Description

Technical Field

[0001] The invention relates to the technical field of copper bar welding, and in particular to a copper bar welding machine. Background Art

[0002] During the diffusion welding of soft copper bars, under the action of high temperature, high pressure and long time, the atoms on the surface of the connected soft copper bars diffuse with each other to form 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, the joints of soft copper bars diffusion welding have high strength, low residual stress, and will not produce obvious welding defects such as pores and slag inclusions. At the same time, because it is carried out in the solid state, it avoids problems such as component segregation that may occur during melting and solidification.

[0003] When welding and making soft copper busbars, the current processing method is mainly as follows: first, multiple copper sheets are manually stacked together, and then the worker inserts one end of the copper stack into the diffusion welding head, welds one end first, and after welding is completed, uses a wet towel to take it out, and then welds the other end. After both ends of the copper stack are welded, the processed soft copper busbar can be placed in water.

[0004] The announcement number is CN118616871A, a patent for automatic welding equipment for processing soft copper busbars, including a main body, the main body includes a lower chassis, a back plate and a top plate, the back surface of the lower base is vertically provided with a back plate, the top of the back plate is vertically provided with a top plate, and the bottom surface of the top plate is laterally mirror-symmetrically installed with a diffusion welding component; a transfer component is slidably installed on the surface of the main support component, anti-adhesive coating components are symmetrically provided at both longitudinal ends of the lower chassis, the anti-adhesive coating components are relatively arranged on the outside of the diffusion welding component, and cooling components are symmetrically provided on the inner wall of the back plate, and the cooling components are symmetrically arranged on both sides of the main support component, and the cooling components are relatively arranged on the inside of the diffusion welding component; the transfer component can realize automatic loading and unloading of copper stacks without manual handling, thereby avoiding burns to workers; the design of the cooling component can deliver water to the middle of the copper stack in real time during welding, with good cooling effect to ensure the diffusion welding effect.

[0005] However, in the welding of the copper busbar, this patent designs the sponge block to contact the copper stack so as to fully cool the copper stack. However, after the upper and lower diffusion welding heads complete the welding of the copper busbar, waste chips generated after welding will adhere to the surface of the diffusion welding heads. The waste chips may affect the subsequent welding and reduce the welding quality of the copper busbar in the later stage.

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

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

[0033] like Figures 1 to 8 As shown, a copper busbar welding machine of the present invention comprises: a main body 1, an upper diffusion welding head 2, a lower diffusion welding head 4 fixedly mounted on the main body 1, a hydraulic cylinder 3 for driving the upper diffusion welding head 2 to move downward to weld copper laminations, the hydraulic cylinder 3 is fixedly mounted on the top wall of the main body 1, a support guide rail 5 slidably mounted 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 is fixedly mounted on the main body 1, the output end of the electric push rod 501 is fixedly mounted on one side of the bottom of the support guide rail 5, the copper laminations placed on the support guide rail 5 are driven to move by the extension and retraction of the output end of the electric push rod 501, and the safety hazard existing in the welding of the welded parts by manually grabbing them is avoided, a positioning component 6 is arranged on the support guide rail 5 for automatically clamping the copper laminations, and a flushing component 7 is arranged on the main body 1 for flushing the surface of the diffusion welding head after welding;

[0034] The positioning assembly 6 includes: a positioning member 601 for clamping and fixing the copper lamination on the support rail 5, a lifting frame 602 for driving the positioning member 601 to move, and the inner wall of the lifting frame 602 is symmetrically grooved with slide grooves, the surface of the support rail 5 is fixedly connected with a slider that matches the slide groove on the inner wall of the lifting frame 602, the lifting frame 602 is slidably installed on the slider on the surface of the support rail 5 through the slide groove, and a guide member 603 for guiding the movement of the lifting frame 602; a mounting groove is opened on the main body 1, and the guide member 603 is fixedly installed on the inner wall of the mounting groove;

[0035] The guide member 603 is composed of a guide groove 6031 provided 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, there is a situation where the workpiece is manually clamped for welding, which is easy to get burned and has certain safety hazards. When the support rail 5 drives the copper stack placed on the surface to move to the position of the upward diffusion welding head 2 and the lower diffusion welding head 4, the guide pin 6032 rotated by the bottom of the lifting frame 602 moves in the guide groove 6031. 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 slidably installed on the support rail 5 to move downward, so that the positioning piece 601 at the top of the lifting frame 602 is pressed on the copper stack, so as to realize automatic clamping and fixing of the copper stack, and avoid the safety hazards when welding by manually holding the welding piece; after the support rail 5 is reset, the guide pin 6032 moves to the upper part of the guide groove 6031, drives the lifting frame 602 to move upward, so that the positioning piece 601 automatically releases the clamping of the copper bar;

