Description

Technical Field

[0001] This invention belongs to the field of busbar copper busbar welding technology, specifically a busbar copper busbar welding device. Background Technology

[0002] Busbar trunking consists of a fully enclosed protective shell, high-conductivity copper busbars, temperature-resistant and flame-retardant insulating supports, and various connecting accessories. The copper busbars, as the core current-carrying conductors, often encounter 90° vertical bends when laid along vertical shafts or horizontal cable trays to avoid beams and columns or change direction. To meet space constraints and maintain electrical continuity at these bends, the straight sections of the copper busbars must be precisely cut at the bend points, and then the two ends are beveled and vertically butt-welded using specialized positioning fixtures.

[0003] Patent CN118162793B discloses a high-density busbar copper busbar welding equipment, including: a conveyor track, a side track, a pressure plate, and a welding mechanism. The welding mechanism includes a welding station, a welding frame, and a welding gun. The pressure plate positions copper busbars of different models on the conveyor track and moves the copper busbars via a conveyor belt to align the welding ends of the copper busbars. The pressure block fixes the copper busbars, preventing them from shifting during welding and improving the accuracy of the copper busbar welding. After welding, the equipment can automatically lift the copper busbars using a lifting seat and lifting head for easy removal. The entire welding process does not require manual intervention, effectively improving welding efficiency.

[0004] In the above-mentioned scheme, firstly, the copper busbar joint is divided into two sides. When welding the copper busbar, the welding gun can only weld one side of the joint at a time. Therefore, the joint needs to be flipped over for secondary welding. The flipping operation reduces the welding efficiency of the copper busbar. Secondly, the above-mentioned device can only weld one pair of copper busbars at a time. After welding, the welded copper busbar needs to be removed before the next pair of copper busbars can be welded. In this process, the removal and placement of copper busbars wastes a lot of time, further reducing the welding efficiency of the copper busbar. Therefore, the present invention provides a busbar copper busbar welding device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a busbar copper busbar welding device, which includes a frame, two sets of drive shafts symmetrically rotated and installed inside the frame, two sets of sprockets symmetrically installed on the drive shafts, the two sets of sprockets respectively meshing with two sets of chains, and several sets of feeding racks arranged between the two sets of chains. Two sets of welding mechanisms are symmetrically arranged on the frame, and two sets of feeding troughs for placing copper busbars are symmetrically arranged on the feeding racks. The welding mechanism includes a conveying mechanism, which is fixedly installed on the side of the frame, a first cylinder fixedly installed on the conveying mechanism, and a welding gun fixedly installed on the first cylinder.

[0007] By driving several sets of feeding racks to make circular motion, the feeding racks can pass sequentially through the feeding point, between the two sets of welding mechanisms, and the unloading point. During the copper busbar welding process, the copper busbar can be picked up and put down simultaneously, thereby enabling continuous welding of the copper busbar and improving the welding efficiency. Secondly, by simultaneously welding both sides of the copper busbar splice with two sets of welding guns, the welding efficiency of the copper busbar is further improved.

[0008] Preferably, the feeding rack includes a base, two sets of chains connected to both sides of the base, three sets of guide columns fixedly installed on the base, a first movable plate slidably connected to the three sets of guide columns, a second movable plate slidably connected to the three sets of guide columns, three sets of first springs set between the first and second movable plates, the three sets of first springs respectively sleeved on the three sets of guide columns, two sets of support plates symmetrically installed on the base, a fixed plate fixedly installed on the support plates, a movable clamping plate movably installed on the support plates, two sets of L-shaped rods fixedly connected to the movable clamping plate, the lower ends of the two sets of L-shaped rods fixedly connected to the second movable plate, the area enclosed by the fixed plate and the movable clamping plate is the feeding trough, two sets of guide grooves symmetrically opened on the support plate, two sets of guide rails symmetrically arranged at the lower end of the movable clamping plate, the two sets of guide rails slidably connected to the two sets of guide grooves respectively, a support plate installed in the middle of the first movable plate, a roller rotatably installed at the end of the support plate, an annular plate installed on one side of the frame, the roller rotatably connected to the annular plate, a pad strip set on the annular plate, and an inclined surface for pushing the roller at the end of the pad strip;

