Description

Technical Field

[0001] The invention relates to the technical field of steel structure welding, and in particular to a steel structure submerged arc welding robot and a use method thereof. Background Art

[0002] With the rapid development of prefabricated steel structures, steel box columns are increasingly widely used. The welding method of box columns needs to be more automated and intelligent to meet the requirements of high efficiency and high quality. The steel structure submerged arc welding robot is an advanced welding equipment that integrates steel structure welding requirements, submerged arc welding technology and robot automation technology. It can achieve efficient, precise and automated welding operations during the manufacturing and processing of steel structures.

[0003] During the submerged arc welding process, a large amount of flux is not melted after welding, but scattered around the welding area. Recycling this unmelted flux can significantly reduce the use of new flux, thereby reducing production costs. The main method for recycling submerged arc welding flux is to use an automatic recycling device, which collects the unmelted flux by suction.

[0004] However, in actual application, the recycled welding is usually mixed with some tiny welding slag and dust, so it needs to be screened after collection. However, the current recovery device and screening device are independent of each other. Therefore, the operator needs to transfer the flux collected by the recovery device to the screening device for screening, which is more cumbersome and affects the efficiency of the welding after recovery.

DETAILED DESCRIPTION

[0044] The technical scheme of the present invention will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example 1

[0046] See also Figure 1-Figure 3 As shown, the present invention is a steel structure submerged arc welding robot, comprising a base 101, a robot arm 2 is fixedly arranged on the base 101, and a submerged arc welding end 201 is provided at the end of the robot arm 2; specifically, the robot arm 2 and the submerged arc welding end 201 of this embodiment are prior art, and their specific structures are not limited, and are used for submerged arc welding of steel structures;

[0047] Among them, a welding wire conveying device 203 is fixedly arranged on one side of the base 101 for conveying welding wire to the submerged arc welding end 201. The welding wire conveying device 203 of this embodiment is also not related to the prior art, and its model and specific structure are not limited.

[0048] In this embodiment, please refer to Figure 4-Figure 6, the submerged arc welding end 201 is fixed on the end positioning frame 202 of the robot arm 2, and the recovery end 3 is fixedly arranged on one side of the positioning frame 202, and the recovery end 3 is connected to the exhaust pipe 301. A recovery box 302 is provided on the other side of the base 101, and the other end of the exhaust pipe 301 is connected to the recovery box 302, and a negative pressure fan 702 is provided in the recovery box 302; specifically, during the submerged arc welding process, as the submerged arc welding end 201 moves along the weld, the recovery end 3 can be synchronously driven to move through the positioning frame 202. During the movement, the negative pressure fan 702 is started, and the negative pressure fan 702 generates negative pressure in the recovery box 302, so as to draw the unused welding machine in the weld into the recovery box 302 through the recovery end 3 and the exhaust pipe 301;

[0049] As a further solution of this embodiment, a screening module and an adsorption module are also arranged in the recovery box 302. The screening module is used to separate the recovered flux from impurities, and the adsorption module is used to adsorb the separated impurities. It can be explained that, after the welding machine is absorbed into the recovery box 302 by the negative pressure fan 702, the welding machine and impurities are first separated by the screening module arranged in the recovery box 302. After the separation is completed, the impurities are further adsorbed by the adsorption module, and the purified air is finally discharged from the recovery box 302. In this embodiment, by sequentially arranging the screening module and the adsorption module in the recovery box 302, the recovered flux and impurities can be directly screened and separated without the need for secondary transfer, thereby effectively improving the flux recovery efficiency.

[0050] Example 2

[0051] Based on Example 1, please refer to Figure 5-Figure 8, through slots 303 are respectively provided on the two side walls of the recovery box body 302, and the through slots 303 on both sides are symmetrically arranged, and the screening module includes a first screening box 7 and a second screening box 701 slidably connected to the through slots 303, and the first screening box 7 and the second screening box 701 are connected to a driving module that drives them to slide along the through slots 303, wherein the bottoms of the first screening box 7 and the second screening box 701 are evenly provided with a plurality of groups of sieve holes 705 for screening flux; it can be explained that, in the present embodiment, the box walls of the first screening box 7 and the second screening box 701 are slidably fitted with the slot walls of the through slots 303, and the horizontal length of the screening box is the same as the horizontal length of the recovery box body 302, therefore, after any group of screening boxes are embedded in the through slots 303 on both sides, the two side walls of the screening box can achieve sealing treatment of the through slots 303; specifically In the initial state, one group of screening boxes is in a state of being embedded in the through slots 303 on both sides. After the negative pressure fan 702 adsorbs the flux to the recovery box 302, the flux can be filtered through the sieve holes 705 of the group of screening boxes, so that dust and impurities with smaller particle sizes can pass through the sieve holes 705, thereby achieving a separation effect. When a certain amount of flux is stored in the group of screening boxes, in order to avoid excessive accumulation of flux and affecting the normal screening of the sieve holes 705, this embodiment can extract this group of screening boxes from the through slots 303 through the driving module, so that the other group of screening boxes is embedded in the through slots 303 on both sides for screening again. Therefore, this embodiment uses two groups of screening boxes for alternating screening, which can not only improve the screening efficiency, but also improve the screening effect and avoid the presence of flux clogging the sieve holes 705.

