TECHNICAL FIELD

[0001] The present application relates to the technical field of welding equipment, in particular to an automatic welding equipment for soft copper foil. BACKGROUND

[0002] In the process of welding 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 action of a specific temperature and pressure, thereby forming a firm 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 due to solder procurement and handling, but also fundamentally avoids the problem of impurity pollution caused by solder and the connection failure caused by solder corrosion during subsequent use. In addition, the use of diffusion welding technology to weld soft copper foil connections results in a smooth and flat surface with almost no visible 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 actual application process of the prior art, diffusion welding usually requires the use of graphite molds to position and press the soft copper foil. Since the entire welding process is carried out in a high-temperature and high-pressure welding environment, the contact surface between the soft copper foil and the graphite after welding is prone to sticking. The sticking between the two greatly increases the difficulty of the operation in the unloading process, severely restricts the degree of automation and production efficiency of the welding process, and also increases the product failure rate and production cost.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the protection scope of the present application.

[0031] An embodiment of the automatic soft copper foil welding device is shown in Figures 1 to 12 .

[0032] The automatic soft copper foil welding device comprises a rack 100, a welding member 200 and two clamping members 300. The welding member 200 comprises an upper graphite 210 and a lower graphite 220. The upper graphite 210 is movably installed on the rack 100 in a vertical direction and is slidably installed on the rack 100 in a horizontal direction. The sliding direction of the upper graphite 210 is referred to as a first direction. The lower graphite 220 is installed on the rack 100 and is located below the upper graphite 210. The two clamping members 300 are arranged face to face on the rack 100 in the first direction and are in abutment with the upper end surface of the lower graphite 220. The soft copper foil 400 can be clamped between the two clamping members 300. In an initial state, the height of the two clamping members 300 is higher than the height of the soft copper foil 400, and the two clamping members 300 are arranged to be vertically telescopic.

[0033] The automatic soft copper foil welding device has a first state and a second state. In the first state, the upper graphite 210 moves downward and in the first direction, and the downward movement of the upper graphite 210 can press and compress the two clamping members 300. In the second state, the upper graphite 210 moves upward and in the first direction, and the upward movement of the upper graphite 210 can elongate the clamping members 300, and at this time, the clamping members 300 can drive the soft copper foil 400 to move upward.

[0034] Specifically, the rack 100 is provided with a mounting platform 110, and the welding member 200 is installed on the mounting platform 110.

[0035] In use, the two clamping members 300 clamp the soft copper foil 400, limit the soft copper foil 400, and prevent the soft copper foil 400 from relatively deviating from the upper graphite 210 and the lower graphite 220.

[0036] After the soft copper foil 400 is clamped, the upper graphite 210 is driven to move downward, and the soft copper foil automatic welding device is in the first state. The upper graphite 210 moves downward along the first direction. Since the height of the two clamping pieces 300 is higher than the height of the soft copper foil 400 in the initial state, the upper graphite 210 will be pressed with the two clamping pieces 300 first. The two clamping pieces 300 are gradually compressed and shortened until the upper graphite 210 is pressed with the soft copper foil 400. Then the welding operation can be started.

[0037] After the welding is completed, the upper graphite 210 is moved upward, and the soft copper foil automatic welding device is in the second state. The upper graphite 210 moves upward along the first direction. If the upper graphite 210 and the soft copper foil 400 are adhered, the soft copper foil 400 cannot move in the first direction due to the limitation of the two clamping pieces 300, so that the upper graphite 210 and the soft copper foil 400 are separated. During the upward movement of the upper graphite 210, the clamping piece 300 is reset to be elongated. During the elongation of the clamping piece 300, the clamping piece 300 drives the soft copper foil 400 to move upward. If the lower graphite 220 and the soft copper foil 400 are adhered, the clamping piece 300 can separate the lower graphite 220 and the soft copper foil 400. During the upward movement of the upper graphite 210, the upper graphite 210 also slides relative to the clamping piece 300 in the first direction, so that the oxidation layer on the upper graphite 210 can also be scraped off by the clamping piece 300, reducing the influence of the oxidation layer on the subsequent welding quality, reducing the frequency of manual cleaning of the upper graphite 210, and facilitating the daily maintenance of the equipment.

