[0025] The beneficial effects of the present invention are as follows:

[0026] 1. The automatic seam-finding welding machine for steel drums described in the present invention utilizes a barrel body loading assembly, a barrel cover loading assembly, a barrel body material moving assembly, and a barrel cover material moving assembly to enable multiple barrel covers and barrel bodies to be precisely spliced ​​in sequence before welding, thereby eliminating the need for workers to manually load the barrel covers and barrel bodies, and reducing the labor intensity of workers. In addition, compared with the method of loading with a robot, this method can transform the originally messily stacked barrel bodies and barrel covers into an orderly arranged state. The electric chuck and suction cup can clamp the barrel body and barrel cover by moving only according to a preset path, reducing the difficulty of clamping. Moreover, the seam between the barrel body and the barrel cover is precisely aligned with the welding gun, thereby autonomously completing the operation of finding the seam, which is conducive to improving the efficiency and stability of the entire welding process.

[0027] 2. The automatic seam-finding and welding machine for steel drums described herein utilizes a pusher assembly. During the ascent of the lifting plate and telescopic plate, when the distance between their upper surfaces and the pusher equals the barrel diameter, cylinder 3 drives the pusher to move, allowing it to pass through the strip-shaped through-hole in the loading box. If a barrel rests on the lifting plate and telescopic plate, the pusher pushes it down, and the lifting plate continues to rise. This ensures that all barrels that slide onto the conveyor belt remain flat, preventing barrels from resting on the conveyor belt and affecting subsequent clamping.

[0028] 3. The automatic seam-finding and welding machine for steel drums described in the present invention can move the drum cover stuck at the pipe opening by driving the top blocks through the through holes on the blanking plate one by one and squeezing the elastic cloth when the drum cover is in the funnel-shaped structure, until the drum cover can smoothly enter the pipe opening, thereby ensuring the subsequent normal positioning of the drum cover.

[0060] The barrel cover material moving assembly includes a screw guide rail four 32 installed on one side of the upper end surface of the base 1, a transverse frame 2 is slidably provided on the screw guide rail four 32, a screw guide rail five 33 is installed on one side of the transverse frame 2, a lifting plate two 34 is slidably provided on the screw guide rail five 33, a flip frame 36 is rotatably provided on one side of the lifting plate two 34, one end of the lifting plate two 34 is fixedly connected to a motor three 35, the output end of the motor three 35 is fixedly connected to one end of the flip frame 36, a vacuum pump 37 is fixedly connected to one side of the flip frame 36, the air inlet of the vacuum pump 37 is connected to an air pipe 38, a suction cup 39 is provided at one end of the air pipe 38, and the air pipe 38 passes through the flip frame 36 and is fixedly connected to it.

[0061] Specifically, in the prior art, when welding the lid and barrel of a steel drum, the lid and barrel must first be fixed in place and fitted together before welding the joint. However, when welding a large number of lids and barrels, operators must frequently fix the lids and barrels in place, which is labor-intensive. When a robot is used to load the lids and barrels instead of operators, if the lids and barrels are piled up in a disorderly manner, the robot will have difficulty accurately grasping them according to the preset path, thus affecting the normal progress of the welding work.

[0062] Therefore, in order to solve the above problem, the working principle of this embodiment is as follows:

[0063] First, it is used for the same batch of barrel lids and barrel bodies with the same specifications. Because multiple blanking plates 40 and elastic cloth 42 cooperate to form a funnel-shaped structure, the radial rods 41 can be driven to slide on the fixed ring 1 4 by rotating the threaded rods 52 driven by motor 6 53. Furthermore, the movement of one radial rod 41 causes all radial rods 41 to move synchronously, driven by connecting rod 1 43 and rotating ring 5. This allows the blanking plates 40 to move, and the size of the elastic cloth 42 to change according to the position of the blanking plates 40. This allows the size of the entire funnel-shaped structure to be adjusted, and the diameter of the lower pipe of this funnel structure can be made equal to the diameter of the barrel lid.

