[0034] The bracket welding workstation provided by the utility model comprises a workbench, a first storage position, a second storage position, a third storage position, a handling robot, a first welding robot, a second welding robot and a clamping device.

[0042] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] like Figure 1 As shown, in this embodiment, a bracket welding workstation is provided, including a workbench 1, a first storage position 21, a second storage position 22, a third storage position 23, a handling robot 3, a first welding robot 4, a second welding robot 5 and a clamping device 6.

[0047] The first storage position 21, the second storage position 22 and the third storage position 23 are located near the workbench 1. The first storage position 21 is used to store the flange plate, the second storage position 22 is used to store the web plate, and the third storage position 23 is used to store the finished welded parts. For example, the first storage position 21, the second storage position 22, and the third storage position 23 can be as follows: Figure 1 The layout setting in the embodiment is conducive to the pick-and-place range of the handling robot 3 covering the first storage position 21, the second storage position 22, the third storage position 23 and the workbench, so as to facilitate the transfer of materials between the above areas, and the materials may include flange plates, web plates, semi-finished welded parts and finished welded parts. Of course, the above storage positions can also be flexibly set according to actual conditions, and the above setting positions are for example.

[0048] The handling robot 3 is arranged near the workbench 1, and is suitable for handling materials between the first storage position 21, the second storage position 22, the third storage position 23 and the workbench 1. The handling robot 3 may be a movable robot, which can move to the positions of the various storage positions, and take out or put back the corresponding materials. Of course, when the first storage position 21, the second storage position 22, the third storage position 23 and the workbench 1 are close to each other, the handling robot 3 may also select a robot that does not have a mobile function but only has a steering and clamping function. The handling robot 3 may complete the picking and placing work by clamping, or by adsorption. Since the flange plate and the web are made of steel, the handling robot 3 may use an electromagnet to complete the adsorption and picking and placing work. The handling robot 3 may have a collection device for scanning and identifying the workpiece, and for subsequent position calibration.

[0049] The first welding robot 4 is movably arranged in a first direction of the workbench 1, and is suitable for moving toward or away from the workbench 1, and welding the workpiece located on the workbench 1 in the first direction. After the web and flange plate correction work is completed, the first welding robot 4 can weld the weld between the web and flange plates in the first direction. Before welding, the first welding robot 4 can identify the weld by line laser scanning, and then fix the weld by segmented spot welding.

[0050] The second welding robot 5 is movably arranged in a second direction of the workbench 1 opposite to the first direction, and is suitable for moving in a direction close to or away from the workbench, and welding the workpiece located on the workbench 1 in the second direction. After the web and flange plate correction work is completed, the second welding robot 5 can weld the weld between the web and flange plates in the second direction. Before welding, the second welding robot 5 can identify the weld by line laser scanning, and then fix the weld by segmented spot welding.

[0051] The clamping device 6 is arranged near the workbench 1 and is suitable for clamping and flipping the workpiece on the workbench. The clamping device 6 is mainly used to clamp and flip the semi-finished welded part. This is due to the requirements of the welding process. The semi-finished welded part is a T-shaped structural part. The unwelded side of the web of the semi-finished welded part faces upward, which is not conducive to welding the second flange plate to the web. Therefore, the second flange plate is placed on the workbench 1, the semi-finished welded part is flipped 180°, and the web is docked at the center position of the flange plate placed on the workbench 1. After that, the first welding robot 4 and the second welding robot 5 can continue to weld the welding positions of the web and the flange plate according to the above-mentioned welding method, thereby obtaining a finished welded part.

[0052] For example, the workbench 1 is placed on a work surface, which may be the ground, and the workbench 1 is used to carry materials, which may include flange plates, web plates, and semi-finished workpieces. The first handling robot 3 can carry the flange plates and web plates to the workbench, and transfer the finished welded parts out of the workbench 1. The first welding robot 4 and the second welding robot 5 can weld the materials on opposite sides of the workbench 1. The clamping device 6 can be turned over after welding the flange plates and web plates.

