Description

Technical Field

[0001] This invention relates to the field of loader bucket technology, and in particular to a workstation and method for welding loader buckets. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] The loader bucket boom is a curved structural component made of steel plates. Because steel plates are standard parts, two steel plates are usually welded together to form a large plate, which is then bent into a U-shape to form the basic structure of the boom. Currently, the welding of the two steel plates is usually done manually. The length of the boom steel plates is usually around 1.7-2.1 meters, with one boom steel plate being wider than 0.6 meters and the other wider than 1.2 meters. Manual welding is labor-intensive and inefficient. Moreover, the boom steel plates are not positioned during the welding process, which can easily cause deviation during manual welding, thus affecting the welding accuracy and quality of the boom steel plates. In addition, a pin connector is usually installed on the outside of the loader boom. The pin connector includes a pin seat and a flange. The flange is placed on one side of the pin seat. The pin connector is used for subsequent connection with the boom to connect with the loader boom in subsequent work. The connection between the pin seat and the flange also needs to be welded manually. There is also the problem of no positioning during the welding process of the pin connector, and the welding of round parts is difficult. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a workstation for welding loader buckets, solving the problems of high labor intensity, low welding efficiency, and high safety risks associated with manual assembly welding.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: A workstation for welding loader buckets, comprising: Welding robots are capable of moving linearly along the Y-axis. The first worktable is placed on one side of the welding robot. The first worktable includes a support frame that can support at least two boom steel plates. The splice seam of the boom steel plates is set along the Y direction. The support frame is equipped with an electromagnet to attract the boom steel plates. First positioning components are respectively set on both sides of the support frame. The first positioning components position the boom steel plates from the Y direction. The support frame is connected to a mobile power source. The mobile power source moves to drive the support frame to move along the X direction to approach the welding robot, so that the splice seam of the boom steel plates is within the working area of ​​the welding robot.

[0006] As described above, a loader bucket welding workstation further includes a second workbench. The second workbench is located on the side of the welding robot away from the first workbench. The second workbench is equipped with at least two sets of second positioning components to position the loader pin connectors respectively. In order to make full use of the welding robot for automatic welding without the need for manual welding, the second workbench is located on one side of the welding robot. During the loading and unloading process after the boom steel plate welding operation is completed, the welding robot can weld the loader pin connectors at the second workbench, which further helps to improve work efficiency.

[0007] As described above, in a loader bucket welding workstation, the second positioning component includes a quick-change positioning block and a second positioning pin. The quick-change positioning block positions the circular hole of the loader pin connector. The quick-change positioning block is detachably installed on the surface of the second worktable. The bottom of the quick-change positioning block is inserted into the recess of the second worktable. The second positioning pin limits the loader pin connector from the recess of the loader pin connector. The quick-change positioning block and the second positioning pin cooperate to position the loader pin connector.

[0008] As described above, in a loader bucket welding workstation, a bottom positioning component is provided at the bottom of the second worktable, a support pipe is provided on the ground, a positioning hole is provided at the support pipe, and the bottom positioning component is provided with at least two elastic protrusions. The elastic protrusions of the bottom positioning component cooperate with the positioning holes to achieve positioning of the second worktable.

[0009] As described above, in a loader bucket welding workstation, the bottom side of the second workbench has a set width, and the conveying trolley can move to the bottom side of the second workbench to load or unload the loader pin connecting parts. The transport trolley and the welding robot are connected via remote communication.

[0010] As described above, a workstation for welding loader buckets includes two working panels on the top of the support frame to support the boom steel plates. The two working panels are spaced apart, and the width of the working panels is smaller than the width of the two boom steel plates after splicing. An electromagnet is installed on the working panel to attract the boom steel plates.

[0011] As described above, in a loader bucket welding workstation, the first positioning component includes first positioning pins located on both sides of the working panel, the distance between the two first positioning pins being adapted to the length of the bucket arm steel plate, and at least one of the first positioning pins being movable relative to the working panel.

