The third lifter 130c has an intermediate transition function, and for an unqualified intermediate product obtained by assembling some parts of the hydrogen fuel cell, the third lifter 130c can reduce the time for the unqualified intermediate product to reach the maintenance platform 200, thereby improving the maintenance efficiency.
The third lifters 130c are provided in plural, and at least one assembling station is provided between two adjacent third lifters 130 c. By providing the plurality of third elevators 130c, the unqualified intermediate product can reach the lower-layer conveyor line 120 as soon as possible by the third elevators 130c nearby, and the maintenance efficiency can be further improved. In other embodiments, the number of the third elevators 130c may be only 1.
Specifically, in this embodiment, there are 6 third elevators 130c, and the 6 third elevators 130c are respectively located between the second automatic station 302 and the third automatic station 303, between the fourth automatic station 304 and the fifth automatic station 305, between the eighth automatic station 308 and the first manual station 101, between the tenth automatic station 3010 and the first semi-automatic station 201, between the twelfth automatic station 3012 and the thirteenth automatic station 3013, between the fourteenth automatic station 3014, between the fifteenth automatic station 3015 and the second semi-automatic station 202.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
