[0002] Automotive soft copper busbars are a common conductive component used in automotive circuit systems. They are primarily used to transmit high currents and possess excellent flexibility and conductivity. They are made by stacking individual copper foil sheets and then pressure-welding their ends. The specific pressure welding process is diffusion welding, where high temperature and high pressure form copper molecules on the surface, which then diffuse and fuse with each other. Typically, a medium-frequency diffusion welder can be used for welding. The finished soft copper busbar can be swung and rotated after welding, and its ability to bend and twist arbitrarily improves the product's installation speed and practicality.

[0028] like Figures 1 to 9 As shown, it shows a medium frequency diffusion welding machine for automotive soft copper busbars in one embodiment of the present invention. Some examples include: The bottom plate 1, the top of the bottom plate 1 is fixedly connected to the diffusion welding machine body 2, the column 3 and the quenching box 11, the column 3 is located on the front of the diffusion welding machine body 2, and the top of the column 3 is rotatably connected to the transmission column 4; Multiple extension plates 5 are evenly fixedly connected to the outside of the transmission column 4. The end of the extension plate 5 away from the transmission column 4 is rotatably connected to the support shaft 6. The outside of the support shaft 6 is fixedly connected to the load-bearing plate 7. The middle of the load-bearing plate 7 is provided with a copper bar limiting assembly 8. The copper bar limiting assembly 8 is used to cooperate with the load-bearing plate 7 to position the automobile soft copper bar; Adjustment assembly 9, which is assembled between the extension plate 5 and the support shaft 6, is used to cooperate with the bearing plate 7 to drive the copper bar limiting assembly 8 to tilt to complete the quenching of the automobile soft copper bar; The driving assembly 10 is assembled between the column 3 and the transmission column 4 and is used to cooperate with the transmission column 4 to form a continuous feeding of the diffusion welding machine body 2; In this embodiment, the diffusion welding machine body 2 at least includes: Medium frequency power supply system: used to generate medium frequency current with a frequency range of 1kHz to 100kHz; Control system: used to control the welding process, including the setting and adjustment of welding parameters; Welding head: The welding head is the part that applies pressure and heat, and consists of one or more heating elements and a clamping device; When the diffusion welding machine body 2 is in operation, the copper busbar stop assembly 8 of the automobile soft copper busbar is delivered to the welding head of the diffusion welding machine body 2 through the rotation of the transmission column 4. A certain pressure is applied to the workpiece, and then the medium-frequency power supply system generates an intermediate-frequency current. This current is transmitted to the automobile soft copper busbar through the welding head. Due to the skin effect of the intermediate-frequency current, heat is mainly concentrated on the surface of the workpiece, causing the welding area to be quickly heated to the welding temperature. As the temperature rises, the atomic activity in the welding area of the automobile soft copper busbar intensifies, and diffusion occurs between them. When a certain temperature and time are reached, the atoms in the welding area diffuse with each other and form metallic bonds, thus achieving welding. This is a mature existing technology and will not be elaborated on here. For example, Figures 4 to 6 As shown, the copper busbar limiting assembly 8 includes: The support plate 12 is fixedly connected to the middle of the bearing plate 7. Both ends of the support plate 12 are rotatably connected to the limit shaft 13. The outer side of the limit shaft 13 is fixedly connected to the limit frame 14. One end of each of the two limit shafts 13 is fixedly connected to the eccentric plate 15. The screw sleeve 16 is vertically fixedly connected to the middle part of the bearing plate 7. The internal thread of the screw sleeve 16 is connected to the transmission screw 17. The outer side of the transmission screw 17 is rotatably connected to the displacement plate 18. Both ends of the displacement plate 18 are rotatably connected to the linkage rods 19, and the two linkage rods 19 are rotatably connected to the two eccentric plates 15 respectively. The push box 20 is fixedly connected to the bottom end of the carrying plate 7. The bottom end of the push box 20 is vertically slidably connected to a push rod 21. One end of the push rod 21 located inside the push box 20 is fixedly connected to a push plate 22. The bottom end of the push rod 21 is fixedly connected to the carrying plate, and the bottom end of the transmission screw 17 is also rotatably connected to the carrying plate. In this embodiment, the assembly position of the transmission screw 17 and the displacement plate 18 is a polished rod, so the displacement plate 18 can form a stable rotation connection with the transmission screw 17 and will not be affected by the thread of the transmission screw 17; For example, Figure 4 As shown, the limiting frame 14 includes: Two support rods, the two support rods are respectively fixedly connected to the two ends of the limiting shaft rod 13, and a contact rod is fixedly connected between the ends of the two support rods away from the limiting shaft rod 13. The contact rod is circular. Through the circular structure of the contact rod, after the contact rod is flipped, it can smoothly contact with the soft copper busbar of the