Description

Technical Field

[0001] This invention relates to the field of profile production equipment technology, and in particular to an automatic assembly and welding production line for walkway panels. Background Technology

[0002] Walkway panels are a common ground structure used in construction scaffolding, providing safe walking space for workers. A walkway panel typically consists of several parts, including a base plate, side plates for reinforcing and sealing the ends of the base plate, and reinforcing ribs to enhance the compressive strength of the base plate. During production, welding is required to weld the base plate, side plates, and reinforcing ribs separately. Existing production lines typically use walkway panel welding equipment, which includes a conveyor line and welding equipment. The base plate, side plates, and reinforcing ribs are transported to the welding equipment via the conveyor line, where workers assemble them. The welding equipment then welds the individual joints. This assembly process is inefficient and cannot meet the requirements of high-efficiency production. Furthermore, after assembly, the base plate, side plates, or reinforcing ribs are prone to positional shifts on the moving upper roller conveyor, affecting the weld joint positions, reducing weld quality, and easily leading to rework. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an automatic assembly and welding production line for walkway panels, which can automatically perform pre-assembly and pre-welding before welding, thereby improving production efficiency, and can prevent the bottom plate, side plate or reinforcing rib from shifting during movement after pre-assembly and pre-welding.

[0017] Implementing this invention has the following beneficial effects:

[0018] This invention relates to an automated walkway panel assembly and welding production line, comprising a conveyor line, pre-assembly equipment, feeding and discharging equipment, and welding equipment. Before welding the walkway panel, the pre-assembly positioning component of the pre-assembly equipment positions and pre-installs the base plate, side plates, and reinforcing ribs. Then, the pre-assembly welding component pre-welds the base plate, side plates, and reinforcing ribs located on the pre-assembly workbench. Since the pre-assembly workbench is a stationary plane, the base plate, side plates, and reinforcing ribs are less prone to positional shifts. Therefore, during pre-welding, misalignment of weld points can be minimized. Furthermore, the pre-assembled and pre-welded walkway panel, after being placed on the upper roller conveyor, can be transported to the welding equipment, where the welding mechanism performs additional welding on each weld point to achieve higher connection strength. Therefore, this invention's automated walkway panel assembly and welding production line improves production efficiency and, after pre-assembly and pre-welding, prevents shifting of the base plate, side plates, or reinforcing ribs during movement, thus improving welding quality.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0028] See Figures 1-4 This invention discloses an automatic assembly and welding production line for walkway slabs 5, used for assembling and welding walkway slabs 5. The production line includes a conveyor line 1, a pre-assembly device 2 arranged along the conveyor line 1, an infeed / outfeed device 3, and a welding device 4. The pre-assembly device 2 is used to pre-assemble and pre-weld the base plate 51, side plates 52, and reinforcing ribs 53 on the walkway slab 5. After fixing the base plate 51, side plates 52, and reinforcing ribs 53, the walkway slab 5 is placed on the conveyor line 1 for transport. To distinguish between the infeed and outfeed channels, the conveyor line 1 includes an upper roller conveyor 11 and a lower roller conveyor 12. The upper roller conveyor 11 is used to transport the pre-welded walkway slab 5, and the lower roller conveyor 12 is used to transport the welded walkway slab 5, enabling the discharge of the walkway slab 5. The pre-assembly device 2 is located on the side of the upper roller conveyor 11 to push the pre-welded walkway plate 5 onto the upper roller conveyor 11. The feeding and discharging device 3 is located on the side of the upper roller conveyor 11 and the lower roller conveyor 12. The welding device 4 is located on the side of the feeding and discharging device 3 to weld the walkway plate 5.