[0052] In this embodiment, the adsorption module includes an impurity adsorption net 703 slidably embedded in the recovery box 302, wherein a slide groove is provided on the box wall of the recovery box 302 for embedding the impurity adsorption net 703, and the impurity adsorption net 703 is arranged between the screening box and the negative pressure fan 702; it can be explained that the impurities passing through the sieve holes 705 can be adsorbed by the impurity adsorption net 703, thereby achieving a purification effect; correspondingly, the impurity adsorption net 703 of this embodiment can be pulled out through the slide groove after being used for a period of time for cleaning or replacement, so as to avoid long-term use affecting its adsorption effect.

[0053] See also Figure 6-Figure 8A connecting block 704 is arranged between the first screening box 7 and the second screening box 701, and the connecting block 704 is slidably fitted with the groove wall of the through groove 303. The first screening box 7 and the second screening box 701 are rotatably connected with the connecting block 704, wherein a rotating module is also arranged on the recovery box body 302, and the rotating module is used to drive the screening box to rotate; it can be explained that when any group of screening boxes is pulled out from the through groove 303, as it completely moves to the outside of the recovery box body 302, this embodiment can drive the group of screening boxes to rotate 180 degrees through the rotating module, so that the flux located in the screening box can be discharged, which is convenient for collection.

[0054] Specifically, the first screening box 7 and the second screening box 701 are fixed to the support shaft 706 at one end away from the connecting block 704, and the rotating module includes a first gear 707 fixed to the end of the support shaft 706, the first gear 707 is meshed with the first rack 708, and the first rack 708 is connected to a translation mechanism that drives it to reciprocate along the side of the screening box; it can be explained that when the screening box is pulled out of the recovery box 302, the first rack 708 is driven to move by the translation mechanism, the first rack 708 is meshed with the first gear 707 to drive the support shaft 706 and the screening box to rotate to discharge the flux in the screening box. After the discharge is completed, the translation mechanism can drive the first rack 708 to reset, so as to drive the screening box to reset.

[0055] In this embodiment, please refer to Figure 3 , Figure 5-Figure 7 The translation mechanism includes a guide rod 710 fixedly arranged at the end of the first rack 708, the guide rod 710 is slidably inserted in the support 713, one side of the support 713 is fixed to the positioning plate 709, the support shaft 706 is rotatably connected to the positioning plate 709, and a telescopic spring 711 is provided on the guide rod 710, one end of the telescopic spring 711 is fixed to the support 713, and the other end is fixed to the end of the first rack 708, and the guide wheel 712 is rotatably arranged at the end of the guide rod 710 away from the first rack 708; wherein, the first linear guide plate 304 is fixedly arranged on both sides of the recovery box 302, and the other end of the first linear guide plate 304 is fixed to the inclined guide plate 305, and the inclined guide plate 305 is inclined toward the side close to the screening box. The ends of the inclined guide plates 305 are fixed to the second linear guide plates 306. It can be explained that when the screening box is in a state of being embedded in the through grooves 303 on both sides, the guide wheel 712 at its end rolls and abuts against the first linear guide plates 304. As the driving module drives the screening box to move toward the outside of the recovery box body 302, the guide wheel 712 abuts against the inclined guide plates 305. Under the limiting action of the inclined guide plates 305, the first rack 708 can be driven to translate through the guide rod 710, and the telescopic spring 711 stretches and generates elastic force, thereby driving the first gear 707 and the screening box to rotate. Correspondingly, as the screening box moves toward the through grooves 303, the telescopic spring 711 can drive each component to reset under the action of the elastic force.

[0056] See also Figure 4 as well as Figure 6-Figure 7 The driving module includes a driving mechanism 5 fixed to the outside of the recovery box 302, the driving end of the driving mechanism 5 is fixed to the driving frame 501, and the end of the driving frame 501 is fixed to the positioning plate 709; it can be explained that when driving the screening box to translate, the driving mechanism 5 can drive the screening box to move through the driving frame 501 and the positioning plate 709.

[0057] In addition, the driving mechanism of this embodiment can adopt a synchronous belt mechanism or a screw and nut transmission mechanism to achieve driving the driving frame 501 to translate, and its specific structure is not limited.

