Technical Field

The present invention relates to an assembly jig, and more particularly to an assembly jig suitable for a fuel cell stack.

Background

A fuel cell is a chemical device that directly converts chemical energy of fuel into electrical energy, and is also called an electrochemical generator. It is a fourth power generation technology following hydroelectric power generation, thermal power generation and atomic power generation. Since the fuel cell converts part of gibbs free energy in chemical energy of fuel into electric energy through electrochemical reaction, the fuel cell is not limited by carnot cycle effect.

The stacks of the existing dye cells need to be stacked during assembly by manual or automated equipment. However, due to the complexity of the layers and construction, accessories are required for limited support during stack assembly. At present, the accessories can only be installed and guided in a single direction, and omnibearing limit cannot be realized, so that deviation occurs during assembly, and the final quality of a battery product is influenced.

The assembly jig suitable for the fuel cell stack for achieving the object of the present invention comprises a main substrate, wherein: the edge periphery of the main substrate is vertically provided with a plurality of limiting guide assemblies, the main substrate is also provided with a plurality of limiting assemblies, and one side of the main substrate is provided with a holding assembly.

Further, the assembly jig suitable for the fuel cell stack is characterized in that the limiting guide assembly is a limiting upright post, and one side of the bottom of the limiting upright post is connected with the periphery of the edge of the main substrate; or the bottom of the limiting upright post is connected with the periphery of the edge of the main substrate through a spring assembly.

Furthermore, the assembly jig for a fuel cell stack is provided, wherein the inner side of the limiting upright post is provided with a guide strip, or the inner side of the limiting upright post is provided with a guide groove.

Furthermore, the assembly jig suitable for the fuel cell stack is characterized in that the limiting assembly is a rotary sleeve, a plurality of mounting grooves are distributed on the main substrate, and the rotary sleeve is arranged in the mounting grooves and extends out of the mounting grooves.

Furthermore, the above mentioned assembling jig for fuel cell stack is characterized in that the rotary sleeve is transversely provided with a plurality of height adjusting holes, the side surface of the main substrate is provided with positioning holes, sleeve limiting components are arranged in the height adjusting holes and the positioning holes in a penetrating manner, and the sleeve limiting components are bolts.

Still further, the above-mentioned assembly jig suitable for fuel cell pile, wherein, the subassembly of gripping is the handle, the handle both ends are provided with the location strip, the location strip passes through set screw and installs in one side of main substrate.

The technical scheme of the invention has the following advantages:

1. the limiting guide can be realized by adopting the mutual matching of the limiting upright posts, so that all components can be conveniently stacked and combined in sequence, and finally, a complete fuel cell stack is formed.

2. Be equipped with independent rotation type sleeve, can adjust spacing height to different cell stack models, it is spacing to be convenient for assemble.

3. The assembly efficiency is guaranteed, and meanwhile, assembly errors cannot occur.

4. The whole structure is simple, and the assembly and the use are easy.

Objects, advantages and features of the present invention will be illustrated and explained by the following non-restrictive description of preferred embodiments thereof, given by way of example only with reference to the accompanying drawings.
