[0031] Understandably, by setting up slider 100 and power component 110, slider 100 can reciprocate between a first position and a second position. The first position can be a feeding station, and the second position can be a welding station. In the first position, the part to be welded is placed into the positioning groove 130. The power component 110 drives slider 100 to move to the second position, so that slider 100 drives positioning seat 120 to move to the welding station. Thus, automated feeding is achieved, eliminating the need for operators to approach the welding station, reducing the impact of welding fumes on operators, and improving the automation level of the equipment.

[0032] It should be noted that the power assembly 110 can be composed of a motor, a screw, and a nut.

[0033] A welding repair device according to an embodiment of the present invention further includes a detection mechanism, which includes an industrial camera 140 and a vision processor 150 connected to the industrial camera 140.

[0036] Understandably, by setting up an automatic welding torch and a moving mechanism, the moving mechanism drives the automatic welding torch to move according to the position of the dents and pores, so that the automatic welding torch is close to the part to be repaired and repairs the dents and pores. Thus, there is no need for manual repair of dents and pores, improving the repair welding efficiency.

[0037] In some embodiments of this utility model, reference is made to Figure 1 The industrial camera 140 is equipped with a suspension rod, the end of which has a collar 170. The detection mechanism has a vertical rod 180, the collar 170 is sleeved on the vertical rod 180, and the collar 170 is threadedly connected to a locking bolt 190, the end of which abuts against the vertical rod 180.

[0038] Understandably, the industrial camera 140 is connected to the collar 170 via a suspension rod. The collar 170 is fitted onto the upright 180. The collar 170 can move up and down on the upright 180 to adjust the height of the industrial camera 140, so that the industrial camera 140 can accurately photograph the part to be repaired and welded. The collar 170 can be fixed to the upright 180 using a locking bolt 190.

[0039] In some embodiments of this utility model, reference is made to Figure 2A light source 200 is provided above the positioning base 120. The light source 200 is arranged in the second position and is used to illuminate the part to be repaired by welding.

[0040] Therefore, by using the light source 200 to increase the brightness of the welding station, the industrial camera 140 can take a picture of the cleaning process, which is beneficial for the vision processor 150 to accurately analyze the location of the pit.

[0041] In some embodiments of this utility model, the top of the slider 100 has a support plate 210, the top of the support plate 210 is provided with a positioning pin 220, and the positioning seat 120 is provided with a positioning hole that cooperates with the positioning pin 220, thus making it easier to install the positioning seat 120 on the support plate 210.

[0042] In some embodiments of this utility model, reference is made to Figure 1 and Figure 3 The welding repair mechanism has a support, the support has a column 230 and a crossbeam 240 connected to the top of the column 230, and the moving component is installed on the crossbeam 240.

[0043] Specifically, the moving component includes a first linear moving module 250, a second linear moving module 260, and a lifting unit 270. The first linear moving module 250 and the second linear moving module 260 are perpendicularly connected to each other in the horizontal direction, and the lifting unit 270 is connected to the second linear moving module 260.

[0044] Therefore, the first linear motion module 250 and the second linear motion module 260 have high movement accuracy. The first linear motion module 250 and the second linear motion module 260 drive the automatic welding gun to move horizontally, so that the automatic welding gun can accurately repair the parts.

[0045] It should be noted that the lifting unit 270 can be a cylinder, which can be used to drive the automatic welding gun to approach the part to be welded.

[0047] Therefore, when the positioning seat 120 moves from the first position to the second position, the first cylinder 290 drives the baffle 280 to rise, so that the positioning seat 120 can move smoothly to the second position. During the welding process, the first cylinder 290 drives the baffle 280 to fall, and the baffle 280 is used to prevent the bright light generated during the welding process from damaging the operator's eyes.

[0048] Since welding generates fumes, the rising fumes can cause the industrial camera 140 to capture unclear images. In some embodiments of this invention, a fume extraction pipe 300 is provided above the positioning base 120. The fume extraction pipe 300 is connected to a fan 310 and is positioned close to the industrial camera 140. Thus, the fan 310 and the fume extraction pipe 300 work together to extract the fumes, reducing the amount of fumes adhering to the industrial camera 140.

[0049] In some embodiments of this utility model, the smoke inlet of the smoke extraction pipe 300 is provided with a conical smoke guide hood 320. Therefore, the large diameter of the conical smoke guide hood 320 is conducive to the smoke entering the smoke extraction pipe 300 and reduces the impact of the smoke on the industrial camera 140.
