Description

Technical Field

[0001] The utility model relates to the technical field of sofa production, in particular to an iron frame assembly production line. Background Art

[0002] In the sofa manufacturing industry, the assembly of sofa iron frames is a key link in the production process, and its quality and efficiency directly affect the market competitiveness of the final product. At present, the common sofa iron frames on the market mainly include two categories: single-sided iron frames and floor-standing iron frames. These two types of iron frames have significant differences in structural design and assembly requirements.

[0003] As the name implies, a single-sided iron frame is designed with a support structure on one side and is more open or lightweight on the other side, which is suitable for sofa styles that require flexible configuration or space saving. During the assembly process, the single-sided iron frame usually needs to go through specific workstations for welding, assembly, and debugging to ensure its stability and durability.

[0004] In contrast, due to its more stable and stronger load-bearing capacity, the floor-standing iron frame is widely used in large sofas or occasions that require a higher load-bearing capacity. The assembly process of the floor-standing iron frame is relatively complex and involves more workstations and steps, such as welding of the bottom frame, installation of support legs, and debugging of the overall structure.

[0005] However, the existing sofa assembly production lines are often difficult to accommodate these two different types of iron frames in terms of design. Since the single-sided iron frame and the floor-standing iron frame need to pass through different workstations during the assembly process and have specific requirements for the layout and sequence between workstations, it is very difficult for traditional assembly lines to achieve compatible operation of the two. This has led to the need to set up multiple independent assembly lines on the production line to assemble different types of iron frames respectively, thus increasing production costs, occupying more production space, and reducing the overall production efficiency. Summary of the Utility Model

[0006] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides an iron frame assembly production line, which can solve the operation problems of multiple iron frames on the same production line, and reduce production costs and floor area.

[0007] The technical solution adopted by the utility model to solve its problems is:

[0008] An iron frame assembly production line, comprising: a conveying mechanism, the conveying mechanism including a starting end and an ending end, for mixing or interleaving and placing at least two types of iron frames and conveying them from the starting end to the ending end; a lifting and flipping station, the lifting and flipping station being located at the ending end of the conveying mechanism, for lifting and flipping the iron frames conveyed to this station; a support base, the support base being used for temporarily storing iron frames; a three-axis transportation mechanism, the three-axis transportation mechanism being used for transporting the iron frames lifted and flipped by the lifting and flipping station to the support base; an operating station, the operating station being used for operating the iron frames; a manipulator, the operating station and the support base being within the rotation radius of the manipulator, the manipulator being used for transporting the iron frames on the support base to the operating station, or transporting the iron frames on the operating station to the support base; wherein, the ratio of the number of iron frames, the number of support bases, the number of operating stations, and the number of manipulators is 1:1:1:1.

[0009] By adopting the above scheme, by designing a flexible conveying mechanism, a lifting and flipping station, and a three-axis transportation mechanism, it can meet the assembly requirements of different types of iron frames such as single-sided iron frames and floor-standing iron frames. These mechanisms can flexibly adjust their actions and paths according to the type and assembly requirements of the iron frames, so as to realize the compatible operation of multiple iron frames on the same production line; reduce the demand for production space, make the production layout more compact, and effectively save the floor area.

[0010] Further, the conveying mechanism includes a conveying frame, conveying rollers, a driving motor, and a transmission device for driving the conveying rollers to rotate. The iron frames slide on the conveying rollers, and an iron frame stopping mechanism is further provided on the conveying mechanism.

[0011] By adopting the above scheme, when the driving motor is started, the transmission device drives the conveying rollers to rotate. The iron frames are placed on the conveying rollers and slide forward as the rollers rotate, gradually moving from the starting end to the ending end of the conveying mechanism. The main function of the iron frame stopping mechanism is to quickly and accurately stop the iron frame when it reaches a predetermined position, so that more stoppages are convenient for temporary other inspections or installation operations, and also convenient for subsequent lifting and flipping operations.

[0012] Further, a plurality of iron frame stopping mechanisms are provided and linearly arranged along the conveying direction of the conveying mechanism, and the distance between every two iron frame stopping mechanisms is greater than the length of the iron frame in the conveying direction.

[0013] By adopting the above scheme, when it is necessary to pause or inspect the iron frames, any one of the stopping mechanisms can be activated; when it is necessary to process multiple iron frames simultaneously, it can ensure that there is enough distance between them to avoid mutual interference.

