Description

Technical Field

[0001] This utility model relates to the field of welding workstations, and in particular to a storage shelf panel welding workstation. Background Technology

[0002] The storage shelf panel is welded from a wire mesh panel, two long side rails, two short side rails, and four conical sleeves. Before welding the long and short side rails to the wire mesh panel, they need to be loaded and positioned. Traditionally, the positioning of the long and short side rails and wire mesh panel involves manually placing them onto corresponding clamping fixtures of different specifications for fixation before welding with a welding machine. This method results in low welding efficiency, high cost of clamping fixtures, and poor versatility. Furthermore, misalignment is prone to occur when placing the long and short side rails and wire mesh panel onto the clamping fixtures, leading to poor positioning accuracy, low welding precision, poor welding effect, low yield, and high cost. In addition, the manual handling of the long and short side rails and wire mesh panel at the welding station and the unloading of finished products is prone to occupational safety accidents and is not conducive to the development of industrial automation. Currently, there is no equipment on the market that can automatically produce shelves of different shapes. Therefore, the industry urgently hopes to develop a device that can automatically produce shelves of different shapes. Summary of the Invention

[0031] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0032] 1. By designing the structures of the first and second side rail loading and flipping conveyor mechanisms, the first side rail loading and flipping conveyor can automatically load, distribute, flip, and transfer long side rails of different lengths one by one, and the second side rail loading and flipping conveyor can automatically load, distribute, flip, and transfer short side rails of different lengths one by one. This avoids deformation of the side rails during the conveying process, which would affect the subsequent welding effect. It has the advantages of high loading and conveying efficiency, high distribution efficiency, high flipping efficiency, high positioning accuracy, and strong versatility. It solves the problems of low work efficiency, high labor intensity of workers, and high labor costs of enterprises caused by the traditional manual handling and loading of long and short side rails.

[0033] 2. By designing the structure of the welding positioning mechanism and coordinating the welding positioning mechanism, the mesh conveying mechanism, the first side rail loading and flipping conveying mechanism, and the second side rail loading and flipping conveying mechanism, the mesh is automatically loaded and conveyed through the mesh conveying mechanism. This allows mesh of different specifications to be automatically and accurately docked with long side rails and short side rails of different lengths, achieving high versatility and automation. It also ensures good welding quality for mesh of different specifications with long and short side rails of different lengths. This effectively solves the problems of poor docking and positioning accuracy, low welding accuracy, poor welding effect, low yield, and high cost of clamping fixtures caused by the traditional method of manually placing long side rails, short side rails, and mesh on corresponding clamping fixtures of different specifications.

[0034] 3. By providing several stacking mechanisms for stacking shelves on one side of the shelf conveying mechanism and a shelf positioning mechanism on the side of the mesh conveying mechanism away from the welding positioning mechanism, and by designing the structures of the stacking and positioning mechanisms separately, it not only enables automated stacking of shelves for mesh frames of different shapes and automated detection of the stacking height, thus achieving strong versatility and ensuring that the height of each stack of shelves remains consistent, but also greatly increases the number of stacked shelves to save space, and gives the shelves the advantages of accurate stacking positioning and good stacking effect, thereby solving the problem that there is currently no equipment capable of stacking shelves for mesh frames of different shapes.

[0035] 4. Its overall structural design enables automated production of shelves from long side rails of different lengths, short side rails of different lengths, and wire mesh panels of different specifications on a single machine. It can also automatically stack finished shelves according to wire mesh frames of different shapes, achieving high versatility and a high degree of automation. It has the advantages of high production efficiency, good welding effect, and high finished product yield. Furthermore, it greatly reduces the occurrence of production accidents and solves the problem that there is currently no equipment on the market that can fully automatically complete the production of shelves.

The side rail loading moving frame 42 is laterally slidably mounted on the side rail loading base 40 via several parallel first linear guide rails 41. The side rail loading mechanism 44 is mounted on one end of the side rail loading moving frame 42 via two side rail loading uprights 43 and is used to provide side rail loading. A side rail conveying mechanism 45 is installed on the top of the side rail loading moving frame 42 and is used to convey the side rail. A first side rail flipping mechanism 46 and a second side rail flipping mechanism 47 are installed on the top of the side rail loading moving frame 42 and are located on both sides of the side rail conveying mechanism 45, respectively. The first side rail flipping mechanism 46 and the second side rail flipping mechanism 47 clamp the two ends of the side rail and flip the side rail. A first side rail transfer positioning mechanism 48 and a second side rail transfer positioning mechanism 49 are installed on the other end of the side rail loading moving frame 42 and are located on both sides of the side rail conveying mechanism 45, respectively. The first side rail transfer positioning mechanism 48 and the second side rail transfer positioning mechanism 49 clamp and fix the two ends of the side rail, respectively.

