Holding tool device for automatically stacking fuel cell stacks

Abstract

The invention discloses a holding tool device for automatically stacking fuel cell stacks. The device is characterized in that the device comprises a bottom plate which is used for placing an electricpile and a back plate which is fixedly connected to the bottom plate; the bottom plate is provided with a plurality of fixed base columns which are transversely arranged at intervals in front of theback plate; the back plate is provided with a first guide mechanism which can be transversely opened and closed and is matched with the two transverse sides of the galvanic pile for limiting; the first guide mechanism is provided with a second guide mechanism capable of longitudinally moving in front of the fixed base column, the second guide mechanism, the fixed base column and the two longitudinal sides of the electric pile are matched for limiting, and the bottom plate is further provided with a pressing mechanism capable of vertically pressing the electric pile. The transverse size of theelectric pile is controlled and kept through automatic opening and closing of the first guide mechanism, then the longitudinal size between the electric pile and the fixed base column is controlled through movement of the second guide mechanism, the electric pile is vertically pre-pressed and limited through the pressing mechanism after stacking is completed, and the electric pile can be stably transferred to a pressing station.

Description

technical field [0001] The invention relates to stacking of fuel cell stacks, in particular to a holding device for automatic stacking of fuel cell stacks. Background technique [0002] At present, most fuel cell stacks are stacked manually. The specific operation method is to manually install the material guide and limit device in place before stacking. The specified order of stacking is stacked one by one. Considering the large number of stacked materials such as membrane electrodes and bipolar plates, and the high requirements for their mutual positions, the gap adjustment of the guide limit device is particularly important, and the process of manually adjusting the guide device is cumbersome, time-consuming, and manually adjusted. Higher disadvantages are required. [0003] Chinese patent CN104835978A, titled Proton Exchange Membrane Fuel Cell Stack Automatic Assembly System, proposes a fuel cell stack automatic assembly process system from material assembly, compressi...

Problems solved by technology

The method and device do not realize the automatic stacking of stack materials, and the use of positioning holes in the materials requires taking out the positioning mechanism after the materials are stacked. The positioning mechanism is generally small in diameter and it is difficult to ensure the accuracy of straightness. At the same time, it is difficult to realize the automatic stacking of materials in the internal positioning method.

[0005] Chinese patent CN105304925A is named as a fuel cell stack assembly device. The fuel cell stack is positioned by the outer contour of the material, and is composed of a limiting part, a fixed frame and a bottom plate to ensure the stacking accuracy, but the limiting device of the device needs to be manually Installation and adjustment, not suitable for automated production assembly