[0058] As a further solution of this embodiment, please refer to Figure 5 as well as Figure 8-Figure 10 When the screening box is flipped 180 degrees, part of the flux is stuck in the sieve holes 705 and cannot fall under the action of its own gravity. In this embodiment, the first wind hood 6 and the second wind hood 603 are respectively arranged on both sides of the recovery box 302. The first wind hood 6 corresponds to the position when the first screening box 7 is pulled out, and the second wind hood 603 corresponds to the position when the second screening box 701 is pulled out. The first wind hood 6 and the second wind hood 603 are respectively connected to the air supply mechanism; it can be explained that when the screening box is flipped 180 degrees, the present embodiment can supply air to the wind hood above it through the air supply mechanism. Under the action of the wind, the flux stuck in the sieve holes 705 can be blown off. The present embodiment does not require the use of a vibration motor or manual cleaning, and is more efficient.

[0059] Specifically, the air supply mechanism includes a first air duct 601 connected to the first air hood 6, and also includes a second air duct 602 connected to the second air hood 603. An air outlet duct 8 is provided at the bottom of the recovery box 302. The end of the air outlet duct 8 away from the recovery box 302 is connected to the air cylinder 801. The air cylinder 801 and the air outlet duct 8 are arranged vertically. The first air duct 601 and the second air duct 602 are connected to the air cylinder 801 at one end away from the air hood, respectively. A sealing roller 807 is rotatably arranged in the air cylinder 801. The roller wall of the sealing roller 807 is vertically provided with a first air duct 806 and a second air duct 805. The first air duct 806 is connected to the second air duct 805, and the sealing roller 807 is connected to the rotating mechanism. It can be explained that when the first screening box 7 is drawn out of the through slot 303, the first air duct 806 of the sealing roller 807 is adjusted by the rotating mechanism to communicate with the first air duct 601 (see Fig. 9), the second air duct 805 is connected to the air outlet duct 8, and the negative pressure fan 702 can transport the purified air to the first wind cover 6 through the air outlet duct 8, the second air duct 805, the first air duct 806 and the first air duct 601, and finally blow it to the first screening box 7; accordingly, when the second screening box 701 is drawn out of the through slot 303, the rotating mechanism adjusts the sealing roller 807 to rotate 90 degrees, so that the first air duct 806 is connected to the air outlet duct 8, and the second air duct 805 is connected to the first air duct 601 (see Fig.10 ), thereby achieving the effect of blowing air to the second screening box 701. This embodiment does not need to use other fans for air supply operation, and can effectively utilize the tail wind blown by the negative pressure fan 702. By adjusting only one group of wind hoods for exhaust, the wind force is greater, which is convenient for discharging the flux.

[0060] In addition, see Figure 7-Figure 8 The rotating mechanism includes a support rod 802 on one side of the sealing roller 807, the support rod 802 extends to the outside of the wind tube 801, and the second gear 803 is fixedly arranged at the end of the support rod 802, wherein the driving end of the driving mechanism 5 is also fixedly arranged with a moving frame 502, and the bottom of the moving frame 502 is fixedly arranged with a second rack 804 for meshing with the second gear 803; it can be explained that as the driving mechanism 5 drives the screening box to translate, the second rack 804 can be synchronously driven to move by the moving frame 502, and the second rack 804 drives the support rod 802 to rotate by meshing with the second gear 803 during the movement, thereby driving the sealing roller 807 to rotate. This embodiment does not need to use other servo drive components to adjust the rotation of the sealing roller 807, which not only saves costs, but also has higher stability and synchronization.

[0061] It should also be noted that collecting boxes 4 are arranged on both sides of the recovery box body 302, and a feed box 401 is fixedly arranged on the collecting box 4. The top opening end of the feed box 401 is symmetrically and inclinedly arranged with a feed plate 402, and a feed port 403 is formed between the two groups of feed plates 402; it can be explained that the flux discharged from the screening box can be discharged to the collecting box 4 through the feed port 403 for collection, so as to facilitate recycling.

[0062] The base 101 is slidably arranged on the track 1, and a driving member for driving the base 101 to slide horizontally is provided on the track 1, so that the submerged arc welding end 201 can be adjusted to move along the weld.

[0063] A method for using a steel structure submerged arc welding robot comprises the following steps:

[0064] S1. After the steel structure is assembled, fill the welding flux along the welding seam;

[0065] S2, the driving member drives the base 101 to slide along the track 1, and the base 101 drives the robot arm 2 and the submerged arc welding end 201 to move along the weld to perform submerged arc welding on the weld;

[0066] S3, during the welding process, the negative pressure fan 702 is started, and the negative pressure fan 702 generates negative pressure in the recovery box 302, so as to draw the unused welding air in the weld into the recovery box 302 through the recovery terminal 3 and the exhaust pipe 301;

[0067] S4, separating the welder and impurities through a screening module arranged in the recovery box 302;

[0068] S5. After separation is completed, the impurities are further adsorbed by the adsorption module, and the purified air is finally discharged from the recovery box 302.
