Weld positioning accuracy depends on manual operation and is easily affected by workpiece assembly errors, resulting in unstable welding quality. There is a lack of effective process monitoring and arc light protection, which poses safety hazards and makes it difficult to trace welding quality. Loading and unloading use non-automated methods such as forklifts, which cannot achieve continuous production line operation and restrict the improvement of production cycle.

[0027] Furthermore, such as Figure 2 and Figure 7As shown, a limiting component 13 is provided on the pallet 102.

[0029] During implementation, by setting up workstation 1, powered roller conveyor line 12, limit component 13, welding robot group 17, wire drawing robot group 18, laser vision sensor 114 and monitoring camera, the manual transfer and operation time can be reduced, production efficiency can be greatly improved, flexible manufacturing of "small batch and multiple varieties" can be realized, equipment investment costs can be reduced, the stable operation of the electrical control system and cooling system can ensure system continuity, the full-process monitoring and parameter recording function can facilitate welding quality traceability and system optimization, and reduce the defect rate.

[0030] This invention also provides a robotic intelligent welding and wire drawing process for multi-specification capacitor boxes, applied to the aforementioned system, comprising the following steps: S1. Pre-treatment of incoming workpieces: Ensure that the workpieces are cut neatly and without burrs, the misalignment during assembly is ≤0.3mm, and the surface is free of impurities such as oxidized grease; S2, Powered Roller Conveyor: The workpiece is loaded onto a pallet and enters the workstation. The light-blocking curtain is automatically retracted, and the rollers drive the pallet to the welding platform. S3. Flexible positioning and laser positioning: The pneumatic clamping device positions the workpiece, and the laser real-time tracking system scans the weld seam and outputs positioning data. S4. Lowering the blackout curtain and starting welding: The welding platform is raised and lowered to the appropriate height, the blackout curtain is closed, and the welding robot performs TIG welding according to the positioning data. S5. Wire drawing robot linkage grinding: After welding is completed, the wire drawing robot is started, and the intelligent floating grinding head grinds the weld seam with constant force; S6. Finished product output: After grinding, the light-blocking curtain is automatically retracted, and the powered roller transports the workpiece to the next station. S7. Process monitoring and data recording: The monitoring system records welding / wire drawing parameters throughout the entire process, forming a quality traceability archive.

[0031] Working principle: When in use, first place the workstation 1 in the designated location. After the system is started, the PLC controller 11 controls the power roller conveyor 12 to send the pallet 102 carrying the workpiece body 101 into the workstation 1. At this time, the automatic light-shielding curtain 14 automatically rises. When the pallet 102 reaches directly above the platform 19, the PLC controller 11 sends a signal, and the pneumatic lifting mechanism rises to lift the pallet 102. Subsequently, the right clamp group 112 and the left clamp group 113 move to firmly fix the workpiece body 101. After fixing, the automatic light-shielding curtain 14 descends and closes, the welding robot group 17 starts, the laser vision sensor 114 scans the weld seam and extracts trajectory data, and the welding robot arm 172 guides the welding torch 173 to perform TIG welding according to the data. After welding is completed, the welding robot arm 172 returns to the zero point.

[0032] Subsequently, the wire drawing robot group 18 is started, and the wire drawing robotic arm 182 drives the intelligent floating grinding head 183 to contact the weld. The force sensor inside the intelligent floating grinding head 183 feeds back the grinding force to the PLC controller 11 in real time, maintaining constant force grinding to remove welding slag and spatter, making the surface smooth. After grinding is completed, the wire drawing robotic arm 182 is reset, the automatic light-blocking curtain 14 on the other side of the workstation 1 is raised, the right clamp group 112 and the left clamp group 113 are released, the pneumatic lifting mechanism on the powered roller conveyor line 12 is lowered, and the tray 102 falls back onto the roller of the powered roller conveyor line 12.

[0033] Subsequently, the power roller conveyor 12 starts and sends the workpiece body 101, which has completed welding and wire drawing, out of the workstation 1, completing one work cycle. Throughout the process, the monitoring camera inside the workstation 1 records the video in real time and stores it in the memory card of the PLC controller 11 for subsequent quality traceability.

[0034] This embodiment solves all the problems mentioned in the background art through the above structure and system, and realizes high-precision, high-efficiency and intelligent welding and wire drawing linkage production of multi-specification capacitor boxes.

[0035] The system employs a welding robot group 17 and a laser vision sensor 114 to achieve precise and controllable welding results. The cooperation between the welding robot group 17 and the wire drawing robot group 18 reduces manual transfer and operation time, significantly improving production efficiency. It also enables flexible compatibility of the right-side fixture group 112 and the left-side fixture group 113 with multiple specifications of workpiece bodies 101, expanding product design possibilities and realizing flexible manufacturing of "small batches and multiple varieties," thereby reducing equipment investment costs. The workstation 1 isolates arc light and welding slag, and the safety interlock mechanism prevents misoperation. The stable operation of the electrical control system and cooling system ensures system continuity. The full-process monitoring and parameter recording functions facilitate welding quality traceability and system optimization, reducing the defect rate.