[0014] Furthermore, the three-axis transportation mechanism includes: a support frame; an X-axis rail, which is assembled at the top of the support frame; a Y-axis rail, which is slidable along the X-axis rail; a Z-axis telescopic iron frame clamp, which slides within the Y-axis rail; wherein, the end of the X-axis rail overlaps with a part of the projection of the end of the conveyor mechanism on the horizontal plane.

[0015] By adopting the above scheme, through the design of this three-axis transportation mechanism, the iron frame assembly line realizes the efficient and stable transportation of the iron frame from the conveyor mechanism to the support seat, providing strong support for subsequent assembly operations. At the same time, this mechanism also has high flexibility and adaptability, and can be adjusted and optimized according to different sizes and types of iron frames.

[0016] Furthermore, the support seat includes a first support seat and a second support seat, the manipulator includes a first manipulator and a second manipulator, the operation station includes a first operation station and a second operation station, and the first support seat, the second support seat, the first manipulator, the second manipulator, the first operation station and the second operation station are all within the movement range of the Z-axis telescopic iron frame clamp.

[0017] By adopting the above scheme, it not only improves the production efficiency and flexibility of the assembly line, but also ensures the stability and safety of the iron frame during the whole processing process.

[0018] Furthermore, the X-axis rail includes a first X-axis rail and a second X-axis rail. The first X-axis rail and the second X-axis rail are respectively used to support both ends of the Y-axis rail. The first X-axis rail is parallel to the conveyor mechanism. A conveyor platform parallel to the second X-axis rail is arranged below the second X-axis rail. The conveyor platform includes an overlapping area, and the overlapping area overlaps with the projection of the second X-axis rail on the horizontal plane.

[0019] By adopting the above scheme, the Z-axis telescopic iron frame clamp will descend within the overlapping area and release the iron frame onto the conveyor platform. The conveyor platform can continue to transport the iron frame to other parts of the assembly line for processing or assembly, improving the overall efficiency and flexibility of the assembly line, allowing multiple iron frames to be processed simultaneously without interrupting other operations, and being able to quickly and accurately transfer the iron frame between different workstations.

[0020] Furthermore, the iron frame includes a single-sided iron frame and a floor-standing iron frame. A footrest installation station is arranged in the overlapping area. The Z-axis telescopic iron frame clamp transports the single-sided iron frame in front of the footrest installation station in the overlapping area, and the Z-axis telescopic iron frame clamp transports the floor-standing iron frame behind the footrest installation station in the overlapping area.

[0021] By adopting the above solution, different iron racks can be conveyed by the Z-axis telescopic iron rack fixture, and the conveying position can be changed according to the type of iron rack, avoiding unnecessary operations on the iron rack. The system can minimize waiting time and resource waste, improve production efficiency, and ensure the overall efficiency and production capacity of the assembly line.

[0022] Furthermore, it also includes an electric control cabinet and a main control device. The electric control cabinet is used to supply power to the main control device, and the main control device is used to control the operation or stop of the assembly line.

[0023] By adopting the above solution, when the operator starts the assembly line, the main control device receives the start instruction, processes it, and then sends a control signal to the electric control cabinet. The electric control cabinet distributes power according to the control signal and starts the corresponding equipment or mechanism; the main control device continuously receives feedback signals from sensors, operators, or other external devices, and monitors the operating state of the assembly line in real time. Once an abnormality or failure is detected, the main control device will immediately take corresponding control measures, such as decelerating, stopping, or alarming, etc., to protect the safety of equipment and personnel, and can achieve the efficient, stable, and safe operation of the assembly line.

[0024] Furthermore, a laser positioning device is provided on the three-axis transportation mechanism and / or the robot arm.

[0025] By adopting the above solution, the laser positioning device emits a laser beam and receives the reflected signal, calculates the precise position information of the target object, and sends this information to the control system. The control system adjusts the movement trajectory and speed of the three-axis transportation mechanism or the robot arm according to the received position information to ensure that they can accurately reach the target position and execute tasks. During the execution of tasks, the laser positioning device will continuously monitor the position change of the target object and provide real-time feedback to the control system for necessary adjustment and optimization, greatly improving the operation accuracy of the assembly line.

