Description

Technical Field

[0001] The present invention relates to the technical field of welding robots, and particularly to an automatic welding robot for angle steel production. Background Art

[0002] In the angle steel production and processing industry, welding is a key process for connecting two angle steels into a required structural member. As shown in the traditional angle steel frame Figure 1 It includes two vertical beam angle steels and several cross beam angle steels. The two ends of the cross beam angle steel are respectively welded and fixed to the two vertical beam angle steels, and the vertical beam angle steel and the cross beam angle steel are perpendicular to each other. With this angle steel frame as the main body, combined with other specifications of angle steels or connectors, various different types of frame devices, such as shelves, can be made.

[0003] At present, most of the welding processes of angle steel frames in the industry still rely on manual operation. During actual operation, the operator needs to manually align the two angle steels to be welded first. Since the angle steel itself has a certain weight and the corners and weld positions of the angle steel need to be precisely aligned, this operation process is not only time-consuming and laborious, resulting in extremely low overall welding operation efficiency and difficult to meet the needs of large-scale production; moreover, the long-term repetitive high-intensity work makes the labor intensity of the operator extremely high, prone to fatigue, which in turn affects the stability and consistency of welding quality and increases the defective rate.

[0004] In addition, if a welding robotic arm is used to replace manual welding, although the welding efficiency and safety can be improved to a certain extent, the docking process between the two angle steels still requires manual alignment by humans, with a high degree of human dependence. And if there is a deviation in the alignment process, such as the vertical beam and the cross beam are not fully perpendicular, there may still be welding quality problems. Therefore, it is urgent to design a welding robot for angle steel production to solve the problems of high manual labor intensity and unstable quality in the prior art. For this reason, we have proposed an automatic welding robot for angle steel production to well solve the above drawbacks. Summary of the Invention

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figure 1 - Figure 10 , an automatic welding robot for angle steel production is proposed in an embodiment of the present application, which includes a base 100 and a welding manipulator 200 arranged on the base 100, and further includes a welding table 300, a vertical beam moving mechanism 400, a cross beam moving mechanism 500 and a splicing mechanism 600. Among them, the welding table 300 is fixedly installed on the base 100 through a column. The welding table 300 is in a rectangular plate structure. An installation notch 301 is opened on one side of the welding table 300, and the depth of the installation notch 301 is not less than half of the width of the welding table 300.

[0040] Furthermore, the vertical beam moving mechanism 400 includes a first linear slide 401 and a first clamp 402. The first linear slide 401 is arranged on the welding table 300, and the moving end of the first linear slide 401 is connected to the first clamp 402 through a connecting piece 403. Specifically, the connecting piece 403 is in an L-shaped plate structure. The connecting piece 403 is fixedly connected to the moving end of the first linear slide 401 through bolts, and the first clamp 402 is fixedly arranged inside the connecting piece 403. An opening for the jaws of the first clamp 402 to pass through is also opened on the connecting piece 403. The two jaws of the first clamp 402 pass through the opening and are respectively connected with first clamping pieces 404. The two first clamping pieces 404 are distributed up and down, and the width of the first clamping piece 404 is not less than the width of the angle steel.

[0041] It should be noted that the length of the first linear slide 401 is the same as the length of the welding table 300. When the first clamp 402 clamps the angle steel, the angle steel also keeps the same length as the welding table 300. At the same time, the length of the angle steel shall not exceed the length of the welding table 300.

[0042] The cross beam moving mechanism 500 is arranged in the installation notch 301. The cross beam moving mechanism 500 includes two load-bearing plates 501 arranged at intervals front and back. Second clamps 502 are movably arranged on both load-bearing plates 501. The splicing mechanism 600 is arranged between the two load-bearing plates 501, and the splicing mechanism 600 is respectively used to push the second clamps 502 on the two load-bearing plates 501 to approach or move away from the vertical beam moving mechanism 400. Among them, the second clamp 502 is used to clamp the cross beam angle steel, and the splicing mechanism 600 is used to drive the cross beam angle steel to approach the vertical beam angle steel so that the two are abutted and aligned.

