Description

Technical Field

[0001] This invention relates to the field of fully automated truss welding technology, and particularly to a fully automated truss welding production line. Background Technology

[0002] Trusses, as core load-bearing components of infrastructure such as conveyor corridors, industrial plant support frames, engineering machinery frames, and temporary bridge supports, have been widely used in heavy industry, building materials, and municipal engineering due to their advantages such as reasonable structural stress, high overall rigidity, and ease of on-site assembly. At present, trusses composed of multiple sets of welded channel steel are widely used in engineering projects. Channel steel profiles have good cross-sectional rigidity and are widely available. The upper chord, lower chord, and web members of the truss can all be directly processed from channel steel. The open structure of the channel steel also facilitates the installation and fixing of various auxiliary connectors and support plates. Compared with circular tube trusses and angle steel composite trusses, they have outstanding advantages in lateral torsion resistance and external accessory arrangement, thus becoming the mainstream manufacturing form of small and medium-sized load-bearing trusses. Against the backdrop of the rapid development of the intelligent manufacturing equipment industry, automated production line processing of steel structure components has become an important direction for the industry. The current conventional manufacturing process of channel steel trusses includes the following processing steps: feeding channel steel raw materials, cutting of members, assembly of members, punching of nodes, forming and welding. Under the existing production model, the processes of feeding, assembly, punching and welding are separated from each other, and each processing station is independent and equipped with separate processing equipment. The raw materials for channel steel are first conveyed and cut to a fixed length on the feeding equipment. Then, they are transported to the assembly station by crane or manually. Operators use simple tooling to align and spot weld multiple channel steels for pre-fixation. The pre-assembled semi-finished products are then transported to the punching equipment to punch connecting holes and mounting holes. After the punching process, the workpieces need to be transported to the welding station for full welding. In the entire processing flow, the workpieces need to be repeatedly transported between multiple independent stations. Material transfer channels and semi-finished product stacking areas need to be reserved between each station. The utilization rate of the factory space is low, which is not conducive to large-scale centralized production. The entire production process involves a large amount of manual operation, which is highly dependent on the skill level of the workers. The labor intensity is high, the process connection is poor, and it is impossible to form a continuous assembly line operation. The production cycle is difficult to control uniformly, and the overall processing efficiency is low. Therefore, a fully automatic truss welding production line is needed to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a fully automated truss welding production line to address the shortcomings of existing trusses constructed from welded channel steel. In this process, operators rely on simple tooling to align and pre-fix multiple channel steel sections using spot welding. The pre-assembled semi-finished products are then transferred to a punching machine to punch connecting and mounting holes. After the punching process, the workpieces need to be transferred to the welding station for full welding. Throughout this process, the workpieces need to be repeatedly transferred between multiple independent workstations. Material transfer channels and semi-finished product stacking areas need to be reserved between each workstation, resulting in low factory space utilization, hindering large-scale centralized production, and impacting production efficiency.

[0013] Preferably, two sets of the feeding platform and welding assembly are provided at the bottom end of the second gantry gripping assembly, and the two sets of the feeding platform and welding assembly are symmetrically distributed at the bottom end of the second gantry gripping assembly.

[0014] The fully automated truss welding production line provided by this invention has the following advantages: By incorporating a forward and reverse flipping structure, the mechanical flipping mechanism, composed of a feeding clamp, flipping shaft, gears, rack and pinion, and a moving cylinder, can automatically correct the orientation of the channel steel, eliminating the need for manual flipping, reducing labor intensity, avoiding manual placement deviations and channel steel collisions and deformations, unifying the processing posture of the channel steel, and providing a stable benchmark for punching operations of the punching components; the moving cylinder drives the gear and rack meshing transmission, ensuring stable and repeatable flipping action, precise control of the flipping angle, reducing alignment errors, and improving the punching position accuracy of the channel steel and consistency with products in the same batch; Furthermore, by setting up an alignment and flipping structure, a bidirectional flipping mechanism is formed by the first clamping claw, the second clamping claw, the first cylinder, the second cylinder, the first connecting frame, the second connecting frame, and the mounting plate. This mechanism can adjust the two sets of channel steel in opposite directions, accurately realize the relative arrangement of the support surfaces of the two sets of channel steel, eliminate the manual alignment process, and build a unified and reliable welding assembly benchmark.

