Description

Technical Field

[0001] This utility model relates to the field of trailer beam welding technology, specifically, to an automated trailer beam welding equipment. Background Technology

[0002] In the trailer manufacturing industry, the welding of trailer beams currently mainly uses submerged arc semi-automatic welding machines. Operators need to observe the welding status in real time to adjust the welding posture and parameters accordingly. Welding is impossible when the workpiece has sharp bends, requiring manual re-welding. This results in high labor intensity and low efficiency. Furthermore, submerged arc welding requires the use of protective flux, which must be cleaned and recovered after welding, leading to a poor on-site working environment.

[0003] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an automated welding equipment for trailer beams. This invention can reduce the labor intensity of workers, reduce auxiliary working hours, improve production efficiency, improve product quality stability, and improve the working environment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an automated welding equipment for trailer beams, including a welding table, a gantry welding workstation, a beam tilting mechanism, several transmission roller conveyors, several beam clamping mechanisms, a welding station positioning and detection module, and a control system.

[0006] The welding tables are arranged in the left-right direction to provide a welding platform for the beam workpiece;

[0007] The gantry welding workstation includes a welding station gantry, a sliding table, a welding robot, and a line laser. The welding station gantry spans horizontally above the welding table. The sliding table moves back and forth on the top beam of the welding station gantry via a linear drive mechanism. The welding robot is fixedly mounted on the sliding table. The line laser is mounted on the sliding table via a lifting mechanism and a forward and backward movement mechanism. The welding robot follows the sliding table to move left and right to weld the beam workpiece. The line laser follows the sliding table to move left and right and automatically locates and tracks the weld seam under the action of the lifting mechanism and the forward and backward movement mechanism to guide the welding robot's work.

[0008] The welding robot moves back and forth on the top beam of the welding station gantry to weld the beam workpiece.

[0009] Line lasers are integrated into welding robots for automatic positioning and tracking of weld seams to guide the robot's work.

[0010] The beam flipping mechanism is located in the middle of the welding table and is used to flip the beam workpiece.

[0011] Each conveyor roller is spaced apart on the upper part of the welding table to convey the large beam workpiece to the welding station in the middle of the welding table.

[0012] Each beam clamping mechanism is spaced apart on the upper part of the welding table to clamp the beam workpiece.

[0013] The welding station positioning and detection module is set on the downstream side of the main beam workpiece on the welding table to detect whether the main beam workpiece has been transferred to the welding station.

[0014] The control system is connected to the welding robot, line laser, linear drive mechanism, lifting mechanism, forward and backward movement mechanism, beam tilting mechanism, conveyor roller conveyor, beam clamping mechanism, and welding station positioning and detection module for signal control.

[0015] Based on the above, the welding table is also equipped with a beam anti-deformation mechanism to reduce the welding deformation of the beam workpiece. The beam anti-deformation mechanism includes at least one anti-deformation cylinder and at least one pair of anti-deformation positioning blocks. The anti-deformation cylinder is arranged in the middle of the upper front side of the welding table in the front-back direction. The two pairs of anti-deformation positioning blocks are symmetrically arranged on the left and right sides of the upper rear side of the welding table about the anti-deformation cylinder. The control system is connected to the anti-deformation cylinder signal control.

[0016] Based on the above, a welding machine and a dust collector are installed on the upper part of the top beam of the welding station gantry, and the welding machine provides power to the welding robot.

[0017] Based on the above, it also includes an integrated dust cover, which is installed on the front and back sides of the welding table.

[0018] Based on the above, the welding station positioning and detection module is a laser beam sensor, and the control system is connected to the laser beam sensor signal control.

[0019] This invention has substantial features and advancements compared to existing technologies. Specifically, the line laser and welding robot are independently mounted on a sliding table. The sliding table moves back and forth on the welding station gantry via a linear drive mechanism. The line laser is mounted on the sliding table via a lifting mechanism and a forward and backward movement mechanism. Under the action of the lifting mechanism, the forward and backward movement mechanism, and the sliding table, the line laser can move along the X, Y, and Z axes. Therefore, even when the workpiece has sharp bends, the line laser can accurately locate and track the weld seam automatically. Guided by the line laser, the welding robot can automatically weld the sharp bends of the workpiece without manual re-welding, thus achieving fully automated welding of the workpiece. Furthermore, the workpiece can be transported to the welding station via various conveyor rollers on the welding table. The welding station positioning and detection module accurately positions the workpiece to the welding station, and the workpiece can be flipped by the workpiece flipping mechanism. The entire welding process has a high degree of automation, low labor intensity, and a single person can manage multiple automated welding devices for the trailer's workpiece simultaneously, reducing auxiliary time, improving production efficiency, and enhancing product quality stability. Meanwhile, the welding fumes can be collected and treated through the integrated dust hood and dust collector during the welding process, resulting in pollution-free operation and a clean and tidy overall environment.

[0029] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0030] Example 1

[0031] like Figures 1-8 As shown, the automated welding equipment for trailer beams includes a welding table 1, a gantry welding workstation, a beam tilting mechanism 2, several conveyor roller conveyors 3, several beam clamping mechanisms 4, a welding station positioning and detection module, and a control system.

[0032] Welding table 1 is arranged in the left-right direction to provide a welding platform for the main beam workpiece 13;

[0033] The gantry welding workstation includes a welding station gantry 5, a sliding table 14, a welding robot 6, and a line laser 7. The welding station gantry 5 spans horizontally above the welding table 1. The sliding table 14 moves back and forth on the top beam of the welding station gantry 5 via a linear drive mechanism.

