Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0032] Such as figure 1 As shown, this embodiment provides a straightening device for a metal plate of a fuel cell, including a grasping module, an attitude adjustment module and a measurement module.

[0033] The gripping module includes a vacuum chuck 8 and metal connectors (not shown in the figure). The vacuum chuck 8 is used to grab the metal pole plate 9 . The metal connector is arranged on one side of the vacuum chuck 8, and when the vacuum chuck 8 sucks the metal pole plate 9, the metal pole plate 9 contacts the metal connector.

[0034] The measurement module includes a hou...

Abstract

The invention relates to a guiding device and method for a fuel cell metal polar plate. The guiding device comprises a grabbing module, a posture adjusting module and a measuring module, wherein the grabbing module comprises a vacuum suction cup and a metal connecting piece, and the metal connecting piece is arranged at one side end of the vacuum suction cup; the posture adjusting module is connected with the grabbing module and used for adjusting the posture of the grabbed metal pole plate, the measuring module comprises four conductive contact lines and four ohmmeters, one ends of the four conductive contact lines are connected with the posture adjusting module, and the other ends of the four conductive contact lines make contact with the four side edges of the grabbed metal pole plate correspondingly. And each ohmmeter is used for measuring the resistance value of the connected conductive contact line from the end part connected with the posture adjusting module to the end part contacted with the side edge of the metal pole plate. Compared with the prior art, through the design of the conductive contact line, by measuring the effective resistance value on the conductive contact line, whether the metal pole plate is in a horizontal state or not is conveniently and rapidly judged, and then the metal pole plate is adjusted through the posture adjusting module to achieve correction of the metal pole plate.

Description

technical field [0001] The invention relates to the field of fuel cell assembly, in particular to a guiding device and method for metal pole plates of fuel cells. Background technique [0002] The proton exchange membrane fuel cell is a kind of electrochemistry that decomposes anode hydrogen into protons and electrons through a catalyst. device. [0003] Currently, the commonly used proton exchange membrane fuel cell assembly method mainly adopts a laminated structure, which is used to realize reliable reactant sealing of each layer. In the existing stacking method, a mechanical arm is used to stack metal plates one by one. However, during the stacking process, the metal plates are not aligned with each other, so that there is a deflection or offset between the stacked metal plates, which leads to a decrease in the overall power density of the fuel cell stack and a decrease in the width of the sealed structure. Increase. If inspection and calibration are performed manual...
