A material buffer device 33 is provided between the slitting device 1 and the unloading device 2.

[0035] Through the above technical scheme, the present invention cuts the raw material copper and aluminum foil roll into multiple copper and aluminum foil strips along the winding direction through the strip cutting device 1, and then feeds it into the unloading device 2. The multiple copper and aluminum foil strips are pulled, fed and cut by the cutting device 6 of the stacking device 3.

[0036] Embodiment 2:

[0037] like Figure 1-Figure 13 As shown, the copper-aluminum foil flexible busbar welding fully automatic unloading production line is a highly efficient automated equipment developed to improve the production efficiency of copper-aluminum foil flexible busbars. The production line consists of multiple functional modules, including a strip cutting device 1 and a unloading device 2. First, the raw material copper-aluminum foil roll is cut by the strip cutting device 1, and the cut copper-aluminum foil strips will be further stacked and welded in the production process.

[0038] The main function of the strip cutting device 1 is to cut the copper-aluminum foil roll into multiple copper-aluminum foil strips according to the set width. In this process, the strip cutting device 1 cuts along the direction of the copper-aluminum foil roll. After the strip cutting is completed, the generated multiple copper-aluminum foil strips will enter the unloading device 2 at the same time.

[0039] The unloading device 2 includes a stacking device 3 and a pre-welding device 4. The stacking device 3 is composed of a discharge table 5, a cutting device 6 and a feeding device 7. At this stage, the multiple copper-aluminum foil strips cut by the strip cutting device 1 are pulled into the cutting device 6. The cutting device 6 controls the pulling length of each copper-aluminum foil strip through the pulling system to ensure that the length of the copper-aluminum foil strip cut each time is consistent with the preset value. When the length of the copper-aluminum foil strip reaches the preset standard, the cutting device 6 cuts the multiple copper-aluminum foil strips at the same time. The multiple copper-aluminum foil strips that are pulled and cut are stacked and laid on the discharge table 5 in an orderly manner. This process is repeated for multiple times, and the number of repetitions is a preset value, which is used to control the number of copper-aluminum foil layers of the copper-aluminum foil soft row to meet different needs, and the stacked copper-aluminum foil strips form a complete copper-aluminum foil soft row (a semi-finished product, and the finished product needs to be welded by polymer diffusion welding).

[0040] Since multiple copper-aluminum foil strips are stacked at the same time, multiple copper-aluminum foil soft rows, namely copper-aluminum foil soft row groups, will be formed on the unloading table 5. This stacking method significantly improves production efficiency and facilitates subsequent polymer diffusion welding. As the copper-aluminum foil soft row group is formed, the feeding device 7 will start working. The feeding device 7 first clamps the two ends of the copper-aluminum foil soft row group, and then transports it to the pre-welding device 4 for subsequent processing.

[0041] The functional modules of the pre-welding device 4 include a receiving table 8, a vibrating device 9, a welding device 10, a pressing device 11 and an auxiliary material device 12. The pre-welding device 4 is symmetrically arranged and can process both ends of the copper-aluminum foil flexible row group at the same time to improve the overall welding efficiency. In the pre-welding device 4, the auxiliary material device 12 first places a nickel sheet on the receiving table 8. Then, the feeding device 7 places the two ends of the copper-aluminum foil flexible row group on two receiving tables 8 respectively (the pre-welding device 4 is symmetrically arranged).

[0042] After completing the above process, the auxiliary material device 12 will place an auxiliary copper-aluminum foil sheet on the copper-aluminum foil soft row group. Since the polymer diffusion welding will squeeze the welding part (two ends) of the copper-aluminum foil soft row during welding, and the thickness of the two ends of the copper-aluminum foil soft row must be produced according to the specifications, but during welding, if the extrusion pressure is too large, the thickness of the two ends of the copper-aluminum foil soft row will not meet the production specifications. If the extrusion pressure is too small, the welding effect of the two ends of the copper-aluminum foil soft row will deteriorate. A piece of auxiliary copper-aluminum foil sheet at both ends of the copper-aluminum foil soft row can increase the extrusion force during welding and meet the production specifications of the thickness of the two ends of the copper-aluminum foil soft row at the same time. Subsequently, the feeding device 7 will return to the stacking device 3, take another group of copper-aluminum foil soft row groups, and stack them on the auxiliary copper-aluminum foil sheet again. At this time, the auxiliary material device 12 will place another nickel sheet on the copper-aluminum foil flexible busbar group to complete the stacking operation of the copper-aluminum foil flexible busbar group (the length and width of the nickel sheet and the auxiliary copper-aluminum foil sheet are the same and equal to the width of the copper-aluminum foil flexible busbar group. The nickel sheet is used to connect each group of copper-aluminum foil flexible busbars so that multiple groups of copper-aluminum foil flexible busbars form an integral copper-aluminum foil flexible busbar group for subsequent polymer diffusion welding processing).

