Description

Technical Field

[0001] The invention belongs to the technical field of busbar copper bar welding, in particular to a busbar copper bar welding device. Background Art

[0002] Busbar ducts consist of a fully enclosed protective casing, highly conductive copper busbars, heat-resistant and flame-retardant insulating brackets, and various connection accessories. The copper busbars, serving as the core current-carrying conductors, often encounter 90° vertical bends when laid along vertical shafts or horizontal bridges to avoid beams and columns and change their orientation. To meet spatial constraints and maintain electrical continuity at corners, the straight section of the busbar must be precisely cut at the bend. The two ends are then beveled and vertically butt-welded using specialized positioning fixtures.

[0003] The patent with announcement number CN217586128U discloses a dense busbar copper busbar welding equipment, including: a conveyor track, a side track, a pressure plate, and a welding mechanism. The welding mechanism includes a soldering table, a welding frame, and a welding gun. The pressure plate realizes the positioning of different types of copper buses on the conveyor track, and moves the copper buses through the conveyor belt to align the welding ends of the copper buses, and fixes the copper buses through the pressure block so that the copper buses will not move during welding by the welding gun, thereby improving the accuracy of copper busbar welding; and after welding is completed, the equipment can automatically lift the copper busbar using a lifting seat and a lifting head for easy removal. The entire welding process does not require manual participation, effectively improving the efficiency of welding.

[0004] In the above scheme, first, the copper busbar joint is divided into two sides. When welding the copper busbar, the welding gun can only weld one side of the copper busbar joint at a time. Therefore, the copper busbar joint needs to be turned over for a second welding. The turning operation reduces the welding efficiency of the copper busbar. Secondly, the above device can only weld a pair of copper buses at a time. After welding, the welded copper buses need to be removed before the next group of copper buses can be welded. In this process, a lot of time is wasted in taking and placing the copper buses, which further reduces the welding efficiency of the copper buses. For this reason, the present invention provides a busbar duct copper busbar welding device. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: a busbar copper bar welding device described in the present invention includes a frame, two sets of transmission shafts are symmetrically mounted in the frame for rotation, two sets of sprockets are symmetrically mounted on the transmission shafts, the two sets of sprockets respectively mesh with two sets of chains, and surround a plurality of unloading racks arranged between the two sets of chains, two sets of welding mechanisms are symmetrically arranged on the frame, two sets of unloading troughs for placing copper bars are symmetrically arranged on the unloading racks, the welding mechanism includes a conveying mechanism fixedly mounted on a side of the frame, a first cylinder fixedly mounted on the conveying mechanism, and a welding gun fixedly mounted on the first cylinder; By driving several groups of unloading racks to make circular motion, the unloading racks can pass through the loading point, between the two groups of welding mechanisms, and the unloading point in sequence. During the welding process of the copper busbar, the copper busbar can be taken and placed at the same time, thereby realizing continuous welding of the copper busbar and improving the welding efficiency of the copper busbar. Secondly, two groups of welding guns are used to weld both sides of the joint of the copper busbar at the same time, further improving the welding efficiency of the copper busbar.

[0007] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion. When the two groups of copper bars move toward the direction between the two groups of welding mechanisms along the unloading rack, the rollers on the unloading rack first roll along the annular plate, and then the rollers are squeezed by the inclined surface of the end of the pad, so that the rollers drive the support plate together with the first movable plate to move toward the second movable plate. The first movable plate slides along the three groups of guide pillars, and the three groups 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 becomes greater, so that the copper bar is clamped between the movable splint and the fixed plate more firmly, avoiding the occurrence of incomplete welding or burn-through at the splicing.

[0008] Preferably, the unloading rack also includes a lifting plate, which is movably mounted in the base, a receiving block fixedly mounted on the lower end surface of the lifting plate, two groups of top plates symmetrically mounted on the lifting plate, a second spring arranged in the middle of the lifting plate, two groups of through holes symmetrically opened on the lifting plate, the through holes are slidably connected to the slide rod, the slide rod is fixedly mounted in the base, a rectangular hole is opened on the support plate, the upper end of the top plate is movably plugged into the rectangular hole, a horizontal plate is provided between the two groups of transmission shafts, the transmission shaft is rotatably connected to the horizontal plate, and a second cylinder for pushing the receiving block is fixedly mounted on the horizontal plate; Start the second cylinder, and the output end of the second cylinder pushes the receiving block together with the lifting plate to move 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 to move upward. The top plates push the copper bars upward along the rectangular holes, so that the two sets of copper bars are separated from the discharge chute, making it easier for the staff to remove the copper bars.