[0037] Since the size of the guide groove 6031 is fixed, after the support rail 5 drives the copper laminate placed on the surface to move into place, the positioning member 601 can only clamp and position the copper laminate of a single thickness, which is not very practical. The positioning member 601 is composed of an adjusting bolt 6011 threadedly installed on the lifting frame 602 and a clamping plate 6012 fixedly installed at the bottom of the adjusting bolt 6011. The adjusting bolt 6011 can be rotated on the top of the lifting frame 602 to adjust the distance between the clamping plate 6012 and the surface of the support rail 5, thereby facilitating the clamping of a variety of copper laminates of insufficient thickness, thereby improving practicality.

[0038] The flushing assembly 7 includes: a water tank 701 fixedly mounted on the main body 1, a water storage cylinder 702 fixedly mounted on the water storage tank 701, a liquid inlet end of the water storage cylinder 702 fixedly connected to the inside of the water storage tank 701, a first piston rod 703 that pushes the water inside the water storage cylinder 702 to flush welding waste, a flushing nozzle 704 fixedly mounted on the water storage cylinder 702, a liquid outlet end of the water storage cylinder 702 fixedly connected to the flushing nozzle 704, and a first fixed ring 705 fixedly mounted at both ends of the inside of the water storage cylinder 702, a first blocking rod 706 for blocking the first fixed ring 705, an inner ring of the first fixed ring 705 is set as a tapered hole, and one end of the first blocking rod 706 is set as a cone that matches the tapered hole on the first fixed ring 705 to improve the blocking effect between the two, a first spring 707 that drives the first blocking rod 706 to reset, and the first spring 707 is sleeved on the first blocking rod The surface of the first spring 707 is fixedly connected to the surface of the first fixing ring 705, and the other end of the first spring 707 is fixedly installed on the surface of the first blocking rod 706. When the first piston rod 703 squeezes the water inside the water storage cylinder 702, the first blocking rod 706 near one end of the flushing nozzle 704 and the first fixing ring 705 are in an open state, and water passes through the gap between the first blocking rod 706 and the first fixing ring 705, and is sprayed from the flushing nozzle 704 to flush the waste chips generated by the welding on the surfaces of the upper diffusion welding head 2 and the lower diffusion welding head 4. The first blocking rod 706 near one end of the water storage tank 701 and the first fixing ring 705 are elastically reset by the first spring 707, so that the first blocking rod 706 is squeezed and fitted on the inner ring of the first fixing ring 705 for sealing, and the transmission component 8 is arranged 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 meshed with the gear shaft 802, and one end of the second rack 804 is 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, and the other end of the connecting block 805 is fixedly connected to one end of the first rack 803. When the support guide rail 5 moves, the support guide rail 5 pushes the first rack 803 to mesh and rotate with the gear shaft 802 rotatably mounted on the positioning bracket 801 through the connecting block 805 fixed on the surface, so that the gear shaft 802 meshes with the second rack 804, and a coating assembly 9 is arranged on the other end of the second rack 804 for coating the anti-sticking agent on the welding position of the copper lamination.

[0040] In order to prevent the solder from bonding on the copper busbar surface at high temperature, thus affecting the welding quality;

[0041] When the copper stack placed on the support rail 5 moves to the position of the upward diffusion welding head 2 and the lower diffusion welding head 4, the connecting block 805 fixed on the surface of the support rail 5 drives the first rack 803 to mesh with the gear shaft 802 and rotate, 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 to move toward the position of the gear shaft 802, so that the first fixing ring 705 and the first blocking rod 706 near one end of the water storage tank 701 are in an open state, and the water in the water storage tank 701 flows to The water is stored in the water storage cylinder 702. At the same time, when the copper stack on the support rail 5 moves, the other end of the second rack 804 squeezes the anti-sticking agent stored in the liquid storage cylinder 902 through linkage, so that the second blocking rod 906 and the second fixing ring 905 near one end of the coating nozzle 904 are in an open state. The anti-sticking agent passes through the gap between the second blocking rod 906 and the second fixing ring 905, and is sprayed from the coating nozzle 904 to coat the upper and lower surfaces of the moving copper stack, which can ensure that after welding, the diffusion welding head is completely separated from the copper busbar without adhesion.