[0064] Then, depending on the barrel diameter, cylinder 4 (17) drives the telescopic plate (16) to move, causing it to slide relative to the lifting plate (15). Since the lifting plate (15) and the telescopic plate (16) cooperate to form a rectangular plane, the area of ​​the rectangular plane can be adjusted by driving the telescopic plate (16) to move. This allows the width of the rectangular plane to be equal to the barrel diameter. Furthermore, as the telescopic plate (16) moves, the placement plate (12) also moves under the action of cylinder 2 (11), ensuring that the placement plate (12) and the telescopic plate (16) remain in contact. Then, cylinder 1 (9) drives the adjustment plate (10) to move. The adjustment plate (10) cooperates with the frame (8) to form a loading channel on the conveyor belt (7), with the width of the loading channel equal to the barrel diameter.

[0065] After the above-mentioned adjustment work is completed, multiple barrel bodies and barrel lids are placed on the placement plate 12 and in the funnel-shaped structure respectively. When the barrel body is on the placement plate 12, the lifting plate 15 is driven to move back and forth up and down by the screw guide rail 18, and the upper surface of the lifting plate 15 in the initial state is aligned with the upper surface of the placement plate 12. And because the lifting plate 15 and the placement plate 12 are arranged at an angle, the barrel body will slide onto the lifting plate 15 and the telescopic plate 16. In addition, because the width of the rectangular plane formed by the lifting plate 15 and the telescopic plate 16 is equal to the diameter of the barrel body, the lifting plate 15 and the telescopic plate 16 will lift the barrel body, and the barrel body will not be placed side by side along the width direction of the rectangular plane, but will only be arranged along the length direction of the rectangular plane. Furthermore, the barrel body is typically longer than its diameter. Therefore, if either end of the barrel body is placed on the lifting plate 15 and the telescopic plate 16, it will fall off the upper surface of the lifting plate 15 and the telescopic plate 16 as they rise due to unstable center of gravity. Therefore, the barrel body that can be lifted by the lifting plate 15 and the telescopic plate 16 is parallel to the length of the lifting plate 15. When the edge of the lifting plate 15 is aligned with the surface of the conveyor belt 7, the barrel body in the rectangular plane will slide onto the conveyor belt 7. Furthermore, due to the position limit of the adjustment plate 10, the barrel body on the conveyor belt 7 will be arranged horizontally.

[0066] When the barrel follows conveyor belt 7 and reaches its end, infrared sensor 63 detects a signal. Conveyor belt 7 then stops. Because electric chuck 30 can adjust its position in the x, y, and z axes through the coordination of screw guide rail 2 19, air cylinder 5 21, and screw guide rail 3 28, the clamping end of electric chuck 30 precisely penetrates the barrel's interior and secures it. Subsequently, motor 2 31 drives the clamped barrel to rotate 180 degrees, aligning the barrel's axis with the axis of ring gear 3.

[0067] When the barrel cover is in a funnel-shaped structure composed of a blanking plate 40 and an elastic cloth 42, since the pipe opening of the funnel-shaped structure can only pass one barrel cover at a time, the barrel covers will be arranged and laid flat in the inner cavity of the pipe, and the barrel covers will be blocked by the baffle 45. Then, according to the thickness of the barrel cover, the height of the clamping block 61 is adjusted through the screw guide rail six 59 so that the clamping block 61 is aligned with the barrel cover that fits the baffle 45. Then, under the drive of the cylinder seven 49, the barrel cover is clamped by the clamping block 61. Subsequently, the baffle 45 can be driven away from the bottom of the blanking plate 40 by the cylinder nine 64. At this time, the suction cup 39 is aligned with the bottom of the barrel cover, and the axis of the suction cup 39 coincides with the axis of the barrel cover. Then, the suction cup 39 is driven to rise and fit with the bottom of the barrel cover through the screw guide rail five 33, and then the vacuum pump 37 is started to adsorb and fix the barrel cover by negative pressure adsorption. Subsequently, the clamp 61 releases the lid, and the suction cup 39 removes the lid from the pipe. As the lid is removed from the pipe, the clamp 61 must first move upward to clamp the lid above it to prevent it from falling out. Motor 3 35 then drives the lid to rotate 90 degrees, aligning the lid axis with the gear ring 3 axis. Driven by screw guide rail 4 32, the lid moves laterally, fitting the lid to the barrel. At this point, cylinder 6 26 drives the welding gun 25 to move, aligning it with the joint between the lid and the barrel. The welding gun 25 is then turned on. Simultaneously, motor 1 23 drives gear 1 24 to rotate, causing the gear ring 3 to rotate. The welding gun 25 then welds along the joint between the lid and the barrel. Repeating this process allows multiple lids to be precisely joined to the barrel body in sequence, and then welding can proceed. This eliminates the need for workers to manually load the lids and barrel body, reducing their labor intensity. Furthermore, compared to robotic loading, this method can transform the originally chaotically stacked barrel bodies and lids into a neatly arranged state. The electric chuck 30 and suction cup 39 simply move along a preset path to grasp the barrel body and lid, reducing the difficulty of grasping. Furthermore, the joint between the barrel body and lid is precisely aligned with the welding torch, autonomously completing the joint search operation, which helps improve the efficiency and stability of the entire welding process.