[0009] The beneficial effects of the present invention are as follows: 1. By driving several groups of unloading racks to make circular motion, the unloading racks can pass through the loading point, the space between the two groups of welding mechanisms, and the unloading point in sequence. During the welding process of the copper bar, the copper bar can be taken and placed at the same time, thereby realizing continuous welding of the copper bar and improving the welding efficiency of the copper bar. Secondly, two groups of welding guns can weld both sides of the joint of the copper bar at the same time, further improving the welding efficiency of the copper bar.

[0010] 2. When the discharge rack is located at the loading point, the spacing of the discharge troughs is slightly smaller than the thickness of the copper busbar. Therefore, when placing the copper busbar into the discharge trough, first pull the second movable plate toward the first movable plate, and the second movable plate slides along the three sets of guide pillars, 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 splints back to the corresponding fixed plates through the four sets of L-shaped rods, so that the spacing of the discharge troughs is enlarged, which is convenient for the staff to place the copper busbar into the discharge trough.

[0011] 3. Loosen the second movable plate. Under the rebound force of the first spring, the movable splint will move toward the fixed plate, so that the copper bar is clamped between the movable splint and the fixed plate, thereby pre-fixing the two groups of copper bars. When the two groups of copper bars move toward the direction between the two groups of welding mechanisms along the unloading rack, the roller on the unloading rack first rolls along the annular plate, and then the roller is squeezed by the inclined surface of the end of the pad, so that the roller drives the support plate together with the first movable plate to move toward the second movable plate. The first movable plate slides along the three groups of guide pillars, and the three groups of first springs are further compressed by the first movable plate until the roller rolls onto the pad. The rebound force of the further compressed first spring becomes greater, so that the copper bar is clamped between the movable splint and the fixed plate more firmly, avoiding the occurrence of incomplete welding or burn-through at the splicing.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] Example 1: Figures 1 to 4 As shown, a busbar copper bar welding device described in an embodiment of the present invention includes a frame 1, two sets of transmission shafts 2 are symmetrically installed in the frame 1, two sets of sprockets 3 are symmetrically installed on the transmission shaft 2, the two sets of sprockets 3 respectively engage with two sets of chains 4, and several sets of unloading racks 5 are arranged between the two sets of chains 4. Two sets of welding mechanisms 6 are symmetrically arranged on the frame 1, and two sets of unloading troughs 51 for placing copper bars 7 are symmetrically arranged on the unloading racks 5. The welding mechanism 6 includes a conveying mechanism 601, which is fixedly installed on the side of the frame 1, a first cylinder 602 fixedly installed on the conveying mechanism 601, and a welding gun 603 fixedly installed on the first cylinder 602.

[0027] Specifically, the transport mechanism 601 adopts the ball screw structure in the prior art. Figure 1 The arrow in the middle indicates the feeding point. Figure 2The position indicated by the middle arrow is the loading point. In the initial state, there is a set of unloading racks 5 at both the loading point and the unloading point. When the copper bars 7 need to be welded, the two sets of copper bars 7 are placed on a set of unloading racks 5 located at the loading point, so that the two sets of copper bars 7 are respectively located in the two sets of unloading troughs 51 of the unloading racks 5. The two sets of unloading troughs 51 are limited to achieve the pre-splicing of the two sets of copper bars 7. Then, a set of transmission shafts 2 are driven by a motor to rotate, and the transmission shafts 2 drive the two sets of sprockets 3 to rotate. The two sets of sprockets 3 drive the two sets of chains 4 to connect. The same group of unloading racks 5 make circular motions, with the direction of the loading point pointing to the unloading point being the direction of the circular motion, so that the two groups of copper bars 7 that have been spliced ​​are moved between the two groups of welding mechanisms 6 along with the corresponding unloading racks 5, and then the two groups of first cylinders 602 are started at the same time, and the first cylinders 602 push the heads of the welding guns 603 close to the splicing of the two groups of copper bars 7, and the welding guns 603 are started to weld the splicing, and at the same time, the first cylinders 602 and the welding guns 603 are driven by the transport mechanism 601 to move along the splicing to achieve the two groups of copper bars 7. During the welding process, the two groups of copper bars 7 can be placed on the unloading rack 5 at the loading point. After the welding is completed, the welding gun 603 is withdrawn, and several groups of unloading racks 5 are driven to make circular motions, so that the next group of two pre-assembled copper bars 7 are moved between the two welding mechanisms 6. At the same time, the two welded copper bars 7 are moved to the unloading point. During the welding process of the copper bars 7, the copper bars 7 at the unloading point can be removed from the corresponding unloading rack 5 at the same time, and the two groups of copper bars 7 to be welded can be placed on the loading point. The above operation is repeated on the unloading rack 5 at the position. Compared with the prior art, by driving several groups of unloading racks 5 to make circular motion, the unloading rack 5 can pass through the loading point, between the two groups of welding mechanisms 6, and the unloading point in sequence. During the welding process of the copper bar 7, the copper bar 7 can be taken and placed at the same time, thereby realizing continuous welding of the copper bar 7 and improving the welding efficiency of the copper bar 7. Secondly, the two groups of welding guns 603 are used to weld the two sides of the splicing of the copper bar 7 at the same time, further improving the welding efficiency of the copper bar 7.

