Description

Technical Field

[0001] The utility model relates to the technical field of proton exchange membrane detection, in particular to a device for facilitating visual detection of defects in proton exchange membranes. Background Art

[0002] Proton exchange membrane is the core component of hydrogen fuel cell membrane electrode and water electrolysis hydrogen production equipment membrane electrode. Inside the fuel cell, the proton exchange membrane provides a channel for the migration and transportation of protons, allowing protons to pass through the membrane from the anode to the cathode, forming a loop with the electron transfer of the external circuit, and providing current to the outside world. The mainstream proton exchange membrane currently used in the market is perfluorosulfonic acid.

[0003] Due to the influence of production process and on-site environment, proton exchange membranes are prone to defects such as black spots, color difference, streaks, particles / gel particles, polymers with yellow / light brown appearance, etc. These defects can affect the performance and safety of the membrane. Therefore, the proton exchange membrane needs to be inspected for defects before it leaves the factory and before the purchaser uses it.

[0004] In terms of proton exchange membrane detection, there are currently devices for intelligent detection. For example, the Chinese invention patent with patent number 201710266195.8 discloses a thin film detection light source and a thin film detection system, including

[0005] It includes a light source housing, a light shield, an acrylic plate, a focusing rod, a light emitting diode (LED) light bar and a heat sink; the focusing rod, the LED light bar and the heat sink are inside the light source housing; it solves the problem in the prior art that the same color defects in the film cannot be obtained due to diffuse reflection of light; it achieves the effect that the image obtained by the camera can reflect the same color defects in the film, thereby improving the accuracy of film detection. This patented film detection system can quickly detect defects in the film in batches, and is more suitable for proton exchange membrane manufacturers to conduct batch detection before the products leave the factory.

[0006] However, for membrane electrode manufacturers and proton exchange membrane users, the use of proton exchange membranes is relatively small, and they are generally inspected by the naked eye. At present, when manually inspecting large-sized and sheet-shaped proton exchange membranes, it often requires the cooperation of multiple people. Generally, two people hold the two ends of the proton exchange membrane respectively, and the third person inspects the membrane. Therefore, at least three people are required to work together, resulting in low work efficiency and high labor costs.

[0007] Therefore, there is an urgent need to invent an auxiliary device that is convenient for defect detection of proton exchange membranes. Summary of the invention

[0008] Based on this, it is necessary to provide a proton exchange membrane defect visual detection device to address the technical problem of low defect detection efficiency of proton exchange membranes.

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] Proton exchange membrane defect visual inspection device, comprising:

[0011] A base, wherein two supporting rods are arranged in parallel on the base, and multiple hanging rings are vertically distributed on the outer walls of the two supporting rods;

[0012] An elastic hanging piece is detachably connected to the hanging ring, and the elastic hanging piece is used for clamping the proton exchange membrane.

[0013] By adopting the above technical solution, two elastic hangers are respectively hung on the two rods. When inspecting defects of the proton exchange membrane, the four elastic hangers are pulled up to clamp the four corners of the proton exchange membrane respectively, and the elastic force of the elastic hangers is used to pull the proton exchange membrane to fully unfold. Then the inspector can perform a visual inspection of the proton exchange membrane. The operation can be completed by one inspector, and the operation is simple, saving time and effort.

[0014] In addition, a plurality of hanging rings are vertically distributed on the support rod. According to the width of the proton exchange membrane to be tested, a hanging ring of the elastic hanger on the support rod is selected. The height of the elastic hanger on the support rod is adjustable to adapt to proton exchange membranes of different widths.

[0015] Preferably, the elastic hanging part comprises a lock buckle, an elastic rope and a clip, two ends of the elastic rope are respectively connected to the lock buckle and the clip, the lock buckle is hung on the hanging ring, and the clip can clamp the proton exchange membrane.

[0016] By adopting the above technical solution, after the lock buckle is hung on the hanging ring, due to the elastic force of the elastic rope, the clamp can be flexibly moved to adapt to proton exchange membranes of different sizes. The corners of the proton exchange membrane can be clamped by pulling the clamp, and the proton exchange membrane can be fully unfolded by relying on the resilience of the elastic rope.

[0017] Preferably, the base is in the shape of an elongated strip, and a row of insertion holes is provided on the top of the base, and the two support rods are both detachably inserted into the insertion holes.

[0018] By adopting the above technical solution, a row of sockets is set. When the length of the proton exchange membrane to be detected is long, the two rods are inserted into the two relatively farthest sockets on the base. When the length of the proton exchange membrane to be detected is short, the two rods are inserted into the two relatively close sockets on the base. That is, the position of the sockets of the two rods on the base can be used to adapt to proton exchange membranes of different lengths, and the operation is flexible.

[0019] Preferably, both support rods are telescopic rods.

[0020] By adopting the above technical solution, the support rod can be easily stored after being disassembled from the base.

[0021] Preferably, grooves are provided on the top of the base along both sides of the row of sockets, and the two grooves are used to place the two support rods respectively.

[0022] By adopting the above technical solution, the groove is used to store two rods. After the two rods are pulled out from the base, they can be directly placed in the groove, which is convenient and practical.

[0023] Compared with the related art, the proton exchange membrane defect visual detection device provided by the utility model has the following beneficial effects:

[0024] 1. The proton exchange membrane defect visual inspection device of the utility model is provided with a hanging ring and an elastic hanger on the support rod. The four corners of the proton exchange membrane are clamped by the four elastic hangers, and the proton exchange membrane is pulled to fully unfold. Then the inspector can perform a visual inspection of the proton exchange membrane. The operation can be completed by one inspector, and the operation is simple, saving time and effort.

The tester does not need to hold the proton exchange membrane 5, which reduces the workload of the tester, and only one person is needed to complete the test work.

[0034] A plurality of hanging rings 3 are vertically distributed on the support rod 2. According to the width of the proton exchange membrane 5 to be tested, a hanging ring 3 of the elastic hanging member 4 on the support rod 2 is selected.