[0067] By adopting the above technical solution, the first side rail feeding and flipping conveying mechanism 4 is responsible for feeding, distributing, flipping, and conveying the long side rails. The side rail feeding mechanism 44 supplies the long side rails. The side rail conveying mechanism 45 receives the long side rails from the side rail feeding mechanism 44 and conveys them to the first side rail flipping mechanism 46 and the second side rail flipping mechanism 47. The first side rail flipping mechanism 46 and the second side rail flipping mechanism 47 respectively clamp the two ends of the long side rails and flip them. The side rail conveying mechanism 45 receives the long side rails from the first side rail flipping mechanism 46 and the second side rail flipping mechanism 47 and conveys them to the first side rail transfer positioning mechanism 48 and the second side rail transfer positioning mechanism 49. The first side rail transfer positioning mechanism... The first side rail transfer positioning mechanism 48 and the second side rail transfer positioning mechanism 49 clamp and fix the two ends of the long side rail respectively for transfer positioning. The side rail conveying mechanism 45 takes the long side rail from the first side rail transfer positioning mechanism 48 and the second side rail transfer positioning mechanism 49 and conveys it to the first welding machine 1 for pre-welding positioning. This realizes the 180-degree rotation of the long side rail to meet the correct orientation required for welding positioning. It has the advantages of high material conveying efficiency, good positioning effect and accurate positioning. It solves the problems of low material conveying efficiency, poor positioning accuracy, poor positioning effect, high labor intensity of workers and high labor cost of enterprises caused by the traditional manual handling, manual feeding and manual placement of long side rails.

[0071] Reference Figure 2 and Figure 5As shown, the side rail feeding mechanism 44 includes a first guide rod 440, a second guide rod 441, a first gantry frame 442, a second gantry frame 443, a first upper guide plate positioning assembly 444, a second upper guide plate positioning assembly 445, a first linear guide rail positioning assembly 446, a second linear guide rail positioning assembly 447, at least one wave-shaped guide rail positioning and adjusting assembly 448, at least one side rail blocking assembly 4401, two side rail distributing assemblies 4402, two side rail feeding blocking assemblies 4403, and at least one side rail pushing assembly 4404; the first guide rod 440 and the second guide rod 441... 1. The first guide rod 441 is vertically connected to two side rail feeding uprights 43, and its horizontal height is higher than that of the first guide rod 440. The first gantry frame 442 and the second gantry frame 443 are vertically connected to the two side rail feeding uprights 43, respectively. Locking components 449 are installed on both ends of the crossbeam of the first gantry frame 442, and at least one locking component 449 is installed on the middle of the crossbeam of the first gantry frame 442.

[0072] Reference Figure 5 As shown, the locking assembly 449 includes a handle screw 4491 and a positioning frame 4492. The bottom inner side of the positioning frame 4492 is connected and installed with the slider of the second linear guide 4405 or the slider of the third linear guide 4406. The handle screw 4491 is vertically threaded onto the top of the positioning frame 4492.

[0073] Reference Figure 6As shown, the first linear guide rail positioning assembly 446 includes a first guide sleeve 4460, two first locking rings 4461, a second guide sleeve 4462, two second locking rings 4463, a linear guide rail mounting tube 4464, a first linear guide rail 4465, a second linear guide rail 4466, a first linear rod end limiting plate 4467, and a linear rod side stop 4468. The linear guide rail mounting tube 4464 is obliquely mounted on the first guide rod 440 and the second guide rod 441 via the first guide sleeve 4460 and the second guide sleeve 4462, respectively. The two first locking rings 4461 are mounted on the first guide rod 440 and are located on both sides of the first guide sleeve 4460, and the two second locking rings 4463 are mounted on the second guide rod 441 and are located on both sides of the second guide sleeve 4462. The two first locking rings 4461 respectively position the first linear rod end limiting plate 4467 and the linear rod side stop 4468. A guide sleeve 4460 slides on the first guide rod 440 to limit its movement. Two second locking rings 4463 respectively limit the sliding movement of the second guide sleeve 4462 on the second guide rod 441. A first linear guide rail 4465 is obliquely mounted on the upper inclined surface of the linear guide rail mounting tube 4464. A second linear guide rail 4466 is horizontally mounted on the top of the linear guide rail mounting tube 4464. A first linear rod end limiting plate 4467 is mounted on the linear guide rail mounting tube 4464 and located outside the second linear guide rail 4466. A linear rod side stop bar 4468 is mounted on the linear guide rail mounting tube 4464 and located outside the end of the second linear guide rail 4466. The structure and working principle of the second linear guide rail positioning assembly 447 are the same as those of the first linear guide rail positioning assembly 446.