[0015] Furthermore, the material feeding platform is equipped with an adsorption robot that automatically places small rectangular block shims. The shims are precisely positioned, and the gap between the two sets of channel steel is stably controlled, avoiding the problem of skewed placement of shims by manual placement and effectively improving the welding quality. The electromagnet adsorption clamp at the bottom of the second gantry gripping component can simultaneously grip the paired channel steel, preventing misalignment during single-piece transfer and improving the accuracy of channel steel assembly.

[0016] Furthermore, by integrating channel steel feeding, forward and reverse flipping, punching, female head welding, posture reversal, gasket assembly, and assembly welding into a continuous production line, the traditional process separation and independent equipment layout mode is abandoned. This eliminates frequent workpiece transfer, multiple loading and unloading, and repetitive positioning, reduces auxiliary time, unifies the processing benchmark of the entire production line, eliminates the cumulative positioning error caused by multiple clamping, improves the consistency of truss finished product dimensions, and increases welding efficiency.

A movable cylinder 309 is provided at the bottom end of the rack 308, and a movable table 304 is provided at the bottom end of a set of mounting brackets 301; the two ends of the tilting shaft 306 pass through the interior of two sets of fixed seats 305, and the tilting shaft 306 and the two sets of fixed seats 305 form a movable connection; a number of teeth are provided on one side of the rack 308, and the gear 307 meshes with the outer side of the rack 308; a feeding clamp 302 is provided at the top of both ends of the tilting shaft 306, and two sets of feeding clamps 302 are provided, which are symmetrically distributed on both sides of the top of the tilting shaft 306; two sets of tilting shafts 306 are provided, which are symmetrically distributed on both sides of the conveyor belt 303.

[0022] When welding the channel steel of the truss components, the channel steel to be processed is first neatly placed on the top of the feeding rack 1. After it is placed in place, the bottom guide rail assembly of the feeding rack 1 is activated to transport the feeding rack 1 carrying the channel steel to the bottom side of the first gantry gripping assembly 2. After it is transported to the position, the electromagnet adsorption clamp at the bottom of the first gantry gripping assembly 2 is activated to stably clamp and grip the channel steel on the feeding rack 1 by electromagnetic adsorption. After the gripping is completed, the first gantry gripping assembly 2 drives the channel steel to move above the conveyor belt 303 through the electromagnet adsorption clamp. Since the channel steel has a different installation orientation, if the channel steel is in the forward position, it can be directly placed inside the limiting seat at the top of the conveyor belt 303 for subsequent processes. If the channel steel is in the reverse position, it must be flipped to the forward position before the subsequent punching operation can be carried out. When it is necessary to flip the channel steel, first place the channel steel on the feeding clamp 302 on the side of the conveyor belt 303. After it is placed in place, start the side moving cylinder 309. After the moving cylinder 309 is started, it pushes the rack 308 to move upward. The rack 308 is driven by the outer teeth to mesh with the gear 307, which in turn drives the gear 307 to rotate. During the rotation of the gear 307, it drives the flipping shaft 306 to rotate inside the fixed seat 305. The flipping shaft 306 simultaneously drives the feeding clamp 302 to flip as a whole, thereby flipping the reversed channel steel to the forward position and smoothly falling into the limiting seat on the surface of the conveyor belt 303, completing the automatic flipping operation of the channel steel. The channel steel with