Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to an intelligent welding robot. Background Technology

[0002] Steel requires welding, and currently welding in my country is still mainly done manually. Driven by multiple factors, the trend of machines replacing humans is inevitable. The quality of manual welding is inconsistent and cannot meet the increasingly higher welding requirements. Therefore, using intelligent welding robots to replace manual welding work has the advantages of intelligence, efficiency, and wide applicability. Existing welding robots need to use visual positioning technology to determine the position of the workpiece and the weld seam through visual positioning devices, thereby planning the welding path to perform welding work on the workpiece.

The robot also includes a cleaning unit for cleaning the ends of the first electrode and the second electrode that are in contact with the surface of the weldment. The cleaning unit includes a moving component, the output end of which is connected to the cleaning component. The moving component drives the cleaning component to move in three-dimensional space, so that the cleaning component slides into contact with the ends of the first electrode and the second electrode that are in contact with the surface of the weldment.

Summary of the Invention

[0016] Furthermore, the adsorption unit includes a sliding block, an electric telescopic rod, and an adsorption element;

[0017] A slide rail is horizontally arranged on the inner wall of the receiving cavity. The two sides of the sliding block are embedded in the slide rail and slide within the receiving cavity. The driving unit is connected to the sliding block and controls the movement of the sliding block.

[0018] The sliding block has a storage groove on its side, and the suction element is installed in the storage groove. The electric telescopic rod is installed on the sliding block and connected to the suction element to control the suction element to move in and out of the storage groove.

[0019] Furthermore, the adsorption element includes an adsorption frame, an adsorption port, an adsorption channel, and an air jet head;

[0050] In existing technologies, the mobility of welding robots is often used to improve flexibility and portability. However, simply adding wheels to the bottom of the welding robot can easily affect welding accuracy during welding. In actual welding work, different production lines are usually set up according to different welding tasks. When switching production lines, current welding robots cannot be guaranteed to be suitable for different production lines. Problems such as height mismatch or misalignment between the welding table and the welding robot can easily occur, making welding robots highly limited when changing usage scenarios. In addition, welding robots generate welding slag and fumes during use, and current cleaning equipment is bulky and occupies a lot of space.

[0051] This invention provides an intelligent welding robot, such as Figure 1 As shown, in this embodiment, the intelligent welding robot includes a base, a robotic arm 1, and a welding unit 2; the base and... Figure 2The support platform 3 in the production line shown is connected. In other embodiments, the support platform 3 can be set in other structures such as gantry frames. The robotic arm 1 is mounted on the base. The welding unit 2 is set on the output end of the robotic arm 1. The welding unit 2 is a prior art used for welding and will not be described in detail in this embodiment.

[0052] The visual positioning device 10 is installed on one side of the welding torch in the welding unit, enabling it to move with the welding torch. It is detachable, making it easy to disassemble and maintain. With the setting of the visual positioning device 10, the welding path is autonomously extracted by intelligent matching and recognition from the model to the actual object. One worker can take care of 5-10 welding robots, reducing reliance on manual labor and realizing an unmanned welding production line.

[0053] Example 1

[0054] To ensure connection stability and enable the robotic arm 1 to be stably installed and used at different heights, making it suitable for various application scenarios, the base is configured as a mounting base 4 and a connecting base 5. The two ends of the mounting base 4 are detachably connected to the support platform 3 and the connecting base 5, respectively. The mounting base 4 is primarily designed for a stable connection with the support platform 3. Figure 3 As shown, the connecting seat 5 adopts a structure that is smaller at the top and larger at the bottom to ensure stable connection with the support platform 3; multiple connecting seats 5 are provided, and the number of connecting seats 5 used is selected according to different installation heights. In this embodiment, for example... Figure 4 As shown, there are two connecting seats 5, which are connected end to end in the height direction to define the installation position of the robotic arm 1. The connecting seats 5 are located on the upper end of the mounting seat 4 and are detachable from the mounting seat 4. The connecting seats 5 are connected by bolts to mount the robotic arm 1 on the connecting seats 5. In this embodiment, the detachable connection between the mounting seat 4, the support platform 3, and the connecting seats 5 is set as a bolt connection. Reinforcing sheets are provided on the side walls of the mounting seat 4 and the connecting seats 5 to improve the connection strength between the mounting seat 4 and the connecting seats 5 and improve the stability of the robotic arm 1 installation.

