Description

Technical Field

[0001] The invention relates to the technical field of soft-package copper busbar assembly, in particular to a soft-package copper busbar automatic assembly device. Background Art

[0002] Soft-coated copper busbar is a flexible conductive connection component made of multiple layers of copper foil (usually 0.1 to 0.3 mm thick) through lamination, welding or crimping. Compared with traditional hard copper busbars, soft-coated copper busbars have higher flexible bending ability, vibration absorption ability and spatial adaptability. They are widely used in new energy batteries, electric vehicles, energy storage systems, high-voltage busbar connections, server power supply systems and other fields. The polymer diffusion welding process is an important part of the production process of soft copper busbars. Molecular diffusion welding is a special welding process. The polymer diffusion welding machine is a welding device that tightly fits the weldment for a period of time under a certain temperature and pressure, so that the atoms between the contact surfaces diffuse with each other to form a connection. It can weld copper foils of different strengths together in a specific area. The copper foil soft connection welding process does not require the use of any form of flux.

[0003] After searching, the invention patent with publication number CN114227042A discloses a welding machine and method for welding soft copper busbars of batteries, which reduces labor costs, reduces the rate of human errors, improves the neatness of copper busbar stacking, and increases the qualified rate of copper busbar welding.

[0004] In the existing scheme, when the copper foil workpiece is input into the welding chamber, there is a misalignment of multiple layers of copper foil, which will cause no contact in some areas, resulting in incomplete welding and affecting the conduction efficiency. During the hot pressing process, if the copper foils are misaligned, it will not only cause welding failure, but may also form warping deformation during the cooling stage, reducing the flexibility of the copper busbar; and the copper foil in the middle fails to absorb heat in time due to uneven thermal conductivity, resulting in insufficient heating or uneven temperature gradient.

[0038] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, describe in detail the specific implementation manners, structures, features, and effects of the present invention.

[0039] Please refer to Figures 1 - 7As shown in the figure, the present invention provides a soft-pack copper row automatic assembly device, which includes an assembly chamber 1 provided on a substrate. A linear slide 3 is provided through the inner cavity of the assembly chamber 1 along the feeding port and discharging port directions. And a welding unit for assembling copper foils is provided inside the assembly chamber 1. Both ends of the linear slide 3 are connected with brackets, and a clamping station for defining different copper foils is slidably provided on the linear slide 3. Transfer units for feeding and discharging the clamping station are provided on both sides of the assembly chamber 1;

[0040] The clamping station includes a first positioning frame 4 and a second positioning frame 8. The first positioning frame 4 and the second positioning frame 8 are fixed through a connecting plate. Two simultaneously moving pressing plates 12 are slidably provided inside the first positioning frame 4. And a calibration unit for aligning multiple copper foils is slidably provided on the side of the first positioning frame 4 away from the driving end of the pressing plate 12. A placement groove 13 for positioning and placing the copper row is provided between each pressing plate 12 and the inner wall surface of the corresponding side of the first positioning frame 4. And a clamping member is provided on the surface of the pressing plate 12 facing the placement groove 13. A limiting unit for carrying and assembling the copper foil is provided at the bottom of the inner cavity of the placement groove 13;

[0041] The limiting unit includes electric push rods two 25 provided on the outer wall surface of the first positioning frame 4 and the surface of the pressing plate 12. The pushing end of one electric push rod two 25 is connected with a support plate 26 sliding at the bottom of the first positioning frame 4. The support plate 26 connected by the other electric push rod two 25 slides at the bottom of the pressing plate 12. A pushing portion is provided at the end of the support plate 26;

[0042] The calibration unit includes a push plate 14, and two calibration members for cooperating with the placement groove 13 are installed on the side surface of the push plate 14;

[0043] As Figure 1 and Figure 3 shown, the first positioning frame 4 is exposed outside the assembly chamber 1. First, the transfer unit adsorbs and inputs the copper foil workpiece wrapped with a polymer film to the first positioning frame 4 at a fixed point. And the second positioning frame 8 is located inside the assembly chamber 1. Multiple copper foil workpieces in the second positioning frame 8 are subjected to heating, pressurization and solid-state diffusion by the welding unit. During the welding process of the polymer film, through the change of the molecular structure, the wettability of the copper surface is improved, making it easier for atomic diffusion on the copper foil surface, increasing the contact area between the copper foil and the polymer film, and enhancing the effect of diffusion welding to ensure that a firm metal connection can be formed between the copper foil layers;