[0026] Furthermore, the operation station is a screw-tightening station.

[0027] By adopting the above solution, screw-tightening operations can be performed on the iron construction.

[0028] In summary, an iron rack assembly line provided by the present utility model has the following technical effects:

[0029] 1. By setting up more than two operating stations and corresponding manipulators, simultaneous processing of double stations is achieved, significantly increasing the production volume of the production line. This means that more iron frame assembly work can be completed within the same time, thus improving the overall production efficiency. In a traditional single-station production line, after one station finishes processing, the next station needs to wait for the previous one to complete before it can start processing. However, this application eliminates this waiting time, and the two stations can process independently and simultaneously, greatly improving the operating efficiency of the production line.

[0030] 2. Since this assembly line can be compatible with various types of iron frames, such as single-sided iron frames and floor-standing iron frames, there is no longer a need to set up multiple independent assembly lines for different types of iron frames. This greatly reduces the investment cost and maintenance cost of the production line. Since the number of production lines is reduced and the layout is more compact, a large amount of production space can be saved, reducing the land and rental costs.

[0031] 3. The high-precision control of the three-axis transportation mechanism and the manipulator ensures the precise position of the iron frame during transfer and processing, thereby improving the processing accuracy and product quality. Through this application, it can be ensured that two iron frames are processed under the same conditions, which helps to maintain the consistency and high quality of the product.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this article are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0039] Refer to Figure 1 - Figure 2, the utility model discloses an iron frame assembly production line, including a conveying mechanism 1, a lifting and flipping station 2, a support seat 3, a three-axis transportation mechanism 4, a manipulator 6 and an operation station 5. The conveying mechanism 1 includes a starting end and an ending end, and is used for mixing or staggering at least two kinds of iron frames and conveying them from the starting end to the ending end. The conveying mechanism 1 adopts a roller path or chain conveying method, and can stably convey the iron frames from the starting end to the ending end. The lifting and flipping station 2 is closely arranged at the ending end of the conveying mechanism 1, and this station is equipped with a hydraulic or pneumatic device for lifting and flipping the iron frames conveyed here; the support seat 3 is used for temporarily storing iron frames; the three-axis transportation mechanism 4 is arranged above the conveying mechanism 1, and its X, Y, and Z axes can move independently or cooperatively to accurately transport the iron frames from the lifting and flipping station 2 to the designated support seat 3; an operation station 5 is respectively arranged beside two or more support seats 3. The operation station 5 is equipped with necessary processing equipment and tools for operations such as welding, assembling or debugging the iron frames. And both the operation station 5 and the support seat 3 are within the rotation radius of the manipulator 6. The manipulator 6 is used for transporting the iron frames on the support seat 3 to the operation station 5, or transporting the iron frames on the operation station 5 to the support seat 3; the ratio of the number of iron frames, the number of support seats 3, the number of operation stations 5 and the number of manipulators 6 is 1:1:1:1. By designing a flexible conveying mechanism 1, lifting and flipping station 2 and three-axis transportation mechanism 4, it can adapt to the assembly requirements of different types of iron frames such as single-sided iron frames and floor-standing iron frames. These mechanisms can flexibly adjust actions and paths according to the type and assembly requirements of the iron frames, so as to realize the compatible operation of multiple iron frames on the same production line; reduce the demand for production space, make the production layout more compact, and effectively save the floor area.

[0040] The double-station synchronous assembly method of this production line includes the following steps:

[0041] S1 Initialization: Before the production line starts, the lifting and flipping station 2, the manipulator 6 and the three-axis transportation mechanism 4 all automatically reset to the initialization state to ensure that each mechanism is in a standby state. Specifically, the lifting mechanism of the lifting and flipping station 2 is at the lowest position, the manipulator 6 rotates between the support seat 3 and the operation station 5, leaving space above both of them, and can also quickly reach above both of them. The three-axis transportation mechanism 4 is directly above the lifting mechanism of the lifting and flipping station 2;

[0042] S2 Iron frame conveying: Workers or other intelligent mechanisms mix different types of iron frames such as single-sided iron frames and floor-standing iron frames and place them at the starting end of the conveying mechanism 1. The conveying mechanism 1 starts to work and conveys the iron frames one by one to the ending end; [[ID=]10]

