Description

Technical Field

[0001] The invention relates to the field of welding workstations, and in particular to a storage rack layer welding workstation. Background Art

[0002] The storage rack shelves are welded together from a mesh panel, two long side rails, two short side rails, and four tapered sleeves. Before the long and short side rails are welded to the mesh panels, they need to be loaded and docked. Traditionally, the long and short side rails and mesh panels are manually positioned by placing them on corresponding clamping jigs of different specifications, securing them, and then welding them using a corresponding welding machine. This method of operation results in low welding efficiency, high clamping jig costs, and poor versatility. Furthermore, the placement of the long and short side rails and mesh panels on the corresponding clamping jigs is prone to deviation, resulting in poor docking positioning accuracy, low subsequent welding precision, poor welding results, low yield rate, and high costs. Furthermore, placing the long and short side rails and mesh panels at the welding station and unloading the finished products are generally done manually, which is prone to labor safety accidents and is not conducive to the development of industrial automation. There is currently no equipment on the market that can automatically produce laminates of different shapes.

A guide sleeve 4460 slides on the first guide rod 440 to limit the position, and two second locking rings 4463 respectively limit the sliding of the second guide sleeve 4462 on the second guide rod 441. The first linear rod guide rail 4465 is obliquely installed on the upper inclined surface of the linear rod guide rail mounting tube 4464, and the second linear rod guide rail 4466 is horizontally installed on the top of the linear rod guide rail mounting tube 4464.

[0054] By adopting the above-mentioned 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, so as to realize adaptive adjustment of the loading of long side bars of different lengths, thereby meeting the loading and conveying requirements of long side bars of different lengths. The long side bars are placed on the second linear rod guide 4466 of the first linear rod guide rail positioning assembly 446 and the second linear rod guide rail positioning assembly 447 and the second wave rod guide 4489 of the wave rod guide rail positioning and adjustment assembly 448 for material preparation. When the long side bars are pushed onto the first linear rod guide 4465 of the first linear rod guide rail positioning assembly 446 and the second linear rod guide rail positioning assembly 447 and the first wave rod guide 4487 of the wave rod guide rail positioning and adjustment assembly 448, the long side bars are positioned and fixed on the first linear rod guide rail positioning assembly 446 and the second linear rod guide rail positioning assembly 447 under the action of their own gravity. The first linear rod guide rail 4465 of the linear rod guide rail positioning assembly 447 and the first wavy rod guide rail 4487 of the wavy rod guide rail positioning and adjustment assembly 448 slide and transmit for loading. The first upper guide plate positioning assembly 444 and the second upper guide plate positioning assembly 445 limit the side end and the top of the linear rod of the long side rail. The wavy rod guide rail positioning and adjustment assembly 448 supports and conducts the wavy rod of the long side rail, ensuring that the long side rail is loaded and transmitted in a flat and orderly manner. The side rail dividing assembly 4402 blocks the front long side rail for long side rail dividing and preparing materials. The side rail blocking assembly 44 01 blocks the second long side fence in front, the side fence material dividing assembly 4402 releases the long side fence in front and then resets, the two side fence feeding blocking assemblies 4403 block the long side fence in front to prepare the material before pushing the long side fence, the side fence pushing assembly 4404 pushes the long side fence in front to the side fence conveying mechanism 45 to realize the pushing of the long side fence, and at the same time, when the third photoelectric proximity switch 4444 in the first upper guide plate positioning assembly 444 senses that there is no long side fence between the side fence material dividing assembly 4402 and the side fence blocking assembly 4401, the side fence blocking assembly 4401 releases the long side fence it blocked. After the long side fence is completed, it resets to block the next long side fence. When the third photoelectric proximity switch 4444 senses the lack of a long side fence, it reminds the worker to place the long side fence for loading and preparing the long side fence, realizing fully automatic and orderly loading, fully automatic material separation and fully automatic pushing of the long side fence, and has the advantages of high loading efficiency, smooth loading, accurate material separation, high material separation efficiency, good material separation effect and high degree of automation in material separation and pushing. It solves the problems of low loading efficiency, low material separation efficiency, low material separation accuracy, low degree of automated operation, high labor intensity for workers and high labor costs for enterprises due to traditional manual loading of long side fences.