[0044] It should be noted that when inputting the copper foil workpiece, the two pressing plates 12 in the middle of the inner cavity of the positioning frame 1-4 are in a state of approaching each other, and the two supporting plates 26 are in a state of approaching each other in the corresponding placing grooves 13, which facilitates loading the copper foil workpiece onto the two supporting plates 26 in the placing grooves 13. After multiple copper foils are loaded into the corresponding placing grooves 13, the two pressing plates 12 approach each other, synchronously driving the movement of the supporting plates 26 on the corresponding sides. By limiting the sides of multiple copper foils with the pressing plates 12, and then the correcting member of the correcting unit pushes one end of multiple copper foil workpieces, making them abut against the inner wall surface of the positioning frame 1-4, so that they are stable in the positioning frame 1-4 or the positioning frame 2-8. At this time, multiple copper foils are aligned in the vertical direction, and their end faces are kept consistent, improving the alignment accuracy of the copper foils, ensuring the maximum contact area of the welding area, and improving the welding consistency;

[0045] During polymer welding, the positioning frame 1-4 and the positioning frame 2-8 enter the assembly room 1 in sequence for alternate welding. The positioning frame 1-4 and the positioning frame 2-8 weld different copper foils respectively, improving the applicability. When the positioning frame 1-4 is welding, the positioning frame 2-8 is in the gap of loading materials at this time. During each welding, there is no need to stop the machine for loading and unloading materials, improving the welding efficiency;

[0046] The two supporting plates 26 in the same placing groove 13 are opened by the control of the electric push rod 2-25 on the corresponding side, facilitating the copper foil in the placing groove 13 to enter the welding unit for welding;

[0047] After welding is completed, the copper row is loaded into the corresponding placing groove 13 by using the pushing part of the supporting plate 26, completing the grasping of the copper row, and facilitating its discharging and moving out of the assembly room 1.

[0048] Refer to Figure 7 As shown, the clamping member includes a sliding clamping plate 28 arranged in the cavity groove of the pressing plate 12. A spring 1-29 is arranged at the upper end of the sliding clamping plate 28. One end of the spring 1-29 is fixed to the cavity groove. The inner side of the sliding clamping plate 28 is elastically connected with a limiting plate 16;

[0049] A spring 2-30 is arranged between the limiting plate 16 and the sliding clamping plate 28. The upper part of the side surface of the limiting plate 16 is provided with an outwardly protruding inclined part 1-17, and the bottom part of the side surface of the limiting plate 16 is provided with an inwardly protruding inclined part 2-27. The opening directions of the inclined part 2-27 and the inclined part 1-17 are different;

[0050] The pressing plate 12 moves towards the sides of multiple copper foils on the corresponding side. At this time, the inclined part 2-27 at the lower part of the limiting plate 16 presses the upper copper foil. At this time, the limiting plate 16 drives the sliding clamping plate 28 to slide in the cavity groove of the pressing plate 12, and elastically compresses the spring 1-29, limiting multiple copper foils in the placing groove 13 to ensure the relative positions of each layer of copper foils are consistent;

[0051] When the welding unit contacts the inclined portion 17 of the first one, the limit plate 16 slides on the sliding clamping plate 28 at this time and elastically compresses the first spring 29, which does not affect the progress of polymer welding;

[0052] Diffusion welding is mainly based on the contact and combination of material molecules.

[0053] Refer to Figure 6 As shown, the correction part includes a telescopic column 23 installed on the push plate 14. The telescopic end of the telescopic column 23 is connected with a correction plate 22, and a return spring is sleeved outside the telescopic column 23. An electric push rod 24 for pushing the push plate 14 to move is arranged on the inner wall surface of the first positioning frame 4. After the copper foil is loaded into the corresponding placement groove 13, the side of the copper foil is first limited by the extrusion plate 12, and then the electric push rod 24 pushes the push plate 14 and its correction plate 22 towards the end face of the copper foil until the telescopic column 23 expands and contracts and compresses the return spring, so that the positions of multiple copper foils are kept consistent, improving the welding accuracy.

