Description

Technical Field

[0001] This invention relates to the field of copper busbar welding technology, and more specifically to a copper busbar welding machine. Background Technology

[0002] In the diffusion welding process of soft copper busbars, under high temperature, high pressure, and long duration, the atoms on the surfaces of the joined soft copper busbars diffuse into each other, forming a strong metallurgical bond. This welding method can achieve high-quality connections, and the joints have good electrical conductivity, thermal conductivity, and mechanical properties. Compared with traditional welding methods, diffusion welding of soft copper busbars results in joints with high strength, low residual stress, and no obvious welding defects such as porosity or slag inclusions. Furthermore, because it is performed in the solid state, it avoids problems such as component segregation that may occur during melting and solidification.

[0003] The current processing method for welding soft copper busbars is as follows: First, multiple copper sheets are manually stacked together. Then, the worker inserts one end of the copper stack into the diffusion welding head and welds one end first. After welding, the stack is removed with a wet towel and the other end is welded. After both ends of the copper stack are welded, the processed soft copper busbar can be placed in water.

[0004] A patent for an automatic welding equipment for processing soft copper busbars, with announcement number CN118616871A, includes a main body comprising a lower chassis, a back plate, and a top plate. The back plate is vertically mounted on the back surface of the lower base, and a top plate is vertically mounted on the top of the back plate. A diffusion welding assembly is horizontally mirror-symmetrically mounted on the bottom surface of the top plate. A transfer assembly is slidably mounted on the surface of the main support assembly. Anti-adhesive application assemblies are symmetrically arranged at both ends of the lower chassis, positioned opposite each other on the outside of the diffusion welding assembly. Cooling assemblies are symmetrically arranged on the inner wall of the back plate, symmetrically positioned on both sides of the main support assembly, and positioned opposite each other on the inside of the diffusion welding assembly. The transfer assembly enables automatic loading and unloading of copper stacks without manual handling, preventing worker burns. The cooling assembly is designed to deliver water to the center of the copper stacks in real time during welding, providing excellent cooling and ensuring effective diffusion welding.

[0005] However, in the copper busbar welding process, the patent uses a design where a sponge block contacts the copper stack to fully cool it. But after the upper and lower diffusion welding heads complete the copper busbar welding, there will be welding debris adhering to the surface of the diffusion welding heads. This debris may affect the subsequent welding and reduce the welding quality of the copper busbar.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

[0007] The purpose of this invention is to provide a copper busbar welding machine that can effectively solve the above-mentioned technical problems.

After the copper busbar is welded, under the action of the transmission component, the water stored in the water tank is sprayed onto the surface of the upper and lower diffusion welding heads to wash away the welding debris, preventing welding debris from remaining on the diffusion welding heads and affecting the next use. At the same time, the anti-sticking agent is replenished inside the liquid storage tank for easy use next time. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0033] like Figures 1 to 8 As shown, the present invention provides a copper busbar welding machine, comprising: a main body 1, an upper diffusion welding head 2, a lower diffusion welding head 4 fixedly installed on the main body 1, a hydraulic cylinder 3 for driving the upper diffusion welding head 2 to move downward for copper stack welding, a support guide rail 5 fixedly installed on the top wall of the main body 1 and slidably installed on the main body 1, an electric push rod 501 for driving the support guide rail 5 to move, one end of the electric push rod 501 fixedly installed on the main body 1, and the output end of the electric push rod 501 fixedly installed on one side of the bottom of the support guide rail 5. The extension and retraction of the output end of the electric push rod 501 drives the copper stack placed on the support guide rail 5 to move, avoiding the safety hazards that exist when manually grasping the welding parts for welding. A positioning component 6 is set on the support guide rail 5 to automatically clamp the copper stack, and a rinsing component 7 is set on the main body 1 to rinse the surface of the diffusion welding head after welding.