[0055] Reference Figure 6 and Figure 7As shown, the wave bar guide rail positioning 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 hand-rock ball screw 4485, at least one first guide column 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, and the wave bar The guide rail positioning tube 4484 is obliquely installed on the first guide rod 440 and the second guide rod 441 through the third guide sleeve 4480 and the fourth guide sleeve 4482 respectively. The two third locking rings 4481 are installed on the first guide rod 440 and are respectively located on both sides of the third guide sleeve 4480. The two fourth locking rings 4483 are installed on the second guide rod 441 and are respectively located on both sides of the fourth guide sleeve 4482. The first wave rod mounting plate 4488 is obliquely installed on the upper inclined surface of the wave rod guide rail positioning tube 4484. The second wave rod mounting plate 4488 is obliquely installed on the upper inclined surface of the wave rod guide rail positioning tube 4484. The mounting plate 44891 is horizontally mounted on the top of the wave bar guide rail positioning tube 4484, the first wave bar mounting plate 4488 is connected to the second wave bar mounting plate 44891, at least one first wave bar guide rail 4487 is obliquely mounted on the first wave bar mounting plate 4488, at least one second wave bar guide rail 4489 is horizontally mounted on the second wave bar mounting plate 44891, at least one first wave bar guide rail 4487 is docked with at least one second wave bar guide rail 4489; the first wave bar The mounting plate 4488 is lifted and slidably installed on the wave rod guide rail positioning tube 4484 through at least one first guide column and guide sleeve assembly 4486, and at least one hand-rock ball screw 4485 is installed on the wave rod guide rail positioning tube 4484, and the screw of the hand-rock ball screw 4485 is rotatably connected to the first wave rod mounting plate 4488. Rotating the hand-rock ball screw 4485 drives the first wave rod mounting plate 4488 to move up and down on the first guide column and guide sleeve assembly 4486 relative to the wave rod guide rail positioning tube 4484.

[0056] By adopting the above technical solution, the long side bar 44892 is placed on the second wave bar guide rail 4489 for long side bar preparation. When the long side bar 44892 is pushed onto the first wave bar guide rail 4487, the long side bar 44892 slides on the first wave bar guide rail 4487 under the action of its gravity to carry out long side bar loading. The first wave bar mounting plate 4488 is driven to rise and fall on the first guide column and guide sleeve assembly 4486 by the hand-rock ball screw 4485. By adjusting the height of the first wave bar guide rail 4487 and the second wave bar guide rail 4489, the long side bar 4489 is loaded. The height difference between the first wave rod guide rail 4487 and the first linear rod guide rail 4465 is the same as the height difference between the bottom of the linear rod 44893 in the long side rail 44892 and the bottom of the wave crest of the wave rod 44894. This avoids the long side rail 44892 from being deformed during free transportation due to the action of its own gravity caused by the first wave rod guide rail 4487 or the first linear rod guide rail 4465 being suspended. This ensures stable loading and transportation of the long side rails, smooth and efficient transportation, and is suitable for smooth transportation of long side rails of different specifications, so as to achieve its strong versatility.

The second linear rod end limit 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.

[0058] By adopting the above-mentioned 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 second straight rod end limit plate 4442 limits the end of the straight rod of the long side rail, thereby preventing the long side rail from being dislocated and offset during free transmission. At the same time, the first wavy rod guide rail 4487 and the first straight rod guide rail 4465 are parallel to each other, guiding the free transmission of the long side rail, ensuring that the long side rail is always perpendicular to the first wavy rod guide rail 4487 and the first straight rod guide rail 4465 during free transmission, thereby preventing the long side rail from being skewed and dislocated and derailed during free transmission. Each side rail realizes automatic and orderly free transmission, and has the advantages of high transmission efficiency and high transmission accuracy.

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 rails and the short side rails are automatically and accurately docked and positioned before welding. After the docking and positioning, the long side rails and the short side rails are The welding effect between the fence and the mesh is good, and the yield rate is high. It is suitable for the automated docking and positioning of long side fences and short side fences of different lengths with the mesh, and has strong versatility. It reduces the high cost of using clamping fixtures, reduces the labor intensity of workers, and reduces the labor costs of enterprises.

[0081] By adopting the above technical solution, when the long sidebar is transferred to the sidebar carrier rod 133 by the sidebar conveying mechanism 45, the fixed block translation drive device 136 drives the sidebar carrier rod 133 via the connecting plate 137 to limit the long sidebar on the sidebar carrier rod 133. When the sidebar conveying mechanism 45 releases the long sidebar, the fixed block translation drive device 136 drives the sidebar carrier rod 133 via the connecting plate 137 to further press the long sidebar against the side of the lower welding head 131, thereby preventing the sidebar conveying mechanism 45 from clamping the long sidebar and interfering with its positioning on the sidebar carrier rod 133. This not only realizes the automated docking and positioning of the long sidebar and the screen, but also ensures high docking and positioning accuracy and high efficiency of the long sidebar and the screen, thus solving the problem of traditional manual docking of the long and short sidebars with the screen.

[0085] By adopting the above-mentioned technical solution, the layer plate stacking mechanism 9 is used to stack the layers for storage, and the stacking limit posts 91 are installed on the edge of the stacking base 90 through the stacking adjustment seat 92.

Two opposing photoelectric sensors 94 automatically detect whether the stacked layers on the stacking base 90 exceed the height of the detection position. When the two opposing photoelectric sensors 94 detect that there are layers, they stop stacking the layers on the stacking base 90. This realizes automatic stacking of the layers and automatic detection of the stacking height of the layers, avoids the layers from being stacked too high, and ensures that the layer height of the stacked layers can be kept consistent, so that it has the advantages of high stacking efficiency and good stacking effect, and solves the trouble of traditional manual stacking of the layers and the need to manually count the number of stacked layers.
