[0002] Busbar is the name of the conductive material on the power distribution equipment. It is made of flat copper and has no insulation layer. The outside is painted with the color indicating the phase sequence or covered with a sleeve of the corresponding color. It is mainly used to connect the indoor transformer to the distribution cabinet, then to the main power switch and then to each branch switch. When the busbar is installed, it needs to be welded to the specified length as required, and a welding mechanism will be used in this process.

[0003] Related technology (publication number: CN217596126U) discloses a busbar copper busbar welding mechanism, which discloses a technical solution: first, the copper busbar can be clamped and fixed by a clamping structure, and the clamping structure is connected by a clamping seat, a rubber pad, and a spring combination, so as to protect the copper busbar. Secondly, the welding fume is sucked away by the provided suction device. At the same time, the filter box can purify the inhaled fume, thereby achieving a better environmental protection effect.

[0004] In the above-mentioned disclosed technical solutions, the following problems were found in the related technologies: when welding the busbar, it is necessary to perform welding processing around the welding point, so the busbar needs to be flipped over. Directly flipping and adjusting the welding surface during the welding process increases the danger of the operation process. Flipping and reprocessing after pausing will increase the welding process, thereby affecting the efficiency of the welding process, and the welding point will also cause unevenness. In response to this, we have proposed a new busbar copper busbar welding mechanism.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the busbar copper bar welding mechanism:

[0018] 1. The driving component drives the bracket to rotate, so that the bracket drives the copper bar to rotate at a uniform speed in the circumferential direction. During this process, the welding point is welded by the welding gun, so that the welding points of the two copper bars are welded evenly, thereby ensuring the welding quality of the busbar copper bar.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] The following is a combination of specific implementation cases and attached Figure 1-5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0033] A busbar copper busbar welding mechanism includes a welding frame 1, wherein both side walls of the welding frame 1 are rotatably provided with a bracket 2, and a driving member for driving the bracket 2 to rotate is provided on the side walls of the welding frame 1. Movable holes penetrating the inner cavity are provided on both longitudinal side frames of the welding frame 1, and the aperture of the movable hole corresponds to the circular bracket 2, so that the bracket 2 is movably embedded in the inside of the movable hole and rotates circumferentially. The bracket 2 is driven to rotate by the driving member, so that the bracket 2 drives the copper busbar to rotate at a uniform speed in the circumference. The driving member and the bracket 2 are located on the same side of the welding frame 1. During this process, the welding joints are welded by the welding gun 4, so that the welding joints of the two copper busbars are welded evenly, thereby ensuring the welding quality of the busbar copper busbar. The welding surface of the busbar copper busbar can also be adjusted by the driving member, so that the operation of the welding process is more convenient, thereby improving the safety of the welding frame process.

[0034] A balancing seat 3 for supporting the center of gravity of the copper busbar is symmetrically arranged between the two brackets 2, and a center of gravity adjustment component for adjusting the position of the balancing seat 3 is arranged on the circumferential outer wall of the bracket 2. The balancing seat 3 and the bracket 2 are the same cylindrical components, and a through cavity that penetrates the inner cavity is opened on the surface of the balancing seat 2 and the bracket 2. The through cavity is a flat cavity, so that the busbar copper busbar can pass through the balancing seat 3 and the bracket 2. A locking piece 10 that is clamped to the surface of the copper busbar is provided on the top of the balancing seat 3. The position of the two balancing seats 3 is adjusted simultaneously by the center of gravity adjustment component, so that the two balancing seats 3 are respectively moved to the center of gravity position of the two copper buses to be welded, thereby ensuring the stability of the copper busbar welding process, and then ensuring the quality of the copper busbar welding.

[0035] A welding gun 4 is mounted on the top inner wall of the welding frame 1. It is positioned centrally between the two brackets 2. After the copper busbars to be welded are butted together, the longitudinal position of the welding gun 4 is adjusted using a horizontal and vertical adjustment mechanism, allowing the copper busbars to be welded using the welding gun 4. Adjusting the horizontal position of the welding gun 4 using the horizontal and vertical adjustment mechanism ensures a uniform welding speed across the welded joint, thereby ensuring the quality of the busbar welding.

[0036] Below the welding gun 4 is a liquid storage tank 5 fixed to the inner cavity of the welding frame 1. Two parallel and co-horizontal base frames 26 are fixedly mounted between the inner walls of the welding frame 1. The liquid storage tank 5 is snugly attached to the two base frames 26. The liquid storage tank 5 stores coolant and can also store cooling water. A return water funnel 14 is provided on the top of the liquid storage tank 5. Brackets 16 are fixedly mounted on the top of the liquid storage tank 5, and the return water funnel 14 is secured between the brackets 16. The recovery funnel 14 is fixed near the weld.

