AI Technical Summary

Technical Problem

The existing single-piece dispensing equipment for fuel cell membrane electrode gas diffusion layer is required to replace the tool mold and adjust the procedure when it is produced in small batches or non-standard versions, resulting in waste of manpower and financial resources. At the same time, the positioning is inaccurate and the sheet is difficult to retrieve, which is easy to damage the gas diffusion layer.

Method used

A device including a base platform, a movable countertop and a positioning plate is designed. Through the coordination of the positioning holes and the positioning columns and the elastically retractable structure, the precise positioning and dispensing of the gas diffusion layer is realized, the sheeting process is simplified, and the gas diffusion layer of different shapes is adapted.

Benefits of technology

It improves the positioning accuracy of the dispensing process, simplifies the operation process, reduces manual operation errors and damage, and is suitable for small batch production and non-standard version gas diffusion layer packaging.

Abstract

The utility model discloses a device for dispensing a single piece of a fuel cell membrane electrode gas diffusion layer, comprising: a base platform, with a top block in the middle of the top surface, four positioning columns at the four corners, and the positioning columns are also provided with an elastic and retractable structure; a movable table, the top surface is used to place the gas diffusion layer to be dispensed when in use; a positioning plate, with four positioning holes at the four corners for positioning in cooperation with the positioning columns, a positioning slot in the middle, and a circle of convex edges on the inner side wall of the positioning slot for erecting the movable table; when in use, the positioning slot is directly opposite to the top block, and by pressing down the positioning plate, the top block can push the movable table out of the positioning slot. The present application replaces the time-consuming and labor-intensive method of replacing the knife die with a simple tooling. It improves positioning accuracy, simplifies the film taking process, and prevents damage to the GDL during manual operation. It also has its own positioning angle, so dispensing can be performed when encountering some rounded corner GDLs.