[0043] At the same time, the vibration device 9 and the clamping device 11 are started. The clamping device 11 cooperates with the vibration device 9, that is, the clamping device 11 is intermittently loosened to facilitate the vibration device 9 to level the copper-aluminum foil soft row group. The clamping device 11 cooperates with the vibration device 9 to level the two ends of the copper-aluminum foil soft row group to provide a flat welding surface for subsequent welding. The clamping device 11 plays a very important role in this process. By applying appropriate pressure, it ensures that the copper-aluminum foil soft row group and the auxiliary copper-aluminum foil sheet and nickel sheet are tightly fitted during the welding process.

[0044] The welding device 10 is then started to weld the sides of each copper-aluminum foil flexible row of the copper-aluminum foil flexible row group, that is, to weld vertically, and weld each copper-aluminum foil sheet together (including the nickel sheet and the auxiliary copper-aluminum foil sheet). During the welding process, the bonding between the nickel sheet, the auxiliary copper-aluminum foil sheet and the copper-aluminum foil flexible row will be enhanced, so that the three are firmly connected together. This welding method not only improves the strength of the overall structure, but also facilitates subsequent transportation and processing operations.

[0045] After welding is completed, the copper-aluminum foil soft row group will enter the polymer diffusion welding machine for final welding.

[0046] In each link of the entire production line, the automated control system will ensure the coordinated operation of each device. The system can monitor the status of each production link in real time and adjust the operating parameters in time to ensure that the entire production line operates in the best state. Data collection and analysis functions are also integrated here, which can collect and analyze various data in the production process to help managers make more accurate decisions.

[0047] This fully automated production line not only improves production efficiency, but also significantly improves the production quality of copper-aluminum foil flexible busbars. By controlling every link, it can effectively reduce the failure rate caused by human factors and ensure that each batch of products meets high quality requirements. At the same time, the design of the production line makes equipment maintenance and maintenance easier, reduces downtime during production, and improves overall production capacity.

[0048] The cutting device 6 of the present invention is located on one side of the unloading platform 5. The copper and aluminum foil strips cut by the cutting device 6 can be quickly stacked on the unloading platform 5, thereby improving the stacking speed of the copper and aluminum foil strips and improving production efficiency. The structure of the cutting device 6 is mainly composed of a feed roller group 13 and a cutting knife 14. The feed roller group 13 is driven by a driving motor and is used to pull the copper and aluminum foil strips so that they can smoothly enter the cutting process. The feed roller group 13 has an accurate length recording function and can monitor the feeding length of the copper and aluminum foil strips in real time to ensure the accuracy and consistency of the cutting. During the production process, the feed roller group 13 can accurately record the length of the copper and aluminum foil strips according to the set standards and requirements through real-time communication with the control system. When the copper and aluminum foil strips pulled by the feed roller group 13 reach a predetermined length, the cutting device 6 will automatically start the cutting knife 14 to cut, ensuring production efficiency and cutting quality. In this process, the cutting knife 14 is powered by a driving cylinder to achieve fast and accurate cutting action.

