step seven, the assembly bracket 23 of the battery assembly mechanism is reset, the first lifting seat 12 and the second lifting seat 13 of the battery positioning mechanism 1 move in opposite directions, the second positioning jig 142 is separated from the stud of the battery cell, the first positioning jig 141 is not separated from the battery shell, namely, the second positioning jig 142 is separated from the stud, a space is reserved for secondary pushing, the assembly nozzle 24 is convenient for pushing the insulating gasket in place, the bottom of the first positioning jig 141 is connected with the first lifting seat 12/the second lifting seat 13 through a spring, and therefore, after the first lifting seat 12 and the second lifting seat 13 move to the second jig to be separated from the stud, the first jig can still hold the battery shell under the action of the spring;
step eight, an assembly driving assembly 25 of the battery assembly mechanism drives an assembly bracket 23 to move for secondary pushing, and an assembly nozzle 24 pushes the insulating gasket to a design position so that the gasket is installed in the battery shell;
step nine, resetting the battery assembly mechanism, and continuously moving the first lifting seat 12 and the second lifting seat 13 of the battery positioning mechanism 1 in opposite directions, so that the first positioning jig 141 is separated from the battery shell;
and step ten, resetting the battery jacking mechanism 3, resetting the auxiliary positioning mechanism, conveying the battery away by the conveying mechanism, and simultaneously continuously conveying the battery to be processed between the battery jacking mechanism 3 and the battery positioning mechanism 1, so as to start the next assembly operation.