[0009] As the two sets of copper busbars move towards the two welding mechanisms along the feeding rack, the rollers on the feeding rack first roll along the annular plate. Then, the rollers are squeezed by the inclined surface at the end of the pad, causing the rollers to drive the support plate and the first movable plate to move towards the second movable plate. The first movable plate slides along the three sets of guide posts, and the three sets of first springs are further compressed by the first movable plate until the rollers roll onto the pad. The rebound force of the further compressed first springs increases, making the copper busbars more securely clamped between the movable clamp and the fixed plate, thus preventing incomplete welding or burn-through at the joint.

[0010] Preferably, the feeding rack also includes a lifting plate, which is movably installed in the base, a receiving block fixedly installed on the lower end face of the lifting plate, two sets of top plates symmetrically installed on the lifting plate, a second spring set in the middle of the lifting plate, two sets of through holes symmetrically opened on the lifting plate, the through holes slidingly connected to the slide rod, the slide rod fixedly installed in the base, a rectangular hole opened on the support plate, the upper end of the top plate movably inserted into the rectangular hole, a cross plate is set between the two sets of drive shafts, the drive shafts are rotatably connected to the cross plate, and a second cylinder for pushing the receiving block is fixedly installed on the cross plate;

[0011] The second cylinder is activated, and its output end pushes the receiving block and the lifting plate upward. The lifting plate slides upward along the two sets of sliding rods and compresses the second spring. At the same time, the lifting plate pushes the two sets of top plates upward. The top plates push the copper busbars upward along the rectangular holes, causing the two sets of copper busbars to detach from the discharge trough, making it easier for workers to remove the copper busbars.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. By driving several sets of feeding racks to make circular motion, the feeding racks can pass through the feeding point, between the two sets of welding mechanisms, and the unloading point in sequence. During the copper busbar welding process, the copper busbar can be picked up and put down simultaneously, thereby realizing continuous welding of the copper busbar and improving the welding efficiency of the copper busbar. Secondly, by welding both sides of the copper busbar splice at the same time by two sets of welding guns, the welding efficiency of the copper busbar is further improved.

[0014] 2. When the feeding rack is located at the feeding point, the spacing of the feeding slots is slightly less than the thickness of the copper busbar. Therefore, when the copper busbar is placed into the feeding slot, the second movable plate is first pulled towards the first movable plate, and the second movable plate slides along the three sets of guide posts, so that the three sets of first springs are compressed by the second movable plate. At the same time, the second movable plate moves the two sets of movable clamps away from the corresponding fixed plates through the four sets of L-shaped rods, so that the spacing of the feeding slots is increased, making it easier for the workers to place the copper busbar into the feeding slot.

[0015] 3. Release the second movable plate. Under the rebound force of the first spring, the movable clamp will move towards the fixed plate, clamping the copper busbar between the movable clamp and the fixed plate, thus pre-fixing the two sets of copper busbars. When the two sets of copper busbars move towards the two welding mechanisms along the feeding rack, the rollers on the feeding rack first roll along the annular plate. Then, the rollers are squeezed by the inclined surface at the end of the pad, causing the rollers to drive the support plate and the first movable plate to move towards the second movable plate. The first movable plate slides along the three sets of guide posts, and the three sets of first springs are further compressed by the first movable plate until the rollers roll onto the pads. The rebound force of the further compressed first springs increases, making the copper busbars clamped more securely between the movable clamp and the fixed plate, avoiding incomplete welding or burn-through at the splice.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] Example 1: As Figures 1 to 4 As shown in the embodiment of the present invention, a busbar copper busbar welding device includes a frame 1. Two sets of drive shafts 2 are symmetrically rotatably mounted inside the frame 1. Two sets of sprockets 3 are symmetrically mounted on the drive shafts 2. The two sets of sprockets 3 respectively mesh with two sets of chains 4. Several sets of feeding racks 5 are arranged around the two sets of chains 4. Two sets of welding mechanisms 6 are symmetrically arranged on the frame 1. Two sets of feeding grooves 51 for placing copper busbars 7 are symmetrically arranged on the feeding racks 5. The welding mechanism 6 includes a conveying mechanism 601, which is fixedly mounted on the side of the frame 1. A first cylinder 602 is fixedly mounted on the conveying mechanism 601, and a welding gun 603 is fixedly mounted on the first cylinder 602.

