Description

Technical Field

[0001] This utility model relates to the field of welding equipment, specifically to an ultrasonic welding device for coarse aluminum wire in automotive power batteries. Background Technology

[0002] As the core component of electric vehicles, the automotive power battery is a storage battery that provides power to the vehicle. Its main function is to store electrical energy and convert it into mechanical energy during vehicle operation, thereby driving the vehicle's motor and enabling the vehicle to move. Unlike traditional fuel vehicle engines that generate power by burning gasoline or diesel, electric vehicles rely on the electricity output from the power battery for propulsion. It is one of the key technologies for achieving zero or low emissions in automobiles and plays a pivotal role in promoting the development of new energy vehicles.

[0003] In the production process of automotive power batteries, welding equipment is generally used to weld aluminum wires onto the chips for assembly. Currently, the most common welding method for automotive power battery electrodes is resistance welding. This method utilizes the resistance heat generated by the current passing through the contact points of the workpieces to locally heat the workpieces to a plastic or molten state, forming a weld joint under pressure. The two electrodes press the workpiece together, creating contact resistance between the two metal layers under electrode pressure. When the welding current flows from one electrode to the other, instantaneous heat is generated at the contact resistance point to achieve welding. This method has the advantages of low production cost and simple operation.

[0004] However, the welding methods commonly used in the market have certain drawbacks. They are usually done manually by taking the welding equipment, which makes it impossible to accurately control the welding parameters, ensure the welding quality, and reduce the efficiency of the welding work. Therefore, we propose an ultrasonic coarse aluminum wire welding device for automotive power batteries. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an ultrasonic coarse aluminum wire welding device for automotive power batteries, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic coarse aluminum wire welding device for automotive power batteries, comprising an operating table, a mounting frame fixedly installed on the top of the operating table, and a housing fixedly installed on the outer wall of the mounting frame, the housing being composed of profiles and an acrylic protective cover, a dual-drive servo module provided on the top of the operating table, a gantry frame slidably installed on the top of the dual-drive servo module, a servo module provided on the top of the gantry frame, a welding component slidably installed on the outer wall of the servo module, and a lifting component fixedly connected to the top of the operating table inside the mounting frame;

A lead screw is provided at the end of the transmission assembly, and a lifting plate is rotatably mounted at the end of the lead screw. A support plate is fixedly mounted on the top of the lifting plate.

[0008] By adopting the above technical solutions, welding operations are carried out inside the mounting frame and housing, effectively protecting internal components and ensuring a safe welding environment. The gantry, dual-drive servo module, and servo module work together with the support plate, welding components, lifting components, drive motor, transmission components, lead screw, and lifting plate to enable automated operation of the welding mechanism. This allows for precise control of welding parameters, stable energy transfer during welding, and consistent welding results. It also reduces deviations that may occur during manual operation, ensures welding quality, and significantly improves welding efficiency. Furthermore, ultrasonic welding produces no sparks or heat, reducing the consumption of welding materials and minimizing environmental pollution.

[0009] Furthermore, two sets of the dual-drive servo modules are symmetrically arranged on the top of the control panel, and the dual-drive servo modules are located inside the mounting bracket.

[0010] By adopting the above technical solution, the movement of the gantry can be realized through the dual-drive servo module.

[0011] Furthermore, the servo module and the dual-drive servo module are arranged perpendicularly, and the length of the servo module corresponds to the spacing between the two sets of dual-drive servo modules.

[0012] By adopting the above technical solution, the welding components can move within the servo module, enabling automated and flexible welding.

[0013] Furthermore, the lifting assembly is located between two sets of dual-drive servo modules.

[0014] By adopting the above technical solution, the workpiece to be welded is located within the moving range of the welding assembly, which facilitates the welding operation of the welding assembly.

[0015] Furthermore, the lifting plate is symmetrically arranged at the bottom of the support plate, and the lifting plate is perpendicular to the support plate.

[0016] By adopting the above technical solution, the support plate is subjected to uniform force during jacking, ensuring welding accuracy.

[0017] Furthermore, two sets of lead screws are symmetrically arranged at the bottom of the lifting plate, and the length of the lead screws corresponds to the lifting range of the lifting assembly, and the transmission assembly is arranged correspondingly to the lead screws.

[0018] By adopting the above technical solution, the support plate can be raised and lowered by rotating the lead screw, so that the workpiece to be welded can be sent to the welding assembly for welding.