[0043] Among them, both the first fixture 402 and the second fixture 502 adopt electric parallel jaws, and the angle steels clamped by the first fixture 402 and the second fixture 502 are perpendicularly distributed to each other. In addition, a baffle 302 is provided on the upper surface of the welding table 300. When the first fixture 402 clamps and fixes the angle steel, the side of the angle steel facing away from the mounting notch 301 abuts against the baffle 302. The function of the baffle 302 is to maintain the stability of the angle steel and ensure that it can always be parallel to the length direction of the welding table 300.

[0044] In some embodiments of the present application, the splicing mechanism 600 includes a seat plate 601. The seat plate 601 is fixedly connected to the welding table 300, and the upper surface of the seat plate 601 is flush with the upper surface of the welding table 300. Two carrier plates 501 are respectively rotatably connected to both sides of the seat plate 601. Specifically, a bushing 603 is provided at the end of the seat plate 601. A rotating column 604 is rotatably provided inside the bushing 603. A rotating sleeve 605 is sleeved outside the bushing 603. An arc-shaped opening 606 is formed in the side wall of the bushing 603. The central angle of the arc-shaped opening 606 is not less than 180°. A positioning column 607 is inserted into the arc-shaped opening 606. The inner and outer ends of the positioning column 607 are respectively fixedly connected to the rotating column 604 and the rotating sleeve 605. Symmetrically provided on both sides outside the rotating sleeve 605 are extension columns 611, and the two extension columns 611 are respectively fixedly connected to the two carrier plates 501.

[0045] It is worth mentioning that both the rotating column 604 and the rotating sleeve 605 are rotationally matched with the bushing 603 through ball bearings, and the outer end of the rotating column 604 does not extend outside the bushing 603; the arc-shaped opening 606 is located in the middle section of the bushing 603. A threaded hole is formed on the surface of the rotating column 604, and a through hole is formed on the rotating sleeve 605. The threaded hole and the through hole are both located at the position of the arc-shaped opening 606; in the specific installation of this embodiment, first align the through hole and the threaded hole, and then insert the positioning column 607 from the outside to the inside, so that the bottom end of the positioning column 607 is threadedly connected to the threaded hole, so that the rotating column 604 and the rotating sleeve 605 can rotate synchronously.

[0046] Furthermore, a motor seat 608 is fixedly provided at the end of the bushing 603. A servo motor 609 is installed on the motor seat 608. The output shaft of the servo motor 609 is fixedly connected to the rotating column 604; therefore, the rotation of the rotating column 604 can be controlled through the servo motor 609, that is, the rotation of the two carrier plates 501 around the bushing 603 can be controlled. Specifically, in this embodiment, the servo motor 609 is used to control the two carrier plates 501 to rotate back and forth by 180°, that is, to rotate clockwise for half a turn first, and then counterclockwise for half a turn, and so on. And each time after the rotation and during the intermittent period, the two carrier plates 501 are both flush with the upper surface of the welding table 300.

[0047] In some embodiments of the present application, the carrier plate 501 has a U-shaped structure. A turnover plate 503 is rotatably provided inside the carrier plate 501. The second fixture 502 is movably arranged on the turnover plate 503. One end of the turnover plate 503 is rotatably connected to the carrier plate 501 through a rotating shaft; the rotating shaft is rotatably matched with the carrier plate 501 through a damping bearing, and the rotating shaft extends outside the carrier plate 501 and is sleeved with a driven gear 504; the turnover plate 503 is rotatably arranged inside the carrier plate 501, and when the carrier plate 501 remains flush with the welding table 300, the turnover plate 503 also remains flush with the carrier plate 501.

[0048] In addition, an arc-shaped rack 505 is provided on the inner side of the installation notch 301 near the front end. When the upper surface of the carrier plate 501 remains flush with the upper surface of the welding table 300, the arc-shaped rack 505 meshes with one of the driven gears 504, and the upper surfaces of the two turnover plates 503 both remain parallel to the carrier plate 501. When the servo motor 609 drives the rotating column 604 to rotate half a turn, one of the driven gears 504 leaving the arc-shaped rack 505 first turns half a turn, and the other driven gear 504 also turns half a turn when entering the area of the arc-shaped rack 505. That is, the setting of the arc-shaped rack 505 enables the two turnover plates 503 to always keep their fronts facing up during the rotation interval of the carrier plate 501.