[0037] A pressure pump 27 is embedded in the inner cavity of the return funnel 14. The pressure pump 27 is fixed to the inside of the return funnel 14 via a base and is electrically connected to an external power source via a wire. A nozzle 23 is provided at the water outlet of the pressure pump 27, and the water inlet of the pressure pump 27 passes through the inner cavity of the return funnel 14 and extends to the inner cavity of the liquid storage tank 5. The water inlet of the pressure pump 27 is fixedly connected to one end of the liquid inlet pipe 15, and the other end of the liquid inlet pipe 15 passes through the leakage hole in the center of the return funnel 14 and extends to the interior of the liquid storage tank 5. The diameter of the central leakage hole of the return funnel 14 is larger than the diameter of the liquid inlet pipe 15, so that a return water gap is left between the liquid inlet pipe 15 and the leakage hole of the return funnel 14.

[0038] During the busbar copper busbar welding process, the pressure pump 27 is connected to a power source. This allows the pressure pump 17 to draw coolant from the reservoir 5 through the liquid inlet pipe 15 and onto the nozzle 23. The nozzle 23 sprays the coolant onto the surface of the copper busbar being welded. Because the copper busbar is thermally conductive, this coolant cools the busbar during welding, ensuring welding quality while improving safety during the welding process.

[0039] It is worth noting that a protective cap 28 is provided between the pressure pump 27 and the nozzle 23, and is embedded in the inner cavity of the return funnel 14. The protective cap 28 is conical in shape and is fixedly mounted on the outside of the connecting pipe between the pressure pump 27 and the nozzle 23 through a central mounting hole. The conical protective cap 28 allows the coolant sprayed on the surface of the copper busbar by the nozzle to fall back into the return funnel 14 and onto the protective cap 28. The inclined surface of the protective cap 28 allows the coolant to bypass the pressure pump 27 and fall back into the liquid storage tank 5, allowing the coolant to be recycled through the pressure pump 27.

[0040] In addition, a metering window 29 is embedded in the side wall of the liquid storage tank 5. The metering window 29 is made of transparent material and has scale lines on it, through which the remaining amount of coolant in the liquid storage tank 5 can be understood.

[0041] In addition, the welding gun 4 is arranged on the top of the inner wall of the welding frame 1 through a horizontal and vertical adjustment mechanism. Through the horizontal and vertical adjustment mechanism, the welding gun 4 is moved longitudinally to the welding position, and the horizontal position of the welding gun 4 can also be adjusted to perform positioning welding on the copper bar.

[0042] Furthermore, the horizontal and vertical adjustment mechanism includes a guide rail 7 arranged horizontally at the top of the inner wall of the welding frame 1, and an electric telescopic member 8 is longitudinally arranged on the slider of the guide rail 7. The movable end of the electric telescopic member 8 is provided with the welding gun 4. The guide rail 7 is an electric guide rail, which is fixed to the top of the inner wall of the welding frame 1. The electric telescopic member 8 is vertically fixed to the bottom of the slider of the guide rail 7. The movable end of the electric telescopic member 8 is fixedly connected to the welding gun 4, which is connected to the welding box for use. The electric telescopic member 8 and the guide rail 7 are both electrically connected to an external power source for use.

[0043] The guide rail 7 allows the welding gun 4 to move along the edge of the welding point to weld the copper busbar, and the electric telescopic member 8 drives the welding gun 4 to move the welding point longitudinally, thereby ensuring the accuracy of the welding point adjustment.

[0044] The drive assembly includes teeth 18 uniformly arranged circumferentially on the outer wall of the bracket 2. A gear 17 is rotatably mounted on the side wall of the welding frame 1, and the gear 17 meshes with the teeth 18. A circle of teeth 18 is continuously arranged on the circumferential outer wall of one of the brackets 2. A motor cover 13 is fixed to the side wall of the welding frame 1 corresponding to the bracket 2. A motor 24 is fixedly embedded and mounted within the inner cavity of the motor cover 13. The motor 24 is electrically connected to an external power source via a wire. The output shaft of the motor 24 passes through the side wall of the motor cover 13 and extends to the outside. The gear 17 is fixedly mounted on the outer wall of the output shaft of the motor 24 extending to the outside through a mounting hole provided in the center.

[0045] When turning over the welding side of the copper bar, the motor 24 is connected to the power supply, so that the output shaft of the motor 24 drives the gear 17 to rotate, and the teeth 18 meshing with the gear 17 drive the bracket 2 to rotate, and the copper bar is turned over by the bracket 2. When welding the side of the copper bar, the copper bar can also be driven to rotate by the bracket 2 rotating at a constant speed, and the welding gun 4 is aimed at the welding point, thereby ensuring the quality of the welding on the side of the copper bar.