[0012] As described above, a workstation for welding loader buckets includes multiple mobile power sources arranged in parallel. The fixed end of each mobile power source is fixed to the ground, and the telescopic end of the mobile power source is connected to the support frame. A ground rail is provided on the ground, and a roller is provided at the bottom of the support frame, allowing the roller to move along the ground rail.

[0013] As described above, a workstation for welding loader buckets includes a welding robot and a fence structure with a set length on the side of the first workbench. The welding robot is placed inside a dust removal room.

[0014] Secondly, the present invention also provides a method for welding a loader bucket, wherein welding is performed using a loader bucket welding workstation, and includes the following: The mobile power source drives the support frame to move away from the welding robot. The boom steel plate is placed on the first worktable. The splice seam of the boom steel plate is set along the Y direction. The support frame is equipped with an electromagnet to attract the boom steel plate. Then, the mobile power source drives the support frame to move the boom steel plate into the working area of ​​the welding robot. The welding robot welds two bucket arm steel plates and moves along the Y direction until the joint of the bucket arm steel plates is welded.

[0015] The beneficial effects of the present invention are as follows: This invention provides a workstation equipped with a welding robot capable of linear movement along the Y-axis. The first worktable includes a support frame supporting two boom plates. Electromagnets are installed on the support frame to stably attract the boom plates, ensuring their position. First positioning components are installed on both sides of the support frame to position the boom plates along the Y-axis, preventing deviation during welding and ensuring welding accuracy. Considering the welding robot occupies space, the support frame can move along the X-axis for easier loading. This movement allows workers to load materials from the side furthest from the welding robot, ensuring space for loading and unloading larger boom plates. After loading, the support frame moves the boom plates closer to the welding robot for welding, thus reducing manual labor intensity and ensuring welding accuracy and quality.

[0026] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. As described in the background section, welding of the bucket arm in the prior art requires manual welding, which involves a large amount of welding work and the lack of positioning affects the welding quality. In order to solve the above technical problems, this invention proposes a workstation for welding loader buckets.

[0028] Example 1 In a typical embodiment of the present invention, reference is made to Figure 1 As shown, a workstation for welding loader buckets includes: Welding robot 3 is capable of moving linearly along the Y direction; The first workbench 7 is placed on one side of the welding robot 3. The first workbench 7 includes a support frame 10, which can support at least two boom steel plates 1. The splice seam of the boom steel plates 1 is set along the Y direction. The support frame 10 is equipped with an electromagnet 16 to attract the boom steel plates 1. The two sides of the support frame 10 are respectively equipped with first positioning components. The first positioning components position the boom steel plates 1 from the Y direction. The support frame 10 is connected to a mobile power source 8. The mobile power source 8 moves to drive the support frame 10 to move along the X direction to approach the welding robot 3, so that the splice seam of the boom steel plates 1 is within the working area of ​​the welding robot 3.

[0029] The workstation provided in this embodiment has a support frame 10 that can support two bucket arm steel plates 1. The support frame 10 is equipped with an electromagnet 16 to stably attract the bucket arm steel plates 1 and ensure the position of the bucket arm steel plates 1. First positioning components are respectively set on both sides of the support frame 10 to position the bucket arm steel plates 1 from the Y direction to avoid the bucket arm steel plates 1 from deviating during the welding process and to ensure the welding accuracy. The support frame 10 is movable along the X direction, thus providing space for loading and unloading of larger bucket arm steel plates 1 (by crane). During loading and unloading, the bucket arm steel plates 1 are moved to the side away from the welding robot 3, thus avoiding collisions with the welding robot 3 during transportation and ensuring the safety of the operation.