[0042] In addition, after the copper busbar is welded, there is often waste left on the diffusion welding head after welding, which may affect the subsequent welding.

[0043] After welding is completed, when the support guide rail 5 is reset, the second rack 804 moves in the opposite direction, and the second fixing ring 905 and the second sealing rod 906 near the position of the liquid storage tank 901 inside the liquid storage cylinder 902 are in an open state, and the anti-sticking agent is replenished inside the liquid storage cylinder 902, while the first fixing ring 705 and the first sealing rod 706 near the position of the flushing nozzle 704 inside the water storage cylinder 702 are in an open state, and the flushing nozzle 704 sprays water to flush the waste chips generated by the welding on the surface of the upper diffusion welding head 2 and the lower diffusion welding head 4, so as to avoid the welding waste chips remaining on the diffusion welding head and affecting the next use.

[0044] The coating assembly 9 includes: a liquid storage tank 901 fixedly mounted on the main body 1, a liquid storage cylinder 902 fixedly mounted on the liquid storage tank 901, a second piston rod 903 for pushing the anti-sticking agent inside the liquid storage cylinder 902 to be coated on the copper laminate, and one end of the second piston rod 903 is fixedly connected to the other end of the second rack 804, a coating nozzle 904 fixedly mounted on the liquid storage cylinder 902, and a second fixing ring 905 fixedly mounted at both ends inside the liquid storage cylinder 902, a second blocking rod 906 for blocking the second fixing ring 905, the inner ring of the second fixing ring 905 is set as a conical hole, and one end of the second blocking rod 906 is set as a cone matching the conical hole on the second fixing ring 905 to improve the blocking effect between the two, and a second spring 907 to drive the second blocking rod 906 to reset.

[0045] The second spring 907 is sleeved on the surface of the second blocking 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 blocking rod 906. When the second piston rod 903 squeezes the anti-sticking agent inside the liquid storage cylinder 902, the second blocking rod 906 near one end of the coating nozzle 904 and the second fixing ring 905 are in an open state, and the anti-sticking agent passes through the gap between the second blocking rod 906 and the second fixing ring 905, and is sprayed from the coating nozzle 904 to coat the upper and lower surfaces of the copper laminations with the anti-sticking agent, which can ensure that after welding, the diffusion welding head and the copper bar are completely separated and will not stick together, and the second blocking rod 906 near one end of the liquid storage tank 901 and the second fixing ring 905 are elastically reset by the second spring 907, so that the second blocking rod 906 is pressed and fitted on the inner ring of the second fixing ring 905 for sealing.

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

[0047] The surface of the main body 1 is fixedly mounted with a fence 101. The fence 101 is provided to block the sprayed water and anti-adhesive agent, so that they can flow to the inside of the collection box 10 through the through slot 102 for collection.

[0048] Working principle: Turn on the power supply. When using the copper busbar welding machine, place the copper stack on the surface of the support rail 5. When the electric push rod 501 drives the support rail 5 to move the positions of the upward diffusion welding head 2 and the lower 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 slidably installed on the support rail 5 to move downward, so that the positioning member 601 at the top of the lifting frame 602 is pressed on the copper stack, so as to automatically clamp and fix the copper stack. At the same time, the connecting block 805 fixed on the surface of the support 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 toward the position of the gear shaft 802, so that the first fixed ring 705 and the first blocking rod 706 near one end of the water storage tank 701 are in an open state, and the water in the water storage tank 701 flows into the water storage cylinder 702 through the gap for storage, and through linkage, the other end of the second rack 804 squeezes the anti-sticking agent stored in the liquid storage cylinder 902, so that the second blocking rod 906 and the second fixed ring 905 near one end of the coating nozzle 904 are in an open state, and the anti-sticking agent passes through the gap between the second blocking rod 906 and the second fixed ring 905, and is sprayed from the coating nozzle 904 to coat the upper and lower surfaces of the moving copper stack, which can ensure that after welding, the diffusion welding head and the copper bus are completely separated and will not stick together, and then the upper diffusion welding head 2 is pushed downward by the output end of the hydraulic cylinder 3 to weld the copper stack between the upper diffusion welding head 2 and the lower diffusion welding head 4;

[0049] After welding, when the support guide rail 5 is reset, the second rack 804 moves in the opposite direction, and the second fixing ring 905 and the second sealing rod 906 near the position of the liquid storage tank 901 inside the liquid storage cylinder 902 are in an open state, and the anti-sticking agent is replenished inside the liquid storage cylinder 902.
