[0001] This application relates to the field of welding technology, and in particular to welding equipment. Background Technology

[0002] The production of steel structural components requires welding technology. Currently, the main methods for welding steel structures in confined spaces and with high welding difficulty include manual welding and traditional industrial robot welding.

[0003] However, manual welding requires human intervention during the welding process, resulting in a large workload, inconsistent processing quality, and susceptibility to welding defects due to subjective judgment. This also leads to high personnel and equipment costs and low production efficiency. Using traditional industrial robots for welding requires specialized technicians for programming, thus demanding high skill levels from operators. The initial programming preparation time is lengthy, resulting in low production efficiency. Furthermore, the large space requirements of traditional industrial robots limit their applicability. Utility Model Content

[0004] Therefore, it is necessary to provide a welding equipment that addresses the aforementioned issues of low production efficiency and the inability to simultaneously guarantee production costs and applicability.

[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0029] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0032] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0033] The production of steel structural components requires welding technology. Currently, for steel structures with confined spaces and high welding difficulty, the main welding methods include manual welding and traditional industrial robot welding. However, manual welding requires human intervention during the welding process, resulting in a large workload, inconsistent processing quality, and susceptibility to welding defects due to subjective judgment. This also leads to high personnel and equipment costs and low production efficiency. Traditional industrial robot welding requires specialized technicians to program the robots, thus demanding a high level of skill from operators. The initial programming preparation time is long, resulting in low production efficiency. Furthermore, traditional industrial robots occupy a large space, limiting their applicability.

[0034] Therefore, there is an urgent need for welding equipment that can reduce the skill requirements of operators, shorten preparation time, improve production efficiency, and expand the scope of application.

[0035] See Figure 1 and Figure 2 One embodiment of this application provides a welding device, including a transport mechanism 1, a welding mechanism 2, and a control mechanism 3. The transport mechanism 1 transports the welding mechanism 2, enabling it to be quickly moved to the vicinity of the structure to be welded. The control mechanism 3 controls the welding mechanism 2, allowing workers to perform welding operations on the structure.

[0036] In a specific configuration, the carrier mechanism 1 is equipped with a wire feeding assembly 11, and the welding mechanism 2 is connected to the wire feeding assembly 11 to feed the welding wire to the welding mechanism 2 for use. The welding mechanism 2 is detachably mounted on the carrier mechanism 1, allowing it to be removed from the carrier mechanism 1. This enables the welding mechanism 2 to be installed independently around the structure to be welded, effectively saving space around the welded structure and thus expanding its applicability.

[0037] The welding mechanism 2 is equipped with a vision sensor 24 for identifying weld seams. The vision sensor 24 can automatically identify the start and end points of the weld seams, eliminating the need for manual alignment of the welding head 23 of the welding mechanism 2. This effectively simplifies the operation process, shortens the pre-weld preparation time, and improves production efficiency.

[0038] The control mechanism 3 includes a main controller 31 and a control key assembly 32. The main controller 31 is mounted on the transport mechanism 1 and connected to the welding mechanism 2 and the vision sensor 24. The vision sensor 24 transmits the start and end point information of the weld seam it captures to the main controller 31, so that the main controller 31 can control the welding mechanism 2 to move and weld the seam after confirming the information. The control key assembly 32 is mounted on the welding mechanism 2 or the transport mechanism 1 and connected to the main controller 31. The control key assembly 32 allows for rapid control of the welding mechanism 2 to perform welding operations, effectively simplifying the operation process, shortening pre-welding preparation time, and improving production efficiency.

[0039] When using the welding equipment of this application, the transport mechanism 1 can be moved to the vicinity of the welding site first, and then the welding mechanism 2 can be removed from the transport mechanism 1 and fixed around the predetermined welding structure, so that the welding head 23 of the welding mechanism 2 is aligned with the weld seam, and the starting and ending points of the weld seam are automatically identified by the vision sensor 24 with the assistance of the control key assembly 32, so that the welding head 23 of the welding mechanism 2 can move along the predetermined welding path to perform welding. While the vision sensor 24 transmits visual information to the main controller 31, the operator can transmit the selected process information to the main controller 31 through the control key assembly 32, so that the main controller 31 can quickly control the welding mechanism 2 to perform welding operations.

[0040] In summary, the welding equipment of this application can automatically identify the start and end points of the weld seam through the vision sensor 24, eliminating the need for manual alignment of the welding head 23 of the welding mechanism 2. At the same time, the welding mechanism 2 can be quickly controlled to perform welding operations through the control key assembly 32, effectively simplifying the operation process, shortening the pre-weld preparation time, and improving production efficiency. In addition, by setting the wire feeding assembly 11 on the carrier mechanism 1 and making the welding mechanism 2 removable from the carrier mechanism 1, the welding mechanism 2 can be installed independently around the structure to be welded, effectively saving the space occupied around the welding structure and thus improving the applicability.

[0041] See Figure 1 and Figure 2 In one embodiment, the welding mechanism 2 includes a robotic arm 21 and a welding assembly 22. The robotic arm 21 is detachably mounted on the transport mechanism 1, and the welding assembly 22 is mounted on the robotic arm 21 and connected to the wire feeding assembly 11. The robotic arm 21 can drive the welding assembly 22 to perform welding at more angles. Specifically, the welding assembly 22 of the welding mechanism 2 has a welding head 23, and a vision sensor 24 is mounted on the welding head 23 so that the vision sensor 24 can better identify the start and end points of the weld.