[0054] Refer to Figure 4 As shown, a clamping cylinder 15 is installed in the middle of the inner wall surface of the first positioning frame 4, and the two driving ends of the clamping cylinder 15 are fixed to the extrusion plates 12 on the corresponding sides;

[0055] Infrared heating plates 18 for heating the copper foil in the middle position are arranged on the inner wall surface of the first positioning frame 4 and the surface of the extrusion plate 12;

[0056] The copper foil in the middle position is heated by the infrared heating plate 18 to ensure that the middle copper foil can reach a suitable temperature for diffusion welding, preventing the problem of poor welding effect caused by uneven heating of the welding unit.

[0057] Refer to Figure 2 As shown, a pushing unit 11 is installed on the top surface of the inner cavity of the assembly room 1, and a closing plate 2 for blocking the feeding port and the discharging port is connected to the pushing end of the pushing unit 11;

[0058] The welding unit includes a lower pressing plate 9 that fits and contacts the lower surfaces of the first positioning frame 4 and the second positioning frame 8. An upper pressing plate 10 is arranged to lift above the lower pressing plate 9. When two of the supporting plates 26 are opened, the lower-layer copper foil fits on the top surface of the lower pressing plate 9, and then the upper pressing plate 10 descends into the corresponding placement groove 13 to perform polymer welding on the multiple copper foils in the placement groove 13.

[0059] Refer to Figure 1 and Figure 5 As shown, feeding belts 5 are arranged at both ends of the linear slide 3, and a discharging belt 7 is arranged in the feeding direction of the linear slide 3 away from the first positioning frame 4. The transfer unit is installed between the first positioning frame 4 and the discharging belt 7;

[0060] The transfer unit includes a rotating frame 6 rotatably arranged on the substrate. A linear slide rail 19 is provided on the lower surface of the rotating frame 6. A rotating motor 20 is installed on the slide block of the linear slide rail 19. An adsorption plate 21 for fixing the copper foil is arranged on the driving end of the rotating motor 20 in a lifting manner.

[0061] Through the adsorption plate 21 in the transfer unit, and then driven by the rotating motor 20, the position of the copper foil is finely adjusted. The direction is changed by the rotating rotating frame 6, and the copper foil in the loading tape 5 is input to the position corresponding to the positioning frame 1 4. Then, the copper foil is input into different placing grooves 13 in the positioning frame 1 4 through the linear slide table 3 to complete the loading. After the welding is completed, it is output to the unloading tape 7 through the transfer unit.

[0062] When the present invention is in use, by setting the limiting unit and the correction unit, the two pressing plates 12 in the middle of the inner cavity of the positioning frame 1 4 are in a state of approaching each other, and the two supporting plates 26 are in a state of approaching each other in the corresponding placing grooves 13, which is convenient for loading the copper foil workpiece onto the two supporting plates 26 in the placing grooves 13. When multiple copper foils are loaded into the corresponding placing grooves 13, then the two pressing plates 12 approach each other, synchronously driving the movement of the corresponding supporting plates 26 on the same side. The sides of multiple copper foils are limited by the pressing plates 12, and then the correcting member of the correction unit pushes one end of multiple copper foil workpieces, making them abut against the inner wall surface of the positioning frame 1 4, so that they are stable in the positioning frame 1 4 or the positioning frame 2 8. At this time, multiple copper foils are aligned in the vertical direction, and their end faces are kept consistent, improving the alignment accuracy of the copper foils, ensuring that the contact area of the welding area is maximized, improving the consistency of welding. After welding, the copper busbar is loaded into the corresponding placing groove 13 by the pushing part of the supporting plate 26 to complete the grasping of the copper busbar, which is convenient for its discharging and moving out of the assembly room 1;

[0063] The limiting plate 16 drives the sliding clamping plate 28 to slide in the cavity groove of the pressing plate 12, and elastically compresses the first spring 29, limiting multiple copper foils in the placing groove 13 to ensure that the relative positions of each layer of copper foil are consistent; The upper pressing plate 10 in the welding unit contacts the first inclined part 17. At this time, the limiting plate 16 slides on the sliding clamping plate 28 and elastically compresses the first spring 29, which does not affect the progress of polymer welding.

[0064] The middle copper foil is heated by the infrared heating plate 18 to ensure that the middle copper foil can reach a suitable temperature for diffusion welding, preventing poor welding effect caused by uneven heating of the welding unit and improving the heat transfer efficiency.

[0065] The above are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention.