[0049] It should be noted that the turnover plate 503 is rotatably matched with the carrier plate 501 through a damping bearing. The function of the damping bearing is to prevent the turnover plate 503 from rotating randomly, ensuring that the turnover plate 503 can only rotate when its driven gear 504 meshes with the arc-shaped rack 505. A chute 506 is opened on the upper surface of the turnover plate 503. The length direction of the chute 506 is perpendicular to the length direction of the first linear slide 401. A displacement part 507 is slidably arranged in the chute 506. The second fixture 502 is arranged inside the displacement part 507. Both clamping jaws of the second fixture 502 extend out of the displacement part 507 and are provided with second clamping pieces 508. The displacement part 507 has a hollow internal structure, and the second fixture 502 is arranged inside the displacement part 507; and an opening for the clamping jaws of the second fixture 502 to pass through is opened on one side of the displacement part 507. Both second clamping pieces 508 are located outside the displacement part 507, and the two second clamping pieces 508 are symmetrically distributed up and down.

[0050] Further, a docking block 509 is provided on one side of the displacement part 507. The docking block 509 has a hollow structure, and a protruding block 510 is movably inserted into the interior of the docking block 509. A second linear slide 602 is provided on the upper surface of the seat plate 601. The second linear slide 602 is perpendicular to the first linear slide 401, and a docking sleeve 610 adapted to the protruding block 510 is provided at the movable end of the second linear slide 602. An electromagnet 511 is provided at the inner end of the docking block 509, and a permanent magnet block 514 is fixedly embedded at the inner end of the protruding block 510. When the electromagnet 511 is energized, the electromagnet 511 and the permanent magnet block 514 repel each other. That is, when the electromagnet 511 is energized, the electromagnet 511 can push the protruding block 510 to protrude outward; when the electromagnet 511 is de-energized, since the permanent magnet block 514 can attract the electromagnet 511, the protruding block 510 can retract into the docking block 509 inward.

[0051] Meanwhile, a strip-shaped notch 512 is formed on the side surface of the displacement part 507, and the docking block 509 is slidably arranged in the strip-shaped notch 512. A shock-absorbing spring 513 is connected between the end of the docking block 509 facing the second linear slide 602 and the inner end of the strip-shaped notch 512; in the natural state, the shock-absorbing spring 513 is in a compressed state. That is, the shock-absorbing spring 513 always applies a thrust to the docking block 509 toward the side away from the first linear slide 401. During the process of the second linear slide 602 pushing one displacement part 507 close to the first linear slide 401, when the crossbeam angle steel and the vertical beam angle steel are in contact, the shock-absorbing spring 513 can play a buffering role to avoid strong rigid collision between the two and damage to the equipment.

[0052] In the specific implementation process of this embodiment, first, the vertical beam angle steel is fixed by the first fixture 402, so that the vertical beam angle steel is parallel to the length direction of the welding table 300; then, the two crossbeam angle steels are respectively fixed by the two second fixtures 502, and the crossbeam angle steel is parallel to the width direction of the welding table 300; then, the first linear slide 401 is used to control the vertical beam angle steel to advance a certain distance, and then the second linear slide 602 is used to control a crossbeam angle steel on the front side to approach the vertical beam angle steel so that the two are in contact; after that, the welding robot arm 200 is used to weld the contact part. After the welding is completed, the second fixture 502 releases the welded crossbeam angle steel, and then the first linear slide 401 continues to advance a certain distance. At the same time, the servo motor 609 controls the rotary column 604 to rotate half a turn to swap the positions of the two carrier plates 501. At this time, the second linear slide 602 controls the displacement part 507 on the front side to approach the vertical beam angle steel. During the welding interval, the staff installs the next crossbeam angle steel on the second fixture 502 on the rear side, and so on.

[0053] It should be noted that each time the second linear slide 602 controls the movement of the displacement part 507 located on the front side, the electromagnet 511 on the back of the displacement part 507 needs to remain energized, so that the protruding block 510 is embedded in the docking sleeve 610. When the two carrier plates 501 need to exchange positions, the electromagnet 511 is de-energized to separate the protruding block 510 from the docking sleeve 610.

[0054] In addition, this embodiment further includes a PLC controller (not shown in the figure). The first linear slide 401, the second linear slide 502, the servo motor 609, the electromagnet 511, the first fixture 402, and the second fixture 502 are all communicatively connected to the PLC controller. The staff can control the above electrical components to execute in a specific order through the controller, so that no manual intervention is required during the entire welding process.

[0055] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.

[0056] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