[0029] The pre-assembly equipment 2 includes a pre-assembly workbench 21, a pre-assembly positioning component 22, and a pre-assembly welding component 23. The walkway plate 5 includes a base plate 51, side plates 52, and reinforcing ribs 53. Before pre-assembly, the base plate 51 is placed on the pre-assembly workbench 21, the side plates 52 are placed at both ends of the base plate 51, and the pre-assembly positioning component 22 is located at both ends of the pre-assembly workbench 21. The pre-assembly positioning component 22 is used to fix the side plates 52 to both ends of the base plate 51. The pre-assembly welding component 23 is movably located on the side of the pre-assembly workbench 21. The pre-assembly welding component 23 can move the reinforcing ribs 53 to a preset position, and the pre-assembly welding component 23 can weld the reinforcing ribs 53 to the base plate 51, and can also weld the side plates 52 to both ends of the base plate 51. The welding method used is spot welding.

[0030] The pre-assembled walkway plate 5 is transported to the feeding / discharging device 3, which includes a welding worktable 31, a feeding and pushing component 32, a welding positioning component 33, and a flipping and discharging component 34. The welding worktable 31 is located on the side of the upper roller conveyor 11, and the feeding and pushing component 32 is located on the upper roller conveyor 11. The feeding and pushing component 32 is used to push the walkway plate 5 onto the welding worktable 31, where the walkway plate 5 is welded, thereby further reducing the impact of the upper roller conveyor 11 on the welding process. The welding positioning component 33 is located on the side of the welding worktable 31 and is used to limit and fix the walkway plate 5 before welding. The flipping and discharging component 34 is connected to the welding worktable 31, and the welding equipment 4 welds the walkway plate 5 on the welding worktable 31. After welding, the flipping and discharging component 34 can flip the welding worktable 31 so that the walkway plate 5 slides onto the lower roller conveyor 12.

[0031] In order to fully weld the walkway slab 5, the welding equipment 4 includes a welding mechanism 41, which is located above the welding workbench 31 and is used to weld the walkway slab 5.

[0032] The beneficial effects of the embodiments of the present invention are as follows:

[0033] The automatic assembly and welding production line for walkway 5 in this embodiment of the invention includes a conveyor line 1, a pre-assembly equipment 2, a feeding and discharging equipment 3, and a welding equipment 4. Before welding the walkway 5, the pre-assembly positioning component 22 of the pre-assembly equipment 2 first positions and pre-installs the base plate 51, side plate 52, and reinforcing rib 53. Then, the pre-assembly welding component 23 pre-welds the base plate 51, side plate 52, and reinforcing rib 53 located on the pre-assembly workbench 21. Since the pre-assembly workbench 21 is a stationary plane, the base plate 51, side plate 52, and reinforcing rib 53 are not prone to positional displacement. Therefore, during pre-welding, misalignment of weld points can be avoided as much as possible. Moreover, after the pre-assembled and pre-welded walkway 5 is placed on the upper roller conveyor 11, it can be transported to the welding equipment 4. The welding mechanism 41 of the welding equipment 4 then performs supplementary welding on each weld point to form a higher connection strength. Therefore, the automatic assembly and welding production line for walkway 5 of the present invention can improve production efficiency, and after pre-assembly and pre-welding, it can prevent the bottom plate 51, side plate 52 or reinforcing rib 53 from shifting during movement, thereby improving welding quality.

[0034] The pre-installed positioning assembly 22 includes a pre-installed positioning block 221 and a pre-installed extrusion mechanism 222 respectively disposed at both ends of the pre-installed workbench 21. The pre-installed extrusion mechanism 222 includes a pre-installed extrusion block 2222 and a pre-installed extrusion drive 2221. During pre-installation, the base plate 51 is placed between the pre-installed extrusion block 2222 and the pre-installed positioning block 221. The pre-installed positioning block 221 is a fixing component. The base plate 51 is first fixed at one end to the pre-installed positioning block 221, and then the entire base plate 51 is placed flat on the pre-installed workbench 21. The side plates 52 are placed at both ends of the base plate 51, that is, at the two ends where the pre-installed extrusion block 2222 and the pre-installed positioning block 221 are located. The pre-installed extrusion drive 2221 can drive the pre-installed extrusion block 2222 to move toward the pre-installed positioning block 221 to fix the side plates 52 onto the base plate 51. The pre-installed positioning block 221 can limit the side plate 52 to prevent it from moving.

