[0028] A multi-station combined welding workstation includes a frame 2 and welding mechanisms 3 arranged on both sides of the frame 2. The two welding mechanisms 3 are symmetrically arranged on both sides of the frame 2. The frame 2 is equipped with a maintenance platform, a ladder, and an inspection passage.

[0029] Each welding mechanism 3 includes a robotic welding torch 31, a mounting base 32, a working frame 36, a transmission component 37, a rotation component 39, and a limiting component 38. The robotic welding torch 31 is mounted on the frame 2 via a three-axis drive device 33. The robotic welding torch 31 can move along the X, Y, and Z axes. The robotic welding torch 31 is used to weld workpieces within the working frame 36. A laser weld seam tracker is installed on the robotic welding torch 31. The working frame 36 is rotatably mounted on the mounting base 32 via the rotation component 39. The transmission component 37 is located within the working frame 36, and the limiting component 38 is located on the working frame 36.

[0030] Furthermore, the frame 2 is also equipped with an automatic torch cleaner 34 and a wire spool 35 for supplying welding wire to the robotic welding torch 31. The automatic torch cleaner 34 is used to clean the welding liquid remaining in the robotic welding torch 31.

[0031] The rotating assembly 39 includes a transmission chain 392, a transmission wheel, a support wheel 391, and a drive source. The support wheel 391 is rotatably connected to the top of the mounting base 32. There are four support wheels 391, located at both ends of the working frame 36. Each support wheel 391 abuts against the two side walls of the working frame 36 and rolls with the working frame 36. The transmission chain 392 is located at the end of the working frame 36. The transmission wheel is rotatably connected to the mounting cavity in the mounting base 32. The transmission wheel and the transmission chain 392 drive each other to rotate the working frame 36 around its axial direction. The drive source is located on the mounting base 32 to drive the transmission wheel to rotate.

[0032] The working frame 36 is cylindrical, with a notch 361 on its side wall, resulting in a C-shaped cross-section. Both ends of the working frame 36 are openings for a feed inlet and a discharge outlet, respectively. A transmission cavity 362 is located inside the working frame 36, communicating with the notch 361, the feed inlet, and the discharge outlet. The material moves from the feed inlet towards the discharge outlet along the Y-axis, and the working frame 36 is axially aligned along the Y-axis. Initially, the openings face the X-axis. Furthermore, multiple supporting ribs 363 are provided circumferentially on the side wall of the working frame 36.

[0033] The transmission assembly 37 is disposed on two opposite side walls inside the transmission cavity 362. The transmission assembly 37 includes a mounting frame 371 and multiple transmission wheels 373. The multiple transmission wheels 373 are arranged along the Y-axis. The mounting frame 371 is connected to the transmission cavity 362 through an adjusting cylinder 372. The adjusting cylinder 372 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. The transmission wheels 373 are rotatably connected to the mounting frame 371. The multiple transmission wheels 373 are driven by a sprocket structure. A set of support rollers 375 is also provided on the side wall opposite to the notch 361 inside the transmission cavity 362. The set of support rollers 375 includes a support plate 374, a support cylinder 376, and support rollers 375. The support cylinder 376 is connected to the side wall opposite to the notch 361 inside the transmission cavity 362, and the output shaft of the support cylinder 376 is oriented towards the notch 361. The support plate 374 is connected to the output shaft of the support cylinder 376. Multiple support rollers 375 are provided and arranged along the Y-axis. The support rollers 375 are rotatably connected to the support plate 374. The adjusting cylinder 372 can drive the two mounting brackets 371 to move closer or further apart to adjust the distance between the two transmission components 37, thereby clamping the plate material entering the transmission cavity 362. When the plate material enters the transmission cavity 362 from the feed port, the two transmission components 37 clamp the plate material and transmit the plate material along the Y-axis. The support rollers 375 abut against the side wall of the plate material and roll to assist in the transmission. The limiting assembly 38 includes two limiting electric cylinders 381, which are arranged opposite to each other on both sides of the notch 361 on the working frame 36. The output ends of the limiting electric cylinders 381 are arranged opposite to each other, and the output ends of the two limiting electric cylinders 381 move closer to each other to clamp the plate, thereby preventing the plate from sliding out of the notch 361.

[0034] Furthermore, the multi-station combined welding workstation also includes a base 1, on which a track 11 is arranged along the Y-axis. The bottom of the mounting base 32 is provided with a traveling wheel 321 adapted to the track 11 and a motor for driving the traveling wheel 321 to rotate, thereby adjusting the position of the work frame 36.

[0035] The implementation principle of this utility model is as follows:

[0036] The sheet material is fed into the transfer chamber 362 through the inlet. Two transfer components 37 clamp the sheet material, and the limit cylinder 381 extends to clamp the sheet material. At the initial position (e.g., ...), ... Figure 4 (As shown in small figure a), at this time, side B of the plate is opposite to the notch 361. The robot welding gun 31 welds one end of the plate along its length. Then, the work frame 36 is rotated 90 degrees from its initial position for positioning (as shown in small figure a). Figure 4 As shown in the small figure (b in the figure), the notch 361 is made to face vertically upwards. As shown in the figure, the robot welding gun 31 moves along the Y-axis direction through the three-axis drive device 33 to weld the half-V opening on the long edge B side of the plate near the notch 361; the track 11 combined with the C-type displacement device rotates the plate to a 180-degree positioning position (as shown in the figure). Figure 4 (As shown in the small diagram), the robotic welding gun 31 welds the plate at the other end along its length. After welding, the plate is transferred to the RGV transport vehicle for standby. The track 11 combined with the C-type positioning device returns to the 0-degree position (as shown in the small diagram). Figure 4 As shown in the small diagram (d in the diagram), the RGV conveyor transfers the sheet metal back into the track 11 combined C-type positioning device. At this point, the side wall that was originally opposite to the support roller 375 is now opposite to the notch 361. The A side of the sheet metal is now opposite to the notch 361. The sheet metal is then repositioned 90 degrees to weld the half of the V-shaped notch on the A side. After welding is completed, the track 11 combined C-type positioning device returns to the 0-degree position and transfers the sheet metal out.