[0036] Based on robot intelligent control technology, this system integrates functional modules such as real-time laser tracking, force-controlled floating wire drawing, flexible conveying, and intelligent protection to achieve fully automated linkage operation from workpiece conveying, positioning, welding, wire drawing to finished product output. Specifically, it includes the following key links: In view of the differences in workpiece body 101 with different specifications and plate thicknesses, right-side fixture group 112 and left-side fixture group 113 are designed to achieve multi-specification compatibility through rapid changeover.

[0037] Welding robot group 17 employs TIG welding and uses a Fanuc robot. Its control cabinet receives weld seam positioning data from the laser tracking system, adjusts the welding posture, and achieves precise weld seam filling, ensuring a beautiful weld seam shape, smooth transition, and absence of defects such as slag, undercut, and porosity. After welding is completed, the wire drawing robotic arm 182 automatically starts, equipped with an intelligent floating grinding head 183, which integrates force sensors, displacement sensors, and tilt sensors to sense the grinding force, floating position, and grinding head posture in real time. A constant grinding force is maintained through the PLC controller 11, performing fine grinding on the weld seam area. ， Remove spatter and weld beads to ensure the flatness of the surface of the workpiece body 101.

[0038] The welding process of welding robot group 17 and the wire drawing process of wire drawing robot group 18 are synchronized through PLC controller 11. After welding robot arm 172 completes welding, wire drawing robot arm 182 simultaneously follows up with grinding, without manual intervention, which shortens the process interval of intelligent welding and wire drawing system and improves processing efficiency.

[0039] The conveying method adopted by the powered roller conveyor 12 is that the workpiece body 101 is carried on the pallet 102 and is transferred by the roller. In conjunction with the pneumatic lifting mechanism, the workpiece body 101 is smoothly transferred and lifted and positioned. During the conveying process, it is linked with the automatic light-blocking curtain 14. When the workpiece body 101 arrives, the PLC controller 11 controls the automatic light-blocking curtain 14 to automatically retract. After the conveying is completed, the automatic light-blocking curtain 14 descends to block the arc light and ensure the safety of operation.

[0040] Two monitoring cameras are installed diagonally at the workstation to collect real-time images of the welding and wire drawing process, record robot operating parameters, weld formation status and grinding effect, which facilitates quality traceability and fault diagnosis.

[0041] Specifically: The workpiece body 101 to be processed is placed on the tray 102. Under the action of the limiting clamp 134, the placement position of the workpiece body 101 is limited. Then, the moving clamp 133 moves to contact the other side of the workpiece body 101. Under the combined action of the moving clamp 133 and the limiting clamp 134, the workpiece body 101 is limited and fixed on the tray 102, ensuring that the workpiece body 101 is neatly unloaded, burr-free, and free of impurities such as oxidized grease on the surface.

[0042] The powered roller conveyor 12 carries the pallet 102, which is equipped with the workpiece body 101, into the workstation 1. The automatic light-blocking curtain 14 is automatically retracted, and the rollers on the powered roller conveyor 12 drive the pallet 102 to the welding platform in the workstation 1.

[0043] Subsequently, the right clamping group 112 and the left clamping group 113 clamp and position the workpiece body 101. The laser vision sensor 114 tracks the weld of the workpiece body 101 in real time and outputs positioning data to the PLC controller 11. The automatic light-blocking curtain 14 closes, the welding robot group 17 performs TIG welding according to the positioning data, and the wire drawing robot group 18 performs grinding in conjunction. After the welding is completed, the wire drawing robot arm 182 starts, and the intelligent floating grinding head 183 performs constant force grinding on the weld of the workpiece body 101.

[0044] After grinding is completed, the automatic light-blocking curtain 14 on the other side of the workstation 1 automatically retracts, and the power rollers of the power roller conveyor line 12 transport the workpiece body 101 to the next station. The monitoring camera inside the workstation 1 records the welding parameters of the welding robot group 17 and the wire drawing parameters of the wire drawing robot group 18 throughout the process, forming a quality traceability file.

[0045] The system enables seamless switching between workpieces 101 of various sizes via right-side fixture group 112 and left-side fixture group 113. The welding robot group 17 and wire drawing robot group 18 are linked and controlled. Based on the timing coordination algorithm of PLC controller 11, the welding and wire drawing processes are seamlessly connected, improving production efficiency. The laser vision sensor 114 ensures consistent grinding, increasing product qualification rate. The system integrates conveying, positioning, welding, grinding, monitoring, and protection functions to achieve unmanned operation. Multi-level protection design reduces safety risks. The PLC controller 11 uses a Siemens main control system and multi-protocol communication, supporting real-time equipment status monitoring and parameter traceability, providing data support for intelligent production. Compared to traditional manual welding and wire drawing methods, this system reduces manual operation time by approximately 70%, shortens changeover time to less than 5 minutes, and increases the first-pass yield to over 98%. The goal is to achieve efficient processing of the welding wire drawing system, thereby reducing manual handling and operation time, significantly improving production efficiency, enabling flexible manufacturing of "small batches and multiple varieties," reducing equipment investment costs, ensuring system continuity through stable operation of the electrical control and cooling systems, and facilitating welding quality traceability and system optimization by providing full-process monitoring and parameter recording functions, thereby reducing the defect rate and ultimately completing the application of the robotic intelligent welding wire drawing system.
