Description

Technical Field

[0002] In the current field of flexible copper busbar processing, it is necessary to weld multiple layers of copper foil to form flexible copper busbars. Traditional welding equipment has revealed many problems that urgently need to be solved in practical applications.

[0003] In terms of welding precision, existing equipment struggles to meet production standards. Multi-layer copper foil welding demands extremely high precision, but traditional equipment, due to structural and control limitations, is prone to positional deviations and uneven strength during welding, resulting in low product yield and increased costs. In scenarios with stringent electrical performance requirements, such as new energy vehicle battery connection systems, low welding precision can even pose safety hazards.

However, existing equipment can only weld and cannot drill simultaneously. Companies are forced to purchase two separate sets of equipment, which not only occupies significant production space but also increases procurement and maintenance costs. Furthermore, operating the two steps on separate equipment significantly prolongs the production process, reduces production efficiency, and hinders the company's competitiveness in the market.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figures 1 to 4 As shown, this utility model discloses a flexible copper busbar welding device for welding and punching the ends of multiple copper foils. Specifically, it employs a diffusion welding process to ultimately form a flexible copper busbar. The aforementioned flexible copper busbar welding device includes a lower welding mechanism 10 and an upper welding mechanism 20. The lower welding mechanism 10 includes a first connecting seat 11, a first heating seat 12 located at the upper end of the first connecting seat 11, and a first fixture 13 fixed to the upper end of the first heating seat 12. The center of the first heating seat 12 is provided with a waste trough 121, and the first fixture 13 is provided with a positioning groove 131. The positioning groove 131 has a waste hole 132 that penetrates the first fixture 13 and communicates with the waste trough 121. The upper welding mechanism 20 includes a second connecting seat 21, a second heating seat 22 located at the lower end of the second connecting seat 21, and a second fixture 23 fixed at the lower end of the second heating seat 22; the lower end face of the second fixture 23 is provided with a protrusion 231, and the protrusion 231 is provided with a shape and size corresponding to the positioning groove 131; the second connecting seat 21 is embedded with a punching module 30, and the punching module 30 extends to provide a punching head 31 that penetrates the second fixture 23 vertically; the top of the second connecting seat 21 is provided with a downward driving element 40.

[0032] During operation, the first heating seat 12 heats the first fixture 13, and the second heating seat 22 heats the second fixture 23. The operator stacks multiple copper foils and places them into the positioning groove 131, which is rectangular and serves to position the copper foils, ensuring the accuracy of subsequent welding and drilling. The downward driving element 40 drives the upper welding mechanism 20 to move vertically downwards, causing the second fixture 23 to close with the first fixture 13. Specifically, the protrusion 231 of the second fixture 23 extends into the positioning groove 131 of the first fixture 13 and presses the copper foils together. Under the high temperature of the first fixture 13 and the second fixture 23, the multiple layers of copper foil undergo diffusion welding within the positioning groove 131. During this process, the downward driving element 40 continuously applies downward pressure (diffusion welding is a welding process in which the workpiece undergoes microscopic plastic deformation at the tiny unevenness of the two welding surfaces under high temperature and high pressure, achieving close contact), thereby welding the multiple layers of copper foil into a flexible copper busbar. After welding is completed and the device has cooled for a certain period of time, the drilling module 30 drives the drilling head 31 to move vertically downwards to drill holes in the flexible copper busbar. The waste material generated during drilling enters the waste tank 121 through the waste material hole 132. This utility model's flexible copper busbar welding device integrates welding and drilling functions, and its reasonable structural design simplifies the production process and improves the production efficiency of flexible copper busbars.

[0033] Specifically, both the outer walls of the first heating seat 12 and the second heating seat 22 are provided with winding grooves 122, and heating coils 123 are wound inside the winding grooves 122. When the heating coils 123 are energized, the first heating seat 12 and the second heating seat 22 are heated based on the principle of eddy current heating. In addition, the first fixture 13 and the second fixture 23 are made of graphite material with excellent thermal conductivity. The heat from the first heating seat 12 and the second heating seat 22 is conducted to the first fixture 13 and the second fixture 23, thereby heating the copper foil.

[0034] Specifically, the opposing surfaces of the first connecting seat 11 and the second connecting seat 21 are each provided with a connecting base 111, and the two sides of the first fixture 13 and the second fixture 23 are each provided with a connecting plate 133. It also includes a locking bolt 14. The connecting plate 133 has a strip hole 134, and the connecting base 111 has a connecting hole 112. The locking bolt 14 passes through the strip hole 134 and the connecting hole 112 in sequence, realizing the assembly connection of the first fixture 13 with the first connecting seat 11, the second fixture 23 and the second connecting seat 21. The strip hole 134 is used to make the first fixture 13 and the second fixture 23 adjustable to adapt to different positions of the connecting base 111.

[0035] Specifically, a vision sensor 50 is provided on the side of the lower welding mechanism 10. The sensing end of the vision sensor 50 is set towards the first fixture 13. The vision sensor 50 can sense the closing of the first fixture 13 and the second fixture 23 to ensure the normal progress of diffusion welding.

[0036] Specifically, the downward pressure drive element 40 can be selected from either a pneumatic cylinder or a hydraulic cylinder according to the required downward pressure. When a larger downward pressure is required, a hydraulic cylinder is selected, and vice versa. Furthermore, a telescopic shaft 41 extends from the lower end of the downward pressure drive element 40, and a connecting plate 42 is provided at the top of the second connecting seat 21. The bottom end of the telescopic shaft 41 is fixedly connected to the connecting plate 42. This structure improves the structural strength of the connection between the downward pressure drive element 40 and the upper welding mechanism 20. Simultaneously, a cover 60 is provided on the outer side of the downward pressure drive element 40, and the telescopic shaft 41 passes through the cover 60. The cover 60 protects the downward pressure drive element 40 and extends the service life of the equipment. The top of the connecting plate 42 is provided with guide posts 43 arranged in a circular array around the telescopic shaft 41, and the bottom of the cover 60 is provided with a guide sleeve 44. The guide posts 43 cooperate with the guide sleeve 44 to ensure the vertical movement of the upper welding mechanism 20.

[0037] Specifically, the bottom of the lower welding mechanism 10 is provided with a support platform 70, which increases the height of the lower welding mechanism 10 and makes it easier for operators to operate.

[0038] Compared to existing technologies, the flexible copper busbar welding device of this utility model is provided with a lower welding mechanism 10 and an upper welding mechanism 20. The lower pressure driving element 40 of the upper welding mechanism 20 drives the second fixture 23 to close tightly with the first fixture 13 to perform diffusion welding on the copper foil, while applying pressure to ensure welding quality and form a flexible copper busbar. At the same time, the upper welding mechanism 20 is provided with a drilling module 30, which can drill holes in the flexible copper busbar, integrating welding and drilling functions, reducing the size of the equipment, and improving the production and processing efficiency of the flexible copper busbar. In addition, the positioning groove 131 of the first fixture 13 and the protrusion 231 of the second fixture 23 cooperate to ensure the welding and drilling accuracy of the flexible copper busbar. The first heating seat 12 and the second heating seat 22 use the eddy current heating of the heating coil 123 to ensure welding efficiency.

[0039] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
