[0002] The steel gas cylinder is composed of a circular body in the middle and a hemispherical head at the end. In order to enhance the airtightness of the annular weld of the steel gas cylinder, the inner annular seam of the steel gas cylinder is generally welded.

[0029] The first electrically-controlled flip frame 41 and the second electrically-controlled flip frame 51 are both composed of a power part that provides rotational power and a rotating part that receives power to rotate; the power parts of both are installed on the mounting plate 3, the rotating part of the first electrically-controlled flip frame 41 is connected to the electrically-controlled slider 42, and the rotating part of the second electrically-controlled flip frame 51 is connected to the fixing part 52.

[0030] like Figure 5 and Figure 6As shown, the arc-shaped spring-clip air guide cover 53 is made of elastic steel material; the fixing part 52 is made of an electromagnet; a rubber gasket 54 is fixedly connected to the upper surface of the arc-shaped spring-clip air guide cover 53, and a recessed structure adapted to the middle of the arc-shaped spring-clip air guide cover 53 is provided in the middle of the gasket 54; a plurality of ventilation grooves 5401 are provided on the edge of the gasket 54; the protective soft cover 61 is made of insulating material, which can shield the electromagnetic force generated by the electromagnet on the infrared visual flaw detector 6, thereby preventing the infrared visual flaw detector 6 from being damaged by the electromagnetic force of the electromagnet for a long time.

[0031] The welding and flaw detection steps of an intelligent welding device based on machine vision detection of the present invention are as follows.

[0032] The operator first connects the gas delivery pipe 71 to an air flow delivery device, and connects the air extraction pipe 81 to a vacuum suction device, and then clamps the body and the end cap of the steel cylinder 11 between the two electric control clamps 23 . Then, the electrically-controlled sliding frame 21 drives the steel cylinder body 11 between the two electrically-controlled clamping plates 23 to move to the left along the transverse guide rail 2, allowing the first electrically-controlled flip frame 41 and the second electrically-controlled flip frame 51 on the mounting plate 3 to enter the interior of the steel cylinder body 11, and then the first electrically-controlled flip frame 41 drives the welding gun 43 on the electrically-controlled slide block 42 to flip counterclockwise by 90 degrees at a front-view angle, so that the welding parts of the welding gun 43 are vertically aligned downward with the lower area of ​​the inner ring seam of the steel cylinder body 11. At the same time, the second electrically-controlled flip frame 51 drives the arc-shaped spring deflector 53 and the infrared visual flaw detector 6 to rotate counterclockwise by 90 degrees at a top-view angle, so that the arc-shaped spring deflector 53 is close to the front upper area of ​​the inner ring seam of the steel cylinder body 11, and the protective soft cover 61 is close to the front area of ​​the steel cylinder body 11. At this time, the infrared visual flaw detector 6 is in a detection working state facing the front area of ​​the inner ring seam of the steel cylinder body 11 inside the protective soft cover 61. The flipping state of the first electrically-controlled flip frame 41 and the second electrically-controlled flip frame 51 is as shown in FIG. Figure 8 As shown, the fixing part 52 restarts the electromagnet to generate electromagnetic attraction to the arc-shaped spring sheet air deflector 53, so that the arc-shaped spring sheet air deflector 53 made of steel is magnetized and generates weak magnetic attraction to the steel cylinder body 11 through the spacer 54. The arc-shaped spring sheet air deflector 53 uses the weak magnetic attraction to stick to the front upper area of ​​the inner annular seam of the steel cylinder body 11, and a flow channel is left between the middle recessed structure of the spacer 54 and the inner annular seam of the steel cylinder body 11. At the same time, the arc-shaped spring sheet air deflector 53 uses the weak magnetic attraction to push the protective soft cover 61 to stick to the front area of ​​the inner annular seam of the steel cylinder body 11. Since the magnetic attraction between the arc-shaped spring sheet air deflector 53 and the inner wall of the steel cylinder body 11 is isolated and weakened by the spacer 54, the steel cylinder body 11 will not be affected by the extrusion and friction from the arc-shaped spring sheet air deflector 53 and its rotational motion state will not be affected.

