Abstract: An assembly device includes a supporting member configured to support an end cap of a battery cell and a pressing-down mechanism arranged above the supporting member. The pressing-down mechanism is configured to press down a housing of the battery cell to enable the housing to fit with the end cap, so that the end cap closes off an opening of the housing.

Abstract: A welding method includes placing a housing covered with an end cap into a jig, where a clearance structure is created on the jig and available for exposing a target weld zone between the end cap and the housing, and the target weld zone includes a first target weld zone section and a second target weld zone section located on two opposite sides of the end cap respectively; and moving the jig to a first welding station of a welding device; welding, by a first welding head of the welding device, the first target weld zone section through the clearance structure; and welding, by a second welding head of the welding device, the second target weld zone section through the clearance structure. The first welding station is located between the first welding head and the second welding head.