[0074] By adopting the above technical solution, the first guide sleeve 4460 is positioned and fixed on the first guide rod 440 by two first locking rings 4461, and the second guide sleeve 4462 is positioned and fixed on the second guide rod 441 by two second locking rings 4463. This allows for adaptive adjustment of the feeding of long side rails of different lengths, thereby meeting the feeding and conveying needs of long side rails of different lengths. The long side rails are placed on the second straight rod guide rail 4466 of the first straight rod guide rail positioning assembly 446 and the second straight rod guide rail positioning assembly 447, and the second wave-shaped rod guide rail 4489 of the wave-shaped rod guide rail positioning adjustment assembly 448 for preparation. When the long side rail is pushed onto the first straight rod guide rail 4465 of the first straight rod guide rail positioning assembly 446 and the second straight rod guide rail positioning assembly 447, and the first wave-shaped rod guide rail 4487 of the wave-shaped rod guide rail positioning adjustment assembly 448, the long side rail, under its own weight, is positioned on the first straight rod guide rail positioning assembly 446 and the second straight rod guide rail positioning assembly 447. Material is fed by sliding conveyor on the first linear guide rail 4465 of the linear guide rail positioning assembly 447 and the first wave guide rail 4487 of the wave guide rail positioning adjustment assembly 448. The first upper guide plate positioning assembly 444 and the second upper guide plate positioning assembly 445 limit the side ends and top of the linear rods of the long side rail. The wave guide rail positioning adjustment assembly 448 supports and conducts the wave rods of the long side rail, ensuring that the long side rail is fed in a flat and orderly manner. The side rail material distribution assembly 4402 blocks the first long side rail for material distribution and preparation. The side rail blocking assembly 44... 01 blocks the second longest side rail. After the side rail distribution component 4402 releases the first longest side rail, it resets. The two side rail feeding blocking components 4403 block the first longest side rail to prepare material before pushing the long side rail. The side rail pushing component 4404 pushes the first longest side rail to the side rail conveying mechanism 45 to realize the long side rail pushing. At the same time, when the third photoelectric proximity switch 4444 in the first upper guide plate positioning component 444 senses that there is a lack of a long side rail between the side rail distribution component 4402 and the side rail blocking component 4401, the side rail blocking component 4401 releases its obstruction. The long side rail resets to block the next long side rail. When the third photoelectric proximity switch 4444 senses the lack of a long side rail, it reminds the worker to place a long side rail for material preparation. This realizes fully automatic and orderly material feeding, fully automatic material distribution, and fully automatic pushing of long side rails. It has the advantages of high feeding efficiency, smooth feeding, accurate material distribution, high material distribution efficiency, good material distribution effect, and high degree of automation in material distribution and pushing. It solves the problems of low feeding efficiency, low material distribution efficiency, low material distribution accuracy, low degree of automation, high labor intensity for workers, and high labor costs for enterprises caused by traditional manual material feeding of long side rails.

[0075] Reference Figure 6 and Figure 7As shown, the wave bar guide rail positioning and adjustment assembly 448 includes a third guide sleeve 4480, two third locking rings 4481, a fourth guide sleeve 4482, two fourth locking rings 4483, a wave bar guide rail positioning tube 4484, at least one manual rocker ball screw 4485, at least one first guide post and guide sleeve assembly 4486, at least one first wave bar guide rail 4487, a first wave bar mounting plate 4488, at least one second wave bar guide rail 4489, and a second wave bar mounting plate 44891. The guide rail positioning tube 4484 is obliquely mounted on the first guide rod 440 and the second guide rod 441 via the third guide sleeve 4480 and the fourth guide sleeve 4482, respectively. Two third locking rings 4481 are mounted on the first guide rod 440 and located on both sides of the third guide sleeve 4480, and two fourth locking rings 4483 are mounted on the second guide rod 441 and located on both sides of the fourth guide sleeve 4482. The first wave rod mounting plate 4488 is obliquely mounted on the upper inclined surface of the wave rod guide rail positioning tube 4484, and the second wave rod mounting plate 4488 is mounted on the upper inclined surface of the wave rod guide rail positioning tube 4484. Mounting plate 44891 is horizontally mounted on the top of wave rod guide rail positioning tube 4484. First wave rod mounting plate 4488 is connected to second wave rod mounting plate 44891. At least one first wave rod guide rail 4487 is obliquely mounted on first wave rod mounting plate 4488, and at least one second wave rod guide rail 4489 is horizontally mounted on second wave rod mounting plate 44891. At least one first wave rod guide rail 4487 and at least one second wave rod guide rail 4489 are mated together. The first wave rod... Mounting plate 4488 is slidably mounted on wave bar guide rail positioning tube 4484 via at least one first guide post and guide sleeve assembly 4486. At least one hand-operated ball screw 4485 is mounted on wave bar guide rail positioning tube 4484 and the screw of the hand-operated ball screw 4485 is rotatably connected to the first wave bar mounting plate 4488. Rotating the hand-operated ball screw 4485 causes the first wave bar mounting plate 4488 to move up and down relative to the wave bar guide rail positioning tube 4484 on the first guide post and guide sleeve assembly 4486.