[0068] In this embodiment, Figure 3 、 Figure 4 、 Figure 6 、 Figure 10 、 Figure 12 As shown, the loading box 6 is also provided with a pushing assembly;

[0069] The pushing assembly includes a cylinder three 14 fixedly connected to one side of the outer wall of the feeding box 6, and the piston end of the cylinder three 14 is fixedly connected to the push rod 13. A strip through hole is provided on one side of the feeding box 6 for the push rod 13 to pass through.

[0070] The lower end of the connecting rod 44 is fixedly connected to a slide ring 51, and the slide groove of the slide ring 51 is slidably connected to an arc block 46. Two connecting rods 2 54 are rotatably provided on one side of the arc block 46, and connecting rod 3 55 is rotatably provided on one end of connecting rod 2 54. A connecting block 56 is rotatably provided on one end of connecting rod 3 55. A cylinder 8 57 is fixedly connected to one side of the lower end surface of the connecting block 56, and a top block 58 is fixedly connected to the piston end of cylinder 8 57. A through hole for the top block 58 to pass through is provided on one side of the blanking plate 40.

[0071] A gear 2 50 is rotatably provided on one side of the arc block 46, and the gear 2 50 is engaged with the tooth block on the outer ring of the slide ring 51. A motor 5 48 is fixedly connected to one side of the upper end surface of the arc block 46, and the output end of the motor 5 48 is fixedly connected to the gear 2 50. A motor 4 47 is fixedly connected to one side of the upper end surface of the arc block 46, and the output end of the motor 47 is fixedly connected to one end of the connecting rod 2 54.

[0072] Specifically, in the above embodiment, while the lid and barrel can be aligned and placed for easy clamping, the barrel may be in an upright position when placed on the lifting plate 15 and the telescopic plate 16. This can cause the barrel to be moved onto the conveyor belt 7 to not be in a flat position, thus affecting subsequent clamping. Furthermore, when multiple lids converge into the funnel-shaped pipe, they can easily become stuck at the pipe opening, similarly affecting the subsequent proper securing of the lids.

[0073] Therefore, to address the aforementioned issues, in this embodiment, during use, when the distance between the upper surfaces of the lifting plate 15 and the telescopic plate 16 and the push rod 13 equals the barrel diameter, the air cylinder 14 drives the push rod 13 to move, passing it through the strip-shaped through-hole in the loading box 6. If a barrel rests on the lifting plate 15 and telescopic plate 16, the push rod 13 will push it down, and the lifting plate 15 will continue to rise. This ensures that all barrels that slide onto the conveyor belt 7 remain flat, preventing barrels from resting on the conveyor belt 7 and affecting subsequent clamping.