[0055] To improve the applicability of welding robots and enable their use in situations where a welding table is unavailable, thus meeting temporary and emergency needs; such as Figure 5 As shown, a receiving cavity 6 is provided on the mounting base 4 and the connecting base 5. Multiple foldable support plates 7 are arranged inside the receiving cavity 6. In this embodiment, three support plates 7 are provided. When unfolded, the support plates 7 extend out of the receiving cavity 6 and form a welding area on one side of the connecting base 5 for placing the workpiece. This welding area is located at the upper end of the support plate 7. During welding, the workpiece to be welded is placed on the upper end of the unfolded support plate 7, and the unfolded support plate 7 is used as a welding table for welding. Figure 6As shown, the support plates 7 are hinged together, and each support plate 7 is provided with a through-hole limiting groove 71. It also includes a limiting rod 72 that can pass through multiple limiting grooves 71 in sequence. After the support plate 7 is unfolded, the limiting rod 72 is inserted to limit the unfolding of the support plate 7 and fold it, thereby improving the stability of the support plate 7 after unfolding and improving the safety of welding work.

[0056] To further improve the stability of the support plate 7 as a welding station and prevent it from tipping over during welding, a closing plate 61 is provided on the receiving cavity 6. The closing plate 61 can close the opening of the receiving cavity 6. Specifically, the closing plate 61 and the opening of the receiving cavity 6 can be connected by a snap-fit, allowing the receiving cavity 6 to be closed when the support plate 7 is not in use to prevent external impurities from entering and maintain an overall aesthetic appearance. When the support plate 7 needs to be used, the closing plate 61 can be easily disassembled. Figure 7 As shown, the bottom of the support plate 7 is provided with a insertion groove 73. In this embodiment, the insertion groove 73 is set in a "V" shape. The insertion groove 73 is divided into two parts and is respectively set at the bottom of the two support plates 7. When the two support plates 7 are unfolded, the insertion groove 73 cooperates to form a "V" shape. The middle part of the opening and closing plate 61 can be folded. The opening and closing plate 61 can be folded into a "V" shape and its top is inserted into the insertion groove 73 to support the support plate 7. This support requires unfolding and supporting the support plates 7 on the mounting base 4 and the connecting base 5 in sequence, and supporting the uppermost support plate 7 in sequence from the bottom to the top.

[0057] This invention, by setting up a mounting base 4 and multiple connecting bases 5, allows the robotic arm 1 and welding unit 2 to be disassembled and assembled as a whole, enabling them to be installed and used in different locations. The multiple connecting bases 5 allow for the selection of different numbers of connecting bases 5 for installation according to actual usage conditions, thereby selecting different installation heights for the robotic arm 1 as a whole, which improves the applicability of the welding robot and enables it to adapt to welding work on different production lines. At the same time, the use of a foldable support plate 7 to unfold and be used as a welding table meets the needs of the welding robot in special circumstances, further improving the applicability of the welding robot, and the support plate 7 can be folded and stored without the need for additional separate handling equipment.

[0058] Example 2

[0059] To facilitate cleaning, maintain the working environment, and prevent welding slag and fumes from flying during welding robot operation, a drive unit 9 and an adsorption unit 8 are installed inside the receiving cavity 6, located on the upper end of the support plate 7. The drive unit 9 can control the adsorption unit 8 to move closer to or further away from the welding area, and the adsorption unit 8 is used to adsorb welding slag and fumes in the welding area. The drive unit 9, as the driving component that moves the adsorption unit 8 in and out of the receiving cavity, is configured as a lead screw 91, a screw sleeve 92, a motor 93, and a connecting plate 94. The lead screw 91 is rotatably mounted in the receiving cavity via bearings. Inside cavity 6, at the top, motor 93 is installed on one side of lead screw 91 and connected to one end of lead screw 91. Lead screw 91 is rotated under the control of motor 93, which is set as stepper motor 93. Screw sleeve 92 is sleeved on the outside of lead screw 91 and threadedly connected to lead screw 91. Connecting plate 94 connects screw sleeve 92 and adsorption unit 8, fixing screw sleeve 92 and adsorption unit 8 so that screw sleeve 92 and adsorption unit 8 are linked. During operation, motor 93 drives lead screw 91 to rotate, controlling screw sleeve 92, connecting plate 94 and adsorption unit 8 to move from the receiving cavity 6 to the outside of connecting seat 5, so that adsorption unit 8 is close to the welding workpiece.

