Abstract
Description
Technical Field
[0001] This application relates to the technical field of ultrasonic welding, specifically to a copper-aluminum bar lifting and demolding structure. Background Technology
[0002] In the field of ultrasonic copper-aluminum busbar welding, the conventional welding method is generally aluminum on top and copper on the bottom. This welding method is superior for aluminum busbars with a thickness of ≤3mm. However, as the thickness of the aluminum busbar increases, the advantage of this welding method diminishes. Due to the low thermal conductivity of aluminum, it takes longer for the heat generated by the ultrasonic vibration of the aluminum busbar to be conducted to the copper busbar below, and the interface temperature fails to reach the welding requirements for a long time. Aluminum has low hardness, and when it comes into direct contact with the welding head during welding, it is affected by ultrasonic vibration and heat, causing the aluminum busbar to soften, deform, and stick to the welding head, resulting in difficulty in demolding and the risk of damaging the core components.
[0003] Against this backdrop, a welding method with copper on top and aluminum on the bottom was adopted for thick aluminum strips. However, there is a risk that the aluminum strips will stick to the bottom mold during the welding process, which will make it difficult to remove the welded workpiece. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0031] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0032] This application provides a copper-aluminum strip lifting and demolding structure, referring to... Figures 1-3 The copper-aluminum strip lifting and demolding structure is mounted on the tooling plate 1 in the welding machine. It includes a power output component 2, a transmission rod 3, a fixing frame 4, and a lifting component 5. The power output component 2 and the fixing frame 4 are fixedly mounted on the tooling plate 1. One end of the transmission rod 3 is rotatably connected to the output end of the power output component 2. The lifting component 5 is bolted to the transmission rod 3 and is positioned below the workpiece. After welding, the power output component 2 drives the transmission rod 3 to rotate, and the connection point between the transmission rod 3 and the fixing frame 4 is the rotation center of the transmission rod 3. This causes the transmission rod 3 to drive the lifting component 5 to lift the welded workpiece, facilitating its removal.
[0033] Reference Figure 1 The power output component 2 can be a cylinder, hydraulic cylinder, etc. In other embodiments, a servo motor and transmission gear can also be used as the power output component 2, which will not be described in detail in this application.
[0034] Reference Figure 1 and 3 In this embodiment, the power output component 2 is described using a cylinder equipped with a speed regulating valve as an example. The cylinder body of the power output component 2 is fixedly connected to the tooling fixing plate 1 via the cylinder mounting plate 6. The telescopic rod of the power output component 2 is vertically arranged and a connecting block 7 is fixedly installed at its end. One end of the transmission rod 3 is rotatably connected to the connecting block 7, so that the transmission rod 3 can rotate in the vertical plane under the drive of the telescopic rod.
[0035] Since the ejector component 5 needs to be in direct contact with the workpiece, in order to reduce the possibility of damage to the workpiece, refer to Figure 1 and Figure 3 The top material component 5 is configured to include a pulley mounting block 51 and a top material wheel 52, and the top material wheel 52 may be a nylon wheel. The pulley mounting block 51 is fixedly connected to the end of the transmission rod 3 away from the power output component 2 by bolts, and the top material wheel 52 is rotatably connected to the pulley mounting block 51 and can rotate in a vertical plane.
[0036] To improve connection strength, the pulley mounting block 51 and the transmission rod 3 are respectively provided with a protrusion 81 and a groove 82 for accommodating the protrusion 81, and the protrusion 81 and the groove 82 are engaged in a snap-fit fit. (Refer to...) Figure 1 and Figure 2The protrusion 81 is fixedly connected to the side wall of the pulley mounting block 51 facing the transmission rod 3, and the groove 82 is formed on the side wall of the transmission rod 3.
[0037] Reference Figure 4 The end of the transmission rod 3 furthest from the power output component 2 is hinged to the fixed frame 4. The pulley mounting block 51 is located on the transmission rod 3 near the fixed frame 4. When the telescopic rod of the power output component 2 extends upward, it drives the end of the transmission rod 3 connected to the connecting block 7 to move upward. Under the constraint of the fixed frame 4, the transmission rod 3 and the pulley mounting block 51 rotate upward together about the hinge point on the fixed frame 4, thereby causing the top wheel 52 to lift the welded workpiece.
[0038] Reference Figure 5 In another embodiment, the transmission rod 3 can also be rotatably connected to the fixed frame 4, and the pulley mounting block 51 is located on the side of the fixed frame 4 away from the power output component 2. Considering the lever principle, the distance between the connection point of the transmission rod 3 and the fixed frame 4 and the pulley mounting block 51 is less than the distance to the output end of the power output component 2. When the telescopic rod of the power output component 2 retracts downward, it will drive the end of the transmission rod 3 connected to the connecting block 7 to move downward. Under the restriction of the fixed frame 4, the transmission rod 3 rotates about the hinge point on the fixed frame 4 as the axis, so that the top material wheel 52 located on the other side pushes the welded workpiece upward.
[0039] The copper-aluminum strip lifting and demolding structure provided in this application embodiment, by setting up a power output component 2, a transmission rod 3, a fixed frame 4 and a material ejector 5, after the welding operation is completed, the power output component 2 can drive the transmission rod 3 to rotate, thereby causing the transmission rod 3 to drive the material ejector 5 to lift the welded workpiece, which is convenient for the workpiece to be removed and improves production efficiency.
[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