[0030] In this embodiment, reference Figure 3 As shown, the support frame 10 is formed by connecting horizontal and vertical bars. The support frame 10 is a steel frame to ensure structural strength. (Refer to...) Figure 4As shown, the support frame 10 has two working panels 14 on top to support the bucket arm steel plate 1. The two working panels 14 are spaced apart to facilitate the loading of larger bucket arm steel plates 1. The width of the working panels 14 is smaller than the width of the two bucket arm steel plates 1 after splicing, which is also to facilitate the loading and unloading of the bucket arm steel plates 1. The working panels 14 have grooves, and electromagnets 16 are installed in the grooves to attract the bucket arm steel plates 1. The electromagnets 16 can be switch magnets. The switch magnets are located on both sides of the splice seam of the two bucket arm steel plates 1. The switch magnets are connected to the control unit, which is a PLC controller or other type of controller. The control unit controls the opening and closing of the switch magnets. First, the bucket arm steel plate is loaded. After loading is completed, the control unit is manually operated to open the switch magnets, thereby achieving the attraction of the bucket arm steel plate and ensuring the stability of the bucket arm steel plate position during welding, avoiding deviation problems.

[0031] In this embodiment, the mobile power source includes multiple parallel locations, specifically four locations. Two mobile power sources 8 drive one support, and the other two mobile power sources drive the other support. The fixed end of each mobile power source 8 is fixed to the ground, and the telescopic end of the mobile power source 8 is connected to the support frame 10. A ground rail 11 is provided on the ground, and a roller 25 is provided at the bottom of the support frame. The roller 25 can move along the ground rail 11. The ground rail 11 corresponds one-to-one with the mobile power source 8, and the mobile power source 8 and the ground rail 11 are parallel to each other. The mobile power source 8 is connected to the control unit, which controls the movement of the mobile power source. The mobile power source 8 can push the entire support frame 10 to reciprocate along the ground rail in the X direction. The mobile power source 8 is specifically a drive cylinder. A connecting block is provided at the end of the drive cylinder. Fasteners such as multiple bolts pass through the support frame 10 and the connecting block and are locked by nuts. The cylinder body of the drive cylinder is fixed to the ground by a vertical frame.

[0032] In addition, the ground rail 11 is set along the X direction and is fixed to the ground by the support block 13. The support block 13 is fixed to the ground and is set perpendicular to the ground rail 11. The two sides of the support block 13 extend beyond the width direction of the ground rail 11. Extensions are provided on both sides of the ground rail 11. One side of the clamping block is connected to the support block 13 by bolts, and the other side of the clamping block is placed above the extension. The clamping bolt passes through the clamping block and abuts against the extension of the ground rail 11. The levelness of the ground rail can be adjusted by adjusting the clamping block in conjunction with a level. Limiting protrusions 15 are provided at both ends of the ground rail 11 to limit the rolling wheel 25. It is easy to understand that the ground rail 11 can also be replaced with other rails with grooves, and the roller 25 can move along the length of the rail.

[0033] Additionally, refer to Figure 2As shown, a moving rail 22 is provided at the bottom of the welding robot 3, and the welding robot moves along the moving rail 22. A welding torch 24 is provided at the end of the welding robot 3. A torch cleaning mechanism 21 is provided on the side of the welding robot 3. The torch cleaning mechanism 21 is used to clean the welding torch of the welding robot 3. The torch cleaning mechanism 21 is located next to the first workbench 7. A wire hopper placement platform 23 is also provided on the side of the welding robot 3 for placing the welding wire.

[0034] To facilitate processing and manufacturing, the support frame 10 includes two supports, each supporting a working panel 14. The sum of the gaps between the two working panels 14 and the two supports is greater than the length of the boom steel plate 1, providing space for the positioning of the boom steel plate 1 and also enabling support for boom steel plates 1 of different sizes. The two supports are connected to ensure integrity, but the two working panels 14 are not connected. The space between the two working panels can be used to place the hands of workers or hoisting equipment to facilitate the loading and unloading of the boom steel plate 1.

