Description

Technical Field

[0001] The present invention relates to the technical field of welding, and in particular to a welding device and a welding method for steel plates. Background Art

[0002] With the continuous development of industrialization, early factories will undergo factory building renovations. During the construction process, steel plates are needed to cover the top of the expanded area to prevent rainwater and other falling objects from falling into the construction site, while also providing a foundation for subsequent construction work.

[0003] There are two main methods for welding two steel plates during construction. One is to lift the two steel plates with multiple cranes and then lift the construction workers to a high place to carry out construction work. This requires the qualifications of the operators. At the same time, high-altitude work requires a large ground area, which needs to accommodate the ground area of ​​multiple cranes. The other is to install the steel plates by crane after welding on the ground. During installation, the dimensions of the site need to be repeatedly measured. However, since welding will cause the dimensions to change, the welded steel plates may need to be cut off at the weld points, readjusted and welded again. Repeated welding has a great impact on the interfaces of the steel plates, which is not conducive to later use and will waste a lot of time and manpower. Summary of the Invention

[0045] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many other forms and is not limited to the embodiments described herein.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0048] It should be emphasized and explained here that the various connection methods involved in the present invention can be arbitrary unless specifically stated. For example, the fixed connection can be achieved by bolts and nuts, detachable fixation, welding or one-piece molding, the sliding connection can be achieved through grooves and guide rail structures of various shapes, and the rotating connection can be achieved through hinges, rotating shafts, etc., as long as the existing method can achieve the corresponding connection relationship.

[0049] The following combination Figure 1-6 The welding device and welding method involved in the present invention are further explained.

[0050] In one embodiment of a welding device 1, the device 1 includes a first drive mechanism 11, two suction mechanisms 12, and two welding mechanisms 13. The first drive mechanism 11 has two retractable connectors and a lifting lug 113 for a crane 300 to lift the connector. The two connectors extend and retract in parallel directions. Each suction mechanism 12 is connected to each connector in a one-to-one correspondence, allowing it to move under the influence of the connector's extension and retraction. Each suction mechanism 12 is used to suction two steel plates 100, positioning them in an L-shaped arrangement. Each welding mechanism 13 is mounted on each suction mechanism 12 in a one-to-one correspondence, and is used to weld the two steel plates 100 together.

[0051] In this embodiment, the two adsorption mechanisms 12 can make the two steel plates 100 into an L-shape, and the two welding mechanisms 13 can perform welding after the steel plates 100 are in an L-shape. Then, driven by the first driving mechanism 11, spot welding and full welding after spot welding can be performed along the weld between the two steel plates 100. This replaces manual labor in high-altitude operations and solves the technical problems of time-consuming and labor-intensive existing welding methods.

[0052] It should be emphasized that in this embodiment, the two steel plates 100 are welded after being hoisted, wherein the two adsorption mechanisms 12 can make the two steel plates 100 form an L shape. The welding mechanism 13 is preferably a small laser welding gun, which can be easily installed and fixed.

[0053] In an embodiment of a welding device 1, the adsorption mechanism 12 includes a connecting plate 121, a first adsorption module 122, a second adsorption module 123 and a driving module 124. One side of the connecting plate 121 is fixedly connected to the connecting piece. The first adsorption module 122 and the second adsorption module 123 are used to adsorb each steel plate 100. One end of the connecting plate 121 is fixedly connected to the first adsorption module 122, and the other end is rotatably connected to the second adsorption module 123. The driving module 124 is fixedly connected to the connecting plate 121, and its output end is connected to the second adsorption module 123. The driving module 124 is used to drive the second adsorption module 123 to rotate relative to the first adsorption module 122 so as to be able to adjust the angle between the two steel plates 100.

[0054] In this embodiment, two adsorption modules are provided, which can be used to respectively adsorb the corners of two different steel plates 100, and the setting of the driving module 124 can adjust the angle between the first adsorption module 122 and the second adsorption module 123, for example, from a range of 30 degrees to 120 degrees, so that it can better match the requirements of different sizes, and the two steel plates 100 form L-shaped or V-shaped shapes.

[0055] Specifically, to limit the angle, refer to Figure 6 As shown in FIG. 1 , a photoelectric switch 127 can be provided, and the photoelectric switch 127 is communicatively connected to the drive module 124. A protrusion is provided on the second adsorption module 123. When the rotation angle reaches the required value, the protrusion just extends into the photoelectric switch 127, so that the drive module 124 is stopped at this position by a signal generated. In addition, the photoelectric switch 127 can be easily disassembled or slidable, so that it can adapt to different angles. The photoelectric switch 127 can be specifically installed on the telescopic member 112 or the connecting plate 121, and can be supported by a bracket or a fixed block structure. Alternatively, the photoelectric switch 127 can be replaced with a fixed plate or block-shaped structure, and the position can be limited by direct physical contact.