[0035] To further secure the side plate 52, the pre-installed positioning assembly 22 also includes a flipping and fixing mechanism 223 disposed on the pre-installed positioning block 221 and the pre-installed pressing block 2222. The flipping and fixing mechanism 223 includes a flipping rod 2231, a pry bar 2232, and a limiting rod 2233. One end of the flipping rod 2231 is hinged to one end of the pry bar 2232, allowing the flipping rod 2231 to flip relative to the pry bar 2232. The other end of the pry bar 2232... One end is hinged to the limiting rod 2233, which is located on the upper part of the side plate 52. In use, the flipping rod 2231 can be used to drive the pry bar 2232 and pry the limiting rod 2233. The flipping rod 2231 can flip the limiting rod 2233 so that the side part of the limiting rod 2233 abuts against the inner part of the side plate 52. Therefore, the pre-installed extrusion block 2222 and the limiting rod 2233 can limit the side plate 52 from both inside and outside directions.

[0036] The base plate 51 has a recessed interior, and the reinforcing rib 53 is disposed within the recess. To fix the reinforcing rib 53, the pre-assembly equipment 2 further includes a pre-assembly frame 24. The pre-assembly workbench 21 is disposed on the pre-assembly frame 24. The pre-assembly welding assembly 23 includes a movable rack 231 disposed on the pre-assembly frame 24, a pre-assembly moving drive 232 meshing with the movable rack 231, a movable slide 233 disposed on the pre-assembly moving drive 232, a pre-assembly lifting drive 234 disposed on the movable slide 233, and a pre-assembly lifting drive 234 disposed on the pre-assembly lifting drive 234. The pre-installed positioning clamp 235 on the 4th is provided. The moving rack 231 is arranged along the length direction of the pre-installed worktable 21. When the pre-installed moving drive 232 is activated, it can drive the moving slide 233 to move along the moving rack 231, thereby bringing the pre-installed positioning clamp 235 above the position of the reinforcing rib 53. Then, the pre-installed lifting drive 234 can drive the pre-installed positioning clamp 235 to rise and fall. After the pre-installed positioning clamp 235 descends, it can clamp the reinforcing rib 53 to form a limiting effect.

[0037] The pre-assembled welding assembly 23 further includes a pre-welding seat 236 fixed to the pre-assembly positioning clamp 235, a pre-welding lifting mechanism 237 disposed on the pre-welding seat 236, and a pre-welding gun 238 disposed at the end of the pre-welding lifting mechanism 237. The pre-welding seat 236 can move with the pre-assembly positioning clamp 235. After the pre-assembly positioning clamp 235 places and positions the reinforcing rib 53, the pre-welding lifting mechanism 237 can drive the pre-welding gun 238 to descend vertically. The weld joint of the pre-welding gun 238 faces downward and is located above the reinforcing rib 53. The pre-welding gun 238 can weld the reinforcing rib 53 and the base plate 51. After the pre-welding is completed, the pre-welding lifting mechanism 237 drives the pre-welding gun 238 to rise. The pre-installed positioning clamp 235 can also be moved to both ends of the base plate 51, so that the pre-welding gun 238 is positioned above the side plate 52, and then the pre-welding gun 238 is driven to pre-weld the side plate 52.