[0076] By adopting the above technical solution, the long side rail 44892 is placed on the second wave-shaped guide rail 4489 for long side rail preparation. When the long side rail 44892 is pushed onto the first wave-shaped guide rail 4487, the long side rail 44892 slides and is conveyed on the first wave-shaped guide rail 4487 under its own gravity for long side rail feeding. The first wave-shaped mounting plate 4488 is driven to slide up and down on the first guide post and guide sleeve assembly 4486 by the hand-operated ball screw 4485. The height of the first wave-shaped guide rail 4487 and the second wave-shaped guide rail 4489 are adjusted. The height difference between the first wave guide rail 4487 and the first straight guide rail 4465 is the same as the height difference between the bottom of the straight rod 44893 and the bottom of the wave crest of the wave rod 44894 in the long side rail 44892. This prevents the long side rail 44892 from deforming during free conveying due to its own weight being suspended by the first wave guide rail 4487 or the first straight guide rail 4465. This ensures stable, smooth, and efficient material conveying of the long side rail, and is suitable for smooth conveying of long side rails of different specifications, thus achieving its versatility.

[0077] Reference Figure 8 As shown, the first upper guide plate positioning assembly 444 includes an upper guide plate mounting tube 4440, a linear rod upper guide plate 4441, and a second linear rod end limiting plate 4442. The upper guide plate mounting tube 4440 is installed at the bottom of the locking assembly 449 on the same end of the first gantry 442 and the second gantry 443. The linear rod upper guide plate 4441 is installed inside the upper guide plate mounting tube 4440 and is used to limit the top of the linear rod. A second photoelectric proximity switch 4443 and a third photoelectric proximity switch 4444 are respectively installed on the linear rod upper guide plate 4441 along a straight line. The second linear rod end limiting plate 4442 is installed at the bottom of the linear rod upper guide plate 4441 and is used to limit the end of the linear rod. The structure and working principle of the second upper guide plate positioning assembly 445 are the same as those of the first upper guide plate positioning assembly 444.

[0078] By adopting the above technical solution, the upper guide plate 4441 of the straight rod limits the top of the straight rod of the long side rail, and the end limiting plate 4442 of the second straight rod limits the end of the straight rod of the long side rail, thus preventing the long side rail from being misaligned or offset during free transmission. At the same time, the first wave rod guide rail 4487 and the first straight rod guide rail 4465 are parallel to each other and play a guiding role in the free transmission of the long side rail, ensuring that the long side rail is always perpendicular to the first wave rod guide rail 4487 and the first straight rod guide rail 4465 during free transmission, thus preventing the long side rail from being tilted, misaligned, or derailed during free transmission. Each side rail can be automatically and orderly transmitted freely, and has the advantages of high transmission efficiency and high transmission accuracy.

[0079] Reference Figure 9As shown, the side rail blocking assembly 4401 includes a first side rail baffle lifting drive device 44011 and a first side rail baffle 44012. The first side rail baffle lifting drive device 44011 is vertically installed at the bottom of the locking assembly 449 in the middle of the crossbeam of the first gantry frame 442, and the first side rail baffle 44012 is installed on the output end of the first side rail baffle lifting drive device 44011.

[0080] By adopting the above technical solution, the first side rail baffle lifting drive device 44011 drives the first side rail baffle 44012 to rise and release the current long side rail to provide the long side rail to the side rail distribution component 4402. The first side rail baffle lifting drive device 44011 drives the first side rail baffle 44012 to insert into the gap between two adjacent long side rails to separate the current long side rail from the next long side rail, ensuring that the long side rails are automatically distributed one by one. In this embodiment, the first side rail baffle lifting drive device 44011 is set as a cylinder.

[0082] By adopting the above technical solution, the second side rail baffle lifting drive device 44022 drives the second side rail baffle 44023 to rise to block the long side rail from the side rail blocking assembly 4401, and the second side rail baffle lifting drive device 44022 drives the second side rail baffle 44023 to fall to distribute the long side rail, so as to realize the automated distribution of the long side rail by the side rail material distribution assembly 4402. In this embodiment, the second side rail baffle lifting drive device 44022 is set as a cylinder.

[0083] Reference Figure 11 As shown, the side rail feeding blocking assembly 4403 includes a blocking mounting base 44031, a stop bar support 44032, a spring 44033, and a stop bar 44034. The stop bar support 44032 is fixed to the bottom of the locking assembly 449 on both ends of the crossbeam of the first gantry frame 442 through the blocking mounting base 44031. The stop bar 44034 is rotatably mounted on the bottom of the stop bar support 44032. One end of the spring 44033 is connected to the blocking mounting base 44031, and the other end of the spring 44033 is connected to the stop bar 44034.

[0084] By adopting the above technical solution, the baffle 44034 blocks the long side rail from the side rail feeding component 4402 to realize fully automatic material preparation before pushing the long side rail.

[0085] Reference Figure 12 As shown, the side rail pushing assembly 4404 includes a side rail horizontal movement drive device 44041, a push mounting base 44042, a side rail lifting drive device 44043, a lifting drive device mounting plate 44044, a first side rail clamping drive device 44045, and two first side rail clamping arms 44046. The side rail horizontal movement drive device 44041 is mounted on the bottom of the locking assembly 449 in the middle of the crossbeam of the first gantry frame 442 via the push mounting base 44042.