[0056] To be more specific, the driving module 124 can be a driving part such as a cylinder or an oil cylinder, or the two driving modules 124 in the two adsorption mechanisms 12 can both be pneumatic rods under the same air source, so that they can be easily adjusted together. When the two driving modules 124 are separate, they can also be set to start at the same time, so that the two steel plates 100 can maintain large-surface flatness during movement. Of course, they can also be controlled separately, through the electric control limit of the photoelectric switch 127 or the physical limit of the block. After the limit is set, both sides reach the limit position, and the large-surface flatness can also be maintained.

[0057] In an embodiment of the welding device 1, the first adsorption module 122 includes a first mounting plate 1221, a plurality of first telescopic elements 1222, and a plurality of first adsorption members 1223. Each first telescopic element 1222 is fixedly mounted on one side of the first mounting plate 1221, and each first adsorption member 1223 is mounted one-to-one at the end of each first telescopic element 1222 facing away from the first mounting plate 1221. The second adsorption module 123 includes a second mounting plate 1231, a plurality of second telescopic elements 1232, and a plurality of second adsorption members 1233. Each second telescopic element 1232 is fixedly mounted on one side of the second mounting plate 1231, and each second adsorption member 1233 is mounted one-to-one at the end of each second telescopic element 1232 facing away from the second mounting plate 1231.

[0058] In this embodiment, specifically, the first telescopic element 1222 and the second telescopic element 1232 can be hydraulic rods or pneumatic rods, preferably arranged in a matrix. Both the hydraulic and pneumatic sources can be located externally, such as on the first drive mechanism 11. By providing the first telescopic element 1222 and the second telescopic element 1232, the positional relationship between the two steel plates 100 can be adjusted after adsorption, thereby enabling better welding. The first suction member 1223 and the second suction member 1233 can be formed in a variety of structures, with those that facilitate the generation and removal of adsorption force being preferred. For example, in one embodiment of the welding device 1, the first suction member 1223 is an electromagnet or a vacuum suction cup. And / or the second suction member 1233 is an electromagnet or a vacuum suction cup. Compared to conventional magnets, the use of electromagnets and vacuum suction cups facilitates the expansion and contraction of the connector of the first drive mechanism 11, driving the overall movement of the adsorption mechanism 12. Conventional magnets, however, are difficult to remove and hinder the expansion and contraction of the connector.

[0059] In an embodiment of a welding device 1, the adsorption mechanism 12 also includes a first positioning member 125 and a second positioning member 126. The first positioning member 125 is connected to the first adsorption module 122. A first notch 1251 is provided on the first positioning member 125. The inner wall of the first notch 1251 can abut against the adjacent surface of the steel plate 100 and make the steel plate 100 parallel to the first mounting plate 1221 to position the steel plate 100. The second positioning member 126 is connected to the second adsorption module 123. A second notch 1261 is provided on the second positioning member 126. The inner wall of the second notch 1261 can abut against the adjacent surface of the steel plate 100 and make the steel plate 100 parallel to the second mounting plate 1231 to position the steel plate 100.

[0060] In this embodiment, by providing the first positioning member 125 and the second positioning member 126, the steel plate 100 can be positioned more conveniently, so that the steel plate 100 maintains a certain flatness before being adsorbed, that is, it can be parallel to the two mounting plates. After the positioning is completed, it is adsorbed by the first adsorption module 122 and the second adsorption module 123 to fix the steel plate 100. The positioned steel plate 100 can maintain its position. For example, when the two adsorption mechanisms 12 are at 90 degrees, the two steel plates 100 are also vertical, which is convenient for subsequent welding.

[0061] Specifically, the first positioning member 125 and the second positioning member 126 can be the same structural member, and their structural shape can be an L-shaped block or plate-shaped structural member, which can be fixedly connected to the first mounting plate 1221 and the second mounting plate 1231 by welding, bolts, etc.

[0062] In an embodiment of a welding device 1 , the welding device 1 further includes two cameras 14 , each camera 14 being installed one-to-one on each connecting plate 121 , each camera 14 being located between a first positioning member 125 and a second positioning member 126 , and being used to observe the gap between the two steel plates 100 .

[0063] In this embodiment, by setting up a camera 14, the corresponding relationship between the two steel plates 100 can be better observed. Specifically, the camera 14 can be connected to a mobile phone or a computer, which can be convenient for staff to view. For example, after the staff observes through the camera 14 that the two steel plates 100 are in the appropriate position under the drive of the two telescopic elements, they stop the telescopic elements from extending and contracting, and then control the welding mechanism 13 to perform welding.