[0033] Subsequently, the electrically-controlled rotating frame 22 drives the electrically-controlled clamping plate 23 to rotate slowly clockwise at a left viewing angle, so that the electrically-controlled clamping plate 23 drives the cylinder body 11 to rotate slowly. During this process, each area of ​​the inner annular seam of the cylinder body 11 passes under the welding gun 43 in turn, and the electrically-controlled slider 42 drives the welding gun 43 to move downward close to the inner annular seam of the cylinder body 11. The welding gun 43 welds each area of ​​the inner annular seam of the cylinder body 11 in turn. At the same time, the external vacuum suction equipment performs suction work on the suction head 8 through the suction pipe 81, so that most of the slag and smoke generated by the welding gun 43 during the welding process are sucked away by the suction head 8 above in time. Since the magnetic attraction between the arc-shaped spring deflector 53 and the inner wall of the cylinder body 11 is isolated and weakened by the spacer 54, the magnetization effect of the cylinder body 11 itself will also be greatly weakened. Therefore, the iron filings and welding slag splashed during the welding process are not easily magnetically attracted to the cylinder body 11.

[0034] At the same time, as the electrically controlled rotating frame 22 drives the steel cylinder body 11 to rotate continuously, the inner annular seam welding area of ​​the steel cylinder body 11 will rotate and move along the spacer 54 toward the infrared visual flaw detector 6 after leaving the welding gun 43, and at the same time, the external air flow conveying equipment continuously conveys air flow to the nozzle 7 through the air pipe 71, and the air flow is blown out from the nozzle 7 and flows along the flow channel between the spacer 54 and the inner annular seam of the steel cylinder body 11, so that the inner annular seam welding area of ​​the steel cylinder body 11 is cooled by the air flow, so that the inner annular seam welding area of ​​the steel cylinder body 11 is quickly cooled and formed, and part of the air flow will flow out from each ventilation groove 5401, so that part of the heat absorbed by the air flow during the cooling process is released outward through each ventilation groove 5401 in advance, and the outflowing air flow will carry The heat is sucked away through the suction head 8, which is beneficial to reduce the amount of heat accumulated in the circulation channel between the gasket 54 and the inner annular seam of the steel cylinder body 11, accelerate the cooling efficiency of the welding area of ​​the inner annular seam of the steel cylinder body 11, and make the defective structure in the inner annular seam of the steel cylinder body 11 appear in time. At the same time, when the airflow quickly flows through the welding area of ​​the inner annular seam of the steel cylinder body 11, the welding slag remaining in the inner annular seam of the steel cylinder body 11 can be blown away, which greatly reduces the phenomenon that the defective structure in the inner annular seam of the steel cylinder body 11 is blocked by welding slag. The welding area of ​​the inner annular seam of the steel cylinder body 11 will enter the protective soft cover 61 after leaving the arc-shaped spring-shaped deflector 53, and the defective structure in the inner annular seam of the steel cylinder body 11 will be identified and recorded by the infrared visual flaw detector 6, so that welding work and flaw detection work can be carried out simultaneously.

[0035] The repair welding working steps of the intelligent welding device based on machine vision detection of the present invention are as follows.

[0036] When the infrared visual flaw detector 6 records the existence of a defective structure in the inner annular seam of the steel cylinder body 11, after the welding gun 43 completes the welding work of a circle of the inner annular seam of the steel cylinder body 11, the electrically controlled rotating frame 22 drives the steel cylinder body 11 to rotate, so that the defective structure in the inner annular seam of the steel cylinder body 11 is rotated to align with the welding gun 43, and then the welding gun 43 promptly performs repair welding on the defective structure in the inner annular seam of the steel cylinder body 11, thereby improving the overall welding work efficiency of the steel cylinder body 11.