[0028] like Figures 5 to 7As shown, the unloading rack 5 includes a base 501, two groups of chains 4 are connected to both sides of the base 501, three groups of guide pillars 502 are fixedly installed on the base 501, a first movable plate 503 is slidably connected to the three groups of guide pillars 502, a second movable plate 504 is slidably connected to the three groups of guide pillars 502, three groups of first springs 505 are arranged between the first movable plate 503 and the second movable plate 504, the three groups of first springs 505 are respectively sleeved on the three groups of guide pillars 502, two groups of support plates 506 symmetrically installed on the base 501, a fixed plate 509 fixedly installed on the support plate 506, a movable splint 508 movably installed on the support plate 506, two groups of L-shaped rods 507 fixedly connected to the movable splint 508, and two groups of L The lower ends of the profile rods 507 are fixedly connected to the second movable plate 504. The area enclosed by the fixed plate 509 and the movable splint 508 is the discharge trough 51. Two groups of guide grooves 5061 are symmetrically provided on the support plate 506. Two groups of guide rails 5081 are symmetrically provided at the lower end of the movable splint 508. The two groups of guide rails 5081 are respectively slidably connected to the two groups of guide grooves 5061. 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 rollingly 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.

[0029] Specifically, before welding the joint of the two sets of copper bars 7, since the two sets of copper bars 7 are not fixed, thermal stress will cause the two sets of copper bars 7 to deviate during welding, so that the joint of the two sets of copper bars 7 is not welded through or burned through, reducing the welding quality. When the discharge rack 5 is located at the loading point, the spacing of the discharge trough 51 is slightly smaller than the thickness of the copper bar 7. Therefore, when the copper bar 7 is placed in the discharge trough 51, the second movable plate 504 is first pulled toward the first movable plate 503, and the second movable plate 504 moves along the three movable plates. The guide pillars 502 slide, causing the three groups of first springs 505 to be compressed by the second movable plate 504. At the same time, the second movable plate 504 uses the four groups of L-shaped rods 507 to move the two groups of movable clamping plates 508 away from the corresponding fixed plates 509, thereby widening the spacing between the discharge troughs 51 and facilitating the staff to place the copper busbar 7 into the discharge trough 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 toward the fixed plates 509, so that the copper busbar 7 is clamped between the movable clamping plates 50 8 and the fixed plate 509, the two groups of copper bars 7 are pre-fixed. When the two groups of copper bars 7 move with the unloading rack 5 toward the direction between the two groups of welding mechanisms 6, the roller 5032 on the unloading rack 5 first rolls along the annular plate 101, and then the roller 5032 is squeezed by the inclined surface 103 at the end of the pad 102, so that the roller 5032 drives the support plate 5031 together with the first movable plate 503 to move toward the second movable plate 504. The first movable plate 503 slides along the three groups of guide pillars 502, and the three groups of first springs 505 is 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 becomes greater, so that the copper busbar 7 is clamped more firmly between the movable clamping plate 508 and the fixed plate 509, avoiding the occurrence of incomplete welding or burn-through at the splicing point. When welding is completed, the copper busbar 7 moves toward the unloading point along with the unloading rack 5, and the roller 5032 on the unloading rack 5 will stagger the pad 102, which will release the compression of the first movable plate 503 on the first spring 505.

[0030] Example 2: Figures 8 to 11As shown, comparative example 1, wherein another embodiment of the present invention is: the material rack 5 also includes a lifting plate 510, the lifting plate 510 is movably mounted in the base 501, a receiving block 511 is fixedly mounted on the lower end surface of the lifting plate 510, two groups of top plates 512 are symmetrically mounted on the lifting plate 510, a second spring 513 is arranged at the middle part of the lifting plate 510, two groups of through holes 5101 are 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 mounted 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 arranged between the two groups of transmission shafts 2, the transmission shaft 2 is rotatably connected to the horizontal plate 201, and a second cylinder 202 for pushing the receiving block 511 is fixedly mounted on the horizontal plate 201.

