Fuel cell bipolar plate welding production process

Abstract

The invention discloses a fuel cell bipolar plate welding production process. The process comprises single pole plate feeding, hydrogen pole plate welding, oxygen pole plate welding, bipolar plate transferring, manual spot detecting, air tightness detecting, and bipolar plate discharging; the single pole plate feeding is that two pieces of single pole plates, namely the hydrogen pole single pole plate and the oxygen pole single pole plate are placed on bipolar plate transferring in pair; the hydrogen pole single pole plate and the oxygen pole single pole plate are welded when reaching the poleplate welding station, and after welding, the hydrogen pole single pole plate and the oxygen pole single pole plate are compounded into a bipolar plate to be transferred to bipolar plate transferringagain; and the bipolar plate is sent to the manual spot detecting station and the air tightness detecting station through bipolar plate transferring, and the bipolar plate subjected to air tightnessdetection is packaged at the bipolar plate discharging position. According to the process, suction mechanical hands are arranged at multiple places including front end position of a speed chain, the welding position, the tail end position of the speed chain, the air tightness detection feeding position and the air tightness detection discharging position, the bipolar plate is packaged through thedischarging mechanical hands after the welding and air tightness detection processes are completed, the whole production line is completed by matching an electric structure with a fully-automatic mechanical structure.

Description

technical field [0001] The invention relates to the technical field of new energy fuel bipolar plates, in particular to a fuel cell bipolar plate welding production process. Background technique [0002] As a new type of fuel that can replace gasoline and diesel, new energy fuel cells have received extensive attention and technological improvement as an alternative product under the combined effects of limited oil resources and unfavorable environmental factors, especially hydrogen fuel. Battery technology, because it does not produce any pollutants, is the vane of new energy development. [0003] At present, hydrogen fuel cells are mainly realized by stacking bipolar plates to increase power. The welding process of two unipolar plates is the key factor determining the performance of hydrogen fuel cells. The degree of automation is not high, especially in the whole process of unipolar plate on-line, welding and bipolar plate off-line cannot achieve continuous transfer and s...

[0003] At present, hydrogen fuel cells are mainly realized by stacking bipolar plates to increase power. The welding process of two unipolar plates is the key factor determining the performance of hydrogen fuel cells. The degree of automation is not high, especially in the whole process of unipolar plate on-line, welding and bipolar plate off-line cannot achieve continuous transfer and separate transfer of trays in different positions, usually requires manual or auxiliary equipment to help complete this action, so that The extended time of this action consumes a lot of manpower, affects the continuity of the entire welding production line, increases the production cost, reduces the production efficiency, and cannot meet the needs of batch bipolar plate production.
