Description

Technical Field

[0001] This application relates to the field of flow battery manufacturing technology, and in particular to an integrated welding and riveting device for flow battery electrode shells. Background Technology

[0002] As a large-scale energy storage device, a flow battery stack consists of hundreds of repeating single-cell units connected in series. The core components of each single-cell unit typically include electrode plates, bipolar plates, sealing gaskets, and a housing. Among these, the reliable connection and sealing between the electrode plates and the housing are crucial to ensuring the long-term leak-free operation and stable performance of the battery stack.

[0003] Currently, the assembly and manufacturing of flow battery electrode shells generally employs step-by-step, discrete processing methods, especially welding and riveting, which are inefficient. Therefore, this application proposes an integrated welding and riveting equipment for flow battery electrode shells to solve this technical problem. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide an integrated welding and riveting device for the electrode shell of a flow battery, which solves the technical problems mentioned in the background art.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a flow battery electrode shell welding and riveting integrated equipment, including a frame, a carrier, and a transport frame set on the frame for placing the carrier. The upper end of the transport frame is provided with welding equipment, the lower end of the transport frame is provided with riveting equipment, the carrier is provided with a temporary fixing component for pressing, and the frame is also provided with an opening and closing component for opening and closing the temporary fixing component.

[0006] By adopting the above technical solution, this application creatively integrates the two independent processes of welding and riveting, which originally had to be performed step-by-step at different workstations, into a vertically arranged continuous processing unit by setting the welding equipment and riveting equipment at the upper and lower ends of the transport frame, respectively, and cooperating with a carrier capable of carrying the workpiece and an automatically opening and closing temporary fixing component. This integrated design allows the electrode housing assembly to undergo welding above and riveting below sequentially or simultaneously with the transport frame after being clamped and positioned once on the carrier, without the need for intermediate disassembly, handling, and realignment. This completely eliminates the waiting time and repeated positioning errors in process connection in traditional discrete processing methods, which not only directly and significantly improves assembly efficiency and shortens the production cycle, but also significantly improves the positional accuracy and process consistency of welding and riveting by ensuring the consistency of the reference throughout the critical connection and sealing processes, thus improving production efficiency and fundamentally enhancing the reliability of the battery housing connection. Furthermore, the fixing assembly includes a rotating clamping mounting plate fixedly connected to the carrier, a clamping guide shaft rotatably inserted into the rotating clamping mounting plate, a clamping rotating plate rotatably disposed at the upper end of the clamping guide shaft, a pressing pin fixedly disposed on the clamping rotating plate, a spring sleeved on the upper end of the clamping guide shaft, the upper end of the spring fixedly connected to the upper end of the clamping guide shaft, and pressing positioning posts fixedly connected to both ends of the rotating clamping mounting plate, with grooves formed on the pressing positioning posts.

[0007] By adopting the above technical solution, this component, through the synergistic action of the rotating clamping mounting plate, the clamping guide shaft, the clamping rotating plate with the press-fit pin, and the spring and the grooved press-fit positioning pin, constitutes a temporary fixing mechanism integrating precise positioning, elastic clamping, and avoidance functions. Its specific effects are as follows: First, the press-fit positioning pin and its groove can reliably provide initial positioning and constraint for the workpiece, such as the electrode shell; second, the pressure applied by the spring to the clamping guide shaft, through the clamping rotating plate and the press-fit pin, flexibly and firmly presses the workpiece into the predetermined position on the carrier, preventing displacement during subsequent transportation and welding processes, thus ensuring welding accuracy.

[0008] Furthermore, the fixing assembly also includes a rotating mounting base plate fixedly connected to the carrier. A bearing support seat is fixedly connected to the upper end of the rotating mounting base plate. A rotating shaft is rotatably mounted on the bearing support seat. A rotating plate is fixedly connected to the rotating shaft. A tension spring mounting plate is fixedly connected to the upper end of the rotating plate. A tension spring is fixedly mounted between the tension spring mounting plate and the bearing support seat. A pressure head fixing strip is fixedly connected to the end of the rotating plate. A swing plate is fixedly connected to the pressure head fixing strip.

