Description

Technical Field

[0001] This invention relates to the technical field of gantry welding, and in particular to a highly efficient automated gantry welding equipment. Background Technology

[0002] Gantry welding gets its name from its "gantry" structure—two columns support a horizontally movable beam, forming a frame similar to a "gate." The welding head (such as a welding torch) is mounted on the beam and can move in two or three dimensions along the beam (X-axis) and the columns (Y-axis), covering a large welding area. Combined with automated control, it enables precise welding of complex paths, making it particularly suitable for large workpieces.

[0003] The core of submerged arc welding is to use the heat of an electric arc to melt the base metal and filler wire. At the same time, the flux partially melts under the heat of the electric arc, forming slag and gas, which cover the surface of the molten pool, thus isolating it from the air and protecting the molten pool. Unmelted flux can be recycled and reused.

[0004] Chinese patent CN223748734U, related to gantry welding, discloses a double-arc, double-wire submerged arc welding device suitable for gantry frames. The device includes a gantry frame connector, wherein: an arc welding bracket is provided on one side of the gantry frame connector; the top of the arc welding bracket has a through hole; symmetrical wire feeding devices are provided on the top of the arc welding bracket; motors are provided on both sides of each pair of wire feeding devices; a welding torch fixing rod is mounted at the bottom of the arc welding bracket; a pair of welding torch clamps are provided on the welding torch fixing rod; a first welding torch and a second welding torch are respectively mounted on the pair of welding torch clamps. This device can achieve double-arc welding and can flexibly adjust the height and angle of the welding torches to precisely control the welding penetration. While ensuring welding efficiency and welding quality, this device can reduce human error during the welding process, significantly improve the control capability of welding penetration, ensure personnel safety, and improve the overall performance of the equipment.

[0005] The aforementioned related technologies and existing technologies of gantry welding have the following defects: In the solder recycling process of gantry welding, there will be clumps of solder in the re-pulled solder. If the recycled clumps of solder are directly discharged again, they are likely to cause blockage in the solder feeding section, affecting the solder feeding speed and making the solder distribution at the weld uneven, thus affecting the uniformity of the weld.

[0042] In summary, the present invention has the following beneficial technical effects: This invention utilizes the combined use of a solder negative pressure back-extraction unit and a multi-stage screening and crushing component. The solder negative pressure back-extraction unit draws out the used solder under negative pressure and then sends it into the multi-stage screening and crushing component. The multi-stage screening and crushing component crushes any clumps in the back-extracted solder. The solder without clumps is then sent into the solder feeding unit, ensuring that the material conveyed by the solder feeding unit is free of clumps and that solder can be conveyed stably.

[0043] This invention utilizes the cooperation between a primary screening plate and multiple staggered partition plates. As the primary screening plate vibrates, the solder collected on its upper side gradually slides down the inclined upper side of the screening plate. Simultaneously, the staggered partition plates restrict the solder's movement trajectory on the upper side of the primary screening plate to a reciprocating, bending path, increasing the solder's travel distance. Of the collected solder, un-clumped solder falls to the lower side of the primary screening plate, while clumped solder is blocked within the primary screening plate. The clumped solder then falls onto the upper side of the secondary screening disc for crushing, preventing the un-clumped solder from forming dusty solder, which would be inconvenient for later use.

[0044] In this invention, the feeding process involves the coordinated use of an inner ring disc, a power rotating disc, baffles, and a feeding trough. Multiple baffles create multiple separate spaces between the inner ring disc and the power rotating disc, separating the feeding trough from the discharge end of the screening return pipe. This prevents airflow from entering the solder feeding cylinder and affecting the feeding speed. As the baffles rotate with the power rotating disc, the solder that falls between adjacent baffles is moved to the feeding trough position and falls into the solder feeding cylinder.

[0045] This invention utilizes the cooperation between the material gathering cylinder, the powder sieve disc, and the ribs. After the solder screened by the primary screening plate and the solder screened by the secondary screening disc are crushed, the solder falls onto the material gathering cylinder. The falling solder falls from the central axis of the conical material gathering cylinder to the center of the upper side of the powder sieve disc. The dusty solder in the solder falls to the lower side of the screening disc under the airflow and enters the powder storage tank. The airflow is discharged from the upper end of the powder storage tank, reducing the amount of dusty solder entering the solder discharge cylinder. This prevents the dusty solder from easily entering the air after being discharged from the discharge end pipe, increasing the amount of dust in the working environment and causing pollution to the health of the workers. At the same time, the dusty solder is inconvenient to recycle and process again. Attached Figure Description

[0048] The following is in conjunction with the appendix Figures 1-9 The present invention will be described in further detail below.

