Technical Field

The utility model relates to a hydrogen fuel cell technical field especially relates to a tool that is used for two-sided spraying of hydrogen fuel cell's proton exchange membrane.

Background

Hydrogen fuel cells have been widely used in recent years as an environmentally friendly, efficient energy conversion technology. The membrane electrode is an important component of hydrogen fuel cell, and is a component with three-in-one structure, and is formed from diffusion layer, catalytic layer and proton exchange membrane. The proton exchange membrane is sprayed with slurried catalyst, dried and pressed into a frame protective frame and diffusion carbon paper to form a membrane electrode, wherein catalyst slurry with designed loading capacity is required to be accurately sprayed on the front side and the back side of the proton exchange membrane. Fixing the proton exchange membrane on the workbench of the spraying machine through the adsorption platform, peeling the proton exchange membrane from the adsorption platform and turning to the other side by a skilled operator after the spraying is finished, and continuing the spraying of the other side.

Because the proton exchange membrane in the prior art is extremely thin, membrane wrinkles are easily generated in the process of peeling and turning the proton exchange membrane after the first surface is sprayed, and front and back positioning deviations are easily generated, so that poor sealing and packaging dislocation caused by the wrinkles are often generated after a product is manufactured.

the utility model provides a tool that is used for two-sided spraying of proton exchange membrane of hydrogen fuel cell, includes workstation, punch holder and lower plate, workstation top center department installs and adsorbs the bottom plate, and adsorbs bottom plate and workstation parallel arrangement, punch holder one side both ends all are equipped with the coupling mechanism who is used for connecting the lower plate, the notch that runs through is all seted up to punch holder and lower plate side, and the lower plate top is provided with from the adhesion disc and level setting, the proton membrane of looks adaptation is provided with at the adhesion disc top.

As a further aspect of the present invention, the connecting mechanism includes a connecting hinge, and one end of the connecting hinge is installed on one side of the upper clamp plate, and the other end of the connecting hinge is installed on one side of the lower clamp plate.

As a further proposal of the utility model, the upper clamp plate and the lower clamp plate are all provided with a grab.

The utility model has the advantages that:

1. the utility model discloses, only use an equipment can accomplish the two-sided spraying of proton exchange membrane, the middle proton exchange membrane that does not need to turn over of dress process that turns over, avoid the manual work to turn over membrane fold, pollution, the secondary positioning error that produces easily in the process, reduce the finished product defective rate by a wide margin, tool simple structure is reliable, maintains the convenience, and each part can be convenient change or maintain.

Drawings

Fig. 1 is a schematic structural diagram of a jig for double-sided spraying of a proton exchange membrane of a hydrogen fuel cell according to the present invention.

In the figure: 1. an adsorption base plate; 2. a lower splint; 3. an upper splint; 4. connecting a hinge; 5. a self-adhesive sheet; 6. a proton membrane.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1, a tool that is used for two-sided spraying of proton exchange membrane of hydrogen fuel cell, comprises a workbench, punch holder 3 and lower plate 2, workstation top center department installs and adsorbs bottom plate 1, and adsorbs bottom plate 1 and workstation parallel arrangement, 3 one side both ends of punch holder all are equipped with the coupling mechanism who is used for connecting lower plate 2, the notch that runs through is all seted up to

punch holder

3 and 2 sides of lower plate, and 2 tops of lower plate are provided with from bonding die 5 and level setting, from bonding die 5 tops is provided with the proton membrane 6 of looks adaptation.

Furthermore, the connecting mechanism comprises a connecting hinge 4, one end of the connecting hinge 4 is arranged on one side of the upper clamping plate 3, and the other end of the connecting hinge 4 is arranged on one side of the lower clamping plate 2.

Furthermore, hand grips are arranged on one sides of the upper clamping plate 3 and the lower clamping plate 2.

The working principle is as follows: in actual use, first, the first step: on putting into the adsorption bottom plate 1 to the punch holder 3 and the lower plate 2 of tool, the self-adhesive department and the coplanar of the top surface of adsorption bottom plate 1 and lower plate 2, the overall dimension of adsorption bottom plate 1 is unanimous with the notch size of tool lower plate 2, plays the horizontal direction positioning action, the second step: the proton membrane 6 that will need the spraying when the punch holder 3 of tool and punch holder 2 are in the open mode is put and is pasted on the self-adhesion piece 5 of

punch holder

2, and 6 edges of proton membrane align with the tool edge, and the third step: turn down lower plate 2, lean on dead weight or magnetism to inhale the device and make upper plate 3 and lower plate 2 closed, only leak the region that proton membrane 6 needs the spraying, start the spraying of the first face of proton membrane 6, the fourth step: after the first surface is sprayed, the upper clamping plate 3 and the lower clamping plate 2 together with the proton membrane 6 with the single surface sprayed in the middle are turned over by 180 degrees and placed on the adsorption bottom plate 1 again, and the other surface of the proton membrane 6 can be sprayed.
