Description

Technical Field

[0001] This invention belongs to the field of busbar copper busbar welding technology, and in particular relates to a busbar copper busbar processing and welding equipment. Background Technology

[0002] For copper busbars, which have high thermal and electrical conductivity, the mainstream welding methods are resistance welding and arc welding, which offer better stability and efficiency. However, welding equipment rarely allows for simultaneous switching between these two welding methods. Welding copper busbars often requires adjusting the angle between the two busbars at the welding position to achieve various butt welding options. However, existing welding equipment can only handle one angle, making adjusting the angle between the two busbars relatively cumbersome. Furthermore, the busbars need to be manually positioned and aligned for welding, which is inconvenient and lacks precise angle control. Summary of the Invention

[0003] The purpose of this invention is to provide a busbar copper busbar processing and welding equipment. It uses two angle adjustment and pushing fixing units to adjust and connect two copper busbars at different angles. It can also switch between resistance welding and arc welding, solving the problems of existing welding equipment that can only perform one welding method and cannot accurately adjust multi-angle welding.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-6 The present invention is a busbar copper busbar processing and welding equipment, including a copper busbar pushing and fixing mechanism, a welding mechanism 5 and a mounting frame; The mounting frame includes a base 1, a base plate 2, and an L-shaped welding frame 11. The L-shaped welding frame 11 is provided at the corner of the upper surface of the base 1, and the crossbeam of the L-shaped welding frame 11 extends upward along the diagonal of the base 1. The upper surface of the base 1 is provided with a square groove, and the base plate 2 is fixedly clamped in the square groove. The L-shaped welding frame 11 is designed so that the welding mechanism 5 can move laterally on the frame. However, after welding is completed, it can be removed from the other side of the L-shaped welding frame 11. The base plate 2 is separated from the base 1 so that the structure on the base plate 2 can be independently cut or cast.

[0027] The copper busbar pushing and fixing mechanism includes two angle-adjustable pushing and fixing units 3. Two arc-shaped notches 21 are symmetrically arranged on the base plate 2 along the diagonal of the base plate 2. One end of the angle-adjustable pushing and fixing unit 3 is rotatably set at the inner port position of the arc-shaped notch 21. A rotation drive component is provided at the bottom of the angle-adjustable pushing and fixing unit 3. The rotation drive component is used to drive the angle-adjustable pushing and fixing unit 3 to rotate along the end to realize the angle adjustment between the two angle-adjustable pushing and fixing units 3. The arc-shaped notch 21 houses the angle adjustment and pushing fixing unit 3. This unit can rotate within the notch 21, allowing for adjustable copper busbar feeding direction and ensuring the two busbars can be joined at the required angle. The two busbars will then connect at the welding point on the lower electrode structure 4.

[0028] The base plate 2 has a lower electrode structure 4 located between two arc-shaped notches 21. The lower surface of the crossbeam of the L-shaped welding frame 11 is provided with a transverse movement mechanism. The welding mechanism 5 includes a transverse movement block 50, a resistance welding unit 52, and an arc welding unit 51. The transverse movement block 50 is mounted on the transverse movement mechanism. The resistance welding unit 52 and the arc welding unit 51 are mounted at the bottom of the transverse movement block 50. A CCD high-definition camera 53 is mounted between the resistance welding unit 52 and the arc welding unit 51.

[0029] The lower electrode structure 4 is mainly used for resistance welding. The CCD high-definition camera 53 scans back and forth to photograph the copper busbar to determine the gap position or the position of the superimposed copper busbar (used for resistance welding).

[0030] like Figure 6 The transverse mechanism consists of two limit slides, a transverse servo motor, and a transverse lead screw. The transverse block 50 is fitted onto the limit slides, and the transverse servo motor drives the transverse lead screw to move the transverse block 50.

[0031] Both the resistance welding unit 52 and the arc welding unit 51 must first use a CCD high-definition camera 53 to scan back and forth to determine the welding position before performing the corresponding electric welding.