[0034] The positioning component 6 includes: a positioning element 601 for clamping and fixing the copper laminations on the support guide rail 5; a lifting frame 602 for moving the positioning element 601; the inner wall of the lifting frame 602 has symmetrical slots with sliding grooves; a slider that cooperates with the sliding grooves on the inner wall of the lifting frame 602 is fixedly connected to the surface of the support guide rail 5; the lifting frame 602 is slidably mounted on the slider on the surface of the support guide rail 5 through the sliding grooves; and a guide element 603 for guiding the movement of the lifting frame 602; the main body 1 has an installation groove, and the guide element 603 is fixedly mounted on the inner wall of the installation groove.

[0035] The guide member 603 consists of a guide groove 6031 formed in the middle of the guide member 603 and a guide pin 6032 rotatably mounted on the bottom of the lifting frame 602;

[0036] In the existing design, manual clamping of workpieces for welding poses a risk of burns and safety hazards. To address this, when the support guide rail 5 moves the copper stacked sheets to the positions of the upward and downward diffusion welding heads 2 and 4, a guide pin 6032 rotating at the bottom of the lifting frame 602 moves within the guide groove 6031. When the guide pin 6032 moves to the position of the downward diffusion welding head 4, it causes the lifting frame 602, which is slidably mounted on the support guide rail 5, to move downward. This causes the positioning element 601 at the top of the lifting frame 602 to press against the copper stacked sheets, automatically clamping and fixing the copper stacked sheets. This avoids the safety hazards associated with manual welding. After the support guide rail 5 resets, the guide pin 6032 moves to the upper part of the guide groove 6031, causing the lifting frame 602 to move upward, automatically releasing the positioning element 601 from clamping the copper busbar.

[0037] Since the size of the guide groove 6031 is fixed, after the copper laminations placed on the surface are moved into place by the support guide rail 5, the positioning component 601 can only clamp and position copper laminations of a single thickness, which is not very practical. The positioning component 601 is composed of an adjusting bolt 6011 threaded on the lifting frame 602 and a clamping plate 6012 fixedly installed at the bottom of the adjusting bolt 6011. By rotating the adjusting bolt 6011 on the top of the lifting frame 602, the distance between the clamping plate 6012 and the surface of the support guide rail 5 can be adjusted, thereby facilitating the clamping of copper laminations of various thicknesses and improving practicality.

[0038] The flushing assembly 7 includes: a water tank 701 fixedly installed on the main body 1; a water reservoir 702 fixedly installed on the water tank 701; a first piston rod 703 that pushes water inside the water reservoir 702 to flush welding waste; a flushing nozzle 704 fixedly installed on the water reservoir 702; a water outlet fixedly connected to the flushing nozzle 704; a first sealing rod 706 that seals the first fixing rings 705 fixedly installed at both ends inside the water reservoir 702; the inner ring of the first fixing ring 705 is provided with a conical hole, and one end of the first sealing rod 706 is provided with a cone shape that matches the conical hole on the first fixing ring 705 to improve the sealing effect between the two; and a first spring 707 that drives the first sealing rod 706 to reset. The first spring 707 is fitted onto the first sealing rod. On the surface of 706, one end of the first spring 707 is fixedly connected to the surface of the first fixed ring 705, and the other end of the first spring 707 is fixedly installed on the surface of the first sealing rod 706. When the first piston rod 703 squeezes the water inside the water storage cylinder 702, the first sealing rod 706 near the flushing nozzle 704 and the first fixed ring 705 are in an open state. Water passes through the gap between the first sealing rod 706 and the first fixed ring 705 and is sprayed from the flushing nozzle 704 to flush the waste generated by welding on the surfaces of the upper diffusion welding head 2 and the lower diffusion welding head 4. The first sealing rod 706 near the water storage tank 701 and the first fixed ring 705 are pressed and adhered to the inner ring of the first fixed ring 705 by the elastic reset of the first spring 707 to seal. The transmission assembly 8 is provided between the first piston rod 703 and the support guide rail 5.