car, thereby ensuring the positioning effect of the contact rod; For example, Figure 5As shown, the end of the eccentric plate 15 away from the limiting shaft 13 is fixedly connected to the positioning rod, and the end of the linkage rod 19 away from the displacement plate 18 is rotatably connected to the positioning rod. Through the setting of the positioning rod, an effective assembly can be formed with the end of the linkage rod 19 to ensure the stability of the linkage of the linkage rod 19 between the displacement plate 18 and the eccentric plate 15. For example, Figure 7 As shown, the adjustment component 9 includes: A transmission worm gear 23 is fixedly connected to one end of the support shaft 6. The end of the support shaft 6 close to the transmission worm gear 23 is fixedly connected to a transmission frame 24. The top of the transmission frame 24 is rotatably connected to a transmission shaft A25. The two ends of the transmission shaft A25 are respectively fixedly connected to a transmission worm 26 and a transmission spur gear 27, and the transmission worm 26 is meshed with the transmission worm gear 23. A stabilizing shaft 28 is slidably connected to one end of the transmission frame 24. An end of the stabilizing shaft 28 close to the transmission shaft A25 is fixedly connected to a stabilizing plate 29. A coil spring 30 is fixedly connected between the stabilizing plate 29 and the transmission frame 24. The transmission rod 31 is slidably connected to one end of the transmission frame 24. The end of the transmission rod 31 close to the transmission shaft A25 is fixedly connected to the pressure block 32. The end of the transmission rod 31 away from the transmission shaft A25 is fixedly connected to the transmission plate 33. The end of the transmission plate 33 away from the transmission rod 31 is also fixedly connected to the stabilizing shaft 28. The power assembly is mounted on the outside of the column 3 and is used to cooperate with the transmission spur gear 27 to drive the transmission shaft A25 to rotate; In this embodiment, the power assembly is adapted to the position of the quenching box 11; For example, Figure 7 As shown, the stabilizing plate 29 is arc-shaped, and an anti-slip groove is provided on the side of the stabilizing plate 29 close to the transmission shaft A25. Through the structural characteristics of the stabilizing plate 29, the stabilizing plate 29 can contact the outer side of the transmission shaft A25 to a greater extent, thereby ensuring the application effect of the stabilizing plate 29; For example, Figure 8 As shown, the power assembly includes: Transmission frame B34, which is fixedly connected to the outside of the column 3. One end of the transmission frame B34 is fixedly connected to the hydraulic cylinder 35, and the output end of the hydraulic cylinder 35 is fixedly connected to the push plate 36; The transmission rack 37 is fixedly connected to the top of the push plate 36, and the transmission rack 37 is meshed with the transmission spur gear 27. The side of the transmission rack 37 away from the transmission shaft A25 is fixedly connected to the extrusion plate 38 for extruding the pressure block 32; For example, Figure 9As shown, a linear guide rod is vertically slidably connected to the middle of the transmission frame B34, and the top end of the linear guide rod is fixedly connected to the push plate 36. The arrangement of the linear guide rod can provide effective guidance for the displacement of the push plate 36, thereby avoiding uncontrollable deviation when the transmission rack 37 and the transmission spur gear 27 are engaged, thereby greatly improving the transmission stability of the transmission rack 37. For example, Figure 7 and Figure 8 As shown, an extrusion slope is provided on the side of the extrusion plate 38 away from the transmission rack 37, and a compression slope adapted to the extrusion slope is provided on the end of the pressure block 32 close to the extrusion slope. Through the setting of the extrusion slope and the compression slope, when the transmission rack 37 is vertically displaced, the extrusion slope will come into contact with the compression slope. With the continuous displacement of the transmission rack 37, the extrusion plate 38 can push the pressure block 32, and under the linkage of the conduction plate 33, the stabilization plate 29 is urged to move away from the transmission shaft A25, thereby forming a rotation unlocking of the transmission shaft A25.
[0029] For example, Figure 8 As shown, the drive assembly 10 includes: Transmission frame C39, which is fixedly connected to the outside of the column 3. The bottom end of the transmission frame C39 is fixedly connected to a reducer 40. The power output end of the reducer 40 is fixedly connected to a driving spur gear 41. The outside of the transmission column 4 is fixedly connected to a reduction spur gear 42, and the reduction spur gear 42 is meshed with the driving spur gear 41. The drive motor 43 is fixedly connected to the bottom end of the reducer 40, and the output end of the drive motor 43 is fixedly connected to the power input end of the reducer 40; In this embodiment, the number of extension plates 5 is four, among which the front end position of the base plate 1 is the loading station, and the angles between two adjacent extension plates 5 are 90°. At the same time, the number of teeth of the reduction spur gear 42 is 4 times the number of teeth of the driving spur gear 41. Then, when the reducer 40 drives the driving spur gear 41 to rotate one circle, the reduction spur gear 42 will drive the transmission column 4 to rotate a quarter of a circle, so that the extension plates 5 can reach the working position of the diffusion welding machine body 2 in sequence.
