Specific examples of the bipolar plate generating mechanism, the spot sealer and curing mechanism, and the air tightness detecting mechanism in the bipolar plate automatic synthesis system are given below.

Example 1

As shown in fig. 1 (a) to 1 (e), the present embodiment provides a first feeding device 10. The first feeding device 10 and the second feeding device 30 have the same structure, the first feeding device 10 is perpendicular to the output direction of the second feeding device 30, and the first feeding device 10 comprises a first conveying component 11, a feeding table 12 and a third conveying component 13.

The loading waiting station 415 is used for temporarily storing the second polar plate output by the second loading device 30, so as to prepare the fourth sucker 422 for rotating and carrying. As a most preferred option, the fourth suction cup 422 is turned 180 degrees in the vertical feeding direction and then turned 90 degrees in the horizontal direction over the loading waiting station 415 to align with the bonding station 411 in the loading direction. The primary carrying of the second polar plate is realized in the rotation process, and the second polar plate is further carried by being matched with the third sucker 421, so that the second feeding device 30 for inputting the second polar plate is tightly butted with the bonding device 40, and the production space is saved.