[0042] In addition, the robotic arm 21 is equipped with several sensors. When the operator moves the welding head 23 to allow the vision sensor 24 to automatically identify the start and end points of the weld, the sensors on the robotic arm 21 can capture and record the movement of the robotic arm 21 in real time. This allows the operator to program software based on the movement data, automatically generating program code that describes the movement trajectory and action instructions of the robotic arm 21, including parameters such as arc initiation, swing amplitude, frequency, speed, and arc termination. The operator can further optimize and adjust the program parameters later, and then upload the generated program to the main controller 31 for verification and testing. The simulation environment is used to ensure the correctness and safety of the program. After the test is completed, the operator can start the welding mechanism 2 to perform the welding task. The robotic arm 21 can move the welding head 23 along the welding path and perform the welding operation according to the predetermined path and action instructions.

[0043] See Figure 1-Figure 3 In one embodiment, the welding equipment further includes a ground rail mechanism 4, and the welding mechanism 2 is equipped with an adsorption component 25. The welding mechanism 2 is detachably connected to the ground rail mechanism 4 or the transport mechanism 1 via the adsorption component 25. The ground rail mechanism 4 can assist the welding mechanism 2 in performing welding operations more effectively.

[0044] Specifically, the ground rail mechanism 4 includes an adsorption base 41 and a mounting base 42. The mounting base 42 is slidably disposed on the adsorption base 41, and the welding mechanism 2 is detachably connected to the mounting base 42 via the adsorption assembly 25. When the welding mechanism 2 needs to perform welding operations on a large area, the adsorption base 41 of the ground rail mechanism 4 can be fixed around the structure to be welded, so that the welding mechanism 2 can move through the mounting base 42, which can slide relative to the adsorption base 41, during welding, thereby increasing the area that the welding mechanism 2 can weld.

[0045] More specifically, the ground track mechanism 4 also includes a driver 43 connected to the main controller 31. The driver 43 is mounted on the adsorption base 41 and connected to the mounting base 42. The driver 43 can drive the mounting base 42 to slide on the adsorption base 41, thereby moving the welding mechanism 2 and increasing the welding area that the welding mechanism 2 can weld. That is, when the welding mechanism 2 needs to perform a large-area welding operation, the main controller 31 can give the driver 43 a corresponding signal, so that the driver 43 can drive the mounting base 42 to slide on the adsorption base 41, thereby moving the welding mechanism 2 and assisting the welding mechanism 2 in performing the welding operation.

[0046] See Figure 1 and Figure 2 In one embodiment, the adsorption assembly 25 includes a chassis and multiple adsorption elements. The chassis has a first side and a second side facing away from each other. The welding mechanism 2 is disposed on the first side, and the multiple adsorption elements are disposed on the second side. The adsorption assembly 25 can ensure the stability of the welding mechanism 2 adsorbed onto the ground rail mechanism 4 or the transport mechanism 1 through the multiple adsorption elements.

[0047] Specifically, in one embodiment, the adsorption element includes a permanent magnet, and both the ground rail mechanism 4 and the transport mechanism 1 are provided with magnetic components so that the permanent magnet can form an adsorption force when it comes into contact with the ground rail mechanism 4 or the transport mechanism 1. The magnetic components may include magnetic plates or iron plates. According to the principle of magnetism, magnets of the same polarity repel each other, while magnets of different polarities attract each other. The permanent magnet, through its own magnetic field, can continuously generate magnetic force to adsorb onto the magnetic components on the ground rail mechanism 4 and the transport mechanism 1. By including a permanent magnet in the adsorption element, the above structure allows the adsorption assembly 25 to have advantages such as simple structure, no need for external power supply, and high stability, and generally will not damage or deform the adsorbed object.

[0048] In another embodiment, the adsorption element includes an electromagnet, a power supply and a metal plate are provided on the chassis, the electromagnet is disposed on the metal plate and electrically connected to the power supply. The power supply can supply power to the electromagnet to generate a magnetic field, thereby enabling the metal plate to form an adsorption force when it comes into contact with the ground track mechanism 4 or the carrying mechanism 1.

[0049] In another embodiment, the adsorption element includes a vacuum adsorption disk, and a vacuum pump is provided on the chassis, with the vacuum adsorption disk connected to the vacuum pump. The vacuum pump can extract the gas in the vacuum adsorption disk, so that the vacuum adsorption disk can form a negative pressure environment with the ground rail mechanism 4 or the carrier mechanism 1, thereby adsorbing and connecting with the ground rail mechanism 4 or the carrier mechanism 1.

[0050] See Figure 1 and Figure 2 In one embodiment, the control key assembly 32 is disposed on the welding head 23 to facilitate operation during the experiment. Specifically, the control key assembly 32 includes start / end point control keys and process information control keys, both of which are disposed on the welding head 23 of the welding mechanism 2. More specifically, multiple process information control keys are provided, and each process information control key corresponds to a different welding process. When the user moves the welding head 23 to the start / end point of the weld, they can directly determine the start / end point by pressing the start / end point control key, and simultaneously select the corresponding process information control key to directly determine the corresponding process (flat welding, far welding, overhead welding, circular arc welding, etc.), improving ease of use.

[0051] In one embodiment, the transport mechanism 1 has a first support platform 12 and a second support platform 13. A wire feeding assembly 11 is disposed on the top surface of the first support platform 12, and a welding mechanism 2 is disposed on the top surface of the second support platform 13. The distance between the first support platform 12 and the bottom surface of the transport mechanism 1 is greater than the distance between the second support platform 13 and the bottom surface of the transport mechanism 1. By making the height of the wire feeding assembly 11 on the transport mechanism 1 higher than the height of the welding mechanism 2 on the transport mechanism 1, it is easier for the wire feeding assembly 11 to perform wire feeding operations on the transport mechanism 1.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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.

[0053] The embodiments described above are merely illustrative of several implementation methods of this application, 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 those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