[0009] By adopting the above technical solution, the cooperation between the tension spring mounting plate and the tension spring provides a continuous and stable elastic clamping force for the entire rotating plate and the end pressure head fixing strip and swing plate. Specifically, when the opening and closing assembly acts on the appropriate position of the rotating plate, the rotating plate will rotate around the rotation axis, thereby driving the end swing plate to lift, realizing the release or avoidance of the workpiece; when the opening and closing assembly removes the force, under the action of the tension spring's restoring force, the rotating plate will automatically reset, driving the swing plate to swing downward and clamp the workpiece. This design cleverly transforms the linear or rotational movement of the opening and closing assembly into a vertical clamping or releasing movement of the workpiece, achieving controllable movement and automatic reset of the clamping force of the fixing assembly. It also ensures that sufficient and uniform clamping force is applied to the workpiece during processing to prevent displacement.

[0010] Furthermore, the opening and closing assembly includes a bottom film fixing frame fixedly connected to the frame, an opening and closing cylinder fixedly connected to the bottom film fixing frame, a rotating gripper mounting plate fixedly connected to the output end of the opening and closing cylinder, a rotating motor fixedly connected to the rotating gripper mounting plate, and a pneumatic gripper fixedly connected to the bottom of the output end of the rotating motor. The pneumatic gripper is used to clamp and hold the rotating plate.

[0011] By adopting the above technical solution, firstly, the workpiece is placed on the carrier and initially positioned by the positioning pin; then, the opening and closing assembly is activated, and its pneumatic gripper, driven by a cylinder and motor, precisely clamps and manipulates the clamping rotating plate and swing plate mechanism in the fixing assembly, so that the riveting pin and the swing plate, under the action of springs and tension springs, elastically and firmly press the workpiece. Next, the carrier carries the fixed workpiece continuously through the processing station: when the upper welding equipment completes welding, the workpiece remains stationary, ensuring weld accuracy; when the workpiece moves to the lower riveting station, the upward force of the riveting equipment directly acts on the riveting pin, causing it to automatically compress and lift, making way for precise riveting operation; after completion, the pin automatically resets under the action of the spring. Finally, the opening and closing assembly operates again to release the fixation, and the workpiece can be removed, and the carrier cycles back to the starting point.

[0012] Furthermore, the opening and closing assembly also includes an opening and closing cylinder mounting plate fixedly connected to the frame. A slide cylinder is fixedly connected to the opening and closing cylinder mounting plate, and the output end of the slide cylinder is fixedly connected to the slide mounting plate. A swing cylinder is also fixedly connected to the slide mounting plate, and the output end of the swing cylinder is fixedly connected to the swing mounting plate. A swing motor is fixedly mounted on the swing mounting plate, and the output end of the swing motor is fixedly connected to a swing rod mounting plate. A swing rod is fixedly connected to the swing rod mounting plate, and the swing rod is used to agitate the swing plate.

[0013] By adopting the above technical solution, this application achieves the following: First, the slide cylinder extends linearly, delivering the entire module, which integrates the swing cylinder, swing motor, and swing rod, to the operating position near the swing plate. Then, the swing cylinder drives the swing mounting plate and the swing motor to swing to a preset large angle. Subsequently, the swing motor rotates precisely, driving the swing rod mounting plate and the swing rod to rotate precisely to the optimal angle to embed into the force-bearing part of the swing plate. Afterward, the swing motor rotates according to the command, directly agitating the swing plate through the swing rod, thereby driving the pressure head fixing strip and the rotating plate fixed thereto to rotate around the rotation axis. When it is necessary to clamp the workpiece, the swing rod pushes the swing plate downward, causing the clamping element at the end of the pressure head fixing strip to press against the workpiece. The tension spring is stretched and stores energy, providing holding force after clamping. When it is necessary to release, the swing rod reverses and agitates upward, lifting the swing plate and overcoming the tension spring force to lift the clamping element. After the action is completed, the swing rod rotates and moves away, and the slide cylinder retracts, resetting the entire module.

