DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0021] AsFigures 1 to 3 As shown, an embodiment of the present utility model provides a welding device for a QR code on a liquefied gas tank shield, which is used to weld a metal nameplate printed with a QR code label to the shield of the liquefied gas tank.

[0022] Please refer to Figure 1 and Figure 2 , the welding device for the QR code on the liquefied gas tank shield includes a frame 100. A positioning cylinder 200 is provided on the frame 100. The axial direction of the positioning cylinder 200 is consistent with the Y-axis direction, and a positioning groove 201 is provided on the outer peripheral wall of the positioning cylinder 200. The shield can be positioned by sleeving the shield on the positioning cylinder 200 and placing it in the positioning groove 201. A two-axis moving assembly 300 and a three-axis moving assembly 400 are also provided on the frame 100. A pressing member 500 is provided on the two-axis moving assembly 300, and the pressing member 500 is located above the positioning cylinder 200. The two-axis moving assembly 300 is used to drive the pressing member 500 to move along the X-axis direction and the Z-axis direction respectively and approach or move away from the positioning groove 201. After the shield is placed in the positioning groove 201 and the metal nameplate to be welded is placed on the shield, the two-axis moving assembly 300 drives the pressing member 500 to abut against the metal nameplate and press the metal nameplate, so that the position of the metal nameplate on the shield can be fixed. A welding torch 600 is provided on the three-axis moving assembly 400, and the welding torch 600 is located above the positioning cylinder 200. The three-axis moving assembly 400 drives the welding torch 600 to move along the X-axis direction, the Y-axis direction and the Z-axis direction and approach or move away from the positioning groove 201. The three-axis moving assembly 400 is used to move the welding torch 600 and weld the edge of the metal nameplate to the shield through the welding torch 600, so that the metal nameplate printed with the QR code label and the shield can be welded into one body. A main controller 700 is also provided on the frame 100. The two-axis moving assembly 300, the three-axis moving assembly 400 and the welding torch 600 are respectively electrically connected to the main controller 700. The main controller 700 is used to control the actions of the two-axis moving assembly 300, the three-axis moving assembly 400 and the welding torch 600, so that the welding device for the QR code on the liquefied gas tank shield can automatically perform the welding operation of the metal nameplate.

[0023] Specifically, the operation steps of welding the shield with the QR code label to the shield using the liquefied gas tank shield QR code welding device provided in this embodiment are as follows: First, put the shield on the positioning cylinder 200 and place it in the positioning groove 201 to position the shield. Then, place the metal nameplate with the QR code label at the designated position on the shield. Operate the main controller 700, and the main controller 700 controls the two-axis moving assembly 300 to drive the pressing member 500 to move and approach the positioning groove 201. By the abutment of the pressing member 500 and the metal nameplate, the metal nameplate can be pressed tightly on the shield and the position of the metal nameplate can be fixed. Then, operate the main controller 700 to make the main controller 700 control the three-axis moving assembly 400 to drive the welding torch 600 to move towards the shield and weld the edge of the metal nameplate and the shield into one body through the welding torch 600, so that the metal nameplate with the QR code label can be welded on the shield. After welding is completed, the two-axis moving assembly 300 drives the pressing member 500 away from the positioning groove 201, and the three-axis moving assembly 400 drives the welding torch 600 away from the positioning groove 201. At this time, the shield that has completed the welding operation can be removed from the positioning cylinder 200, and other shields can be placed on the positioning cylinder 200 and the above actions can be repeated to continuously carry out the welding operation. When using the liquefied gas tank shield QR code welding device provided in this embodiment, only the shield and the metal nameplate need to be placed at the designated positions, without manually fixing the metal nameplate and operating the welding torch 600 for welding, effectively improving the production efficiency of liquefied gas tank products and reducing the labor intensity of workers, and the operation is simple and easy to use.

[0024] As Figure 2 and Figure 3 shown, a limiting block 202 is further provided on the outer peripheral wall of the positioning cylinder 200, and the limiting block 202 covers part of the opening of the positioning groove 201. When the shield is placed in the positioning groove 201, it is inserted into the gap between the limiting block 202 and the positioning cylinder 200. The limiting block 202 is used to limit the shield to prevent the shield from falling off the positioning cylinder 200 during the welding process and ensure the stability of the position of the shield on the positioning cylinder 200.

[0025] Specifically, a baffle 203 is further provided on the outer peripheral wall of the positioning cylinder 200. The baffle 203 is located on the side of the positioning cylinder 200 away from the pressing member 500 and is arranged close to the edge of the positioning groove 201. The baffle 203 provided on the positioning cylinder 200 is used to guide the shield into the positioning groove 201, and after the shield is sleeved on the positioning cylinder 200, the baffle 203 contacts the edge of the shield and limits the movement of the shield on the positioning cylinder 200 to prevent the shield from rotating around the positioning cylinder 200 and causing the metal nameplate to be misaligned.

