The seam-finding assembly 2 includes a fixing plate 21 fixed to the rear side of the left end of the transmission frame 1. A cylinder 23 is mounted on the top rear end of the fixing plate 21. The telescopic end of the cylinder 23 is fixedly connected to the rear end of a seam-finding driven plate 22. The bottom ends of the seam-finding driven plate 22 are connected to the fixing plate 21. The top guide rails at both ends are slidably connected. The top of the mouth-finding driven plate 22 is equipped with a driven wheel 24. The front left side of the transmission frame 1 is provided with a fixed base plate 25. The top of the guide rails at both ends of the fixed base plate 25 is equipped with a mouth-finding transmission plate 26. The top front end of the mouth-finding transmission plate 26 is equipped with a geared motor 27. The top rear end of the mouth-finding transmission plate 26 is equipped with a transmission wheel 28. The output end of the geared motor 27 and the bottom end of the transmission wheel 28 are both equipped with sprockets 29. The sprockets 29 are connected by a chain 210. The side of the mouth-finding transmission plate 26 near the opening barrel 3 is provided with an optical fiber sensor. The front end of the fixed plate 21 and the rear end of the mouth-finding transmission plate 26 are both equipped with racks. The racks are connected by a synchronous shaft drive.

[0023] A second cylinder 211 is provided on the bottom plate at the left end of the transmission frame 1. The telescopic end of the second cylinder 211 is fixedly connected to the bottom of the connecting plate 212. The bearing inside the connecting plate 212 is fixedly connected to the bottom of the rotating rod of the push plate 213.

[0024] The inner seam spraying mechanism 4 includes a servo module 41. A support rod 42 is installed on the rear side of the lifting plate of the servo module 41. A connecting rod 43 is provided at the top of the support rod 42. A fixing rod 44 is installed at the rear end of the connecting rod 43. A paint spray head 45 is installed on the fixing rod 44. The nozzle of the paint spray head 45 faces the inner seam of the open barrel 3.

[0025] The rotating drum assembly mechanism 7 includes a base frame 71 fixed to the bottom right end of the transmission frame 1. Dual-axis cylinders 72 are mounted on the top of the left and right ends of the base frame 71. The telescopic ends of the dual-axis cylinders 72 are fixedly connected to the bottom ends of the lifting connecting block 73. An electromagnet disc 74 is mounted on the top of the lifting connecting block 73. A rotating drum motor 75 is mounted on the bottom of the lifting connecting block 73. The output end of the rotating drum motor 75 is fixedly connected to the rotating rod at the bottom end of the electromagnet disc 74.

[0026] The right front end of the transmission frame 1 is provided with a right fixed base plate 61. The top front end of the right fixed base plate 61 is vertically connected to the bottom of the second support rod 62. The second support rod 62 is equipped with a second paint spray head 63, and the spray nozzle of the second paint spray head 63 faces the outer seam of the open barrel 3.

[0027] Place the open bucket 3 stably on the conveyor chain inside the transmission frame 1, and let the conveyor chain drive the open bucket 3 to move towards the opening-finding assembly mechanism 2. When the open bucket 3 moves to the working position of the opening-finding assembly mechanism 2, the second cylinder 211 is activated, and its telescopic end pushes the connecting plate 212 upward. The push plate 213 then pushes the open bucket 3 upward away from the conveyor chain. The cylinder 23 is activated, and its telescopic end pushes the opening-finding driven plate 22 to slide forward along the guide rails at the top of both ends of the fixed plate 21. The opening-finding driven plate 22 drives the opening-finding transmission plate 26 to move through the rack and synchronous shaft, so that the driven wheel 24 and the transmission wheel 28 approach the open bucket 3.

[0028] The geared motor 27 starts and drives the transmission wheel 28 to rotate through the sprocket 29 and chain 210. The transmission wheel 28 and the driven wheel 24 cooperate to clamp the open barrel 3, causing the open barrel 3 to rotate. The fiber optic sensor mounted on the side detects the weld and stops rotating. The open barrel 3 then slowly reverses and stops rotating when the fiber optic sensor detects the weld again, thus completing the weld positioning.

[0029] The servo module 41 is activated, and its lifting plate lowers the support rod 42, connecting rod 43, and fixing rod 44, allowing the paint spray head 45 to accurately enter the interior of the open barrel 3 and align with the inner seam. The paint spray head 45 then begins spraying paint into the inner seam. Simultaneously, based on the size of the open barrel 3 and the weld length, the servo module 41 controls the paint spray head 45 to move up and down in the vertical direction to ensure that the inner seam is completely covered with paint. After the inner seam is painted, the servo module 41 raises the paint spray head 45 back to its initial position.

[0030] When the open barrel 3 moves to the working position of the rotating barrel assembly mechanism 7, the dual-axis cylinder 72 is activated, and its telescopic end pushes the lifting connecting block 73 to rise, so that the electromagnet plate 74 contacts the bottom of the open barrel 3 and attracts the open barrel 3. The rotating barrel motor 75 is activated, driving the electromagnet plate 74 and the open barrel 3 to rotate. During the rotation of the open barrel 3, the second paint spray head 63 begins to spray paint onto the outer seam of the open barrel 3 to ensure that the outer seam is evenly covered with paint. After the outer seam is sprayed, the dual-axis cylinder 72 drives the lifting connecting block 73 to descend, the electromagnet plate 74 separates from the open barrel 3, and the open barrel 3 continues to move to the next process with the conveyor chain of the transfer frame 1.

The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