[0014] Furthermore, the welding equipment includes a support welding frame fixedly connected to the frame, a linear track fixedly connected to the support welding frame, a welding sliding plate slidably mounted on the linear track, a linear motor fixedly connected to the linear track, a lead screw rotatably mounted on the linear track, the welding sliding plate and the lead screw being threadedly connected, a welding lifting plate fixedly connected to the upper end of the welding sliding plate, welding cylinder assemblies at both ends of the welding sliding plate, and an ultrasonic welding head at the bottom of each welding cylinder assembly.

[0015] By adopting the above technical solution, the output end of the linear motor is fixedly connected to the lead screw, thus forming a drive system that can precisely control the stable and rapid longitudinal movement of the welding sliding plate along a linear track, which determines the main feed direction of welding. The welding lifting plate and welding cylinder assembly provide precise vertical movement, allowing the ultrasonic welding head to not only be raised or lowered as a whole according to the workpiece height, but also to achieve independent fine-tuning and clamping or conformal movement during welding via the cylinder, ensuring uniform welding pressure. The welding cylinder assembly at both ends allows for parallel welding with two welding heads simultaneously, or alternating operation to cover longer weld seams, greatly improving welding efficiency. The entire system is integrated on a rigid support welding frame, ensuring the stability and repeatability of the welding process. This design enables the welding equipment to flexibly and accurately complete high-quality, high-efficiency sealing welding between the electrode shell and the component, and is a key functional module ensuring the automated and integrated operation of the welding process.

[0016] Furthermore, the welding cylinder assembly includes a first welding cylinder fixedly connected to the welding lifting plate, a second welding cylinder fixedly connected to the output end of the first welding cylinder, and the ultrasonic welding head fixedly connected to the output end of the second welding cylinder.

[0017] By adopting the above technical solution, the first welding cylinder, as the main lifting drive mechanism, is responsible for realizing the large-scale, rapid vertical movement of the ultrasonic welding head. It is mainly used to quickly adjust the welding head height during non-welding stages (such as avoidance or repositioning), or to quickly lower the welding head to a position close to the workpiece before welding begins. This significantly shortens idle time and improves equipment cycle time. Subsequently, the second welding cylinder, as the precision pressure and pressure holding mechanism, performs small-stroke, precisely pressure-controlled fine-tuning movements based on the positioning of the first cylinder. At the moment of welding, the second cylinder outputs a set pressure, driving the ultrasonic welding head to closely adhere to the workpiece surface and maintaining this pressure constant throughout the entire welding cycle. This ensures that ultrasonic energy is uniformly and stably transmitted to the welding interface, which is crucial for forming a consistent and reliable sealed weld.

[0018] Furthermore, the riveting equipment includes a guide rail pad fixedly connected to the bottom of the frame. A riveting module base is slidably mounted on the upper end of the guide rail pad. A guide rail motor is fixedly mounted on one side of the guide rail pad. A guide rail lead screw is fixedly mounted on the output end of the guide rail motor. The guide rail lead screw is threadedly connected to the riveting module base. A riveting slide plate is slidably mounted on the riveting module base. A linkage motor is fixedly connected to the base. A linkage lead screw is fixedly connected to the output end of the linkage motor. The linkage lead screw is threadedly connected to the riveting slide plate. A punch mounting plate is fixedly connected to the upper end of the riveting slide plate. A punch fixing block is fixedly connected to the punch mounting plate. A rivet is mounted on the upper end of the punch fixing block.