[0049] The feeding device 7 of the present invention is located above the unloading table 5, which is convenient for the feeding device 7 to take the copper-aluminum foil flexible row group stacked on the unloading table 5. The structure of the feeding device 7 mainly includes a moving frame 15 and a picking device 16. The moving frame 15 is fixedly installed with the picking device 16, and has a multi-axis moving function. The moving frame 15 adopts a three-axis moving device, which can realize horizontal movement and up and down movement. This function greatly improves the flexible operation of the picking device 16 in space. After the copper-aluminum foil flexible row group is stacked on the unloading table 5, the picking device 16 is started to pick up the material. The picking device 16 is composed of a support plate 17, a slide bar 18 and a chuck 19. The first cylinder 20 and the second cylinder 21 are fixedly installed on the support plate 17. The first cylinder 20 is connected to the slide bar 18 and is responsible for driving the horizontal movement of the slide bar 18. The second cylinder 21 is connected to the chuck 19 and is responsible for clamping the copper-aluminum foil flexible row group. During the material picking process, the first cylinder 20 is first extended, and the material picking device 16 is inserted downward so that the slide bar 18 is lower than the bottom of the copper-aluminum foil soft row group. At this time, the first cylinder 20 will retract, and the slide bar 18 will pass through the bottom of the copper-aluminum foil soft row group and drag the copper-aluminum foil soft row group. Through this process, the slide bar 18 can drag and grasp the bottom of both ends of the copper-aluminum foil soft row group, preparing for the subsequent clamping operation. The second cylinder 21 is then started to drive the chuck 19 to press down, and the chuck 19 cooperates with the slide bar 18 to clamp the copper-aluminum foil soft row group. Since the material picking device 16 is symmetrically arranged, it can clamp both ends of the copper-aluminum foil soft row group at the same time. This clamping method can ensure that the copper-aluminum foil soft row group does not slide or fall during transportation, thereby ensuring stability when entering the pre-welding device 4. When the copper-aluminum foil soft row group is clamped, the feeding device 7 can start working. The mobile frame 15 moves the clamped copper-aluminum foil flexible row group from the top of the unloading table 5 to the pre-welding device 4 through a three-axis moving device. The design of the feeding device 7 greatly improves the automation level of the production line. The manual intervention required by the operator during the entire process is significantly reduced, and the safety and stability of the production line are also improved. The entire feeding process not only improves production efficiency, but also provides a guarantee for the smooth progress of the subsequent welding process.

[0050] The unloading table 5 of the present invention is fixedly installed with a first separator comb 22 to improve the processing efficiency of the copper-aluminum foil soft row during the production process. The first separator comb 22 is used to separate the position of each copper-aluminum foil soft row on the unloading table 5 to ensure that confusion can be prevented when multiple copper-aluminum foil strips are processed at the same time. During the production process of the copper-aluminum foil soft row, the cutting device 6 cuts multiple copper-aluminum foil strips into specified lengths at the same time and stacks them on the unloading table 5 to form a stack of multiple copper-aluminum foil strips. By installing the first separator comb 22 on the unloading table 5, multiple copper-aluminum foil strips are separated to ensure that each copper-aluminum foil strip is arranged neatly and stacked in an orderly manner.

[0051] The clamping device 11 of the present invention is fixedly installed with a third cylinder 23, and the third cylinder 23 is connected to a pressure rod 24 by driving, and the pressure rod 24 is located above the receiving platform 8. The pre-welding device 4 is symmetrically arranged and can process both ends of the copper-aluminum foil soft row group at the same time. The main function of the receiving platform 8 is to place the copper-aluminum foil soft row group delivered by the feeding device 7 to prepare for subsequent welding operations. The two ends of the copper-aluminum foil soft row group are respectively placed on the corresponding receiving platform 8 to maintain stability and precision during the welding process. In the operation process, the working principle of the clamping device 11 is: before placing the copper-aluminum foil soft row group on the receiving platform 8, the third cylinder 23 is first started to move the pressure rod 24 away to provide enough space for the feeding device 7 so that it can smoothly place the copper-aluminum foil soft row group on the receiving platform 8. After completing the placement work, the third cylinder 23 is immediately started to move the pressure rod 24 back to its original position so that the pressure rod 24 is re-located above the receiving platform 8. At this time, the clamping device 11 is started, driving the pressure rod 24 to apply pressure downward to clamp the copper-aluminum foil flexible row group. In this way, the pressure rod 24 can firmly fix the copper-aluminum foil flexible row group on the receiving platform 8 to prevent it from any displacement or instability during the subsequent welding process.

[0052] A second material separation comb 25 is fixedly installed on the top of the material receiving platform 8 of the present invention. The setting of the second material separation comb 25 is similar to that of the first material separation comb 22, and is mainly used to separate multiple copper-aluminum foil flexible strips to ensure that each copper-aluminum foil flexible strip can be neatly arranged during the entire production process, reduce the intersection and confusion between materials, and enable the operation of each copper-aluminum foil flexible strip to be carried out without affecting other materials, thereby improving work efficiency and accuracy. The vibration device 9 is located on the side of the material receiving platform 8, and is mainly responsible for leveling the two ends of the copper-aluminum foil flexible strip group by vibrating and beating, in preparation for subsequent welding and fixing. Under the operation of the vibration device 9, the vibration will generate a certain frequency, and the two ends of the copper-aluminum foil flexible strip group will be quickly aligned through a uniform beating force.