[0031] Specifically, the handling mechanism 601 adopts the existing ball screw structure, with... Figure 1 The middle arrow indicates the unloading point. Figure 2The middle arrow indicates the loading point. Initially, there is a set of feeding racks 5 at both the loading and unloading points. When welding of the copper busbars 7 is required, the two sets of copper busbars 7 are placed on the feeding rack 5 at the loading point, so that the two sets of copper busbars 7 are respectively located in the two sets of feeding slots 51 of the feeding rack 5. The pre-joining of the two sets of copper busbars 7 is achieved by limiting the two sets of feeding slots 51. Then, a set of drive shafts 2 are driven by a motor to rotate. The drive shafts 2 drive two sets of sprockets 3 to rotate. The two sets of sprockets 3 drive two sets of chains 4 to connect. The feeding racks 5 perform circular motion, with the direction from the loading point to the unloading point being the direction of the circular motion. This moves the two sets of copper busbars 7, which are then joined together, between the two welding mechanisms 6 along with the corresponding feeding racks 5. Simultaneously, the two sets of first cylinders 602 are activated, pushing the welding torch 603 head close to the joint of the two sets of copper busbars 7. The welding torch 603 then welds the joint. Simultaneously, the conveying mechanism 601 moves the first cylinders 602 along with the welding torch 603 along the joint, thus achieving welding of the two sets of copper busbars 7. During the welding process, two sets of copper busbars 7 can continue to be placed on the feeding rack 5 located at the loading point. After welding is completed, the welding gun 603 is withdrawn, and several sets of feeding racks 5 continue to be driven to make circular motion, so that the next set of pre-assembled two sets of copper busbars 7 can be moved between the two welding mechanisms 6. At the same time, the two sets of welded copper busbars 7 are moved to the unloading point. During the welding of copper busbars 7, the copper busbars 7 at the unloading point can be removed from the corresponding feeding rack 5 at the same time, and the two sets of copper busbars 7 to be welded can be placed on the feeding point. On the feeding rack 5, the above operation is repeated cyclically. Compared with the prior art, by driving several sets of feeding racks 5 to make circular motion, the feeding racks 5 can pass through the feeding point, between the two sets of welding mechanisms 6, and the unloading point in sequence. During the welding process of copper busbar 7, the copper busbar 7 can be picked up and put down at the same time, thereby realizing continuous welding of copper busbar 7 and improving the welding efficiency of copper busbar 7. Secondly, by simultaneously welding the two sides of the splice of copper busbar 7 with two sets of welding guns 603, the welding efficiency of copper busbar 7 is further improved.

[0032] like Figures 5 to 7As shown, the feeding rack 5 includes a base 501, with two sets of chains 4 connected to both sides of the base 501, three sets of guide posts 502 fixedly installed on the base 501, a first movable plate 503 slidably connected to the three sets of guide posts 502, a second movable plate 504 slidably connected to the three sets of guide posts 502, three sets of first springs 505 arranged between the first movable plate 503 and the second movable plate 504, the three sets of first springs 505 respectively sleeved on the three sets of guide posts 502, two sets of support plates 506 symmetrically installed on the base 501, a fixed plate 509 fixedly installed on the support plate 506, a movable clamping plate 508 movably installed on the support plate 506, two sets of L-shaped rods 507 fixedly connected to the movable clamping plate 508, and two sets of L-shaped rods 507. The lower end of the rod 507 is fixedly connected to the second movable plate 504. The area enclosed by the fixed plate 509 and the movable clamping plate 508 is the material feeding trough 51. Two sets of guide grooves 5061 are symmetrically opened on the support plate 506. Two sets of guide rails 5081 are symmetrically arranged at the lower end of the movable clamping plate 508. The two sets of guide rails 5081 are slidably connected to the two sets of guide grooves 5061 respectively. A support plate 5031 is installed in the middle of the first movable plate 503. A roller 5032 is rotatably installed at the end of the support plate 5031. An annular plate 101 is installed on one side of the frame 1. The roller 5032 is rotatably connected to the annular plate 101. A pad 102 is provided on the annular plate 101. The end of the pad 102 is provided with an inclined surface 103 for pushing the roller 5032.