[0038] The upward and downward movement and horizontal sliding of the upper graphite 210 and the extension and retraction of the clamping piece 300 realize the continuous operation of welding and unloading. From the clamping and positioning of the soft copper foil 400 to the downward pressing of the upper graphite 210 to trigger welding, and then to the separation and unloading of the soft copper foil 400 driven by the clamping piece 300 after the welding is completed, the whole process basically does not need manual intervention for separation, and it can prevent the soft copper foil 400 from being adhered to the upper graphite 210 when the soft copper foil 400 is adhered to the upper graphite 210, and then moving with the upper graphite 210 during the upward movement of the upper graphite 210, and then falling to cause damage to the soft copper foil 400, thereby improving the automation degree and production efficiency of the soft copper foil 400 welding.

[0039] In a further embodiment, a limiting plate 120 is arranged on the rack 100, and the upper graphite 210 and the limiting plate 120 are arranged in sequence in the second direction. The second direction is horizontal and perpendicular to the first direction. The upper graphite 210 is provided with a limiting rod 211, and the limiting plate 120 is provided with a sliding groove 121. The sliding groove 121 is arranged obliquely relative to the vertical direction. The limiting rod 211 and the sliding groove 121 are in sliding cooperation, so that the upper graphite 210 can move upward and downward while moving along the first direction.

[0040] Referring toFigure 6 and Figure 7 As shown in FIG. 10, when the upper graphite 210 moves downward, the limiting rod 211 of the upper graphite 210 will slide in the sliding groove 121, and then the upper graphite 210 moves downward and rightward. When the upper graphite 210 moves upward, the limiting rod 211 of the upper graphite 210 will slide in the sliding groove 121, and then the upper graphite 210 moves upward and leftward.

[0041] In a further embodiment, both clamping pieces 300 are movably arranged in the first direction.

[0042] Both clamping pieces 300 are mounted on the mounting platform 110 of the rack 100 through the mounting frame 130, the mounting frame 130 is provided with a mounting groove 131 in the first direction, and both clamping pieces 300 are detachably mounted in the mounting groove 131 through the bolts 132.

[0043] In the embodiment, both clamping pieces 300 are movable in the first direction, and the distance between the two clamping pieces 300 can be adjusted in the first direction by the soft copper foil 400 in use, so that the fitting degree of the clamping piece 300 and the soft copper foil 400 is improved.

[0044] In a further embodiment, the rack 100 is provided with a driving piece 140, and the driving piece 140 is used to drive the upper graphite 210 to move upward and downward.

[0045] The driving piece 140 comprises a first hydraulic cylinder, and the output end of the first hydraulic cylinder is provided with a mounting plate 141, the mounting plate 141 is provided with a sliding rod 142, the sliding rod 142 is arranged in the first direction and is in sliding cooperation with the upper graphite 210.

[0046] In use, the first hydraulic cylinder is started to drive the mounting plate 141 to move upward and downward, the mounting plate 141 moves upward and downward to drive the upper graphite 210 to move synchronously, and the upper graphite 210 slides in the first direction relative to the sliding rod 142.

[0047] In a further embodiment, the clamping piece 300 comprises an upper clamping plate 310, an adjusting piece and a lower clamping plate 320. The upper clamping plate 310 is connected with the lower clamping plate 320 through a first elastic piece 330, the first elastic piece 330 is arranged in the vertical direction, and the first elastic piece 330 is a tension spring. The lower clamping plate 320 is detachably connected with the mounting frame 130 through the bolts 132. In the initial state, the first elastic piece 330 makes the upper clamping plate 310 and the lower clamping plate 320 move away from each other in the vertical direction, and the upward movement of the upper clamping plate 310 relative to the lower clamping plate 320 can stretch the first elastic piece 330. The adjusting piece is arranged between the upper clamping plate 310 and the lower clamping plate 320. The upward movement of the upper clamping plate 310 relative to the lower clamping plate 320 can make the adjusting piece act, and the action of the adjusting piece can drive the upper clamping plate 310 to move upward with the soft copper foil 400.

[0048] The adjusting member comprises the middle clamping plate 340 and the adjusting plate 350, the upper clamping plate 310, the middle clamping plate 340 and the lower clamping plate 320 are sequentially arranged in the vertical direction, the upper clamping plate 310 passes through the middle clamping plate 340 in the vertical direction and is connected with the lower clamping plate 320 through the first elastic member 330. And the upper clamping plate 310 can slide in the first direction relative to the middle clamping plate 340 and the lower clamping plate 320. The middle clamping plate 340 can slide up and down relative to the lower clamping plate 320, and the adjusting plate 350 is fixedly connected with the middle clamping plate 340. The upper clamping plate 310 abuts against the adjusting plate 350 through the top rod 360, and the second elastic member 370 is arranged between the top rod 360 and the upper clamping plate 310, the second elastic member 370 is arranged in the first direction, and the second elastic member 370 is a compression spring. In the initial state, the second elastic member 370 abuts against the upper clamping plate 310 and the middle clamping plate 340, and the upward movement of the upper clamping plate 310 can compress the second elastic member 370.