[0074] After the orientation of the blanking plate 40 is adjusted, the motor 47 drives the connecting rods 2 and 3, 55, to rotate and adjust the position of the ejector block 58 so that it aligns with the through-holes in the blanking plate 40 through which it passes. When the bucket lid is in the funnel-shaped structure, the motor 58 drives the gear 2 50 to rotate, driving the arc block 46 in a circular motion. Each time the ejector block 58 aligns with a through-hole, the cylinder 8 57 drives the ejector block 58 upward, allowing it to pass through the through-hole. Since the through-holes are located at the pipe opening, if the bucket lid is blocked at the pipe opening, the ejector block 58 will lift it. Furthermore, since the elastic cloth 42 is elastic, the ejector block 58 can also compress the elastic cloth 42, forming a bulge thereon. By driving the ejector block 58 through the through-holes one by one and compressing the elastic cloth 42, the bucket lid stuck at the pipe opening can be moved until it can smoothly enter the pipe opening, thus ensuring the proper positioning of the bucket lid.

[0075] Working Principle: Because multiple blanking plates 40 and elastic cloth 42 cooperate to form a funnel-shaped structure, motor 6 53 drives the threaded rods 52 to rotate, causing radial rods 41 to slide on fixed ring 1 4. Furthermore, when one radial rod 41 moves, all radial rods 41 move synchronously, driven by connecting rod 1 43 and rotating ring 5. This allows the blanking plates 40 to move, and the size of the elastic cloth 42 changes according to the position of the blanking plates 40. This allows the overall size of the funnel-shaped structure to be adjusted, with the diameter of the lower pipe of the funnel being equal to the diameter of the barrel lid. Then, depending on the barrel diameter, cylinder 4 17 drives the telescopic plate 16 to slide relative to the lifting plate 15. Because the lifting plate 15 and the telescopic plate 16 cooperate to form a rectangular surface, the area of ​​the rectangular surface can be adjusted by moving the telescopic plate 16. The width of the rectangular plane is equal to the barrel's diameter. Furthermore, as the telescopic plate 16 moves, the placement plate 12 also moves under the action of cylinder 2 11, ensuring that the placement plate 12 and the telescopic plate 16 remain in contact. Cylinder 1 9 then drives the adjustment plate 10 to move. The adjustment plate 10 and the frame 8 cooperate to form a loading channel on the conveyor belt 7, ensuring that the width of the loading channel is equal to the barrel's diameter. After the above adjustment process is completed, multiple barrels and barrel lids are placed on the placement plate 12 and within the funnel-shaped structure, respectively. When the barrel is on the placement plate 12, the lifting plate 15 is driven to reciprocate up and down by the screw guide rail 18. Initially, the upper surface of the lifting plate 15 is aligned with the upper surface of the placement plate 12. Because the lifting plate 15 and the placement plate 12 are tilted, the barrel slides onto the lifting plate 15 and the telescopic plate 16. Furthermore, because the width of the rectangular plane formed by the lifting plate 15 and the telescopic plate 16 is equal to the diameter of the barrel, the lifting plate 15 and the telescopic plate 16 lift the barrel, and the barrels are not arranged side by side along the width of the rectangular plane, but only along the length of the rectangular plane. Furthermore, the barrel is typically longer than its diameter. Therefore, if either end of the barrel rests on the lifting plate 15 and the telescopic plate 16, it will fall off the upper surface of the lifting plate 15 and the telescopic plate 16 as they rise due to the unstable center of gravity. Therefore, the barrel that can be lifted by the lifting plate 15 and the telescopic plate 16 is parallel to the length of the lifting plate 15. When the edge of the lifting plate 15 is aligned with the surface of the conveyor belt 7, the barrel in the rectangular plane slides onto the conveyor belt 7. Due to the position limit of the adjustment plate 10, the barrel on the conveyor belt 7 is arranged horizontally. When the barrel moves along the conveyor belt 7 to the end of the conveyor belt 7, the infrared sensor 63 detects a signal. Conveyor belt 7 then stops. Because electric chuck 30 can adjust its position in the x, y, and z axes through the coordination of screw guide rail 2 19, cylinder 5 21, and screw guide rail 3 28, the clamping end of electric chuck 30 precisely enters the barrel cavity and secures