The first side rail clamping drive device 44045 is vertically mounted on the output end of the side rail lifting drive device 44043, and two second guide post and guide sleeve assemblies 44040 are mounted on the lifting drive device mounting plate 44044. The two second guide post and guide sleeve assemblies 44040 are located on the two side rail lifting drive devices 44043, and the lower ends of the two second guide post and guide sleeve assemblies 44040 are respectively connected and installed to the first side rail clamping drive device 44045. Two first side rail clamping arms 44046 are respectively mounted on the output end of the first side rail clamping drive device 44045.

[0086] By adopting the above technical solution, the side rail lifting drive device 44043 drives the first side rail clamping drive device 44045 to descend, the first side rail clamping drive device 44045 drives the two first side rail clamping arms 44046 to clamp the long side rail, and the side rail lateral movement drive device 44041 drives the two first side rail clamping arms 44046 to move forward to push the long side rail. The long side rail passes through the stop bar 44034 and is placed on the side rail conveying mechanism 45, realizing fully automatic sequential and orderly pushing of long side rails one by one. In this embodiment, both the side rail lifting drive device 44043 and the side rail lateral movement drive device 44041 are set as cylinders, and the first side rail clamping drive device 44045 is set as a finger clamping cylinder.

The third side rail clamping assembly 4505 and the fourth side rail clamping assembly 4506, the linear module 450 is mounted on the side rail loading moving frame 42, the side rail transfer base plate 451 is mounted on the sliding part of the linear module 450, at least two third guide post and guide sleeve assemblies 456 are longitudinally mounted on the side rail transfer base plate 451, the side rail lifting plate 457 is mounted on the top of the guide rods of at least two third guide post and guide sleeve assemblies 456, and the side rail clamping assembly lifting drive device 458 is longitudinally mounted on the side rail transfer base plate 451 and clamps the side rail. The output end of the component lifting drive device 458 is connected and installed to the side rail lifting plate 457. The first clamping component mounting bracket 4501 is horizontally mounted on one side of the side rail lifting plate 457. The two-dimensional slide table 459 is mounted on the same side of the side rail lifting plate 457. The second clamping component mounting bracket 4502 is horizontally mounted on the two-dimensional slide table 459 and is arranged parallel to the first clamping component mounting bracket 4501. The first side rail clamping component 4503 and the second side rail clamping component 4504 are respectively vertically mounted on the top of the side rail lifting plate 457. On the surface, the third side rail clamping assembly 4505 and the fourth side rail clamping assembly 4506 are respectively longitudinally mounted on one end of the first clamping assembly mounting frame 4501 and the second clamping assembly mounting frame 4502; the first side rail clamping assembly 4503, the second side rail clamping assembly 4504, the third side rail clamping assembly 4505 and the fourth side rail clamping assembly 4506 respectively include a second side rail clamping drive device 4507 and two second side rail clamping arms 4508 mounted on the output end of the second side rail clamping drive device 4507.

[0088] By adopting the above technical solution, the first side rail clamping assembly 4503 and the second side rail clamping assembly 4504 respectively drive their two second side rail clamping arms 4508 to clamp the long side rail. After clamping the long side rail, the linear module 450 moves the long side rail to below the first side rail flipping mechanism 46 and the second side rail flipping mechanism 47. The long side rail is raised to the position of the first side rail flipping mechanism 46 and the second side rail flipping mechanism 47 under the drive of the side rail clamping assembly lifting drive device 458. The first side rail flipping mechanism 46 and the second side rail flipping mechanism 47 take over the long side rail and flip it 180 degrees before releasing the long side rail. At the same time, the first side rail clamping assembly 4503 and the second side rail clamping assembly 4504 clamp the flipped long side rail. The linear module 450 and the side rail clamping assembly lifting drive device 458 work together to transfer the flipped long side rail to the first side rail transfer positioning mechanism 48 and the second side rail transfer positioning mechanism 49 for transfer positioning. The linear module 450... The lifting drive device 458 of the side rail clamping assembly and the 50 work together to drive the first side rail clamping assembly 4503 and the second side rail clamping assembly 4504 backward, and allow the third side rail clamping assembly 4505 and the fourth side rail clamping assembly 4506 to take over the long side rail from the first side rail transfer positioning mechanism 48 and the second side rail transfer positioning mechanism 49 and transfer it to the first welding machine 1. This automates the receiving of the long side rail, the delivery of the long side rail to the first side rail flipping mechanism 46 and the second side rail flipping mechanism 47, and the receiving of the flipped long side rail. The first side rail transfer positioning mechanism 48 and the second side rail transfer positioning mechanism 49 are used to realize the transfer of the flipped long side rail from the first side rail clamping assembly 4503 and the second side rail clamping assembly 4504 to the third side rail clamping assembly 4505 and the fourth side rail clamping assembly 4506. Finally, the long side rail is automatically transferred to the first welding machine 1 over a long distance, avoiding the trouble of manually handling and transferring the long side rail.