[0019] By adopting the above technical solution, this application includes a CCD camera. The CCD camera first scans the positioned workpiece on the carrier, accurately identifies the actual coordinates of each riveting hole, and compares them with the preset theoretical coordinates to calculate the comprehensive position compensation in the X-axis and Y-axis (or Z-axis) directions. Subsequently, through the cooperation of the guide rail motor and the guide rail screw, the entire riveting module base frame is driven to perform a wide-range and precise position adjustment in the horizontal direction (X-axis) to match the lateral distribution of riveting points on workpieces of different specifications. Then, through the cooperation of the linkage motor and the linkage screw, the riveting slide plate and the punch mounting plate and punch fixing block above it are driven to perform precise micro-movements in another direction (Y-axis or Z-axis, depending on the installation direction, usually in a plane perpendicular to the guide rail), achieving the final precise positioning of a single riveting point. This design allows a single riveting punch to efficiently and accurately cover multiple preset riveting positions on the workpiece, eliminating the need for an independent punch for each riveting point, greatly improving the applicability and economy of the equipment.

[0020] In summary, this application offers the following beneficial technical effects: By integrating welding and riveting into a continuous flow carrier system, and combining it with intelligent fixing components featuring self-locking and clearance functions, as well as multi-degree-of-freedom opening and closing components, a fundamental shift from discrete step-by-step processing to integrated continuous production is achieved, significantly shortening the production cycle and substantially improving assembly efficiency. Welding and riveting are completed in a single workpiece clamping, ensuring consistent process standards. Combined with constant pressure control during welding and visual guidance positioning during riveting, connection accuracy, sealing reliability, and quality consistency are greatly improved, fundamentally guaranteeing the long lifespan and leak-proof performance of the battery casing. Simultaneously, the modular and highly flexible design allows the equipment to adapt to various workpiece specifications, reducing the need for specialized tooling and improving equipment utilization and economy. Overall, this equipment simultaneously achieves multiple goals of high efficiency, high precision, high automation, and high reliability, representing an innovative solution to the bottleneck of large-scale manufacturing of flow battery electrode casings.

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] Example, refer to Figures 1-5A flow battery electrode shell welding and riveting integrated device includes a frame (not shown in the figure), a carrier 11, and a transport frame 1 mounted on the frame for placing the carrier 11. A welding device is mounted on the upper end of the transport frame 1, and a riveting device is mounted on the lower end. A temporary fixing component is mounted on the carrier 11, and an opening and closing component is mounted on the frame for opening and closing the temporary fixing component. This application creatively integrates the welding and riveting processes, which originally had to be performed separately at different workstations, into a vertically arranged continuous processing unit by placing the welding and riveting devices at the upper and lower ends of the transport frame 1, respectively, and combining them with the workpiece-carrying carrier 11 and the automatically opening and closing temporary fixing component. This integrated design allows the electrode housing assembly to undergo welding above and riveting below sequentially or simultaneously with the transport frame 1 after being clamped and positioned once on the carrier 11. This eliminates the need for intermediate disassembly, handling, and realignment, thus completely eliminating the waiting time and repetitive positioning errors in process connections in traditional discrete processing methods. This not only directly and significantly improves assembly efficiency and shortens production cycle time, but also significantly improves the positional accuracy and process consistency of welding and riveting by ensuring the consistency of the reference throughout the critical connection and sealing processes. This also improves production efficiency and fundamentally enhances the reliability of battery housing connections.

[0025] The fixing assembly includes a rotary clamping mounting plate 2 fixedly connected to the carrier 11. A clamping guide shaft 21 is rotatably inserted into the rotary clamping mounting plate 2. A clamping rotary plate 22 is rotatably mounted on the upper end of the clamping guide shaft 21. A pressing pin 24 is fixedly mounted on the clamping rotary plate 22. A spring 23 is sleeved on the upper end of the clamping guide shaft 21. The upper end of the spring 23 is fixedly connected to the upper end of the clamping guide shaft 21. Pressing positioning pins 25 are fixedly connected to both ends of the rotary clamping mounting plate 2. Grooves are provided on the pressing positioning pins 25.