[0053] Specifically, the handling robot 3 is located between the workbench 1, the first storage position 21, the second storage position 22 and the third storage position 23. The handling robot 3 can transport the flange plate on the first storage position 21 to the workbench 1, and correct the position and angle of the flange plate. Then, the web plate on the second storage position 22 is transported to the workbench 1, and the web plate is kept aligned with the center position of the flange plate and maintained at 90° perpendicular to the flange plate. Then, the first welding robot 4 and the second welding robot 5 move to a position close to the workbench 1, and the first welding robot 4 and the second welding robot 5 identify the welds of the web plate and the flange plate, and perform segmented spot welding to fix them. After welding is completed, they return to their original positions, thereby obtaining a semi-finished welded part. The clamping device 6 clamps and drives the semi-finished welded part off the workbench 1. The handling robot 3 carries the flange plate on the first storage position 21 to the workbench 1, and corrects the position and angle of the flange plate. The clamping device 6 flips the semi-finished welded part 180° and places it at the center of the flange plate, and keeps the web plate and the center of the flange plate perpendicular to each other at 90°. The first welding robot 4 and the second welding robot 5 move to a position close to the workbench 1 again. The first welding robot 4 and the second welding robot 5 identify the weld seams of the web plate and the flange plate again, and perform segmented spot welding and fixation. After welding, they return to their original positions to obtain a finished welded part, which is the bracket. The clamping device 6 cancels the clamping state, and the handling robot 2 takes the finished welded part out of the workbench 1 and places it in the third storage position 23 for storage. In this way, the welding work of a finished welded part is completed.

[0054] The bracket welding workstation provided by the utility model can completely rely on the cooperation of the first handling robot 3, the first welding robot 4, the second welding robot 5 and the clamping device 6 to complete the welding work of the bracket. In this process, no manual calibration, welding or other lifting equipment is required to participate in the handling, which reduces the use of human resources, simplifies the operation difficulty, and improves the production efficiency. It can also be applicable to the assembly and welding of various types of bracket structural parts.

[0055] In addition, the first welding robot 4 and the second welding robot 5 can weld the weld between the web and the flange plate at the same time, which reduces the welding time and improves the work efficiency.

[0056] like Figure 1 As shown, in this embodiment, the bracket welding workstation includes a first guide rail 41 and a second guide rail 51 respectively arranged in the first direction and the second direction of the workbench 1, the first guide rail 41 extends from the edge position of the workbench 1 to the first direction, and the second guide rail 51 extends from the edge position of the workbench 1 to the second direction. The first welding robot 4 includes a first walking chassis that slidably cooperates with the first guide rail 41, and the second welding robot 5 includes a second walking chassis that slidably cooperates with the second guide rail 51.

[0057] When welding is required, the first traveling chassis drives the first welding robot to move along the first guide rail 41 to a position close to the workbench 1, and the second traveling chassis drives the second welding robot 5 to move along the second guide rail 51 to a position close to the workbench 1. After welding is completed, the first traveling chassis drives the first welding robot to move along the first guide rail 41 to a position away from the workbench 1, and the second traveling chassis drives the second welding robot 5 to move along the second guide rail 51 to a position away from the workbench 1.

[0058] The first welding robot 4 and the second welding robot 5 are away from the workbench 1 when not performing welding work, which is beneficial to avoid motion interference between the transport robot 3 and the first welding robot 4 and / or the second welding robot 5 when performing the transport action, thereby avoiding equipment damage caused by collision.

[0059] The first walking chassis and the second walking chassis may be composed of a driving motor, a transmission structure, a driving wheel set and a transmission wheel set. The driving wheel set and the transmission wheel set cooperate with the first guide rail 41 and the second guide rail 51 to drive the first welding robot 4 and the second welding robot 5 to move, and can improve the stability of the movement of the first welding robot 4 and the second welding robot 5.

[0060] like Figure 1As shown, in this embodiment, the first welding robot 4 includes: a first frame, a first mechanical arm, and a first welding gun. The first frame is rotatably arranged on the first walking chassis through a first slewing bearing. The first mechanical arm is movably connected to the first frame. The first welding gun is arranged at the end of the first mechanical arm. The first frame is arranged on the first walking chassis through a slewing bearing as the main supporting component, so that the first frame can rotate in a clockwise or counterclockwise direction in a horizontal plane to adjust the position of the first mechanical arm. The first mechanical arm can have a plurality of movable joints, thereby facilitating the adjustment of the posture of the first welding gun, thereby facilitating accurate welding of the welding point.