[0032] The angle adjustment and pushing fixing unit 3 includes a U-shaped slide 31, a metal push plate 32, a centering clamping unit, and a copper busbar pressing and pushing unit 33; The upper surface of the U-shaped slide 31 is provided with two rows of limiting round holes. A micro-lift motor is embedded in the middle of the upper surface of the U-shaped slide 31. A fine-adjustment threaded rod is connected to the rotating shaft of the micro-lift motor. The bottom of the metal push plate 32 is provided with a limiting post 321 that matches the limiting round holes. The fine-adjustment threaded rod is spirally inserted into the metal push plate 32. Centered clamping units are distributed on both sides of the metal push plate 32. like Figure 3 and 4 The U-shaped slide 31 can restrict the mounting of the metal push plate 32. The metal push plate 32 can only move up and down (range 0-8mm, copper busbar thickness should not exceed 7mm). When the metal push plate 32 moves up and down, it will not shake because the limiting post 321 is inside the limiting hole.

[0033] The centering clamping unit can simultaneously push the copper busbar from both sides to center it, so that the end of the copper busbar (welding end) can be accurately moved to a fixed position.

[0034] The top of the side rails of the U-shaped slide 31 are symmetrically provided with two rows of copper busbar pressing and pushing units 33. The copper busbar pressing and pushing units 33 can rotate to the top of the metal push plate 32 and press on the copper busbar. All the copper busbar pressing and pushing units 33 can synchronously push the copper busbar forward.

[0035] The two rows of copper busbar pressing and pushing units 33 are rotatable. When pressing and pushing are not required, they are located above the top of the side flanges of the U-shaped slide 31. When pressing and pushing are required, they rotate to the top of the copper busbars inside the U-shaped slide 31 for pushing. After welding is completed, the copper busbar pressing and pushing units 33 rotate to the top of the side flanges of the U-shaped slide 31 to remove the copper busbars.

[0036] The centering clamping unit includes a side-rotating servo motor 341 and a push rod 34. One end of the push rod 34 is fixedly sleeved on the rotating shaft of the side-rotating servo motor 341, and the other end is a semi-circular end. The metal push plate 32 has two rows of square extension plates on both sides that are inserted into the U-shaped slide rail 31, and the side rotation servo motor 341 is embedded in the square extension plate. All of the aforementioned side-rotation servo motors 341 can synchronously push the push rod 34 to rotate toward the middle position of the metal push plate 32.

[0037] The side-rotating servo motor 341 pushes the push rod 34 outward (rotates outward) against the side of the copper busbar. The two rows of push rods 34 will rotate at the same angle, so that the copper busbar is centered. The end of the push rod 34 is semi-circular, which can achieve better fit with the copper busbar at the edge of the circle.

[0038] The copper busbar pressing and pushing unit 33 includes a steering servo motor 330, a pressing frame 331, a pressing column 332, a pushing cylinder 333, a micro servo motor 334, and a pushing roller 336. Two rows of mounting columns are provided on the top of the side walls of the U-shaped slide rail 31. The steering servo motor 330 is embedded in the top of the mounting columns. A rotating rod is provided on the side wall at the middle position of the pressing frame 331. The end of the rotating rod is fixedly sleeved on the rotating shaft of the steering servo motor 330. The top of the pressing column 332 is movably inserted from the bottom of the pressing frame 331. A downward-facing pushing cylinder 333 is fixed on the top of the pressing frame 331. The telescopic shaft of the pushing cylinder 333 is fixed on the top of the pressing column 332. A pushing roller 336 is rotatably provided at the bottom of the pressing column 332. The micro servo motor 334 is embedded in the bottom of the pressing column 332. The micro servo motor 334 and the pushing roller 336 are connected by a drive belt 335.