its posture corrected to the positive direction is moved by the conveyor belt 303 to the unloading clamp 302 station on the other side. At this time, the end of the channel steel needs to be punched. During the punching operation, the moving table 304 at the bottom of the mounting frame 301 on the other side is started. The moving table 304 drives the mounting frame 301 to move laterally, so that the end of the channel steel is accurately fed into the processing area of ​​the punching component 9. After the alignment is completed, the punching component 9 is started and punches the end of the channel steel through the internal punching head. After the punching process is completed, the moving table 304 drives the mounting frame 301 to reset. Then the moving cylinder 309 at the top of the mounting frame 301 on the other side is started again. Through the meshing transmission of the rack 308 and the gear 307, the unloading clamp 302 is driven to flip and transfer the punched channel steel to the limit seat on the surface of the first conveyor frame 4. This device, by setting a flipping mechanism on the side of the conveyor belt 303, consisting of a feeding clamp 302, a flipping shaft 306, a gear 307, a rack 308, and a moving cylinder 309, can automatically correct the posture of the reversed channel steel without the need for manual flipping and adjustment, effectively reducing the intensity of manual labor, avoiding placement deviations and workpiece deformation caused by manual operation, ensuring the uniform processing posture of each channel steel, and providing a stable processing benchmark for subsequent punching processes. This equipment integrates posture correction, conveying, punching, and material transfer processes. After the channel steel is conveyed and positioned by the conveyor belt 303, it is precisely fed by the mounting frame 301 driven by the moving table 304, so that the end of the channel steel is stably fed into the punching component 9 to complete the punching operation. The process is closely connected, eliminating the need for multiple transfers and repeated clamping, which greatly shortens the processing flow time and significantly improves the automation level and processing efficiency of the production line. Relying on the mechanical flipping structure driven by the moving cylinder 309 to drive the rack 308 and gear 307, the operation is stable and highly repeatable. It can accurately control the flipping angle of the unloading clamp 302, effectively eliminating manual alignment errors and ensuring high consistency in the punching position and flipping posture of the same batch of channel steel, thereby improving the overall processing accuracy of the product. After punching, the material is flipped and fed again by the feeding clamp 302, which can smoothly transfer the processed channel steel to the first feeding rack 4, realizing continuous automated feeding, flipping, punching and material transfer production line operation. This effectively solves the problems of cumbersome, poor connection and low efficiency of traditional discrete processes, adapts to the continuous and automated production needs of the intelligent manufacturing equipment industry, and ensures the assembly accuracy and welding quality of subsequent female head assembly and welding processes. After the punched channel steel is transferred to the first conveyor rack 4 station, the six-axis gripping robot on the side of the female end material tray rack 8 accurately picks up the female end accessory at the top of the female end material tray rack 8 and assembles it to the punching position of the channel steel. After the female end is assembled, the six-axis automatic welding robot matched with the female end material tray rack 8 starts to weld and fix the connection position between the assembled female end and the channel steel. After the female end is welded, the channel steel continues to be transported to the next station with the first conveyor rack 4 to carry out the subsequent overall welding processing.

