[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 2 As shown, the present invention provides an automatic welding system, including a control module 1, to which an input module 2 and an output module 3 are connected, respectively. The input module 2 is provided with a signal detection unit 4, a position detection unit 5, and a motion detection unit 6, all of which are electrically connected to the control module 1, respectively. The output module 3 is provided with a supporting unit 7, a welding unit 8, and an execution unit 9, all of which are electrically connected to the control module 1, respectively. The execution unit 9 pushes the steel plate to be welded onto the supporting unit 7. During the pushing process, when the corresponding signal detection unit 4, position detection unit 5, or motion detection unit 6 is valid, the control module 1 controls the welding unit 8 to weld the steel plate. Specifically, the control module 1 adopts an S7-200 type PLC controller, and its corresponding input and output pin settings and internal program control instruction codes can be set according to the common knowledge or operating habits of those skilled in the art, and are not excessively limited here.

[0021] The signal detection unit 4 comprises a photoelectric sensor 10, which detects the operating status of each output component. The position detection unit 5 comprises a position and motion detection sensor 11, which detects the position of each output component. The motion detection unit 6 comprises a photoelectric encoder 12, which detects the distance traveled by each output component. The output module 3 further comprises a drive unit 24, which comprises a servo motor 25 and a stepper motor 26, respectively, for driving the corresponding output device.

[0022] like Figure 2As shown, the supporting unit 7 includes a left welding platform 13 and a right welding platform 14. Two steel plates to be welded are placed on the left welding platform 13 and the right welding platform 14 respectively, so as to achieve a platform processing effect of the steel plates.

[0023] like Figure 2 As shown, the output module 3 also includes a feeding unit 29, which is configured as a left feeding bin 27 and a right feeding bin 28. The left feeding bin 27 and the right feeding bin 28 are respectively configured corresponding to the left push rod 16 and the right push rod 17. The execution unit 9 includes the left push rod 16 and the right push rod 17. When the device is started, when the photoelectric sensors 10 on the left welding table 13 and the right welding table 14 detect that there are steel plates to be welded, the left push rod 16 and the right push rod 17 are driven to set their positions so as to facilitate the next action. When a new batch of steel plates is to be welded, the left push rod 16 and the right push rod 17 are respectively extended forward to push the steel plates to be welded on the left feeding bin 27 and the right feeding bin 28 forward to the left conveyor belt 20 and the right conveyor belt 21. As shown Figure 2 As shown, the output module 3 also includes a conveying unit 19, which is configured as a left conveyor belt 20 and a right conveyor belt 21. The left conveyor belt 20 is arranged at one end of the left welding table 13, and the right conveyor belt 21 is arranged at one end of the right welding table 14. Photoelectric encoders 12 are respectively provided on the left conveyor belt 20 and the right conveyor belt 21.

[0024] When the steel plates to be welded arrive at the conveyor belt, the rotary encoder drives the left conveyor belt 20 and the right conveyor belt 21 to rotate and limit the running position at the same time, driving the steel plates to be welded toward the left welding table 13 and the right welding table 14. When the steel plates to be welded arrive at the left welding table 13 and the right welding table 14, the photoelectric sensors 10 configured thereon receive electrical feedback, indicating that the steel plates to be welded have reached the welding position, and then the next step of welding work is carried out.

[0025] Welding unit 8 comprises a welding robot 18, specifically an arc welding robot. Positioned beneath left and right welding stations 13 and 14, the welding robot 18 begins welding when the plates arrive at their intended position, joining the two plates together to form a single, complete plate. Once welding is complete, a loading and unloading robot 23, positioned above welding unit 8, retrieves the completed plates, completing the welding of the two plates.

[0026] In summary, the automatic welding system provided by this utility model, through the establishment of an automated welding production line, makes the entire welding process simple and flexible, requires less production line investment, and can complete complex control instructions. Compared with traditional manual arc welding, it is not only more stable and ensures welding quality, but also simplifies equipment maintenance and installation and commissioning, greatly improving welding efficiency.
