Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen fuel cell manufacturing, and specifically relates to an adsorption jig. Background Technique

[0002] In the production of hydrogen fuel cells, the coating or spraying of proton exchange membranes is one of the key processes. When coating or spraying proton exchange membranes, it is necessary to adsorb and position the proton exchange membranes through an adsorption jig, and then perform coating or spraying operations on the surface of the proton exchange membranes. Since the proton exchange membrane is an ultra-thin and easily deformable material, when the existing adsorption jig adsorbs and positions the proton exchange membrane, there are problems of uneven adsorption and easy appearance of adsorption pits on the surface, thus affecting the performance and coating quality of the proton exchange membrane.

[0003] Moreover, when the existing proton exchange membrane is being coated, the heat conduction and heat dissipation capabilities of its adsorption jig are relatively poor, so that the adsorption jig cannot dissipate heat reliably, and thus the adsorption jig cannot provide a stable temperature environment for the coating or spraying process.

[0004] Therefore, there is an urgent need to develop an adsorption tool with uniform adsorption, no adsorption depression, and capable of providing a stable temperature environment. Summary of the Invention

[0005] In view of the above problems, the utility model provides an adsorption jig which has uniform adsorption for ultra-thin and easily deformable materials, does not cause adsorption depression, and can provide a stable temperature environment.

[0006] An adsorption jig, characterized in that it includes:

[0007] A microporous adsorption platform, the shape of which is imitated according to the ultra-thin material to be adsorbed;

[0008] A base, which includes a bottom plate and a profiling outer peripheral vertical plate. The profiling outer peripheral vertical plate is arranged on the upper surface of the bottom plate, and the profiling outer peripheral vertical plate encloses to form a placement cavity;

[0009] And a sealing ring;

[0010] The microporous adsorption platform is supported on the upper surface of the bottom plate and is located in the placement cavity. A sealing ring is sleeved on the outer periphery of the microporous adsorption platform, and the outer periphery of the sealing ring is closely attached to the inner wall of the profiling outer peripheral vertical plate. An adsorption hole is arranged outside the base for performing adsorption operations, and the base is made of a material with good heat conduction performance.

[0011] It is further characterized in that:

[0012] The upper surface of the microporous adsorption platform is flush with the upper plane of the outer peripheral vertical plate, ensuring that the ultra-thin material will not be damaged due to collision during operation;

[0013] The inner circumference of the sealing ring completely covers the outer peripheral side wall of the micro-porous adsorption platform to ensure that there is no air leakage;

[0014] On the upper surface of the base, a number of auxiliary support members are also laid at intervals. The setting of the auxiliary support members forms a transition air cavity between the bottom plate of the base and the micro-porous adsorption platform, and the transition air cavity is used to ensure uniform and reliable adsorption force;

[0015] One of the vertical plates of the profiling outer peripheral vertical plate is provided with the adsorption hole at the height direction position corresponding to the transition air cavity, and the adsorption hole is externally connected to a pipeline and a suction fan for reliable adsorption operation;

[0016] The auxiliary support member is a cross support member with a thickness, and all the cross support members are arranged in a matrix and welded at the corresponding position on the upper surface of the bottom plate;

[0017] The base is made of aluminum alloy;

[0018] The micro-porous adsorption platform is obtained by sintering micro-porous breathable alumina ceramics;

[0019] The cross support member is a copper part, which ensures sufficient and reliable heat conduction;

[0020] The aperture of the micro-porous adsorption platform is 5-50 um, and the distribution of the pores is bent and through in the sintered material, rather than the traditional parallel or vertical pores. The bent and through pores better reflect the hardness and support of the material, so it is more durable and has a longer service life;

[0021] The height of the sealing ring is 1-2 mm greater than the thickness of the micro-porous adsorption platform. The upper surface of the sealing ring is flush with the micro-porous adsorption platform, and the lower convex height of the lower end of the sealing ring is within the height space of the transition air cavity.