[0049] This invention discloses a highly efficient automated gantry welding device. For example... Figures 1-9As shown, it includes a gantry drive body 1, a welding processing unit 2, a solder feeding unit 3, a solder negative pressure back-pulling unit 4, and a multi-stage screening and crushing component 5.

[0050] In this invention, the gantry drive body 1 includes a horizontal drive part and a vertical drive part, which can control the connected structure to move in a vertical plane. At the same time, the gantry drive body 1 can move relative to the placed material. Two material support frames are placed on the inner side of the gantry shape of the gantry drive body 1 to support the material to be welded.

[0051] The upper ends of the welding processing unit 2, the solder unloading unit 3, and the solder negative pressure return unit 4 are all installed on the horizontal drive end of the gantry drive body 1. The discharge end of the solder unloading unit 3 is coaxially arranged with the welding end of the welding processing unit 2. The welding end of the welding processing unit 2 is located inside the discharge end of the solder unloading unit 3. The solder negative pressure return unit 4 is located on one side of the solder unloading unit 3. The negative pressure extraction end of the solder negative pressure return unit 4 is located on the side of the discharge end of the solder unloading unit 3.

[0052] In this embodiment, the solder feeding unit 3 adds solder to the welding point of the solder feeding unit 3, the welding end of the solder feeding unit 3 can perform submerged arc welding on the material, and the solder negative pressure recovery unit 4 can recover the residual solder after welding under negative pressure.

[0053] The feed end of the multi-stage screening and crushing component 5 is connected to the discharge end of the solder negative pressure back-extraction unit 4. The multi-stage screening and crushing component 5 can screen the solder powder entering the inner side and crush the agglomerated solder powder blocks. The discharge end of the multi-stage screening and crushing component 5 is connected to the solder feeding unit 3. The multi-stage screening and crushing component 5 can send the crushed and screened small particles of solder powder into the solder feeding unit 3.

[0054] Furthermore, in this embodiment, the solder negative pressure back-pulverization unit 4 fills the recovered solder into the multi-stage screening and crushing component 5. The multi-stage screening and crushing component 5 crushes the clumped solder that enters the interior, and then adds the crushed solder that no longer clumps into the solder feeding unit 3. This prevents the solder being conveyed downward by the solder feeding unit 3 from clumping, which would cause the material to move downwards unevenly and affect the uniformity of the solder added to the welding point of the material.

[0055] In this embodiment, as Figures 1-9 As shown, the solder unloading unit 3 includes a solder unloading cylinder 31, a return material transfer assembly 32, an unloading hose 33, and an unloading end pipe 34.

[0056] The solder feeding cylinder 31 is installed at the horizontal drive end of the gantry drive body 1, the return material transfer component 32 is installed at the upper end of the solder feeding cylinder 31, and the discharge end of the multi-stage screening and crushing component 5 is connected to the return material transfer component 32.

[0057] The upper end of the feeding hose 33 is installed at the discharge end of the welding material feeding cylinder 31, the welding end of the welding processing unit 2 is installed inside the feeding end pipe 34, the welding end of the welding processing unit 2 and the feeding end pipe 34 are installed at the vertical driving end of the gantry drive body 1, and the upper end of the feeding end pipe 34 is connected to the lower end of the feeding hose 33.

[0058] Preferably, the solder feeding cylinder 31 can power the downward conveying of solder, and the vertical drive end of the gantry drive body 1 can drive the feeding end pipe 34 and the welding end of the welding processing unit 2 to move up and down. The feeding hose 33 bends synchronously with the movement of the feeding end pipe 34.

[0059] Furthermore, in this embodiment, the solder negative pressure retraction unit 4 includes a dynamic negative pressure retraction structure 41, a negative pressure retraction hose 42, and a negative pressure retraction end tube 43.

[0060] The power negative pressure return structure 41 is installed at the horizontal drive end of the gantry drive body 1. The negative pressure return hose 42 is connected to the negative pressure return end of the power negative pressure return structure 41. The negative pressure return end pipe 43 is connected to the discharge end pipe 34. The upper end of the negative pressure return end pipe 43 is connected to the negative pressure return hose 42.

[0061] The power negative pressure return structure 41 is equipped with a negative pressure machine, which can apply negative pressure to the negative pressure return hose 42 and the negative pressure return end pipe 43, and draw the solder on the lower side of the negative pressure return end pipe 43 upward under negative pressure.

