Automatic assembling system of proton exchange membrane fuel cell stacks

Abstract

The invention discloses an automatic assembling system of proton exchange membrane fuel cell stacks. The automatic assembling system mainly comprises a rack, an assembly delivery mechanism, an assembly pick-up mechanism, a stack assembling mechanism, an on-line sealing detector, a displacement control mechanism, transverse limiting mechanisms, a stack ejecting mechanism, a stack transfer mechanism and a corresponding control system. With the adoption of the automatic assembling system, continuous and automatic assembling and on-line sealing detection of the fuel cell stacks can be realized; no locating pin and controllable displacement assembling modes are realized in an assembling process; and the problems that locating pin drawing damages the assembling quality of the stacks and the overall performance of the stacks is low due to an assembling displacement deviation are avoided. According to the automatic assembling system of the stacks, automatic assembling of the stacks in different models can be realized; the assembling reliability and the assembling consistency of the stacks are ensured; and the assembling efficiency of the stacks is improved.

Description

technical field [0001] The invention relates to an automation system, in particular to an automatic assembly system for a proton exchange membrane fuel cell stack. technical background [0002] A fuel cell is different from a battery in the conventional sense in terms of principle and structure. It is a device that directly converts the chemical energy stored in fuel and oxidant into electrical energy electrochemically. Today, as environmental pollution becomes more and more serious and fossil energy becomes more and more tense, human beings urgently need a new sustainable and non-polluting energy source to replace the existing energy structure. Due to its environmental friendliness and high conversion efficiency, fuel cells are expected to be used as an alternative energy source for fossil fuels, and are increasingly valued by governments and energy and power manufacturers around the world. There are many classifications of fuel cells, usually classified according to the e...

Problems solved by technology

However, it is difficult for this device to accurately ensure the consistency between the center of the stack and the axis of the pressure-adjustable device by using the lifting platform, and it is easy to skew the stack and damage the stack components

[0009] It can be seen from the above patents that the existing fuel cell stack assembly mechanisms generally have shortcomings such as low assembly efficiency, large manual operation errors, low repeatability, and difficulty in effectively controlling the compression displacement of the stack.
