Abstract
Description
Technical Field
[0001] The utility model relates to the field of ultra-high flatness detection of pole plates, and in particular to an ultra-high flatness detection device for pole plates. Background Art
[0002] The bipolar plate is the core component of hydrogen fuel cells. It plays the role of evenly distributing reactants, discharging product water, collecting current, cooling and supporting in fuel cells, and has a very important impact on the performance of fuel cells.
[0003] At present, the metal bipolar plates commonly used in the market are manufactured by stamping and then laser welding (PVD coating is also involved in the process). Stamped metal monopolar plates, PVD-coated monopolar plates / bipolar plates, and laser-welded metal bipolar plates will warp and deform due to uneven material structure, uneven stress distribution during deformation, and uneven thermal stress during coating and welding. The warping and deformation of metal bipolar plates will have an adverse effect on the distribution of assembly force of the battery stack, resulting in large differences in contact resistance in different areas of the same plate, resulting in different outputs at different positions of the plate and uneven temperature distribution, which not only affects the working performance of the battery stack, but also produces local hot spots. In severe cases, it can even cause breakdown of the membrane electrode and damage the entire battery stack.
[0004] Furthermore, the dimensional error and shape error of the bipolar plate affect the contact resistance of the stack and the material distribution on the performance of the stack by affecting the contact mechanical behavior of the stack. In a single-layer battery structure, the poor contact behavior between the bipolar plate and the gas diffusion layer will increase the contact resistance and affect the uniformity of the reaction, thereby reducing the performance and life of the stack. The contact stress of the gas diffusion layer affects the performance of the stack. If the contact stress is too low, the contact resistance increases rapidly, thereby reducing the performance of the battery; on the other hand, if the contact stress is too large, it may cause structural damage to the gas diffusion layer and reduce the reaction efficiency. Therefore, reasonable and uniform contact stress is an important factor for the stable operation of the stack. For metal bipolar plates with processing errors, each flow channel is subjected to different forces, which causes different contact stresses between the single flow channel and the gas diffusion layer, which also leads to uneven distribution of contact stress of the entire gas diffusion layer. Therefore, controlling the flatness of the fuel cell plate is crucial to improving the performance and life of the stack. Utility Model Content

[0033] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.
[0034] Combine the following Figures 1 to 5 The electrode plate ultra-high flatness detection device 10 provided in this embodiment is described in detail.
[0035] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The embodiment of the utility model provides a plate ultra-high flatness detection device 10, including a body 100, a plate placement plate 200 for testing, an XY module 300, a beam switch 400 and a laser rangefinder 500, wherein the plate placement plate 200 for testing is used to place the plate to be tested; the XY module 300 is fixed on the body 100, the plate placement plate 200 for testing is fixed on the XY module 300, and the XY module 300 is used to drive the plate placement plate 200 for testing to move along the X direction and Y direction in the horizontal plane. The beam switch 400 is fixed on the machine body 100, and the beam switch 400 is used to detect whether the plate on the plate placement plate 200 to be tested, which is driven by the XY module 300 to move along the X direction and the Y direction, is too high; the laser rangefinder 500 is fixed on the machine body 100, and the laser rangefinder 500 is located above the XY module 300, and the laser rangefinder 500 is used to detect the height value of the plate on the plate placement plate 200 to be tested, which is driven by the XY module 300 to move along the X direction and the Y direction.
[0036] The beam switch 400 is used to measure whether the plate is too high. If it is too high, it does not meet the standard. If it is not too high, it passes the test. The laser rangefinder 500 is used to measure the height value of the specified position of the plate to specifically determine the height of the specific position. The plate is placed on the plate placement plate 200 to be tested, and the XY module 300 drives the plate placement plate 200 to be tested to drive the plate to move along the X direction and the Y direction, and the laser emitted by the beam switch 400 is used to complete the super-high detection. Then the XY module 300 drives the plate placement plate 200 to be tested to drive the plate to move along the X direction and the Y direction, and locate it to different coordinates, and the laser rangefinder 500 detects the height of each preset position of the plate. When the beam switch 400 passes the super-high test, the laser rangefinder 500 is used to specifically detect the position of the super-high position and record it. When the beam switch 400 passes the test, the laser rangefinder 500 is used to detect the height of each specified position to form correction data.
[0037] The positions of the beam switch 400 and the laser rangefinder 500 remain unchanged throughout the entire process. The XY module 300 only needs to adjust the plate placement plate 200 to drive the plate to be tested to move along the X direction and the Y direction, and move the plate to different coordinates and positions, so that the beam switch 400 and the laser rangefinder 500 can measure the height of different positions on the plate to achieve comprehensive detection. The beam switch 400 is combined with the laser rangefinder 500 to improve detection efficiency and accuracy.
[0038] It should be noted that the X direction refers to the direction indicated by the arrow X in the figure, and the Y direction refers to the direction indicated by the arrow Y in the figure. Specifically, the X direction refers to the longitudinal direction, and the Y direction refers to the transverse direction.
[0039] Reference Figure 5 In this embodiment, the laser rangefinder 500 is arranged downstream of the beam switch 400; the laser rangefinder 500 is used to detect the plate detected by the beam switch 400. The plate is placed on the plate placement plate 200 to be tested, driven by the XY module 300, and firstly the beam switch 400 is used to detect whether it is over-height, and then it is moved under the laser rangefinder 500 to detect the height value.
[0040] In this embodiment, the beam switch 400 and the laser rangefinder 500 are arranged side by side and spaced apart along the X direction. The XY module 300 drives the plate to move along the X direction, first passing through the beam switch 400 for detection, and then moving to the bottom of the laser rangefinder 500 for height detection.

[0042] The plate is located between the transmitter 410 and the receiver 420. The XY module 300 drives the plate to move between the transmitter 410 and the receiver 420 along the X direction and the Y direction to detect whether different positions of the plate are super-high. The transmitter 410 emits a laser to the receiver 420. If the receiver 420 can receive the laser, it means that the plate is not super-high and meets the standard, and it continues to move to the laser rangefinder 500 for the next step of detection. If the receiver 420 does not receive the laser, it means that the plate is super-high and does not meet the standard, and it continues to move to the laser rangefinder 500 for the next step of detection. Regardless of whether the plate's beam switch 400 detects super-high or not, it is necessary to perform detection by the laser rangefinder 500 in order to collect specific data for subsequent analysis.