[0034] The welding robot 6 is fixedly mounted on the slide table 14. The line laser 7 is mounted on the slide table 14 through the lifting mechanism 15 and the forward and backward moving mechanism 16. The welding robot 6 moves left and right with the slide table 14 to weld the beam workpiece. The line laser 7 moves left and right with the slide table 14 and automatically locates and tracks the weld seam under the action of the lifting mechanism 15 and the forward and backward moving mechanism 16 to guide the welding robot 6 to work.

[0035] The beam flipping mechanism 2 is located in the middle of the welding table 1 and is used to flip the beam workpiece 13.

[0036] Each conveyor roller 3 is spaced apart on the upper part of the welding table 1 to convey the beam workpiece 13 to the welding station in the middle of the welding table 1.

[0037] Each main beam clamping mechanism 4 is spaced apart on the upper part of the welding table 1 to clamp the main beam workpiece 13.

[0038] The welding station positioning and detection module is set on the downstream side of the incoming beam workpiece 13 on the welding table 1, and is used to detect whether the beam workpiece 13 has been transferred to the welding station.

[0039] The control system is connected to the welding robot 6, the line laser 7, the linear drive mechanism, the lifting mechanism, the forward and backward movement mechanism, the beam flipping mechanism 2, the conveyor roller 3, the beam clamping mechanism 4, and the welding station positioning and detection module for signal control.

[0040] In this embodiment, the welding table 1 is divided into three sections on the left and right, and the beam flipping mechanism 2 is provided between two adjacent welding table sections 1.

[0041] In this embodiment, the linear drive mechanism is a mechanism or linear module composed of a motor, gears, rack, guide rail, and slider. The lifting mechanism 15 is a linear module or a slide cylinder. The forward and backward movement mechanism 16 is also a mechanism or linear module composed of a motor, gears, rack, guide rail, and slider. The forward and backward movement mechanism 16 is mounted on the slide 14, the lifting mechanism 15 is mounted on the slider of the forward and backward movement mechanism 16, and the line laser 7 is mounted on the slider of the lifting mechanism 15. The forward and backward movement mechanism 16 can adjust the position of the line laser 7 in the forward and backward direction, and the lifting mechanism 15 can adjust the height position of the line laser 7.

[0042] Specifically, the welding table 1 is also equipped with a beam anti-deformation mechanism to reduce the welding deformation of the beam workpiece 13. The beam anti-deformation mechanism includes at least one anti-deformation cylinder 8 and at least one pair of anti-deformation positioning blocks 9. The anti-deformation cylinder 8 is arranged in the middle of the upper front side of the welding table 1 in the front-back direction. The two pairs of anti-deformation positioning blocks 9 are symmetrically arranged on the left and right sides of the upper rear side of the welding table 1 about the anti-deformation cylinder 8. The control system is connected to the anti-deformation cylinder 8 by signal control.

[0043] Specifically, the welding station positioning and detection module is a laser beam sensor 10, and the control system is connected to the laser beam sensor 10 for signal control.

[0044] The control system is a PLC controller.

[0045] The control system, the main beam tilting mechanism 2, the conveyor roller conveyor 3, the main beam clamping mechanism 4, the welding station gantry 5, the welding robot 6, the line laser 7, the linear drive mechanism, the lifting mechanism 15, the forward and backward movement mechanism 16, and the laser beam sensor 10 are all existing technologies, and their specific structures and working principles will not be described in detail.

[0046] During operation, the main beam workpiece 13 is transferred from the previous process to the welding station on the upper part of the welding table 1 via various conveyor rollers 3; after detection by the laser beam sensor 10, the control system receives the signal from the laser beam sensor 10 and controls each conveyor roller 3 to stop conveying; the main beam flipping mechanism 2 flips the main beam workpiece 13 180°; then the anti-deformation cylinder 8 presses the main beam workpiece 13 against the two pairs of anti-deformation positioning blocks 9, performing anti-deformation on the main beam workpiece 13; the main beam clamping mechanism 4 clamps the main beam to reduce angular deformation; at this time, the linear laser 7 follows the slide table 14 and moves left and right under the action of the linear drive mechanism, while simultaneously being lifted by the lifting mechanism 15 and... The lifting and lowering mechanism 16, along with the forward and backward movement, enables the line laser 7 to move along the X, Y, and Z axes. This allows the line laser 7 to accurately locate and track the weld seam even when the workpiece 13 has sharp bends. After locating the weld seam, the line laser 7 communicates the position point to the welding robot 6 via the control system. The control system then controls the welding robot 6 to follow the position point and move left and right along the top beam of the welding station gantry 5 to initiate arc welding. The robot 6 automatically welds based on the position point tracked in real time by the line laser 7. After welding, the welding robot 6 and the line laser 7 automatically return to the original position on the top beam of the welding station gantry 5 with the slide table. The entire welding process is highly automated, requiring less manual labor. A single person can manage multiple automated welding devices for the trailer beam simultaneously, reducing auxiliary time, increasing production efficiency, and improving product quality stability.

[0047] Multiple sets of this automated welding equipment for trailer beams can be installed according to actual needs.

[0048] Example 2

[0049] Based on Example 1, a welding machine 11 and a dust collector 12 are installed on the upper part of the top beam of the welding station gantry 5, and the welding machine 11 provides power to the welding robot 6.

[0050] It also includes an integrated dust hood (not shown in the figure), which is located on the front and rear sides of the welding table 1.

[0051] In this way, the welding fumes can be collected and treated during the welding process through the integrated dust hood and dust collector 12, resulting in pollution-free operation and a clean and tidy overall environment.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
