Description

Technical Field

[0001] The present invention relates to the technical field of welding, and specifically to an intelligent welding production line for galvanized sheets. Background Art

[0002] A galvanized sheet refers to a steel sheet with a layer of zinc plated on its surface; galvanization is an economical and effective anti-rust method that is often adopted, and about half of the world's zinc production is used for this process.

[0003] Generally, welding is one of the processes in the processing of the sheet production line, and its main function is to weld and fix between sheets; Regarding the welding direction, after retrieval, a welding device with a workpiece surface grinding function is disclosed, with the publication number: CN221640144U; Existing welding equipment usually has a significant improvement in solving problems such as welding slag and weld seams, but no targeted improvement has been made in the butt joint between sheets during welding. Among them, the problems existing in the butt joint of sheets are that some sheets will be bent to a certain extent due to reasons such as transportation, and most of them are located at the center of the sheet, while the edge hardly has this problem; The docking scheme usually adopted by existing docking equipment is to place the sheets on a plane and push the two sheets to move relative to each other for docking. If the sheets are slightly bent, this docking method cannot keep the docking surfaces of the two sheets parallel during docking. Please refer to the Figure 18 ; Another solution is to grab and dock through a robotic arm, but the cost of this method is very high. Summary of the Invention

[0020] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0022] Next, according to Figures 1 - 19 Describe the galvanized sheet intelligent welding production line provided by the embodiments of the present invention.

[0023] Please refer to Figures 1 - 19, an embodiment of the present invention provides a technical solution: a galvanized sheet intelligent welding production line, including a welding table 1 and a support frame 101 fixed on the welding table 1, and further including two first support plates fixed on both sides of the welding table 1. Two ends of each of the two first support plates are rotatably installed with second conveying rollers 203. A first conveyor belt 2 is connected between the two second conveying rollers 203. A second support plate perpendicular to the two first support plates is fixed between the two first support plates. Two ends of the second support plate are rotatably installed with first conveying rollers 202. A second conveyor belt 201 is connected between the two first conveying rollers 202; first drive motors are installed on the first support plates respectively. Output shafts of the two first drive motors are coaxially fixed to the second conveying rollers 203. When the first drive motors work, they drive the two second conveying rollers 203 to rotate relatively, and then drive the two first conveyor belts 2 to convey relatively; A second drive motor is installed on the second support plate. The output shaft of the second drive motor is coaxially fixed to the first conveying roller 202 to drive the rotation of the first conveying roller 202 through the second drive motor, and then drive the second conveyor belt 201 to convey; A welding mechanism installed between the second conveyor belt 201 and the first conveyor belt 2 welds the plate bodies 4 conveyed by the first conveyor belt 2 and the second conveyor belt 201; A docking mechanism installed on the welding table 1 and on both sides of the second conveyor belt 201 and the first conveyor belt 2 docks the opposite ends of the plate bodies 4 conveyed by the first conveyor belt 2 and the second conveyor belt 201, and welds between the two first conveyor belts 2 through cooperation with the welding structure; A blanking component installed on the welding table 1 conveys the welded plate bodies 4 to the second conveyor belt 201.

[0024] In the embodiment of the present invention, the two plate bodies 4 to be welded are conveyed relatively by the relatively conveying first conveyor belt 2. When the plate bodies 4 are conveyed to the designated position, the two plate bodies 4 are docked through the docking mechanism, so that the end faces of the two plate bodies 4 are in contact and parallel at the same time. Finally, the two plate bodies 4 are welded through the welding structure. Finally, the blanking component drives the two welded plate bodies 4 to lift and convey them to the second conveyor belt 201, and the two welded plate bodies 4 are conveyed to the next process through the second conveyor belt 201; Among them, the above-mentioned designated position means that one-third of the plate body 4 is located outside the first conveyor belt 2. Please refer to Figure 17 ; The present invention includes a blanking device - a welding device - a grinding device - a punching device - a palletizing device. The blanking device intermittently feeds materials synchronously onto two first conveyor belts 2. And the present invention is the welding device of this production line. After the welding work is completed by the present invention, the two welded plates 4 are conveyed to the grinding device through the second conveyor belt 201, then to the punching device after grinding, and finally to the palletizing device to complete the processes of the entire production line.

[0025] The welding mechanism includes two mounting plates 6 fixed to the welding table 1 and the support frame 101. On the opposite sides of the two mounting plates 6, a first axial slide rod 609 and a second axial slide rod 6010 are respectively fixed. The two mounting plates 6 are fixed by the first axial slide rod 609. The second axial slide rod 6010 is separately arranged and is located on the side of the welding table 1 facing the second conveyor belt 201. A first guide rod 601 and a second guide rod 602 are slidably mounted on the first axial slide rod 609 and the second axial slide rod 6010 respectively. Sliding members 605 are slidably mounted on both the first guide rod 601 and the second guide rod 602. A welding torch 603 for welding is fixed on the sliding member 605. A lead screw 604 is rotatably mounted on one side of both the first guide rod 601 and the second guide rod 602. The two sliding members 605 are respectively in threaded cooperation with the two lead screws 604. The two lead screws 604 are connected by a driving member.

