In this embodiment, the detection method can detect the components involved in the automated assembly of the fuel cell stack, such as the membrane electrode and the bipolar plate 100.
The detection principle of the electric pile element identification method is as follows:
the method for identifying the cell stack elements can detect the cell stack elements in the cell stack assembly process so as to ensure the assembly quality of the cell stack, and can be used for detecting bipolar plates 100 or membrane electrodes in the cell stack assembly process in the assembly process, and particularly comprises the following steps: acquiring physical size data of the cell stack element, acquiring first image data of the cell stack element output from the camera assembly 230; if the physical size data is inconsistent with the preset physical size data of the galvanic pile element, or the first image data is inconsistent with the preset standard image data of the galvanic pile element; adjusting the relative position of the camera assembly 230 and the cell stack element and acquiring second image data of the cell stack element output from the camera assembly 230; if the second image data is consistent with the preset standard image data, judging that the retest of the galvanic pile element is qualified; and if the second image data is inconsistent with the preset standard image data, judging that the retest of the pile element is unqualified.
In the detection process, the method for identifying the electric pile elements adopts the steps of comparing the acquired physical size data and image data of the electric pile elements with preset physical size data or standard image data based on the acquired physical size data and image data of the electric pile elements so as to judge whether the electric pile elements meet the assembly requirements or not, and in the detection process, retesting is needed aiming at the electric pile elements which are unqualified in preliminary detection, so that the qualified electric pile elements can be ensured to meet the assembly requirements of the electric pile by the electric pile element identification method through two detection steps of preliminary detection and retesting, thereby improving the quality of electric pile assembly, ensuring the performance, the service life and the height size of the electric pile, reducing the procedures of manual transfer, retesting, sequencing, re-placement and the like required by retesting the qualified elements, and improving the working efficiency.

the physical size data is inconsistent with the preset physical size data of the galvanic pile element, and the first image data is consistent with the preset standard image data of the galvanic pile element;
the physical size data is consistent with the preset physical size data of the galvanic pile element, and the first image data is inconsistent with the preset standard image data of the galvanic pile element;
the physical size data is consistent with the preset physical size data of the galvanic pile element, and the first image data is consistent with the preset standard image data of the galvanic pile element;
based on the situation, the detection steps of the electric pile element identification method are as follows:

In order to obtain clear first image data during the inspection, the stack element recognition apparatus 200 further includes at least one light source 250 connected to the frame 210, and the light source 250 is used for illuminating the second recognition area and the third recognition area. That is, when the second identification area of the cell stack element is facing the camera 231, the light source 250 is used to illuminate the second identification area; when the third identification area of the cell stack element is facing the camera 231, the light source 250 is used to illuminate the third identification area.
In other embodiments of the present invention, the camera assembly 230 may further include two cameras 231, and the two cameras 231 are respectively used for outputting the first image data of the second identification area and the second image data of the third identification area of the cell stack element. The stack element recognition device 200 further includes two light sources 250 connected to the frame 210, and the two light sources 250 are respectively used for illuminating the second recognition area and the third recognition area.
Further, in the present embodiment, when the rack 210 is provided, the rack 210 may include a first bracket 211 and a second bracket 212 connected to the first bracket 211, and the first bracket 211 and the second bracket 212 together define the detection region 201; the camera assembly 230 is coupled to the first bracket 211 and the physical dimension detecting assembly 220 is coupled to the second bracket 212. The first bracket 211 is perpendicular to the second bracket 212. And the physical dimension detecting assembly 220 is located above the camera assembly 230 along the extending direction of the second bracket 212, so that the physical dimension detecting assembly 220 and the camera assembly 230 can simultaneously identify the cell stack elements located in the detection area 201.
Based on the above-mentioned cell stack element recognition apparatus 200, the embodiment of the present invention provides a cell stack element recognition system, which includes a robot arm and the cell stack element recognition apparatus 200 according to any one of the foregoing embodiments.
The robot arm is used to grasp the stack elements and adjust the relative positions of the stack elements in the detection area 201.
