[0003] In the prior art, there are two ways to cut the solder tape, namely the up-and-down cutter cutting method and the left-and-right cutter cutting method; the left-and-right cutter cutting method can reduce the longitudinal height of the solder tape cutting mechanism, so that the solder tape cutting mechanism can be arranged closer to the transmission line for laying the solder tape, thus enabling the solder tape traction mechanism to save a certain amount of time in pulling the solder tape, and to a certain extent improving the laying efficiency. Therefore, the application of the left-and-right cutter cutting method is becoming more and more common; however, when the left-and-right cutter mechanism cuts the solder tape and the solder tape clamping and laying mechanism clamps and pulls the solder tape, there will be a certain height difference in the height plane when observing the solder tape, and there will be a certain risk of warping when the solder tape clamping and laying mechanism lays the solder tape on the battery wafer; therefore, a solder tape cutting mechanism with a guiding function and a string welding machine are provided to solve the above problems.