[0026] AsFigure 1 and Figure 3 As shown, the two-axis moving assembly 300 includes a first guide rail 301 arranged along the X-axis direction, a first slider 302 movably arranged on the first guide rail 301, and a first cylinder 303 drivingly connected to the first slider 302. A second guide rail 304 is arranged along the Z-axis direction on the first slider 302, and a movable second slider 305 is arranged on the second guide rail 304. A second cylinder 306 drivingly connected to the second slider 305 is further arranged on the first slider 302. The pressing member 500 is arranged on the second slider 305. The two-axis moving assembly 300 drives the first slider 302 to move on the first guide rail 301 through the first cylinder 303 to drive the pressing member 500 to move along the X-axis direction, and the second cylinder 306 drives the second slider 305 to move on the second guide rail 304 to drive the pressing member 500 to move along the Z-axis direction, so as to respectively adjust the positions of the pressing member 500 in the X-axis direction and the Z-axis direction, ensuring that the pressing member 500 is moved to a position where it abuts against the metal nameplate and presses the metal nameplate against the shield.

[0027] Please refer to Figure 2 and Figure 3 , the pressing member 500 includes a pressing rod 501. A first mounting hole cooperating with the pressing rod 501 is arranged on the second slider 305, and the axial direction of the first mounting hole is the Z-axis direction. A pressing head 502 is arranged at one end of the pressing rod 501 close to the positioning cylinder 200. The pressing member 500 includes the pressing rod 501 and the pressing head 502 arranged at the end of the pressing rod 501. The pressing rod 501 is installed in the first mounting hole on the second slider 305. The pressing head 502 is made of a material with certain elasticity such as rubber or silica gel. When the two-axis moving assembly 300 moves the pressing member 500 to make the pressing member 500 abut against the metal nameplate, the pressing head 502 is in direct contact with the metal nameplate, and the pressing head 502 deforms when abutting against the metal nameplate to ensure that the pressing head 502 fits against the metal nameplate and ensures that the position of the metal nameplate on the shield remains stable.

[0028] In this embodiment, the pressing rod 501 is movably arranged in the first mounting hole. The pressing member 500 further includes a spring 503 sleeved on the pressing rod 501. The opposite ends of the spring 503 in the telescopic direction are respectively abutted against the second slider 305 and the pressing rod 501, and drive the pressing head 502 to move towards the positioning cylinder 200. The elastic force provided by the spring 503 keeps the pressing head 502 in contact with the metal nameplate during welding. At the same time, after the pressing member 500 moves to the position in contact with the metal nameplate and the second slider 305 descends along the Z-axis direction, the pressing rod 501 moves upward along the Z-axis direction in the first mounting hole to prevent the pressing member 500 from being damaged when the second slider 305 continues to descend after the pressing member 500 abuts against the metal nameplate.

[0029] Please refer to Figure 2 and Figure 3 , the three-axis moving assembly 400 includes a third guide rail 401 arranged along the X-axis direction, a third slider 402 movably arranged on the third guide rail 401, and a third cylinder 403 drivingly connected to the third slider 402.

A fourth cylinder 406 drivingly connected to the fourth slider 405 is further arranged on the third slider 402. A fifth guide rail 407 is arranged along the Z-axis direction on the fourth slider 405, and a movable fifth slider 408 is arranged on the fifth guide rail 407. A fifth cylinder 409 drivingly connected to the fifth slider 408 is further arranged on the fourth slider 405. The welding torch 600 is arranged on the fifth slider 408. The third driving assembly drives the third slider 402 to move along the third guide rail 401 through the third cylinder 403 to drive the welding torch 600 to move along the X-axis direction, and drives the fourth slider 405 to move along the fourth guide rail 404 through the fourth cylinder 406 to drive the welding torch 600 to move along the Y-axis direction. It also drives the fifth slider 408 to move on the fifth guide rail 407 through the fifth cylinder 409 to drive the welding torch 600 to move along the Z-axis direction, so as to flexibly control the position of the welding torch 600 in space, ensure that the welding torch 600 can move to the target position for welding operations, and is beneficial to improving the reliability of the liquefied gas tank shroud two-dimensional code welding device.

[0030] Specifically, an installation plate 410 is provided on the fifth slider 408. The installation plate 410 extends towards the positioning cylinder 200, and a second installation hole for cooperating with the welding torch 600 is provided on the installation plate 410. The welding torch 600 is installed on the fifth slider 408 by cooperating with the second installation hole on the installation plate 410, ensuring reliable cooperation between the welding torch 600 and the three-axis moving assembly 400 while preventing the welding torch 600 from shaking during movement, ensuring stable contact at the contact position between the welding torch 600 and the metal nameplate and passport for welding operations, and thus guaranteeing the welding quality.

[0031] As Figure 1 and Figure 3 shown, a camera 800 is further provided on the frame 100. The camera 800 faces the positioning groove 201 and is electrically connected to the main controller 700. The camera 800 is used to capture an image of the metal nameplate placed on the shield and transmit it to the main controller 700. The main controller 700 can identify the position of the metal nameplate based on the image captured by the camera 800, thereby controlling the two-axis moving assembly 300 to move the pressing member 500 to a position where it abuts against the metal nameplate, and controlling the three-axis moving assembly 400 to move the welding torch 600 to the edge of the metal nameplate for welding, which is beneficial to improving the reliability of the liquefied gas cylinder shield QR code welding device.

[0032] Specifically, an installation bracket 101 is further provided on the frame 100. A third installation hole for cooperating with the camera 800 is provided on the installation bracket 101.