[0033] Specifically, before welding the joint of the two sets of copper busbars 7, since the two sets of copper busbars 7 were not fixed, thermal stress during welding will cause the two sets of copper busbars 7 to shift, resulting in incomplete welding or burn-through at the joint, reducing the welding quality. When the feeding rack 5 is located at the feeding point, the spacing of the feeding grooves 51 is slightly smaller than the thickness of the copper busbars 7. Therefore, when the copper busbars 7 are placed into the feeding grooves 51, the second movable plate 504 is first pulled towards the first movable plate 503, and the second movable plate 504 moves along the three... The guide post 502 slides, causing the three sets of first springs 505 to be compressed by the second movable plate 504. Simultaneously, the second movable plate 504, via four sets of L-shaped rods 507, moves the two sets of movable clamping plates 508 away from the corresponding fixed plates 509, widening the gap between the feeding troughs 51. This facilitates the placement of the copper busbar 7 into the feeding trough 51 by the operator. Then, the second movable plate 504 is released. Under the rebound force of the first springs 505, the movable clamping plates 508 move towards the fixed plate 509, clamping the copper busbar 7 within the movable clamping plates 504. Between the 8 and the fixed plate 509, the two sets of copper busbars 7 are pre-fixed. When the two sets of copper busbars 7 move with the feeding rack 5 towards the two welding mechanisms 6, the rollers 5032 on the feeding rack 5 first roll along the annular plate 101. Then, the rollers 5032 are squeezed by the inclined surface 103 at the end of the pad strip 102, causing the rollers 5032 to drive the support plate 5031 together with the first movable plate 503 to move towards the second movable plate 504. The first movable plate 503 slides along the three sets of guide posts 502, and the three sets of first springs... The first spring 505 is further compressed by the first movable plate 503 until the roller 5032 rolls onto the pad 102. The rebound force of the first spring 505, which is further compressed, increases, making the copper busbar 7 more securely clamped between the movable clamping plate 508 and the fixed plate 509, thus preventing incomplete welding or burn-through at the joint. After welding is completed, the copper busbar 7 moves towards the unloading point along with the feeding rack 5. The roller 5032 on the feeding rack 5 will be offset from the pad 102, releasing the compression of the first spring 505 by the first movable plate 503.

[0034] Example 2: Figures 8 to 11As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the feeding rack 5 further includes a lifting plate 510, which is movably installed in the base 501, a receiving block 511 fixedly installed on the lower end surface of the lifting plate 510, two sets of top plates 512 symmetrically installed on the lifting plate 510, a second spring 513 set in the middle of the lifting plate 510, two sets of through holes 5101 symmetrically opened on the lifting plate 510, the through holes 5101 are slidably connected to the slide rod 5102, the slide rod 5102 is fixedly installed in the base 501, a rectangular hole 5062 is opened on the support plate 506, the upper end of the top plate 512 is movably inserted into the rectangular hole 5062, a horizontal plate 201 is provided between the two sets of transmission shafts 2, the transmission shafts 2 are rotatably connected to the horizontal plate 201, and a second cylinder 202 for pushing the receiving block 511 is fixedly installed on the horizontal plate 201.

[0035] Specifically, when the copper busbar 7 moves to the unloading point along with the feeding rack 5, the receiving block 511 is located directly above the second cylinder 202. The second cylinder 202 is activated, and the output end of the second cylinder 202 pushes the receiving block 511 and the lifting plate 510 upward. The lifting plate 510 slides upward along the two sets of sliding rods 5102 and compresses the second spring 513. At the same time, the lifting plate 510 pushes the two sets of top plates 512 upward. The top plates 512 push the copper busbar 7 upward along the rectangular hole 5062, so that the two sets of copper busbar 7 are separated from the feeding trough 51, making it easier for the workers to remove the copper busbar 7.