it. Subsequently, motor 2 31 drives the clamped barrel to rotate 180 degrees, aligning the barrel axis with the axis of ring gear 3.When the barrel cover is in a funnel-shaped structure composed of a blanking plate 40 and an elastic cloth 42, since the pipe opening of the funnel-shaped structure can only pass one barrel cover at a time, the barrel covers will be arranged and laid flat in the inner cavity of the pipe, and the barrel covers will be blocked by the baffle 45. Then, according to the thickness of the barrel cover, the height of the clamping block 61 is adjusted through the screw guide rail six 59 so that the clamping block 61 is aligned with the barrel cover that fits the baffle 45. Then, under the drive of the cylinder seven 49, the barrel cover is clamped by the clamping block 61. Subsequently, the baffle 45 can be driven away from the bottom of the blanking plate 40 by the cylinder nine 64. At this time, the suction cup 39 is aligned with the bottom of the barrel cover, and the axis of the suction cup 39 coincides with the axis of the barrel cover. Then, the suction cup 39 is driven to rise and fit with the bottom of the barrel cover through the screw guide rail five 33, and then the vacuum pump 37 is started to adsorb and fix the barrel cover by negative pressure adsorption. Subsequently, the clamp 61 releases the lid, and the suction cup 39 removes the lid from the pipe. As the lid is removed from the pipe, the clamp 61 must first move upward to clamp the lid above it to prevent it from falling out. Motor 3 35 then drives the lid to rotate 90 degrees, aligning the lid axis with the gear ring 3 axis. Driven by screw guide rail 4 32, the lid moves laterally, fitting the lid to the barrel. At this point, cylinder 6 26 drives the welding gun 25 to move, aligning it with the joint between the lid and the barrel. The welding gun 25 is then turned on. Simultaneously, motor 1 23 drives gear 1 24 to rotate, causing the gear ring 3 to rotate. The welding gun 25 then welds along the joint between the lid and the barrel. Repeating this process allows multiple lids to be precisely joined to the barrel body in sequence, and then welding can proceed. This eliminates the need for workers to manually load the lids and barrel body, reducing their labor intensity. Furthermore, compared to loading with a robot, this method can transform the originally chaotically stacked barrels and lids into a neatly arranged state. The electric chuck 30 and suction cup 39 simply move along a preset path to clamp the barrel and lid, reducing the difficulty of clamping. Furthermore, the joint between the barrel and lid is precisely aligned with the welding gun, autonomously completing the seam search, which helps improve the efficiency and stability of the entire welding process. During the ascent of the lifting plate 15 and telescopic plate 16, when the distance between their upper surfaces and the push rod 13 is equal to the diameter of the barrel, the cylinder 3 14 drives the push rod 13 to move, passing it through the strip-shaped through-hole in the loading box 6. If the barrel rests on the lifting plate 15 and telescopic plate 16, the push rod 13 will push it down, and the lifting plate 15 will continue to rise. This ensures that all barrels that slide onto the conveyor belt 7 are in a flat position, preventing the barrel from resting on the conveyor belt 7 and affecting subsequent normal clamping. After the orientation adjustment of the blanking plate 40 is completed, the motor 47 drives the connecting rod 2 54 and the connecting rod 3 55 to rotate, and adjusts the position of the top block 58 so that the top block 58 is aligned with the through hole on the blanking plate 40 for the top block 58 to pass through.When the bucket cover is in the funnel-shaped structure, the motor 5 48 drives the gear 2 50 to rotate, driving the arc block 46 to perform circular motion. Whenever the top block 58 is aligned with a through hole, the cylinder 8 57 drives the top block 58 to rise and pass through the through hole. Since the through hole is set at the pipeline opening, if the bucket cover is blocked at the pipeline opening, the top block 58 will push it up. Moreover, since the elastic cloth 42 is elastic, the top block 58 can also squeeze the elastic cloth 42 to form a bulge on the elastic cloth 42. By driving the top blocks 58 to pass through the through holes one by one and squeezing the elastic cloth 42, the bucket cover stuck at the pipeline opening can be moved until the bucket cover can smoothly enter the pipeline opening, thereby ensuring the normal positioning of the bucket cover in the future.
