Then the flipping part drives the towel rack body to flip so that the bottom surface of the towel rack body faces upward. Then the driving part drives the work station frame to reset and welds a row of joints on one side of the other side of the towel rack body through the spot welding group, thereby achieving one-time filling welding of a row of joints on both sides of the towel rack body, avoiding the problem that the joints of the towel rack body are only welded on one side after welding, which leads to the problem of loose welding of the towel rack body. This solves the problem that when welding the towel rack, the welding gun can only fill weld the joints on one side of the towel rack at a time due to the distance between the welding gun and the transport platform.

[0021] 2. A brazing solder device and a towel rack welding method based on visual AI. During the brazing process, the towel rack body is affected by the contact between the welding gun and the towel rack body, which can easily cause the towel rack body to shift in position. Even before brazing, the horizontal and vertical frames of the towel rack body are in a loose state. After the welding work is completed, the size of the towel rack body is easily deviated. By setting the clamping parts, the plywood clamps the two sides of the towel rack body with pressure, so that the horizontal and vertical frames of the towel rack body are in a compressed state, preventing the problem of size deviation after the towel rack body is welded. At the same time, the clamping and positioning of the clamping parts can prevent the towel rack body from shifting in position during the welding process. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The clamping device 6 is arranged on the work station frame 31, and the clamping device 6 includes a clamping part 61, a flipping part 62 and a driving part 63. The clamping part 61 positions and fixes both sides of the towel rack body 4. After the spot welding group 51 completes welding the top surface of the towel rack body 4, the driving part 63 drives the work station frame 31 to move downward and controls the towel rack body 4 away from the transport group 32, and at the same time drives the towel rack body 4 to flip so that the bottom surface of the towel rack body 4 faces upward, and the bottom surface of the towel rack is welded by the spot welding group 51.

[0039] Specifically, the towel rack body 4 is placed on the manual loading station 2, and the towel rack body 4 is transported to the assembly line station 3 through the manual loading station 2. The assembly line station 3 transports the towel rack body 4 to the bottom of the spot welding device 5. When the towel rack body 4 moves to the bottom of the spot welding device 5, the clamping parts 61 in the clamping device 6 fix the two sides of the towel rack body 4. After the towel rack body 4 is fixed, the control group 52 drives the spot welding group 51 to adjust its position on the assembly line station 3, and welds a row of joints on one side of the top surface of the towel rack body 4 through the spot welding group 51. After the row of joints on one side of the top surface of the towel rack body 4 are welded, the driving part 63 runs to drive the station frame 31 and the towel rack body 4 move downward at the same time, driving the towel rack body 4 away from the transport group 32, and at the same time the flipping member 62 runs, driving the towel rack body 4 to flip, so that the bottom surface of the towel rack body 4 flips upward, and then the driving group drives the station frame 31 and the towel rack to reset, and the spot welding group 51 is used to weld a row of joints on one side of the bottom surface of the towel rack body 4. After the welding of the towel rack body 4 is completed, the clamping member 61 releases the towel rack body 4, and then the transport group 32 drives the towel rack body 4 conveyor belt 321 to the next visual point on the assembly line station 3 at the bottom of the copper paste machine 1, and the spot welding group 51 is used to weld a row of joints on the other side of the top and bottom surfaces of the towel rack body 4;

[0040] After the spot welding group 51 completes welding of a row of joints on one side of the top surface of the towel rack body 4, the driving member 63 is set to drive the work station frame 31 and the towel rack body 4 to move downward at the same time and away from the spot welding group 51. At the same time, the driving member 63 drives the flipping member 62 to move upward, so that the towel rack body 4 in the flipping member 62 is away from the transport group 32. Then the flipping member 62 drives the towel rack body 4 to flip so that the bottom surface of the towel rack body 4 faces upward. Then the driving member 63 drives the work station frame 31 to reset and welds a row of joints on one side of the other side of the towel rack body 4 through the spot welding group 51, thereby achieving the goal of filling welding a row of joints on both sides of the towel rack body 4 at one time, avoiding the problem that the joints of the towel rack body 4 are only welded on one side after welding, which leads to the problem of loose welding of the towel rack body 4. This solves the problem that when the towel rack is welded, the welding gun can only fill weld the joints on one side of the towel rack at one time due to the distance between the welding gun and the transport platform.