[0046] Ball bearings 20 are evenly arranged circumferentially between the inner wall of the movable cavity of the bracket 2 and the welding frame 1. A circumferential chute 25 is provided on the circumferential inner wall of the movable cavity of the bracket 2 and the welding frame 1. A circumferential movable groove 21 is continuously provided on the circumferential outer wall of the bracket 2 at positions corresponding to the chute 25. Ball bearings 20 are movably embedded in the multiple movable cavities formed by each movable groove 21 and the chute 25.

[0047] In the process of the bracket 2 driving the copper busbar to flip, the bracket 2 drives the ball 20 to rotate through the movable groove 21, so that the ball 20 slides on the inner wall of the slide groove 25 at the same time. The circumferential ball 20 ensures the stability of the rotation process of the bracket 2, thereby ensuring the stability of the copper busbar flipping adjustment process.

[0048] The center of gravity adjustment assembly includes a screw 6 rotatably arranged on the circumferential outer wall of the bracket 2, and the outer wall of the screw 6 is symmetrically provided with external threads with opposite threads and the same pitch. The outer wall of the screw 6 is symmetrically threaded with an adjustment seat 9, and the adjustment seat 9 is fixedly mounted on the circumferential outer wall of the balance seat 3. An operating rod is fixedly connected to one end of the screw 6, and the operating rod passes through the inner cavity of the corresponding fixed seat 19 and extends to the outside. The fixed seats 19 are fixedly mounted on the circumferential outer walls of the two brackets 2, and bearings are embedded in the opposite surfaces of the two fixed seats 19. The two ends of the screw 6 are respectively embedded in the inside of the two bearings. The two adjustment seats 9 are respectively provided with threaded through holes in the inner cavity corresponding to the external threads symmetrically of the two parts.

[0049] When welding the busbar copper bar, the two busbar copper bars are respectively passed through the bracket 2 and then through the balance seat 3. After the two busbar copper bars are welded together, the screw 6 is driven to rotate by the operating rod, so that the two adjustment seats 9 connected to the external thread of the screw 6 move relative to or back to back according to the length of the busbar copper bar, so as to adjust the center of gravity position according to the length of the busbar copper bar for support, thereby ensuring the stability of the busbar copper bar welding process.

[0050] Adjustable according to the length of the busbar copper bar, it can be used to process copper bars of different lengths. The locking piece 10 can be a bolt. After adjusting to the center of gravity, screw the locking piece 10 on the top of the balance seat 3 so that the locking piece 10 passes through the inner cavity of the balance seat 3 and engages the surface of the copper bar, thereby fixing the copper bar. The copper bar can then be welded.

[0051] The circumferential outer wall of the bracket 2 is provided with a guide rod 12 parallel to the lead screw 6. The outer wall of the guide rod 12 is sleeved with an anti-deflection seat 11, which is fixedly mounted on the circumferential outer wall of the balance seat 3. A base 22 is fixedly mounted on the circumferential outer wall of each bracket 2. The ends of the guide rod 12 are respectively fixed perpendicularly to the opposing surfaces of the two bases 22. The anti-deflection seat 11 is movably sleeved on the outside of the guide rod 12 via a through hole provided in the center and extending through the inner cavity.

[0052] When adjusting the positions of the two balancing seats 3 according to the center of gravity of the copper busbar being welded, the balancing seats 3 drive the anti-deflection seats 11 to slide against the outer wall of the guide rod 12. The guide rod 12, which is parallel to the screw 6, ensures the stability of the moving direction of the balancing seats 3 and prevents position deviation, thereby ensuring the accuracy of the copper busbar's center of gravity support point and further ensuring the quality of the busbar welding.

[0053] A busbar copper bar welding mechanism operates as follows: First, two busbar copper bars are passed through a bracket 2 and then through a balance seat 3. After the two busbar copper bars are butted together at the weld, an operating lever is used to rotate a lead screw 6, causing two adjustment seats 9, which are externally threaded with the lead screw 6, to move toward or away from each other according to the length of the busbar copper bar, thereby adjusting the center of gravity of the busbar to support the length. The locking member 10 on the top of the balance seat 3 is then screwed, causing it to penetrate the inner cavity of the balance seat 3 and engage the surface of the copper bar, thereby securing the copper bar.

[0054] Then the welding torch 4 is moved to the welding position by the motorized telescopic member 8, and then the welding torch 4 is moved along the joint of the two copper bars at a constant speed by the guide rail 7 to weld the one side surface.

[0055] After the welding process, the welding torch 4 is removed from the welding position, and then the locking member 10 is removed, and then the welded copper bars are removed from the welding frame 1.