[0039] like Figure 3 and 4 As shown, when no pressure is applied, the position of the copper busbar pressing and pushing unit 33 is... Figure 3 As shown on the left, when it is necessary to push the copper busbar against the pressure, as... Figure 3As shown on the right, during the pressing and pushing process, the downward-pushing cylinder 333 pushes the downward-pressing column 332 down within the downward-pressing frame 331, causing the forward-pushing roller 336 to contact the copper busbar. The micro servo motor 334 drives the forward-pushing roller 336 to rotate. The forward-pushing roller 336 is a rubber roller, which has high friction with the copper busbar. The surface of the copper busbar and the surface of the metal push plate 32 are smooth, allowing for smooth sliding during the pushing process. In addition, multiple forward-pushing rollers 336 are in contact and pushing, enabling multi-point displacement of the copper busbar. When the set welding position is reached (the CCD high-definition camera 53 takes a picture to see if the position has been reached, and then corrects it back and forth), one copper busbar reaches the position first, and the other is spliced ​​into the position. When the pushing is completed, the pushing stops, and after the welding is completed, all copper busbar pressing and pushing units 33 are rotated back to the initial position.

[0040] The inner end of the arc-shaped notch 21 is a circular arc sidewall 211, the front end of the U-shaped slide 31 is semi-circular, the front end of the metal push plate 32 is provided with an arc-shaped edge that matches the front end of the U-shaped slide 31, the bottom of the front end of the U-shaped slide 31 is provided with a rotating shaft, a bearing is sleeved on the rotating shaft and the bearing is embedded in the arc-shaped notch 21, and the semi-circular edge of the front end of the U-shaped slide 31 can fit and rotate along the circular arc sidewall 211 of the arc-shaped notch 21; The included angle between the center lines of the two U-shaped slides 31 is 60-180°.

[0041] The U-shaped slide 31 and the front end of the metal push plate 32 are matched and rotate along the arc side wall 211. Even if the metal push plate 32 moves upward, the lower surface of the metal push plate 32 will not be higher than the base plate 2 because the thickness of the metal push plate 32 is greater than the maximum upward movement height of the metal push plate 32 (the thickness of the metal push plate 32 is 10mm). This allows the included angle between the two copper busbars to be 60° to be on the same straight line.

[0042] When the lower surface of the metal push plate 32 is attached to the upper surface of the U-shaped slide 31, the upper surface of the metal push plate 32 and the upper surface of the base plate 2 are on the same horizontal plane. The rotary drive assembly includes an angle servo motor and a displacement gear disk. The bottom wall of the arc-shaped notch 21 is provided with an arc-shaped groove 22 with the rotation axis as the center. The inner wall of the arc-shaped groove 22 is provided with an arc-shaped toothed belt 221. The angle servo motor is embedded in the bottom wall of the U-shaped slide 31. The rotation shaft of the angle servo motor is fitted with a displacement gear disk, and the displacement gear disk meshes with the arc-shaped toothed belt 221.

[0043] Each time the angle is adjusted, the U-shaped slide rail 31 is first pushed to the edge position. At this time, the angle servo motor is started to drive the displacement gear disk to rotate a certain number of times to achieve the rotation angle adjustment. Thus, the required angle can be accurately adjusted each time the angle is adjusted. After the angle is determined, the copper busbar is pushed.

[0044] The lower electrode structure 4 includes a lower electrode plate 41 and two comb-shaped plates 42. The lower electrode plate 41 is embedded in the base plate 2. The comb-shaped plates 42 are inserted into the base plate 2 on both sides of the lower electrode plate 41. The bottom of the comb-shaped plates 42 can move through the base 1. An upward push cylinder 43 is installed at the bottom of the base 1. The telescopic shaft of the upward push cylinder 43 is connected to the bottom of the comb-shaped plates 42 through a push plate.