[0036] Working principle: Two sets of copper busbars 7 are placed on a set of feeding racks 5 located at the loading point, so that the two sets of copper busbars 7 are respectively located in the two sets of feeding slots 51 of the feeding rack 5. The two sets of feeding slots 51 limit the pre-splitting of the two sets of copper busbars 7. Then, a set of transmission shafts 2 driven by a motor rotates, which drives two sets of sprockets 3 to rotate. The two sets of sprockets 3 drive two sets of chains 4 and several sets of feeding racks 5 to make circular motion. The direction from the loading point to the unloading point is the direction of circular motion, so that the spliced ​​two sets of copper busbars 7 move with the corresponding feeding racks 5 between two sets of welding mechanisms 6. Then, two sets of first cylinders 602 are started at the same time. The first cylinders 602 push the head of the welding gun 603 close to the splicing point of the two sets of copper busbars 7, and start the welding gun 603. 03 Welding is performed at the splice joint. At the same time, the first cylinder 602 and the welding gun 603 are moved along the splice joint by the conveying mechanism 601 to weld the two sets of copper busbars 7. During this process, the two sets of copper busbars 7 can continue to be placed on the feeding rack 5 located at the feeding point. After the welding is completed, the welding gun 603 is withdrawn and several feeding racks 5 are driven to make circular motion so that the next set of two pre-spliced ​​copper busbars 7 can be moved between the two welding mechanisms 6. At the same time, the two sets of welded copper busbars 7 are moved to the unloading point. During the welding of copper busbars 7, the copper busbars 7 at the unloading point can be removed from the corresponding feeding rack 5 at the same time, and the two sets of copper busbars 7 to be welded can be placed on the feeding rack 5 located at the feeding point. The above operation is repeated in a cycle.

[0037] When the feeding rack 5 is at the feeding point, the spacing of the feeding slots 51 is slightly less than the thickness of the copper busbar 7. Therefore, when the copper busbar 7 is placed into the feeding slot 51, the second movable plate 504 is first pulled towards the first movable plate 503, and the second movable plate 504 slides along the three sets of guide posts 502, so that the three sets of first springs 505 are compressed by the second movable plate 504. At the same time, the second movable plate 504 moves the two sets of movable clamping plates 508 away from the corresponding fixed plates 509 through the four sets of L-shaped rods 507, so that the spacing of the feeding slots 51 is widened, making it easier for the operator to place the copper busbar 7 into the feeding slot 51. Then, the second movable plate 504 is released. Under the rebound force of the first springs 505, the movable clamping plates 508 will move towards the fixed plates 509, so that the copper busbar 7 is clamped in the movable clamping plates. Between plate 508 and fixed plate 509, the two sets of copper busbars 7 are pre-fixed. When the two sets of copper busbars 7 move towards the direction between the two welding mechanisms 6 along with the feeding rack 5, the roller 5032 on the feeding rack 5 first rolls along the annular plate 101. Then the roller 5032 is squeezed by the inclined surface 103 at the end of the pad 102, causing the roller 5032 to drive the support plate 5031 together with the first movable plate 503 to move towards the second movable plate 504. The first movable plate 503 slides along the three sets of guide posts 502, and the three sets of first springs 505 are further compressed by the first movable plate 503 until the roller 5032 rolls onto the pad 102. The rebound force of the further compressed first spring 505 increases, making the copper busbars 7 more stable between the movable clamping plate 508 and the fixed plate 509.

[0038] When the copper busbar 7 moves to the unloading point along with the feeding rack 5, the receiving block 511 is located directly above the second cylinder 202. The second cylinder 202 is activated, and the output end of the second cylinder 202 pushes the receiving block 511 and the lifting plate 510 upward. The lifting plate 510 slides upward along the two sets of sliding rods 5102 and compresses the second spring 513. At the same time, the lifting plate 510 pushes the two sets of top plates 512 upward. The top plates 512 push the copper busbar 7 upward along the rectangular hole 5062, so that the two sets of copper busbar 7 are separated from the feeding trough 51.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