[0062] In this invention, the negative pressure return hose 42 and the discharge hose 33 are made of a uniform deformable material, such as rubber, and the inside of the pipes is provided with braided metal mesh to ensure that they can deform without expanding or flattening due to changes in internal air pressure.

[0063] In this embodiment, as Figures 1-9 As shown, the multi-stage screening and crushing assembly 5 includes a primary screening box 51, a screening plate assembly 52, a secondary crushing cylinder 53, a secondary screening disc 54, an impact rod 55, a power drive assembly 56, and a screening discharge assembly 57.

[0064] The discharge end of the power negative pressure back-extraction structure 41 is installed through the upper surface of the primary screening box 51. The screening plate assembly 52 is set inside the primary screening box 51 and is inclined. The end of the primary screening box 51 away from the power negative pressure back-extraction structure 41 is inserted through the circumferential side of the secondary crushing cylinder 53. The end of the screening plate assembly 52 near the secondary crushing cylinder 53 is located on the lower side of the other end of the screening plate assembly 52. ​​The secondary screening disc 54 is located on the lower side of the screening plate assembly 52 and is coaxially inserted into the inner side of the secondary crushing cylinder 53.

[0065] The impact rod 55 is located inside the secondary crushing cylinder 53 and on the upper side of the secondary screening disc 54. The power drive assembly 56 drives the screening plate assembly 52 to sway back and forth in the primary screening box 51. The power drive assembly 56 drives the impact rod 55 to rotate around the axis of the secondary screening disc 54.

[0066] The screening and discharge assembly 57 is installed on the lower side of the secondary crushing cylinder 53, and the other end of the screening and discharge assembly 57 is connected to the return material conveying assembly 32.

[0067] During operation, the power negative pressure back-pull structure 41 discharges the back-pulled solder onto the upper part of the screening plate assembly 52. ​​Then, the power drive assembly 56 drives the screening plate assembly 52 to sway back and forth, screening the solder on the upper side. Unclumped solder is screened off by the screening plate assembly 52, while clumped solder is blocked on the upper side of the screening plate assembly 52 and then slides to the upper side of the secondary screening disc 54. Next, the power drive assembly 56 drives the impact rod 55 to collide and crush the clumped solder on the upper side of the secondary screening disc 54. The crushed solder falls to the lower side through the secondary screening disc 54 and converges with the unclumped solder screened off by the screening plate assembly 52. ​​Then, it enters the solder feeding cylinder 31 through the screening discharge assembly 57 and the return material transfer assembly 32, thus completing the recycling of the used solder.

[0068] Furthermore, in this embodiment, the power drive assembly 56 includes a power rotation shaft 561, a horizontal insert frame 562, and a swing plate 564.

[0069] The secondary crushing cylinder 53 is coaxially rotatably sleeved on the outer surface of the power rotating shaft 561, the impact rod 55 is installed perpendicularly to the power rotating shaft 561, and the secondary screening disc 54 is rotatably sleeved on the outside of the power rotating shaft 561.

[0070] One end of the horizontal insertion frame 562 slides through the front of the primary screening box 51. The end of the horizontal insertion frame 562 located inside the primary screening box 51 is connected to the screening plate assembly 52. ​​The end of the horizontal insertion frame 562 located outside the primary screening box 51 is equipped with a horizontal frame 563. The horizontal frame 563 is set perpendicular to the power rotation shaft 561.

[0071] One end of the swing plate 564 is equipped with a shaft 565, and the bottom surface of the other end of the swing plate 564 is fixed with an end shaft 566. The end shaft 566 is rotatably inserted into the upper surface of the preliminary screening box 51. The swing plate 564 is located on the lower side of the horizontal frame 563. The upper end of the shaft 565 is slidably inserted into the interior of the horizontal frame 563. The end shaft 566 and the power rotating shaft 561 are driven by the conveyor belt 567.

[0072] In this embodiment, a motor is installed on the outside of the secondary crushing cylinder 53 to drive the power rotating shaft 561 to rotate. The power rotating shaft 561 drives the impact rod 55 to rotate and impact the agglomerated solder. The power rotating shaft 561 drives the end shaft 566 to rotate through the conveyor belt 567. The end shaft 566 drives the insertion shaft 565 to slide in the horizontal frame 563 through the swing plate 564, causing the horizontal frame 563, the horizontal insertion frame 562 and the screening plate assembly 52 to sway back and forth, screening the solder on the upper side of the screening plate assembly 52.