[0022] After adopting the present utility model, through the micro-porous adsorption platform of the micro-porous adsorption technology, the adsorption force is evenly distributed on the surface of the jig, ensuring that the material is evenly stressed during the adsorption process and there is no local deformation; and because the micro-porous adsorption platform forms hidden pores, there are no pores visible on the surface of the jig, effectively avoiding the direct influence of the pores on the surface of the material, thus preventing pits from appearing on the surface of the material, and because both the micro-porous adsorption platform and the base are made of materials with good heat conduction performance and a reasonable heat transfer path is designed, the temperature deviation on the surface of the jig is small, and a stable temperature environment can be provided.

[0029] An adsorption jig, as shown in Figures 1-4 , which includes a micro-hole adsorption platform 10, a base 20, a sealing ring 30, and several auxiliary support members;

[0030] The shape of the micro-hole adsorption platform 10 is profiled according to the ultra-thin material to be adsorbed;

[0031] The base 20 includes a bottom plate 21 and a profiling outer peripheral vertical plate 22; several auxiliary support members are fixedly arranged at intervals on the upper surface of the bottom plate 21. The arrangement of the auxiliary support members forms a transition air cavity 40 between the bottom plate 21 of the base 20 and the micro-hole adsorption platform 10, and the transition air cavity 40 is used to ensure uniform and reliable adsorption force;

[0032] The micro-hole adsorption platform 10 is supported on the upper surface formed by several auxiliary support members, and a sealing ring 30 is sleeved on the outer periphery of the micro-hole adsorption platform 10. The outer periphery of the sealing ring 30 is closely arranged against the inner wall of the profiling outer peripheral vertical plate 22. An adsorption hole 23 is provided at the position corresponding to the height direction of the transition air cavity on one of the vertical plates of the profiling outer peripheral vertical plate 22. The adsorption hole 23 is externally connected to a pipeline and an exhaust fan for reliable adsorption operation. Specifically, during implementation, the position of the vertical plate provided with the adsorption hole 23 is thickened.

[0033] Specifically, during implementation: the micro-hole adsorption platform 10 has a rectangular structure with rounded corners at the four corners in a top view state, and the profiling outer peripheral vertical plate 22 encloses a rectangular cavity with rounded corners at the four corners;

[0034] The base 20 is made of a material with good heat conduction performance, specifically aluminum alloy material.

[0035] The upper surface of the micro-hole adsorption platform 10 is flush with the upper plane of the outer peripheral vertical plate 22 to ensure that the ultra-thin material will not be damaged due to collision during operation;

[0036] The inner periphery of the sealing ring 30 completely covers the outer peripheral side wall of the micro-hole adsorption platform 10 to ensure that no air leakage occurs.

[0037] In a specific embodiment, the auxiliary support member is a cross support member 50 with a thickness, and all the cross support members 50 are arranged in a matrix and welded at corresponding positions on the upper surface of the bottom plate 21;

[0038] The microporous adsorption platform 10 is obtained by sintering microporous breathable alumina ceramics;

[0039] The cross support member 50 is a copper part, which ensures sufficient and reliable heat conduction.

[0040] In a specific embodiment, the pore diameter of the microporous adsorption platform 10 is within 5 to 50 um, and the distribution of the pores is bent and through in the sintered material, rather than the traditional parallel or vertical pores. The bent and through pores better reflect the hardness and support of the material, so it is more durable and has a longer service life;

[0041] The height of the sealing ring 30 is 1 to 2 mm greater than the thickness of the microporous adsorption platform 10. The upper surface of the sealing ring 30 is arranged flush with the microporous adsorption platform 10, and the lower convex height of the lower end of the sealing ring 30 is within the height space of the transition air cavity 40.

[0042] Its beneficial effects are as follows: Through the microporous adsorption platform of the microporous adsorption technology, the adsorption force is evenly distributed on the surface of the jig, ensuring that the material is evenly stressed during the adsorption process and there will be no local deformation; and because a hidden pore is formed by adopting the microporous adsorption platform, no pores can be seen on the surface of the jig, effectively avoiding the direct influence of the pores on the surface of the material, thereby preventing pits from being generated on the surface of the material. And because both the microporous adsorption platform and the base are made of materials with good heat conduction performance and a reasonable heat transfer path is designed, the temperature deviation on the surface of the jig is small, and a stable temperature environment can be provided.
