Description

Technical Field

[0001] The present application relates to the field of welding wire detection, and in particular to a welding wire feeding detection device. Background Art

[0002] Chinese patent CN114894143A proposes a welding wire diameter detection device for marine engineering. The device detects welding wires of different diameters by replacing different guide grooves and allowing the welding wire to move in the guide grooves. However, only the guide grooves are replaced, and the detection tool is not adjusted accordingly. When the diameter of the welding wire being detected increases, the welding wire will rub against the detection tool, causing damage to the welding wire. In addition, the welding wire currently needs to be stretched tight and straightened during detection, and then reeled after the detection. This pulling and reeling process can easily cause strain on the welding wire, affecting subsequent use. In addition, some types of welding wire are prone to rust. Such rust can cause the diameter of such welding wire to exceed the standard, which can also affect subsequent use. Summary of the Invention

[0042] Specifically, the welding wire delivery includes the following contents:

[0043] The welding wire reel to be inspected is put on the three fourth mounting plates 2010 on the right, and then the staff rotates the right rotary cover 2012 to move backward. The rotary cover 2012 drives the three fourth mounting plates 2010 to move outward through the three connecting rods 2013 to stretch the second spring telescopic rod 209, so that the three fourth mounting plates 2010 are in contact with the inner side of the welding wire reel to support and fix the welding wire reel. Similarly, the three fourth mounting plates 2010 on the left are used to fix the empty welding wire reel; then the end of the welding wire is pulled out to pass around the two first wire guide wheels 2019 and the uppermost second wire guide wheel 308, and finally fixed on the empty welding wire reel. At this time, the welding wire is The wire track is arc-shaped and will not be forced to straighten and cause strain; then the two first motors 207 are controlled to drive the corresponding first transmission shafts 208 to rotate, and the two first transmission shafts 208 drive the corresponding second spring telescopic rods 209 and the fourth mounting plate 2010 to rotate, so that the left welding wire reel rotates to reel in the welding wire, and the right welding wire reel rotates to release the welding wire. In this process, the two electric slide rails 204 are controlled to drive the corresponding electric slider 205 to move back and forth, and the electric slider 205 drives the corresponding first mounting frame 206, the first motor 207, the first transmission shaft 208, the second spring telescopic rod 209 and the fourth mounting plate 2010 to move , so that the welding wire reel moves back and forth, so that the welding wire maintains the same plane during the conveying process and the welding wire can be neatly wound on the welding wire reel. During the welding wire conveying process, the welding wire passes between the second wire guide wheel 308 and the touch plate 3014, and the lower side of the touch plate 3014 is close to the welding wire. If the diameter of the welding wire is too large, the welding wire will contact the touch plate 3014, forcing the touch plate 3014 to move upward, and the touch plate 3014 drives the sliding rod 3013 and the contact plate 3015 to move upward. The contact plate 3015 moves upward to squeeze the distance sensor 3018, and the distance sensor 3018 is detected after being pressed, thereby realizing the detection of the welding wire diameter; after replacing welding wire of other specifications, The second motor 3011 can be used to control the rotation of the second transmission shaft 303, the first mounting plate 304, the fixed shaft 307, and the second wire guide wheel 308, so that the second wire guide wheel 308, whose central groove matches the welding wire, is rotated to be directly below the contact plate 3014. At the same time, the rotation of the first mounting plate 304 drives the four limiting rods 305 to rotate. The corresponding limiting rods 305 abut under the eighth mounting plate 3010, so that the eighth mounting plate 3010 moves up and down, compressing or stretching the third spring telescopic rod 309 to adjust the height, thereby adjusting the height of the touch plate 3014, so that the touch plate 3014 remains close to the welding wire after the detected welding wire diameter changes;During reeling, the left wire reel becomes thicker as more wire is added, while the right wire reel becomes thinner, which reduces the thickness. This can cause changes in both ends of the wire feeding track, which can lead to excessive stretching and strain of the wire. Therefore, during the reeling process, the first cylinder 2015 is controlled to drive the fifth mounting plate 2016 and the two first wedge blocks 2017 to move forward. The two first wedge blocks 2017 force the two second wedge blocks 2020 to move, with the left second wedge block 2020 moving downward and the right second wedge block 2020 moving upward. The two second wedge blocks 2020 drive the corresponding third mounting plate 203 to move, causing the left wire reel to move downward and the right wire reel to move upward, thus maintaining the height of both ends of the wire feeding track unchanged and preventing excessive stretching and strain of the wire.

[0044] Specifically, the rust removal of welding wire includes the following contents:

[0045] When the distance sensor 3018 detects that the diameter of the welding wire is too large and exceeds the standard, the first motor 207 is turned off to stop driving the wire reel to rotate, and then the staff checks whether the diameter of the welding wire exceeds the standard or the surface is rusted. If the diameter exceeds the standard due to rust on the surface of the welding wire, the welding wire reel on the right is controlled to reel the rusty welding wire back, and then the two rust removal mechanisms are controlled to operate, and then the two welding wire reels are controlled to rotate again to transport the welding wire. During the transportation process, the two rust removal mechanisms remove the rust on the surface of the welding wire; when the rust removal mechanism on the right is in operation, sandpaper wheels are pre-installed on the two third transmission shafts 406, one for reeling and the other for unloading, and then the two second cylinders 402 are controlled to drive the twelfth mounting plate 403 to move upward, and the twelfth mounting plate 403 drives the two thirteenth mounting plates 403 to move upward. The mounting plate 404 moves upward, and the two thirteenth mounting plates 404 drive the corresponding third motor 405 and the third transmission shaft 406 to move upward, so that the sandpaper covers the welding wire and wraps the lower part of the outer surface of the welding wire. The upper part of the welding wire is against the abutment plate with a groove set in the middle of the lower left side of the eleventh mounting plate 401 to prevent the welding wire from being pressed and causing tensile strain. Afterwards, when the welding wire is conveyed, the rust on the lower part of its outer surface is ground off by the sandpaper and falls into the collection box 408 below. The third motor 405 is regularly controlled to start and drive the third transmission shaft 406 to rotate to reel in the sandpaper, so that the sandpaper wrapped around the welding wire can be replaced regularly to prevent the sandpaper from being worn flat after being used for a long time and affecting the rust removal effect. Similarly, when the rust removal mechanism on the left is in operation, the rust on the upper part of the outer surface of the welding wire is ground off.