[0035] It should be noted that the first positioning component includes first positioning pins 12 located on both sides of the working panel 14. The distance between the two first positioning pins 12 is adapted to the length of the bucket arm steel plate 1. At least one first positioning pin 12 is movable relative to the working panel. The first positioning pin 12 is specifically a magnetic post. The first positioning pin can be attracted to the working panel 14 and can be quickly separated from the working panel. The first positioning pins 12 are placed on both sides of the length direction of the bucket arm steel plate 1. In this way, the bucket arm steel plate is positioned in the Y direction from both sides of the bucket arm steel plate 1, which helps to ensure the welding accuracy. After welding is completed, the first positioning pins 12 are magnetic posts and can also be relatively quickly detached from the working panel 14.

[0036] It is easy to understand that the welding robot 3 adopts the existing welding robot. The welding robot 3 can rotate and move along the Y direction. The welding robot 3 and the first workbench 7 are equipped with fence structure 5 on their sides. The fence structure 5 has a set length and surrounds the welding robot and the first workbench 7 in a set area to prevent workers from suddenly entering and to ensure the safety of the operation. The welding robot 3 is placed in a dust removal room 4. The dust removal room 4 is used to remove the dust generated by the welding robot 3 during the welding process. The dust removal room 4 covers the second workbench 2, the welding robot 3 and the first workbench 7 to avoid affecting the loading and unloading of the bucket arm steel plate 1. That is to say, under the drive of the mobile power source 8, the splice seam of the two bucket arm steel plates 1 can be sent into the dust removal room 4. The dust removal room 4 is equipped with a smoke exhaust fan, which is connected to the outside of the factory for exhaust.

[0037] In addition, the workstation also includes a second workbench 2, see reference. Figure 5As shown, the second workbench 2 is placed on the side of the welding robot 3 away from the first workbench 7. The second workbench 2 is equipped with at least two sets of second positioning components to position the loader pin connector 9 respectively. In order to make full use of the welding robot 3 for automatic welding without manual welding, the second workbench 2 is placed on one side of the welding robot 3. During the loading and unloading process after the welding of the boom steel plate 1 is completed, the welding robot 3 can weld the loader pin connector 9 at the second workbench 2, which is conducive to improving work efficiency.

[0038] Specifically, the second workbench 2 is also formed by welding a horizontal frame and a vertical frame. A support panel is provided on the surface of the second workbench 2, which is used to support the pin connector.

[0039] refer to Figure 6 As shown, the second positioning component includes a quick-change positioning block 18 and a second positioning pin 17. The quick-change positioning block 18 positions the circular hole of the loader pin connector 9. The quick-change positioning block 18 is detachably installed on the surface of the second workbench. The bottom of the quick-change positioning block 18 is inserted into the recess of the second workbench 2. Because the pin connector 9 has a recess, the position of the second positioning pin 17 can be predetermined so that the pin connector can be quickly positioned on the second workbench 2. The second positioning pin 17 limits the loader pin connector 9 from the recess of the loader pin connector. The second positioning pin 17 can be a magnetic post or be inserted into the support panel of the second workbench. The quick-change positioning block 18 and the second positioning pin 17 cooperate to position the loader pin connector 9 so that the welding robot can weld and fix the flange to one side of the pin seat.

