[0036] Please refer to Figure 1-Figure 3 A fuel tank air tightness test device includes a plurality of mounting plates 1, a test bench 2, an air intake pipe 3, a transfer mechanism 4, a first conveyor belt 5 and a second conveyor belt 6.

[0037] like Figure 1 As shown, the first conveyor belt 5 is laid in the factory, and the oil tanks are placed on several mounting plates 1 respectively, and are transferred to one side of the transfer mechanism 4 through the first conveyor belt 5. The transfer mechanism 4 transfers the mounting plate 1 with the oil tank to the work station 21.

[0038] Specifically, Figure 1 As shown, a limiting groove 1a is provided on the top of the mounting plate 1. When the oil tank is placed in the limiting groove 1a, its side wall abuts against the limiting groove 1a.