On the output end of the flipping drive device 467, the first linear rod clamping arm 469 and the second linear rod clamping arm 4691 are respectively mounted on the output end of the third side rail clamping drive device 468; the side of the second linear rod clamping arm 4691 opposite to the first linear rod clamping arm 469 is provided with a large V-groove 4692, and a guide groove 4693 perpendicular to the large V-groove 4692 is provided on the second linear rod clamping arm 4691; the side of the first linear rod clamping arm 469 opposite to the second linear rod clamping arm 4691 is provided with an outwardly protruding integrally formed ridge, the ridge... The shape is adapted to the shape of the large V-groove 4692. The first straight bar clamping arm 469 is integrally formed with a guide block 4694 that is perpendicular to the convex strip and extends outward. The guide block 4694 and the convex strip are recessed with a small V-groove 4695. The small V-groove 4695 and the large V-groove 4692 are arranged opposite to each other and are used to clamp the straight bar of the side rail. The structure of the second side rail flipping mechanism 47 is mirror symmetrical to the structure of the first side rail flipping mechanism 46. The working principle of the second side rail flipping mechanism 47 is the same as that of the first side rail flipping mechanism 46.

[0091] By adopting the above technical solution, the relative spacing and position of the third side rail clamping drive device 468 of the first side rail flipping mechanism 46 and the second side rail flipping mechanism 47 can be adjusted by the first transverse manual slide 463 and the first longitudinal manual slide 464, so that the third side rail clamping drive device 468 of the first side rail flipping mechanism 46 and the second side rail flipping mechanism 47 are on the same straight line, so as to meet the flipping of long side rails of different lengths, which has strong versatility; the third side rail clamping drive device 468 drives the first straight rod clamping arm 469 and the second straight rod clamping arm 4691 to clamp the end of the straight rod of the long side rail to receive the long side rail. When the side rail flipping drive device 467 of the first side rail flipping mechanism 46 and the second side rail flipping mechanism 47 drives the first straight rod clamping arm 469 and the second straight rod... After the clamping arm 4691 rotates, causing the long side rail to flip 180 degrees, the third side rail clamping drive device 468 of the first side rail flipping mechanism 46 and the second side rail flipping mechanism 47 drives the first linear clamping arm 469 and the second linear clamping arm 4691 to release the end of the long side rail. The long side rail falls to the side rail conveying mechanism 45 for subsequent conveying. The flipped long side rail is in the swing direction required for welding. The structural design of the first side rail flipping mechanism 46 meets the requirements for flipping and adjusting the swing direction of long side rails of different lengths. It has the advantages of strong versatility, high flipping efficiency, high flipping accuracy, and good flipping effect. It avoids the problems of low flipping efficiency, low degree of automation, high labor intensity of workers, and high labor costs of enterprises caused by the traditional manual flipping and swing adjustment of long side rails.

The structure of the second side rail transfer positioning mechanism 49 is mirror-symmetrical to the structure of the first side rail transfer positioning mechanism 48. The working principle of the second side rail transfer positioning mechanism 49 is the same as that of the first side rail transfer positioning mechanism 48.

[0093] By adopting the above technical solution, the distance and relative position between the mounting plates 483 of the rotating drive device of the first side rail transfer positioning mechanism 48 and the second side rail transfer positioning mechanism 49 can be adjusted by the second transverse manual slide 480 and the second longitudinal manual slide 482, so that the mounting plates 483 of the rotating drive device of the first side rail transfer positioning mechanism 48 and the second side rail transfer positioning mechanism 49 are at the same height and on the same longitudinal plane. The pressure block rotating drive device 484 drives the side rail pressure block 485 to rotate and press the long side rail onto the rotating drive device mounting plate 483 to fix or loosen the long side rail. By setting the structures of the first side rail transfer positioning mechanism 48 and the second side rail transfer positioning mechanism 49 in a mirror symmetrical arrangement, the first side rail transfer positioning mechanism 48 and the second side rail transfer positioning mechanism 49 can jointly clamp the end of the long side rail, which has the advantage of stable clamping. The rotating drive mounting plate 483 has one or more side rail spinning components. This design can fix the end of a long side rail, so that the long side rail will not be deformed by its own weight, ensuring that its transfer positioning efficiency, transfer positioning accuracy and transfer positioning effect are good.

The structure and working principle of the second welding positioning assembly 33 are the same as those of the first welding positioning assembly 32.