[0019] In summary, the present invention has the following main advantages:

[0020] This invention features a mounting frame and a housing, allowing welding operations to be performed inside these components. This effectively protects internal parts and ensures a safe welding environment. By incorporating a gantry frame, a dual-drive servo module, and a servo module that works in conjunction with a support plate, welding components, lifting components, a drive motor, a transmission component, a lead screw, and a lifting plate, the welding mechanism achieves automated operation. It allows for precise control of welding parameters, stable energy transfer during welding, and consistent welding results. This reduces potential deviations during manual operation, ensures welding quality, and significantly improves welding efficiency. Furthermore, ultrasonic welding produces no sparks or heat, reducing material consumption and environmental pollution. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] An ultrasonic welding device for automotive power batteries, such as Figure 1 - Figure 6 As shown, the system includes an operating table 1, a mounting frame 2 fixedly installed on the top of the operating table 1, and a housing 3 fixedly installed on the outer wall of the mounting frame 2. The housing 3 is composed of profiles and an acrylic protective cover, so that the welding operation is carried out inside the mounting frame 2 and the housing 3, effectively protecting the internal components and ensuring the safety of the welding environment. A dual-drive servo module 41 is provided on the top of the operating table 1, and a gantry 4 is slidably installed on the top of the dual-drive servo module 41. A servo module 5 is provided on the top of the gantry 4, and a welding component 7 is slidably installed on the outer wall of the servo module 5. A lifting component 8 is fixedly connected to the top of the operating table 1 inside the mounting frame 2.

[0031] The lifting assembly 8 includes a drive motor 81 mounted on the top of the operating table 1, and a transmission assembly 82 is provided at the output end of the drive motor 81. A lead screw 83 is provided at the end of the transmission assembly 82, and a lifting plate 84 is rotatably mounted at the end of the lead screw 83. A support plate 6 is fixedly mounted on the top of the lifting plate 84. This allows the gantry 4, the dual-drive servo module 41, and the servo module 5 to cooperate with the support plate 6, the welding assembly 7, the lifting assembly 8, the drive motor 81, the transmission assembly 82, the lead screw 83, and the lifting plate 84. This enables the welding mechanism to achieve automated operation, accurately control welding parameters, ensure stable energy transfer during welding, achieve stable welding results, reduce deviations that may occur during manual operation, ensure welding quality, and significantly improve welding efficiency. Furthermore, ultrasonic welding produces no sparks or heat, reducing the consumption of welding materials and lowering environmental pollution.

[0032] Please see Figures 2-4 Two sets of dual-drive servo modules 41 are symmetrically arranged on the top of the control panel 1, and the dual-drive servo modules 41 are located inside the mounting frame 2, so that the gantry 4 can be moved through the dual-drive servo modules.

[0033] Please see Figures 2-4 The servo module 5 and the dual-drive servo module 41 are arranged vertically, and the length of the servo module 5 is set in accordance with the distance between the two sets of dual-drive servo modules 41, so that the welding assembly 7 can move in the servo module to realize automated and flexible welding.

[0034] Please see Figures 2-6 The lifting component 8 is located between the two sets of dual-drive servo modules 41, so that the workpiece to be welded is within the moving range of the welding component 7, which facilitates the welding operation of the welding component 7.

[0035] Please see Figures 2-6 The lifting plate 84 is symmetrically arranged at the bottom of the support plate 6, and the lifting plate 84 is perpendicular to the support plate 6, so that the support plate 6 is subjected to uniform force during lifting and the welding accuracy is ensured.

[0036] Please see Figures 2-6 Two sets of lead screws 83 are symmetrically arranged at the bottom of the lifting plate 84, and the length of the lead screws 83 corresponds to the lifting range of the lifting assembly 8. The transmission assembly 82 is also arranged in relation to the lead screws 83, so that the lifting and lowering of the support plate 6 is achieved by rotating and raising the lead screws 83, and the workpiece to be welded is sent to the welding assembly 7 for welding.

[0037] The working principle of this utility model is as follows: When performing welding, the workpiece to be welded is first placed above the support plate 6. Then, the dual-drive servo module 41 is started, which drives the gantry 4 to move. When the gantry 4 moves to the position of the workpiece to be welded, it stops moving. At this time, the welding component 7 on the top of the gantry 4 begins to move to the position of the workpiece to be welded on the outer wall of the servo module 5. Then, the drive motor 81 of the lifting component 8 is started. The drive motor 81 drives multiple sets of lead screws 83 to rotate through the transmission component 82. Since the lead screws 83 have threads distributed on their outer walls, they lift upwards while rotating, thereby driving the lifting plate 84 and the support plate 6 to lift. The workpiece to be welded is lifted to the welding component 7 for welding. Under the action of pressure and vibration, the welding component 7 rubs against the surface of the workpiece to be welded through ultrasonic waves. The oxide film is destroyed and plastic deformation occurs, causing the two pure metal surfaces to come into close contact, achieving atomic-distance bonding, and finally forming a strong metal bond, thus realizing welding.
