[0037] In addition, it should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0038] See Figure 1 , which is a schematic diagram of an electrolytic cell bipolar plate laser detection platform for a laser scanner provided by an embodiment of the present application.

[0039] As Figure 1 shown, the laser scanner is used to detect the bipolar plate of a proton exchange membrane fuel cell, and the laser scanner includes an electrolytic cell bipolar plate laser detection platform 100. The electrolytic cell bipolar plate laser detection platform 100 is used to place the bipolar plate; a vacuum chuck 10 is provided on the upper surface of the electrolytic cell bipolar plate laser detection platform 100. The vacuum chuck includes a vacuum chamber and a porous adsorption plane. The vacuum chamber is connected to a vacuum pump, and a sponge 11 is provided on the porous adsorption plane; a fixture 20 is provided at the edge of the electrolytic cell bipolar plate laser detection platform, and the fixture 20 is used to fix the edge of the bipolar plate.

[0040] The laser scanner provided in the embodiment of the present application can perform 3D laser scanning. The electrolytic cell bipolar plate laser detection platform fixes the edge of the bipolar plate with a clamp, increases the flatness of the bipolar plate on the electrolytic cell bipolar plate laser detection platform, and makes the bipolar plate fit with the vacuum suction cup on the upper surface of the electrolytic cell bipolar plate laser detection platform, so that the vacuum suction cup adsorbs the bipolar plate and cooperates with the clamp to fix the bipolar plate on the electrolytic cell bipolar plate laser detection platform. In this way, the vacuum suction cup with a sponge on the surface will not damage the coating on the bipolar plate, and the clamp can help to make the bipolar plate lie flat on the platform, ensuring the accuracy of the scanning measurement results.

[0041] In an embodiment of the present application, a vacuum suction cup is provided in the target area of the upper surface of the electrolytic cell bipolar plate laser detection platform. It should be noted that the target area may include the area corresponding to the reaction area of the bipolar plate, and it should be avoided as much as possible to be set at the position of the water inlet and outlet holes, because the position with holes will affect the vacuum suction cup to establish a vacuum, thereby affecting the effect of the suction cup. After the bipolar plate is placed on the electrolytic cell bipolar plate laser detection platform, the reaction area of the bipolar plate contacts the vacuum suction cup, and the sponge provided on the porous adsorption plane of the vacuum suction cup can absorb noise and reduce working noise. Moreover, due to processing reasons, there may be some warping of the bipolar plate. The sponge provided on the porous adsorption plane of the vacuum suction cup can also balance the gap between the warped bipolar plate and the suction cup to protect the coating from damage. As an example, if Figure 1 As shown, the electrolyzer bipolar plate laser inspection platform is evenly equipped with nine vacuum suction cups. Sponge sheets can be evenly bonded to the porous surface. The sponge should be made of a wear-resistant, chip-free material. The sponge sheets can be replaced regularly based on frequency of use.

[0042] like Figure 2 As shown, the clamp 20 provided in the embodiment of the present application includes a pressure plate 21, which is used to press down the edge of the bipolar plate 30 so that the bipolar plate 30 is attached to the vacuum suction cup 10 of the electrolytic cell bipolar plate laser detection platform. When the electrolytic cell bipolar plate laser detection platform is working, the clamp is pressed down after the vacuum suction cup is started. The clamp can help the product better fit on the suction cup surface. The clamp's clip is set with a limit in the vertical direction, and the lowest position of the clip is the position of the electrolytic cell bipolar plate laser detection platform. In actual applications, the four sides of the electrolytic cell bipolar plate laser detection platform can be provided with a clamp 20, and the clamp 20 is fixed to the electrolytic cell bipolar plate laser detection platform by bolts. As a possible embodiment, the clamp in the embodiment of the present application may include a pneumatic clamp.

[0043] In summary, the laser scanner provided by the embodiment of the present application uses a vacuum suction cup to adsorb the bipolar plate and cooperates with a fixture to jointly fix the bipolar plate on the laser detection platform of the electrolytic cell bipolar plate. The fixture fixes the edge of the bipolar plate, increasing the flatness of the bipolar plate on the laser detection platform of the electrolytic cell bipolar plate, so that the bipolar plate fits the vacuum suction cup on the upper surface of the laser detection platform of the electrolytic cell bipolar plate. In this way, the vacuum suction cup with a sponge on its surface will not damage the coating on the bipolar plate, and the sponge can also absorb working noise. The fixture can help place the bipolar plate flat on the platform, ensuring the accuracy of the scanning measurement results.
