Description

Membrane electrode dispensing and attaching platform

Technical Field

The utility model belongs to the field of membrane electrode production and manufacturing of hydrogen fuel cells, and particularly relates to the field of membrane electrode GDL dispensing and manufacturing.

Background

At present, all OEMs continuously break through in the volume power density of the electric pile, which also makes the specific surface area requirement of the membrane electrode of the core part of the fuel continuously increase. Aiming at the product requirements of higher and higher precision, in order to increase the specific surface area of the product and increase the utilization rate of expensive raw materials, the GDL laminating precision is also improved besides the precision of the slitting process of the raw materials in the process engineering.

In the current assembly method of the membrane electrode assembly of the fuel cell in the market, the GDL is fixed on a 5-layer CCM in a mode of dispensing, hot pressing, laminating and the like, and finally the MEA with a seven-layer structure is obtained. The CCM frame adopts PEN with the thickness of 10-100um, the material is thin and soft, the material used by the proton exchange membrane is only 8-15um, and the CCM frame is extremely easy to be influenced by the temperature and the humidity of the air environment. So that the conditions of swelling, pollution, deformation, damage and the like are easy to occur in the production process. Particularly, the high temperature which is inevitably caused in the hot pressing assembly process can influence the assembly, the position accuracy is not well controlled, and the product performance is easily reduced and even scrapped.

Disclosure of Invention

The utility model aims to: aiming at the technical problems that in the prior art, the temperature in the hot pressing process is difficult to control, CCM is easy to swell and deform, GDL is assembled and the like, the applicant designs the technical scheme of the utility model.

The technical scheme is as follows: in order to achieve the above purpose, the utility model provides a membrane electrode dispensing and attaching platform, which comprises an operation table, wherein the upper end surface of the operation table is set to be an operation plane. The utility model discloses a patch panel, including the patch panel, the patch panel is provided with the fixed plate, the fixed plate upper end sets up the patch bottom plate, the patch bottom plate moves around on the fixed plate, the patch bottom plate is hollow structure, and patch bottom plate two points set up vacuum interface, patch bottom plate up end sets up a plurality of vacuum absorption holes, the four corners department of patch bottom plate sets up the locating pin, a plurality of vacuum absorption holes have also been set up on the operation plane, both sides set up spacing post on the operation plane.

The patch bottom plate is provided with a locating plate, the four corners of the locating plate are provided with pin holes, and the pin holes correspond to the locating pins.

Two gas diffusion layers are arranged on the positioning plate, and a CCM layer is arranged between the two gas diffusion layers.

The positioning plate is provided with scale marks (such as positioning bosses and laser positioning identification lines) of a positioning assembly, and the bottom plate is fixed on the workbench and needs to be glued. The positioning plate can be fixed on the mechanical arm to perform the action of positioning and transferring the component.

When in actual work, the vacuum valve is opened, and the GDL layer is adsorbed on the positioning plate to prevent wrinkles. The GDL layer which does not participate in the operation yet can be directly placed on the operation plane, and the GDL layer is fixedly placed through the vacuum adsorption holes so as to prevent folding wrinkles.

The beneficial effects are that: compared with the prior art, the utility model has the beneficial effects that:

the device provided by the utility model is convenient for positioning the CCM and the GDL, ensures that the CCM membrane is not wrinkled when the GDL is assembled, improves the utilization rate of raw materials, improves the bonding precision of the GDL, and effectively reduces the workload when the membrane is bonded.