[0026] In the embodiment of the present invention, both the first guide rod 601 and the second guide rod 602 are fixed to the conveying rods of the electric push rods mounted on the welding table 1 and the support frame 101. By the operation of the electric push rods, the first guide rod 601 and the second guide rod 602 move relatively or in opposite directions. The first axial slide rod 609 and the second axial slide rod 6010 provide guiding and limiting for the first guide rod 601 and the second guide rod 602. When the first guide rod 601 and the second guide rod 602 move relatively or in opposite directions, they drive the lead screws 604, the sliding members 605, and the welding torch 603 to move synchronously. When the driving member operates, the two lead screws 604 are synchronously driven to rotate, so as to drive the sliding member 605 and the welding torch 603 to move axially along the first guide rod 601 through the threaded cooperation between the lead screw 604 and the sliding member 605. Through the description of the conveying motion state, the two welding torches 603 can move relatively or in opposite directions, and the synchronous horizontal movement of the two welding torches 603 is realized. The effects of the relative movement of the two welding torches 603 are as follows: One, it can be applicable to plates 4 with different thicknesses. Two, when the docking mechanism completes the docking work of the two plates 4, when moving the plates 4, it can avoid damaging the welding torch 603 caused by the dynamic plates 4. Among them, the effect of the separately arranged second axial slide bar 6010 is that when the welding work is completed and the blanking component is used for blanking, if the second axial slide bar 6010 is arranged in the same way as the first axial slide bar 609, it will block the movement of the welded plate body 4 onto the second conveyor belt 201; It should also be noted that the electric push rod in this embodiment is not shown.

[0027] The driving member includes a limiting rod 608 rotatably installed between two mounting plates 6 and located at the end. Two limiting sleeves 6012 are slidably installed on the limiting rod 608. A follower frame 6013 is rotatably installed on the two limiting sleeves 6012. The two follower frames 6013 are respectively fixed to the first guide rod 601 and the second guide rod 602. And the two limiting sleeves 6012 are also connected to two first threaded sleeves 504 through a bevel gear set 6011; the bevel gear set 6011 includes two meshing bevel gears, and the two bevel gears are coaxially fixed to the first threaded sleeve 504 and the limiting sleeve 6012 respectively; Among them, a plurality of transmission strips are circumferentially and equidistantly fixed on the limiting rod 608, and the transmission strips are slidably matched with the transmission grooves formed on the inner wall of the limiting sleeve 6012; A second motor 606 is fixed on the support frame 101, and the output shaft of the second motor 606 is connected to the limiting rod 608 through a second transmission chain 607.

[0028] In the embodiment of the present invention, when the second motor 606 works, its output shaft drives the limiting rod 608 to rotate through the second transmission chain 607, so as to drive the two limiting sleeves 6012 to rotate synchronously through the cooperation of the transmission strips and the transmission grooves. When the limiting sleeve 6012 rotates, it drives the first threaded sleeve 504 to rotate through the bevel gear set 6011; Among them, when the first guide rod 601 and the second guide rod 602 move relatively or oppositely, the limiting sleeve 6012 is driven to axially slide on the limiting rod 608 through the follower frame 6013, so that the first guide rod 601 and the second guide rod 602 can be adjusted relatively and oppositely arbitrarily without losing drive; It should be noted that the second motor 606 in this embodiment uses a servo motor. Of course, a stepping motor, a DC motor, etc. can also be selected according to actual production requirements as long as the driving requirements are met. The present invention does not make specific limitations; It should also be noted that a notch 102 is also opened on the welding table 1 to give a movement space to one of the welding torches 603 located below when the two welding torches 603 move in opposite directions.

[0029] The blanking component includes a lifting frame 3 slidably installed on the welding table 1. The lifting frame 3 is arranged in a U shape, and two groups of conveying wheel sets are installed on the top of the lifting frame 3; The single set of conveying wheel sets includes a plurality of conveying wheels 301 arranged at equal intervals.

