Description

Technical Field

[0001] The utility model relates to the technical field of wire-laying structures, in particular to a wire-laying structure for a string welding machine. Background Art

[0002] The stringer is a welding equipment that uses a mechanical transmission mechanism to transport battery cells and uses the high-temperature gas of the hot air pipe on the heated base plate to weld the battery cells. The stringer needs to use round wire welding ribbon during welding. When the stringer is working, it unwinds the round wire welding ribbon wound on the reel.

[0003] In order to improve the pay-off stability of the round wire welding strip when the stringer is working, the prior art has made many improvements to the pay-off structure of the stringer, such as the patent with the publication number CN219669760U, which discloses a pay-off structure of the stringer, including a bracket, a pay-off device, and a wire-passing plate; a mounting plate is provided on the rear side of the bracket, and a pay-off device is installed on the right side of the mounting plate, and a total of five groups of the pay-off devices are provided; upper guide wheels and lower guide wheels are also provided on the left and right sides of the mounting plate, and the upper guide wheel is located at an obliquely upper position of the lower guide wheel; the upper guide wheel corresponds to the three groups of pay-off devices above the mounting plate, and is used to receive the welding strips led out of the three groups of pay-off devices; the lower guide wheel corresponds to the two groups of pay-off devices below the mounting plate, and is used to receive the welding strips led out of the two groups of pay-off devices; the material storage device is located below the wire-passing plate; the utility model can complete the pay-off operation of five welding strips at the same time; at the same time, it can keep the wire motor in a state of continuous uniform rotation, so as not to cause the pay-off wheel to rotate autonomously and disorderly, thereby ensuring that the welding strip will not fall off.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

Therefore, the stringer needs to be shut down for a long time, which reduces the welding efficiency of the stringer. Therefore, there is an urgent need in this field to improve the pay-off structure of the stringer to solve the defects of the prior art. Utility Model Content