[0049] The middle clamping plate 340 is provided with a plurality of first sliding grooves 380 arranged in the second direction, and the lower clamping plate 320 is provided with a plurality of second sliding grooves 390 arranged in the second direction, the first sliding grooves 380 and the second sliding grooves 390 are arranged in the first direction, the lower end of the upper clamping plate 310 is fixedly provided with a plurality of vertical rods arranged in the vertical direction and arranged in the second direction on the upper clamping 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 correspondingly arranged, and the vertical rods pass through the first sliding grooves 380 and the second sliding grooves 390 arranged correspondingly in the vertical direction and are connected with the lower clamping plate 320 through the first elastic member 330. Specifically, the vertical rods, the first sliding grooves 380 and the second sliding grooves 390 are all provided with three.

[0050] By arranging the vertical rods, the first sliding grooves 380 and the second sliding grooves 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.

[0051] Further, the surface of the adjusting plate 350 abutting against the top rod 360 in the first direction is an inclined surface, the upper and lower ends of the inclined surface are respectively referred to as a first end and a 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.

[0052] The upper clamping plate 310, the middle clamping plate 340 and the lower clamping plate 320 are arranged, and the upper graphite 210 is continuously moved downward along the first direction to be pressure-bonded with the two clamping members 300, and then the upper graphite 210 continuously moves downward to stretch the first elastic member 330 through the upper clamping plate 310, so that the upper clamping plate 310 is close to the lower clamping plate 320, and the whole clamping member 300 is shortened.

[0053] At this time, the upper clamping plate 310 drives the middle clamping plate 340 and the adjusting plate 350 to move downward synchronously until the upper graphite 210 is pressure-bonded with the soft copper foil 400, and the state of the pressure-bonded clamping member 300 is shown in FIG. 4. Figure 12

[0054] After the pressure-bonding of the soft copper foil 400 is completed, the size of the soft copper foil 400 in the first direction is increased due to the pressure and the material characteristics of the soft copper foil 400, so that the soft copper foil 400 is further pressed with the middle clamping plate 340. Similarly, the soft copper foil 400 also has a tendency to be further pressed with the upper clamping plate 310, but the second elastic member 370 is further compressed, and the arrangement of the second elastic member 370 makes the upper clamping plate 310 and the soft copper foil 400 not be further pressed.

[0055] In the process of moving upward of the upper graphite 210, the first elastic member 330 promotes the upper clamping plate 310 to move upward relative to the lower clamping plate 320, and at this time, the middle clamping plate 340 does not move upward with the upper clamping plate 310 due to the further pressing of the soft copper foil 400 with the middle clamping plate 340. In the process of continuously moving upward of the upper clamping plate 310, the second elastic member 370 is continuously compressed by the slope on the adjusting plate 350, so that the upper clamping plate 310 moves in the first direction to the side close to the soft copper foil 400, that is, the vertical rod on the upper clamping plate 310 slides in the first sliding groove 380 and the second sliding groove 390 corresponding to the arrangement, and it should be particularly noted that the displacement of the upper clamping plate 310 is not large, and only slightly moves under the pushing action of the second elastic member 370. The movement of the upper clamping plate 310 in the first direction to the side close to the soft copper foil 400 increases the pressure between the two, until the soft copper foil 400 is driven by the upper clamping plate 310 to move upward synchronously under the action of the second elastic member 370, and at this time, the middle clamping plate 340 also moves upward synchronously with the upper clamping plate 310. In use, the force of the upper clamping plate 310 can be adjusted according to the degree of adhesion of the lower graphite 220 and the soft copper foil 400 to avoid excessive external force applied by artificial to cause damage to the soft copper foil 400.

[0056] ​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. A baffle is arranged on the frame 100, the baffle is arranged in the vertical direction, a limiting slot is formed in the baffle, the limiting slot is arranged in the vertical direction, the second hydraulic cylinder is in sliding fit with the limiting slot, and the second hydraulic cylinder is arranged in the first direction. The output end of the second hydraulic cylinder is connected with the end face of the upper clamping plate 310 on the side away from the soft copper foil 400 in the first direction.