[0060] To ensure sufficient displacement and allow the adsorption end of the adsorption unit 8 to move to the welding workpiece, the adsorption unit 8 is configured as a sliding block 81, an electric telescopic rod 82, and an adsorption element. A horizontal slide rail is installed on the inner wall of the receiving cavity 6. The two sides of the sliding block 81 are embedded in the slide rail and slide within the receiving cavity 6. The driving unit 9 is connected to the sliding block 81 and controls its movement. The sliding block 81 moves within the receiving cavity 6 in coordination with the slide rail, ensuring stable movement. A receiving groove 83 is provided on the side of the sliding block 81 facing the welding workpiece. An adsorption element is placed within the receiving groove 83. The electric telescopic rod 82 is mounted on the sliding block 81 and connected to the adsorption element, controlling the adsorption element to enter and exit the receiving groove 83. The electric telescopic rod 82 drives the adsorption element to move towards the welding workpiece. The dual movement of the driving unit 9 and the electric telescopic rod 82 ensures that the adsorption element can stably move to the welding workpiece for adsorption.

[0061] To improve airflow utilization, avoid pollutant emissions, and prevent welding fumes from overflowing to the sides and polluting the environment, the adsorption component is improved. Specifically, the adsorption component is configured as an adsorption frame 84, an adsorption port 851, an adsorption channel 852, and a jet nozzle 853. The adsorption frame 84 has two adsorption plates 85. When the adsorption frame 84 is close to the workpiece to be welded, the two adsorption plates 85 are located on both sides of the workpiece, with the workpiece located inside the adsorption frame 84. The adsorption channel 852 is opened inside the adsorption plates 85, and the adsorption port 851 is opened on the side of the adsorption plate 85 closest to the workpiece to be welded. Specifically, the adsorption port 851 is configured with openings in some parts of the adsorption plate 85, and an opening plate is snapped onto each opening. The adsorption ports 851 are evenly distributed on the opening plate. This configuration facilitates cleaning when the adsorption ports 851 become blocked. Replacement is convenient, and cleaning and maintenance of the adsorption channel 852 are also possible. The jet head 853 is installed on the adsorption plate 85 and is located on one side of the adsorption port 851, communicating with the adsorption channel 852. Both the adsorption port 851 and the jet head 853 are connected to the adsorption channel 852. The jet heads 853 on the two adsorption plates 85 are centrally symmetrically arranged with the welding workpiece as the center, so that the two jet heads 853 form two air curtains with opposite flow directions when blowing air. The output end of the jet head 853 is set to two, one for forming an air curtain, and the other is tilted towards the welding workpiece to assist welding fumes in entering the adsorption port 851. A fan 854 is provided in the adsorption channel 852. The fan 854 is used to drive the airflow to enter from the adsorption port 851 and exit from the jet head 853. A filter element 86 is provided in the adsorption channel 852.

[0062] The specific airflow direction is as follows: the gas ejected from the jet nozzle 853 on one adsorption plate 85 enters the adsorption channel 852 through the adsorption port 851 on another adsorption plate 85 and is filtered by the filter element 86. The filtered airflow is ejected from the jet nozzle 853 on the adsorption plate 85 to the other adsorption plate 85. Therefore, the airflow forms a loop in the welding area and flows in a loop.

[0063] To ensure the filtration effect within the adsorption channel 852 and facilitate the replacement of the filter element 86, the adsorption plate 85 has an installation hole 855 communicating with the adsorption channel 852. The filter element 86 is detachably installed in the installation hole 855, with one end inserted into the adsorption channel 852. The fan 854 is also installed inside the adsorption channel 852 through the installation hole 855. The filter element 86 includes a connecting frame 861 and a filter element 862. The connecting frame 861 has an external thread, and the installation hole 855 has an internal thread that mates with the external thread. The connecting frame 861 is threaded into the installation hole 855. The filter element 862 is installed inside the connecting frame 861. The filter element 862 includes one or more of the following: polyester filter cartridge, polyester fiber filter cartridge, glass fiber filter cartridge, polypropylene filter cartridge, and polytetrafluoroethylene filter cartridge. The connecting frame 861 has holes for airflow to pass through, allowing the gas to pass through for filtration and form a loop. The surface of the filter element 862 is honeycomb-shaped for adsorption and storage of filtered welding slag.

[0064] In this embodiment, by setting an adsorption unit 8 in the receiving cavity 6, and then moving the adsorption unit 8 to the welding workpiece when in use, the adsorption unit 8 can be effectively stored without occupying external space and avoiding interference with the normal operation of the robotic arm 1. At the same time, the use of an airflow forming loop for circulating cleaning can prevent the discharge of polluting gases, and an air curtain is formed on the side of the welding workpiece to prevent welding fumes from overflowing from the side and affecting the working environment.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