[0026] This component, through the coordinated action of the rotating clamping mounting plate 2, the clamping guide shaft 21, the clamping rotating plate 22 with the press-fit pin 24, the spring 23, and the grooved pressing positioning post 25, constitutes a temporary fixing mechanism integrating precise positioning, elastic clamping, and avoidance functions. Its specific effects are as follows: First, the pressing positioning post 25 and its groove can reliably provide initial positioning and constraint for the workpiece, such as the electrode shell; second, the pressure applied by the spring 23 to the clamping guide shaft 21, through the clamping rotating plate 22 and the press-fit pin 24, flexibly and steadily presses the workpiece into the predetermined position on the carrier 11, preventing displacement during subsequent transportation and welding, thus ensuring welding accuracy.

[0027] The fixing assembly also includes a rotating mounting base plate 26 fixedly connected to the carrier 11. A bearing support seat 27 is fixedly connected to the upper end of the rotating mounting base plate 26. A rotating shaft 28 is rotatably mounted on the bearing support seat 27. A rotating plate 29 is fixedly connected to the rotating shaft 28. A tension spring mounting plate is fixedly connected to the upper end of the rotating plate 29. A tension spring 291 is fixedly mounted between the tension spring mounting plate and the bearing support seat 27. A pressure head fixing strip 292 is fixedly connected to the end of the rotating plate 29. A swing plate 293 is fixedly connected to the pressure head fixing strip 292.

[0028] The engagement of the mounting plate with the tension spring 291 provides a continuous and stable elastic clamping force for the entire rotating plate 29, the end pressure head fixing strip 292, and the swing plate 293. Specifically, when the opening and closing assembly is applied to the appropriate position of the rotating plate 29, the rotating plate 29 rotates around the rotation axis 28, thereby lifting the end swing plate 293 to release or avoid the workpiece. When the opening and closing assembly removes the force, the rotating plate 29 automatically returns to its original position under the restoring force of the tension spring 291, causing the swing plate 293 to swing downward and clamp the workpiece. This design cleverly transforms the linear or rotational motion of the opening and closing assembly into a vertical clamping or releasing motion on the workpiece, achieving controllable movement and automatic reset of the clamping force of the fixing assembly. It also ensures sufficient and uniform clamping force is applied to the workpiece during processing to prevent displacement.

[0029] The opening and closing assembly includes a bottom film fixing frame 3 fixedly connected to the frame, an opening and closing cylinder 31 fixedly connected to the bottom film fixing frame 3, a rotating gripper mounting plate 32 fixedly connected to the output end of the opening and closing cylinder 31, a rotating motor 33 fixedly connected to the rotating gripper mounting plate 32, and a pneumatic gripper 34 fixedly connected to the bottom of the output end of the rotating motor 33. The pneumatic gripper 34 is used to clamp and hold the rotating plate 22.

[0030] First, the workpiece is placed on the carrier 11 and initially positioned by the positioning pin. Then, the opening / closing assembly is activated, and its pneumatic gripper 34, driven by a cylinder and motor, precisely clamps and manipulates the clamping rotating plate 22 and swing plate 293 mechanism in the fixing assembly. This causes the riveting pin 24 and swing plate 293 to elastically and firmly press the workpiece under the action of spring 23 and tension spring 291. Next, the carrier 11 carries the fixed workpiece continuously through the processing station: the workpiece remains stationary while the upper welding equipment completes welding, ensuring weld accuracy; when the workpiece moves to the lower riveting station, the upward force of the riveting equipment directly acts on the riveting pin 24, causing it to automatically compress and lift, making way for precise riveting operations. After completion, the pin automatically resets under the action of spring 23. Finally, the opening / closing assembly activates again to release the fixation, and the workpiece can be removed. The carrier 11 then cycles back to the starting point.