[0030] In the embodiment of the present invention, the first conveying wheel 301 and the last conveying wheel 301 are connected by a synchronous belt. A high-torque motor is installed in the lifting frame 3. The output shaft of the high-torque motor is connected to the first conveying wheel 301 or the last conveying wheel 301 through a gear set. When the high-torque motor works, its output shaft drives the first or the last conveying wheel 301 to rotate through the gear set, so that when one of the conveying wheels 301 rotates, it drives the other conveying wheel 301 to rotate through the synchronous belt, enabling the two conveying wheels 301 to rotate synchronously. An electric push rod (not shown in the figure) is also installed at the bottom of the lifting frame 3. The movable rod of the electric push rod is fixed to the lifting frame 3. When the electric push rod works, it drives the lifting frame 3 to rise or fall. When the lifting frame 3 rises, it first abuts against the plate body 4 through the conveying wheel 301. Then, as the lifting frame 3 continues to rise, it jacks up the plate body 4, and then conveys the plate body 4 through the rotation of the conveying wheel 301 to convey the plate body 4 onto the second conveyor belt 201.

[0031] The docking mechanism includes two clamping members arranged symmetrically, and the two clamping members are located between the two first conveyor belts 2. Among them, the clamping member includes a second docking plate 5010 and a first docking plate 509, and the centers of gravity of the second docking plate 5010 and the first docking plate 509 are both below. Moving components are installed on both sides of the first docking plate 509 and the second docking plate 5010, and the moving components are connected to the two clamping members; the shapes of the first docking plate 509 and the second docking plate 5010 include but are not limited to triangles or cones. Anti-slip layers are provided on the opposite sides of the second docking plate 5010 and the first docking plate 509.

[0032] In the embodiment of the present invention, when the moving component works, it first drives the second docking plate 5010 and the first docking plate 509 to move horizontally, and they move relatively during the horizontal movement. This relative movement clamps the plate body 4, so as to drive the two plate bodies 4 to move relatively after clamping the plate body 4 until the ends of the two plate bodies 4 abut. Among them, in this embodiment, the centers of gravity of the second docking plate 5010 and the first docking plate 509 are both downward, which means that the second docking plate 5010 and the first docking plate 509 are rotatably connected to the moving component, and this rotational connection is in a free rotation state, so that the second docking plate 5010 and the first docking plate 509 with anti-slip layers are always arranged relatively. Although the second docking plate 5010 and the first docking plate 509 will shake during the movement, their orientations will not have too large deviations, and their specific functions will be specifically described in the moving component.

[0033] The moving component includes four limiting plates 5, which are respectively located on both sides of the feeding member; A first constraint groove 501 and a second constraint groove 502 are formed in each of the four limiting plates 5; Bushings 5011 are movably installed in both the first constraint groove 501 and the second constraint groove 502. The bushing 5011 in the first constraint groove 501 is rotatably sleeved on the rotating shaft of the first docking plate 509, and the bushing 5011 in the second constraint groove 502 is rotatably sleeved on the rotating shaft of the first docking plate 509; wherein, the movable installation of the bushing 5011 means that the bushing 5011 can slide, roll, rotate along the path of the first constraint groove 501, and any combination of three or more; the function of the bushing 5011 is to reduce the friction during sliding and the smoothness of sliding.

[0034] The rotational movement of the second docking plate 5010 and the first docking plate 509 is connected to the relative moving member installed on the limiting plate 5.

[0035] In the embodiment of the present invention, the relative moving member is used to drive the second docking plates 5010 and the first docking plates 509 on both sides to move relatively; Wherein, since bushings 5011 are movably installed in both the first constraint groove 501 and the second constraint groove 502, and the second docking plate 5010 and the first docking plate 509 are rotatably installed in the bushing 5011. When the second docking plate 5010 and the first docking plate 509 move towards another second docking plate 5010 and the first docking plate 509, in fact, the distance between the second docking plate 5010 and the first docking plate 509 is restricted by the first constraint groove 501 and the second constraint groove 502, so that the distance between the second docking plates 5010 and the first docking plates 509 on both sides gradually decreases during the relative movement, so as to clamp the plate body 4 after the distance between the two decreases to a certain distance, and then clamp the plate body 4 and perform a horizontal movement; Wherein, the function of the center of gravity of the second docking plate 5010 and the first docking plate 509 being downward is that when the second docking plate 5010 and the first docking plate 509 move along the paths of the first constraint groove 501 and the second constraint groove 502, the side of the second docking plate 5010 provided with the anti-slip layer is always downward, and the side of the first docking plate 509 installed with the anti-slip layer is always upward, and the shaking during the process does not affect the clamping of the plate body 4.

[0036] The first constraint groove 501 and the second constraint groove 502 include an inclined front part, a connecting part, and a horizontal part; The distance between the front parts is greater than the distance between the horizontal parts, and the connecting part is located between the front part and the horizontal part.