[0045] The two comb-shaped plates 42 are used during resistance welding. When one copper busbar needs to be supported on the ground at its end, the other comb-shaped plate 42 is slightly raised. When the copper busbar is pushed onto and pressed against the comb-shaped plate 42, the end of the copper busbar is positioned just above the lower electrode plate 41. Before pushing the other copper busbar, the metal push plate 32 is moved upward by 1-2 mm above the thickness of one copper busbar. When the copper busbar is pushed out, it will shift to be above the other copper busbar (the copper busbar will not sag over a short distance while suspended). During resistance welding, the upper electrode moves down and presses against the copper busbar to conduct current welding on the overlapping copper busbars. Because the end of the copper busbar is on the lower electrode plate 41 and does not span across the lower electrode plate 41, it is easy to press it against the lower electrode plate 41 during downward pressure, ensuring normal power supply.

[0046] As the CCD high-definition camera 53 moves back and forth above the lower electrode plate 41, it takes real-time pictures of the position of the lower copper busbar end to determine whether the copper busbar end is placed accurately.

[0047] Taking photos of the copper busbar back and forth, and determining the position of the copper busbar based on the camera position and the photos (using the two rows of toothed protrusions of the comb plate 42 as a standard reference) can accurately determine the position.

[0048] The resistance welding unit 52 includes an upper electrode block 523, an electrode mounting block 522, a first pressing column 521, a fine-tuning servo motor 525, and two horizontal limiting slide rods 524. The front half of the bottom of the transverse block 50 is provided with a first square groove. A first pressing motor is embedded in the top of the first square groove. A first pressing screw is connected to the shaft of the first pressing motor. The top of the first pressing column is movably inserted into the first square groove and the pressing screw is spirally passed through the first pressing column 521. The bottom of the first pressing column 521 is provided with a movable groove. Two horizontal limiting slide rods 524 are inserted into the side wall of the movable groove. The electrode mounting block 522 is movably sleeved on the two horizontal limiting slide rods 524. The fine-tuning servo motor 525 is embedded in the side wall of the movable groove. An adjustment screw is connected to the shaft of the fine-tuning servo motor 525. The adjustment screw spirally passes through the electrode mounting block 522. The upper electrode block 523 is embedded in the bottom of the electrode mounting block 522.

[0049] like Figure 6As shown, if the upper electrode block 523 cannot move slightly left or right, there may be misalignment or positional deviation when the copper busbars are stacked, making it impossible to press it onto the end of the copper busbars effectively. The electrode mounting block 522 can be used to adjust the position by moving the two horizontal limit sliders 524 slightly left or right. The fine-tuning servo motor 525 is used to fine-tune the position of the electrode mounting block 522. Under the drive of the first pressing column by the first pressing motor, the upper electrode block 523 is pressed down onto the stacked copper busbars.

[0050] The rear half of the bottom of the transverse block 50 is provided with a second square groove. A second pressing motor is embedded in the top of the second square groove. A second pressing screw is connected to the shaft of the second pressing motor. The arc welding unit 51 includes a second pressing column 511, a universal robotic arm 512 and an arc welding head 513. The second pressing column 511 is movably inserted from the bottom of the second square groove and the second pressing screw is spirally inserted into the second pressing column 511. The bottom of the second pressing column 511 is provided with a universal robotic arm 512. The arc welding head 513 is fixed to the control end of the universal robotic arm 512.

[0051] Similarly, the downward movement of the second pressure column 511 is achieved by the rotation of the second downward pressure motor, which drives the second downward pressure screw to push the second pressure column 511 downward. When the column is moved to the height suitable for arc welding, the angle of the arc welding head 513 is adjusted using the universal robotic arm 512, and the arc welding head 513 is moved laterally to the welding joint via the lateral movement block 50. The universal robotic arm 512 has three sections: the top section is a rotating shaft, the middle section swings left and right at the bottom of the rotating shaft (in relative directions), and the bottom section swings back and forth at the bottom of the middle rod. That is, the swinging of the middle rod and the bottom rod are perpendicular to each other.
