Technical Field

[0001] This utility model belongs to the field of intelligent welding technology, specifically relating to a novel centralized control system for intelligent welding. Background Technology

[0002] Industrial robots are the most representative equipment in intelligent manufacturing, and their large-scale application is an important means to replace human labor and improve production efficiency in the future manufacturing industry. Among them, welding robots are one of the most important categories of industrial robots. Traditional welding robots have been widely used in industries such as automotive and 3C, but they cannot meet the non-standard welding needs of processes such as steel structures and shipbuilding. Intelligent welding is needed to meet these flexible welding requirements.

[0003] Currently, existing intelligent welding systems mainly consist of a central control cabinet, an operating console, a robot body, a robot control cabinet, a welding power supply system, a weld seam sensor system, and welding fixtures. The central control cabinet, as the power and communication core of the welding system, provides power to the peripherals of the entire machine and communicates with the robot and weld seam sensors, and is mounted on the motion platform. The central control cabinet lacks scalability; the large number of devices housed in the same cabinet increases its size and complicates wiring, making it prone to interference and hindering signal transmission. Furthermore, the cables between the central control cabinet and external devices are redundant in length, resulting in complex wiring. Utility Model Content

The air-mounted connector and the gas connector can be quickly connected, making operation convenient and significantly reducing the amount of manual wiring. This improves the assembly efficiency of the centralized control system for intelligent welding and effectively solves the problems of redundant cable lengths and complicated wiring between the centralized control cabinet and external equipment in the prior art.

[0016] Furthermore, this utility model discloses that the power cabinet is also provided with a second device mounting plate inside the cabinet. The second device mounting plate can be expanded with several drivers for driving and controlling external axes.

[0023] Specifically, the power cabinet is connected to a global camera to acquire workpiece parameters (such as point cloud information and spatial position information of the workpiece relative to the robot's installation position), the power cabinet is connected to a weld seam sensor to acquire the weld seam position, and the power cabinet is connected to the robot control cabinet to control the robot's welding motion process.

[0024] The power cabinet serves as the power supply and control center, connecting the welding power source, oil pump, and fume purifier. It can control the on / off state of the welding power source, oil pump, and fume purifier according to actual needs.

[0025] The wire feeder and shielding gas are connected to the welding power source and are turned on according to the welding requirements during the welding process.

[0026] The power cabinet is mounted on the motion platform (also called the ground rail motion platform). As the core unit of the centralized control system (also called a new type of centralized control system for intelligent welding), the power cabinet contains a first component mounting plate. A schematic diagram of the first component mounting plate's arrangement is shown below. Figure 2 As shown, the first device mounting plate is provided with several one-in-many-out terminals (in this embodiment, the first device mounting plate is provided with four one-in-many-out terminals (used to split the main power supply into multiple AC power supplies), namely one-to-many-out terminal 1, one-to-many-out terminal 2, one-to-many-out terminal 3 and one-to-many-out terminal 4), a circuit breaker (used to control the power supply to external devices), a switch (used to realize data exchange between the power cabinet and external devices), a relay module and a safety relay. The first device mounting plate is also provided with multiple DC power supplies (DC power supply 1 and DC power supply 2) and DC power supply terminals.

The output terminal of the load switch is connected to the multi-terminal input terminal, thereby splitting the main power supply into multiple AC power supplies to power external equipment.

[0028] The multi-terminal output terminal connects to the robot control cabinet, welding power supply, fume purifier, DC power supply, cabinet fan of the operating table, and cabinet fan of the power cabinet.

[0029] The control panel is located outside the motion platform. Inside the cabinet of the control panel are an industrial control computer and a display screen, which are used to control the task execution of the new centralized control system for intelligent welding.

The design of the power cabinet with a front and rear door structure facilitates maintenance personnel to repair the components inside the power cabinet.

[0034] In this embodiment, both the first and second device mounting plates are metal plates. Metal plates have high strength and can withstand the weight of the device, thus preventing the device mounting plates from deforming or breaking.