[0061] like Figure 1 As shown, in this embodiment, the second welding robot 5 includes: a second frame, a second mechanical arm and a second welding gun. The second frame is rotatably arranged on the second walking chassis through a second slewing bearing. The second mechanical arm is movably connected to the second frame. The second welding gun is arranged at the end of the second mechanical arm. The second frame is arranged on the second walking chassis through a slewing bearing as a main supporting component, so that the second frame can rotate in a clockwise or counterclockwise direction in a horizontal plane to adjust the position of the second mechanical arm. The second mechanical arm can have a plurality of movable joints, thereby facilitating the adjustment of the posture of the second welding gun, thereby facilitating accurate welding of the welding point.

[0062] like Figure 1 As shown, in this embodiment, the handling robot includes: a chassis assembly, a third frame, a third mechanical arm and a handling assembly. The chassis assembly can have a hub structure or a bracket placed on the ground, which can be flexibly selected according to the actual working conditions of the handling robot. The third frame is rotatably arranged on the chassis assembly through a third slewing bearing. The third frame is arranged on the third walking chassis as the main supporting component through a slewing bearing, so that the third frame can rotate in a clockwise or counterclockwise direction in a horizontal plane to adjust the position of the third mechanical arm. The third mechanical arm is movably connected to the third frame. The third mechanical arm can have multiple movable joints, which facilitates the adjustment of the posture of the third welding gun. The handling assembly is arranged at the end of the third mechanical arm, and is suitable for driving the material to move between the first storage position 21, the second storage position 22, the third storage position 23 and the workbench 1 by adsorption or clamping. The handling assembly can be a structure such as a manipulator, a clamp or an electromagnetic suction cup for picking up and placing plate-shaped steel.

[0063] like Figure 1As shown, in this embodiment, a third guide rail 61 is provided in the third direction of the workbench 1, and the third guide rail 61 extends from the edge of the workbench 1 to the direction away from the workbench 1. The third direction has an angle with the first direction and the second direction. For example, the third direction can be perpendicular to the first direction and the second direction. In addition, the handling robot can be arranged in a fourth direction opposite to the third direction, so that the handling robot 3, the clamping device 6, the first welding robot 4 and the second welding robot 5 can be respectively located in the front, back, left and right directions of the workbench 1 to avoid interference caused by too close distance. The clamping device 6 is slidably arranged on the third guide rail 61 through a moving mechanism, and the moving mechanism is suitable for driving the clamping device 6 to move in a direction close to or away from the workbench. After the clamping device 6 clamps the semi-finished welded part, it can move along the third guide rail 61 in a direction away from the workbench 1, driving the semi-finished welded part to leave the workbench 1, so as to facilitate the handling robot 2 to place the second flange plate on the workbench 1, and then move along the third guide rail 61 in a direction close to the workbench 1, so as to align the semi-finished welded part with the second flange plate.

[0064] like Figure 1 As shown, in this embodiment, the clamping device includes: a frame and a clamping assembly. The frame is installed on the moving mechanism. The clamping assembly is arranged on the frame and faces the workbench through a lifting mechanism, and the lifting mechanism is suitable for driving the clamping assembly to move in the height direction. After the clamping assembly clamps the semi-finished welded part, the lifting mechanism can drive the clamping assembly to move upward to a certain height, and then the moving mechanism drives the frame to move away from the workbench 1 along the third guide rail 61, so as to avoid friction between the semi-finished welded part and the workbench 1, causing unnecessary wear. In the subsequent process of moving the semi-finished welded part to the workbench 1, the lifting mechanism can drive the clamping assembly to move up and down to realize the alignment of the web and the flange plate.

[0065] like Figure 1 As shown, in this embodiment, the clamping assembly includes a clamping claw and a mounting seat, the mounting seat is mounted on the lifting mechanism, and the clamping claw is rotatably arranged on the mounting seat.

The first clamping jaw and the second clamping jaw can realize the clamping action and the releasing action when they approach or move away from each other, and the guide seat is rotatably installed on the mounting seat so that the first clamping jaw and the second clamping jaw drive the semi-finished welded part to turn 180°.

[0067] like Figure 1 As shown, in this embodiment, the bracket welding workstation also includes an operating table 7, and the operating table 7 is connected to the handling robot 3, the first welding robot 4, the second welding robot 5 and the clamping device 6 through wired communication or wireless communication.