[0037] Example 2

[0038] like Figure 1-Figure 7 As shown, the difference between this embodiment and embodiment 1 is that a brush 55 made of hard plastic material is provided on the spacer 54 of this embodiment; a plurality of first through holes 5301 structures are provided on the arc-shaped spring deflector 53; and a plurality of second through holes 5402 structures corresponding to the first through holes 5301 structures are provided on the spacer 54.

[0039] During the welding of the inner annular seam of the steel cylinder body 11, the electrically controlled rotating frame 22 drives the steel cylinder body 11 to rotate. During the movement of the welded portion of the inner annular seam of the steel cylinder body 11 along the spacer 54, the welded portion of the steel cylinder body 11 is continuously cooled by the airflow in the spacer 54 and gradually cooled. In addition, during the welding portion of the steel cylinder body 11 passing through the brush 55 on the spacer 54 in sequence, the brush 55 is close to the welded portion of the steel cylinder body 11 to gradually crush and brush off the welding slag agglomerated on the surface thereof. Since the welding slag agglomerated on the surface of the welded portion of the steel cylinder body 11 is a thin layer of brittle structure, the brush 55 of hard plastic material can easily crush the agglomerated welding slag. At the same time, the airflow flowing along the spacer 54 timely crushes the welding slag brushed off by the brush 55, and blows it outward through each of the first through hole 5301 structure and the second through hole 5402 structure, thereby further improving the welding slag treatment effect on the welded portion of the steel cylinder body 11.

[0040] Example 3

[0041] like Figure 1-Figure 7 As shown, the difference between this embodiment and embodiment 1 is that a marking liquid storage tank 9 is installed on the second electrically-controlled flip frame 51 of this embodiment; the liquid outlet of the marking liquid storage tank 9 is connected to an electrically-controlled nozzle 91; the liquid outlet of the electrically-controlled nozzle 91 is located inside the protective soft cover 61, and the direction of the liquid outlet of the electrically-controlled nozzle 91 is the same as the search direction of the infrared visual flaw detector 6; a visual probe 10 is installed in the first electrically-controlled flip frame 41, and a lighting lamp is installed on the visual probe 10, and the search direction of the visual probe 10 is the same as the direction of the welding part of the welding gun 43; a baffle 44 is fixed to the electrically-controlled slider 42.

[0042] During the welding of the inner annular seam of the steel cylinder body 11, when the electrically controlled slider 42 drives the welding gun 43 downward to weld the inner annular seam of the steel cylinder body 11, the electrically controlled slider 42 drives the baffle 44 to move downward and shield the visual probe 10, so as to prevent the strong light generated by the welding gun 43 during the welding work from damaging the image sensor of the visual probe 10. At the same time, it can also prevent the debris generated by the welding gun 43 during the welding work from splashing onto the visual probe 10, thereby providing isolation protection for the visual probe 10. When the infrared visual flaw detector 6 detects a defective structure in the inner annular seam of the steel cylinder body 11, the electrically controlled nozzle 91 controls the marking liquid in the marking liquid storage tank 9 to spray onto the defective structure of the inner annular seam of the steel cylinder body 11. Since the infrared visual flaw detector 6 is at a large distance from the inner annular seam of the steel cylinder body 11, the marking liquid sprayed onto the inner annular seam of the steel cylinder body 11 will not splash onto the infrared visual flaw detector 6.

[0043] Afterwards, during the repair welding of the inner annular seam of the steel cylinder body 11, the electrically controlled slider 42 drives the welding gun 43 to reset upward, and at the same time, the electrically controlled slider 42 drives the baffle 44 upward to leave the visual probe 10, and then, during the self-rotation of the steel cylinder body 11 driven by the electrically controlled rotating frame 22, the visual probe 10 cooperates with the lighting installed thereon to identify the marking liquid on the inner annular seam of the steel cylinder body 11, and then the welding gun 43 repairs the defective structure marked by the marking liquid on the inner annular seam of the steel cylinder body 11, thereby realizing the position of the marking liquid on the inner annular seam of the steel cylinder body 11 through visual identification, thereby improving the accuracy of the welding gun 43 in repairing the defective structure on the inner annular seam of the steel cylinder body 11.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