[0031] Specifically, when the copper busbar 7 moves to the unloading point along with the discharge rack 5, the receiving block 511 is just above the second cylinder 202, and the second cylinder 202 is started. The output end of the second cylinder 202 pushes the receiving block 511 and moves upward together with the lifting plate 510. The lifting plate 510 slides upward along the two groups of sliding rods 5102 and compresses the second spring 513. At the same time, the lifting plate 510 pushes the two groups of top plates 512 to move upward. The top plates 512 push the copper busbar 7 upward along the rectangular hole 5062, so that the two groups of copper busbars 7 are separated from the discharge trough 51, thereby facilitating the staff to remove the copper busbar 7.

[0032] Working principle: two groups of copper bars 7 are placed on a set of discharge racks 5 located at the loading point, so that the two groups of copper bars 7 are respectively located in the two groups of discharge troughs 51 of the discharge racks 5, and the two groups of copper bars 7 are pre-spliced ​​through the limit of the two groups of discharge troughs 51. Then, a group of transmission shafts 2 are driven by a motor to rotate, and the transmission shafts 2 drive the two groups of sprockets 3 to rotate. The two groups of sprockets 3 drive the two groups of chains 4 together with several groups of discharge 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 groups of copper bars 7 are moved between the two groups of welding mechanisms 6 along with the corresponding discharge racks 5, and then the two groups of first cylinders 602 are started at the same time. The first cylinder 602 pushes the head of the welding gun 603 close to the splicing of the two groups of copper bars 7, and the welding gun 6 is started. 03 weld the joints, and at the same time, drive the first cylinder 602 and the welding gun 603 to move along the joints through the conveying mechanism 601 to realize the welding of the two groups of copper bars 7. During this process, the two groups of copper bars 7 can continue to be placed on the unloading rack 5 located at the loading point. After welding is completed, withdraw the welding gun 603, and continue to drive several groups of unloading racks 5 to make circular motions, so that the next group of two pre-spliced ​​copper bars 7 are moved between the two groups of welding mechanisms 6, and at the same time, the two welded groups of copper bars 7 are moved to the unloading point. During the welding process of the copper bars 7, the copper bars 7 at the unloading point can be removed from the corresponding unloading rack 5 at the same time, and the two groups of copper bars 7 to be welded can be placed on the unloading rack 5 located at the loading point, and the above operation is repeated in a cycle. When the discharge rack 5 is located at the loading point, the spacing of the discharge trough 51 is slightly smaller than the thickness of the copper busbar 7. Therefore, when the copper busbar 7 is placed in the discharge trough 51, the second movable plate 504 is first pulled toward the first movable plate 503, and the second movable plate 504 slides along the three groups of guide pillars 502, so that the three groups of first springs 505 are compressed by the second movable plate 504. At the same time, the second movable plate 504 uses four groups of L-shaped rods 507 to move the two groups of movable splints 508 back to the corresponding fixed plates 509, so that the spacing of the discharge trough 51 is enlarged, which is convenient for the staff to place the copper busbar 7 into the discharge trough 51. Then, the second movable plate 504 is released. Under the rebound force of the first spring 505, the movable splint 508 will move toward the fixed plate 509, so that the copper busbar 7 is clamped between the movable splints The two groups of copper bars 7 are pre-fixed between 508 and the fixed plate 509. When the two groups of copper bars 7 move toward the direction between the two groups of welding mechanisms 6 along with the unloading rack 5, the roller 5032 on the unloading rack 5 first rolls along the annular plate 101, and then the roller 5032 is squeezed by the inclined surface 103 at the end of the pad 102, so that the roller 5032 drives the support plate 5031 together with the first movable plate 503 to move toward the second movable plate 504. The first movable plate 503 slides along the three groups of guide pillars 502, and the three groups 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 becomes greater, so that the copper bar 7 is clamped between the movable clamping plate 508 and the fixed plate 509 more firmly. When the copper busbar 7 moves to the unloading point along with the discharge rack 5, the receiving block 511 is just above the second cylinder 202, and the second cylinder 202 is started. The output end of the second cylinder 202 pushes the receiving block 511 and moves upward together with the lifting plate 510. The lifting plate 510 slides upward along the two groups of sliding rods 5102 and compresses the second spring 513. At the same time, the lifting plate 510 pushes the two groups of top plates 512 to move upward. The top plates 512 push the copper busbar 7 upward along the rectangular hole 5062, so that the two groups of copper busbars 7 are separated from the discharge trough 51.
