Abstract
Description
Technical Field
[0001] This invention relates to the field of embedded parts production equipment technology, specifically to a multi-station automated production line for embedded parts in nuclear power plants. Background Technology
[0002] Embedded components are steel structural members that are pre-embedded in concrete in civil engineering projects. Commonly used embedded components for nuclear power plants consist of anchor plates, anchor bars, and anchor blocks. The anchor bars and anchor blocks are combined to form anchor claws. Embedded components play a key role in the installation of steel structures in the construction of nuclear power plants.
[0003] The existing manufacturing technology for embedded parts in nuclear power plants has significant limitations: it involves manual assembly, welding, grinding, and handling. When faced with heavy steel plates and reinforcing bars, manual production is inefficient, has a high error rate, high production costs, high labor intensity, and a slow production cycle. In addition, the manufacturing process for embedded parts in nuclear power plants involves hot work such as welding and post-weld grinding, which poses a high safety hazard. Summary of the Invention
[0004] To address the technical problems associated with the manual production of embedded parts for nuclear power plants, this invention provides a multi-station automated production line for embedded parts in nuclear power plants. This line can automatically process embedded parts for nuclear power plants, thereby improving the production efficiency of embedded parts, reducing labor intensity, and avoiding the safety hazards associated with manual operation.

[0060] In summary, the multi-station automated production line for nuclear power plant embedded parts provided in this embodiment includes a raw material storage workstation 600, a rust removal workstation 100, a machining workstation 200, an anchor claw welding workstation 300, a processing buffer workstation, an assembly welding workstation 400, a grinding workstation 500, a workstation awaiting inspection and repair 700, and a material cart.
[0061] During processing, raw materials are placed into the material frame manually or using a vibratory feeding assembly. The material frame is then scanned to register the raw material information and bind the raw material to the material frame. Anchor bars are transported to the sorting and rust removal workstation 100 by a material cart as needed. The material cart delivers the material frame to this area, where the first multi-axis robotic arm 130 picks up the anchor bars and places them into the laser rust removal worktable 120. The anchor bars are then rust-removed using laser cleaning. After rust removal, the first multi-axis robotic arm 130 picks up the anchor bars and places them into the material frame, which is then transported by the material cart to the buffer area or directly to the next process.
[0062] Meanwhile, the material cart delivers anchor plates and anchor blocks to the machining workstation 200 according to demand. Machining of the anchor plates and anchor blocks is completed in this area, including drilling and beveling. Specifically, for anchor plate machining: after the material cart delivers the raw material to the working area of the anchor plate machining mechanism 210, 3D vision is used for image positioning. The second multi-axis robotic arm 214 picks up the anchor plate and places it into a CNC machine tool (machining center or special-purpose machine tool). The CNC machine tool is used to machine the raw material. After completion, the second multi-axis robotic arm 214 picks up the anchor plate and places it into a material frame, which is then transported by the material cart to the buffer area or directly to the next process. For anchor block machining: after the material cart delivers the raw material to the working area of the anchor block machining mechanism 220, the third multi-axis robotic arm 224 picks up the anchor block and places it into a CNC machine tool. The CNC machine tool is used to machine the raw material. After completion, the third multi-axis robotic arm 224 picks up the anchor block and places it into a material frame, which is then transported by the material cart to the buffer area or directly to the next process.
[0063] Then, the material cart delivers the anchor bar material frame and the anchor block material frame to the anchor claw welding workstation 300 to complete the work of welding the anchor bar and the anchor block into the anchor claw: the material cart delivers the material frame into this area, the first welding robot 330 grabs the anchor bar and puts it into the anchor claw welding workstation 300, and after the welding is completed, the first welding robot 330 grabs the anchor bar and puts it into the material frame, which is then sent to the post-weld cooling area by the material cart.
[0064] In addition, the material cart delivers the polished anchor claw material frame and anchor plate material frame to the assembly welding workstation 400 to complete the assembly welding work; the material cart delivers the material frame into this area, and the anchor plate is photographed and positioned by 3D vision. The second welding robot grabs the anchor plate and anchor claw and puts them into the assembly welding workstation 400. After welding is completed, the second welding robot grabs the assembly and puts it into the material frame, which is then sent to the post-weld cooling area by the material cart.
[0065] For the grinding of the anchor claw: The material cart sends the anchor claw material frame from the post-weld cooling area to the grinding workstation 500. The robot grabs the anchor claw and puts it into the grinding station for grinding. After grinding, the robot (multi-axis robotic arm) grabs the anchor claw and puts it into the material frame. The anchor claw is then sent to the assembly welding workstation 400 via the material cart.
[0066] For the grinding of embedded parts assemblies: The material cart delivers the assembly frame from the post-weld cooling area to the grinding workstation 500. The 3D vision system takes pictures and positions the assembly to be ground. The robot (multi-axis robotic arm) picks up the embedded parts assembly and places it into the grinding station. After grinding, the robot picks up the assembly and places it into the frame. The assembly is then sent to the inspection and rework area via the material cart.
[0067] After the material cart transports the polished assembly to the inspection and repair workstation 700, the assembly is manually hoisted and stacked, awaiting inspection and repair.
[0068] In summary, the multi-station automated production line for nuclear power plant embedded parts provided in this embodiment can automatically process nuclear power plant embedded parts, thereby improving the production efficiency of nuclear power plant embedded parts, reducing labor intensity, and avoiding safety hazards associated with manual operation.