[0040] For details, please refer to Figure 7 As shown, the quick-change positioning block 18 is a cylindrical block. The bottom of the quick-change positioning block 18 is provided with a positioning protrusion 20. The cross-section of the positioning protrusion 20 is circular. The positioning protrusion 20 can be inserted into the recess of the support plane of the second worktable 2. The quick-change positioning block 18 is provided with an opening in the center. The bolt passes through the opening and is detachably connected to the second worktable 2. For different sizes of pin shaft connectors 9, quick-change positioning blocks 18 of different sizes can be replaced to achieve positioning of pin shaft connectors 9 of different sizes. It is easy to understand that the bottom of the second workbench 2 is equipped with a bottom positioning component, and a support tube 19 is set on the ground. There are two support tubes 19 (square tubes) along the X direction. The positions of the two support tubes 19 correspond to the positions on the bottom side of the second workbench. The support tubes 19 are fixed to the ground and positioning holes are set at the support tubes 19. The bottom positioning component is equipped with at least two elastic protrusions. The bottom of the second workbench 2 is equipped with mounting holes, and elastic protrusions are set at the mounting holes. The elastic protrusions include protrusions and are installed at the mounting holes by springs. When the conveyor trolley is loading, it moves along the X direction to move the second workbench 2 along the length of the support tube. After the second workbench 2 is in place, the elastic protrusions of the bottom positioning component cooperate with the positioning holes, that is, the elastic protrusions are engaged in the positioning holes to achieve the positioning of the second workbench. The conveyor trolley stops moving and waits for the welding work to be completed. After the welding is completed, the conveyor trolley drives the second workbench to move. Because the elastic protrusions are elastic, they will not hinder the second workbench from detaching from the support tube.

[0041] It should be explained that, in order to further realize automated operation and improve work efficiency, the bottom side of the second workbench has a set width. The conveying trolley 6, such as the existing AGV (Automated Guided Vehicle) conveying trolley, can move to the bottom side of the second workbench to drive the overall movement of the second workbench, so as to realize the automatic loading or unloading of the loader pin shaft connecting parts without manual loading, thus ensuring the safety of operation. It is easy to understand that the conveyor trolley 6 is remotely connected to the welding robot 3. The control unit controls the movement of the mobile power source. After the conveyor trolley 6 finishes loading, it sends a signal to the welding robot 3. After the welding robot 3 finishes its work, it sends a signal to the conveyor trolley 6 to unload the material.

[0042] The workstation provided in this embodiment uses a welding robot 3 to weld the boom steel plate 1, eliminating the need for manual welding and improving work efficiency. The first worktable 7 can move in the X-axis, facilitating the loading and unloading of the boom steel plate 1. Even when loading larger boom steel plates 1, moving them closer to the welding robot 3 avoids interference. Since loading and unloading larger boom steel plates 1 takes a considerable amount of time, this time is utilized to further improve the processing efficiency of the loader bucket. During this time, the welding robot 3 can weld the pin connector 9 on the other side of the first worktable 7, making full use of time and space while ensuring safety.

[0043] Example 2 This embodiment discloses a loader bucket welding method, which uses a loader bucket welding workstation as described in Embodiment 1 for welding, and includes the following: The mobile power source 8 drives the support frame 10 to move away from the welding robot 3; The boom steel plate 1 is placed on the first workbench 7. The splice seam of the boom steel plate 1 is set along the Y direction. The support frame 10 is equipped with an electromagnet to attract the boom steel plate 1 (the magnet is turned on to attract the boom steel plate). Then, the mobile power source 8 drives the support frame 10 to move the boom steel plate 1 to the working area of ​​the welding robot 3. Welding robot 3 welds two bucket arm steel plates 1 and moves along the Y direction until the splice of bucket arm steel plates 1 is welded. The welded bucket arm steel plates are then unloaded and new bucket arm steel plates are loaded. During the welding process of the welding robot 3 welding the bucket arm steel plate 1, the pin connector 9 is placed on the second workbench 2 by the manual, and the quick-change positioning block 18 and the second positioning pin 17 are used to position it to ensure the stability of the pin connector 9 during the welding process. Alternatively, the AGV transport vehicle can transport the second workbench 2, which is already equipped with the pin connector 9, to the side of the welding robot 3 away from the first workbench 7. While the bucket arm steel plate 1 is being manually unloaded and loaded, the welding robot 3 is welding the pin seat and flange in the pin connector 9. Because the pin connector 9 is fixed, the welding robot can quickly fix the flange to the pin seat.

[0044] 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.