[0037] In the embodiment of the present invention, the second constraint groove 502 and the first constraint groove 501 are mirror - set with respect to the center point of their distance. When the second docking plate 5010 slides in the first constraint groove 501, it is located at the front in the initial position. As it moves, the distance between it and the first docking plate 509 gradually decreases. When the second docking plate 5010 moves to the connection part, it clamps the plate body 4 through cooperation with the first docking plate 509. Then, during subsequent movement, the distance between the first docking plate 509 and the second docking plate 5010 will not decrease or increase, but only perform horizontal movement. Thus, through the cooperation of the first docking plate 509 and the second docking plate 5010, the plate body 4 is clamped to determine the horizontal positions of the two plate bodies 4 and then perform relative movement docking; Among them, the actual function of the connection part is the part that smoothly connects the front part and the horizontal part. When the second docking plate 5010 and the first docking plate 509 move to this position, the distance between them will decrease slightly. For example, the thickness of the plate body 4 is 2 cm of the first conveyor belt, and the distance between the second docking plate 5010 and the first docking plate 509 is 2 cm when they move to the connection part. When moving from the connection part to the horizontal part, the distance between the second docking plate 5010 and the first docking plate 509 will decrease to 1.9 cm. Since the clamping force of the plate body 4 as a workpiece is insufficient to cause deformation of the plate body 4, at this time, the anti - slip layer on the second docking plate 5010 or and the first docking plate 509 deforms, and this process will clamp the plate body 4; The technical effect achieved through the description of the above - mentioned motion state is that by driving the relative movement of the two second docking plates 5010 and the first docking plate 509, the clamping of the plate body 4, the clamping and carrying of the plate body 4 during movement, and the docking of the two plate bodies 4 can be realized. Its structure is simple, the efficiency is high, and there will be no deviation in docking.

[0038] On the limiting plate 5, the first pressing plate 7 and the second pressing plate 701 are fixedly arranged oppositely, and the first pressing plate 7 and the second pressing plate 701 cooperate with the first docking plate 509 and the second docking plate 5010 respectively; Among them, both the first pressing plate 7 and the second pressing plate 701 are inclined.

[0039] In an embodiment of the present invention, after the first docking plate 509 and the second docking plate 5010 clamp the plate body 4, they move to the horizontal portions of the first constraint groove 501 and the second constraint groove 502. The horizontal portions are for horizontal movement, so that the first docking plate 509 and the second docking plate 5010 gradually cooperate with the first pressing plate 7 and the second pressing plate 701. The first pressing plate 7 and the second pressing plate 701 apply a pressing force to the first docking plate 509 and the second docking plate 5010, so as to avoid small deformations after the first docking plate 509 and the second docking plate 5010 clamp the plate body 4, resulting in incomplete clamping and squeezing of the plate body 4. That is, the deformations of the first docking plate 509 and the second docking plate 5010 cause the correction work of the plate body 4 not to be completed well; In this embodiment, after the first docking plate 509 and the second docking plate 5010 complete the clamping of the plate body 4, through the cooperation with the first pressing plate 7 and the second pressing plate 701, the first pressing plate 7 and the second pressing plate 701 apply a pressing force to the first docking plate 509 and the second docking plate 5010, so as to eliminate the deformations of the first docking plate 509 and the second docking plate 5010.

[0040] The relative moving member includes a bidirectional lead screw 503 rotatably installed on the limiting plate 5. Both ends of the bidirectional lead screw 503 are sleeved with first threaded sleeves 504 that are in threaded cooperation with it. The top and bottom of the first threaded sleeve 504 are both fixed with slide bars 506; Sliding sleeves 505 are coaxially and rotatably installed on the rotating shafts of the second docking plate 5010 and the first docking plate 509. The sliding sleeves 505 are sleeved on the slide bars 506 and are slidably connected to them; A first motor 507 is fixed on the limiting plate 5. The output shaft of the first motor 507 is connected to the bidirectional lead screw 503 through the first motor 507.

[0041] In an embodiment of the present invention, when the first motor 507 works, its output shaft drives the bidirectional lead screw 503 to rotate through a first transmission chain 508. When the bidirectional lead screw 503 rotates, it drives the two first threaded sleeves 504 to move relatively through the threaded cooperation with the two first threaded sleeves 504. When the first threaded sleeve 504 moves, it drives the slide bar 506 to move synchronously, so as to drive the second docking plate 5010 and the first docking plate 509 to move synchronously through the slide bar 506 and the sliding sleeve 505; Furthermore, the two second docking plates 5010 and the first docking plate 509 move relatively. And because the sliding sleeve 505 and the slide bar 506 are slidably connected, when the two second docking plates 5010 and the first docking plate 509 move relatively, the relative movement of the second docking plate 5010 and the first docking plate 509 is not affected.

[0042] During use (operation), the plate body 4 is conveyed relatively by two first conveyor belts 2. After the plate body 4 moves to the specified position, the two plate bodies 4 are aligned at their ends through the docking mechanism; Then, the two plate bodies 4 are welded and fixed through the welding mechanism; Finally, the plate body 4 that has completed welding is lifted and conveyed onto the second conveyor belt 201 through the blanking assembly.