[0038] See Figure 5The feeding and pushing assembly 32 includes a first feeding drive 321, a first feeding push plate 322 disposed at the movable end of the first feeding push drive, a feeding lifting drive 323 disposed below the upper roller conveyor 11 and located at both ends of the first feeding push plate 322, and a feeding lifting plate 324 connected to the movable end of the feeding lifting drive 323. When the walkway plate 5 moves to the position of the feeding and pushing assembly 32, the feeding lifting drive 323 can drive the feeding lifting plate 324 to lift the walkway plate 5 so that the walkway plate 5 can move laterally. Then, the first feeding drive 321 can drive the first feeding push plate 322 to push the lifted walkway plate 5 toward the side of the upper roller conveyor 11. Furthermore, the feeding and pushing assembly 32 also includes a second feeding drive 325 disposed on the first feeding push plate 322 and a second feeding push plate 326 disposed at the movable end of the second feeding drive 325. After the first feeding drive 321 drives the first feeding push plate 322 to push the walkway plate 5 to the side, the second feeding drive 325 can drive the second feeding push plate 326 to push the walkway plate 5 located on the side of the upper roller conveyor 11 towards the welding worktable 31. The first feeding drive 321 and the second feeding drive 325 can be driven simultaneously. The first feeding drive 321 is disposed below the upper roller conveyor 11, which can avoid obstructing the movement of the walkway plate 5 on the upper roller conveyor 11. At the same time, the second feeding drive 325 is located above the upper roller conveyor 11. Through reasonable height setting, it can also avoid interfering with the movement of the walkway plate 5, ensuring that the walkway plate 5 can fall completely onto the welding worktable 31.

[0039] See Figure 6 and Figure 7 The welding positioning assembly 33 includes a support frame 331 located above one side of the welding worktable 31, a downward pressing drive 332 located on the support frame 331, a downward pressing plate 333 located at the movable end of the downward pressing drive 332, a side pressing drive 334 located on the other side of the welding worktable 31, and a side pressing block 335 with one end hinged to the movable end of the side pressing drive 334. The area below the support frame 331 is a clearance space through which the walkway plate 5 can enter the welding worktable 31. The middle part of the side pressing block 335 is hinged to the housing of the side pressing drive 334. The downward pressing drive 332 can drive the downward pressing plate 333 to press down on one side of the walkway plate 5, and the side pressing drive 334 can drive the side pressing block 335 to press down on the other side of the walkway plate 5, thereby fixing the walkway plate 5 from both sides to further ensure the welding accuracy.

[0040] After the walkway plate 5 is welded, in order to move the walkway plate 5 into the lower roller conveyor 12, a fixed frame 35 is provided below the welding worktable 31. The flipping discharge assembly 34 includes a flipping drive 341. The fixed end of the flipping drive 341 is hinged to the fixed frame 35, and the flipping drive 341 can swing relative to the fixed frame 35. The movable end of the flipping drive 341 is hinged to the bottom of the welding worktable 31 near the conveyor line 1, and the flipping drive 341 can drive the movable end to extend and retract. The two ends of the bottom of the workbench 31, on the side away from the conveyor line 1, are hinged to the fixed frame 35. When the flipping drive 341 drives its movable end to retract, the welding workbench 31 will flip downward around the hinge point with the fixed frame 35. After the welding workbench 31 flips downward, under the action of gravity, the walkway plate 5 will slide along the welding workbench 31 toward the lower roller conveyor 12. Therefore, the flipping drive 341 can drive the welding workbench 31 to flip in the direction of the lower roller conveyor 12 so that the welded walkway plate 5 slides into the lower roller conveyor 12.

[0041] See Figure 8 To prevent the welding workbench 31 from tipping over during welding, the tipping and unloading assembly 34 further includes a positioning drive 342 and a positioning telescopic rod 343. The positioning drive 342 is located at both ends of the fixed frame 35 near the conveyor line 1, and the positioning telescopic rod 343 is located at the movable end of the positioning drive 342. The welding workbench 31 has positioning holes 311 at both ends. During welding, the positioning drive 342 drives the positioning telescopic rod 343 to insert into the positioning holes 311, thereby positioning the welding workbench 31 and preventing it from tipping over. After welding is completed, before the welding workbench 31 tipps over, the positioning drive 342 drives the positioning telescopic rod 343 to retract, causing the welding workbench 31 to disengage from the limit of the positioning telescopic rod 343, facilitating tipping.

[0042] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
