[0002] When using a cylinder, a QR code needs to be installed on one end. According to the newly released national technical standards for the production of liquefied petroleum gas cylinders, each cylinder leaving the factory must have a non-replaceable electronic tag or QR code electronically readable mark securely welded to the protective cover. This facilitates access to cylinder and gas filling information, effectively resolving issues such as unclear cylinder information and the difficulty for cylinder users to accurately determine cylinder safety status and gas filling weight. The old standard for QR codes on cylinders was mostly fixed with rivets. This method was prone to rivet removal after long-term use, causing the QR code to fall off and affecting access to cylinder information.

After pressing, the positioning QR code cylinder 908 is retracted, so that the QR code 904 can be fixed on the cylinder body 4, and then start the laser welding gun 14 to weld the QR code 904 to the cylinder body 4.

[0026] In one embodiment, Figure 5 As shown, one end of the movable frame 907 is fixedly connected to the positive positioning shield cylinder 11, one end of the positive positioning shield cylinder 11 is fixedly connected to the positioning plate 12, and one end of the fixed frame 2 is fixedly connected to the side positioning shield cylinder 13. When the cylinder body 4 is in place, the positive positioning shield cylinder 11 drives the positioning plate 12 and the side positioning shield cylinder 13 to extend at the same time, thereby positioning the shield at one end of the cylinder body 4.

[0027] In one embodiment, Figure 1 As shown, a conveyor belt 3 is provided on the top of the welding machine 1 , and a cylinder body 4 is provided on the surface of the conveyor belt 3 for conveying the cylinder body 4 .

[0028] In one embodiment, Figure 1 As shown, a main platform cylinder 5 is fixedly connected to the top of one end of the welding machine 1, and a rotator 6 is fixedly connected to the top of one end of the main platform cylinder 5. The cylinder body 4 is lifted up by the main platform cylinder 5, and then the rotator 6 is started to drive the cylinder body 4 to rotate, so that the cylinder body 4 can be rotated to a suitable position.

[0029] In one embodiment, Figure 1As shown, the middle top of the welding machine 1 is fixedly connected to a sub-platform cylinder 7, and the assembly line skeleton above the sub-platform cylinder 7 is provided with a support frame 16, which is used to support the cylinder body 4 so that the QR code 904 can be welded on the cylinder body 4.

[0030] In one embodiment, Figure 1 As shown, an intercepting cylinder 10 is fixedly connected to the top of one end of the welding machine 1, which is used to intercept the cylinder body 4 on the conveyor belt 3 to prevent affecting the rotation positioning of other cylinder bodies 4.

[0031] In one embodiment, Figure 3 As shown, a laser welding gun 14 is fixedly connected to the top of the fixing frame 2 for welding the QR code 904 to the cylinder body 4. An upper intercepting cylinder 15 is provided on the top of the fixing frame 2 for intercepting the cylinder body 4 from the top to prevent affecting the processing of other cylinder bodies 4.

[0032] Working principle: The above embodiment discloses an automatic laser welding QR code machine for pressure vessels. When in use, the QR code suction cylinder 910 is started to suck up the QR code 904, and the cylinder body 4 is waited for the signal of the cylinder body 4 being in place. The conveyor belt 3 is started to convey the cylinder body 4, and the cylinder body 4 is lifted up by the main platform cylinder 5. Then, the cylinder body 4 is driven to rotate by starting the rotator 6. The rotator 6 is provided with a sensor so that the cylinder body 4 can be rotated to the appropriate position. The main platform and the auxiliary platform are moved simultaneously by the main platform cylinder 5 and the auxiliary platform cylinder 7 to place the cylinder. The main body 4 moves to the top of the support frame 16, and then the main platform and the auxiliary platform are lowered at the same time through the main platform cylinder 5 and the auxiliary platform cylinder 7. The cylinder body 4 falls on the support frame 16, which can support the cylinder body 4. At the same time, the main platform and the auxiliary platform are reset at the same time. When they are reset to the original position, the push cylinder 906 is started to push the movable frame 907 out. After the movable frame 907 is pushed into place, the QR code suction cylinder 910 is moved to the top of one end of the cylinder body 4, and the positive positioning shield cylinder 11 drives the positioning plate 12 and the side positioning shield cylinder 11 to move upward. The cylinder 13 extends at the same time, and then positions the shield at one end of the cylinder body 4, starts the positioning QR code cylinder 908 to position the QR code 904, and then presses the QR code 904 down to the cylinder body 4 through the suction QR code cylinder 910. After pressing, the positioning QR code cylinder 908 is retracted, so that the QR code 904 can be fixed on the cylinder body 4, and then the laser welding gun 14 is started to weld the QR code 904 to the cylinder body 4. When the welding is completed, the positive positioning shield cylinder 11, the side positioning shield cylinder 13 and the suction QR code cylinder 91 0 reset and retract at the same time, the auxiliary platform cylinder 7 extends to lift the steel cylinder with the QR code welded on it. When the main platform positions the next steel cylinder, the main platform and the auxiliary platform move at the same time. The main platform moves the new steel cylinder to be welded with the QR code to the top of the welding support frame 16. The auxiliary platform moves the steel cylinder with the QR code welded to the empty mine of the flow. Then the main platform cylinder 5 and the auxiliary platform cylinder 7 descend at the same time. The steel cylinder above the main platform welds the QR code. The steel cylinder above the auxiliary platform is placed on the assembly line and flows into the next process along the assembly line. This repetitive cycle makes it possible to weld an average of 4 QR codes per minute, thereby meeting the production rhythm requirements and making the QR code 904 permanently welded and fixed on the bottle body shield. It will not fall off during use, avoiding affecting the viewing of the information on the cylinder body 4.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application.
