5. The head pre-spot welding device according to claim 1, wherein the first spot welding member (111) and the third spot welding member (131) are the same in number, the second spot welding member (121) and the fourth spot welding member (141) are the same in number, and each of the first spot welding member (111) and each of the third spot welding member (131) are disposed opposite to each other in the longitudinal direction, and each of the second spot welding member (121) and each of the fourth spot welding member (141) are disposed opposite to each other in the width direction.
6. The top cover pre-spot welding device of claim 1, further comprising a reset mechanism (400), the reset mechanism (400) configured to move the battery along a direction of the first side (110) toward the third side (130) and a direction of the second side (120) toward the fourth side (140) to move the battery to an initial position.
7. The roof pre-spot welding apparatus of claim 6, wherein the reset mechanism (400) comprises a first reset cylinder and a second reset cylinder;
wherein the first reset cylinder can drive the welding assembly to move along the direction of the first side (110) towards the third side (130), and the second reset cylinder can drive the welding assembly to move along the direction of the second side (120) towards the fourth side (140) so as to move the battery to the initial position.
8.