[0043] Transfer the iron frame to different workstations: When the iron frame reaches the end, the lifting and flipping station 2 starts to perform the lifting and flipping operations on the iron frame, so that it is in a posture convenient for the three-axis transportation mechanism 4 to grab. Subsequently, the three-axis transportation mechanism 4 transports the iron frame to the corresponding support base 3 according to the type of the iron frame and the preset program;

[0044] S4 Dual-station synchronous operation: The manipulators 6 of different support bases 3 respectively grab their iron frames to the operation station 5 for synchronous processing. The processed iron frames are transported back to the support base 3 by the manipulators 6 again. By using the dual stations for simultaneous processing, the production volume of the production line is significantly increased. At the two operation stations 5, different manipulators 6 can process two iron frames simultaneously, thus reducing the waiting time and improving the overall production efficiency; Optionally, at the operation station 5, necessary operations such as welding, assembly or debugging of the iron frame can be performed by workers or automated equipment, and after completion, the manipulator 6 sends the iron frame back to the support base 3; Preferably, the operation station 5 is a screw-tightening station.

[0045] S5 Subsequent transfer: For the iron frame processed at the operation station 5, if further processing or inspection is required, the three-axis transportation mechanism 4 will start again to grab the iron frame from the support base 3 and transport it to the subsequent workstation for processing.

[0046] In a specific embodiment, the conveying mechanism 1 includes a conveying frame 11, conveying rollers 12, a driving motor 13, and a transmission device 14 for driving the rotation of the conveying rollers 12. The iron rack slides on the conveying rollers 12. An iron rack stopping mechanism 15 is also provided on the conveying mechanism 1. The conveying frame 11 is the supporting structure of the entire conveying mechanism 1 and is made of a strong metal material such as stainless steel or aluminum alloy to ensure its stability and durability. The conveying frame 11 is designed with appropriate spacing and height to install the conveying rollers 12 and other necessary transmission components, while ensuring that the iron rack will not collide with or get stuck on the conveying frame 11 during the conveying process. A certain gap is maintained between the conveying rollers 12 to accommodate iron racks of different sizes and shapes, ensuring that the iron rack can slide smoothly on the rollers. Both ends of the conveying rollers 12 are installed on the conveying frame 11 through bearings and can rotate freely. The driving motor 13 is the power source of the conveying mechanism 1 and usually adopts a variable-frequency speed-regulating motor to achieve the adjustability of the conveying speed. The motor is connected to the conveying rollers 12 through the transmission device 14. When the motor starts, it drives the rotation of the conveying rollers 12 through the transmission device 14. The transmission device 14 includes but is not limited to a gearbox, a chain, or a pulley. The iron rack stopping mechanism 15 is an important auxiliary device on the conveying mechanism 1 and is used to quickly and accurately stop the iron rack when it reaches a predetermined position. This mechanism usually consists of components such as a cylinder, an electromagnet, and a mechanical stop, and can perform rapid actions according to control signals. When the iron rack is about to reach the stopping position, sensors such as photoelectric sensors and proximity switches can detect the presence of the iron rack and send signals to the control system. After receiving the signals, the control system immediately issues an instruction to the iron rack stopping mechanism 15 to make it act quickly and stop the iron rack at the predetermined position. The design of the iron rack stopping mechanism 15 should ensure that the stopping action is smooth and reliable and will not damage the iron rack. For this purpose, an elastic device such as sponge, rubber, or spring can be provided on the mechanical stop. When the driving motor 13 starts, it drives the rotation of the conveying rollers 12 through the transmission device 14. The iron rack is placed on the conveying rollers 12 and slides forward as the rollers rotate, gradually moving from the starting end to the ending end of the conveying mechanism 1. The main function of the iron rack stopping mechanism 15 is to quickly and accurately stop the iron rack when it reaches a predetermined position, and more stoppages are for facilitating temporary other inspections or installation operations, and can also facilitate subsequent lifting and flipping operations.

[0047] It should be noted that multiple iron rack stopping mechanisms 15 are provided and are linearly arranged along the conveying direction of the conveying mechanism 1. The spacing between every two iron rack stopping mechanisms 15 is greater than the length of the iron rack in the conveying direction. When it is necessary to pause or inspect the iron rack, any one of the stopping mechanisms can be activated; when it is necessary to process multiple iron racks simultaneously, it can ensure that there is sufficient spacing between them to avoid mutual interference.