[0031] The opening and closing assembly also includes an opening and closing cylinder 31 mounting plate fixedly connected to the frame. A slide cylinder 4 is fixedly connected to the opening and closing cylinder 31 mounting plate. A slide mounting plate 41 is fixedly connected to the output end of the slide cylinder 4. A swing cylinder is also fixedly connected to the slide mounting plate 41. A swing mounting plate 42 is fixedly connected to the output end of the swing cylinder. A swing motor 43 is fixedly installed on the swing mounting plate 42. A swing rod mounting plate 44 is fixedly connected to the output end of the swing motor 43. A swing rod 45 is fixedly connected to the swing rod mounting plate 44. The swing rod 45 is used to agitate the swing plate 293.

[0032] In this application, the sliding cylinder 4 first extends linearly, delivering the entire module, which integrates the swing cylinder, swing motor 43, and swing rod 45, to the operating position near the swing plate 293. Then, the swing cylinder drives the swing mounting plate 42 and the swing motor 43 to swing to a preset large angle. Subsequently, the swing motor 43 rotates precisely, driving the swing rod mounting plate 44 and the swing rod 45 to rotate precisely to the optimal angle to engage with the force-bearing part of the swing plate 293. Afterward, the swing motor 43 rotates according to the command, directly agitating the swing plate 293 via the swing rod 45. The movable plate 293 drives the pressure head fixing strip 292 and the rotating plate 29 fixed thereto to rotate around the rotating shaft 28. When it is necessary to press the workpiece, the swing rod 45 pushes the swing plate 293 to swing down, so that the pressing element at the end of the pressure head fixing strip 292 presses against the workpiece. The tension spring 291 is stretched and stores energy and provides holding force after pressing. When it is necessary to release, the swing rod 45 stirs in the opposite direction and lifts the swing plate 293, overcoming the tension of the tension spring 291 and lifting the pressing element. After the action is completed, the swing rod 45 rotates and moves away, and the slide cylinder 4 retracts and the entire module resets.

[0033] The welding equipment includes a support welding frame 5 fixedly connected to the frame, a linear rail 51 fixedly connected to the support welding frame 5, a welding sliding plate 52 slidably mounted on the linear rail 51, a linear motor 53 fixedly connected to the linear rail 51, a lead screw rotatably mounted on the linear rail 51, the welding sliding plate 52 and the lead screw being threadedly connected, a welding lifting plate 54 fixedly connected to the upper end of the welding sliding plate 52, welding cylinder assemblies at both ends of the welding sliding plate 52, and an ultrasonic welding head 57 at the bottom of each welding cylinder assembly.

[0034] The drive system, consisting of linear motor 53 and lead screw, precisely controls the stable and rapid longitudinal movement of welding sliding plate 52 along linear track 51, thus determining the main feed direction for welding. Welding lifting plate 54 and welding cylinder assembly provide precise vertical movement, allowing ultrasonic welding head 57 to not only rise or fall as a whole according to workpiece height, but also achieve independent fine-tuning and clamping or conformal movement during welding via cylinders, ensuring uniform welding pressure. The welding cylinder assembly at both ends allows for parallel welding with two welding heads simultaneously, or alternating operation to cover longer weld seams, significantly improving welding efficiency. The entire system is integrated onto a rigid support welding frame 5, ensuring stability and repeatability in the welding process. This design enables the welding equipment to flexibly and precisely complete high-quality, high-efficiency sealing welding between the electrode shell and the component, making it a key functional module for ensuring automated and integrated operation of the welding process.

[0035] The welding cylinder assembly includes a first welding cylinder 55 fixedly connected to the welding lifting plate 54, a second welding cylinder 56 fixedly connected to the output end of the first welding cylinder 55, and an ultrasonic welding head 57 fixedly connected to the output end of the second welding cylinder 56.

