Abstract

The utility model discloses a rapid fastener specially used for leakage detecting of a bipolar plate of a fuel cell. The rapid fastener comprises a servo motor and compacted punch holder and die holder which are driven by the servo motor. The servo motor is fixed on the surface of a fixed plate through fixed columns. The fixed plate is arranged above the die holder through guide rail columns and is connected fixedly with the die holder. The punch holder is arranged between the fixed plate and the die holder and slides along the guide rail columns. A screw of the servo motor rotates to control the movement position of the punch holder. The rapid fastener can detect leakage of multiple bipolar plates all at once. Because the servo motor drives a leakage detecting die fastening, the detection speed can be rapider.

Description

A kind of fuel battery double plates leak detection Special rapid fastening device
Technical field
The utility model relates to a kind of fuel battery double plates leak detection Special rapid fastening device.
Background technology
Fuel cell (PEMFC) technology is to utilize the most efficient means of Hydrogen Energy.Fuel cell is the device that the chemical energy of hydrogen is converted into electric energy, has advantages of that the high and low noise of efficiency, zero pollutes, and is playing the part of more and more important role in present day society.Fuel cell need to be assembled into pile by the mode of series connection by multiple cells conventionally, and main composition parts have bipolar plates, membrane electrode, end plate and securing member etc., and wherein the gas leakage of bipolar plates and membrane electrode is determining performance and the life-span of fuel cell pile.Therefore how convenient and swift and on a large scale industrialization to detect double-polar plate gas leakage extremely important.Traditional bipolar plates leakage detection apparatus is to be put together by fastening bolt and leak detection mould, hunts leak, and automaticity is not high, belongs to pure manual operations, loses time, and inefficiency, is unfavorable for the development of fuel cell industrialization.
Publication number CN101174693 discloses a kind of fuel cell membrane electrode and double-polar plate gas leakage checking device, for solving the gas leakage performance that detects all kinds of difform planes or non-planar material, the technological means adopting is the upper and lower removable air pressure storehouse with four guide rails to be designed to removable, changes different air pressure storehouses according to difform plane or non-planar material.In order to make the surperficial pressurized of measured sample even, in device, be provided with a pressure buffer storehouse with grid structure in addition.Disclosed these technological means of the disclosure file can only detect separately bipolar plates sampling, cannot realize scale multiple bipolar plates are detected.
Publication number CN101069316 discloses a kind of fuel cell system and method for inspecting gas leakage of same thereof, the main order ground of the disclosure content is in order to detect after fuel cell impermeability, do not allow inspection gas sneak in fuel cell, mix with fuel gas, reduce the performance of fuel cell.This file has adopted multiple technologies means in order to reach this purpose: in the stream to fuel cell system supply response gas, form the enclosure space that does not comprise fuel cell; In inspection gas discharge system, be provided with pressure reducing mechanism, for inspection gas is depressured under authorised pressure; In inspection gas discharge system, be provided with the recovering mechanism that checks gas for reclaiming.The open of this file do not solve and how the bipolar plate tightness of fuel cell hunted leak fast, and complicated structure, needs a large amount of manual operationss, and efficiency is lower.
Publication number CN202379140U discloses a kind of leak tester of Packaging Bottle, belong to the field to Packaging Bottle airtight test, the technical matters solving is to provide and a kind ofly can detects the Packaging Bottle leak tester whether Packaging Bottle leaks, in order to address this problem, the disclosed scheme of this file is that Packaging Bottle sealing is divided into bottle interior sealed cavity and bottle external seal cavity, then to pressurizeing in bottle, and bottle outer air is extracted out and formed vacuum state, be to determine whether Packaging Bottle has leakage by Vacuum Pressure device for detecting difference.The mode of this file disclosure detection draught head is carried out the impermeability of testing product, but can not hunt leak to multiple products simultaneously, bipolar plates belongs to planar materials simultaneously, in disclosure, also the impermeability of planar products is not detected and makes any technology enlightenment.
To sum up, present bipolar plates leakage detection apparatus only can be put leakage detection apparatus and single bipolar plates to hunt leak separately together, and automaticity is not high, needs a large amount of manual operationss, loses time, and inefficiency, is unfavorable for the development of fuel cell industrialization.
Utility model content
Utility model object: the utility model object is for the deficiencies in the prior art, and a kind of fuel battery double plates leak detection Special rapid fastening device that can disposablely simultaneously detect multi-disc bipolar plates is provided.
Technical scheme: fuel battery double plates described in the utility model leak detection Special rapid fastening device, comprises servomotor and by the fastening train wheel bridge of driven by servomotor and lower plate; Described servomotor is fixedly installed on the surface of fixed head by fixed leg, described fixed head is arranged on described lower plate top by guide rail column is fixedly connected with lower plate; Described train wheel bridge is arranged between described fixed head and described lower plate, slides along described guide rail column; The movement position of train wheel bridge described in the screw mandrel rotation extension and contraction control of described servomotor.
When specific works, can be by multiple the leak detection mould that is provided with bipolar plates to be checked stacked being placed between train wheel bridge and lower plate, motion after servomotor energising, rotary screw rod makes train wheel bridge arrive the position of setting, guide rail column mainly plays positioning and guiding effect, train wheel bridge is moved along guide rail column, in the time compressing leak detection mould, distance between the accurate positioning control upper and lower plates of the servomotor mould that makes to hunt leak is stressed evenly, prevent in leak detection process because of the leak outside generation of phenomenon of mould that causes hunting leak of mould unbalance stress, impact leak detection result.
As preferably, described guide rail column is 4, is arranged on four angles place of fixed head and lower plate.
As preferably, described fuel battery double plates leak detection Special rapid fastening device also comprises PLC controller, and described PLC controller is connected with described servomotor, the unlatching of control servomotor, closes.PLC controller is connected with servomotor, can by predefined parameter control servomotor unlatching, close, further control the position that train wheel bridge arrives.
Beneficial effect: the motion of (1) the utility model by train wheel bridge can be simultaneously fastening by being placed on multiple leak detection mould between train wheel bridge and lower plate, reaches the object of one-time detection multi-disc double-polar plate gas leakage; Use motor to drive simultaneously and compress leak detection mould, can realize fast detecting; (2) the utility model compresses leak detection mould by driven by servomotor train wheel bridge, can control accurately the position of train wheel bridge, ensure that whole leak detection mould surrounding is stressed evenly, can not cause the uneven phenomenon that leaks outside that produces of leak detection mould local pressure, affect final leak detection result; By the lead motion of train wheel bridge of guide rail, can make train wheel bridge, multiple leak detection moulds can be tightened together, the mould that prevents from hunting leak slides to cause and leaks outside in leak detection process; (3) the utility model is connected with servomotor by PLC controller, and control leak detection process that can robotization, operates without supernumerary's work, has improved accuracy rate and the work efficiency of hunting leak, and is convenient to industrialization and develops on a large scale.