[0039] The transmission assembly 8 includes: a positioning bracket 801 fixedly mounted on the main body 1; a gear shaft 802 rotatably mounted on the positioning bracket 801; a first rack 803 and a second rack 804 respectively meshing with the gear shaft 802, with one end of the second rack 804 fixedly mounted on the first piston rod 703; a connecting block 805 that drives the first rack 803 to move; one end of the connecting block 805 is fixedly connected to the surface of the support guide rail 5; the other end of the connecting block 805 is fixedly connected to one end of the first rack 803; during the movement of the support guide rail 5, the support guide rail 5 pushes the first rack 803 to mesh with the gear shaft 802 rotatably mounted on the positioning bracket 801 through the surface-fixed connecting block 805, thereby causing the gear shaft 802 to mesh with the second rack 804; and a coating assembly 9 provided on the other end of the second rack 804 for applying an anti-sticking agent to the copper lamination welding joint.

[0040] To prevent the solder from sticking together on the surface of the copper busbar at high temperatures, thus affecting the welding quality;

[0041] As the copper laminations placed on the support guide rail 5 move upward and downward diffusion welding heads 2 and 4, the connecting block 805 fixed to the surface of the support guide rail 5 drives the first rack 803 to mesh and rotate with the gear shaft 802, causing the gear shaft 802 to drive the second rack 804 to mesh and move. At this time, one end of the second rack 804 drives the first piston rod 703 to move toward the position of the gear shaft 802, so that the first fixing ring 705 and the first sealing rod 706 near the end of the water tank 701 are in an open state, and the water in the water tank 701 flows through the gap to... The water is stored in the storage cylinder 702. At the same time, as the copper stack moves on the support guide rail 5, the other end of the second rack 804 squeezes the anti-sticking agent stored inside the storage cylinder 902 through linkage, so that the second sealing rod 906 and the second fixing ring 905 near the coating nozzle 904 are in an open state. The anti-sticking agent is sprayed from the coating nozzle 904 through the gap between the second sealing rod 906 and the second fixing ring 905 to coat the upper and lower surfaces of the moving copper stack. This can ensure that after welding, the diffusion welding head and the copper busbar are completely separated and will not stick together.

[0042] In addition, after the copper busbar is welded, there are often waste chips generated during the welding process left on the diffusion welding head. These waste chips may affect subsequent welding processes.

[0043] After welding is completed, when the support guide rail 5 is reset, the second rack 804 moves in the opposite direction. The second fixing ring 905 and the second sealing rod 906, located near the liquid storage tank 901 inside the liquid storage cylinder 902, are in an open state, and anti-sticking agent is added to the inside of the liquid storage cylinder 902. Meanwhile, the first fixing ring 705 and the first sealing rod 706, located near the flushing nozzle 704 inside the water storage cylinder 702, are in an open state, and the flushing nozzle 704 sprays out the waste generated during welding on the surfaces of the upper diffusion welding head 2 and the lower diffusion welding head 4 to wash away the welding waste, preventing welding waste from remaining on the diffusion welding head and affecting the next use.

[0044] The coating assembly 9 includes: a liquid storage tank 901 fixedly installed on the main body 1; a liquid storage cylinder 902 fixedly installed on the liquid storage tank 901; a second piston rod 903 that pushes the anti-sticking agent inside the liquid storage cylinder 902 to coat the copper laminations, with one end of the second piston rod 903 fixedly connected to the other end of the second rack 804; a coating nozzle 904 fixedly installed on the liquid storage cylinder 902; a second sealing rod 906 that seals the second fixing ring 905 and the second fixing ring 905, with the inner ring of the second fixing ring 905 having a conical hole, and one end of the second sealing rod 906 having a cone shape that matches the conical hole on the second fixing ring 905 to improve the sealing effect between the two; and a second spring 907 that drives the second sealing rod 906 to reset.