[0048] In a specific embodiment, the three-axis transportation mechanism 4 includes a support frame 41, an X-axis track 42, a Y-axis track 43, and a Z-axis telescopic iron frame clamp 44. The X-axis track 42 is assembled at the top of the support frame 41. The support frame 41 is the main structure of the three-axis transportation mechanism 4 and is made of a sturdy metal material to ensure the stability and load-bearing capacity of the entire mechanism. The Y-axis track 43 can slide along the X-axis track 42, and the Z-axis telescopic iron frame clamp 44 slides within the Y-axis track 43. The clamp part of the Z-axis telescopic iron frame clamp 44 adopts a highly adaptable design and can firmly hold iron frames of different sizes and types to ensure that they will not loosen or fall off during transportation. The end of the X-axis track 42 partially overlaps with the projection on the horizontal plane of the end point of the conveyor mechanism 1. When the iron frame is conveyed to the end point by the conveyor mechanism 1, the control system will issue an instruction to start the three-axis transportation mechanism 4. First, the X-axis track 42 drives the Y-axis track 43 to slide to a position corresponding to the iron frame. Then, the Z-axis telescopic iron frame clamp 44 on the Y-axis track 43 descends to accurately align with and grasp the iron frame. Next, the Z-axis clamp ascends to lift the iron frame off the conveyor mechanism 1. Subsequently, the Y-axis track 43 and the X-axis track 42 work together to transport the iron frame above the designated support base 3. Finally, the Z-axis clamp descends again to place the iron frame steadily on the support base 3. During the whole process, the control system will monitor the position and state of the iron frame in real time to ensure the accuracy and safety of transportation. Through the design of this three-axis transportation mechanism 4, the iron frame assembly line realizes the efficient and stable transportation of the iron frame from the conveyor mechanism 1 to the support base 3, providing strong support for subsequent assembly operations. At the same time, this mechanism also has high flexibility and adaptability and can be adjusted and optimized according to iron frames of different sizes and types.

[0049] In the present Embodiment 1, the support base 3 includes a first support base 31 and a second support base 32, the manipulator 6 includes a first manipulator 61 and a second manipulator 62, the operation stations include a first operation station 51 and a second operation station 52. The first support base 31, the second support base 32, the first manipulator 61, the second manipulator 62, the first operation station 51, and the second operation station 52 are all within the movement range of the Z-axis telescopic iron frame fixture 44, which not only improves the production efficiency and flexibility of the production line but also ensures the stability and safety of the iron frame during the entire processing process. The X-axis track 42 includes a first X-axis track and a second X-axis track. The first X-axis track and the second X-axis track are respectively used to support both ends of the Y-axis track 43. The first X-axis track is parallel to the conveying mechanism 1. A conveying platform 7 parallel to the second X-axis track is provided below the second X-axis track. The conveying platform 7 includes an overlapping area 71. The overlapping area 71 overlaps with the projection of the second X-axis track on the horizontal plane. The Z-axis telescopic iron frame fixture 44 will descend within the overlapping area 71 and release the iron frame onto the conveying platform 7. The conveying platform 7 can continue to transport the iron frame to other parts of the production line for processing or assembly, improving the overall efficiency and flexibility of the production line, allowing multiple iron frames to be processed simultaneously without interrupting other operations, and enabling the rapid and accurate transfer of the iron frame between different stations.

[0050] In the present Embodiment 1, there are two types of iron frames, including single-sided iron frames and floor-standing iron frames. A footrest installation station 8 is provided in the overlapping area 71. The Z-axis telescopic iron frame fixture 44 conveys the single-sided iron frame to the front of the footrest installation station 8 in the overlapping area 71, and the Z-axis telescopic iron frame fixture 44 conveys the floor-standing iron frame to the rear of the footrest installation station 8 in the overlapping area 71. Different iron frames can be conveyed by the Z-axis telescopic iron frame fixture 44, and the conveying position changes according to the type of iron frame, avoiding unnecessary operations on the iron frame. The system can minimize waiting time and resource waste to the greatest extent, improve production efficiency, and ensure the overall efficiency and production capacity of the production line.