[0053] The welding device 10 of the present invention adopts a laser welding method. This welding method has high efficiency and high quality, and is suitable for the welding requirements of copper-aluminum foil soft row materials. The welding device 10 is arranged beside the material receiving platform 8 to facilitate the welding of the copper-aluminum foil soft row placed on the material receiving platform 8. Laser welding technology uses a high-energy laser beam to quickly heat the welding material so that it melts and combines in a very short time. During the welding process, the laser beam is accurately aligned with the material to be welded, and the focused laser can penetrate into the surface of the material to form a molten pool, thereby achieving an effective connection between different materials. This is particularly important for the welding of copper-aluminum foil soft rows, because high-quality welding will directly affect the conductivity and service life of the product. The relative position setting of the welding device 10 and the material receiving platform 8 enables the laser welding operation to be carried out quickly. Before welding the copper-aluminum foil soft row, the operator can monitor and adjust the welding process in real time through the automatic control system. This setting not only improves the welding efficiency, but also greatly reduces the interference of human operation. In laser welding, the welding device 10 can greatly reduce the auxiliary materials required for welding. Compared with traditional welding processes, laser welding does not require the addition of welding wire or solder, which further reduces costs. When welding copper-aluminum foil flexible busbars, the solder-free feature of laser welding ensures the cleanliness of the welding area and the neatness of the board surface, and enhances the density and strength of the weld. In this way, the reliability and durability of the produced copper-aluminum foil flexible busbars in subsequent use are also improved.

[0054] The auxiliary material device 12 of the present invention includes a support plate 26, a gate knife 27 and an auxiliary material feeding device 28. The auxiliary material device 12 is mainly used to provide nickel sheets and auxiliary copper and aluminum foil sheets. The support plate 26 is provided with a nickel sheet discharge trough 29 and a copper and aluminum foil discharge trough 30 for placing the required auxiliary materials to provide necessary support for the welding process. The support plate 26 is fixedly installed with a fourth cylinder 31, and the fourth cylinder 31 drives the connection gate knife 27 to cut off the auxiliary materials when necessary. In the production process, the welding of the copper and aluminum foil soft row requires nickel sheets to be placed at both ends to improve the wear resistance and oxidation resistance of the copper and aluminum foil soft row. At the same time, the increase of the auxiliary copper and aluminum foil sheets helps to improve the welding effect of the copper and aluminum foil soft row in the polymer diffusion welding stage. By increasing the extrusion force during welding, the firmness of the welding is significantly enhanced, thereby ensuring the quality and reliability of the final product. When stacking materials, the auxiliary material feeding device 28 is responsible for conveying the nickel sheet and the auxiliary copper and aluminum foil sheets to the nickel sheet discharge trough 29 and the copper and aluminum foil discharge trough 30 respectively. When the nickel sheet and the auxiliary copper and aluminum foil are ready, the fourth cylinder 31 will start, and rely on its power to cut the nickel sheet and the auxiliary copper and aluminum foil, which is convenient for subsequent picking and placing operations. The auxiliary material picking and placing device 32 is installed above the receiving platform 8 and the support plate 26, and can operate the nickel sheet and the auxiliary copper and aluminum foil in the nickel sheet discharge trough 29 and the copper and aluminum foil discharge trough 30. According to production requirements, the auxiliary material picking and placing device 32 takes out the required auxiliary materials and places them on the receiving platform 8.

[0055] A material buffer device 33 is provided between the strip cutting device 1 and the feeding device 2 of the present invention, and the main function of the device is to buffer the copper and aluminum foil strips between the strip cutting device 1 and the feeding device 2. In the actual production process, there is a difference in the feeding and discharging rhythm of the strip cutting device 1 and the feeding device 2. In general, the discharging speed of the strip cutting device 1 remains relatively uniform, while the feeding speed of the feeding device 2 is sometimes fast and sometimes stopped. In order to avoid the copper and aluminum foil strips being torn off due to inconsistent speeds, a material buffer device 33 is provided. The material buffer device 33 effectively solves the problem caused by the mismatch of the operating rhythms between the two devices. When the copper and aluminum foil strips cut by the strip cutting device 1 enter the feeding device 2 through the buffer device, the material buffer device 33 acts as a temporary storage area to facilitate the adjustment of the speed difference between the two. When the strip cutting device 1 sends out the copper and aluminum foil strips, even if the feeding device 2 stops working at a certain moment, the material buffer device 33 can still maintain the continuity of the copper and aluminum foil strips, avoiding the breakage caused by the forced pulling of the material. With the coordination of the material buffer device 33, the operation of the entire production line is more stable, which promotes the improvement of production efficiency. It can not only reduce the failure rate caused by the uncoordinated operation of the equipment, but also reduce the waste caused by material damage. Through the reasonable configuration between the slitting device 1 and the unloading device 2, the material buffer device 33 ensures that the production operation can proceed smoothly in a stable working environment.