[0045] The second spring 907 is fitted onto the surface of the second sealing rod 906. One end of the second spring 907 is fixedly connected to the surface of the second fixing ring 905, and the other end of the second spring 907 is fixedly installed on the surface of the second sealing rod 906. When the second piston rod 903 squeezes the anti-sticking agent inside the liquid storage cylinder 902, the second sealing rod 906 near the coating nozzle 904 is in an open state with the second fixing ring 905. The anti-sticking agent is sprayed from the coating nozzle 904 through the gap between the second sealing rod 906 and the second fixing ring 905 to coat the upper and lower surfaces of the copper stack with anti-sticking agent. This ensures that after welding, the diffusion welding head and the copper busbar are completely separated and will not stick together. The second sealing rod 906 near the liquid storage tank 901 is pressed against the inner ring of the second fixing ring 905 by the elastic reset of the second spring 907 to seal it.

[0046] A through groove 102 is provided on the surface of the main body 1, and a collection box 10 is placed at the bottom of the main body 1, with the collection box 10 located below the through groove 102. The arrangement of the through groove 102 and the collection box 10 facilitates the collection of sprayed water and anti-sticking agent.

[0047] A barrier 101 is fixedly installed on the surface of the main body 1. The barrier 101 blocks the sprayed water and anti-sticking agent, allowing them to flow through the channel 102 into the collection box 10 for collection.

[0048] Working principle: When the power is turned on and the copper busbar welding machine is in use, the copper stack is placed on the surface of the support guide rail 5. When the electric push rod 501 moves the support guide rail 5 to the positions of the upward diffusion welding head 2 and the downward diffusion welding head 4, the guide pin 6032 rotating at the bottom of the lifting frame 602 moves in the guide groove 6031 on the guide member 603. When the guide pin 6032 moves to the position of the downward diffusion welding head 4, the guide pin 6032 drives the lifting frame 602, which is slidably installed on the support guide rail 5, to move down, so that the positioning member 601 at the top of the lifting frame 602 presses on the copper stack, realizing automatic clamping and fixing of the copper stack. At the same time, the connecting block 805 fixed on the surface of the support guide rail 5 drives the first rack 803 to mesh and rotate with the gear shaft 802, so that the gear shaft 802 drives the second rack 804 to mesh and move. At this time, one end of the second rack 804 drives the first piston rod. 703 moves to the position of gear shaft 802, so that the first fixing ring 705 and the first sealing rod 706 near the end of the water tank 701 are in an open state. The water in the water tank 701 flows through the gap to the water storage cylinder 702 for storage. Through linkage, the other end of the second rack 804 squeezes the anti-sticking agent stored inside the liquid storage cylinder 902, so that the second sealing rod 906 near the end of the coating nozzle 904 is in an open state with the second fixing ring 905. The anti-sticking agent is sprayed from the coating nozzle 904 through the gap between the second sealing rod 906 and the second fixing ring 905 to coat the upper and lower surfaces of the moving copper stack with anti-sticking agent. This can ensure that after welding, the diffusion welding head and the copper busbar are completely separated and will not stick. Then, the output end of the hydraulic cylinder 3 pushes the upper diffusion welding head 2 down to weld the copper stack between the upper diffusion welding head 2 and the lower diffusion welding head 4.

[0049] When the support guide rail 5 is reset after welding, the second rack 804 moves in the opposite direction. The second fixing ring 905 and the second sealing rod 906 inside the liquid storage cylinder 902, which are located near the liquid storage tank 901, are in an open state. Anti-sticking agent is added to the inside of the liquid storage cylinder 902. Meanwhile, the first fixing ring 705 and the first sealing rod 706 inside the water storage cylinder 702, which are located near the flushing nozzle 704, are in an open state. The water is then sprayed from the flushing nozzle 704 to flush the welding debris generated on the surfaces of the upper diffusion welding head 2 and the lower diffusion welding head 4, so as to prevent welding debris from remaining on the diffusion welding head and affecting the next use.