[0098] By adopting the above technical solution, the iron rod positioning reference block 324 of the first welding positioning assembly 32 supports the mesh plate, and the iron rod pressing drive device 322 of the first welding positioning assembly 32 drives the iron rod pressing block 323 to push the mesh plate onto the first welding machine 1. Similarly, the iron rod positioning reference block 324 of the second welding positioning assembly 33 supports the mesh plate, and the iron rod pressing drive device 322 of the second welding positioning assembly 33 drives the iron rod pressing block 323 to push the mesh plate onto the second welding machine 2, so that the mesh plate and the long side rail and the short side rail automatically complete precise docking and positioning before welding. After docking and positioning, the long side rail and the short side rail... The welding effect between the railing and the mesh panel is good, with a high yield rate. It is suitable for automated docking and positioning of long and short side rails and mesh panels of different lengths, offering strong versatility. This reduces the high cost of clamping fixtures, lowers worker labor intensity, and reduces enterprise labor costs. It solves the problems of traditional manual placement of long and short side rails and mesh panels onto corresponding clamping fixtures of different specifications, which easily leads to deviations, poor docking and positioning accuracy, poor subsequent welding effects, low yield rate, high clamping fixture costs, high worker labor intensity, and high enterprise labor costs. In this embodiment, the iron rod clamping drive device 322 is set as a cylinder.

In this embodiment, the upper welding head lifting drive device 122 is a cylinder.

[0100] Reference Figure 22 and Figure 23 As shown, the first lower welding mechanism 13 includes a welding base 130, a lower welding head 131, a lower welding head mounting block 132, a side rail support rod 133, a support rod base 134, a support rod clamping plate 135, a fixing block translation drive device 136, a connecting plate 137, and a side rail fixing block 138.

The lower welding head 131 is mounted on one side of the welding base 130 via the lower welding head mounting block 132. The support rod base 134 is mounted on the other side of the welding base 130. The side rail support rod 133 is horizontally inserted through the top of the welding base 130 and... A through-welding head 131 and a support rod clamp 135 are mounted on a support rod base 134 to fix the side rail support rod 133 to the support rod base 134. A fixing block translation drive device 136 is horizontally mounted on the other side of the welding base 130 and located below the support rod base 134. The output end of the fixing block translation drive device 136 movably passes through the welding base 130. A side rail fixing block 138 is mounted on the output end of the fixing block translation drive device 136 via a connecting plate 137. The side rail fixing block 138 is provided with at least one support rod clearance groove 139 for avoiding the side rail support rod 133. The structure and working principle of the second upper welding mechanism 22 are the same as those of the first upper welding mechanism 12, and the structure and working principle of the second lower welding mechanism 23 are the same as those of the first lower welding mechanism 13.

[0101] By adopting the above technical solution, when the long side rail is conveyed to the side rail carrier 133 by the side rail conveying mechanism 45, the fixed block translation drive device 136 drives the side rail carrier 133 through the connecting plate 137 to limit the long side rail on the side rail carrier 133. When the side rail conveying mechanism 45 releases the long side rail, the fixed block translation drive device 136 drives the side rail carrier 133 through the connecting plate 137 to further press the long side rail against the side of the lower welding head 131, avoiding interference from the side rail conveying mechanism 45 clamping the long side rail and positioning it on the side rail carrier 133. This not only realizes the automated docking and positioning of the long side rail and the mesh plate, but also ensures high docking and positioning accuracy and high docking and positioning efficiency, thus solving the trouble of manually docking the long side rail, short side rail and mesh plate in the traditional method. In this embodiment, the fixed block translation drive device 136 is set as a cylinder.

[0102] Reference Figure 24 and Figure 25As shown, the shelf positioning mechanism 7 includes a shelf positioning bracket 70, a shelf positioning platform 71, a first side limiting plate 72, a fourth photoelectric proximity switch 73, a second side limiting plate 74, and a fifth photoelectric proximity switch 75. The shelf positioning platform 71 is mounted on the shelf positioning bracket 70. The first side limiting plate 72 is mounted on one side of the shelf positioning platform 71, and the second side limiting plate 74 is mounted on the other side of the shelf positioning platform 71. The first side limiting plate 72 and the second side limiting plate 74 are adjacent to each other and perpendicular to each other. The fourth photoelectric proximity switch 73 is mounted on the first side limiting plate 72 and is used to detect whether there is a shelf on the shelf positioning platform 71. The fifth photoelectric proximity switch 75 is mounted on the second side limiting plate 74 and is used to detect whether there is a shelf on the shelf positioning platform 71.

[0103] By adopting the above technical solution, the finished shelf is placed on the shelf positioning platform 71. The shelf slides on the shelf positioning platform 71 and is positioned with the first side limiting plate 72 and the second side limiting plate 74 as references. The fourth photoelectric proximity switch 73 and the fifth photoelectric proximity switch 75 detect whether the shelf positioning platform 71 has a shelf, and position it for subsequent stacking of the shelf. The structural design of the shelf positioning mechanism 7 greatly increases the number of shelf stacking layers to save space. At the same time, it also ensures high positioning accuracy of shelf stacking.