[0073] Second embodiment, such as Figures 1-9 As shown, the screening plate assembly 52 includes a primary screening plate 521 and multiple partition plates 522. The partition plates 522 are installed on the upper surface of the primary screening plate 521. The primary screening plate 521 and the partition plates 522 are located inside the preliminary screening box 51. The end of the primary screening plate 521 near the secondary crushing cylinder 53 is located on the upper side of the other end of the primary screening plate 521. The upper and lower ends of the primary screening plate 521 are open. The two adjacent partition plates 522 are staggered front and back. There are gaps between the two adjacent partition plates 522 and the inner walls of the front and rear sides of the primary screening plate 521.

[0074] Multiple partition plates 522, staggered front and back, restrict the sliding path of the solder on the upper side of the primary screening plate 521 to a reciprocating bending shape, increase the sliding path of the solder on the upper side of the primary screening plate 521, increase the screening time, prevent the unagglomerated solder in the solder from not being fully separated, and prevent the unagglomerated solder from being collided again to form dusty solder.

[0075] A sliding plate 523 is attached to and parallel to the lower side of the primary screening plate 521. The sliding plate 523 is inserted into the outer surface of the secondary crushing cylinder 53. The horizontal insert frame 562 is located inside the preliminary screening box 51 and is fixed at one end to the primary screening plate 521.

[0076] The screen holes of the primary screening plate 521 and the secondary screening disc 54 are the same size. The upper and lower spaces of the sliding plate 523 are connected to the upper and lower spaces of the secondary screening disc 54, respectively. The sliding plate 523 guides the agglomerated material blocked by the primary screening plate 521 to the upper side of the secondary screening disc 54.

[0077] The screening discharge assembly 57 includes a bottom cylinder 571 and a screening return pipe 572.

[0078] The upper end of the bottom cylinder 571 is located below the primary screening box 51. The upper end of the bottom cylinder 571 is fixedly sleeved on the lower end of the secondary crushing cylinder 53. One end of the screening return pipe 572 is coaxially installed with the lower end of the bottom cylinder 571, and the other end of the screening return pipe 572 is connected to the return material transfer assembly 32.

[0079] A powder collection cylinder 573 is coaxially arranged inside the bottom cylinder 571. The outer ring side of the powder collection cylinder 573 is separated from the inner ring surface of the bottom cylinder 571. The upper end of the powder collection cylinder 573 is separated from the upper end of the secondary crushing cylinder 53. The powder collection cylinder 573 and the secondary crushing cylinder 53 are coaxially fixed.

[0080] A rotatable powder sieve disc 574 is coaxially inserted into the upper end of the powder collection cylinder 573. The upper surface of the powder sieve disc 574 is flush with the upper end of the powder collection cylinder 573, and the upper surface of the powder sieve disc 574 is fixed to the lower end of the power rotating shaft 561.

[0081] A powder discharge pipe 575 is coaxially installed at the lower end of the powder collection cylinder 573. The lower end of the powder discharge pipe 575 extends from the lower end of the bottom cylinder 571 and passes through the screening return pipe 572. The outer side of the powder discharge pipe 575 is spaced apart from the inner wall of the lower end of the bottom cylinder 571 and the inner wall of the screening return pipe 572.

[0082] A material hopper 577 is provided on the upper side of the powder screen 574. The material hopper 577 is fixedly inserted into the interior of the secondary crushing cylinder 53. The material hopper 577 is located on the lower side of the preliminary screening box 51. The material hopper 577 is funnel-shaped. The minimum inner diameter gap between the outer side of the power rotation shaft 561 and the material hopper 577 is set. Multiple evenly distributed ribs 578 are fixedly installed on the upper surface of the powder screen 574. The lower end of the material hopper 577 is coaxial with the powder screen 574. The material hopper 577 makes the solder falling from the upper side tend to move towards the axis of the powder screen 574, preventing the solder from falling directly onto the outer ring side of the powder screen 574. If the dust solder is not separated, it will be directly thrown into the bottom cylinder 571. The setting of the ribs 578 increases the effect of the powder screen 574 driving the upper solder to rotate, making it easier for the solder to follow the rotation of the powder screen 574 and be thrown out.