[0051] In one embodiment, the pipeline further includes an electric control cabinet 9 and a main control device 10. The electric control cabinet 9 serves as the core of the electrical control system, responsible for providing power, protecting the circuit, and transmitting control signals. The main control device 10 is used to control the operation or stop of the pipeline. When the operator starts the pipeline, the main control device 10 receives the start instruction, processes it, and sends a control signal to the electric control cabinet 9. The electric control cabinet 9 distributes power according to the control signal and starts the corresponding equipment or mechanism. The main control device 10 continuously receives feedback signals from sensors, operators, or other external devices, and monitors the operating state of the pipeline in real time. Once an abnormality or failure is detected, the main control device 10 will immediately take corresponding control measures, such as decelerating, stopping, or alarming, to protect the safety of the equipment and personnel, and can achieve the efficient, stable, and safe operation of the pipeline.

[0052] The double-station synchronous assembly method of this pipeline includes the following steps:

[0053] S1 Initialization: The main control device 10 issues an instruction, and the lifting and flipping station 2, the manipulator 6, and the three-axis transportation mechanism 4 are all reset to the initial state, waiting for the start of production;

[0054] S2 Iron frame transfer: Workers put different iron frames into the starting end of the transfer mechanism 1, and the transfer mechanism 1 starts to operate, transferring the iron frames from the starting end to the ending end;

[0055] S3 Transfer of iron frame to different stations: When the iron frame reaches the ending end of the transfer mechanism 1, the lifting and flipping station 2 starts to work, performing lifting and flipping operations on the iron frame. The lifted iron frame is within the grasping range of the three-axis transportation mechanism 4, and the three-axis transportation mechanism 4 transports it to the designated support seat 3 according to the type of the iron frame;

[0056] S4 Double-station synchronous operation: The manipulator 6 on the support seat 3 grasps the iron frame on it and transports it to the operation station 5 for processing. Since the ratio of the number of operation stations 5 to the number of manipulators 6 is 1:1, double-station synchronous processing can be achieved, improving production efficiency. After processing, the manipulator 6 transports the iron frame back to the support seat 3.

[0057] S5 Subsequent transfer: The three-axis transportation mechanism 4 works again, grasps the iron frame processed at the operation station 5 from the support seat 3, and transports it to subsequent stations; During the entire production process, the electric control cabinet 9 provides stable power and protection circuits to ensure the normal operation of the equipment. The main control device 10 performs real-time control according to the preset program and the signals feedback by the sensors to ensure the smooth operation of the pipeline.

[0058] In some embodiments, optionally, a laser positioning device is provided on the three-axis transportation mechanism 4 and / or the manipulator 6. The laser positioning device emits a laser beam and receives the reflected signal, calculates the precise position information of the target object, and sends this information to the control system. According to the received position information, the control system adjusts the movement trajectory and speed of the three-axis transportation mechanism 4 or the manipulator 6 to ensure that they can accurately reach the target position and perform tasks. During the task execution, the laser positioning device continuously monitors the position change of the target object and provides real-time feedback to the control system for necessary adjustment and optimization, greatly improving the operation accuracy of the assembly line.

[0059] In summary, a steel frame assembly line provided by the present utility model has the following technical effects:

[0060] 1. By providing more than two operation stations 5 and corresponding manipulators 6, simultaneous processing of double stations is achieved, significantly improving the production volume of the production line. This means that more steel frame assembly work can be completed within the same time, thus improving the overall production efficiency. In a traditional single-station production line, after one station finishes processing, the next station needs to wait for the previous station to complete before it can start processing. However, in this application, this waiting time is eliminated, and the two stations can process independently and simultaneously, greatly improving the operation efficiency of the production line.

[0061] 2. Since this assembly line can be compatible with various types of steel frames, such as single-sided steel frames and floor-standing steel frames, there is no longer a need to set up multiple independent assembly lines for different types of steel frames. This greatly reduces the investment cost and maintenance cost of the production line. Since the number of production lines is reduced and the layout is more compact, a large amount of production space can be saved, reducing the land and rental costs.

[0062] 3. The high-precision control of the three-axis transportation mechanism 4 and the manipulator 6 ensures the precise position of the steel frame during transportation and processing, thus improving the processing accuracy and product quality. Through this application, it can be ensured that two steel frames are processed under the same conditions, which helps to maintain the consistency and high quality of the products.

[0063] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present utility model.