[0023] Reference Figures 1-10 As shown, the alignment and flipping structure 5 includes a fixing frame 501, which is installed on one side of the bottom end of the first conveying frame 4. A first cylinder 502 is provided on one side of the top end of the fixing frame 501, and a first connecting frame 503 is provided on the top end of the first cylinder 502. A first clamping claw 504 is provided on the top end of the first connecting frame 503. A second cylinder 507 is provided on the other side of the top end of the fixing frame 501, and a second connecting frame 506 is provided on the top end of the second cylinder 507. A second clamping claw 505 is provided on the top end of the second connecting frame 506. The bottom ends of the first cylinder 502 and the second cylinder 507 are hinged to the top end of the fixing frame 501. Mounting plates 508 are provided on both sides of the top end of the fixing frame 501. The two sets of mounting plates 508 are respectively connected to the bottom sides of the first connecting frame 503 and the first connecting frame 504. The two connecting frames 506 are hinged to each other on both sides at the bottom. Two sets of first clamping claws 504 and second clamping claws 505 are provided, and the two sets of first clamping claws 504 and second clamping claws 505 are symmetrically distributed on both sides of the top of the first connecting frame 503 and the second connecting frame 506, respectively. An electromagnet adsorption clamp is provided on one side of the first gantry gripping assembly 2. Limit seats are provided on the surfaces of the first conveying frame 4 and the second conveying frame 11. An electromagnet adsorption clamp is provided at the bottom of the second gantry gripping assembly 10. Multiple sets of channel steel are provided at the top of the unloading frame 1, and the multiple sets of channel steel are arranged at equal intervals at the top of the unloading frame 1. Two sets of unloading platform 6 and welding assembly 7 are provided at the bottom of the second gantry gripping assembly 10, and the two sets of unloading platform 6 and welding assembly 7 are symmetrically distributed at the bottom of the second gantry gripping assembly 10. Subsequent channel steel welding operations require the support surfaces of the two sets of channel steels to be aligned and fitted together before welding. Therefore, when the punched channel steel is transported above the second clamping claw 505, the movable cylinder at the bottom of the second clamping claw 505 is activated to lift the second clamping claw 505 upward as a whole, so that the second clamping claw 505 lifts the channel steel away from the conveying station. After the channel steel is lifted into place, the second cylinder 507 on one side of the second connecting frame 506 is activated. The second cylinder 507 pushes the second connecting frame 506 to rotate laterally inside the mounting plate 508, thereby driving the second clamping claw 505 and the top channel steel to rotate synchronously, so that the channel steel is adjusted in posture and falls smoothly onto the surface of the second conveying frame 11. Similarly, when another set of channel steel is conveyed to the top of the first clamping claw 504, the movable cylinder at the bottom of the first clamping claw 504 is activated to lift the first clamping claw 504 upward and support the channel steel. After the channel steel is lifted into place, the first cylinder 502 is activated to drive the first connecting frame 503 to reverse inside the mounting plate 508 through the same transmission principle as above, so that the same set of channel steel also flips and falls onto the surface of the second conveying frame 11. Through the symmetrical reverse flipping cooperation of the first clamping claw 504 and the second clamping claw 505, the support surfaces of the two sets of channel steel can be precisely set to face each other to meet the posture requirements for subsequent butt welding. After the two sets of channel steel complete the alignment conveying on the second material conveying frame 11, the electromagnet adsorption gripper at the bottom end of the second gantry grabbing assembly 10 is started to integrally adsorb and clamp the two sets of channel steel in the aligned state, and transfer and place them to the station at the top end of the welding assembly 7. After the placement is completed, the two sets of channel steel are positioned, clamped and fixed by the welding assembly 7, then the adsorption robot on one side of the material placing table 6 is started to accurately place the small rectangular block gaskets on the top of the material placing table 6 at the intermediate butt joint position of the two sets of channel steel; A bidirectional turnover mechanism is composed of the first clamping jaw 504, the second clamping jaw 505, the first cylinder 502, the second cylinder 507, the first connecting frame 503, the second connecting frame 506 and the mounting plate 508, which can adjust the postures of the two sets of channel steel respectively, so that the supporting surfaces of the channel steel are arranged opposite to each other, eliminating the manual alignment process and forming a stable welding reference; After the gasket is assembled in place, the welding robot matched with the welding assembly 7 is started to perform integral fusion welding on the butt joint position of the channel steel and the position of the gasket. After the welding process is completed, the electromagnet adsorption gripper at the bottom end of the second gantry grabbing assembly 10 is used again to transfer the welded and formed truss member to the conveying equipment of the next process, so as to fully realize the integrated automatic processing flow of channel steel feeding, turnover alignment, punching, assembly and welding, effectively simplify the traditional decentralized processing procedures, and greatly improve the overall processing and welding production efficiency of truss channel steel; Multiple processes including channel steel feeding, forward and reverse turnover, punching, posture reversing, gasket assembly, and assembly welding are integrated into an integrated production line, which abandons the traditional processing mode of independently arranged equipment and discrete processes, eliminates the frequent workpiece transfer, multiple loading and unloading and repeated positioning processes, greatly reduces the auxiliary working hours, accelerates the production rhythm, adopts continuous assembly line operation in the whole process, unifies the processing reference, effectively avoids the cumulative positioning error caused by multiple clamping, improves the dimensional consistency of finished truss products, stabilizes the processing quality, reduces the occupation of semi-finished product stacking areas and material transfer channels between each process, improves the utilization rate of plant space, facilitates large-scale centralized production, reduces the operation requirements for manual transfer, manual alignment and manual loading and unloading, reduces the number of operators, lowers the labor intensity, and at the same time avoids problems such as workpiece collision deformation and placement misalignment caused by manual operation. The entire production line realizes automatic continuous collaborative processing, conforms to the intelligent upgrading direction of the intelligent manufacturing equipment industry, facilitates the unified control of production rhythm, improves the overall processing capacity of truss channel steel, and effectively solves the problems of cumbersome procedures and low efficiency of the traditional decentralized processing mode.