[0083] The powder discharge pipe 575 is located at one end below the screening return pipe 572 and a powder storage tank 576 is installed thereon. The upper end of the powder storage tank 576 is ventilated. The airflow that fills the secondary crushing cylinder 53 carries the dust material through the powder screen 574 and the powder discharge pipe 575 into the powder storage tank 576. The airflow is discharged from the upper end of the powder storage tank 576, which traps the dust in the powder storage tank 576 and completes the collection. The lower end of the powder storage tank 576 can be opened. After the lower end of the powder storage tank 576 is opened, the collected dust solder inside can be taken out and reprocessed into granular solder.

[0084] During negative pressure backflow, the solder drawn back by the airflow first enters the preliminary screening box 51 for preliminary screening. Then, the impact rod 55 impacts and breaks up the solder that has clumped on the upper side of the secondary screening disc 54. The broken solder then merges with the unclumped solder that has fallen from the primary screening plate 521 through the secondary screening disc 54 and falls onto the upper side of the powder screening disc 574. Meanwhile, the dust-sized solder inside the solder is driven by the airflow through the powder screening disc 574 into the powder storage tank 576, while the normal-sized solder is thrown into the inner side of the bottom cylinder 571 through the gap between the secondary crushing cylinder 53 and the powder storage tank 576 as the powder screening disc 574 rotates.

[0085] After separating the dust solder, the amount of dust solder discharged from the discharge end pipe 34 is reduced, which reduces the harm to the health of workers caused by the dust solder drifting into the air after discharge. At the same time, the large amount of drifting dust greatly increases the waste of solder and makes it inconvenient to recycle and reprocess.

[0086] In this embodiment, the return material transfer assembly 32 includes an inner cavity ring disk 321, a power rotating disk 323, and a solder replenishment cylinder 325.

[0087] The inner ring disk 321 is coaxially fixedly installed on the upper end of the solder feeding cylinder 31. The lower end of the screening return pipe 572 is installed through the upper surface of the inner ring disk 321. The upper end of the solder feeding cylinder 31 is provided with a feeding groove 322 that communicates with the interior. The feeding groove 322 and the screening return pipe 572 are located on both sides of the axis of the inner ring disk 321, respectively.

[0088] The power rotating disk 323 is coaxially mounted inside the inner cavity ring disk 321. The power rotating disk 323 rotates relative to the inner cavity ring disk 321. Multiple baffles 324 are fixed on the outer ring surface of the inner cavity ring disk 321. The other end of the baffle 324 slides in contact with the inner ring surface of the inner cavity of the inner cavity ring disk 321. A motor is installed on the outside of the inner cavity ring disk 321 to supply power to the power rotating disk 323, driving the power rotating disk 323 to rotate.

[0089] The upper end of the solder replenishing cylinder 325 can be disassembled, and solder can be added into the solder replenishing cylinder 325 after disassembly to replenish the solder lost in the solder feeding cylinder 31. The solder replenishing cylinder 325 is located on the upper side of the replenishing groove 322, so that the solder replenishing cylinder 325 can directly pass through the space between the two lower baffles 324 and the replenishing groove 322 to add the replenished solder into the solder feeding cylinder 31. The lower end of the solder replenishing cylinder 325 is installed through the upper surface of the inner cavity ring plate 321.

[0090] Multiple baffles 324 form multiple separate spaces between the inner ring disc 321 and the power rotating disc 323, separating the feeding trough 322 from the discharge end of the screening return pipe 572, preventing airflow from entering the solder feeding cylinder 31 and affecting the feeding speed, and ensuring sufficient airflow to drive the dust solder powder screen disc 574 into the powder storage tank 576. As the baffles 324 rotate with the power rotating disc 323, the solder that falls between the adjacent baffles 324 is moved to the position of the feeding trough 322 and falls into the solder feeding cylinder 31. The re-drawn solder is added back into the solder feeding cylinder 31.

[0091] The working principle is as follows: The material to be welded is placed under the gantry drive body 1. The gantry drive body 1 controls the welding processing unit 2, the solder feeding unit 3, and the solder negative pressure return unit 4 to move to the weld position of the material. The solder feeding unit 3 discharges solder to the welding position of the welding processing unit 2. The welding processing unit 2 performs submerged arc welding. The solder negative pressure return unit 4 returns the remaining solder after welding and sends the recovered solder into the multi-stage screening and crushing component 5. The multi-stage screening and crushing component 5 crushes the clumps of solder in the returned solder. The solder without clumps after processing is then sent into the solder feeding unit 3, so that there are no clumps in the solder conveyed downward by the solder feeding unit 3, ensuring the stability of the feeding.

[0092] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