[0036] The first welding cylinder 55, acting as the main lifting drive mechanism, is responsible for enabling the ultrasonic welding head 57 to move rapidly and with a large range in the vertical direction. It is primarily used to quickly adjust the welding head height during non-welding phases (such as avoidance or repositioning), or to quickly lower the welding head to a position close to the workpiece before welding begins. This significantly shortens idle time and improves the equipment cycle time. Subsequently, the second welding cylinder 56, acting as a pressure-pressuring and pressure-holding mechanism, performs small-stroke, precisely pressure-controlled fine-tuning movements based on the positioning of the first cylinder. At the moment of welding, the second cylinder outputs a set pressure, driving the ultrasonic welding head 57 to tightly adhere to the workpiece surface and maintaining this pressure constant throughout the entire welding cycle. This ensures that ultrasonic energy is transmitted evenly and stably to the welding interface, which is crucial for forming a consistent and reliable sealed weld.

[0037] The riveting equipment includes a guide rail pad 6 fixedly connected to the bottom of the frame. A riveting module base 61 is slidably mounted on the upper end of the guide rail pad 6. A guide rail motor 62 is fixedly mounted on one side of the guide rail pad 6. A guide rail screw 63 is fixedly mounted on the output end of the guide rail motor 62. The guide rail screw 63 is threadedly connected to the riveting module base 61. A riveting slide plate 64 is slidably mounted on the riveting module base 61. A linkage motor 65 is fixedly connected to the riveting module base 61. A linkage screw 66 is fixedly connected to the output end of the linkage motor 65. The linkage screw 66 is threadedly connected to the riveting slide plate 64. A punch mounting plate is fixedly connected to the upper end of the riveting slide plate 64. A punch fixing block 67 is fixedly connected to the punch mounting plate. A rivet is mounted on the upper end of the punch fixing block 67.

[0038] This application incorporates a CCD camera. The CCD camera first scans the positioned workpiece on the carrier 11, accurately identifying the actual coordinates of each riveting hole and comparing them with preset theoretical coordinates to calculate the comprehensive position compensation in the X and Y (or Z) axes. Then, through the cooperation of the guide rail motor 62 and the guide rail lead screw 63, the entire riveting module base 61 is driven to perform a wide-range, precise position adjustment in the horizontal direction (X-axis) to match the lateral distribution of riveting points on workpieces of different specifications. Subsequently, through the cooperation of the linkage motor 65 and the linkage lead screw 66, the riveting slide plate 64 and the punch mounting plate and punch fixing block 67 above it are driven to perform precise micro-movements in another direction (Y-axis or Z-axis, depending on the installation direction, usually in a plane perpendicular to the guide rail), achieving final precise positioning of a single riveting point. This design allows a single riveting punch to efficiently and accurately cover multiple preset riveting positions on the workpiece, eliminating the need for an independent punch for each riveting point, greatly improving the applicability and economy of the equipment.

[0039] The specific implementation process is as follows: The workpiece is first placed on the carrier 11 and initially positioned by the clamping and positioning column 25. Then, the opening and closing assembly is activated, and its pneumatic gripper 34 module precisely clamps and presses down the rotating plate 22. At the same time, the swing rod 45 module agitates the swing plate 293, so that the riveting pin 24 and the swing plate 293, under the synergistic action of the spring 23 and the tension spring 291, elastically and firmly press the workpiece onto the carrier 11. The carrier 11 then carries the fixed workpiece and moves continuously along the transport frame 1. When passing the upper welding station, the ultrasonic welding head 57, driven by the linear motor 53 and controlled by the two-stage cylinder, performs high-quality sealing welding on the workpiece. After the welding is completed, the carrier 11 moves to the lower riveting station without stopping. At this time, under the visual guidance of the CCD industrial camera, the riveting equipment positions the rivet to the precise coordinates after visual compensation through dual-axis precision drive. At the same time, the moving force of the riveting punch lifts the riveting pin 24 to achieve automatic repositioning and complete the riveting. Finally, the opening and closing assembly moves again to release all clamping, the workpiece is removed, and the empty carrier 11 returns to the loading position, forming a fully automatic and uninterrupted processing cycle.

[0040] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
