210 from the copper foil 400. Furthermore, during the upward movement of the upper graphite plate 210, the clamping members 300 return to their original position and extend. As the clamping members 300 extend, they move the copper foil 400 upward. If adhesion occurs between the lower graphite plate 220 and the copper foil 400, the clamping members 300 can be used to separate the lower graphite plate 220 from the copper foil 400. In the process of moving upward, the upper graphite 210 will also slide relative to the clamping member 300 in the first direction, so that if there is an oxide layer on the upper graphite 210, it can also be scraped off by the clamping member 300, reducing the impact of the oxide layer on the subsequent welding quality, reducing the frequency of manual cleaning of the upper graphite 210, and facilitating daily maintenance of the equipment.

[0027] The vertical movement and horizontal sliding of the upper graphite 210, along with the telescopic movement of the clamping member 300, enable seamless welding and unloading operations. From clamping and positioning the soft copper foil 400, to pressing down on the upper graphite 210 to trigger welding, to the clamping member 300 driving the soft copper foil 400 to separate and unload after welding is complete, the entire process requires virtually no human intervention. This prevents the soft copper foil 400 from adhering to the upper graphite 210 and then falling off during the upward movement of the upper graphite 210, potentially damaging the soft copper foil 400. This improves the automation and production efficiency of the soft copper foil 400 welding process.

[0028] In a further embodiment, a limit plate 120 is provided on the frame 100. The upper graphite 210 and the limit plate 120 are arranged sequentially in a second direction, which is horizontal and perpendicular to the first direction. A limit rod 211 is provided on the upper graphite 210. The limit plate 120 has a slide groove 121, which is inclined relative to the vertical direction. The limit rod 211 slidably engages with the slide groove 121, thereby enabling the upper graphite 210 to move up and down while moving in the first direction.

[0029] See also Figure 6 and Figure 7 As shown, when the upper graphite 210 moves downward, the limiting rod 211 of the upper graphite 210 will slide in the chute 121, thereby causing the upper graphite 210 to move downward and rightward. When the upper graphite 210 moves upward, the limiting rod 211 of the upper graphite 210 will slide in the chute 121, thereby causing the upper graphite 210 to move upward and leftward.

[0030] In a further embodiment, both clamping members 300 are movably disposed in the first direction.

[0031] Among them, the two clamping members 300 are installed on the mounting platform 110 of the frame 100 through the mounting frame 130. The mounting frame 130 is provided with a mounting groove 131, and the mounting groove 131 is arranged along the first direction. The two clamping members 300 are detachably installed in the mounting groove 131 by bolts 132.

[0032] In this embodiment, both clamping members 300 are movable in the first direction. When in use, the distance between the two clamping members 300 can be adjusted by the size of the soft copper foil 400 in the first direction, thereby improving the adaptability between the clamping members 300 and the soft copper foil 400.

[0033] In a further embodiment, a driving member 140 is provided on the frame 100 , and the driving member 140 is used to drive the upper graphite 210 to move up and down.

[0034] The driving member 140 includes a first hydraulic cylinder. A mounting plate 141 is provided on the output end of the first hydraulic cylinder. A sliding rod 142 is provided on the mounting plate 141 . The sliding rod 142 is arranged along a first direction and slidably cooperates with the upper graphite 210 .

[0035] When in use, the first hydraulic cylinder is activated to drive the mounting plate 141 to move up and down. The up and down movement of the mounting plate 141 will drive the upper graphite 210 to move synchronously, and the upper graphite 210 will slide in the first direction relative to the sliding rod 142.

[0036] In a further embodiment, the clamping member 300 includes an upper clamping plate 310, an adjusting member, and a lower clamping plate 320. The upper clamping plate 310 is connected to the lower clamping plate 320 via a first elastic member 330, which is arranged in the vertical direction and is a tension spring. The lower clamping plate 320 is detachably connected to the mounting frame 130 via a bolt 132. In the initial state, the first elastic member 330 causes the upper clamping plate 310 and the lower clamping plate 320 to move away from each other in the vertical direction, and downward movement of the upper clamping plate 310 relative to the lower clamping plate 320 can stretch the first elastic member 330. The adjusting member is arranged between the upper clamping plate 310 and the lower clamping plate 320. Upward movement of the upper clamping plate 310 relative to the lower clamping plate 320 can activate the adjusting member, and the activation of the adjusting member can cause the upper clamping plate 310 to drive the soft copper foil 400 upward.