[0057] When the upper clamping plate 310 moves downward, the upper clamping plate 310 will drive the second hydraulic cylinder to move downward synchronously. After the crimping of the soft copper foil 400 is completed, due to the influence of the pressure and the material properties of the soft copper foil 400, the size of the soft copper foil 400 in the first direction will increase, thereby making the soft copper foil 400 and the lower clamping plate 320 further compressed. Similarly, the soft copper foil 400 also has a tendency to be further compressed with the upper clamping plate 310, at this time the output end of the second hydraulic cylinder can be used to pull the upper clamping plate 310, so that the upper clamping plate 310 and the soft copper foil 400 are not further compressed.

[0058] When the upper graphite 210 moves upward, the upper clamping plate 310 will drive the second hydraulic cylinder to move upward synchronously, at this time the lower clamping plate 320 will not move upward with the upper clamping plate 310 because the soft copper foil 400 and the middle clamping plate 340 are further compressed. At this time, 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 arrangement of the baffle will limit the movement of the cylinder body of the second hydraulic cylinder in the first direction away from the upper clamping plate 310, thereby enabling the upper clamping plate 310 to drive the soft copper foil 400 to move upward synchronously when the upper clamping plate 310 moves upward during the upward movement of the upper graphite 210. However, the force exerted by the second hydraulic cylinder in this embodiment is uncontrollable, and if the force is too large, it may cause the soft copper foil 400 to deform and damage. This embodiment is not used as a preferred embodiment.

[0059] In combination with the above embodiment, the specific working process is as follows:

[0060] In use, an operator adjusts the distance between the two lower clamping plates 320 in the first direction in the clamping member 300 according to the size of the soft copper foil 400, and then clamps the soft copper foil 400 between the two clamping members 300.

[0061] Then the first hydraulic cylinder is started, and the first hydraulic cylinder drives the mounting plate 141 to move up and down, which drives the upper graphite 210 to move synchronously. As shown in Figure 6 and Figure 7 When the upper graphite 210 moves downward, the limiting rod 211 of the upper graphite 210 will slide in the sliding groove 121, thereby enabling the upper graphite 210 to move downward and rightward.

[0062] After the upper graphite 210 moves along the first direction and is pressed against the two clamping members 300, the upper graphite 210 continues to move downward, which stretches the first elastic member 330 through the upper clamping plate 310, and makes the upper clamping plate 310 close to the lower clamping plate 320, and the whole clamping member 300 is shortened. At this time, the automatic welding equipment for the soft copper foil is in the first state. At this time, the upper clamping plate 310 drives the middle clamping plate 340 and the adjusting 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 Figure 12

[0063] After the pressing of the soft copper foil 400 is completed, the size of the soft copper foil 400 in the first direction will be increased due to the pressure and the material characteristics of the soft copper foil 400, which further presses the soft copper foil 400 against the middle clamping plate 340. Similarly, the soft copper foil 400 also has a tendency 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 makes the soft copper foil 400 not be further pressed.

[0064] During the upward movement of the upper graphite 210, the first elastic member 330 will promote the upward movement of the upper clamping plate 310 relative to the lower clamping plate 320. At this time, the middle clamping plate 340 will not move upward with the upper clamping plate 310 because the soft copper foil 400 is further pressed against the middle clamping plate 340. During the continuous upward movement of the upper clamping plate 310, the second elastic member 370 will be continuously compressed by the slope on the adjusting plate 350, which further promotes the movement of the upper clamping plate 310 in the first direction to the side close to the soft copper foil 400, that is, the vertical rod on the upper clamping plate 310 slides in the first sliding groove 380 and the second sliding groove 390 arranged correspondingly. It should be particularly noted that the displacement of the upper clamping plate 310 is not large, but only slightly moves under the pushing action of the second elastic member 370. The movement of the upper clamping plate 310 in the first direction to the side close to the soft copper foil 400 will continuously increase the pressure between the two, until the soft copper foil 400 can be driven to move upward synchronously with the upper clamping plate 310 under the action of the second elastic member 370, and at this time, the middle clamping plate 340 will also move upward synchronously with the upper clamping plate 310. In use, the force of the upper clamping plate 310 can be adjusted according to the degree of adhesion of the lower graphite 220 to the soft copper foil 400, so as to avoid excessive external force applied manually and damage to the soft copper foil 400.

[0065] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.​