[0064] In an embodiment of a welding device 1, the welding device 1 also includes two second driving mechanisms 15 and two mounting seats 16, a second driving mechanism 15 and a mounting seat 16 form a group, a group of second driving mechanisms 15 and mounting seats 16 are fixedly connected to a connecting plate 121, and the driving ends of each second driving mechanism 15 are connected to each mounting seat 16 one by one, and are used to drive the mounting seat 16 to rotate, and each welding mechanism 13 and each camera 14 are installed on each mounting seat 16 one by one.

[0065] In this embodiment, by setting up a second driving mechanism 15, the camera 14 and the welding mechanism 13 can be better aligned between the two steel plates 100, which can reduce the accuracy requirements during the expansion and contraction of the two telescopic elements, reduce the complexity of the overall device, and also enable the welding mechanism 13 to be better welded to the opposite side walls of the two steel plates 100, thereby achieving a better welding effect.

[0066] In an embodiment of a welding device 1, the first driving mechanism 11 includes a box body 111, two driving units and two telescopic parts 112. A receiving space is provided in the box body 111, and the two driving units are both received in the receiving space. The driving end of each driving unit is connected to each telescopic part 112 one by one, and is used to drive the telescopic part 112 to extend and retract. The lifting ear 113 is fixedly connected to the outer wall of the box body 111.

[0067] In this embodiment, by providing a box 111, two drive units can be conveniently accommodated to form a whole, and the lifting lugs 113 can be conveniently provided to lift the whole, and it can also play a protective role. Specifically, the two drive units are fixedly connected to the inner wall of the box 111 by bolts or the like, and the drive unit can be a cylinder. By driving the two telescopic parts 112 to retract and retract, the adsorption mechanism 12 and the welding mechanism 13 can be driven to retract and retract as a whole, which can facilitate welding. In addition, it can be understood that by providing two drive units, the two telescopic parts 112 can be driven to retract and retract respectively, that is, the two adsorption mechanisms 12 and the welding mechanism 13 may not move at the same time during welding. In this way, one side can be welded first and then the other side, which has a fixing effect and a good welding effect.

[0068] The present invention also relates to a welding method for a steel plate 100, which is combined with the corresponding method of the above welding device. Figure 1-6 as well as Figure 7-8 , applied to the welding device 1 in the previous embodiment, the welding method includes the following steps:

[0069] S100 , placing a steel plate 100 against the first notch 1251 of the first positioning member 125 to position the steel plate 100 .

[0070] S200 , after the steel plate 100 abuts against the first notch 1251 , the first suction module 122 extends the first telescopic element 1222 and sucks the steel plate 100 through the first suction member 1223 .

[0071] S300 , placing a steel plate 100 against the second notch 1261 of the second positioning member 126 to position the steel plate 100 .

[0072] S400 , after the steel plate 100 abuts against the second notch 1261 , the second adsorption module 123 extends the second telescopic element 1232 and adsorbs the steel plate 100 through the second adsorption member 1233 .

[0073] S500 , after the two steel plates 100 are adsorbed, the welding device 1 and the two steel plates 100 are lifted by the crane 300 .

[0074] S600 , the crane 300 adjusts the positions of the two steel plates 100 so that one of the steel plates 100 rests on the welding point of the angle steel 200 .

[0075] S700 , the first telescopic element 1222 and the second telescopic element 1232 push the side walls of the two steel plates 100 closer together under the monitoring of the camera 14 until a weldable weld is formed.

[0076] S800 , adjusting the angle between the two adsorption mechanisms 12 so that the two steel plates 100 are placed on the two corresponding welding points of the angle steel 200 .

[0077] S900 , the welding mechanism 13 extends to weld the two steel plates 100 , and under the drive of the first driving mechanism 11 , spot welding is performed along the extending direction of the weld and full welding is performed after spot welding.

[0078] S1000 , welding the contact positions of the two steel plates 100 and the angle steel 200 .

[0079] S1100 , after welding is completed, the welding device 1 removes the adsorption force, and the crane 300 removes the welding device 1 .

[0080] In this embodiment, the welding method of this embodiment is applied to the welding device 1, which can facilitate welding. Before welding, the adsorption is mainly performed by the adsorption mechanism 12, and the distance between the two steel plates 100 is adjusted to meet the welding requirements. Then, the steel plates 100 are lifted by the crane 300 and docked with the angle steel 200. During the docking process, the angle between the two adsorption mechanisms 12 is adjusted to facilitate the two steel plates 100 to be placed on the angle steel 200. Finally, the welding is performed by the welding mechanism 13. During the welding process, one side is completed first, and then the other side is completed. The two sides can be spot welded in sequence, and then the two sides can be fully welded in sequence. Alternatively, one side can be spot welded and fully welded first, and then the other side can be spot welded and fully welded. The welding method of this embodiment can replace manual high-altitude welding, solving the technical problem of time-consuming and labor-intensive existing welding methods.

[0081] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
