This application provides a back-contact battery string packaging process, in which a front glass with a skin film on its upper surface is transported to an assembly station; a transport mechanism picks up the battery string from the previous process and constrains it to a straight position, and the transport mechanism transfers the battery string to the assembly station, so that the blue film side of the battery string is attached to the skin film. The transport mechanism constrains the battery string to a straight position during the transfer process; a heating element heats the battery string at the assembly station to fix the battery string to the skin film; the transport mechanism returns to the previous process to pick up the next battery string; after the battery string at the assembly station reaches a predetermined number, busbars are welded to each battery string to interconnect the battery strings. This application uses a conveying mechanism to press the battery string, which is constrained to a flat state, against the skin membrane. Then, a heating element heats each cell in the battery string, causing the skin membrane beneath the cell to melt and thus fix the cell to the skin membrane. After the conveying mechanism releases the battery string, due to the constraint of the skin membrane on the cell, the warping deformation of each cell in the battery string is no more than 1mm, which meets the parameter requirements of photovoltaic modules.