[0037] The adjusting member includes a middle plate 340 and an adjusting plate 350. The upper plate 310, the middle plate 340, and the lower plate 320 are arranged in sequence in the vertical direction. The upper plate 310 passes through the middle plate 340 in the vertical direction and is connected to the lower plate 320 via a first elastic member 330. The upper plate 310 can slide in a first direction relative to the middle plate 340 and the lower plate 320. The middle plate 340 can slide up and down relative to the lower plate 320, and the adjusting plate 350 is fixedly connected to the middle plate 340. The upper plate 310 abuts against the adjusting plate 350 via a push rod 360, and a second elastic member 370 is provided between the push rod 360 and the upper plate 310. The second elastic member 370 is arranged along the first direction and is a compression spring. In the initial state, the second elastic member 370 causes the upper clamping plate 310 to abut against the middle clamping plate 340 , and the upper clamping plate 310 moves upward to compress the second elastic member 370 .

[0038] The middle plate 340 is provided with a plurality of first sliding grooves 380, which are sequentially arranged along the second direction on the middle plate 340. The lower plate 320 is provided with a plurality of second sliding grooves 390, which are sequentially arranged along the second direction on the lower plate 320. Both the first sliding grooves 380 and the second sliding grooves 390 are arranged along the first direction. A plurality of vertical rods are fixedly provided at the lower end of the upper plate 310 in the vertical direction. The plurality of vertical rods are sequentially arranged along the second direction on the upper plate 310, and the vertical rods are arranged in the vertical direction. The vertical rods, the first sliding grooves 380, and the second sliding grooves 390 are arranged in a one-to-one correspondence. The vertical rods pass through their corresponding first sliding grooves 380 and second sliding grooves 390 in the vertical direction and are connected to the lower plate 320 via the first elastic member 330. Specifically, there are three vertical rods, three first sliding grooves 380, and three second sliding grooves 390.

[0039] By providing the vertical rod, the first sliding groove 380 and the second sliding groove 390 , the upper clamping plate 310 can slide in the first direction relative to the middle clamping plate 340 and the lower clamping plate 320 .

[0040] Furthermore, the surface of the adjustment plate 350 that abuts against the top rod 360 in the first direction is a slope, and the upper and lower ends of the slope are respectively called the first end and the second end. The first end is located above the second end, and the first end is located on the side of the second end close to the upper clamping plate 310 in the first direction, so that when the upper clamping plate 310 moves upward, the second elastic member 370 will be compressed.

[0041] In this embodiment, an upper clamping plate 310, a middle clamping plate 340 and a lower clamping plate 320 are provided. After the upper graphite 210 moves downward and along the first direction until it is pressed against the two clamping members 300, the upper graphite 210 continues to move downward to stretch the first elastic member 330 through the upper clamping plate 310, so that the upper clamping plate 310 approaches the lower clamping plate 320, and the entire clamping member 300 is shortened.

[0042] At this time, the upper clamping plate 310 will drive the middle clamping plate 340 and the adjustment plate 350 to move downward synchronously until the upper graphite 210 is pressed against the soft copper foil 400. The state of the clamping member 300 after being pressed is shown in FIG. Figure 12 shown.

[0043] After the soft copper foil 400 is crimped, the soft copper foil 400 will expand in the first direction due to the pressure and its own material properties, further pressing the soft copper foil 400 against the middle clamping plate 340. Similarly, the soft copper foil 400 will also tend to be further pressed against the upper clamping plate 310, but the second elastic member 370 will be further compressed. The provision of the second elastic member 370 prevents further compression between the upper clamping plate 310 and the soft copper foil 400.

[0044] During the upward movement of the upper graphite 210, the first elastic member 330 will cause the upper clamping plate 310 to move upward relative to the lower clamping plate 320. At this time, due to the further compression between the soft copper foil 400 and the middle clamping plate 340, the middle clamping plate 340 will not move upward with the upper clamping plate 310. As the upper clamping plate 310 continues to move upward, the second elastic member 370 will be pushed and compressed by the inclined surface of the adjustment plate 350, thereby causing the upper clamping plate 310 to move in the first direction toward the side closer to the soft copper foil 400. In other words, the vertical rods on the upper clamping plate 310 slide within the corresponding first and second sliding grooves 380 and 390. It should be noted that the displacement of the upper clamping plate 310 is not large, and it only moves slightly due to the pushing action of the second elastic member 370. As the upper clamping plate 310 moves in the first direction toward the side of the soft copper foil 400, the pressure between the two increases continuously until the soft copper foil 400 is moved upward synchronously with the upper clamping plate 310 under the action of the second elastic member 370. At this point, the middle clamping plate 340 also moves synchronously with the upper clamping plate 310. During use, the force applied by the upper clamping plate 310 can be adjusted according to the degree of adhesion between the lower graphite 220 and the soft copper foil 400 to avoid excessive external force that may damage the soft copper foil 400.