[0030] Working principle: first, the bearing plate 7 on the arrival of the loading station is placed on the automobile soft copper row, then the transmission screw 17 is rotated, the transmission screw 17 can be screwed in the screw sleeve 16 under the connection of the transmission screw 17 and the screw sleeve 16, and because the displacement plate 18 is assembled outside the transmission screw 17, when the transmission screw 17 is screwed in, the vertical height of the displacement plate 18 can be adjusted, and under the rotary connection of the displacement plate 18 and the transmission screw 17, the displacement plate 18 cannot rotate with the transmission screw 17 under the limitation of the linkage rod 19, because the linkage rod 19 is connected between the displacement plate 18 and the eccentric plate 15, when the displacement plate 18 moves down, the limiting shaft 13 can be rotated by the eccentric plate 15, prompting the limiting frame 14 to approach the automobile soft copper row, when the limiting frame 14 contacts the automobile soft copper row on the bearing plate 7, the positioning of the automobile soft copper row is completed; Start the drive motor 43 and transmit the power of the drive motor 43 to the drive spur gear 41 through the speed reducer 40, prompting the drive spur gear 41 to move the speed reduction spur gear 42, when the drive spur gear 41 rotates one circle, the transmission column 4 will rotate one fourth of a circle, so that the clamped automobile soft copper row can be transmitted to the direction of the diffusion welding machine body 2, at the same time, the next bearing plate 7 will reach the loading station, then personnel continue to clamp the automobile soft copper row at the bearing plate 7; When the bearing plate 7 carrying the automobile soft copper row reaches the diffusion welding machine body 2, start the diffusion welding machine body 2 to weld the automobile soft copper row, and because the automobile soft copper row is limited by the bearing plate 7 and the limiting frame 14 during welding, the stability during welding can be ensured, and misalignment is avoided; After the automobile soft copper row is welded, continue to start the drive motor 43 to drive the transmission column 4 to rotate one fourth of a circle, so that the welded automobile soft copper row can reach above the quenching tank 11, at the same time, the next bearing plate 7 will reach the working position of the diffusion welding machine body 2 for processing; For the bearing plate 7 reaching above the quenching tank 11, the hydraulic cylinder 35 can be started to push the transmission rack 37 upward by the pushing plate 36, with the continuous displacement of the transmission rack 37, the pressing plate 38 will be in contact with the pressure block 32, and the pressure block 32 will slide under the limitation of the transmission rod 31, under the connection of the transmission plate 33 and the stabilizing shaft 28, the transmission rod 31 can be slid to drive the stabilizing plate 29 to move away from the transmission shaft A25 under the limitation of the stabilizing shaft 28, so as to reduce the friction of the transmission shaft A25 rotation, and the rotation of the transmission shaft A25 is unlocked; As the transmission rack 37 continues to move upward, the transmission rack 37 will be connected to the transmission spur gear 27 and the transmission spur gear 27 will be moved. Since the transmission spur gear 27 is supported by the transmission shaft A25, it can drive the transmission shaft A25 to rotate, and move the transmission worm gear 23 through the transmission worm 26, prompting the support shaft 6 to drive the bearing plate 7 to flip downward, so that the welded automobile soft copper busbar is immersed in the liquid inside the quenching box 11, quenching the automobile soft copper busbar, and making the welding part of the automobile soft copper busbar harden quickly. After quenching, the hydraulic cylinder 35 is started to pull the transmission rack 37 downward, prompting the transmission rack 37 to disengage from the transmission spur gear 27. Since the stabilizing plate 29 is displaced, the coil spring 30 can be deformed. When the extrusion plate 38 is separated from the pressure block 32, the elastic potential energy of the coil spring 30 can be used to prompt the stabilizing plate 29 to fit closely with the transmission shaft A25, forming a rotation limit of the transmission shaft A25.
[0031] Subsequently, as the drive motor 43 is restarted, the quenched automobile soft copper busbar can be transferred to the loading station. Then the personnel reversely rotate the transmission screw 17 to prompt the displacement plate 18 to move up, and under the linkage of the linkage rod 19, the eccentric plate 15 and the limit shaft 13, the limit frame 14 is flipped upward to release the limit on the automobile soft copper busbar. At the same time, in the process of the transmission screw 17 moving upward, the setting of the carrying plate can be used to prompt the push plate 22 to contact the bottom surface of the automobile soft copper busbar, and finally the automobile soft copper busbar is pushed out of the carrying plate 7, and then the automobile soft copper busbar is removed from the carrying plate 7, and the unsoldered automobile soft copper busbar is clamped on the carrying plate 7 and waits for transfer.
