Dispensing film covering stringing method and tool assembly

Abstract

This invention relates to the field of photovoltaic module technology, specifically disclosing a dispensing and coating method for stringing solar cells and a tooling assembly. The dispensing and coating method includes the following steps: placing a tooling assembly on the surface of a solar cell; wherein the tooling assembly includes at least two positioning slots and two fixing slots, with the two positioning slots corresponding to and communicating with the two fixing slots; placing a solder ribbon into the tooling assembly on the solar cell, the solder ribbon being positioned by the positioning slots of the tooling assembly, and the solder ribbon adhering to the grid lines on the surface of the solar cell, wherein the end of the solder ribbon is located in the fixing slot; dispensing adhesive onto the end of the solder ribbon; removing the tooling assembly from the surface of the solar cell; and attaching a film strip to the surface of the solar cell to fix the solder ribbon to the surface of the solar cell. This method achieves double fixation between the solder ribbon and the solar cell through dispensing and the film strip, thereby greatly improving the connection tightness and reducing the probability of poor contact or separation between the solder ribbon and the grid lines on the solar cell, ensuring the conductivity efficiency of the solar cell string.