[0045] Alternatively, in another possible embodiment, the adjusting member is a second hydraulic cylinder. The upper clamping plate 310 is capable of sliding relative to the lower clamping plate 320 in the first direction. The frame 100 is provided with a baffle, which is arranged in a vertical direction and has a limit slot therein. The second hydraulic cylinder slidably engages the limit slot and is arranged in the first direction. The output end of the second hydraulic cylinder is connected to the end surface of the upper clamping plate 310 in the first direction away from the soft copper foil 400.

[0046] As the upper clamping plate 310 moves downward, it drives the second hydraulic cylinder downward in tandem. After the soft copper foil 400 is crimped, the pressure and its material properties cause the soft copper foil 400 to expand in the first direction, further tightening the soft copper foil 400 against the lower clamping plate 320. Similarly, the soft copper foil 400 also tends to tighten further against the upper clamping plate 310. At this point, the output end of the second hydraulic cylinder can be used to pull the upper clamping plate 310, preventing further compression between the upper clamping plate 310 and the soft copper foil 400.

[0047] As the upper graphite 210 moves upward, the upper clamping plate 310 will drive the second hydraulic cylinder to move upward synchronously. At this time, due to the further compression of the soft copper foil 400 and the middle clamping plate 340, the lower clamping plate 320 will not move upward with the upper clamping plate 310. At this point, the second hydraulic cylinder can be used to gradually increase the pressure of the upper clamping plate 310 on the soft copper foil 400 in the first direction. The provision of a baffle will restrict the movement of the second hydraulic cylinder in the first direction away from the upper clamping plate 310. This allows the upper clamping plate 310 to move upward synchronously with the soft copper foil 400 during the upward movement of the upper graphite 210. However, the force applied by the second hydraulic cylinder in this embodiment is uncontrollable. If the applied force is too great, it may cause deformation and damage to the soft copper foil 400. Therefore, this embodiment is not considered a preferred embodiment.

[0048] In combination with the above embodiment, the specific working process is as follows: During use, the operator adjusts the distance between the two lower clamping plates 320 in the clamping member 300 in the first direction according to the size of the soft copper foil 400 , and then clamps the soft copper foil 400 between the two clamping members 300 .

[0049] Then start the first hydraulic cylinder, use the first hydraulic cylinder to drive the mounting plate 141 to move up and down, the mounting plate 141 moving up and down will drive the upper graphite 210 to move synchronously, see Figure 6 and Figure 7 As shown, when the upper graphite 210 moves downward, the limiting rod 211 of the upper graphite 210 will slide in the sliding groove 121, thereby causing the upper graphite 210 to move downward and rightward.

[0050] After the upper graphite 210 moves downward and in the first direction until it is pressed against the two clamping members 300, the upper graphite 210 continues to move downward, stretching the first elastic member 330 through the upper clamping plate 310, causing the upper clamping plate 310 to move closer to the lower clamping plate 320, shortening the entire clamping member 300. At this time, the automated welding equipment for soft copper foil is in the first state. At this time, the upper clamping plate 310 will drive the middle clamping plate 340 and the adjustment plate 350 to move downward synchronously until the upper graphite 210 is pressed against the soft copper foil 400. The state of the clamping member 300 after being pressed is shown in FIG. Figure 12 shown.

[0051] After the soft copper foil 400 is crimped, the soft copper foil 400 will expand in the first direction due to the pressure and its own material properties, further pressing the soft copper foil 400 against the middle clamping plate 340. Similarly, the soft copper foil 400 will also tend to be further pressed against the upper clamping plate 310, but the second elastic member 370 will be further compressed. The arrangement of the second elastic member 370 prevents the soft copper foil 400 from being further compressed.

[0052] During the upward movement of the upper graphite 210, the first elastic member 330 will cause the upper clamping plate 310 to move upward relative to the lower clamping plate 320. At this time, due to the further compression between the soft copper foil 400 and the middle clamping plate 340, the middle clamping plate 340 will not move upward with the upper clamping plate 310. As the upper clamping plate 310 continues to move upward, the second elastic member 370 will be pushed and compressed by the inclined surface of the adjustment plate 350, thereby causing the upper clamping plate 310 to move in the first direction toward the side closer to the soft copper foil 400. In other words, the vertical rods on the upper clamping plate 310 slide within the corresponding first and second sliding grooves 380 and 390. It should be noted that the displacement of the upper clamping plate 310 is not large, and it only moves slightly due to the pushing action of the second elastic member 370. As the upper clamping plate 310 moves in the first direction toward the side of the soft copper foil 400, the pressure between the two increases continuously until the soft copper foil 400 is moved upward synchronously with the upper clamping plate 310 under the action of the second elastic member 370. At this point, the middle clamping plate 340 also moves synchronously with the upper clamping plate 310. During use, the force applied by the upper clamping plate 310 can be adjusted according to the degree of adhesion between the lower graphite 220 and the soft copper foil 400 to avoid excessive external force that may damage the soft copper foil 400.