[0104] Reference Figure 24 and Figure 26 As shown, the stacking mechanism 9 includes a stacking base frame 90, several stacking limiting posts 91, several stacking adjusting seats 92, at least two sensor brackets 93, and at least two through-beam photoelectric sensors 94. The stacking limiting posts 91 are mounted on the stacking base frame 90 through the stacking adjusting seats 92. The sensor brackets 93 are respectively mounted on the outer sides of both ends of the stacking base frame 90, and the through-beam photoelectric sensors 94 are mounted on the sensor brackets 93.

[0105] By adopting the above technical solution, the shelf stacking mechanism 9 is used to stack shelves for storage. The stacking limiting posts 91 are installed on the edge of the stacking base frame 90 through the stacking adjustment seat 92. The stacking limiting posts 91 can be installed on the edge of the stacking base frame 90 according to the adaptability of different shaped grid frames (i.e., shelves) to limit the stacked shelves (i.e., several stacking limiting posts 91 can be arranged into different shapes according to production needs to limit different shaped grid frames), thus achieving the goals of strong versatility, good shelf stacking effect, and reduced material preparation costs. Two through-beam photoelectric sensors 94 automatically detect whether the stacked shelves on the stacking base 90 exceed the height of the detection position. When the two through-beam photoelectric sensors 94 detect shelves, they stop stacking shelves on the stacking base 90. This realizes automated stacking of shelves and automatic detection of the stacking height of shelves, avoiding excessive stacking of shelves and ensuring that the stacking height of shelves can be kept consistent. It has the advantages of high stacking efficiency and good stacking effect, thus solving the trouble of traditional manual stacking of shelves and the need for manual counting of the number of stacked layers.

[0106] Reference Figures 1 to 26As shown, this utility model also provides a workflow for a storage shelf welding workstation: the storage shelf is welded from a mesh panel, two long side rails, two short side rails, and four conical sleeves. A first side rail feeding and flipping conveyor 4 feeds and flips the long side rails to a first welding machine 1, which then performs pre-welding limiting and fixing. A second side rail feeding and flipping conveyor 5 feeds and flips the short side rails to a second welding machine 2, which also performs pre-welding limiting and fixing. Simultaneously, a mesh panel conveying mechanism 6 prepares and picks up the mesh panel and conveys it to a welding positioning mechanism 3, which limits and fixes the mesh panel to achieve automatic and precise docking and positioning with the long and short side rails respectively. The first welding machine 1 welds one long side of the long side rail and the mesh panel, and the second welding machine 2 welds one short side of the short side rail and the mesh panel. When the mesh panel... After the mesh plate is welded to one of the long and short side rails respectively, the mesh plate conveying mechanism 6 picks up the mesh plate from the welding positioning mechanism 3, rotates it 180 degrees, and then places it back into the welding positioning mechanism 3 for positioning and fixing. At the same time, the first side rail feeding and flipping conveying mechanism 4 conveys the next long side rail to the first welding machine 1, and the second side rail feeding and flipping conveying mechanism 5 conveys the next short side rail to the second welding machine 2, so that the other long and short sides of the mesh plate are automatically and accurately docked and positioned with the next long and the next short side rail respectively. The first welding machine 1 welds the current long side rail to the other long side of the mesh plate, and the second welding machine 2 welds the current short side rail to the other short side of the mesh plate. When the mesh plate is welded to the other long side rail and the other short side rail respectively, it becomes a finished shelf. The mesh plate conveying mechanism 6 picks up the finished shelf from the welding positioning mechanism 3 and places it into the shelf positioning mechanism 7 for pre-stacking positioning.The shelf conveying mechanism 8 picks up finished shelf panels from the shelf positioning mechanism 7 and places them onto the shelf stacking mechanism 9 for stacking. Its overall structural design enables automated, one-stop operation for orderly feeding and conveying of long side rails, short side rails, and mesh panels; automated material distribution and pushing of each side rail; automated pre-welding flipping of each side rail to ensure correct orientation; automated and precise docking and positioning of long and short side rails (long and short) and mesh panels; automated and precise welding of the docked and positioned long and short side rails and mesh panels; automated pre-stacking positioning of finished shelf panels; and automated stacking of finished shelf panels. This system is suitable not only for long and short side rails and mesh panels of different lengths but also for mesh frames of different shapes. Shelf stacking achieves high versatility, and the entire series of operations can be performed without manual intervention, eliminating the possibility of worker accidents. It boasts advantages such as high material feeding and conveying efficiency, high material feeding and conveying accuracy, high material sorting efficiency, high material sorting accuracy, high docking positioning efficiency, high docking positioning accuracy, high welding efficiency, high welding accuracy, high yield rate, high finished product stacking efficiency, good finished product stacking effect, and high production safety. It effectively solves the problems of traditional manual placement of long side rails, short side rails, and mesh panels onto corresponding clamping fixtures, which easily leads to deviations, resulting in poor welding effects, low work efficiency, poor versatility, high labor intensity for workers, and high labor costs for enterprises. Furthermore, it addresses the current lack of fully automated equipment capable of completing the entire shelf production process on the market.
